[0002] The bag filter tank is a multi-purpose filtering equipment with small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability. The filter bag is supported by a metal mesh basket inside the bag filter tank. The liquid is discharged after being filtered by the filter bag, and impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used. The filter bag is easy to replace and the filter bag is easy to clean and reuse. The cost of use is low. It is often used in the field of industrial water or drinking water filtration. However, in order to improve the filtering effect, the existing bag filter tank usually uses high-precision filter bags. The filter aperture of high-precision filter bags is small. The bag body is easy to clog after a period of use. After water passes through, it will cause a certain proportion of pressure drop, and the filter bag needs to be cleaned and replaced frequently.

[0024] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 As shown, a water treatment filter tank includes a tank body 1, a cover body 2, a partition plate 11, a first filter assembly 3, and a second filter assembly 4. The tank body 1 is a cylindrical tank made of stainless steel and supported by multiple support legs. The outer ring of the top of the tank body 1 is provided with multiple quick-opening bolts 19. The outer circumference of the cover body 2 is provided with an outer ring plate, which is provided with through grooves corresponding to the quick-opening bolts 19. The cover body 2 is covered on the tank body 1 through the multiple quick-opening bolts 19, and the cover body 2 is quickly opened and closed. Two lifting rings are connected to the outer top wall of the cover body 2 for easy lifting. The top wall of the cover body 2 is provided with a first inlet pipe 21, through which water from outside the first inlet pipe 21 enters the internal space of the tank body 1.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the partition plate 11 is arranged near the upper end of the tank body 1. The partition plate 11 divides the tank body 1 into two spaces, one above and one below. The partition plate 11 is provided with four first through holes, which are distributed in a circular array. Four first filter components 3 are also provided. The first filter component 3 includes a filter cartridge 31 and a filter bag 32. The filter cartridge 31 is a straight stainless steel cylinder with mesh holes on the cylinder wall. When in use, the filter cartridge 31 passes through the first through hole of the partition plate 11. The cylinder body of the filter cartridge 31 is located below the partition plate 11, and the top of the filter cartridge 31 is located on the partition plate 11. The filter bag 32 is arranged in the filter cartridge 31. The filter cartridge 31 supports the filter bag 32. The filter bag 32 adopts a low filtration precision filter bag, for example, a filtration precision of 400μm. The filter bag 32 is also straight, with an open top and a closed bottom. A pressing assembly 5 is provided on the partition plate 11, and the pressing assembly 5 includes a first pressing circular plate 51, a spring 52, a second pressing plate 53 and a fixed buckle plate 54. The first pressing circular plate 51 is a circular plate with side edges. The first pressing circular plate 51 is used to press the upper end of the filter bag 32 onto the inner wall of the top end of the filter cylinder 31. The spring 52 is connected to the center position of the upper end surface of the first pressing circular plate 51. The second pressing plate 53 is a strip plate used to press on the spring 52. Each pressing assembly 5 includes two fixed buckle plates 54, which are symmetrically arranged on the top wall of the partition plate 11 and on both sides of the first through hole. The fixed buckle plate 54 is an inverted L-shaped plate. When the second lower pressure plate 53 is pressed on the spring 52, the second lower pressure plate 53 is rotated so that the two ends of the second lower pressure plate 53 are located below the corresponding fixed buckle plate 54, thereby limiting the second lower pressure plate 53. The second lower pressure plate 53 maintains pressure on the first lower pressure circular plate 51 through the spring 52, thereby limiting the filter bag 32 in the filter cylinder 31. Four third through holes 511 are provided on the first lower pressure circular plate 51. The water above the partition plate 11 enters the filter bag 32 through the third through holes 511, and reaches the space below the partition plate 11 after being filtered by the filter bag 32.

[0027] like Figure 1 and Figure 4 As shown, the second filter assembly 4 is arranged below the partition plate 11. The second filter assembly 4 includes an activated carbon filter layer 41 and a support plate frame 42. A barrier ring is provided on the inner wall of the tank body 1. The support plate frame 42 is placed on the barrier ring. The activated carbon filter layer 41 is located above the support plate frame 42. The activated carbon filter layer 41 uses coconut shell activated carbon, which has an amorphous particle shape and has high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, and good adsorption capacity for various solutes and free gases. The support plate frame 42 is a circular plate and includes a first splicing plate 421 and a second splicing plate 422. The first splicing plate 421 and the second splicing plate 422 are spliced ​​together to form a semicircle. The two semicircles are spliced ​​together to form a full circle, thus forming a circular support plate frame 42. The upper and lower panels of the two splicing plates of the support plate frame 42 are mesh panels with a hollow center. Both splicing plates contain filter cotton 43, forming a filter cotton layer. The filter cotton 43 is made of polyester fiber and is used to filter suspended matter and impurities. A working hole 18 is opened in the side wall of the tank body 1, and a blind plate is connected to the working hole 18. The provision of the working hole 18 facilitates the replacement of the carbon filter layer 41 and the filter cotton 43.

[0028] like Figure 1 As shown, a second inlet pipe 13 is provided on the side wall of the tank body 1. The second inlet pipe 13 is located above the partition plate 11. A water distribution plate 14 is provided in the tank body 1. The water distribution plate 14 is also located above the partition plate 11. A corresponding support ring is provided on the top side wall of the tank body 1. The water distribution plate 14 is placed on the support ring. The water distribution plate 14 is inverted conical shape and is made of food-grade polypropylene. The water distribution plate 14 is provided with a second through hole 142 corresponding to the second inlet pipe 13. Water entering the second inlet pipe 13 or the water entering the first inlet pipe 21 reaches above the water distribution plate 14. The water distribution plate 14 is provided with multiple water distribution through holes. Water above the water distribution plate 14 flows downward through the water distribution through holes, thereby ensuring that the water entering the filter bag 32 is evenly distributed. The first inlet pipe 21 and the second inlet pipe 13 can be set by selecting appropriate water inlet pipes according to the installation environment. The bottom of the tank body 1 is provided with an outlet pipe 12. Water filtered by the first filter assembly 3 and the second filter assembly 4 is discharged from the outlet pipe 12. An insulation layer 6 is provided outside the tank body 1. The insulation layer 6 is made of insulation cotton or polyurethane foam board and is used to keep the outside of the tank body 1 warm, reduce heat exchange with the outside in a low temperature environment, and ensure the activated carbon filtering effect.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
