A multi-channel inlet, ventilating, exhausting, pressure-controlled and temperature-controlled smelting furnace for recycling plastics

Abstract

The invention discloses a multi-channel smelting furnace capable of ventilating, exhausting, pressure-relieving and temperature-controlled recycling of plastics, which includes a preparation chamber and a melting chamber. There is a fixed connection frame, and an external thermal insulation electric heating sleeve is arranged on the outside of the melting chamber, and the melting chamber is located above the fixed connection frame. The multi-channel inlet, ventilated, pressure-exhausted and temperature-controlled smelting furnace for recycled plastic achieves the purpose of continuous and intermittent heating of the plastic in the preparation room through uniformly arranged electric heating racks and electric heating nets installed on each electric heating rack, making the preparation room The plastic in the chamber can be kept in a fluid state at all times, so that the plastic can be better stored in the preparation chamber. When the plastic enters the preparation chamber, it first enters through the feed pipe and contacts the transition heat of the transition heating tube. After heating, ensure its own flow state, and avoid the plastic from condensing on the inner wall of the feed pipe, which will cause the blockage of the feed pipe.

Description

technical field [0001] The invention relates to the technical field of smelting equipment for recycled plastics, in particular to a multi-channel smelting furnace capable of ventilation, exhaust, pressure, and temperature control for recycled plastics. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , pigments and other additives. In modern life, plastics have a high recycling capacity, so plastics have a very high recycling capacity. The preparation and production of plastics are generally completed by blow molding, but for recycled plastics, in order to obtain blow molding The fluid state of the matrix, and the plastic needs to be melted to change the plastic from the original solid state to a liquid state, which is convenient for subsequent processing. [0003] The mo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-channel melting furnace capable of ventilating and exhausting pressure and temperature control for recycling plastics, so as to solve the problem that no relatively centralized equipment can be integrated in the above-mentioned background technology. During production, As a result, the production line is stretched, time-consuming, and labor-intensive. When melting plastics, the temperature control effect is poor, and the specific performance is that the temperature rise range is small, the temperature rise speed is not fast enough and other defects.
