DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figures 1-6 The utility model provides a wear -resisting dust removal filter bag, including interlayer 1.

[0028] Refer to Figure 3 And Figure 4As shown, the outer wall of the partition layer 1 is attached with a dismounting structure 2, which comprises a first mounting ring 201, a second mounting ring 202, a third mounting ring 203, a cavity 204, a limiting block 205, a connecting rod 206, a handle 207 and a rotating block 208. The first mounting ring 201 is attached to the outer wall of the partition layer 1, and the bottom surface of the first mounting ring 201 is attached with the second mounting ring 202. The bottom surface of the second mounting ring 202 is attached with the third mounting ring 203. The inner portion of the second mounting ring 202 is provided with the cavity 204, and the inner wall of the cavity 204 is fixed with the limiting block 205. The inner portion of the limiting block 205 is penetrated by the connecting rod 206, and the top portion of the connecting rod 206 is provided with the handle 207. The bottom portion of the connecting rod 206 is fixed with the rotating block 208. The second mounting ring 202 is attached to the partition layer 1, and the third mounting ring 203 is attached to the partition layer 1. The first mounting ring 201 is in the shape of a ring, and the first mounting ring 201 and the third mounting ring 203 are symmetrically distributed. The limiting block 205 is not connected with the connecting rod 206. The extending end of the connecting rod 206 penetrates the second mounting ring 202 and is not connected therewith. The extending end of the connecting rod 206 penetrates the first mounting ring 201 and is not connected therewith. The handle 207 is rotationally connected with the rotating block 208.

[0029] The first mounting ring 201, the second mounting ring 202 and the third mounting ring 203 are all rubber layers, which have good flexibility and adsorption. After the partition layer 1 is pulled to make the third mounting ring 203 deform, the third mounting ring 203 can be installed. When the filter bag needs to be replaced after being used for a period of time, the position of the third mounting ring 203 corresponding to the rotating block 208 is thinner than other positions. The handle 207 can be used to break the third mounting ring 203 by using the sharp end of the rotating block 208, so that air enters the outside of the third mounting ring 203. Then, the partition layer 1 can be pulled to be removed, so that the device has the function of being easy to dismount.

[0030] Referring to Figure 6 As shown, the bottom surface of the partition layer 1 is fixed with a filter structure 3, which comprises a first filter layer 301, a second filter layer 302, a third filter layer 303 and a fourth filter layer 304. The first filter layer 301 is fixed to the bottom surface of the partition layer 1. The two sides of the first filter layer 301 are both fixed with the second filter layer 302. The inner wall of the second filter layer 302 is attached with the third filter layer 303. The outside of the third filter layer 303 is attached with the fourth filter layer 304. The second filter layer 302 is fixedly connected with the partition layer 1. The third filter layer 303 is fixedly connected with the partition layer 1. The fourth filter layer 304 is fixedly connected with the partition layer 1. The first filter layer 301 is horizontally distributed. The second filter layer 302 is vertically distributed. The first filter layer 301 is attached with the third filter layer 303. The first filter layer 301 is attached with the fourth filter layer 304. The second filter layer 302 is attached with the fourth filter layer 304. The third filter layer 303 and the fourth filter layer 304 are cross-distributed.

[0031] The first filter layer 301, the second filter layer 302, the third filter layer 303, and the fourth filter layer 304 are all made of special fiber materials, including but not limited to polyester staple fiber, PPS fiber, and aramid fiber. These materials have good wear resistance and corrosion resistance, which can maintain the integrity of the filter bag and prevent harmful substances in the air from corroding the filter bag during long-term use. Furthermore, through their fine weaving process, they have good air permeability and can effectively capture and separate dust particles in the air, thus enabling the device to have good wear resistance and filtration performance.

[0032] In summary, as Figures 1-6 As shown, in use, the filter structure 3 is passed through the area to be filtered, with the partition 1 placed on top of the mounting opening. Pulling the bottom end of the partition 1 causes the third mounting ring 203 to deform, placing its top surface on the bottom surface of the mounting opening. The first mounting ring 201 is placed on the top surface of the mounting opening. Pressing the top and bottom ends of the partition 1 expels air from between the second mounting ring 202 and the mounting opening, thus ensuring a tight fit between the second mounting ring 202 and the mounting opening. The first filter layer 301, second filter layer 302, and third filter layer 302 are then in place. All 03 are located at the bottom of the installation port, thereby filtering impurities into the interior of the filter structure 3. After the filter structure 3 is full of impurities, turn the handle 207. The handle 207 drives the connecting rod 206 to rotate inside the limiting block 205, thereby driving the rotating block 208 to slide inside the cavity 204. The sharp end of the rotating block 208 pierces through the cavity 204 and punctures the second mounting ring 202, allowing air to enter between the second mounting ring 202 and the installation port, and squeezing and deforming the second mounting ring 202. Pull the partition 1 again to remove it.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
