Description

TECHNICAL FIELD

[0001] The utility model belongs to chemical fiber cotton production technical field, concretely relates to a chemical fiber cotton hot baking device. BACKGROUND

[0002] In the production process of chemical fiber cotton, hot baking is a crucial process, which aims to remove moisture in chemical fiber cotton and improve the quality of chemical fiber cotton to meet the requirements of subsequent production processes. As the key equipment for realizing this process, the performance of the chemical fiber cotton hot baking device directly affects the production efficiency and quality of chemical fiber cotton.

[0003] At present, the chemical fiber cotton hot baking device widely used in the market has exposed many problems in actual operation. First of all, when the device is maintained, personnel need to repair as soon as possible to avoid long downtime and delay production. However, to reduce heat transfer and improve the stability of internal temperature, the hot baking oven is provided with a heat preservation layer outside the box to achieve the purpose of energy saving. This results in that it is difficult for the heat of the box wall to dissipate quickly after the hot baking device stops running, causing the box wall to be in a high temperature state for a long time. According to statistics, the accident rate of high-temperature scalding of maintenance personnel during equipment downtime maintenance reaches 0.3‰ every year. This not only poses a threat to the safety of maintenance personnel, but also brings unnecessary economic losses and legal risks to the enterprise. At the same time, due to slow heat dissipation, maintenance and repair need to be waited for a long time after the equipment stops running, which makes the downtime too long. According to production data statistics, the downtime accounts for 8% of the entire production time, which seriously affects the production efficiency and increases the production cost.

[0004] In addition, the existing chemical fiber cotton hot baking device is also prone to static electricity during hot baking. Chemical fiber cotton is a high polymer material, which is prone to static electricity during hot baking due to frequent friction with internal components of the device. High static electricity inside the chemical fiber cotton can attract dust and other impurities during subsequent conveying and processes, affecting the quality of the chemical fiber cotton; it can also cause electrostatic discharge and produce electric sparks, posing a serious safety hazard to chemical fiber cotton production. Once a fire or explosion occurs, the consequences are unpredictable. In summary, the existing chemical fiber cotton hot baking device has obvious deficiencies in heat dissipation, static electricity and other aspects. The utility model proposes a chemical fiber cotton hot baking device to solve the above problems and improve the safety, efficiency and quality of chemical fiber cotton production.

[0005] No effective solution has been proposed for the problems in the related art. UTILITY MODEL CONTENTS

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figs. 1-2 This utility model provides the following technical solution: a chemical fiber cotton heat drying device, including a heat drying chamber 1, an insulation layer provided on the outside of the heat drying chamber 1, the insulation layer including a fixing frame 2, the fixing frame 2 being installed on the outside of the heat drying chamber 1, first door panels 3 being installed on both sides of the fixing frame 2, and insulation cotton 4 being adhered inside the fixing frame 2 and the first door panels 3, a second door panel 5 being installed on the heat drying chamber 1 corresponding to the first door panel 3, and a heating component and a temperature monitoring component being installed on the top of the heat drying chamber 1, the heating component including a mounting frame 6, and the mounting frame 6 containing... The oven is equipped with evenly distributed electric heating tubes 7. A mounting frame 6 is fixed to the top wall inside the oven body 1. An inspection port 8 is located on the top wall of the oven body 1 at the mounting frame 6. A cover plate 9 is installed at the inspection port 8, and an air inlet 10 is located at the center of the cover plate 9. An air inlet fan 11 is installed on top of the air inlet 10. Both ends of the oven body 1 have inlets and outlets 12, and ionizers 13 are installed at the inlets and outlets 12. In this embodiment, opening the first door panel 3 during shutdown maintenance allows for rapid dissipation of heat from the oven wall, reducing the duration of high temperatures after equipment shutdown. This reduces the risk of burns to maintenance personnel, ensures personal safety, shortens equipment downtime for maintenance, improves production efficiency, and reduces production costs. Furthermore, the ionizers 3 installed at the inlets and outlets 10 neutralize static electricity on the surface of the synthetic fiber cotton, preventing static electricity from attracting dust and other impurities, thereby improving production quality.

[0022] In order to ensure the continuous conveying of chemical fiber cotton, in this embodiment, as a preferred technical solution of the present invention, a chain conveyor 14 is installed inside the hot drying oven 1, and the chain conveyor 14 passes through two inlets and outlets 12.

[0023] To facilitate the disassembly and assembly of the cover plate 9, in this embodiment, as a preferred technical solution of the present invention, the inspection port 8 and the cover plate 9 are connected by a closing mechanism.

[0024] In order to facilitate opening and closing the first door panel 3, in this embodiment, as a preferred technical solution of the present invention, one side of the first door panel 3 and the fixed frame 2 are movably connected by a hinge, and a handle 15 is installed on the other side of the first door panel 3.

[0025] In order to facilitate air circulation inside the chamber and ensure circulation, in this embodiment, as a preferred technical solution of the present invention, air outlets 16 are provided on both sides of the bottom of the hot drying chamber 1, and an air outlet fan 17 is installed at the air outlet 16.

[0026] To facilitate automatic control of the internal hot air temperature, in this embodiment, as a preferred technical solution of the present invention, the temperature monitoring component includes a temperature sensor 18 and a temperature controller 19, wherein the temperature controller 19 is electrically connected to the temperature sensor 18 and the electric heating tube 7 respectively.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, during use, the temperature controller 19 is activated, and the target temperature inside the heat drying oven 1 is set. The temperature controller 19 will automatically control the working state of the electric heating tube 7 according to the set temperature, thereby achieving precise control of the temperature inside the heat drying oven 1. At the same time, during operation, the temperature sensor 18 detects the internal temperature of the oven. When the temperature is too high or too low, the temperature sensor 18 converts the temperature information into an electrical signal and outputs it to the temperature controller 19, which then controls the temperature of the electric heating tube 7. The air intake fan 11 is activated, and flowing air is sent into the heat drying oven 1 through the air inlet 10. After being heated by the electric heating tube 7, the hot air is delivered to the surface of the chemical fiber cotton. The process involves heat drying, which simultaneously promotes air circulation within the heat drying chamber 1, resulting in a more uniform temperature distribution. The chain conveyor 14 is then activated, and the synthetic fiber cotton to be heat-dried is placed on it. The cotton is then conveyed through the inlet and outlet 12 of the heat drying chamber 1, entering the chamber for heat drying. The ionizer 13 is then activated; the ionizing air generated by the ionizer 13 effectively neutralizes the static electricity generated during the heat drying process, preventing static electricity from affecting the quality of the cotton and production safety.

[0028] During maintenance, first stop the chain conveyor 14 and convey all the dried chemical fiber cotton out of the drying chamber 1. Turn off the power to the electric heating tube 7 to stop heating. At this time, the temperature inside the drying chamber 1 will begin to gradually decrease. Continue running the inlet fan 11 and outlet fan 17 for a period of time to accelerate air circulation inside the drying chamber 1. At the same time, open the first door panel 3 to allow the surface of the chamber and the electric heating tube 7 to directly contact the outside air, promoting rapid heat dissipation from the inside of the chamber, shortening the cooling time after equipment shutdown, and reducing the risk of burns to maintenance personnel. When the temperature inside the drying chamber 1 drops to a safe temperature, turn off the outlet fan 17, and finally disconnect the main power supply to the drying device. Then, open the second door panel 5 and the cover plate 9 for inspection.
