Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing technology, and in particular to an adjustable heat dissipation chimney structure for use in tenter frame. Background Technology

[0002] During the early stages of spinning, weaving, and dyeing, the fibers of a fabric generate internal stress, which can cause the fabric to shrink and deform. However, the heating of a tenter frame can rearrange and shape the fiber molecular chains, thereby significantly reducing the shrinkage rate during subsequent use, ensuring the stability of the finished product dimensions, making the fabric surface smoother, and reducing wrinkles. For example, Chinese Patent No. CN210104298U discloses a tenter frame. In the use of such a device, the exhaust gas generated by the setting oven is drawn by an exhaust fan and then filtered through a filter assembly, so that the exhaust gas can be discharged after filtration, reducing environmental pollution.

[0003] However, the tenter frames described in the aforementioned patents and those currently used in the market still have some shortcomings: when the tenter frame heats the textile fabric, it often requires a sufficiently long initial period to maintain a stable temperature within the frame. Since the exhaust from the tenter frame is usually fixed, during this period, the exhaust not only carries away a significant amount of heat, prolonging the time required to stabilize the heat, but also leads to unstable heat flow and poor uniform heating of the textile fabric. Therefore, those skilled in the art have provided an adjustable heat dissipation chimney structure for the tenter frame to solve the problems mentioned in the background section.

[0014] This utility model provides an adjustable heat dissipation chimney structure for use in a tenter frame, which has the following advantages compared with the prior art:

[0015] 1. The adjustable heat dissipation chimney structure for the tenter frame can dynamically adjust the exhaust gas discharge rate by using the adjustable opening and closing of the valve plate assembly when discharging exhaust gas inside the tenter frame.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This utility model provides a technical solution for an adjustable heat dissipation chimney structure for a tenter frame: An adjustable heat dissipation chimney structure for a tenter frame includes an air inlet pipe 1, which has multiple sets connected to the heat chamber of the tenter frame. Simultaneously, an exhaust pipe 2 is provided at the exhaust port of each set of air inlet pipes 1. The exhaust pipe 2 has a valve plate assembly 9 along its flue gas flow direction. A filter assembly 8 is provided on one side of the valve plate assembly 9, and a flow guide valve plate 6 is provided on one side of the filter assembly 8. Through the setting of the valve plate assembly 9, the exhaust gas discharge rate inside the tenter frame can be dynamically adjusted, allowing the valve plate assembly 9 to gradually open and close according to the temperature rise inside the tenter frame, achieving uniform heat rise and avoiding a rapid exhaust gas emission rate in the initial stage of heat rise. Excessive heating can lead to an imbalance in heat generation, resulting in slow and unstable heating. This design ensures uniform heating of the textile fabric. Furthermore, the dynamic opening and closing of the valve plate assembly 9 acts as a limiting guide plate, maintaining the same conduction area in the filter assembly 8. This ensures that the filtration and purification area remains appropriately sized according to the volume of exhaust gas, resulting in more stable exhaust gas flow. Simultaneously, the dynamic opening and closing of the valve plate assembly 9 controls the synchronous dynamic opening and closing of the guide valve plate 6, further stabilizing and orderly exhaust gas flow. Moreover, the dynamic opening and closing of the valve plate assembly 9 also simultaneously cleans the filter assembly 8, allowing impurities adhering to the filter assembly 8 to be self-removed, improving the smoothness of exhaust gas emission.

[0028] It should be noted that the exhaust port of the exhaust pipe 2 is provided with a manifold pipe 3, and the exhaust port of the manifold pipe 3 is provided with a vent pipe 4. By using the manifold pipe 3 as a collection pipe for the heat exhaust gas of the tenter frame, the exhaust gas is filtered and purified and then discharged through the vent pipe 4.

[0029] As a further embodiment, the valve plate assembly 9 includes a first drive shaft 91, which has a hollow structure, and a second drive shaft 92 is rotatably mounted inside the cavity. Both the first drive shaft 91 and the second drive shaft 92 are fixedly connected to an opening / closing valve plate 96. The two sets of opening / closing valve plates 96 are arranged opposite to each other, and a scraper 97 is provided at the top of each valve plate 96. Simultaneously, a first bevel gear 93 is provided at one end of the first drive shaft 91, and a second bevel gear 94 is provided at one end of the second drive shaft 92. The second drive shaft 92 and the second bevel gear 94 are connected by a third bevel gear 95 for transmission. This allows for the control of exhaust... The pipeline 2 is equipped with a motor 5 that drives the first drive shaft 91. The motor 5 is used as the drive source to drive the first drive shaft 91 to rotate. When the first drive shaft 91 rotates, it drives the first bevel gear 93 to rotate. Through the meshing transmission of the third bevel gear 95, it drives the second bevel gear 94 to rotate in the opposite direction, which in turn drives the second drive shaft 92 to rotate in the opposite direction relative to the first drive shaft 91. Through the relative rotation of the first drive shaft 91 and the second drive shaft 92, the two sets of opening and closing valve plates 96 are driven to swing in opposite directions, controlling the dynamic conversion of the exhaust port size of the exhaust pipeline 2, so that the exhaust gas in the tenter frame maintains a dynamic emission rate.

[0030] It should be noted that the first drive shaft 91 has an axial clearance cavity 98, which provides the space required for the second drive shaft 92 to be fixedly connected to the valve plate 96. By setting the clearance cavity 98, the second drive shaft 92 can be coaxial with the first drive shaft 91, and can also be fixedly connected to the valve plate 96, so that the two sets of valve plates 96 can oscillate around the same axis.

[0031] Furthermore, the filter assembly 8 includes a frame 84, inside which a filter plate component is provided, and the frame 84 has an elastic support component. The elastic support component includes a fixed seat 81, and a guide rod 83 is slidably installed inside the fixed seat 81. The guide rod 83 is fixedly connected to the frame 84, and a compression spring 82 that is elastically connected to the frame 84 is sleeved on the outside of the guide rod 83. When the valve plate assembly 9 drives its opening and closing valve plate 96 to open and close, the opening and closing of the valve plate 96 can push the frame 84 to move along the exhaust gas direction through the scraper 97 at its top, so that the opening and closing valve plate 96 is always in contact with the frame 84, forming a limiting guide plate. This allows the opening and closing valve plate 96 to isolate the filter assembly 8 into a dynamically changing filtration and purification area. On the one hand, this improves the stability of exhaust gas flow, and on the other hand, when the scraper 97 pushes the frame 84 to move, it can also scrape and clean the impurities that are adhered to the filter plate component, thus ensuring the smooth filtration and purification characteristics of the filter plate component.

[0032] It should be noted that the filter plate component includes a dust removal mesh plate 85, a first adsorption mesh plate 86, and a second adsorption mesh plate 87 arranged along the flue gas flow direction. The dust removal mesh plate 85 can be made of stainless steel mesh to filter impurities and other components in the exhaust gas. The first adsorption mesh plate 86 and the second adsorption mesh plate 87 can be made of activated carbon mesh, sponge mesh, etc., to adsorb and purify odors and other harmful gases in the exhaust gas.

[0033] In addition to the above, there are two sets of flow guide valve plates 6. The two sets of flow guide valve plates 6 are rotatably installed on the exhaust pipe 2 through the pivot pin 610. Each set of flow guide valve plates 6 has a connecting rod 7 connected to the filter assembly 8 on one side. When the filter assembly 8 moves, its moving force is converted into thrust, which is transmitted to the flow guide valve plate 6 through the connecting rod 7. This makes the two sets of flow guide valve plates 6 keep in a synchronous opening and closing state with the opening and closing of the valve plate assembly 9. On the one hand, it plays a guiding role, making the flow of exhaust gas more uniform and stable. On the other hand, it can reduce the situation of exhaust gas flowing back into the exhaust pipe 2 from the manifold 3.

[0034] The working principle of this utility model is as follows: During the exhaust process of the exhaust gas inside the tenter frame, the intake fan 10 is used to adsorb and treat the exhaust gas. When the exhaust gas flows from the intake pipe 1 to the exhaust pipe 2, the valve plate assembly 9 can be dynamically opened and closed to dynamically adjust the exhaust rate of the exhaust gas inside the tenter frame. This allows the valve plate assembly 9 to gradually open and close according to the temperature rise inside the tenter frame. For example, when the temperature inside the tenter frame is initially rising, the valve plate assembly 9 is opened to a smaller extent, making the temperature rise inside the tenter frame more stable and uniform. This ensures uniform temperature rise and avoids the situation where the exhaust gas emission rate is too fast in the initial stage of temperature rise, leading to an imbalance in temperature rise, slow heating efficiency, and unstable temperature rise.

[0035] While the valve plate assembly 9 is dynamically opening and closing, the opening and closing of the valve plate can also act as a limiting guide plate, so that the filter screen assembly 8 maintains the same size of conduction area, so as to maintain a suitable size of filtration and purification area in sync with the size of exhaust gas emission, making the flow of exhaust gas more stable, and smoothly purifying the exhaust gas through the exhaust pipe 2. At the same time, the dynamic opening and closing of the valve plate assembly 9 can also act on the scraping and cleaning of the filter screen assembly 8, so that the impurities adhering to the filter screen assembly 8 are self-removed, improving the smoothness of exhaust gas emission.

[0036] Furthermore, the dynamic opening and closing of the valve plate assembly 9 can control the synchronous dynamic opening and closing of the guide valve plate 6, further making the flow of exhaust gas more stable and orderly, and discharging the exhaust gas through the manifold 3 into the venting pipe 4 for stable discharge.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
