Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Please see Figures 1-3 This utility model provides a technical solution: a dust removal and impurity removal device before rapeseed oil pressing, including a support frame 1 and a screening frame 5. The upper end of the support frame 1 is provided with mounting seats 2, each mounted with a rubber spring 3 installed longitudinally within each mounting seat 2. Each rubber spring 3 is also mounted with a return spring 4 installed longitudinally within each rubber spring 3. The screening frame 5 is located above the support frame 1. A dust removal screen 9 is horizontally installed at the lower end of the screening frame 5, and an impurity removal screen 11 is horizontally installed at the upper end of the screening frame 5. Vertical supports 13 are longitudinally welded to the left and right sides of the upper end of the screening frame 5. Multiple mounting cylinders 14 are bolted through the two vertical supports 13, and each mounting cylinder 14 contains a fan 15. The front end of the screening frame 5 is bolted... A motor frame 6 is installed, and a vibrating motor 7 is longitudinally fixed inside the motor frame 6 by bolts. A swing plate 8 is installed on the movable end of the vibrating motor 7. A bending plate 16 is fixed to the left end of the screening frame 5 by bolts. An electric push rod 17 is horizontally installed on the right end of the bending plate 16 by flange and bolts. A guide push plate 18 is installed on the movable end of the electric push rod 17 by flange and bolts. Two hanging plates 19 are longitudinally welded inside the guide push plate 18. A roller 20 is movably installed between the two hanging plates 19. A cylindrical soft magnet sheet 21 is glued to the outside of the roller 20. This design solves the problem that most existing screening and air separation equipment are set up separately, which is inconvenient for multiple screening of rapeseed oil raw materials and affects the screening efficiency of rapeseed oil raw materials.
[0019] As the first embodiment of this utility model: flanges and bolts are provided around the lower end of the screening frame 5, and the upper ends of multiple rubber springs 3 are respectively connected to multiple flanges. The screening frame 5 can be elastically supported by the added multiple rubber springs 3 and multiple return springs 4.
[0020] The screen openings of the impurity removal screen 11 are larger than the diameter of the rapeseed oil raw material, and the diameter of the rapeseed oil raw material is larger than the diameter of the dust removal screen 9. By adding the impurity removal screen 11, which has a larger diameter than the rapeseed oil raw material, and the rapeseed oil raw material has a larger diameter than the dust removal screen 9, the impurity removal screen 11 can easily intercept larger impurities, while the dust removal screen 9 can intercept the rapeseed oil raw material and facilitate the discharge of fine dust.
[0021] A first strip-shaped baffle 10 is fixed to the lower right side of the screening frame 5 by multiple bolts, and a second strip-shaped baffle 12 is fixed to the upper left side of the screening frame 5 by multiple bolts. The first strip-shaped baffle 10 can be disassembled to facilitate opening the right side of the dust removal screen 9, and the second strip-shaped baffle 12 can be disassembled to facilitate opening the left side of the impurity removal screen 11. Strip-shaped slide rails are provided at both the front and rear ends inside the screening frame 5. A guide push plate 18 slides along two of these slide rails, improving the smoothness of its movement. A cylindrical soft magnet 21 is horizontally positioned above the dust removal screen 9, magnetically attracting metal particles that fall onto the screen.
[0022] As a second embodiment of this utility model: Rapeseed oil raw material is added to the impurity removal screen 11. The vibration motor 7 is started, driving the oscillating plate 8 to rotate. Due to the eccentric force, the motor frame 6 drives the screening frame 5 to vibrate, causing the impurity removal screen 11 and the dust removal screen 9 to vibrate accordingly. During this process, multiple return springs 4 and multiple rubber springs 3 provide auxiliary support. The screen holes of the impurity removal screen 11 are larger than the diameter of the rapeseed oil raw material, and the rapeseed oil raw material is larger than the diameter of the screen holes of the dust removal screen 9. The impurity removal screen 11 will intercept larger impurities, thus reducing the amount of rapeseed oil... The raw materials fall onto the dust removal screen 9, which intercepts the rapeseed oil raw materials, facilitating the discharge of fine dust. At the same time, two fans 15 are activated, which blow air onto the impurity removal screen 11, thus facilitating the discharge of light impurities. After completion, the vibration motor 7 is turned off, and the electric push rod 17 is activated. The movable end of the electric push rod 17 drives the guide push plate 18, the hanging plate 19, the roller 20, and the cylindrical soft magnetic sheet 21 to move to the right. During this process, the cylindrical soft magnetic sheet 21 comes into contact with the rapeseed oil raw materials and magnetically adsorbs the metal particles in them.
