Description

Technical Field

[0001] This utility model relates to the field of brine treatment technology, and in particular to a brine filtration device. Background Technology

[0002] The brine return process is mainly used in the salt chemical industry, especially in the field of well salt mining. This process involves injecting fresh water or brine into the rock salt layer through injection wells, allowing the water to circulate and dissolve the rock salt within the rock salt layer to form brine. The brine is then returned to the surface through return wells, and after further treatment and transportation, qualified brine that meets production requirements is finally obtained.

[0003] Currently, the qualified brine extracted from salt wells mainly consists of sodium chloride, water, and various trace elements and impurities. Among these, the impurities mainly include mud and sand, algae, and other particulate matter. During brine processing, these impurities will adhere to the surface of the brine processing equipment, which usually requires filtration. Otherwise, the processing equipment may be damaged, leading to production quality problems. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-7 As shown, a brine filtration device includes a filter cylinder 1 with an open top and a drain pipe 3 connected to the bottom. A support ring 9 is fixed to the inner wall of the filter cylinder 1. A filter screen 8 is provided in the middle of the filter cylinder 1. The filter screen 8 has a hollow cylindrical structure and an open top. A limit ring 10 is fixed to the top edge of the filter screen 8 and can be placed above the support ring 9. An inlet pipe 6 is provided on one side of the top of the filter cylinder 1, and a support assembly for supporting the inlet pipe 6 is provided on the side wall of the filter cylinder 1. Brine is discharged after passing through the inlet pipe 6 and flows directly into the filter screen 8. The brine flows into the internal space of the filter cylinder 1 through the filter holes of the filter screen 8 and is finally discharged outward through the drain pipe 3. An external pipe is connected to the end of the drain pipe 3 to continue transporting brine to meet the brine transport requirements.

[0025] like Figure 1 and Figure 4 As shown, the support assembly includes a support base 4 fixed to the side wall of the filter cylinder 1. The top of the support base 4 is provided with a sliding groove 41, and a positioning sleeve 5 is provided above the sliding groove 41. The side wall of the positioning sleeve 5 is provided with a through hole, into which the end of the liquid inlet pipe 6 is inserted and fixed with bolts. The positioning sleeve 5 supports and stabilizes the liquid inlet pipe 6. After the brine is discharged from the end of the liquid inlet pipe 6, it can flow directly into the filter cylinder 1. The positioning sleeve 5 can slide on the sliding groove 41, which is beneficial to adjust the position of the end of the liquid inlet pipe 6 and facilitates the removal of the filter screen 8 later.

[0026] like Figure 5As shown, a washer 91 is provided between the support ring 9 and the limiting ring 10. The washer 91 is made of rubber, which has corrosion resistance and cushioning properties. A pin 92 is fixed to the bottom of the washer 91, and a pin hole 93 is opened on the top of the support ring 9 to cooperate with the pin 92. By inserting the pin 92 into the pin hole 93, the bottom of the washer 91 is tightly fitted with the top of the support ring 9. The washer 91 reduces the friction between the limiting ring 10 and the support ring 9, thereby protecting the support ring 9 from wear and ensuring that the support ring 9 can be used continuously.

[0027] like Figure 5 and Figure 6 As shown, several lifting rings 12 are fixed to the top of the limiting ring 10. By lifting the lifting rings 12 upwards with an external crane, the limiting ring 10, the filter screen 8, and all the internal structures of the filter screen 8 can be moved upwards, thereby removing the filter screen 8 out of the filter cylinder 1. This facilitates the rinsing and cleaning of the filter cylinder 1 and its internal structures, which is beneficial for the sustainable use of the filter cylinder 1.

[0028] like Figures 1-7 As shown, a central rod 11 is threadedly connected to the center of the filter screen 8. Multiple support plates 14 are fixed to the outer wall of the central rod 11. A filter plate 13 is placed on the top of each support plate 14. Since the structure of the filter plate 13 is already existing technology, the filter holes of the filter plate 13 are not shown in the figure. The filter mesh number of the multiple filter plates 13 decreases from top to bottom, so that impurities of different particle sizes can be filtered. When the filter screen 8 is lifted to the outside of the filter cylinder 1, the central rod 11 can be rotated to make the central rod 11 detach from the filter screen 8. Then the multiple filter plates 13 can be taken out, and each filter plate 13 can be rinsed to clean the impurities on its surface.

[0029] like Figures 1-4As shown, the outer wall of the filter cylinder 1 is also provided with a guide seat 74, and the top of the guide seat 74 is provided with a liftable guide column 73. The top of the guide column 73 is fixed with a bracket 72, and the extended end of the bracket 72 is fixed with a nozzle 7. The outer wall of the nozzle 7 is provided with several drainage holes. When the water pressure inside the nozzle 7 is too high, clean water is sprayed out from the drainage holes. The nozzle 7 can be hoisted above the filter cylinder 1 by an external hoisting structure. In actual use, it is moved up and down by an external crane. The top of the nozzle 7 is connected to a connecting pipe 71, and the end of the connecting pipe 71 is connected to an external water pipe through a flange. Clean water is drawn out by an external water pump. Water enters the connecting pipe 71 and then pressurizes the nozzle 7. A support frame 2 is installed on the outer wall of the filter cylinder 1 to ensure the overall stability of the filter cylinder 1. During the cleaning of the inner wall of the filter cylinder 1, the filter screen 8 is first lifted upwards by a crane and removed from the filter cylinder 1. Then, the nozzle 7 is moved downwards by the crane. The nozzle 7 moves vertically with the guidance of the guide column 73 without shaking. The nozzle 7 sprays clean water onto the inner wall of the filter cylinder 1 to achieve the purpose of rinsing, thereby avoiding the problem of corrosive impurities in the brine corroding the inner wall of the filter cylinder 1 and improving the service life of the filter cylinder 1.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
