Security-enhanced ventilative pressure discharge and temperature control plastic recycling smelting furnace

Abstract

The invention discloses a security-enhanced ventilative pressure discharge and temperature control plastic recycling smelting furnace and relates to the field of plastic recycling equipment. The smelting furnace comprises a preparation chamber, a partition board and a material melting chamber. The left and right sidewalls of the preparation chamber are both internally provided with electric heating layers. An external heat insulation electric heating guard barrel is arranged on the outer side of the material melting chamber. A cavity is formed in the position, close to the left side, of the interior of the partition board. The left side of the cavity is connected with an electromagnetic control mechanism. The right side of the cavity is connected with a starting mechanism. The electromagnetic control mechanism is in threaded connection with the starting mechanism. The smelting furnace conducts continuous intermittent heating on plastics in the preparation chamber so that the plastics in the preparation chamber can be kept in a fluidic state all the time, and the plastics is stored well. When the plastics gets into the preparation chamber to make contact with the transition thermalization temperature of a transition thermalization tube, the fluidic state of the plastics is ensured. In the starting process, an operator can be protect against direct contact with a high-voltage switch for turning on a machine starting device, and the operation environment is safer.

Description

technical field [0001] The invention relates to the field of recycling plastic equipment, in particular to a recycling plastic melting furnace capable of ventilating, exhausting, pressure-relieving and temperature-controlled with enhanced safety. 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 modern p...

Problems solved by technology

[0003] The modern plastic recycling and smelting process contains many processes, including crushed materials, heating and melting, fluid storage and other processes, but for these processes, there is no relatively centralized equipment that can integrate them. During production, it leads to The production line is elongated, which consumes man-hours and manpower, and there are corresponding restrictions on the reform of the production process. When melting plastics, the control effect on temperature is poor, and the specific performance is that the temperature rise range is small and the temperature rise rate Defects such as not fast enough, in the smelting production process, such production defects are likely to cause incomplete smelting and correspondingly low efficiency. On the other hand, the machines in the equipment used in these processes use high voltage. If there is direct operation Personnel switching operations are likely to cause safety accidents
