The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0047] As Figures 1-3As shown, the embodiment provides a dust collection device. The dust collection device comprises a dust collection container 100, a filter screen 200, a collection container 300, a cleaning driving assembly 410 and a cleaning member 420.

[0048] As shown, the dust collection container 100 has a first chamber 110. The filter screen 200 is located in the first chamber 110 and divides the first chamber 110 into a pre-filter chamber 111 and a post-filter chamber 112. The filter screen 200 is located on one side of the pre-filter chamber 111 as a receiving surface. An air inlet 140 is arranged on a side wall of the pre-filter chamber 111 opposite to the receiving surface. An air outlet 150 is arranged on a side wall of the post-filter chamber 112. Figure 2 Figure 3 As shown, the dust collection container 100 has a first chamber 110. The filter screen 200 is located in the first chamber 110 and divides the first chamber 110 into a pre-filter chamber 111 and a post-filter chamber 112. The filter screen 200 is located on one side of the pre-filter chamber 111 as a receiving surface. An air inlet 140 is arranged on a side wall of the pre-filter chamber 111 opposite to the receiving surface. An air outlet 150 is arranged on a side wall of the post-filter chamber 112.

[0049] The collection container 300 is arranged in the dust collection container 100 and located on one side of the filter screen 200 in the length direction. The collection container 300 is provided with a residue inlet, and the residue inlet is in communication with the pre-filter chamber 111. The collection container 300 is used to collect the deposits on the receiving surface. The pre-filter chamber 111 is provided with a guide rib 130, and the extension direction of the guide rib 130 is parallel to the length direction of the filter screen 200. The cleaning member 420 is arranged on the guide rib 130 and in contact with the receiving surface along the extension direction of the guide rib 130. The cleaning driving assembly 410 is in transmission connection with the cleaning member 420 to drive the cleaning member 420 to slide.

[0050] When the dust collection device in the embodiment is in operation, dust-containing gas enters the first chamber 110 of the dust collection container 100 from the air inlet 140 on the side wall of the pre-filter chamber 111 opposite to the receiving surface. When passing through the filter screen 200, dust and other particulate matters are blocked on the receiving surface of the filter screen 200 in the pre-filter chamber 111, and the gas passes through the filter screen 200 to enter the post-filter chamber 112, and is discharged from the air outlet 150 on the side wall of the post-filter chamber 112. The gas-solid separation process is completed, and dust collection and air purification are realized.

[0051] As the dust collection is in progress, the deposits will gradually accumulate on the receiving surface. At this time, the cleaning driving assembly 410 drives the cleaning member 420 to slide along the guide rib 130 parallel to the length direction of the filter screen 200. The cleaning member 420 is in contact with the receiving surface during the sliding process, and scrapes the deposits on the receiving surface to fall into the collection container 300 located on one side of the filter screen 200 in the length direction and in communication with the pre-filter chamber 111 through the residue inlet, thereby realizing the cleaning of the filter screen 200.

[0052] ​The dust suction device provided by the embodiment separates the first chamber 110 in the dust collection container 100 into a pre-filter chamber 111 and a post-filter chamber 112 through the filter screen 200. Dust-containing gas enters the pre-filter chamber 111 from the air inlet 140, is filtered through the filter screen assembly, and the dust and other particulate matters are trapped on the receiving surface. Clean gas is discharged from the air outlet 150 of the post-filter chamber 112, realizing efficient gas-solid separation and effective dust collection and purification. The collection container 300 is arranged on one side of the filter screen 200 in the length direction, the slag inlet is in communication with the pre-filter chamber 111, and the cleaning driving assembly 410 drives the cleaning piece 420 to slide along the guide rib 130, automatically scraping the deposits on the receiving surface and collecting the deposits into the collection container 300, so that the filter screen 200 does not need to be manually cleaned frequently, and the continuous working capability and use convenience of the dust suction device are improved. The gas flows from the pre-filter chamber 111 to the post-filter chamber 112 through the filter screen 200, and the collection container 300 is located on one side of the filter screen 200 in the length direction and is not on the main gas flow path. On the one hand, the excessive contact between dust and gas flow during the collection process is avoided, the risk of secondary pollution caused by the collected dust mixing into the gas flow again is reduced, and the effective collection of dust is realized by using the collection container 300. On the other hand, the collection container 300 avoids blocking or interfering with the gas flow through the filter screen 200, and ensures that the gas-solid separation process is efficiently performed.

[0053] The dust collection container 100 can be a hollow container such as a box or a tank. In some embodiments, the dust collection container 100 is a rectangular box.

[0054] As shown in FIGS. 1, 2 and 3, the dust suction device comprises a dust collection container 100, a filter screen 200, a collection container 300, a cleaning driving assembly 410 and a cleaning piece 420. Figure 2 and Figure 3 As shown in FIGS. 1, 2 and 3, the dust suction device comprises a dust collection container 100, a filter screen 200, a collection container 300, a cleaning driving assembly 410 and a cleaning piece 420.

[0055] In some embodiments, the filter screen 200, the cleaning driving assembly 410 and the cleaning piece 420 can each be provided with two, thereby forming two-stage filtration. In some embodiments, the installation mode of the filter screen 200 in the dust collection container 100 can be detachable fixation, facilitating maintenance and replacement.

[0056] As shown in FIGS. 1, 2 and 3, the dust suction device comprises a dust collection container 100, a filter screen 200, a collection container 300, a cleaning driving assembly 410 and a cleaning piece 420. Figure 2As shown, optionally, the four peripheral edges of the filter screen 200 are arranged on the sidewall of the first chamber 110 in the horizontal direction, and divide the first chamber 110 into a pre-filter chamber 111 and a post-filter chamber 112 located below the pre-filter chamber 111. The dust collection device further comprises a partition plate 160, and the dust collection container 100 further has a second chamber 120 separated from the first chamber 110 by the partition plate 160. One end of the filter screen 200 in the length direction is connected to the partition plate 160, and the partition plate 160 is provided with a through hole 161 higher than the filter screen 200. The residue inlet of the collection container 300 is upwardly open and arranged in the second chamber 120, and the residue inlet is located below the through hole 161.

[0057] During operation of the dust collection device in the embodiment, since one end of the filter screen 200 is connected to the partition plate 160, and the partition plate 160 is provided with the through hole 161 higher than the filter screen 200, the cleaning member 420 scrapes the deposits on the bearing surface to the through hole 161 during sliding. After passing through the through hole 161, the deposits fall downward under the action of gravity and fall into the residue inlet of the collection container 300, thereby realizing collection of dust.

[0058] As shown in the drawings, Figure 2 In the embodiment, the second chamber 120 is divided by the partition plate 160, so that the functional division inside the dust collection container 100 is more explicit. The first chamber 110 mainly undertakes the functions of gas-solid separation and cleaning of the filter screen 200, and the second chamber 120 is specially used for collection of deposits. The arrangement of the partition plate 160 and the layout of the collection container 300 in the second chamber 120 provide a path for dust collection through the through hole 161 on the one hand. On the other hand, the partition plate 160 plays a role of blocking the backflow of dust. Even if the airflow in the pre-filter chamber 111 appears a temporary fluctuation, due to the blocking of the partition plate 160, dust is difficult to return to the pre-filter chamber 111 again, effectively avoiding problems such as reduction of filtration efficiency caused by backflow of dust.

[0059] As shown in the drawings, Figure 2 In some embodiments, the second chamber 120 is surrounded by the partition plate 160 and the box wall of the dust collection container 100 in the horizontal direction, and the partition plate 160 and the box wall are oppositely provided with support ribs 162. The collection container 300 is slidingly inserted into the second chamber 120 and is supported by the two support ribs 162, facilitating disassembly and assembly of the collection container 300. In the embodiment, the collection container 300 can be a filter box.

[0060] As shown in the drawings, Figures 2-4As shown, the dust collection device further comprises a water spraying member 430, which is arranged on the side wall of the pre-filter chamber 111 away from the collection container 300 in the length direction of the filter screen 200, and is provided with water spraying holes facing the filter screen 200. The post-filter chamber 112 comprises a water collecting chamber 113, and the collection container 300 is provided with a filter hole communicating with the water collecting chamber 113.

[0061] When the cleaning member 420 cleans the filter screen 200, the water spraying member 430 sprays water synchronously, and the water flow can penetrate into the filter screen pores to effectively flush away stubborn dust, sticky impurities and the like adhered to the filter screen, so as to facilitate the cleaning member 420 to scrape the stubborn dust into the collection container 300. Compared with simply relying on the cleaning member 420 to scrape, the cleaning effect is enhanced, which helps to maintain the high permeability of the filter screen 200, and thus ensures the long-term stable filtering efficiency of the dust collection device.

[0062] In this embodiment, part of the water enters the collection container 300 with the dust, and the water after the filter is discharged into the water collecting chamber 113 due to the filter hole provided on the collection container 300 and the collection container 300 trapping the dust. The other part of the water passes through the filter screen 200 and enters the water collecting chamber 113 of the post-filter chamber 112, thereby realizing the collection and recovery of the water spraying.

[0063] In some embodiments, the water spraying member 430 is a water spraying pipe, and a plurality of water spraying holes are arranged on the water spraying pipe at intervals. The water spraying pipe can extend along the width direction of the filter screen 200, and under the cooperation of the movement of the cleaning member 420 in the length direction, the water flow can fully cover the filter screen 200. The water spraying pipe can be embedded on the side wall of the dust collecting container 100 in the horizontal direction, which reduces dust pollution and improves compactness. The water spraying pipe can be arranged on one side of the pre-filter chamber 111 of the filter screen 200.

[0064] Optionally, the four peripheral edges of the filter screen 200 are arranged on the side wall of the first chamber 110 in the horizontal direction, and the first chamber 110 is divided into the pre-filter chamber 111 and the post-filter chamber 112 located below the pre-filter chamber 111. The dust collection device further comprises a flow guide plate 170, which is arranged in the post-filter chamber 112 and is located below the filter screen 200 at intervals. The upper end of the flow guide plate 170 is connected to the side wall of the post-filter chamber 112 in the horizontal direction, and the flow guide plate 170 extends from top to bottom to the inlet of the water collecting chamber 113. The air suction port 150 is higher than the upper end of the flow guide plate 170 and is arranged on the side wall of the post-filter chamber 112 in the horizontal direction.

[0065] As shown, Figure 2As shown, in the present embodiment, the air suction port 150 is higher than the upper end of the flow guide plate 170. The flow guide plate 170 can guide the water flow falling from the filter screen 200 to flow more smoothly along the inclined surface of the flow guide plate 170 into the water collecting chamber 113. The above arrangement effectively prevents the water in the water collecting chamber 113 from flowing backward into the air suction port 150 under the action of air flow, thereby protecting the air suction equipment from erosion and damage by water and ensuring stable operation of the air suction system.

[0066] As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150. Figure 2 As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150.

[0067] As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150. Figures 2-4 As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150.

[0068] The rotating drive member, as a power output end, transmits power to the cleaning member 420 through precise meshing of the drive gear and the rack 411. When the rotating drive member drives the drive gear to rotate, the drive gear rolls on the rack 411, thereby driving the moving rod 421 to move linearly along the guide rib 130. At the same time, the rotating drive member also drives the cleaning roller 422 to rotate at an appropriate speed through the gear set transmission member. The rotating drive member not only realizes the movement of the cleaning member 420 but also realizes the rotation of the cleaning roller 422, which is synchronous on one hand and has good integration and saves components on the other hand. Rolling cleaning not only increases the cleaning area but also reduces the frictional resistance between the cleaning member 420 and the filter screen 200, thereby reducing the degree of wear of the filter screen 200.

[0069] As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150. Figure 4 As shown in FIG. 4, the dust collection device further comprises a water collecting chamber 113, which is arranged on the bottom of the filter screen 200 and is connected to the air suction port 150.

[0070] like Figure 4 As shown, in some embodiments, the filter screen 200 is provided with a limiting groove 201, and the rack 411 is formed on the inner wall of the limiting groove 201. The drive gear moves within the limiting groove 201 to ensure accuracy.

[0071] like Figure 4 As shown, in some embodiments, the gear transmission includes a driving gear 412 and a driven gear 413 connected in a transmission relationship. The driving gear 412 and the drive gear are mounted on the same rotating shaft, while the rotating shaft of the driven gear 413 is connected to the cleaning roller 422. The drive gear rotates, causing it to roll along the rack 411, which in turn moves the moving rod 421. Simultaneously, the driving gear 412 drives the driven gear 413 to rotate, causing the cleaning roller 422 to rotate. The number of teeth on the driving gear 412 can be greater than the number of teeth on the driven gear 413, thereby accelerating the transmission and increasing the rotational speed of the cleaning roller 422.
