Description

Technical Field

[0001] This invention belongs to the field of cotton cleaning, specifically a dust cage filtration and dust removal device for a cotton cleaning machine. Background Technology

[0002] Cotton cleaning is a crucial step in the cotton processing production process, directly determining the cleanliness, quality grade, and market value of the finished cotton product. As a core processing piece of equipment, the cotton cleaning machine is primarily used to remove foreign matter such as cotton fibers, dust, broken leaves, and impurities from cotton lint, effectively improving the quality of cotton processing. During equipment operation, a large amount of fine dust and light impurities are generated. If dust removal cannot be completed in a timely and efficient manner, these impurities and dust will continue to mix with the cotton material, not only reducing the cleaning effect and affecting the quality of the finished product, but also causing dust accumulation and blockage inside the equipment, accelerating equipment wear, and polluting the workshop production environment, posing certain production safety hazards. Currently, most cotton cleaning machines on the market are equipped with a dust cage filtration structure. Its working principle is mainly to collect the dust-laden airflow generated by the equipment operation through the dust cage, and then use an internal filter to intercept and filter the dust-laden airflow, trapping and separating the dust and light impurities in the airflow, completing the air-dust separation and dust removal operation, and ensuring the normal progress of the cotton cleaning process. This type of filter dust removal structure is simple in structure and low in cost, and can meet basic dust removal needs. Therefore, it is widely used in various small and medium-sized cotton processing equipment. However, it has the following drawbacks: During the continuous flow and filtration of dust-laden airflow, fine dust and short fibers easily adhere to and accumulate inside and on the surface of the filter mesh, unable to be discharged in time with the airflow. Over time, this accumulation gradually blocks the filter mesh. As the degree of mesh blockage worsens, the ventilation and permeability of the filter mesh decreases significantly, and the airflow efficiency inside the dust cage is significantly reduced. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a dust cage filtration and dust removal device for a cotton cleaning machine, which effectively solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dust cage filtration and dust removal device for a cotton cleaning machine, comprising a cylindrical dust cage, wherein a dust discharge shaft pipe is provided at the end of the cylindrical dust cage, and one end of the dust discharge shaft pipe is connected to a dust cleaning component; The dust cleaning assembly includes a cleaning cylinder, an inner fixed cylinder inside the cleaning cylinder, an air inlet pipe connected to one side of the inner fixed cylinder, a rotating connector between the air inlet pipe and the dust discharge pipe of the cylindrical dust cage, and a dust handling component above the inner fixed cylinder. The dust handling component includes an internal rotating cylinder positioned above an internal fixed cylinder. A rotation drive component is connected and installed at the top of the internal rotating cylinder. Multiple dust blocking modules are arranged longitudinally and equidistantly inside the internal rotating cylinder. The dust blocking modules are arranged in a labyrinthine pattern to block dust. At the same time, a dust discharge control component is provided on the outside of the cleaning cylinder. The internal rotating cylinder rotates relative to the dust discharge control component to achieve rotational friction, which aggravates the surface of the dust blocking modules with static electricity, thereby improving the dust collection effect. The dust discharge control component is used to control the dust discharge.

[0005] Preferably, the internal rotating cylinder includes a metal cylinder disposed above the internal fixed cylinder. An insulating layer is disposed on the outer wall of the metal cylinder. PTFE friction rings are disposed at equal intervals on the longitudinal outer surface of the insulating layer. Each PTFE friction ring corresponds to a dust blocking module. The metal cylinder is made of conductive metal, and the insulating layer is made of PTFE.

[0006] Preferably, the dust blocking module includes a lower conical disc and an upper conical disc, both of which are conical structures. A longitudinal pipe is fixedly installed between the lower and upper conical discs, with the bottom end of the longitudinal pipe extending to the bottom of the lower conical disc. A first flow groove is circumferentially opened at the top end of the longitudinal pipe. Multiple annular plates are fixedly installed on the bottom wall of the upper conical disc, with the diameter of the multiple annular plates increasing sequentially. A second flow groove is opened on the outer circumferential side of the upper conical disc. Multiple ash discharge chute is opened on the side wall of the inner rotating cylinder, with each ash discharge chute corresponding to one of the lower conical discs, and the ash discharge chute is inclined along the upper surface of the lower conical disc.

[0007] Preferably, the PTFE friction ring is located above the ash discharge chute, and the materials of the upper conical disc and the annular plate are the same as those of the metal cylinder, all of which are made of conductive metal.

[0008] Preferably, a rotating tube is coaxially rotatably connected to the top of the internal rotating cylinder, and an air suction pump is installed on the dust cleaning assembly. A flexible hose is installed between one end of the air suction pump and the rotating tube.

[0009] Preferably, the rotation drive component includes a gear ring coaxially fixedly mounted on the top of the inner rotating cylinder, a gear meshing on one side of the gear ring, the gear being fixedly connected to the output shaft of the drive motor, and the drive motor being mounted on the cleaning cylinder.

[0010] Preferably, the top of the cleaning cylinder is provided with a top groove, and the top of the inner rotating cylinder is located inside the top groove. A first insulating and sealed bearing is installed between the bottom wall of the inner rotating cylinder and the top wall of the inner fixed cylinder, and a second insulating and sealed bearing is installed between the top outer wall of the inner rotating cylinder and the inner side wall of the top groove.

[0011] Preferably, the ash discharge control component includes baffle modules equidistantly arranged on the outer side of the inner rotating cylinder; The baffle module includes a cylindrical ring sleeved and installed on the outside of the inner rotating cylinder. The inner wall of the cylindrical ring is in close contact with the outer wall of the inner rotating cylinder, and the top of the cylindrical ring has an inclined part. A nylon ring is installed on the inner side of the cylindrical ring. When the nylon ring contacts the PTFE friction ring, the cylindrical ring closes the ash discharge chute.

[0012] Preferably, a cylinder is fixedly installed at the top of the cleaning cylinder, and a vertical rod is fixedly installed at the output end of the cylinder. The vertical rod is inserted longitudinally into the interior of the cleaning cylinder and is fixedly connected to each cylinder ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, the dust blocking module consists of two conical upper and lower cones arranged in parallel. When dust containing air flows, it impacts the bottom wall of the inclined upper cone from the first flow groove at the top of the longitudinal tube, which facilitates the blocking and separation of dust. After the dust falls, it can be discharged downward along the top wall of the inclined lower cone, which facilitates the dust discharge and collection. (2) In this invention, multiple dust blocking modules are equidistantly arranged from bottom to top inside the internal rotating cylinder. Air containing dust continuously enters the space between the lower cone disk and the upper cone disk. Multiple annular plates are installed on the bottom wall of the upper cone disk, and a maze is formed between the lower cone disk and the upper cone disk, which improves the dust blocking and separation effect, avoids airflow blockage, and improves dust treatment efficiency. (3) In this invention, when the ash discharge chute is closed by the cylindrical ring, the nylon ring and the PTFE friction ring come into contact, and when the internal rotating cylinder rotates, the two rub against each other to generate static electricity. The static electricity is transferred to the upper conical plate and the annular plate, which further improves the dust blocking and separation effect when the air is circulating. (4) In this invention, after the cylinder ring moves upward, the nylon ring and the PTFE friction ring are separated, so that static electricity is no longer generated, and the ash discharge chute is opened. Under the action of the centrifugal force of the internal rotating cylinder, the dust that is statically adsorbed to the surface of the upper cone plate and the ring plate is thrown off and discharged from the ash discharge chute into the cleaning cylinder, which facilitates the discharge and collection of dust.

[0017] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figure 1 The present invention relates to a dust cage filtration and dust removal device for a cotton cleaning machine, comprising a cylindrical dust cage 1, wherein a dust discharge shaft tube is provided at one end of the cylindrical dust cage 1, and one end of the dust discharge shaft tube is connected to a dust cleaning component 3.

[0019] Depend on Figure 2 The dust cleaning assembly 3 includes a cleaning cylinder 31, an inner fixed cylinder 33 is provided inside the cleaning cylinder 31, an air inlet pipe 34 is connected and installed on one side of the inner fixed cylinder 33, a rotating connector is provided between the air inlet pipe 34 and the dust discharge pipe of the cylindrical dust cage 1, and a dust handling component 36 is provided above the inner fixed cylinder 33. Depend on Figures 3-5 The dust handling component 36 includes an internal rotating cylinder 361 positioned above an internal fixed cylinder 33. A rotation drive component is connected to the top of the internal rotating cylinder 361. Multiple dust blocking modules 364 are arranged longitudinally and equidistantly inside the internal rotating cylinder 361. The dust blocking modules 364 are arranged in a labyrinthine configuration to block dust. Meanwhile, a dust discharge control component 37 is provided on the outside of the cleaning cylinder 31. The internal rotating cylinder 361 rotates relative to the dust discharge control component 37 to achieve rotational friction, which aggravates the surface of the dust blocking modules 364 with static electricity, thereby improving the dust collection effect. At the same time, the dust discharge control component 37 is used to control the dust discharge. A rotating tube 362 is coaxially rotatably connected to the top of the internal rotating cylinder 361. An air suction pump 2 is installed on the dust cleaning component 361. A flexible hose is connected between one end of the air suction pump 2 and the rotating tube 362.

[0020] The internal rotating cylinder 361 includes a metal cylinder 3611 disposed above the internal fixed cylinder 33. An insulating layer 3612 is disposed on the outer wall of the metal cylinder 3611. PTFE friction rings 3613 are equidistantly disposed on the longitudinal outer surface of the insulating layer 3612. The PTFE friction rings 3613 correspond one-to-one with the dust blocking module 364. The metal cylinder 3611 is made of conductive metal, and the insulating layer 3612 is made of PTFE.

[0021] The dust blocking module 364 includes a lower conical disk 3641 and an upper conical disk 3642. Both the lower conical disk 3641 and the upper conical disk 3642 are conical structures. A longitudinal tube 3643 is fixedly installed between the lower conical disk 3641 and the upper conical disk 3642. The dust blocking module 364 consists of two conical upper conical disks 3642 and lower conical disk 3641 arranged parallel to each other. When dust containing air flows, it is flushed from the first circumferential flow groove 3644 at the top of the longitudinal tube 3643. The dust impacts the bottom wall of the downward-sloping upper conical disk 3642, facilitating dust interception and separation. After falling, the dust can be discharged downwards along the top wall of the downward-sloping lower conical disk 3641, facilitating dust discharge and collection. The bottom end of the longitudinal pipe 3643 extends below the lower conical disk 3641, and a first flow groove 3644 is circumferentially formed at the top of the longitudinal pipe 3643. Multiple annular plates 3645 are fixedly installed on the bottom wall of the upper conical disk 3642, with the diameters of the annular plates 3645 sequentially increasing. The upper conical disc 3642 is enlarged, and a second flow groove 3646 is opened outward from the circumference. Multiple ash discharge chute 3647s are opened on the side wall of the inner rotating cylinder 361. Each ash discharge chute 3647 corresponds to one of the lower conical discs 3641, and the ash discharge chute 3647s are inclined along the upper surface of the lower conical disc 3641. A PTFE friction ring 3613 is located above the ash discharge chute 3647s. The materials of the upper conical disc 3642 and the annular plate 3645 are the same as those of the metal cylinder 3611. The materials are the same, all made of conductive metal. Multiple dust blocking modules 364 are equidistantly arranged from bottom to top inside the internal rotating cylinder 361. Dust-laden air continuously enters the space between the lower cone disk 3641 and the upper cone disk 3642. Multiple annular plates 3645 are installed on the bottom wall of the upper cone disk 3642. A maze is formed between the lower cone disk 3641 and the upper cone disk 3642, which improves the dust blocking and separation effect, avoids airflow blockage, and improves dust handling efficiency.

[0022] The rotation drive component includes a gear ring 363 coaxially fixedly mounted on the top end of the inner rotating cylinder 361. A gear 310 is meshed on one side of the gear ring 363. The gear 310 is fixedly connected to the output shaft of the drive motor 311. The drive motor 311 is mounted on the cleaning cylinder 31. A top groove 35 is opened at the top end of the cleaning cylinder 31. The top end of the inner rotating cylinder 361 is located inside the top groove 35. A first insulating and sealed bearing 38 is installed between the bottom wall of the inner rotating cylinder 361 and the top wall of the inner fixed cylinder 33. A second insulating and sealed bearing 39 is installed between the top outer wall of the inner rotating cylinder 361 and the inner side wall of the top groove 35.

[0023] Depend on Figures 6-7 As shown, the ash discharge control component 37 includes baffle modules 373 that are equidistantly arranged on the outside of the inner rotating cylinder 361; The baffle module 373 includes a cylindrical ring 3731 sleeved and installed on the outside of the inner rotating cylinder 361. The inner wall of the cylindrical ring 3731 is in close contact with the outer wall of the inner rotating cylinder 361, and the top of the cylindrical ring 3731 has an inclined portion 3732. A nylon ring 3733 is installed on the inner side of the cylindrical ring 3731. When the cylindrical ring 3731 closes the ash discharge chute 3647, the nylon ring 3733 contacts the PTFE friction ring 3613, and the two rub against each other to generate static electricity when the inner rotating cylinder 361 rotates. The static electricity is transferred to the upper conical disk 3642 and the annular plate 3645, so that the air circulation... At the same time, to further improve the dust blocking and separation effect, when the nylon ring 3733 contacts the PTFE friction ring 3613, the cylindrical ring 3731 closes the ash discharge chute 3647. After the cylindrical ring 3731 moves upward, the nylon ring 3733 separates from the PTFE friction ring 3613, so that static electricity is no longer generated, and the ash discharge chute 3647 is opened. Under the action of the centrifugal force of the internal rotating cylinder 361, the dust that is electrostatically adsorbed to the surface of the upper cone plate 3642 and the annular plate 3645 is thrown off and discharged from the ash discharge chute 3647 into the cleaning cylinder 31, which facilitates the discharge and collection of dust. A cylinder 372 is fixedly installed at the top of the cleaning cylinder 31. A vertical rod 371 is fixedly installed at the output end of the cylinder 372. The vertical rod 371 is inserted longitudinally into the interior of the cleaning cylinder 31 and is fixedly connected to each cylinder ring 3731.

[0024] A conductive ring is fitted around the outer side of the inner rotating cylinder 361. The conductive ring is in contact with the metal cylinder 3611 and is electrically connected to a grounding wire. A conductive switch is installed on the grounding wire. In the original state, the conductive ring is fitted around the outer side of the inner rotating cylinder 361, and is in contact with the metal cylinder 3611. The conductive ring is electrically connected to a grounding wire and a conductive switch is installed on the grounding wire. The conductive switch is in the de-energized state to allow dust to be attracted after static electricity is generated. However, when the baffle module 373 moves upward, the conductive switch is turned on to allow the static electricity to be discharged quickly, facilitating the dust to fall.

[0025] Working principle: When in use, the suction pump 2 is turned on, so that negative pressure is applied to the inside of the cylindrical dust cage 1, which draws outside air into the inside of the cylindrical dust cage 1 and flows through the inside of the dust cleaning component 3. The cylindrical dust cage 1 rotates continuously above the cotton lint. Under the action of negative pressure, the dust in the cotton lint is sucked into the inside of the cylindrical dust cage 1. At the same time, the drive motor 311 is turned on, which drives the gear 310 to rotate. The gear 310 meshes with the toothed ring 363 at the top of the internal rotating cylinder 361, thereby driving the internal rotating cylinder 361 to rotate continuously. Then, under negative pressure, dusty air continuously enters the inner fixed cylinder 33 from the air inlet pipe 34, and then flows upward continuously, passing through the dust blocking module 364 inside the inner rotating cylinder 361. During the flow of a single dust blocking module 364, the dusty air enters the longitudinal pipe 3643 upward, and enters the space between the lower cone plate 3641 and the upper cone plate 3642 from the first flow groove 3644 on the circumferential side of the top of the longitudinal pipe 3643. Then, it flows along the downward sloping bottom wall of the upper cone plate 3642 and passes through multiple annular plates 3645. Finally, it flows upward from the second flow groove 3646 on the outer side of the upper cone plate 3642, realizing labyrinthine flow and improving the dust blocking effect in the air. Meanwhile, during the rotation of the internal rotating cylinder 361, the nylon ring 3733 and the PTFE friction ring 3613 come into contact. During the rotation, the nylon ring 3733 and the PTFE friction ring 3613 rub against each other and generate static electricity. The static electricity is then conducted to the surface of the upper conical disk 3642 and multiple annular plates 3645. When dusty air flows through, the dust is attracted by static electricity, which improves the dust separation effect. Finally, the air is discharged from the rotating tube 362 at the top of the internal rotating cylinder 361 and the tail end of the suction pump 2. When dust collection is required, cylinder 372 pulls vertical rod 371 upward, which in turn pulls each baffle module 373 upward, causing nylon ring 3733 to separate from PTFE friction ring 3613, thus preventing further static electricity generation. At the same time, the dust discharge chute 3647 is opened, and the dust falls onto the inclined top wall of the lower cone plate 3641 under the centrifugal force of the internal rotating cylinder 361. Then, it is discharged directly from the dust discharge chute 3647 into the cleaning cylinder 31, and finally discharged from the dust discharge pipe 32. In the original state, a conductive ring is installed on the outside of the internal rotating cylinder 361, which is in contact with the metal cylinder 3611. The conductive ring is electrically connected to a grounding wire, and a conductive switch is installed on the grounding wire. The conductive switch is in the de-energized state to keep the dust adsorbed after static electricity is generated. When the baffle module 373 moves upward, the conductive switch is turned on to allow the static electricity to be discharged quickly, facilitating the dust to fall.
