Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a sedimentation tank for wastewater treatment. Background Technology
[0002] Wastewater treatment is a crucial environmental protection and resource utilization task. Wastewater typically contains various pollutants, such as organic matter, heavy metals, pathogens, and nutrients. The purpose of wastewater treatment is to remove these pollutants so that they meet discharge standards or can be safely reused.
[0003] Sedimentation tanks are an important part of the wastewater treatment process. Their main function is to use gravity settling to allow solid particles and suspended solids in the wastewater to gradually settle to the bottom in a static environment, thereby achieving solid-liquid separation.
[0004] In the existing technology, during the wastewater sedimentation process, the sediment contains large impurities as it settles downwards. If these impurities are not filtered in time, they can clog the waste discharge pipes and prevent discharge, affecting the use of the sedimentation tank. At the same time, when the water separated by sedimentation is discharged, the impurities are easily mixed with each other by the flow of the drainage, resulting in a decrease in drainage accuracy. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] In view of the problems existing in the current sedimentation tank for wastewater treatment, this utility model is proposed.
[0007] Therefore, the purpose of this utility model is to provide a sedimentation tank for wastewater treatment, which solves the problem that "during the sedimentation process of wastewater, large impurities may be present in the sediment as it settles downwards. If these impurities are not filtered in time, they will block the waste discharge pipe and prevent discharge, affecting the use of the sedimentation tank. At the same time, when the water separated by sedimentation is discharged, impurities are easily mixed with each other by the flow of the drainage, resulting in a decrease in drainage accuracy."
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: including:
[0009] The main unit includes a box, on which an inlet pipe and an outlet pipe are fixedly connected respectively, and a first valve is fixedly connected to the outlet pipe;
[0010] The sedimentation unit includes a lower tank body, which is fixedly connected to the box body. A waste discharge pipe is fixedly connected to the side of the lower tank body away from the box body, and a second valve is fixedly connected to the waste discharge pipe. The inner wall of the box body near the lower tank body is concave, and a switching component for filtering impurities and blocking waste residue is provided on the box body.
[0011] In a preferred embodiment of the sedimentation tank for wastewater treatment described in this utility model, the switching assembly includes a filter plate and a partition plate. The filter plate and the partition plate are slidably connected to the housing. A rope is fixedly connected to both the filter plate and the partition plate, and the rope moves through the housing. A connecting block is fixedly connected to the side of the filter plate and the partition plate away from the rope. A support plate is fixedly connected to the side of the housing away from the outlet pipe, and an electric push rod is fixedly connected to the support plate. A vertical block is rotatably connected to the telescopic end of the electric push rod. Connecting rods are fixedly connected to both sides of the vertical block, and one of the connecting rods is connected to the corresponding connecting block.
[0012] As a preferred embodiment of the sedimentation tank for wastewater treatment described in this utility model, the inner walls of both sides of the tank are rotatably connected to a rotating rod, and the two arms of the rotating rod are fixedly connected to protrusions, with the two protrusions contacting the filter plate.
[0013] In a preferred embodiment of the sedimentation tank for wastewater treatment described in this utility model, multiple transmission plates are fixedly connected in a ring at the center of the arm of the rotating rod, and the multiple transmission plates are located on one side of the inlet pipe.
[0014] In a preferred embodiment of the sedimentation tank for wastewater treatment described in this utility model, a water pump is fixedly connected to the tank body, and a return pipe is fixedly connected to the output end of the water pump.
[0015] In a preferred embodiment of the sedimentation tank for wastewater treatment described in this utility model, the input end of the water pump is connected to the tank body, and the top end of the return pipe is connected to the tank body.
[0016] The beneficial effects of this utility model are:
[0017] 1. It can be connected to the connecting block via a connecting rod, so that the electric push rod can move the filter plate out of the box, and the rope can pull the partition back into the box by the movement of the filter plate. This makes it convenient for users to perform drainage and waste discharge operations during the cleaning of filtered impurities, thereby improving the efficiency of wastewater treatment. It is also beneficial to prevent the flow of precipitated impurities from mixing with water due to the flow of drainage. Conversely, the electric push rod can be reset, and the partition can be moved out of the box again to realize the filter plate switching in, thereby filtering and settling wastewater and improving the precision of wastewater treatment.
[0018] 2. The transmission plate can rotate under the impact of the wastewater flow, thereby driving the protrusions to continuously vibrate the filter plate. The vibration causes smaller impurities to fall downwards through the holes, while impurities in the blocked holes are pushed to one side, ensuring smooth filtration, reducing the energy consumption of the equipment, and the water in the tank is drawn out by the water pump and then subjected to secondary sedimentation through the return pipe, which is convenient and fast.

[0028] Reference Figure 1-3 This utility model provides a sedimentation tank for wastewater treatment, comprising:
[0029] The main unit 100 includes a box 101, on which an inlet pipe 102 and an outlet pipe 103 are fixedly connected, and a first valve is fixedly connected to the outlet pipe 103.
[0030] The sedimentation unit 200 includes a lower tank 201, which is fixedly connected to the box 101. A waste discharge pipe 202 is fixedly connected to the side of the lower tank 201 away from the box 101. A second valve is fixedly connected to the waste discharge pipe 202. The inner wall of the box 101 near the lower tank 201 is concave. A switching component 203 for filtering impurities and blocking waste residue is provided on the box 101.
[0031] The switching component 203 includes a filter plate 203a and a partition plate 203b. Both the filter plate 203a and the partition plate 203b are slidably connected to the housing 101. A rope 203c is fixedly connected to both the filter plate 203a and the partition plate 203b, and the rope 203c moves through the housing 101. A connecting block 203d is fixedly connected to the side of the filter plate 203a and the partition plate 203b away from the rope 203c. A support plate is fixedly connected to the side of the housing 101 away from the outlet pipe 103, and an electric push rod 203e is fixedly connected to the support plate. A vertical block 203f is rotatably connected to the telescopic end of the electric push rod 203e. Connecting rods 203g are fixedly connected to both sides of the vertical block 203f, and one of the connecting rods 203g is connected to the corresponding connecting block 203d. The connecting rod 203g is connected to the connecting block 203d, which allows the electric push rod 203e to move the filter plate 203a out of the housing 101. The movement of the filter plate 203a via the rope 203c moves the partition plate 203b into the housing 101, facilitating drainage and waste discharge during the cleaning of filtered impurities. Conversely, the electric push rod 203e is reset, and the partition plate 203b is moved out of the housing 101, allowing the filter plate 203a to switch in and filter and settle the wastewater. One end of the connecting rod 203g is smaller than the aperture of the connecting block 203d, allowing the connecting rod 203g to move within the connecting block 203d. A sealing rubber ring is fixedly connected to the point where the rope 203c passes through the housing 101, and the rope 203c moves within the sealing rubber ring.
[0032] Furthermore, the inner walls on both sides of the housing 101 are rotatably connected to a rotating rod 204. The two arms of the rotating rod 204 are fixedly connected to protrusions 205. The two protrusions 205 are in contact with the filter plate 203a. Through the contact between the protrusions 205 and the filter plate 203a, the filter plate 203a is vibrated, causing smaller impurities to fall downward through the holes. At the same time, the impurities in the blocked holes are pushed out to one side, ensuring the smoothness of filtration.
[0033] Furthermore, multiple transmission plates 206 are fixedly connected in a ring at the center of the arm of the rotating rod 204, and the multiple transmission plates 206 are located on one side of the water inlet pipe 102. The transmission plates 206 rotate under the impact of the wastewater flow, thereby driving the continuous vibration effect of the protrusion 205, reducing the energy consumption of the equipment.
[0034] Furthermore, a water pump 207 is fixedly connected to the housing 101, and a return pipe 208 is fixedly connected to the output end of the water pump 207. The water pump 207 draws water separated from the upper sedimentation layer, so that the water flows back to the filter plate 203a to achieve secondary filtration and sedimentation of the water.
[0035] Furthermore, the input end of the water pump 207 is connected to the housing 101, and the top end of the return pipe 208 is connected to the housing 101. Water is drawn from the housing 101 by the water pump 207, and then the water undergoes secondary sedimentation through the return pipe 208, which has an automated processing effect and is convenient and fast.
[0036] During use, by connecting the connecting rod 203g to the connecting block 203d, the electric push rod 203e can move the filter plate 203a out of the housing 101. The movement of the filter plate 203a via the rope 203c moves the partition 203b into the housing 101, facilitating drainage and waste discharge during the cleaning of filtered impurities. Conversely, the electric push rod 203e can be reset, and the partition 203b can be moved out of the housing 101, allowing the filter plate 203a to switch in and filter the wastewater for sedimentation. This helps to block the sedimentation water and prevent the sedimented impurities from mixing with the water due to the flow of drainage. It also has a preliminary filtration effect on the wastewater, improving the precision of wastewater treatment. When cleaning impurities on the filter plate 203a, chemical agents for wastewater treatment can be added into the housing 101. The subsequent inflow of wastewater mixes thoroughly with the chemical agents, achieving the effect of chemical wastewater treatment.
[0037] The transmission plate 206 can rotate under the impact of the wastewater flow, thereby driving the protrusion 205 to continuously vibrate the filter plate 203a. This vibration causes smaller impurities to fall downwards through the holes in the filter plate 203a, while simultaneously causing impurities in the blocked holes to be pushed to one side, ensuring smooth filtration, reducing the energy consumption of the equipment, and drawing water from the tank 101 through the water pump 207, and then allowing the water to undergo secondary sedimentation through the return pipe 208, which is convenient and quick.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
