[0007] A pleated filter element with high filtration flux comprises a pleated filter element body, a lower bearing seat is arranged at the bottom of the pleated filter element body, a lower end cover is fixedly connected to the bottom of the lower bearing seat, a boss is arranged at the top of the pleated filter element body, a plurality of extrusion blocks are arranged inside the boss, and the plurality of extrusion blocks are arranged evenly distributed, a sleeve is arranged at the outside of the boss, a limited position mounting cover is arranged at the top of the sleeve, an upper bearing seat is connected to the top of the limited position mounting cover, an upper end cover is connected to the top of the upper bearing seat, a filter element is arranged below the sleeve, and the outside of the pleated filter element body is divided into a plurality of folded layers by folding strips.

[0008] As a preferred solution of the utility model, the overall internal size of the boss is smaller than the overall size of the filter element, and the filter element is made of cotton material.

[0009] As a preferred solution of the utility model, a plurality of clamping blocks are further arranged on the outer side of the sleeve, a clamping groove for use with the clamping blocks is provided on the upper side of the folded filter element body, and the bottom of the sleeve is clamped with the clamping blocks and the clamping grooves.

[0010] As a preferred solution of the utility model, a notch for use with the boss is provided at the bottom of the sleeve, and the boss is integrally plugged into the notch.

[0011] As a preferred solution of the utility model, a storage notch is provided on the top of the upper end cover, and a rotatable handle is provided inside the storage notch.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, a pleated filter element with high filtration flux is provided. When the pleated filter element is used, the limit mounting cover and the sleeve end can be lifted upwards, thereby driving the filter element to be removed from the inside of the pleated filter element body. Since the internal size of the boss is smaller than the overall size of the filter element and the filter element is made of soft cotton material, the filter element can be squeezed by using the squeezing block inside the boss to squeeze out the sewage inside the filter element. Then, water is added from the water inlet of the equipment to flush out the squeezed sewage inside the pipe, thereby achieving the purpose of cleaning the filter element and the equipment pipe.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution:

[0020] A pleated filter element with high filtration flux comprises a pleated filter element body 1, a lower bearing seat 2 is arranged at the bottom of the pleated filter element body 1, a lower end cover 3 is fixedly connected to the bottom of the lower bearing seat 2, a boss 4 is arranged at the top of the pleated filter element body 1, a sleeve 5 is arranged at the outside of the boss 4, a limited position mounting cover 6 is arranged at the top of the sleeve 5, an upper bearing seat 7 is connected to the top of the limited position mounting cover 6, an upper end cover 8 is connected to the top of the upper bearing seat 7, a filter element 9 is arranged below the sleeve 5, and the outside of the pleated filter element body 1 is divided into multiple folded layers 11 by a folding strip 10.

[0021] Specifically, a plurality of extrusion blocks 12 are arranged inside the boss 4, and the plurality of extrusion blocks 12 are evenly distributed; the overall size of the interior of the boss 4 is smaller than the overall size of the filter element 9, and the filter element 9 is made of cotton material;

[0022] In this embodiment, since the internal size of the boss 4 is smaller than the overall size of the filter element 9 and the filter element 9 is made of soft cotton material, the filter element 9 can be squeezed by the squeezing block 12 inside the boss 4 to squeeze out the sewage inside the filter element 9.

[0023] Specifically, a plurality of blocks are provided on the outer side of the sleeve 5, a slot 13 for use with the block is provided on the upper side of the folded filter element body 1, and the bottom of the sleeve 5 is connected with the slot 13 through the block; a notch for use with the boss 4 is provided at the bottom of the sleeve 5, and the boss 4 is connected with the boss 4 as a whole through the notch;

[0024] In this embodiment, the upper end cover 8, the upper bearing seat 7 and the filter element 9 can be separated from the inside of the folded filter element body 1 through the connection between the clamping block and the clamping slot 13 and the connection between the boss 4 and the notch.

[0025] Preferably, a storage notch 14 is provided at the top of the upper end cover 8, and a rotatable handle 15 is provided inside the storage notch 14. The handle 15 is opened by a rotating structure, so that the upper end cover 8 can be easily picked up.

[0026] Working principle: When using the folded filter element with high filtration flux, the handle 15 is opened by rotating the structure to pick up the upper end cover 8. At the same time, through the connection between the block and the slot 13 and the connection between the boss 4 and the slot, the upper end cover 8, the upper bearing seat 7 and the filter element 9 can be separated from the inside of the folded filter element body 1. During the separation process, since the internal size of the boss 4 is smaller than the overall size of the filter element 9, and the filter element 9 is made of soft cotton material, the extrusion block 12 inside the boss 4 can be used to extrude the filter element 9 to squeeze out the sewage inside the filter element 9, and then water is added from the water inlet of the equipment to flush out the squeezed sewage inside the pipe, thereby achieving the purpose of cleaning the filter element and the equipment pipe, which has certain promotion value.
