Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a dust removal and adsorption device for baghouse dust collectors. Background Technology

[0002] The working principle of a baghouse dust collector is to filter dust-laden gas using the filtration effect of fibrous fabric. When the dust-laden gas enters the baghouse dust collector, large, heavy dust particles settle down due to gravity and fall into the ash hopper; while the gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. The accumulated dust on the filter bags can be removed using reverse rinsing or pulse jet cleaning. It boasts high dust removal efficiency: baghouse dust collectors typically achieve a dust removal efficiency of over 99%, with the dust concentration in the outlet gas within tens of mg / m³. It also has high classification efficiency for submicron-sized fine dust particles. Furthermore, it features a simple structure. Easy to maintain and operate, relatively low cost: Under the premise of ensuring the same high dust removal efficiency, the cost of bag dust collectors is lower than that of electrostatic precipitators. High temperature resistance: When using high temperature resistant filter materials such as glass fiber, polytetrafluoroethylene, and P84, bag dust collectors can operate at temperatures above 200 degrees Celsius. Strong applicability: Bag dust collectors are not sensitive to the characteristics of dust and are not affected by dust and resistance. Bag dust collectors are widely used in environmental protection equipment in industrial projects such as mining, cement, building materials, and grain. At the same time, bag dust collectors are also used in homes, offices, vehicles, and public places, such as for vacuuming floors, carpets, and furniture, which can maintain environmental cleanliness and hygiene.

[0003] The existing technical solutions mentioned above have the following drawbacks: Existing baghouse dust collectors capture and filter smoke or dust particles in the air through filter bags. Over time, a layer of dust will gradually accumulate on the surface of the filter bags. As time goes by, the dust accumulates more and more, and the air permeability of the filter bags will gradually decrease. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a dust collection and adsorption device for baghouse dust collectors, which has the advantage of being easy to clean. This solves the problem that in existing baghouse dust collectors, which capture and filter smoke or dust particles in the air through filter bags, a layer of dust gradually accumulates on the surface of the filter bags over time, and as the dust accumulates, the air permeability of the filter bags gradually decreases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collection and adsorption device for a bag filter, comprising a housing, an impeller connected to the surface of the housing, a motor fixedly connected to the right side of the impeller, a filter plate installed on the top of the inner wall of the housing, filter bags connected to both sides of the bottom of the filter plate, a cleaning structure provided on the surface of the filter bags, the cleaning structure comprising a cleaning block located on the surface of the filter bags, a connecting plate fixedly connected to the bottom of the cleaning block, a vertical rod fixedly connected to the bottom of the connecting plate, a bearing fixedly connected to the surface of the vertical rod, the bottom of the bearing fixedly connected to the bottom of the inner wall of the housing, an air outlet opened on the top of the housing, and a drive structure provided on the front of the housing.

[0006] In a preferred embodiment of this invention, the driving structure includes a first gear located on the surface of a vertical rod. A second gear meshes with the front end of the bottom of the first gear. A horizontal rod is fixedly connected to the front of the second gear. A third gear is fixedly connected to the front of the horizontal rod. A fourth gear meshes with the inner side of the third gear. A connecting rod is fixedly connected to the inner side of the fourth gear. A first pulley is fixedly connected to the surface of the connecting rod. A second pulley is provided on the surface of the first pulley. The second pulley and the first pulley are connected by a belt drive. The interior of the second pulley is fixedly connected to the output end of the motor.

[0007] As a preferred embodiment of this invention, a first sleeve is fitted onto the surface of the crossbar, and the bottom of the first sleeve is fixedly connected to the bottom of the inner wall of the box.

[0008] As a preferred embodiment of this invention, a first sleeve is fitted onto the surface of the crossbar, and the bottom of the first sleeve is fixedly connected to the bottom of the inner wall of the box.

[0009] As a preferred embodiment of this utility model, the front of the box body is provided with a through hole, and a hollow block is fixedly connected inside the through hole.

[0010] As a preferred embodiment of this invention, a fixing block is fixedly connected to the bottom of the motor, and the front of the fixing block is fixedly connected to the back of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, after the motor is started, drives the impeller to rotate at its output end, thereby generating suction to draw surrounding dust or smoke into the dust collector housing. This dust or smoke is then filtered through filter bags, which effectively block dust particles. The filtered air then passes through the filter plate and enters the outlet to exit the housing, ensuring that the emitted gas meets cleanliness standards. Simultaneously, the motor's rotation also drives a series of gears and connecting rods to rotate via a belt drive system. Specifically, the first pulley and the second pulley are connected by a belt. The motor drives the first pulley to rotate, which in turn drives the second pulley and subsequent connecting rods, gears, and other components to rotate. The series of rotational movements ultimately translates into the rotation of the connecting disc and the vertical rod, which are mounted in the appropriate positions via bearings. The rotation of the connecting disc drives the cleaning block to clean the surface of the filter bag. As the cleaning block rotates, it effectively removes the dust adsorbed on the filter bag, preventing dust accumulation from affecting the filtration efficiency of the filter bag. This baghouse dust collector uses a dust adsorption device that has the advantage of cleaning, improving the stability of the housing. At the same time, it avoids the problem of existing baghouse dust collectors capturing and filtering smoke or dust particles in the air through filter bags. Over time, a layer of dust will gradually accumulate on the surface of the filter bag. As the dust accumulates, the air permeability of the filter bag will gradually decrease.

[0013] 2. This utility model, through the setting of the driving structure, can drive the cleaning block to clean the filter bag, preventing the filter bag surface from adsorbing a large amount of dust, thereby affecting the filtration effect of the filter bag. Attached Figure Description

[0021] refer to Figure 3 The drive structure 8 includes a first gear 81 located on the surface of the vertical rod 63. A second gear 82 meshes with the front end of the bottom of the first gear 81. A horizontal rod 83 is fixedly connected to the front of the second gear 82. A third gear 84 is fixedly connected to the front of the horizontal rod 83. A fourth gear 85 meshes with the inner side of the third gear 84. A connecting rod 86 is fixedly connected to the inner side of the fourth gear 85. A first pulley 87 is fixedly connected to the surface of the connecting rod 86. A second pulley 88 is provided on the surface of the first pulley 87. The second pulley 88 and the first pulley 87 are connected by a belt drive. The interior of the second pulley 88 is fixedly connected to the output end of the motor 3.

[0022] As a technical optimization of this utility model, by setting the driving structure 8, the cleaning block 61 can be driven by the driving structure 8 to clean the filter bag 5, preventing a large amount of dust from adsorbing on the surface of the filter bag 5, thereby affecting the filtration effect of the filter bag 5.

[0023] refer to Figure 1 The surface of the crossbar 83 is fitted with a first sleeve 9, and the bottom of the first sleeve 9 is fixedly connected to the bottom of the inner wall of the box 1.

[0024] As a technical optimization of this utility model, the first sleeve 9 can limit the horizontal bar 83 and prevent it from shaking when rotating.

[0025] refer to Figure 1The surface of the crossbar 83 is fitted with a first sleeve 9, and the bottom of the first sleeve 9 is fixedly connected to the bottom of the inner wall of the box 1.

[0026] As a technical optimization of this utility model, by setting the second sleeve 10, the connecting rod 86 can be limited by the second sleeve 10 to prevent the connecting rod 86 from shaking when rotating.

[0027] refer to Figure 4 The front of the box 1 has a through hole 11, and a hollow block 12 is fixedly connected inside the through hole 11.

[0028] As a technical optimization of this utility model, the through hole 11 enables transmission between the first pulley 87 and the second pulley 88, and the hollow block 12 protects the belt.

[0031] The working principle and usage process of this utility model are as follows: When in use, after the motor 3 starts, its output end drives the impeller 2 to rotate, thereby generating suction to draw the surrounding dust or smoke into the dust collector housing 1. This dust or smoke is then filtered through the filter bag 5, which can effectively block dust particles. The filtered air enters the air outlet 7 through the filter plate 4 and is discharged from the housing 1, ensuring that the discharged gas meets the cleanliness standard. At the same time, the rotation of the motor 3 also drives the rotation of a series of gears and connecting rods 86 through the belt drive system. Specifically, the first pulley 87 and the second pulley 88 are connected by a belt. The motor 3 drives the first pulley 87 to rotate, which in turn drives the second pulley 88 and subsequent connecting rods 86, gears and other components to rotate. This series of rotational actions is finally converted into the rotation of the connecting plate 62 and the vertical rod 63. They are installed in the appropriate position through the bearing 64. The rotation of the connecting plate 62 drives the cleaning block 61 to clean the surface of the filter bag 5. As the cleaning block 61 rotates, it can effectively remove the dust adsorbed on the filter bag 5 and prevent the dust accumulation from affecting the filtration efficiency of the filter bag 5.

[0032] In summary, this baghouse dust collector uses a dust collection and adsorption device. Through the coordinated use of the housing 1, impeller 2, motor 3, filter plate 4, filter bag 5, cleaning structure 6, cleaning block 61, connecting plate 62, vertical rod 63, bearing 64, and air outlet 7, it solves the problem that existing baghouse dust collectors, which capture and filter smoke or dust particles in the air through filter bags, will gradually accumulate a layer of dust on the surface of the filter bags over time. As the dust accumulates, the air permeability of the filter bags will gradually decrease.
