Description

Technical Field

[0001] This utility model relates to the field of dust absorption technology, and in particular to a high-efficiency dust absorption device. Background Technology

[0002] Currently, dust absorption devices, as important equipment for capturing and removing dust particles from the air, have been widely used in various fields such as industrial production, construction, and environmental protection. In existing technologies, common dust absorption devices mostly adopt a basic structure such as a shell, a collection container, and a top cover. They achieve cleaning of the inner wall of the collection container through components such as an internal mounting tube, a drive motor, a rotating shaft, a bracket, and a cleaning brush.

[0003] Chinese patent CN 222241846 U discloses a dust absorption device, including a shell, a collection bucket, and a top cover. A fixed mounting tube is installed inside the device, and a motor mounted on the top cover drives a rotating shaft to rotate. This rotates a cleaning brush fixed to a bracket on the outer wall of the shaft, which rubs and cleans the inner wall of the collection bucket. The suction force helps to remove dust adhering to the inner wall of the collection bucket, thus preventing dust accumulation to some extent. While the above technical solution improves dust adsorption and delays dust accumulation to a certain extent, it still has the following shortcomings in practical applications:

[0004] First, when the cleaning brush rubs against the inner wall of the collection bin, the dust scraped off is not completely expelled but remains at the bottom of the bin. With prolonged continuous use, this dust gradually accumulates, eventually clogging the gaps at the bottom of the bin, significantly reducing the filtration area and thus lowering the overall dust absorption efficiency. Once the dust accumulation in the collection bin reaches a certain level, effective adsorption ceases, forcing operators to disassemble the bin for manual cleaning. This, to some extent, limits the device's continuous operation capability.

[0005] Secondly, traditional dust collection bin cleaning methods require disassembling the bins and stopping the machine for cleaning. The equipment is stopped throughout the process, preventing dust collection. This frequent downtime not only increases maintenance time but can also cause production line stagnation, resulting in additional economic losses for the company. Furthermore, manual disassembly and cleaning are complex and labor-intensive, leading to relatively high equipment usage and maintenance costs.

[0006] Therefore, although the existing technology uses a motor to drive the shaft, bracket and cleaning brush to clean the dust inside the collection bucket, which has alleviated the dust adsorption problem to some extent, there are still problems such as dust accumulation leading to a reduction in the filtration area and the need to stop the machine during the cleaning process, which is inconvenient.

[0007] Therefore, this application is hereby submitted. Utility Model Content

It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0046] like Figures 1-8As shown in the figure, this application proposes a high-efficiency dust absorption device, including: a housing 1, with an air inlet on one side and an air outlet on the other side, a filter cartridge 18 inside, and a fan 16 at the air outlet; it also includes a cleaning component 51, disposed on the outside of the filter cartridge 18, and a first cleaning brush 52 is installed on the side of the cleaning component 51 close to the filter cartridge 18; a feeding mechanism, including: a feeding frame 2, connected below the dust discharge port 19 at the bottom of the housing 1, and the feeding frame 2 is welded to the bottom of the housing 1; and a feeding roller 21, rotatably connected to the feeding frame 2 via a rotating shaft 43. Between the two sides of the inner cavity of the feeding roller 21, the two ends of the feeding roller 21 move and abut against the two ends of the inner cavity of the feeding frame 2. A dust storage trough 22 is provided on the outer side of the feeding roller 21, and the surface height of the dust storage trough 22 is lower than the bottom height of the dust discharge port 19. A dust removal mechanism is used to clean the dust adsorbed on the feeding roller 21 and the dust storage trough 22. The dust removal mechanism includes: a dust removal frame 7, which is installed at the bottom of the feeding frame 2 and welded to the feeding frame 2. Both ends of the dust removal frame 7 are open in the vertical direction; a dust removal roller 72, which is rotated by a drive shaft. The dust removal roller 72 is movably connected within the dust removal frame 7, and its two ends are respectively movable against the two ends of the inner cavity of the dust removal frame 7. A second cleaning brush 73 is installed on the outer side of the dust removal roller 72, and the length of the second cleaning brush 73 is greater than the distance between the dust removal roller 72 and the dust storage tank 22. A drive mechanism is used to drive the rotation of the cleaning component 51, the feeding roller 21, and the dust removal mechanism. The drive mechanism includes: a mounting frame 3, which is installed at the end of the housing 1 away from the air outlet; and a drive motor 31, which is installed on the mounting frame 3. The drive of 31 is connected to the connecting shaft 5 via a coupling; the driving sprocket 4 is mounted on the outside of the connecting shaft 5; the driven sprocket 42 is mounted on one end of the rotating shaft 43 on the feed roller 21, and a chain 41 meshes between the driven sprocket 42 and the driving sprocket 4; the first gear 76 is mounted on the rotating shaft of the feed roller 21 at the end away from the driven sprocket 42; the second gear 77 is mounted on one end of the drive shaft on the dust removal roller 72, and the second gear 77 meshes with the first gear 76.

[0047] In this embodiment, during operation, the fan 16 is activated to create negative pressure inside the housing 1, thereby drawing dust into the housing 1 through the air inlet. The dust and air are then filtered through the filter cartridge 18. The filtered dust is located on the outside of the filter cartridge 18. When a large amount of dust adheres to the outside of the filter cartridge 18, affecting the dust filtration effect, the drive motor 31 is activated to drive the cleaning component 51 to rotate continuously on the outside of the filter cartridge 18. The first cleaning brush 52 forms a tight contact with the surface of the filter cartridge 18, peeling off the attached dust, which falls to the bottom of the inner cavity of the housing 1. At this time, the drive sprocket 4, driven sprocket 42, and chain 41 work together to drive the feeding roller 21 to rotate. When the dust storage trough 22 on the feeding roller 21 rotates and is positioned inside the dust discharge port 19, the cleaned dust falls into the dust storage trough 22. When the dust storage trough 22 containing dust rotates to face downwards, the dust in the dust storage trough 22 is poured out. Preferably, two dust storage troughs 22 are provided. The dust troughs 22 are symmetrically arranged along the center of the rotating shaft of the feeding roller 21. When one dust trough 22 is emptying dust, the other dust trough 22 rotates to the inside of the dust discharge port 19. Thus, the feeding roller 21 continues to rotate, which can automatically discharge the dust in the box 1. Since the feeding roller 21 blocks the feeding frame 2 during rotation, there is no need to stop the machine when cleaning and discharging dust, which further improves the efficiency of dust collection. When the feeding roller 21 rotates to discharge dust, the first gear 76 and the second gear 77 mesh, which drives the dust removal roller 72 to rotate. The second cleaning brush 73 can clean the dust in the dust trough 22, thereby realizing continuous automated operation of the entire dust absorption, filtration, cleaning and discharge process. Under the condition of multi-mechanism collaborative work, the suction area in the box is always large, avoiding dust adsorption in the dust trough 22 and affecting the dust discharge effect in the dust trough 22.

[0048] The high-efficiency dust absorption device described in this application utilizes the combined action of the cleaning component, the feeding mechanism, and the dust removal mechanism to achieve continuous dust intake, filtration, and automatic discharge under the negative pressure suction of the fan. This effectively avoids the defects of traditional equipment, such as reduced filter area of ​​the filter cartridge and equipment shutdown for cleaning due to long-term dust accumulation. This significantly improves dust absorption efficiency and the continuous operation capability of the equipment. At the same time, through continuous rotation and coordinated linkage between various mechanisms, the dust in the dust storage tank is effectively cleaned during the dumping process, reducing manual intervention and maintenance costs. Furthermore, the device features a simple and compact structural design and stable and reliable transmission linkage.

[0049] In some embodiments of this application, such as Figure 4As shown, the cleaning component 51 is U-shaped. Its inner first cleaning brush 52 movably abuts against the top, sides, and bottom of the filter cartridge 18. A connecting shaft 5 is installed on one side of the cleaning component 51. One end of the connecting shaft 5 rotatably passes through the housing 1 and is located on its outer side, connecting to the drive end of the drive mechanism. This arrangement, through the drive mechanism, drives the connecting shaft 5 installed on the outer side of the housing 1, causing the U-shaped cleaning component 51 to rotate continuously and stably. During rotation, the inner first cleaning brush 52 maintains full contact with the top, sides, and bottom of the filter cartridge 18, respectively. This allows the cleaning component 51 to evenly and comprehensively peel off and remove dust adhering to the surface of the filter cartridge as it rotates. Continuous friction removes dust promptly, preventing long-term dust accumulation and reducing the filter cartridge's filtration efficiency. Simultaneously, it achieves synchronous cleaning of all areas of the filter cartridge surface, ensuring the filter cartridge always maintains a large effective filtration area.

[0050] In some embodiments of this application, such as Figure 7 As shown, a baffle 6 is fixedly connected between the two sides of the inner cavity of the dust removal frame 7. The distance between the baffle 6 and the dust removal roller 72 is less than the length of the second cleaning brush 73. This arrangement, by setting a fixedly connected baffle 6 inside the dust removal frame 7, ensures that the distance between the baffle 6 and the dust removal roller 72 is always less than the length of the second cleaning brush 73. Therefore, when the dust removal roller 72 rotates and drives the second cleaning brush 73 to clean the dust in the dust storage tank 22, as the second cleaning brush 73 rotates past the baffle 6, the friction between the baffle 6 and the second cleaning brush 73 promptly removes the dust from the second cleaning brush 73, ensuring that the brush remains clean when in contact with the dust storage tank 22. This structure utilizes the interaction between the brush and the baffle 6 during continuous brush rotation to achieve automatic cleaning of dust on the brush, thus ensuring that the clean brush can efficiently remove residual dust in the dust storage tank 22 during dust discharge.

[0051] In some embodiments of this application, such as Figure 5 As shown, the housing 1 includes an air inlet pipe 11, which is connected to an air inlet on one side of the top of the housing 1. An air inlet hood 12 is installed on the top of the air inlet pipe 11. This effective connection between the air inlet pipe 11 and the air inlet at the top of the housing 1 allows external air to enter the housing 1 in a large and uniform manner under the guidance of the air inlet hood 12. This allows dust-laden air to quickly enter the area where the filter cartridge 18 is located under negative pressure, and high-speed airflow is achieved under the continuous drive of the fan 16, ensuring sufficient airflow before entering the filter cartridge. Simultaneously, the air inlet hood 12 improves the airflow state by expanding the air intake area, creating a more ideal velocity and pressure distribution when the air enters the housing. This avoids the problem of reduced dust capture efficiency due to insufficient local suction, thus improving dust collection efficiency.

[0052] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, a cover plate 13 is provided at one end of the air outlet. A second bolt 14 is provided on the cover plate 13, and the second bolt 14 passes through the cover plate 13 and is threaded to one end of the opening of the housing 1. A circular hole 15 is provided in the middle of the cover plate 13, and the fan 16 is installed in the circular hole 15, with the center of the circular hole 15 collinear with the rotation axis of the filter cartridge 18. A fixing ring 110 is installed on the outer side of the filter cartridge 18 near the cover plate 13, and four third bolts 17 pass through the fixing ring 110, all of which are threaded to one end of the cover plate 13. This setup involves installing a cover plate 13 at one end of the air outlet, and using four second bolts 14 on the cover plate 13 to securely connect the cover plate 13 to the opening end of the housing 1. A circular hole 15 is provided in the center of the cover plate 13 for installing a fan 16, ensuring that the center of the circular hole 15 is on the same horizontal line as the center of the filter cartridge 18. A retaining ring 110 is installed on the outer side of the filter cartridge 18 near the cover plate 13, and four third bolts 17 pass through the retaining ring 110. Through the cooperation of the second bolts 14 and the third bolts 17, the equipment can be disassembled first... Remove the cover plate 13, and then remove the filter cartridge 18 from the housing 1 using the retaining ring 110. Then, tighten the third bolt 17, which, together with the retaining ring 110, facilitates the removal of the filter cartridge 18 from the cover plate 13. This makes it easier to replace the damaged filter cartridge 18. Throughout the process, the connection between the fan, filter cartridge, and housing is ensured to be firm and the installation position is accurate, thereby ensuring continuous and stable operation of airflow and dust filtration. This makes the maintenance process simple and efficient, and facilitates timely replacement of damaged or heavily dust-accumulated filter cartridges 18 to maintain the efficient dust collection function of the device.

[0053] In some embodiments of this application, such as Figure 8 As shown, an elastic sealing gasket 23 is installed on the outer side of the feeding roller 21. The sealing gasket 23 increases the sealing performance between the feeding roller 21 and the inner wall of the feeding frame 2, thereby preventing gaps between the feeding roller 21 and the feeding frame 2 that would affect dust absorption.

[0054] In some embodiments of this application, such as Figure 7As shown, overlapping plates 74 are provided on both sides of the bottom of the dust collection frame 7. The two overlapping plates 74 are L-shaped, and a collection box 71 is provided between the two overlapping plates 74. Insertion blocks 75 are fixedly connected to both ends of the collection box 71. The two insertion blocks 75 are respectively inserted into the overlapping plates 74. By inserting the two insertion blocks 75 into the two overlapping plates 74, it is easy to connect the collection box 71 to the bottom of the dust collection frame 7, thus facilitating the collection of dust. During equipment operation, the dust collection mechanism guides the cleaned dust into the collection box 71. Due to the cooperation of the overlapping plates 74 and the insertion blocks 75, the dust collection... The collection box 71 remains stable even as dust accumulates. When the dust in the collection box 71 reaches a predetermined amount, an appropriate external force is applied to one side of the collection box 71, pulling it to one end. This causes the plug-in block 75 to detach from the overlapping plate 74, thus separating the collection box 71 from the dust storage frame 7. This allows operators to disassemble the collection box in a timely manner and clean or replace the dust inside. After the collection box is cleaned, the plug-in block 75 and the overlapping plate 74 are re-engaged to achieve stable installation of the collection box 71 and continuous operation of the system. This allows for efficient dust collection and timely cleaning without stopping the machine during continuous dust removal and discharge.

[0055] In summary, this utility model embodiment provides a high-efficiency dust absorption device. When cleaning dust on the outside of the filter cartridge 18, the drive motor 31 is started to drive the cleaning component 51 to rotate on the outside of the filter cartridge 18. The first cleaning brush 52 cleans and removes the dust adsorbed on the outside of the filter cartridge 18, which falls to the bottom of the inner cavity of the housing 1. At this time, the drive sprocket 4, the driven sprocket 42 and the chain 41 work together to drive the feeding roller 21 to rotate. When the dust storage tank 22 rotates and is placed inside the dust discharge port 19, the cleaned dust falls into the dust storage tank 22. When the dust storage tank 22 containing dust rotates to the point where the opening faces downward, the dust in the dust storage tank 22 is poured out. At this time, another dust storage tank 22 rotates to the inside of the dust discharge port 19, so that the feeding roller 21 can continuously rotate and automatically discharge the dust in the box 1. Since the feeding roller 21 blocks the feeding frame 2 during the rotation, there is no need to stop the machine when cleaning and discharging dust, which further improves the efficiency of dust collection. When the feeding roller 21 rotates to discharge dust, the first gear 76 and the second gear 77 mesh, thereby driving the dust removal roller 72 to rotate. The second cleaning brush 73 can clean the dust in the dust storage tank 22, preventing the dust from adsorbing in the dust storage tank 22 and affecting the dust discharge effect.

[0056] This application's high-efficiency dust absorption device automates the entire process of dust intake, filtration, cleaning, and emission through the coordinated linkage between various mechanisms. This significantly improves dust collection efficiency and avoids the shortcomings of traditional equipment, such as reduced filter area and downtime for cleaning due to long-term dust accumulation. It not only improves the continuous operation capability and operational stability of the equipment but also reduces maintenance costs and energy consumption, ensuring the continuous and efficient operation of the entire system.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
