Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton processing technology, specifically to a dust collection device for cotton processing. Background Technology
[0002] Cotton processing refers to the process of removing impurities and separating usable fibers from harvested raw cotton through a series of physical treatments, ultimately producing clean cotton fibers for textile and other industrial production. Cotton dust removal refers to the removal of impurities and pollutants from cotton to ensure its quality and purity. When cotton enters a dust removal system, fine impurities such as dust and sand are removed through airflow and vibration. Cotton processing plants use baghouse dust collectors with external filtration for gas purification. After dust-laden air enters the dust collector, large dust particles settle naturally, while the remaining dust enters the filtration zone with the airflow and is adsorbed on the outer surface of the filter bags. The filter bags are cleaned by compressed air jet cleaning. With the continuous development of cotton processing, various dust collection devices for cotton processing have emerged, such as one type of dust collection device for cotton processing.
[0003] A search revealed a dust collection device for cotton processing in Chinese utility model patent CN202022118067.9. The device includes a support platform, a protective box, springs, a drive motor, a sieve cylinder, a vibrating motor, a vacuum cleaner, and a dust collection plate. The protective box is mounted on the support platform, and its bottom is fixed to the platform by several springs. A drive motor is fixed to one end of the protective box, and a connecting shaft is welded to the drive motor's rotating rod. The connecting shaft extends into the interior of the protective box, and a sieve cylinder is welded to its inner end. Vibrating motors are fixed to both sides of the protective box. A vacuum cleaner is fixed to one support leg of the support platform, and a dust collection plate is fixed to the inner bottom of the protective box, with the vacuum cleaner communicating with the dust collection plate. This cotton processing dust collection device utilizes a drive motor to rotate the screen cylinder, causing the cotton to continuously tumble, which facilitates thorough dust collection from all directions, thereby improving the dust removal effect. It features a simple overall structure, significant cleaning effect, and fast speed, greatly improving the purity of the cotton. However, while this equipment can continuously tumble the cotton for thorough dust collection, after prolonged use, dust remains inside the protective box and cannot all fall off. During subsequent use, the dust will fall into the cotton, hindering dust removal. Therefore, a new type of cotton processing dust collection device is proposed that can simultaneously tumble the cotton for dust removal and perform self-cleaning inside the working equipment, reducing dust residue and achieving more thorough dust removal. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a dust collection device for cotton processing. It has the advantages of being able to flip and remove dust while simultaneously self-cleaning the inside of the working equipment, which helps reduce dust residue and achieves cleaner dust removal. This solves the problem in Chinese Utility Model Patent No. CN202022118067.9 that after long-term use, dust rises and remains attached to the inside of the protective box and cannot be completely removed, causing dust to fall into the cotton during the next use.
[0005] To achieve the above-mentioned purpose of being able to flip and remove dust while simultaneously self-cleaning the inside of the working equipment, thereby reducing dust residue and making dust removal more thorough, this utility model provides the following technical solution: a dust collection device for cotton processing, including a working box, the top of which is hinged with a cover plate, and a dust removal mechanism is provided on the outside of the working box;
[0006] The dust removal mechanism includes a servo motor, a rotating rod, a filter frame, an exhaust pipe, an exhaust fan, a high-pressure centrifugal fan, dust collection plates, an electric telescopic rod, and an electric vibrator. A servo motor is fixedly installed externally on the working box, and a rotating rod is located at the output end of the servo motor. A filter frame is fixedly connected externally to the rotating rod. An exhaust pipe is provided inside the working box, and an exhaust fan and a high-pressure centrifugal fan are fixedly installed inside the working box. Two dust collection plates and two electric telescopic rods are fixedly installed inside the working box.
[0007] Furthermore, a filter screen plate is hinged to the outside of the filter screen frame, and a buckle adapted to the filter screen plate is provided on the outside of the filter screen frame. By providing the filter screen plate, the filter screen plate can be opened to put cotton in, and by providing the buckle, the filter screen plate can be closed and fixed by the buckle after the cotton is put in.
[0008] Furthermore, a suction hose is fixedly connected to the right side of the exhaust fan, and the left side of the exhaust fan is connected to the exhaust pipe. By setting up the suction hose, it is beneficial to discharge the dusty air inside the working box through the exhaust pipe into the suction hose.
[0009] Furthermore, four spring shock absorbers are fixedly installed at the bottom of the work box. The four spring shock absorbers are evenly distributed at the bottom of the work box. By setting four spring shock absorbers, it is beneficial to shake off dust after the electric vibrator is turned on, and to buffer the vibration through the spring shock absorbers.
[0010] Furthermore, scrapers are fixedly connected to the bottom of both of the electric telescopic rods, and a rubber layer is provided on the outside of both scrapers. By setting the scrapers and the rubber layer, the dust adsorbed on the dust collection plate can be scraped off.
[0011] Furthermore, the working chamber is equipped with two high-voltage electrodes, which can ionize the air.
[0012] Furthermore, a PLC controller is fixedly installed on the front of the work box. The PLC controller is electrically connected to the servo motor, exhaust fan, high-pressure centrifugal fan, dust collection plate, electric telescopic rod, electric vibrator and high-voltage electrode through wires.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] This dust collection device for cotton processing, through its dust removal mechanism, allows for the opening of the cover plate and filter screen when dust removal is needed. The cotton is placed inside the filter screen frame and then closed. The PLC controller then activates the servo motor, exhaust fan, and electric vibrator, causing the cotton in the filter screen frame to tumble and dust to escape. A portion of the dust is removed by the exhaust fan, and the PLC controller activates a high-pressure centrifugal fan to blow up any remaining dust. The air is ionized by a high-voltage electrode, giving the dust particles a negative charge. Upon contact with the dust collection plate, the dust particles adhere firmly due to the mirror force generated by the induced charge. The high-pressure centrifugal fan is then turned off, and the electric telescopic rod is activated to scrape the dust off into the exhaust pipe. This dust removal mechanism not only removes dust by tumbling but also self-cleans the interior of the equipment, reducing dust residue and achieving more thorough dust removal.

[0024] In the implementation of the case, scrapers 7 are fixedly connected to the bottom of the two electric telescopic rods 308. The outer surface of the two scrapers 7 is provided with a rubber layer. By setting the scrapers 7 and the rubber layer, the dust adsorbed on the dust collection plate 307 can be scraped off.
[0025] In the case implementation, the work box 1 is equipped with two high-voltage electrodes 8. By setting the high-voltage electrodes 8, the air can be ionized. The support of the high-voltage electrodes 8 is made of polytetrafluoroethylene, and the high-voltage leads are protected by double-layer silicone, which is beneficial to the insulation design. The high-voltage electrodes 8 can be opened to cut off the power and grounded to discharge.
[0026] In the implementation of this case, the key parameters of this patent are as follows:
[0027] part Materials / Process Key features High voltage electrode Tungsten wire (Φ0.3mm) Resistant to ion bombardment, lifespan ≥5000h Dust collection plate Anodized aluminum (film thickness 20μm) Surface resistance 10 < sup scraper PTFE + glass fiber Coefficient of friction <0.1, hardness D55
[0028] In the implementation of the case, a PLC controller 9 is fixedly installed on the front of the work box 1. The PLC controller 9 is electrically connected to all electronic components in this patent through wires, so that all electronic components in this patent can be controlled by operating the PLC controller 9. The PLC controller 9 is equipped with an intelligent chip, which can achieve the effect of timed start-up.
[0029] When implementing this procedure, please follow these steps:
[0030] 1) When it is necessary to remove dust from the cotton, open the cover plate 2 and the filter plate 4, put the cotton into the filter frame 303 and close it. Then, turn on the servo motor 301, the exhaust fan 305 and the electric vibrator 309 through the PLC controller 9.

[0032] 3) The air is then ionized by the high-voltage electrode 8, and the dust particles are negatively charged. When the dust particles come into contact with the dust collection plate 307, they are firmly attached due to the mirror force generated by the induced charge.
[0033] 4) Finally, turn off the high-pressure centrifugal fan 306 and turn on the electric telescopic rod 308 to scrape the dust down into the exhaust pipe 304.
[0034] In summary, this dust collection device for cotton processing, by setting up a dust removal mechanism 3, allows the cotton to be placed inside the filter frame 303 when dust removal is needed.

A portion of the dust is removed by the exhaust fan 305, and the high-pressure centrifugal fan 306 is activated via the PLC controller 9 to blow up any remaining dust. The air is ionized by the high-voltage electrode 8, and the dust particles become negatively charged. Upon contact with the dust collection plate 307, the dust particles adhere firmly due to the mirror force generated by the induced charge. The high-pressure centrifugal fan 306 is then turned off, and the electric telescopic rod 308 is activated to scrape the dust off and into the exhaust pipe 304. This dust removal mechanism 3 can both tumble and remove dust while simultaneously self-cleaning the inside of the working equipment, which helps reduce dust residue and achieves cleaner dust removal.
