Polyethylene pipe broken material or drop material sorting and separating device

Abstract

The invention relates to a polyethylene pipe broken material or drop material sorting and separating device. The device comprises a machine frame and a flow filtration water tank, and is characterized in that: a discharging hopper, a primary screen and a secondary screen are arranged on the machine frame from the top to the bottom in turn; the flow filtration water tank is arranged below an outlet on one side of the secondary screen; both the primary screen and the secondary screen are connected with an eccentric shaft which is connected with a motor; and a magnetic frame is arranged in the discharging hopper. The device has the advantages that: by using the device, iron scraps, stones, sand and firewood in drop materials or the iron scraps, powder cutting scraps, and irregular broken materials such as strip-shaped broken materials, thread-like broken material and the like in broken materials can be separated from regular broken materials effectively to fulfill the aims of sorting and recycling; when the sorted drop materials and the broken materials are subjected to extrusion manufacturing after being dried and recycled, the phenomena of bridging, feed opening blockage, unstable wall thickness and the like are improved obviously; energy is saved; consumption is reduced; and production cost is remarkably reduced.

Description

technical field [0001] The invention relates to an automatic sorting and screening device for crushed polyethylene pipe material or ground material, specifically a device that uses simple vibrating screens, eccentric shafts, fans and other components to automatically distinguish broken material from impurities in the ground material by physical methods a device. Background technique [0002] Polyethylene resin is widely used in technical fields such as pipes, sheets, films, etc. due to its high toughness, sanitation, non-toxicity, and easy molding processing. It is a material with the widest range of use in the world. Due to the need for raw materials to be transported, dried, mixed, batched, and extruded during production, a certain amount of ground material will be produced to varying degrees. Recycling is difficult because impurities cannot be sorted. In addition, due to its high toughness, the waste products produced in the processing and production are prone to produc...

Problems solved by technology

[0002] Polyethylene resin is widely used in technical fields such as pipes, sheets, films, etc. due to its high toughness, sanitation, non-toxicity, and easy molding processing. It is a material with the widest range of use in the world. Due to the need for raw materials to be transported, dried, mixed, batched, and extruded during production, a certain amount of ground material will be produced to varying degrees. Recycling is difficult because impurities cannot be sorted

In addition, due to its high toughness, the waste products produced in the processing and production are prone to produce irregular objects such as powder, strip, wire drawing, granular, and chips during the crushing process, and these irregular crushed materials will directly lead to During the recycling process, defects such as bridging, blocking the feeding port, and unstable wall thickness have occurred, which have greatly affected the recycling of PE pipe crushed materials and virtually increased the production cost of the enterprise.

[0003] In the currently known patents and implementation technical solutions, only the iron filings in the ground material or broken material are simply separated, and it is not possible to separate the indistinguishable substances such as sediment, firewood, stones in the ground material, and irregular particles in the broken material. There is no effective separation method for materials that are difficult to recycle. Only the crusher process has been modified to effectively reduce the irregular broken materials, but it cannot effectively eliminate them.
