Description
Technical Field
[0001] This utility model relates to the technical field of tobacco dust removal equipment, and in particular to a switching device and a tobacco dust collector. Background Technology
[0002] The tobacco production process generates a large amount of smoke and dust, which is currently treated and purified using tobacco dust collectors to reduce environmental pollution. To determine whether the tobacco dust collector has removed useful tobacco shreds and stems, workers need to randomly inspect the impurities drawn in. Existing tobacco dust collectors include a connected suction mechanism and an ash hopper. The dust and impurities drawn in by the suction mechanism enter the ash hopper, which collects these impurities. The ash hopper includes an ash discharge valve, the outlet of which is connected to a centralized collection pipeline. The centralized collection pipeline is always under negative pressure, allowing dust and impurities to enter and ultimately be discharged through it.
[0003] When staff conduct spot checks and maintenance on the centralized collection pipeline, it is necessary to disassemble the pipe connecting the ash discharge valve outlet to the centralized collection pipeline. To ensure timely spot checks, staff usually disassemble the pipe while the tobacco dust collector is operating and the centralized collection pipeline is under negative pressure. Since the centralized collection pipeline is constantly under negative pressure, the pipe is also constantly under negative pressure, making installation and disassembly difficult and consuming a significant amount of manpower. Furthermore, during pipe disassembly, staff may come into contact with rotating parts inside the ash discharge valve, potentially leading to a safety accident.
[0004] Therefore, there is an urgent need for a switching device and a tobacco dust collector to solve the above-mentioned technical problems. Utility Model Content
[0005] The first objective of this invention is to provide a switching device that can solve the problem that when sampling and inspecting impurities sucked by tobacco dust collectors, workers disassemble the pipes while the pipes are under negative pressure. This disassembly and installation of the pipes is relatively difficult and consumes a lot of manpower. At the same time, workers may come into contact with the rotating parts inside the ash discharge valve during pipe disassembly, which could lead to safety accidents.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A switching device is installed between an ash discharge valve below an ash hopper and a centralized collection pipe, the switching device comprising:
[0008] The housing includes a first pipe, a second pipe, and a third pipe connected in a "Y" shape. The first pipe is connected to the ash discharge valve, the second pipe can be selectively blocked by a sealing component, and the third pipe is connected to the centralized collection pipe.
[0009] An adjusting component includes a baffle and a rotating component. The baffle is positioned at the intersection of the first pipeline, the second pipeline, and the third pipeline. The rotating component can drive the baffle to rotate to selectively block the second pipeline and the third pipeline. The rotating component includes a limiting hole, which includes a first sidewall and a second sidewall.
[0010] A locking member passes through the limiting hole and connects to the mounting hole of the housing. The locking member can selectively lock the rotating member. When the first sidewall is in contact with the locking member, the baffle blocks the second pipeline. When the second sidewall is in contact with the locking member, the baffle blocks the third pipeline.
[0011] As a preferred technical solution for the switching device, the sealing component includes a sealing cap and at least two quick-release buckles. The sealing cap has a shape consistent with the shape of the second pipeline outlet and can cover the second pipeline outlet. At least two quick-release buckles are spaced apart on the outer side wall of the sealing cap. The side wall of the housing is provided with hooks corresponding to the quick-release buckles. The quick-release buckles can selectively hook onto the hooks.
[0012] As a preferred technical solution for the switching device, the sealing component further includes a sealing gasket, which is fitted and placed inside the sealing cover.
[0013] As a preferred technical solution for the switching device, the rotating component includes a rotating shaft and a handle. The rotating shaft is placed between the second pipeline and the third pipeline and passes through the housing. The baffle is fixedly connected to the rotating shaft, and one end of the rotating shaft is connected to the handle.
[0014] As a preferred technical solution for the switching device, the rotating component further includes two bearings, and the housing is provided with two mounting holes facing each other. The two bearings are respectively placed in the two mounting holes, and the two ends of the rotating shaft are respectively fixed to the inner rings of the two bearings.
[0015] As a preferred technical solution for the switching device, the handle includes a head and a rod, the head being opposite to the housing, and the limiting hole being located in the head.
[0016] As a preferred technical solution for the switching device, the limiting hole is an arc-shaped hole.
[0017] As a preferred technical solution for the switching device, the first pipeline and the second pipeline intersect at line a, and the first pipeline and the third pipeline intersect at line b. The included angle determined with the rotating shaft as the center and the lines a and b as constraints is the central angle of the arc-shaped hole.
[0018] As a preferred technical solution for the switching device, the switching device further includes a viewing window, which is disposed in the housing and faces the side of the baffle.
[0019] The second objective of this utility model is to provide a tobacco dust collector. To achieve this objective, the utility model adopts the following technical solution:
[0020] A tobacco dust collector includes a switching device as described in any of the above claims, the switching device being assembled between an ash discharge valve below the ash hopper and a centralized collection pipe in the tobacco dust collector.
[0021] The beneficial effects of this utility model are as follows:
[0022] The switching device provided by this utility model is installed between the ash discharge valve and the centralized collection pipe below the ash hopper in a tobacco dust collector. The housing is designed in a "Y" shape, connecting the first, second, and third pipes. A baffle is placed at the intersection of the first, second, and third pipes. When the operator operates the rotating component, the baffle can selectively block the second and third pipes. When dust and impurities to be sucked into the centralized collection pipe, the operator can operate the rotating component to block the second pipe, at which point the first and third pipes are connected, and the dust and impurities will enter the centralized collection pipe. When it is necessary to sample and inspect the dust and impurities, the operator can operate the rotating component and simultaneously remove the sealing component from the second pipe, causing the baffle to block the third pipe. At this point, the first and second pipes are connected, and the dust and impurities will leak out from the second pipe. The operator can then quickly determine whether the impurities are mixed with tobacco shreds and stems. In this way, when inspecting the extracted dust and impurities, staff only need to operate the rotating component to control the discharge of dust and impurities through the second pipeline. This avoids the need for staff to install or disassemble the pipeline under negative pressure, reducing labor costs. Simultaneously, it prevents staff from touching the rotating parts inside the ash discharge valve, improving worker safety. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] Example 1:
[0036] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a switching device installed between the ash discharge valve and the centralized collection pipe below the ash hopper in the tobacco dust collector. The switching device includes a housing 1, an adjusting component 2, and a locking component 3. The housing 1 includes a first pipe 11, a second pipe 12, and a third pipe 13 connected in a "Y" shape. The first pipe 11 is connected to the ash hopper, the second pipe 12 can be selectively blocked by the blocking component 4, and the third pipe 13 is connected to the centralized collection pipe. The adjusting component 2 includes a baffle 21 and a rotating component 22. The baffle 21 is placed at the intersection of the first pipe 11, the second pipe 12, and the third pipe 13. The rotating component 22 can drive the baffle 21 to rotate, so as to selectively block the second pipe 12 and the third pipe 13. The rotating component 22 includes a limiting hole 220, which includes a first sidewall and a second sidewall. The locking component 3 passes through the limiting hole 220 and is connected to the mounting hole of the housing 1. The locking component 3 can selectively lock the rotating component 22 to lock the position of the baffle 21 inside the housing 1. When the rotating part 22 moves, it not only drives the baffle 21 to rotate, but also the limiting hole 220 moves accordingly. When the first side wall is in contact with the locking part 3, the baffle 21 blocks the second pipe 12. When the second side wall is in contact with the locking part 3, the baffle 21 blocks the third pipe 13.
[0037] The switching device provided in this embodiment is installed between the ash discharge valve and the centralized collection pipe below the ash hopper in the tobacco dust collector. By designing the housing 1 in a "Y" shape to connect the first pipe 11, the second pipe 12, and the third pipe 13, and placing the baffle 21 at the intersection of the first pipe 11, the second pipe 12, and the third pipe 13, when the operator operates the rotating component 22, the baffle 21 can selectively block the second pipe 12 and the third pipe 13. When the dust and impurities to be sucked enter the centralized collection pipe, the operator can... Operating the rotating component 22 causes the baffle 21 to block the second pipe 12. At this time, the first pipe 11 and the third pipe 13 are connected, and dust and impurities will enter the centralized collection pipe. When it is necessary to sample and inspect the dust and impurities, the operator can operate the rotating component 22 and remove the sealing component 4 from the second pipe 12, causing the baffle 21 to block the third pipe 13. At this time, the first pipe 11 and the second pipe 12 are connected, and the dust and impurities will leak out from the second pipe 12. The operator can then quickly determine whether the impurities are mixed with tobacco shreds and stems. In this way, when sampling and inspecting the sucked dust and impurities, the operator only needs to operate the rotating component 22 to control the dust and impurities to leak out from the second pipe 12, avoiding the need for the operator to install and disassemble the pipe under negative pressure, thus reducing labor costs. At the same time, it also avoids the operator touching the rotating parts inside the ash discharge valve, improving the operator's work safety.
[0038] By providing a limiting hole 220 on the rotating component 22 and a locking component 3, the rotation angle of the baffle 21 can be limited. The first and second sides of the limiting hole 220 are the extreme positions of the rotation angle of the baffle 21. The limiting hole 220 prevents the baffle 21 from being deformed due to excessive rotation angle when the operator operates the rotating component 22 to drive it to rotate. This extends the service life of the baffle 21 and, consequently, the service life of the switching device. The locking component 3 can selectively lock the rotating component 22, thus locking the position of the baffle 21. This eliminates the need for the operator to control the rotating component 22 in real time, further reducing the workload of the operator. In this embodiment, the locking component 3 can be a bolt.
[0039] In this embodiment, the first pipe 11, the second pipe 12 and the third pipe 13 are connected to each other by welding to form the shell 1.
[0040] In this embodiment, the first pipeline 11 is fixedly connected to the ash discharge valve below the ash hopper by bolts.
[0041] Exemplarily, the sealing component 4 includes a sealing cap 41 and at least two quick-release buckles 42. The shape of the sealing cap 41 is consistent with the outlet shape of the second pipe 12 and can cover the outlet of the second pipe 12. The at least two quick-release buckles 42 are spaced apart on the outer wall of the sealing cap 41. At the same time, a hook 14 corresponding to the quick-release buckle 42 is provided on the side wall of the housing 1. The quick-release buckle 42 can selectively hook with the hook 14. When the operator needs to sample and inspect the sucked dust and impurities, he only needs to operate the quick-release buckle 42 to disengage the quick-release buckle 42 from the hook 14, and the sealing component 4 can be removed from the outlet of the second pipe 12. The sucked dust and impurities can then be discharged from the outlet of the second pipe 12. The quick-release buckle 42 can be fixed to the outer wall of the sealing cap 41 by bolts or by welding, without specific limitations. The quick-release buckle 42 is a standard component. For details regarding its structure and working principle, please refer to existing technologies; further details will not be elaborated here. The sealing component 4 also includes a sealing gasket 43, which is fitted inside the sealing cover 41 to further improve the sealing performance between the sealing cover 41 and the outlet of the second pipeline 12. The sealing gasket 43 can be made of rubber.
[0042] For example, the rotating component 22 includes a rotating shaft 221 and a handle 222. The rotating shaft 221 is positioned between the second pipe 12 and the third pipe 13 and passes through the housing 1. The baffle 21 is fixedly connected to the rotating shaft 221, and one end of the rotating shaft 221 is connected to the handle 222. By rotating the handle 222, the rotating shaft 221 can be driven to rotate, thereby causing the baffle 21 to rotate. This allows the baffle 21 to rotate within the space where the first pipe 11, the second pipe 12, and the third pipe 13 intersect, selectively blocking the second pipe 12 and the third pipe 13. The handle 222 makes it easier for operators to operate the rotating component 22 and facilitates the rotation of the baffle 21.
[0043] Furthermore, the rotating component 22 also includes two bearings. Two mounting holes are provided opposite to each other on the housing 1, and the two bearings are respectively placed in the two mounting holes. The two ends of each bearing are fixed to the inner rings of the two bearings. Thus, when the operator turns the handle 222 to drive the rotating shaft 221 to rotate, the rotation of the rotating shaft 221 can be made relatively smoother, further improving the rationality of the switching device design.
[0044] For example, the handle 222 includes a head 2221 and a rod 2222, wherein the head 2221 is opposite to the housing 1, and a limiting hole 220 is located in the head 2221. When the operator rotates the handle 222 via the rod 2222, the head 2221 will rotate accordingly, and the first or second sidewall of the limiting hole 220 will fit against the locking member 3. This allows the limiting hole 220 to be reasonably arranged on the handle 222, further improving the rationality of the handle 222 design.
[0045] In this embodiment, the limiting hole 220 is an arc-shaped hole. When the operator rotates the handle 222, the handle 222 rotates around the pivot 221, and the rotation trajectory of the head 2221 of the handle 222 is an arc. Designing the limiting hole 220 as an arc-shaped hole ensures that the locking member 3 can completely fit with the first or second sidewall of the limiting hole 220, further improving the rationality of the structural design of the rotating member 22. In this embodiment, the intersection line of the first pipe 11 and the second pipe 12 is denoted as line a, and the intersection line of the first pipe 11 and the third pipe 13 is denoted as line b. The included angle determined by the pivot 221 as the center and the limiting angles of lines a and b is the central angle of the arc-shaped hole. In this embodiment, the central angle of the arc-shaped hole is 90°.
[0046] In this embodiment, the switching device also includes a viewing window 5, which is disposed on the housing 1 and faces the side of the baffle 21. Through the viewing window 5, the operator can observe whether the sucked dust and impurities contain tobacco shreds and stems, further improving the convenience of the operator's work. The viewing window 5 is a standard design feature of the equipment, and its specific structure will not be described in detail here.
[0047] Example 2:
[0048] This embodiment provides a tobacco dust collector, including the switching device in Embodiment 1, wherein the switching device is installed between the ash discharge valve below the ash hopper and the centralized collection pipe in the tobacco dust collector.
[0049] The tobacco dust collector provided in this embodiment allows workers to quickly inspect the dust and impurities sucked up by the tobacco dust collector without disassembling any parts, effectively reducing manpower consumption and the risk of dust and impurities entering the workers' respiratory tract. It also prevents workers from coming into contact with the rotating parts inside the ash discharge valve when disassembling the pipes, thus improving the workers' work safety.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
