Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a rapid heating device for raw materials of polyurethane energy-saving board equipment. Background Technique

[0002] The polyurethane energy-saving board is a highly energy-efficient building material with excellent heat insulation and preservation performance, which can significantly reduce building energy consumption. With its light weight, firmness and durability, it is widely used in building parts such as walls, roofs, floors, etc. The polyurethane energy-saving board also has characteristics such as fire prevention, flame retardance, environmental protection and energy conservation, which conform to the concept of sustainable development.

[0003] The existing heating devices for processing raw materials of medium and small-sized polyurethane energy-saving boards only heat through the middle heating pipe, with a relatively small heating range and a long heating time in the barrel, reducing the production efficiency of polyurethane energy-saving board equipment. Content of the Utility Model

[0004] In order to overcome the shortcomings that the existing polyurethane energy-saving board raw material processing device only heats through the middle heating pipe, with a small heating range and a long heating time, resulting in the difficulty in improving the production efficiency of polyurethane energy-saving board equipment, the utility model provides a rapid heating device for raw materials of polyurethane energy-saving board equipment.

[0005] A rapid heating device for raw materials of polyurethane energy-saving board equipment includes a tank body. A cavity is provided on the inner wall of the tank body, and a heating pipe is fixed in the cavity. It also includes a return pipe, a hot gas pipe, an exhaust pipe and a support. The return pipe is arranged above the tank body, the hot gas pipe is fixed and penetrates through the middle of the tank body. One end of the return pipe is connected to the cavity, and the other end is connected to the upper end of the hot gas pipe. The lower end of the hot gas pipe is connected with an exhaust pipe, and the exhaust pipe is fixed to the bottom of the tank body through a support.

[0006] Optionally, it further includes a heat exchange box. The heat exchange box is connected to the end of the exhaust pipe. A refrigeration conductor is arranged inside the heat exchange box, and the heat exchange box is provided with an emission port.

[0007] Optionally, a filter screen is arranged at the emission port of the heat exchange box.

[0008] Optionally, it further includes a maintenance ladder, and the maintenance ladder is fixedly connected to the side wall of the tank body.

[0009] Optionally, it further includes a thermometer. The thermometer is arranged on the side wall of the tank body, and the sensing end of the thermometer is located in the cavity.

[0010] Optionally, it further includes heat insulation cotton, and the heat insulation cotton is located outside the return pipe.

[0011] The utility model has the following advantages: The heating pipe is turned on to heat the heat exchange liquid, so as to increase the temperature of the inner wall of the tank. The steam with a higher temperature is introduced into the hot gas pipe through the return pipe. Since the hot gas pipe is located in the middle of the tank, the hot gas pipe will simultaneously heat the raw materials in the tank. By heating the side wall and the middle of the tank at the same time, the heating efficiency of the raw materials of the polyurethane energy-saving board is improved.

Detailed Embodiment

[0017] To make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the drawings. Just for clarification, the orientation terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the drawings of the utility model, and they are not specific limitations to the utility model.

[0018] Embodiment: A device for quickly heating the raw materials of a polyurethane energy-saving board equipment, as Figures 1 - 4 shown, includes a tank body 1. A cavity 2 is provided on the inner wall of the tank body 1. A heating pipe 3 is fixed in the cavity 2. It also includes a return pipe 4, a hot gas pipe 5, an exhaust pipe 6 and a bracket 7. Four return pipes 4 are arranged radially above the tank body 1. The hot gas pipe 5 is fixed and penetrates through the middle of the tank body 1. One end of each of the four return pipes 4 communicates with the cavity 2, and the other ends converge into one pipe and communicate with the upper end of the hot gas pipe 5. The outside of the return pipe 4 is sleeved with heat insulation cotton 14. The heat insulation cotton 14 can insulate the high-temperature steam in the return pipe 4 to prevent heat escape and reduce the heat recovery efficiency. The lower end of the hot gas pipe 5 is connected with an exhaust pipe 6. The exhaust pipe 6 is fixed to the bottom of the tank body 1 through a bracket 7.

[0019] As Figure 2 and Figure 4As shown in the figure, it further includes a heat exchange box 8. The heat exchange box 8 is connected to the end of the exhaust pipe 6. A refrigeration conductor 9 is provided inside the heat exchange box 8. The heat exchange box 8 is provided with an exhaust port 10, and a filter screen 11 is arranged at the exhaust port 10 of the heat exchange box 8 to prevent various impurities from escaping.

[0020] As Figure 1 shown in the figure, it further includes a maintenance ladder 12. The maintenance ladder 12 is fixedly connected to the side wall of the tank body 1, and the staff can perform post-maintenance and care on this device through the maintenance ladder 12.

[0021] As Figure 1 shown in the figure, it further includes a thermometer 13. The thermometer 13 is arranged on the side wall of the tank body 1, and the sensing end of the thermometer 13 is located inside the cavity 2. The temperature of the cavity can be intuitively displayed through the thermometer 13, and the staff can adjust the power of the heating pipe 3 according to the temperature indicated by the thermometer 13.

[0022] Working principle: The polyurethane energy-saving board raw materials are introduced into the tank body 1, and a sufficient amount of heat exchange liquid is added to the cavity 2. The heating pipe 3 is turned on to heat the heat exchange liquid, thereby increasing the temperature of the inner wall of the tank body 1, and heating the raw materials in the tank body 1 by means of contact heat exchange. When the heat exchange liquid is heated to a certain temperature, the steam at a higher temperature is introduced into the hot gas pipe 5 through the return pipe 4. Since the hot gas pipe 5 is located in the middle of the tank body 1, the hot gas pipe 5 will simultaneously heat the raw materials in the tank body 1. By heating the side wall and the middle of the tank body 1 simultaneously, the heating efficiency of the polyurethane energy-saving board raw materials is improved. The hot steam in the hot gas pipe 5 is discharged through the exhaust pipe 6, and the refrigeration conductor 9 can cool down the hot steam to prevent the hot steam from causing harm to external equipment or personnel due to high temperature after being discharged from this device.
