Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and more specifically, to a pulse-jet bag filter dust collector. Background Technology

[0002] Pulse jet baghouse dust collectors are a type of high-efficiency dry dust collection equipment, widely used in industrial dust control.

[0003] The main principle of a baghouse dust collector is that dust-laden gas enters the dust collector through the inlet. As it passes through the outer surface of the filter bag, the dust is trapped on the outside of the filter bag, and the purified gas is discharged from the inside of the filter bag and flows out of the dust collector through the outlet, thus achieving the effect of air dust removal. As dust accumulates, the resistance of the filter bag increases. At this time, the dust is periodically cleaned by the pulse jet cleaning system. Compressed air is injected into the inside of the filter bag through the pulse valve, generating violent expansion and vibration, which causes the dust attached to the surface of the filter bag to fall off and fall into the ash hopper below the filter bag.

[0004] In some baghouse dust collectors, the filter bags are relatively long, with the lower end extending close to the dust hopper. This design ensures efficient entry of dust-laden gas into the filter bags. The air inlet is usually located on the side wall of the dust hopper. However, the primary function of the dust hopper is to store dust. When there is a relatively large amount of dust in the dust hopper, the dust-laden gas entering through the air inlet can easily stir up the dust in the dust hopper, thereby increasing the filtration pressure on the filter bags and thus increasing the frequency of filter bag cleaning.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pulse-type bag filter dust collector.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pulse-jet bag filter, comprising a dust collector body and a dust hopper, wherein a plurality of filter bags are provided inside the dust collector body, and a blower pipe is also provided inside the dust collector body above the filter bags and corresponding to each filter bag. An air outlet and an air inlet are respectively provided on the side walls of the dust collector body and the dust hopper. The dust collector body and the dust hopper are characterized in that: a dust storage box is fixedly connected to the bottom of the dust hopper, and a connecting channel is provided between the dust storage box and the dust hopper. A conveying blade is rotatably connected in the connecting channel, and the conveying blade can carry the dust in the dust hopper into the dust storage box. A guide plate is also provided on the inner wall of the dust hopper, and the guide plate is located below the air inlet and is inclined upward.

[0008] The present invention is further configured such that: the connecting channel includes an arc segment, the arc segment includes a front wall, a rear wall and two oppositely arranged arc walls, the conveying blade includes a rotating shaft and a plurality of blades fixedly connected to the outer peripheral wall of the rotating shaft, the two ends of the blades respectively abut against the front wall and the rear wall, and in the arc segment, at least two blades abut against the two arc walls respectively.

[0009] The present invention is further configured such that: a drive motor is fixedly connected to the outer side of the arc segment, and one end of the rotating shaft extends out of the arc segment and is connected to the output shaft of the drive motor.

[0010] The present invention is further configured such that: an arc-shaped groove is provided on the inner wall of the ash hopper, and the guide plate is slidably connected in the arc-shaped groove; when the guide plate slides to the highest point of the arc-shaped groove, the guide plate is located above the air outlet and the guide plate is tilted downward.

[0011] The present invention is further configured such that: a rotating groove is provided on the inner wall of the arc-shaped groove, and a rotating hole communicating with the rotating groove is provided on the outer wall of the ash hopper. A rotating shaft passes through the rotating hole, and the rotating shaft is connected to the guide plate by a connecting rod. The rotation of the rotating shaft can drive the guide plate to slide along the arc-shaped groove.

[0012] The present invention is further configured such that: a forward and reverse motor is fixedly connected to the outer wall of the ash hopper, and the rotating shaft is connected to the output shaft of the forward and reverse motor.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The conveyor blades carry the dust from the ash hopper into the dust collection box. Under normal conditions, the conveyor blades do not rotate, thus serving a separating function. By periodically driving the rotating blades, the rotating blades push the dust from the ash hopper into the dust collection box, preventing excessive dust accumulation in the ash hopper and thus reducing the likelihood of dust being stirred up. The guide plate guides the dust-laden gas, ensuring that when the gas flows into the dust collector body from the air inlet, the gas is generally blown upwards, reducing the possibility of contact with the dust at the bottom of the ash hopper.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Pulse-jet baghouse dust collector, such as Figure 1 , Figure 2 and Figure 3 As shown, the dust collector includes a main body 1 and a dust hopper 2. The main body 1 contains several filter bags, which are installed within it and supported by brackets. The main body 1 also contains blowpipes 3 positioned above and corresponding to the filter bags, with the blowpipes 3 aligned with the openings at the top of the filter bags. The side walls of the main body 1 and the dust hopper 2 are respectively equipped with an air outlet 4 and an air inlet 5. Dust-laden gas enters the dust hopper 2 through the air inlet 5, moves upwards into the main body 1, passes through the filter bags, and exits through the air outlet 4. The filter bags filter dust from the gas. When there is excessive dust on the surface of the filter bags, compressed gas is blown out from the blowpipes 3. This compressed gas is instantly injected into the interior of the filter bags, causing violent expansion and vibration, which dislodges the dust adhering to the surface of the filter bags and causes it to fall into the dust hopper 2 below the filter bags.

[0022] like Figure 2 and Figure 3As shown, a dust collection box 6 is fixedly connected to the bottom of the dust hopper 2. A connecting channel is provided between the dust collection box 6 and the dust hopper 2. A conveyor blade is rotatably connected in the connecting channel. The conveyor blade can carry the dust in the dust hopper 2 into the dust collection box 6. Under normal conditions, the conveyor blade does not rotate, thus the conveyor blade plays a separating role. By driving the rotating blade to rotate at regular intervals, the rotating blade can push the dust in the dust hopper 2 into the dust collection box 6, thus preventing the dust in the dust hopper 2 from becoming too large, thereby preventing dust from being scattered in the dust hopper 2 and reducing the filtration pressure of the filter bag. The connecting channel includes an arc segment, which includes a front wall, a rear wall, and two oppositely arranged arc walls 8. The conveyor blade includes a rotating shaft 9 and several fixedly connected components. The blades 10 on the outer peripheral wall of the rotating shaft 9 have their two ends abutting against the front wall and the rear wall, respectively. In the arc segment, at least two blades 10 abut against the two arc walls 8, respectively. In this embodiment, there are six blades 10. No matter what state the rotating blades are in, there are always two blades 10 abutting against the two arc walls 8, while the blades 10 themselves abut against the front wall and the rear wall. This ensures that dust will not pass through the connecting channel when the rotating shaft 9 is not rotating. A drive motor 11 is fixedly connected to the outer side of the arc segment. One end of the rotating shaft 9 extends out of the arc segment and is connected to the output shaft of the drive motor 11. The drive motor 11 drives the rotating shaft 9 to rotate, thereby ensuring the rotation efficiency of the rotating shaft 9.

[0023] like Figure 2 and Figure 4As shown, a guide plate 7 is also provided on the inner wall of the ash hopper 2. The guide plate 7 is located below the air inlet 5 and is inclined upwards. The guide plate 7 guides the dust-laden gas, so that when the gas flows into the dust collector body 1 from the air inlet 5, the gas is generally blown upwards, thereby reducing the possibility of contact with the dust at the lower end of the ash hopper 2. An arc-shaped groove 12 is opened on the inner wall of the ash hopper 2, and the guide plate 7 is slidably connected in the arc-shaped groove 12. When the guide plate 7 slides to the highest point of the arc-shaped groove 12, the guide plate 7 is located above the air outlet 4 and is inclined downwards. When the filter bag needs to be cleaned, the lower guide plate 7 can be rotated along the arc-shaped groove 12 to the upper end of the air inlet 5. During the movement, the guide plate 7 will flip, thereby reducing the dust residue on the guide plate 7. During the cleaning process, a large amount of dust will flow out from the air outlet 4. The dust collector body 1 enters the ash hopper 2. At this time, the guide plate 7 can block dust from entering the air inlet 5, reducing the amount of dust entering the air inlet 5. A rotating groove 13 is provided on the inner wall of the arc-shaped groove 12. A rotating hole communicating with the rotating groove 13 is provided on the outer wall of the ash hopper 2. A rotating shaft 14 passes through the rotating hole. The rotating shaft 14 is connected to the guide plate 7 by a connecting rod. The rotation of the rotating shaft 14 can drive the guide plate 7 to slide along the arc-shaped groove 12. A forward and reverse motor 15 is fixedly connected to the outer wall of the ash hopper 2. The rotating shaft 14 is connected to the output shaft of the forward and reverse motor 15. The forward and reverse motor 15 drives the rotating shaft 14 to rotate forward or reverse. The connecting rod rotates in the rotating groove 13 under the action of the rotating shaft 14. The rotation of the connecting rod drives the guide plate 7 to make a circular motion along the arc-shaped groove 12, thereby driving the movement of the guide plate 7.
