Principle and application of rotary screen cleaner

The rotary mechanical grid mainly includes frame, drive speed system, drive guide wheel, supporting wheel and closed rotary traction chain, tooth rake and grid bar Driven by the motor reducer, the rotary traction chain rotates from the bottom to the top When the rake tooth shaft on the traction chain is transported to the water face of the grid bar, the rake tooth is inserted into the gap of the grid bar to clear from the bottom to the top, scraping the debris on the grid bar off the rake Because the tooth rake is designed to form an included angle between the two teeth of the double tooth rake, when one tooth is inserted into the gap of the grid bar for dredging, the other tooth will surround the solid debris with the surrounding potential, so as to prevent it from leaking out, and the cleaning efficiency is high and thorough When the tooth rake is transported to the upper part of the machine, the sundries will fall off the container or conveyor by their own weight, and then they will be sent away At the same time, in the design, considering that: 1 Sundries may enter into the traction chain, and the traction chain is stuck, so the closed traction chain is designed 2 The underwater shaft components are made of stainless steel with nylon bearings, which avoids the routine maintenance of underwater components Features and service conditions: 1 The grid bars of the rotary screen cleaner are placed in the middle of the drag chain of the rake teeth (other rotary screen cleaners are placed under the drag chain), which changes the movement direction of the rake teeth in the process of dredging (opposite to other grids), and prevents the hard objects from being brought into the bottom to block the rake teeth and the drag chain 2 The equipment adopts rotary traction chain, which is mainly composed of chain plate, chain pin and roller During operation, the guide rail on the rack is used as the guide rail, and the roller is used for rolling movement on the guide rail, so as to avoid the trouble of disorderly rope of wire rope traction grid cleaner 3 The rotary screen cleaner can adjust the operation interval of the equipment at will according to the user's needs to achieve periodic operation It can be automatically controlled according to the liquid level difference between the front and back of the grid, and has the function of manual control, which is convenient for maintenance The device also has a starting device, which will generate an audible and visual button in case of machine failure Users can choose according to different work needs 4 In order to avoid the damage to the equipment caused by the impact load, the overload safety protection device is designed and installed on the sprocket plate at the output shaft end of the reducer The main advantages of rotary grid decontamination machine are high automation, high separation efficiency, small power consumption, no noise, good corrosion resistance It can ensure continuous and stable operation under unattended condition It is equipped with overload safety protection device, which will automatically shut down in case of equipment failure and avoid overload operation The equipment can adjust the operation interval of the equipment according to the user's needs to achieve periodic operation; it can be automatically controlled according to the liquid level difference between the front and the back of the grid; and it has manual control function to facilitate maintenance Users can choose according to different work needs.
