Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a sewage grille system with a self-contained deodorizing cover. Background Art

[0002] Due to the complex sources of municipal sewage, it contains not only a large amount of large suspended solids but also organic matter. After the organic matter in the sewage is decomposed, volatile gases containing substances such as hydrogen sulfide, ammonia and organic sulfides will be produced. These volatile gases have a strong odor. Environmental protection requires that the sewage pretreatment structure before the biochemical pool of the sewage plant and the sludge treatment structure in the plant should be covered to collect the odor source.

[0003] At present, sewage treatment plants generally adopt the form of sealing around sewage treatment grilles, which has the problem of high moisture in winter, which will cause grille rust, motor leakage, and inconvenient grille maintenance for a long time. In addition, the belt conveyor equipped with the existing sewage treatment grille is open, which is not conducive to the collection of odor; at the same time, large particles of suspended matter are easy to fall on both sides of the belt conveyor, which not only affects the sanitation of the plant area but also increases the labor intensity of the operators. Utility Model Content

[0004] In order to overcome the defects in the prior art, the utility model provides a sewage grille system with a self-contained deodorizing cover. The utility model can effectively remove large suspended particles, seal the structure, and remove the odor in the sewage during the treatment process.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sewage grille system with a self-contained deodorizing cover comprises a grille for intercepting suspended matter and a belt conveyor for conveying the suspended matter; the grille is installed in a water inlet grille channel, a grille cover is installed on the water inlet side section of the grille exposed from the water inlet grille channel, the belt conveyor is connected to the outlet end of the grille, and a belt conveyor cover is provided on the belt conveyor.

[0007] Preferably, grooves are provided on both sides of the water inlet side section of the grille exposed from the water inlet grille channel, baffles extending outward are provided at the bottom of the grooves, both sides of the grille cover are snap-connected with the grooves, and the bottom of the grille cover rests on the baffles.

[0008] Preferably, the top of the grille is also provided with a bracket which can buckle the top of the grille cover.

[0009] Preferably, the belt conveyor cover is provided with an opening connected to the grille outlet.

[0010] Preferably, the groove has a width of 5 mm and a depth of 10 mm.

[0011] Preferably, the side of the grille is provided with a deodorizing air duct hole connected to the factory deodorizing system.

[0012] Preferably, a sealing rubber pad is laid at the gap between the grille and the water inlet grille channel.

[0013] Preferably, a movable door is installed on the side of the belt conveyor cover.

[0014] The advantages of the utility model are:

[0015] (1) The grille deodorization system designed by the utility model has a simple structure and greatly saves the deodorization cost. At the same time, only the water inlet section of the grille exposed to the air is sealed, avoiding the problems of motor leakage and equipment rusting caused by large water vapor in the isolation cover in winter when the grille is completely sealed.

[0016] (2) The utility model provides a grille cover to seal the grille section originally exposed to the air, and provides a belt conveyor cover to seal the belt conveyor, which can not only effectively remove large particles of suspended solids, but also seal the structure where it is located, eliminate the odor in the sewage during the treatment process, and ensure the cleanliness of the factory area.

[0017] (3) The utility model can further prevent the odor in the sewage from overflowing by completely sealing the water inlet grille channel by providing a sealing rubber pad; at the same time, the movable door is provided to facilitate the replacement of the belt or maintenance of the belt conveyor.

[0024] like Figure 1-4As shown, a sewage grille system with a self-contained deodorizing cover comprises a grille 1, a water inlet grille channel 2, a belt conveyor 3, a grille cover 4 and a belt conveyor cover 5; the grille 1 is installed in the water inlet grille channel 2, and the water inlet side section of the grille 1 exposed from the water inlet grille channel 2 is installed with a grille cover 4, a grille cover baffle 12 is provided at the bottom of the grille 1 and 10 cm away from the top of the water inlet grille channel 2, and a groove 11 with a width of 5 mm and a depth of 10 mm is provided on both sides of the grille 1 from the top to the grille cover baffle 12, and a grille cover bracket 6 is provided on the top of the grille 1. The grille cover 4 slides into the groove 11 from the top of the grille 1, and the bottom is supported by the grille cover baffle 12. The top of the grille cover 4 is interlocked with the grille cover bracket 6, so that the grille cover 4 can be fixed on the water inlet side of the grille 1, so as to prevent the water inlet side of the grille 1 from being exposed to the outdoors, causing the volatile gas in the sewage to volatilize into the air. And a deodorizing air duct hole 7 is reserved on the side of the grille cover 4 for connecting to the deodorizing system of the plant area.

[0025] Furthermore, the outlet of the grille 1 (i.e., the position where the suspended matter intercepted by the grille 1 moves out of the grille 1) is connected to the opening 51 on the upper part of the belt conveyor cover 5, and the large suspended matter intercepted by the grille 1 is sent to the screen slag bucket in the factory area through the belt conveyor 3. The belt conveyor cover 5 is provided around the belt conveyor 3, and the outlet of the belt conveyor 3 extends into the screen slag bucket in the factory area. A movable door 9 is opened on the side of the belt conveyor cover 5 to facilitate the replacement or maintenance of the belt conveyor 3.

[0026] Furthermore, the system includes a grid 1 for intercepting suspended matter and a belt conveyor 3 for conveying suspended matter; the grid 1 is installed in the water inlet grid channel 2, and a grid cover 4 is installed on the water inlet side section of the grid 1 exposed from the water inlet grid channel 2, the belt conveyor 3 is connected to the outlet end of the grid 1, and a belt conveyor cover 5 is provided on the belt conveyor 3.

[0027] After the grille 1 is installed on the water inlet grille channel 2, there are gaps between the water inlet side and both sides of the grille 1 and the water inlet grille channel 2. The water inlet grille channel 2 can be completely sealed by laying a sealing rubber pad 8 to further prevent odor from overflowing.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
