[0002] In the process of mining underground brine resources, due to the changes in the composition of underground mineral deposits, changes in the ground environment, and static electricity, some insoluble components in the brine, such as sulfates, carbonates, phosphates, etc., will crystallize and precipitate. These substances, together with the mud and fine stones contained in the brine, are easily attached to the inner wall of the pipeline or deposited on the water meter, elbows, valves and other accessories, forming a scale layer, resulting in a reduction in the pipeline diameter and clogging of pipeline accessories, which will not only increase energy consumption and reduce production efficiency, but also corrode the pipeline and cause perforation and leakage accidents. Therefore, a brine well pipeline anti-blocking device is urgently needed to solve the above problems. Utility Model Content

[0020] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0021] like Figures 1 to 3As shown, a brine well pipeline anti-blocking device described in the utility model comprises a shell 1, a supporting leg is arranged at the bottom of the shell 1, and a liquid inlet pipe 2 and a liquid discharge pipe 3 are respectively arranged on the side walls of the shell 1 for the input and output of brine; a filter screen cylinder 4 is arranged inside the shell 1, the filter screen cylinder 4 is open at the bottom, and the other sides are of a mesh structure, wherein the outer diameter of the filter screen cylinder 4 is smaller than the inner diameter of the shell 1, so as to form a cavity for the filtered brine to flow between the shell 1 and the filter screen cylinder 4; the liquid inlet pipe 2 is connected with the filter screen cylinder 4 to realize the filtering of the brine; a rotating shaft 7 is rotatably arranged in the filter screen cylinder 4, an impeller 5 is arranged on the rotating shaft 7 at a position opposite to the liquid inlet pipe 2, a cleaning brush 6 is arranged on the rotating shaft 7 below the impeller 5, and the cleaning brush 6 is in contact with the inner wall of the filter screen cylinder 4. During operation, the liquid enters the filter screen cylinder 4 from the drain pipe 3. With the continuous delivery of the liquid, the impeller 5 is driven to rotate, thereby driving the rotating shaft 7 and the cleaning brush 6 to rotate, so as to clean the inner wall of the filter screen cylinder 4, reduce the probability of dirt adhering to the inner wall of the filter screen cylinder 4, and improve the filtering efficiency. The filtered brine liquid flows out of the filter screen cylinder 4 and fills the cavity between the filter screen cylinder 4 and the housing 1, and is finally discharged through the drain pipe 3. By filtering the brine, the content of dirt inside the brine is greatly reduced, and the probability of the brine delivery pipeline being blocked and corroded is reduced, ensuring the smooth progress of the work.

[0022] Furthermore, in this embodiment, two cleaning brushes 6 are provided, symmetrically arranged on both sides of the rotating shaft 7, so as to improve the cleaning effect of the multi-filter screen cartridge 4 and ensure the balance of the rotating shaft 7 when rotating. In addition, the height of the liquid inlet pipe 2 is preferably higher than that of the liquid discharge pipe 3, so as to achieve high inlet to low place, increase the filtering area, and avoid the problem that the dirt accumulated at the bottom of the shell 1 is not cleaned in time due to the low setting position of the liquid inlet pipe 2, and the mesh of the filter screen cartridge 4 is blocked to cause low filtering efficiency; wherein the liquid inlet pipe 2 and the liquid discharge pipe 3 are arranged on the symmetrical two sides of the shell 1, so as to achieve smooth input and output of brine.

[0023] Furthermore, a slag discharge port 8 is provided on the bottom wall of the shell body 1 located in the filter screen cylinder 4, and a sealing plate 12 is rotatably provided at the bottom of the shell body 1. A through hole 9 matching the slag discharge port 8 is opened on the sealing plate 12. In the initial state, the slag discharge port 8 and the through hole 9 are misaligned to achieve sealing of the inside of the shell body 1. When it is necessary to discharge dirt, the sealing plate 12 is rotated to make the through hole 9 provided thereon coincide with the slag discharge hole. Preferably, a funnel-shaped air deflector 10 is provided at the bottom of the shell 1. The air deflector 10 is a structure with a hollow interior and through-holes at both ends, so as to provide diversion for dirt and realize smooth discharge of dirt; a rotating rod 11 is provided on the sealing plate 12, and the bottom end of the rotating rod 11 extends downward from the air deflector 10, and the sealing plate 12 can be driven to rotate by controlling the rotation of the rotating rod 11, thereby realizing the overlap or misalignment of the through hole 9 and the slag discharge port 8; wherein the rotating rod 11 can be selected according to the setting position of the device to select manual regular slag discharge or automatic control to open. When automatic control to open the slag discharge is required, gears, pulleys, sprockets, etc. can be set at the bottom of the rotating rod 11. The rotation of the rotating rod 11 can be realized through gear transmission, pulley transmission or sprocket chain transmission. The timed automatic slag discharge operation can be completed by timing the control system to control the motor to start.

[0024] In addition, a conical guide portion 13 is provided on the inner bottom wall of the shell 1, and the slag discharge port 8 is provided on the inner bottom wall of the shell 1 around the guide portion 13. The guide portion 13 helps to provide guidance for the settled dirt, so that it accumulates at the position of the slag discharge port 8, so that the dirt can be subsequently discharged in a concentrated manner.

[0025] Furthermore, an inspection port 14 is provided at the top of the shell 1, and a sealing top plate 15 connected to the shell 1 is provided at the top of the inspection port 14. The inspection port 14 and the sealing top plate 15 are detachably connected by bolts, which facilitates the inspection and maintenance of the internal structure of the shell 1. In addition, a flushing pipe 16 communicating with the inside of the shell 1 is provided on the sealing top plate 15, and a sealing cover 17 is provided at the top of the flushing pipe 16. The flushing pipe 16 can be used to pass clean water to clean the inner wall of the shell 1 and the outer wall of the filter screen cylinder 4, thereby enhancing the practicality of the utility model; in addition, one side of the flushing pipe 16 is communicated with the drain pipe 3 through a connecting pipe 19, and a valve 18 is provided on the connecting pipe 19. Through the setting of the connecting pipe 19, the valve 18 can also be opened regularly to temporarily flush the inside of the shell 1 and the filter screen cylinder 4 with the filtered liquid to ensure the cleanliness of the inside of the shell 1.

[0026] When the utility model is in use, liquid first enters the filter screen cylinder 4 through the liquid inlet pipe 2. As the liquid is continuously transported, the liquid provides power for the impeller 5, driving the impeller 5 to rotate, and then driving the cleaning brush 6 to rotate, so as to clean the inner wall of the filter screen cylinder 4 and reduce the probability of the filter screen cylinder 4 being blocked; the filtered liquid is filled between the shell 1, the inner wall and the filter screen cylinder 4, and finally transported to the brine transport pipeline through the discharge pipe 3 for transportation; when slag discharge is required, the sealing plate 12 at the bottom of the shell 1 is rotated to discharge the slag. The whole device has a simple structure and is easy to operate. It greatly reduces the probability of scaling and blockage on the inner wall of the pipeline, ensures production efficiency, and reduces the adverse effects on the pipeline.
