Technical Field

[0001] The utility model relates to the field of grids, in particular to a grid for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. During the sewage treatment process, it is often found that foreign matter will block the pipes of sewage treatment equipment during operation, and there will be floating and suspended matter. In order to avoid this phenomenon, it is necessary to use a screen to separate the suspended solids or floating matter in the sewage before sewage treatment to reduce the processing load of other subsequent treatment facilities.

[0003] However, most of the gratings on the current market need to be moved manually during use. The gratings are made of welded steel bars and are heavy. Manually moving the gratings is time-consuming and labor-intensive, and workers' physical exertion during long working hours leads to reduced work efficiency.

[0004] Therefore, it is necessary to provide a sewage treatment screen to solve the above technical problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in Figure 1 This is a structural schematic diagram of a preferred embodiment of a sewage treatment grid provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the gear installation structure shown; Figure 3 for Figure 1The schematic diagram of the installation structure of the collection box shown is a screen for sewage treatment, comprising: a shell 1, a first chute 2 is opened on the top of the shell 1, and the number of the first chute 2 is two, the grille body 3 is slidably installed inside the two first chutes 2, and the tops of the two grille bodies 3 are fixedly installed with fixed blocks 4, the top of the shell 1 and above the first chute 2 is fixedly installed with a protective shell 5, the inner side wall of the protective shell 5 is rotatably installed with a gear 6 through a bearing, and the number of the gears 6 is two, a chain 11 is installed between the two gears 6, and the two fixed blocks 4 are fixedly installed with the chain 11, When the screen is in use, the two screen bodies 3 are tightly attached together, and the sewage passes through the gap between the two screen bodies 3, while impurities and other debris are blocked by the screen bodies 3. When a certain amount of debris is accumulated, the gear 6 rotates to drive the chain 11 to rotate. Since one of the two fixing blocks 4 is installed above the chain 11 and the other is installed below the chain 11, the two screen bodies 3 move to both ends inside the first chute 2, and the debris flows into the collection box 13 with the sewage. Then the gear 6 rotates in the opposite direction, causing the chain 11 to rotate in the opposite direction, and the two screen bodies 3 approach each other to continue filtering the sewage.

[0020] A motor 7 is fixedly installed on one side of the top of the protective shell 5. The keyway on the output shaft end of the motor 7 is connected to the first pulley 8. The keyway on the outer side of one of the gears 6 is connected to the second pulley 9. A transmission belt 10 is provided between the first pulley 8 and the second pulley 9. The operation of the motor 7 effectively drives the first pulley 8 to rotate. Due to the setting of the transmission belt 10, the second pulley 9 rotates, and the second pulley 9 drives the chain 11 to rotate. The forward and reverse rotation of the motor 7 drives the two grille bodies 3 to move closer or farther away.

[0021] A second chute 12 is provided on the other side of the top of the shell 1, and there are two second chutes 12. A collection box 13 is slidably installed between the two second chutes 12. A handle 15 is fixedly installed on one side of the outside of the collection box 13. A lifting ring 14 is fixedly installed on the top of the collection box 13, and there are two lifting rings 14. After the two grille bodies 3 move to both ends, impurities enter the interior of the collection box 13. After the moving impurities are collected inside the collection box 13, the collection box 13 can be easily lifted and removed by the handle 15, which is convenient for cleaning the impurities. If the impurities are large and heavy, it can be connected to the lifting equipment through the lifting ring 14, so that the collection box 13 can be conveniently removed by the lifting equipment.

[0022] The working principle of the sewage treatment screen provided by the utility model is as follows:

[0023] Step 1: When the grille is in use, the two grille bodies 3 are tightly attached together, and the sewage passes through the gap between the two grille bodies 3, while impurities and other debris are blocked by the grille bodies 3. When a certain amount of debris is accumulated, the motor 7 effectively drives the first pulley 8 to rotate. Due to the setting of the transmission belt 10, the second pulley 9 rotates, and the second pulley 9 drives the gear 6 to rotate. The rotation of the gear 6 drives the chain 11 to rotate. Since one of the two fixed blocks 4 is installed above the chain 11 and the other is installed below the chain 11, the two grille bodies 3 move to both ends inside the first chute 2, and the debris flows into the collection box 13 with the sewage. After that, the gear 6 rotates in the opposite direction, causing the chain 11 to rotate in the opposite direction, and the two grille bodies 3 approach each other, continue to filter the sewage, and the two grille bodies 3 are driven close or away by the forward and reverse rotation of the motor 7.

[0024] Step 2: After the two grille bodies 3 move to both ends, the impurities enter the interior of the collection box 13. After the moving impurities are collected inside the collection box 13, the collection box 13 can be easily lifted and removed through the handle 15 to facilitate cleaning of the impurities. If the impurities are large and heavy, the lifting ring 14 can be connected to the lifting equipment to facilitate the removal of the collection box 13 by the lifting equipment.

[0025] Compared with related technologies, the sewage treatment grid provided by the present invention has the following beneficial effects:

[0026] When the screen is in use, the two screen bodies 3 are tightly attached together, and the sewage passes through the gap between the two screen bodies 3, while impurities and other debris are blocked by the screen bodies 3. When a certain amount of debris is accumulated, the gear 6 rotates to drive the chain 11 to rotate. Since one of the two fixing blocks 4 is installed above the chain 11 and the other is installed below the chain 11, the two screen bodies 3 move to both ends inside the first chute 2, and the debris flows into the collection box 13 with the sewage. Then the gear 6 rotates in the opposite direction, causing the chain 11 to rotate in the opposite direction, and the two screen bodies 3 approach each other to continue filtering the sewage.
