 I. Features of the bar screen cleaner are as follows:

  1. The advantages of the bar screen cleaner are high degree of automation, high separation efficiency, low energy consumption, no noise, and good corrosion resistance. It can ensure continuous and stable operation without unattended operation. It is equipped with an overload safety protection device, which will automatically shut down when the equipment malfunctions to avoid equipment overload.

  2. The bar screen cleaner can adjust the equipment operation interval according to user needs to achieve periodic operation; it can be automatically controlled according to the liquid level difference before and after the bar screen; and it has a manual control function, which is convenient for maintenance. Users can choose according to different work needs. Due to the reasonable structure design of the equipment, the equipment has a strong self-cleaning ability during operation and will not be blocked, so the daily maintenance workload is very small.

  3.Bar screen cleanerIt consists of a frame, traction chain, transmission system, gear rake assembly A, gear rake assembly B, underwater guide wheel assembly, water auxiliary screen, screen bars, etc.

  II. The structure of the bar screen cleaner is as follows:

  1. The bar screen cleaner is an integral structure and can be assembled and debugged on a special platform. It can only be delivered after 8 hours of empty machine debugging to ensure assembly quality and simplify on-site installation work.

  2. A movable auxiliary screen is added in front of the main screen bar of the bar screen cleaner. The spacing of the movable auxiliary screen is consistent with the spacing of the main screen bar. The screen residue of the movable auxiliary screen is scooped out by the long rake teeth, effectively preventing the screen residue in the sewage from passing through the bottom of the screen bar and the accumulation of bottom sediment.

  3. The chain adopts a special wide-plate stainless steel chain with a safety factor of no less than 6, and is equipped with a chain wheel tensioning adjustment device. When running in the chain trough, no other slag-blocking device needs to be added, which can effectively prevent the screen residue from winding in the chain trough and avoid blockage.

  4. The transmission mechanism is installed on the top of the frame, using a horizontal cycloidal pinwheel reducer, and is equipped with an over-torque protection device (shear pin), which can effectively prevent the motor reducer from being overloaded and damaged. It is equipped with a protective cover, which is easy to disassemble.

  5. The cleaning rake teeth are of two types: one is a long rake and the other is a rake. The long rake has a large amount of slag.

  6. This machine is equipped with an overload protection device. When the machine malfunctions or is overloaded, it will automatically stop and alarm. This system is sensitive and reliable.

  7. The working principle of the bar screen cleaner is that the rake teeth are fixed on the chain, and the chain runs along the guide rail. The rake teeth go down from the rear of the screen and run from the bottom of the screen to the front of the screen. From bottom to top, the floating objects intercepted by the screen are dredged to the slag discharge port along the baffle and then discharged into the slag truck. The control system is fully automatic and can automatically start and stop according to the time. When torque occurs, it will alarm in time and immediately stop automatically.
