Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and more specifically to a filtration device for industrial wastewater treatment. Background Technology

[0002] With the rapid development of industry, the amount of wastewater discharged during industrial production is increasing year by year. If discharged directly without effective treatment, it will pollute water resources and threaten ecological balance and human health. Therefore, industrial wastewater treatment has become an indispensable and crucial link in industrial production. In the industrial wastewater treatment process, the filtration device, as one of the core equipment, plays a key role in removing solid impurities from the wastewater, providing clean wastewater that meets standards for subsequent chemical reaction treatment, and directly affecting the overall wastewater treatment efficiency and final treatment effect.

[0003] Research revealed that many traditional filtration devices employ single-stage or multi-stage fixed filter plate structures. For example, some devices use multiple layers of filter plates with decreasing pore sizes, allowing wastewater to flow through each layer sequentially for filtration. Large particles are first intercepted by the upper, larger-pore filter plates, while smaller particles are retained at the lower, smaller-pore filter plates. While this structure can purify wastewater to some extent, during long-term operation, solid impurities in the wastewater easily accumulate on the filter plate surface, gradually clogging the filter pores and causing a continuous decrease in filtration flow rate.

[0004] Shortcomings of existing technologies: In practical applications, existing industrial wastewater treatment filtration devices still have many problems that need to be solved. Most filtration devices adopt a single-stage or multi-stage fixed filter plate structure. During long-term filtration operations, solid impurities in the wastewater tend to accumulate on the surface of the filter plates and clog the filter holes, resulting in a gradual decrease in filtration flow rate. This not only reduces wastewater treatment efficiency but also requires frequent shutdowns to disassemble and clean the filter plates, increasing labor maintenance costs and equipment downtime. Some filtration devices with anti-clogging functions are mostly designed for cleaning only a single filter plate and cannot achieve simultaneous cleaning of multiple filter plates, resulting in low cleaning efficiency and the possibility of incomplete cleaning during the cleaning process.

[0005] Therefore, there is a need to provide a filtration device for industrial wastewater treatment to solve the problems mentioned above. Utility Model Content

This ensures that harmful substances in the wastewater can fully react with the chemicals, improving the thoroughness of wastewater treatment and providing a strong guarantee for subsequent wastewater discharge or reuse that meets standards. This further enhances the wastewater treatment efficiency and quality of the entire device. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0023] Example 1 This utility model is a filtration device for industrial wastewater treatment, including a workbench 1, with support legs 2 fixedly connected to the four corners of the bottom of the workbench 1, a wastewater treatment tank 5 fixedly connected to the top of the workbench 1 near the left side, an inlet pipe 6 fixedly connected to the top of the wastewater treatment tank 5, a water tank 8 fixedly connected to the top of the workbench 1 near the right side, a first filter plate 9 fixedly connected to the inside of the wastewater treatment tank 5 near the top, a second filter plate 11 fixedly connected to the inside of the wastewater treatment tank 5 near the middle, and an outlet pipe 10 fixedly sleeved between the bottom middle of the wastewater treatment tank 5 and the middle of the workbench 1. The filtration devices for industrial wastewater treatment also include: Anti-clogging component 4 is installed inside the sewage treatment tank 5 between the first filter plate 9 and the second filter plate 11, and is used to simultaneously clean the impurities accumulated on the first filter plate 9 and the second filter plate 11. The stirring component 3 is located inside the wastewater treatment tank 5 near the bottom and is used to mix and stir the filtered industrial wastewater with the treatment chemicals. Pipeline assembly 7 is located between anti-clogging assembly 4 and water tank 8, and is used to assist in the movement of anti-clogging assembly 4.

[0024] Anti-clogging component 4 includes: A guide rod 410 is slidably sleeved on the outer wall of the guide rod 410. A high-pressure tube plate 405 is fixedly connected to the top of the outer wall of the movable tube plate 406 via a connecting rod. A cleaning brush rod 409 is fixedly connected to the bottom of the outer wall of the movable tube plate 406 via a connecting rod. A connecting plate 407 is fixedly connected to the middle of the opposite side of the cleaning brush rod 409 and the high-pressure tube plate 405. The cleaning brush rod 409 is movably set on the top of the second filter plate 11. The drive mechanism is located on the left side of the movable collar 406 and is used to drive the movable collar 406 to move the high-pressure tube sheet 405 and the cleaning brush rod 409.

[0025] The drive mechanism includes a drive motor 401. The bottom end of the drive motor 401 is fixedly connected to the front side of the sewage treatment tank 5 via a fixing plate. The transmission end of the drive motor 401 passes through the sewage treatment tank 5 and is fixedly connected to a lead screw 403. A threaded sleeve block 404 is threadedly sleeved on the outer wall of the lead screw 403. The outer wall of the threaded sleeve block 404 is fixedly connected to the outer wall of the movable collar 406 via a connecting rod. Limiting blocks 402 are movably sleeved on the outer walls of both ends of the lead screw 403 and the guide rod 410. The outer walls of the four limiting blocks 402 are fixedly connected to the inner wall of the sewage treatment tank 5.

[0026] The pipeline assembly 7 includes a limiting post 702. A water pump 12 is fixedly connected to the right end of the limiting post 702. A spring tube 703 is fixedly connected to the outlet of the water pump 12. A hose 701 is fixedly connected to the left end of the spring tube 703. The left end of the hose 701 passes through the sewage treatment tank 5 and is fixedly connected to the right end of the high-pressure tube plate 405.

[0027] The inner wall of the spring tube 703 is movably connected to the outer wall of the limiting post 702, and the bottom end of the water pump 12 is fixedly connected to the top left side of the water tank 8.

[0028] Both sides of the cleaning brush rod 409 are fixedly connected with convex sliders 408. Both sides of the inner wall of the sewage treatment tank 5 are provided with convex grooves. The outer walls of the two convex sliders 408 are slidably connected in the two convex grooves.

[0029] In this embodiment, as Figure 1-4As shown, the drive motor 401 drives the lead screw 403 to rotate, causing the threaded sleeve block 404 to drive the movable collar 406 to move along the guide rod 410, thereby allowing the high-pressure tube plate 405 and the cleaning brush rod 409 to move synchronously. The cleaning brush rod 409 can physically clean the impurities accumulated on the surface of the second filter plate 11. At the same time, the water pump 12 in the pipeline assembly 7 draws water from the water tank 8 and delivers it to the high-pressure tube plate 405 through the spring tube 703 and the hose 701. The high-pressure tube plate 405 can spray high-pressure water jets onto the bottom of the first filter plate 9 to achieve backwash cleaning of the first filter plate 9.

[0030] Example 2 The difference from Embodiment 1 is that this embodiment discloses that the stirring assembly 3 includes a stirring motor 301. The bottom end of the stirring motor 301 is fixedly connected to the front side of the sewage treatment tank 5 near the bottom end through a fixing plate. The transmission end of the stirring motor 301 passes through the sewage treatment tank 5 and is fixedly connected to a stirring rod 302. The two ends of the stirring rod 302 are rotatably sleeved with the inner wall of the sewage treatment tank 5.

[0031] In this embodiment, as Figure 1-2 and Figure 5 As shown, the stirring motor 301 drives the stirring rod 302 to rotate at the bottom of the sewage treatment tank 5, which can quickly and thoroughly mix the filtered sewage with the added treatment solution, avoiding the problem of insufficient reaction caused by local accumulation of the solution.

[0032] The working principle of this utility model is as follows: Industrial wastewater first enters the device through the inlet pipe 6 at the top of the wastewater treatment tank 5. The wastewater first flows through the first filter plate 9 near the top of the wastewater treatment tank 5, where the first filter plate 9 performs preliminary interception and filtration of large particulate impurities in the wastewater. After preliminary filtration, the wastewater continues to flow downwards and enters the second filter plate 11 near the middle of the wastewater treatment tank 5. The second filter plate 11 performs secondary filtration of medium and fine particulate impurities in the wastewater. Through two-stage filtration, the content of solid impurities in the wastewater can be significantly reduced, laying the foundation for subsequent chemical treatment. The drive motor 401 in the anti-clogging component 4 is activated. The transmission end of the drive motor 401 drives the lead screw 403 to rotate stably under the constraint of the limit block 402. The threaded sleeve 404 on the outer wall of the lead screw 403 moves along the axial direction of the lead screw 403 due to the threaded engagement. At the same time, the threaded sleeve 404 drives the movable collar 406 along the guide rod through the connecting rod. The rod 410 slides synchronously; the high-pressure pipe plate 405 connected to the top of the movable collar 406 by a connecting rod moves with it, and the cleaning brush rod 409 connected to the bottom by a connecting rod also moves synchronously. The convex sliders 408 on both sides of the cleaning brush rod 409 slide along the convex grooves on the inner wall of the sewage treatment tank 5 to ensure the stability of movement. The cleaning brush rod 409 physically cleans the impurities accumulated on the surface of the second filter plate 11 to prevent impurities from clogging the filter holes of the second filter plate 11. After the sewage has been filtered in two stages and the anti-clogging cleaning has been completed, the sewage continues to flow downward to the area near the bottom of the sewage treatment tank 5. At this time, the stirring assembly 3 is started. The transmission end of the stirring motor 301 drives the stirring rod 302 to rotate in the sewage treatment tank 5. After adding sewage treatment chemicals to the bottom area of ​​the sewage treatment tank 5, the rotation of the stirring rod 302 can fully stir and mix the sewage and chemicals to ensure that the harmful substances in the sewage can fully react with the chemicals.

[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
