Problems solved by technology

For drying and dehumidification equipment, a device for heating the airflow is required, usually a cylinder, and a heater is installed inside the cylinder, so that the airflow enters the heater and then heats it, and then discharges the material outside the cylinder. Heating and drying treatment is carried out, but such a structure will generate a higher temperature on the outer surface of the cylinder during long-term operation, which will affect the working status of other components inside the heating equipment

Abstract

The invention discloses an airflow heating device applied to material drying and dehumidification equipment. The airflow heating device comprises a heating box and a heater. The heating box comprisesan outer shell and an inner shell. A closed interlayer space is formed between the outer shell and the inner shell. A heating cavity is formed in the inner shell. The side wall of the inner shell is provided with at least one airflow channel communicating with the interlayer space and the heating cavity. The side wall of the outer shell is provided with an air inlet communicating with the interlayer space and the outside. The side wall of the inner shell is connected with an air outlet pipe. One end of the air outlet pipe communicates with the heating cavity, and the other end of the air outlet pipe penetrates the outer shell to the outside. The heater is arranged on the heating box and used for conducting heating treatment on airflow flowing through the heating cavity. According to the technical scheme of the airflow heating device, the situation that a large amount of heat is prone to being generated in equipment, and the work states of other components are influenced is not likely to happen, and heat can be more efficiently reserved in the heating cavity.

Description

technical field [0001] The invention relates to the technical field of drying and dehumidifying equipment for plastic particles, in particular to an airflow heating device. Background technique [0002] As society's awareness of environmental protection continues to increase, plastic recycling is becoming more and more widespread. The main process is to crush plastic blocks, and then further make granular materials, and then put them into the injection molding machine after drying and dehumidification process. It is reused in the material mouth. For drying and dehumidification equipment, a device for heating the airflow is required, usually a cylinder, and a heater is installed inside the cylinder, so that the airflow enters the heater and then heats it, and then discharges the material outside the cylinder. Heating and drying treatment is carried out, but such a structure will generate a higher temperature on the outer surface of the cylinder during long-term operation, wh...
