[0021] In the embodiments of this application, such as Figure 1 , 2 As shown in 3, 4, 5, 6 and 7, an automatic cleaning device for bar screen slag includes a support frame 3 located on top of the sewage bar 101. The support frame 3 is made of stainless steel welded together.

[0022] The support frame 3 has a mounting frame 1 welded to its side. The mounting frame 1 is U-shaped and has a cleaning component 2 inside. The cleaning component 2 is located directly above the garbage conveyor 102 to ensure that the cleaned grid residue can fall directly onto the conveyor.

[0023] Both the sewage bar 101 and the garbage conveyor 102 are based on the existing structure of the grid cleaning machine. For details, refer to the existing rotary grid cleaning machine. Their working principle and specific structure are existing technologies, so they will not be described in detail in this application.

[0024] The bottom end of the support frame 3 is welded with a slag-collecting plate 9. The slag-collecting plate 9 is made of 316L stainless steel plate, which has the characteristics of being resistant to sewage corrosion. It is located at the bottom of the sewage grate 101. The toothed rake of the sewage grate 101 is close to the top surface of the slag-collecting plate 9. The toothed rake and the slag-collecting plate 9 work together to facilitate the retrieval and conveying of slag in the sewage.

[0025] The top of the slag tray 9 is bent to a horizontal state by cold bending, and a cleaning trough 10 is opened in the horizontal part. The cleaning trough 10 is a rectangular through trough located directly above the garbage conveyor 102. The sewage grid 101 is set along the curved surface of the slag tray 9 and passes over the cleaning trough 10 and the cleaning component 2 in sequence. After the slag is conveyed to the cleaning trough 10 through the sewage grid 101, it can fall directly into the cleaning trough 10 and finally fall into the garbage conveyor 102 and be sent away.

[0026] Furthermore, the cleaning component 2 includes two rotating grooves 201, which are circular grooves formed on opposite sides of the mounting bracket 1. Rotating rods 202 are inserted into the interior of the two rotating grooves 201, and the rotating rods 202 are connected to the rotating grooves 201 via bearings.

[0027] An installation cylinder 203 is fixed on the circumferential surface of the rotating rod 202. The installation cylinder 203 is located between two rotating slots 201. Several cleaning brushes 204 are distributed in a ring array on the circumferential surface of the installation cylinder 203. The cleaning brushes 204 are made of high wear-resistant nylon filaments and are fixed on the installation cylinder 203 by a bristle implantation process. They can penetrate deep into the gaps of the grid rake to remove residual slag.

[0028] One end of the rotating rod 202 extends out of the rotating groove 201 and is welded with a rotating disk 205; the rotating disk 205 is a circular steel plate, and its outer periphery is connected to the power assembly 5.

[0029] Furthermore, the power assembly 5 includes a mounting base 501, which is bolted to the top of the support frame 3. A motor 502 is bolted to the top of the mounting base 501. The motor 502 is preferably a Y100L-2 three-phase asynchronous motor with waterproof function.

[0030] The output shaft of motor 502 is connected to a rotating shaft 503 via a coupling. The end of the rotating shaft 503 is provided with a second rotating disk 504. The second rotating disk 504 has the same structure as the first rotating disk 205. Both of them have a transmission groove 6 on their circumferential surface. The transmission groove 6 is an annular groove used to accommodate the belt 7.

[0031] Rotary disk 204 and rotary disk 1205 are connected by 2-3 belts 7. The belts 7 are preferably polyurethane synchronous belts to avoid slippage and ensure stable power transmission. The belts 7 are located inside the transmission groove 6 to prevent deviation.

[0032] In a further embodiment, the mounting frame 1 is provided with a cleaning component 8 for assisting in cleaning the sticky residue on the surface of the cleaning brush 204 and the rake.

[0033] Specifically, the cleaning component 8 includes a fixing rod 801, which is a hollow stainless steel rod body. It is fixed inside the mounting frame 1 by a bracket and is located on the bottom of the slag tray 9 near the cleaning tank 10.

[0034] The fixed rod 801 is connected to the water pump 802 on the side away from the rotating rod 202 by bolts and nuts. To increase the fixing effect, the water pump 802 is also fixedly connected to the slag plate 9 by bolts. The water pump 802 is preferably a centrifugal pump or a BSP water pump.

[0035] The inlet end of the water pump 802 is connected to a pumping pipe 803, which is connected to the clean water network of the sewage treatment plant, a high-pressure water tank, or water that has passed through the sewage screen 101; the outlet end of the water pump 802 is connected to a drain pipe 804.

[0036] The fixed rod 801 is hollow inside, with 5-20 interfaces evenly opened on one side, each interface connecting to a high-pressure nozzle 805; the other side is connected to a drain pipe 804. Both the high-pressure nozzle 805 and the drain pipe 804 are connected to the hollow inside of the fixed rod 801, forming a high-pressure water flow channel from the water pump 802 to the drain pipe 804, the hollow inside the fixed rod 801, and the high-pressure nozzle 805.

[0037] The high-pressure nozzle 805 is preferably a fan-shaped atomizing nozzle, which is tilted upwards and aimed at the contact area between the cleaning brush 204 and the rake. It can wash away the sticky residue attached to the cleaning brush 204, while also helping to remove stubborn impurities in the gaps of the rake, and can also wash the cleaning brush 204.

[0038] The top of the mounting bracket 1 is provided with an operation slot 4, which is a rectangular opening, making it convenient for staff to observe the operating status of the cleaning components and replace the cleaning brush 204.

[0039] During setup, the support frame 3 is fixed to the top of the sewage grid 101 of the rotary grid cleaner with bolts, the slag plate 9 is fixed so that the gap between its top surface and the bottom of the grid's rake is ≤2mm, and the cleaning trough 10 is aligned with the feed inlet of the garbage conveyor 102.

[0040] When in use, start the garbage conveyor 102, the sewage grid 101, the motor 502 and the water pump 802; When motor 502 starts, it can sequentially drive rotating disc 2 504, belt 7, rotating disc 1 205, rotating shaft 503, mounting cylinder 203 and cleaning brush 204 to rotate.

[0041] The rakes of the sewage screen 101 carry the slag in the water and move along the slag support plate 9. The slag in the sewage screen 101 moves to the cleaning trough 10 with the rakes. The slag falls through the cleaning trough 10 and finally falls to the garbage conveyor 102 and is sent to the next processing equipment. The next processing equipment is an existing device, such as a collection box. Then, the slag enters the cleaning component 2 area with the rakes. The cleaning brush 204 rotates to remove the residual slag on the surface and in the gaps of the rakes. The high-pressure nozzle 805 washes the cleaning brush and rakes to prevent sticky slag from adhering. The cleaned slag falls into the garbage conveyor 102 through the cleaning trough 10, and is then transported to the garbage treatment station by the garbage conveyor 102.
