The outer surface of the rotating shaft 403 is fixed to the rotating frame 404.

[0037] It is known that the protective shell 401 has a rotating hole that is connected to the inner cavity of the protective shell 401. A sealed bearing is fixed on the inner wall of the rotating hole. The inner side of the sealed bearing is fixed to the rotating shaft 403. The sealed bearing and the protective shell 401 cooperate to provide sufficient protection for the stepper motor 402 inside the protective shell 401. The top wall and left side wall of the housing 1 are respectively provided with a water inlet and a water outlet. The top of the rotating shaft 403 is rotatably connected to the top wall of the inner cavity of the housing 1 through a bearing. The rotating frame 404 has multiple snap-fit ​​grooves. Each snap-fit ​​groove is snapped into the filter part 303. Snapping the filter part 303 into the filter part through the snap-fit ​​grooves can improve the overall stability of the filter part 303. The bottom of the rotating frame 404 has multiple through holes that allow liquid to flow smoothly into the water outlet pipe 304. Each through hole is connected to the bottom of the snap-fit ​​groove.

[0038] In addition, the hatch 5 includes an isolation plate 501, a pull ring 502, and a connecting plate 503. The left side and bottom of the isolation plate 501 abut against the top wall and right side wall of the container 1, respectively.

The connecting plate 503 is fixed to the right side of the isolation plate 501. The connecting plate 503 plays a connecting role. The upper thread of the connecting plate 503 is connected with two bolts. The connecting plate 503 is fixed to the isolation plate 501 and the container 1 by the two bolts.

[0039] In this embodiment, when it is necessary to open the hatch 5, two bolts need to be unscrewed first, and then the pull ring 502 can be pulled to quickly open the hatch 5. With the rotation of the rotating mechanism 4, multiple filter elements can be replaced quickly.

[0040] Understandably, the device's filter cartridge is easy to replace, effectively reducing the frequency of replacement while ensuring filtration quality and time, thus effectively reducing labor costs, saving overall expenses, and enhancing the company's market competitiveness.

[0041] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] The working principle of the above embodiments is as follows:

[0043] In operation, first turn valve 302, then start water pump 305 to continuously filter the chemical liquid. When the filter element needs to be replaced, simply start stepper motor 402. Power is transmitted through rotating shaft 403 to rotating frame 404, causing rotating frame 404 to rotate with the filter element, rotating a new filter element to replace the old one. When all filter elements need to be replaced, simply unscrew two bolts and pull ring 502 to open door 5, allowing the worker in front to replace the filter element. After replacing a single filter element, start stepper motor 402. At this time, rotating frame 404 can rotate with the next filter element to be replaced, rotating it to the worker. This device is convenient to use and can replace multiple filter elements at once. After replacement, more time can be used, reducing the frequency of filter element replacement, effectively saving manpower and improving the company's market competitiveness.
