Description

Technical Field

[0001] This utility model relates to the field of wastewater purification tank technology, and in particular to a wastewater purification tank with a flow guiding structure. Background Technology

[0002] Wastewater purification tanks are facilities used to treat sewage, achieving effective purification and resource utilization of wastewater. They effectively remove pollutants from wastewater, reducing pollution to water bodies, soil, and the atmosphere, playing a vital role in environmental protection and water resource recycling. After the wastewater has been purified and filtered, flow-guiding structures (such as guide plates, guide channels, and buffer plates) are typically installed inside the wastewater purification tank to slow down the flow rate of the sewage within the sedimentation tank, prolonging the residence time of the sewage and improving wastewater treatment efficiency.

[0003] During use, wastewater containing a large amount of large suspended particles tends to accumulate in the small holes of the porous flow plate. Over time, these particles can clog the orifices, preventing wastewater from flowing through properly. This results in uneven flow velocity distribution, with some areas experiencing excessively fast flow and others stagnant flow. Consequently, the contact time and area between the wastewater and the treatment medium (such as microorganisms and chemical agents) are reduced, lowering wastewater treatment efficiency and affecting the treatment effect.

[0004] Therefore, how to design a flow guiding structure that facilitates the cleaning of impurities attached to the orifices of the flow buffer plate is a technical problem that engineers need to solve. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater purification tank with a flow guiding structure, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater purification tank with a flow guiding structure, characterized in that it comprises:

[0007] Purification and cleaning agencies;

[0008] The purification mechanism includes a filter box and a sedimentation box. The sedimentation box is equipped with a flow-slowing plate, the filter box is equipped with a connecting pipe, one end of which is located inside the sedimentation box. The filter box is equipped with a water inlet pipe, and the flow-slowing plate is equipped with several flow-slowing holes.

[0009] The cleaning mechanism includes a circular base plate, a cleaning scraper for cleaning impurities adhering to the inside of the slow-flow orifice, and an adjusting arc plate for adjusting the diameter of the cleaning scraper.

[0010] Preferably, the bottom of the circular base plate is provided with an elastic arc plate, one end of the elastic arc plate is provided with a cleaning arc plate, one end of the cleaning arc plate is provided with a limiting arc plate, the cleaning arc plate is provided with a limiting groove that matches the shape of the limiting arc plate, the limiting arc plate is slidably sleeved in the limiting groove, and one end of the cleaning arc plate and one end of the limiting arc plate are both provided with a cleaning scraper.

[0011] Preferably, the inner wall of the cleaning arc plate is provided with an elastic push plate, the elastic push plate is disposed between two cleaning arc plates, the outer wall of the elastic push plate is provided with an adjusting push plate, one end of the adjusting push plate is provided with an adjusting circular plate, and the inner wall of the circular base plate is provided with a limit block.

[0012] Preferably, the outer wall of the adjusting circular plate is provided with an adjusting arc plate, and the inner wall of the adjusting arc plate is provided with a limiting slot that matches the shape of the limiting block, and the limiting block is fixedly sleeved in the limiting slot.

[0013] Preferably, one end of the adjusting arc plate is provided with a pressing push plate, one end of the pressing arc plate is connected to the bottom of the adjusting push plate, and the other end of the adjusting arc plate is connected to the outer wall of the adjusting circular plate, and the two are distributed in a linear array on the outer wall of the adjusting circular plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this example, by setting up a cleaning mechanism, not only can impurities attached to the inner wall of the flow-slowing holes be cleaned, but also flow-slowing holes of different sizes can be cleaned. On the one hand, when it is necessary to clean the flow-slowing holes in the flow-slowing plate, the upper and lower cleaning mechanism is driven to move up and down inside the flow-slowing holes under the impact of water flow, thereby cleaning the impurities attached to the inner wall of the flow-slowing holes and avoiding blockage of the flow-slowing holes, which would lead to uneven distribution of wastewater flow velocity and affect wastewater treatment efficiency. On the other hand, when dealing with flow-slowing holes of different sizes, the cleaning mechanism can be adjusted to clean flow-slowing holes of different sizes, thereby improving the practicality of the cleaning mechanism.

[0041] Specifically, one end of the adjusting arc plate 210 is provided with a pressing push plate 213, which is connected to the bottom of the pressing push plate 213 at one end of the adjusting arc plate 210.

[0044] Example 1

[0045] In this embodiment, to solve the problem of uneven wastewater flow velocity caused by blockage of the slow-flow holes 106 inside the slow-flow plate 103, the technical solution of this embodiment is as follows, for reference. Figures 1 to 6The elastic arc plate 202 is S-shaped and has a certain degree of elasticity. It is installed on the circular base plate 201 and arranged in a linear array. The cleaning arc plate 203 has an arc-shaped curved surface structure and is arranged in a linear array within the flow-slowing holes 106, with the plates staggered. The cleaning scraper 206 has an arc-shaped elastic curved surface structure, and its outer wall is slidably connected to the inner wall of the flow-slowing holes 106. The float plate 215 is made of plastic and has a certain degree of buoyancy. (The last sentence appears to be incomplete and possibly refers to a separate process: "as wastewater flows from the filter box 101...") When the wastewater enters the sedimentation tank 102, it flows onto the slow-flow plate 103. At the same time, as the wastewater impacts the float plate 215, it cleans the impurities attached to the inner wall of the slow-flow hole 106. Under the action of the elastic arc plate 202, the inner wall of the cleaning arc plate 203 comes into contact with the inner wall of the cleaning scraper 206, and the cleaning scraper 206 comes into contact with the inner wall of the slow-flow hole 106. Then, under the action of the float plate 215, the cleaning scraper 206 is scraped and cleaned to avoid the slow-flow hole 106 from being blocked, which would cause uneven distribution of wastewater flow velocity and affect the wastewater treatment efficiency.

[0046] It should be noted that the limiting baffle 216 is an arc-shaped elastic curved surface structure. The limiting baffle 216 is set at the bottom of the circular base plate 201 and is distributed in a linear array. During use, it can restrict the position of the cleaning mechanism 2, thus affecting the cleaning effect of the cleaning mechanism 2 on the slow flow hole 106.

[0047] Example 2

[0048] In this embodiment, to solve the problem of inconvenient cleaning of the slow-flow holes 106 of different sizes, the technical solution of this embodiment is as follows, for reference. Figures 1 to 6 The elastic push plate 207 is an arc-shaped elastic curved surface structure, with both ends of the elastic push plate 207 positioned between the cleaning arc plates 203. The adjusting push plate 208 is an arc-shaped curved surface structure, positioned on the bottom plate of the adjusting circular plate 209 and arranged in a linear array. The adjusting arc plate 210 is an arc-shaped elastic curved surface mechanism, arranged in a linear array on the outer wall of the adjusting circular plate 209. The pressing push plate 213 is an arc-shaped elastic curved surface structure. By pressing the pressing push plate 213, the adjusting arc plate 210 is moved inward, causing the limiting block 212 to separate from the limiting slot 211. Then, by adjusting the position of the adjusting circular plate 209, the elastic push plate 207 is deformed under the action of the adjusting push plate 208, thereby pushing the cleaning arc plate 203 to open outward, adjusting the diameter between the cleaning scrapers 206, and thus cleaning the slow-flow holes 106 of different sizes.

[0049] It should be noted that the limiting block 212 is set on the inner wall of the circular base plate 201, and the shape of the limiting groove 211 is adapted to the shape of the limiting block 212. The limiting groove 211 is linearly arrayed in the adjusting arc plate 210. By fixing the limiting block 212 in the limiting groove 211 in the adjusting arc plate 210, the position of the cleaning arc plate 203 can be restricted to prevent the cleaning arc plate 203 from sliding during the cleaning process, so as to clean the slow flow holes 106 of different sizes.

[0050] As a further limitation of this technical solution, the shape of the limiting groove 204 is adapted to the shape of the limiting arc plate 205. The limiting arc plate 205 is slidably sleeved in the limiting groove 204. When adjusting the diameter between the cleaning arc plates 203, the cleaning arc plates 203 are positioned and slid. At the same time, they cooperate with the cleaning scrapers 206 on the cleaning arc plates 203 and the limiting arc plates 205, and are staggered to avoid cleaning blind spots and ensure cleaning effect.

[0051] Based on the above embodiments, it can be concluded that: in use, the cleaning mechanism 2 is installed in the flow-retarding hole 106 of the flow-retarding plate 103. Then, according to the size of the flow-retarding hole 106, by pressing and squeezing the push plate 213, the adjusting arc plate 210 is driven to move inward, so that the limiting block 212 separates from the limiting groove 211. Then, by adjusting the position of the adjusting circular plate 209, under the action of the adjusting push plate 208, the elastic push plate 207 is pushed to deform, which in turn pushes the cleaning arc plate 203 to open outward, so that the cleaning... The arc plate 203 and the cleaning scraper 206 are in contact with the inner wall of the slow flow hole 106. When the wastewater enters the sedimentation tank 102 from the filter box 101, the wastewater flows onto the slow flow plate 103. At the same time, when the wastewater impacts the float plate 215, it drives the arc plate 203 and the cleaning scraper 206 to move up and down in the slow flow hole 106. This can clean the impurities attached to the slow flow hole 106, and prevent the slow flow hole 106 from becoming blocked, which would cause uneven wastewater flow rate distribution and affect the wastewater treatment efficiency.
