[0003] In the prior art, the heating speed of the heating sleeve is slow. If the heating speed of the heating sleeve is too slow, the heating time in the production process will be prolonged. This may lead to a reduction in the overall efficiency of the production line, affecting the production speed and output of products. A slower heating speed means that it takes longer time and more energy to heat the medium to the target temperature, which will increase energy consumption and have an adverse impact on production costs.

[0004] Therefore, it is necessary to design a heating device for thermal production to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide a heating device for thermal production.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A heating device for thermal production, including an outer tube and an inner tube. The inner tube is placed inside the outer tube.

[0008] As a preferred technical scheme of the utility model, the driving structure includes a fixed seat, evaporation liquid, a sliding plug, a gas guiding cover and an exhaust port. The fixed seat is fixed on the outer tube and has a hollow structure. The evaporation liquid is stored inside the fixed seat. The sliding plug is hermetically and slidably connected inside the fixed seat. The gas guiding cover is fixed inside the fixed seat. The exhaust port is opened on the side of the fixed seat and is communicated with the inside of the fixed seat.

[0009] As a preferred technical solution of the present utility model, the air extraction structure includes an air suction seat, a rotating shaft, two rotating members, an air suction pipe and an exhaust passage. The air suction seat is fixed on the top surface of the fixed seat, and the air suction seat is of a hollow structure. The rotating shaft passes through the fixed seat and the air suction seat, and is rotatably connected between the rotating shaft and the fixed seat, and is rotatably connected between the rotating shaft and the air suction seat. The two rotating members are respectively fixed at both ends of the rotating shaft. One of the rotating members is located inside the fixed seat, and the other rotating member is located inside the air suction seat. One end of the air suction pipe is communicated with the air suction seat, and the other end is communicated with the area between the outer pipe and the inner pipe. The exhaust passage is opened on the air suction seat.

[0010] As a preferred technical solution of the present utility model, the rotating member includes a sleeve and a plurality of axial flow blades. The plurality of axial flow blades are all fixed on the sleeve, and the plurality of axial flow blades are circumferentially and arrayedly distributed.

[0011] As a preferred technical solution of the present utility model, the rotating member located inside the fixed seat is disposed opposite to the air guiding cover.

[0012] The present utility model has the following beneficial effects:

[0013] 1. Efficient heating process: Through the heating effect of the heating wire, the substance flowing inside the inner pipe can be quickly and accurately heated, ensuring the required heating temperature and stability, and improving the heating efficiency.

[0014] 2. Temperature control and stability: The outer pipe can effectively control and maintain the temperature of the outer pipe through the evaporation process of the evaporation liquid. This temperature control helps to maintain the stable heating state of the substance flowing inside the inner pipe and avoid the occurrence of overheating or overcooling phenomena.

[0015] 3. Enhanced heat transfer efficiency: When the temperature of the outer pipe rises to the boiling point of the evaporation liquid, the evaporation and vaporization of the evaporation liquid push the sliding plug to move, thereby driving the rotation of the rotating member. This process not only utilizes the evaporation heat effect, but also extracts the gas between the outer pipe and the inner pipe by driving the rotating member inside the rotating shaft and the air suction seat, thereby reducing the thermal conductivity of the area between the outer pipe and the inner pipe and further increasing the heating speed of the inner pipe.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a heating device for thermal production, comprising an outer tube 1 and an inner tube 2. The inner tube 2 is placed inside the outer tube 1. An electric heating wire 3 is arranged between the outer tube 1 and the inner tube 2. A driving structure is arranged on the outer tube 1. The driving structure includes a fixing seat 41, an evaporation liquid 42, a sliding plug 43, an air guide cover 44 and an exhaust port 45. The fixing seat 41 is fixed on the outer tube 1 and has a hollow structure. The evaporation liquid 42 is stored inside the fixing seat 41. The sliding plug 43 is hermetically and slidably connected inside the fixing seat 41. The air guide cover 44 is fixed inside the fixing seat 41. The exhaust port 45 is opened on the side of the fixing seat 41 and is communicated with the inside of the fixing seat 41. An air extraction structure is arranged on the driving structure. The air extraction structure includes a suction seat 51, a rotating shaft 52, two rotating members 53, a suction pipe 54 and an exhaust duct 55. The suction seat 51 is fixed on the top surface of the fixing seat 41 and has a hollow structure. The rotating shaft 52 passes through the fixing seat 41 and the suction seat 51. The rotating shaft 52 is rotatably connected to the fixing seat 41 and is rotatably connected to the suction seat 51. The two rotating members 53 are respectively fixed at both ends of the rotating shaft 52. One of the rotating members 53 is located inside the fixing seat 41, and the other rotating member 53 is located inside the suction seat 51. The rotating member 53 includes a sleeve and a plurality of axial flow blades. The plurality of axial flow blades are all fixed on the sleeve and are circumferentially arranged in an array. The rotating member 53 located inside the fixing seat 41 is arranged opposite to the air guide cover 44. One end of the suction pipe 54 is communicated with the suction seat 51, and the other end is communicated with the area between the outer tube 1 and the inner tube 2. The exhaust duct 55 is opened on the suction seat 51.

[0023] The specific working principle of the present invention is as follows:

[0024] When the heating sleeve for thermal production proposed by the present utility model is in use and it is necessary to heat the substance flowing inside the inner tube 2, the staff energizes the heating wire 3. When the heating wire 3 is energized, it can generate heat, thereby heating the substance flowing inside the inner tube 2. When the heating wire 3 generates heat, the temperature of the outer tube 1 will also gradually increase. When the temperature of the outer tube 1 increases, the temperature of the evaporation liquid 42 in the fixed seat 41 will also increase. When the temperature rises to the boiling point of the evaporation liquid 42, the evaporation liquid 42 will evaporate and vaporize, and push the sliding plug 43 to move. When the sliding plug 43 moves, it can push the gas in the fixed seat 41, so that the gas passes through the air guide cover 44 and blows towards the facing rotating part 53, causing the rotating part 53 to rotate. When the rotating part 53 in the fixed seat 41 rotates, it can drive the rotating shaft 52 to rotate, so that the rotating part 53 in the air suction seat 51 also rotates. When the rotating part 53 in the air suction seat 51 rotates, it can perform an air extraction action and extract the gas between the outer tube 1 and the inner tube 2. When the gas between the outer tube 1 and the inner tube 2 is extracted, the thermal conductivity of the area between the outer tube 1 and the inner tube 2 will decrease, which can reduce the heat loss during the heating process of the inner tube 2, enable the inner tube 2 to quickly heat up, and improve the heating speed of the inner tube 2.

[0025] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
