Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery processing of stenter machines, and in particular to a heat exchange device for waste heat recovery of stenter machines. Background Technology

[0002] The fundamental function of waste heat recovery from stenters is to turn waste into treasure. It effectively recovers the heat energy that was originally directly emitted into the atmosphere and wasted, and then reuses it in the production process or other processes that require heat, thus realizing the cascade utilization of energy. This measure effectively reduces the exhaust temperature and reduces the problem of excessively high workshop temperature caused by high-temperature exhaust gas emissions, creating a more comfortable and healthier working environment for workers.

[0003] However, the existing heat exchange device for waste heat recovery of stenters still has some problems in practical use: during the process of recovering the hot air discharged from the stenter, particulate impurities will be mixed in with the hot air. If these particulate impurities are not treated, they will gradually accumulate inside the heat exchange device, resulting in a decrease in heat exchange efficiency, and may even block the pipes, affecting the normal operation of the equipment. In addition, the accumulation of impurities will also increase the maintenance frequency and cost of the equipment and reduce its overall service life. Summary of the Invention

[0004] This invention provides a heat exchange device for waste heat recovery from a stenter, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat exchange device for waste heat recovery in a stenter includes an impurity particle blocking mechanism, a discharge pipe, and a storage tank. The impurity particle blocking mechanism includes a collection box with a rectangular groove in the middle of the upper end. Both sides of the inner wall of the rectangular groove are slidably connected to baffles via sliding grooves. A toggle rod is fixedly connected to the middle of the upper end of the baffles. Adjusting blocks are fixedly connected to both sides of the lower end of the toggle rod. Particle filtering perforated plates are slidably connected to both ends of the adjusting blocks. A support shaft is rotatably connected to one end of the particle filtering perforated plates.

[0006] As a further improvement to this technical solution: one side of the back of the collection box is fixedly connected to one end of the discharge pipe through a through hole, the lower end of the support shaft is fixedly connected to one side of the bottom wall of the collection box, and a mounting bolt is threadedly connected to one side of the collection box through a through hole, and a sealing plate is slidably connected to the surface of the mounting bolt.

[0007] As a further improvement to this technical solution: a hot gas inlet pipe is fixedly connected to the bottom of the surface of the storage tank through a through hole, and an outlet pipe is fixedly connected to the middle of the upper end of the storage tank through a through hole. A blower is fixedly connected to one end of the outlet pipe, and the output end of the blower is fixedly connected to the other end of the outlet pipe.

[0008] As a further improvement to this technical solution: a double-through pipe is fixedly connected to one side of the collection box through a through hole, a blower is fixedly connected to the other end of the double-through pipe, a discharge pipe II is fixedly connected to the output end of the blower, a heat insulation plate is fixedly connected to the surface of the discharge pipe II, and a storage tank II is fixedly connected to the surface of the heat insulation plate.

[0009] As a further improvement to this technical solution: the top of the second surface of the storage tank is fixedly connected to one side of the surface of the double-through pipe through a through hole, and a reinforcing plate is fixedly connected to the middle of the surface of the double-through pipe.

[0010] As a further improvement to this technical solution: a support base is fixedly connected to the lower end of the storage tank one, and a back reinforcement bracket is fixedly connected to both sides of the upper end of the support base near the back. One end of the back reinforcement bracket is fixedly connected to the middle of the surface of the storage tank one and the storage tank two respectively.

[0011] As a further improvement to this technical solution: a bottom support rod is fixedly connected to the upper end of the support base near the middle, and the upper end of the bottom support rod is fixedly connected to the lower end of the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a particle blocking mechanism and a storage tank, the particle filter plate can adjust its tilt angle, which effectively changes the direction and speed of the airflow. This allows impurities to be more evenly distributed across the entire surface of the particle filter plate, ensuring that it can fully utilize its filtration efficiency. Before entering the heat exchange stage, the particle filter plate removes most of the pollutants, thereby improving the overall filtration effect and stability.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0017] Please see Figures 1-5In this embodiment of the present invention, a heat exchange device for waste heat recovery of a stenter includes an impurity particle blocking mechanism 1, a discharge pipe 2, and a storage tank 3. The impurity particle blocking mechanism 1 includes a collection box 101. A rectangular groove 102 is provided in the middle of the upper end of the collection box 101. Both sides of the inner wall of the rectangular groove 102 are slidably connected to a baffle plate 103 through a sliding groove. A toggle rod 104 is fixedly connected to the middle of the upper end of the baffle plate 103. Adjusting blocks 105 are fixedly connected to both sides of the lower end of the toggle rod 104. Both ends of the adjusting block 105 are slidably connected to a particle filter plate 106. One end of the particle filter plate 106 is rotatably connected to a support shaft 107.

[0018] The inner wall of the collection box 101 and the bottom of the baffle plate 103 are filled with ceramic fiber cotton to increase the heat insulation performance. The rectangular groove 102 is covered by the baffle plate 103. The baffle plate 103 fits tightly against the inner top wall of the collection box 101 to ensure that heat does not escape from the gaps.

[0019] The top and bottom of the particle filter plate 106 are provided with sliding grooves that are adapted to one end of the adjusting block 105. Space is reserved between the two particle filter plates 106 so that when the particle filter plate 106 is rotated by the toggle rod 104, the adjusting block 105 not only limits the particle filter plate 106, but also ensures that the particle filter plate 106 maintains a stable movement trajectory during the rotation. This design effectively avoids jamming or misalignment caused by angle changes, thereby improving the reliability of the overall structure.

[0020] Please see Figure 1 , 4 One side of the back of the collection box 101 is fixedly connected to one end of the discharge pipe 2 through a through hole. The lower end of the support shaft 107 is fixedly connected to one side of the inner bottom wall of the collection box 101. One side of the collection box 101 is threadedly connected to the mounting bolt 4 through a through hole. The surface of the mounting bolt 4 is slidably connected to the sealing plate 5.

[0021] The gap between the discharge pipe 2 and the storage tank 3 is filled with sponge. The sponge filling not only enhances the sealing performance between the discharge pipe 2 and the storage tank 3, but also effectively reduces the loss of heat energy. The sealing plate 5 is installed at the opening on the front of the collection box 101 by mounting bolts 4. A sealing gasket is provided at the connection between the sealing plate 5 and the collection box 101 to enhance its sealing performance and prevent heat loss from the connection. After the sealing plate 5 is removed from the collection box 101, it can be cleaned with a soft brush to ensure that there is no residual dust on the surface of the particle filter plate 106. During the cleaning process, care should be taken to avoid scratching or other damage to the plate to ensure that its filtration performance is not affected.

[0022] Please see Figures 1-2A hot gas inlet pipe 6 is fixedly connected to the bottom of the surface of storage tank 3 through a through hole. A discharge pipe 7 is fixedly connected to the middle of the upper end of storage tank 3 through a through hole. A blower 8 is fixedly connected to one end of the discharge pipe 7. The output end of the blower 8 is fixedly connected to the other end of the discharge pipe 2.

[0023] The portion of the discharge pipe 7 inside the storage tank 3 is wrapped with glass fiber cotton. Glass fiber cotton has excellent heat insulation performance and high temperature resistance, and can maintain a stable heat insulation effect for a long time.

[0024] Please see Figure 3 A double-pipe 9 is fixedly connected to one side of the collection box 101 through a through hole. A blower 10 is fixedly connected to the other end of the double-pipe 9. A discharge pipe 11 is fixedly connected to the output end of the blower 10. A heat insulation plate 12 is fixedly connected to the surface of the discharge pipe 11. A storage tank 13 is fixedly connected to the surface of the heat insulation plate 12. A hot gas outlet pipe 14 is fixedly connected to the bottom of the surface of the storage tank 13 through a through hole.

[0025] The heat insulation plate 12 divides the internal space of the storage tank 13 into upper and lower enclosed spaces. The heat insulation plate 12 is made of ceramic fiber cotton, which can effectively block hot air. The heat insulation plate 12 successfully isolates the hot air in the upper part of the storage tank 13, creating a working environment close to room temperature for the blower 10. This not only significantly extends the service life of the blower 10 and reduces the failure rate, but also ensures the stability of the working environment of the blower 10. Moreover, the heat insulation plate 12 made of ceramic fiber cotton not only has excellent high temperature resistance, but also greatly reduces heat transfer.

[0026] Please see Figures 1-2 The top of the surface of storage tank 13 is fixedly connected to one side of the surface of double pipe 9 through a through hole, and a reinforcing plate 15 is fixedly connected to the middle of the surface of double pipe 9.

[0027] The induced draft fan 8 and the forced draft fan 10 will generate continuous vibration during operation. The airflow itself will also cause the double-pipe 9 to vibrate. The reinforcing plate 15 is fixedly installed on the double-pipe 9, which enhances the structural stability of the double-pipe 9. This allows it to withstand a certain amount of external pressure and vibration during long-term use, while maintaining good sealing performance at the connection between the double-pipe 9 and the forced draft fan 10, thus avoiding loosening or leakage caused by vibration.

[0028] Please see Figures 1-2 The lower end of storage tank 13 is fixedly connected to a support base 16. The upper sides of the support base 16 are fixedly connected to a back reinforcement bracket 17 on the side near the back. One end of the back reinforcement bracket 17 is fixedly connected to the middle of the surface of storage tank 13 and storage tank 23 respectively.

[0029] The back reinforcement bracket 17 serves as a connection structure between storage tank 1 (3), storage tank 2 (13), and support base 16. The back reinforcement bracket 17 not only improves the stability of the overall structure but also effectively disperses the stress generated by storage tank 1 (3) and storage tank 2 (13) during operation, avoiding deformation or loosening of connections due to long-term use. At the same time, it further enhances the load-bearing capacity of support base 16, ensuring that the entire device can maintain a highly efficient and stable operating state under complex working conditions.

[0030] Please see Figures 1-2 A bottom support rod 18 is fixedly connected to the upper end of the support base 16 near the middle, and the upper end of the bottom support rod 18 is fixedly connected to the lower end of the collection box 101.

[0031] The bottom support rod 18 supports the bottom of the collection box 101, which not only effectively reduces the risk of sagging caused by gravity during use, but also further improves the stability of the overall structure. By tightly connecting the bottom support rod 18 to the support base 16, the positional stability of the collection box 101 under various working conditions is ensured, and displacement problems caused by external vibration or impact are avoided.

[0032] The working principle of this utility model is as follows: First, the hot air inlet pipe 6 is connected to the hot air outlet pipe of the stenter, and the hot air is initially discharged into the storage tank 3 for storage. Then, the hot air is extracted by the blower 8 and enters the collection box 101 through the outlet pipe 2. Adjusting the lever 104 causes the baffle plate 103 to slide horizontally within the rectangular groove 102. As the lever 104 slides, it pulls the adjusting block 105, causing the particulate filter plate 106 to rotate around the support shaft 107, changing the rotation angle of the particulate filter plate 106 and thus filtering out impurities from the hot air. Two particulate filter plates 106 can enhance the filtration effect. The filtered hot air is introduced into the storage tank 13 by the blower 10 through the double pipe 9. Finally, the hot air in the storage tank 13 is heat-conducted through its metal inner wall to achieve heat exchange. The preheated air is then sent into the setting machine through the hot air outlet pipe 14, thereby achieving efficient recovery and utilization of waste heat.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
