Multi-channel air-exchangable pressure-discharged temperature-controlled melting furnace for recycling plastic

Abstract

The invention discloses a multi-channel air-exchangable pressure-discharged temperature-controlled melting furnace for recycling plastic, the melting furnace comprises a preparation chamber and a melting chamber, wherein an electric heating layer is installed inside the side wall of the preparation chamber, a fixed connecting frame is fixed above the preparation chamber, the outer side of the melting chamber is provided with an outer heat-insulating electric heating protection cylinder, and the melting chamber is located above the fixed connecting frame. The multi-channel air-exchangable pressure-discharged temperature-controlled melting furnace achieves the purpose of continuous intermittent heating of the plastic in the preparation chamber through the uniformly-arranged electric heatingframes and electric heating nets installed on the electric heating frames, so that the plastic in the preparation chamber can be kept in a fluid state at all times, and the plastic is better stored inthe preparation chamber accordingly. When entering the preparation chamber, the plastic first enters through a material through pipe, and the plastic can be ensured in the fluid state after contactedwith transition thermalization of a transition thermalization tube. The plastic is prevented from condensation on the inner wall of the material through pipe to cause blocking of the material throughpipe.

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.
