Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and in particular to a cleaning device and method for pipelines in a tobacco production workshop. Background Technology

[0002] During the tobacco processing, the high-temperature and high-humidity gas discharged from the pipes leading to the tobacco production workshop carries tobacco dust. As a result, after a period of production, tobacco sludge will accumulate in the pipes, which will affect the exhaust efficiency of the pipes and may even flow back to the outlet vibrating trough, producing yellow-spotted tobacco and affecting the quality of the tobacco. Therefore, the pipes need to be cleaned regularly.

[0003] In related technologies, the inside of pipes is usually cleaned by operators using high-pressure water guns. However, the wastewater generated during this cleaning process will fall directly from the pipe opening onto the floor of the production workshop, affecting the environment of the production workshop and making subsequent cleaning a heavy burden. Summary of the Invention

[0004] One object of the present invention is to provide a cleaning device for pipes in a tobacco production workshop, which can clean the inside of the pipes while recovering the wastewater generated during the cleaning process.

[0005] Another objective of this invention is to provide a method for cleaning pipes, which can use the aforementioned cleaning device to clean pipes, with minimal impact on the production workshop environment during the cleaning process and a low burden of subsequent cleaning.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Firstly, a cleaning device for pipes in a tobacco production workshop is provided, comprising:

[0008] Recycle water tanks;

[0009] A water outlet pipe, with a first water pump and a high-pressure nozzle connected to its two ends respectively. The high-pressure nozzle extends into the pipe and includes at least a first outlet and a second outlet. The first outlet faces away from the end of the water outlet pipe, and the second outlet faces the end of the water outlet pipe. Both the first and second outlets are inclined outwards.

[0010] The connecting structure includes a connecting cavity with a first connecting port, a second connecting port, and a third connecting port spaced apart. The first connecting port is slidably and sealingly fitted onto the outer periphery of the water outlet pipe by a first sealing structure. The second connecting port is provided with a second sealing structure for sealing the pipe opening connected to the pipe. The water outlet pipe can slidably pass through the second sealing structure and forms a gap with the second sealing structure. The third connecting port is connected to the recycling water tank.

[0011] As a preferred technical solution of the cleaning device for the pipes in the tobacco production workshop, the first sealing structure includes an annular portion and a plurality of elastic teeth. The plurality of elastic teeth are arranged around the central axis of the annular portion at intervals on the inner ring side of the annular portion, and the elastic teeth seal against the outer periphery of the water outlet pipe.

[0012] As a preferred technical solution for the cleaning device for the pipes in the tobacco production workshop, the cleaning device further includes a first water supply pipe and a second water supply pipe. One end of the first water supply pipe and the second water supply pipe are both connected to the end of the outlet pipe away from the high-pressure nozzle. The other end of the first water supply pipe is connected to the first water pump. The other end of the second water supply pipe extends into the inside of the recovery water tank. The recovery water tank is equipped with a second water pump, and the other end of the second water supply pipe is connected to the second water pump.

[0013] As a preferred technical solution of the cleaning device for the pipeline in the tobacco production workshop, the recycling water tank is provided with a filter baffle. The filter baffle divides the internal space of the recycling water tank into a first inner cavity and a second inner cavity located above the first inner cavity along the direction of gravity. The third connecting port is connected to the first inner cavity, and the second water pump is located in the second inner cavity.

[0014] As a preferred technical solution for the cleaning device for the pipes in the tobacco production workshop, the cleaning device further includes a tube reel, which includes a first support and a rotating shaft. The two ends of the rotating shaft are rotatably connected to the first support, and the water outlet pipe is connected to the rotating shaft.

[0015] As a preferred technical solution of the cleaning device for the pipes in the tobacco production workshop, the tube reel also includes a tube reel housing, which is disposed on the first support and covers the outer periphery of the rotating shaft and the water outlet pipe wound around the rotating shaft. The tube reel housing is provided with an inlet and outlet, and the water outlet pipe can slide through the inlet and outlet.

[0016] As a preferred technical solution for the cleaning device of the pipeline in the tobacco production workshop, the interior of the rotating shaft is at least partially hollow and at least one end of the rotating shaft is open. The outer periphery of the rotating shaft is also provided with a connection port. One end of the water outlet pipe is connected to the outer periphery of the rotating shaft and communicates with the connection port. The tube winder also includes a connecting member. At least one end of the rotating shaft is rotatably and sealingly connected to the connecting member. The interior of the connecting member is connected to the interior of the rotating shaft. The connecting member is also connected to the first water pump through a water supply pipe.

[0017] As a preferred technical solution of the cleaning device for the pipeline in the tobacco production workshop, the second sealing structure includes a transition housing and an elastic sealing element. The transition housing includes a first cylindrical part, a transition ring part and a second cylindrical part. The diameter of the first cylindrical part is smaller than the diameter of the second cylindrical part. The inner side of the transition ring part is sealed to the first cylindrical part, and the outer side of the transition ring part is sealed to the second cylindrical part.

[0018] The first cylindrical portion is connected to a plurality of fasteners, which are distributed at intervals along the circumference of the first cylindrical portion. The connecting structure is also provided with a plurality of clearance grooves corresponding to the plurality of fasteners. The clearance grooves are connected to the second connecting port. The connecting structure is partially sleeved on the outer periphery of the first cylindrical portion, and the fasteners are partially inserted through the clearance grooves and fastened to the connecting structure.

[0019] The second cylindrical section has the elastic sealing element on its inner side, which is used to seal the pipe.

[0020] As a preferred technical solution for the cleaning device for the pipeline in the tobacco production workshop, the cleaning device further includes a second support, and the connecting structure and the recycling water tank are both fixedly installed on the second support.

[0021] Secondly, a method for cleaning a pipeline is provided, which uses the cleaning device described in the foregoing technical solution to clean the pipeline, the cleaning method comprising:

[0022] The water outlet pipe is inserted into the second sealing structure, and the high-pressure nozzle is located in the connecting cavity of the connecting structure or extends into the pipe.

[0023] The second sealing structure is sealed and connected to the pipe opening of the pipe;

[0024] Start the first water pump;

[0025] After the pipeline is cleaned, the first water pump is turned off;

[0026] Pull the water outlet pipe out of the pipeline;

[0027] The second sealing structure is removed from the pipe.

[0028] The beneficial effects of this invention are as follows:

[0029] By setting up a connecting structure, the first sealing structure can be slidably and sealingly fitted onto the outer periphery of the outlet pipe, and the outlet pipe can be slidably inserted into the second sealing structure, forming a gap between them. This allows wastewater flowing out of the outlet pipe to enter the connecting cavity of the connecting structure through the gap between the outlet pipe and the second sealing structure after the second sealing structure is sealed and connected to the pipe opening. The wastewater can then flow into the recycling tank through the third connecting port. Thus, during the cleaning process of the pipe using the cleaning device provided by this invention, the connecting structure and the recycling tank can be used to simultaneously recycle the wastewater generated during the cleaning process, thereby avoiding the impact of wastewater on the production workshop environment.

[0030] Furthermore, by including a first outlet with its end facing away from the outlet pipe and inclined outwards, a high-pressure water jet from the first outlet can be sprayed onto the inner wall of the pipe to clean it. The water outlet also includes a second outlet with its end facing away from the outlet pipe and inclined outwards. This allows for further cleaning of the inner wall of the pipe by spraying high-pressure water jets from the second outlet onto it. Additionally, the water's movement along the outlet pipe's extension direction into the high-pressure nozzle and then its turning towards the second outlet creates a thrust that propels the high-pressure nozzle deeper into the pipe. Thus, the cleaning device can automatically and completely clean the inner wall of the pipe along its extension direction. Attached Figure Description

[0049] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] like Figures 1 to 3 As shown, the present invention provides a cleaning device for pipelines in a tobacco production workshop, including a water recovery tank 1, a water outlet pipe 2, and a connecting structure 3. A first water pump (not shown) and a high-pressure nozzle 20 are respectively connected to both ends of the water outlet pipe 2. The high-pressure nozzle 20 is used to extend into the pipeline (not shown). The high-pressure nozzle 20 includes at least a first water outlet (not shown) and a second water outlet (not shown). The first water outlet faces away from the end of the water outlet pipe 2, and the second water outlet faces the end of the water outlet pipe 2. Both the first and second water outlets are inclined outwards. The inclined, connecting structure 3 includes a connecting cavity 30, which has a first connecting port 31, a second connecting port 32 and a third connecting port 33 spaced apart. The first connecting port 31 is slidably and sealingly fitted to the outer periphery of the water outlet pipe 2 through a first sealing structure 310. The second connecting port 32 is provided with a second sealing structure 320, which is used to seal the pipe opening connected to the pipe. The water outlet pipe 2 can be slidably inserted through the second sealing structure 320 and forms a gap with the second sealing structure 320. The third connecting port 33 is connected to the recycling water tank 1.

[0053] By setting the connecting structure 3, the first sealing structure 310 is slidably and sealingly fitted onto the outer periphery of the outlet pipe 2, and the outlet pipe 2 is slidably inserted into the second sealing structure 320, forming a gap between them. After the second sealing structure 320 is sealed and connected to the pipe opening, the sewage flowing out of the pipe opening can enter the connecting cavity 30 of the connecting structure 3 through the gap between the outlet pipe 2 and the second sealing structure 320, and then flow into the recycling tank 1 through the third connecting port 33. Thus, during the cleaning process of the pipe using the cleaning device provided by this invention, the connecting structure 3 and the recycling tank 1 can be used to simultaneously recycle the sewage generated during the cleaning process, so as to avoid the sewage from affecting the environment of the production workshop.

[0054] Furthermore, by including a first outlet with its end facing away from the outlet pipe 2 and inclined outwards, the high-pressure water jet ejected from the first outlet can be sprayed onto the inner wall of the pipe to clean it. The inclusion of a second outlet with its end facing away from the outlet pipe 2 and inclined outwards allows for further cleaning of the inner wall by spraying high-pressure water jets from the second outlet onto it. Additionally, the water jet's movement along the extension direction of the outlet pipe 2 into the high-pressure nozzle 20, and then its turning towards the second outlet, creates a thrust that propels the high-pressure nozzle 20 deeper into the pipe. This allows the cleaning device to automatically and completely clean the inner wall of the pipe along its extension direction.

[0055] Please combine Figures 4 to 6 As shown, optionally, the first sealing structure 310 includes an annular portion 3101 and a plurality of elastic teeth 3102. The plurality of elastic teeth 3102 are spaced apart and arranged around the central axis of the annular portion 3101 on the inner ring side of the annular portion 3101. The elastic teeth 3102 seal against the outer periphery of the outlet pipe 2, so that the elastic teeth 3102 have a certain deformation space and can abut against the outer periphery of the outlet pipe 2. This ensures the mobility of the outlet pipe 2 relative to the first sealing structure 310 while making the sealing connection between the first sealing structure 310 and the outer periphery of the outlet pipe 2 better, thereby reducing the possibility of the recovered sewage leaking from the connection between the first sealing structure 310 and the outlet pipe 2. Figures 3 to 6 The cross-sectional lines are omitted in the text.

[0056] Optionally, the cleaning device also includes a first water supply pipe 4, one end of which is connected to the end of the outlet pipe 2 away from the high-pressure nozzle 20, and the other end of which is connected to a first water pump, so that the first water pump can supply water to the outlet pipe 2 through the first water supply pipe 4.

[0057] Optionally, the cleaning device also includes a second water supply pipe 5. One end of the second water supply pipe 5 is connected to the end of the outlet pipe 2 away from the high-pressure nozzle 20, and the other end of the second water supply pipe 5 extends into the inside of the recovery water tank 1. The recovery water tank 1 is equipped with a second water pump (not shown in the figure), and the other end of the second water supply pipe 5 is connected to the second water pump. Thus, the second water pump and the second water supply pipe 5 can be used to supply water to the outlet pipe 2 using the recovered wastewater, effectively reducing the water consumption of the cleaning device.

[0058] Optionally, the recycling tank 1 is equipped with a filter baffle 10, which divides the internal space of the recycling tank 1 into a first inner cavity 11 and a second inner cavity 12 located above the first inner cavity 11 along the direction of gravity G. A third connecting port 33 connects to the first inner cavity 11, and a second water pump is located in the second inner cavity 12. This allows large particles of impurities to be filtered through the filter baffle 10, retaining them in the first inner cavity 11. When the water in the second inner cavity 12 is supplied to the outlet pipe 2 for cleaning via the second water pump and the second water supply pipe 5, blockage of the water pipes and conduits due to excessive wastewater impurities in the second inner cavity 12 can be avoided. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The arrow in the diagram indicates the direction of gravity G when the cleaning device is in its operating posture.

[0059] Optionally, the cleaning device also includes a hose reel 6, which includes a first support 61 and a rotating shaft (not shown in the figure). Both ends of the rotating shaft are rotatably connected to the first support 61, and the water outlet pipe 2 is partially connected to the rotating shaft. Thus, when cleaning the pipe using the cleaning device, the thrust generated by the water flow at the high-pressure nozzle 20 can be used to pull the water outlet pipe 2 to unwind onto the rotating shaft. After cleaning the pipe using the cleaning device, the water outlet pipe 2 can be pulled out of the pipe and wound up by rotating the rotating shaft.

[0060] Optionally, a rotating motor connected to the rotating shaft can be installed on the first bracket 61 so that the rotating shaft can be driven to rotate by the rotating motor to realize the automatic winding of the water outlet pipe 2. Alternatively, a handle can be installed on the rotating shaft so that the rotating shaft can be driven to rotate by manually turning the handle to realize the winding of the water outlet pipe 2.

[0061] Optionally, the hose reel 6 also includes a hose reel housing 62, which is disposed on the first bracket 61 and covers the outer periphery of the rotating shaft and the water outlet pipe 2 wound around the rotating shaft. The hose reel housing 62 is provided with an inlet 620, through which the water outlet pipe 2 can slide. This allows the hose reel housing 62 to cover the water outlet pipe 2 wound around the rotating shaft, thus preventing the operator from touching the rotating water outlet pipe 2 or the rotating shaft and getting injured during the rotation of the rotating shaft to unwind or wind up the water outlet pipe 2, thereby improving the safety of the cleaning device.

[0062] Please combine Figure 7 As shown, at this time, optionally, the rotating shaft is rotatably connected to the tube housing 62; in other words, the rotating shaft can be rotatably connected to the first bracket 61 through the tube housing 62.

[0063] Optionally, the rotating shaft is at least partially hollow inside and open at least one end. A connection port is also provided on the outer periphery of the rotating shaft. One end of the outlet pipe 2 is connected to the outer periphery of the rotating shaft and communicates with the connection port. The hose reel 6 also...

[0064] The device includes a connecting member 63, which is rotatably and sealingly connected to at least one end of the rotating shaft. The interior of the connecting member 63 is connected to the interior of the rotating shaft. The connecting member 63 is also connected to the first water pump via a water supply pipe, thereby ensuring a stable connection between the outlet pipe 2 and the water supply pipe when the rotating shaft rotates relative to the first support 61. The connecting member 63 is rotatably and sealingly connected to the outlet pipe 2 via a bearing.

[0065] When the cleaning device includes a first water supply pipe 4 and a second water supply pipe 5 as described in the aforementioned technical solution, in an optional technical solution, both opposite ends of the rotating shaft are rotatably and sealed with a connecting member 63, and the first water supply pipe 4 and the second water supply pipe 5 are respectively connected to the two connecting members 63 located at the two opposite ends of the rotating shaft, so that both the first water supply pipe 4 and the second water supply pipe 5 are connected to the outlet pipe 2.

[0066] In another alternative technical solution, one end of the rotating shaft is rotatably and sealingly connected to a connecting member 63. The connecting member 63 is a three-way connecting member 63. The first water supply pipe 4 and the second water supply pipe 5 are both connected to the connecting member 63 so that the first water supply pipe 4 and the second water supply pipe 5 are both connected to the outlet pipe 2.

[0067] Optionally, the second sealing structure 320 includes a transition housing 3201 and an elastic seal 3202. The transition housing 3201 includes a first cylindrical portion 3201a, a transition ring portion 3201b, and a second cylindrical portion 3201c. The diameter of the first cylindrical portion 3201a is smaller than the diameter of the second cylindrical portion 3201c. The inner side of the transition ring portion 3201b is sealed to the first cylindrical portion 3201a, and the outer side of the transition ring portion 3201b is sealed to the second cylindrical portion 3201c. The first cylindrical portion 3201a is connected to a plurality of fasteners 3201d, which are spaced apart circumferentially along the first cylindrical portion 3201a. The connecting structure 3 also corresponds to a plurality of fasteners 3201d. 01d is provided with multiple clearance grooves 321, which are connected to the second connecting port 32. The connecting structure 3 is partially sleeved on the outer periphery of the first cylindrical part 3201a. The fastener 3201d is partially inserted through the clearance groove 321 and is fastened to the connecting structure 3. Thus, the first cylindrical part 3201a can be fastened to the connecting structure 3 by the fastener 3201d, while the second connecting port 32 is connected to the interior of the adapter housing 3201. Since the connecting structure 3 is partially sleeved on the outer periphery of the first cylindrical part 3201a, when sewage flows back from the first cylindrical part 3201a to the connecting structure 3, it is not easy for leakage to occur at the connection between the connecting structure 3 and the first cylindrical part 3201a.

[0068] Specifically, the fastener 3201d may include a stud fixed to the first cylindrical portion 3201a and a nut threaded to the stud, thereby enabling the first cylindrical portion 3201a to be fastened to the connecting structure 3 by passing the stud through the relief groove 321 and tightening the nut to clamp together with the outer periphery of the first cylindrical portion 3201a to the connecting structure 3.

[0069] Optionally, the inner side of the second cylindrical part 3201c is provided with an elastic sealing element 3202, which is used to seal the sleeve to the pipe, thereby enabling the connection between the second cylindrical part 3201c and the pipe to have a better sealing performance.

[0070] Please combine Figure 8 As shown, optionally, the third connection port 33 can be connected to the recycling water tank 1 through the recycling pipe 7, thereby making the relative position of the connection structure 3 and the recycling water tank 1 more selective and allowing for more flexible configuration of the connection structure 3 and the recycling water tank 1.

[0071] Optionally, the cleaning device also includes a second support 8, and the connecting structure 3 and the recycling water tank 1 are all fixedly installed on the second support 8, so that the connecting structure 3, the first support 61 and the recycling water tank 1 can be connected into one unit through the second support 8, so that the relative positions of the connecting structure 3, the first support 61 and the recycling water tank 1 are more stable, thereby making the cleaning function of the cleaning device more stable.

[0072] When the cleaning device further includes a hose reel 6 as described in the aforementioned technical solution, the first bracket 61 is also fixedly mounted on the second bracket 8.

[0073] Optionally, the second support 8 can be mounted on an external support, or the bottom of the second support 8 can be equipped with rollers to facilitate the overall movement of the cleaning device. When the cleaning device further includes a recovery pipe 7 as described in the aforementioned technical solution, the recovery pipe 7 can be wound around the second support 8 to make the posture of the recovery pipe 7 more stable, thereby making the function of recovering wastewater from the third connecting port 33 through the recovery pipe 7 more stable.

[0074] This invention also provides a method for cleaning pipes, using the cleaning device described in the foregoing technical solutions to clean the pipes; please refer to [the foregoing technical solutions] as well. Figures 1 to 3 Cleaning methods include:

[0075] S1. The water outlet pipe 2 is inserted into the second sealing structure 320, and the high-pressure nozzle 20 is located in the connecting cavity 30 of the connecting structure 3 or extends into the pipe.

[0076] S2. The second sealing structure 320 is sealed and connected to the pipe opening.

[0077] S3. Start the first water pump.

[0078] This allows water to be sprayed out through the outlet pipe 2 and the high-pressure nozzle 20, thereby automatically cleaning the pipe.

[0079] Optionally, when the cleaning device further includes a second water pump, step S3 may include:

[0080] S30, start the first water pump and the second water pump.

[0081] S4. After the pipeline is cleaned, turn off the first water pump.

[0082] Optionally, when the cleaning device further includes a second water pump, step S4 may include:

[0083] S40. After the pipeline cleaning is completed, turn off the first water pump and the second water pump.

[0084] S5. Pull out water outlet pipe 2 from the pipeline.

[0085] When the cleaning device includes a hose reel 6, the rotating shaft can be rotated manually or by a motor to reel in the water outlet pipe 2, while simultaneously pulling the water outlet pipe 2 out of the pipe.

[0086] S6. Remove the second sealing structure 320 from the pipeline.

[0087] The cleaning device described in the aforementioned technical solution is easy to operate for cleaning pipelines, and the cleaning process has little impact on the production workshop environment, resulting in a small cleaning burden in the later stages.
