A partition plate 7 is installed on the inner wall of the box body 2. The right side of the partition plate 7 is the first filtration chamber 8, and the left side of the partition plate 7 is the second filtration chamber 9. A driving rod 10 is rotatably installed on the inner wall of the box body 2. A moving plate 11 is welded on the driving rod 10. A glass window 12 is installed on the rear plate of the box body 2. One side of the driving rod 10 penetrates through the glass window 12 and is fixedly sleeved with a worm gear 13. Two groups of fixing blocks 14 are installed on the rear plate of the box body 2. A worm 15 is rotatably installed on the fixing blocks 14. A first knob 16 is welded on one side of the worm 15. The worm 15 meshes with the worm gear 13. The first filtration chamber 8 and the second filtration chamber 9 are symmetrically arranged. Four groups of placement grooves 17 are opened on the side wall of the first filtration chamber 8 and the side wall of the partition plate 7. Four groups of rod grooves 18 are opened on the outer wall of the first filtration chamber 8. A first filter box 19, a second filter box 20, a third filter box 21 and a fourth filter box 22 are respectively placed in the four groups of placement grooves 17. The first filter box 19 includes a box body 23. The box body 23 is made of a heat-conducting material. A filter screen 24 is installed on the bottom side of the box body 23. A heat-insulating plate 25 is installed on the side wall of the box body 23. A screw rod 26 penetrates through the heat-insulating plate 25. The screw rod 26 is slidably matched with the heat-insulating plate 25 through threads. The screw rod 26 is assembled in the rod groove 18. A second knob 27 is installed on the screw rod 26. The second filter box 20, the third filter box 21 and the fourth filter box 22 have the same structure as the first filter box 19 but different specifications. The densities of the first filter box 19, the second filter box 20, the third filter box 21 and the fourth filter box 22 increase in turn. During operation, in the process of filtering brine by the existing filtering device, due to the accumulation of impurities on the filter screen 24 after long-term use and inconvenient cleaning, the filtering effect decreases. Pour the brine into the box body 2 from the feed pipe 4. At this time, since the moving plate 11 is in contact with the first baffle plate 5, the feed port of the second filtration chamber 9 is closed, and the feed port of the first filtration chamber 8 is opened. The brine is poured into the first filtration chamber 8, and then passes through the first filter box 19, the second filter box 20, the third filter box 21 and the fourth filter box 22 in the first filtration chamber 8 in turn, filtering a large amount of impurities such as sediment, suspended matter, colloid and organic matter in the brine in turn. After that, the brine with qualified turbidity after filtration is discharged from the discharge pipe 29. After using for a period of time, excessive impurities accumulate inside the first filter box 19, the second filter box 20, the third filter box 21 and the fourth filter box 22 in the first filtration chamber 8, and they need to be cleaned;

[0020] By rotating the first knob 16, the worm 15 is driven to rotate. The worm 15 pushes the worm wheel 13 to rotate. The combination of the worm 15 and the worm wheel 13 has self-locking property. The worm wheel 13 drives the drive rod 10 to rotate, and the drive rod 10 drives the moving plate 11 to rotate. The moving plate 11 rotates and abuts against the second baffle plate 6. At this time, the moving plate 11 abuts against the second baffle plate 6, the feed inlet of the first filtration chamber 8 is closed, and the feed inlet of the second filtration chamber 9 is opened. The brine is poured into the second filtration chamber 9. The first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the second filtration chamber 9 continue to filter the brine, realizing continuous filtration of the brine. During the process of cleaning the impurities inside the first filtration chamber 8, the filtration of the brine will not be affected;

[0021] After the feed inlet of the first filtration chamber 8 is closed, by rotating the four groups of second knobs 27, the second knobs 27 drive the screw rods 26 to rotate. The screw rods 26 are separated from the rod grooves 18 of the box body 2, unlocking the fixed connection between the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 and the box body 2. At this time, by pulling out the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 outward, the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 can be directly disassembled from the box body 2. Then, the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 are cleaned, realizing the cleaning of the four filter boxes inside the first filtration chamber 8. This structure avoids the accumulation of impurities on the filter mesh 24 and realizes the convenient cleaning of the filter mesh 24, which is beneficial to improving the filtration effect.

[0022] Please refer to Figure 3 As shown, a heating plate 28 is installed inside the partition plate 7. The heating plate 28 is connected to the control panel 3 through an internal circuit; during operation, in the existing filtration device during the filtration of brine, due to seasonal temperature changes, when it is winter and autumn and the temperature drops, the saturated magnesium chloride brine is prone to crystallization at low temperatures, and the crystals are easy to condense on the surface of the filter mesh 24, resulting in low filtration efficiency. The brine passes through the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the first filtration chamber 8, and a large amount of impurities such as sediment, suspended matter, colloid, and organic matter in the brine are filtered in turn. During this process, the control panel 3 controls the operation of the heating plate 28, and the heating plate 28 heats the partition plate 7. The partition plate 7 heats the box bodies 23 of the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 and the filter mesh 24. The box bodies 23 and the filter mesh 24 heat the brine, avoiding the brine from getting too cold and forming crystals, and avoiding the formation and condensation of crystals on the surface of the filter mesh 24, which is beneficial to improving the filtration efficiency.

[0023] Working principle: During the filtration of brine by the existing filtration device, due to the accumulation of impurities on the filter screen 24 after long-term use and the inconvenience of cleaning, the filtration effect decreases. The brine is poured into the box body 2 from the feed pipe 4. At this time, since the moving plate 11 is in contact with the first baffle plate 5, the feed port of the second filtration chamber 9 is closed, and the feed port of the first filtration chamber 8 is opened. The brine is poured into the first filtration chamber 8 and then successively passes through the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the first filtration chamber 8 to filter a large amount of impurities such as sediment, suspended matter, colloid, and organic matter in the brine in sequence. Then, the brine with qualified turbidity after filtration is discharged from the discharge pipe 29. After using for a period of time, excessive impurities accumulate inside the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the first filtration chamber 8, and they need to be cleaned. By rotating the first knob 16, the worm 15 is driven to rotate. The worm 15 pushes the worm gear 13 to rotate. The worm gear 13 drives the drive rod 10 to rotate. The drive rod 10 drives the moving plate 11 to rotate. The moving plate 11 rotates and comes into contact with the second baffle plate 6. At this time, the moving plate 11 is in contact with the second baffle plate 6, the feed port of the first filtration chamber 8 is closed, and the feed port of the second filtration chamber 9 is opened. The brine is poured into the second filtration chamber 9, and the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the second filtration chamber 9 continue to filter the brine, realizing continuous filtration of the brine. During the cleaning process of the impurities inside the first filtration chamber 8, the filtration of the brine will not be affected. After the feed port of the first filtration chamber 8 is closed, by rotating the four groups of second knobs 27, the second knobs 27 drive the screw rods 26 to rotate. The screw rods 26 are separated from the rod grooves 18 of the box body 2, unlocking the fixed connection between the first filter box 19, the second filter box 20, the third filter box 21, the fourth filter box 22 and the box body 2. At this time, by pulling out the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 outward, the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 can be directly disassembled from the box body 2, and then the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 are cleaned, realizing the cleaning of the four filter boxes in the first filtration chamber 8. This structure avoids the accumulation of impurities on the filter screen 24, realizes the convenient cleaning of the filter screen 24, and is beneficial to improving the filtration effect;During the process of filtering brine by the existing filtering device, due to seasonal temperature changes, when it is winter and autumn and the temperature drops, the saturated magnesium chloride brine is prone to crystallization at low temperatures, and the crystals are likely to condense on the surface of the filter screen 24, resulting in low filtering efficiency. The brine passes through the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22 in the first filtering chamber 8 to sequentially filter a large amount of impurities such as sediment, suspended matter, colloid, and organic matter in the brine. During this process, the control panel 3 controls the operation of the heating plate 28, the heating plate 28 heats the partition plate 7, the partition plate 7 heats the box bodies 23 and the filter screens 24 of the first filter box 19, the second filter box 20, the third filter box 21, and the fourth filter box 22, and the box bodies 23 and the filter screens 24 heat the brine, avoiding the formation of crystals due to too low brine temperature, preventing the appearance and condensation of crystals on the surface of the filter screen 24, which is beneficial to improving the filtering efficiency.
