[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The utility model embodiment provides Figure 1-Figure 12 As shown, in this embodiment, a dust removal and filtration device comprises an exhaust pipe 1, a filter bag 3, a tray 5 and a bottom plate 7. The top of the exhaust pipe 1 is detachably connected to a top plate 2, and a plurality of exhaust ports are provided on the top plate 2.

[0037] There are multiple filter packs 3, multiple connecting strips 11 are arranged in the filter packs 3, and multiple filter packs 3 are arranged in a ring array at the bottom of the top plate 2. The other end of the filter pack 3 is provided with a clamping assembly 4. Multiple nozzles 9 are arranged on the side wall of the exhaust pipe 1, and the multiple nozzles 9 are connected to the exhaust pipe 1.

[0038] The tray 5 is rotatably connected to the exhaust pipe 1, and a plurality of limit assemblies 6 capable of being installed in cooperation with the clamping assembly 4 are provided on the outer side wall of the tray 5;

[0039] The chassis 7 is rotatably connected to the exhaust pipe 1 , and a plurality of springs are arranged on the top of the chassis 7 , and the other ends of the springs are all connected to the bottom of the tray 5 .

[0040] It should be noted that, since the existing sheet filter element cannot be disassembled, the dust accumulated in the gap of the filter element cannot be thoroughly cleaned, which leads to a gradual shortening of the later cleaning cycle, reduces the service life, shortens the cycle of replacing the filter element, and increases the cost of use. In order to solve this problem, a filter bag 3, a clamping assembly 4, a limiting assembly 6 and a nozzle 9 are provided in the present scheme. Through the clamping cooperation between the filter bag 3 and the clamping assembly 4, and the hinged relationship between the top of the filter bag 3 and the top plate 2, when the clamping assembly 4 releases the limit on the filter bag 3, the filter bag 3 can be unfolded, and the nozzle 9 is used to blow air on the surface of the filter bag 3, so that the dust attached to the gap between two adjacent filter bags 3 is cleaned, thereby improving the cleaning efficiency and cleaning quality.

[0041] Specifically, during operation, the gas is filtered by the filter bag 3 and then discharged through multiple exhaust ports opened on the top plate 2. The dust is filtered by the filter bag 3 and then accumulated in the gap between the two filter bags 3.

[0042] When cleaning is required, manually separate the limit assembly 6 from the clamping assembly 4, release the positioning restriction of the plastic clamp 62 on the vertical plate 41, and then thread the first thread groove 101 with the air pump output end, input high-pressure gas into the first thread groove 101 through the air pump, and the gas is sprayed out through the nozzle 9 to blow the filter bag 3, and the unfolded filter bag 3 can make the dust and impurities stuck in the gap fall off, and the filter bag 3 can be thoroughly cleaned with the blowing of the nozzle 9. Since the exhaust pipe 1 is rotatably connected to the top plate 2 and the bottom plate 7, the filter bag 3 can be pushed and rotated during cleaning, and manually knocked by personnel to thoroughly clean the filter bag 3, so that dust can be prevented from getting stuck in the gap of the filter bag 3 and making it impossible to clean during the cleaning process.

[0043] In a further preferred embodiment of the present invention, Figure 6 and Figure 8 As shown, the clamping assembly 4 includes a vertical plate 41, a clamping block 42 and a raised strip 43. One end of the vertical plate 41 is connected to the bottom of the filter bag 3, and the other end of the vertical plate 41 is connected to the clamping block 42. Two raised strips 43 are provided, and the two raised strips 43 are respectively connected to the side walls of the vertical plate 41. The limiting assembly 6 includes a clamping plate 61 and a plastic clamping member 62. The cross-section of the clamping plate 61 is L-shaped. One end of the clamping plate 61 is connected to the plastic clamping member 62.

Two symmetrically arranged inclined surfaces are provided on one side of the clamping groove, and two grooves that cooperate with the raised strip 43 are provided on the side wall of the clamping groove.

[0044] In this embodiment, after the block 42 is clamped in the plastic clamping sleeve 51, the clamping plate 61 is rotated at the center of the hinge point with the connecting member 52, so that the clamping plate 61 is lifted and then clamped with the vertical plate 41 through the clamping groove set on the limiting component 6. Since the plastic clamping member 62 is made of plastic material and has a certain ductility, it can clamp the raised strip 43 to achieve positioning of the filter bag 3. This clamping installation method is efficient and fast, which improves the convenience of cleaning the filter bag 3 and reduces the difficulty of cleaning.

[0045] In a further preferred embodiment of the present invention, Figure 7 As shown, a feed port is provided at one end of the filter bag 3 , a rubber plug 31 is provided in the feed port, an end plate 12 is provided at one end of the filter bag 3 , a rubber strip 121 is provided on the end plate 12 , and the end plate 12 is hinged to the top plate 2 .

[0046] In this embodiment, by manually opening the rubber plug 31, the activated carbon in the filter bag 3 can be replaced through the feed port, thereby increasing the service life of the filter bag 3, improving the filtering effect, and achieving the function of filtering impurities such as harmful gases in addition to filtering dust.

[0049] When further filtering and improving the filtering effect are needed, the inner filter layer 8 can be installed on the top of the tray 5. After the dust is filtered by the filter bag 3, it can be filtered again by the inner filter layer 8 to achieve higher filtering adjustment requirements.

[0050] In a further preferred embodiment of the present invention, Figure 9-10 As shown, a sealing rubber ring 10 is provided on the top of the top plate 2, and an annular groove is provided on the top of the sealing rubber ring 10.

[0051] In this embodiment, when connected with other devices through the sealing rubber ring 10, the sealing effect of the connection can be improved, the sealing of the connection can be guaranteed, and gas leakage can be avoided.

After being connected to the chassis 7 through the second thread groove 102, the connection stability can be improved.

[0054] In a further preferred embodiment of the present invention, Figure 1-Figure 8 As shown, a plurality of positioning grooves cooperating with the clamping blocks 42 are formed on the inner bottom wall of the chassis 7 .

[0055] In this embodiment, when the bottom of the block 42 fits into the positioning groove, the block 42 can be positioned and guided to limit the position of the block 42, thereby avoiding displacement of the block 42 and causing large gaps between the filter bags 3.

[0056] In a further preferred embodiment of the present invention, Figure 2-Figure 8 As shown, one end of the connecting strip 11 is connected to the end plate 12 , and the other end of the connecting strip 11 is connected to the vertical plate 41 . The connecting strip 11 is located in the filter bag 3 .

[0057] In this embodiment, the main function of the connecting strip 11 is to connect the end plate 12 and the vertical plate 41 so that the filter bag 3 can maintain a strip shape and avoid bending.
