[0034] Reference Figures 1 to 5 As shown, the utility model discloses a grille dirt remover, including a grille dirt remover body 100, a cleaning device 200 and a flushing device 300, wherein a transmission chain 140 is arranged on the grille dirt remover body 100, a mesh plate 150 is arranged on the transmission chain 140, and a plurality of filter holes are arranged on the mesh plate 150; the cleaning device 200 is provided with a cleaning roller 210 and a first rotary drive 220, the first rotary drive 220 and the cleaning roller 210 are transmission-connected, and the rotation direction of the cleaning roller 210 is opposite to the rotation direction of the transmission chain 140; the cleaning roller 210 is provided with a brush portion 211, and the brush portion 211 abuts against the surface of the mesh plate 150; the flushing device 300 is provided with a duckbill nozzle 310, the input end of the duckbill nozzle 310 is connected to the water pipe 320, and the output end of the duckbill nozzle 310 is perpendicular to the surface of the mesh plate 150.

[0035] Specifically, in the present embodiment, the screen cleaner includes a screen cleaner body 100, a cleaning device 200 and a flushing device 300; the lower part of the screen cleaner body is arranged in the sewage tank, and the upper part is exposed to the air; the screen cleaner body is provided with a transmission chain 140, and a plurality of mesh plates 150 are provided on the transmission chain 140. In the present embodiment, the mesh plates 150 are continuously arranged on the transmission chain 140 in a horizontal direction along the length direction of the transmission chain 140, and a plurality of mesh plates 150 are provided on the transmission chain 140. The mesh plates 150 are provided with a plurality of holes. When the transmission chain 140 rotates, it drives the mesh plates 150 to rotate, and the mesh plates 150 can continuously and automatically intercept and collect debris and garbage in the sewage tank; the sewage after discharge passes freely through the holes on the mesh plates 150. When the mesh plate 150 moves to one side of the grille cleaner body 100, most of the solid matter falls due to gravity, and the remaining debris and garbage are cleaned up by the cleaning device 200 by controlling the reverse movement of the cleaning roller 210; in the present embodiment, by providing a brush portion 211 on the cleaning roller 210, most of the solid garbage attached to the mesh plate 150 can be reliably removed. In the present embodiment, the cleaning roller 210 can be provided on the inner side of the transmission chain 140 or on the outer side of the transmission chain 140. When the cleaning roller 210 is provided on the inner side of the transmission chain 140, the brush portion 211 can remove garbage impurities in the holes on the mesh plate 150; when the cleaning roller 210 is provided on the outer side of the transmission chain 140, the brush portion 211 can remove garbage impurities in the holes on the mesh plate 150 and residual garbage on the outer surface of the mesh plate 150. The specific setting method can be set according to the specific usage scenario. In this embodiment, the cleaning device 200 and the transmission chain 140 have the same movement cycle. When the transmission chain 140 is working, the cleaning device 200 can rotate with the rotation of the transmission chain 140. In this embodiment, the transmission chain 140 and the cleaning device 200 are independently driven and controlled, with a high degree of automation, and the movement is relatively independent, which is convenient for inspection and maintenance. The flushing device 300 adopts an interval movement mode. By setting a timer, the surface of the mesh plate 150 is periodically flushed, which is not only energy-saving and environmentally friendly, but also can be flushed from the inside to the outside by the duckbill nozzle 310 of the flushing device 300. High pressure flushing can be performed from the inside to the outside to remove a small amount of attached garbage on the mesh plate 150. In this embodiment, the design of the duckbill nozzle 310 helps to prevent the backflow and backflow of sewage into the water pipe 320, and avoid blockage in the water pipe 320 due to sediment. Through the design of this mechanism, the sewage treatment efficiency is improved, and the frequency of manual maintenance and the cost of sewage treatment are reduced.

[0036] In some embodiments of the utility model, the grille dirt remover body 100 includes a frame assembly 110, a first sprocket 120, a second sprocket 130, a second rotary drive, and a screw press. The frame assembly 110 is provided with a discharge port 111, and the screw press is arranged at the discharge port 111; the first sprocket 120 and the second sprocket 130 are rotatably arranged at the upper and lower ends of the frame assembly 110, respectively, and the transmission chain 140 is respectively connected to the first sprocket 120 and the second sprocket 130; the output end of the second rotary drive is connected to the first sprocket 120. In this embodiment, the frame assembly 110 adopts an integrated structure for easy installation. The upper and lower ends of the frame assembly 110 are respectively rotatably provided with a first sprocket 120 and a second sprocket 130, and the transmission chain 140 is wound around the first sprocket 120 and the second sprocket 130. In this embodiment, the chain drive method can ensure the accuracy of the average transmission ratio and the reliability of the work, avoid elastic sliding and slipping, so that the grille decontamination machine performs well in transmitting high power and overload capacity. At the same time, the tensioning force required for the chain drive is small, and the pressure effect on the shaft is limited. In addition, the chain drive can work stably in harsh environments, which expands the scope of application of this embodiment. In this embodiment, a screw press is provided at the discharge port 111 of the frame assembly 110, and the screw press is mainly used to dehydrate and compress the garbage impurities intercepted by the grille decontamination machine body 100. The screw press is composed of a feed hopper, a pressing screw, a spiral tube, a slag discharge pipe and a drive device. The garbage impurities intercepted by the grille decontamination machine body 100 enter the spiral tube from the feed hopper and are squeezed and dehydrated under the action of the pressing screw. The water squeezed out of the material passes through the filter screen and is collected in the water receiving basin and discharged from the drain pipe. The material is compressed and discharged through the slag discharge pipe, thereby significantly reducing the weight and volume of garbage impurities. The efficiency of garbage collection and treatment is improved. In this embodiment, the screw press can be a 5T10T double screw press, a LYZ type screw press, etc.

[0037] In some embodiments of the present invention, the duckbill nozzle 310 includes a quick connector 311, an upper shell 312 and a lower shell 313, the upper shell 312 and the lower shell 313 are respectively connected to the quick connector 311, and a flat channel is formed between the upper shell 312 and the lower shell 313. Specifically, in this embodiment, the duckbill nozzle 310 is connected to the water pipe 320 through the quick connector 311, and the upper shell 312 and the lower shell 313 form a duckbill structure. Through the design of this mechanism, when the water flow in the water pipe 320 passes through the duckbill nozzle 310, the water flow will be squeezed and accelerated, thereby forming a fan-shaped liquid flow with high pressure, which can quickly and efficiently clean the surface of the mesh plate 150.

[0038] In some embodiments of the utility model, the upper shell 312 / lower shell 313 and the quick connector 311 are rotatably connected, and the lower shell 313 / lower shell 313 and the quick connector 311 are fixedly connected. In this embodiment, the duckbill nozzle 310 can adopt an integrated structure. Preferably, in this embodiment, one of the upper shell 312 and the lower shell 313 adopts a movable design structure. When stopping working, the upper shell 312 and the lower shell 313 abut against each other to close the flat channel. When working, under the reaction force of the water flow, the upper shell 312 and the lower shell 313 form an opening for water flow to pass through. The design of this structure helps to prevent the backflow and backflow of sewage into the water pipe 320, and avoid blockage in the water pipe 320 due to sediment.

[0039] In some embodiments of the utility model, the duckbill nozzle 310 is provided with elastic connecting parts 314 on both sides of the upper shell 312 and the lower shell 313. In this embodiment, the duckbill nozzle 310 can adjust the installation position so that under normal conditions, under the influence of gravity, the upper shell 312 and the lower shell 313 abut against each other. However, due to the need to partially flush the mesh plate 150, the installation position of the duckbill nozzle 310 needs to be rotated and adjusted. Therefore, in this embodiment, by providing a structure of elastic connecting parts 314 on both sides of the upper shell 312 and the lower shell 313, the duckbill nozzles can be kept in contact with each other under normal conditions. They can be mutually in principle in the working state. Through the design of this mechanism, the sealing effect is good.

[0040] In some embodiments of the utility model, a trash-blocking auxiliary fence 400 is also included. The trash-blocking auxiliary fence 400 is provided with a trash-blocking base 410. The trash-blocking base 410 is provided with a flexible baffle 420, and the flexible baffle 420 abuts against the mesh plate 150. In this embodiment, since the upper and lower ends of the transmission chain 140 are both circular, and in order to prevent the transmission chain 140 from being too close to the bottom of the sewage tank, causing the transmission chain 140 to be stuck, a partial gap is usually reserved between the transmission chain 140 and the bottom of the sewage tank. In this embodiment, by providing the trash-blocking auxiliary fence 400, some garbage impurities can be prevented from flowing out from the bottom of the transmission chain 140, and the garbage collection effect is improved by the design of this structure.

[0041] In some embodiments of the utility model, the brush portion 211 is made of nylon. Specifically, the cleaning device 200 includes a cleaning roller 210 and a first rotary drive 220, and the first rotary drive 220 is transmission-connected to the cleaning roller 210; in this embodiment, the first rotary drive 220 can be a servo motor and a reducer. A brush portion 211 is provided in the circumferential direction of the cleaning roller 210, and the brush portion 211 is made of nylon. The brush portion 211 made of nylon has excellent wear resistance, elasticity and tensile strength, and can maintain its shape and function for a long time in different use environments. The resilience of the nylon bristles ensures that the brush portion 211 can quickly return to its original state after use. In addition, the acid and alkali resistance and anti-fungal properties of the nylon bristles make it suitable for use in sewage treatment environments.

[0042] In some embodiments of the present invention, the mesh plate 150 is an L-shaped structure, and steps are formed between adjacent mesh plates 150. In this embodiment, by setting the mesh plate 150 in an L-shaped structure, a large amount of garbage impurities can be stored on the steps, thereby improving the processing efficiency of the present invention.

[0043] In some embodiments of the utility model, the flushing device 300 includes a water pump, and the output end of the water pump is connected to the water pipe 320. Specifically, in this embodiment, the flushing device 300 includes a duckbill nozzle 310, a water pipe 320 and a water pump, wherein the water pump can be arranged at the rear side of the grille dirt remover body 100, or in a water reservoir or water storage mechanism arranged beside the sewage tank, and the water pump can draw water from the source and perform high-pressure cleaning through the duckbill nozzle 310 through the water pipe 320.

[0044] In some embodiments of the present invention, a pressure gauge 321 is provided on the water pipe 320. By providing the pressure gauge 321, the state of the pressure in the water pipe 320 can be monitored in real time to avoid blockage and damage to the equipment.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
