Description

Technical Field

[0001] The utility model relates to the technical field of polluted water treatment, in particular to a sedimentation tank structure for polluted water treatment. Background Technique

[0002] Polluted water refers to the discharged water from life and production that has been polluted to a certain extent. In order to recycle water resources, sewage treatment is required. A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. It uses the natural sedimentation or coagulation sedimentation of water to remove suspended solids in water. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube countercurrent sedimentation tanks are mostly used at present.

[0003] The sediment deposited at the bottom of the sedimentation tank will adhere to the inner wall surface of the sedimentation tank. Long-term accumulation is easy to corrode the sedimentation tank and also easy to form lumps. At the same time, the accumulation of a large amount of sediment affects the working effect of the sedimentation tank and makes it easy to block when discharging sewage in the existing sedimentation tank. At the same time, the existing sedimentation tank needs to flush the sediment out through water flow when discharging sewage. When the sediment adheres firmly, a large amount of water is required for flushing, but this will generate new sewage. Therefore, a sedimentation tank structure for polluted water treatment is proposed according to the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sedimentation tank structure for polluted water treatment, so as to solve the problems that the long-term accumulation of sediment is easy to form lumps and adhere to the inner wall of the sedimentation tank, and the existing sedimentation tank needs to flush the sediment out through water flow when discharging sewage. When the sediment adheres firmly, a large amount of water is required for flushing, which will generate new sewage.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sedimentation tank structure for treating polluted water, comprising a box body, a sedimentation hopper, a placement rack, a liquid inlet pipe and a liquid outlet pipe.

At the lower end surface of the sedimentation hopper, there is fixedly connected a motor, and at the end of the output shaft of the motor, there is fixedly connected a rotating shaft. On the outer surface of the rotating shaft, there is fixedly connected a fixed sleeve. On both the left and right sides of the outer curved surface of the fixed sleeve, there are fixedly connected brackets. On the outer end surfaces of the brackets, there are successively provided a first groove and a second groove.

[0026] Please refer to Figure 1-5, the present utility model provides a technical solution:

[0027] A sedimentation tank structure for treating polluted water, comprising a box body 1, a sedimentation hopper 4, a placement rack 5, a liquid inlet pipe 6 and a liquid outlet pipe 7. Both the front and rear sides of the inner wall of the box body 1 are fixedly connected with baffles 2. The front and rear sides of the inner wall of the box body 1 are fixedly connected with a group of inclined pipes 3. The group of inclined pipes 3 is arranged on the front and rear sides of the baffle 2. The lower end surface of the sedimentation hopper 4 is fixedly connected with a motor 8. The end of the output shaft of the motor 8 is fixedly connected with a rotating shaft 10. The outer side of the rotating shaft 10 is fixedly connected with a fixed sleeve 11. Both the left and right sides of the outer curved surface of the fixed sleeve 11 are fixedly connected with brackets 12. The outer end surfaces of the brackets 12 are successively provided with a first groove 13 and a second groove 14. A first scraping plate 16 is slidably connected to the inner side of the first groove 13. A second scraping plate 17 is slidably connected to the inner side of the second groove 14. A first spring 15 is fixedly connected between the inner wall of the first groove 13 and the outer end surface of the first scraping plate 16. A second spring 27 is fixedly connected between the inner wall of the second groove 14 and the outer end surface of the second scraping plate 17. The outer sides of the brackets 12 are all fixedly connected with inserting plates 18. The inner walls of the inserting plates 18 are all fixedly connected with magnetic blocks 19. Inserting strips 20 are arranged inside the inserting plates 18. A frame 21 is fixedly connected between the outer end surfaces of the inserting strips 20. A collecting cover 22 is fixedly connected to the outer end surface of the frame 21. A pulling ring 24 is fixedly connected to the upper end surface of the frame 21, enabling the first scraping plate 16 and the second scraping plate 17 to clean the inner wall of the sedimentation hopper 4. The collecting cover 22 is driven by the rotating shaft 10 to collect the sediment, realizing the ability of the sedimentation tank to collect and clean the sediment without generating new sewage, solving the problem that the long-term accumulation of sediment is prone to caking and adhering to the inner wall of the sedimentation tank. Existing sedimentation tanks need to flush out the sediment through water flow. When the sediment adheres firmly, a large amount of water is required for flushing, which will generate new sewage, improving the practicability of the device; a sealing sleeve 9 is fixedly connected to the guide hole at the lower end surface of the sedimentation hopper 4. The inner wall of the sealing sleeve 9 is in fit with the end of the output shaft of the motor 8. The sealing ability of the sedimentation hopper 4 is improved by setting the sealing sleeve 9; both the left and right sides of the outer curved surface of the rotating shaft 10 are fixedly connected with support rods 28. The other ends of the support rods 28 are all rotatably connected with stirring blades 26. The blocky sediment can be broken up by setting the stirring blades 26; adsorption layers 23 are fixedly connected to both sides of the outer end surface of the collecting cover 22. The collecting cover 22 is made of fine mesh weaving. The collecting ability of the collecting cover 22 is improved by setting the adsorption layers 23; both the front and rear sides of the upper end surface of the inserting plate 18 are fixedly connected with arc-shaped conduction plates 25. The outer end surface of the arc-shaped conduction plate 25 is in the same plane as the inner wall of the slot of the inserting plate 18. The reset ability of the frame 21 and the collecting cover 22 is improved by setting the arc-shaped conduction plates 25.

[0028] Workflow: When it is necessary to use the sedimentation tank to sediment polluted water, connect the polluted water pipeline to the liquid inlet pipe 6, so that the polluted water enters between the baffles 2 through the liquid inlet pipe 6. The polluted water passing through the baffles 2 will enter the inclined tube group 3 due to the inclination and closure of the sediment hopper 4. Due to the inclined setting of the inclined tube group 3, the impurities in the water flow will fall through the inclined surface of the inclined tube group 3 and settle into the sediment hopper 4, while the sedimented water will flow out through the liquid outlet pipe 7. When it is necessary to clean the sediment in the sediment hopper 4, start the motor 8 through the controller. The output shaft end of the motor 8 drives the rotating shaft 10, the fixed sleeve 11, and the bracket 12 to rotate. The rotation of the bracket 12 drives the first scraper 16 and the second scraper 17 to scrape the sediment adhering to the inner wall of the sediment hopper 4 (the first spring 15 and the second spring 27 are provided to enable the first scraper 16 and the second scraper 17 to have a certain buffer space during scraping and cleaning). At the same time, the rotation of the rotating shaft 10 drives the support rod 28 to rotate. The movement of the support rod 28 causes the stirring blade 26 to rotate in the water. The rotation of the stirring blade 26 can break up the massive sediment. At the same time, the rotation of the bracket 12 drives the frame 21 and the collection cover 22 to rotate. The rotation of the collection cover 22 collects the sediment (the adsorption layer 23 is provided to improve the collection ability of the collection cover 22). When the collection is completed, stop the motor 8, hook the hook rod to the pull ring 24, and hook the frame 21 and the collection cover 22 out from between the baffles 2 through the pull ring 24. At this time, the sediment can be taken out. After cleaning the collection cover 22, reset the frame 21 and the collection cover 22 through the arc-shaped conduction plates 25 arranged on the front and back sides of the insertion plate 18 (the upper and lower positions of the frame 21 are limited to a certain extent by the adsorption of the magnetic block 19 on the insertion strip 20). Through the above operations, the sedimentation tank can collect and clean the sediment without generating new sewage.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
