Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying oven technology, specifically a drying device for automotive parts with a preheating recovery structure. Background Technology
[0002] In the production and processing of automotive parts, drying is a crucial step in ensuring part quality. Its core function is to remove surface and internal moisture from parts to prevent problems such as rust, coating peeling, or failure of precision components during subsequent assembly. Currently, the most widely used drying equipment in the industry is the hot air drying device. This type of device typically uses a heater to heat air into high-temperature hot air, which is then sent into the drying chamber by a fan to exchange heat with the automotive parts to be dried. The heat of the hot air evaporates the moisture in the parts, which is then discharged with the exhaust gas, thus completing the drying process.
[0003] However, most existing hot air-type automotive parts drying devices on the market suffer from low energy efficiency. Their core flaw lies in the fact that the device only achieves drying by continuously outputting heat through the heater, without effectively recovering and reusing the high-temperature exhaust gas (containing a large amount of waste heat) discharged during the drying process. Often, this part of the high-temperature exhaust gas is directly discharged into the external environment, resulting in complete waste of waste heat. In order to maintain the set temperature and drying effect in the drying chamber, the heater must always operate at high power to compensate for heat loss. Even in the later stages of drying when the moisture evaporation of the parts decreases and the heat demand decreases, the heater still needs to continue to consume a large amount of energy, ultimately resulting in a high overall energy consumption level of the device. This not only increases the production and operating costs of enterprises, but also goes against the current development trend of energy conservation, emission reduction and green production in the industrial field.
[0004] Therefore, this utility model provides an automotive parts drying device with a preheating recovery structure. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an automotive parts drying device with a preheating and recovery structure to solve the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for automotive parts with a preheating and recovery structure, comprising a support box and a conveying mechanism. Both sides of the support box have clearance through holes to allow space for the conveying mechanism. The conveying mechanism extends through two of these clearance through holes. A hot dryer is installed on one side of the support box, and an air inlet pipe is provided on one side of the hot dryer. One end of the air inlet pipe penetrates the side wall of the support box, and a multi-bend heat absorption guide pipe is installed at one end of the air inlet pipe. An air inlet hood is installed at one end of the multi-bend heat absorption guide pipe, located outside the support box. An exhaust pipe is installed on one side of the hot dryer, and the exhaust pipe has several discharge holes.
[0007] Preferably, a plurality of exhaust fans are installed at the top of the support box, and the plurality of exhaust fans are all located directly above the conveying mechanism.
[0008] Preferably, a flow guide box is installed on the outside of the exhaust pipe, the flow guide box is installed on the inner side of the bottom of the support box, and a plurality of flow guide plates are installed on the inner side of the top opening of the flow guide box, the flow guide plates are aligned with the direction of the conveying mechanism.
[0009] Preferably, two support rods are installed on the inner wall of the support box, and the multi-bend heat absorption and diversion pipe rests on the two support rods.
[0010] Preferably, both sides of the support box are slidably connected to lifting plates, and the two lifting plates correspond to the positions of the corresponding clearance through holes.
[0011] Preferably, a fixed plate is provided above the two lifting plates, two electric telescopic rods are installed at the bottom of the fixed plate, two connecting rods are installed on the side wall of the lifting plates, and the output end of the electric telescopic rod is installed at the top of the corresponding connecting rod.
[0012] Compared with the prior art, the present invention has the following advantages: As the waste gas containing residual heat generated during the drying process flows upward, it is carried by the airflow continuously drawn in by the multi-bend heat-absorbing guide pipe. Part of the waste heat is absorbed by the preheating air inside the multi-bend heat-absorbing guide pipe, achieving secondary heat utilization. Through this structure, the multi-bend heat-absorbing guide pipe preheats the drawn-in external air, reducing the energy consumption required for the hot dryer to directly heat cold air. Simultaneously, the waste heat generated during drying is effectively recovered for air preheating, solving the problems of existing devices that directly discharge high-temperature waste gas leading to waste heat and continuous high-energy-consumption operation of the heater. This reduces enterprise operating costs and aligns with the green production trend of energy conservation and emission reduction. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0016] Please see Figure 1-5 A drying device for automotive parts with a preheating and recovery structure includes a support box 1 and a conveying mechanism 2. Both sides of the support box 1 are provided with clearance through holes 12 to allow space for the conveying mechanism 2. The conveying mechanism 2 extends out through the two clearance through holes 12. A hot dryer 3 is installed on one side of the support box 1. An air inlet pipe 31 is provided on one side of the hot dryer 3. One end of the air inlet pipe 31 penetrates the side wall of the support box 1. A multi-bend heat absorption guide pipe 32 is installed on one end of the air inlet pipe 31. An air inlet hood 321 located outside the support box 1 is installed on one end of the multi-bend heat absorption guide pipe 32. An exhaust pipe 33 is installed on one side of the hot dryer 3. Several discharge holes 331 are provided on the exhaust pipe 33.
[0017] Specifically, after the hot dryer 3 starts, the suction force is transferred to the multi-bend heat absorption guide pipe 32 through the air inlet pipe 31. The multi-bend heat absorption guide pipe 32 draws air from outside the support box 1 through the air inlet hood 321. After the outside air enters the multi-bend heat absorption guide pipe 32, it comes into full contact with the high-temperature waste heat retained in the pipe during the process of flowing through the multi-bend structure to achieve preheating. At the same time, the high-temperature hot air generated by the hot dryer 3 is transported to the bottom of the conveying mechanism 2 through the exhaust pipe 33, and then sprayed from bottom to top through several discharge holes 331 on the exhaust pipe 33. It acts on the automotive parts on the conveying mechanism 2. Because the transmission belt is a breathable mesh, the hot air can penetrate the transmission belt and contact the parts in all directions. The heat is used to evaporate the moisture in the parts to complete the drying. When the waste gas containing waste heat generated during the drying process flows upward, it is driven by the airflow continuously drawn by the multi-bend heat absorption guide pipe 32. Some of the waste heat is absorbed by the air that is being preheated in the multi-bend heat absorption guide pipe 32, realizing the secondary utilization of heat. With this structure, the multi-bend heat absorption and guide pipe 32 preheats the intake external air, reducing the energy consumption required for the hot dryer 3 to directly heat the cold air. At the same time, the waste heat generated during drying is effectively recovered for air preheating, solving the problems of waste heat waste caused by direct emission of high-temperature exhaust gas in existing devices and continuous high energy consumption of heaters. This not only reduces the company's operating costs but also conforms to the green production trend of energy conservation and emission reduction.
[0018] In one embodiment of this utility model, such as Figures 1-5 As shown, several exhaust fans 11 are installed at the top of the support box 1, and all of the exhaust fans 11 are located directly above the conveying mechanism 2.
[0019] Specifically, when the hot air blows hot air from bottom to top through the exhaust pipe 33 and the discharge hole 331, it penetrates the breathable mesh transmission belt and acts on the accessories, causing the moisture to evaporate and forming high-temperature and high-humidity exhaust gas containing residual heat. Then, the exhaust fan 11 at the top of the support box 1 starts, generating an upward suction force to quickly draw the high-temperature and high-humidity exhaust gas gathered directly above the transmission mechanism 2 away from the inside of the support box 1. At the same time, the suction effect of the exhaust fan 11 will form a stable airflow circulation inside the support box 1, causing the hot air that has not been in full contact with the accessories to continue to flow upward, conduct efficient heat exchange with the accessories, and avoid the high-temperature and high-humidity exhaust gas from being locally stagnant inside the box.
[0020] In one embodiment of this utility model, such as Figures 1-5 As shown, a flow guide box 4 is installed on the outside of the exhaust pipe 33. The flow guide box 4 is installed on the inner side of the bottom of the support box 1. Several flow guide plates 41 are installed on the inner side of the top opening of the flow guide box 4. The flow guide plates 41 are aligned with the direction of the conveying mechanism 2.
[0021] Specifically, when the high-temperature hot air generated by the hot dryer 3 is transported through the exhaust pipe 33, the guide box 4 on the outside of the exhaust pipe 33 forms a converging constraint on the hot air, preventing the hot air from spreading randomly on the inner side of the bottom of the support box 1; then, the hot air is discharged through the discharge hole 331 on the exhaust pipe 33 and enters the interior of the guide box 4, and is then guided by several guide plates 41 on the inner side of the top opening of the guide box 4, forming a uniform airflow distributed along the conveying direction of the conveying mechanism 2, which penetrates vertically upward through the breathable mesh transmission belt of the conveying mechanism 2, and acts on the automotive parts on the conveying mechanism 2, providing stable and uniform heat for drying the parts.
[0022] In one embodiment of this utility model, such as Figures 1-5 As shown, two support rods 13 are installed on the inner wall of the support box 1, and the multi-bend heat absorption and diversion pipe 32 rests on the two support rods 13.
[0023] Specifically, the two support rods 13 on the inner wall of the support box 1 provide a stable support for the multi-bend heat absorption guide pipe 32, enabling the multi-bend heat absorption guide pipe 32 to be accurately and stably positioned at a preset position directly above the conveying mechanism 2. At the same time, the way the support rods 13 support the multi-bend heat absorption guide pipe 32 avoids a direct rigid connection between the multi-bend heat absorption guide pipe 32 and the inner wall of the support box 1, reducing the impact of vibration of the heat dryer 3 and airflow on the position of the multi-bend heat absorption guide pipe 32 during operation, ensuring that it always maintains the integrity and functionality of the multi-bend structure, thereby stably realizing the core function of drawing air from outside the support box 1 through the air inlet hood 321 and completing air preheating inside the pipe.
[0024] In one embodiment of this utility model, such as Figures 1-5 As shown, lifting plates 5 are slidably connected to both sides of the support box 1, and the two lifting plates 5 correspond to the positions of the corresponding clearance through holes 12.
[0025] Specifically, before the device is put into operation, the gap between the lifting plates 5 and the conveying mechanism 2 is changed by sliding the lifting plates 5 on both sides of the support box 1 according to the height of the automotive parts to be dried on the conveying mechanism 2. When the parts are high, the lifting plates 5 are slid upward to increase the gap, ensuring that the parts can pass smoothly through the clearance hole 12. When the parts are low, the lifting plates 5 are slid downward to decrease the gap, so that the lifting plates 5, the conveying mechanism 2 and the edge of the parts form a relatively sealed structure. During the drying process, this structure can reduce the loss of high-temperature hot air inside the support box 1 from the clearance hole 12, and at the same time prevent a large amount of low-temperature air from entering the box and interfering with the drying environment.
[0026] In one embodiment of this utility model, such as Figures 1-5As shown, a fixed plate 51 is provided above the two lifting plates 5. Two electric telescopic rods 52 are installed at the bottom of the fixed plate 51. Two connecting rods 53 are installed on the side wall of the lifting plate 5. The output end of the electric telescopic rod 52 is installed at the top of the corresponding connecting rod 53.
[0027] Specifically, before the device is put into operation, based on the height of the automotive parts to be dried on the conveying mechanism 2, the electric telescopic rod 52 at the bottom of the fixed plate 51 is extended and retracted, driving the connecting rod 53 connected to its output end to move up and down, thereby driving the lifting plates 5 on both sides of the support box 1 to slide along the side wall of the box, so as to achieve precise adjustment of the gap between the lifting plate 5 and the conveying mechanism 2; when the height of the parts is high, the electric telescopic rod 52 extends, driving the lifting plate 5 to move up through the connecting rod 53 to increase the gap, ensuring that the parts can pass smoothly through the clearance hole 12; when the height of the parts is low, the electric telescopic rod 52 shortens, driving the lifting plate 5 to move down through the connecting rod 53 to reduce the gap, forming a relatively sealed structure, reducing the leakage of high-temperature hot air inside the support box 1 from the clearance hole 12 and the intrusion of external cold air during the drying process.
[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0029] Working principle: When the device is working, after the hot dryer 3 starts, the suction is transmitted to the multi-bend heat absorption guide pipe 32 through the air inlet pipe 31. The multi-bend heat absorption guide pipe 32 is stably supported above the conveying mechanism 2 by two support rods 13 on the inner wall of the support box 1. The air outside the support box 1 is drawn in through the air inlet hood 321. The air is preheated by contacting the retained high-temperature residual heat in the multi-bend structure inside the pipe. At the same time, the high-temperature hot air generated by the hot dryer 3 is transported through the exhaust pipe 33. The guide box 4 on the outside of the exhaust pipe 33 gathers the hot air and guides it through the guide plate 41 on the top of the guide box 4, which is aligned with the direction of the conveying mechanism 2. This forms a uniform airflow that passes through the breathable mesh conveyor belt from bottom to top through the discharge hole 331 and acts on the accessories to evaporate the moisture. The waste gas containing residual heat generated during drying flows upward, part of which is absorbed by the preheated air in the multi-bend heat absorption guide pipe 32, and the remainder is drawn away by the exhaust fan 11 at the top of the support box 1 to form a stable airflow circulation; the lifting plates 5 on both sides of the support box 1 are raised and lowered by the electric telescopic rod 52 below the fixed plate 51, which drives the connecting rod 53 to reduce heat leakage according to the height adjustment of the accessories and the clearance of the through hole 12. The whole system reduces the energy consumption of the hot dryer 3 through waste heat recovery, airflow optimization and sealing adjustment, solving the problems of waste heat waste and high energy consumption in existing devices.
