Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying device technology, specifically a drying device for drying painted parts. Background Technology
[0002] In modern manufacturing, painted parts serve as a crucial means of enhancing and protecting product appearance, making the drying process essential. Traditional painted parts drying equipment typically places the painted parts in a drying oven after painting, using heat to rapidly cure the paint. However, the internal pressure of the drying oven gradually increases during the drying process, necessitating depressurization before opening the oven door. Furthermore, the gases generated during drying often contain harmful substances such as volatile organic compounds (VOCs). Direct release into the atmosphere not only pollutes the environment but may also pose a threat to human health. While some drying devices on the market have gas emission capabilities, they often lack effective treatment of harmful substances in the emitted gases, resulting in poor environmental performance. Therefore, we propose a drying device for painted parts. Utility Model Content
[0003] The purpose of this invention is to provide a drying device for drying painted parts, which solves the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a drying device for drying painted parts, comprising a drying chamber, a support column fixedly installed at the bottom of the inner wall of the drying chamber, a drying rack fixedly installed at the top of the support column, heaters fixedly installed on both sides of the inner wall of the drying chamber, a filter box fixedly installed near one side of the top of the drying chamber, an air guide pipe connected between one side of the filter box and the top of the drying chamber, a physical adsorption layer disposed inside the filter box, the physical adsorption layer movably penetrating the top of the filter box, a cover plate fixedly installed at the top of the physical adsorption layer, a purification chamber fixedly installed near the other side of the top of the drying chamber, a guide plate fixedly installed on one side of the inner wall of the purification chamber, an air pump disposed between the purification chamber and the filter box, an air outlet pipe connected to one side of the purification chamber at the output end of the air pump, and an air intake pipe connected to the other side of the filter box at the input end of the air pump.
[0005] Preferably, a fixed frame is fixedly installed at the top of the purification chamber, a motor is fixedly installed at the top of the fixed frame, and a rotating shaft is fixedly installed at the output end of the motor. The rotating shaft movably passes through the top of the fixed frame and the guide plate, and the rotating shaft is rotatably connected to the fixed frame through a bearing. A stirring plate is provided below the guide plate and is fixedly installed on the outer wall of the rotating shaft. When gas enters the purification chamber, the motor starts and drives the rotating shaft to rotate, which in turn drives the stirring plate to rotate, causing the stirring plate to agitate the purification liquid, increasing the flow of the purification liquid, allowing the gas to fully react with the purification liquid, and improving the purification quality and efficiency.
[0006] Preferably, sealing rings are fixedly installed at both the top and bottom of the guide plate. The sealing rings are tightly fitted onto the outer wall of the rotating shaft. By setting the sealing rings, the rotating shaft and the guide plate can be sealed, thereby improving the sealing performance between the rotating shaft and the guide plate.
[0007] Preferably, the purification box contains a purification liquid, and the front of the drying box is hinged with a door. The purification liquid can be a solution of a strong oxidant such as ozone or potassium permanganate.
[0008] Preferably, a fixing block is fixedly installed on the outer wall of the filter box, and a shaft hole is opened on the fixing block. A connecting shaft movably passes through the shaft hole. A torsion spring is fixedly connected between the outer wall of the connecting shaft and the inner wall of the shaft hole. A baffle is fixedly installed at the bottom end of the connecting shaft, and a limiting plate is fixedly installed at the top end of the connecting shaft. The limiting plate is engaged with the top end of the cover plate. By rotating the limiting plate, the limiting plate drives the connecting shaft to torsion spring, causing the limiting plate to rotate 30°, so that the limiting plate no longer limits the cover plate. At this time, the cover plate can be pulled upward, causing the cover plate to pull the physical adsorption layer away from the filter box, thereby allowing the physical adsorption layer to be disassembled and replaced. The physical adsorption layer can be a multi-layer structure, such as an activated carbon adsorption layer, a glass fiber cotton adsorption layer, and a filter cotton adsorption layer.
[0009] Preferably, a pad is fixedly installed at the bottom end of the limiting plate, and the pad is in close contact with the top surface of the cover plate. The pad is made of wear-resistant rubber. By setting the pad, the connection between the limiting plate and the cover plate can be increased, and the stability of the limiting plate during use can be improved.
[0010] This utility model provides a drying device for drying painted parts. This drying device for drying painted parts has the following beneficial effects:
[0011] (1) The drying device for drying painted parts can quickly depressurize the inside of the drying box after the painted parts are dried. During the process of venting the gas inside the drying box, harmful substances in the gas can be removed by physical and chemical methods at the same time, so as to avoid the exhaust gas containing more harmful substances and polluting the air, and improve the environmental protection of the device during use.
[0012] (2) The drying device for drying painted parts, by setting up a motor, a rotating shaft and a stirring plate together, can make the stirring plate stir the purification liquid, increase the flow of the purification liquid, and allow the gas to fully react with the purification liquid, thereby improving the purification quality and efficiency. By setting up a guide plate, the gas can be guided to a certain extent, increasing the contact time between the gas and the purification liquid, and further improving the purification quality of the gas. The structure is simple and the practicality is strong. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a drying device for drying painted parts, including a drying box 1, a support column 3 fixedly installed at the bottom of the inner wall of the drying box 1, a drying rack 2 fixedly installed at the top of the support column 3, heaters 4 fixedly installed on both sides of the inner wall of the drying box 1, a filter box 6 fixedly installed near one side of the top of the drying box 1, an air guide pipe 5 connected between one side of the filter box 6 and the top of the drying box 1, a physical adsorption layer 7 disposed inside the filter box 6, the physical adsorption layer 7 movably penetrating the top of the filter box 6, a cover plate 8 fixedly installed at the top of the physical adsorption layer 7, a purification box 12 fixedly installed near the other side of the top of the drying box 1, a guide plate 13 fixedly installed on one side of the inner wall of the purification box 12, an air pump 10 disposed between the purification box 12 and the filter box 6, an air outlet pipe 11 connected to one side of the purification box 12 at the output end of the air pump 10, and an air intake pipe 9 connected to the other side of the filter box 6 at the input end of the air pump 10.
[0023] Specifically, in the above technical solution, the drying device for drying painted parts is used by placing the painted parts to be dried on the drying rack 2, then closing the chamber door 26, turning on the heater 4, and continuously drying the painted parts. After the painted parts are dried, the air pump 10 is turned on first, so that the air pump 10 draws in the high-pressure gas generated in the drying chamber 1 through the suction pipe 9, the filter box 6, and the air guide pipe 5. When the gas passes through the filter box 6, the physical adsorption layer 7 adsorbs and filters the harmful substances in the gas. The gas that has passed through the physical adsorption layer 7 is then transported to the purification chamber 12 through the exhaust pipe 11, so that the gas comes into contact with the purification liquid in the purification chamber 12. The purification liquid further reacts with and removes harmful substances in the gas. When the gas enters the purification chamber 12, the motor 15 starts and drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the stirring plate 17 to rotate, which stirs the purification liquid and increases its flow. This allows the gas to fully react with the purification liquid, improving the purification quality and efficiency. Through the above structure, the pressure inside the drying chamber 1 can be quickly released after the painted parts are dried. During the process of venting the gas inside the drying chamber 1, harmful substances in the gas can be removed simultaneously using physical and chemical methods, avoiding the presence of a large amount of harmful substances in the vented gas, thus preventing air pollution and improving the environmental friendliness of the device during use.
[0024] Furthermore, a fixed frame 14 is fixedly installed at the top of the purification box 12, a motor 15 is fixedly installed at the top of the fixed frame 14, a rotating shaft 16 is fixedly installed at the output end of the motor 15, the rotating shaft 16 movably passes through the top of the fixed frame 14 and the guide plate 13, and the rotating shaft 16 is rotatably connected to the fixed frame 14 through a bearing, and a stirring plate 17 is provided below the guide plate 13, and the stirring plate 17 is fixedly installed on the outer wall of the rotating shaft 16;
[0025] When the gas enters the purification chamber 12, the motor 15 starts and drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the stirring plate 17 to rotate, which stirs the purification liquid, increases the flow of the purification liquid, and allows the gas to fully react with the purification liquid, thereby improving the purification quality and efficiency.
[0026] Furthermore, sealing rings 18 are fixedly installed at both the top and bottom of the guide plate 13, and the sealing rings 18 are tightly fitted onto the outer wall of the rotating shaft 16.
[0027] By setting a sealing ring 18, the shaft 16 and the guide plate 13 can be sealed, thereby improving the sealing performance between the shaft 16 and the guide plate 13.
[0028] Furthermore, the purification box 12 is filled with purification liquid, and the front of the drying box 1 is hinged with a door 26.
[0029] The purification solution can be a solution of strong oxidants such as ozone or potassium permanganate.
[0030] Furthermore, a fixing block 19 is fixedly installed on the outer wall of the filter box 6. A shaft hole 21 is opened on the fixing block 19. A connecting shaft 20 is movably passed through the shaft hole 21. A torsion spring 22 is fixedly connected between the outer wall of the connecting shaft 20 and the inner wall of the shaft hole 21. A baffle 23 is fixedly installed at the bottom of the connecting shaft 20. A limiting plate 24 is fixedly installed at the top of the connecting shaft 20. The limiting plate 24 is snapped into the top of the cover plate 8.
[0031] Specifically, by rotating the limiting plate 24, the limiting plate 24 drives the connecting shaft 20 to twist the torsion spring 22, causing the limiting plate 24 to rotate 90°, so that the limiting plate 24 no longer limits the cover plate 8. At this time, the cover plate 8 can be pulled upward, causing the cover plate 8 to pull the physical adsorption layer 7 away from the filter box 6, thereby allowing the physical adsorption layer 7 to be disassembled and replaced. The physical adsorption layer 7 can be a multi-layer structure, and can adopt activated carbon adsorption layer, glass fiber cotton adsorption layer and filter cotton adsorption layer, etc.
[0032] Furthermore, a pad 25 is fixedly installed at the bottom of the limiting plate 24. The pad 25 is in close contact with the top surface of the cover plate 8. The pad 25 is made of wear-resistant rubber.
[0033] By setting the pad 25, the connection between the limiting plate 24 and the cover plate can be strengthened, and the stability of the limiting plate 24 during use can be improved.
