Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a split-type paper tube drying room. Background Technology

[0002] In current paper tube drying ovens, the heating devices are installed outside the oven and delivered to the oven through pipes. This not only results in the loss of hot air flow rate and heat, but also causes uneven distribution of hot air flow within the oven, leading to uneven heating of the paper tubes, inconsistent moisture content in different parts of the paper tubes, and deformation of the paper tubes.

[0003] In the prior art, the split-type paper tube drying chamber with publication number CN 118207745 A solves a problem in a previous paper tube drying chamber. This chamber includes a drying chamber, an air-source heat pump, a thermometer, and a hygrometer. It features a built-in open-type heating device, a fresh air supply device with a heat exchanger, an intelligent return air damper, a return air rectifier, and a controller. The built-in open-type heating device includes 1-4 condensers, with 6-24 fans in front of each condenser. The heat exchanger contains adjacent, perpendicular airflow channels made of aluminum foil. High-temperature, high-humidity return air flows from one side of the heat exchanger through the airflow channels and exits from the opposite side. Fresh air flows from another adjacent, perpendicular side of the heat exchanger through the airflow channels and exits from the opposite side. The intelligent return air damper opens and closes according to the temperature and humidity inside the drying chamber at each stage of the paper tube drying process. The advantage of this invention is that it precisely controls the drying process and saves energy.

[0004] However, while this type of paper tube drying oven can improve the uniformity of heat flow within the oven, the return pipe is often directly exposed when the hot air that has exchanged heat with the heat exchanger flows back into the oven. This results in a long contact time between the return pipe and the external space, which can easily lead to the loss of recovered heat. This also results in poor external insulation of the return pipe.

[0005] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a split paper tube drying room. Utility Model Content

[0006] The purpose of this invention is to provide a split-type paper tube drying chamber to solve the problem mentioned in the background art of poor external insulation of the return pipe, which causes the loss of recovered heat.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split paper tube drying oven, including a main operating unit, a drying oven body is provided on one side of the main operating unit, a moisture conveying pipe is provided on the outer wall of the drying oven body, a heat exchanger is fixedly connected to one end of the moisture conveying pipe, a return pipe is connected to the top of the heat exchanger through a fan, a first fan unit is provided inside the drying oven body, and a second fan unit is provided inside the drying oven body.

[0008] Furthermore, the heat exchanger is internally equipped with an aluminum heat exchanger body.

[0012] Furthermore, the surface of the heat dissipation system plate is perforated, and the heat dissipation system plate is located in the middle of the first fan unit and the second fan unit.

[0013] Furthermore, the rotation direction of the first and second fan units is switched and driven by a temperature detection sensor.

[0014] Furthermore, a second mounting block is fixedly connected to the outer wall of the first mounting cover, and a first mounting block is fixedly connected to the outer wall of the second mounting cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1.

[0030] 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. Example

[0031] like Figures 1-7 As shown, the split paper tube drying oven includes a main operating unit 1, a drying oven body 2 is provided on one side of the main operating unit 1, and a moisture conveying pipe 3 is provided on each of the two outer walls of the drying oven body 2, which communicates with the interior of the drying oven body. The moisture conveying pipe 3 is connected to a heat exchanger 4, and an aluminum heat exchanger body 5 is provided inside the heat exchanger 4. A first fan unit 8 is provided inside the drying oven body 2, a second fan unit 9 is provided inside the drying oven body 2, and a temperature detection sensor 13 is provided inside the drying oven body 2. The temperature detection sensor 13 is existing technology and will not be described or shown in detail here.

[0032] During use, the heat exchanger 4 draws in cold air from the outside and air that has been circulated inside the drying chamber and heats it. At the same time, it circulates into the drying chamber, and the air drawn in from inside the drying chamber can also be dehumidified.

[0033] Specifically, such as Figure 4 As shown, the outer wall of the heat exchanger 4 is provided with a connecting pipe 6 for the entry of outside air. The top of the heat exchanger 4 is connected to a return pipe 7 via a fan. The air outlet of the return pipe 7 is split to the first pipe port 71 and the second pipe port 72 and is located on one side of the first fan group 8 and the second fan group 9, respectively.

[0034] It should be noted that a heat dissipation system plate 12 is provided between adjacent fan units. The surface of the heat dissipation system plate 12 is hollowed out. The heat dissipation system plate 12 is located in the middle of the first fan unit 8 and the second fan unit 9. The hollowed-out surface of the heat dissipation system plate 12 plays a role in the circulation and return of heat. It is beneficial to achieve the effect of convenient heat flow and transportation by placing the heat dissipation system plate 12 in the middle of the first fan unit 8 and the second fan unit 9.

[0035] On the other side of the two sets of fan units, there are a first conveying channel 10 and a second conveying channel 11 for placing the materials to be dried. The ends of the two conveying channels are connected and separated by a partition.

[0036] In use, outside air is dehumidified and heated through the inside of the connecting pipe 6 on the heat exchanger 4, and enters the drying room through the return pipe 7, that is, one side of the first fan unit 8 and the second fan unit 9. In this embodiment, an air valve is provided on each of the two pipe openings after the return pipe 7 is split, and only one of the two air valves can be opened at the same time.

[0037] As attached Figure 5 As shown, when the hot air discharged from the heat exchanger 4 is blown out from the first port 71, the air valve on the second port 72 is closed. The hot air will then enter the air inlet of the second fan unit 9 through the heat dissipation system plate 12. At this time, the second fan unit 9 starts and begins to suck in the hot air and send it out towards the second conveying channel 11. The airflow of the first fan unit 8 and the second fan unit 8 is opposite, which will generate suction on the hot air blown out by the second fan unit 9. The hot air returns to the rear side of the second fan unit 9 after passing through the heat dissipation system plate 12.

[0038] It should be noted that, in addition to the outside air, the air inlet of the heat exchanger 4 also draws in the hot air circulating from the first fan unit 8 and the second fan unit 8 through the moisture delivery pipe 3 into the heat exchanger 4 for dehumidification. The treated air still has a certain temperature, thereby reducing the time required to heat the outside cold air.

[0039] Below the moisture delivery pipes 3 on both sides of the drying chamber body 1, there are also a first air inlet 24 and a second air inlet 25. Specifically, the first air inlet 24 is connected to the space where the second fan unit 9 is located, and the second air inlet 25 is connected to the space where the second fan unit 9 is located.

[0040] When the air valve on the first pipe 71 is opened, the first air port 24 located in the space of the second fan unit 9 will also be opened, drawing the hot air that has been circulating inside the drying room for a period of time into the heat exchanger 4 for dehumidification.

[0041] And reference appendix Figure 6At this time, the rotation direction of the first fan unit 8 and the second fan unit 9 changes. At the same time, the air valve on the first pipe port 71 is closed and the air valve on the second pipe port 72 is opened. Simultaneously, the first air port 24 is closed and the second air port 25 is opened, which is completely opposite to the hot air flow direction mentioned above. The flow process will not be described in detail here.

[0042] like Figure 4 and Figure 5 As shown, the rotation direction of the first fan unit 8 and the second fan unit 9 is controlled by the central controller in the main unit 1, while the temperature inside the drying chamber is sensed by the temperature detection sensor 13. After running for a period of time or reaching a certain temperature, the central controller will control the fan units to reverse to change the airflow direction.

[0043] like Figure 6 As shown, in order to insulate the distribution pipe 7 through which the hot air flows, a second mounting block 18 is fixedly connected to the outer wall of the first mounting cover 14, and a first mounting block 17 is fixedly connected to the outer wall of the second mounting cover 15. A rotating rod 19 is threadedly connected to the outer wall of the first mounting block 17, and a positioning plate 22 that is inserted into the outer wall of the second mounting block 18 is fixedly connected to one end of the rotating rod 19. This facilitates the easy engagement and installation of the first mounting cover 14 and the second mounting cover 15 through the setting of the positioning plate 22. When the insulation sleeve 16 is fitted onto the outer wall of the return pipe 7 for insulation treatment, in order to improve the stability of the insulation sleeve 16 on the outer wall of the return pipe 7, the positioning plate 22 is inserted into the inner wall of the connecting groove 23, and the rotating rod 19 is rotated and connected by the threads of the outer spiral 20 and the inner spiral 21, so that the cross-section of the positioning plate 22 and the connecting groove 23 are perpendicular to each other, thereby achieving the effect of engaging and connecting the insulation sleeve 16 on the outer wall of the return pipe 7.

[0044] like Figure 7 As shown, the outer wall of the rotating rod 19 is provided with an outer spiral 20, and the inner wall of the second mounting block 18 is provided with an inner spiral 21 at the connection between the outer spiral 20 and the inner wall. This facilitates the convenient adjustment of the positioning plate 22's usage status through the setting of the inner spiral 21 and the outer spiral 20.

[0045] like Figure 8 As shown, a connecting groove 23 is provided at the connection between the outer wall of the second mounting block 18 and the positioning plate 22. The length of the connecting groove 23 is greater than the length of the positioning plate 22, and the length of the positioning plate 22 is greater than the width of the connecting groove 23. This arrangement of the connecting groove 23 at the connection between the outer wall of the second mounting block 18 and the positioning plate 22 makes the cross-sections of the positioning plate 22 and the connecting groove 23 perpendicular to each other, thus achieving the effect of the insulation sleeve 16 being snapped into place on the outer wall of the return pipe 7.

[0046] When using this split paper tube drying oven, firstly, when drying products through the drying oven, in order to improve the uniformity of heat flow inside the drying oven and the heat preservation effect of the return pipe 7 during heat return transport, and to prevent heat loss and large losses, after the temperature detection sensor 13 detects that the temperature difference value of the conveying channel exceeds the preset value, the temperature detection sensor 13 transmits the signal to the first fan unit 8 and the second fan unit 9, so that the conveying path of the fan unit is changed, thereby changing the direction of hot air in the conveying channel and improving the heat uniformity inside the drying oven.

[0047] Finally, when the insulation sleeve 16 is fitted onto the outer wall of the return pipe 7 for insulation treatment, in order to improve the stability of the insulation sleeve 16 on the outer wall of the return pipe 7, the positioning plate 22 is inserted into the inner wall of the connecting groove 23, and the rotating rod 19 is rotated and connected by the threads of the outer spiral 20 and the inner spiral 21, so that the cross-section of the positioning plate 22 and the connecting groove 23 are perpendicular to each other, so as to achieve the effect of the insulation sleeve 16 being snapped onto the outer wall of the return pipe 7.

[0048] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
