Description

Technical Field

[0001] The utility model relates to the technical field of industrial hot air blowers, in particular to an industrial hot air blower heater. Background Art

[0002] Industrial hot air blowers have a wide range of applications. They are used in a wide range of processes, including heating, curing, aging, welding, drying, and heating, in the electronics, food, pharmaceutical, printing, packaging, rubber, glass, cleaning, heat treatment, and coating industries. They are also the optimal hot air source for automated facilities like precision hot air conveying furnaces, drying ovens, drying rooms, drying tunnels, shrinking machines, packaging machinery, and industrial cleaning equipment. The hot air in industrial hot air blowers primarily comes from the heating of their heaters. With the development of modern technology, the functions of these heaters are also increasing.

[0003] However, the existing industrial hot air blower heaters are directly installed at the end or inside of the hot air blower during use, and are connected to the air inlet device. The air flow is preheated by the internal heating structure, and then heated to form hot air that is blown out. During the heating process, since the ordinary electric heater does not have a heat insulation function, the internal temperature will continue to rise, and then be transmitted to the equipment casing and continuously transmitted to the outside, resulting in the temperature of the interior and outer surface of the hot air blower continuing to rise, which can easily cause the equipment to be damaged by high temperature, and can also easily cause the outer surface temperature to be too high and burn the staff. In this regard, this design proposes an industrial hot air blower heater. Utility Model Content

[0009] In one example, a docking groove is fixedly provided at an upper edge of one side of the shell, and a second dustproof net is installed on one side of the inner wall of the docking groove.

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0021] The examples are as follows:

[0022] The utility model provides Figure 1-4 An industrial hot air heater shown includes a housing 1 and a heat insulation mechanism 2 and a heat dissipation mechanism 3 both mounted inside the housing 1;

[0023] The heat insulation mechanism 2 includes a plurality of support shafts 201 fixed at equal distances on the inner wall of the shell 1, and a ventilation pipe 202 is fixed at one end of each support shaft 201. A heating wire 203 is fixed on the inner wall of the ventilation pipe 202. A vacuum groove 204 is opened at the edge of the inner wall of the ventilation pipe 202, and a plurality of annular water grooves 205 are sleeved on the outer wall of the ventilation pipe 202. The inner walls of each annular water groove 205 are interconnected. A water pump 206 is installed in the middle position of the top of the shell 1. Water pipes 207 are inserted at both ends of the water pump 206, and one end of the two water pipes 207 passes through the inner walls of both ends of the shell 1 and is connected to the inner walls of two of the annular water grooves 205. The vacuum groove 204 is opened at the edge of the inner wall of the ventilation pipe 202 to improve the heat transfer insulation performance of the ventilation pipe 202. At the same time, the annular water grooves 205 sleeved on the outer surface of the ventilation pipe 202 are interconnected. When the water flows, it contacts the outer surface of the ventilation pipe 202 and absorbs the heat emitted from its outer surface.

[0024] Furthermore, the heat dissipation mechanism 3 includes mounting grooves 301 opened at both ends of the bottom of the inner wall of the shell 1, and the inner walls of the two mounting grooves 301 are equipped with exhaust fans 302, and the exhaust fans 302 are installed in the mounting grooves 301 below the ventilation pipe 202, without contacting the ventilation pipe 202, reducing the impact of high temperature on them, and the exhaust fans 302 mainly assist the heat insulation mechanism 2 to quickly discharge the part of the heat that is not isolated and consumed.

[0025] A plurality of heat dissipation slots 303 are evenly spaced at the lower edges of both sides of the outer wall of the housing 1, and the inner wall of each heat dissipation slot 303 is connected to the inner walls of the two mounting slots 301 respectively. A first dustproof net 304 is fixed to the upper edge of the inner wall of the two mounting slots 301, and the first dustproof net 304 serves to protect the exhaust fan 302 from dust.

[0026] Furthermore, a docking groove 4 is fixedly provided at the upper edge of one side of the shell 1, and a second dustproof net 5 is installed on one side of the inner wall of the docking groove 4. After the blower 6 is docked with the docking groove 4 using screws, air enters through the docking groove 4, and the second dustproof net 5 in the docking groove 4 plays a role in filtering impurities.

[0027] A blower 6 is installed at one end of the docking groove 4, and an air outlet pipe 7 is inserted into the upper end of the other side of the shell 1, and one end of the air outlet pipe 7 passes through the inner wall of the shell 1 and is connected to one end of the ventilation pipe 202, and handles 8 are fixed on the edges of both sides of the top of the shell 1.

[0028] Working principle: When using the industrial hot air heater in this design, the blower 6 is started to let air into the housing 1, and the heating wire 203 in the ventilation pipe 202 is started so that the incoming airflow enters the ventilation pipe 202, is heated by the heating wire 203, and is then discharged from the air outlet pipe 7 to form hot air. During the heating process, the water pump 206 is started to continuously pump out and pump in the water flow in the annular water tank 205 through the water pipes 207 at both ends, forming flowing water inside the multiple annular water tanks 205. When the flowing water contacts the outer wall of the ventilation pipe 202, it effectively absorbs the heat therein. The heat is taken away by flowing, and the flowing water also consumes heat continuously while flowing, so that the water temperature will not be too high, and the increase in the temperature of the outer wall of the ventilation pipe 202 can be suppressed, so that the higher temperature will not spread outward, and the temperature inside and outside the shell 1 is reduced to prevent the equipment from being damaged by excessive temperature. At the same time, it also prevents the outer surface temperature from being too high and scalding the staff. In the process of the heater working, the exhaust fan 302 in the installation groove 301 is started to run to discharge part of the emitted heat through the heat dissipation groove 303, further reducing the temperature inside the equipment and improving the stability of the equipment operation.
