Description

Technical Field

[0001] This utility model relates to the field of pipeline sludge treatment technology, specifically a vibrating screen applied to pipeline sludge treatment systems. Background Technology

[0002] With the acceleration of urbanization, urban drainage pipe systems are facing increasing pressure in sludge treatment. The sludge in the pipes contains large pieces of garbage, stones, and wood chips, etc. If these debris are not effectively separated in the early stages of treatment, they will cause serious damage to subsequent treatment equipment and reduce treatment efficiency.

[0003] Traditional vibrating screens have many drawbacks when processing sludge from pipes and channels. First, their complex structure makes maintenance difficult, and once a malfunction occurs, repair costs are high and time-consuming. Second, they cannot withstand the impact load of automatic unloading by sludge transport vehicles, and are prone to overload damage, affecting the continuity of the processing system. Third, the screen material and structure are not optimized, resulting in low screening efficiency, and they are prone to wear in harsh working environments, requiring frequent replacement.

[0004] Some existing vibrating screens fail to adequately consider the complex characteristics of sludge in pipe and channel systems, resulting in poor screening efficiency and failing to meet the high-efficiency screening requirements of pipe and channel sludge treatment systems. These problems highlight the necessity of improving vibrating screen design, necessitating a new type of vibrating screen to address these issues. Utility Model Content

[0018] The discharge port of the screen body is equipped with an adjustable baffle to control the discharge speed and direction of the material.

[0019] The aforementioned vibrating screen is used in pipeline sludge treatment systems.

[0020] The shaft of the vibrating motor has an inclination angle relative to the screen surface to enhance the screening effect;

[0021] The bottom of the screen body is equipped with adjustable support legs for adjusting the levelness and height of the screen body.

[0022] The aforementioned vibrating screen is used in pipeline sludge treatment systems.

[0023] The screen edge is equipped with a sealing device to prevent material leakage;

[0024] The screen body is provided with an inspection door on the side, which facilitates the maintenance and replacement of internal components;

[0025] The top of the screen body is equipped with a dust cover to reduce dust emissions and improve the working environment.

[0026] Furthermore, in the aforementioned vibrating screen applied to the sludge treatment system for pipes and channels,

[0027] The control system of the vibrating screen includes an overload protection device that automatically stops the machine and alarms when the equipment load exceeds the set value.

[0028] The screen surface is coated with a wear-resistant coating to extend the service life of the screen.

[0029] The screen body is equipped with a noise reduction device to reduce the noise during equipment operation;

[0030] The screen body is equipped with a protective railing to ensure the safety of operators;

[0031] The vibrating screen is connected to other equipment in the pipeline sludge treatment system via pipelines to achieve automated continuous operation.

[0032] The vibrating screen proposed in this utility model has the following advantages and features:

[0033] 1. High-efficiency screening and stable operation: Utilizing a dual-vibration motor drive, the screen body moves in a linear trajectory. Combined with a well-designed screen mesh, this efficiently separates and removes large pieces of garbage, stones, and wood from sludge in pipes and channels. This design not only improves screening efficiency and ensures the smooth operation of subsequent processing steps, but also enhances the stability and consistency of the screening effect by optimizing the inclination angle of the vibration motor shaft and the screen structure.

[0034] 2. Durability and Adaptability: The main components of the screen body are made of SUS304 stainless steel, combined with polyurethane screen mesh and high-quality spring steel shock-absorbing springs, giving the equipment excellent corrosion resistance and wear resistance. This not only extends the service life of the equipment but also ensures that it can adapt to the complex working conditions in the pipeline sludge treatment process, including withstanding the impact load during the automatic unloading of sludge transport vehicles, avoiding overload damage, and ensuring stable operation of the equipment under high-load conditions.

[0035] 3. Convenient maintenance and reduced costs: The equipment has a simple structure, making it easy for operators to perform daily maintenance and repairs, thus reducing maintenance difficulty and costs.

The sludge storage tank 10 is semi-underground. Transport vehicles dump sludge from the pipeline into the semi-underground pipeline sludge storage tank 10 for receiving and storing feed.

[0043] like Figure 2 , Figure 3As shown, the vibrating screen is a key component of the system, and its specific structure and operation are as follows: The vibrating screen consists of a screen body, two vibrating motors, and a screen mesh. The vibrating motors are mounted on the screen body, and the screen mesh is tensioned on the screen body. The screen mesh is made of polyurethane, which has good wear resistance and screening effect. Its grid gap is 100×100mm, the effective filtration size is 6760×1570mm, and the horizontal inclination angle is 5 degrees. Except for the support legs, which are made of Q235 carbon steel for corrosion protection, the rest of the screen body is made of SUS304 stainless steel. The shock-absorbing springs are made of high-quality spring steel with an outer diameter ≥90mm and a wire diameter ≥10mm. The screen mesh edge of the vibrating screen is equipped with a sealing device to prevent material leakage; the feed inlet of the screen body is equipped with a guide device, and the discharge outlet is equipped with an adjustable baffle to facilitate control of material distribution and discharge speed. The control system of the vibrating screen includes an overload protection device, which automatically stops the machine and alarms when the equipment load exceeds the set value. The vibrating screen is connected to other equipment in the pipeline sludge treatment system through pipelines to achieve automated continuous operation.

[0044] During operation, sludge transport trucks dump sludge from the pipes onto the vibrating screen. After the vibrating motor starts, the excitation force generated by its eccentric blocks causes the screen body to move linearly. Under the combined force of the excitation force and the material's own weight, the material is thrown up on the screen surface and moves forward in a straight line. Large pieces of garbage, stones, and wood, due to their size being larger than the screen mesh, remain on the screen surface and are eventually discharged; while smaller sludge particles fall through the screen and enter subsequent processing steps. The effective screening by the vibrating screen improves the efficiency and effectiveness of the entire pipe sludge treatment system.
