Embodiment Construction

[0008] The assembly line safe hot air heating system has a heating furnace 2, an insulation layer 1 is provided outside the heating furnace, and a guide rail 10 is arranged inside the heating furnace. The guide rail is installed on the support seat 9, and the pipeline chain plate 6 runs on the guide rail 10. A temperature transmitter is installed on the wall, two air supply nozzles 3 are installed on the two side walls of the heating furnace and above the chain plate of the assembly line, and PTC heaters 4 are respectively installed at the rear of the two air supply nozzles, and are connected to the air supply pipes 5 respectively. The air supply pipe 5 is connected with the regulating valve 7 and the blower fan 8 in turn.

[0009] The PTC heater 4 has a heater bracket 12, the two sides of the heater bracket are provided with PPS engineering plastic mounting brackets 15, and the heater bracket is provided with a PTC ceramic heating element 14, and the two sides of the PTC ceram...

Abstract

The safe hot blasting system has heating hearth with outer heat insulating layer, guide track inside the heart and installed on the support seat, stream line chain plate running on the guide track, temperature transducer on the hearth wall, two blasting nozzles over the chain plate and on the side walls, PTC heaters connected to blasting pipeline and in the back part of the two blasting nozzles, and blasting pipeline connected successively with regulating valve and blower. The present invention has PTC ceramic heating element to form combined heater, and owing to the positive temperature coefficient effect of semiconductor material the resistance of the PTC material will become greater obvisouly after the temperature is raised to some value, resulting in excellent thermostatic characteristic. The present invention has no lighting loss, input electric power reduced automatically with the raised environment temperature and other advantages.

Description

technical field [0001] The invention relates to a material heating device applied to an assembly line, in particular to an assembly line safe hot air heating system. Background technique [0002] The existing assembly line heating has been widely used in the heat treatment of metal materials, the rapid preservation of various fresh fruits, the aseptic automatic drying treatment of various tablets and powders in the pharmaceutical industry, the dehydration and preservation treatment of Chinese medicinal materials, and the heat setting of printed and dyed fabrics. , Stretching and drying, drawing forming of various films and plastic bags in the plastic industry, drying treatment of various grains before storage, greening of tea, dehydration of crop seeds, heat treatment of ferrite materials and tobacco In the industry, the water treatment of tobacco leaves and shredded tobacco, etc. To heat the objects on various devices on it, it is generally used to directly heat the furnac...
