DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with 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 of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1-3 The utility model provides a technical solution: a puncture-proof composite filter bag structure, comprising a mounting plate 1, a protective filter assembly 200 for filtering and protecting the filter structure is installed at the bottom of the mounting plate 1, and a collection assembly 300 for collecting dust is installed at the bottom of the protective filter assembly 200;

[0024] By using the mounting plate 1, the protective filter assembly 200 and the collection assembly 300 in coordination, in actual use, it is possible to effectively prevent large particles of impurities from impacting the filter bag with the help of the impact force of the gas and causing the filter bag body to be punctured. In addition, during the transportation of the composite filter bag structure, it is also possible to prevent the filter bag from being punctured by other sharp objects. At the same time, it is also possible for the staff to clean the filter bag more conveniently, thereby improving the practicality of the puncture-proof composite filter bag structure.

[0025] In this embodiment, the protective filter assembly 200 is a structure used for filtering and protecting the filter structure.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the protective filtering assembly 200 includes a protective net 201 fixed to the bottom of the mounting plate 1, a bottom plate 202 is fixed to the bottom of the protective net 201, a through hole 203 is fixed to the top of the mounting plate 1, a steel ring 204 is fixed inside the through hole 203, four steel bars 205 are fixed to the bottom of the steel ring 204, a cross rod 206 is fixed between the four steel bars 205 on the side away from the protective net 201, a first protective layer 207 is fixed to the bottom of the mounting plate 1, a second protective layer 208 is fixed inside the first protective layer 207, a base fabric layer 209 is fixed inside the second protective layer 208, and two limit plates 210 are fixed to the top of the bottom plate 202.

[0027] It should be noted that the tops of the second protective layer 208 and the base fabric layer 209 are fixed to the bottom of the mounting plate 1 to ensure that the second protective layer 208 and the base fabric layer 209 can be effectively fixed to achieve a filtering effect.

[0028] In addition, the protective net 201 is an annular mesh plate, and the inner diameter of the protective net 201 is larger than the distance between the opposite sides of the two limiting plates 210, ensuring that the protective net 201 can effectively protect the first protective layer 207, the second protective layer 208 and the base fabric layer 209.

[0029] In addition, the first protective layer 207 and the second protective layer 208 are both polytetrafluoroethylene films, which are polymer materials that are lighter than metal materials and have the advantages of non-stickiness, high chemical resistance, and extremely low friction coefficient. The first protective layer 207 and the second protective layer 208 are staggered and stacked so that the directions of the micropores of the first protective layer 207 and the second protective layer 208 are crossed, thereby achieving the expected filtering effect and effectively preventing it from being punctured by other sharp objects.

[0030] In this embodiment, the collecting assembly 300 is a structure for collecting dust for easy disposal.

[0031] like Figure 1 and Figure 3 As shown, the collecting assembly 300 includes two movable plates 301 slidably connected to the bottom of the base plate 202, two slide grooves 302 are provided at the bottom of the base plate 202, springs 303 are fixed on opposite sides of the two movable plates 301, plug-in rods 304 are fixed on opposite sides of the two movable plates 301, two baffles 305 are fixed inside the base plate 202, and a collecting frame 306 is slidably connected inside the base plate 202.

[0032] It should be noted that the adjustable distance of the movable plate 301 inside the slide groove 302 is greater than the adjustable distance of the plug-in rod 304 inside the collection frame 306, ensuring that the movement of the plug-in rod 304 driven by the movable plate 301 can release the limit of the collection frame 306 by the plug-in rod 304.

[0033] In addition, the opposite ends of the two plug-in rods 304 penetrate the bottom plate 202 and the collection frame 306 in sequence and extend to the interior of the collection frame 306 to be plugged into the collection frame 306, ensuring that the plug-in rods 304 can be stably and effectively plugged into the collection frame 306, and the top of the collection frame 306 is in close contact with the bottom of the limiting plate 210, ensuring that the collection frame 306 can be effectively fixed.

[0034] In addition, the width of the movable plate 301 is equal to the width of the slide groove 302, so that the movable plate 301 slides more stably in the slide groove 302, and the height of the movable plate 301 is greater than the height of the slide groove 302, ensuring that the movable plate 301 can slide conveniently.

[0035] The working principle of the above embodiment is:

[0036] In actual use, the protective net 201 can effectively filter large particles of impurities, thereby preventing the large particles of impurities from scratching the filter bag, and the first protective layer 207 and the second protective layer 208 are both polytetrafluoroethylene films, which are polymer materials that are lighter than metal materials and have the advantages of non-stickiness, high chemical resistance, and extremely low friction coefficient. The first protective layer 207 and the second protective layer 208 are staggered and stacked, so that the micropores of the first protective layer 207 and the second protective layer 208 are crossed, so as to achieve the expected filtering effect while effectively preventing it from being punctured by other sharp objects, and the strength of the filter bag can be further improved by the steel bar 205 and the cross rod 206, and the collection The frame 306 effectively collects dust and the like. When cleaning is needed, it is convenient to pull the two movable plates 301 to the left and right sides, thereby driving the connecting rod 304 to move left and right. At this time, the spring 303 is in a compressed state, so that the connecting rod 304 loses the limit on the collection frame 306, and the collection frame 306 can be taken out from the inside of the bottom plate 202, so as to facilitate dust cleaning. After cleaning, the collection frame 306 is put back into the bottom plate 202, and the movable plate 301 is released. Under the action of the restoring elastic force of the spring 303, the connecting rod 304 is re-connected with the collection frame 306, thereby fixing the collection frame 306. The operation is relatively simple and there is no need to disassemble and assemble the entire filter bag structure.

[0037] Compared with the prior art, the puncture-proof composite filter bag structure, through the coordinated use of the mounting plate 1, the protective filter assembly 200 and the collection assembly 300, can effectively prevent large particles of impurities from impacting the filter bag with the help of the impact force of the gas, causing the filter bag body to be punctured during actual use. It can also prevent the filter bag from being punctured by other sharp objects during the transportation of the composite filter bag structure. At the same time, it can also make it more convenient for the staff to clean the filter bag, thereby improving the practicality of the puncture-proof composite filter bag structure and solving the problem of low practicality of the existing composite filter bag structure.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
