[0028] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0029] Embodiment 1: In order to solve the problems in the prior art that the existing filter structure is simple, the filtering effect is poor, and it is cumbersome to replace the filter element 14 when it is needed, it is not convenient to quickly replace the filter element 14, and it is time-consuming and laborious, the following scheme is disclosed, including a filter body 1, the bottom of the filter body 1 is connected with the drain port 8, and the outer side of the drain port 8 is provided with a filter chamber 9; it also includes: a filter element 14 is provided inside the filter chamber 9, and a sealing ring 15 is bonded to the upper surface of the filter element 14, and the sealing ring 15 and the limit block 16 fit together, and the limit block 16 is fixed to the inner wall of the filter chamber 9, and a clamping block 17 is provided below the filter element 14, and the lower surface of the clamping block 17 is an inclined structure, and a sliding connection is formed between the clamping block 17 and the filter chamber 9, and a return spring 18 is fixed to the outer end of the clamping block 17, and the outer end of the return spring 18 is fixed to the filter chamber 9;

[0030] When the filter element 14 needs to be replaced, it is only necessary to manually push the block 17 outward, so that the block 17 slides into the filter chamber 9, so that the block 17 no longer limits the filter element 14, and the filter element 14 can fall downward, and then a new filter element 14 is placed in the filter chamber 9, so that the filter element 14 contacts the block 17, and by continuing to apply thrust to the filter element 14, the block 17 is forced to slide outward, so that the filter element 14 can slide above the block 17, and at this time the block 17 is no longer restricted. The force is then driven by the elastic force of the reset spring 18 to reset the block 17, so that the block 17 can limit the engagement of the filter element 14, and the filter element 14 can also drive the sealing ring 15 to fit with the limit block 16, so as to achieve a sealing effect, and the setting of the limit block 16 can limit the filter element 14, so that the filter element 14 is always between the limit block 16 and the block 17. The above-mentioned structural setting makes it easy to quickly replace the filter element 14, thereby improving the work efficiency and saving time and effort;

[0031] Embodiment 2: Different from Embodiment 1, this embodiment facilitates opening the filter chamber 9 without using tools to unscrew the threaded rods 13 one by one, saving time and effort.

[0032] The filter chamber 9 is provided with an upper and lower two layers. When the filter chamber 9 needs to be opened, it is only necessary to rotate the gear ring 11, thereby causing the gear ring 11 to rotate and drive the multiple sets of gears 12 meshing inside to rotate together. The gear 12 rotates, thereby causing the gear 12 to drive the threaded rod 13 fixed in the middle to be screwed out of the lower connecting ring 10, thereby allowing the filter chamber 9 to be opened, and then the impurities on the filter element 14 can be cleaned. After the cleaning is completed and the filter element 14 is installed, the lower filter chamber 9 is placed under the upper filter chamber 9, and then the gear ring 11 is rotated, thereby causing the gear ring 11 to drive the multiple sets of gears 12 to rotate, thereby causing the gear 12 to drive the threaded rod 13 to rotate, so that the threaded rod 13 is screwed into the lower connecting ring 10, thereby realizing the threaded connection with the lower connecting ring 10, thereby fixing the filter chamber 9, thereby facilitating the opening of the filter chamber 9, and there is no need to use tools to unscrew the threaded rod 13 one by one, which saves time and effort and achieves the effect of quickly cleaning the impurities on the filter element 14.

[0034] Moreover, the filter body 1 is supported by the ear-type support 2 and the platform, and then the filter body 1 is hung. At this time, the ear-type support 2 can be fixed by screws, and liquid potassium formate is sent into the filter body 1 through the liquid inlet 3. The liquid potassium formate is filtered by the filtering mechanism 5 on the upper surface of the support plate 4 to block impurities outside the filtering mechanism 5, and the clean liquid is discharged through the liquid outlet 6. When the pressure difference at the liquid outlet 6 reaches the set value, backwashing is performed through the backwashing port 7, and then impurities on the outer side of the filtering mechanism 5 are washed off, and then discharged through the drain port 8.
