Description

Technical Field

[0001] The present invention relates to the technical field of water and sand separation, and particularly to an automatic treatment device for leaking well water and sand. Background Art

[0002] Due to factors such as geological conditions, well structures, and long-term water flow scouring, sand grains will seep into well water. During the process of pumping and using well water, the mixing of sand grains is a common and troublesome problem. These sand grains are easily carried by the water flow into the water pump and subsequent water treatment systems during the pumping process, causing wear to key components such as the impeller and bearing of the water pump, shortening the service life of the equipment, and increasing maintenance costs. Currently, although there are some devices for separating sand grains from well water on the market, most of them have the following deficiencies: The filter screen for intercepting sand grains is easily blocked by sand grains after long-term use, affecting the water flow through, reducing the conveying efficiency, and cleaning the filter screen requires manual operation, which is time-consuming and laborious. Moreover, existing devices mostly focus on sand grain filtration during the pumping process, while ignoring the collection of sand grains deposited at the bottom of the well, resulting in the continuous accumulation of sand grains at the bottom of the well and the gradual reduction of the well capacity. Therefore, there is a need to provide an automatic treatment device for leaking well water and sand, aiming to solve or alleviate the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic treatment device for leaking well water and sand, aiming to solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An automatic treatment device for leaking well water and sand, including a treatment cylinder body and a water pump, the treatment cylinder body is connected to the water pump. Inside the treatment cylinder body, a fixed ring, a lifting disk, and a filter disk are sequentially arranged from top to bottom. The fixed ring and the filter disk are both fixedly connected to the inner wall of the treatment cylinder body. An ascending and descending cylinder is arranged in the fixed ring, and the outer side surface of the ascending and descending cylinder is slidably and cooperatively connected to the inner side surface of the fixed ring. A plurality of water passing grooves are arranged on the side surface of the ascending and descending cylinder, and the cross-sectional area of the water passing grooves gradually increases from top to bottom. At least one side surface of the water passing groove is an inclined surface. The ascending and descending cylinder is connected to the lifting disk through a connecting column. A plurality of cleaning needles are installed on the bottom surface of the lifting disk, and the cleaning needles are used to clean the mesh holes on the filter disk. The working power of the water pump can change periodically, so that the ascending and descending cylinder performs reciprocating ascending and descending movements. A sand grain collection mechanism is also arranged at the bottom of the treatment cylinder body, and the reciprocating ascending and descending movement of the ascending and descending cylinder will cause the sand grain collection mechanism to work synchronously.

[0005] As a further solution of the present invention, the bottom of the treatment cylinder body is sealed, and the collected and intercepted sand grains will deposit at the bottom of the treatment cylinder body. An inclined water inlet pipe is connected to the side of the treatment cylinder body. The inclined water inlet pipe is arranged obliquely, the outer port of the inclined water inlet pipe is higher than the inner port of the inclined water inlet pipe, and a set distance is arranged between the inner port of the inclined water inlet pipe and the bottom of the treatment cylinder body.

[0006] As a further solution of the present invention, the sand grain collecting mechanism includes a plurality of threaded shafts and rotating disks, and the threaded shafts and the rotating disks correspond one by one. The threaded shafts are connected to the lifting disks. The threaded shafts are arranged outside the treatment cylinder body. An installation frame is fixedly connected to the outer side surface of the treatment cylinder body. The rotating disks are rotatably installed on the installation frame. Threaded holes are arranged on the rotating disks. The threaded shafts are in mating connection with the corresponding threaded holes. A stirring assembly is connected to the rotating disks.

[0007] As a further solution of the present invention, the treatment cylinder body and the threaded shafts are both arranged vertically, the fixed ring, the lifting disk and the filter disk are all arranged horizontally. The stirring assembly includes a stirring shaft and stirring blades. The stirring shaft is fixedly connected to the bottom surface of the rotating disk. A plurality of the stirring blades are connected to the stirring shaft.

[0008] As a further solution of the present invention, the threaded shafts are connected to the lifting disks through horizontal plates and vertical columns. The vertical columns are fixedly connected to the lifting disks and penetrate through the filter disk. One end of the horizontal plate is connected to the vertical column, and the other end of the horizontal plate is connected to the threaded shaft. A through groove one is arranged on the side surface of the treatment cylinder body. The horizontal plate passes through the through groove one.

[0009] As a further solution of the present invention, a guide plate is connected to the surface of the lifting cylinder body. Guide through holes are arranged on the guide plate. A guide shaft is connected to the top surface of the fixed ring. The guide shaft penetrates through the guide through holes and is in sliding fit connection with the inner walls of the guide through holes. A limit block is connected to the top end of the guide shaft. A plurality of through grooves two are arranged on the surface of the lifting disk.

[0010] As a further solution of the present invention, a connector is arranged at the top end of the treatment cylinder body. The connector is connected to the water inlet of the water pump through a water pipe.

[0011] As a further solution of the present invention, a frequency converter is installed in the water pump. The frequency converter is connected to the water pump motor; when the working power of the water pump changes periodically, the cleaning needle will perform a reciprocating lifting motion. The diameter of the cleaning needle is smaller than the diameter of the mesh holes on the filter disk.

[0012] In summary, the beneficial effects of the present invention are:

[0013] Through the settings of the lifting cylinder, water passing groove, fixed ring, lifting disc, filter disc, cleaning needle and sand collection mechanism. When the working power of the water pump changes periodically, the lifting cylinder will perform reciprocating lifting motion, and then the cleaning needle will also perform reciprocating lifting motion to realize the automatic cleaning of the meshes on the filter disc. At the same time, the reciprocating lifting motion of the lifting cylinder will cause the sand collection mechanism to work synchronously, realizing the collection of sand grains at the bottom of the well, reducing the sediment amount of sand grains at the bottom of the water well and slowing down the sedimentation speed of sand grains.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] Please refer to Figures 1 to 6, an automatic treatment device for leaking well water sand provided by an embodiment of the present invention includes a treatment cylinder body 1 and a water pump 4. A frequency converter is installed in the water pump 4, and the frequency converter is connected to a water pump motor. The working power of the water pump 4 can be made to change periodically through the frequency converter. The treatment cylinder body 1 is connected to the water pump 4. Inside the treatment cylinder body 1, a fixed ring 10, a lifting disc 17, and a filtering disc 20 are sequentially arranged from top to bottom. The filtering disc 20 is used to intercept sand grains in the well water. Both the fixed ring 10 and the filtering disc 20 are fixedly connected to the inner wall of the treatment cylinder body 1. A lifting cylinder 11 is arranged in the fixed ring 10. The outer side surface of the lifting cylinder 11 is slidably and cooperatively connected to the inner side surface of the fixed ring 10. A plurality of water passing grooves 15 are arranged on the side surface of the lifting cylinder 11. Through the water passing grooves 15, water flows from below the fixed ring 10 to above the fixed ring 10. The cross-sectional area of the water passing grooves 15 gradually increases from top to bottom, and at least one side surface of the water passing grooves 15 is an inclined surface, and this inclined surface is arranged obliquely upward. The lifting cylinder 11 is connected to the lifting disc 17 through a connecting column 16. A plurality of cleaning needles 19 are installed on the bottom surface of the lifting disc 17. The cleaning needles 19 are used to clean the meshes on the filtering disc 20. The diameter of the cleaning needles 19 is smaller than the diameter of the meshes on the filtering disc 20. When the cleaning needles 19 are inserted into the meshes, water can still pass through the filtering disc 20. When the working power of the water pump 4 changes periodically, the flow rate of the well water passing through the water passing grooves 15 will change. The greater the flow rate, the greater the pressure on the water passing grooves 15, thereby causing the lifting cylinder 11 to move upward; the smaller the flow rate, the smaller the pressure on the water passing grooves 15, and the lifting cylinder 11 will move downward under the action of gravity. In this way, the lifting cylinder 11 performs a reciprocating lifting motion. The cleaning needles 19 will also perform a reciprocating lifting motion. When the cleaning needles 19 are at the lower end of the stroke, the cleaning needles 19 will be inserted into the meshes. When the cleaning needles 19 are at the upper end of the stroke, the cleaning needles 19 will be separated from the filtering disc 20. Further, a sand grain collection mechanism is also arranged at the bottom of the treatment cylinder body 1. The reciprocating lifting motion of the lifting cylinder 11 will cause the sand grain collection mechanism to work synchronously to collect the sand grains in the well and reduce the sedimentation amount of the sand grains at the bottom of the well.

[0026] In the embodiment of the present invention, the bottom of the treatment cylinder body 1 is sealed. The collected and intercepted sand grains will be deposited at the bottom of the treatment cylinder body 1. By pulling the treatment cylinder body 1 out of the well, the sand grains deposited at the bottom can be removed. A water inlet inclined pipe 5 is connected to the side surface of the treatment cylinder body 1. The water inlet inclined pipe 5 is inclined. The outer port of the water inlet inclined pipe 5 is higher than the inner port of the water inlet inclined pipe 5. A set distance is provided between the inner port of the water inlet inclined pipe 5 and the bottom of the treatment cylinder body 1. In this way, the sand grains entering the inside of the treatment cylinder body 1 can smoothly settle at the bottom.

[0027] Please refer to Figures 1 to 7, in the embodiment of the present invention, the sand collection mechanism includes a plurality of threaded shafts 7 and a rotating disk 22, and the threaded shafts 7 and the rotating disk 22 correspond one by one. The threaded shaft 7 is connected to the lifting disk 17, and the threaded shaft 7 is arranged outside the processing cylinder 1. A mounting frame 23 is fixedly connected to the outer side surface of the processing cylinder 1. The rotating disk 22 is rotatably mounted on the mounting frame 23. Threaded holes are provided on the rotating disk 22, and the threaded shaft 7 is in mating connection with the corresponding threaded holes. A stirring assembly 8 is connected to the rotating disk 22. When the lifting disk 17 makes a reciprocating lifting motion, the threaded shaft 7 will also make a reciprocating lifting motion, thereby causing the rotating disk 22 to rotate, and the stirring assembly 8 works to stir up the sand grains at the bottom of the water well, and a large amount of sand grains enter the processing cylinder 1 through the water inlet inclined pipe 5.

[0028] In the embodiment of the present invention, the processing cylinder 1 and the threaded shaft 7 are both vertically arranged, the fixed ring 10, the lifting disk 17 and the filter disk 20 are all horizontally arranged. The stirring assembly 8 includes a stirring shaft 81 and stirring blades 82. The stirring shaft 81 is fixedly connected to the bottom surface of the rotating disk 22. A plurality of the stirring blades 82 are connected to the stirring shaft 81. When in use, the processing cylinder 1 is vertically placed at the bottom of the water well.

[0029] In the embodiment of the present invention, the threaded shaft 7 is connected to the lifting disk 17 through a horizontal plate 6 and a vertical column 21. The vertical column 21 is fixedly connected to the lifting disk 17 and penetrates through the filter disk 20. One end of the horizontal plate 6 is connected to the vertical column 21, and the other end of the horizontal plate 6 is connected to the threaded shaft 7. A through groove one 9 is provided on the side surface of the processing cylinder 1. The horizontal plate 6 passes through the through groove one 9, and the horizontal plate 6 makes a lifting motion along the through groove one 9. Preferably, two threaded shafts 7 and rotating disks 22 are provided and are symmetrically distributed.

[0030] In the embodiment of the present invention, a guide plate 12 is connected to the surface of the lifting cylinder 11. Guide through holes are provided on the guide plate 12. A guide shaft 13 is connected to the top surface of the fixed ring 10. The guide shaft 13 penetrates through the guide through hole and is in sliding fit connection with the inner wall of the guide through hole. A limit block is connected to the top end of the guide shaft 13. A plurality of through grooves two 18 are provided on the surface of the lifting disk 17. Through the arrangement of the guide plate 12 and the guide shaft 13, the operation of the lifting cylinder 11 is more stable.

[0031] In the embodiment of the present invention, a connection head 2 is provided at the top end of the processing cylinder 1. The connection head 2 is connected to the water inlet of the water pump 4 through a water pipe 3. By pulling up the processing cylinder 1 from the water well through the water pipe 3, the sand grains deposited at the bottom of the processing cylinder 1 can be cleaned quickly and conveniently.

[0032] The working process of the embodiment of the present invention is as follows: When it is necessary to clean the mesh holes in the filter disc 20, the frequency converter is controlled so that the working power of the water pump 4 changes periodically, and the flow rate of the well water passing through the water passing groove 15 also changes periodically. The upward pressure received by the water passing groove 15 will change, and the lifting cylinder 11 realizes reciprocating lifting motion. Furthermore, the cleaning needle 19 will also perform reciprocating lifting motion to clean the mesh holes in the filter disc 20. At the same time, the threaded shaft 7 will also perform reciprocating lifting motion, which will cause the rotating disc 22 to rotate, and the stirring assembly 8 will work, causing the sand grains at the bottom of the water well to be stirred up. A large number of sand grains enter the treatment cylinder 1 through the water inlet inclined pipe 5, realizing the collection work of the sand grains at the bottom of the well.
