[0002] The main reason for using non-woven fabrics for dust removal and sterilization is to ensure their safety and hygiene. During production and use, non-woven fabrics may come into contact with various microorganisms and bacteria, which, if not eliminated promptly, may pose a threat to human health.

[0003] Chinese patent announcement number CN220724645U discloses a dust removal and sterilization device for non-woven fabric processing. This device delivers disinfectant to various sets of atomizing nozzles, which then atomize and spray the disinfectant onto the non-woven fabric for sterilization. While this device can sterilize non-woven fabric, the amount of disinfectant sprayed is inconsistent. Insufficient spraying makes it difficult to penetrate the fabric, while excessive spraying can lead to over-spraying or even dripping onto the equipment, making it difficult to control the amount of disinfectant sprayed. To address these shortcomings, we propose a dust removal and sterilization device for non-woven fabric processing. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a dust removal and sterilization device for non-woven fabric processing, comprising: a sterilization structure and a drying structure.

[0029] The disinfection structure includes a disinfectant tank 10, a guide frame 11 fixedly installed on the right side of the disinfectant tank 10, a non-woven fabric guide assembly set inside the disinfectant tank 10, and a squeezing assembly set inside the guide frame 11. An overflow groove 50 is opened on the back of the disinfectant tank 10. An overflow frame 51 is fixedly installed on the inner wall of the overflow groove 50. An overflow pipe 52 is fixedly installed at the lower end of the overflow frame 51. An inlet pipe 53 is fixedly installed on the left side of the disinfectant tank 10. The inlet pipe 53 can be equipped with a solenoid valve and a liquid level sensor to realize automatic liquid replenishment (not shown in the figure). It is connected to an external recovery container through the overflow pipe 52 to form a dynamic liquid level balance and prevent disinfectant from overflowing.

[0030] The nonwoven fabric guiding assembly includes a first guide roller 30, a second guide roller 31, a third guide roller 32, and a fourth guide roller 33, which are rotatably connected to the inner wall of the disinfectant tank 10, and a fifth guide roller 34, which is rotatably connected to the inner wall of the guide frame 11. Disinfectant can be injected into the disinfectant tank 10 through the water inlet pipe 53 until the disinfectant submerges the second guide roller 31 and the third guide roller 32. Thus, the nonwoven fabric can be soaked in the disinfectant and disinfected by using the second guide roller 31 and the third guide roller 32.

[0031] The extrusion assembly includes a first extrusion roller 40 and a second extrusion roller 41 rotatably connected to the inner wall of the guide frame 11. The front surfaces of the first extrusion roller 40 and the second extrusion roller 41 extend to the front surface of the guide frame 11, and a first spur gear 42 and a second spur gear 43 are fixedly mounted thereon. A motor 44 is fixedly mounted on the front surface of the guide frame 11 to drive the first spur gear 42 to rotate. The first extrusion roller 40 and the second extrusion roller 41 are disposed between the fourth guide roller 33 and the fifth guide roller 34. A gap is provided between the first extrusion roller 40 and the second extrusion roller 41 for the nonwoven fabric to pass through. The first spur gear 42 and the second spur gear 43 mesh and drive each other.

[0032] The nonwoven fabric is passed through the gap between the first extrusion roller 40 and the second extrusion roller 41. When the drive motor 44 is activated, the first spur gear 42 and the second spur gear 43 mesh to drive the first extrusion roller 40 and the second extrusion roller 41 to squeeze the wetted nonwoven fabric. This squeezes out a large amount of disinfectant from the nonwoven fabric. The squeezed disinfectant flows back into the disinfectant tank 10 along the guide frame 11. By replacing the traditional atomized spraying, the disinfectant is ensured to fully penetrate the interior of the nonwoven fabric. At the same time, the first extrusion roller 40 and the second extrusion roller 41 forcibly remove excess liquid, solving the problem of "too little liquid makes it difficult to penetrate, too much liquid makes it easy to drip" in the existing atomized spraying technology.

[0033] The drying structure is located on the right side of the disinfectant tank 10. It includes a first drying box 20, a second drying box 21 located on the right side of the first drying box 20, multiple support rollers 22 rotatably connected to the inner walls of the first drying box 20 and the second drying box 21, a heat source fan 23 located on the back of the second drying box 21, a waste heat recovery component located between the first drying box 20 and the second drying box 21, and a first exhaust fan 24 located at the top of the first drying box 20. Both sides of the first drying box 20 and the second drying box 21 are provided with through slots for non-woven fabric to pass through. Driving the heat source fan 23 can deliver high-temperature air into the second drying box 21.

[0034] The waste heat recovery assembly includes a second exhaust fan 60 fixedly installed on the upper surface of the second drying chamber 21, and an exhaust pipe 61 fixedly installed at the exhaust end of the second exhaust fan 60. The other end of the exhaust pipe 61 is connected to the interior of the first drying chamber 20. The exhaust end of the heat source fan 23 and the intake end of the second exhaust fan 60 both extend into the interior of the second drying chamber 21, and the intake end of the first exhaust fan 24 extends into the interior of the first drying chamber 20.

[0035] The non-woven fabric, after being squeezed to remove disinfectant, passes through the first drying chamber 20 and the second drying chamber 21 respectively. Then, the non-woven fabric in the second drying chamber 21 is dried and disinfected at high temperature using a heat source fan 23. The second drying chamber 21 generates hot and humid air during drying. The hot and humid steam is drawn into the exhaust pipe 61 by the second exhaust fan 60. The exhaust pipe 61 then delivers the hot and humid air to the first drying chamber 20. When the hot and humid air enters the first drying chamber 20, it can preheat the non-woven fabric inside the first drying chamber 20. At the same time, the first exhaust fan 24 can exhaust the low-temperature hot air in the first drying chamber 20. By combining the first drying chamber 20 and the second drying chamber 21 with a waste heat recovery component, the hot and humid air discharged from the second drying chamber 21 can be delivered to the first drying chamber 20 through the exhaust pipe 61 and preheat the non-woven fabric, thereby reducing the energy consumption of the main drying section.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] Immersion disinfection stage: The non-woven fabric passes through the first guide roller 30, the second guide roller 31, the third guide roller 32, the fourth guide roller 33 and the fifth guide roller 34 in sequence. At this time, the non-woven fabric is immersed below the liquid surface of the disinfectant tank 10. The disinfectant fully penetrates the fiber layer through immersion for 5-8 seconds.

[0038] Squeeze-out stage

[0039] The motor 44 drives the first spur gear 42 and the second spur gear 43 to mesh and transmit power, which drives the first extrusion roller 40 and the second extrusion roller 41 to rotate in opposite directions and extrude non-woven fabric. The extruded liquid flows back to the disinfectant tank 10 through the guide frame 11 for recycling.

[0040] Drying stage

[0041] Pre-drying: The non-woven fabric is pulled to the right by the external winding structure. After squeezing out the disinfectant, the non-woven fabric enters the first drying box 20, where it absorbs the residual heat delivered by the exhaust pipe 61 and initially evaporates the surface moisture.

[0042] Main drying: The non-woven fabric enters the second drying chamber 21, where the heat source fan 23 sprays high-temperature airflow to penetrate the fabric surface and complete deep drying.

[0043] The exhaust fans work in tandem: the first exhaust fan 24 discharges low-temperature humid air, and the second exhaust fan 60 extracts the residual heat from the second drying box 20 and circulates it back to the first drying box 21 for use.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of this utility model should be included within the scope of protection of this utility model.
