Description

Technical Field

[0001] This utility model relates to the technical field of sewage filtration devices, specifically a sewage treatment device for water supply. Background Technology

[0002] Wastewater treatment equipment is an important component of water resource recycling and treatment systems. Its core function is to effectively remove impurities from wastewater to ensure that the water quality meets discharge or reuse standards. Wastewater contains a variety of impurities, among which gravel and debris are common and difficult to treat. These gravel and debris are not only large in size but also irregular in shape, easily clogging or blocking the filter mesh during the filtration process, thus affecting the filtration effect and the normal operation of the equipment.

[0003] A Chinese patent (publication number: CN216472530U) discloses a wastewater treatment device for water bureaus, including a tank, a limiting device, and auxiliary devices. However, this device uses a scraper for cleaning. The scraper moves across the filter screen as the equipment operates, removing impurities. However, when gravel falls into the tank with the wastewater, it easily gets stuck in the filter screen's mesh. This cleaning method is ineffective when dealing with gravel or debris stuck or clogging the filter screen, as the scraper often cannot penetrate deep enough to remove already stuck debris, requiring manual cleaning. This not only increases operational difficulty but also reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a wastewater treatment device for water supply, which solves the problem of difficult-to-clean gravel and debris clogging the filter mesh by using a top-out part and an L-shaped plate to push out gravel and debris inside the mesh.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a sewage treatment device for water supply, including a box body, a filter chamber inside the box body, a filter screen inside the filter chamber, two sliding holes on the box body, an L-shaped plate slidingly fitted in each of the two sliding holes, a top part at the bottom of the two L-shaped plates, and two connecting rods on the top part. A row of horizontal bars is connected to the two connecting rods, and a top rod is connected to each of the horizontal bars. The top of the top rod has a conical part.

[0007] Furthermore, the filter screen has perforations, and the tapered part fits into the perforations.

[0008] Furthermore, a U-shaped plate is installed on the box body, with through holes on the U-shaped plate, and a rotating shaft is also included. The two ends of the rotating shaft are fitted into the through holes, and a half-tooth gear is sleeved on the rotating shaft.

[0009] Furthermore, a rack is provided on the L-shaped plate, which meshes with a half-tooth gear.

[0010] Furthermore, a stop is installed on the outer surface of the L-shaped plate, and the stop is located at the top of the box.

[0011] Furthermore, an electric push rod is installed on the box, and a scraper is connected to the output end of the electric push rod. A collection box is also installed on the box.

[0012] This utility model has the following beneficial effects:

[0013] This utility model uses a top-out part and an L-shaped plate to push out the gravel and debris inside the mesh, so that the gravel and debris inside the filter mesh can be effectively pushed out, avoiding the defect of traditional scraper cleaning method that cannot penetrate into the filter mesh, thereby improving cleaning efficiency and reducing downtime caused by filter clogging, thus improving the overall operating efficiency of the equipment.

[0014] This invention uses a rack and pinion mechanism to circulate the ejector section. The rotation of the pinion drives the ejector section to intermittently eject gravel from the mesh, ensuring uninterrupted filtration during the use of the ejector section. This optimizes the cleaning cycle and ensures that gravel is cleaned in a timely manner when it accumulates to a certain level, preventing the filter from becoming clogged.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a wastewater treatment device for water supply, including a housing 1 and a rotating shaft 6. An inlet pipe is installed on the housing 1, with its end located between the top wall of the filter chamber 101 and the filter screen 2. An outlet pipe is installed at the bottom of the housing 1. An electric push rod 102 is installed on the housing 1, and a scraper 103 is connected to the output end of the electric push rod 102. When cleaning debris such as gravel from the filter screen 2, the electric push rod 102 is activated to drive the scraper 103 along the filter screen. 2. The upward-moving mechanism pushes the debris on the filter screen 2 into the collection box 104. The collection box 104 is installed on the box body 1, and a discharge port is opened on the back of the box body 1. The collection box 104 is detachably installed in the discharge port. After the collection box 104 has collected the gravel, it is disassembled and cleaned. A filter chamber 101 is opened inside the box body 1, and a filter screen 2 is installed inside the filter chamber 101. The filter screen 2 has mesh holes 201. The conical part 404 fits into the mesh holes 201. A sliding hole is opened on the box body 1. 105. There are two sliding holes 105, and L-shaped plates 3 are slidably fitted inside each of the two sliding holes 105. A push-out part 4 is provided at the bottom of each of the two L-shaped plates 3. The push-out part 4 has two connecting rods 401. A row of horizontal bars 402 is connected to each of the two connecting rods 401. A top rod 403 is connected to each of the horizontal bars 402. A tapered part 404 is provided at the top of the top rod 403. During wastewater filtration, wastewater enters the filter chamber 101 through the inlet pipe. At this time, the sewage is filtered through the filter screen 2. When gravel gets stuck inside the mesh 201, the L-shaped plate 3 is lifted and moves to the top along the sliding hole 105. This moves the connecting rod 401, causing the crossbar 402 to move the top rod 403 to the top. This causes the conical part 404 to enter the mesh 201 and push out the gravel that is stuck inside. Then, the electric push rod 102 is activated to push the scraper 103 to push the gravel on the filter screen 2 into the collection box 104 for collection.

[0023] A U-shaped plate 5 is installed on the housing 1, and a through hole is opened on the U-shaped plate 5. A drive source is externally connected to the rotating shaft 6, and both ends of the rotating shaft 6 are fitted into the through hole. A half-tooth gear 7 is sleeved on the rotating shaft 6. A rack 301 is provided on the L-shaped plate 3, and the rack 301 meshes with the half-tooth gear 7. A stop 8 is installed on the outer surface of the L-shaped plate 3. The stop 8 limits the distance that the ejector part 4 moves to the bottom when the water flow pushes it. The stop 8 is located at the top of the housing 1. When the gravel is ejected, the drive source drives the rotating shaft 6 to rotate, which in turn drives the half-tooth gear 7 to rotate. The half-tooth gear 7 is half-toothed, so when the teeth on the half-tooth gear 7 mesh with the rack 301, it can drive the L-shaped plate 3 to move to the top, bringing up the ejector part 4 to eject the gravel. Then the rack 301 meets the toothless part, and at this time it is pushed by the water flow to move the ejector part 4 to the bottom until the stop block 8 contacts the top surface of the box 1, so that the push rod 403 moves out of the mesh 201. During the continuous rotation of the half-tooth gear 7, it can drive the ejector part 4 to intermittently eject the gravel in the mesh 201, so that the filtration of the filter screen 2 will not be interrupted during the use of the ejector part 4.
