Description

Technical Field

[0001] The invention relates to the technical field of groundwater purification, in particular to a multi-stage groundwater purification device in sandy areas and a purification method thereof. Background Art

[0002] In some remote mountain villages, there is no tap water, and most people use groundwater as drinking water. However, the groundwater contains a lot of sand and cannot be drunk directly. The water needs to be pumped out and clarified before use, which causes some faucets and solar energy to not work properly.

[0003] Generally, when filtering groundwater, processed water needs to be injected above the filter element inside the purification device. By continuously injecting groundwater into the purification device, the water pressure above the filter element inside the purification device is increased, thereby improving the efficiency of groundwater filtering through the filter element inside the purification device. However, when the water pressure above the filter element inside the purification device is too high, the filter element may be subjected to excessive pressure and may be broken or damaged, thereby reducing the filtering effect of the filter element. Moreover, when the interior of the purification device is subjected to high water pressure for a long time, the wear of internal parts of the purification device may be accelerated, resulting in a shortened equipment life and requiring more frequent maintenance and replacement, thereby increasing the maintenance cost and use cost of the purification device.

[0016] A multi-stage groundwater purification device for sandy areas and a purification method thereof, comprising the following steps:

[0017] S1: Connect the water inlet to the groundwater input pipe, continuously inject water into the main body, and filter the water through the filter cartridge inside the main body;

[0018] S2: When the water pressure inside the main body suddenly increases due to various factors, after the space above the filter cartridge inside the main body is filled with groundwater, the groundwater pushes the two piston rods to slide outward inside the pressure reducing tubes, compressing the pressure springs, and the groundwater enters the inside of the two pressure reducing tubes;

[0019] S3: When the water pressure inside the main body pushes the piston rod to move inside the pressure reducing tube, the lifting bar will rotate at the end away from the piston rod, so that the angle between the lifting bar and the piston rod becomes smaller, thereby pulling the sliding frame to slide and rise inside the rising slide groove, thereby driving the reinforcement frame to rise;

[0020] S4: When the water pressure inside the main body continues to increase, the piston head of the piston rod close to one end of the main body will be pushed to a position inside the pressure reducing tube away from one end of the main body, so that the outer water pipe is connected with the pressure reducing tube and the inside of the main body through the water outlet hole, so that water enters between the outer water pipe and the pressure reducing tube, and then pushes the outer cavity piston ring to slide between the outer water pipe and the pressure reducing tube to one side of the main body, compressing the pressure spring, thereby further increasing the buffering of the water pressure inside the main body, and quickly discharging excess water from the main body without increasing the water pressure.

[0021] The present invention has the following beneficial effects:

[0022] (1) The present invention is connected to the groundwater input pipe through the water inlet, and continuously injects water into the main body, so that the water passes through the filter cartridge inside the main body for filtering. The filtered groundwater falls to the bottom of the main body and flows out from the water outlet. When the water pressure inside the main body suddenly increases due to various factors, after the space above the filter cartridge inside the main body is filled with groundwater, the groundwater pushes the two piston rods to slide outward inside the pressure reducing tubes respectively, compressing the pressure spring. The groundwater enters the inside of the two pressure reducing tubes, increasing the water storage space above the filter cartridge inside the main body, thereby reducing the water pressure of the groundwater inside the main body, reducing the probability of the filter cartridge inside the pressure reducing tube being broken or damaged due to excessive pressure, improving the filtering effect of the filter cartridge, reducing the wear of the internal parts of the main body and the pressure reducing tube when the interior of the main body is subjected to high water pressure for a long time, thereby increasing the service life of the device, reducing the maintenance and replacement frequency of the device, and thus reducing the maintenance cost and use cost of the purification device.

[0023] When the water pressure inside the main body of the present invention pushes the piston rod to move inside the pressure reducing tube, the lifting bar will rotate at the end away from the piston rod, so that the angle between the lifting bar and the piston rod becomes smaller, thereby pulling the sliding frame to slide and rise inside the ascending slide groove, thereby driving the reinforcement frame to rise, so that the reinforcement frame and the outer wall of the closed frame are against each other, and the tightness of the connection between the closed frame and the main body is increased. When the water pressure inside the main body continues to increase, the piston head of the piston rod close to one end of the main body will be pushed to a position inside the pressure reducing tube away from the end of the main body, so that the outer water pipe is connected with the pressure reducing tube and the inside of the main body through the water outlet hole, so that water enters between the outer water pipe and the pressure reducing tube, and then pushes the outer cavity piston ring to slide between the outer water pipe and the pressure reducing tube toward one side of the main body, compressing the pressure-increasing spring, thereby further increasing the buffering of the water pressure inside the main body, replacing the pressure reducing valve, and quickly discharging excess water from the main body without increasing the water pressure, reducing unnecessary waste of groundwater, and keeping the water pressure inside the main body within a specified range.

[0024] (3) During the sliding process of the outer cavity piston ring of the present invention, the connecting extension frame will be driven to slide synchronously inside the push slide hole, so that the connecting pull bar will rotate on the connecting extension frame, and the angle between the connecting pull bar and the connecting extension frame will gradually decrease with the movement amplitude of the outer cavity piston ring, thereby driving the sliding plate to slide downward on the slide rod, and while the downward pressing extension bar is descending, the lower pressing bar will be pressed downward, so that the end of the lower pressing bar away from the downward pressing extension bar will rotate on the rotating connecting frame, so that the lifting slide hole bar will be tilted, and the limit frame can be used to lift the lifting slide hole bar. By sliding, the limit frame can be pulled to slide upward inside the jack, so that the limit frame gradually separates from the sealing ring. When the water pressure inside the main body exceeds the specified range value, the limit frame will be completely separated from the sealing ring. After the sealing ring loses the limiting force of the limit frame, it will separate from the blockage of the pressure reducing water outlet hole, so that the water between the pressure reducing pipe and the external water pipe will be sprayed out through the pressure reducing water outlet hole, which can quickly relieve the pressure inside the main body, and the water sprayed from the side can increase the distance of groundwater spraying, thereby serving as a reminder to the staff, thereby improving the practicability of the device.

Three push sliding holes 204 are arranged on the outer wall of the external water pipe 203 at one end close to the main body 1. The external water pipe 203 is fixedly connected with a sliding rod 205. The external water pipe 203 is fixedly connected with an extension plate 206 at one end away from the push sliding hole 204. The top of the extension plate 206 is fixedly connected with a rotating connecting frame 207 at one end close to the sliding rod 205. , a plug hole 208 is formed through the end of the top of the extension plate 206 away from the rotating connecting frame 207, and a pressure-reducing water outlet hole 209 is formed on the side of the outer water pipe 203 away from the main body 1, which will push the piston head of the piston rod 401 close to one end of the main body 1 to a position inside the pressure-reducing pipe 201 away from one end of the main body 1, so that the outer water pipe 203 is connected with the pressure-reducing pipe 201 and the inside of the main body 1 through the water outlet hole 202, so that water enters between the outer water pipe 203 and the pressure-reducing pipe 201, and then pushes the outer cavity piston ring 501 to slide between the outer water pipe 203 and the pressure-reducing pipe 201 toward one side of the main body 1, compressing the pressure-increasing spring 504, thereby further increasing the buffering of the water pressure inside the main body 1, replacing the pressure-reducing valve, and quickly discharging excess water from the main body 1 without increasing the water pressure, and can keep the water pressure inside the main body 1 within a specified range;

The groundwater enters the inside of the two pressure reducing tubes 201, increasing the water storage space above the filter cartridge inside the main body 1, thereby reducing the water pressure of the groundwater inside the main body 1. The reinforcement mechanism 4 also includes a pulling bar 403, which is rotatably connected to the piston rod The end of 401 away from the piston head and the end of the lifting bar 403 away from the piston rod 401 are fixedly connected with a sliding frame 404, and the sliding frame 404 is slidably connected to the inside of the rising slide groove 103. The outer walls of the two sliding frames 404 are fixedly connected with a reinforcement frame 405, and the side of the reinforcement frame 405 close to the main body 1 is against the outer wall of the closed frame 302. When the water pressure inside the main body 1 pushes the piston rod 401 to move inside the pressure reducing tube 201, the lifting bar 403 will rotate at the end away from the piston rod 401, so that the angle between the lifting bar 403 and the piston rod 401 becomes smaller, so that the sliding frame 404 can be pulled to slide and rise inside the rising slide groove 103, thereby driving the reinforcement frame 405 to rise, so that the reinforcement frame 405 is against the outer wall of the closed frame 302, and the tightness of the connection between the closed frame 302 and the main body 1 is increased;

[0042] The outer wall of the main body 1 is provided with a filter element installation port 102, and the upper and lower ends of the outer wall of the main body 1 located at the filter element installation port 102 are provided with threaded connection grooves, and the end of the outer wall of the side plate 101 away from the pressure reducing pipe 201 is provided with an ascending chute 103, and the bottom of the main body 1 is fixedly connected with a support frame 104, and the top of the main body 1 is fixedly connected with a water inlet 105, and the bottom of the main body 1 is fixedly connected with a water outlet 106, which is connected to the groundwater input pipe through the water inlet 105, and water is continuously injected into the inside of the main body 1, so that the water passes through the filter cartridge 301 inside the main body 1 for filtering, and the filtered groundwater falls to the bottom of the main body 1 and flows out from the water outlet 106;

[0043] A filter element mechanism 3 is arranged inside the filter element installation opening 102, and the filter element mechanism 3 includes a filter element barrel 301, and the filter element barrel 301 is inserted into the filter element installation opening 102. A closed frame 302 is fixedly connected to the outer wall of the filter element barrel 301, and threaded connection hole blocks 304 are fixedly connected to the two positions of the outer wall of the closed frame 302 corresponding to the two threaded connection grooves, and two handles 303 are fixedly connected to the outer wall of the closed frame 302;

[0044] The outer wall of the outer water pipe 203 is provided with an outlet mechanism 5, and the outlet mechanism 5 includes an outer cavity piston ring 501, and the outer cavity piston ring 501 is slidably connected between the outer water pipe 203 and the pressure reducing pipe 201, and the outer wall of the outer cavity piston ring 501 is fixedly connected with three connecting extension frames 502 at one end close to the main body 1, and the three connecting extension frames 502 are respectively slidably connected with the inside of the three push sliding holes 204, and the three connecting extension frames 502 are rotatably connected with the connecting pull strips 503 inside, and the connecting extension frames 502 are fixedly connected with the side of the outer water pipe 203 close to the main body 1. The pressure spring 504 is fixedly connected, and the connecting pull strip 503 is far away One end of the connecting extension frame 502 is rotatably connected with a sliding sheet 505, and the sliding sheet 505 is slidably connected to the outer wall of the sliding rod 205. The side of the sliding sheet 505 away from the connecting pull bar 503 is fixedly connected with a downward pressing extension bar 506. The outer wall of the rotating connecting frame 207 is rotatably connected with a downward pressing bar 507.

The side is plugged with a blocking ring 510, and the limiting frame 509 is against the outer wall of the blocking ring 510. During the sliding process of the outer cavity piston ring 501, it will drive the connecting extension frame 502 to slide synchronously inside the push slide hole 204, so that the connecting pull bar 503 rotates on the connecting extension frame 502, so that the angle between the connecting pull bar 503 and the connecting extension frame 502 gradually decreases with the movement of the outer cavity piston ring 501, thereby driving the sliding sheet 505 to slide down on the slide rod 205, and while the downward extension bar 506 is lowered, the lower pressing bar 507 is pressed down, so that the lower pressing bar 507 is away from the lower pressing extension bar One end of the extension bar 506 rotates on the rotating connecting frame 207, so that the lifting sliding hole bar 508 is tilted, and the lifting sliding hole bar 508 can be slid on the limiting frame 509, and the limiting frame 509 can be pulled to slide on the inner line of the jack 208, so that the limiting frame 509 gradually separates from the blocking ring 510. When the water pressure inside the main body 1 exceeds the specified range value, the limiting frame 509 will be completely separated from the blocking ring 510. After the blocking ring 510 loses the limiting force of the limiting frame 509, it will separate from the blockage of the pressure reducing water outlet 209, so that the water between the pressure reducing pipe 201 and the external water pipe 203 is sprayed out through the pressure reducing water outlet 209.

[0045] When in use, the water inlet 105 is connected to the groundwater input pipe, and water is continuously injected into the main body 1, so that the water passes through the filter cartridge 301 inside the main body 1 for filtering, and the filtered groundwater falls to the bottom of the main body 1 and flows out from the water outlet 106. When the water pressure inside the main body 1 suddenly increases due to various factors, after the space above the filter cartridge 301 inside the main body 1 is filled with groundwater, the groundwater will push the two piston rods 401 to slide outward inside the pressure reducing tube 201 respectively, and squeeze the pressure spring 402. The groundwater enters the inside of the two pressure reducing tubes 201, increasing the water storage space above the filter element inside the main body 1, thereby reducing the water pressure of the groundwater inside the main body 1, and reducing the probability of the filter element inside the pressure reducing tube 201 being broken or damaged due to excessive pressure.

When the water pressure inside the main body 1 continues to increase, the piston rod 401 will be close to the piston at one end of the main body 1. The head is pushed to a position inside the pressure reducing tube 201 away from one end of the main body 1, so that the outer water tube 203 is connected with the pressure reducing tube 201 and the inside of the main body 1 through the water outlet 202, so that water enters between the outer water tube 203 and the pressure reducing tube 201, and then the outer cavity piston ring 501 is pushed to slide between the outer water tube 203 and the pressure reducing tube 201 toward one side of the main body 1 to compress the pressure spring 504, thereby further increasing the buffering of the water pressure inside the main body 1, replacing the pressure reducing valve, and quickly discharging the excess water from the main body 1 without increasing the water pressure, and can keep the water pressure inside the main body 1 within a specified range;

When the water pressure inside the main body 1 exceeds the specified range value, the limit frame 509 will be completely separated from the blocking ring 510. After the blocking ring 510 loses the limiting force of the limit frame 509, it will separate from the blockage of the pressure reducing water outlet 209, so that the water between the pressure reducing pipe 201 and the external water pipe 203 will be sprayed out through the pressure reducing water outlet 209, which can quickly relieve the pressure inside the main body 1, and the water sprayed from the side can increase the distance of the groundwater spraying, so as to serve as a reminder to the staff.

6. A method for purifying groundwater in a sandy area using a multi-stage groundwater purification device, using the multi-stage groundwater purification device in a sandy area as claimed in claim 5, characterized in that: The following steps are involved: S1: Connecting the water inlet (105) to the groundwater input pipe, continuously injecting water into the main body (1), so that the water passes through the filter cartridge (301) inside the main body (1) for filtration; S2: When the water pressure inside the main body (1) suddenly increases due to various factors, after the space above the filter cartridge (301) inside the main body (1) is filled with groundwater, the groundwater pushes the two piston rods (401) to slide outward inside the pressure reducing tubes (201) respectively, compressing the pressure springs (402), and the groundwater enters the inside of the two pressure reducing tubes (201); S3: When the water pressure inside the main body (1) pushes the piston rod (401) to move inside the pressure reducing tube (201), the lifting bar (403) is caused to rotate at the end away from the piston rod (401), so that the angle between the lifting bar (403) and the piston rod (401) becomes smaller, thereby pulling the sliding frame (404) to slide and rise inside the rising slide groove (103), thereby driving the reinforcement frame (405) to rise; S4: When the water pressure inside the main body (1) continues to increase, the piston head of the piston rod (401) close to one end of the main body (1) is pushed to a position inside the pressure reducing tube (201) away from one end of the main body (1), so that the outer water tube (203) is connected to the pressure reducing tube (201) and the inside of the main body (1) through the water outlet hole (202), so that water enters between the outer water tube (203) and the pressure reducing tube (201), and then pushes the outer cavity piston ring (501) to slide between the outer water tube (203) and the pressure reducing tube (201) toward one side of the main body (1), compressing the pressure spring (504), thereby further increasing the buffering of the water pressure inside the main body (1), and quickly discharging excess water from the main body (1) without increasing the water pressure.
