Description

Technical Field

[0001] The invention relates to the technical field of crushing processing, in particular to a turnover type crushing device for processing nano calcium powder. Background Art

[0002] Nano calcium powder is an important industrial raw material, widely used in plastics, rubber, coatings, medicine and other fields. Nano calcium powder can be used as an incremental filler to improve the rigidity, toughness, bending strength and other properties of plastic products, while improving the processing performance and surface finish of products. In the rubber system, nano calcium powder is easy to mix and disperse evenly, which can improve the softness of the rubber and the extrusion processing performance, so that rubber products have better surface smoothness, elongation, tensile strength, etc. Nano calcium powder, as an important inorganic filler and functional material, plays an important role in many fields.

[0003] The crushing process of nano calcium powder is a complex and delicate process. The production of nano calcium powder usually uses limestone or marble as raw materials. The grinding medium is used to impact and grind the material in a rotating cylinder to gradually refine the material. At present, the nano calcium powder raw material is injected into the crushing box and extruded and ground by the tooth groove meshing of two sets of linear structure crushing rollers. However, the crushing roller of this linear mechanism has a poor effect on the flipping of the raw material in the cavity. During the flipping process, the efficiency of driving the raw material to re-enter the tooth groove is relatively low. Each time the raw material enters the tooth groove for crushing is relatively small, which will lead to a relatively low crushing efficiency. The crushing roller tooth groove will also flatten the powder into a plate-like shape during the grinding of the raw material, and then attach it to the crushing roller, which greatly affects the effect of subsequent raw materials entering the tooth groove for grinding, thereby reducing the grinding efficiency.

[0043] See also Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 A feed hopper 15 is fixedly installed on the top of the crushing seat 20, and the feed hopper 15 is located on the top outer side of the crushing box 10. The nano calcium powder raw material is put into the crushing seat 20 through the feed hopper 15. The bottom of the crushing box 10 is connected with a universal roller and a supporting foot through a bottom plate 16. The bottom of the crushing seat 20 is connected with a fine filter plate 17, and the bottom of the fine filter plate 17 is connected with a discharge barrel 18. The crushing box 10 is provided with a discharge rack 19 at the bottom of the end away from the driving motor 11, and the discharge rack 19 is connected with the discharge barrel 18. The crushed nano calcium powder raw material enters the discharge rack 19 through the fine filter plate 17 and the discharge barrel 18, and the nano calcium powder is stored through the discharge rack 19.

[0044] The cleaning cylinder 60 is connected to an air inlet pipe 65 and an air outlet pipe 66 at one end away from the piston rod 64, and the cleaning cylinder 60 is connected to an air outlet pipe 66 on one side of the air inlet pipe 65. An air guide pipe 67 is installed on one side of the movable rod 35, and one end of the air guide pipe 67 is connected to the nozzle 61, and the other end of the air guide pipe 67 is connected to the air outlet pipe 66. The positive pressure air generated in the cleaning cylinder 60 is connected to the nozzle 61 to clean the arc groove 24 and the triangular crushing knife 23.

[0045] Working principle: The driving motor 11 drives the first gear 12 to cooperate with the chain 14 to rotate the second gear 13 synchronously, and the first gear 12 drives the crushing roller 22 to rotate. The meshing of the rotating gear 25 drives the crushing roller 22 to grind and crush the nano-calcium powder raw material. The two adjacent triangular crushing knives 23 on the crushing roller 22 cooperate with the crushing support seat 21 to grind the nano-calcium powder raw material in an interlaced manner. At the same time, the interlaced activities of the triangular crushing knives 23 staggered between the two adjacent crushing rollers 22 also complete the grinding of the nano-calcium powder raw material. During the rotation process, the arc-shaped slots 24 on the triangular crushing knives 23 continuously lift and flip the raw materials in the crushing seat 20 from the bottom to the top side of the crushing roller 22. The powdered nano-calcium powder raw material enters the discharge barrel 18 through the fine filter screen and is discharged through the discharge rack 19.

[0046] The crushing roller 22 drives the first bevel gear 52 to rotate. When the first bevel gear 52 rotates, the third bevel gear 55 is driven to move synchronously through the connecting shaft 53 and the second bevel gear 54. The third bevel gear 55 drives the supporting shaft 50 to rotate. The rotating disk 51 at the top of the supporting shaft 50 drives the push plate 40 on the limiting base 42 to reciprocate horizontally through the hinge rod 57, the T-shaped fixing ring 56 and the hinge seat 58.

[0047] When the push plate 40 moves to the rightmost end of the crushing box 10, the positioning rod 41 moves in the rotating hole 33 on the L-shaped rotating plate 32, so that the L-shaped rotating plate 32 rotates in the fixed rotating shaft 31, and the other end of the L-shaped rotating plate 32 cooperates with the U-shaped movable frame 34 through the rotating hole 33 to push the movable rod 35 horizontally, so that the arc movable block 30 under the movable rod 35 enters the arc groove 24 of the triangular crushing knife 23, and pushes down the powder pressed into a plate mass on the arc groove 24. At the same time, the raw material driven by the arc groove 24 on the triangular crushing knife 23 is turned over to the top of the crushing roller 22, and the raw material is continuously turned back and forth between the crushing rollers 22. When the push plate 40 moves to the leftmost side, it will enter the gap between the two adjacent triangular crushing knives 23, until the top of the next arc groove 24 of the triangular crushing knife 23 moves, the arc movable block 30 enters again to push, and the three groups of arc grooves 24 in the triangular crushing knife 23 are pushed at intervals in this way;

[0048] Similarly, the rotating disk 51 supporting the bottom end of the rotating shaft 50 drives the piston plate 63 in the cleaning cylinder 60 to reciprocate through the hinge rod 57, the T-shaped fixing ring 56 and the hinge seat 58. When negative pressure is generated in the cleaning cylinder 60 through the piston plate 63, gas is filled through the air inlet pipe 65. When positive pressure is generated in the cleaning cylinder 60 through the piston plate 63, air is blown to the nozzle 61 through the air outlet pipe 66 and the air pipe, so that the nozzle 61 cleans the powder in the arc groove 24 of the triangular crushing knife 23, thereby improving the flipping effect of the subsequent arc groove 24 on the bottom raw material.
