Description

Technical Field

[0001] This invention relates to the field of impregnation and drying equipment, specifically to an integrated impregnation and drying device for impregnated paper. Background Technology

[0002] Impregnated paper refers to a special type of paper that has been soaked in a specific chemical liquid, giving it properties such as water resistance, fire resistance, and corrosion resistance. Impregnated paper can be used for decorative work. The production process of impregnated paper requires an impregnation machine to complete the impregnation of the paper. A typical impregnation machine includes a feeding device, an impregnation device, an impregnation storage device, and a discharging device. To prevent wrinkles from forming after impregnation, existing impregnation machines also include a drying device between the impregnation and discharging devices, forming an integrated impregnation and drying system to complete the impregnation and drying of the paper. Drying devices are generally divided into vertical and horizontal types. A typical horizontal drying device consists of a long, narrow oven that uses high-temperature gas to quickly dry the impregnated paper.

[0003] For example, patent CN107988847B discloses a horizontal impregnation and drying machine for decorative paper production, including a base paper roll, an impregnation mechanism, a drying mechanism, and a receiving roller. The impregnation mechanism includes an impregnation tank, an impregnation cover, a stirring mechanism, an impregnation roller, and a storage tank. The impregnation tank has an isosceles trapezoidal cross-section, and a retaining ring is provided above the impregnation tank. The impregnation cover is fixed on the retaining ring, and a glue injection cavity is provided inside the retaining ring. The storage tank is connected to the glue injection cavity through a glue injection pipe. A glue injection channel is provided on the retaining ring, and the glue injection channel is connected to the impregnation tank. A one-way valve is provided on the glue injection pipe. The impregnation roller is rotatably fixed in the impregnation tank through a rotating shaft. The stirring mechanism includes a cylinder and a stirring wheel. The stirring wheel includes a connecting main shaft, a fixed frame, and stirring blades. This design ensures the quality of the impregnated paper, guarantees uniform glue coating, prevents breakage, reduces costs, minimizes waste, and improves efficiency.

[0004] Although the impregnation dryer described in the aforementioned patent can ensure the quality of impregnated paper, guarantee uniform glue application, and prevent breakage, existing impregnation dryers have several drawbacks. If the humid gas from the dried impregnated paper is directly discharged from the oven, the liquid in the humid gas will emit an unpleasant odor in the air, potentially posing a threat to the environment and the health of workers. If the humid gas is left inside the oven for recycling, the existing impregnation dryer cannot remove the liquid from the humid gas. When the humid gas is used to dry subsequent impregnated paper, it will cause secondary water soaking, resulting in a decrease in the drying effect of the impregnated paper and a reduction in the production efficiency of impregnated paper. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated impregnation and drying device for impregnated paper, thereby solving the problems mentioned in the background art and enabling the impregnation dryer to purify the generated humid gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated impregnation and drying equipment for impregnated paper, comprising a support frame and an impregnation device, a discharge device, and a drying device connected to the support frame. The drying device includes multiple drying chambers, an air inlet assembly, a heating assembly, an air outlet assembly, a drain pipe, and a control box. A drying chamber is provided inside the drying chamber. Two movable rollers are fixedly connected to the two ends of the inner walls on both sides of the drying chamber.

[0007] Furthermore, the air intake assembly includes an air intake box, a fan, and an air intake pipe. An air intake cavity is opened inside the air intake box. The air intake box is fixedly connected to one side of the drying box. Multiple fans are fixedly connected to the side of the drying box located inside the air intake cavity. Multiple air inlets penetrating the air intake box are opened on the top surface of the air intake cavity. Air intake pipes are fixedly connected to the air inlets. The air intake pipes are fixedly connected to the heating assembly. Multiple air inlets corresponding to the fan positions are opened on one side of the drying box.

[0008] Furthermore, the heating assembly includes a heating box, heating units, and connecting blocks. The heating box is fixedly connected to the drying box. A heating chamber is provided inside the heating box, and multiple heating units are fixedly connected inside the heating chamber. Each heating unit includes two connecting plates and multiple heating wires. Both ends of the heating wires are fixedly connected to the connecting plates, and both ends of the connecting plates are fixedly connected to the inner wall of the heating chamber. Multiple connecting blocks corresponding to the positions of the air inlet pipes are fixedly connected to the side of the heating box near the air inlet box. Air guide grooves communicating with the heating chamber and the air inlet pipes are provided inside the connecting blocks. Multiple condenser pipes are fixedly connected to the top of the side of the heating box away from the connecting blocks, and the condenser pipes are connected to the heating chamber.

A drain pipe is fixedly connected to the bottom of one side of the air outlet box and is connected to the drain tank.

[0010] Furthermore, the liquid collection tank is designed in an inverted cone shape, with the lowest point of the liquid collection tank located at the drain tank.

[0011] Furthermore, baffles are fixedly connected to the openings on both sides of the drying chamber, and a feed inlet is opened in the middle of the baffle, which corresponds to the position of the moving roller.

[0012] Furthermore, buffer pads are fixedly connected to the four corners of the fan, with one side of the buffer pads adhering to the surface of the drying oven.

[0013] Furthermore, a fixing plate is fixedly connected to the middle of the condenser tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This integrated impregnation and drying equipment for impregnated paper uses a condenser pipe installed between the air outlet component and the heating component, and a drain pipe installed at the bottom of the air outlet component.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Please see Figure 1-10 An integrated impregnation and drying device for impregnated paper includes a support frame 1 and an impregnation device 2, a discharge device 3 and a drying device connected to the support frame 1. The drying device includes multiple drying chambers 4, an air inlet assembly, a heating assembly, an air outlet assembly, a drain pipe 26 and a control box 30. A drying chamber 5 is opened in the drying chamber 4. Two movable rollers 6 are fixedly connected to the two ends of the inner walls on both sides of the drying chamber 5. The air inlet assembly and the air outlet assembly are fixedly connected to the two sides of the drying chamber 4 respectively. The heating assembly is fixedly connected to the surface of the drying chamber 4. Multiple condenser pipes 22 are fixedly connected between the heating assembly and the air outlet assembly. The condenser pipes 22 are inclined. A drain pipe 26 is fixedly connected to the bottom of the air outlet assembly. The drying chambers 4 are arranged in a staggered arrangement.

[0019] like Figure 1As shown, compared to the horizontal impregnation and drying machine for decorative paper production disclosed in patent CN107988847B, the main improvement of this invention is that it enables the impregnation and drying machine to purify the generated humid gas. In the integrated impregnation and drying equipment for impregnated paper in this invention, after the impregnation and drying process, the impregnated paper, after being impregnated in the impregnation device 2, enters the drying chamber along the moving roller 6. At this time, the heating component generates hot air and introduces it into the air inlet component. The air inlet component then introduces the hot air into the drying chamber 5. Under the action of the air inlet and air outlet components, the hot air moves along the direction from the air inlet component to the air outlet component, thereby achieving the drying of the upper and lower surfaces of the impregnated paper. After drying, the hot air becomes humid air and enters the air outlet component. The humid air undergoes its first cooling in the air outlet component, and the liquid generated during the cooling process remains in the air outlet component. The humid air then enters the condenser 22, where the temperature of the humid air decreases, resulting in secondary condensation and becoming dry air. The liquid generated during the secondary condensation process flows back to the air outlet assembly along the condenser pipe 22. Subsequently, the liquid generated from the two condensations is discharged to the external collection device through the drain pipe 26. The dry air enters the heating assembly through the condenser pipe 22, thus realizing the recycling of hot air. The inclined arrangement of the condenser pipe 22 ensures that the condensed liquid flows back to the air outlet assembly stably. At the same time, since the dry air still has a certain temperature, the waste heat of the dry air is recovered and utilized, improving energy utilization and reducing energy consumption. The alternating arrangement of the drying box 4 ensures uniform drying of both sides of the impregnated paper, preventing uneven drying and wrinkles. The condenser pipe 22 can increase the contact area between the humid air and the outside environment, accelerate the temperature drop of the humid air, and improve condensation efficiency. It is worth noting that the structure of the impregnation device 2 and the discharge device 3 in this invention is similar to the structure of the horizontal impregnation dryer for decorative paper production disclosed in patent publication number CN107988847B, so it will not be described in detail here.

[0020] By installing a condenser pipe 22 between the air outlet assembly and the heating assembly, and a drain pipe 26 at the bottom of the air outlet assembly, the condenser pipe 22 is used to condense the humid air, thereby separating the liquid from the air in the humid air. This achieves the purification and recycling of the humid air, thereby reducing the possibility of secondary water immersion in the impregnated paper, avoiding the potential threat of humid air to the environment and the health of workers, improving the drying effect and efficiency of the impregnation dryer, and thus increasing the production efficiency of the impregnated paper.

[0021] As a preferred embodiment of the present invention, the air intake assembly includes an air intake box 7, a fan 9, and an air intake pipe 20. An air intake cavity 8 is provided inside the air intake box 7. The air intake box 7 is fixedly connected to one side of the drying chamber 4. Multiple fans 9 are fixedly connected to one side of the drying chamber 4 located inside the air intake cavity 8. Multiple air inlets 21 penetrating the air intake box 7 are provided on the top surface of the air intake cavity 8. The air inlets 21 are fixedly connected to the air intake pipe 20. The air intake pipe 20 is fixedly connected to the heating assembly. Multiple air inlets 10 corresponding to the positions of the fans 9 are provided on one side of the drying chamber 4.

[0022] Specifically, the hot air generated by the heating component enters the air inlet chamber 8 through the air inlet pipe 20 and air inlet 21. Then, under the action of the fan 9, it is drawn into the drying chamber 5 to achieve the drying function of the impregnated paper. The fan 9 can transform the hot air into a high-speed hot air flow, which can quickly remove the liquid on the surface of the impregnated paper, improve the drying efficiency of the impregnated paper, and prevent the hot air that carries away the liquid from staying around the impregnated paper for a long time, causing secondary pollution to the impregnated paper.

[0023] As a preferred embodiment of the present invention, the heating assembly includes a heating box 14, heating units, and connecting blocks 18. The heating box 14 is fixedly connected to the drying box 4. A heating chamber 15 is provided inside the heating box 14. Multiple heating units are fixedly connected inside the heating chamber 15. Each heating unit includes two connecting plates 16 and multiple heating wires 17. The two ends of the heating wires 17 are fixedly connected to the connecting plates 16 respectively. The upper and lower ends of the connecting plates 16 are fixedly connected to the inner wall of the heating chamber 15. Multiple connecting blocks 18 corresponding to the positions of the air inlet pipes 20 are fixedly connected to the side of the heating box 14 near the air inlet box 7. An air guide groove 19 communicating with the heating chamber 15 and the air inlet pipes 20 is provided inside the connecting blocks 18. Multiple condenser pipes 22 are fixedly connected to the top of the side of the heating box 14 away from the connecting blocks 18. The condenser pipes 22 are connected to the heating chamber 15.

[0024] Specifically, the dry air after secondary condensation enters the heating chamber 15 through the condenser pipe 22, and then passes through the heating wire 17, which heats the dry air, raising its temperature and turning it into hot air. The design of multiple heating units enables multiple heating of the dry air, ensuring that the dry air reaches the temperature required for drying, reducing the time required for the dry air to heat up, and facilitating the recycling of the dry air, making the circulation process smoother.

A drain pipe 26 is fixedly connected to the bottom of one side of the air outlet box 11. The drain pipe 26 is connected to the drain tank 25.

[0026] Specifically, humid air is drawn into the air outlet 13 by the fan 9 and then into the air outlet cavity 12, where it undergoes initial condensation. The condensate produced during the two condensation processes falls into the collection tank 24 and is then discharged through the drain pipe 26. This design achieves the collection and recycling of condensate, effectively preventing pollution and odor generation, and maintaining a clean and comfortable workplace.

[0027] As a preferred embodiment of the present invention, the liquid collection tank 24 is configured in an inverted cone shape, and the lowest point of the liquid collection tank 24 is located at the drain tank 25.

[0028] Specifically, the inverted cone-shaped liquid collection tank 24 can guide the condensate to flow along the inclined surface and naturally collect at the drain tank 25. This can effectively collect the condensate and prevent it from spreading in the air outlet chamber 12. This design can maximize the discharge efficiency of the condensate and avoid water leakage caused by accumulation.

[0029] As a preferred technical solution of the present invention, baffle plates 28 are fixedly connected to the openings on both sides of the drying chamber 5, and a feed inlet 29 is provided in the middle of the baffle plate 28, which corresponds to the position of the moving roller 6.

[0030] Specifically, the baffle 28 can effectively block humid air from entering the workplace, thereby reducing the humidity in the workplace, improving the comfort of workers, reducing the corrosion of equipment and parts in the workplace, and improving the recovery rate of liquids. The baffle 28 can be fixedly connected to the drying chamber 4 by welding, bolting, snap-fitting, etc. The preferred method is to use detachable connection such as bolting or snap-fitting, which can facilitate the disassembly of the baffle 28 for maintenance by workers. The baffle 28 can be made of glass, which makes it convenient for workers to observe the drying process in the drying chamber 5.

[0033] As a preferred technical solution of the present invention, a plurality of fixing plates 27 are fixedly connected to the outer wall of the condenser tube 22.

The fixing rod 35 is fixedly connected to the surface of the drying oven 4.

[0034] Specifically, the cooperation of the fixing plate 27, the connecting rod 34 and the fixing rod 35 can provide fixation and support for the condenser tube 22, preventing the middle of the condenser tube 22 from bending downwards and causing the liquid to not flow smoothly into the air outlet cavity 12; the fixing rod 35 is fixed to the drying box 4 and the fixing plate 27 by welding, and the connecting rod 34 is fixed to the fixing plate 27 by bolts or welding.

[0036] Specifically, the upward-convex pipe in the middle of the U-shaped tube 32 can provide a barrier for the liquid in the condenser tube 22, preventing the air in the condenser tube 22 from carrying the liquid into the heating chamber 15 and causing faults such as short circuits, and further improving the separation between air and liquid; the U-shaped tube 32 and the condenser tube 22 are integrally formed.
