Description

A scum collecting device for sewage treatment

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a scum collecting device for sewage treatment.

Background Art

Sewage treatment refers to the process of purifying sewage to make it meet the water quality requirements for drainage into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, and catering. In the process of sewage treatment, the scum of sewage needs to be collected.

During sewage treatment, there is usually scum on the water surface. In some existing sewage treatment scum collection devices, the scum continuously enters the interior of the filter device with the water flow during scum collection. When the water flow carries the scum through the filter plate, the water will pass through the filter plate, and the scum will be blocked by the filter plate. When the scum accumulates too much, since there is no scum cleaning mechanism in the device and it does not leave the filter plate in time, it is easy to clog the filter screen inside the device, which will affect the efficiency of scum collection and cause the equipment to fail to work. It may cause the filter holes of the device to be clogged for a long time without being discovered by the staff, thereby interrupting the filtration and wasting too much time. It is also more troublesome to clean the filter plate later.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-6. The utility model provides a technical solution: a scum collection device for sewage treatment, including a filter box 1, which is in the shape of a Chinese character "凵". The left side of the filter box 1 is fixedly connected to a counterweight block 19, and the right side of the filter box 1 is fixedly connected to a collection box 2. The front and rear sides of the upper surface of the filter box 1 are provided with inclined surfaces inclined toward the inside of the filter box 1, and the inclined surfaces are slightly lower than the horizontal plane, so that water can flow into the inside of the filter box 1. The front and rear sides of the inside of the filter box 1 are fixedly connected to filter plates 6, and the left and right sides of the filter plate 6 are fixedly connected to the opposite sides of the collection box 2 and the counterweight block 19. The filter plate 6 is in an inclined state. When the water flows through the inclined surface of the upper surface of the filter box 1 and flows into the surface of the filter plate 6, the water will flow through the filter holes on the surface of the filter plate 6. The scum on the water surface will be blocked by the filter holes on the surface of the filter plate 6, and will remain on the surface of the filter plate 6. The scum remaining on the surface of the filter plate 6 will slide to the inclined side of the filter plate 6 because the filter plate 6 is an inclined surface. A bottom filter plate 15 is fixedly connected to the inside of the filter box 1. The bottom filter plate 15 is arranged in an inclined state inside the filter box 1. The bottom filter plate 15 is inclined from left to right. The bottom filter plate 15 is arranged at the junction of the lower ends of the two filter plates 6. The left and right sides of the bottom filter plate 15 are fixedly connected to the opposite sides of the collection box 2 and the counterweight block 19. The collection box 2 is provided with a slag storage bin placement groove 18 connected to the surface of the collection box 2, and a slag cleaning and collecting device is arranged inside the slag storage bin placement groove 18.

Furthermore, the scum cleaning and collecting device includes a scum storage bin 17, the surface of the scum storage bin 17 is slidably connected to the inside of the scum storage bin placement groove 18, a filter hole is arranged on the left side of the scum storage bin 17, and a filter hole connected to the scum storage bin placement groove 18 and the inside of the filter box 1 is also opened on the collection box 2. The filter hole allows water to flow into the inside of the filter box 1, and the scum remains in the inside of the scum storage bin 17. After the device collects scum for a certain period of time, the staff can take the scum storage bin 17 out of the inside of the scum storage bin placement groove 18, clean the scum inside the scum storage bin 17, and then remove the scum storage bin 17 through the scum storage bin 17. The part of the bin placement groove 18 that is connected to the surface of the collecting box 2 is put back into the interior of the slag bin placement groove 18, and the slag bin 17 is fixed to the surface of the collecting box 2 by screws. The baffle of the slag bin 17 can isolate water to prevent water from flowing into the interior of the slag bin 17. A slag discharge port 16 that is connected to the interior of the slag bin placement groove 18 is opened on the left side of the collecting box 2. The lower surface of the slag discharge port 16 is flush with the upper surface of the right side of the bottom filter plate 15, so that the floating slag slides into the interior of the slag discharge port 16 through the surface of the bottom filter plate 15, and slides into the interior of the slag bin placement groove 18 through the slag discharge port 16, and then slides into the interior of the slag bin 17.

Furthermore, the upper surfaces of the collecting box 2 and the counterweight block 19 are fixedly connected to the motor support block 5, the upper surface of the motor support block 5 is fixedly connected to the motor 3, the output end of the motor 3 is fixedly connected to the rotating arm 4, the side of the rotating arm 4 away from the motor 3 is rotatably connected to the driven arm 7, and one side of the driven arm 7 is rotatably connected to the scraper telescopic arm 9.

Furthermore, two identical T-shaped slide grooves 12 are provided on one side of the scraper telescopic arm 9 close to the collecting box 2 and the counterweight block 19. The shape of the T-shaped slide groove 12 is T-shaped. A T-shaped slide bar 8 is fixedly connected to one side of the collecting box 2 close to the driven arm 7. The shape of the T-shaped slide bar 8 is also T-shaped. The surface of the T-shaped slide bar 8 is slidably connected to the inside of the T-shaped slide groove 12. The T-shaped slide bar 8 and the T-shaped slide groove 12 play a limiting role on the scraper telescopic arm 9.

Furthermore, telescopic grooves 13 are provided on both the front and rear sides of the scraper telescopic arm 9. The two telescopic grooves 13 are formed on both sides of the scraper telescopic arm 9 with the center of the scraper telescopic arm 9 as the midpoint. The telescopic grooves 13 extend to the outside of the scraper telescopic arm 9. The inside of the telescopic grooves 13 is slidably connected with a telescopic arm 10. The telescopic arm 10 extends to the outside of the scraper telescopic arm 9 through the telescopic grooves 13. A slope is provided on one side of the telescopic arm 10 extending to the outside of the scraper telescopic arm 9. Springs 14 are fixedly connected to the opposite sides of the two telescopic arms 10. One end of the spring 14 away from the telescopic arm 10 is fixedly connected to the inner wall of the telescopic groove 13. The spring 14 can be compressed and reset by squeezing the telescopic arm 10.

Furthermore, the telescopic arm 10 extends to the opposite side of the side of the scraper telescopic arm 9 outside and is fixedly connected with a scraper 11, and the lower surface of the scraper 11 is slidably connected to the surface of the filter plate 6. When the staff turns on the motor 3, the output end of the motor 3 will drive the rotating arm 4 to rotate. When the rotating arm 4 rotates, the rotating arm 4 drives the driven arm 7 to move. When the driven arm 7 moves, the driven arm 7 will drive the scraper telescopic arm 9 to move. Because the T-shaped slide bar 8 restricts the T-shaped slide groove 12, the scraper telescopic arm 9 can only slide up and down on the opposite side of the collection box 2 and the counterweight block 19. The telescopic arm 10 uses the spring 14 to make one side of the telescopic arm 10 always keep in contact with the surface of the filter plate 6 when the scraper telescopic arm 9 moves up and down, so that the surface of the scraper 11 keeps in contact with the surface of the filter plate 6, thereby scraping the scum stuck on the surface of the filter plate 6 and making it slide downward, reducing the accumulation of scum on the surface of the filter plate 6, thereby clogging the filter holes.

Furthermore, floating blocks 20 are provided on opposite sides of the collecting box 2 and the counterweight block 19 , and the floating blocks 20 enable the device to always float on the water surface, so that the upper surface of the filter box 1 is always slightly lower than the horizontal plane, so that the water flow can flow into the interior of the filter box 1 .

Furthermore, a drain pump 21 is fixedly installed on the front side of the filter box 1. The input end of the drain pump 21 passes through the surface of the filter box 1 and extends to the interior of the filter box 1. The drain pump 21 is an existing structure and will not be elaborated on here. The drain pump 21 serves to drain the interior of the filter box 1.

Working principle: The scum collecting device for sewage treatment is placed in a sewage pool by a staff member when in use. The device floats on the water surface through the floating block 20. At this time, the upper surface of the filter box 1 is slightly lower than the water surface. The water flow will flow into the surface of the filter plate 6 through the upper surface of the filter box 1, and the scum on the water surface will be blocked by the filter holes on the surface of the filter plate 6, thereby remaining on the surface of the filter plate 6. The water will flow into the interior of the filter box 1 through the filter holes on the surface of the filter plate 6. The scum remaining on the surface of the filter plate 6 will slide to the inclined side of the filter plate 6 because the filter plate 6 is an inclined surface. When the scum slides into the surface of the bottom filter plate 15, the excess water will flow into the interior of the filter box 1 through the filter holes on the surface of the bottom filter plate 15. When the staff turns on the motor 3, the motor 3 will drive the rotating arm 4 to perform a circular motion. At this time, the rotating arm 4 rotates. The arm 4 will drive the driven arm 7 to move, and the driven arm 7 will drive the scraper telescopic arm 9 to move. Because the scraper telescopic arm 9 is limited by the T-shaped slide bar 8 through the T-shaped slide groove 12, the scraper telescopic arm 9 can only slide up and down under the guidance of the T-shaped slide bar 8. The telescopic arm 10 will be tightly attached to the surface of the filter plate 6 due to the spring 14 provided inside the telescopic groove 13, and the scraper 11 will be attached to the surface of the filter plate 6, so that the scraper 11 scrapes the scum stuck to the surface of the filter plate 6 and makes it slide downward. When the scum all falls onto the surface of the bottom filter plate 15, the scum will slide into the inside of the slag discharge port 16 due to the inclined surface of the bottom filter plate 15, so that the scum falls into the inside of the slag storage bin 17 for storage. The staff only needs to open the slag storage bin 17 regularly for cleaning.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
