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 proc...

Embodiment 1

[0015] Example 1 Screening of ground material

[0016] Now in conjunction with the accompanying drawings to illustrate, the polyethylene floor material is added to the hopper 1, and the feeding speed controller 3 is turned on. The floor material starts to flow downward slowly due to its own weight, and the flowing material passes through the magnetic frame 2 to remove the iron present in the material. Metal impurities such as chips enter the primary screen 4, and the eccentric shaft is driven by the motor 7 to make the screens 4 and 5 reciprocate. Since the screen of the primary screen 4 is relatively thick, some strips, rods, stones, firewood, etc. After the garbage is blocked and cannot pass through, it will be discharged from the left outlet, and the unblocked materials will be further separated through the secondary screen 5. Since the secondary screen 5 is finer, the sand, dust, and stones with finer particle sizes Impurities such as non-magnetic metals are sieved and dis...

Embodiment 2

[0017] Example 2 Screening of crushed material

[0018] Now with reference to the accompanying drawings, the polyethylene crushed material is put into the feeding hopper 1, and the feeding speed controller 3 is turned on. The crushed material starts to flow downward slowly due to its own weight, and the flowing material passes through the magnetic frame 2 to remove the iron existing in the material. Metal impurities such as swarf enter the primary screen 4, and the eccentric shaft is driven by the motor 7 to make the screens 4 and 5 reciprocate. Since the screen of the primary screen 4 is relatively thick, some strips, filaments, large particles, etc. Irregular broken materials are blocked and cannot pass through and are discharged from the left outlet. The unblocked materials are further separated through the secondary screen 5. Since the secondary screen 5 is finer, the particle size is finer and the chip dust, filamentous Irregular broken materials such as strips, strips, e...

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...
