Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a drying device for transfer paper production. Background Technology

[0002] Transfer paper is a medium used to transfer patterns, text, etc., from its surface to other materials (such as fabrics, plastics, metals, etc.). The transfer is usually achieved by means of heating, pressure, or solvents. During the production process, the moisture in the transfer paper needs to be removed to prevent problems such as deformation, mold, and adhesion, and to ensure the stability of the physical and chemical properties of the transfer paper to meet quality requirements and storage and use needs. Microwave drying equipment is usually used for drying transfer paper. During the drying process, the transfer paper is placed on a conveyor and transported to the microwave drying equipment, where it is dried by microwaves.

[0003] During the drying process of transfer paper, a large amount of hot steam is generated. The hot steam is drawn out by the fan and discharged into the air. The discharged hot steam dissipates into the air without utilizing the heat energy in the hot steam, resulting in a waste of the heat energy in the hot steam. Therefore, this application provides a drying device for transfer paper production to meet the needs. Summary of the Invention

[0004] This invention provides a drying device for transfer paper production to solve the problem of wasted thermal energy in hot steam.

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

[0006] A drying apparatus for transfer paper production includes a dryer, which comprises a conveyor and a drying mechanism mounted above the conveyor. The dryer also includes:

[0007] The preheating mechanism includes a housing fixed to the side of the drying mechanism, a number of baffle shells fixed inside the housing, the baffle shells being open at both ends, a preheating head fixed at the transfer paper inlet of the drying mechanism, a fan one being provided at the end of the housing, and a fan two being installed on the housing, the fan two being used to draw in hot steam.

[0008] During the drying of the transfer paper, hot steam flows through the outer wall of the baffle shell under the action of fan two, and air flows inside the baffle shell under the action of fan one. The air exchanges heat with the hot steam at the baffle shell, and the heated air is discharged from the round hole at the bottom of the preheating head. The hot steam after heat exchange is discharged from the air outlet on the side of the shell.

[0009] Preferably, an air inlet shroud is detachably connected to the end of the housing. The air inlet shroud has an air inlet groove corresponding to the baffle shell. A fan is fixed to the end of the air inlet shroud. Air flows from the air inlet groove through the air inlet shroud and into the baffle shell under the action of the fan.

[0010] Preferably, an air outlet shroud is detachably connected to the end of the housing away from the air inlet shroud. The air outlet shroud has an air outlet groove corresponding to the baffle shell. The air in the baffle shell flows through the air outlet groove and into the preheating head.

[0011] Preferably, the bottom of the shell is provided with a collection part, which is used to collect the water generated when hot steam passes through the baffle shell. The bottom of the collection part is provided with a water outlet, and a valve is fixed at the water outlet.

[0012] Preferably, the side of the baffle shell is provided with a through groove, a heat exchange plate is provided in the through groove, a rubber ring is fixed to the side of the heat exchange plate, and the side of the rubber ring is fixed to the inner wall of the through groove.

[0013] Preferably, a connecting assembly is provided inside the baffle shell. The connecting assembly includes connecting blocks fixed on opposite sides of the heat exchange plate, and a connecting strip, which is a rubber strip, is fixed between the two connecting blocks.

[0014] Preferably, the height of the connecting block on the side closer to the heat exchange plate is greater than the height on the side closer to the connecting strip.

[0015] Preferably, the end of the connecting block is provided with a through hole, through which air entering the baffle shell flows.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a shell, a preheating head, and a baffle shell, during the drying of the transfer paper, hot steam flows through the outer wall of the baffle shell under the action of fan two. The heat of the hot steam is transferred to the baffle shell through heat exchange transmission. Air flows inside the baffle shell under the action of fan one. The air exchanges heat with the hot steam at the baffle shell. The heated air is discharged from the round hole at the bottom of the preheating head. After being discharged, the transfer paper is preheated. After the preheated transfer paper enters the drying mechanism, the drying efficiency is higher. The heat energy in the hot steam is effectively utilized and the waste of the heat energy of the hot steam is avoided. The hot steam after heat exchange is discharged from the air outlet opened on the side of the shell. The moisture in the discharged hot steam is treated by the baffle shell, making the discharged hot steam drier and preventing the nearby humid air from affecting the drying efficiency.

[0018] By incorporating connecting components, rubber rings, and heat exchange plates, air flows through the baffle shell. The air passes through the connecting blocks, increasing the contact area between the air and the heat exchange plates, thus improving the heat exchange rate. Furthermore, the airflow causes the connecting blocks to vibrate, which in turn causes the heat exchange plates to vibrate. This vibration allows water on the outside of the heat exchange plates to flow downwards quickly, preventing water from affecting the heat exchange rate between the steam and the heat exchange plates. Additionally, adjacent connecting blocks are connected by rubber strips, ensuring smoother vibration of the adjacent heat exchange plates. Finally, the heat exchange plates vibrate on the side of the baffle shell via rubber rings, further enhancing the smoothness of the vibration. Attached Figure Description

[0029] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0030] The drying apparatus for transfer paper production provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0031] like Figures 1-9 As shown, an embodiment of this utility model provides a drying device for transfer paper production, including a dryer, which consists of a conveyor 1 and a drying mechanism 2. The drying mechanism 2 is installed above the conveyor 1, and further includes:

[0032] The preheating mechanism 3 includes a housing 4 fixed to the side of the drying mechanism 2. The housing 4 is connected to the drying mechanism 2 through a pipe. Several baffle shells 9 are fixed inside the housing 4. The baffle shells 9 are open at both ends. A preheating head 8 is fixed at the transfer paper inlet of the drying mechanism 2. A fan 6 is provided at the end of the housing 4. A fan 16 is installed on the housing 4. The fan 16 is used to draw hot steam.

[0033] During the transfer paper drying process, hot steam flows through the outer wall of the baffle shell 9 under the action of fan 2 16, while air flows inside the baffle shell 9 under the action of fan 1 6. The air exchanges heat with the hot steam at the baffle shell 9, and the heated air exits through the round hole at the bottom of the preheating head 8. The heated steam exits through the air outlet on the side of the shell 4. The shell 4 provides a closed space for heat exchange, preventing heat loss and hot steam leakage. The baffle shell 9 increases the contact area between the hot steam and the air, prolonging the heat exchange time and improving the heat exchange efficiency. Fan 2 16... The hot steam generated by the drying mechanism 2 is drawn into the shell 4 and flows through the outer wall of the baffle shell 9 to achieve heat recovery. The fan 6 drives the air to flow inside the baffle shell 9. After exchanging heat with the hot steam, the heated air is discharged through the bottom round hole of the preheating head 8 to preheat the transfer paper before it enters the drying mechanism 2, shortening the subsequent drying time and improving the overall drying efficiency. At the same time, the hot steam after heat exchange is discharged from the air outlet, reducing the moisture in the hot steam and avoiding the influence of a humid surrounding environment on the drying effect. This achieves efficient utilization of thermal energy and reduces energy waste.

[0034] like Figure 5 As shown in this embodiment, an air inlet hood 5 is detachably connected to the end of the housing 4. The air inlet hood 5 is connected to the housing 4 by bolts. An air inlet slot corresponding to the baffle shell 9 is opened on the air inlet hood 5. A fan 6 is fixed to the end of the air inlet hood 5. Air flows from the air inlet slot through the air inlet hood 5 and enters the baffle shell 9 under the action of the fan 6. The detachable design of the air inlet hood 5 facilitates cleaning and maintenance of internal components. The air inlet slot corresponds to the baffle shell 9 and can guide air to enter each baffle shell 9 precisely, ensuring that each baffle shell 9 has sufficient air for heat exchange and improving the uniformity of heat exchange. The fan 6 is fixed to the end of the air inlet hood 5 and can directly draw external air into the air inlet hood 5 and then distribute it to the baffle shell 9 through the air inlet slot, enhancing the stability and efficiency of air flow and ensuring that the heat exchange process continues stably.

[0035] like Figure 4 As shown in this embodiment, an air outlet hood 7 is detachably connected to the end of the housing 4 away from the air inlet hood 5. The preheating head 8 is connected to the air outlet hood 7 through a pipe. The air outlet hood 7 is connected to the housing 4 through bolts. An air outlet slot corresponding to the baffle shell 9 is opened on the air outlet hood 7. The air in the baffle shell 9 flows through the air outlet slot and into the preheating head 8 after passing through the air outlet hood 7. The detachable design of the air outlet hood 7 also facilitates cleaning and maintenance. The air outlet slot corresponds to the baffle shell 9, which can concentrate and guide the hot air after heat exchange in each baffle shell 9 to the air outlet hood 7, and then send it into the preheating head 8 in a unified manner, avoiding the dispersion and loss of hot air and improving the utilization rate of hot air. The air outlet hood 7 makes the hot air enter the preheating head 8 more orderly, ensuring that the hot air discharged from the preheating head 8 is uniform and stable, thereby uniformly preheating the transfer paper and improving the preheating effect.

[0036] like Figure 3 As shown in this embodiment, a collection section is provided at the bottom of the shell 4. The collection section is used to collect the water generated when hot steam passes through the baffle shell 9. A water outlet is opened at the bottom of the collection section, and a valve is fixed at the water outlet. When hot steam exchanges heat with the baffle shell 9, water droplets will be generated by condensation. The collection section can collect these water droplets in a concentrated manner to prevent water droplets from dripping randomly and affecting the operation of the equipment or causing the hot steam to carry water. This ensures that the hot steam after heat exchange is drier. The water outlet and valve facilitate the periodic discharge of the collected water to avoid excessive water accumulation in the collection section, which would affect the heat exchange efficiency. At the same time, it keeps the inside of the equipment dry and extends the service life of the equipment.

[0037] like Figure 7As shown in this embodiment, a through groove is provided on the side of the baffle shell 9, and a heat exchange plate 11 is arranged in the through groove. A rubber ring 10 is fixed to the side of the heat exchange plate 11. The side of the rubber ring 10 is fixed to the inner wall of the through groove. The rubber ring 10 can seal the gap between the through groove and the heat exchange plate 11 to prevent hot steam or air leakage and ensure the heat exchange effect. On the other hand, the rubber material is elastic, which allows the heat exchange plate 11 to vibrate within a certain range, creating conditions for promoting water droplets to flow down through vibration. At the same time, it reduces the friction between the heat exchange plate 11 and the baffle shell 9 when vibrating, and extends the service life of the components.

[0038] like Figure 8 and Figure 9 As shown in this embodiment, a connecting assembly 12 is provided inside the baffle shell 9. There are several connecting assemblies 12, which are staggered. Each connecting assembly 12 includes a connecting block 13 fixed on the opposite side of the heat exchange plate 11. A connecting strip 14 is fixed between two connecting blocks 13. The connecting strip 14 is a rubber strip. The connecting block 13 can increase the airflow path in the baffle shell 9, prolong the contact time between the air and the heat exchange plate 11, and improve the heat exchange rate. When the air flows through the connecting block 13, it will cause it to vibrate, which in turn will cause the heat exchange plate 11 to vibrate, causing the water droplets on the outside of the heat exchange plate 11 to flow down quickly, avoiding water droplets adhering and affecting heat exchange. The rubber connecting strip 14 has good elasticity and flexibility, which can adapt to the vibration of the connecting block 13 and the heat exchange plate 11, ensuring smooth vibration of adjacent heat exchange plates 11, and enhancing the overall stability of the connecting assembly 12.

[0039] like Figure 9 As shown in this embodiment, the height of the side of the connecting block 13 closest to the heat exchange plate 11 is greater than the height of the side closest to the connecting strip 14. The contact area between the connecting block 13 and the heat exchange plate 11 is larger, resulting in more heat transfer and improved heat exchange efficiency.

[0040] like Figure 9 As shown in this embodiment, the end of the connecting block 13 is provided with a through hole 15. Air entering the baffle shell 9 flows through the through hole 15. The through hole 15 can divert part of the air, so that the air can not only flow on the outside of the connecting block 13, but also pass through the inside of the connecting block 13, thereby improving the heat exchange efficiency.

[0041] Working principle: The transfer paper is conveyed by the conveyor 1, first passing under the preheating head 8 of the preheating mechanism 3, and then entering the drying mechanism 2 for drying. The hot steam generated during the drying process is drawn into the housing 4 by the action of the second fan 16 and flows through the outer wall of the baffle shell 9. At the same time, the first fan 6 draws air into the air inlet hood 5 and enters the baffle shell 9 through the air inlet slot.

[0042] When the air flows inside the baffle shell 9, it exchanges heat with the hot steam outside the shell through the baffle shell 9 and the heat exchange plate 11. The air is heated, and the heated air enters the preheating head 8 through the air outlet hood 7 and is discharged from the bottom round hole to preheat the transfer paper before it enters the drying mechanism 2.

[0043] Water generated during the hot steam heat exchange process is collected at the bottom of the shell 4 and can be discharged through the outlet and valve. When air flows through the connecting block 13 in the baffle shell 9, it drives the connecting block 13 and the heat exchange plate 11 to vibrate, causing the water on the outside of the heat exchange plate 11 to flow down quickly, while improving the heat exchange efficiency. Adjacent heat exchange plates 11 are connected by rubber strips, and the heat exchange plates 11 are connected to the baffle shell 9 by rubber rings 10 to ensure smooth vibration.

[0044] After heat exchange, the hot steam is discharged from the air outlet on the side of the shell 4. At this time, the hot steam is relatively dry. The preheated transfer paper enters the drying mechanism 2 to complete the final drying.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
