Description

A water treatment device for preventing and controlling groundwater pollution

Technical Field

The present invention belongs to the technical field of water treatment, and more specifically, particularly relates to a water treatment device for preventing and controlling groundwater pollution.

Background technique

Groundwater refers to water that exists in underground rock formations or soil pores in nature. These water sources usually come from rainwater infiltrating into the ground or surface water infiltrating into the underground layer. Groundwater plays an important role in the water cycle on the earth. 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 flocculate, filter, disinfect and other treatments on the contaminated groundwater to ensure that the water quality meets hygiene standards, thereby protecting people's health and quality of life.

When the existing water treatment device treats groundwater, since the groundwater will carry some impurities such as mud and sand during its flow, flocculation is required. In order to improve the flocculation efficiency, the existing water treatment device usually adds a mixing spindle at the center of the water treatment tank to improve the reaction efficiency of the flocculant and groundwater. However, the rotation of the mixing spindle will have an effect of breaking up the partially flocculated clusters, so that when the subsequent groundwater is transported, the water flow is easy to carry the clusters and get stuck in the filter, thereby affecting the transportation efficiency of the groundwater. The practicality needs to be improved.

Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a water treatment device for groundwater pollution prevention and control is provided, in order to achieve a more practical purpose.

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

In the present invention, by turning on the motor, not only can the groundwater inside the groundwater treatment pool be flocculated and fully mixed with the groundwater for flocculation, but the rotation of the motor will drive the rotating shaft to rotate in the circular groove through the synchronous belt, so that the rotating shaft drives the scraper plate to rotate inside the pipe.

In the present invention, by using a motor to drive the mixing main shaft and the scraper plate of the rotating shaft to rotate, not only can the preliminary flocculation of groundwater and the prevention of filter screen clogging be completed, but also when the electric control valve is raised, a centrifugal force is generated when the mixing main shaft and the scraper plate of the rotating shaft rotate, thereby providing a double 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 when treating the groundwater;

In the present invention, by using a motor to drive the mixing main shaft and the scraper plate of the rotating shaft to rotate with a synchronous belt, it can not only provide a guiding role for groundwater treatment, but also have an anti-clogging effect on the filter screen. At the same time, because the motor used is the same as the mixing main shaft, it can also achieve a certain energy-saving effect, which is more practical.

In the present invention, by providing a rotating ring and an annular groove, the synchronous belt can drive the rotating ring on the rotating shaft to slide in the circular groove and the annular groove when the rotating shaft is driven to rotate, thereby providing multiple position limits, avoiding the shaking of the rotating shaft when the rotating shaft is rotated because the rotating shaft is only subjected to the force of the synchronous belt rotation at the bottom, thereby increasing stability;

In the present invention, by pulling the U-shaped block upwards, the U-shaped block can drive the guide block, the limiting bottom plate and the filter to move in the guide groove and the second storage groove, so that the filter can be taken out as a whole, and it is convenient for the staff to use a high-pressure water gun to flush the filter and the inside of the groundwater treatment tank and the pipeline. At the same time, by setting the limiting bottom plate and the guidance of the guide block, it can be ensured that the filter is kept in a parallel state, and the filter is prevented from being tilted when placed, which causes part of the floccules to flow out from the holes at the tilted part of the filter when the floccules are intercepted later, thereby improving portability.

Detailed ways

The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Referring to FIGS. 1 to 9 , the present invention provides a water treatment device for preventing and controlling groundwater pollution, including a groundwater treatment pool 11, a controller 12 is fixedly mounted on the side wall of the groundwater treatment pool 11, and a water inlet 13 is provided on the side wall of the groundwater treatment pool 11 away from the controller 12;

An anti-blocking mechanism is fixedly installed at the lower end of the groundwater treatment tank 11;

The anti-blocking mechanism includes a motor 14, a mixing spindle 15 is fixedly installed inside the groundwater treatment tank 11, and the mixing spindle 15 is located at the center of the groundwater treatment tank 11. The output shaft of the motor 14 is fixedly installed with the mixing spindle 15. The anti-blocking mechanism also includes a pipeline 18, a circular groove 19, an annular groove 21, a rotating ring 22, a rotating shaft 23, a synchronous belt 24, a first storage groove 25, an acrylic observation window 26, a second storage groove 27, a guide groove 28, a concave limit groove 29, a guide block 31, a U-shaped block 32, a limit bottom plate 33, a filter screen 34, a guide plate 35 and a scraper plate 36. By turning on the motor 14, not only can the groundwater inside the groundwater treatment tank 11 be flocculated and fully mixed with the groundwater, but also the groundwater inside the groundwater treatment tank 11 can be flocculated and fully mixed with the groundwater. The water is fully mixed for flocculation, and the rotation of the motor 14 will drive the rotating shaft 23 to rotate in the circular groove 19 through the synchronous belt 24, so that the rotating shaft 23 drives the scraper plate 36 to rotate inside the pipe 18. Since the water flows out through the holes of the filter 34, when the groundwater is subsequently discharged, the groundwater is likely to carry some floating flocculants and be blocked in the holes of the filter 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 avoid the clusters of flocculants blocking the holes of the filter 34 and affecting the transportation of the groundwater flow, thereby improving the treatment efficiency.

A water outlet trough 16 is provided inside the underground water treatment pool 11, an electric control valve 17 is provided inside the water outlet trough 16, a pipe 18 is located on the surface of the water outlet trough 16, the pipe 18 is fixedly installed with the water outlet trough 16, two circular grooves 19 are provided inside the pipe 18, the two circular grooves 19 are parallel to each other, two annular grooves 21 are provided on the inner wall of the circular groove 19, two rotating rings 22 are provided inside the annular grooves 21, the two rotating rings 22 are rotatably installed with the annular grooves 21, a rotating shaft 23 is provided between the rotating rings 22, the rotating shaft 23 is fixedly installed with the rotating rings 22, the rotating shaft 23 is rotatably installed with the circular groove 19, and a part of the rotating shaft 23 is exposed below the pipe 18, a synchronous belt 24 is provided 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 Installation, by setting the rotating ring 22 and the annular groove 21, the synchronous belt 24 can drive the rotating ring 22 on the rotating shaft 23 to slide in the circular groove 19 and the annular groove 21 when the rotating shaft 23 is driven to rotate, thereby providing multiple limits to avoid the rotating shaft 23 shaking when rotating because the rotating shaft 23 is only subjected to the force of the rotating synchronous belt 24 at the bottom, thereby increasing stability, and by using the motor 14 to use the synchronous belt 24 to drive the mixing main shaft 15 and the scraper plate 36 of the rotating shaft 23 to rotate, it can not only provide a guide for groundwater treatment, but also have an anti-blocking effect on the filter screen 34. At the same time, since the same motor 14 is used as the mixing main shaft 15, it can also have a certain energy-saving effect, which is more practical.

The first storage groove 25 is penetrated and opened inside the pipe 18, the acrylic observation window 26 is located inside the first storage groove 25, and the acrylic observation window 26 is fixedly installed with the first storage groove 25. The second storage groove 27 is penetrated and opened on the side wall of the first storage groove 25, and two guide grooves 28 are both opened on the inner wall of the second storage groove 27. The concave limiting groove 29 is opened between the guide grooves 28, and the concave limiting groove 29 is located below the first storage groove 25. The two guide blocks 31 are both located between the guide grooves 28, and the two guide blocks 31 are both slidably installed with the guide grooves 28. The U-shaped block 32 is located between the guide blocks 31, and the U-shaped block 32 is fixedly installed with the guide block 31. The U-shaped block 32 is slidably installed with the second storage groove 27, and the limiting bottom plate 33 is located at the concave limiting bottom plate 33. Inside the groove 29, the limiting bottom 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 bottom plate 33 and the filter 34 to move in the guide groove 28 and the second storage groove 27, so that the filter 34 can be taken out as a whole, and it is convenient for the staff to use a high-pressure water gun to flush the filter 34 and the inside of the groundwater treatment tank 11 and the pipeline 18. At the same time, by setting the limiting bottom plate 33 and the guiding of the guide block 31, it can be ensured that the filter 34 remains in a parallel state when prevented, and the filter 34 is prevented from being tilted when placed, which causes part of the flocculants to flow out from the holes at the tilt of the filter 34 when the flocculants are intercepted later, thereby improving portability.

The filter screen 34 is located at the upper end of the limiting bottom plate 33, and the filter screen 34 is fixedly installed with the limiting bottom plate 33. The end of one side of the filter screen 34 is in an arc shape. Each guide plate 35 is located on the side frame of the filter screen 34, and each guide plate 35 is fixedly installed with the filter screen 34. Each scraper plate 36 is located on the circumferential surface of the rotating shaft 23, and each scraper plate 36 is fixedly installed with the rotating shaft 23. 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 main shaft 15 and the scraper plate 36 of the rotating shaft 23 to rotate, not only can the preliminary flocculation of groundwater be completed and the filter screen 34 be prevented from being blocked, but also when the electric control valve 17 is raised, a centrifugal force will be generated when the mixing main shaft 15 and the scraper plate 36 of the rotating shaft 23 rotate, thereby providing a double guiding effect on the water flow when the groundwater is transported to the pipeline 18 and the filter screen 34, making the water flow more uniform and increasing the stability when treating groundwater.

working principle:

The first step is that when in use, the groundwater to be treated can be first transported to the groundwater treatment tank 11 through the water inlet 13. After the transport is completed, the staff can add an appropriate amount of flocculant to 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 spindle 15. At this time, the mixing spindle 15 will rotate inside the groundwater treatment tank 11, so that the flocculant inside the groundwater treatment tank 11 is fully mixed with the groundwater. The flocculant will react chemically with the suspended matter in the water to form floccules. These floccules are larger particles formed by the aggregation of small particles, so that there are larger and more clusters inside the groundwater treatment tank 11. However, due to the mixing of the mixing spindle 15, the blades of the mixing spindle 15 will also break up some of the flocculated clusters inside the groundwater treatment tank 11, so that the larger floccules are precipitated at the bottom of the groundwater treatment tank 11, and the smaller clusters will float inside the groundwater treatment tank 11 with the centrifugal force of the mixing spindle 15;

In the second step, after the flocculation is completed, the staff can control the electric control valve 17 to rise by the controller 12, so that the water outlet trough 16 is in a naked state. At this time, the groundwater will carry some floating floccules into the pipe 18, and the floccules will be intercepted by the filter 34. At the same time, because the motor 14 is not turned off, the motor 14 will drive the rotating shaft 23 and the rotating ring 22 on the rotating shaft 23 to slide in the circular groove 19 and the annular groove 21 respectively through the synchronous belt 24, so that the rotating shaft 23 drives the scraper plate 36 to rotate inside the pipe 18. Since the water flow flows in through the holes of the filter 34, when the groundwater is discharged, the groundwater carries some floccules into the guide plates 35. At this time, the rotation of the scraper plate 36 will drive the floccules between each guide plate 35 to scrape, so as to prevent the floccules from being blocked in the holes of the filter 34. Then the water flow will flow into the next filtering and disinfection step through the pipe 18;

In the third step, when the filter 34 needs to be cleaned, the acrylic observation window 26 on the first storage groove 25 can be observed first. It is necessary to observe that the scraper plate 36 is not in contact with one side of the acrylic observation window 26. Then the U-shaped block 32 can be directly pulled upward, so that the U-shaped block 32 drives the guide block 31, the limiting bottom plate 33 and the filter 34 to move in the guide groove 28 and the second storage groove 27 until the filter 34 is taken out as a whole. When the filter 34 is taken out, the staff can use a high-pressure water gun to clean the inside of the filter 34. After the cleaning is completed, the guide block 31 can be aligned with the guide groove 28 again to insert the U-shaped block 32, the limiting bottom plate 33 and the filter 34 as a whole until the limiting bottom plate 33 is located in the concave limiting groove 29. At this time, the maintenance of the filter 34 is completed.

Many modifications and variations will be apparent to those of ordinary skill in the art.
