A pulverizer for pvc pipe recycling with drying function

Abstract

The invention relates to the technical field of PVC pipe recycling, in particular to a PVC pipe recycling pulverizer with a drying function, which adopts two-stage crushing, the primary crushing drives the screw auger to work through the rotating shaft, and crushes the PVC pipe at the same time. After that, secondary crushing is carried out through the crushing rollers in the secondary crushing barrel to ensure crushing efficiency; a storage pipe is connected to the discharge end of the primary crushing barrel, and a drying component is installed on the side of the storage pipe, and the primary crushed The PVC pipe falls into the storage pipe, and the fan heats the air through the heating chamber and passes it into the storage pipe to dehumidify and dry the PVC pipe; while the driving motor drives the driving shaft to rotate, the driving bevel gear and the driven bevel gear interact to drive The driven shaft rotates and drives the push-pull rod to reciprocate through the connecting rod. The push-pull rod periodically hits the secondary crushing cylinder to shake off the PVC particles adhered to the cylinder wall and reduce the residual amount.

Description

technical field [0001] The invention relates to the technical field of recycling PVC pipes, in particular to a pulverizer for recycling PVC pipes with a drying function. Background technique [0002] PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. It is cheap and widely used. Polyvinyl chloride resin is white or light yellow powder, which cannot be used alone and must be modified. PVC is an amorphous white powder with a small degree of branching and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products. [0003] PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floor...

AI Technical Summary

Problems solved by technology

[0005] PVC pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. It has strong corrosion resistance, easy bonding, low price, and hard texture. Advantages, but due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C, common in drainage, waste water, chemicals, heating fluids and cooling fluids, food, ultra-pure liquids, Applications for mud, gas, compressed air and vacuum systems

[0006] Due to the huge amount of PVC pipes used, but in many cases they are disposable. PVC pipes are often discarded directly after use, which will not only waste resources, but also pollute the environment, which does not meet the existing green economic requirements. requirements, on the other hand, the existing PVC plastic pipes are all made of new materials, which wastes a lot of materials and increases the production cost.

[0007] Therefore, the recycling of PVC pipes has always been of concern to people, but most of the existing recycling equipment is used separately. Among them, the device for crushing PVC pipes cannot fully crush PVC pipes, the crushing effect is poor, and the crushing efficiency is low. Collecting the crushed pipes is labor-intensive; on the other hand, there will be liquid in the PVC pipe during use. When crushing, the liquid will inevitably overflow and mix with the crushed particles, resulting in water on the surface of the particles, resulting in hanging. The condition of the wall, resulting in a large amount of residue in the crushing device
