Flip-Flow Screen Topic

The flip flow screen is a screening machine that throws materials through the relaxation and tension movement of the elastic screen surface installed on the inclined screen box. It is a screening equipment widely used in the industrial field. It realizes the classification and screening of materials through the principle of vibration and is suitable for screening operations of various materials. The main characteristics of the flip flow screen are improved screening efficiency, large processing capacity, small dynamic load, low power consumption and low noise.

Flip-Flow Screen

The flip flow screen is mainly composed of a crankshaft connecting rod, a chassis, a supporting leaf spring, an inner mesh screen frame, a crossbeam, a rubber plastic screen plate, a hollow rubber spring, etc. The screen is made of a retractable polyurethane rubber material. When working, the screen is alternately tightened and relaxed, so that the material bounces forward, which can prevent the material from adhering to the screen or clogging the screen holes, thereby achieving the classification of the material.

The flexible screen plate is used to make the ejection acceleration reach 30 to 50 times the acceleration of gravity, and the maximum amplitude of the screen plate is 40 mm. The material is not easy to adhere to the screen surface or clog the screen holes. It has high screening efficiency, large processing capacity, small dynamic load, low power consumption and low noise. It is widely used for grading garbage with a water content of 7% to 14% and high viscosity, ore, coal, gravel, fertilizer, slag, urban garbage, etc., and is especially suitable for deep screening of medium and fine-grained coal.

The flip flow screen is mainly composed of a screen box, a vibrator, a support spring and a base. The screen box is the main working part of the flip flow screen, and the material is screened in the screen box. The vibrator is a device that generates vibration, usually driven by a motor. The support spring connects the screen box and the foundation to play a shock-absorbing and supporting role. The base is used to fix the vibrator and the support spring to ensure the stable operation of the screen machine.

The flip flow screen (also called an elastic screen or a resonance screen) is a special type of vibrating screen that uses the resonance characteristics of the material at a specific frequency to achieve efficient screening. The design and working principle of the flip flow screen are different from those of the traditional vibrating screen. The main feature is to enhance the screening effect by causing a large elastic deformation of the screen surface.

The flip flow screen is a new type of screening machine that can screen materials with high viscosity and moisture, as well as fine, sticky and wet materials. If the screened material contains materials that are easy to clog the screen, the flap screen can achieve very high screening efficiency with a smaller screen area. Therefore, the flap screen is widely used in environmental protection, coal, mining, coal preparation machinery and other fields.

The main features of the flip flow screen include efficient dehydration and high screening accuracy. It can effectively remove moisture from the material and improve the dryness of the material. By adjusting the vibration frequency and amplitude, accurate screening effects can be achieved to meet different particle size requirements.

Flip-Flow Screen

The flip flow screen has a simple structure and is easy to use, so it is also widely used in laboratory particle analysis. According to different screen apertures and speed settings, the flap screen can achieve screening requirements for different particle sizes, and the required particles can be easily obtained through the collection container.

The flip flow screen is a dry screening equipment specially designed for bulk, wet and sticky fine materials. It is widely used in environmental protection, coal, chemical industry, mining, electricity, coke, metallurgical building materials and other fields. For example, it is used in the screening of iron-making raw materials and sticky block ore under the blast furnace trough, which can greatly meet the requirements of iron-making raw material plants and customers under the blast furnace trough for large screening processing capacity and good screening effect of sticky block ore.

The flip flow screen is a dual-mass vibration system that uses polyurethane rubber screen surface. Any two adjacent beams supporting the screen surface belong to two vibrating mass bodies respectively. One of the mass bodies is the screen box and the other mass body is the supporting body. Heavy. When working, the screen mesh alternately tightens and relaxes, causing the material to bounce forward, which can prevent the material from adhering to the screen mesh and blocking the screen holes. When the two masses vibrate with two phases, any two adjacent beams sometimes approach and sometimes move away from each other, and the elastic screen surface also relaxes and tightens accordingly, that is, the screen surface moves along with the screen box, and at the same time, it also moves relative to the screen box. make relative motion. This relaxation movement not only causes the screen holes to continuously deform, but also greatly increases the vibration intensity of the screen surface, thereby effectively overcoming the clogging of the screen holes and significantly improving the processing capacity of the screen machine. However, because the vibration intensity of the screen box is not large, the mechanical strength is easy to ensure, but the vibration intensity of the screen surface is large and it is repeatedly deformed, so the life of the screen surface is low.

The flip flow screen combines the structural characteristics of the complex frequency screen and the flip flow screen, creatively combining the variable frequency and amplitude with the dynamic and static screen box, so that the screen surface can do both high-amplitude and low-frequency relaxation and relaxation movement and high-frequency and low-amplitude relaxation movement. Each section of the screen surface adjusts the movement state according to the viscosity characteristics of the material to ensure that the screening movement is in the best state, so that the wet and sticky material does not block the hole and achieves a higher screening efficiency.

PS: The flip flow screen has excellent performance in handling some difficult-to-screen materials with its unique resonance screening method. The flip flow screen is an efficient, energy-saving and environmentally friendly screening equipment with broad application prospects and development potential. It provides a more efficient and reliable solution for industrial production.

The working principle of the flip flow screen is relatively complex but efficient. It is mainly based on the combination of vibration force and relaxation motion of the screen surface to achieve material screening. The following is an introduction to the working principle of the flip flow screen by the editor of Zhongcheng Machinery:

1. Basic working principle: The flip flow screen uses the vibration force and surface tension (or relaxation tension) on the screen to separate solid particles from liquid or mixed materials. During the screening process, liquid or fine particles flow through the pores of the screen, while larger solid particles are retained on the screen because they cannot pass through the pores of the screen, thereby achieving solid-liquid or solid-solid separation.

2. 
   

Flip-Flow Screen Working Principle

2. The role of vibration force: The flip flow screen usually generates vibration force through a vibrating machine (such as a vibrator). The vibration force will cause the solid particles on the screen to generate inertial force, causing them to jump on the screen. This jumping motion helps the solid particles gradually move to the upper layer on the screen to form a particle layer with moderate thickness. This can not only improve the screening efficiency, but also prevent the screen from being blocked.

3. Effect of relaxation motion: The screen surface of the flip flow screen (usually made of materials such as elastic polyurethane) will continuously expand and contract under the action of vibration force. This relaxation motion causes the screen surface to vibrate at a high frequency (such as hundreds of times per minute), thereby obtaining a high acceleration (such as 50g or higher). This high acceleration can effectively prevent the blockage of the screen holes and promote the rapid screening of materials on the screen surface.

4. Screening process:

a. Feeding: The solid-liquid mixture or mixed material enters the screen surface area of the flip flow screen through the feed port.

b. Screening: Under the action of vibration force and relaxation motion, the material is screened on the screen surface. The solid particles are subject to the tension and vibration force of the screen surface, jumping and rolling on the screen surface, and gradually separated into different layers. Fine particles fall into the collection trough or discharge port below through the pores of the screen, while larger particles are blocked above the screen.

c. Discharge: The screened material is discharged through different discharge ports. Solid particles and liquids are collected and processed separately.

PS: The working principle of the flip flow screen is based on the combination of vibration force and relaxation movement of the screen surface, and the separation and collection of materials are achieved through an efficient and stable screening process. Its unique screening method and superior performance have made it widely used and recognized in the industrial field.
