Description

A tooth-breaking and re-grinding waste PVC plastic secondary utilization processing device

technical field

The invention relates to the technical field of environmental protection equipment, in particular to a secondary utilization and processing device for waste PVC plastics with broken teeth and re-grinding.

Background technique

PVC was once the largest general-purpose plastic in the world, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials and fibers. Waste PVC can be reused after reprocessing, which can save resources on the one hand, and avoid pollution to the environment on the other hand.

For example, a plastic pipe milling and crushing machine proposed by CN 102794217 B mainly solves the technical problem that in the past, there are mainly two methods used in plastic pipe material crushing at home and abroad: one is to first use a shredder to shred the pipe material, Then use a crusher for crushing. This method requires high power, high noise and low output. For example, when crushing polyethylene PE pipes with a diameter of 800mm, the total power of the two machines is 180kw, and the output is about 4 tons in 8 hours. The second is to saw the pipes into sections, cut them into strips, cut them into pieces and put them into a crusher for crushing, and then granulate them. This method has a lot of dust, high noise and low output. Due to the reprocessing of PVC, it needs to be completely broken. , on the one hand, it can be melted quickly, and on the other hand, it can be quickly mixed with other elements, but in this technical solution, it is difficult to achieve the above effect only by milling the motor, and during the cutting process, some pipes may be due to their own shape problems or The problem of positional offset in the cutting process leads to the non-standard size. When the secondary processing of the non-standard pipe is carried out, it needs to be separated out to facilitate feeding, but the mechanism also does not have this function.
