Description

Technical Field

[0001] The invention relates to the technical field of belt cleaning, and in particular to a cleaning system on a transmission belt. Background Art

[0002] When the transmission belt is transporting materials, some materials will inevitably remain on its surface. During the material conveying process, the residual materials on the surface of the transmission belt need to be removed in time to keep the surface of the transmission belt clean.

[0003] At present, a scraper fitted with the belt is usually set at the end of the transmission belt or a roller brush fitted with the belt is set at the bottom of the transmission belt. As the transmission belt is conveyed, the scraper or the roller brush removes the residual material on the surface of the transmission belt.

[0004] When the transmission belt conveys a material with high viscosity and easy to solidify, after the material on the transmission belt is cleaned with an existing scraper or roller brush, the material is easy to adhere to the scraper or roller brush and then solidify, affecting the subsequent use of the scraper or roller brush, thereby reducing the cleaning effect, and the solidified material on the scraper or roller brush will scratch the belt surface. Summary of the invention

[0005] The object of the present invention is to provide a cleaning system for a transmission belt to solve the technical problem in the prior art that a scraper or roller brush structure is difficult to clean the sticky and easily solidified material remaining on the transmission belt.

[0013] Among them, the steering roller, the scrubbing box and the drying box are arranged in sequence along the running direction of the return surface of the transmission belt. The return surface of the transmission belt passes through the scraper, the scrubbing box and the drying box in sequence. The scraper scrapes off the material on the return surface of the transmission belt, and the roller brush brushes off the material remaining on the surface of the transmission belt.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a cleaning system for a transmission belt, comprising:

[0040] Transmission belt 1;

[0041] The steering roller 2 is arranged inside the transmission belt 1, and the return surface of the transmission belt 1 is wound around the outer surface of the steering roller 2, thereby changing the conveying direction of the transmission belt 1;

[0042] A scraper 3 is arranged at the bottom of the outer surface of the steering roller 2, and the transmission belt 1 is arranged between the steering roller 2 and the scraper 3, and the scraper 3 is in contact with the surface of the transmission belt 1, and is used to scrape the material on the surface of the transmission belt 1. A moving plate 4 is arranged on the outer side of the scraper 3, and the moving plate 4 moves back and forth along the length direction of the scraper 3, and is used to scrape the material on the surface of the scraper 3 and the connection between the scraper 3 and the transmission belt 1;

[0043] A scrubbing box 5 is used to scrub the surface of the transmission belt 1. A plurality of roller brushes 6 are installed at the bottom of the inner wall of the scrubbing box 5. The transmission belt 1 passes through the interior of the scrubbing box 5 after being turned by a plurality of transmission rollers.

[0044] A drying box 7, used to remove moisture from the outer surface of the transmission belt 1;

[0045] Among them, the steering roller 2, the scrubbing box 5 and the drying box 7 are arranged in sequence along the running direction of the return surface of the transmission belt 1. The return surface of the transmission belt 1 passes through the scraper 3, the scrubbing box 5 and the drying box 7 in sequence. The scraper 3 scrapes the material on the return surface of the transmission belt 1, and the roller brush 6 brushes off the residual material on the surface of the transmission belt 1. Then the drying box 7 dries the return surface of the transmission belt 1.

[0046] At present, most methods of cleaning the transmission belt 1 are to remove the residual material on the surface of the transmission belt 1 by using a scraper 3 or a roller brush 6. When the transmission belt 1 conveys a material with high viscosity and easy to solidify, after the material on the transmission belt 1 is removed by using the existing scraper 3 or roller brush 6, the material is easy to adhere to the scraper 3 or roller brush 6 and then solidify, affecting the subsequent use of the scraper 3 or roller brush 6, thereby reducing the cleaning effect, and the solidified material on the scraper 3 or roller brush 6 will scratch the belt surface. Therefore, it is necessary to develop a cleaning system for transmission belts that convey materials with high viscosity and easy to solidify.

[0047] In this embodiment, a movable plate 4 is provided on the outer side of the scraper 3 to remove the material scraped off the scraper 3 from the scraper 3, and the connection position of the scraper 3 and the belt is cleaned. A water spraying port is provided to spray water on the connection position of the scraper 3 and the belt to moisten it to prevent the material from solidifying. It is suitable for cleaning the residual viscous and easy-to-solidify material on the transmission belt 1, and the transmission belt 1 is further cleaned and dried in conjunction with the scrubbing box 5 and the drying box 7 to achieve continuous automatic cleaning.

[0048] In actual use, 1. The material with high viscosity and easy to solidify is continuously transported on the transmission belt 1, and the return surface of the transmission belt 1 is sequentially arranged between the steering roller 2 and the scraper 3 through multiple transmission rollers, the inside of the scrubbing box 5 and the inside of the drying box 7;

[0049] 2. Both sides of the return surface of the transmission belt 1 are respectively in contact with the steering roller 2 and the scraper 3;

[0050] 3. When the return surface of the conveyor belt 1 passes through the scraper 3, the scraper 3 scrapes off the material adhering to the return surface of the conveyor belt 1, and then the moving plate 4 moves back and forth along the length direction of the scraper 3 to scrape off the material on the surface of the scraper 3 and the connection between the scraper 3 and the conveyor belt 1, so as to prevent the material scraped off by the scraper 3 from solidifying on the surface of the scraper 3;

[0051] 4. The conveyor belt 1 from which most of the adhered material has been scraped off by the scraper 3 passes through the scrubbing box 5, and the roller brush 6 scrubs the surface of the conveyor belt 1 again to scrub off a small amount of material remaining on the surface of the conveyor belt 1. Since the conveyor belt 1 is soaked in the water in the scrubbing box 5 for scrubbing, the material on the conveyor belt 1 is more easily scrubbed off and is not easy to solidify;

[0052] 5. The cleaned transmission belt 1 passes through a drying box 7 to dry the surface moisture, completing the cleaning process.

[0053] As a preferred embodiment of this implementation, Figure 2 As shown, the vertical cross-section shape of the scraper 3 is set to be triangular, the side of the scraper 3 close to the steering roller 2 is set to be a concave arc, and the side of the scraper 3 close to the steering roller 2 is in contact with the outer surface of the steering roller 2, and the side of the scraper 3 away from the steering roller 2 is set to be a convex arc;

[0054] The connection between the concave side and the convex side of the scraper 3 is set as a scraping line 8, and the scraping line 8 is set along the length direction of the steering roller 2. When the transmission belt 1 passes through the scraping line 8 during transportation, the scraper 3 scrapes off the material on the transmission belt 1.

[0055] In the present invention, the scraper 3 is designed so that the scraper 3 fits the surface of the steering roller 2 and the transmission belt 1 , and when the transmission belt 1 passes through the scraping line 8 , the scraper 3 scrapes off the material on the transmission belt 1 .

[0056] After the scraper 3 scrapes the material on the transmission belt 1, the material will move downward along the outside of the scraper 3, but the material will always remain on the outside of the scraper 3. For materials with high viscosity and easy to solidify, the material will solidify on the outside of the scraper 3 and at the scraping line 8. When the transmission belt 1 passes through the scraper 3, the solidified material will damage the transmission belt 1.

[0057] In order to solve the above problems, the present application provides a movable plate 4 on the outer side of the scraper 3, the movable plate 4 is arranged on the side of the scraper 3 away from the steering roller 2, and the side of the movable plate 4 close to the scraper 3 is arranged to be a concave arc, so that the side of the movable plate 4 close to the scraper 3 is in contact with the scraper 3, and the top of the side of the movable plate 4 close to the scraper 3 is in contact with the scraping line 8 and the transmission belt 1 respectively;

[0058] When the moving plate 4 moves back and forth along the length direction of the scraper 3 , the moving plate 4 scrapes off the material on the surface of the moving plate 4 and removes the material at the connection between the scraper 3 and the transmission belt 1 .

[0059] When the movable plate 4 moves back and forth along the length direction of the scraper 3, the movable plate 4 scrapes off the material on the surface of the movable plate 4 and removes the material at the connection between the scraper 3 and the transmission belt 1. The moving movable plate 4 can timely clean the material scraped off by the scraper 3 from the scraper 3 to prevent the material from adhering to the scraper 3 and solidifying.

[0060] Due to the high viscosity and easy solidification of the material itself, even if the material at the scraping line 8 is scraped off by the moving plate 4, a small part of the material will still solidify. In order to solve this problem, Figure 3 As shown, water spray pipes 9 are provided on both sides of the top of the movable plate 4, the water spray pipes 9 are at the same height as the scraping line 8, and the water spray pipes 9 are arranged toward the scraping line 8;

[0061] When the moving plate 4 moves back and forth along the length direction of the scraper 3 , the water spraying pipe 9 sprays industrial water toward the scraping line 8 to wet the material body remaining at the scraping line 8 .

[0062] The industrial water sprayed from the water spray pipe 9 is directly sprayed to the scraping line 8 position to wet and dilute the material at the scraping line 8 position, effectively preventing the material near the scraping line 8 from solidifying and accelerating the downward flow of the material on the scraper 3.

[0063] In order to prevent the moving plate 4 from affecting the scraping effect of the scraper 3, the length of the scraper 3 is greater than the length of the steering roller 2, and the length of the moving plate 4 is less than one tenth of the overall length of the scraper 3. The moving plate 4 can effectively clean the material on the scraper 3 without affecting the scraping effect of the scraper 3.

[0064] The specific moving structure of the moving plate 4 is described in detail below. A threaded rod 10 is provided on one side of the scraper 3 and is arranged parallel to the steering roller 2. The threaded rod 10 passes through the moving plate 4, and the moving plate 4 is threadedly connected to the threaded rod 10. A motor 11 is connected to one end of the threaded rod 10. A sliding rod 12 is provided on one side of the threaded rod 10. The sliding rod 12 passes through the moving plate 4 and is slidably connected to the moving plate 4.

[0065] The output shaft of the motor 11 rotates to drive the threaded rod 10 to rotate, thereby driving the movable plate 4 to move along the slide rod 12 , so that the movable plate 4 moves along the length direction of the steering roller 2 in contact with the scraper 3 .

[0066] Through the cooperation between the threaded rod 10 and the sliding rod 12 , the movable plate 4 can move in close contact with the scraper 3 .

[0067] The existing roller brush 6 has a brush fixed on the outer surface of the rotating roller, and the rotating roller is arranged along the width direction of the transmission belt 1. The rotation direction of the rotating roller is the same as or opposite to the conveying direction of the transmission belt 1. Since the brushing direction of the brush is on the same horizontal line as the moving direction of the transmission belt 1, there will be residual material on the transmission belt 1 after being brushed by the existing roller brush 6, and the cleaning is not thorough.

[0068] The existing roller brush 6 directly brushes the transmission belt 1, and the transmission belt 1 does not contact the cleaning water. For materials with high viscosity and easy to solidify, it is not easy to brush them clean, and the materials are easy to adhere to the brush, causing the materials to solidify on the brush.

[0069] In order to solve the above problems, further, Figure 1 As shown, the roller brushes 6 are arranged in at least two rows, each row of the roller brushes 6 is arranged along the width direction of the transmission belt 1, and the two rows of the roller brushes 6 are staggered, and the distance between two adjacent roller brushes 6 is less than the diameter of the roller brush 6;

[0070] The roller brush 6 includes a rotating disk 13 and bristles 14 fixed on the rotating disk 13. The bottom of the rotating disk 13 is connected to a rotating shaft 15, and the rotating shaft 15 is connected to a driver.

[0071] The bristles 14 are in contact with the transmission belt 1 . When driven by a driver, the rotating shaft 15 rotates to drive the rotating disk 13 to rotate, thereby driving the bristles 14 to make a circular motion to brush the transmission belt 1 .

[0072] The roller brush 6 in the present application has a different rotation direction from that in the prior art. The roller brush 6 in the present application rotates horizontally, which is different from the moving direction of the transmission belt 1. It can better brush the transmission belt 1 at multiple angles and improve the overall brushing effect. At the same time, clean water is injected into the brushing box 5 so that the transmission belt 1 and the roller brush 6 are immersed in water, which can moisten the material body, facilitate brushing, and prevent the material body from solidifying on the surface of the roller brush 6.

[0073] After the transmission belt 1 is scrubbed in the scrubbing box 5, a large amount of water will adhere to its surface. In order to facilitate the subsequent rapid drying of the transmission belt 1 by the drying box 7, at least two scrapers 16 are provided between the scrubbing box 5 and the drying box 7. The two scrapers 16 are respectively arranged on both sides of the transmission belt 1, and the transmission belt 1 located at the scraper 16 part is in a tilted downward state. When the transmission belt 1 in transport passes through the scraper 16, the cleaning water remaining on its surface is scraped off and flows into the scrubbing box 5;

[0074] At least two wiping blocks 17 are provided on the side of the wiper 16 away from the scrubbing box 5 . The two wiping blocks 17 are respectively arranged on both sides of the transmission belt 1 . When the transmission belt 1 passes through the wiping blocks 17 after being wiped, the water remaining on its surface is absorbed by the wiping blocks 17 .

[0075] After being scrubbed, the transmission belt 1 first passes through the wiper 16 and then passes through the drying block 17. The wiper 16 scrapes off most of the water on both sides of the transmission belt 1, and the drying block 17 absorbs the remaining water drops on both sides of the transmission belt 1.

[0076] In order to keep the transmission belt 1 dry, at least two hot air pipes 18 are provided between the drying block 17 and the drying box 7. The two hot air pipes 18 are respectively arranged on both sides of the transmission belt 1. The two hot air pipes 18 spray hot air toward the transmission belt 1 in transport, thereby drying the surface of the transmission belt 1.

[0077] An exhaust pipe 19 is provided on the top of the drying box 7, and the hot air pipe 18 is connected to the exhaust pipe 19 through a connecting pipe. The exhaust gas discharged from the drying box 7 is sprayed onto the surface of the transmission belt 1 through the hot air pipe 18 to pre-dry the transmission belt 1.

[0078] Before the transmission belt 1 is dried by the drying box 7, the hot air pipe 18 pre-dries the transmission belt 1, and the exhaust gas discharged by the drying box 7 pre-dries the transmission belt 1, thereby saving resources and realizing the reuse of the exhaust gas.

[0079] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
