[0016] In summary, this application has the following beneficial effects: 1.

[0017] 2. Improve separation purity; the charge of the particles is enhanced through the corona discharge zone, so that cotton particles and dust particles are more easily attracted to the corresponding electrode plates, thereby improving separation purity.

[0018] 3. Vibration cleaning: The magnetic piston compresses the gas in the guide rail to generate intermittent vibration to assist scraping and cleaning equipment. Vibration cleaning can loosen and remove particles accumulated on the corona discharge device, keep the corona discharge device clean and ensure its normal operation.

[0022] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method: Figure 1-14 Shown.

[0024] A cotton wool recovery device suitable for refined cotton crushing equipment comprises a plurality of symmetrically arranged corona electrode plates 1, the outer ends of the plurality of corona electrode plates 1 are fixedly connected with a plurality of uniformly distributed needle-shaped electrodes 2, the bottom ends of the corona electrode plates 1 are fixedly connected with a deflector 3, the bottom ends of the deflector 3 are fixedly connected with a separation basket 4, the outer ends of the separation basket 4 are fixedly connected with a plurality of rectangular grooves 5, and the plurality of rectangular grooves 5 are symmetrically arranged about the center plane of the separation basket 4, the inner walls of the separation basket 4 are fixedly connected with a first pole plate pair 6, a second pole plate pair 7, a third pole plate pair 8 and a fourth pole plate pair 9, the inner ends of the plurality of rectangular grooves 5 are all slidably connected with a first magnetic pole 10, the outer walls of the plurality of rectangular grooves 5 are slidably connected with a plurality of second magnetic poles 11 corresponding to the positions of the first magnetic poles 10, the inner ends of the plurality of first magnetic poles 10 are fixedly connected with a scraper shaft 12, the outer ends of the scraper shaft 12 are fixedly connected with a scraper 13, and the inner ends of the second magnetic poles 11 are rotatably connected with a drive shaft 14.

[0025] The corona electrode plate 1 includes a plurality of symmetrically arranged corona electrode plates 1, the outer ends of which are fixedly connected with a plurality of uniformly distributed needle-shaped electrodes 2, the needle-shaped electrodes 2 can enhance the effect of corona discharge, make the electric field distribution more uniform, thereby improving the charging efficiency of cotton wool particles and dust particles, the needle-shaped electrodes 2 can generate a strong electric field, promote the ionization of gas molecules, and enhance the charging effect of particles, the flow guide 3 helps to guide the gas flow, so that the gas enters the separation basket 4 more uniformly, and improves the separation efficiency, the separation basket 4, the separation basket 4 provides space for accommodating the pole plates, and the symmetrically arranged rectangular grooves 5 help to evenly distribute the electric field and improve the separation effect, the rectangular grooves 5 are symmetrically arranged about the center plane of the separation basket 4, the rectangular grooves 5 help to fix the first magnetic pole 10 and the second magnetic pole 11, and provide conditions for non-contact transmission; The inner wall of the separation basket 4 is fixedly connected with the first pole plate pair 6, the second pole plate pair 7, the third pole plate pair 8 and the fourth pole plate pair 9 to form a stable electric field to promote the separation of particles. The first magnetic pole 10 and the second magnetic pole 11 form a strong magnetic non-contact connection, which helps to drive the scraper shaft 12 to move. The scraper shaft 12 drives the scraper 13 to move to scrape the particles on the electrode plate. The scraper 13 can effectively scrape the particles on the electrode plate to keep the electrode plate clean and improve the separation efficiency. The drive shaft 14 realizes intermittent rotation through the internal spring 15 and steel ball 16, so that the scraper 13 does not contact the electrode plate when it goes up, and contacts the electrode plate when it goes down, which helps the scraper 13 to contact the electrode plate to achieve scraping.

[0026] The second implementation method: Figure 1-14 Shown.

[0027] The end of the spring 15 close to the steel ball 16 abuts against the steel ball 16, and the end of the spring 15 away from the steel ball 16 abuts against the bottom of the countersink. The spring 15 provides elastic force, so that the steel ball 16 can move in the countersink to achieve the locking and unlocking functions. The inner wall of the second magnetic pole 11 is provided with a plurality of hemispherical grooves, and the inner walls of the hemispherical grooves are all contacted with steel balls 16. The diameter of the steel ball 16 is the same as the diameter of the countersink. The cooperation of the steel ball 16 and the countersink realizes the locking and unlocking functions of the scraper 13. When the steel ball 16 is pressed into the countersink, the spring 15 can move in the countersink to achieve the locking and unlocking functions of the scraper 13. The spring 15 contracts, and when the steel ball 16 bounces back into the hemispherical groove, locking is achieved, and the scraper 13 is in contact with and separated from the electrode plate. When the roller of the first adjusting rod 17 contacts the upper wedge block 22, the second magnetic pole 11 is rotated downward by 30 degrees, so that the scraper 13 contacts the electrode plate. The design of the roller reduces friction, making the adjustment smoother. When the second adjusting rod 18 contacts the lower wedge block 21, the scraper 13 returns to its original position. The angle of 60° ensures the coordination of the actions of the two adjusting rods at different positions. The top of the bottom plate 19 is fixedly connected with a lower wedge block 21, which contacts the roller of the second adjusting rod 18, so that the scraper 13 is reset when it moves to the bottom, avoiding the scraper 13 from contacting the electrode plate when it goes up, reducing the wear on the surface of the electrode plate. The bottom end of the cover plate 20 is fixedly connected with an upper wedge block 22, which contacts the roller of the first adjusting rod 17, so that the second magnetic pole 11 rotates downward by 30 degrees, thereby driving the scraper 13 to contact the electrode plate for scraping. The design of the wedge block makes the action more stable and reliable. The outer end of the driving shaft 14 is fixedly connected with a transverse plate 23. The transverse plate 23 serves as a supporting structure and is connected with a plurality of self-driven electromagnetic sliders 24 to ensure the stability and parallelism of the scraper 13 when it moves. The plurality of self-driven electromagnetic sliders 24 are distributed in a linear array along the axis of the transverse plate 23. The self-driven electromagnetic sliders 24 are driven by electromagnetics to move up and down, driving the scraper 13 to perform scraping and resetting operations. The linear array distribution ensures that the plurality of scrapers 13 work synchronously, thereby improving the scraping efficiency. The guide rail 25 ensures that the self-driven electromagnetic sliders 24 move smoothly along the predetermined track, thereby reducing friction and wear and improving the movement accuracy of the scraper 13. The inner wall of the guide rail 25 is slidably connected with a magnetic piston 26 corresponding to the position of the self-driven electromagnetic slider 24. When the self-driven electromagnetic slider 24 moves, the magnetic piston 26 compresses the gas in the guide rail 25 to generate compressed gas, which acts on the gas vibrator 27 through a pipeline to generate intermittent vibration to assist the scraping and cleaning equipment. The outer end of the guide rail 25 is fixedly connected with the gas vibrator 27 through a pipeline, and the guide rail 25 is connected to the gas vibrator 27. The bottom end of the gas vibrator 27 is fixedly connected to the outer wall of the guide cover 3. The gas vibrator 27 generates intermittent vibration through compressed gas to assist the scraping and cleaning equipment, reduce the residue of particulate matter on the electrode plate, improve the thoroughness of scraping, keep the electrode plate clean, and ensure the normal operation of the corona discharge device; The bottom end of the bottom plate 19 is fixedly connected with a collecting bin 28, which collects the separated particles. The partition 29 divides the collecting bin 28 into a dust collecting bin and a cotton wool bin, which is convenient for classifying and collecting different types of particles, improving the convenience and efficiency of subsequent processing. The exhaust pipe is used to discharge the cleaned gas to reduce secondary pollution. The cyclone separator 30 removes larger cotton wool particles through centrifugal force, reduces the total amount of particles entering the electrostatic separator, reduces the load of the electrostatic separator, and prolongs the service life of the equipment. The air inlet of the cyclone separator 30 is connected to the collection bin 28 to ensure that the separated particles are effectively collected; The electrode plates adjacent to the first electrode plate pair 6 and the second electrode plate pair 7 are negative electrode plates, the electrode plates adjacent to the second electrode plate pair 7 and the third electrode plate pair 8 are positive electrode plates, and the electrode plates adjacent to the third electrode plate pair 8 and the fourth electrode plate pair 9 are negative electrode plates. The same polarity of adjacent electrode plates can form a stable electric field, which helps cotton wool particles and dust particles move to the negative electrode plate and the positive electrode plate respectively, thereby achieving efficient separation while ensuring the purity of the separation. Polytetrafluoroethylene has good corrosion resistance and low friction coefficient, which can reduce the adhesion of particulate matter on the electrode plates and facilitate cleaning. The same gap between the electrode plates can ensure uniform distribution of the electric field and improve separation efficiency.

[0028] The third implementation method: Figure 1-14 Shown.

[0029] The steps include: S1, initial separation; When the refined cotton is crushed, the fan sends the dust and cotton wool particles generated in the crushing process into the tangential air inlet of the partition 29. After the gas enters, a spiral downward outer vortex is formed. During this process, due to the action of centrifugal force, the heavier cotton wool particles are pushed to the cylinder wall, and the cotton wool particles move downward along the cylinder wall to the bottom of the cone, and then are discharged into the gas vibrator 27 through the bottom pipe. The separated gas forms an ascending inner vortex in the center of the cyclone separator and flows out through the top pipe to the next process. Since the dust particles are relatively small and light, they will continue to move upward with the airflow and flow out through the top pipe. The cotton wool particles are larger and heavier, and are more easily affected by the centrifugal force, and thus are separated.

[0030] By removing larger cotton wool particles through a cyclone separator, the total amount of particles entering the electrostatic separation can be reduced, reducing the load on the electrostatic separator, allowing it to focus on processing smaller dust particles, improving the overall separation efficiency, and reducing the amount of large particles entering the electrostatic separator, which can reduce the wear of the electrode plates and other components and extend the service life of the equipment.

[0031] S2, charge injection; After the preliminary separation by the partition 29, the mixed gas enters the corona discharge zone between the two corona electrode plates 1 through the pipeline. The corona discharge generates a large number of free electrons and positive ions. Cotton wool particles are usually composed of natural cellulose fibers, have a high electron affinity, and are more likely to lose electrons. Cotton wool particles tend to be positively charged. On the contrary, the composition of dust particles is more complex, usually containing metal oxides, minerals, and other organic and inorganic substances, with lower electron affinity, and they are more likely to obtain electrons. During the discharge process of the needle-shaped electrode 2, the electric field generated by the electrode will cause the surrounding gas molecules to ionize and generate positive ions and negative ions. Cotton wool particles, due to their characteristic of easily losing electrons, will be positively charged under the action of the corona electric field. Dust particles, due to their characteristic of easily obtaining electrons, will be negatively charged under the same conditions.

[0032] Through the above method, the charge of cotton wool particles and dust particles can be effectively enhanced, thereby improving the efficiency of electrostatic separation. The cotton wool and dust particles with enhanced charge are subjected to greater force in the electric field, making the cotton wool particles and dust particles more easily attracted to the corresponding plates. At the same time, the stronger charge helps the particles to be captured faster, reducing the possibility of particles escaping without being collected.

[0033] S3, electric field separation; The mixed gas after charge injection enters the gap area between the first electrode plate pair 6, the second electrode plate pair 7, the third electrode plate pair 8 and the fourth electrode plate pair 9, and the control system energizes the positive and negative electrode plates. The electrode plates adjacent to the first electrode plate pair 6 and the second electrode plate pair 7 are negative electrodes, the electrode plates adjacent to the second electrode plate pair 7 and the third electrode plate pair 8 are positive electrodes, and the electrode plates adjacent to the third electrode plate pair 8 and the fourth electrode plate pair 9 are negative electrodes. When the mixed gas passes through the gap area between the electrodes, the cotton wool particles will be adsorbed on the negative electrode plate, and the dust will be adsorbed on the positive electrode plate, so that the dust and cotton wool particles are completely separated. When a certain thickness of particles accumulates on the electrode plate, the control system drives the scraping device to clean the cotton wool particles and dust particles.

[0034] Since cotton wool particles are positively charged and dust particles are negatively charged, they will move toward the negative plate and the positive plate respectively in the electric field, thus achieving efficient separation while ensuring the purity of the separation.

[0035] S4, scraping and collecting; When cotton wool particles and dust particles gather on the electrode plate, the control system drives the self-driven electromagnetic slider 24 to move upward along the guide rail 25, and the self-driven electromagnetic slider 24 drives the cross plate 23 to move, and the cross plate 23 drives multiple second magnetic poles 11 to move along the rectangular groove 5. Since the second magnetic pole 11 and the first magnetic pole 10 are strongly magnetically non-contact connected, when the second magnetic pole 11 moves, the first magnetic pole 10 also moves, thereby driving the scraper shaft 12 to move upward. When the self-driven electromagnetic slider 24 moves to the top, the first adjusting rod 17 at the outer end of the second magnetic pole 11 contacts the upper wedge block 22, causing the second magnetic pole 11 to rotate downward 30 degrees in the cyclone separator. During rotation, the steel ball 16 inside the second magnetic pole 11 is pressed into the counterweight on the drive shaft 14. The hole makes the spring 15 contract. After the cyclone separator is rotated 30 degrees, the steel ball 16 is bounced back into the hemispherical groove on the second magnetic pole 11 under the elastic force of the spring 15 to achieve locking. At the same time, the second magnetic pole 11 drives the first magnetic pole 10 to rotate, so that the scraper 13 contacts the surface of the electrode plate. After the rotation is completed, the control system controls the self-driven electromagnetic slider 24 to move downward, and the scraper 13 scrapes away the particles gathered on the surface of the electrode plate and drops them into the collecting bin 28 to complete the collection. When the scraper 13 moves to the bottom, the second adjusting rod 18 contacts the lower wedge block 21 to make the scraper 13 return to its original position. In this way, reciprocating motion is used to complete the scraping. When moving upward, the scraper 13 is prevented from contacting the electrode plate to prevent the interest-free particles and dust particles from mixing again.

[0036] When the scraper 13 is moving upward, it does not contact the electrode plate, which can reduce the wear on the surface of the electrode plate and affect the function and life of the electrode plate. When the scraper 13 is moving downward, it can effectively scrape off the particles adsorbed on the electrode plate and keep the electrode plate clean. The clean electrode plate can ensure the stability of the electric field, thereby maintaining an efficient separation effect. Adding a rotation function can prevent the scraper 13 from shoveling off the adsorbed particles when moving upward, causing re-mixing of the particles.

[0037] S5, vibration cleaning; During the scraping process, the self-driven electromagnetic slider 24 can drive the magnetic piston 26 in the guide rail 25 to move at the same time. When the magnetic piston 26 moves to the bottom of the guide rail 25, the magnetic piston 26 compresses the gas in the guide rail 25. The compressed gas acts on the gas vibrator 27 through the pipeline, causing the gas vibrator 27 to produce intermittent vibrations, assisting the scraping and cleaning equipment. The scraped and collected particles fall into the dust collecting bin under the action of the partition 29, and the interest-free particles fall into the cotton bin.

[0038] Vibration-assisted scraping can reduce the amount of particles remaining on the electrode plate and improve the thoroughness of scraping. Vibration can loosen and remove particles accumulated on the corona discharge device, keep the corona discharge device clean and ensure its normal operation. Regular cleaning can prevent the corona discharge device from being blocked due to accumulation of particles, thereby maintaining the efficiency of corona discharge.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.

10. The method for using the cotton wool recovery device suitable for refined cotton crushing equipment according to any one of claims 1 to 9, characterized in that: The steps include: S1. Preliminary separation When the refined cotton is crushed, the fan sends the generated dust and cotton wool particles into the tangential air inlet of the partition (29), and the larger particles are removed by the cyclone separator (30), thereby reducing the load of the electrostatic separator and extending the service life of the equipment; S2, charge injection; The mixed gas after preliminary separation enters the corona discharge area through the pipeline. The corona discharge makes the cotton wool particles positively charged and the dust particles negatively charged, which increases the charge of the particles and improves the electrostatic separation efficiency. S3, electric field separation; The charged mixed gas enters the gap area between multiple pairs of electrode plates, and the control system energizes the positive and negative electrode plates. The cotton wool particles are adsorbed on the negative electrode plate, and the dust particles are adsorbed on the positive electrode plate, achieving efficient separation and ensuring separation purity. S4, scraping and collecting; When particles gather on the electrode plate, the control system drives the self-driven electromagnetic slider (24) to drive the scraper (13) to move up and down. When moving up, the scraper does not contact the electrode plate to reduce the wear of the electrode plate. When moving down, the scraper contacts the electrode plate to scrape the particles. After scraping, the particles fall into the collection bin (28) to prevent the particles from being mixed again. S5, vibration cleaning; During the scraping process, the self-driven electromagnetic slider (24) drives the magnetic piston (26) to move, and the compressed gas acts on the gas vibrator (27) through the pipeline to generate intermittent vibration. The vibration assists the scraping and cleaning equipment, reduces the residual particles, and keeps the electrode plate and the corona discharge device clean.
