Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to a vapor phase anti-rust paper drying equipment. Background Art

[0002] VCI paper is a specialized, rust-resistant packaging material made from specialized neutral paper, coated with a special substance—Vapor Corrosion Inhibitor (VCI)—of varying formulations, and then undergoing a series of post-processing steps. Among the many materials used in the packaging industry, VCI paper represents a high-tech product, with VCI as its core technology. VCI technology is a comprehensive approach that integrates organic synthesis, physical chemistry, corrosion protection, metal materials, paper processing, and polymers.

[0003] The basic manufacturing process of vapor phase anti-rust paper consists of four parts. First, the vapor phase corrosion inhibitors used are dissolved in deionized water in the order of dissolution and stirred evenly to prepare a VCI aqueous solution; the VCI aqueous solution is applied to the anti-rust base paper by roller coating or spraying, and attention should be paid to controlling the amount of VCI coating during coating; after applying the VCI solution, the paper needs to be dried. During drying, the drying temperature should not be too high to avoid excessive loss of vapor phase corrosion inhibitors, and the moisture content of the paper should be controlled within a reasonable range; after drying, the anti-rust paper is rolled up and the paper roll is subsequently cut into rolls or sheets as needed.

[0004] To ensure the quality and performance of VCI paper, drying equipment is an essential and critical step. Existing VCI paper drying equipment primarily consists of single-layer conveyor belt dryers, typically employing a hot air circulation system. This system heats air through heating elements and blows it over the paper, rapidly drying it and removing moisture and other volatile substances, thereby ensuring the paper's rust-proofing effectiveness.

[0005] However, since there is an overlapping area between the conveyor belt and the anti-rust paper, when the hot air circulates under the conveyor belt, less heat energy is transferred to the anti-rust paper in the overlapping area due to the obstruction of the conveyor belt, resulting in uneven drying effect on the side of the anti-rust paper close to the conveyor belt and the drying effect may be slightly worse than that on the other side, affecting the quality and performance of the anti-rust paper. Summary of the Invention

[0006] In order to improve the uniformity of the drying effect on both sides of the anti-rust paper and improve the quality and performance of the anti-rust paper, the present application provides a vapor phase anti-rust paper drying device.

[0007] The present application provides a vapor phase anti-rust paper drying equipment, which adopts the following technical solution: it includes a drying box and a drying component arranged in the drying box, a plurality of conveying rollers are rotatably arranged in the drying box, the axes of the plurality of conveying rollers are parallel to each other, the rotation axes of the conveying rollers are parallel to the axes of the conveying rollers, and the plurality of conveying rollers are staggered and distributed in the drying box up and down, the drying component is provided with multiple groups, the multiple groups of drying components and the multiple conveying rollers correspond one to one, adjacent drying components are respectively located on the mutually distant sides of adjacent conveying rollers, a gap for the anti-rust paper to pass through is formed between the drying component and the conveying rollers, and the conveying rollers are used to drive the anti-rust paper to be transported in the drying box.

[0008] By adopting the above technical solution, multiple conveying rollers are staggered up and down and adjacent drying components are located on the sides of the adjacent conveying rollers away from each other. When the anti-rust paper passes between the drying components and the conveying rollers, the heat of the drying components can be effectively guided to be evenly distributed on various parts on both sides of the anti-rust paper, thereby improving the uniformity of the drying effect on both sides of the anti-rust paper and improving the quality and performance of the anti-rust paper.

[0009] Preferably, a plurality of partition plates are provided in the drying box, and the plurality of partition plates are parallel to each other and arranged at intervals in the drying box. The plurality of partition plates correspond one to one with the plurality of conveying rollers.

The plurality of drying components can independently adjust the drying temperature, and the plurality of partition plates divide the drying box into a plurality of drying areas.

[0010] By adopting the above technical solution, the partition plate divides the drying box into multiple drying zones and multiple drying components can independently adjust the drying temperature, so that the drying temperature of each drying zone can be different. The drying temperature of the drying zone close to the side where the anti-rust paper enters the drying box can be set to a relatively low temperature, so as to achieve the effect of preheating the anti-rust paper. The drying temperature of the drying zone close to the side where the anti-rust paper leaves the drying box can also be set to a relatively low temperature, so as to reduce the difficulty of heat dissipation and cooling after the anti-rust paper is dried and discharged. Moreover, the separation of multiple drying zones can adjust the drying temperature of each drying zone in real time, effectively saving heat energy.

[0011] Preferably, a scraping assembly is provided on the side of the partition plate close to the conveying roller, and the end of the scraping assembly away from the partition plate is attached to the roller wall of the conveying roller, and the scraping assembly is used to scrape off adhesions on the roller wall of the conveying roller, and an ash collection port is provided on the side of the partition plate close to the conveying roller, and the ash collection port and the scraping assembly are adjacently arranged on the side wall of the partition plate close to the conveying roller, and an ash collection cavity is provided in the partition plate, and the ash collection port and the ash collection cavity are communicated with each other, and the ash collection cavity is used to receive and collect adhesions on the conveying roller scraped off by the scraping assembly.

[0012] During the transportation of the anti-rust paper driven by the conveyor roller, there is always contact between the anti-rust paper and the conveyor roller. Dust and impurities may adhere to the anti-rust paper, and the dust and impurities adhered to the anti-rust paper may adhere to the roller wall of the conveyor roller when in contact with the conveyor roller. In addition, the vapor corrosion inhibitor on the anti-rust paper may be lost during the drying process, and the lost vapor corrosion inhibitor may also adhere to the roller wall of the conveyor roller. During the rotation of the conveyor roller, the dust and impurities adhered to the roller wall and the vapor corrosion inhibitor may adhere to the anti-rust paper in reverse, affecting the quality and performance of the anti-rust paper. By adopting the above technical solution, when dust and impurities and vapor corrosion inhibitor adhere to the roller wall of the conveyor roller, its local wall thickness will increase, and the scraping component will be attached to the roller wall of the conveyor roller. During the rotation of the conveyor roller, the dust and impurities adhered to the roller wall and the vapor corrosion inhibitor will be scraped off by the scraping component, and the scraped dust and impurities and vapor corrosion inhibitor will be received and collected in the dust collecting chamber, thereby improving the quality and performance of the anti-rust paper.

[0013] Preferably, the drying box is penetrated by a plurality of waste discharge ports, the plurality of waste discharge ports correspond one to one with a plurality of partition plates, and the waste discharge ports are communicated with one end of the ash collecting chamber away from the ash collecting ports.

[0014] By adopting the above technical solution, not only can the dust impurities and vapor corrosion inhibitor collected in the ash collecting chamber be discharged from the waste outlet, so that the ash collecting chamber can maintain the ability to collect adhesions on the conveying roller, but also the water vapor generated during the drying process can be easily discharged, thereby reducing the humidity inside the drying box and improving the drying efficiency.

[0015] Preferably, the scraping assembly includes a scraper blade and a scraper seat, one side of the scraper blade is attached to the roller wall of the conveying roller, the length direction of the scraper blade is parallel to the axial direction of the conveying roller and the length of the scraper blade is equal to the axial length of the conveying roller, the cross-section of the scraper blade is arc-shaped, the inner arc surface of the scraper blade faces the ash collection port, the other side of the scraper blade is connected to the scraper seat, and the scraper seat is inserted into the partition plate away from the scraper blade.

[0016] By adopting the above technical solution, the scraper blade, which is as long as the conveyor roller, can evenly scrape off the adhesions on the roller wall of the conveyor roller during the rotation of the conveyor roller, and the arc shape of the scraper blade serves as a guide for the scraped adhesions, thereby increasing the probability of the adhesions entering the ash collection chamber.

[0017] Preferably, the drying component includes a drying arc plate and an electric heating element embedded in the drying arc plate, the outer arc side of the drying arc plate is connected to the inner wall of the drying box, and there is a gap between the inner arc side of the drying arc plate and the conveying roller for the rust-proof paper to pass through, and a drying cavity for embedding the electric heating element is opened in the drying arc plate, and the electric heating elements are evenly distributed in the drying cavity.

[0018] By adopting the above technical solution, when current passes through the electric heating element, the current will generate heat when passing through the conductor. This heat is transferred by the conductor, thereby achieving the effect of the electric heating element converting electrical energy into thermal energy. The electric heating elements evenly distributed in the drying chamber will evenly transfer the heat to the plate surface of the drying arc plate, and then the anti-rust paper will be heated and dried by the drying arc plate. The curvature of the drying arc plate that fits the roller wall of the conveyor roller increases the contact area with the anti-rust paper to a certain extent, thereby improving the drying efficiency.

[0019] Preferably, the drying component also includes a drying fan, which is arranged on the outer arc side of the drying arc plate. The air outlet of the drying fan is connected to the drying chamber. Air outlet nozzles are provided on the end faces of both ends of the drying arc plate, and the air outlet nozzles are connected to the drying chamber.

[0020] By adopting the above technical solution, the drying fan drives the air in the drying box to flow, which is not only conducive to faster transmission of heat generated by the electric heating element and improved drying efficiency, but also makes the heat received by both sides of the anti-rust paper more evenly, improves the uniformity of the drying effect on both sides of the anti-rust paper, and improves the quality and performance of the anti-rust paper.

[0021] Preferably, the drying box is further provided with a detachable ash collecting part, which is used to fill the ash collecting cavity from the waste outlet, and is used to receive and collect the adhesions on the conveying roller scraped off by the scraping assembly.

[0022] Since the conveying rollers are staggered in distribution up and down, several of the waste outlets are opened on the box wall at the bottom of the drying box, and the remaining waste outlets are opened on the box wall at the top of the drying box. The adhesions in the ash collecting chamber connected to the waste outlet at the bottom of the drying box can be discharged from the waste outlet by their own weight and continuous accumulation, but the discharge of adhesions in the ash collecting chamber connected to the waste outlet at the top of the drying box is difficult, and the accumulation of adhesions in the ash collecting chamber will affect its ability to continue to carry and collect adhesions. By adopting the above technical solution, the detachable ash collecting part is filled into the ash collecting chamber, and the detachable ash collecting part replaces the ash collecting chamber to receive and collect adhesions scraped off the conveying rollers. When the adhesions collected in the detachable ash collecting part are in a saturated state, the detachable ash collecting part can be removed from the ash collecting chamber.

[0023] Preferably, the detachable ash collecting part includes an ash collecting hopper with an open top, the four outer walls of the ash collecting hopper are respectively attached to the four inner walls of the ash collecting cavity, and the bottom of the ash collecting hopper is penetrated by an ash opening. The detachable ash collecting part also includes a sealing plate embedded in the bottom of the ash collecting hopper, and the ash collecting hopper is provided with a driving part for driving the sealing plate to seal the ash opening.

[0024] By adopting the above technical solution, the ash collecting hopper replaces the ash collecting chamber to receive and collect the adhesions scraped off the conveyor roller. When the adhesions collected in the ash collecting hopper tend to be saturated, the driving member drives the sealing plate to seal the ash opening and then removes the ash collecting hopper from the ash collecting chamber. Then, an empty ash collecting hopper is installed to continue receiving the adhesions scraped off the conveyor roller.

[0025] Preferably, an embedding cavity for embedding the sealing plate is provided at the bottom of the ash hopper, and one side of the embedding cavity passes through the bottom of the ash hopper to be connected with the ash opening, and the sealing plate and one side wall of the ash hopper are relatively fixed by a positioning piece, and the positioning piece is provided on the sealing plate, and the sealing plate is used to slide and embed into one side wall of the ash hopper, and one end of the driving piece is attached to the positioning piece and is used to make the positioning piece slide away from one side wall of the ash hopper.

In this embodiment, four conveying rollers 130 are rotatably arranged in the drying box 110. The axes of the four conveying rollers 130 are parallel to each other. The rotation axes of the conveying rollers 130 are parallel to the axes of the conveying rollers 130. The four conveying rollers 130 are staggered up and down in the drying box 110. The anti-rust paper 1 passes through the four conveying rollers 130 from top to bottom. The conveying rollers 130 are used to drive the anti-rust paper 1 to be transported in the drying box 110. The opposite side walls of the box 10 are respectively penetrated by a feed port 111 and a discharge port 112, and the drying components 120 and the conveying rollers 130 correspond to each other one by one, and a total of four groups are provided. Adjacent drying components 120 are respectively located on the mutually away sides of adjacent conveying rollers 130, and a gap is formed between the drying components 120 and the conveying rollers 130 for the anti-rust paper 1 to pass through, which can effectively guide the heat of the drying components 120 to be evenly distributed in various parts on both sides of the anti-rust paper 1, thereby improving the uniformity of the drying effect on both sides of the anti-rust paper 1 and improving the quality and performance of the anti-rust paper 1.

[0039] Specifically, refer to Figure 2 、 Figure 3The drying assembly 120 includes a drying arc plate 121, an electric heating element 122 embedded in the drying arc plate 121, and a drying fan 123. In this embodiment, the cross-section of the two drying arc plates 121 close to the box walls on both sides of the drying box 110 is a quarter arc, while the cross-section of the two drying arc plates 121 away from the box walls on both sides of the drying box 110 is a semicircular arc. A connecting plate 124 is provided at the midpoint of the outer arc side of the drying arc plate 121. The side of the connecting plate 124 away from the drying arc plate 121 is connected to the inner wall of the drying box 110. There is a gap between the inner arc side of the drying arc plate 121 and the conveying roller 130 for the rust-proof paper 1 to pass through. The drying arc plate 121 is provided with an electric heating element. 122 is embedded in a drying chamber 125, and the electric heating elements 122 are evenly distributed in the drying chamber 125 in an S shape; the drying fans 123 are arranged on the outer arc side of the drying arc plate 121, and the air outlet of the drying fans 123 is connected to the drying chamber 125. Two rows of drying fans 123 are provided on each drying arc plate 121, and the two rows of drying fans 123 are symmetrically arranged on both sides of the connecting plate 124. Each row of drying fans 123 includes multiple drying fans 123, and the multiple drying fans 123 in each row are equidistantly arranged on the drying arc plate 121 along the axial direction of the conveying roller 130. Air outlet nozzles 126 are provided on the end faces of both ends of the drying arc plate 121, and the air outlet nozzles 126 are connected to the drying chamber 125.

[0040] When current passes through the electric heating element 122, the current generates heat when passing through the conductor. This heat is transferred by the conductor, thereby achieving the effect of the electric heating element 122 converting electrical energy into thermal energy, and the electric heating elements 122 evenly distributed in the drying chamber 125 transfer the heat evenly to the plate surface of the drying arc plate 121, and then the rust-proof paper 1 is heated and dried by the drying arc plate 121. The curvature of the drying arc plate 121 that fits the roller wall of the conveying roller 130 increases the contact area with the rust-proof paper 1 to a certain extent; and the drying fan 123 drives the air in the drying box 110 to flow, which is not only conducive to faster transmission of the heat generated by the electric heating element 122 and improved drying efficiency, but also makes the heat received by both sides of the rust-proof paper 1 more uniform, improves the uniformity of the drying effect on both sides of the rust-proof paper 1, and improves the quality and performance of the rust-proof paper 1.

[0041] Further, refer to Figure 1 、 Figure 2, a plurality of partition plates 140 are provided in the drying box 110, and the plurality of partition plates 140 are parallel to each other and spaced apart in the drying box 110. In this embodiment, a total of four partition plates 140 are provided, and the four partition plates 140 correspond to the four transport rollers one by one. The partition plates 140 are provided on the side of the transport plate away from the drying assembly 120, and the side wall of one side of the partition plate 140 is connected to the inner wall of the drying box 110, and the side wall of the other side of the partition plate 140 is used to fit the roller wall of the transport roller 130. The partition plates 140 and the connecting plate 124 together The drying box 110 is divided into five drying zones 113, and the four drying components 120 can independently adjust the drying temperature, so that the drying temperature of each drying zone 113 is different. The drying temperature of the drying zone 113 close to the side where the rust-proof paper 1 enters the drying box 110 can be set relatively low, so as to achieve the effect of preheating the rust-proof paper 1. The drying temperature of the drying zone 113 close to the side where the rust-proof paper 1 leaves the drying box 110 can also be set relatively low, so as to reduce the difficulty of heat dissipation and cooling of the rust-proof paper 1 after drying and discharge, thereby effectively saving heat energy.

[0042] In addition, during the transportation of the anti-rust paper 1 driven by the conveying roller 130, there is always contact between the anti-rust paper 1 and the conveying roller 130. Dust and impurities may adhere to the anti-rust paper 1, and the dust and impurities adhered to the anti-rust paper 1 may adhere to the roller wall of the conveying roller 130 when in contact with the conveying roller 130. Moreover, the vapor corrosion inhibitor on the anti-rust paper 1 may be lost during the drying process, and the lost vapor corrosion inhibitor may also adhere to the roller wall of the conveying roller 130. During the rotation of the conveying roller 130, the dust and impurities and vapor corrosion inhibitor adhered to its roller wall may adhere to the anti-rust paper 1 in reverse, affecting the quality and performance of the anti-rust paper 1. Therefore, a scraping assembly 150 is provided on the side of the partition plate 140 close to the conveying roller 130, and the end of the scraping assembly 150 away from the partition plate 140 is attached to the roller wall of the conveying roller 130. The scraping assembly 150 is used to scrape off the adhesion on the roller wall of the conveying roller 130.

[0043] Specifically, refer to Figure 2 、 Figure 4The scraping assembly 150 includes a scraper blade 151 and a scraper seat 152. One side of the scraper blade 151 is attached to the roller wall of the conveying roller 130. The length direction of the scraper blade 151 is parallel to the axial direction of the conveying roller 130 and the length of the scraper blade 151 is equal to the axial length of the conveying roller 130. The cross section of the scraper blade 151 is arc-shaped; the side of the partition plate 140 close to the conveying roller 130 is provided with an ash collection port 141, and the scraper blade 151 and the ash collection port 141 are adjacently arranged on the partition plate 1 On the side wall of 40 close to the conveying roller 130, the inner arc surface of the scraper blade 151 faces the ash collecting port 141, and the other side of the scraper blade 151 is connected to the scraper seat 152, and the side of the scraper seat 152 away from the scraper blade 151 is inserted into the partition plate 140; an ash collecting cavity 142 is opened in the partition plate 140, and the ash collecting port 141 and the ash collecting cavity 142 are connected, and the ash collecting cavity 142 is used to receive and collect the adhesions on the conveying roller 130 scraped off by the scraping component 150.

[0046] In order to facilitate the adhesion scraped off the conveying roller 130 to enter the ash collecting chamber 142 through the ash collecting opening 141 , negative pressure members 143 are provided on both sides of the partition plate 140 to maintain a negative pressure state in the ash collecting chamber 142 .

[0047] The adhesions in the ash collecting chamber 142 connected to the waste outlet 114 at the bottom of the drying box 110 can be discharged from the waste outlet 114 by its own weight and continuous accumulation, but the discharge of adhesions in the ash collecting chamber 142 connected to the waste outlet 114 at the top of the drying box 110 is somewhat difficult, and the accumulation of adhesions in the ash collecting chamber 142 will affect its ability to continue to carry and collect adhesions. The drying box 110 can also be detachably provided with a detachable ash collecting part 160, which is used to fill the ash collecting chamber 142 from the waste outlet 114. The detachable ash collecting part 160 replaces the ash collecting chamber 142 to receive and collect adhesions scraped off from the conveying roller 130. When the adhesions collected in the detachable ash collecting part 160 are in a saturated state, the detachable ash collecting part 160 can be removed from the ash collecting chamber 142.
