[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art in the field of circulating water filtration based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0029] As Figure 1 and 2 shown, the present utility model provides a circulating water filter, including a housing 1:

[0030] One side of the housing 1 is movably connected with a cover plate 6 through a hinge. One end inner wall of the housing 1 is fixedly provided with a water inlet 8. A fiber filter cartridge 9 is movably arranged on the outer surface of the water inlet 8. The lower end of the housing 1 is fixedly provided with a water outlet pipe 7. A plurality of heat dissipation grooves 5 are arranged on the outer surface of the housing 1.

[0031] In order to be able to guide the insertion of the fiber filter cartridge 9, a filter cartridge guiding device 2 for guiding and docking the fiber filter cartridge 9 is arranged on the inner wall of the housing 1, which is used to guide the fiber filter cartridge 9 to be inserted into the outer end of the water inlet 8, so that the fiber filter cartridge 9 can be more conveniently docked with the water inlet 8;

[0032] As Figure 3 shown, the filter cartridge guiding device 2 includes an inclined ring 21. The inclined ring 21 is fixedly arranged on one end inner wall of the housing 1. The inclined ring 21 is located on the outer surface of the water inlet 8. One end of the fiber filter cartridge 9 is fixedly provided with an adapter ring 22. The inner wall of the adapter ring 22 is movably connected with the outer surface of the water inlet 8. One end of the adapter ring 22 is provided with an inclined cut end 23. The inclined cut angle of the inclined cut end 23 is the same as the inclined angle of the inclined ring 21. By movably inserting the fiber filter cartridge 9 into the housing 1 and inwardly squeezing the fiber filter cartridge 9, the inclined cut end 23 slides on the inclined ring 21, thereby guiding the adapter ring 22 at one end of the fiber filter cartridge 9 to be docked with the water inlet 8. Therefore, the problem of troublesome manual installation is avoided, and when different fiber filter cartridges 9 are required for filtering the circulating water, it can be conveniently replaced.

[0033] Furthermore, in order to be able to connect and fix the fiber filter cartridge 9, an extrusion sealing device 3 for extruding and fixing the fiber filter cartridge 9 is arranged at one end of the housing 1, which is used to realize the extrusion of the fiber filter cartridge 9 through the combination of the cover plate 6 and the housing 1, so that the position of the fiber filter cartridge 9 is fixed;

[0034] As Figure 4As shown in the figure, the extrusion sealing device 3 includes a rubber push block 31, which is fixedly arranged on one side of the cover plate 6. A rubber ring 32 is fixedly arranged on the outer ring of one side of the cover plate 6. One end of the outer shell 1 is fixedly provided with a fixing plate 33. The cover plate 6 and the fixing plate 33 are fixedly penetrated by a threaded bolt 34. By using the hinge connection method of the cover plate 6, when the cover plate 6 is closed, the rubber push block 31 can be driven into one end of the outer shell 1, thereby extruding the fiber filter cartridge 9. Through the rubber ring 32 on the outer ring of one side of the cover plate 6, the effect of extrusion sealing can be achieved. After the cover plate 6 is combined, it is locked by the threaded bolt 34, so as to achieve the effect of fixing the extruded fiber filter cartridge 9. When replacement is needed, loosen the threaded bolt 34, and the fiber filter cartridge 9 can be taken out more conveniently.

[0035] Furthermore, in order to be able to alarm and remind the staff to replace or clean the fiber filter cartridge 9, a pressure detection device 4 for alarming according to excessive water inlet pressure is arranged at the other end of the outer shell 1, which is used to alarm and remind the staff when the fiber filter cartridge 9 is blocked and the water inlet pressure is too high;

[0036] As Figure 5 shown in the figure, the pressure detection device 4 includes a water inlet pipe 41. A slot 42 is opened on the inner wall of one end of the water inlet pipe 41. Flanges 43 are respectively fixedly arranged at both ends of the water inlet pipe 41. The water inlet pipe 41 is movably connected to one end of the outer shell 1 through the flange 43. A pressure controller 44 is fixedly arranged at the upper end of the water inlet pipe 41. A wire 45 is fixedly arranged at the output end of the pressure controller 44. One end of the wire 45 is fixedly provided with an alarm 46. The lower end of the alarm 46 is fixedly connected to the upper end of the water inlet pipe 41. Through the circulating water input from the water inlet pipe 41, it flows into the water inlet 8 and the fiber filter cartridge 9. When the fiber filter cartridge 9 is blocked, the water flow pressure in the water inlet pipe 41 will increase. When the water flow pressure is greater than the set pressure of the pressure controller 44, an electric current signal is transmitted through the wire 45 to make the alarm 46 give an alarm. Therefore, the staff can be reminded in time to replace or clean the fiber filter cartridge 9.

[0037] The working principle is as follows: When the present invention is in use, the circulating water outlet is connected through the flange 43, so that the circulating water flows into the water inlet pipe 41, and then into the water inlet 8 and the fiber filter cartridge 9. The fiber filter cartridge 9 is used for filtration. When the fiber filter cartridge 9 is blocked, the pressure detection device 4 will give an alarm, thereby closing the input of the circulating water. The fiber filter cartridge 9 is drawn out by opening the extrusion sealing device 3, and then a new fiber filter cartridge 9 is inserted. The fiber filter cartridge 9 is guided and inserted according to the filter cartridge guiding device 2, so as to close the extrusion sealing device 3 to fix the fiber filter cartridge 9, thereby achieving the effect of convenient replacement.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
