The working principle and advantages of Zhongcheng flip-flop screen

Zhongcheng flip-flop screen uses dual vibration to screen difficult to screen materials, without clogging the holes, and is highly efficient. Highlights include wear-resistant screen mesh, compact design, modular structure, self-cleaning, low energy consumption, and high reliability. Suitable for the treatment of aged, decorated, and mixed household waste.

Zhongcheng flip-flop screen is a device used for screening difficult to screen materials such as fine, sticky, and wet materials. It generates dual vibrations through a single drive, and the sieve mesh changes along with the stretching and shrinking deformation during the reciprocating motion of the screen mesh. Therefore, when screening materials with high humidity, the sieve mesh will not block the holes, achieving very high screening efficiency with a relatively small screen mesh area. Therefore, it is widely used in aged garbage, decoration garbage, and mixed household garbage.

1. Working principle of Zhongcheng flip-flop screen:

Double body near resonance principle: The flip-flop screen adopts the double body near resonance principle, and a single drive generates dual vibrations. The main vibrating screen frame is driven by excitation force to perform basic vibration, and the floating screen frame and the main vibrating screen frame are connected to a shear spring to perform relative motion in a near resonance state.

Mesh expansion: One end of the polyurethane mesh is fixed on a fixed crossbeam, and the other end is fixed on a floating crossbeam. The relative motion between the fixed beam and the floating beam causes the mesh to continuously expand and contract, transmitting very high acceleration to the material, allowing it to be fully thrown and layered.

High acceleration: The sieve can transmit an acceleration of up to 50g to the material, allowing it to fully loosen and pass through the sieve, completing the screening process.

2. Characteristics of Zhongcheng flip-flop screening Technology:

a. Non welded wall panel: The screening machine wall panel is non welded and assembled using high-strength alloy steel plates and imported HUCK rivets for hydraulic tightening, eliminating residual welding stress.

b. Optimize structure: Optimize the structure and vibration parameters of the screening machine through finite element analysis, avoid natural frequencies at all levels, reduce resonance effects, and extend the service life of the entire machine.

c. Adjustable amplitude: The amplitude of the floating screen frame can be adjusted by changing the number of shear springs.

d. Efficient exciter: Adopting an efficient helical gear box type exciter, it has the characteristics of super large excitation force, ultra-low noise, smooth operation, and long service life.

e. Self cleaning function: The polyurethane screen adopts a press in installation, which is easy to replace. The elastic deformation has the function of self-cleaning the screen holes, effectively solving the problem of clogging of fine, wet and sticky materials.

3. Application scenarios and advantages of Zhongcheng flip-flop screening.

Application scenario: Widely used in dry screening operations for difficult to screen materials such as medium to fine-grained, wet, and viscous materials.

Product advantages: not easy to block holes, high screening efficiency, large processing capacity.

4. Characteristics of Zhongcheng flip-flop screening.

a. Dynamic wear-resistant screen design reduces maintenance and improves screening efficiency.

b. Compact and highly integrated design, occupying less space.

c. Modular structure makes screening parameter adjustment more convenient and flexible.

d. The high excitation intensity ensures self-cleaning effect, and the sieve holes are less likely to clog.

e. The same screening area results in lower energy consumption.

f. The highly reliable eccentric flywheel exciter has a large load-bearing capacity and a long service life.

g. High screening efficiency for wet garbage.

Summary: Zhongcheng flip-flop screen is an efficient, energy-saving, and environmentally friendly screening equipment widely used in various fields such as garbage sorting, coal, electricity, chemical industry, and building materials. It adopts a unique tension screen design, which can achieve fine screening of various materials, improve screening efficiency, reduce energy consumption and costs. The sieve mesh of the galloping screen is made of high-strength materials, which have high elasticity and durability, and can withstand high-speed vibration and the impact of a large amount of materials. In addition, the galloping screen has the characteristics of high screening efficiency, large processing capacity, low dynamic load, low power consumption, and low noise, making it particularly suitable for screening wet materials. In summary, the  flip-flop screen has broad application prospects and market potential, making important contributions to industrial production and environmental protection.
