[0002] The energy-saving drying equipment of the double-sided spray-type textile stenter setting machine adopts double-sided spray technology to accurately and evenly atomize and spray the treatment liquid (such as softener and water-repellent) onto both sides of the fabric through nozzles. Compared with single-sided treatment, it is faster and more uniform, and significantly reduces the energy consumption load of subsequent drying. Its drying system usually integrates high-efficiency hot air circulation, intelligent temperature control zoning and waste heat recovery device to maximize the use of heat energy and avoid ineffective loss.

[0003] Patent application number 202310048925.2 discloses a high-efficiency and energy-saving stenter setting machine with waste heat recycling of exhaust gas and its use method, including an exhaust gas filter assembly, an exhaust gas filter assembly and an exhaust gas heat exchange assembly arranged on the periphery of the setting machine chassis. The high-efficiency and energy-saving stenter setting machine with waste heat recycling of exhaust gas and its use method, after the exhaust gas in the setting machine chassis is discharged through the exhaust pipe, the oil is filtered through the exhaust gas filter assembly, and then impurities are removed through the exhaust gas filter assembly, thereby effectively reducing the impurity content in the exhaust gas, making the setting machine chassis more energy-efficient when working.

[0004] However, the existing double-sided spray stenter setting machines have the following problems: First, the fixed nozzle design leads to uneven airflow distribution, which easily creates drying dead zones in the width direction of the fabric and causes high moisture content fluctuations, forcing the overall drying time to be extended, resulting in energy waste; second, the static dust filtration system has difficulty coping with high-flocculation exhaust gas, the filter clogging rate is high, the increased wind resistance causes increased dehumidification energy consumption, and the machine needs to be shut down for manual disassembly and cleaning, which shortens the service life of the filter.

[0005] In view of this, we propose an energy-saving drying equipment for a double-sided spray-type textile stenter setting machine. Summary of the Invention

The bottom surface of the outer tube wall of the suction hood is integrally formed with a slag discharge frame extending to the bottom of the outer cover. The scraper is fixed on the inner wall of the outer tube body of the suction hood, and an air hole connected to the bottom surface and the outer wall near the guide blade is opened inside the scraper.

The push rod pushes the slider and drives the convex shaft to move along the cam groove, driving the rotating shaft to rotate, and allowing the baffle to change the fixed angle in the slag discharge frame.

[0021] The above setting uses the power of the motor to automatically and regularly clean the dust in the slag discharge frame to prevent excessive dust accumulation.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. This energy-saving drying equipment of the double-sided spray-type textile stenter setting machine uses a motor to drive a reciprocating screw to move the movable frame back and forth. The mechanical coordination of the protruding rod and the inclined slot converts the linear motion into the left and right reciprocating motion of the slide. The frame teeth then engage the tube teeth to synchronously drive all the nozzles to swing left and right. The nozzles dynamically sweep to form a turbulent flow field that evenly covers the fabric, completely eliminating the airflow dead zone of the fixed nozzles, compressing the fluctuation range of the fabric moisture content, improving the heat and mass transfer efficiency of the fabric surface, shortening the drying time, and reducing rework energy consumption and material waste.

[0023] 2. This double-sided spray-type textile stenter setting machine is an energy-saving drying device. The exhaust fan absorbs exhaust gas into the rotating dust filter tube. The transmission rod drives the filter tube to rotate continuously through the engagement of the worm and worm gear. The scraper automatically peels off impurities from the filter screen during the rotation of the filter tube, maintaining a constant dehumidification wind resistance and avoiding the increase in energy consumption caused by the blockage of traditional filter screens. The push rod links the slider to make the baffle periodically flip in the slag discharge frame. The dust is diverted to the slag collection area through the dynamic baffle, achieving zero manual cleaning and extending the life of the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS
