Technical Field

[0001] The utility model relates to the technical field of sewage filtration, and specifically, to a switching type filtration device for sewage discharge. Background Technique

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage, mainly the water used in daily life, which contains more organic matter and is relatively easy to treat. Since there are sundries of different sizes in sewage, it is easy to block the sewage pipe, and a filtration device is needed to filter the sundries in the sewage.

[0003] After retrieval, in the prior art (publication number: CN218130378U), a filtration device for sewage is proposed, which states that "it includes a filter and a conversion pipe, and the conversion pipes are installed on the front and back of the filter; the air blowing pipes are installed on both sides of the front of the filter; the mounting plates are installed on both sides of the filter, and the adjustable filter box is installed inside the filter." However, the prior art cannot switch the filtration aperture. Since there are sundries of different sizes in different sewage, if the aperture is too large, small sundries will pass through the filtration holes, reducing the filtration effect. Therefore, it is very necessary to design a switching type filtration device for sewage discharge. Content of the Utility Model

[0004] The purpose of the utility model is to provide a switching type filtration device for sewage discharge, which solves the problem in the related technology that the filtration aperture cannot be switched during use, and there are sundries of different sizes in different sewage, which will reduce the filtration effect.

[0006] A switching type filtration device for sewage discharge includes a filter cylinder, a motor is screwed inside the filter cylinder, and a baffle is fixed to the output end of the motor. A filter plate is welded inside the filter cylinder, and the filter plate is in contact with the baffle. An activity groove is opened on the filter cylinder, and a sealing plate is inserted into the top of the activity groove. A scraping plate is inserted into the bottom of the activity groove, and connecting rods are welded on both sides of the top of the scraping plate. One end of the top of the connecting rod is welded and fixed to the bottom of the sealing plate. A connecting block is welded in the center of the top of the sealing plate, and handles are welded on both sides of the connecting block. Three first filtration openings are opened on the filter plate, and a second filtration opening is arranged between adjacent two first filtration openings.

[0007] Preferably, both the sealing plate and the scraping plate are arc-shaped and correspond to the contour radian of the filter cylinder, and a sealing gasket for enhancing the sealing property is arranged outside the sealing plate.

[0008] Preferably, the first filtering port is composed of a plurality of circular holes, the second filtering port is fan-shaped, and the baffle is in the shape of three blades.

[0009] Preferably, a pressing groove is formed in the top end face of the connecting block, a bracket is welded to the top outer wall of the filtering cylinder, and a threaded pressing rod is arranged on the bracket.

[0010] Preferably, the bottom end of the threaded pressing rod is inserted into the pressing groove. The outer wall of the top of the threaded pressing rod is provided with an external thread, and the threaded pressing rod is connected to the bracket through the thread. A wrench is welded to the top end of the threaded pressing rod.

[0011] Preferably, a butterfly valve body is arranged inside the filtering cylinder, and a handwheel is arranged on the top of the butterfly valve body.

[0012] Preferably, connecting heads are welded to both ends of the filtering cylinder, and docking grooves are formed around the outer wall of the connecting heads. Screw holes are formed in the outer wall of the docking grooves.

[0013] Preferably, first sealing rings are adhesively bonded to both ends of the filtering cylinder, second sealing rings are adhesively bonded to the connecting heads, reinforcing frames are welded to the top and bottom of the motor, and the other ends of the reinforcing frames are fixedly welded to the inner wall of the filtering cylinder.

[0014] The beneficial effects of the present utility model:

[0015] Debris in the sewage can be filtered through the filter plate. By driving the baffle to rotate through the motor, the first filtering port and the second filtering port can be respectively blocked, achieving the purpose of switching the filtering effect. This method is beneficial for filtering different sewage discharged in the sewage pipe, improving the sewage filtering effect. By pulling the handle, the sealing plate can be lifted. When the sealing plate rises, the scraping plate can be driven to move synchronously through the connecting rod. By moving the scraping plate upward, the debris filtered by the filter plate can be discharged, preventing the sewage pipe from being blocked by excessive debris.

[0016] By rotating the handwheel, the butterfly valve body can be rotated. The butterfly valve body can block the filtering cylinder to prevent water flow from passing through the filtering cylinder. By using the screw holes at the docking grooves, the connecting head can be docked with the sewage pipe using bolts. The first sealing ring and the second sealing ring can increase the connection tightness between the filtering cylinder and the sewage pipe. By turning the wrench, the threaded pressing rod moves downward, pressing the pressing groove, and the sealing plate can be pressed tightly on the movable groove to ensure the sealing effect.

The first filtering opening 11 is composed of a plurality of round holes in combination, and the second filtering opening 12 is fan-shaped. The baffle 3 is in the shape of three blades, so that when the motor 2 drives the baffle 3 to rotate, only the first filtering opening 11 or the second filtering opening 12 can be blocked, achieving the purpose of switching and adjusting the filtering effect. A pressing groove 13 is opened on the top end face of the connecting block 9. A bracket 14 is welded to the outer wall of the top of the filtering cylinder 1, and a threaded pressure rod 15 is arranged on the bracket 14. By pressing the pressing groove 13 with the threaded pressure rod 15, the sealing plate 6 can be pressed tightly on the activity slot 5 to ensure the sealing effect. The bottom end of the threaded pressure rod 15 is inserted and installed inside the pressing groove 13.
