Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology for manufactured sand, and more specifically, it relates to a dust removal device for manufactured sand production and processing. Background Technology
[0002] Manufactured sand is sand produced by sand making machines and their auxiliary equipment. Compared to natural sand, manufactured sand has more regular particle shapes, and its specifications and sizes can be adjusted through different processing techniques to better meet various engineering and daily needs. During the production and processing of manufactured sand, a large amount of fine dust often adheres to its surface. This dust generates significant amounts of airborne dust during transportation. To reduce pollution to the production environment, dust removal devices are needed. Existing dust removal devices for manufactured sand production typically use sieves to screen the sand, allowing dust and other impurities to pass through and separate from the sand. This method is relatively simple, leaving some dust adhering to the sand, thus reducing the dust removal effect. Furthermore, existing dust removal devices often place the manufactured sand directly onto the sieve at once, which easily leads to sand accumulation. This accumulation not only affects screening efficiency but may also result in poor dust removal, ultimately impacting the stability of the entire production process and product quality.

[0029] Please see Figures 1-6 A dust removal device for manufactured sand production and processing includes a dust collection box 1. A first screen plate 2 and a second screen plate 3 are movably arranged inside the dust collection box 1. A plurality of connecting rods 4 are fixed between the first screen plate 2 and the second screen plate 3. Two water spray pipes 5 are fixed inside the dust collection box 1. A plurality of nozzles 6 are provided on the water spray pipes 5. A pump body 7 is provided on one side of the dust collection box 1. The pump body 7 is connected to the two water spray pipes 5 through a pipe. A first filter plate 8 and two second filter plates 9 are fixed inside the dust collection box 1. A rotating shaft 10 is rotatably arranged inside the dust collection box 1. A scraper 11 is fixed on the rotating shaft 10. A gear 12 is fixedly arranged through the dust collection box 1 at one end of the rotating shaft 10. An electric push rod 13 is fixedly arranged on one side of the dust collection box 1. A rack 14 is fixedly arranged at the driving end of the electric push rod 13 and is slidably connected to the dust collection box 1 through a track. The rack 14 is meshed with the gear 12.
[0030] In this embodiment, when dust removal is required for manufactured sand, the manufactured sand is placed in the dust collection box 1 and then falls onto the first screen plate 2. The first screen plate 2 and the second screen plate 3 are inclined, so that the manufactured sand moves along the first screen plate 2 to the second screen plate 3 for sieving. Dust will be separated from the manufactured sand by passing through the first screen plate 2 and the second screen plate 3. A discharge port is provided on one side of the dust collection box 1, and the manufactured sand will be discharged from the discharge port along the second screen plate 3. During the process of the manufactured sand moving along the second screen plate 3, the pump body 7 is started. The pump body 7 delivers water in the dust collection box 1 to two water spray pipes 5, and then sprays it out from the nozzle 6. The manufactured sand is sprayed with water for cleaning. The water after cleaning is filtered through the first filter plate 8 and the second filter plate 9 and then enters the bottom of the dust collection box 1 for recycling. Both the first filter plate 8 and the second filter plate 9 are arc-shaped. When the electric push rod 13 is activated, the electric push rod 13 drives the rack 14 to move back and forth along the sliding connection with the dust collection box 1. Since the rack 14 is meshed with the gear 12, the gear 12 rotates back and forth. The gear 12 drives the rotating shaft 10 and the scraper 11 to rotate back and forth. The lower end of the scraper 11 contacts the first filter plate 8, thereby scraping and cleaning dust and other impurities onto the two second filter plates 9 for collection.
[0031] Please see Figures 1-6 As an embodiment of uniform feeding of manufactured sand: a feeding hopper 15 is fixedly provided at the upper end of the dust collection box 1, a rotating rod 16 is rotatably provided inside the feeding hopper 15, a plurality of feeding plates 17 are fixedly provided on the rotating rod 16, a first motor 18 is fixedly provided on one side of the dust collection box 1, the driving end of the first motor 18 extends into the dust collection box 1 and is fixedly connected to a convex column 19 rotatably connected to the dust collection box 1, a plurality of limiting shells 20 are fixedly provided inside the dust collection box 1, a lifting plate 21 is movably provided inside the limiting shell 20, a spring 22 is fixedly provided between the lower end of the lifting plate 21 and the limiting shell 20, a lifting rod 23 is fixedly provided at the upper end of the lifting plate 21, the upper end of the lifting rod 23 passes through the limiting shell 20 and is fixedly connected to the second screen plate 3, and a first synchronous belt drive structure 24 is provided between one end of the rotating rod 16 and the driving end of the first motor 18 passing through the feeding hopper 15.
[0032] Specifically, when it is necessary to feed manufactured sand, the manufactured sand is placed into the feed hopper 15, and the first motor 18 is started. The first motor 18 drives the rotating rod 16 to rotate through the first synchronous belt transmission structure 24. The rotating rod 16 drives multiple discharge plates 17 to rotate, so that the manufactured sand in the feed hopper 15 is fed at a uniform speed. The discharged manufactured sand enters the dust collection box 1 and falls onto the first screen plate 2. The first motor 18 drives the convex column 19 to rotate. When the protruding part of the convex column 19 rotates to contact the second screen plate 3, the rotation of the convex column 19 will push the second screen plate 3 upward. The second screen plate 3 moves upward, and the second screen plate 3 drives the lifting rod 23 to move. The lifting plate 21 moves, the spring 22 is compressed, and the second screen plate 3 moves the first screen plate 2 through multiple connecting rods 4. When the convex column 19 rotates to separate from the second screen plate 3, under the action of the spring 22 and gravity, the lifting plate 21 moves the lifting rod 23, the second screen plate 3, the connecting rods 4 and the first screen plate 2 downward. This is repeated, causing the first screen plate 2 and the second screen plate 3 to vibrate. Under the action of vibration, the first screen plate 2 disperses and screens the manufactured sand. At the same time, the manufactured sand falls along the first screen plate 2 onto the second screen plate 3 and continues to vibrate and screen. Finally, it is discharged from the discharge port. Dust will be separated from the manufactured sand through the first screen plate 2 and the second screen plate 3.
[0033] Please see Figures 1-6 As an embodiment for automatically cleaning impurities on the second filter plate 9: two drain shafts 25 are rotatably provided inside the dust collector 1, and spiral blades 26 are fixedly provided on the drain shafts 25. Two drain ports 27 that cooperate with the spiral blades 26 are provided on one side of the dust collector 1. A plug body 28 is provided on the drain port 27. A second motor 29 is fixedly provided on one side of the dust collector 1. A second synchronous belt drive structure 30 is respectively connected between one end of the two drain shafts 25 and the dust collector 1 and the second motor 29.
[0034] Specifically, when it is necessary to automatically clean the impurities on the second filter plate 9, the plug 28 is removed, the second motor 29 is started, the second motor 29 drives the two drain shafts 25 to rotate through the two second synchronous belt drive structures 30, the drain shafts 25 drive the spiral blades 26 to rotate, the outer side of the spiral blades 26 is in contact with the second filter plate 9, which can scrape and clean it while transporting the impurities and discharging them from the drain port 27.
[0035] In summary, when using the overall equipment:
[0036] When it is necessary to feed manufactured sand, the manufactured sand is placed into the feed hopper 15, and the first motor 18 is started. The first motor 18 drives the rotating rod 16 to rotate through the first synchronous belt transmission structure 24. The rotating rod 16 drives multiple discharge plates 17 to rotate, so that the manufactured sand in the feed hopper 15 is fed at a uniform speed. The discharged manufactured sand enters the dust collection box 1 and falls onto the first screen plate 2. The first motor 18 drives the convex column 19 to rotate. When the protruding part of the convex column 19 rotates to contact the second screen plate 3, the rotation of the convex column 19 will push the second screen plate 3 upward. The second screen plate 3 moves upward, and the second screen plate 3 drives the lifting rod 23 to move. The lifting rod 23 drives the lifting rod to move. As the lowering plate 21 moves, the spring 22 is compressed. Simultaneously, the second screen plate 3 drives the first screen plate 2 to move via multiple connecting rods 4. When the convex column 19 rotates to separate from the second screen plate 3, under the action of the spring 22 and gravity, the lifting plate 21 drives the lifting rod 23, the second screen plate 3, the connecting rods 4, and the first screen plate 2 to move downwards. This process is repeated, causing the first screen plate 2 and the second screen plate 3 to vibrate. Under the action of vibration, the first screen plate 2 disperses and sieves the manufactured sand. At the same time, the manufactured sand falls along the first screen plate 2 onto the second screen plate 3 and continues to vibrate and sieve. A discharge port is provided on one side of the dust collector 1. The manufactured sand is finally discharged from the discharge port, and the dust will be separated from the manufactured sand by passing through the first screen plate 2 and the second screen plate 3.
[0037] When dust removal is required for manufactured sand, the pump body 7 is started as the manufactured sand moves along the second screen plate 3. The pump body 7 delivers water from the dust collection box 1 to the two water spray pipes 5, and then sprays it from the nozzle 6 to clean the manufactured sand. The cleaned water is filtered through the first filter plate 8 and the second filter plate 9 and then enters the bottom of the dust collection box 1 for recycling. The first filter plate 8 and the second filter plate 9 are both arc-shaped. The electric push rod 13 is started, and the electric push rod 13 drives the rack 14 to move back and forth along the sliding connection with the dust collection box 1. Since the rack 14 is meshed with the gear 12, the gear 12 rotates back and forth, and the gear 12 drives the rotating shaft 10 and the scraper 11 to rotate back and forth. The lower end of the scraper 11 contacts the first filter plate 8, thereby scraping and cleaning dust and other impurities onto the two second filter plates 9 for collection.
[0038] Specifically, when it is necessary to automatically clean the impurities on the second filter plate 9, the plug 28 is removed, the second motor 29 is started, the second motor 29 drives the two drain shafts 25 to rotate through the two second synchronous belt drive structures 30, the drain shafts 25 drive the spiral blades 26 to rotate, the outer side of the spiral blades 26 is in contact with the second filter plate 9, which can scrape and clean it while transporting the impurities and discharging them from the drain port 27.
[0039] A controller is installed on the outside of the dust collector 1. All electrical equipment in the entire device is controlled by the controller. Since the equipment matched with the controller is common equipment, its control principle and wiring connection are existing, well-known, and mature technologies. Therefore, its electrical connection relationship and specific circuit structure will not be described in detail here. As the first synchronous belt drive structure 24 and the second synchronous belt drive structure 30 include a drive belt and a matching pulley, and since the first synchronous belt drive structure 24 and the second synchronous belt drive structure 30 are existing technologies, their specific structures and working principles will not be described in detail here.
[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
