Description

Technical Field

[0002] Dust collectors can be divided into two categories: handheld portable and fixed. They have different characteristics according to usage requirements and scenarios. Handheld portable dust collectors are small, light and easy to carry, suitable for cleaning small environments. Fixed dust collectors are usually larger and installed in specific locations. They are mainly used for dust removal in industrial sites or large areas.

The combined dust collector of the above scheme has the advantages of high dust removal efficiency and good dust removal effect.

[0004] The above patents and prior art have the following problems: The thin and long fibers in the dust and debris tend to move in the same direction under the guidance of the uniform directional airflow formed by the dust collector's suction, so that the tiny fibers are aggregated in a straight line to form a bundle structure, especially when moisture adhesion or dry friction produces electrostatic adsorption, so that the fibers in the airflow dust form bundles of fiber debris. When the bundled fiber debris is arranged in the same direction of airflow, the thin and straight fibers in the bundle structure are easily stuck in the mesh of the filter screen of the dust removal equipment and are difficult to clean, resulting in low dust removal efficiency and poor separation of debris inside the dust collector.

The height of the convex section is higher than that of the concave section. The outer ring plate and the inner ring plate are fixedly connected to the top surface of the convex section.

[0015] Another object of the present invention is to provide a method for using a combined dust collector that is easy to clean, in view of the shortcomings of the prior art, which comprises the following steps: Step 1: Extraction and dust removal: Start the driving source to discharge the air inside the extraction chamber, so that the dust and debris at the front end of the suction port are sucked into the interior of the extraction chamber; Step 2: Dispersion, pushing and kneading: When dust and debris enter the extraction chamber, they are centrifugally dispersed by the rotating dispersion column and cone tip column inside the extraction chamber, and are reciprocatedly pushed and kneaded by the processing ring and the oblique shovel ring; Step 3: Cleaning and compression: When the driving source drives the primary filter to rotate, it will drive the hanging pressure plate to reciprocate on the surface of the primary filter, so that the dirt on the surface of the primary filter is cleaned in time, and the cleaned dirt is pressed down and compressed by the hanging pressure plate; Step 4: Dust collection: The dirt compressed by the hanging pressure plate will fall into the storage chamber for storage.

[0016] Beneficial effects of the present invention: 1. The volume of the bottom cylinder and the connecting cylinder relative to the suction port becomes larger, which causes the dust and debris caused by the airflow pressure loss to settle. The rotating dispersion of the cone tip column and the dispersion column stabilizes the airflow guidance, and the reciprocating kneading of the inclined shovel ring and the processing ring disturbs the fiber bundles in the dust and debris in a disorderly manner, thereby preventing the first-level filter in the dust removal equipment from being blocked by the insertion of the fiber tip. Combined with the self-rotation of the first-level filter and the reciprocating scraping of the hanging pressure plate, the first-level filter can maintain airflow conduction under the premise of easy cleaning and self-cleaning.

[0017] 2. By starting the driving source, the driving source drives the impeller to rotate, so that negative pressure exhaust is generated inside the exhaust chamber, and the airflow at the front end of the suction port enters the exhaust chamber through the extraction chamber, thereby completing the airflow guidance for dust removal. When the airflow inside the suction port enters the extraction chamber inside the connecting tube and the bottom tube, because the internal diameter of the bottom tube and the connecting tube is larger than the diameter of the suction port, and the volume between the dispersion column, the connecting tube and the bottom tube is designed to be larger than the volume of the suction port, after the airflow enters the interior of the connecting tube and the bottom tube through the suction port, the volume of the airflow becomes larger, causing pressure loss, thereby temporarily slowing down the speed of the airflow, causing the dust and debris inside the airflow to settle, and then initially separated from the airflow.

[0018] 3. When the driving source is started, the output shaft of the driving source will also drive the plug column to rotate, and the rotation of the plug column can drive the dispersion column, the cone tip column and the primary filter to rotate, so that the large pieces of dirt or fiber clusters in the airflow entering the connecting tube will first hit the tip of the rotating cone tip column, so that they are broken by rotation and then enter the bottom tube. The airflow is decelerated by the rotating dispersion column combined with the pressure change, so that the airflow forms a certain rotational flow inside the connecting tube and the bottom tube, and the rotational flow will combine with the rotation of the dispersion column and the cone tip column to produce airflow disturbance, so that the fine dust is vibrated and suspended and extracted by the negative pressure airflow, thereby increasing the centrifugal separation effect of dust and debris passing through the outside of the dispersion column and the cone tip column, and also reducing the blockage of cleaning and separation on the outside of the dispersion column.

[0019] Fourth, the rotation of the dispersion column and the cone-tip column will also guide the slowed airflow entering the connecting tube and the bottom tube to move, so that the airflow can swirl and re-accelerate, so that the heavier fiber debris in the airflow or the small pieces of aggregated debris after the cone-tip column is broken are thrown away from the surface of the cone-tip column and the dispersion column. In this process, the dispersion column and the cone-tip column rotate to guide the airflow to obtain a re-acceleration process, so that the state of the airflow stalling due to pressure loss is guided and stabilized, and the excessive turbulence and stall of the airflow caused by the sudden diffusion of the airflow into the large volume space is reduced, so that the airflow can maintain a certain kinetic energy to guide the dust and debris inside it to continue to move.

[0020] 5. The driving source drives the plug column to rotate, which will also drive the primary filter at the bottom of the dispersion column to rotate. The rotation of the primary filter helps to centrifugally separate fiber debris or dust blocks from the airflow and throw them to the inner wall of the bottom cylinder, thereby avoiding debris clogging the filter. The filtering equipment can be self-cleaning and easy to clean, thereby reducing the frequency of maintenance. The rotating primary filter can rotate continuously to reduce the blockage of the filter holes on its surface, avoid debris blocking the airflow, and ensure that the negative pressure exhaust suction through the primary filter can be stably maintained.

[0021] 6. The reciprocating up and down motion of the docking rod will drive the processing ring and the oblique shovel ring on its top to reciprocate up and down between the dispersion column and the bottom cylinder, and the reciprocating motion of the processing ring and the oblique shovel ring can reciprocately change the position of dust and debris between them and the inner wall of the bottom cylinder. When encountering agglomerated dust blocks or fiber clusters, the reciprocating processing ring and the oblique shovel ring will break the mutual entanglement and aggregation of the debris, so that the debris is reciprocated from bundles or lines into small pieces or loose states that are easier to disperse, reducing the risk of agglomeration in a humid environment. The reciprocating motion of the processing ring and the oblique shovel ring and the rotation of the dispersion column can form multi-directional disturbances to make the fibers continuously subjected to forces in different directions. These forces can be longitudinal or rotational forces, which make the fibers lose their stable arrangement direction in the flow, so that the fibers cannot maintain a stable straight line state, but present a random and twisted shape, which makes them move in a disordered and curved state after being disturbed in the airflow, thereby avoiding the situation where they rush towards the filter in a single direction.

[0022] 7. The inclined shovel ring is conical in shape. When its tip is pushed toward the suction port, it will scoop up the airflow that guides it toward the suction port and move it along the inclined surface of the cone tip column surface toward the processing ring and the bottom cylinder, thereby increasing the pressure of the airflow and combining with the rotation of the dispersion column to produce centrifugal swing, so that the debris between the bottom cylinder and the dispersion column is scooped up and pressurized by the inclined shovel ring and then pushed and rubbed back and forth by the processing ring. When the tip of the cone tip column approaches the suction port, the inclined surface of its surface will not push too much airflow to counteract the airflow entering the suction port, thereby ensuring the stability of the airflow and preventing debris from gathering at the tip of the cone tip column. The reciprocating cone tip column will also shovel up the fiber debris entangled on its surface as the dispersion column rotates, so that the gap between the dispersion column and the bottom cylinder remains relatively stable.

[0023] 8. Install a heating resistance wire inside the bottom cylinder corresponding to the dispersion column, so that the reciprocating processing ring and the cone tip column can reciprocate and expand the dust and debris between it and the bottom cylinder to the inner wall surface of the bottom cylinder. The heated resistance wire heats the moisture inside the dust and debris to be diffused and dried, so that the dust and debris can be protected from the influence of humid water vapor during dust removal, and the volume of the dust and debris can be more dispersed by reciprocating motion.

[0024] 9. When the docking rod reciprocates up and down, it will drive the hanging pressure plate at the bottom of the lower pressure rod to move back and forth on the surface of the first-level filter through the cross plate and the lower pressure rod, so that the reciprocating hanging pressure plate will scrape the dirt on the surface of the first-level filter, and scrape up the dirt on the surface of the first-level filter during the rise of the hanging pressure plate and throw it out as the first-level filter rotates, thereby increasing the mobility of dust attached to the surface of the first-level filter, avoiding dust and debris from adhering to the surface of the first-level filter for a long time, and the descent of the hanging pressure plate will cause the dust and debris on the surface of the first-level filter to be pressed down by the hanging pressure plate to the inside of the storage chamber for compression and collection, thereby ensuring that the dust and debris on the outside of the first-level filter will not contact the first-level filter excessively, making it difficult for the surface of the dust and debris to be entangled with the fibers in the dust and debris, thereby ensuring the filtering and air guiding effect of the first-level filter.

The movable cavity 2031 is internally provided with two storage cavities 2032 corresponding to the hanging pressure plate 2015, and a ball is provided between the storage cavity 2032 and the movable cavity 2031. The ball can be arbitrarily embedded in the surface of the storage cavity 2032 or the movable cavity 2031, and a docking rod 2016 is provided between the two storage cavities 2032.

[0035] like Figure 6-11 As shown, a secondary filter 20231 is arranged inside the primary filter 2022, a plug post 2023 is rotatably arranged in the middle of the secondary filter 20231, a dispersion column 202 is installed on the top of the plug post 2023, the secondary filter 20231 is fixedly connected to the top of the inner ring plate 2033, an exhaust cavity 205 is arranged at the bottom of the secondary filter 20231, the driving source 1022 is arranged inside the exhaust cavity 205, the output shaft of the driving source 1022 is fixedly connected to the plug post 2023, and the secondary filter 20231 is preferably a composite air filter of mixed activated carbon; The rolling element 20162 is rollingly set on the top surface of the traction sleeve 204, and the traction sleeve 204 includes two concave sections 2041 and two convex sections 2043 and a connecting section 2042 connected between the concave sections 2041 and the convex sections 2043, the height of the convex section 2043 is higher than that of the concave section 2041, the outer ring plate 203 and the inner ring plate 2033 are fixedly connected to the top surface of the convex section 2043, the two concave sections 2041 and the two convex sections 2043 are symmetrical about the center line of the driving source 1022, and the outer ring plate 203 and the traction sleeve 204 are fixedly connected to the inner wall of the bottom cylinder 102.

[0036] Operation process: By starting the driving source 1022, the driving source 1022 drives the impeller 10221 to rotate, so that negative pressure exhaust is generated inside the exhaust chamber 205, and the airflow at the front end of the suction port 105 enters the exhaust chamber 205 through the extraction chamber 103, thereby completing the airflow guidance for dust removal. When the airflow inside the suction port 105 enters the extraction chamber 103 inside the connecting tube 104 and the bottom tube 102, because the internal diameter of the bottom tube 102 and the connecting tube 104 is larger than the diameter of the suction port 105, and the volume between the dispersion column 202 and the connecting tube 104 and the bottom tube 102 is larger than the volume of the suction port 105 through design, after the airflow enters the connecting tube 104 and the bottom tube 102 through the suction port 105, the volume of the airflow becomes larger, resulting in pressure loss, so that the speed of the airflow is temporarily slowed down, so that the dust and debris inside the airflow are settled, and then preliminarily separated from the airflow; When the driving source 1022 is started, the output shaft of the driving source 1022 will also drive the plug column 2023 to rotate. The rotation of the plug column 2023 can drive the dispersion column 202, the cone tip column 2021 and the primary filter screen 2022 to rotate, so that the large pieces of dirt or fiber clusters in the airflow entering the connecting tube 104 will first hit the tip of the rotating cone tip column 2021, so that they are rotated and broken before entering the bottom tube 102. The airflow is decelerated by the rotating dispersion column 202 combined with the pressure change, so that the airflow forms a certain rotation flow inside the connecting tube 104 and the bottom tube 102, and the rotation flow will combine with the rotation centrifugation of the dispersion column 202 and the cone tip column 2021 to produce airflow disturbance, so that the fine dust is vibrated and suspended and extracted and taken away by the negative pressure airflow, thereby increasing the centrifugal separation effect of dust and debris passing through the outside of the dispersion column 202 and the cone tip column 2021, and also reducing the blockage of the cleaning and separation outside the dispersion column 202. The rotation of the dispersion column 202 and the cone tip column 2021 will also guide the slowed airflow entering the connecting tube 104 and the bottom tube 102 to move, so that the airflow swirls and accelerates the airflow again, so that the heavier fiber debris in the airflow or the small pieces of aggregated debris broken by the cone tip column 2021 are thrown away from the surface of the cone tip column 2021 and the dispersion column 202. In this process, the dispersion column 202 and the cone tip column 2021 rotate to guide the airflow to obtain a re-acceleration process, so that the state of the airflow stalling due to pressure loss is guided and stabilized, and the excessive turbulence and stalling of the airflow caused by the sudden diffusion of the airflow into the large volume space is reduced, so that the airflow can maintain a certain kinetic energy to guide the dust and debris inside it to continue to move; The driving source 1022 drives the plug column 2023 to rotate, which also drives the primary filter 2022 at the bottom of the dispersion column 202 to rotate. The rotation of the primary filter 2022 helps to centrifugally separate fiber debris or dust blocks from the airflow and throw them to the inner wall of the bottom cylinder 102, thereby preventing debris from clogging the filter, so that the filtering device can be self-cleaning and easy to clean, thereby reducing the frequency of maintenance. The rotating primary filter 2022 can continuously rotate to reduce the clogging of the filter holes on its surface, avoid debris from blocking the airflow, and ensure that the negative pressure exhaust suction through the primary filter 2022 can be stably maintained. The rotation of the primary filter screen 2022 drives the docking rod 2016 movably connected inside the through-plate 20221 to make a circular motion along the annular groove 2034 through the through-plate 20221 installed on the outside thereof. When the docking rod 2016 makes a circular motion along the annular groove 2034, the rolling element 20162 at the bottom thereof moves on the top surface of the traction sleeve 204. Then, when the rolling element 20162 moves to the concave section 2041 in the traction sleeve 204, the height of the docking rod 2016 decreases. When the connecting rod 2016 moves to the raised section 2043, the height of the connecting rod 2016 rises, and when the rolling element 20162 moves to the connecting section 2042, the rolling element 20162 is transferred between the concave section 2041 and the raised section 2043, and when the connecting rod 2016 makes a circular motion along the annular groove 2034, the rolling element 20162 moves on the top of the concave section 2041, the connecting section 2042 and the raised section 2043, so that the connecting rod 2016 makes an up-and-down reciprocating motion with a height change; The reciprocating motion of the docking rod 2016 will drive the processing ring 201 and the oblique shovel ring 2011 on the top thereof to reciprocate between the dispersion column 202 and the bottom cylinder 102. The reciprocating motion of the processing ring 201 and the oblique shovel ring 2011 can reciprocate and change the position of dust and debris between them and the inner wall of the bottom cylinder 102. When encountering agglomerated dust blocks or fiber clusters, the reciprocating processing ring 201 and the oblique shovel ring 2011 will break the mutually entangled aggregation state of the debris, so that the debris is reciprocated from bundles or lines into small pieces or loose states that are easier to disperse. , reducing the risk of agglomeration in a humid environment, and the reciprocating motion of the processing ring 201 and the oblique shovel ring 2011 and the rotation of the dispersion column 202 can form multi-directional disturbances so that the fibers are continuously subjected to forces in different directions. These forces can be longitudinal or rotational forces, which make the fibers lose their stable arrangement direction in the flow, and the fibers cannot maintain a stable straight state, but present a random, twisted shape, which makes them move in a disordered, curved state after being disturbed in the airflow, thereby avoiding the situation where they rush toward the filter in a single direction.

[0037] The inclined shovel ring 2011 is conical in shape, and when its tip is pushed toward the suction port 105, it will scoop up the airflow that guides it toward the suction port 105 and move it along the inclined surface of the surface of the cone tip column 2021 between the processing ring 201 and the bottom cylinder 102, thereby increasing the pressure of the airflow and combining with the rotation of the dispersion column 202 to produce centrifugal swing, so that the debris between the bottom cylinder 102 and the dispersion column 202 is scooped up and pressurized by the inclined shovel ring 2011 and then pushed and kneaded back and forth by the processing ring 201, and when the tip of the cone tip column 2021 approaches the suction port 105, the inclined surface of its surface will not push too much airflow to counteract the airflow entering the suction port 105, thereby ensuring the stability of the airflow and preventing debris from gathering at the tip of the cone tip column 2021, and the reciprocating cone tip column 2021 will also shovel fiber debris that is entangled on its surface as the dispersion column 202 rotates, so that the gap between the dispersion column 202 and the bottom cylinder 102 remains relatively stable; Of course, a planetary gear can also be installed on the outside of the primary filter 2022, that is, an inner gear ring 20224 can be installed on the outside of the primary filter 2022, so that the inner gear ring 20224 is meshed and transmitted with the transmission gear 20223 and the outer gear ring 20222, so that the penetration plate 20221 is installed on the surface of the outer gear ring 20222, and the transmission gear 20223 is fixed in a rotation position on the surface of the shell 20225 at the bottom, and the outer gear ring 20222 is rotatably installed between the upper and lower shells 20225 and rotates relative to the upper and lower shells 20225, so that the top shell 20225 is sleeved on the surface of the primary filter 2022, and the bottom shell 20225 is fixedly installed on the top of the inner ring plate 2033, so that the number of teeth of the inner gear ring 20224 is less than the number of teeth of the outer gear ring 20222, so that the penetration plate 20221 and the outer gear ring 20222 are reduced in rotation relative to the primary filter 2022.

[0038] Of course, a heating resistance wire can also be installed inside the bottom cylinder 102 corresponding to the dispersion column 202, so that the reciprocating processing ring 201 and the cone tip column 2021 can reciprocate and spread the dust and debris between it and the bottom cylinder 102 to the inner wall surface of the bottom cylinder 102, and the heated resistance wire is heated to spread and diffuse the moisture inside the dust and debris to dry, so that the dust and debris can be prevented from being affected by moisture during dust removal, and the volume of the dust and debris can be rubbed and dispersed by the reciprocating motion; When the docking rod 2016 reciprocates up and down, it will drive the hanging pressure plate 2015 at the bottom of the lower pressure rod 2014 to move back and forth on the surface of the primary filter 2022 through the cross plate 2013 and the lower pressure rod 2014, so that the reciprocating hanging pressure plate 2015 will scrape the dirt on the surface of the primary filter 2022, and scrape the dirt on the surface of the primary filter 2022 during the rise of the hanging pressure plate 2015 and throw it out as the primary filter 2022 rotates, thereby increasing the primary filter 2022. The mobility of dust attached to the surface prevents dust and debris from adhering to the surface of the primary filter 2022 for a long time, and the descent of the hanging pressure plate 2015 will cause the dust and debris on the surface of the primary filter 2022 to be pressed down by the hanging pressure plate 2015 to the inside of the storage chamber 2032 for compression and collection, thereby ensuring that dust and debris on the outside of the primary filter 2022 will not excessively contact the primary filter 2022, making it difficult for the surface of the dust and debris to be entangled with fibers in the dust and debris, thereby ensuring the filtering and air guiding effect of the primary filter 2022.

[0039] The present invention can also be scaled up in equal proportions, and the equipment can be assembled and fixed by means of a rack to serve as a fixed air purifier and dust collector.

[0040] In summary: the present invention increases the volume of the bottom cylinder 102 and the connecting cylinder 104 relative to the suction port 105, thereby causing the dust and debris generated by the airflow pressure loss to settle, and through the rotation and dispersion of the cone-tip column 2021 and the dispersion column 202 to stabilize the airflow guidance and the reciprocating kneading of the inclined shovel ring 2011 and the processing ring 201, the fiber bundle state in the dust and debris is disorderly disturbed, thereby preventing the first-level filter screen in the dust removal equipment from being blocked by the insertion of the fiber tip, and combined with the self-rotation of the first-level filter screen 2022 and the reciprocating scraping and pressing of the hanging pressure plate 2015, the first-level filter screen 2022 can maintain airflow conduction under the premise of easy cleaning and self-cleaning.
