Description

Technical Field

[0001] This application relates to the field of flue gas dust removal technology, and in particular to a dust discharge mechanism for a bag filter. Background Technology

[0002] Baghouse dust collectors are a type of efficient and widely used dry dust collection equipment. Their core function is to filter dust-laden gas. The inside of the housing is usually under negative pressure (or slightly positive pressure). By filtering the dust-laden gas through filter bags, dust and gas are separated. The separated dust settles in the ash hopper at the bottom of the baghouse dust collector housing.

[0003] The existing bag filter dust collector ash discharge device with application number 202420418152.2 monitors the weight of dust in real time through a weighing sensor. When the weight reaches a preset threshold, the controller automatically starts the motor to open the left and right wing valves to discharge ash. However, since the inside of the bag filter is usually under negative pressure (or slightly positive pressure) when the bag filter is working, the machine needs to be stopped before the ash discharge can be completed. Otherwise, it will lead to gas leakage, which will affect the dust removal efficiency. Utility Model Content

[0017] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] See Figures 1 to 4 To further elaborate on this application: Combination Figure 1 The dust removal mechanism of the baghouse dust collector includes a dust collection box A with a dust discharge port B at the bottom. A dust discharge module C is installed on the dust discharge port B. The dust discharge module C is used to discharge dust that has settled in the conical dust hopper at the bottom of the box A. The box A contains several filter bags. Gas carrying dust enters the box A through the air inlet, is filtered by the filter bags, and the dust is retained in the conical dust hopper within the box A. Clean air is discharged through the exhaust port.

[0019] Combination Figure 2 and Figure 3 The ash removal module C includes a housing 10 and at least two sealing bodies (20A, 20B) rotatably connected to the housing 10; wherein the sealing bodies (20A, 20B) are spherical; the housing 10 is provided with an ash removal channel 100 communicating with the ash removal port B.

[0020] The sealing bodies (20A, 20B) are provided with material passages 200, and adjacent material passages 200 are staggered. The material passages 200 may be spherical.

[0021] The sealing bodies (20A, 20B) are sequentially arranged in the ash discharge channel 100, and a storage cavity 110 for accommodating dust is formed between the sealing bodies (20A, 20B). The sealing bodies (20A, 20B) can rotate, so that the material passage 200 alternately communicates with the ash discharge channel 100.

[0022] In this embodiment, two sealing bodies are used as an example for illustration. The sealing bodies (20A, 20B) include a first sealing body 20A and a second sealing body 20B arranged sequentially along the ash discharge channel 100. The first sealing body 20A and the second sealing body 20B can be opened alternately in sequence; that is, at the same time, only one of the sealing bodies is in the open state (the ash discharge channel 100 is connected to the material passage channel 200).

[0023] Combination Figure 4Under normal circumstances, the first sealing body 20A is in the closed state; the second sealing body 20B is in the open state.

[0024] During operation, the first sealing body 20A opens, connecting the material passage 200 on it with the ash discharge passage 100, thereby connecting the ash hopper with the storage cavity 110. The dust in the ash hopper enters the storage cavity 110 through the first sealing body 20A. At the same time as the first sealing body 20A opens, the second sealing body 20B closes, disconnecting the material passage 200 on it from the ash discharge passage 100, thereby disconnecting the storage cavity 110 from the outside.

[0025] Then, the first sealing body 20A closes, disconnecting the ash hopper from the storage cavity 110 and cutting off the communication between the ash hopper and the storage cavity 110. At the same time as the first sealing body 20A closes, the second sealing body 20B opens, connecting the storage cavity 110 to the outside and discharging the dust in the storage cavity 110.

[0026] This application has a dust discharge module C arranged at the dust discharge port B. By alternately opening two sealing bodies (20A, 20B), the dust in the housing A is discharged, which can ensure that the bag filter can continue to perform dust removal work during the dust discharge process, thereby greatly improving the dust removal efficiency.

[0027] Combination Figure 2 In this embodiment, a linkage assembly 30 is provided on the outer side of the housing 10. The linkage assembly 30 is used to drive the sealing bodies (20A, 20B) to rotate. The linkage assembly 30 includes a rotating component 310, a driving component 320, and a power component 330 that drives the driving component 320. The driving component 320 is connected to the rotating component 310 via a transmission connection. Specifically, the rotating component 310 is a gear; the driving component 320 is a rack; and the power component 330 is a double-rod cylinder. The power component 330 drives the rack to move linearly, and the rack drives the sealing bodies to rotate through the gear. Of course, the power component 330 can also be a single-rod cylinder.

[0028] Combination Figure 3In this embodiment, the driving component 320 is provided with a first transmission structure 3210 and a second transmission structure 3220 that mesh with the sealing bodies (20A, 20B). The first transmission structure 3210 is matched with the first sealing body 20A, and the second transmission structure 3220 is matched with the second sealing body 20B. Both the first transmission structure 3210 and the second transmission structure 3220 have a plurality of gear teeth. The sealing bodies (20A, 20B) mesh and transmit power with the first transmission structure 3210 and the second transmission structure 3220, respectively.

[0029] Under normal conditions, the rotating component 310 on the first sealing body 20A is engaged with the first transmission structure 3210; the rotating component 310 on the second sealing body 20B is disengaged from the second transmission structure 3220.

[0030] During ash discharge, the power component 330 drives the drive component 320 to move upward. The drive component 320 first drives the first sealing body 20A to rotate, so that the material passage 200 on it is closed. Then, the second transmission structure 3220 contacts and engages with the rotating component 310 on the second sealing body 20B, driving the second sealing body 20B to rotate and open.

[0031] It should be noted that when the rotating component 310 completes the first transmission structure 3210, the first sealing body 20A rotates 90 degrees accordingly. When the rotating component 310 completes the second transmission structure 3220, the second sealing body 20B rotates 90 degrees accordingly.

[0032] Combination Figure 2 The aforementioned sealing bodies (20A, 20B) are rotatably connected to the housing 10; wherein each of the sealing bodies (20A, 20B) is provided with a rotating shaft 210, the rotating shaft 210 being rotatably connected to the housing 10, and the linkage assembly 30 being connected to the rotating shaft. Specifically, the rotating components 310 are respectively provided on the rotating shaft and are used to drive the sealing bodies (20A, 20B) to rotate.

[0033] In some embodiments, the driving component 320 may be a pinion gear, and the power component 330 may be a motor; the motor drives the pinion gear to rotate, which in turn drives the sealing body to rotate.

[0034] Combination Figure 2 To reduce space requirements, a connecting plate 50 connects the power component 330 and the drive component 320; the power component 330 and the drive component 320 are arranged parallel to each other on both sides of the rotating component 310. This arrangement greatly reduces the space occupied by the linkage assembly 30.

[0035] In some embodiments, a protective shell rotatably connected to the housing 10 is further included, the protective shell covering the outside of the linkage assembly 30. This prevents dust from affecting the stable operation of the linkage assembly 30.

[0036] Combination Figure 4 In this embodiment, adjacent material passages 200 are arranged vertically. Thus, when one of the sealing bodies is open, the other sealing body is closed, thereby enabling the bag filter to continuously remove dust during the material discharge process and improving dust removal efficiency.

[0037] Combination Figure 3 The housing 10 is further provided with a plurality of limiting components 60 for supporting and guiding the movement of the drive component 320. The limiting components 60 are located on the side of the drive component 320 away from the rotating component 310 to prevent the drive component 320 from shaking. The limiting components 60 are cam followers.

[0038] Combination Figure 4 The ash discharge channel 100 is provided with a placement groove 40, and the sealing bodies (20A, 20B) are correspondingly placed in the placement groove 40. The placement groove 40 is spherical and matches the sealing bodies (20A, 20B). A certain gap is left between the sealing bodies (20A, 20B) and the placement groove 40 to facilitate the rotation of the sealing bodies within the placement groove 40.

[0039] Combination Figure 4 To prevent gas leakage from the housing A through the gap between the sealing body and the placement groove 40, a sealing element 70 is also provided in the placement groove 40. The sealing element 70 is located between the housing 10 and the sealing body and is used to fill the gap between the sealing element 70 and the housing 10. The placement groove 40 has an annular mounting groove, and the sealing element 70 is installed in the annular mounting groove to abut against the sealing body. The sealing element 70 not only prevents gas leakage from the housing A but also blocks dust, preventing dust from entering the gap between the sealing body and the placement groove 40.

[0040] In some embodiments, a control device is also included, which is electrically connected to the ash removal module C. The control device controls the power component 330 to drive the sealing body to rotate and open alternately, thereby periodically cleaning the dust inside the housing.
