Detailed Embodiments

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1: The present invention provides an automatic dust removal device, as Figures 1 to 8 shown, including: a housing 1, a collection cart 2 is movably connected inside the housing 1, a diversion interface 3 is fixedly installed in the middle of the outer surface of the housing 1, bellows 4 are symmetrically fixedly installed at the top of the diversion interface 3, and a suction hood 5 is fixedly installed at one end of the bellows 4; Inside the housing 1, a corrugated cover 13 is installed at a position on one side of the diversion interface 3. One end of the corrugated cover 13 is fixedly installed with a filtering structure 6. The filtering structure 6 includes a barrier cover 61 vertically movably connected inside the housing 1. A conical cover 62 is fixedly installed inside the barrier cover 61. A plurality of fitting holes are opened at the bottom of the outer surface of the conical cover 62. A filter element 63 is snap-fitted at the top of the conical cover 62. A collection cover 65 is fixedly installed at the bottom end of the barrier cover 61. A discharge pipe 66 is rotatably connected in the middle of the collection cover 65. A connecting pipe 67 is fixedly installed on the outer side of the discharge pipe 66. Collection boxes 68 are installed at the outer side and the inner bottom end positions of the filter element 63 at the top of the connecting pipe 67 and the discharge pipe 66. A concave plate 69 is fixedly installed at the top of the collection box 68. A brush 611 is installed inside the concave plate 69.

[0021] As Figure 6 and Figure 7 shown, a support ring 64 is fixedly installed between the bottom end of the barrier cover 61 and the top end of the collection cover 65. A vertical plate 610 is installed inside the concave plate 69. The brush 611 is fixedly installed inside the vertical plate 610. The number of the concave plates 69 is set to two in total. The vertical plates 610 inside the two concave plates 69 are arranged staggeredly; Due to the staggeredly arranged vertical plates 610, the brushes 611 are arranged staggeredly. The filter element 63 is cleaned staggeredly by the staggeredly arranged brushes 611, so that the inside of the filter element 63 is cleaned multiple times, and the problem of mutual adhesion between the two brushes 611 during the cleaning process is prevented.

[0022] As Figure 6 and Figure 7 shown, a limiting ring 612 is sleeved and installed at a position inside the conical cover 62 on the outer side of the discharge pipe 66. A plurality of balls 613 are equidistantly embedded at the bottom end of the limiting ring 612. A stirring blade 614 is fixedly installed at the top end of the discharge pipe 66; Under the action of the limiting ring 612, the discharge pipe 66 is limited. At the same time, through the balls 613 at the bottom end of the limiting ring 612, the friction between the limiting ring 612 and the conical cover 62 is reduced, so as to facilitate the rotation of the limiting ring 612.

[0023] As Figure 6 and Figure 7As shown, the central line of the stirring blade 614 coincides with the central line of the ground, and the central line of the barrier cover 61 coincides with the central line of the ground. An arc-shaped ring is welded to the bottom end of the inner wall of the collection cover 65. The discharge pipe 66 is rotatably connected to the arc-shaped ring, and a sealing ring is provided at the connection between the discharge pipe 66 and the arc-shaped ring; The sealing performance at the connection between the discharge pipe 66 and the arc-shaped ring is enhanced through the sealing ring, preventing gas leakage at the connection between the discharge pipe 66 and the arc-shaped ring. Moreover, the central lines of the stirring blade 614 and the barrier cover 61 coincide, preventing the problem that the stirring blade 614 touches the barrier cover 61 during rotation.

[0024] As Figure 2 and Figure 3 shown, a drainage fan 7 is fixedly installed at the top end of the barrier cover 61. A discharge air pipe 8 is installed at the air outlet end of the drainage fan 7. An installation block 9 is fixedly installed on the outside of the barrier cover 61. Hydraulic rods 10 are symmetrically embedded and installed at the bottom end of the installation block 9. A base 11 is installed between the bottom ends of the two hydraulic rods 10, and the base 11 is fixedly installed inside the outer shell 1; it is convenient for the lifting of the barrier cover 61, changing the difficulty of lifting the barrier cover 61, and facilitating the flow of gas.

[0025] As Figure 3 and Figure 8 shown, a plurality of clamping and fixing structures 12 are equidistantly installed on the inner wall of the collection cover 65. The clamping and fixing structure 12 includes a threaded sleeve 1201 rotatably connected to the inner wall of the collection cover 65. A threaded rod 1202 is threadedly connected inside the threaded sleeve 1201. One end of the threaded rod 1202 is fixedly installed with a clamping block 1203, and a telescopic sleeve 1204 is embedded and installed at the bottom end of the clamping block 1203; Since the driving wheel 1206 drives the gear 1205 to rotate when it rotates, the gear 1205 drives the threaded sleeve 1201 to rotate when it rotates, and the threaded sleeve 1201 drives the threaded rod 1202 to rotate when it rotates. Since the threaded rod 1202 is limited by the clamping block 1203 and the telescopic sleeve 1204, the threaded rod 1202 cannot rotate at this time, and at this time, the threaded connection between the threaded sleeve 1201 and the threaded rod 1202 drives the threaded rod 1202 to displace, changing the difficulty of the position movement of the threaded rod 1202.

[0026] As Figure 3 and Figure 8 shown, a gear 1205 is clamped and installed on the outside of the threaded sleeve 1201. A driving wheel 1206 is meshed and connected to the outside of the gear 1205. A positioning rod 1207 is rotatably connected inside the driving wheel 1206. The positioning rod 1207 is fixedly installed on the inner wall of the collection cover 65. A magnetic strip one 1208 is fixedly installed on the outside of the positioning rod 1207. A magnetic strip two 1209 is fixedly installed on the inner wall of the driving wheel 1206. A barrier strip 1210 is fixedly installed on one end face of the driving wheel 1206, and the barrier strip 1210 is sleeved on the outside of the positioning rod 1207; When the connecting pipe 67 contacts the blocking strip 1210, the rotation of the connecting pipe 67 drives the blocking strip 1210 to swing at this time. When the blocking strip 1210 swings, it drives the second magnet strip 1209 to rotate, changing the distance between the second magnet strip 1209 and the first magnet strip 1208. At the same time, the blocking strip 1210 drives the driving wheel 1206 to rotate outside the positioning rod 1207, changing the rotation difficulty of the driving wheel 1206.

[0027] As Figure 3 and Figure 8 shown, the opposite surfaces of the first magnet strip 1208 and the second magnet strip 1209 have the same magnetic poles, and a positioning strip is fixedly installed outside the positioning rod 1207; Due to the positioning strip, the rotation position of the second magnet strip 1209 is limited, preventing excessive rotation of the second magnet strip 1209. And due to the principle that the first magnet strip 1208 and the second magnet strip 1209 have opposite magnetic poles, the second magnet strip 1209 moves, and then the second magnet strip 1209 drives the driving wheel 1206 to reset, changing the reset difficulty of the driving wheel 1206.

[0028] The present invention also provides a dust removal method for an automatic dust removal device, including the following steps: Step 1: Device positioning: Move the housing 1 to a preset working position.

[0029] Step 2: Equipment connection: Connect the suction hood 5 of the housing 1 to the object to be dusted.

[0030] Step 3: Start dust removal: Start the drainage fan 7 to filter the gas through the filter element 63 to separate the solid particles in the gas.

[0031] Step 4: Automatic cleaning: The gas flow drives the stirring blade 614 to rotate, and the stirring blade 614 cleans both sides of the filter element 63 through the brush 611; at the same time, drive a single clamping and fixing structure 12 to operate, and the remaining clamping and fixing structures 12 remain fixed.

[0032] Step 5: Dirt collection: The cleaned dirt falls into the collection cart 2 for centralized collection.

[0033] Working principle: During actual use of the device, the housing 1 is moved to a preset working position. Then, the corrugated pipe 4 is bent, and the suction hood 5 is made to enter the adsorption area. Next, the drainage fan 7 is started. At this time, the gas containing dirt from the outside enters the corrugated hood 13 along the suction hood 5, the corrugated pipe 4, and the diversion interface 3. Then, it enters the filtering structure 6 along the corrugated hood 13 and simultaneously enters the drainage fan 7 along the filter element 3 of the filtering structure 6. Then, it is discharged from the device along the exhaust pipe 8 of the drainage fan 7. When the gas is inside the barrier cover 61 of the filtering structure 6, the gas flows along the gap between the barrier cover 61 and the outer side of the filter element 63. As a result, the gas enters the middle position of the filter element 63 along the outer side of the filter element 63 and flows upward along the middle of the filter element 63. When the gas flows, it drives the stirring blade 614 to rotate. When the stirring blade 614 rotates, it drives the discharge pipe 66 to rotate. When the discharge pipe 66 rotates, it synchronously drives the connecting pipe 67 to rotate. When the connecting pipe 67 rotates, it drives the collection box 68 to rotate. When the collection box 68 rotates, it drives the concave plate 69 to rotate. Since the two concave plates 69 are symmetrically arranged, a rectangle is formed between the two concave plates 69. And under the action of the thickness of the filter element 63, the area between the two concave plates 69 is in a relatively sealed environment, thus reducing the interference of the outside gas on the objects inside the two concave plates 69. Since the two concave plates 69 drive the vertical plate 610 to move when they move, the vertical plate 610 drives the brush 611 to move when it moves. When the brush 611 moves, it alternately dredges the inside and outside of the filter element 63. The dirt after dredging naturally sinks due to the relatively enclosed space. The gas after sinking enters the collection box 68 and finally enters the collection cart 2 along the discharge pipe 66 and the connecting pipe 67 at the bottom of the collection box 68. By driving the stirring blade 614 and the brush 611 to perform dynamic cleaning through gas flow, combined with the relatively sealed collection environment, the cleaning efficiency and automation degree are significantly improved. At the same time, the dynamic cleaning and alternating dredging design effectively prevent the filter element 63 from being blocked, extend the service life of the filter element 63, and improve the dust removal efficiency and the stability of the equipment operation; And at this time, when the connecting pipe 67 rotates and contacts the blocking bar 1210, the rotation of the connecting pipe 67 drives the blocking bar 1210 to swing at this time. When the blocking bar 1210 swings, it drives the second magnet bar 1209 to rotate, so that the distance between the second magnet bar 1209 and the first magnet bar 1208 changes. At the same time, the blocking bar 1210 drives the driving wheel 1206 to rotate outside the positioning rod 1207. At the same time, when the driving wheel 1206 rotates, it drives the gear 1205 to rotate. When the gear 1205 rotates, it drives the threaded sleeve 1201 to rotate. When the threaded sleeve 1201 rotates, it drives the threaded rod 1202 to rotate. Since the threaded rod 1202 is limited by the clamping block 1203 and the telescopic sleeve 1204, the threaded rod 1202 cannot rotate at this time. And at this time, through the threaded connection between the threaded sleeve 1201 and the threaded rod 1202, the threaded rod 1202 is driven to displace. When the threaded rod 1202 moves, it drives the clamping block 1203 to enter the fitting groove inside the conical cover 62, so as to realize the suspended fixation of the conical cover 62. Through the cooperation of multiple groups of clamping and fixing structures 12, when one group of clamping and fixing structures 12 is in the open state, the conical cover 62 can still rotate fixedly, so that the drained gas can flow along the bottom end of the conical cover 62, and then the gas can enter evenly around the filter element 63, so that the filter element 63 can be used in all directions, increasing the effect during use, and effectively ensuring the operation of the synchronous cleaning structure inside and outside the filter element 63 in the filtering structure 6. This method optimizes the air flow path, improves the dust removal efficiency, and improves the utilization rate of the filter element 63, and prolongs its service life; Finally, disassemble the drainage fan 7 and the blocking cover 61, then start the hydraulic rod 10. The hydraulic rod 10 drives the blocking cover 61 to descend through the mounting block 9, and then the operator disassembles the filter element 63 installed inside the blocking cover 61, so as to achieve the purpose of facilitating the disassembly and replacement of the filter element 63.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
