Technical Field

[0001] This utility model belongs to the field of crusher technology, specifically relating to a multi-stage crushing and processing equipment for EPDM plastic granules. Background Technology

[0002] EPDM plastic granules are synthetic rubber granules copolymerized from ethylene, propylene and diene monomers. They are widely used in sports fields, playgrounds, building waterproofing and other fields. When recycling and processing EPDM plastic granules, crushing equipment is required to crush them.

[0003] In commonly used crushing devices, EPDM plastic granules are placed directly inside the crusher. To ensure crushing efficiency, the cutting edges of the crushing blades are designed to be relatively thin. In the initial stage of crushing, when the EPDM plastic granules are large and come into contact with the blades, the impact on the blades is greater, which will affect the service life of the blades.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 and 2As shown, a multi-stage crushing and processing equipment for EPDM plastic granules includes an outer cylinder 1 and crushing components 2. There are several crushing components 2, which are arranged sequentially from top to bottom. Two adjacent crushing components 2 are interlocked and connected. A drive component 3 is fixedly installed at the bottom end of the bottom crushing component 2. Several U-shaped support members 4 for supporting the crushing components 2 are fixedly connected to the bottom end of the inner wall of the outer cylinder 1. The several U-shaped support members 4 are equidistantly distributed around the axis of the outer cylinder 1.

[0021] According to the above structure, several crushing components 2 are installed sequentially from the bottom to the top of the outer cylinder 1. Two adjacent crushing components 2 are engaged and connected. In use, plastic granules are put into the interior of the outer cylinder 1 from the top. The plastic granules are first crushed by the top crushing component 2, and then fall downwards until they are finally crushed by the bottom crushing component 2.

[0022] like Figure 1 As shown, a conical hopper 11 is fixedly connected to the bottom end of the outer cylinder 1, a discharge pipe 12 is fixedly connected to the bottom end of the conical hopper 11, and support legs 13, which are equidistantly distributed around the axis of the outer cylinder 1, are fixedly connected to the bottom end of the outer cylinder 1.

[0023] According to the above structure, the crushed plastic granules are discharged through the discharge pipe 12 along the conical hopper 11.

[0024] like Figure 3 As shown, the crushing assembly 2 includes a base plate 21, a cylinder 22 fixedly connected to the top of the base plate 21, filter holes 23 evenly distributed on the surface of the cylinder 22, a feed hopper 24 fixedly connected to the top of the filter holes 23, slots 25 evenly distributed around the axis of the feed hopper 24 at the top of the feed hopper 24, support rods 26 evenly distributed around the axis of the cylinder 22 fixedly connected to the bottom of the side wall of the base plate 21, the support rods 26 engaging with the corresponding slots 25, a shaft 27 rotatably connected to the middle of the base plate 21 via a bearing, blades 210 evenly distributed on the side wall of the shaft 27, a slot 28 at the bottom of the shaft 27, and a chair protrusion 29 fixedly connected to the top of the shaft 27.

[0025] According to the above structure, during use, plastic granules enter the inside of cylinder 22. After the shaft 27 rotates, it drives the blade 210 to rotate, crushing the plastic granules. The crushed plastic granules are reduced in size and fall into the next cylinder 22 through the filter holes 23. The diameter of the filter holes 23 on several cylinders 22 decreases from top to bottom, and the thickness of the blades 210 on several shafts 27 decreases from top to bottom, thereby improving the service life of the blades 210. During installation, the bottom crushing component 2 is supported by the support rod 26 inserted into the U-shaped support 4. When adjacent crushing components 2 are connected, the support rod 26 of the upper crushing component 2 is inserted into the slot 25 of the lower crushing component 2, preventing relative rotation between the two adjacent crushing components 2.

[0026] like Figure 2 and 3 As shown, the drive assembly 3 includes a base plate 31 fixedly connected to the bottom end of the corresponding base plate 21. A motor 32 is fixedly connected to the bottom end of the base plate 31, and the output shaft of the motor 32 is fixedly connected to the bottom end of the corresponding shaft 27.

[0027] According to the above structure, during use, two adjacent shafts 27 are engaged and connected by a slot 28 and a chair protrusion 29. After the motor 32 drives the bottom shaft 27 to rotate, it drives all the shafts 27 to rotate, thereby crushing the plastic particles.

[0028] like Figure 2 and 3 As shown, the top of the inner wall of the outer cylinder 1 is threaded with a threaded ring 5.

[0029] According to the above structure, after the crushing component 2 is installed, the threaded ring 5 is screwed on to limit the crushing component 2 and prevent the crushing component 2 from moving upward.

[0030] The working principle of this utility model is as follows: Several crushing components 2 are installed sequentially from the bottom to the top of the outer cylinder 1. Two adjacent crushing components 2 are engaged and connected. In use, plastic granules are fed into the inner cavity of the outer cylinder 1 from the top. The plastic granules are first crushed by the top crushing component 2, and then fall downwards until they are finally crushed by the bottom crushing component 2. The crushed plastic granules are discharged through the discharge pipe 12 along the conical hopper 11. In use, the plastic granules enter the inner cavity of the cylinder 22. After the shaft 27 rotates, it drives the blade 210 to rotate, crushing the plastic granules. The crushed plastic granules have a reduced particle size and fall into the inner cavity of the next cylinder 22 through the filter holes 23. The diameter of the filter holes 23 on the several cylinders 22 is... The thickness of the blades 210 on the shafts 27 decreases from top to bottom, thereby improving the service life of the blades 210. During installation, the bottom crushing component 2 is supported by the support rod 26 inserted into the U-shaped support 4. When adjacent crushing components 2 are connected, the support rod 26 of the upper crushing component 2 is inserted into the slot 25 of the lower crushing component 2 to prevent relative rotation between the two adjacent crushing components 2. During use, the two adjacent shafts 27 are connected by the slot 28 and the chair protrusion 29. After the motor 32 drives the bottom shaft 27 to rotate, it drives all the shafts 27 to rotate, thereby crushing the plastic particles.
