Technical Field

[0001] This utility model relates to the technical field of material separation equipment, specifically to material impurity separation equipment. Background Technology

[0002] Material impurity separation involves removing unusable impurities from materials to extract usable materials. Examples include sawdust separation and slag separation. Different separation methods are required depending on the material to be separated: commonly, these include air separation, water separation, and vibratory screening. Vibratory screening is the most frequently used method.

[0003] Chinese patent CN208824960U discloses an anti-clogging vibrating screen, including a base, a vibration source, a housing, and a spring. The housing contains multiple screens distributed from top to bottom, each screen having a through hole at its center. Several scrapers extending towards the screen surface are arranged on the outer surface of the rotating rod. The rotating rod is connected to a drive motor. A ring-shaped material-blocking step extending upwards is provided on the screen corresponding to the through hole. This invention can turn over the material on the screen surface while the screen vibrates, causing the material to tumble quickly and preventing the screen surface from being blocked by large particles for extended periods.

[0004] This invention improves the anti-clogging effect by turning the material over, reducing the prolonged obstruction of large particles. However, when large particles vibrate to the edge of the screen, they are not easily removed, which affects the screening effect. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a material impurity separation device, including a separator 1, a vibrating feeder 2, a belt conveyor 3 and a suction device 4. One end of the vibrating feeder 2 is located on one side of the separator 1, and the other end of the vibrating feeder 2 is located on one side of the belt conveyor 3. A suction pipe 5 is provided on one side of the suction device 4, and the suction pipe 5 is located above the belt conveyor 3. The separator 1 includes a base 13, and a separation chamber 6 and a connecting structure 18 for the separation chamber 6 to sway are provided above the base 13. A driving structure 19 for driving the separation chamber 6 to sway is provided inside the base 13. A screen 9 and an anti-clogging structure 20 for the screen 9 are installed inside the separation chamber 6.

[0025] By setting up a separator 1, the material is stratified and screened, and then discharged through the discharge port 10 above the vibrating feeder 2. Through vibration, the material enters the belt conveyor, where the suction feeder 4 further separates materials of different weights, improving the separation effect. The anti-clogging structure 20 allows large pieces of material on the screen 9 to be cleaned up in a timely manner.

[0026] The anti-clogging structure 20 includes a screen base 2001 and a scraper 2002. The screen base 2001 is arranged in a ring shape. A rotating disk 2003 is installed on the upper surface of the screen base 2001. One end of the scraper 2002 is fixed above the rotating disk 2003. A drive for rotating the rotating disk 2003 is provided on one side of the screen base 2001.

[0027] The scraper 2002 is fixedly connected to the rotating disk 2003. When the rotating disk 2003 rotates, as... Figure 3 As shown, the scraper 2002 scrapes above the screen 9 to scrape large pieces of material.

[0028] The rotation drive includes a rotation motor 2004. A platform 2005 for mounting the rotation motor 2004 is provided on one side of the screen base 2001. The output end of the rotation motor 2004 passes through the platform 2005 through a rotating shaft and is fixed with a drive gear 2006. A driven gear 2007 is provided at the bottom of the rotating disk 2003. The driven gear 2007 meshes with the drive gear 2006.

[0029] The scraper 2002 is arc-shaped, and the upper surface of the screen base 2001 is provided with an annular groove 2008 for fixing the screen 9. The sorting bin 6 is provided with a discharge port 10 on one side.

[0030] The drive structure 19 includes a drive motor 1901 and an eccentric wheel 1902. Both the output end of the drive motor 1901 and the shaft on one side of the eccentric wheel 1902 are equipped with synchronous pulleys 1903. A synchronous belt 1904 is provided between the two synchronous pulleys 1903. The bottom of the sorting bin 6 is fixedly connected to the shaft on the other side of the eccentric wheel 1902.

[0031] After the drive motor 1901 is started, the eccentric wheel 1902 is driven to rotate through the synchronous belt 1904, causing the sorting bin 6 to rotate eccentrically, mimicking the manual shaking of the screen 9.

[0032] The connecting structure 18 includes an upper support leg 1801, a lower support leg 1802, and a spring 1803. The upper support leg 1801 is fixedly connected to the bottom of the sorting bin 6, the lower support leg 1802 is fixedly connected to the base 13, the top end of the spring 1803 is sleeved on the outside of the upper support leg 1801 and fixedly connected to the upper support leg 1801, and the bottom end of the spring 1803 is sleeved on the outside of the lower support leg 1802 and fixedly connected to the lower support leg 1802.

[0033] The sorting chamber 6 has a ring-shaped cross-section, and rubber balls 12 are placed on the upper surface of the screen 9. The top of the sorting chamber 6 has a feed inlet 8. The rubber balls 12 are used to assist the screen 9 in preventing clogging. This is a common anti-clogging method for vibrating screens in the prior art, and will not be described in detail here.

[0034] The feeder 4 includes a support frame 15, a feed chamber 401 is installed on the top of the support frame 15, a spiral feed channel 16 is provided in the feed chamber 401, a feed port 14 for connecting to the feed pipe 5 is provided at the upper part of the feed channel 16, and a fan 17 is installed on the top of the feed chamber 401.

[0035] In use, the material is placed into the sorting bin 6 through the feed inlet 8. After the drive motor 1901 starts running, it drives the eccentric wheel 1902 to rotate, causing the sorting bin 6 connected to the eccentric wheel 1902 to shake. This design mimics the shaking of an artificial arm, allowing the material to be screened by the screen 9 within the sorting bin 6. The sorting bin 6 has three layers, with a screen 9 installed at the bottom of each layer. When installing the screen 9, it is first fixed inside the screen holder 2001, and then the screen holder 2001 is fixed to the inner wall of the sorting bin 6. Figure 2 As shown, by setting different mesh sizes for the screens 9 in different layers, materials can be efficiently separated according to different sizes. The separated materials flow out through the discharge ports 10 in different layers and fall into the hopper of the vibrating feeder 2 below. Under the action of the vibrating feeder 2, the materials are evenly pushed forward and fall onto the belt conveyor 3, which then sends them to the suction device 4. By configuring fans 17 with different air volumes, materials and impurities of different sizes are effectively and quickly separated, thereby refining clean finished materials, ensuring separation effect and high working efficiency.

[0036] When it is necessary to clean large pieces of material from the edge of screen 9, start the rotating motor 2004, which causes the drive gear 2006 to drive the driven gear 2007 to rotate, thereby causing the rotating disk 2003 to drive the scraper 2002 to rotate, scraping the large pieces of material from the edge of screen 9 to the discharge port 10 for manual cleaning. This method facilitates the timely removal of large pieces of material and can improve the screening effect of screen 9.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
