Description

Technical Field

[0001] This application relates to the field of wastewater treatment, specifically to a flocculation auxiliary device for wastewater treatment. Background Art

[0002] In modern production and daily life, wastewater treatment, transforming it into industrial or domestic water that meets standards, is an important means of water resource reuse and reducing waste. Therefore, numerous wastewater treatment plants have been built in cities to purify daily wastewater. This process involves the targeted addition of different types and proportions of flocculants to different types and conditions of wastewater, causing suspended solids in the water to coagulate and form larger flocs, facilitating subsequent sedimentation or filtration. However, due to the different components of wastewater, the type and concentration of flocculants required vary, affecting the actual impact on the water body. Since flocculation may involve errors, it is necessary to sample and analyze different water layers at different time points after the flocculant is added. The sampling data is used to determine the flocculation state of different water layers, so as to adjust the flocculant composition and concentration, provide data support for subsequent additions, ensure the effectiveness of wastewater treatment, and reduce flocculant waste. However, since sampling of flocculation requires simultaneous collection of flocs to obtain accurate water data, large flocs can easily clog the sampler, resulting in poor collection efficiency. Furthermore, flocs clogging the pipes may enter samples from different water layers during collection, leading to inaccurate water data.

[0003] Therefore, this application designs a flocculation auxiliary device for wastewater treatment that can prevent flocculation and facilitate water exchange when sampling at different water layers. Utility Model Content

[0004] The purpose of this invention is to provide a flocculation auxiliary device for wastewater treatment, which aims to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flocculation auxiliary device for sewage treatment, comprising a sewage tank, an electric displacement mechanism, an electric multi-stage telescopic rod, a collection mechanism, and an anti-clogging mechanism to prevent clogging during the collection of flocculated water; the electric displacement mechanism is slidably connected to the side wall of the sewage tank, the electric multi-stage telescopic rod is slidably connected to the electric displacement mechanism, the upper end of the collection mechanism is inserted into the electric multi-stage telescopic rod, and the anti-clogging mechanism is inserted into the collection mechanism; the collection mechanism is provided with a transfer chamber, and the anti-clogging mechanism is provided with a water flow drive wheel; the extension and retraction of the electric multi-stage telescopic rod drives the collection mechanism to move up and down within the sewage tank, and the water flow drive wheel is driven by the water transfer chamber when the collection mechanism moves upward, thereby driving the anti-clogging mechanism to scrape off and break up the flocs about to enter the transfer chamber to a certain extent.

[0006] The electric multi-stage telescopic rod propels the collection mechanism vertically within the water body to reach different water layers for flocculation sampling. The mechanism stores energy during descent and releases it during ascent, allowing it to agitate and divert water within the transfer chamber, facilitating water exchange. The resulting water flow drives a water-driven wheel, which in turn rotates an anti-clogging mechanism to scrape away and break up large flocs to some extent, preventing blockage in the transfer chamber and ensuring smooth water exchange. This effectively improves the accuracy of collected data, enhances wastewater treatment, and reduces subsequent flocculant waste.

[0007] Furthermore, the sliding connection between the electric multi-stage telescopic rod and the electric displacement mechanism is an electric sliding connection, so that the electric multi-stage telescopic rod can slide to any position along the electric displacement mechanism, and the electric displacement mechanism can move horizontally along the side wall of the sewage tank.

[0008] The electric displacement mechanism and electric multi-stage telescopic rod allow the collection mechanism to be moved to any position within the sewage tank, enabling the collection of flocculated water from any location within the sewage tank. This effectively improves the applicability of the device and enhances the breadth and accuracy of the sampling data.

[0009] Furthermore, the collection mechanism includes a protective shell, an openable rear cover, a sampling chamber, a solenoid valve, and a drainage assembly; the transfer chamber is located inside the protective shell, the openable rear cover is hinged to the rear of the protective shell, the sampling chamber is provided with an array of sampling chambers, the array of sampling chambers are interconnected and fixedly connected to the inner wall of the protective shell, the sampling chamber is connected to the transfer chamber, a solenoid valve is provided at the connection between the sampling chamber and the transfer chamber, the drainage assembly is inserted into the protective shell, and openings are provided at the upper and lower ends of the protective shell to allow the transfer chamber to communicate with the outside.

[0010] Furthermore, the drainage assembly includes a turbine, a first gear, a second gear, a connecting rod, a winding reel, a cable assembly, and a torsion spring; the upper end of the turbine is rotatably connected to the anti-clogging mechanism, the lower end of the turbine is fixedly connected to the first gear, one end of the connecting rod is inserted into the second gear, the other end of the connecting rod passes through the protective shell and is inserted into the winding reel, the middle part of the connecting rod is rotatably connected to the protective shell, and the first gear and the second gear mesh; the cable assembly is wound on the winding reel, one end of the cable assembly is fixedly connected to the winding reel, and the other end of the cable assembly is tied to the middle of the electric multi-stage telescopic rod; the end of the winding reel away from the connecting rod is inserted into the torsion spring, and the lower end of the torsion spring housing is welded to the protective shell.

[0011] By using a winding reel and a torsion spring, the torsion spring rotates and stores energy when the protective shell is driven to descend, and releases energy when the protective shell rises. This energy is then transmitted to drive a turbine to rotate and divert water, thereby exchanging the water in the transfer chamber. The water exchange can be completed automatically when the collection mechanism changes its collection position, preventing the mixing and contamination of samples from different water layers and further improving the accuracy of the collected data.

[0012] Furthermore, the anti-clogging mechanism includes a first filter plate, a second filter plate, a scraper, and a rotating rod. The first filter plate is inserted into the upper opening of the protective shell, and the second filter plate is hinged to the lower opening of the protective shell. One end of the rotating rod is rotatably connected to the middle of the upper part of the first filter plate, and the other end of the rotating rod is inserted into the water flow drive wheel. The two sides of the middle part of the rotating rod are inserted into the scraper. The hinge at the lower opening of the protective shell has a limit, so that the second filter plate can only open and close to the end away from the protective shell.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This invention provides a flocculation auxiliary device for wastewater treatment. An electrically operated multi-stage telescopic rod propels a collection mechanism vertically within the water body to reach different water layers for flocculation sampling. The device stores energy during descent and releases it during ascent, allowing the collection mechanism to agitate and divert water within the transfer chamber, exchanging water inside and outside the chamber. The resulting water flow drives a water-driven wheel, which in turn rotates an anti-clogging mechanism to scrape away and break up large flocs to some extent, preventing blockage of the transfer chamber and ensuring smooth water exchange. This effectively improves the accuracy of collected data, enhances wastewater treatment efficiency, and reduces subsequent flocculant waste.

[0015] The electric displacement mechanism and electric multi-stage telescopic rod allow the collection mechanism to be moved to any position within the sewage tank, enabling the collection of flocculated water from any location within the sewage tank. This effectively improves the applicability of the device and enhances the breadth and accuracy of the sampling data.

[0016] By using a winding reel and a torsion spring, the torsion spring rotates and stores energy when the protective shell is driven to descend, and releases energy when the protective shell rises. This energy is then transmitted to drive a turbine to rotate and divert water, thereby exchanging the water in the transfer chamber. The water exchange can be completed automatically when the collection mechanism changes its collection position, preventing the mixing and contamination of samples from different water layers and further improving the accuracy of the collected data.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1 to 7 As shown, this utility model provides the following technical solution: a flocculation auxiliary device for sewage treatment, including a sewage tank 1, an electric displacement mechanism 2, an electric multi-stage telescopic rod 3, a collection mechanism 4, and an anti-clogging mechanism 5 to prevent clogging during the collection of flocculated water; the electric displacement mechanism 2 is slidably connected to the side wall of the sewage tank 1, the electric multi-stage telescopic rod 3 is slidably connected to the electric displacement mechanism 2, the upper end of the collection mechanism 4 is inserted into the electric multi-stage telescopic rod 3, and the anti-clogging mechanism 5 is inserted into the collection mechanism 4; the collection mechanism 4 is provided with a transfer chamber 6, and the anti-clogging mechanism 5 is provided with a water flow drive wheel 7. The extension and retraction of the electric multi-stage telescopic rod 3 drives the collection mechanism 4 to move up and down in the sewage tank 1. The water flow drive wheel 7 is driven by the water transfer chamber 6 when the collection mechanism 4 moves upward, which drives the anti-clogging mechanism 5 to scrape off and break up the flocs that are about to enter the transfer chamber 6.

[0027] As another embodiment, such as Figure 2As shown, the sliding connection between the electric multi-stage telescopic rod 3 and the electric displacement mechanism 2 is an electric sliding connection, allowing the electric multi-stage telescopic rod 3 to slide to any position along the electric displacement mechanism 2, and the electric displacement mechanism 2 to move horizontally along the side wall of the sewage tank 1. The sliding connection is electric, and can utilize existing technologies such as electric push rods or threaded rods with threaded sleeves, driven by a motor. This allows the electric displacement mechanism 2 to move horizontally along the horizontal groove on the inner wall of the sewage tank 1, while the electric multi-stage telescopic rod 3 can move horizontally on the surface of the electric displacement mechanism 2, enabling it to move the collection mechanism 4 to any position on the water surface.

[0028] The electric multi-stage telescopic rod 3 can be detached from the electric displacement mechanism 2, thereby simultaneously bringing out the collection mechanism 4 and the anti-blocking mechanism 5, which facilitates the handling of sample tubes and the maintenance of the device.

[0029] As another embodiment, such as Figures 3 to 6 As shown, the collection mechanism 4 includes a protective shell 41, an openable rear cover 42, a sampling chamber 43, a solenoid valve 44, and a drainage assembly 45. The transfer chamber 6 is located inside the protective shell 41. The openable rear cover 42 is hinged to the rear of the protective shell 41. The sampling chamber 43 has an array of sampling chambers connected to each other and fixedly connected to the inner wall of the protective shell 41. The sampling chamber 43 communicates with the transfer chamber 6. A solenoid valve 44 is installed at the connection between the sampling chamber 43 and the transfer chamber 6. The drainage assembly 45 is inserted into the protective shell 41. The openable rear cover 42 has a waterproof seal, preventing water ingress when closed. Opening the openable rear cover 42 allows the sample tube to be inserted into the sampling chamber 43, or the sample tube can be removed after sampling.

[0030] When it is necessary to collect flocculated water, the electric displacement mechanism 2 and the electric multi-stage telescopic rod 3 drive the collection mechanism 4 to the water surface at the collection point. Then, the electric multi-stage telescopic rod 3 is activated, pushing the protective shell 41 to sink to the deepest water layer for collection, thus preparing to start collecting flocculated water.

[0031] See Figure 3 The protective shell 41 has openings at both the upper and lower ends to allow the transfer cavity 6 to communicate with the outside.

[0032] See Figures 3 to 6The drainage assembly 45 includes a turbine 451, a first gear 452, a second gear 453, a connecting rod 454, a winding reel 455, a wire assembly 456, and a torsion spring 457. The upper end of the turbine 451 is rotatably connected to the anti-clogging mechanism 5, and the lower end of the turbine 451 is fixedly connected to the first gear 452. One end of the connecting rod 454 is inserted into the second gear 453, and the other end of the connecting rod 454 passes through the protective shell 41 and is inserted into the winding reel 455. The middle part of the connecting rod 454 is rotatably connected to the protective shell 41. The first gear 452 and the second gear 453 mesh. The wire assembly 456 is wound on the winding reel 455. One end of the wire assembly 456 is fixedly connected to the winding reel 455, and the other end of the wire assembly 456 is tied to the middle part of the electric multi-stage telescopic rod 3. The end of the winding reel 455 away from the connecting rod 454 is inserted into the torsion spring 457, and the lower end of the outer shell of the torsion spring 457 is welded to the protective shell 41. Both the first gear 452 and the second gear 453 can use a combination of bevel gears and bevel gears to reduce friction and thus reduce transmission loss. Furthermore, a waterproof cover can be installed on their exterior, and a rotating seal can be used for protection to prevent transmission loss caused by the rotation of the first gear 452 and the second gear 453 in water, and to extend their service life.

[0033] When the electric multi-stage telescopic rod 3 pushes the protective shell 41 downward, the wire assembly 456 is driven by friction to rotate the winding wheel 455, which in turn drives the torsion spring 457 to rotate and store power. After reaching the deepest sampling point, the corresponding solenoid valve 44 opens, and the flocculated water filtered by the anti-clogging mechanism 5 is immersed into the sample tube of the sampling chamber 43 through the transfer chamber 6 and the solenoid valve 44. After completion, the solenoid valve 44 closes, the electric multi-stage telescopic rod 3 retracts, and the sampling mechanism 4 moves upward to the next sampling point.

[0034] During the ascent, the torsion spring is released, causing the winding reel 455 to rotate and retract the wire assembly 456. At the same time, it drives the connecting rod 454 to rotate, which in turn drives the second gear 453 to rotate. The rotation of the second gear 453 drives the first gear 452, which meshes with it, to rotate. The first gear 452 then drives the turbine 451 to rotate rapidly, disturbing and guiding the water body. The water body above the protective shell 41 is guided into the transfer chamber 6 and discharged from the lower part of the protective shell 41. In this process, the water body exchange is completed quickly, avoiding the carry of the lower layer of flocculated water body to the next collection point. In this way, the collection can be carried upwards.

[0035] As another embodiment, such as Figure 3 , Figure 4 as well as Figure 7As shown, the anti-clogging mechanism 5 includes a first filter plate 51, a second filter plate 52, a scraper 53, and a rotating rod 54; the first filter plate 51 is inserted into the upper opening of the protective shell 41, the second filter plate 52 is hinged to the lower opening of the protective shell 41, one end of the rotating rod 54 is rotatably connected to the middle of the upper end of the first filter plate 51, the other end of the rotating rod 54 is inserted into the water flow drive wheel 7, and the two sides of the middle part of the rotating rod 54 are inserted into the scraper 53. When the collection mechanism 4 completes a collection and rises, the turbine 451 rotates, causing disturbance and diversion of the water. This allows the water to enter the transfer chamber 6 through the water flow drive wheel 7 and the first filter plate 51. Large flocs are blocked by the first filter plate 51, while the water flow drive wheel 7 rotates during the ascent, which in turn drives the rotating rod 54 to rotate. The rotating rod 54 then drives the scraper 53 to scrape off and break up the large flocs on the first filter plate 51 to a certain extent, allowing small flocs to pass through the first filter plate 51 and enter the transfer chamber 6, where they are discharged together with the water through the second filter plate 52.

[0036] It should be noted that the hinge at the lower opening of the protective shell 41, where the second filter plate 52 is connected, has a limit switch, allowing the second filter plate 52 to open and close towards the end away from the protective shell 41. This ensures that the second filter plate 52 is closed when the protective shell 41 descends, preventing impurities in the water from entering the transfer chamber 6, and opens due to water flow when the protective shell 41 rises, preventing flocculent material from being trapped inside the transfer chamber 6 and affecting sampling accuracy.

[0037] Working principle: Before use, first open the closable rear cover 42, insert the sample tube into the sampling chamber 43, and then connect the electric multi-stage telescopic rod 3 to the electric displacement mechanism 2. When it is necessary to collect data, the electric displacement mechanism 2 and the electric multi-stage telescopic rod 3 can drive the collection mechanism 4 to move to any position on the water surface. Then the electric multi-stage telescopic rod 3 starts to push the collection mechanism 4 to the deepest collection point. During this process, the line group 456 extends and drives the winding wheel 455 to rotate, which in turn drives the torsion spring 457 to rotate and store energy.

[0038] Upon reaching the deepest sampling point, the corresponding solenoid valve 44 opens. The flocculated water, filtered by the anti-clogging mechanism 5, is then immersed in the sample tube of the sampling chamber 43 through the solenoid valve 44 from the transfer chamber 6. After completion, the solenoid valve 44 closes, and the electric multi-stage telescopic rod 3 retracts, moving the sampling mechanism 4 upwards to the next sampling point. During the ascent, the torsion spring releases, causing the winding reel 455 to rotate and retract the wire assembly 456. This, in turn, drives the turbine 451 to rotate rapidly, disturbing and diverting the water, guiding the water above the protective shell 41 into the transfer chamber 6 and discharging it from the bottom of the protective shell 41. As the sampling mechanism 4 rises, the turbine 45... The rotation disturbs and diverts the water, allowing it to enter the transfer chamber 6 through the first filter plate 51. Large flocs are blocked by the first filter plate 51. The water flow drive wheel 7 rotates during its ascent, which in turn drives the scraper 53 to scrape off and break up the large flocs on the first filter plate 51 to a certain extent, allowing smaller flocs to pass through the first filter plate 51 into the transfer chamber 6. They are then discharged from the second filter plate 52 along with the water. Subsequently, samples are collected at the corresponding collection points. After all collection points are completed, the device is removed, the openable rear cover 42 is opened, and the sample tube filled with flocculent water is taken out.

[0039] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
