Description

Technical Field

[0001] This utility model relates to the technical field of water curtain dust collectors, and in particular to a water curtain dust collector for a cigarette cutting machine. Background Technology

[0002] After the shredder discharges tobacco shreds and dust into the water curtain dust collector through negative pressure dust removal, the water curtain dust collector can effectively treat the tobacco shreds and dust, thereby achieving the purpose of purifying the gas.

[0003] For example, Chinese utility model patent application number CN202420386503.6 discloses a water curtain dust collector, which includes a box body and a water collection tray connected to the bottom of the box body. An air inlet is located in the middle of the upper surface of the box body, and an air inlet pipe located inside the box body is connected below the air inlet. A funnel-shaped air collection trough is installed below the air inlet pipe, and a water supply pipe is located in the middle of the bottom of the air collection trough. One end of the water supply pipe extends outside the box body, and the other end communicates with the inside of the air collection trough. By using the air collection trough and high-pressure gas to impact the water surface to create a water curtain, the increased cost of using other spraying methods to create a water curtain is avoided, and unnecessary energy consumption is reduced, thus solving the problems of resource waste and increased operating costs caused by existing technologies.

[0004] The aforementioned water curtain dust collector uses wet dust removal, which can separate dust carried in the gas from the gas, thereby achieving the purpose of purifying the gas. However, wet dust removal mixes all the dust and tobacco with water, which, while achieving the purpose of dust removal, results in a large waste of tobacco. Utility Model Content

[0005] This utility model discloses a water curtain dust collector for cigarette cutting machines, which solves the problem of a large amount of tobacco waste caused by wet dust removal.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A water curtain dust collector for a cigarette cutting machine includes a housing. A partition is fixed at the bottom of the housing. A screening component is provided on the partition, which is in contact with one side of the housing and is used to screen tobacco shreds and dust. A feed inlet located below the screening component is connected to the side of the housing near the screening component. A discharge hopper corresponding to the screening component is connected to the bottom of the housing. A vertical plate connected to the top of the housing is provided on the side of the partition away from the screening component. A water collection tray corresponding to the vertical plate is connected to the bottom of the housing.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] When tobacco shreds and dust enter the chamber through the feed inlet, the dust passes through the screening component with the airflow. The screening component can separate the tobacco shreds and dust, while the tobacco shreds are blocked by the screening component and fall downwards. After passing through the screening component with the airflow, the dust enters between the vertical plate and the partition plate, and then comes into contact with the water in the chamber, thus completing the dust treatment. This utility model can effectively separate tobacco shreds from dust and properly recycle the clean tobacco shreds, which plays a good role in energy conservation and efficiency improvement for the country and cigarette factories.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a water curtain dust collector for a cigarette cutting machine, including a housing 1. A partition 2 is fixed at the bottom of the housing 1. The partition 2 is provided with a screening component that contacts one side of the housing 1 and is used to screen tobacco shreds and dust. The side of the housing 1 near the screening component is connected to a feed inlet 11 located below the screening component. The bottom of the housing 1 is connected to a discharge hopper 5 corresponding to the screening component. The side of the partition 2 away from the screening component is provided with a vertical plate 6 connected to the top of the housing 1. The bottom of the housing 1 is connected to a water collection tray 7 corresponding to the vertical plate 6. After the tobacco and dust enter the housing 1 through the feed inlet 11, the partition 2, in conjunction with the screening component, can screen the tobacco and dust. The dust passes through the screen holes on the screening component and enters between the vertical plate 6 and the partition 2 with the airflow, and then falls into the water in the housing 1 (there is a certain gap between the top of the partition 2 and the top of the housing 1, and a certain gap between the bottom of the vertical plate 6 and the bottom of the housing 1). After the tobacco and dust are screened, the clean tobacco can be discharged through the feed hopper 5, and the water mixed with dust in the housing 1 can be discharged through the water collection tray 7.

[0017] like Figure 2 and Figure 3 As shown, the screening assembly includes a connecting plate 3 disposed on the side of the partition 2 away from the vertical plate 6. The other side of the connecting plate 3 contacts the inner wall of the housing 1. An opening is provided on the connecting plate 3, and a rotating cylinder 4 is rotatably connected to the opening. The rotating cylinder 4 has perforations. Two symmetrical baffles 32 are fixed to the bottom of the connecting plate 3, and the opposing surfaces of the two baffles 32 contact the two sides of the rotating cylinder 4 respectively. When dust enters the housing 1 and moves upward with the airflow, the dust and airflow can pass through the perforations on the rotating cylinder 4 and move between the vertical plate 6 and the partition 2. The two baffles 32 can block the two sides of the rotating cylinder 4 located below the connecting plate 3, preventing dust or tobacco from entering. Subsequently, the rotation of the rotating cylinder 4 can prevent the rotating cylinder 4 from always screening dust in one part, allowing other parts of the rotating cylinder 4 to screen dust, avoiding the need for frequent cleaning by workers after the perforations on the rotating cylinder 4 become clogged.

[0018] like Figure 2 and Figure 3 As shown, the connecting plate 3 is inclined toward the partition plate 2, and a cleaning brush 31 is fixed inside the opening of the connecting plate 3 near the partition plate 2, which contacts the outer wall of the rotating drum 4. When the rotating drum 4 rotates, the cleaning brush 31 can clean the surface of the rotating drum 4, brushing off the dust adhering to the rotating drum 4. The dust then falls between the vertical plate 6 and the partition plate 2 through the inclined connecting plate 3, eliminating the need for manual cleaning of the rotating drum 4 and preventing the perforations on the rotating drum 4 from becoming clogged, which would affect the screening effect of tobacco and dust.

[0019] like Figure 3 and Figure 4As shown, a drive motor 34 is fixed on the connecting plate 3, a rotating rod 35 is fixed on the rotating shaft of the drive motor 34, and a connecting rod 41 connected to the rotating rod 35 is fixed inside the rotating drum 4; a storage battery 36 is fixed on the connecting plate 3. The drive motor 34 can drive the rotating rod 35 to rotate, which in turn causes the connecting rod 41 to drive the rotating drum 4 to rotate; the storage battery 36 can supply power to the drive motor 34.

[0020] like Figure 2 and Figure 3 As shown, both the partition 2 and the inner wall of the box 1 are fixed with bearing blocks 21, and the connecting plate 3 is connected to the bearing blocks 21 by bolts. The top plate of the box 1 is connected to the box 1 by screws. After the workers separate the top plate of the box 1 from the box 1, they can remove the bolts on the connecting plate 3 and take the connecting plate 3 out of the box 1 for inspection and maintenance.

[0021] like Figure 3 As shown, cleaning cotton 33 is fixed to the opposite surfaces of the two baffles 32, and it contacts the inner wall of the rotating drum 4. The connecting rod 41 is located between the two cleaning cotton 33. The cleaning cotton 33 can clean the inner wall of the rotating drum 4 and prevent dust from accumulating on the inner wall of the rotating drum 4.

[0022] like Figure 1 and Figure 2 As shown, a discharge valve 51 is installed at the discharge end of the hopper 5; a fan 12 is fixed on the top of the housing 1, and the connection between the suction end of the fan 12 and the housing 1 is located on the side of the vertical plate 6 away from the partition plate 2. After the tobacco and dust are screened, the discharge valve 51 can be opened to discharge the tobacco, and after the fan 12 is started, the purified air inside the housing 1 is discharged.

[0023] like Figure 2 As shown, a circular shaft 61 in the same direction is fixed to the side of the vertical plate 6 away from the partition plate 2, close to the water collection tray 7. Below the circular shaft 61, a wind-collecting plate 62 is fixed inside the housing 1. A water-blocking grille 8 is fixed inside the housing 1 above the circular shaft 61. The wind-collecting plate 62 includes a vertical part and an arc-shaped part fixed to the vertical part. The wind-collecting plate 62, in conjunction with the circular shaft 61, forces the water curtain to pass only through the middle layer between the wind-collecting plate 62 and the circular shaft 61 when the water in the housing 1 is blown up under the huge wind pressure of the dust-laden gas. This keeps the water curtain as horizontal as possible and prevents it from being too high, thus affecting its secondary dust removal effect. The water-blocking grille 8 is mainly to prevent the water curtain generated by the wind pressure from being too high, and to prevent water from being discharged from the housing 1 through the connection between the housing 1 and the fan 12, which would cause the water level to drop too quickly and thus waste water resources.

[0024] like Figure 1As shown, the drain end of the water collection tray 7 is connected to a drain pipe 71. Above the drain pipe 71 is an overflow water tank 72 connected to the tank body 1. The drain end of the overflow water tank 72 is connected to the drain pipe 71. Inside the tank body 1, a cover 73 is fixed, covering the connection between the overflow water tank 72 and the tank body 1. The bottom of the cover 73 is open and located inside the water collection tray 7. A valve is installed on the drain pipe 71, which can be opened to drain the water in the water collection tray 7. The overflow water tank 72 prevents the water level in the tank body 1 from becoming too high, and the cover 73 effectively seals the connection between the overflow water tank 72 and the tank body 1.

[0025] like Figure 1 As shown, a water tank 9 corresponding to the water collection tray 7 is fixed to one side of the housing 1. A water supply pipe 91 connected to the housing 1 is connected to the water tank 9. The housing 1 is provided with an observation window 13 and an inspection door 14. After water is injected into the water tank 9, the water enters the housing 1 through the water supply pipe 91. The staff can observe the situation inside the housing 1 through the observation window 13. The staff can open the inspection door 14 to inspect the interior of the housing 1. There are two inspection doors 14, located on both sides of the housing 1.

[0026] When tobacco and dust enter the housing 1 through the feed inlet 11, the dust passes through the perforations on the rotating drum 4 with the airflow, which can screen the tobacco and dust. The tobacco is blocked by the rotating drum 4 and falls downwards; the dust enters between the vertical plate 6 and the partition plate 2, and then comes into contact with the water in the housing 1 to complete the dust treatment. When the external shredder is working, it will generate sparks during the sharpening process. The dry dust removal system needs to be equipped with fire dampers, explosion-proof valves and spark detectors, which poses certain safety hazards. Nowadays, after the tobacco and dust are separated, the dust is treated by wet treatment, which effectively eliminates the safety hazards caused by sparks.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
