Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a sedimentation tank with good mud discharge effect. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purification device that uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter from water.

[0003] The granular matter in the influent mixture of the sedimentation tank settles downward, and the dissolved matter flows out horizontally with the water flow. Since the sludge precipitated in the sedimentation tank is the biochemical sludge floating out of the biochemical pool, its sludge specific gravity is lighter and is not easy to settle compared to the physicochemical sludge. Therefore, there is floating mud in the effluent. However, the floating mud is cleaned by employees using a filter net. This method is relatively cumbersome and has certain safety hazards. Utility Model Content

[0008] As a further solution of the present invention, a guide rod is fixedly connected between the two fixed plates, and the guide rod passes through the first slider to enable the first slider to move horizontally.

[0009] As a further solution of the present invention, two aeration pipes are fixedly connected to the mud hopper, and one end of the two aeration pipes passes through the mud hopper and extends to the outside of the mud hopper.

[0010] As a further solution of the present invention, a mud discharge pipe for discharging sludge is fixedly connected to the bottom of the mud hopper.

[0011] As a further solution of the present invention, water outlet pipes are fixedly connected to both sides of the pool body, and the water outlet pipes are located on one side of the fender.

[0012] As a further solution of the present invention, the two guide rails are respectively located directly above the two fenders, and the scraper is between the two fenders and in contact with the fenders.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordinated use of the scraper and the waste box, the scraper moves along the guide rail through the second slider, and the scraper will scrape the floating mud above to gather the floating mud together. Then the scraper is taken out from the pool body, and the floating mud will be fished out through the waste box. At the same time, the water will be discharged through the second through hole at the bottom of the waste box, so as to facilitate the fishing of the floating mud, save time and improve efficiency.

[0015] 2. Through the setting of the aeration pipe, when the compressed air enters the mud hopper through the aeration pipe, the gas stirs the surroundings of the mud hopper, and the physical and chemical sludge and water inside the mud hopper are mixed, and rearranged and distributed on the inner wall of the tank body. When the compressed air is turned off, the physical and chemical sludge is separated from the water, and the sludge settles again. In this way, after each compressed air flushing, the sludge at the bottom of the mud hopper is distributed in a new position, eliminating the sludge from being deposited around the mud hopper, thereby facilitating the discharge of the sludge into the sedimentation tank.

The mud bucket 9 drives the scraper 6 to move along the guide rail 5 through the second slider 16 through the power component. The scraper 6 will scrape the floating sludge in the pool body 2. When the floating sludge is scraped to one side of the pool body 2, the floating sludge is concentrated together. Then the scraper 6 is pulled upward to move. The scraper 6 will drive the second slider 16 to move upward to disengage the second slider 16 from the guide rail 5. In the process of moving upward, the scraper 6 will drive the waste box 18 to move. The waste box 18 will pick up the concentrated items. At the same time, water will be discharged from the waste box 18 through the second through hole 19 at the bottom of the waste box 18, thereby facilitating the removal of the floating mud, saving time and improving efficiency.

[0023] The first slider 13 is connected to the second slider 13 by a threaded connection 14, and the second slider 13 is connected to the first slider 13 by a threaded connection 14. A second slider 16 is welded to a side of the first slider 13 by a threaded connection 14, and the second slider 16 is connected to the second slider 13 by a threaded connection 14. A motor is fixed to one side of the fixing plate 17 by a bolt, and one end of the motor output shaft passes through the fixing plate 17 and is fixed to the threaded rod 11. A guide rod 12 is fixed between the two fixing plates 17 by bolts, and the guide rod 12 passes through the first slider 13 to enable the first slider 13 to move horizontally. When the scraper 6 needs to move, the motor is started, and the motor drives the threaded rod 11 to rotate. The threaded rod 11 drives the first slider 13 to move horizontally along the guide rod 12 through the threaded engagement between the first slider 13 and the first slider 13 drives the second slider 16 to move along the guide rail 5 through the engagement of the block 15 and the slot 14.

[0024] In particular, two aeration pipes 4 are fixed in the mud hopper 9 by bolts, and one end of the two aeration pipes 4 passes through the mud hopper 9 and extends to the outside of the mud hopper 9. When the compressed air enters the mud hopper 9 through the aeration pipe 4, the gas stirs the surroundings of the mud hopper 9, and the physical and chemical sludge and water inside the mud hopper 9 are mixed and rearranged and distributed on the inner wall of the tank body 2. When the compressed air is turned off, the physical and chemical sludge is separated from the water, and the sludge settles again. In this way, after each compressed air flushing, the sludge at the bottom of the mud hopper 9 is completely distributed, and the sludge is prevented from being deposited around the mud hopper 9, thereby facilitating the discharge of the sludge into the sedimentation tank. The bottom of the mud hopper 9 is fixed with a mud discharge pipe 3 for discharging sludge by bolts, and the two sides of the tank body 2 are fixed with water outlet pipes 1 by bolts, and the water outlet pipe 1 is located on one side of the mud guard 7.

When the floating mud is scraped to one side of the tank body 2, the floating mud is removed. The scraper 6 then drives the second slider 16 to move upwards to disengage the second slider 16 from the guide rail 5. At the same time, the second slider 16 drives the card block 15 to move to disengage the card block 15 from the card slot 14. The scraper 6 drives the waste box 18 to move in the process of moving upwards. The waste box 18 picks up the collected items. At the same time, water is discharged from the waste box 18 through the second through hole 19 at the bottom of the waste box 18, thereby facilitating the removal of the floating mud, saving time and improving efficiency.
