Description

Technical Field

[0001] This application relates to the field of stenters, and more particularly to a stenter with a waste heat recovery device. Background Technology

[0002] The setting machine is a core piece of equipment in textile finishing. It uses high-temperature hot air to stretch and set the shape of dyed and finished fabrics, ensuring dimensional stability and satisfactory hand feel. During the operation of the setting machine, the high-temperature exhaust gas carries a large amount of residual heat. Direct emission of this gas would not only waste energy but also pollute the environment.

[0003] Currently, the industry commonly installs waste heat recovery devices at the exhaust end of stenters. These devices absorb heat from the exhaust gas through heat exchangers, which is then used to preheat fresh air or heat chilled water, achieving energy conservation and consumption reduction. To prevent impurities in the exhaust gas from adhering to the heat exchanger surface, existing waste heat recovery devices typically include filter plates inside the recovery tank for pre-treatment and filtration of the exhaust gas.

[0004] Regarding the aforementioned technologies, with prolonged use, impurities tend to accumulate on the surface of the filter plate, clogging the mesh and increasing the resistance to waste gas flow, thereby reducing the efficiency of waste heat recovery. Utility Model Content

[0005] In order to reduce impurities on the surface of the filter plate and improve the efficiency of waste heat recovery, this application provides a stenter with a waste heat recovery device.

[0006] The stenter with a waste heat recovery device provided in this application adopts the following technical solution: A setting machine with a waste heat recovery device includes a setting machine body and a recovery box. One end of the recovery box is connected to the setting machine body. A heat exchange tube is connected inside the recovery box. A filter plate is provided on the side of the heat exchange tube near the setting machine body. A scraper is provided on the side of the filter plate near the setting machine body. The scraper is used to contact the filter plate. A rotating assembly is connected to the recovery box. The rotating assembly is used to drive the scraper to rotate and drive the scraper to push away impurities.

[0007] By adopting the above technical solution, during use, the exhaust gas discharged from the stenter body is first filtered by the filter plate to reduce impurities in the exhaust gas. When the exhaust gas passes through the filter plate, the rotating component drives the scraper to rotate along the surface of the filter plate. The scraper pushes the impurities accumulated on the filter plate off, minimizing the blockage of the filter plate mesh by impurities. This facilitates the smooth passage of exhaust gas through the filter plate, improves waste heat recovery efficiency, and reduces the adhesion of impurities to the surface of the heat exchange tube, thereby improving heat exchange efficiency and reducing energy waste.

[0008] Optionally, the rotating assembly includes a first motor, a first gear, and a second gear. One end of the scraper is connected to a support rod, the first gear is connected to the support rod, the first motor is connected to the recycling bin, the output shaft of the first motor is connected to a rotating rod, and the second gear is connected to the rotating rod. The first gear and the second gear mesh.

[0009] By adopting the above technical solution, when in use, the first motor drives the rotating rod and the first gear to rotate, and the first gear drives the second gear and the support rod to rotate through meshing transmission, thereby driving the scraper to rotate synchronously, so as to facilitate the scraper to push impurities away from the filter plate.

[0010] Optionally, a connection port for the filter plate to pass through is provided on one side of the recycling bin. The filter plate slides and fits into the inner wall of the connection port, and the filter plate is detachably connected to the recycling bin by bolts.

[0011] By adopting the above technical solution, when it is necessary to clean or replace the filter plate, the filter plate can be slid out along the inner wall of the connection port by unscrewing the bolts. After cleaning, the filter plate can be slid back into its original position and the bolts tightened to fix it. This simplifies the filter plate disassembly process, shortens maintenance time, and improves maintenance convenience.

[0012] Optionally, the first motor is connected to the recycling bin via a movable plate, the support rod is rotatably connected to the movable plate, and the movable plate slides in conjunction with the recycling bin.

[0013] By adopting the above technical solution, before disassembling the filter plate, the moving plate is pushed to move the first motor, support rod and scraper away from the filter plate, so as to avoid the scraper blocking the filter plate from being pulled out. After the filter plate is installed, the moving plate is pushed again to make the scraper return to its original position and fit against the filter plate, so as to provide sufficient operating space for the disassembly of the filter plate and avoid the scraper interfering with the maintenance operation.

[0014] Optionally, the movable plate is connected to a spring, one end of which is connected to the movable plate and the other end of which is connected to the inner wall of the recycling bin. The spring is used to drive the movable plate to move and drive the scraper to press against the filter plate.

[0015] By adopting the above technical solution, during use, the spring drives the moving plate to move and drives the scraper to press against the surface of the filter plate, thereby improving the cleaning effect of the scraper on the filter plate.

[0016] Optionally, the movable plate is connected to a push block, the recycling bin has a movable hole, the push block slides and fits into the inner wall of the movable hole, a limiting block is slidably sleeved on the push block, the recycling bin has a limiting groove, the limiting groove is connected to one end of the movable hole, and the limiting block is inserted into the recycling bin through the limiting groove.

[0017] By adopting the above technical solution, when disassembling the filter plate, pushing the push block and moving the moving plate away from the filter plate, and moving the limit block so that the limit block is inserted into the limit groove, the position of the moving plate can be locked, thus avoiding the spring from driving the moving plate and scraper to reset during the disassembly of the filter plate, interfering with the filter plate pulling operation, and improving the convenience of operation.

[0018] Optionally, the limiting block is connected to a first magnetic block, and the inner wall of the limiting groove is connected to a second magnetic block. When the limiting block approaches the inner wall of the limiting groove, the first magnetic block and the second magnetic block attract each other.

[0019] By adopting the above technical solution, after the limiting block is inserted into the limiting groove, the first magnetic block and the second magnetic block attract each other, which enhances the connection stability between the limiting block and the limiting groove and minimizes the possibility of the limiting block coming out of the limiting groove due to equipment vibration or accidental contact, thereby facilitating the disassembly of the filter plate.

[0020] Optionally, a collection box is connected to the bottom of the recycling bin. The collection box is located below the filter plate on the side near the body of the setting machine. A cleaning port is opened at one end of the collection box. An opening and closing plate is detachably connected to the collection box. The opening and closing plate is used to open or close the cleaning port.

[0021] By adopting the above technical solution, when in use, the scraper pushes the falling impurities into the collection box below, which facilitates the collection of impurities. When there are a lot of impurities in the collection box, the opening and closing plate can be opened to clean the impurities through the cleaning port, which facilitates the cleaning of impurities in the collection box.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the exhaust gas discharged from the stenter body is first filtered through the filter plate to reduce impurities in the exhaust gas. When the exhaust gas passes through the filter plate, the rotating component drives the scraper to rotate along the surface of the filter plate. The scraper pushes the impurities accumulated on the filter plate off, minimizing the blockage of the filter plate mesh by impurities. This facilitates the smooth passage of exhaust gas through the filter plate, improves waste heat recovery efficiency, and reduces the adhesion of impurities to the surface of the heat exchange tube, thereby improving heat exchange efficiency and reducing energy waste. 2. When the filter plate needs to be cleaned or replaced, simply unscrew the bolts to slide the filter plate out along the inner wall of the connection port. After cleaning, slide the filter plate back into its original position and tighten the bolts to fix it. This simplifies the filter plate disassembly process, shortens maintenance time, and improves maintenance convenience. 3. When using, before disassembling the filter plate, push the moving plate to move the first motor, support rod and scraper away from the filter plate, so as to avoid the scraper blocking the filter plate from being pulled out; after the filter plate is installed, push the moving plate again to make the scraper return to its original position and fit against the filter plate, so as to provide sufficient operating space for the filter plate disassembly and avoid the scraper interfering with the maintenance operation.
