Detailed ways

Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.

Example 1

As shown in Figures 1-3, a shearing and tearing metal-plastic selective crushing and separating device includes a material inlet 7, a casing 9, a material outlet 8, roller shafts 11, 12, and gear motors 131 and 132 ; The material inlet 7 is set on the upper part of the shell 9, and the bottom of the shell 9 has a material outlet 8; the roller shaft 11 and the roller shaft 12 are arranged in parallel in the shell 9 and are located on the same horizontal plane.

In the device, the structure and connection mode of the two rollers are consistent, and the device of the present invention is further introduced mainly by taking the roller 11 as an example.

Roller shaft 11 is a cylindrical roller with openings at both ends, and its material is seamless steel pipe, and its diameter and wall thickness are determined according to the design capacity;

Several equal cutters 21 and springs 31 are arranged on the surface of the roller shaft 11, and the number and positions of the cutters 21 are determined according to the processing object and production capacity. Cutter 21 is a grab-type or claw-type with a wide bottom and a narrow top, which has functions such as grasping, tearing, and cutting. The spring modulus of the spring 31 is determined according to the mechanical strength of the metal contained in the processed material, and the spring 31 is a disc spring. The cutter 21 and the bracket 41 are connected by a pin shaft, the bracket 41 is fixed on the surface of the roller shaft 11, and the cutter 21 can move vertically along the pin shaft; the spring 31 is arranged in a self-made groove on the roller surface, and the bottom of the spring 31 is embedded in the groove. The upper part of the spring is bolted to the cutter 21; the connection part between the cutter and the spring 31 is square; both the cutter 21 and the spring 31 can be replaced quickly.

The central shaft 61 (solid shaft) passes through the steel plate 16 vertically and is fixed on both ends of the roller shaft 11 by welding. The size of the central hole of the steel plate 16 is the diameter of the central shaft 61, and one or more ribs can be set in the middle of the roller for reinforcement. The two ends of the central shaft 61 are fixedly supported by bearings 51 and 53 respectively, and the bearings 51 and 53 are fixed on the channel steel frame 161, wherein only the bearing 51 is connected with the pulley 101; the central shaft 61 is connected with the pulley 101 through the bearing 51, and the pulley 101 passes through Belt 111 is connected with drive wheel 121, and drive wheel 121 is connected with reduction motor 131, thereby reduction motor 131 can drive central shaft 61 and roller shaft 11 work by driving pulley 101; on the feet 152 .

Working principle: before the device is started, the distance between the roller shaft 11 and the roller shaft 12 of the device is adjusted according to the composition and structure of the material to be processed. After adjustment, the reduction motors 131, 132 are started, and the pulleys 101, 102 are driven to rotate through the two belts, thereby driving the central shafts 61, 52 to make the roller shaft 11 and the roller shaft 12 move at the same speed. After idling and stabilizing for a few minutes, the material (metal and plastic composition) is fed from the material inlet 7, and several knives on the two rollers immediately bite, tear, and cut the plastic component (small hardness) on the surface of the material. When the particle size is smaller, it is discharged from the discharge port 8, and the springs 31 and 32 are compressed accordingly to generate partial displacement; but when the tool touches the metal component (high hardness), the spring is compressed to the limit, and the When the distance D between the corresponding cutters 21' and 22' of the two rollers increases, if the distance D is greater than the diameter or thickness of the metal component, the metal part will fall by gravity and be discharged from the discharge port 8, so far Finish selecting the broken function. After the metal is selectively avoided, the spring and knife return to their original shape.

In a specific embodiment, the selective crushing and separation device is used to process waste toner cartridges (the shell is a plastic part, and the interior is composed of iron plates, metal photosensitive drums, etc.), with a designed production capacity of 500kg/h, a roller shaft diameter of 400mm, and a roller wall thickness of 8mm. The power of the frequency modulation deceleration motor is 2*4Kw, and the roller speed is 40-60rpm. The effect of choosing crushing and separation is good, and 100% separation of metal and plastic can be realized.

In the embodiment, the selective crushing and separation device can be used for small electronic waste, etc., and can realize the purpose of energy saving and consumption reduction in the resource treatment process and efficient separation and recovery of resources. The greater the difference in mechanical strength between metal and plastic, the more obvious the effect of selective crushing and separation.

The above description is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification made to the above implementation method according to the technical essence of the utility model is equivalent to changes and modifications. All belong to the scope of the technical solution of the utility model.
