[0002] The purpose of pre-oxidation is to transform the linear macromolecular chain of PAN raw fiber into a heat-resistant ladder-shaped structure after pre-oxidation treatment, which is non-melting and non-flammable, and can withstand high-temperature carbonization while maintaining the fiber morphology. The key equipment to achieve this transformation is the pre-oxidation furnace. The pre-oxidation furnace is an industrial furnace mainly used in the heat treatment process of polymer materials to improve their antioxidant properties.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In this embodiment, a pre-oxidation furnace with a cooling function includes a furnace body 1 and shock-absorbing feet 2, the number of the shock-absorbing feet 2 is not less than two and is fixed to the lower surface of the furnace body 1, and a cooling mechanism 3 is arranged on the upper side of the furnace body 1. The cooling mechanism 3 includes an atomizing component 31 for cooling the furnace body 1 and a cooling component 32 for cooling atomized water;

[0021] Among them, the atomization assembly 31 includes a water tank 311, a water pump 312, a water suction pipe 313, a connecting pipe 314, a rotating rod 315, an atomization ring a316, an atomization ring b317 and an atomization ring c318. The water tank 311 is fixed to the upper surface of the furnace body 1. The water pump 312 is located on the left side of the water tank 311 and is fixed to the upper surface of the furnace body 1. One end of the water suction pipe 313 is connected to the water tank 311, and the other end is connected to the water inlet end of the water pump 312. The connecting pipe 314 is connected to the water outlet end of the water pump 312, and the other end is rotatably connected to the top end of the rotating rod 315 through a sealed bearing. The rotating rod 315 is rotatably connected to the water tank 311 through a bearing, one end penetrates and extends to the upper side of the water tank 311, and the other end penetrates and extends into the furnace body 1. The atomization ring a316, the atomization ring b317 and the atomization ring c318 are located in the same horizontal plane and are concentrically distributed.

[0022] It should be noted that the design of the atomization assembly 31 takes cooling efficiency and uniformity into consideration, and achieves efficient atomization effect through multiple layers of concentrically distributed atomization rings and a rotating rod 315, which helps to improve the working performance and product quality of the pre-oxidation furnace.

[0023] Furthermore, the shapes of the atomizing ring a316, the atomizing ring b317 and the atomizing ring c318 are all circular rings, and the outer diameters decrease at equal intervals, and the atomizing ring a316, the atomizing ring b317 and the atomizing ring c318 are connected by a support tube a.

[0024] It should be noted that the three atomizing rings are all in a circular shape, which helps to achieve a 360-degree atomization effect and ensure that all parts of the furnace can evenly receive the cooling effect of the atomized water.

[0025] At the same time, the outer diameter of the atomization ring decreases in order of size. This design allows atomization rings of different sizes to cover different areas, thereby achieving a more detailed and graded atomization effect.

[0026] Furthermore, the inner diameter of the atomizing ring c318 is larger than the outer diameter of the rotating rod 315. The rotating rod 315 is a round rod with a hollow interior and a missing top end. A supporting tube b is connected between the rotating rod 315 and the atomizing ring c318.

[0027] It should be noted that the rotation of the rotating rod 315 will drive the atomizing ring to produce a dynamic atomizing effect, increase the atomizing area, and improve the cooling efficiency.

[0028] Furthermore, a water inlet pipe is connected to the top of the water tank 311 , and the water inlet pipe is connected to an external water source. A temperature and humidity sensor is arranged in the furnace body 1 .

[0029] It should be noted that the water inlet pipe at the top of the water tank 311 is connected to the external water source to ensure that the water tank 311 can continuously obtain water and maintain the continuous operation of the atomization cooling system. The temperature and humidity sensors installed in the furnace body 1 can monitor the temperature and humidity conditions in the furnace in real time and provide data support for the automatic control system.

[0030] Furthermore, a rectangular opening is formed by the missing back of the water tank 311 , and the cooling assembly 32 includes a cooling fin 321 fixed in the opening, wherein the cooling fin 321 includes a heat absorbing end and a heat releasing end, and faces the inner and outer sides of the water tank 311 respectively.

[0031] It should be noted that the addition of the cooling fins 321 significantly improves the cooling efficiency of the water in the water tank 311. The cooling fins 321 absorb the heat energy in the water tank 311 through their heat absorbing ends, thereby reducing the water temperature.

[0032] Furthermore, the cooling assembly 32 also includes two rotating blades 322 fixed on the outside of the rotating rod 315. A motor 323 is fixed on the right side of the upper surface of the water tank 311. The output shaft of the motor 323 passes through and extends into the water tank 311, and is connected to the rotating rod 315 through a belt drive.

[0033] Furthermore, the lower surfaces of the atomizing ring a316, the atomizing ring b317 and the atomizing ring c318 are connected to a plurality of atomizing nozzles 319 distributed at equal intervals, and the atomizing nozzles 319 on the atomizing ring a316, the atomizing ring b317 and the atomizing ring c318 decrease in equal amounts.

[0034] It should be noted that three atomizing rings of different sizes provide a multi-layer atomizing effect, increase the atomizing area, and help improve the cooling efficiency. The atomizing nozzles 319 are evenly distributed on the lower surface of each atomizing ring, which helps to achieve a uniform atomizing effect and ensure that all areas in the furnace can obtain effective cooling.

[0035] The working principle of the above embodiment is as follows: under the action of the water pump 312, the water in the water tank 311 is pumped out through the water pumping pipe 313, and at this time, the water will enter the rotating rod 315 through the water pumping pipe 313 and the connecting pipe 314, and at this time, the water will enter the atomizing ring a316, the atomizing ring b317 and the atomizing ring c318 through the rotating rod 315, the supporting pipe a and the supporting pipe b, and will be sprayed out through the atomizing nozzle 319 distributed in a ring shape on the upper side thereof, and under the operation of the motor 323, its output shaft will rotate with the rotating rod 315 through the belt, and will further rotate with the atomizing ring through the supporting pipe a and the supporting pipe b. a316, atomizing ring b317 and atomizing ring c318 rotate to make the atomized water more evenly distributed in the furnace body 1, thereby improving the cooling effect. In order to further improve the cooling effect in the furnace body 1, a cooling plate 321 is installed in the water tank 311. At the heat-absorbing end of the cooling plate, heat is absorbed, thereby producing a cooling effect; at the heat-releasing end, heat is released and needs to be discharged. At the same time, when the motor 323 drives the rotating rod 315 to rotate, the rotating blades 322 are stirred in the water to cool the water, thereby further improving the atomization cooling effect.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
