Environment-friendly vacuum pump system of molding machine

Abstract

The invention discloses an environment-friendly vacuum pump system. The system comprises a common skid-mounted base and a purified water cooling water tank, wherein the purified water cooling water tank is installed on the outer wall of the upper end of the common skid-mounted base, and a purified water tank and a sediment water tank are organically combined with a circulating water pump through avacuum water pump to achieve the effect of purifying water; and then the primary raw water formed by mixing low molecules or water vapor and the like released by an extruder or a granulator materialin a hot melting state is pretreated by a filtering and purifying system in a raw water purifying water tank, so that secondary raw water is formed after pretreatment; the secondary raw water is purified by four purification channels to form purified water; the purified water is cooled by a purified water cooling water tank, and the purified water with higher temperature is cooled to normal temperature; and finally, the purified water flows into a purified water cooling water tank through a circulating water pipe and is used as circulating water of a vacuum water pump, so that the repeated closed-loop use effect is achieved. The technical scheme is convenient for cyclic utilization, and the treated circulating water is free of any pollution and has important environmental protection significance.

Description

technical field [0001] The invention belongs to the related technical field of plastic processing, and in particular relates to an environment-friendly vacuum pump system for plastic machines. Background technique [0002] The plastic granulator is mainly used for processing waste plastic films, woven bags, agricultural convenience bags, pots, barrels, beverage bottles, furniture, daily necessities, etc. It is suitable for most common waste plastics and is the most widely used in the waste plastic recycling industry. The most widely used and most popular plastic recycling processing machinery. When the plastic granulator is working, the plastic is fed from the hopper, and the hopper smoothly falls onto the screw, and is bitten by the screw thread. With the rotation of the screw, the thread is forced to advance towards the machine head, forming a mechanical conveying process. When the plastic runs from the feed port to the machine head, due to the gradual reduction of the th...
