Description

Technical Field

[0001] This utility model belongs to the field of coating material drying technology, and in particular relates to a drying box for drying and curing coating materials. Background Technology

[0002] A drying oven for drying and curing coating materials is a temperature-controlled heating device specifically designed for workpieces such as metal parts, plastic parts, and electronic components that have been coated with paint, coatings, adhesives, insulating layers, or other coating materials. Its core function is to provide a stable and uniform heating environment for the coating materials by precisely controlling key parameters such as the temperature inside the oven, heating time, and air circulation rate. This promotes physical or chemical changes within the coating materials—such as solvent evaporation and moisture evaporation at the physical level, and cross-linking polymerization and curing reactions at the chemical level. Ultimately, this results in a strong and stable cured coating on the workpiece surface, while ensuring that the workpiece does not deform, crack, or have an uneven coating during the drying and curing process.

[0003] However, in the operation of existing devices, the filter plates of the exhaust gas treatment device adopt a relatively complex fixing structure design with the main body of the device. This complex fixing method will cause operators to spend a lot of time disassembling the fixing components during subsequent maintenance. This not only prolongs the replacement time of the filter plates, but also increases the difficulty of operation, thus affecting the overall operating efficiency and maintenance convenience of the exhaust gas treatment device. Utility Model Content

[0004] The purpose of this utility model is to provide a drying box for drying and curing coating materials. By setting a fixing part, it solves the problem that the fixing structure design of the filter plate and the main body of the waste gas treatment device is relatively complicated. This complicated fixing method will cause the operator to spend a lot of time disassembling the fixing parts during subsequent maintenance. This not only prolongs the replacement time of the filter plate, but also increases the difficulty of operation, thereby affecting the overall operating efficiency and maintenance convenience of the waste gas treatment device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a drying box for drying and curing coating materials, comprising a drying box and further comprising: a fixing part disposed at the top of the drying box; a filter part disposed at the top of the drying box; the fixing part comprising a fixing assembly disposed at the top of the drying box; and a limiting assembly mounted on the fixing assembly; the fixing assembly comprising a filter box fixedly connected to the top of the drying box, the top of the filter box being provided with a sealing cover, and both sides of the sealing cover being fixedly connected with notched clamping plates, both of which are open The filter box is provided with a limiting groove. Rectangular frames are fixedly connected to both sides of the filter box. Notch blocks are slidably connected to both rectangular frames. Two slide rods are slidably connected to both rectangular frames. One end of each slide rod is close to the other two notch blocks. A reset component is provided on each slide rod. The two notch blocks are adapted to the two limiting grooves. The reset component includes a spring wrapped around the outer wall of the slide rods. One end of each spring is fixedly connected to the two notch blocks, and the other end of each spring is fixedly connected to the two rectangular frames.

[0007] Furthermore, the filtration section includes a filter assembly disposed at the top of the drying chamber; and a configuration component mounted on the filter assembly.

[0008] Furthermore, the limiting component includes screws fixedly connected to two notch blocks. The ends of the two screws that are far apart from each other extend outside the two rectangular frames and are slidably connected to the two rectangular frames. The outer walls of the two screws are threaded with anti-loosening nuts. Each screw is provided with a limiting component. The ends of the two anti-loosening nuts that are far apart from each other are in contact with the two rectangular frames. The limiting component includes limiting nuts that are threaded to the outer walls of the two screws. The sides of the two limiting nuts that are close to each other are in contact with the two rectangular frames. By setting screws on the notch blocks, and cooperating with the anti-loosening nuts outside the rectangular frames and the limiting nuts inside the rectangular frames, a double limiting structure is formed. The anti-loosening nuts can prevent the screws from detaching from the rectangular frames, and the limiting nuts can fix the position of the notch blocks. The double locking ensures that the notch blocks are firmly connected to the rectangular frames. The threaded engagement of the screws and nuts allows for flexible and precise position adjustment, which can adapt to different working conditions.

[0009] Furthermore, the filter assembly includes several slots formed on the inner wall of the bottom of the filter box, in which filter plates are slidably connected. Several fans are arranged on the left side of the filter box, and a sealing element is provided on the filter box. Three fans are provided. The sealing element includes a sealing groove formed on the top of the filter box, and a sealing ring is fixedly connected to the bottom of the sealing cover. The bottom of the sealing ring extends into the sealing groove and is adapted to the sealing groove. The filter plates are slidably connected through the slots on the inner wall of the bottom of the filter box, which facilitates the airflow drive of the three fans and enables multi-layer filtration of air or fluid. The slot design facilitates the quick disassembly and replacement of the filter plates. The sealing groove on the top of the filter box and the sealing ring at the bottom of the sealing cover are adapted to enhance the sealing performance of the filter box and prevent leakage of unfiltered media.

[0010] Furthermore, the configuration component includes several connecting pipes fixedly connected to the right side of the filter box. An air suction hood is fixedly connected to the top of the drying box, and the air suction hood communicates with the drying box. The right ends of the several connecting pipes are all fixedly connected to the air suction hood, and the several connecting pipes communicate with both the filter box and the air suction hood. By connecting the air suction hood of the drying box to the right side of the filter box, and with each connecting pipe communicating with both the filter box and the air suction hood, an airflow channel is constructed between the filter box and the drying box. This allows the gas in the drying box to enter the filter box for processing via the air suction hood and connecting pipes, achieving a seamless connection between directional gas delivery and filtration purification. The multiple connecting pipes enhance airflow efficiency and ensure timely gas processing.

[0011] This utility model has the following beneficial effects: 1. By setting up a fixing part, when it is necessary to replace multiple filter plates after long-term filtration, first pull the notch block outward, causing it to drive the screw to slide outside the rectangular frame to release the limiting position on the filter box notch block. During this process, the sliding rod on the notch block moves outward simultaneously, compressing the spring to store force, preparing for subsequent reset. After the notch block moves to the appropriate position, screw the limiting nut on the screw inward, and temporarily fix the notch block with the help of the rectangular frame, making it convenient for the operator to disassemble the same structure on the other side. After both fixing mechanisms are released from their limiting positions, the sealing cover can be separated from the filter box. The filter plates can be easily replaced. During installation, ensure that the sealing ring at the bottom of the sealing cover matches the sealing groove at the top of the filter box to enhance the sealing performance and prevent leakage of untreated gas. Then, follow the reverse steps of disassembly. After the filter box and the sealing cover are completely fixed, unscrew the anti-loosening nut on the screw to engage with the rectangular frame limiting notch block. This prevents the notch block from shifting during operation and ensures that it effectively limits the notch plate. This process facilitates filter plate replacement and ensures the firmness and sealing of the connection between the filter box and the sealing cover, ensuring long-term stable operation of the device. 2. By setting up a filtration section, when using this device to treat the exhaust gas generated during material drying, multiple fans can be started to draw air to the outside, creating a negative pressure inside the filter box. The negative pressure is transmitted to the suction hood through multiple connecting pipes, which generates suction, thereby drawing the exhaust gas into the filter box. After being filtered layer by layer by multiple filter plates inside the box, the clean air can be smoothly discharged. This setup can achieve efficient collection and purification of exhaust gas from material drying, ensuring that the emitted air meets environmental protection requirements and protects the human body from harm.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5 As shown, this utility model is a drying box for drying and curing coating materials, including a drying box 1, and further including: a fixing part 2, which is disposed on the top of the drying box 1; and a filter part 3, which is disposed on the top of the drying box 1.

[0018] The fixing part 2 includes a fixing component 21, which is disposed on the top of the drying oven 1; and a limiting component 22, which is mounted on the fixing component 21. The fixing component 21 includes a filter box 211 fixedly connected to the top of the drying oven 1. A sealing cover 212 is provided on the top of the filter box 211. Notch plates 213 are fixedly connected to both sides of the sealing cover 212. Limiting grooves 214 are provided on both notch plates 213. Rectangular frames 215 are fixedly connected to both sides of the filter box 211. Notch blocks 216 are slidably connected to both rectangular frames 215. Two sliding rods 217 are slidably connected to both rectangular frames 215. The ends of several sliding rods 217 that are close to each other are connected to the two notch blocks 216. Each component is equipped with a reset element. Two notched locking blocks 216 are adapted to two limiting grooves 214. The reset element includes springs 218 wound around the outer walls of several sliding rods 217. One end of each spring 218 is fixedly connected to the two notched locking blocks 216, and the other end is fixedly connected to two rectangular frames 215. The limiting assembly 22 includes screws 221 fixedly connected to the two notched locking blocks 216. The ends of the two screws 221 that are far apart from each other extend outside the two rectangular frames 215 and are slidably connected to them. Anti-loosening nuts 222 are threaded onto the outer walls of the two screws 221. Limiting elements are provided on both screws 221. The ends of the two anti-loosening nuts 222 that are far apart from each other are fixedly connected to the two rectangular frames 215. The two screws 221 are in contact with each other. The limiting component includes a limiting nut 223 that is threaded to the outer wall of the two screws 221. The two limiting nuts 223 are in contact with the two rectangular frames 215 on the side that is close to each other. By setting the fixing part 2, when multiple filter plates 312 need to be replaced after a long period of filtration, the operation steps are as follows: First, pull the notch block 216 outward, so that it drives the upper screw 221 to slide outward on the rectangular frame 215, thereby releasing the limiting of the notch block 216 on the notch plate 213 on the filter box 211. At the same time, during the outward movement of the notch block 216, the two sliding rods 217 on it will move outward synchronously and compress the spring 218 on the rod synchronously, so that the spring accumulates elastic potential energy to provide power support for subsequent reset. After the notch block 216 is moved to the appropriate position, the limiting nut 223 on the screw 221 is screwed inward, allowing the limiting nut 223 to temporarily limit the notch block 216 with the help of the rectangular frame 215. This gives the operator sufficient time to disassemble the same structure on the other side. After both fixing mechanisms are released from their limiting positions, the sealing cover 212 can be separated from the filter box 211, making it easy to replace the multiple filter plates 312 inside the box. When installing the filter plates 312 after replacement, ensure that the sealing ring 315 at the bottom of the sealing cover 212 matches the sealing groove 314 at the top of the filter box 211. This setting effectively enhances the sealing performance of the filter box 211, prevents leakage of untreated gas inside the box, and ensures the waste gas treatment effect.The installation process for filter box 211 and sealing cover 212 is the reverse of the disassembly steps. It is particularly important to note that after filter box 211 and sealing cover 212 are completely fixed, the anti-loosening nuts 222 on the two screws 221 must be unscrewed. These anti-loosening nuts 222, in conjunction with the rectangular frame 215, limit the notch-shaped locking block 216 on the screws 221, preventing displacement during operation. This ensures the stable and effective limiting effect of the notch-shaped locking block 216 on the notch-shaped locking plate 213 on filter box 211. This design guarantees the firmness and sealing of the connection between filter box 211 and sealing cover 212, ensuring long-term stable operation of the device.

[0019] The filter section 3 includes a filter assembly 31, which is disposed on the top of the drying chamber 1; and a configuration assembly 32, which is mounted on the filter assembly 31. The filter assembly 31 includes several slots 311 formed in the inner wall of the bottom of the filter chamber 211, in which filter plates 312 are slidably connected. Several fans 313 are disposed on the left side of the filter chamber 211, and a sealing element is disposed on the filter chamber 211. Three fans 313 are disposed. The configuration assembly 32 includes several connecting pipes 321 fixedly connected to the right side of the filter chamber 211. An air suction hood 322 is fixedly connected to the top of the drying chamber 1 and communicates with the drying chamber 1. The right ends of the several connecting pipes 321 are fixedly connected to the air suction hood 322, and the several connecting pipes 321 communicate with both the filter chamber 211 and the air suction hood 322. The sealing element includes several slots 311 formed in the inner wall of the bottom of the filter chamber 211. The top of the filter box 211 has a sealing groove 314, and the bottom of the sealing cover 212 is fixedly connected to a sealing ring 315. The bottom of the sealing ring 315 extends into the sealing groove 314 and is adapted to the sealing groove 314. By setting the filter section 3, when using the device to treat the exhaust gas generated by material drying, multiple fans 313 can be started. Multiple fans 313 can draw air to the outside, so that a negative pressure is formed in the filter box 211. The negative pressure is conducted to the suction hood 322 connected to it through multiple connecting pipes 321, so that it generates suction, thereby drawing the exhaust gas into the filter box 211. After the exhaust gas is filtered layer by layer by multiple filter plates 312 in the filter box 211, the clean air can be smoothly discharged from the filter box 211. Through this setting, the efficient collection and purification treatment of exhaust gas from material drying can be achieved, ensuring that the exhaust air meets environmental protection requirements and protecting the human body from harm.

[0020] One specific application of this embodiment is: Drying oven 1 for drying and curing coating materials: It is a device used to achieve curing and shaping of coating materials. The stability of its temperature control and the uniformity of the heat field distribution directly affect the adhesion strength, weather resistance and surface smoothness of the coating. Different types of coating materials have different requirements for the temperature control of the drying oven. For example, epoxy powder coatings need to be cured at a constant temperature of 180-200℃, while water-based coatings need to undergo a stepped temperature increase of "low temperature dehydration and medium temperature film formation".

[0021] Fan 313: This is a specialized power unit used in industrial production to drive the flow of waste gas generated during the drying process of materials such as plastics, metals, chemical raw materials, and agricultural products. Its core function is to stably and efficiently transport the humid gases and volatile organic compounds (VOCs) such as benzene, alcohols, dust particles, or odorous gases emitted during the drying process to subsequent waste gas treatment systems such as adsorption towers, spray purification towers, catalytic combustion devices, and bag filters. This ensures that the waste gas meets environmental emission standards after purification treatment, while also ensuring pressure balance and air circulation within the drying equipment and workshop. Specific models include the F4-72-12No.4.5B fiberglass fan, made of acid and alkali resistant material, suitable for treating waste gas from chemical raw material drying.

[0022] When using this device to treat the exhaust gas generated during material drying, multiple fans 313 can be activated. These fans draw air outwards, creating a negative pressure inside the filter box 211. This negative pressure is transmitted through multiple connecting pipes 321 to the connected suction hood 322, generating suction that draws the exhaust gas into the filter box 211. After being filtered layer by layer by multiple filter plates 312 within the filter box 211, clean air can be smoothly discharged from the filter box 211. This setup achieves efficient collection and purification of exhaust gas from material drying, ensuring that the emitted air meets environmental protection requirements and protects human health. When multiple filter plates 312... 12. When the filter needs to be replaced after a long period of filtration, the operating steps are as follows: First, pull the notch block 216 outward, causing it to drive the screw 221 above it to slide outward on the rectangular frame 215, thereby releasing the notch block 216 from limiting the notch plate 213 on the filter box 211. At the same time, as the notch block 216 moves outward, the two sliding rods 217 on it will move outward synchronously and compress the spring 218 on the rod, allowing the spring to accumulate elastic potential energy to provide power support for subsequent reset. After the notch block 216 moves to the appropriate position, screw the limiting nut 223 on the screw 221 inward, allowing the limiting nut 223 to be used with the help of the torque. The frame 215 temporarily limits the notch block 216, allowing the operator sufficient time to disassemble the same structure on the other side. After both fixing mechanisms are released, the sealing cover 212 can be separated from the filter box 211, facilitating the replacement of multiple filter plates 312 inside the box. When installing after replacing multiple filter plates 312, ensure that the sealing ring 315 at the bottom of the sealing cover 212 matches the sealing groove 314 at the top of the filter box 211. This effectively enhances the sealing of the filter box 211, preventing leakage of untreated gas and ensuring the exhaust gas treatment effect. Simultaneously, the filter box 211 and... The installation process of the sealing cover 212 is the reverse of the disassembly steps. It is particularly important to note that after the filter box 211 and the sealing cover 212 are completely fixed, the anti-loosening nuts 222 on the two screws 221 need to be unscrewed outwards. The two anti-loosening nuts 222, together with the rectangular frame 215, limit the notch block 216 on the screw 221, preventing it from shifting during the operation of the device. This ensures that the notch block 216 effectively limits the notch plate 213 on the filter box 211. Through this setting, the firmness and sealing of the connection between the filter box 211 and the sealing cover 212 can be guaranteed, ensuring the long-term stable operation of the device.
