[0035] Please refer to Figures 1 to 4 A sewage deslagging device, comprising a deslagging assembly, comprising:
[0036] Deslagging tank, the upper portion of the deslagging tank is provided with an opening, the left side wall of the deslagging tank is provided with a water inlet, the right side wall of the deslagging tank is provided with a water outlet, the bottom of the deslagging tank is provided with a deslagging assembly, the bottom of the deslagging tank is provided with two support columns, the lower portion of the support column is provided with a base, the bottom of the deslagging tank is provided with a second through hole, and a rubber sealing ring is arranged in the second through hole;
[0037] Deslagging cover, the bottom of the deslagging cover is provided with a limiting column;
[0038] A circular ring is connected to the outer wall of the slag removal tank near the opening, and a first through hole matched with the limiting column is arranged on the circular ring.
[0039] A rotating shaft is detachably connected to the slag removal cover through a fastening device, and the axial direction of the rotating shaft is the same as that of the slag removal tank.
[0040] A filter frame is connected to the rotating shaft at the upper part, a filter screen is arranged in the filter frame, grooves are arranged on the left and right sides of the filter frame, rubber sealing strips are embedded in the grooves, and a limiting groove is arranged at the bottom of the filter frame and communicates with the grooves.
[0041] A moving plate is located below the bottom outer wall of the slag removal tank and is movably connected to the supporting column in the vertical direction.
[0042] A driving mechanism is used to drive the moving plate to move.
[0043] A stirring shaft is rotatably connected to the moving plate, one end of the stirring shaft is located in the slag removal tank, the radius of the stirring shaft matches the second through hole, and the end of the stirring shaft located in the slag removal tank is provided with a scraper, the shape of the scraper and the stirring shaft matches the limiting groove.
[0044] A first driving motor is connected to the moving plate, and the first driving motor is in transmission connection with the stirring shaft.
[0045] In the assembled state of the slag removal cover and the slag removal tank, the filter frame is located between the water inlet and the water outlet, the stirring shaft and the scraper are located in the limiting groove, the upper edge of the scraper abuts against the rubber sealing strip, one end of the scraper contacts the inner wall of the slag removal tank, and the limiting column is located in the first through hole.
[0046] In the above embodiments, it should be noted that the residue discharging assembly can refer to patent No. CN218923940U. In the assembled state, sewage is poured from the water inlet, and after the sewage passes through the filter screen in the filter frame, the residue is retained on the filter screen, and the sewage is discharged from the water outlet on the other side. By providing a rubber sealing ring in the second through hole, it prevents the sewage from leaking out of the second through hole and ensures the movement of the stirring shaft. After the filtration is completed, the cylinder drives the piston rod to extend and retract, causing the limiting column to disengage from the first through hole, and the residue removal cover is removed. The filter screen of the filter frame is cleaned, and then the driving mechanism drives the stirring shaft to move upward in the vertical direction, and the first driving motor drives the stirring shaft to rotate, thereby causing the scraper to scrape the inner wall of the residue removal tank. The scraped residue falls to the bottom of the residue removal tank. The driving mechanism drives the stirring shaft to move downward, and the scraper scrapes the residue at the bottom of the residue removal tank. The scraped residue is discharged through the residue discharging pipe of the residue discharging assembly, and the residue at the bottom of the residue removal tank is discharged by the fan of the residue discharging assembly. When the residue discharging is completed, the driving mechanism drives the stirring shaft to rise, the limiting groove at the bottom of the residue removal cover of the filter frame is matched with the stirring shaft and the scraper, then the residue removal cover is rotated, the limiting column of the residue removal cover is coaxial with the first through hole, and then the driving mechanism drives the stirring shaft to move downward. The residue removal cover is sealed with the residue removal tank by pulling it with the hand, and then the limiting column enters the first through hole. Through the limiting of the limiting column and the cooperation of the limiting groove, the stirring shaft and the scraper, the filter frame can be stably positioned in the residue removal tank, thereby completing the assembly of the residue removal tank and the residue removal cover. Compared with the prior art, the inner wall of the tank body can be cleaned, the filtering efficiency is improved, and the labor cost is reduced.
[0047] As an optional embodiment, the fastening device includes a flange and a screw, and the rotating shaft is fixedly connected to the residue removal cover through the flange and the screw.
[0048] In the above embodiments, the flange is connected to the rotating shaft and located in the residue removal cover. The fourth through hole is provided on the flange, and a threaded hole matched with the fourth through hole is provided in the residue removal cover. The rotating shaft is fixed to the residue removal cover by the screw passing through the fourth through hole and the threaded hole in sequence. Through the above detachable connection mode, the filter frame can be easily detached from the lower part of the residue removal cover for replacement and maintenance of the filter screen.
[0049] As an optional embodiment, the driving mechanism includes a lead screw shaft and a second driving motor. The lead screw shaft is connected to the base, the axial direction of the lead screw shaft is parallel to the axial direction of the residue removal tank, the moving plate is slidably connected to the lead screw shaft and the supporting column respectively, and the second driving motor is in transmission connection with the lead screw shaft.
[0050] In the above embodiments, the second driving motor is turned on to rotate the lead screw shaft, thereby driving the moving plate to move and allowing the stirring shaft to move up and down in the residue removal tank, so that the scraper cooperates with the first driving motor to scrape the inner wall of the residue removal tank.
[0051] As an optional implementation, the width of the filter frame matches the inner wall radius of the slag removal tank, and the width of the filter frame is smaller than the inner wall radius of the slag removal cover.
[0052] In the above implementation, by matching the width of the filter frame with the inner wall radius of the slag removal tank, the sealing rubber strip can be better matched during assembly, so as to avoid sewage leakage from both sides of the filter frame, reduce the filtering effect, and the filter frame can be more easily disassembled from the inner wall of the slag removal cover during disassembly.
[0053] As an optional implementation, the top of the slag removal cover is provided with a handle.
[0054] In the above implementation, the handle can better lift the slag removal cover.
[0055] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent transformation, direct or indirect application in related technical fields using the content of the present application specification and drawings are also included in the patent protection range of the present application.
