Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filtration device. Background Technology

[0002] Wastewater treatment refers to the process of separating, transforming, or decomposing pollutants in wastewater through physical, chemical, and biological methods to meet discharge standards or achieve resource utilization. Wastewater treatment is a crucial link in protecting water resources, improving the ecological environment, and achieving sustainable development.

[0003] Wastewater treatment often employs filtration to remove impurities and improve water quality. However, wastewater often contains large particles that existing filtration devices cannot separate, causing these particles to accumulate on the filter plates and impair their normal filtration function. Furthermore, since the filter plates are located inside the housing, removing and replacing them is inconvenient. Therefore, a wastewater treatment filtration device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing filtration devices being unable to separate large objects in wastewater, causing these large objects to accumulate on the filter plate and affecting its normal filtration, and the filter plate being located inside the housing, making it inconvenient to remove and replace the filter plate. Therefore, this invention proposes a wastewater treatment filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater treatment filtration device includes a housing, an inlet pipe connected to the top of the housing, an outlet pipe fixedly connected to the bottom of the housing, a solenoid valve installed on the outlet pipe, a swaying plate inclinedly arranged inside the housing, a placement frame fixedly connected to one side of the housing, a collection basket placed in the placement frame, a swaying mechanism for separating large objects mixed in with the wastewater installed inside the housing, a first filter plate and a second filter plate installed inside the housing, a rectangular block fixedly connected to one side of the housing, and a fixing mechanism for fixing the first filter plate and the second filter plate on the rectangular block.

[0007] Preferably, the shaking mechanism includes a first drive motor fixedly installed on one side of the housing, a rotating rod rotatably mounted on the housing and fixedly connected to the output end of the first drive motor, a rotating plate fixedly connected to one end of the rotating rod, a connecting column fixedly connected to one side of the rotating plate, a first limiting block fixedly connected to one end of the connecting column, a connecting ring slidably connected between the rotating plate and the first limiting block, a connecting plate fixedly connected to one side of the connecting ring, a sliding block fixedly connected to the connecting plate, a limiting frame fixedly connected to the inner wall of the housing, the sliding block slidably connected to the limiting frame, and one side of the sliding block fixedly connected to the shaking plate.

[0008] Preferably, the connecting column is slidably connected to the inner diameter of the connecting ring, and the two sides of the box are fixedly connected to the housing, the inner wall of the housing being slidably connected to the rocking plate.

[0009] Preferably, an opening is provided on one side of the box body, a handle is fixedly connected to the top of the collection basket, a first round hole is provided on the shaking plate, a second round hole is provided on one side of both the collection basket and the box body, and a baffle is fixedly connected to the inner wall of the box body, the baffle being located above the shaking plate.

[0010] Preferably, the fixing mechanism includes a second drive motor fixedly installed on a rectangular block, a double-ended lead screw rotatably installed in the rectangular block and fixedly connected to the output end of the second drive motor, a movable nut provided on both ends of the double-ended lead screw, a clamping plate fixedly connected to each of the two movable nuts, and a second limiting block fixedly connected to one side of each clamping plate.

[0011] Preferably, the rectangular block has a rectangular opening, and a sealing plate is fixedly connected to one side of both the first and second filter plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When using this equipment, the shaking mechanism and sliding block drive the shaking plate to shake back and forth inside the housing, allowing large objects to fall into the collection basket through the opening. Some of the sewage attached to the surface of the large objects flows back into the tank through the second round hole, thereby achieving the purpose of separating large objects from the sewage and preventing large objects from accumulating on the filter plate and affecting the normal filtration of the filter plate.

[0014] 2. When using this equipment, the two filter plates can be clamped and fixed by the fixing mechanism.

[0028] An opening is provided on one side of the box body 1, a handle 20 is fixedly connected to the top of the collection basket 6, a first round hole is provided on the shaking plate 4, and a second round hole is provided on one side of both the collection basket 6 and the box body 1. A baffle 21 is fixedly connected to the inner wall of the box body 1, and the baffle 21 is located above the shaking plate 4.

[0029] The system provides power to the first drive motor 10 via an external device and controls its opening and closing. Wastewater is transported from the inlet pipe 2 into the tank 1. The wastewater falls through the first round hole on the shaking plate 4. Large objects in the wastewater fall onto the inclined shaking plate 4. The first drive motor 10 drives the rotating rod 11 to rotate. The rotating rod 11 drives the rotating plate 12 to rotate. The rotating plate 12 drives the connecting column 13 to rotate. The connecting column 13 drives the connecting ring 15 between the rotating plate 12 and the limiting block to move back and forth. The connecting ring 15 drives the connecting plate 16 to move back and forth. The connecting plate 16 drives the sliding block 17 to slide back and forth along the limiting frame 18. The sliding block 17 drives the shaking plate 4 to shake back and forth inside the housing 19, allowing large objects to fall into the collection basket 6 through the opening. Some wastewater adhering to the surface of the large objects flows back into the tank 1 through the second round hole. When a large number of large objects accumulate in the collection basket 6, the wastewater filtration is paused. The collection basket 6 is removed by the handle 20, replaced with a new collection basket 6, and the large objects are then processed.

[0030] During sliding, both sides of the rocking plate 4 are always inside the housing 19, and the rocking plate 4 is in close contact with the inner wall of the housing 19 to prevent large objects from falling into the housing 19.

[0031] Baffle 21 is used to block large objects and prevent them from falling onto the first filter plate 7 from the shaking mechanism.

[0032] Furthermore, the fixing mechanism includes a second drive motor 22 fixedly installed on the rectangular block 9. A double-ended lead screw 23 fixedly connected to the output end of the second drive motor 22 is rotatably installed in the rectangular block 9.

[0033] The rectangular block 9 has a rectangular opening. A sealing plate 25 is fixedly connected to one side of the first filter plate 7 and the second filter plate 8. The sealing plate 25 is located inside the rectangular opening. A handle is fixedly connected to one side of the sealing plate 25. A sliding frame 26 is fixedly connected to the inner wall of the box body 1. The two sides of the first filter plate 7 and the second filter plate 8 are slidably connected to the two sliding frames 26 respectively. The rectangular block 9 has a receiving cavity. The clamping plate 24 is slidably connected to the receiving cavity. A limiting groove 27 is opened on the sealing plate 25. The second limiting block is located in the limiting groove 27.

[0034] After the large objects are separated, the sewage is filtered through the first filter plate 7 and the second filter plate 8 and then discharged from the outlet pipe 3.

[0035] The second drive motor 22 is powered by an external device and its opening and closing are controlled. When the first filter plate 7 and the second filter plate 8 need to be replaced, the second drive motor 22 drives the double-ended lead screw 23 to rotate. The double-ended lead screw 23 drives the two moving nuts to move away from each other. The moving nuts drive the clamping plates 24 to move away from each other. The clamping plates 24 drive the second limiting block to move out of the limiting groove 27. The two filter plates can then be removed from the box 1 by pulling the sealing plate 25 with the handle. The first filter plate 7 and the second filter plate 8 are then replaced and reinserted into the sliding frame 26, and the second limiting block is used to limit them again.

[0036] Meanwhile, the specific models and specifications of the first drive motor 10 and the second drive motor 22 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0037] The working principle of this utility model:

[0038] Wastewater is transported into the tank 1 through the inlet pipe 2. The wastewater falls through the first round hole on the shaking plate 4. Large objects in the wastewater fall onto the tilted shaking plate 4. The first drive motor 10 drives the rotating rod 11 to rotate. The rotating rod 11 drives the rotating plate 12 to rotate. The rotating plate 12 drives the connecting column 13 to rotate. The connecting column 13 drives the connecting ring 15 between the rotating plate 12 and the limiting block to move back and forth. The connecting ring 15 drives the connecting plate 16 to move back and forth. The connecting plate 16 drives the sliding block 17 to slide back and forth along the limiting frame 18. The sliding block 17 drives the shaking plate 4 to shake back and forth in the shell 19, allowing large objects to fall into the collection basket 6 through the opening. Some of the wastewater attached to the surface of the large objects flows back into the tank 1 through the second round hole.

[0039] After the large objects are separated, the sewage is filtered through the first filter plate 7 and the second filter plate 8, and then the solenoid valve controls the water to be discharged from the outlet pipe 3.
