Description

Scrap crusher for recycling waste plastic shells

Technical Field

The utility model relates to a crushed aggregates machine, especially waste plastic shell retrieves and uses crushed aggregates machine.

Background

A general secondary battery includes a plastic case, and the plastic case is formed by injection molding, but it is inevitable to generate inferior products during the injection molding process, which results in a large amount of waste of raw materials and an increase in production cost, and thus, the inferior plastic case needs to be crushed and then melt-processed again.

In the existing plastic shell crushers, plastic shells are directly thrown into a double-shaft shearing crusher for crushing, and because inferior plastic shells have higher hardness, the double-shaft shearing crusher can cause the blades to be quickly abraded directly; the crushed materials crushed by the double-shaft shearing crusher are generally recycled after large fragments are manually removed, and the operation is troublesome. Therefore, the existing plastic shell crushing machine has the problems of fast abrasion and troublesome operation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a scrap plastics shell retrieves and uses crushed aggregates machine. The utility model discloses not only can reduce the rate of wear, still have the more convenient advantage of operation.

The technical scheme of the utility model: the crushing machine for recycling the waste plastic shells comprises a rack, wherein a crushing barrel is fixed on the rack; a feed inlet is formed in the side face of the top of the crushing barrel, and a discharge outlet is formed in the bottom end of the crushing barrel; the bottom of the crushing barrel is connected with a horizontal double-shaft shearing crusher, and the middle part of the crushing barrel is connected with a hot air pipe which is obliquely and upwards arranged; the vibrating screen is fixed at a position, corresponding to the lower portion of the discharge port, on the rack, and a collecting tank is arranged below the vibrating screen.

In the crusher for recycling the waste plastic shells, the rack is fixed with the obliquely arranged conveying belt, and the top end of the conveying belt is arranged in the feeding port.

In the material crushing machine for recycling the waste plastic shells, the feeding hole is connected with a plurality of vertically arranged flexible blocking pieces.

In the material crushing machine for recycling the waste plastic shells, the position of the material crushing barrel corresponding to the opposite end discharge port is fixed with the switch valve.

Compared with the prior art, the utility model has the advantages that the hot air pipe is arranged in the middle of the crushed aggregate barrel, so that the plastic shell entering from the top of the crushed aggregate barrel is heated by hot air firstly, thereby reducing the hardness of the plastic shell, facilitating the subsequent double-shaft shearing crusher to crush the plastic shell and reducing the abrasion speed; and a vibrating screen is arranged below the discharge port of the crushed material barrel, so that large fragments in the crushed materials can be conveniently removed after the crushed materials are crushed by the double-shaft shearing crusher, and the successfully crushed plastics can be collected by a collecting tank. In addition, in the utility model, the defective plastic shell is fed into the feed inlet at the top of the material crushing barrel through the conveyer belt, so that manual operation is not needed, and the operation is more convenient; the feeding port is connected with a plurality of vertically arranged flexible blocking pieces, so that the feeding of the conveying belt is not hindered, the escape of internal hot gas is avoided as far as possible, and the energy consumption is reduced; the feed opening and closing valve at the position of the discharge opening at the bottom of the crushed material barrel is used for controlling the feeding, so that the crushed materials can be fed in batches, and the influence of the butt joint of the crushed materials on the normal operation of the vibrating screen is avoided. Therefore, the utility model discloses reduce the rate of wear, still have the operation more convenient and the lower advantage of energy consumption.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The crusher for recycling the waste plastic shells comprises a frame 1, wherein a crushing barrel 2 is fixed on the frame 1, and the crushing barrel is fixed on the frame 1; a feed inlet 3 is arranged on the side surface of the top of the crushed material barrel 2, and a discharge outlet 4 is arranged at the bottom end of the crushed material barrel 2; the bottom of the crushing barrel 2 is connected with a horizontal double-shaft shearing crusher 5, and the middle part of the crushing barrel 2 is connected with a hot air pipe 6 which is obliquely and upwards arranged; a vibrating screen 7 is fixed at a position on the rack 1 below the discharge port 4, and a collecting tank 8 is arranged below the vibrating screen 7.

A conveying belt 9 which is obliquely arranged is fixed on the rack 1, and the top end of the conveying belt 9 is arranged in the feeding hole 3; the feed inlet 3 is connected with a plurality of vertically arranged flexible baffle sheets 10; and a switch valve 11 is fixed at the position of the crushing barrel 2 corresponding to the discharge port 4 at the opposite end.

The working principle is as follows: the operator places the defective plastic shells on the conveyer belt 9 on the frame 1, and the conveyer belt 9 sends the defective plastic shells to the feeding hole 3 at the top of the crushed aggregates barrel 2; at the moment, the defective plastic shell pushes a plurality of flexible blocking pieces 10 which are vertically arranged to fall into the material crushing barrel 2, is heated and softened by hot air blown upwards by the hot air pipe 6, is crushed by the double-shaft shearing crusher 5 and falls into the bottom of the material crushing barrel 2; the staff regularly opens the ooff valve 11 of 2 bottoms in garrulous storage bucket so that the crushed aggregates after smashing fall on vibrating screen 7 through discharge gate 4, vibrating screen 7 with the bold crushed aggregates stay vibrating screen 7 on, qualified crushed aggregates fall into collecting vat 8 downwards, accomplish crushed aggregates screening operation.
