[0002] As a grid decontamination equipment, the screen decontamination machine is used to separate dirt from liquid through the screen in sewage treatment. It is widely used in municipal sewage treatment projects and water treatment systems in industrial industries such as petrochemicals, light industry, chemical fiber, papermaking, pharmaceuticals, and leather.

[0003] Most of the existing screen decontamination equipment include a circulating screen belt, which is tilted in the canal. The circulating motion of the screen belt is used to remove impurities in the water and scrape them off at the top of the screen belt, thereby removing impurities in the canal.

[0004] With respect to the above-mentioned related technologies, when the existing grille pollution removal equipment is extended into the canal to perform pollution removal work, the grille belt has dense meshes, which easily blocks the normal flow of water, causing the water flow rate to decrease, and debris is easily accumulated at the bottom of the grille belt. In addition, some flexible debris in the water, such as plastic bags, aquatic plants, etc., are easily entangled on the grille, causing the grille belt to be blocked. Therefore, the existing grid storage equipment is prone to blockage during pollution removal. Utility Model Content

[0007] By adopting the above technical solution, a push plate structure is rotated and connected at the bottom of the dirt removal equipment, and the water flow generated by the rotation of the push plate structure is used to lift up the debris accumulated at the bottom of the dirt removal equipment, so as to effectively clean up the debris that is not easy to be scraped off the grille belt, thereby avoiding the grille belt from being blocked due to a decrease in water flow capacity due to long-term use.

[0008] The utility model is further configured that side through bins are provided on both sides of the shell, and side openings are provided at the bottom ends of the side through bins.

[0009] By adopting the above technical solution, the water flowing through the grille belt can directly flow out through the side opening without having to pass through the grille belt again, thereby effectively improving the flow efficiency of the water flow.

[0010] The utility model is further configured such that two ends of the grille belt are respectively connected to two rotating shaft structures with the same diameter, two grille belts with opposite movement directions are included between the two rotating shaft structures, and the side through bin is located between the two layers of grille belts.

[0011] By adopting the above technical solution, the grid belt between the two rotating shaft structures circulates in a conveyor belt shape, which can continuously and effectively remove debris in the canal.

[0012] The utility model is further configured such that the bottom end of the shell is provided with bottom openings at intervals along the length direction, and the shell is provided with multiple groups of brush rollers in contact with the grille belt between the bottom opening and the grille belt, and the rotating shafts of the brush rollers are connected to each other through transmission belts, and the rotating shaft of one of the brush rollers is connected to the rotating shaft of the cleaning roller through a transmission belt.

[0014] The utility model is further configured that the rotating shaft of the brush roller is parallel to the cleaning roller, and the rotating direction is the same as that of the cleaning roller.

[0015] By adopting the above technical solution, the rotating shaft of the cleaning roller is used to drive the multiple groups of brush rollers to rotate, so that the brushes on the brush rollers move in opposite directions relative to the grille belt.

[0016] The utility model is further configured such that the shell is fixedly connected with an arc-shaped baffle above the cleaning roller, and is fixedly connected with an inclined filter plate below the cleaning roller, the top end of the filter plate is close to the grille belt but not in contact with it, and the bottom end is close to the inner wall of the shell.

[0017] By adopting the above technical solution, the arc-shaped baffle can effectively prevent the debris in the water from being thrown out due to the centrifugal force under the high-speed rotation of the cleaning roller, and the inclined filter plate can allow the debris to roll down smoothly.

[0018] The utility model is further configured that both sides of the shell are fixedly connected with rubber edges.

[0019] By adopting the above technical solution, the rubber edge can effectively fill the gaps on both sides of the shell, preventing sewage from flowing through the two sides of the shell.

A driving motor for driving the grille belt 2 and the cleaning roller 6 is respectively provided on one side outside the shell 1. Specifically, the motor for driving the rotating shaft is a mature existing technology. The rotating shafts of the cleaning roller 6 and the push plate roller 11 are both parallel to the rotating shaft of the grille belt 2. The rotation direction of the rotating shaft of the grille belt 2 is the same as that of the push plate roller 11, but opposite to the rotation direction of the cleaning roller 6.

[0033] See also Figure 1-4 The shell 1 is fixedly connected with an arc-shaped baffle plate 7 above the cleaning roller 6, and is fixedly connected with an inclined filter plate 8 below the cleaning roller 6. The rotation speed of the cleaning roller 6 is much higher than the rotation speed of the rotating shaft of the grille belt 2. The top of the filter plate 8 is close to the grille belt 2 but does not contact it, and the bottom end is close to the inner wall of the shell 1. The arc-shaped baffle plate 7 can effectively prevent the debris in the water from being thrown out due to the centrifugal force under the high-speed rotation of the cleaning roller 6, and the inclined filter plate 8 can allow the debris to roll down smoothly.

[0034] See also Figure 1-3 , side passage bins 3 are provided on both sides of the shell 1, and side openings 4 are provided at the bottom ends of the side passage bins 3, so that the water flowing through the grille belt 2 can flow out directly through the side openings 4 without having to pass through the grille belt 2 again, effectively improving the flow efficiency of the water flow, and two rotating shaft structures with the same diameter are respectively connected to the two ends of the grille belt 2, and two grille belts 2 with opposite movement directions are included between the two rotating shaft structures, and the side passage bins 3 are located between the two layers of grille belts 2, and the grille belts 2 between the two rotating shaft structures circulate in a conveyor belt shape, which can continuously and effectively remove debris in the canal. Embodiment 2

[0035] An anti-clogging grid decontamination device, such as Figure 1-5As shown, on the basis of Example 1, the difference from Example 1 is that the bottom end of the shell 1 is provided with bottom openings 9 at intervals along the length direction, and the shell 1 is provided with multiple groups of brush rollers 10 in contact with the grille belt 2 between the bottom opening 9 and the grille belt 2, and the rotating shafts of the brush rollers 10 are connected to each other through a transmission belt, and the rotating shaft of one of the brush rollers 10 is connected to the rotating shaft of the cleaning roller 6 through a transmission belt. The brush roller 10 and the grille belt 2 rub against each other, and the brush on the brush roller 10 further removes small impurities on the grille belt 2, effectively avoiding the adhesion of small debris and causing the grille belt 2 to be blocked, the rotating shafts of the brush rollers 10 are all parallel to the cleaning roller 6, and the rotation direction is the same as that of the cleaning roller 6. Specifically, a total of three brush rollers 10 are provided, and the rotating shafts of the three brush rollers 10 are connected to each other through a transmission belt, and the rotating shaft of the cleaning roller 6 is used to drive the multiple groups of brush rollers 10 to rotate, so that the brush on the brush roller 10 and the grille belt 2 move in opposite directions relative to each other.

[0036] The working principle of the utility model is as follows: the shell 1 is placed in the canal, the bottom end of the shell 1 contacts the bottom wall of the canal, the rubber edges 5 on both sides of the shell 1 close the gap, and then the driving structure of the grille belt 2 and the cleaning roller 6 drives the two to rotate, and the debris in the water leaves the water surface under the drive of the grille belt 2. When it moves to the cleaning roller 6, the cleaning roller 6 and the grille belt 2 rotate in the opposite direction to knock down the debris on it, and the water contained in the debris passes through the filter plate 8, and the debris slides along the filter plate 8 to the top platform of the shell 1 under the blocking of the arc-shaped baffle plate 7 for cleaning and transportation. The multiple groups of brush rollers 10 driven synchronously by the cleaning roller 6 clean the small pieces of debris on the grille belt 2. After the small pieces of debris are cleaned off the grille belt 2, they will flow away with the water flow without causing blockage. The push plate roller 11 at the bottom of the grille belt 2 is driven by the grille belt 2 shaft to rotate, and can lift up the debris accumulated on the bottom of the water so that it can be fully transported upward by the grille belt 2, further avoiding blockage.
