Technical Field

[0001] This invention relates to the field of textile pollution control technology, specifically a negative pressure dust collection device for clean production in the spinning process. Background Technology

[0002] During the spinning process, especially in the carding, combing, and drawing processes, a large amount of short fibers, fly waste, and dust are generated. These pollutants not only seriously deteriorate the workshop working environment and endanger the health of employees, but also affect the quality of semi-finished products and finished yarns, leading to an increase in yarn defects and breakage rates.

[0003] In existing technologies, spinning equipment typically uses externally attached vacuum cleaners for dust removal, but these externally attached vacuum cleaners have significant limitations: 1. Its dust collection efficiency is limited by the distance between the suction port and the dust generation point, and it is not effective in capturing dispersed dust sources; 2. Secondly, the pipeline system is complex and has high energy consumption. After long-term operation, fibers tend to accumulate in the pipes and filters, which not only increases the frequency of maintenance but also poses the risk of blockage and fire. 3. In addition, the device has poor linkage with the main unit, which makes it unable to achieve precise dust removal and affects the overall operational stability. Summary of the Invention

[0004] The purpose of this invention is to provide a negative pressure dust collection device for clean production in the spinning process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A negative pressure dust collection device for clean production in a spinning process includes a base plate.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figure 1-7This embodiment provides a negative pressure dust collection device for clean production in a spinning process, including a base plate 1. Multiple vertically oriented first electric cylinders 3 are arranged above the base plate 1. A dust collection chamber 4 is arranged above the first electric cylinders 3. An inverted U-shaped treatment cover 5 is arranged on the side of the dust collection chamber 4. The first electric cylinders 3 can drive the dust collection chamber 4 and the treatment cover 5 to move up and down, facilitating their covering of the spinning process, especially the conveyor belt. At least two insert plates 6 are inserted and removable on the side of the treatment cover 5 adjacent to the dust collection chamber 4. Adhesive plates 18 are provided on the insert plates 6. The insert plates 6 can be flexibly adjusted as needed. Adhesive plates 18 are attached to the insert plates 6 to collect dust. Dust is adsorbed. The insert plate 6 adopts a flexible and convenient plug-in design. Multiple binding rods 17 are provided on the inner periphery of the treatment hood 5. Adhesive plates 18 are plugged and pulled between the binding rods 17 and the treatment hood 5. A motor 23 is provided on the inner side of the treatment hood 5. A fan 19 is provided on the output end of the motor 23. The rear side of the fan 19 is connected to the dust collection chamber 4. A three-way valve 20 is provided on one side of the fan 19. An L-shaped suction pipe 21 is symmetrically provided on the end of the three-way valve 20 away from the fan 19. Multiple suction heads 22 are provided on the suction pipe 21. A bottom box 16 is provided above the bottom plate 1. The bottom box 16 can also hold some of the large dust particles or larger debris that fall.

[0019] First, the dust collection chamber 4 and the inverted U-shaped treatment hood 5 are moved up or down as a whole by the first electric cylinder 3, so that they cover the spinning equipment, such as the conveyor belt. Then, the motor 23 is started to drive the fan 19 to run, forming a stable negative pressure environment inside the closed treatment hood 5. The flying lint and dust generated during the spinning process are sucked into the system by the multiple sets of suction heads 22 on the suction pipe 21 under the action of negative pressure. The dust-laden airflow is regulated by the three-way valve 20 and finally enters the dust collection chamber 4 for centralized collection. During this process, the plug-in plate 6 and its surface adhesive plate 18 can be flexibly combined and installed to assist in the adsorption of suspended particles. The additional adhesive plate 18 on the restraining rod 17 on the inner wall of the treatment hood 5 further enhances the capture ability of fine dust, realizing multi-stage dust removal. The device's insert plate 6 and adhesive plate 18 design significantly improves maintenance convenience and adaptability. It can quickly adjust the filter unit according to the characteristics of the dust. The negative pressure closed dust collection structure effectively curbs dust diffusion from the source, significantly improving the air quality in the workshop. The combination of multi-stage adhesion and centralized collection takes into account both particulate matter capture efficiency and energy consumption control, meeting the requirements of clean production. The overall liftable design allows it to flexibly adapt to different process equipment, with high linkage, improving the device's versatility while reducing overall operation and maintenance costs.

[0020] A side base plate 2 is provided on one side of the base plate 1 via a docking assembly. A second electric cylinder 7 is symmetrically arranged above the side base plate 2. An air pump 8 is arranged above the second electric cylinder 7. A purging assembly 9 is arranged on the air pump 8. The purging assembly 9 includes a flange 901, an air outlet plate 902, and air outlet holes 903. A flange 901 is provided on the output end of the air pump 8. The air outlet plate 902 is arranged between the flanges 901. The air outlet plate 902 is inclined. The air outlet holes 903 are arranged in an array on the air outlet plate 902.

[0021] When the surface of the spinning equipment or dust collection device needs cleaning, the second electric cylinder 7 is activated, raising the air pump 8 and the blowing assembly 9 to a suitable height and angle. After the air pump 8 is activated, the high-speed airflow generated is delivered through the flange 901 to the inclined air outlet plate 902, and finally sprayed out evenly and concentratedly from the array of air outlet holes 903. This directional airflow can effectively blow away the flying lint and dust deposited on the surface of the equipment, such as the conveyor belt and the outer shell of the processing hood 5, making them suspend, thereby creating capture conditions for subsequent negative pressure dust collection, completing a cleaning cycle of blowing first and then collecting. The inclined air outlet plate 902, combined with the array of air outlet holes 903, can form a wide-coverage and uniformly forceful air curtain, achieving efficient and comprehensive blowing and cleaning, avoiding cleaning dead corners. The height can be flexibly adjusted by the second electric cylinder 7, allowing the component to accurately adapt to the needs of different equipment and cleaning locations. It has a high degree of automation, reducing the safety risks and labor intensity of manual cleaning. The blowing component 9 is connected by the flange 901, which enables convenient disassembly and maintenance, effectively improving the overall efficiency and automation level of the entire cleaning process.

[0022] The docking assembly includes docking posts 25 and threaded rods 26. The docking posts 25 are disposed on both sides of the base plate 1 and the side base plate 2, and the threaded rods 26 are inserted through the docking posts 25 to dock and fix the base plate 1 and the side base plate 2. When docking the base plate 1 and the side base plate 2, the holes of the docking posts 25 on the side base plate 2 are first precisely aligned with those of the docking posts 25 on the base plate 1. Then, the threaded rods 26 are sequentially inserted into the through holes of all the docking posts 25 to ensure that they pass through the entire docking point. Finally, nuts or other fasteners are used to tighten the threaded rods 26 at both ends. The axial locking force generated by the threads firmly presses the base plate 1 and the side base plate 2 together to form a stable rigid connection.

[0023] A water tank 10 is provided on the side of the first electric cylinder 3 away from the treatment hood 5. Water pumps 12 are provided on both sides of the base plate 1. The output end of the water pump 12 is connected to the water tank 10 through a water pipe 11. A water lower plate 13 is connected to one side of the water pump 12 through a water pipe 11. The bottom of the water lower plate 13 is laser-processed with multiple evenly distributed atomizing holes to facilitate dust collection on both sides of the treatment hood 5.

[0024] When environmental dust suppression is required, water pump 12 starts, pumping water from water tank 10 into water plate 13 through water pipe 11. After the water flow is evenly distributed in water plate 13, it is sprayed out from the dense atomizing holes laser-processed at the bottom, forming a fine and uniform water mist curtain. This water mist covers the outer space on both sides of the treatment hood 5, which can effectively capture and condense suspended dust particles in the air, causing them to settle after gaining weight, thereby achieving the purpose of auxiliary dust removal and air humidification and purification. This design greatly increases the contact area with dust, improves the efficiency of agglomeration and settling, and achieves efficient wet dust suppression. As a supplement to negative pressure dust collection, this system can handle the escaped fine dust and significantly improve the overall workshop environment.

[0025] The drain plate 13 is made of engineering plastic. A dust collection box 14 made of stainless steel is set below the drain plate 13. Shock-absorbing strips 24 are set on both sides of the second electric cylinder 7. A vertical front cover 15 is set above the side bottom plate 2. The front cover 15 and the treatment cover 5 are fitted together to complete the upper end sealing treatment. The upper end of the front cover 15 is square and the side adjacent to the treatment cover 5 is open. The lower part of the front cover 15 is a telescopic plate that can be flexibly adjusted up and down. The air inlet of the suction head 22 is shaped like a horn. A sealing strip with a semi-circular cross section is set at the joint between the front cover 15 and the treatment cover 5.

[0026] After the water mist sprayed from the water plate 13 completes the dust condensation and settling, the remaining dust-laden water droplets and sediment will drip downwards. At this time, the stainless steel dust collection box 14 will effectively receive and collect them. When the front cover 15 is height-adjusted by the telescopic plate below it and closes to the treatment hood 5, the square opening at the top of the front cover 15 is tightly connected to the treatment hood 5. The semi-circular sealing strip at the joint is deformed by pressure, forming a sealed space. This sealed space ensures the effective range of the airflow and negative pressure dust collection generated by the blowing assembly 9. At the same time, the funnel-shaped suction head 22 can effectively expand the air intake area, reduce wind resistance, and improve suction efficiency. The shock-absorbing strips 24 on both sides of the second electric cylinder 7 play a buffering role throughout the process, ensuring the smooth operation of the second electric cylinder 7. The front cover 15 and the treatment cover 5 achieve a flexible and reliable dynamic seal through the cooperation of the telescopic plate and the sealing strip, which effectively prevents the leakage of dust and airflow and improves the system's sealing performance. The flared design of the suction head 22 optimizes the airflow field. These details work together to significantly improve the collection efficiency, environmental adaptability and service life of the entire device. This device functions like an intelligent dust removal robot. When in operation, it first lowers or raises the treatment hood 5 like closing a lid, covering the area of ​​the spinning machine where dust is generated. Next, it activates the internal blowing assembly 9 to blow up the dust accumulated on the equipment surface. Then, it immediately starts a negative pressure dust collection system to suck up the suspended dust through the suction head 22. Some fine lint is also trapped by the dust-sticking plate inside the chamber. To combat dust that drifts outside the treatment hood 5 and the front cover 15, it is also equipped with a misting dust removal system, spraying water mist to make the dust heavier and fall down, where it is caught by the dust collection box 14 below. Throughout the process, the various components, through their height-adjustable and retractable design and tight-fitting sealing strips, form a relatively enclosed dust removal space, thereby achieving efficient and automated cleaning from the source of dust to the surrounding environment, contributing to the comprehensive treatment of environmental pollution. The insert plate 6 and the adhesive plate 18 form a modular filter unit that can be quickly replaced, greatly simplifying daily cleaning and maintenance. The blowing assembly 9 achieves precise positioning through the second electric cylinder 7, and together with negative pressure suction, it forms an efficient automated cleaning process of blowing first and then suction. The liftable treatment hood 5 and the front cover 15 with sealing strips together create a dynamic sealed space that can flexibly adapt to different equipment, preventing dust leakage from the source. The combination of the engineering plastic drain plate 13 and the stainless steel dust collection box 14 forms a durable water mist dust suppression and sewage collection system, which serves as an effective supplement to negative pressure dust collection. In addition, the horn design of the suction head 22 optimizes the suction efficiency, and the use of the shock-absorbing strip 24 ensures stable operation. These details are interconnected and together contribute to the comprehensive advantages of this device in terms of dust removal efficiency, ease of operation, environmental adaptability, and long-term operational reliability.
