Description

TECHNICAL FIELD

[0001] The utility model belongs to shoe double -way heating equipment technical field, specifically is shoe double -way heating equipment's double -layer heat radiation cavity structure. BACKGROUND

[0002] In the footwear production and manufacturing process, heating and shaping, drying and other treatments of shoe materials are key links, which directly affect the quality and performance of shoes. The shoe heating equipment uses heat radiation and other methods to make the shoe material reach the temperature and state required by the process. The double -layer heat radiation cavity structure can improve production efficiency and is gradually widely used in the industry.

[0003] However, the double -layer heat radiation cavity structure of the existing shoe double -way heating equipment has many problems in actual use: the inlet and outlet of the heat radiation chamber are the main channels for heat loss. Since the conveyor belt needs to drive the shoe material in and out of the chamber during production, the chamber opening cannot be completely closed, which causes the heat in the chamber to easily convect with the outside air through the inlet and outlet, resulting in a large amount of heat loss. This not only increases energy consumption and production cost, but also affects the uniformity and consistency of shoe heating due to unstable temperature in the chamber, which reduces product quality.

[0004] Therefore, the double -layer heat radiation cavity structure of the shoe double -way heating equipment is proposed to solve the above problems. INVENTION CONTENTS

[0005] To solve the problems raised in the background art, the utility model provides a double -layer heat radiation cavity structure of shoe double -way heating equipment, which has the advantages of good heat insulation, high air cleanliness, stable equipment operation, convenient maintenance and high production efficiency.

[0007] The air curtain heat insulation component comprises a horizontal pipe arranged above the inlet and outlet of the heat radiation chamber, the bottom of the horizontal pipe is provided with a long slit nozzle, one end of the horizontal pipe is provided with a pipe joint, the pipe joint is connected with a wind guide pipe, the wind guide pipe is connected with a centrifugal fan, and the centrifugal fan is arranged at the top of the heating equipment main body.

[0008] Preferably, the air suction, filtering and adsorption assembly includes a vertical pipe, an outlet pipe is connected to one side of the vertical pipe near the top, the outlet pipe is connected to the inlet of the centrifugal fan through a guide pipe, and an inlet pipe is connected to the other side of the vertical pipe near the bottom, the vertical pipe is filled with adsorption filler, and the top and bottom of the vertical pipe are respectively threadedly connected with a top cover and a bottom cover.

[0009] Preferably, a coarse filter and a fine filter are installed in the inlet pipe and the outlet pipe respectively.

[0010] Preferably, a bracket is fixedly connected to the outer side of the vertical pipe, and the bracket is connected to the heating equipment body by bolts.

[0011] Preferably, thermal insulation silicone curtains are provided at the inlet and outlet of the heat radiation chamber.

[0012] Preferably, vertical guide plates are provided on both the front and rear sides of the inlet and outlet of the heat radiation chamber, and the transverse tube is located between the vertical guide plates.

[0013] Preferably, the height of the vertical guide plate is greater than the height of the air curtain.

[0014] Preferably, the air curtain airflow at the inlet of the heat radiation chamber is inclined at a certain angle toward the inside of the heat radiation chamber, and the air curtain airflow at the outlet of the heat radiation chamber is inclined at a certain angle toward the outside of the heat radiation chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The heat radiation chamber of the present invention is equipped with air curtain insulation components at both the inlet and outlet. Air is ejected through the long slit-shaped nozzle at the bottom of the horizontal tube to form an air curtain, which can effectively interfere with the convection between hot air and the outside cold air, reduce the rate at which hot air is dissipated from the inlet and outlet, and reduce heat loss, thereby ensuring the temperature stability in the heat radiation chamber. This not only helps to improve the uniformity and consistency of shoe material heating and ensure the quality of shoes, but also reduces energy consumption and production costs.

[0017] 2. Before entering the wind curtain insulation component, the outside air of the utility model first passes through a coarse filter to intercept large particles of impurities, such as dust, shoe material debris, and fluff, and then passes through a vertical pipe filled with adsorption filler to absorb volatile organic compounds volatilized from shoe adhesives and coatings. Finally, it passes through a fine filter to filter out even finer particles. Multiple filtration and adsorption can effectively purify the air entering the heat radiation chamber and prevent impurities from adhering to the surface of the shoe material and affecting the quality of the shoes.

[0029] Air curtain heat insulation component 4 includes the horizontal pipe 41 set on the top of the import and export of heat radiation chamber 3, the horizontal pipe 41 is as airflow distribution channel, and the airflow delivered by the fan is uniformly distributed to the long slit nozzle 42, so that the uniformity of the air curtain is ensured, the bottom of the horizontal pipe 41 is provided with the long slit nozzle 42, the airflow in the horizontal pipe 41 is converted into a linear air curtain, the import and export cross sections of the heat radiation chamber 3 are accurately covered, the heat insulation and impurity blocking effects are optimized, one end of the horizontal pipe 41 is provided with the pipe joint 43, the horizontal pipe 41 and the air guide pipe 44 are quickly connected / detached, the airflow transmission sealing property is ensured, and maintenance is facilitated, the pipe joint 43 is connected with the air guide pipe 44, the airflow transmission path between the centrifugal fan 45 and the horizontal pipe 41 is constructed, air resistance is reduced, airflow delivery is stabilized, the air guide pipe 44 is connected with the centrifugal fan 45, a power source is provided for the formation of the air curtain, airflow circulation is driven, the required strength and angle of the air curtain are achieved, the centrifugal fan 45 is arranged at the top of the heating equipment main body 1, reasonable layout saves ground space, shortens the airflow transmission path, improves the fan efficiency, and facilitates equipment integration.

[0030] Specifically, the air suction filter adsorption component 5 includes a vertical pipe 51, which serves as a core carrier for filtration and adsorption, accommodates adsorption filler 55, and installs a filter screen to provide a closed space for air purification. An outlet pipe 52 is connected to one side of the vertical pipe 51 near the top. The outlet pipe 52 guides the purified clean air to the air guide pipe 44 and enters the wind curtain system to ensure the cleanliness of the air curtain airflow. The outlet pipe 52 is connected to the inlet of the centrifugal fan 45 through the guide pipe 53 to construct an airflow circulation path of "air suction filtration → wind curtain insulation" to ensure the cleanliness of the purified air. It is quasi-participating in the wind curtain barrier. The other side of the vertical pipe 51 is connected to the position near the bottom with an inlet pipe 54 to introduce the ambient air of the workshop, start the filtering and adsorption process, and provide the air source for the wind curtain. The vertical pipe 51 is filled with adsorption filler 55, which uses the adsorption properties of materials such as activated carbon to remove VOCs, odors and some fine pollutants in the air and purify the air. The top and bottom of the vertical pipe 51 are respectively threadedly connected with a top cover 56 and a bottom cover 57, which support quick disassembly and assembly, facilitate the replacement of the adsorption filler 55, and clean the internal dust, reducing the difficulty of operation and maintenance and downtime.

[0031] Furthermore, a coarse filter 58 and a fine filter 59 are installed in the inlet pipe 54 and the outlet pipe 52 respectively. The coarse filter 58 intercepts large particles of impurities (such as shoe scraps and fluff), and the fine filter 59 filters fine dust (such as leather polishing dust). Double filtration improves air cleanliness and protects subsequent adsorption filler 55 and the air curtain system.

[0032] Furthermore, a bracket 510 is fixedly connected to the outer side of the vertical pipe 51 to provide rigid support for the vertical pipe 51, ensuring that the suction, filtration and adsorption component 5 is firmly connected to the equipment body to avoid vibration and displacement during operation. The bracket 510 is connected to the heating equipment body 1 by bolts to achieve a modular connection between the component and the body, which is convenient for installation, debugging and later maintenance and replacement.

[0033] It is worth noting that insulating silicone curtains 6 are provided at the inlet and outlet of the heat radiation chamber 3 to assist the wind curtains in strengthening the sealing of the inlet and outlet, physically blocking heat radiation and airflow leakage, adapting to the dynamic gap of the shoe material entering and exiting, and supplementing the sealing blind spot of the wind curtain.

[0034] It is worth noting that vertical guide plates 7 are provided on both the front and rear sides of the inlet and outlet of the heat radiation chamber 3 to limit the lateral diffusion of the wind curtain airflow, force the airflow to be distributed along the inlet and outlet cross-sections, optimize the sealing and stability of the wind curtain, and improve the heat insulation and impurity barrier efficiency. The horizontal tube 41 is located between the vertical guide plates 7, so that the wind curtain airflow is concentrated in the space limited by the guide plates, thereby strengthening the sealing effect of the inlet and outlet.

[0035] It is worth mentioning that the height of the vertical guide plate 7 is greater than the height of the wind curtain, which fully covers the vertical space of the inlet and outlet, blocks the air flow from overflowing from the top, eliminates heat leakage in the gap between the wind curtain and the chamber wall, and improves the overall thermal insulation performance.

[0036] It is worth emphasizing that the air curtain airflow at the inlet of the heat radiation chamber 3 is inclined at a certain angle toward the heat radiation chamber 3, guiding the outside air to flow into the chamber, forcing the cold air to flow back, and "pushing" the overflowing hot air back into the chamber to maintain the temperature field in the chamber stable. The air curtain airflow at the outlet of the heat radiation chamber 3 is inclined at a certain angle toward the outside of the heat radiation chamber, blocking the hot air in the chamber from overflowing with the shoe materials, and preventing the outside cold air from flowing back from the outlet, thereby ensuring the thermal environment in the chamber and the heating quality of the shoe materials.

[0037] Among them, the heating equipment body 1, the conveyor belt 2, and the centrifugal fan 45 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: The shoe materials to be heated are placed on two upper and lower corresponding conveyor belts 2, and are driven by the conveyor belts 2 into two upper and lower corresponding heat radiation chambers 3 opened on the main body 1 of the heating device. The centrifugal fan 45 is started, and the outside air is sucked in through the inlet pipe 54 of the suction filter adsorption component 5. The air first passes through the coarse filter 58 in the inlet pipe 54 to filter large particles of impurities, and then enters the vertical pipe 51. After the internal adsorption filler 55 absorbs VOCs and odors, the fine filter 59 in the outlet pipe 52 further filters fine dust. The purified air The air enters the centrifugal fan 45 through the guide pipe 53, and is then sent to the horizontal pipe 41 through the air guide pipe 44 and the pipe joint 43. Finally, it is ejected from the long slit nozzle 42 at the bottom of the horizontal pipe 41 to form an air curtain. The air curtain at the inlet of the heat radiation chamber 3 is tilted toward the cavity to block the entry of cold air, and the air curtain at the outlet is tilted toward the outside of the cavity to prevent the overflow of hot air. The air curtain reduces lateral diffusion under the action of the vertical guide plate 7. At the same time, the heat-insulating silicone curtain 6 helps to enhance the sealing. The shoe material is subjected to heat radiation heating treatment in the heat radiation chamber 3 and is taken out by the conveyor belt 2 after the treatment is completed.
