Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment sedimentation tank. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, wastewater treatment has become a top priority in environmental protection. In the entire wastewater treatment process, sedimentation tanks, as a core component, play an indispensable role in removing suspended solids and reducing pollutant concentrations. Currently, while existing wastewater treatment sedimentation tanks largely meet daily needs, some shortcomings still urgently require improvement.

[0003] Currently, most wastewater treatment sedimentation tanks on the market are horizontal flow type, which are generally large in size. During long-term operation, large amounts of sludge easily accumulate at the bottom. Existing cleaning methods mainly rely on manual labor, requiring not only emptying the sedimentation tank but also significant investment of manpower and resources, making cleaning quite difficult. Therefore, we propose a new type of wastewater treatment sedimentation tank to effectively solve the above problems and improve wastewater treatment efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment sedimentation tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment sedimentation tank, comprising a sewage sedimentation tank, a sewage discharge pipe installed at the bottom of the sewage sedimentation tank, a truss bridge installed at the top of the sewage discharge pipe, a central operating platform set in the middle of the truss bridge, a high-power asynchronous motor installed at the center of the central operating platform, a rotating column installed at the output end of the lower end of the high-power asynchronous motor, a crossbeam installed on the outside of the bottom end of the rotating column, scrapers installed on both sides of the bottom end of the crossbeam, and a spraying assembly set at the upper end of the rotating column.

[0006] As a further preferred embodiment of this technical solution, the spraying assembly includes a fixed base fixed to the outside of the upper end of the rotating column and spraying platforms installed on the outer walls of both sides of the fixed base. Multiple sets of nozzles are installed at equal intervals at the bottom of both sets of spraying platforms, and a metering pump is installed at the top of both sets of spraying platforms. A storage tank is provided on the side of each metering pump.

[0007] As a further preferred embodiment of this technical solution, the bottom of the inner wall of the sewage sedimentation tank is designed to be inclined, and the bottom ends of the two sets of scrapers are in contact with the bottom of the inner wall of the sewage sedimentation tank.

[0008] As a further preferred embodiment of this technical solution, a sewage outlet is provided at the center of the bottom of the sewage sedimentation tank, and the sewage outlet is connected to a sewage pipe.

[0009] As a further preferred embodiment of this technical solution, both sets of medicine storage tanks are provided with a feeding port at the top.

[0010] As a further preferred embodiment of this technical solution, the input terminals of both the high-power asynchronous motor and the metering pump are electrically connected to an external controller via wires.

[0011] This utility model provides a wastewater treatment sedimentation tank, which has the following beneficial effects:

[0012] 1. This utility model uses a truss bridge installed on a sewage sedimentation tank, with a high-power asynchronous motor installed in the middle of the truss bridge. The high-power asynchronous motor drives a rotating column to rotate, and the crossbeam at the bottom of the rotating column drives two sets of scrapers to rotate along the bottom of the sewage sedimentation tank. During the rotation, the two sets of scrapers scrape the sludge at the bottom of the sewage sedimentation tank, so that the sludge outside the two sets of scrapers gradually moves towards the middle of the bottom of the sewage sedimentation tank and is discharged outward through the sewage pipe. This effectively cleans the sludge at the bottom of the sewage sedimentation tank and reduces the difficulty of sludge cleaning.

[0013] 2. This utility model has two sets of spraying platforms installed on the upper end of the rotating column. By adding the agent into the storage tank and then starting the metering pump, the agent in the storage tank is evenly sprayed downward through multiple sets of nozzles at the bottom of the spraying platform. The two sets of spraying platforms can rotate under the drive of the rotating column, so that the multiple sets of nozzles at the bottom of the two sets of spraying platforms can deliver the agent to the surface of the sewage inside the sewage sedimentation tank without dead angles, ensuring that the agent can be evenly mixed with the sewage in the sewage sedimentation tank.

[0018] 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.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, a sewage treatment sedimentation tank includes a sewage sedimentation tank 1. A sewage discharge pipe 2 is installed at the bottom of the sewage sedimentation tank 1, and a truss bridge 3 is installed at the top of the sewage discharge pipe 2. A central operating platform 4 is provided in the middle of the truss bridge 3. A high-power asynchronous motor 5 is installed at the center of the central operating platform 4. A rotating column 6 is installed at the output end of the lower end of the high-power asynchronous motor 5. A crossbeam 7 is installed on the outside of the bottom end of the rotating column 6. Scrapers 8 are installed on both sides of the bottom end of the crossbeam 7. A spraying assembly is provided at the upper end of the rotating column 6.

[0023] A truss bridge 3 is installed on the sewage sedimentation tank 1, and a high-power asynchronous motor 5 is installed in the middle of the truss bridge 3. The high-power asynchronous motor 5 drives the rotating column 6 to rotate, and the crossbeam 7 at the bottom of the rotating column 6 drives two sets of scrapers 8 to rotate along the bottom of the sewage sedimentation tank 1. During the rotation, the two sets of scrapers 8 scrape the sludge at the bottom of the sewage sedimentation tank 1, so that the sludge moves under the action of the two sets of scrapers 8. With the continuous movement of the scrapers 8, the sludge outside the two sets of scrapers 8 gradually moves closer to the middle of the bottom of the sewage sedimentation tank 1 and is discharged outward along the sewage pipe 2. This effectively cleans the sludge at the bottom of the sewage sedimentation tank 1 and reduces the difficulty of sludge cleaning.

[0024] In other embodiments, the spraying assembly includes a fixed base 9 fixed to the outside of the upper end of the rotating column 6 and spraying platforms 10 installed on the outer walls of both sides of the fixed base 9. Multiple sets of nozzles 11 are installed at equal intervals at the bottom of both spraying platforms 10. A metering pump 12 is installed at the top of both spraying platforms 10. A storage tank 13 is provided on the side of each metering pump 12.

[0025] By installing two sets of spraying platforms 10 on the upper end of the rotating column 6, the agent can be added into the storage tank 13. Then, by starting the metering pump 12, the agent in the storage tank 13 can be evenly sprayed downward through multiple sets of nozzles 11 at the bottom of the spraying platform 10. The two sets of spraying platforms 10 can rotate under the drive of the rotating column 6, so that the multiple sets of nozzles 11 at the bottom of the two sets of spraying platforms 10 can deliver the agent to the surface of the sewage inside the sewage sedimentation tank 1 without dead angles, ensuring that the agent can be evenly mixed with the sewage in the sewage sedimentation tank 1.

[0026] In other embodiments, the bottom of the inner wall of the sewage sedimentation tank 1 is designed to be inclined, and the bottom ends of the two sets of scrapers 8 are attached to the bottom of the inner wall of the sewage sedimentation tank 1.

[0027] The inclined design of the bottom of the sewage sedimentation tank 1 causes the sludge at the bottom of the sewage sedimentation tank 1 to gather towards the middle, and the two sets of scrapers 8 can also further gather the sludge towards the middle when pushing the sludge at the bottom of the sewage sedimentation tank 1.

[0028] In other embodiments, a sewage outlet is provided at the center of the bottom end of the sewage sedimentation tank 1, and the sewage outlet is connected to the sewage pipe 2;

[0029] With this design, as the scraper 8 scrapes the sludge at the bottom of the sewage sedimentation tank 1, the sludge can be allowed to enter the sewage pipe 2 through the sewage outlet.

[0030] In other embodiments, both sets of medicine storage tanks 13 are provided with feeding ports at their top;

[0031] With this design, when it is necessary to add medicine to the medicine storage tank 13, the rotating column 6 can be used to remove the spraying platform 10 and move it to the vicinity of the truss bridge 3, so that the medicine can be added to the inside of the feeding port on the medicine storage tank 13 on the truss bridge 3.

[0032] In other embodiments, the input terminals of both the high-power asynchronous motor 5 and the metering pump 12 are electrically connected to an external controller via wires.

[0033] This design allows an external controller to control the start and stop of the high-power asynchronous motor 5 and the metering pump 12 in real time, thereby ensuring that the high-power asynchronous motor 5 and the metering pump 12 can operate normally for a long time.

[0034] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
