Description

Technical Field

[0001] The utility model belongs to the technical field of heating devices, and particularly relates to a heating device with high thermal energy utilization rate. Background Art

[0002] In industrial production and other fields, it is often necessary to use a heating device to heat materials. A heating device is a device that can convert energy in the form of electrical energy, thermal energy, chemical energy, etc. into thermal energy. It is usually composed of a heating element and a shell. The heating element is the part that generates thermal energy and can be a resistance wire, a heating element, an electron tube, a semiconductor device, etc.

[0003] There are many types of heating devices on the market. For example, a material heating device for construction engineering is disclosed on the China Patent Network, and its publication number is CN217746629U. Although this heating device can be used to heat materials, it has some defects and shortcomings that need to be improved: (1) Most of the existing heating devices heat the materials from the bottom. The hot air generated during heating will gradually rise and concentrate on the top of the heating device due to its light weight. However, it is often difficult for the existing heating devices to utilize the hot air concentrated on the top, thereby reducing the utilization rate of thermal energy; (2) When the existing heating devices heat the materials, the heat source is often poorly sealed, so that the heat energy generated at the heat source is easy to diffuse and lose, and it is difficult to fully transfer to the surface of the material, resulting in uneven heating of the material, thereby reducing the heating effect of the material; (3) Most of the existing heating devices are integrated structural designs, and the relevant heating components are often fixed on the entire device and difficult to disassemble at will. When the heating device fails, it is not convenient to repair and replace the heating components separately, and the entire heating device can only be scrapped, which not only increases the maintenance cost of the heating device, but also causes waste of resources. Therefore, in view of the above problems, the utility model provides a heating device with high thermal energy utilization rate, which is of great significance. Utility Model Content

[0004] The utility model provides a heating device with high heat energy utilization rate. The electric heating wire in the heating groove can generate heat so as to heat the material on the heating table. The hot air generated during heating can be guided from the top of the heating bin to the heating table through the heat collecting component so as to make full use of the heat energy, thereby greatly improving the utilization rate of the heat energy and avoiding the waste of the heat energy. The heat source in the heating groove can be sealed by the sealing block so as to prevent the heat generated by the electric heating wire from escaping through the gap and causing the heat energy to diffuse and lose. The heat generated by the electric heating wire can be fully absorbed by each heat conducting sheet and the heat can be transferred to the sealing block and the heating table. The bottom of the heating table effectively expands the heating area and range of the material, thereby further improving the heating effect of the material; the heating tank can be positioned through the cooperation between the stud and the nut, so that the heating tank can be firmly fixed on the support plate, and when the relevant heating component in the heating tank fails, the heating tank can be removed from the support plate by unscrewing the nut, and the heating chamber can be taken out, so that the relevant heating component can be separately inspected and replaced without scrapping the entire heating device, thereby effectively reducing the maintenance cost of the heating device, avoiding the waste of resources, and being beneficial to energy conservation and environmental protection.

[0038] The working principle of the utility model is:

[0039] When the utility model is in use, the heated material is first placed on the heating table 10, and then the electric heating seat 8 in the heating groove 7 is connected to an external power supply, and the warehouse door 4 is closed. The electric heating seat 8 can be used to supply power to the electric heating wire 9, and the electric heating wire 9 can generate heat after being energized.

When the material on the heating table 10 is heated, the sealing block 13 at the bottom of the heating table 10 can be inserted into and attached to the inner wall of the heating groove 7. At this time, the sealing block 13 can be used to seal the heat source in the heating groove 7, thereby effectively preventing the heat generated by the electric heating wire 9 from escaping through the gap and causing the heat energy to diffuse and lose, thereby avoiding uneven heating of the material. A plurality of heat conducting sheets 14 are arranged at the bottom of the sealing block 13, and each heat conducting sheet 14 can fully absorb the heat generated by the electric heating wire 9 and transfer the heat to the sealing block 13 and the bottom of the heating table 10 The heating area and range of the material are effectively expanded, thereby further improving the heating effect of the material. When the hot air generated during heating rises to the top of the heating bin 3, the heat energy in the hot air can be introduced into the heat conduction cavity 20 in the heat collection bin 19 through the heat collection cover 22. After the heat energy in the hot air enters the heat conduction cavity 20, it can be diffused to the heating table 10 through each heat conduction pipe 23, and cover the entire heating table 10 from both sides, so as to make full use of the heat energy, thereby greatly improving the utilization rate of heat energy and avoiding the waste of heat energy. When the relevant heating components in the heating tank 7 fail, the heating tank 7 can be removed from the support plate 1 by unscrewing the nut 18, and the heating bin 3 can be taken out, so that the relevant heating components can be separately inspected and replaced without scrapping the entire heating device, thereby effectively reducing the maintenance cost of the heating device, avoiding the waste of resources, and being beneficial to energy saving and environmental protection.
