Application status and development trend of trommel screen for waste screening

Trommel screens screen garbage and have a wide range of applications and significant advantages in the current field of garbage treatment. The following is a detailed analysis of its current situation:

A. Current application status of trommel screen for garbage screening

1. Municipal solid waste treatment: As a front-end sorting equipment, the trommel screen plays an important role in urban solid waste treatment plants. It can effectively separate bulky waste, hazardous waste and small waste, providing convenience for subsequent processing and improving overall processing efficiency.

2. Construction waste recycling: In construction waste recycling stations, trommel screens can separate impurities in building materials, such as bricks, stones, etc., thus promoting the reuse of resources.

3. Organic waste treatment: In the organic waste treatment center, the drum screen can remove inorganic impurities and create conditions for biodegradation and composting.

B. Technical characteristics and advantages of trommel screen for garbage screening

1. High-efficiency screening: The trommel screen uses the rotation of the cylinder and the built-in lifting plate to lift the materials to a certain height and then naturally fall down, using the differences in shape, size and weight of the materials to achieve separation. This screening method is efficient and continuous and can handle large amounts of waste.

2. Strong adaptability: The drum screen is suitable for many types of solid waste, including construction waste, organic waste, etc. Its screening efficiency and accuracy are excellent in different types of waste.

3. High degree of automation: The trommel screen is usually equipped with an automated control system, which can realize remote monitoring and automatic adjustment of the equipment, reducing the difficulty and cost of manual operation.

4. Environmental protection: The trommel screen reduces the need for manual sorting, reducing labor intensity and environmental pollution. At the same time, mechanical screening can also reduce the environmental pollution of garbage, especially the separation of harmful substances, which can effectively prevent them from entering the natural environment.

C. Development trend of trommel screen garbage screening

1. Intelligentization: With the continuous advancement of technology, trommel screens will pay more attention to intelligent development. By introducing technologies such as sensors and the Internet of Things, real-time monitoring and data analysis of equipment can be achieved to improve screening efficiency and accuracy.

2. Efficiency: In the future, drum screens will pay more attention to improving screening efficiency and achieve more efficient and accurate garbage screening by optimizing equipment structure and improving screening processes.

3. Diversification: For different types of garbage, the drum screen will develop in a diversified direction. Through the development of drum screens of different models and specifications, we can meet the garbage screening needs in different scenarios.

D. Challenges faced by trommel screens in screening waste

1. Equipment failure and maintenance: Long-term operation of the trommel screen may cause problems such as loose bolts, screen clogging, and wear. To ensure the normal operation of the equipment, regular equipment inspection, maintenance and upkeep work is required.

2. Operation and maintenance costs: Although the trommel screen has the characteristics of high efficiency and automation, its operation and maintenance costs are also relatively high. Professional operators and maintenance personnel are required to ensure the normal operation and extended service life of the equipment.

The following is the basic knowledge of a trommel screen:

E. Knowledge of trommel screen

The trommel screen is a widely used machine in sorting technology. It controls garbage sorting by controlling the particle size, and has high sorting accuracy. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. The sieve holes are arranged from small to large, and the sieve holes on each section have the same diameter. The drum screen mainly consists of motor, reducer, drum device, frame, sealing cover, and inlet and outlet.

F. Knowledge of trommel screen

The roller device is installed obliquely on the frame. The motor is connected to the drum device through the reducer through a coupling, and drives the drum device to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is flipped and rolled, so that the qualified material (screened products) is discharged through the outlet at the bottom of the rear end of the drum, and the unqualified material (screened product) The upper product) is discharged through the discharge port at the rear of the drum. Due to the flipping and rolling of materials in the drum, materials stuck in the screen holes can be ejected to prevent the screen holes from being blocked. The principle and structure of drum sand screening machine, drum screening machine and drum screen are almost the same, but there are differences in people's understanding and name of them.

G. Characteristics of trommel screen

1. The sieve holes are not easily blocked.

2. Smooth operation and low noise.

3. Simple structure and easy maintenance.

4. The screening cylinder can be closed, making it easy to seal and collect dust.

5. The whole machine has high reliability and less one-time investment.

6. Using special screen mesh, it has high screening efficiency and long service life.

H.Application scope of trommel screen

1. Garbage screening industry.

2. Used for sand and gravel separation in sand and gravel fields.

3. In the coal industry, it is used for separation of lump coal and coal powder and coal washing (component of coal washing machinery).

4. In the chemical industry and mineral processing industry, it is used to classify large and small lumps and separate powdery substances.

5. Used in stone quarries to classify large and small stones and separate soil and stone powder.

PS: Trommel screen waste screening has wide applications and significant advantages in the current field of waste treatment. With the continuous advancement and innovation of technology, drum screens will become more intelligent, efficient and diversified, contributing to building a green and sustainable society. We must also pay attention to the challenges and problems it faces, strengthen equipment maintenance and management, and ensure its long-term stable operation.
