Abstract

This invention provides a water treatment device for groundwater pollution prevention and control, relating to the field of water treatment technology. It includes a groundwater treatment tank with an anti-clogging mechanism fixedly installed at its lower end. The anti-clogging mechanism includes a motor. A mixing main shaft is fixedly installed inside the groundwater treatment tank, located at its center. By activating the motor, not only can the groundwater inside the tank be thoroughly flocculated and mixed, but the rotating shaft also drives a scraper plate to rotate inside the pipe. When the groundwater is subsequently discharged, the groundwater will carry some floating flocculent material that will clog the guide plates on the filter screen.

Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, and more specifically, relates to a water treatment device for the prevention and control of groundwater pollution. Background Technology

[0002] Groundwater refers to water that exists in underground rock layers or soil pores in nature. These water sources usually come from rainwater seeping into the ground or surface water seeping into the underground layers. Groundwater plays an important role in the Earth's water cycle. Groundwater is usually used for drinking water supply, agricultural irrigation, industrial production, and other purposes. However, when groundwater is polluted, the quality of urban water supply drops significantly. At this time, water treatment equipment is needed to treat the polluted groundwater by flocculation, filtration, disinfection, etc., to ensure that the water quality meets health standards, thereby protecting people's health and quality of life.

[0003] When existing water treatment devices treat groundwater, the groundwater carries some impurities such as mud and sand during its flow, so flocculation is required. In order to improve flocculation efficiency, existing water treatment devices usually add a mixing shaft in the center of the water treatment tank to improve the reaction efficiency between flocculant and groundwater. However, the rotation of the mixing shaft will break up some of the flocculated clusters, making it easy for the water flow to carry the clusters and get stuck at the filter screen during subsequent groundwater transportation, thus affecting the groundwater transportation efficiency. Its practicality needs to be improved.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a water treatment device for the prevention and control of groundwater pollution, in order to achieve a more practical value. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a water treatment device for groundwater pollution prevention and control, thereby resolving the problems described above.

[0006] A water treatment device for groundwater pollution prevention and control includes a groundwater treatment tank, a controller is fixedly installed on the side wall of the groundwater treatment tank, and a water inlet is provided on the side wall of the groundwater treatment tank away from the controller.

[0007] An anti-blocking mechanism is fixedly installed at the lower end of the underground water treatment tank;

[0008] The anti-clogging mechanism includes a motor, and a mixing spindle is fixedly installed inside the underground water treatment tank. The mixing spindle is located at the center inside the underground water treatment tank. The output shaft of the motor is fixedly installed with the mixing spindle. The anti-clogging mechanism also includes pipes, circular grooves, annular grooves, rotating rings, rotating shafts, synchronous belts, first storage grooves, acrylic observation windows, second storage grooves, guide grooves, concave limiting grooves, guide blocks, U-shaped blocks, limiting base plates, filters, guide plates, and scraping plates.

[0009] Preferably, the underground water treatment tank has a through-hole outlet channel, and an electrically controlled valve is installed inside the outlet channel. The pipe is located on the surface of the outlet channel and is fixedly installed with the outlet channel. Two circular grooves are opened inside the pipe and are parallel to each other. Two annular grooves are opened on the inner wall of the circular grooves. Two rotating rings are located inside the annular grooves and are rotatably installed with the annular grooves. The rotating shaft is located between the rotating rings and is fixedly installed with the rotating rings and rotatably installed with the circular grooves.

[0010] Preferably, the rotating shaft is exposed below the pipe, the synchronous belt is located between the output shaft of the motor and the rotating shaft, the output shaft of the motor is rotatably mounted to the rotating shaft and the synchronous belt, the first storage slot is opened through the inside of the pipe, the acrylic observation window is located inside the first storage slot and is fixedly installed with the first storage slot, the second storage slot is opened through the side wall of the first storage slot, and both guide slots are opened on the inner wall of the second storage slot.

[0011] Preferably, the concave limiting groove is formed between the guide grooves, the concave limiting groove is located below the first placement groove, the two guide blocks are both located between the guide grooves, the two guide blocks are slidably installed with the guide grooves, the U-shaped block is located between the guide blocks, the U-shaped block is fixedly installed with the guide blocks, the U-shaped block is slidably installed with the second placement groove, the limiting base plate is located inside the concave limiting groove, and the limiting base plate is slidably installed with the concave limiting groove.

[0012] Preferably, the filter screen is located at the upper end of the limiting base plate, the filter screen is fixedly installed with the limiting base plate, one end of the filter screen is arc-shaped, each guide plate is located on the side frame of the filter screen, each guide plate is fixedly installed with the filter screen, each scraper is located on the circumferential surface of the rotating shaft, each scraper is fixedly installed with the rotating shaft, the end portion of each scraper is located between the guide plates, and each scraper is adapted to the guide plate and the filter screen.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, turning on the motor not only allows for thorough flocculation of the groundwater inside the groundwater treatment tank and ensures complete mixing with the groundwater, but also drives the rotating shaft to rotate in the circular groove via a synchronous belt. This rotating shaft then drives the scraper plate to rotate inside the pipe. Since the water flows out through the holes of the filter screen, when the groundwater is discharged later, some of the floating flocs can easily clog the holes of the filter screen, i.e., between the guide plates. At this time, because the end of the scraper plate is located inside the guide plate, the rotating shaft can drive the scraper plate to scrape away the clusters that are clogged between the guide plates, preventing the clusters of flocs from blocking the holes of the filter screen and affecting the transport of groundwater, thus improving the treatment efficiency.

[0015] In this invention, by using a motor to drive the mixing spindle and the scraper of the rotating shaft to rotate, not only can the groundwater be initially flocculated and the filter screen be prevented from clogging, but also when the electrically controlled valve is raised, the rotation of the mixing spindle and the scraper of the rotating shaft will generate a centrifugal force, which can provide a dual guiding effect on the water flow when the groundwater is transported to the pipeline and the filter screen, making the water flow more uniform and increasing the stability of groundwater treatment.

[0016] In this invention, by using a motor to drive the mixing spindle and the scraper of the rotating shaft to rotate via a synchronous belt, it can not only provide guidance during groundwater treatment, but also prevent the filter screen from clogging. In addition, since the same motor is used for the mixing spindle, it can also achieve a certain energy-saving effect, making it quite practical.

[0017] In this invention, by setting a rotating ring and annular groove, the rotating ring on the rotating shaft can slide in the circular groove and annular groove when the synchronous belt drives the rotating shaft to rotate, thereby providing multiple limiting measures and preventing the rotating shaft from shaking when rotating because the rotating shaft is only subjected to the force of the synchronous belt rotation from below, thus increasing stability.

[0018] In this invention, by pulling the U-shaped block upwards, the U-shaped block can move the guide block, the limiting base plate, and the filter screen within the guide groove and the second placement groove, thereby allowing the filter screen to be removed as a whole. This facilitates the use of a high-pressure water gun to rinse the filter screen, the underground water treatment tank, and the inside of the pipes. At the same time, by setting the limiting base plate and the guide block, the filter screen is kept in a parallel state when placed, preventing it from being tilted and causing some flocculent material to flow out from the holes at the tilted part of the filter screen during subsequent flocculent material interception, thus improving portability.

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] Please see Figures 1-9 The present invention provides a water treatment device for groundwater pollution prevention and control, including a groundwater treatment tank 11, a controller 12 fixedly installed on the side wall of the groundwater treatment tank 11, and a water inlet 13 provided on the side wall of the groundwater treatment tank 11 away from the controller 12.

[0031] An anti-clogging mechanism is fixedly installed at the lower end of the underground water treatment tank 11;

[0032] The anti-clogging mechanism includes a motor 14. A mixing spindle 15 is fixedly installed inside the groundwater treatment tank 11, located at the center of the tank. The output shaft of the motor 14 is fixedly installed with the mixing spindle 15. The anti-clogging mechanism also includes a pipe 18, a circular groove 19, an annular groove 21, a rotating ring 22, a rotating shaft 23, a synchronous belt 24, a first storage trough 25, an acrylic observation window 26, a second storage trough 27, a guide groove 28, a concave limiting groove 29, a guide block 31, a U-shaped block 32, a limiting base plate 33, a filter screen 34, a guide plate 35, and a scraper plate 36. By turning on the motor 14, the groundwater inside the groundwater treatment tank 11 can be fully flocculated and mixed with the groundwater. The water is thoroughly mixed to achieve flocculation. At the same time, the rotation of the motor 14 will drive the rotating shaft 23 to rotate in the circular groove 19 via the synchronous belt 24. This causes the rotating shaft 23 to drive the scraper plate 36 to rotate inside the pipe 18. Since the water flows out through the holes of the filter screen 34, when the groundwater is discharged later, the groundwater may carry some floating flocculent material and block it in the various holes of the filter screen 34, that is, between the guide plates 35. At this time, since the end of the scraper plate 36 is located inside the guide plate 35, the rotating shaft 23 can drive the scraper plate 36 to scrape the clusters blocked between the guide plates 35, so as to prevent the clusters of flocculent material from blocking the holes of the filter screen 34 and affecting the transport of groundwater, thereby improving the treatment efficiency.

[0033] An outlet channel 16 is formed through the interior of the underground water treatment tank 11. An electrically controlled valve 17 is installed inside the outlet channel 16. A pipe 18 is located on the surface of the outlet channel 16 and is fixedly installed thereto. Two circular grooves 19 are formed inside the pipe 18 and are parallel to each other. Two annular grooves 21 are formed on the inner wall of the circular grooves 19. Two rotating rings 22 are located inside the annular grooves 21 and are rotatably mounted to them. A rotating shaft 23 is located between the rotating rings 22 and is fixedly mounted to them. The rotating shaft 23 is rotatably mounted to the circular grooves 19, with a portion of the rotating shaft 23 exposed below the pipe 18. A synchronous belt 24 is located between the output shaft of the motor 14 and the rotating shaft 23, and the output shaft of the motor 14 rotates with the rotating shaft 23 and the synchronous belt 24. The installation, by setting the rotating ring 22 and the ring groove 21, allows the rotating ring 22 on the rotating shaft 23 to slide within the circular groove 19 and the ring groove 21 when the synchronous belt 24 drives the rotating shaft 23 to rotate. This provides multiple limits and prevents the rotating shaft 23 from shaking when rotating because it is only subjected to the force of the synchronous belt 24 from below, thus increasing stability. Furthermore, by using the motor 14 to drive the mixing main shaft 15 and the scraper 36 of the rotating shaft 23 to rotate via the synchronous belt 24, it not only provides a guiding function for groundwater treatment but also prevents the filter screen 34 from clogging. Since the same motor 14 is used for the mixing main shaft 15, it also has a certain energy-saving effect, making it quite practical.

[0034] The first storage slot 25 is formed through the inside of the pipe 18. An acrylic observation window 26 is located inside the first storage slot 25 and is fixedly installed with the first storage slot 25. The second storage slot 27 is formed through the side wall of the first storage slot 25. Two guide slots 28 are formed on the inner wall of the second storage slot 27. A concave limiting slot 29 is formed between the guide slots 28 and is located below the first storage slot 25. Two guide blocks 31 are both located between the guide slots 28 and are slidably installed with the guide slots 28. A U-shaped block 32 is located between the guide blocks 31 and is fixedly installed with the guide blocks 31. The U-shaped block 32 is slidably installed with the second storage slot 27. A limiting base plate 33 is located in the concave limiting slot. Inside the groove 29, the limiting base plate 33 is slidably installed with the concave limiting groove 29. By pulling the U-shaped block 32 upward, the U-shaped block 32 can drive the guide block 31, the limiting base plate 33, and the filter screen 34 to move within the guide groove 28 and the second storage groove 27, thereby allowing the filter screen 34 to be removed as a whole. This facilitates the use of a high-pressure water gun to rinse the filter screen 34, the underground water treatment tank 11, and the inside of the pipe 18. At the same time, by setting the limiting base plate 33 and the guide block 31, it can be ensured that the filter screen 34 is kept in a parallel state when it is placed, avoiding the filter screen 34 being tilted when placed, which would cause some flocculent to flow out from the holes at the tilted part of the filter screen 34 when intercepting flocculent later, thus improving portability.

[0035] The filter screen 34 is located at the upper end of the limiting base plate 33 and is fixedly installed thereon. One end of the filter screen 34 is arc-shaped. Each guide plate 35 is located on the side frame of the filter screen 34 and is fixedly installed thereon. Each scraper plate 36 is located on the circumferential surface of the rotating shaft 23 and is fixedly installed thereon. The end portion of each scraper plate 36 is located between the guide plates 35, and each scraper plate 36 is adapted to the guide plate 35 and the filter screen 34. By using the motor 14 to drive the mixing shaft 15 and the scraper 36 of the rotating shaft 23 to rotate, not only can the groundwater be initially flocculated and the filter screen 34 be prevented from clogging, but also when the electrically controlled valve 17 is raised, the centrifugal force generated by the rotation of the mixing shaft 15 and the scraper 36 of the rotating shaft 23 can provide a dual guiding effect on the water flow when the groundwater is transported to the pipe 18 and the filter screen 34, making the water flow more uniform and increasing the stability of groundwater treatment.

[0036] Working principle:

[0037] The first step is to first transport the groundwater to be treated into the groundwater treatment tank 11 through the inlet 13. After the transport is completed, the staff can add an appropriate amount of flocculant into the groundwater treatment tank 11. Then, the staff can turn on the motor 14 through the controller 12, so that the output shaft of the motor 14 drives the mixing shaft 15. At this time, the mixing shaft 15 will rotate inside the groundwater treatment tank 11, thereby making the flocculant and groundwater in the groundwater treatment tank 11 fully mixed. The flocculant will react chemically with the suspended matter in the water to form flocs. These flocs are larger particles formed by the aggregation of small particles, resulting in large and numerous clusters inside the groundwater treatment tank 11. However, due to the mixing of the mixing shaft 15, the blades of the mixing shaft 15 will also break up some of the already flocculed clusters inside the groundwater treatment tank 11, so that the larger flocs settle at the bottom of the groundwater treatment tank 11, and the smaller clusters float inside the groundwater treatment tank 11 due to the centrifugal force of the mixing shaft 15.

[0038] The second step involves raising the electric valve 17 via the controller 12 after flocculation, exposing the outlet tank 16. Groundwater carrying some of the floating flocculent material enters the pipe 18, where it is intercepted by the filter screen 34. Simultaneously, since the motor 14 remains running, it drives the rotating shaft 23 and its rotating ring 22 via the synchronous belt 24, causing them to slide within the circular groove 19 and annular groove 21 respectively. This causes the rotating shaft 23 to rotate the scraper plate 36 inside the pipe 18. Because the water flows through the holes in the filter screen 34, some flocculent material is carried into the guide plates 35 during groundwater discharge. The rotation of the scraper plate 36 then scrapes away the flocculent material between each guide plate 35, preventing blockage of the filter screen 34. The water then flows through the pipe 18 into the next filtration and disinfection step.

[0039] The third step is to clean the filter screen 34. First, observe the acrylic observation window 26 on the first storage slot 25. Observe that the scraper plate 36 is not aligned with the acrylic observation window 26. Then, pull the U-shaped block 32 upwards. This will cause the U-shaped block 32 to move the guide block 31, the limiting base plate 33, and the filter screen 34 within the guide slot 28 and the second storage slot 27 until the filter screen 34 is completely removed. After the filter screen 34 is removed, the staff can use a high-pressure water gun to clean the inside of the filter screen 34. After cleaning, the guide block 31 can be aligned with the guide slot 28 again, and the U-shaped block 32, the limiting base plate 33, and the filter screen 34 can be inserted until the limiting base plate 33 is located in the concave limiting slot 29. At this point, the maintenance of the filter screen 34 is complete.
