Description

Technical Field

[0001] The present invention relates to the technical field of coated sand regeneration, and particularly to a multiple refinement and crushing device for coated sand regeneration. Background Art

[0002] During the crushing and refinement process of coated sand, in addition to conventional particle size control and equipment maintenance, there are also some potential problems that are easily overlooked but may seriously affect the quality of recycled sand and production efficiency, such as the agglomeration effect caused by electrostatic adsorption. When the coated sand is mechanically crushed, high-speed friction and collision between sand grains and between sand grains and the equipment will generate static charges, which will cause fine sand grains (especially fine powder) to agglomerate due to electrostatic action, or adhere to the inner wall of the equipment and the screen, resulting in screen hole blockage, affecting the screening efficiency, and at the same time leading to uneven particle size distribution.

[0003] The existing crushing devices for coated sand regeneration do not have the function of solving the agglomeration effect of coated sand, which will cause dust to accumulate on the inner walls of the crushing chamber and the conveying pipeline due to electrostatic adsorption, and it is necessary to frequently stop the machine for cleaning, resulting in an increase in equipment maintenance costs.

[0030] Working principle: First, when the grinding machine 25 is started, the crushing wheel 27 can be driven to rotate through the power output shaft to crush the coated sand. When the main motor 12 is started, the eccentric wheel 7 can be driven to rotate through the power output shaft. When the eccentric wheel 7 rotates and fits with the rolling wheel 16, the movable plate 8 can be driven to swing. When the movable plate 8 swings to the left, the sliding plate 15 can be driven to move to the left through the swing plate 9. When the movable plate 8 swings to the right, the sliding plate 15 can be driven to move to the right through the swing plate 9. When the sliding plate 15 moves to the right, the crushing wheel 27 can be driven to move to the right. When the crushing wheel 27 moves to the right, it can move along the inner cavity of the rectangular opening, so as to realize the adjustment of the size of the crushed coated sand particles. Before the crushing work starts, the traction motor 36 can be started. When the traction motor 36 is started, the two driving grooved pulleys 35 can be driven to rotate through the power output shaft. When the two driving grooved pulleys 35 rotate, the two driven grooved pulleys 33 can be driven to rotate through the two belts 34. When the two driven grooved pulleys 33 rotate, the two winding wheels can be driven to rotate through the adjacent transmission rods 32. When the winding wheel rotates, the folding plate 28 can be driven to swing by pulling the pull rope 31. When the folding plate 28 swings, the vertical pipe 38 can be driven to turn 90 degrees. When several coating cottons 37 are in contact with the inner wall of the grinding box 5, an anti-static coating can be applied to the inner wall of the grinding box 5. By starting the ion wind rod, the charge of the coated sand at the position of the feed pipe 4 can be neutralized.
