Description

Technical Field

[0001] This utility model relates to the fields of environmental engineering and industrial air purification, and in particular to a high-efficiency dust removal device for sandblasting exhaust gas. Background Technology

[0002] High-efficiency dust removal equipment for sandblasting exhaust gas is an environmentally friendly device used to treat the exhaust gas and dust generated during the sandblasting process. Sandblasting is a surface treatment process that uses high-speed jets of abrasive particles or other materials onto the surface of a workpiece to achieve cleaning, rust removal, and surface roughening. However, this process generates a large amount of dust and fine particulate matter, which not only pollutes the environment but may also harm the health of operators.

[0003] Currently, most dust removal equipment on the market faces a common problem after long-term operation: as the usage time increases, a large amount of dust gradually accumulates on the surface of the filter bags. This situation leads to a continuous increase in the resistance of airflow when passing through the filter bags, which in turn significantly reduces the overall working efficiency of the dust removal equipment. Specifically, this manifests as slower filtration speed, increased energy consumption, and weakened purification effect. Long-term dust accumulation not only increases the burden on the equipment but may also cause premature wear of the filter bag material, affecting its service life. Furthermore, frequent manual cleaning or replacement of filter bags significantly increases maintenance costs and downtime.

[0004] To address the aforementioned issues, a high-efficiency dust removal device for sandblasting exhaust gas needs to be designed. Utility Model Content

[0005] To overcome the drawback that as the usage time increases, a large amount of dust gradually accumulates on the surface of the filter bag, which leads to a continuous increase in the resistance of airflow passing through the filter bag and thus a significant decrease in the overall working efficiency of the dust removal equipment, this utility model provides a high-efficiency dust removal device for sandblasting exhaust gas.

[0006] The technical solution of this utility model is: a high-efficiency dust removal device for sandblasting exhaust gas, comprising a first outer shell, an air inlet, an air outlet, a connecting plate, filter bags, a fixing plate, elastic elements, a dual-shaft motor, support blocks, rotating shafts, and centrifugal blocks. The air inlet is connected to the lower left side of the first outer shell, and the air outlet is connected to the upper right side of the first outer shell. The connecting plate is slidably connected inside the first outer shell, and multiple filter bags are evenly spaced on the connecting plate. The fixing plate is connected inside the first outer shell, and elastic elements are connected between the fixing plate and the connecting plate. The dual-shaft motor is installed on the upper side of the connecting plate, and rotating shafts are connected to the output shafts at both ends of the dual-shaft motor. Support blocks are symmetrically connected to the left and right sides of the connecting plate, and the two rotating shafts are rotatably engaged with the corresponding support blocks. Centrifugal blocks are connected to the two rotating shafts.

[0007] In one embodiment, it further includes a support frame, a second outer shell, a first connecting pipe, a second connecting pipe, and inclined plates. The support frame is connected to the left side of the first outer shell, and the second outer shell is placed inside the support frame. The first connecting pipe is connected to the left side of the second outer shell, and the second connecting pipe is connected to the right side of the second outer shell. Multiple inclined plates are placed alternately inside the second outer shell.

[0008] In one embodiment, handles are also included, with each ramp equipped with a handle.

[0009] In one embodiment, a cooler is also included, which is installed on the left side of the first connecting pipe.

[0010] In one embodiment, the size of the fixing plate is designed to fit the interior of the first housing.

[0011] In one embodiment, a sealing ring is also included, with a sealing ring connected to each ramp.

[0012] The beneficial effects of this utility model are as follows: By setting up a dual-axis motor, rotating shafts and centrifugal blocks, the dual-axis motor drives the rotating shafts at both ends to rotate, and the centrifugal blocks on the two rotating shafts rotate accordingly and generate centrifugal force. This centrifugal force is transmitted to the connecting plate through a specific mechanical structure, causing the connecting plate to drive multiple filter bags to move up and down reciprocally. During this process, the dust attached to the surface of multiple filter bags is dislodged due to the shaking, effectively preventing multiple filter bags from clogging and ensuring that multiple filter bags always maintain high-efficiency filtration performance. At the same time, the compression and reset actions of multiple elastic elements further enhance the dust removal effect. Attached Figure Description

Detailed Implementation

[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] Example: A high-efficiency dust removal device for sandblasting exhaust gas, such as Figures 1-5 As shown, it includes a first outer shell 1, an air inlet 2, an air outlet 3, a connecting plate 4, a filter bag 5, a fixing plate 6, an elastic element 7, a dual-shaft motor 8, a support block 9, a rotating shaft 10, a centrifugal block 11, a support frame 12, a second outer shell 13, a first connecting pipe 14, a second connecting pipe 15, an inclined plate 16, a handle 17, a sealing ring 18, and a cooler 19. The air inlet 2 is connected to the lower left side of the first outer shell 1, and the air outlet 3 is connected to the upper right side of the first outer shell 1. The connecting plate 4 is slidably connected inside the first outer shell 1, and the connecting plate 4 is evenly distributed on the surface. Multiple filter bags 5 are connected at intervals. The filter bags 5 are used to filter particulate matter in the exhaust gas to ensure that the exhaust gas meets environmental protection standards. A fixing plate 6 is connected inside the first outer shell 1. The size of the fixing plate 6 is adapted to the interior of the first outer shell 1. Elastic elements 7 are connected between the fixing plate 6 and the connecting plate 4. A dual-shaft motor 8 is installed on the upper side of the connecting plate 4. Rotating shafts 10 are connected to the output shafts at both ends of the dual-shaft motor 8. Support blocks 9 are symmetrically connected to the left and right sides of the connecting plate 4. The two rotating shafts 10 are rotatably engaged with the corresponding support blocks 9. Centrifugal blocks 11 are connected to the two rotating shafts 10. The centrifugal blocks 11 can rotate with the rotating shafts 10 and generate centrifugal force. This force is transmitted to the connecting plate 4 through a specific mechanism, causing the filter bags 5 to shake. A support frame 12 is connected to the left side of the first outer shell 1. A second outer shell 13 is placed inside the support frame 12. The second outer shell 13 is used for the preliminary treatment of exhaust gas to help larger particles settle and pre-separate. A first connecting pipe 14 is connected to the left side of the second outer shell 13. A second connecting pipe 15 is connected to the right side of the second outer shell 13. The interior of the second outer shell 13 is staggered. Multiple inclined plates 16 are placed, which can form a complex path to force the exhaust gas to flow and promote the settling of particulate matter. Each inclined plate 16 is equipped with a handle 17, which makes it easy to disassemble and clean the dust on the inclined plate 16. Each inclined plate 16 is connected with a sealing ring 18, which can ensure a tight connection between the inclined plate 16 and the second housing 13 to prevent the leakage of untreated exhaust gas. A cooler 19 is installed on the left side of the first connecting pipe 14. The cooler 19 is used to initially cool the high-temperature sandblasting exhaust gas.

[0021] When this device is needed to treat sandblasting exhaust gas, firstly, the cooler 19 is started to operate. The high-temperature sandblasting exhaust gas enters the cooler 19 and undergoes initial cooling. After cooling, the exhaust gas then enters the second housing through the first connecting pipe 14. The second housing contains multiple staggered inclined plates 16, which force the exhaust gas to flow along a complex path formed by the inclined plates 16, facilitating the natural settling and pre-separation of larger particles. Next, the pre-treated exhaust gas passes through the second connecting pipe 15 and is guided to the inlet 2, then enters the first housing. Here, the exhaust gas passes through multiple filter bags 5, which effectively trap fine particles in the exhaust gas. The system achieves highly efficient air purification. Simultaneously, the dual-axis motor 8 starts, and the output shafts at both ends of the dual-axis motor 8 drive two rotating shafts 10 to rotate. The two rotating shafts 10 drive the centrifugal blocks 11 on them to rotate. As the two centrifugal blocks 11 rotate, they generate centrifugal force, which is transmitted to the connecting plate 4 through a specific mechanism. This causes the connecting plate 4 to move multiple filter bags 5 up and down. Multiple elastic elements 7 are repeatedly compressed and reset, which helps to shake off the dust accumulated on the surface of multiple filter bags 5 and maintain the high-efficiency filtration performance of multiple filter bags 5. Finally, the gas purified by multiple filter bags 5 is discharged through the air outlet 3, meeting environmental emission standards. The above process will continue to run until the sandblasting operation is completed, at which point the dual-axis motor 8 and the cooler 19 are turned off, ending the dust removal operation.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
