Description

Technical Field

[0001] This utility model relates to the field of heat insulation strip processing, and in particular to a drying device for producing honeycomb heat insulation strips. Background Technology

[0002] Honeycomb thermal insulation strips are a widely used thermal insulation material in construction, industry and other fields. They have many advantages such as light weight and excellent thermal insulation performance. During their production process, after extrusion molding and other processes, the thermal insulation strips often contain a certain amount of moisture. The presence of moisture will affect the physical properties, dimensional stability and subsequent use effect of the thermal insulation strips. Therefore, they need to be dried to ensure that the products meet quality standards and meet the requirements of thermal insulation and structural stability in practical applications.

[0003] Common methods include natural air drying and the use of traditional hot air drying equipment. Natural air drying involves placing the formed insulation strips in a well-ventilated, well-lit area, relying on the natural air circulation and heat to slowly evaporate the moisture in the insulation strips. Traditional hot air drying equipment is usually set up in a relatively enclosed space, with a heating device to generate hot air, which is then delivered to the area where the insulation strips are placed through simple air outlets. The hot air circulates within the space, carrying away the moisture. Some equipment is also equipped with fans to accelerate air circulation and increase the drying speed.

[0004] The existing technology has the following drawbacks: Although traditional hot air drying equipment can speed up the drying process to a certain extent, it often suffers from uneven hot air distribution, which leads to uneven heating of the insulation strips during the drying process. This can result in some areas being over-dried while others still retain a lot of moisture, affecting the overall quality of the product. Therefore, a drying device for the production of honeycomb insulation strips is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drying device for the production of honeycomb insulation strips, which aims to improve the problem of uneven drying of insulation strips in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for producing honeycomb insulation strips, comprising a drying barrel, a heating box at the top of the drying barrel, a three-way pipe at the bottom of the heating box, a motor on the side wall of the drying barrel, a gear shaft fixedly connected to the output end of the motor, a gear ring meshing with the outer wall of the gear shaft, a fixed ring fixedly connected to the inner wall of the drying barrel, a rotating ring rotatably connected to the inner wall of the fixed ring, a fixed frame fixedly connected to the inner wall of the right end of the drying barrel, a movable plate slidably connected to the inner wall of the fixed frame, a moving mechanism at the top of the movable plate, multiple sets of rotating rings connected to each other by connecting rods, and a circulation component at the top of the drying barrel;

[0007] The moving mechanism includes a placement frame, which is slidably connected to the top of the moving plate. The bottom of the placement frame is elastically connected to the moving plate via a return spring. A pressing block is fixedly connected to the side wall of the placement frame.

[0008] As a further description of the above technical solution:

[0009] The circulation assembly includes a processing box, which is located at the top of the drying barrel. The inner wall of the processing box is provided with an adsorption plate, and a circulating fan is located at the top of the processing box. One end of a conveying pipe is fixedly connected to the top of the circulating fan, and the other end of the conveying pipe is fixedly connected to the side wall of the drying barrel.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the placement frame is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the top end of the moving plate.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the gear shaft is in contact with the outer wall of the extrusion block.

[0014] As a further description of the above technical solution:

[0015] The gear shaft is rotatably connected to the inner wall of the drying barrel.

[0016] As a further description of the above technical solution:

[0017] The three-way pipe is fixed to the top of the fixed ring and passes through the inner wall of the drying barrel.

[0018] As a further description of the above technical solution:

[0019] The toothed ring is fixedly connected to the side wall of the rotating ring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the gear shaft is driven by a motor to rotate, which in turn drives the rotating ring to achieve multi-angle air outlet. In conjunction with the protrusion of the gear shaft to squeeze the squeezing block, the placement frame vibrates and causes the heat insulation strip to flip, which effectively avoids uneven heating of the heat insulation strip and ensures that all parts are heated evenly, thus guaranteeing the drying quality.

[0022] 2. In this utility model, after water vapor is adsorbed by the adsorption plate, it can be sent back to the drying barrel by the circulating fan through the conveying pipe to form a closed loop. This not only realizes the reuse of hot air and reduces energy consumption, but also continuously creates a drying environment and improves drying efficiency. Attached Figure Description

[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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a drying device for producing honeycomb-type heat insulation strips, including a drying barrel 1. A sealed door is located at the left end of the drying barrel 1, which can be opened or closed during use. A heating chamber 2 is located at the top of the drying barrel 1, containing a fan and heating wire. The fan transfers the heat generated by the heating wire to a three-way pipe 3, which is conventional technology and will not be elaborated further. A three-way pipe 3, consisting of three pipes connected by three fixing rings 6, is located at the bottom of the heating chamber 2. A motor 4 is located on the side wall of the drying barrel 1, with a gear shaft 5 fixedly connected to the output end of the motor 4. The left end of the gear shaft 5 is a gear, which rotates the gear ring 8. The outer wall of the gear shaft 5 has protrusions that can press against the pressing block 13 to generate heat. The moving plate 10 is connected to the inner wall of the gear shaft 5 with a gear ring 8. A fixed ring 6 is fixedly connected to the inner wall of the drying barrel 1. A rotating ring 7 is rotatably connected to the inner wall of the fixed ring 6. The rotating ring 7 and the fixed ring 6 are sealed at the rotation point using existing sealing technology, so there will be no leakage. A fixed frame 9 is fixedly connected to the inner wall of the right end of the drying barrel 1. The fixed frame 9 mainly supports and connects the entire moving plate 10. The moving plate 10 is slidably connected to the inner wall of the fixed frame 9. The middle part of the moving plate 10 is hollow, so it will not affect the air circulation. A moving mechanism is provided at the top of the moving plate 10. Multiple sets of rotating rings 7 are provided. The multiple sets of rotating rings 7 are connected by a connecting rod 14. The connecting rod 14 can make the multiple sets of rotating rings 7 rotate synchronously. An air outlet is provided on the rotating ring 7, which allows hot air to be delivered into the drying barrel 1 from the air outlet. A circulation component is provided at the top of the drying barrel 1.

[0032] The moving mechanism includes a placement frame 12, which is slidably connected to the top of the moving plate 10. The moving plate 10 has guide posts that allow the placement frame 12 to slide up and down on the guide posts. The bottom end of the placement frame 12 is elastically connected to the moving plate 10 via a return spring 11. A pressing block 13 is fixedly connected to the side wall of the placement frame 12. The pressing block 13 is inclined, and when the inclined surface is pressed, it will cause the pressing block 13 to move vertically.

[0033] Reference Figure 1 and Figure 5The circulation assembly includes a processing box 15, which is located at the top of the drying barrel 1. The processing box 15 has a pipe connected to the drying barrel 1, allowing steam to enter the processing box 15. The inner wall of the processing box 15 is provided with an adsorption plate 17, which is an existing activated carbon fiber plate. Activated carbon fiber has a highly developed microporous structure and a large specific surface area, which can adsorb water vapor molecules on its microporous surface through physical adsorption by relying on the van der Waals forces between molecules. A circulating fan 16 is provided at the top of the processing box 15, which can transfer the hot air in the processing box 15 to the conveying pipe 18. One end of the conveying pipe 18 is fixedly connected to the top of the circulating fan 16. The conveying pipe 18 is an existing heat-insulated pipe that can maintain the temperature of the gas. The other end of the conveying pipe 18 is fixedly connected to the side wall of the drying barrel 1.

[0034] Reference Figures 2-4 The bottom end of the placement frame 12 is fixedly connected to one end of the return spring 11. When the placement frame 12 moves downward, it will compress the return spring 11. When resetting, the elastic force of the return spring 11 will carry the placement frame 12 back to its original position. The other end of the return spring 11 is fixedly connected to the top end of the moving plate 10. The outer wall of the gear shaft 5 is in contact with the outer wall of the extrusion block 13. The gear shaft 5 is rotatably connected to the inner wall of the drying barrel 1. The three-way pipe 3 is fixedly connected to the top end of the fixed ring 6. The three-way pipe 3 and the fixed ring 6 are connected to each other, which can allow hot air to enter the fixed ring 6. The three-way pipe 3 passes through the inner wall of the drying barrel 1. There is a sealing material at the connection between the drying barrel 1 and the three-way pipe 3 to ensure that heat will not leak. The gear ring 8 is fixedly connected to the side wall of the rotating ring 7.

[0035] Working principle: When the heat insulation strip needs to be dried, simply place it on the placement frame 12, then start the equipment in the heating chamber 2. The hot air generated by the equipment enters the fixed ring 6 through the three-way pipe 3 and is transferred to the rotating ring 7. The hot air is sprayed from the air outlet of the rotating ring 7 onto the heat insulation strip in the drying barrel 1. At the same time, start the motor 4, which drives the gear shaft 5 to rotate. The gear shaft 5 drives the meshing gear ring 8 to rotate. The gear ring 8 drives the rotating ring 7 through the connecting rod 14, causing multiple rotating rings 7 to rotate. The hot air is blown onto the heat insulation strip from the air outlet of the rotating ring 7 at multiple angles. When the gear shaft 5 rotates, the protrusions on its outer wall periodically press the inclined surface of the extrusion block 13, forcing the placement frame 12 to compress the return spring 11 downward. When the protrusions leave the extrusion block 13, the placement frame 12 returns to its original position under the action of the spring force. This process causes the placement frame 12 to vibrate up and down, causing the heat insulation strip to flip, ensuring that all parts are heated evenly.

[0036] Hot air flows inside the drying barrel 1, carrying away moisture from the surface of the insulation strip, forming humid hot air. The humid hot air rises to the top of the drying barrel 1 and enters the processing chamber 15 through the pipe. The water vapor in the humid hot air is adsorbed by the microporous structure of the adsorption plate 17. The dried hot air is then sent back to the drying barrel 1 by the circulating fan 16 through the conveying pipe 18, forming a closed loop circulation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
