DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 A multi-layer flat membrane water purification microfiltration device shown in the figure comprises a treatment box 1, the top and side of the treatment box 1 are respectively fixed with a water inlet and a water outlet, a plurality of mounting holes are opened on the side of the treatment box 1, and filter screens 2 are movably arranged in the plurality of mounting holes, two rotating rods 8 are rotatably installed on the relative inner walls of the treatment box 1, one end of each of the two rotating rods 8 is installed with a handle 10, and a rotating plate 9 is sleeved on each of the two rotating rods 8, and four U-shaped blocks 3 are installed on the relative inner walls of the treatment box 1, wherein the tops of three of the U-shaped blocks 3 are respectively opened with movable holes, and fixed rods 5 are slidably installed on the three movable holes, and sealing plates 4 are installed on the bottom ends of the three fixed rods 5, wherein the top ends of the two fixed rods 5 are respectively abutted against the bottoms of two of the sealing plates 4, and a movable plate 6 is installed on the top of the other fixed rod 5, wherein the top of one of the U-shaped blocks 3 is opened with a placement groove adapted to the movable plate 6, and the top of one of the sealing plates 4 is provided with an elastic mechanism.

[0023] With the above structure, when in use, first connect the water inlet to the external device, and then filter through multiple filter screens 2 in sequence. When the filter screen 2 needs to be replaced after long-term filtration, first turn one of the handles 10. The rotation of the handle 10 will cause the rotating rod 8 to rotate. The rotation of the rotating rod 8 will cause the rotating plate 9 to rotate. When the rotating plate 9 contacts the movable plate 6, the rotating plate 9 continues to rotate to cause the movable plate 6 to descend. The descent of the movable plate 6 will cause the blocking plate 4 to descend through one of the fixed rods 5. The descent of one of the blocking plates 4 will cause the other two fixed rods 5 to descend. The sealing plates 4 descend in sequence, and when the movable plate 6 moves to the placement groove, the rotating plate 9 seals the top of it. At the same time, multiple sealing plates 4 divide the processing box 1 into two parts. At this time, water continues to flow and filter from the other end, and then the filter 2 is replaced and maintained. When replaced, the rotating plate 9 is reset by the handle 10. When the rotating plate 9 does not squeeze the movable plate 6, the sealing plate 4 is reset under the action of the elastic mechanism, and then the above operation is repeated to replace the filter 2 on the other side, so that the filter 2 can be replaced without stopping the filtration, which is convenient for use.

[0024] like Figure 4 As shown, a fixed block 13 is installed on the side of the processing box 1, and movable grooves are opened on the sides of the fixed block 13 that are away from each other. Screw rods 14 are rotatably installed on the relative inner walls of the two movable grooves. The tops of the two screw rods 14 extend to the outside of the fixed block 13 and are respectively installed with knobs 15. Three blocking blocks 16 are threadedly sleeved on the two screw rods 14. The advantage of this arrangement is that through the arrangement of the fixed block 13, the screw rod 14, the knob 15 and the blocking block 16, it is convenient to block and limit the filter 2 to prevent movement.

[0025] Specifically, the knob 15 is rotated, and the rotation of the knob 15 drives the screw rod 14 to rotate, and the rotation of the screw rod 14 causes the blocking block 16 to move, thereby blocking the three mounting holes, thereby limiting the three filter screens 2 on one side at the same time to prevent movement during use.

[0026] like Figure 4 As shown, guide rods 17 are installed on the relative inner walls of the two movable grooves, and guide holes are opened at the bottoms of the multiple blocking blocks 16. One of the guide rods 17 passes through the multiple guide holes located on the same side in sequence. The advantage of this arrangement is that the blocking block 16 can move in the horizontal direction through the setting of the guide rod 17.

[0027] like Figure 2 As shown, the sides of the two knobs 15 are installed with ropes 18, and the top of the fixed block 13 is installed with two rods 19. The advantage of this arrangement is that the movement of the blocking block 16 can be avoided by the arrangement of the ropes 18 and the rods 19.

[0028] Specifically, after the blocking is completed, the sleeve rope 18 is sleeved on the sleeve rod 19, and the knob 15 cannot be rotated at this time, so that the screw rod 14 cannot be rotated, thereby preventing the blocking block 16 from moving.

[0029] like Figure 3 As shown, the elastic mechanism includes multiple springs 7 installed on the top of the blocking plate 4, and the other ends of the multiple springs 7 are installed on the top inner wall of one of the U-shaped blocks 3. The advantage of this arrangement is that, through the arrangement of the springs 7, when the rotating plate 9 does not squeeze the moving plate 6, the bottom blocking plate 4 is reset under the action of the springs 7, and the reset of the bottom blocking plate 4 will reset the other two blocking plates 4 through the fixing rod 5.

[0030] like Figure 2 As shown, through holes are provided on the sides of the two handles 10, and fixing bolts 11 are movably provided in the two through holes. A plurality of threaded holes are provided on the side of the processing box 1, and the ends of the two fixing bolts 11 are respectively threadedly installed in two of the threaded holes. The advantage of such an arrangement is that the fixing bolts 11 facilitate the fixation of the handle 10 to avoid the handle 10 rotating and causing one side to be closed during use.

[0031] like Figure 3 As shown, the opposite inner walls of the processing box 1 and the sides of the three U-shaped blocks 3 which are away from each other are installed with support plates 12. The advantage of such an arrangement is that the filter screen 2 can be easily supported by the arrangement of the support plates 12.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
