Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figures 1 to 5 As shown, the device for preventing the escape of unorganized exhaust gas from the stenter is installed at the fabric outlet 11 of the stenter 1. Of course, the conveying mechanism 2 is installed through the stenter 1, and the conveying mechanism 2 outputs the fabric from the fabric outlet 11. This is known technology and will not be described in detail here.

[0019] This device includes two air curtain booster boxes 3 located outside the setting machine 1 and respectively above and below the fabric outlet 11. Each air curtain booster box 3 is provided with an air nozzle 31 that blows obliquely toward the fabric outlet 11. The air nozzle 31 of the upper air curtain booster box 3 blows obliquely toward the lower edge of the fabric outlet 11, and the air nozzle 31 of the lower air curtain booster box 3 blows obliquely toward the upper edge of the fabric outlet 11. The width of the air nozzle 31 is equal to the width of the fabric outlet 11. The air curtain booster box 3 is connected to a blower device 4.

[0020] The high-pressure airflow output by the blower 4 is evenly distributed by the air curtain booster box 3 and finally ejected from the nozzle 31. The ejected airflow forms an air curtain that blows obliquely towards the fabric outlet 11. The air curtains of the upper and lower air curtain booster boxes 3 converge inward at the fabric outlet 11. In addition, the nozzle 31 and the fabric outlet 11 are of the same width, and each air curtain blows at the upper and lower edges of the fabric outlet 11. Therefore, the fabric outlet 11 forms an inward air curtain airflow with good isolation, eliminating the escape of exhaust gas, reducing exhaust gas pollution, improving environmental protection, and also reducing the impact of high temperature and condensate.

[0021] In this embodiment, the air curtain pressurizing box 3 includes an air box wall 32 near the setting machine 1. A top wall 33 is fixedly provided on the end of the air box wall 32 away from the fabric outlet 11, extending along the direction away from the setting machine 1. A guide slope 34, smoothly extending towards the fabric outlet 11, is fixedly provided on the end of the top wall 33 away from the setting machine 1. An air box end wall 35 is fixedly provided at the ends of the air box wall 32, the top wall 33, and the guide slope 34, forming a box structure. An air nozzle 31 is formed between the end of the guide slope 34 near the fabric outlet 11 and the end of the air box wall 32 near the fabric outlet 11. With this structural configuration, the high-pressure airflow input into the air curtain pressurizing box 3 can be quickly guided by the guide slope 34 to form a uniform airflow ejected from the air nozzle 31, which facilitates the formation of an insulating air curtain.

[0022] The blower device 4 includes a blower 41, and each of the air curtain pressurization boxes 3 is connected to a blower pipe 42. The blower pipe 42 extends into the shaping machine 1 and the inner end of the blower pipe 42 is connected to the guide pipe 51 inside the shaping machine 1. The internal circulation fan 5 inside the shaping machine 1 also serves as the blower 41.

[0023] Therefore, in this embodiment, the original guide pipe 51 inside the setting machine 1 is directly connected to the blower pipe 42. The hot air blown out by the original internal circulation fan 5 inside the setting machine 1 is directly guided to the air curtain pressurization box 3, and then blown back towards the fabric outlet 11 through the air nozzle 31. This solution does not require an additional fan. In actual installation, the last one or several hot air pipes inside the setting machine 1 can be replaced with the blower pipe 42, which facilitates direct modification of the existing setting machine 1. Based on the above structural arrangement, most of the blower pipe 42 is inside the setting machine 1, resulting in less heat loss. The hot air from the last one or several hot air pipes is essentially redirected to the air curtain pressurization box 3 for reverse blowing, forming the required hot air drying at the fabric outlet 11. The drying and setting effect is not affected, and there is no increase in energy consumption. Furthermore, while reducing the emission of exhaust gas, it also helps to reduce heat loss, achieving energy-saving effects.

[0024] More specifically, the blower duct 42 includes two air-turning sections 43 disposed within the setting machine 1, one higher and one lower than the fabric outlet 11, respectively. The air-turning sections 43 are connected to the guide duct 51 and arranged in conjunction with the hot air duct within the setting machine 1. The ends of the two air-turning sections 43 furthest from the guide duct 51 are respectively connected to air supply sections 44 extending through the side wall of the setting machine 1. The two air supply sections 44 are respectively connected to the two air curtain booster boxes 3. In this embodiment, the air supply section 44 can be as follows: Figure 2The air box wall 32 shown is connected to the air box 3 of the air curtain pressurization box 3, and can also be as follows: Figure 5 The connection shown is to the end wall 35 of the air box 3, which is connected to the air box 3 of the air curtain pressurization box. No limitation is made here.

[0025] Based on the above structural principles, in this embodiment, the upper and lower air curtain pressurization boxes 3 together form a converging air curtain that blows air into the inside of the fabric outlet 11. Exhaust gas no longer escapes from the fabric outlet 11, which helps reduce exhaust pollution and improves environmental friendliness. Utilizing the original internal circulation fan 5 to provide a high-pressure air source eliminates the need for additional fans. The internal hot air achieves self-circulation, minimizing heat loss and reducing high-temperature dissipation, resulting in good energy efficiency.

[0026] Of course, the configuration of the blower device 4 described in this embodiment is not limited to the above structure. For example, when a heat exchanger for utilizing the heat of the waste gas is installed at the waste gas collection system of the stenter 1, the blower 41 in the blower device 4 can also use the hot air formed after absorbing the heat of the waste gas for blowing. This solution should also be within the protection scope of this utility model.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
