DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.

[0031] Refer to Figures 1 to 3 ​The utility model provides a kind of stainless steel filter of filter core is replaced conveniently in an embodiment: a barrel 1, the top of barrel 1 is detachably connected with barrel cover 2, the barrel cover 2 here is used to prevent the liquid leakage in the inside of barrel 1, the left top of barrel 1 is fixedly connected with inlet pipe 3, the inlet pipe 3 here is used to receive the liquid needing filtering, the bottom right of barrel 1 is fixedly connected with outlet pipe 4, the outlet pipe 4 here is used to pass out clean filtered liquid, the top of barrel cover 2 is fixedly connected with detection table 5, the detection table 5 here can real-time monitoring the pressure or flow change in the inside of filter.The outside of barrel cover 2 is fixedly connected with two clamping columns 6, the barrel cover 2 here provides stable support for clamping column 6, the outside top of barrel 1 is rotatably connected with swivel ring 7;

[0032] The outside of swivel ring 7 is fixedly connected with clamping ring 8, the inner wall of clamping ring 8 is rotatably connected at the outside top of barrel 1, the clamping ring 8 here can drive swivel ring 7 to rotate at the outside of barrel 1, the inner wall of clamping ring 8 is rotatably connected at the outside of barrel cover 2, the inside of clamping ring 8 is provided with sliding slot 9, the inner wall of sliding slot 9 here is rounded, the outside of clamping column 6 is slidably connected at the inner wall of sliding slot 9.When needing to disassemble barrel cover 2, first can rotate clamping ring 8, because the inner wall of sliding slot 9 is rounded, so slightly force can make clamping column 6 separate from the clamping of sliding slot 9, then barrel cover 2 can be removed, so that the filter core in the inside of barrel 1 is taken out to clean.

[0033] The inner wall top of barrel cover 2 is detachably connected with rotating shaft 10, the bottom of rotating shaft 10 is detachably connected at the inner wall bottom of barrel 1, the rotating shaft 10 here can rotate at the inner wall bottom of barrel 1, the outside of rotating shaft 10 is fixedly connected with filter cylinder 11, the filter cylinder 11 here is used to filter the impurities in liquid, and the filter cylinder 11 here adopts spiral design, when water flow flows into the inside of barrel 1 from inlet pipe 3, the spiral groove on the surface of filter cylinder 11 is impacted, so as to drive filter cylinder 11 to rotate, so that filter cylinder 11 more comprehensively filters liquid, to prevent the situation that one side of filter cylinder 11 is clean, and the hole on the other side is blocked.The bottom of filter cylinder 11 is rotatably connected at the inner wall bottom of barrel 1, the top of filter cylinder 11 is detachably connected with cylinder plate 12, the cylinder plate 12 here is used to close the top of filter cylinder 11, the top of cylinder plate 12 is rotatably connected at the bottom of barrel cover 2, the inner wall top of barrel 1 is fixedly connected with fixed box 13, the inside of fixed box 13 is provided with recess 14, the inner wall of recess 14 is slidably connected with rubber ring 15, the recess 14 here provides stable sliding space for rubber ring 15, the top of rubber ring 15 is in contact with the bottom of barrel cover 2, the bottom of rubber ring 15 is fixedly connected with limiting ring 16;

[0034] Refer to Figures 2 to 4The outer part of the limiting ring 16 is slidably connected to the inner wall of the groove 14, and the limiting ring 16 can prevent the rubber ring 15 from being accidentally separated from the sliding inner wall of the groove 14. The bottom end of the limiting ring 16 is fixedly connected to the spring 17, and the other end of the spring 17 is fixedly connected to the inner wall of the groove 14. The spring 17 makes the rubber ring 15 more tightly pressed against the bottom end of the bucket cover 2, thereby ensuring the sealing performance of the device and preventing liquid leakage. The bottom end of the bucket body 1 is fixedly connected to the fixed assembly for supporting, and the fixed assembly includes the supporting leg 18. The top end of the supporting leg 18 is fixedly connected to the bottom end of the bucket body 1, and the bottom end of the supporting leg 18 is fixedly connected to the rubber pad 19. The supporting leg 18 provides stable support for the entire device, and the rubber pad 19 provides strong grip for the device, thereby further improving the stability of the device.

[0035] Working principle: First, the liquid to be filtered enters the bucket body 1 through the water inlet pipe 3, and at this time the filter cartridge 11 starts to work to filter the liquid. Since the filter cartridge 11 adopts a spiral design, the impact of the water flow will drive the filter cartridge 11 to rotate, so that the filter cartridge 11 can more comprehensively filter the liquid and prevent the situation of one side being clean and the other side being blocked. The filtered liquid flows out through the water outlet pipe 4, and the entire filtering process is completed.

[0036] When the filter element needs to be replaced, the clamping ring 8 can be rotated first. Since the inner wall of the sliding groove 9 is rounded, a little force can make the clamping column 6 disengage from the sliding groove 9, and then the bucket cover 2 can be removed, thereby facilitating the removal of the filter cartridge 11 inside the bucket body 1 for cleaning. Compared with the existing integral filter, the detachable design of the filter cartridge 11 makes it more convenient for the worker to clean the filter cartridge 11, thereby saving time and improving the filtering efficiency.

[0037] After completion, reverse operation can be performed to reinstall the bucket cover 2. At this time, the rubber ring 15 in the fixed box 13 will slide to the inside of the groove 14 after being pressed by the bucket cover 2, so that the spring 17 generates a counterforce, thereby making the rubber ring 15 more tightly pressed against the bottom end of the bucket cover 2, thereby ensuring the sealing performance of the device and preventing liquid leakage. At the same time, the detection table 5 can monitor the pressure or flow changes inside the filter in real time, providing timely data support for the operator. In addition, the presence of the supporting leg 18 and the rubber pad 19 ensures the stability and grip of the device, thereby improving the safety of the device.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
