[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1 Please see Figures 1-3The present invention provides a technical solution: a filter cloth spray dust removal device, including a cleaning box 1, which is provided with an inlet 11 and an outlet 12, which are correspondingly arranged; a drain pipe 13 is connected to the cleaning box 1, and a control valve (not shown in the figure) is provided on the drain pipe 13; a pre-scraping mechanism 2 is provided on the cleaning box 1, and there are two pre-scraping mechanisms 2, which are centrally symmetrically arranged; the filter cloth to be dusted passes through the inlet 11 and the outlet 12, and at the same time, the filter cloth also passes through the two pre-scraping mechanisms 2, which are used to scrape the upper and lower surfaces of the filter cloth respectively; in addition, the two ends of the filter cloth are respectively used to connect an external unwinding device and a winding device, the unwinding device is used to unwind the filter cloth, and the winding device is used to wind the filter cloth; a drying device can be provided between the winding device and the cleaning box 1.

[0031] The pre-scraping mechanism 2 includes a rotating shaft 21, the two ends of which are movably mounted on the cleaning tank 1 via bearings; two support discs 22 are sleeved on the outside of the rotating shaft 21, and the support discs 22 are fixedly connected to the rotating shaft 21; a spiral scraping rod 23 is arranged between the two support discs 22, the spiral scraping rod 23 is sleeved on the outside of the rotating shaft 21, and the spiral scraping rod 23 is coaxial with the rotating shaft 21; one end of the rotating shaft 21 is connected to a second rotating component 24, which is used to drive the rotating shaft 21 to rotate.

[0032] The second rotating assembly 24 includes a second geared motor 241, which is mounted on the outer wall of the cleaning tank 1. The output shaft of the second geared motor 241 is connected to the rotating shaft 21, and the output shaft of the second geared motor 241 is coaxial with the rotating shaft 21.

[0033] The outer wall of the spiral scraper 23 is provided with a groove 231. The groove 231 extends along the surface of the spiral scraper 23 and forms a spiral shape. The edge of the groove 231 is chamfered. The spiral scraper 23 can be made of plastic.

[0034] A limiting roller 25 is provided on one side of the spiral scraper 23, and the two ends of the limiting roller 25 are fixedly mounted on the cleaning box 1. Since there are two pre-scraping mechanisms 2, namely, two rotating shafts 21, two spiral scraper 23 and two limiting rollers 25, the two spiral scraper 23 are located on the upper and lower sides of the filter cloth respectively. The two spiral scraper 23, the two rotating shafts 21 and the two limiting rollers 25 are all centrally symmetrically arranged, and the filter cloth is clamped between the spiral scraper 23 and the limiting roller 25 on one side of the spiral scraper 23.

[0035] A spray assembly 3 is provided between the two spiral scraper bars 23. The spray assembly 3 is used to connect to an external pressure water source so as to spray water onto the upper and lower surfaces of the spiral scraper bars 23. Specifically, a water supply system composed of a water tank, water pump, etc. can be used to supply water to the spray assembly 3. This is existing technology and will not be described in detail here.

[0036] When cleaning the filter cloth, two second reduction motors 241 drive two rotating shafts 21 to rotate, and the two rotating shafts 21 drive the corresponding support disks 22 to rotate, thereby driving the two spiral scraping rods 23 to rotate. Since the spiral scraping rods 23 have a spiral structure and are provided with grooves 231, it is convenient for the two spiral scraping rods 23 to scrape the impurities on the upper and lower surfaces of the filter cloth. At the same time, during the rotation and scraping process, the spiral scraping rods 23 have a pushing effect on the impurities along the axis of the rotating shafts 21. Combined with the spraying effect of the spray assembly 3, it is easy to improve the dust removal effect of the spray on the filter cloth.

[0037] Example 2 See again Figure 3 Based on Embodiment 1, this embodiment also includes an upper surface scraping mechanism 4 and a lower surface scraping mechanism 5. The upper surface scraping mechanism 4 and the lower surface scraping mechanism 5 are located between the pre-scraping mechanism 2 and the discharge port 12, and are arranged sequentially along the filter cloth conveying direction.

[0038] Please see Figures 3-6 The upper surface scraping mechanism 4 includes two support rollers 41, which are arranged in parallel and one end of each support roller 41 is fixedly mounted on the cleaning tank 1. A first elastic spiral rod 42 and a guide ring 44 are coaxially arranged outside the support rollers 41. The guide ring 44 is located near the end of the support roller 41 that is fixedly connected to the cleaning tank 1 and is fixedly mounted on the cleaning tank 1. A guide ball 45 is provided at one end of the first elastic spiral rod 42, and a first rotating component 43 is connected to the other end of the first elastic spiral rod 42. The first rotating component 43 is used to drive the first elastic spiral rod 42 to rotate. A plurality of first brushes 46 are provided at the bottom of the support roller 41. The first brushes 46 are flexible brushes. The plurality of first brushes 46 are evenly arranged along the axial direction of the support roller 41 and are located between adjacent turns of the first elastic spiral rod 42.

[0039] The lower surface scraping mechanism 5 also includes two support rollers 41. The two support rollers 41 of the lower surface scraping mechanism 5 are arranged in parallel, and the two support rollers 41 corresponding to the lower surface scraping mechanism 5 are located obliquely below the support rollers 41 corresponding to the upper surface scraping mechanism 4. The support rollers 41 of the lower surface scraping mechanism 5 are coaxially provided with a second elastic spiral rod 51 and a guide ring 44. The two ends of the second elastic spiral rod 51 are also connected to guide balls 45 and a first rotating component 43, respectively. The top of the support rollers 41 of the lower surface scraping mechanism 5 is provided with a plurality of second brushes 52. The plurality of second brushes 52 are evenly arranged along the length direction of the support rollers 41, and the plurality of second brushes 52 are respectively located between each adjacent turn of the second elastic spiral rod 51.

[0040] Each of the first rotating components 43 includes a first geared motor 431. The first geared motor 431 is mounted on the outer wall of the cleaning tank 1. The output shaft of the first geared motor 431 penetrates the cleaning tank 1 and is fixedly connected to a rotating disk 432. The rotating disk 432 is coaxial with the output shaft of the first geared motor 431.

[0041] Because it has two first elastic helical rods 42 and two second elastic helical rods 51, it has four first rotating components 43, thus having four rotating disks 432. The first elastic helical rods 42 and the second elastic helical rods 51 are respectively connected to the corresponding rotating disks 432, and the first elastic helical rods 42 are coaxial with the corresponding rotating disks 432, while the second elastic helical rods 51 are coaxial with the corresponding rotating disks 432. The rotating disks 432 are driven to rotate by the first reduction motor 431, thereby driving the first elastic helical rods 42 and the second elastic helical rods 51 to rotate, which in turn drives the guide ball 45 to rotate.

[0042] Please see Figures 4-8 The guide ring 44 is provided with a first arc-shaped groove 441 and a second arc-shaped groove 442, and an arc transition portion 443 is provided between the first arc-shaped groove 441 and the second arc-shaped groove 442; in addition, the depth of the first arc-shaped groove 441 is less than the depth of the second arc-shaped groove 442; since the first elastic screw rod 42 and the second elastic screw rod 51 are elastic, the first elastic screw rod 42 and the second elastic screw rod 51 respectively drive the corresponding guide ball 45 to always be in contact with the guide ring 44, and in the initial state (i.e., as shown) Figure 4 and Figure 6As shown in the diagram, the guide ball 45 connected to the first elastic spiral rod 42 and the second elastic spiral rod 51 is located in the second arc-shaped groove 442. That is, during the rotation of the guide ball 45, through the action of the arc transition part 443, the guide ball 45 can move from the first arc-shaped groove 441 to the second arc-shaped groove 442, and the guide ball 45 can also move from the second arc-shaped groove 442 to the first arc-shaped groove 441. Since the depth of the first arc-shaped groove 441 is less than the depth of the second arc-shaped groove 442, when the guide ball 45 moves from the second arc-shaped groove 442 to the first arc-shaped groove 441, the first elastic spiral rod 42 and the second elastic spiral rod 51 are compressed. On the one hand, this improves the scraping and cleaning effect of impurities, and on the other hand, it causes the first elastic spiral rod 42 and the second elastic spiral rod 51 to squeeze the first brush 46 and the second brush 52 respectively.

[0043] Please see Figures 2-8 The filter cloth is threaded between the first elastic spiral rod 42 and the second elastic spiral rod 51. The first elastic spiral rod 42 and the first brush 46 are used to contact the upper surface of the filter cloth, while the second elastic spiral rod 51 and the second brush 52 are used to contact the lower surface of the filter cloth. In addition, the first elastic spiral rod 42 and the second elastic spiral rod 51 have a circular cross-section, and both the first elastic spiral rod 42 and the second elastic spiral rod 51 are made of spring steel, which gives the first elastic spiral rod 42 and the second elastic spiral rod 51 good strength, toughness and elasticity.

[0044] In addition, in this embodiment, two sets of guide roller groups 6 are provided in the cleaning tank 1. The two sets of guide roller groups 6 are close to the feed inlet 11 and the discharge outlet 12 respectively. The guide roller group 6 is composed of two guide rollers 61 that are symmetrically arranged at the top and bottom. The two ends of the guide rollers 61 are movably connected to the cleaning tank 1 through bearings. By passing the filter cloth between the two guide rollers 61 included in the guide roller group 6, the stability of the filter cloth movement is improved. In addition, the filter cloth can be prevented from contacting the inner wall of the feed inlet 11 and the discharge outlet 12.

[0045] A spray assembly 3 is provided between each pair of adjacent support rollers 41, and a spray assembly 3 is also provided between the support roller 41 closest to the discharge port 12 and the discharge port 12. That is, this embodiment adds four spray assemblies 3 based on the first embodiment.

[0046] In this embodiment, all spraying components 3 spray water onto the upper and lower surfaces of the filter cloth. The filter cloth is first cleaned by the pre-scraping mechanism 2, and simultaneously, the first reduction motor 431 drives the rotating disk 432 to rotate, thereby rotating the two first elastic spiral rods 42 and the second elastic spiral rod 51. The second elastic spiral rod 51, the first brush 46, and the second brush 52 scrape and clean the upper and lower surfaces of the filter cloth. At the same time, the second elastic spiral rod 51 and the second elastic spiral rod 52 drive the corresponding guide balls 45 to move. When the guide ball 45 moves from the second arc-shaped groove 442 to the first arc-shaped groove 441, the first elastic spiral rod 42 and the second elastic spiral rod 51 are elastically compressed. When the guide ball 45 moves from the first arc-shaped groove 441 to the second arc-shaped groove 442, the first elastic spiral rod 42 and the second elastic spiral rod 51 are elastically compressed. The extension and reset of the elastic spiral rod 51, during the elastic compression of the first elastic spiral rod 42 and the second elastic spiral rod 51, helps to improve the scraping effect of the first elastic spiral rod 42 and the second elastic spiral rod 51 on the filter cloth surface. At the same time, the first elastic spiral rod 42 and the second elastic spiral rod 51 respectively disturb the first brush 46 and the second brush 52, improving the scraping effect of the first brush 46 and the second brush 52 on the filter cloth surface. In addition, during the rotation of the first elastic spiral rod 42 and the second elastic spiral rod 51, they cyclically compress and reset, and the first elastic spiral rod 42 and the second elastic spiral rod 51 themselves adopt a spiral structure, which effectively enhances the scraping and removal effect on the filter cloth surface. With the help of multiple spray components 3 spraying water on the upper and lower surfaces of the filter cloth, it is easy to thoroughly clean the filter cloth surface impurities. The cleaning wastewater is collected in the cleaning tank 1 and discharged through the drain pipe 13.

[0047] Example 3 Please see Figure 3 , Figure 9 Based on Embodiment 2, the spray assembly 3 includes a first liquid guide pipe 33, an upper spray pipe 31, and a lower spray pipe 32. The upper spray pipe 31 and the lower spray pipe 32 are correspondingly arranged, and a second liquid guide pipe 34 is connected between the upper spray pipe 31, the lower spray pipe 32, and the first liquid guide pipe 33. An inlet pipe 35 is connected to the first liquid guide pipe 33. The inlet pipe 35 passes through the bottom of the cleaning tank 1 and is sealed to the cleaning tank 1. The inlet pipe 35 is used to connect to an external pressure water source. The first liquid guide pipe 33 is fixedly arranged on the inner wall of the cleaning tank 1, and the ends of the upper spray pipe 31 and the lower spray pipe 32 can be connected to the inner wall of the cleaning tank 1 through brackets.

[0048] Example 4 Please see Figures 1-10Based on Embodiment 3, this embodiment has multiple sealing covers 7 on the top of the cleaning tank 1, as shown in the figure. There are four sealing covers 7, which cover the top of the cleaning tank 1 and can all be removed. By removing the sealing covers 7, it is convenient to pre-install the filter cloth, thereby facilitating the subsequent cleaning of the filter cloth.
