Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and specifically to a combined baghouse dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] Currently used baghouse dust collectors typically use high-pressure air blowing from the top to blow away the fine dust adsorbed on the surface of the bags. The fine dust then slides down the ash hopper for collection. However, in actual use, the bags are mostly long and cylindrical, so the air blown in from the top has less impact on the parts closer to the bottom of the bag, resulting in less effective dust removal. Therefore, a combined baghouse dust collector that can more effectively handle fine dust is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a combined bag filter to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A combined bag filter dust collector includes a housing. A dust hopper is fixedly connected to and internally communicates with the bottom of the housing. Support legs are fixedly connected to the four corners of the outer surface of the housing. A partition is fixedly connected to the interior of the housing near the top. An air blower is installed on the outer surface of the housing above the partition. Several air supply pipes are fixedly connected to the air blower. These air supply pipes penetrate the side walls of the housing and extend above the partition. Several placement holes are arrayed inside the partition. Filter bags are placed inside each placement hole. A support frame is fitted inside each filter bag. A fixing block is fixedly connected to two connecting rods of the support frame. A connecting block is fixedly connected to the upper surface of the fixing block. The middle part of a rotating rod is rotatably connected to the top of the connecting block. A counterweight and a hammer are fixedly connected to both ends of the rotating rod, respectively. A windward plate is fixedly connected to the upper surface of the hammer. High-pressure air outlets are fixedly connected to each air supply pipe above the windward plate, and the high-pressure air outlets blow air vertically downwards.

[0007] Furthermore, taking the connection point between the connecting block and the rotating rod as the fulcrum, the force on one side of the counterweight is greater than the force on the hammer and the windward plate.

[0008] Furthermore, a limiting block is fixedly connected to the side of the connecting block below the side of the rotating rod near the counterweight block, and the limiting block contacts the lower surface of the rotating rod.

[0009] Furthermore, a sound insulation layer is fixedly connected to the outer surface of the enclosure.

[0010] Furthermore, a wind baffle is fixedly connected inside the ash hopper.

[0011] Furthermore, a connecting pipe is fixedly connected to the bottom outlet of the ash hopper, a connecting pipe is threadedly connected to the bottom end of the connecting pipe, and a collection box is fixedly connected to and internally communicated with the bottom of the connecting pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses a high-pressure air nozzle to blow air downwards, causing a hammer to strike the connecting block. This, in turn, causes the fixing block, support frame, and cloth bag to vibrate, dislodging the dust adhering to the surface. Subsequent high-pressure air blown into the cloth bag loosens the dust and escapes through the gaps. Therefore, the primary method is to strike the support frame to vibrate the cloth bag and dislodge the dust, while the subsequent air blowing in carries away any remaining dust, resulting in a better overall dust removal effect for the cloth bag.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, a combined bag filter dust collector includes a housing 1. A dust hopper 2 is fixedly connected to and internally connected to the bottom of the housing 1. Support legs 3 are fixedly connected to the four corners of the outer surface of the housing 1. A partition 4 is fixedly connected to the interior of the housing 1 near the top. An air blower 5 is installed on the outer surface of the housing 1 above the partition 4. Several air supply pipes 6 are fixedly connected to the air blower 5, all of which penetrate the side walls of the housing 1 and extend above the partition 4. Several placement holes 22 are arrayed inside the partition 4. A filter bag 8 is placed inside each placement hole 22. The filter bag 8 is made of a relatively rigid material, and its top has a rigid ring to prevent it from falling out of the placement hole 22. A support frame 9 is fitted inside the filter bag 8. The connecting rod of the support frame 9 is a slightly outwardly curved arc with a certain deformation capacity, allowing the connecting rod to contract when inserted into the placement hole 22 and then expand to open the filter bag 8, facilitating vibration of the filter bag 8 by the support frame 9. Two connecting rods of the support frame 9 are fixedly connected to fixing blocks. 10. A connecting block 11 is fixedly connected to the upper surface of the fixed block 10. The middle part of the rotating rod 12 is rotatably connected to the top of the connecting block 11. The two ends of the rotating rod 12 are respectively fixedly connected to a counterweight block 13 and a hammer 14. A windproof plate 15 is fixedly connected to the upper surface of the hammer 14. A high-pressure air inlet 7 is fixedly connected to the air supply pipe 6 above the windproof plate 15. The high-pressure air inlet 7 blows air vertically downwards, and unfiltered air is introduced into the box 1 through the air inlet pipe. When the filter bag 8 is full of powder... When dust is present, the air blower 5 is activated, blowing air downwards from the high-pressure air outlet 7 for three to four seconds each time. During this time, the air-facing plate 15 is impacted by the air, causing it to rotate around the connection point between the connecting block 11 and the rotating rod 12, and the hammer 14 strikes the connecting block 11. This, in turn, causes the fixing block 10, the support frame 9, and the cloth bag 8 to vibrate, knocking off the dust adhering to the surface. The high-pressure air blown into the cloth bag 8 after the dust is loosened by the vibration will blow out from the gaps, further carrying away the remaining dust. Thus, the primary method is to knock off the dust by striking the support frame 9, while the subsequent air blowing in carries away the remaining dust, resulting in a better overall dust removal effect for the cloth bag 8.

[0022] like Figure 4 As shown, in some embodiments, with the connection point between the connecting block 11 and the rotating rod 12 as the fulcrum, the force on one side of the counterweight 13 is greater than the force on one side of the hammer 14 and the wind vane 15. Specifically, this ensures that after the hammer 14 strikes, it automatically returns to its original position due to the counterweight 13, making it easier to strike again during the next high-pressure air blowing. In actual use, the force on one side of the counterweight 13 only needs to be slightly greater than that on the hammer 14, thus making it easier for the high-pressure air to blow the hammer 14.

[0023] like Figure 4 As shown, in some embodiments, the side of the connecting block 11 is fixedly connected to a limiting block 16 below the side of the rotating rod 12 near the counterweight block 13. The limiting block 16 contacts the lower surface of the rotating rod 12. Specifically, the installed limiting block 16 prevents the counterweight block 13 from swinging downward after resetting, thereby keeping the windward plate 15 horizontal and allowing it to face the wind over a larger area.

[0024] like Figure 1 As shown, in some embodiments, a sound insulation layer 17 is fixedly connected to the outer surface of the housing 1. Specifically, the sound insulation layer 17 reduces the noise transmitted during knocking, thereby reducing noise pollution. In actual use, the ash hopper 2 and the air inlet and outlet can be wrapped with the sound insulation layer 17 to improve the sound insulation effect.

[0025] like Figure 2 As shown, in some embodiments, a baffle plate 18 is fixedly connected inside the ash hopper 2. Specifically, the dust temporarily accumulated by the installed baffle plate 18 falls below the baffle plate 18, thereby effectively preventing too much fine dust from being blown up and re-adsorbed onto the surface of the cloth bag 8 when unfiltered air is reintroduced.

[0026] like Figure 5 As shown, in some embodiments, a connecting pipe 19 is fixedly connected to the bottom outlet of the ash hopper 2, and a connecting pipe 20 is threadedly connected to the bottom end of the connecting pipe 19. A collection box 21 is fixedly connected to and internally communicates with the bottom of the connecting pipe 20. Specifically, dust is collected through the collection box 21, and the collection box 21 is unscrewed for cleaning by timed or quantitative methods. In actual use, a glass window can be provided on the side wall of the collection box 21 to facilitate real-time observation of the accumulation inside.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
