Description

Technical Field

[0001] This utility model relates to the technical field of impregnated paper production equipment, and in particular to an environmentally friendly drying device for impregnated paper production. Background Technology

[0002] An environmentally friendly drying device for impregnated paper production is a drying treatment equipment specifically used in the impregnated paper production process. Its core function is to dry and cure the paper after it has been impregnated with resin. By controlling conditions such as temperature and airflow, it removes excess moisture and volatile substances from the paper, ensuring that the impregnated paper reaches the specified degree of dryness and physical properties.

[0003] During the processing of impregnated paper, the paper needs to be impregnated with sizing agent. After impregnation, the paper needs to be dried. During the drying process of impregnated paper, formaldehyde will inevitably be released, which is not only harmful to human health, but also pollutes the environment. Existing formaldehyde removal methods mostly involve spraying formaldehyde cleaning liquid. However, directly spraying formaldehyde cleaning liquid is wasteful of water resources and the formaldehyde cleaning liquid is not used fully. An existing patent (publication number: CN219410344U) discloses a production equipment for formaldehyde-removing and environmentally friendly impregnated paper. This equipment includes a drying shell with a conveying device for conveying the impregnated paper inserted inside. Above the conveying device is a purification device for removing formaldehyde. Air guide devices are located on both sides of the purification device, facing each other, with the side of the air guide device furthest from the purification device fixedly connected to the inner wall of the drying shell. This new formaldehyde-removing and environmentally friendly impregnated paper production equipment utilizes a purification device that continuously overflows and circulates water, thus agitating the cleaning solution and ensuring more uniform mixing, which is beneficial for formaldehyde removal. This also saves water resources to some extent. Furthermore, the formaldehyde cleaning solution comes into contact with formaldehyde-containing air multiple times, allowing for more efficient use of the solution.

[0004] To address the aforementioned issues, existing patents offer solutions. However, existing environmentally friendly drying devices used in impregnated paper production generate exhaust gases containing VOCs, fiber debris, and oil during use. These exhaust gases are prone to unorganized diffusion during the drying process, polluting the workshop environment and endangering the health of operators. Furthermore, exhaust gas treatment often employs a single filtration method, which is insufficient to effectively separate different types of impurities in the exhaust gas, resulting in poor filtration performance and failing to meet environmental emission requirements.

[0005] Therefore, an environmentally friendly drying device for impregnated paper production is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an environmentally friendly drying device for impregnated paper production, which can solve the problems of existing environmentally friendly drying devices for impregnated paper production generating exhaust gas containing VOCs, fiber debris and oil during use. During the drying process, the exhaust gas is prone to unorganized diffusion, polluting the workshop working environment and endangering the health of operators. At the same time, exhaust gas treatment mostly adopts a single filtration method, which is difficult to effectively separate different types of impurities in the exhaust gas, resulting in poor filtration effect and difficulty in meeting environmental emission requirements.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly drying device for impregnated paper production, comprising a device body, a cover fixedly connected to the top of the device body, a fan mechanism fixedly connected to the top of the cover, a connecting pipe fixedly connected to the top of the fan mechanism, a preliminary filter box fixedly connected to the right side of the connecting pipe, a secondary filter box provided to the right side of the preliminary filter box, the fan mechanism comprising a fan frame, a fixing component fixedly connected to the inner wall of the fan frame, and a fan assembly fixedly connected to the inner wall of the fixing component.

[0008] Preferably, the inner wall of the cover is provided with a cavity, and the bottom of the air guide frame is fixedly connected to the top of the cover.

[0009] Preferably, a transmission pipe is fixedly connected to the right side of the primary filter box, and the right side of the transmission pipe is fixedly connected to the left side of the secondary filter box.

[0010] Preferably, the inner wall of the secondary filter box is bolted with a sealing plate, and a plug is fixedly connected to the rear side of the sealing plate.

[0011] Preferably, the surface of the insert block is inserted into the inner wall of the secondary filter box, and an activated carbon filter plate is inserted into the inner wall of the insert block.

[0012] Preferably, the inner wall of the insert block is provided with an air passage groove, and the inner wall of the insert block is provided with an installation groove for use with the activated carbon filter plate.

[0013] Preferably, a sealing ring is adhered to the inner wall of the sealing plate, and the surface of the sealing ring is engaged with the inner wall of the secondary filter box.

[0014] Preferably, a support assembly is fixedly connected to the rear side of the secondary filter box, and the front side of the support assembly is fixedly connected to the rear side of the device body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up an exhaust fan mechanism, allows the exhaust gas containing VOCs, fiber debris, and oil generated during the drying of impregnated paper in the device body to be collected through a hood fixed to the top of the device body, preventing the exhaust gas from spreading unorganized into the workshop environment. The exhaust fan mechanism fixed to the top of the hood can provide auxiliary exhaust fan, and the fixing components on the inner wall of the exhaust fan frame can firmly fix the fan assembly, ensuring the continuous and efficient operation of the fan assembly. The collected exhaust gas is stably transmitted to the preliminary filter box through the connecting pipe, providing stable airflow conditions for the subsequent filtration stage and effectively improving the exhaust gas collection efficiency. 2. This application, by setting up a preliminary filter box, can first intercept fiber debris and large particulate impurities, preventing impurities from entering the subsequent treatment stages with the exhaust gas and causing blockages. The exhaust gas after preliminary filtration is further transmitted to the inner wall of the secondary filter box. The activated carbon in the secondary filter box (generated by an external exhaust fan) adsorbs and purifies VOCs and residual oil, significantly reducing the pollutant content in the exhaust gas and meeting environmental emission requirements. Furthermore, the synergistic effect of the two-stage filtration can improve the overall filtration effect and extend the maintenance cycle of subsequent emission equipment.

[0018] 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.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: An environmentally friendly drying device for impregnated paper production includes a device body 1, a cover 3 fixedly connected to the top of the device body 1, an air-guiding mechanism 2 fixedly connected to the top of the cover 3, a connecting pipe 4 fixedly connected to the top of the air-guiding mechanism 2, a preliminary filter box 5 fixedly connected to the right side of the connecting pipe 4, a secondary filter box 6 provided to the right side of the preliminary filter box 5, the air-guiding mechanism 2 includes an air-guiding frame 201, a fixing component 202 fixedly connected to the inner wall of the air-guiding frame 201, and a fan assembly 203 fixedly connected to the inner wall of the fixing component 202.

[0020] In this embodiment: By setting up the exhaust gas mechanism 2, the exhaust gas containing VOCs, fiber debris, and oil generated when the device body 1 dries the impregnated paper can be collected by the cover 3 fixed to the top of the device body 1, preventing the exhaust gas from spreading unorganized into the workshop environment. The exhaust gas mechanism 2 fixed to the top of the cover 3 can provide auxiliary exhaust gas. The fixing component 202 on the inner wall of the exhaust frame 201 can firmly fix the fan assembly 203, ensuring that the fan assembly 203 operates continuously and efficiently. The collected exhaust gas is stably transmitted to the preliminary filter box 5 through the connecting pipe 4, providing stable airflow conditions for the subsequent filtration stage and effectively improving the efficiency of the filter. The exhaust gas collection efficiency is improved by setting up a preliminary filter box 5, which can first intercept fiber debris and large particulate impurities, preventing impurities from entering the subsequent treatment stages and causing blockages. The exhaust gas after preliminary filtration is further transmitted to the inner wall of the secondary filter box 6. The activated carbon in the secondary filter box 6 (generated by an external induced draft fan) adsorbs and purifies VOCs and residual oil, significantly reducing the pollutant content in the exhaust gas and meeting environmental emission requirements. Furthermore, the synergistic effect of the two-stage filtration can improve the overall filtration effect and extend the maintenance cycle of subsequent emission equipment.

[0021] Specifically, such as Figure 3 As shown, the inner wall of the cover 3 is provided with a cavity 7, and the bottom of the air guide frame 201 is fixedly connected to the top of the cover 3.

[0022] Specifically, such as Figure 4 As shown, a transmission pipe 8 is fixedly connected to the right side of the primary filter box 5, and the right side of the transmission pipe 8 is fixedly connected to the left side of the secondary filter box 6.

[0023] Specifically, such as Figure 5 As shown, a sealing plate 9 is bolted to the inner wall of the secondary filter box 6, and an insert block 10 is fixedly connected to the rear side of the sealing plate 9.

[0024] In this embodiment: the cavity 7 provides a temporary storage and guiding space for the exhaust gas, which can reduce turbulence during the exhaust gas collection process and improve the gathering effect of the hood 3 on the exhaust gas. The fixed connection between the bottom of the induced draft frame 201 and the top of the hood 3 ensures that the induced draft mechanism 2 and the hood 3 form a rigid whole, avoiding loosening of the connection due to vibration during induced draft. The transmission pipe 8 fixedly connected to the right side of the primary filter box 5 is directly connected to the secondary filter box 6, so that the exhaust gas after primary filtration can accurately enter the secondary filter box 6 through the closed channel, reducing exhaust gas leakage during transmission and ensuring the continuity and efficiency of the two-stage filtration.

[0025] Specifically, such as Figure 5 , Figure 6 As shown, the surface of the insert 10 is inserted into the inner wall of the secondary filter box 6, and an activated carbon filter plate 11 is inserted into the inner wall of the insert 10.

[0026] Specifically, such as Figure 6 As shown, the inner wall of the insert 10 is provided with an air passage groove 12, and the inner wall of the insert 10 is provided with an installation groove 13 for use with the activated carbon filter plate 11.

[0027] In this embodiment: the insertion block 10 and the inner wall of the secondary filter box 6 provide a quick positioning and installation structure for the sealing plate 9, which facilitates the disassembly and assembly of the sealing plate 9. The mounting groove 13 on the inner wall of the insertion block 10 can form a stable limit on the activated carbon filter plate 11, ensuring that it does not shift under the impact of exhaust gas. The air passage groove 12 can guide the exhaust gas to flow evenly through the activated carbon filter plate 11, improve the adsorption and purification efficiency, and at the same time facilitate the quick replacement of the activated carbon filter plate 11 according to the filtration requirements, reducing the maintenance difficulty.

[0028] Specifically, such as Figure 6 As shown, a sealing ring 14 is bonded to the inner wall of the sealing plate 9, and the surface of the sealing ring 14 is engaged with the inner wall of the secondary filter box 6.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, a support assembly 15 is fixedly connected to the rear side of the secondary filter box 6, and the front side of the support assembly 15 is fixedly connected to the rear side of the device body 1.

[0030] In this embodiment: by setting the sealing ring 14, the sealing performance of the secondary filter box 6 can be enhanced, preventing unpurified exhaust gas from leaking from the gap between the sealing plate 9 and the box body, thus ensuring the filtration effect. The support component 15 on the rear side of the secondary filter box 6 is fixedly connected to the rear side of the device body 1, which can form a stable support for the secondary filter box 6, preventing it from shaking due to its own weight or airflow impact, enhancing the stability of the overall structure, and ensuring the structural reliability during long-term use.

[0031] Working Principle: During the use of the device body 1, the exhaust gas containing VOCs, fiber debris, and oil generated when the device body 1 dries impregnated paper is collected by the hood 3 fixed to the top of the device body 1 through the exhaust fan mechanism 2. This prevents the exhaust gas from spreading unorganized into the workshop environment. The exhaust fan mechanism 2 fixed to the top of the hood 3 provides auxiliary exhaust. The fixing component 202 on the inner wall of the exhaust fan frame 201 can firmly fix the fan assembly 203, ensuring that the fan assembly 203 operates continuously and efficiently. The collected exhaust gas is stably transmitted to the preliminary filter box 5 through the connecting pipe 4, providing a stable airflow for subsequent filtration stages. This system effectively improves exhaust gas collection efficiency. By setting up a preliminary filter box 5, fiber debris and large particulate impurities can be intercepted first, preventing impurities from entering subsequent treatment stages and causing blockages. The exhaust gas after preliminary filtration is further transmitted to the inner wall of the secondary filter box 6. The activated carbon in the secondary filter box 6 (generated by an external induced draft fan) adsorbs and purifies VOCs and residual oil, significantly reducing the pollutant content in the exhaust gas and meeting environmental emission requirements. Furthermore, the synergistic effect of the two-stage filtration can improve the overall filtration effect and extend the maintenance cycle of subsequent emission equipment.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
