Description

Technical Field

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

[0002] VCI paper is a special anti-rust packaging material made of special neutral paper as the base material, coated with special substances of different formulations - vapor corrosion inhibitor (VCI), and processed through a series of post-processing. Among the many materials in the packaging industry, VCI paper is a high-tech product, and its core technology is reflected in VCI. VCI technology is a comprehensive technology that integrates organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing and polymer technologies.

[0003] The basic manufacturing process of vapor phase anti-rust paper has four parts. First, the vapor phase corrosion inhibitors used are dissolved in deionized water in the order of dissolution, stirred evenly, and a VCI aqueous solution is prepared; the VCI aqueous solution is applied to the anti-rust base paper by roller coating or spraying, and attention should be paid to the control of the VCI coating amount during coating; the paper needs to be dried after coating with the VCI solution, and attention should be paid to the drying temperature not being too high to avoid excessive loss of the vapor phase corrosion inhibitor, 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] In order to ensure the quality and performance of VCI paper, drying equipment is an essential key link. Existing VCI paper drying equipment is mainly a single-layer conveyor belt dryer, which usually adopts a hot air circulation system. The air is heated by a heating element and blown over the anti-rust paper to make it dry quickly to remove moisture and other volatile substances in it, thereby ensuring the anti-rust effect of the anti-rust paper.

[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 scheme: 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, the plurality of conveying rollers are staggered and distributed up and down in the drying box, the drying component is provided with a plurality of groups, the plurality of groups of drying components and the plurality of conveying rollers correspond one to one, the adjacent drying components are respectively located on the mutually distant sides of the adjacent conveying rollers, a gap is formed between the drying component and the conveying rollers for the anti-rust paper to pass through, 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 adjacent conveying rollers that are far 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 in 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.

[0010] By adopting the above technical scheme, the partition plate divides the drying box into multiple drying zones and multiple drying components can independently adjust the drying temperature, so that the effect of different drying temperatures in each drying zone can be achieved. The drying temperature of the drying zone close to the side where the anti-rust paper enters the drying box can be set relatively low, 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 relatively low, so as to reduce the difficulty of heat dissipation and cooling of the anti-rust paper after drying and discharging.

[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 phase corrosion inhibitor on the anti-rust paper may be lost during the drying process, and the lost vapor phase 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 phase 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 scheme, when dust and impurities and vapor phase 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 phase corrosion inhibitor will be scraped off by the scraping component, and the scraped dust and impurities and vapor phase corrosion inhibitor will be received and collected in the ash collecting chamber, thereby improving the quality and performance of the anti-rust paper.

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

[0014] By adopting the above technical scheme, not only can the dust impurities and gas phase 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 discharged conveniently, thereby reducing the humidity inside the drying box and improving the drying efficiency.

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, and 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.

[0022] Since the conveying rollers are staggered in distribution up and down, several of the waste discharge ports are opened on the box wall at the bottom of the drying box, and the remaining waste discharge ports are opened on the box wall at the top of the drying box. The adhesions in the ash collecting chamber connected to the waste discharge port at the bottom of the drying box can be discharged from the waste discharge port by their own weight and continuous accumulation, but the discharge of adhesions in the ash collecting chamber connected to the waste discharge port 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-mentioned technical scheme, 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.

Then, an empty ash collecting hopper is installed to continue receiving the adhesions scraped off the conveying roller.

[0025] Preferably, an embedding cavity for embedding the sealing plate is provided at the bottom of the ash hopper, one side of the embedding cavity passes through the bottom of the ash hopper to be connected with the ash opening, the sealing plate and one side wall of the ash hopper are relatively fixed by a positioning piece, the positioning piece is arranged on the sealing plate, the sealing plate is used to slide and embed into one side wall of the ash hopper, 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 axial directions of the four conveying rollers 130 are parallel to each other. The rotation axis of the conveying rollers 130 is parallel to the axial direction 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 drying box 1 The opposite side walls of the box 10 are respectively penetrated with 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 distant 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 at 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.

[0033] 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, and 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 anti-rust 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 outlets of the drying fans 123 are connected to the drying chamber 125, and two rows of drying fans 123 are arranged 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, and each row of drying fans 123 includes a plurality of drying fans 123, and the plurality of drying fans 123 in each row are equidistantly arranged on the drying arc plate 121 along the axial direction of the conveying roller 130, and 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.

[0034] When current passes through the electric heating element 122, 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 122 converting electrical energy into thermal energy, and the electric heating element 122 evenly distributed in the drying chamber 125 transfers the heat evenly to the plate surface of the drying arc plate 121, and then the anti-rust 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 anti-rust 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 improves the drying efficiency, but also makes the heat received by both sides of the anti-rust paper 1 more uniform, improves the uniformity of the drying effect on both sides of the anti-rust paper 1, and improves the quality and performance of the anti-rust paper 1.

[0035] Further, refer to Figure 1 , Figure 2, a plurality of partition plates 140 are arranged in the drying box 110, and the plurality of partition plates 140 are arranged in parallel and at intervals in the drying box 110. In the present embodiment, a total of four partition plates 140 are arranged, and the four partition plates 140 correspond to the four transport rollers one by one. The partition plates 140 are arranged 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 are used to connect the drying assembly 120 to the drying assembly 120. The drying box 110 is divided into five drying areas 113, and the four drying components 120 can independently adjust the drying temperature, so that the drying temperature of each drying area 113 is different. The drying temperature of the drying area 113 close to the side where the anti-rust paper 1 enters the drying box 110 can be set relatively low, so as to achieve the effect of preheating the anti-rust paper 1. The drying temperature of the drying area 113 close to the side where the anti-rust 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 anti-rust paper 1 after drying and discharging, and effectively save heat energy.

[0036] 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. In addition, the vapor phase corrosion inhibitor on the anti-rust paper 1 may be lost during the drying process, and the lost vapor phase 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 phase 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, and the scraping assembly 150 is used to scrape off the adhesion on the roller wall of the conveying roller 130.

[0037] 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; a dust collecting port 141 is opened on one side of the partition plate 140 close to the conveying roller 130. The scraper blade 151 and the dust collecting port 141 are arranged adjacent to each other on the partition plate 1 On the side wall of one side 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 adhesion on the conveying roller 130 scraped off by the scraping assembly 150.

[0038] When dust impurities and vapor-phase corrosion inhibitors adhere to the roller wall of the conveying roller 130, its local wall thickness will increase, and the scraping component 150 will be attached to the roller wall of the conveying roller 130. During the rotation of the conveying roller 130, the dust impurities and vapor-phase corrosion inhibitors adhered to the roller wall will be scraped off by the scraping component 150, and the scraped dust impurities and vapor-phase corrosion inhibitors will be received and collected in the dust collecting chamber 142, thereby improving the quality and performance of the anti-rust paper 1.

[0039] Further, refer to Figure 1 , Figure 4 , the drying box 110 is penetrated by a plurality of waste discharge ports 114, and the plurality of waste discharge ports 114 correspond to the plurality of partition plates 140 one by one, and there are four waste discharge ports 114 in total. In the present embodiment, since the conveying rollers 130 are staggeredly distributed up and down, two of the waste discharge ports 114 are opened on the box wall at the bottom of the drying box 110, and the remaining two waste discharge ports 114 are opened on the box wall at the top of the drying box 110; the waste discharge port 114 is connected to the end of the ash collecting chamber 142 away from the ash collecting port 141, not only can the dust impurities and vapor phase corrosion inhibitor collected in the ash collecting chamber 142 be discharged from the waste discharge port 114, so that the ash collecting chamber 142 can maintain the ability to collect the adhesion on the conveying roller 130, avoiding excessive dust accumulation affecting the drying effect, but also conveniently discharge the water vapor generated during the drying process, reduce the humidity inside the drying box 110, and improve the drying efficiency.

[0040] In order to facilitate the adhesion scraped off the conveying roller 130 to enter the ash collecting chamber 142 from the ash collecting opening 141 , negative pressure members 143 are provided on both sides of the partition plate 140 to keep the ash collecting chamber 142 in a negative pressure state.

[0041] 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 the adhesions in the ash collecting chamber 142 connected to the waste outlet 114 at the top of the drying box 110 is 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 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.

[0042] Specifically, refer to Figure 1 , Figure 5 The detachable ash collecting part 160 includes an ash collecting hopper 161 and a sealing plate 162 embedded in the bottom of the ash collecting hopper 161. The shape of the ash collecting hopper 161 can be designed to be open at the top to facilitate loading and unloading, and the adhesion in the ash collecting cavity 142 can be cleaned regularly to maintain cleanliness; the four side outer walls of the ash collecting hopper 161 are respectively attached to the four side cavity inner walls of the ash collecting cavity 142, and the bottom of the ash collecting hopper 161 is penetrated by an ash opening 163. The ash collecting hopper 161 is provided with a driving part 164 for driving the sealing plate 162 to seal the ash opening 163. The design of the sealing plate 162 can reduce the probability of adhesion leakage during the removal of the ash collecting hopper 161, and keep the environment clean.

[0043] The bottom of the ash hopper 161 is provided with an embedding cavity 167 for embedding the sealing plate 162. One side of the embedding cavity 167 passes through the bottom of the ash hopper 161 to communicate with the ash opening 163. The sealing plate 162 and one side wall of the ash hopper 161 are relatively fixed by a positioning member 170. One end of the driving member 164 is attached to the positioning member 170. In this embodiment, the driving member 164 includes a driving rod 165 vertically inserted on the side wall of the ash hopper 161. One end of the driving rod 165 is partially exposed at the top of the ash hopper 161, and the other end of the driving rod 165 is in contact with the positioning member 170. The positioning member 170 includes a positioning block 171 and a positioning spring 172. The sealing plate 162 is close to the driving rod 165 on the side wall of the driving plate 162.

A driving slot 168 is opened on the side wall of one side of the ash hopper 161 for inserting the driving rod 165, and the driving slot 168 penetrates and is connected to the embedding cavity 167. The end of the positioning block 171 away from the positioning spring 172 is used to be inserted into the driving slot 168. The driving member 164 also includes a driving spring 166, one end of the driving spring 166 is connected to the side of the sealing plate 162 away from the ash opening 163, and the other end of the driving spring 166 is connected to the inner wall of the embedding cavity 167.

[0044] The ash hopper 161 replaces the ash collecting chamber 142 to receive and collect the adhesions scraped off the conveying roller 130. When the adhesions collected in the ash hopper 161 tend to be saturated, the driving rod 165 is pressed downward in the vertical direction, and the driving rod 165 is pressed to the positioning block 171, thereby compressing the positioning spring 172. The positioning block 171 is completely embedded in the positioning groove 173, and the driving spring 166 drives the sealing plate 162 to pop out of the embedding cavity 167 and seal the ash opening 163. Then the ash hopper 161 is removed from the ash collecting chamber 142, and the empty ash hopper 161 is installed to continue to receive the adhesions scraped off the conveying roller 130.
