Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and in particular to a convenient-to-clean combined dust collector and its usage method. Background Technology

[0002] Dust collectors can be divided into two main categories: handheld portable and stationary. They have different characteristics depending on the usage needs and scenarios. Handheld portable dust collectors are small, lightweight and easy to carry, making them suitable for cleaning small environments. Stationary dust collectors are usually larger and installed in specific locations, mainly used for dust removal in industrial sites or large areas.

[0003] Chinese patent CN201821562480.0 discloses a combined dust collector, which includes an air intake port for drawing in air, an air outlet for discharging air, a first dust collector and a second dust collector for dust removal, and a fan for compressing and conveying air. The amount of air drawn in through the air intake port is greater than the amount of air discharged through the air outlet. The air intake port, air outlet, and second dust collector are connected to the outside environment. The air intake port is connected to both the first and second dust collectors. The first dust collector is connected to the fan, and the fan is connected to the air outlet. The combined dust collector described above has the advantages of high dust removal efficiency and good dust removal effect.

[0004] The aforementioned patents and prior art have the following problems:

[0005] When fine fibers in dust and debris are guided by the uniform airflow generated by the dust collector, they tend to move in the same direction, causing the fine fibers to aggregate in a straight line and form a bundle structure. This is especially true when moisture adheres or when dry friction generates electrostatic adsorption, which causes the fibers in the dust in the airflow to form bundles of fiber debris. When these bundles of fiber debris are arranged in the same direction by the airflow, the fine fibers in the straight line within the bundle structure are easily stuck into the mesh of the dust collector's filter screen and are difficult to clean, resulting in low dust removal efficiency and poor separation of debris inside the dust collector. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A convenient and easy-to-clean modular dust collector includes:

[0009] The dust removal body includes a control handle. The top of the control handle is sequentially provided with a bottom cylinder, a connecting cylinder, and a suction port. The bottom cylinder, the connecting cylinder, and the suction port are internally connected to a suction chamber.

[0017] Preferably, a slanted shovel ring is installed on the opposite side of the processing ring and the suction port. The slanted shovel ring is conical in shape, and its center is slidably sleeved on the surface of the dispersion column.

[0018] The processing ring is slidably fitted onto the surface of the dispersion column.

[0019] Preferably, a primary filter screen is fixedly connected to the bottom of the dispersion column, the surface of the primary filter screen is uniformly provided with filter holes, and through plates are symmetrically fixedly connected to the surface of the primary filter screen;

[0020] The primary filter screen is movably inserted into the top surface of the inner ring plate. An outer ring plate is provided on the outside of the inner ring plate. A movable cavity is provided between the inner ring plate and the outer ring plate. A ring groove is provided at the bottom of the movable cavity.

[0021] Preferably, the bottom of the processing ring is symmetrically provided with movable rods, the middle of the movable rods is horizontally fixedly connected to a horizontal plate, the movable rods are fixedly inserted through the horizontal plate and the connecting rod, and the bottom of the outer side of the horizontal plate is fixedly connected to the hanging plate through a pressing rod;

[0022] The connecting rod is movably connected through the through plate and the rolling element.

[0023] Preferably, the docking rod is movably engaged inside the annular groove, and an elastic element is sleeved on the surface of the docking rod;

[0024] The movable cavity has two storage chambers corresponding to the hanging pressure plate. A ball bearing is provided between the storage chamber and the movable cavity, and a connecting rod is provided between the two storage chambers.

[0025] Preferably, a secondary filter is provided inside the primary filter screen, a post is rotatably provided in the middle of the secondary filter screen, a dispersing post is installed on the top of the post, the secondary filter screen is fixedly connected to the top of the inner ring plate, an exhaust chamber is provided at the bottom of the secondary filter screen, the drive source is located inside the exhaust chamber, and the output shaft of the drive source is fixedly connected to the post.

[0026] The rolling element is rolled on the top surface of the traction sleeve. The traction sleeve includes two concave sections and two convex sections, as well as a connecting section connecting the concave sections and the convex sections. The height of the convex sections is higher than that of the concave sections. The outer ring plate and the inner ring plate are fixedly connected to the top surface of the convex sections.

[0027] Another objective of this invention is to address the shortcomings of existing technologies by providing a convenient method for using a combined dust collector, comprising the following steps:

[0028] Step 1, Dust Removal: Start the drive source to expel the air inside the extraction chamber, so that the dust and debris at the front of the suction port are sucked into the extraction chamber.

[0029] Step 2, Dispersion and Kneading: When dust and debris enter the extraction chamber, they are centrifugally dispersed by the rotating dispersion column and cone-shaped column inside the extraction chamber, and then kneaded by the reciprocating pushing of the processing ring and the inclined shovel ring.

[0030] Step 3, Cleaning and Compression: When the drive source rotates the primary filter screen, it will cause the pressure plate to move back and forth on the surface of the primary filter screen, so that the dirt on the surface of the primary filter screen is cleaned in time, and the cleaned dirt is pressed down and compressed by the pressure plate.

[0031] Step 4: Dust Collection: The dirt compressed by the pressure plate will fall into the storage chamber for storage.

[0032] The beneficial effects of this invention are:

[0033] 1. The increased volume of the bottom cylinder and connecting cylinder relative to the suction port causes airflow pressure loss, resulting in the settling of dust and debris. The rotation of the cone-shaped column and the dispersing column stabilizes and guides the airflow, while the reciprocating rubbing of the inclined shovel ring and the processing ring disturbs the disordered fibrous bundles in the dust and debris. This prevents the primary filter screen in the dust removal equipment from being blocked by fiber tips. Combined with the self-rotation of the primary filter screen and the reciprocating scraping of the hanging plate, the primary filter screen maintains airflow conduction while being easy to clean and self-cleaning.

[0034] 2. By starting the drive source, the impeller is rotated, creating negative pressure exhaust inside the exhaust chamber. This allows the airflow at the front of the suction port to enter the exhaust chamber through the extraction chamber, thus guiding the dust removal airflow. When the airflow inside the suction port enters the extraction chamber inside the connecting cylinder and the bottom cylinder, because the inner diameter of the bottom cylinder and the connecting cylinder is larger than the diameter of the suction port, and because the volume between the dispersion column, the connecting cylinder, and the bottom cylinder is larger than the volume of the suction port, the airflow enters the connecting cylinder and the bottom cylinder through the suction port. This increases the volume of the airflow, causing pressure loss and temporarily slowing down the airflow speed. This allows the dust and debris inside the airflow to settle and be initially separated from the airflow.

[0035] Third, when the drive source starts, the output shaft of the drive source will also drive the insertion column to rotate. The rotation of the insertion column can drive the dispersion column, the cone tip column, and the first-stage filter screen to rotate. Large pieces of dirt or fiber clumps in the airflow entering the connecting cylinder will first hit the tip of the rotating cone tip column, causing them to be broken up by rotation before entering the bottom cylinder. The rotating dispersion column, combined with the deceleration of the airflow caused by pressure changes, creates a certain rotational flow inside the connecting cylinder and the bottom cylinder. This rotational flow, combined with the centrifugal force of the rotation of the dispersion column and the cone tip column, generates airflow disturbance, causing fine dust to be vibrated and suspended and then drawn away by the negative pressure airflow. This increases the centrifugal separation effect of dust and debris passing through the outer side of the dispersion column and the cone tip column, while also reducing the clogging of the outer side of the dispersion column.

[0036] Fourth, the rotation of the dispersion column and the cone tip column will also guide the slowed airflow into the connecting cylinder and the bottom cylinder, causing the airflow to swirl and even accelerate again. This will cause heavier fiber debris or small aggregates of debris from the broken cone tip column to be thrown off the surface of the cone tip column and the dispersion column. During this process, the rotation of the dispersion column and the cone tip column guides the airflow to obtain a re-acceleration process, which guides and stabilizes the airflow from the state of stalling due to pressure loss. This reduces the excessive turbulence and stalling of the airflow caused by sudden diffusion into the large volume space, allowing the airflow to maintain a certain kinetic energy to guide the dust and debris inside to continue to move.

[0037] 5. The drive source rotates the insertion column, which in turn rotates the primary filter screen at the bottom of the dispersion column. The rotation of the primary filter screen helps to centrifugally separate fibrous debris or dust particles from the airflow and throw them onto the inner wall of the bottom cylinder, thereby preventing debris from clogging the filter screen. This allows the filtration equipment to achieve self-cleaning and easy cleaning, thus reducing the frequency of maintenance. The rotating primary filter screen can rotate continuously to reduce the clogging of its surface filter holes, preventing debris from obstructing the airflow and ensuring that the negative pressure exhaust suction force through the primary filter screen can be maintained stably.

[0038] VI. The reciprocating motion of the connecting rod drives the top processing ring and the inclined shovel ring to reciprocate between the dispersing column and the bottom cylinder. The reciprocating motion of the processing ring and the inclined shovel ring can repeatedly change the position of dust and debris between them and the inner wall of the bottom cylinder. When encountering clumps of dust or fiber clusters, the reciprocating processing ring and the inclined shovel ring will break the entangled and aggregated state of the debris, causing the debris to be repeatedly kneaded from bundles or lines into smaller pieces or a looser state that is easier to disperse. This reduces the risk of it clumping together in a humid environment. Furthermore, the reciprocating motion of the processing ring and the inclined shovel ring and the rotation of the dispersing column can create multi-directional disturbances, causing the fibers to be continuously subjected to forces in different directions. These forces can be longitudinal or rotational, causing the fibers to lose their stable alignment direction in the flow. The fibers cannot maintain a stable straight state, but instead exhibit a random and twisted shape. This causes them to move in a disordered and bent state after being disturbed in the airflow, thus avoiding the situation where they rush towards the filter screen in a single direction.

[0039] 7. The slanted shovel ring is conical in shape. When its tip is pushed toward the suction port, it scoops up the airflow that guides it toward the suction port and moves it along the inclined surface of the cone tip between the treatment ring and the bottom cylinder. This increases the pressure of the airflow and, combined with the centrifugal force generated by the rotation of the dispersion column, causes the debris between the bottom cylinder and the dispersion column to be scooped up and pressurized by the slanted shovel ring and then repeatedly pushed and rubbed by the treatment ring. When the tip of the cone tip approaches the suction port, its inclined surface will not push too much airflow to oppose the airflow entering the suction port, thus ensuring the stability of the airflow and preventing debris from accumulating at the tip of the cone tip. The reciprocating cone tip also scoops up the fibrous debris that wraps around its surface as the dispersion column rotates, keeping the gap between the dispersion column and the bottom cylinder relatively stable.

[0040] 8. Install heating resistance wires inside the bottom cylinder corresponding to the dispersion column. This allows the reciprocating processing ring and cone-shaped column to repeatedly spread the dust and debris between the bottom cylinder and the bottom cylinder to the inner wall of the bottom cylinder. The heated resistance wires then spread and dry the moisture inside the dust and debris, thus preventing the dust and debris from being affected by moisture during dust removal. This also allows the dust and debris to be more dispersed by the reciprocating motion.

[0041] 9. When the connecting rod moves up and down, it drives the hanging plate at the bottom of the lowering rod to move back and forth on the surface of the primary filter screen through the horizontal plate and the lowering rod. This causes the reciprocating hanging plate to scrape the dirt on the surface of the primary filter screen. As the hanging plate rises, it scrapes up the dirt on the surface of the primary filter screen and throws it out with the rotation of the primary filter screen. This increases the mobility of dust adhering to the surface of the primary filter screen and prevents dust and debris from adhering to the surface of the primary filter screen for a long time. Furthermore, the descent of the hanging plate will cause the dust and debris on the surface of the primary filter screen to be compressed and collected inside the storage cavity. This ensures that the dust and debris on the outside of the primary filter screen will not come into excessive contact with the primary filter screen, making it less likely for fibers in the dust and debris to become entangled on its surface, thus ensuring the filtering and air guiding effect of the primary filter screen.

Detailed Implementation Example 1

[0059] like Figure 1-12 As shown, a convenient-to-clean combined dust collector includes:

[0060] The dust removal body 1 includes a control handle 101. The top of the control handle 101 is sequentially provided with a bottom cylinder 102, a connecting cylinder 104, and a suction port 105. The bottom cylinder 102, the connecting cylinder 104, and the suction port 105 are internally connected to a suction chamber 103. The surface of the control handle 101 is equipped with a button for starting and stopping the drive source 1022 and is electrically connected to it.

[0061] Processing unit 2 is provided inside the extraction cavity 103;

[0062] The processing unit 2 includes a dispersion column 202 and a primary filter screen 2022 rotatably disposed inside the extraction chamber 103.

The conical tip column 2021 is fixedly connected to the top of the dispersing column 202.

[0065] There is a gap between the processing ring 201 and the bottom cylinder 102.

[0066] like Figure 1-6 As shown, a slanted shovel ring 2011 is installed on the opposite side of the processing ring 201 and the suction port 105. The slanted shovel ring 2011 is conical in shape, and the center of the slanted shovel ring 2011 is slidably sleeved on the surface of the dispersion column 202.

[0067] The processing ring 201 is slidably sleeved on the surface of the dispersion column 202.

[0068] like Figure 7 As shown, the bottom cylinder 102 and the connecting cylinder 104 are fixedly connected on the opposite side by a support plate 1021 and a drive source 1022. The drive source 1022 is preferably a servo motor or a geared motor, which is controlled by a PLC and powered by an external energy source.

[0069] An impeller 10221 is mounted on the output shaft of the drive source 1022.

[0070] like Figure 5-10 As shown, a primary filter screen 2022 is fixedly connected to the bottom of the dispersion column 202. The surface of the primary filter screen 2022 is uniformly provided with filter holes, and a through plate 20221 is symmetrically fixedly connected to the surface of the primary filter screen 2022.

[0071] The primary filter screen 2022 is movably inserted into the top surface of the inner ring plate 2033, that is, the primary filter screen 2022 is inserted into the top of the inner ring plate 2033 and ball bearings are embedded between the primary filter screen 2022 and the inner ring plate 2033. An outer ring plate 203 is provided on the outside of the inner ring plate 2033. A movable cavity 2031 is provided between the inner ring plate 2033 and the outer ring plate 203. An annular groove 2034 is provided at the bottom of the movable cavity 2031.

[0072] like Figure 6-9 As shown, the bottom of the processing ring 201 is symmetrically provided with movable rods 2012, and a horizontal plate 2013 is horizontally fixedly connected to the middle of the movable rod 2012. The movable rod 2012 is fixedly inserted through the horizontal plate 2013 and the connecting rod 2016. The bottom of the outer side of the horizontal plate 2013 is fixedly connected to the hanging plate 2015 through the pressing rod 2014.

[0073] The connecting rod 2016 is fixedly connected to the through plate 20221 and the rolling element 20162, and the rolling element 20162 is preferably a universal ball.

[0074] The docking rod 2016 is movably engaged inside the annular groove 2034. An elastic element 20161 is sleeved on the surface of the docking rod 2016, and the ring at the bottom of the elastic element 20161 is fixedly sleeved on the surface of the docking rod 2016, and the ring does not contact the bottom of the movable cavity 2031. The top of the elastic element 20161 is fixedly connected to the bottom of the through plate 20221. The elastic element 20161 is preferably a spring.

[0075] The movable cavity 2031 has two storage cavities 2032 corresponding to the hanging plate 2015. A ball bearing is provided between the storage cavity 2032 and the movable cavity 2031. The ball bearing can be arbitrarily embedded in the surface of the storage cavity 2032 or the movable cavity 2031. A connecting rod 2016 is provided between the two storage cavities 2032. A vertical plate extends downward from the outer side of the through plate 20221. The vertical plate contacts the side of the storage cavity 2032 and is used to push the storage cavity 2032 to move inside the movable cavity 2031.

[0076] like Figure 6-11As shown, a secondary filter 20231 is provided inside the primary filter 2022. A column 2023 is rotatably provided in the middle of the secondary filter 20231. A dispersion column 202 is installed on the top of the column 2023. The secondary filter 20231 is fixedly connected to the top of the inner ring plate 2033. An exhaust chamber 205 is provided at the bottom of the secondary filter 20231. The drive source 1022 is located inside the exhaust chamber 205. The output shaft of the drive source 1022 is fixedly connected to the column 2023. The secondary filter 20231 is preferably a composite air filter with mixed activated carbon.

[0077] The rolling element 20162 is rotatably disposed on the top surface of the traction sleeve 204. The traction sleeve 204 includes two concave sections 2041 and two protruding sections 2043, as well as a connecting section 2042 connecting the concave sections 2041 and the protruding sections 2043. The height of the protruding sections 2043 is higher than that of the concave sections 2041. The outer ring plate 203 and the inner ring plate 2033 are fixedly connected to the top surface of the protruding sections 2043. The two concave sections 2041 and the two protruding sections 2043 are symmetrical about the centerline of the driving source 1022. The outer ring plate 203 and the traction sleeve 204 are both fixedly connected to the inner wall of the bottom cylinder 102.

[0078] Operation process:

[0079] By activating the drive source 1022, the impeller 10221 is rotated, causing a negative pressure exhaust inside the exhaust chamber 205. This allows the airflow at the front end of the suction port 105 to enter the interior of the exhaust chamber 205 through the extraction chamber 103, thus completing the airflow guidance for dust removal. When the airflow inside the suction port 105 enters the extraction chamber 103 inside the connecting cylinder 104 and the bottom cylinder 102, because the internal diameter of the bottom cylinder 102 and the connecting cylinder 104 is larger than the diameter of the suction port 105, and because the volume between the dispersion column 202, the connecting cylinder 104, and the bottom cylinder 102 is larger than the volume of the suction port 105, the airflow enters the interior of the connecting cylinder 104 and the bottom cylinder 102 through the suction port 105. This increases the volume of the airflow, causing pressure loss and temporarily slowing down the airflow speed. This allows the dust and debris inside the airflow to settle and be initially separated from the airflow.

[0080] When the drive source 1022 is started, the output shaft of the drive source 1022 will also drive the insertion post 2023 to rotate. The rotation of the insertion post 2023 can drive the dispersion post 202, the cone tip post 2021, and the first-stage filter screen 2022 to rotate. Large pieces of dirt or fiber clumps in the airflow entering the connecting cylinder 104 will first hit the tip of the rotating cone tip post 2021, causing them to be broken up by rotation before entering the bottom cylinder 102. The rotating dispersion post 202, combined with the airflow deceleration caused by pressure changes, will create a certain rotational flow in the connecting cylinder 104 and the bottom cylinder 102. This rotational flow will combine with the centrifugal rotation of the dispersion post 202 and the cone tip post 2021 to generate airflow disturbance, causing fine dust to be vibrated and suspended and then drawn away by the negative pressure airflow. This will increase the centrifugal separation effect of dust and debris passing through the outer side of the dispersion post 202 and the cone tip post 2021, while also reducing the clogging of the outer side of the dispersion post 202.

[0081] The rotation of the dispersion column 202 and the cone tip column 2021 also guides the slowed airflow into the connecting cylinder 104 and the bottom cylinder 102, causing the airflow to swirl and even accelerate again. This causes heavier fiber debris or small aggregates of debris broken by the cone tip column 2021 to be thrown off the surface of the cone tip column 2021 and the dispersion column 202. During this process, the rotation of the dispersion column 202 and the cone tip column 2021 guides the airflow to obtain a re-acceleration process, so that the airflow stalls due to pressure loss and is stabilized. This reduces the excessive turbulence and stall caused by the sudden diffusion of the airflow into the large volume space, allowing the airflow to maintain a certain kinetic energy to guide the dust and debris inside to continue moving.

[0082] The drive source 1022 drives the insertion column 2023 to rotate, which in turn drives the primary filter screen 2022 at the bottom of the dispersion column 202 to rotate. The rotation of the primary filter screen 2022 helps to centrifugally separate fibrous debris or dust from the airflow and throw them toward the inner wall of the bottom cylinder 102, thereby preventing debris from clogging the filter screen. This allows the filtration equipment to achieve self-cleaning and easy cleaning, thus reducing the frequency of maintenance. The rotating primary filter screen 2022 can rotate continuously to reduce the clogging of its surface filter holes, prevent debris from obstructing the airflow, and ensure that the negative pressure exhaust suction force through the primary filter screen 2022 can be stably maintained.

[0083] The rotation of the primary filter 2022 causes the connecting rod 2016, which is movably connected inside the through plate 20221 mounted on its outer side, to move in a circular motion along the annular groove 2034. This circular motion of the connecting rod 2016 along the annular groove 2034 causes the rolling element 20162 at its bottom to move on the top surface of the traction sleeve 204. When the rolling element 20162 moves to the concave section 2041 in the traction sleeve 204, the height of the connecting rod 2016 decreases. When the 62 moves to the raised section 2043, the height of the docking rod 2016 will rise. When the rolling element 20162 moves to the connecting section 2042, the rolling element 20162 moves between the concave section 2041 and the raised section 2043. When the docking rod 2016 moves in a circle along the annular groove 2034, the rolling element 20162 moves at the top of the concave section 2041, the connecting section 2042 and the raised section 2043, thereby causing the docking rod 2016 to make up-down reciprocating motion with varying height.

[0084] The reciprocating motion of the connecting rod 2016 causes the top processing ring 201 and the inclined shovel ring 2011 to reciprocate between the dispersing column 202 and the bottom cylinder 102. This reciprocating motion of the processing ring 201 and the inclined shovel ring 2011 alters the position of dust and debris between them and the inner wall of the bottom cylinder 102. When encountering clumps of dust or fibers, the reciprocating motion of the processing ring 201 and the inclined shovel ring 2011 breaks up the tangled and aggregated state of the debris, repeatedly kneading it from a bundle or thread-like shape into smaller, more easily dispersed pieces or a looser state. This reduces the risk of clumping in humid environments. The reciprocating motion of the treatment ring 201 and the inclined shovel ring 2011, along with the rotation of the dispersion column 202, creates multi-directional disturbances that subject the fibers to forces in different directions. These forces can be longitudinal or rotational, causing the fibers to lose their stable alignment during flow. This prevents the fibers from maintaining a stable straight line and instead results in a random, twisted shape. Consequently, after being disturbed in the airflow, they move in a disordered, bent state, thus preventing them from rushing towards the filter screen in a single direction.

[0085] The slanted shovel ring 2011 is conical in shape. When its tip is pushed toward the suction port 105, it shovels up the airflow that guides it toward the suction port 105 and moves it along the inclined surface of the cone tip 2021 between the processing ring 201 and the bottom cylinder 102. This increases the pressure of the airflow and, combined with the centrifugal swing generated by the rotation of the dispersion column 202, causes the debris between the bottom cylinder 102 and the dispersion column 202 to be scooped up and pressurized by the slanted shovel ring 2011 and then repeatedly pushed and rubbed by the processing ring 201. When the tip of the cone tip 2021 approaches the suction port 105, its inclined surface will not push too much airflow to oppose the airflow entering the suction port 105, thus ensuring the stability of the airflow and preventing debris from accumulating at the tip of the cone tip 2021. The reciprocating cone tip 2021 also shovels up the fibrous debris that wraps around its surface as the dispersion column 202 rotates, keeping the gap between the dispersion column 202 and the bottom cylinder 102 relatively stable.

[0086] Alternatively, a planetary gear can be added to the outside of the primary filter 2022, i.e., an internal gear ring 20224 can be added to the outside of the primary filter 2022. The internal gear ring 20224 is driven by the transmission gear 20223 and the external gear ring 20222. The through plate 20221 is installed on the surface of the external gear ring 20222, and the transmission gear 20223 is fixedly rotatably set on the surface of the bottom housing 20225. The external gear ring 20222 is rotatably installed between the upper and lower housings 20225 and rotates relative to the upper and lower housings 20225. The top housing 20225 is fitted onto the surface of the primary filter 2022, and the bottom housing 20225 is fixedly installed on the top of the inner ring plate 2033. The number of teeth of the internal gear ring 20224 is less than the number of teeth of the external gear ring 20222, so that the through plate 20221 and the external gear ring 20222 rotate relative to the primary filter 2022 with reduced speed.

[0087] 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 repeatedly spread the dust and debris between them and the bottom cylinder 102 to the inner wall surface of the bottom cylinder 102. The heated resistance wire can then spread and dry the moisture inside the dust and debris, thus preventing the dust and debris from being affected by moisture during dust removal, and allowing the volume of the dust and debris to be more dispersed by the reciprocating motion.

[0088] When the connecting rod 2016 moves up and down, it drives the hanging plate 2015 at the bottom of the lowering rod 2014 to move back and forth on the surface of the primary filter screen 2022 via the horizontal plate 2013 and the lowering rod 2014. This causes the reciprocating hanging plate 2015 to scrape away dirt from the surface of the primary filter screen 2022. As the hanging plate 2015 rises, it lifts the dirt from the surface of the primary filter screen 2022, which is then flung out as the primary filter screen 2022 rotates, thus increasing the efficiency of the primary filter screen 2022. The surface of the filter screen 2022 is kept clean and free of dust, preventing dust and debris from adhering to the surface of the primary filter screen 2022 for extended periods. Furthermore, the descent of the pressure plate 2015 causes the dust and debris on the surface of the primary filter screen 2022 to be compressed and collected inside the storage cavity 2032. This ensures that excessive dust and debris do not come into contact with the primary filter screen 2022, preventing the surface from becoming entangled with fibers and ensuring the effective air filtration of the primary filter screen 2022.

[0089] The present invention can also be scaled up proportionally, and the equipment can be assembled and fixed by a frame to serve as a fixed air purifier and dust collector.

[0090] In summary, this invention increases the volume of the bottom cylinder 102 and the connecting cylinder 104 relative to the suction port 105, causing dust and debris to settle due to airflow pressure loss. The rotating cone-shaped column 2021 and the dispersing column 202 stabilize the airflow and guide it. The reciprocating rubbing of the inclined shovel ring 2011 and the processing ring 201 disturbs the disordered fiber bundle state in the dust and debris, thereby preventing the primary filter screen in the dust removal equipment from being blocked by fiber tips. Combined with the self-rotation of the primary filter screen 2022 and the reciprocating scraping of the hanging pressure plate 2015, the primary filter screen 2022 maintains airflow conduction while being easy to clean and self-cleaning. Example 2

[0091] like Figure 13 As shown, this embodiment provides a convenient cleaning method for using a combined dust collector, including the following steps:

[0092] Step 1, Dust Removal: Start the drive source 1022 to exhaust the air inside the extraction chamber 103, so that the dust and debris at the front end of the suction port 105 are sucked into the extraction chamber 103.

[0093] Step 2, Dispersion and Kneading: When dust and debris enter the extraction chamber 103, they are centrifugally dispersed by the rotating dispersion column 202 and cone-shaped column 2021 inside the extraction chamber 103, and are reciprocated and kneaded by the processing ring 201 and the inclined shovel ring 2011.

[0094] Step 3, Cleaning and Compression: When the drive source 1022 drives the primary filter screen 2022 to rotate, it will drive the hanging plate 2015 to reciprocate on the surface of the primary filter screen 2022, so that the dirt on the surface of the primary filter screen 2022 is cleaned in time, and the cleaned dirt is pressed down and compressed by the hanging plate 2015.

[0095] Step 4: Dust Collection: The dirt compressed by the pressure plate 2015 will fall into the storage chamber 2032 for storage.
