Raw material screening device for PE water supply pipe production and manufacturing

Abstract

The raw material screening device for PE water supply pipe production and manufacturing comprises a bottom plate, a screening box, a polyethylene particle distribution box, a viscosity reduction type feeding mechanism and a molten material uniform screening mechanism, the screening box is arranged above the bottom plate, and the polyethylene particle distribution box is arranged on the upper wall of the portion, on one side of the screening box, of the bottom plate; the viscosity reduction type feeding mechanism is arranged on the polyethylene particle distribution box, the molten material uniform screening mechanism is arranged on the screening box, and the viscosity reduction type feeding mechanism comprises a feeding screening mechanism and a low molecule spraying mechanism. The invention belongs to the technical field of PE water supply pipe production, and particularly relates to a raw material screening device for PE water supply pipe production and manufacturing. According to the raw material screening device for PE water supply pipe production and manufacturing, polyethylene particles are screened and used in a separation mode, and the melt viscosity can be effectively reduced, and flowing storage can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of PE water supply pipe production, in particular to a raw material screening device for the production and manufacture of PE water supply pipes. Background technique [0002] PE water supply pipe is a water pipe structure made of polyethylene as the main raw material. The polyethylene material has the characteristics of high strength, corrosion resistance, non-toxicity, etc. PE water supply pipe is widely used, and because it will not rust, it is an alternative to It is an ideal pipe for ordinary iron water supply pipes. Before the injection molding raw materials of the pipes enter the injection molding machine, in order to ensure that the raw materials can be completely melted within the specified melting time, the particle size of the PE raw materials entering the injection molding machine needs to be strictly controlled. Avoid the simultaneous addition of larger particle size and smaller particle size ma...

AI Technical Summary

Problems solved by technology

[0003] However, there are many types of PE water supply pipes, and the raw materials of different types of PE water supply pipes are also different, and the particle sizes of common PE raw materials such as PE80 and PE100 are also different, so when the staff is on different models When raw materials are added, it is necessary to replace the screen for sieving raw materials. Since the screening device is generally large, it is very time-consuming and laborious to replace the screen.
