A dust removal device designed based on self-cleaning function

Abstract

The present invention discloses a dust removal device designed based on a self-cleaning function, including a main unit, a first filter component and a filter cleaning assembly, wherein a filter element is arranged on the peripheral side of the first filter component, and a plurality of cleaning components are arranged on the inner wall of the filter cleaning assembly, which are used to clean the filter element during rotation. In the technical scheme of the present invention, when the device starts to inhale, since the dust-containing gas needs to enter the filter element from the gap to complete the filtering operation, the first filter component is set close to the base at this time, so that the airflow can be prevented from flowing out from the gap between the first filter component and the base, thereby ensuring the airtightness of the airflow channel inside the device. When the device stops inhaling and starts the self-cleaning function, since the filter cleaning assembly will inevitably drive the first filter component to rotate when rotating, a preset distance is set between the first filter component and the base at this time, so that relative friction between the two during the relative rotation process can be avoided, thereby ensuring the long service life of the first filter component.

It is currently widely used in industrial production sites and ordinary households.

[0003] Common dust removal equipment mainly includes an air suction device, a filter device and a support structure. The structural design method currently has the following technical defects and deficiencies:

[0004] ① The filter device in the dust removal equipment usually needs to be disassembled at regular intervals or when too much dust accumulates, and maintenance operations such as cleaning are performed. The operation is cumbersome and easy to damage the internal structure of the equipment;

[0005] ② If a structure specifically used for cleaning the filter device is designed inside the equipment, it is inevitable that the filter device will rotate when the cleaning structure is working, so a gap should be set between the filter device and the supporting structure to avoid structural wear; however, the filter device has extremely high requirements for the air tightness of the airflow during operation, so there should be no gap between the filter device and the supporting structure to avoid gas leakage; based on the above principles, the cleaning equipment in the prior art cannot take into account both the air tightness of the equipment and the structural service life of the filter device;

[0025] In summary, the dust removal device designed based on the self-cleaning function provided by the present invention has at least the following technical effects compared with the prior art:

[0026] 1) The dust removal equipment provided by the present invention is designed based on the self-cleaning function. The filter element of the first filter component is used to filter the dust-containing gas in the suction device, and the filter cleaning component is used to clean and maintain the first filter component. The specific principle is: the first filter component and the filter cleaning component can be rotatably installed at the bottom of the base, and the filter cleaning component is arranged around the outer peripheral side of the first filter component. The inner wall of the filter cleaning component is provided with a plurality of cleaning components in contact with the filter element, so that the particles such as moisture and dust adhering to the filter element can be removed during rotation, so as to avoid excessive deposition of liquid and dust on the filter element to affect its filtering effect, thereby realizing the filter cleaning function. This structural design method can realize the cleaning and maintenance operation of the first filter component without removing it from the equipment, and the structural design is simple and reasonable and easy to operate;

[0027] 2) The dust removal equipment provided by the present invention is designed based on the self-cleaning function. When the equipment starts to work and inhales air, the dust-containing gas sucked into the equipment enters the gap between the first filter component and the filter cleaning component from bottom to top under the suction force of the suction device, and then passes through the filtering action of the filter element arranged on the periphery of the first filter component. Liquid water, dust and other particulate matter adhere to and deposit on the filter element, and the filtered gas enters the accommodation space inside the first filter component, and then enters the main unit at the top thereof to complete further filtering operations. Among them, since the dust-containing gas needs to enter the filter element from the gap to complete the filtering operation, the first filter component is set close to the base at this time, which can prevent the airflow from flowing out from the gap between the first filter component and the base, thereby causing the unfiltered gas to directly enter the main unit, thereby ensuring the airtightness of the airflow channel inside the equipment;

[0028] 3) The dust removal device designed based on the self-cleaning function provided by the present invention, when the device stops inhaling air and starts the self-cleaning function, the filter cleaning component rotates to remove the particles such as moisture and dust adhering to the filter element by the cleaning components arranged on its inner wall, so as to avoid excessive deposition of liquid and dust on the filter element to affect its filtering effect, thereby realizing the filter cleaning function. Among them, since the cleaning components of the filter cleaning component need to contact the filter element (and the force between the two needs to be large enough) to realize the filter cleaning operation, the filter cleaning component will inevitably drive the first filter component to rotate when it rotates. At this time, a preset distance is set between the first filter component and the base, that is, the two are not set close together (or there is a gap between the two), so that the first filter component can be prevented from having relative friction with the base during rotation, thereby causing the first filter component or the base structure to wear, thereby ensuring a long service life of the first filter component.

[0043] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] See also Figure 1-Figure 3 , Figure 5 As shown, according to an embodiment of the present invention, a dust removal device designed based on a self-cleaning function includes a host 1, the host 1 includes a base 11 and a cover 12 arranged on the top of the base 11, and an installation space is formed between the base 11 and the cover 12. The installation space formed between the base 11 and the cover 12 is used to assemble a suction device, a motor, and a secondary filter component, etc. The external dust-containing gas enters the suction device and the secondary filter component in the installation space after being filtered by the first filter component 2, and is discharged from the installation space after completing the secondary filtration.

[0047] See also Figure 3 and Figure 5 As shown, the dust removal equipment designed based on the self-cleaning function also includes a first filter component 2 and a filter cleaning assembly 3. The first filter component 2 is rotatably installed at the bottom of the base 11. A filter element 21 is provided on the peripheral side of the first filter component 2. A accommodating space connected to the installation space is formed inside the first filter component 2. A gap 4 is formed between the inner wall of the filter cleaning assembly 3 and the first filter component 2, and the airflow in the gap 4 enters the accommodating space after passing through the filter element 21. Among them, the filter element 21 of the first filter component 2 is used to filter the dust-containing gas sucked into the dust removal device. The specific principle is as follows: when the dust removal device starts to work and inhales air, the dust-containing gas sucked into the dust removal device enters the gap 4 between the first filter component 2 and the filter cleaning component 3 from bottom to top under the suction force of the suction device, and then after filtering by the filter element 21 set on the side of the first filter component 2, liquid water, dust and other particles adhere to and deposit on the filter element 21, and the filtered gas enters the accommodation space inside the first filter component 21, and then enters the interior of the host 1 (that is, the installation space) through the opening at the top of the first filter component 2 to complete further filtering operations. Preferably, the first filter component 2 can be preferably a HEPA component.

[0048] See also Figure 3 , Figure 4 and Figure 5As shown, in the technical solution of this embodiment, the filtering and cleaning component 3 is rotatably mounted on the bottom of the base 11, and the filtering and cleaning component 3 is arranged around the outer peripheral side of the first filtering component 2, and the inner wall of the filtering and cleaning component 3 is provided with a plurality of cleaning components 31, and the end of the cleaning component 31 is in contact with the filter element 21, which is used to clean the filter element 21 during rotation. Among them, the filtering and cleaning component 3 is used to realize the cleaning and maintenance function of the first filtering component 2, and the specific principle is as follows: since the first filtering component 2 and the filtering and cleaning component 3 can be rotatably mounted on the bottom of the base 11, and the filtering and cleaning component 3 is arranged around the outer peripheral side of the first filtering component 2, and the inner wall of the filtering and cleaning component 3 is provided with a plurality of cleaning components 31 in contact with the filter element 21, when the filtering and cleaning component 3 rotates, the synchronously rotating cleaning components 31 can remove the particles such as moisture and dust adhering to the filter element 21, so as to avoid excessive deposition of liquid and dust on the filter element 21 and affect its filtering effect, thereby realizing the filtering and cleaning function. Through the above structural design, the first filter component 2 can be cleaned and maintained without removing it from the dust removal device, and the structural design is simple and reasonable and convenient for users to operate. More specifically, the cleaning component 31 can be a brush structure.

[0049] Furthermore, in the technical solution of this embodiment, the first filter component 2 is arranged close to the base 11 when the airflow passes through the gap 4. Specifically, when the device starts to work and inhales air, since the dust-containing gas needs to enter the filter element 21 from the gap 4 between the first filter component 2 and the filter cleaning component 3 to complete the filtering operation, the first filter component 2 is arranged close to the base 11 at this time, so as to avoid the airflow from the gap between the first filter component 2 and the base 11, thereby avoiding the phenomenon that the unfiltered gas directly enters the inside of the main unit 1, and ensuring the airtightness of the airflow channel inside the dust removal device.

[0050] In addition, in the technical solution of this embodiment, a preset distance is set between the first filter component 2 and the base 11 when the filter cleaning component 3 rotates. Specifically, when the device stops inhaling and starts the self-cleaning function, the filter cleaning component 3 rotates so that the cleaning component 31 arranged on its inner wall removes particles such as moisture and dust adhering to the filter element 21. Among them, since the cleaning component 31 of the filter cleaning component 3 needs to contact the filter element 21 (and the force between the cleaning component 31 and the filter element 21 needs to be large enough) to achieve the filtering and cleaning operation, the filter cleaning component 3 will inevitably drive the first filter component 2 to rotate when it rotates. At this time, a preset distance is set between the first filter component 2 and the base 11, that is, the first filter component 2 and the base 11 are not set tightly (or there is a gap between the two), which can avoid the relative friction between the first filter component 2 and the base 11 during the rotation process, thereby avoiding the phenomenon of structural wear of the first filter component 3 or the base 11, and improving the service life of the first filter component 2.

[0051] See also Figure 6 As shown, in one embodiment of the present invention, the dust removal device designed based on the self-cleaning function further includes a first connecting member 5, the filter cleaning assembly 3 includes a connecting portion 32, a first slide groove 33 is provided on the top of the connecting portion 32, and the first connecting member 5 passes through the first slide groove 33 and the base 11 in the vertical direction, so that the filter cleaning assembly 3 is rotatably installed at the bottom of the base 11. In the technical solution of this embodiment, the first connecting member 5 and the base 11 are in a fixed connection relationship, and a gap is provided between the first connecting member 5 and the first slide groove 33. When a rotational force is applied to the filter cleaning assembly 3, the first connecting member 5 can slide in the first slide groove 33, thereby realizing the rotational movement of the filter cleaning assembly 3.

[0052] See also Figure 6 As shown, in the preferred solution of this embodiment, the upper and lower ends of the connecting portion 5 are respectively fixed with a first stopper 51 and a second stopper 52, the first stopper 51 abuts against the base 11, and the second stopper 52 abuts against the connecting portion 32, so as to support the filter cleaning assembly 3. Specifically, the first stopper 51 abuts against the base 11, and the second stopper 52 abuts against the connecting portion 32, so as to limit and support the filter cleaning assembly 3 at the upper and lower ends in the vertical direction, and install the filter cleaning assembly 3 at the bottom of the base 11. More specifically, in order to realize the rotation movement of the filter cleaning assembly 3, a small gap is provided between the filter cleaning assembly 3 and the base 11 to avoid friction when the two rotate relative to each other, thereby causing structural damage to the filter cleaning assembly 3 or the base 11.

[0053] See also Figure 7As shown, in another embodiment of the present invention, the dust removal device designed based on the self-cleaning function also includes a second connecting member, a second slide groove 22 is provided on the top of the first filter component 2, and the second connecting member passes through the second slide groove 22 and the base 11 in the vertical direction. Among them, the bottom of the second connecting member is used to support the first filter component 2, and the second connecting member can be lifted and lowered relative to the base 11, thereby driving the first filter component 2 to lift and lower. In the technical solution of this embodiment, a limited position structure is formed at the bottom of the second connecting member, so as to support the first filter component 2; a gap is provided between the second connecting member and the second slide groove 22, and when a rotational force is applied to the first filter component 2, the second connecting member can slide in the second slide groove 22, thereby realizing the rotational movement of the first filter component 2.

[0054] See also Figure 7 As shown, in the preferred embodiment of the embodiment, the dust removal device based on the self-cleaning function design also includes a first drive motor 63 and a first gear 64, the second connecting member includes a screw portion 61 and a worm portion 62, the screw portion 61 is meshed and connected with the base 11, the first gear 64 is meshed with the worm portion 62, and the first drive motor 63 drives the first gear 64 to rotate, thereby driving the second connecting member to move up and down. Specifically, the outer surface of the screw portion 61 is provided with an external thread, and the inner surface of the base 11 is provided with an internal thread, and the two are meshed and connected, so that the lifting and lowering movement of the second connecting member is realized when the screw portion 61 rotates. In addition, the first gear 64 is meshed with the worm portion 62, so when the first drive motor 63 starts working, the first gear 64 is driven to rotate, thereby driving the worm portion 62 to rotate, that is, driving the screw portion 61 to rotate, and finally realizing the lifting and lowering movement of the second connecting member, so that the first filter component 2 can switch between up and down movement according to the suction working state and the self-cleaning state of the dust removal device.

[0055] See also Figure 6 and Fig. 9 As shown, in another embodiment of the present invention, the dust removal device designed based on the self-cleaning function also includes a second gear 7 arranged at the bottom of the base 11, and the outer peripheral side of the filter cleaning component 3 is provided with a first external tooth 34, and the second gear 7 is meshed and connected with the first external tooth 34, so that the filter cleaning component 3 is driven to rotate when the second gear 7 rotates. In the technical solution of this embodiment, in the two components of the second gear 7 and the filter cleaning component 3, the second gear 7 is used as a driving wheel, and the filter cleaning component 3 is used as a driven wheel. The second gear 7 can drive the filter cleaning component 3 to rotate through gear meshing, and then drive the cleaning component 31 to rotate synchronously, remove the particles such as moisture and dust adhering to the filter element 21, and avoid excessive deposition of liquid and dust on the filter element 21 to affect its filtering effect, thereby realizing the filtering and cleaning function.

[0056] See also Figure 8 and Fig. 9 As shown, in an optional technical solution of this embodiment, the dust removal device designed based on the self-cleaning function also includes a second drive motor 71, which is arranged at the top of the base 11, and its output shaft is fixedly connected to the second gear 7, and is used to drive the second gear 7 to rotate. In this optional solution, the second drive motor 71 drives the second gear 7 to rotate to drive the filter cleaning component 3 to achieve the filter cleaning function, and the second drive motor 71 is arranged at the top of the base 11, which does not occupy the installation space of the dust removal device, and the space utilization rate is high.

[0057] See also Figure 10-12 As shown, in another optional scheme of this embodiment, the dust removal device designed based on the self-cleaning function also includes a third gear 8, a worm 81 and a handle 82, all of which are arranged on the top of the base 11. The third gear 8 is fixedly connected to the second gear 7 through a transmission shaft, the worm 81 is meshed with the third gear 8, and the handle 82 is fixedly connected to the worm 81. By rotating the handle 82, the worm 81 can be driven to rotate, thereby driving the second gear 7 to rotate. Specifically, in this optional technical solution, the third gear 8 drives the second gear 7 to rotate to drive the filter cleaning component 3 to achieve the filter cleaning function, and the third gear 8 is driven by the worm 81 and the handle 82 to rotate. The specific principle is as follows: when the handle 82 is rotated by hand, the worm 81 can be driven to rotate synchronously. Since the worm 81 is meshed with the third gear 8, the third gear 8 is driven to rotate at the same time, thereby driving the second gear 7 to rotate, and finally driving the filter cleaning component 3 to rotate to achieve the filter cleaning function.

[0058] See also Figure 3 , Figure 8 and Fig.10 As shown, in another embodiment of the present invention, the installation space is provided with an air suction device 9, the air inlet 91 of the air suction device 9 is connected to the accommodation space, the air outlet duct 92 of the air suction device 9 is fixedly provided with a second filter component 93, and the end of the air outlet duct 92 is provided with an air outlet 13. Specifically, the air suction device 9 is used as the air suction power component of the dust removal equipment. When the air suction device 9 starts working, the external dust-containing gas enters the dust removal equipment under the suction force to complete the filtering operation. More specifically, after the dust-containing gas passes through the filtering action of the filter element 21 of the first filter component 2, it passes through the accommodation space of the first filter component 2, the air inlet 91 of the air suction device 9, the interior of the air suction device 9, the air outlet duct 92 of the air suction device 9 and the air outlet 13 in sequence, and is finally discharged from the air outlet 13. Among them, the second filter component 93 provided in the air outlet duct 92 can preferably be a HEPA component, which is used to perform a secondary filtering action on the passing gas to further enhance the filtering and dust removal effect.

[0059] join Figure 1 As shown, in another embodiment of the present invention, the dust removal device designed based on the self-cleaning function also includes a water tank 10, which is arranged at the bottom of the main unit 1, and the box body of the water tank 10 is provided with an air inlet 101, and a water filter assembly is arranged inside the box body, and the gas filtered by the water filter assembly flows upward into the gap 4. In the technical scheme of this embodiment, a water storage chamber and a water filter assembly are arranged inside the box body of the water tank 10, and the water filter assembly is at least partially arranged in the water storage chamber. When the gas entering the box body from the air inlet 101 passes through the water storage chamber, the dust and other particles in the gas are moistened, dissolved, and precipitated in the water in the water storage chamber, thereby achieving a water filtering effect. The gas after water filtration flows upward into the gap 4 between the first filter component 2 and the filter cleaning assembly 3 to perform the filtering operation of the filter element 21 in the next step.

[0060] To sum up, the filter element 21 of the first filter component 2 provided by the present invention is used to filter the dust-containing gas in the suction equipment, and the filter cleaning component 3 is used to clean and maintain the first filter component 2. The specific principle is: the first filter component 2 and the filter cleaning component 3 can be rotatably installed on the bottom of the base 11, and the filter cleaning component 3 is arranged around the outer peripheral side of the first filter component 2. The inner wall of the filter cleaning component 3 is provided with a plurality of cleaning components 31 in contact with the filter element 21. Therefore, particles such as moisture and dust adhering to the filter element 21 can be removed during rotation to avoid excessive deposition of liquid and dust on the filter element 21 and affect its filtering effect, thereby realizing the filtering and cleaning function. This structural design method does not need to remove the first filter component 2 from the equipment to realize its cleaning and maintenance operations. The structural design is simple and reasonable, and the operation is easy. Furthermore, when the dust removal device of the present invention starts to work and inhale, the dust-containing gas sucked into the equipment enters the gap 4 between the first filter component 2 and the filter cleaning component 3 from bottom to top under the suction force of the suction device 9, and then after filtering by the filter element 21 arranged on the side of the first filter component 2, liquid water, dust and other particulates adhere to and deposit on the filter element 21, and the filtered gas enters the accommodation space inside the first filter component 2, and then enters the installation space inside the main unit 1 at the top thereof to complete further filtering operations. Among them, since the dust-containing gas needs to enter the filter element 21 from the gap 4 to complete the filtering operation, the first filter component 2 is set close to the base 11 at this time, which can avoid the airflow from the gap between the first filter component 2 and the base 11, thereby causing the unfiltered gas to directly enter the main unit 1, thereby ensuring the airtightness of the airflow channel inside the device. In addition, when the dust removal device of the present invention stops inhaling air and starts the self-cleaning function, the filter cleaning component 3 rotates so that the cleaning component 31 set on its inner wall removes the particles such as moisture and dust adhering to the filter element 21, thereby preventing excessive deposition of liquid and dust on the filter element 21 to affect its filtering effect, thereby realizing the filter cleaning function. Among them, since the cleaning component 31 of the filter cleaning component 3 needs to contact the filter element 21 (and the force between the two needs to be large enough) to realize the filter cleaning operation, the filter cleaning component 3 will inevitably drive the first filter component 2 to rotate when rotating. At this time, a preset distance is set between the first filter component 2 and the base 11, that is, the two are not set close to each other (or there is a gap between the two), so that the first filter component 2 can be prevented from having relative friction with the base 11 during the rotation process, thereby causing the first filter component 2 or the base 11 to wear and tear, thereby ensuring a long service life of the first filter component 2.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
