Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and particularly relates to a cleaning device and a cleaning method for pipelines in a cut tobacco production workshop. Background Art

[0002] During the tobacco leaf processing production process, the high-temperature and high-humidity gas discharged from the pipeline towards the cut tobacco production workshop will carry tobacco soil. Therefore, after a period of production, tobacco mud will accumulate in the pipeline, which will affect the exhaust efficiency of the pipeline and may even flow back to the outlet vibrating trough, resulting in yellow-spotted tobacco and affecting the quality of cut tobacco. Therefore, the pipeline needs to be cleaned regularly.

[0003] In the related art, the inside of the pipeline is usually cleaned by an operator operating a high-pressure water gun. However, the sewage generated during the cleaning process will directly fall from the pipeline opening of the pipeline to the ground of the production workshop, affecting the environment of the production workshop and resulting in a heavy subsequent cleaning burden.

[0049] To make the technical problems solved by the present invention, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0050] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0051] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0052] As Figures 1 to 3 shown, the present invention provides a cleaning device for the pipes in a cut tobacco production workshop, including a recovery water tank 1, a water outlet pipe 2, and a connection structure 3. Both ends of the water outlet pipe 2 are respectively connected to a first water pump (not shown in the figure) and a high-pressure nozzle 20. The high-pressure nozzle 20 is used to extend into the pipe (not shown in the figure). The high-pressure nozzle 20 at least includes a first water outlet (not shown in the figure) and a second water outlet (not shown in the figure). 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 water outlet and the second water outlet are inclined towards the outer periphery. The connection structure 3 includes a connection cavity 30. The connection cavity 30 has spaced first connection port 31, second connection port 32, and third connection port 33. The first connection port 31 is slidably and sealingly sleeved on the outer periphery of the water outlet pipe 2 through a first sealing structure 310. The second connection port 32 is provided with a second sealing structure 320. The second sealing structure 320 is used for sealing connection to the pipe opening of the pipe. The water outlet pipe 2 can slidably pass through the second sealing structure 320 and form a gap with the second sealing structure 320. The third connection port 33 communicates with the recovery water tank 1.

[0053] By setting up the communication structure 3, the first sealing structure 310 can be slidably and sealingly sleeved on the outer periphery of the water outlet pipe 2, and the water outlet pipe 2 can be slidably passed through the second sealing structure 320 and form a gap with the second sealing structure 320. After the second sealing structure 320 is sealingly connected to the pipe orifice of the pipeline, the sewage flowing out of the pipe orifice of the pipeline can enter the communication cavity 30 of the communication structure 3 through the gap between the water outlet pipe 2 and the second sealing structure 320, and can flow into the recovery water tank 1 through the third communication port 33. Thus, during the process of cleaning the pipeline by using the cleaning device provided by the present invention, the communication structure 3 and the recovery water tank 1 can be used to synchronously recover the sewage generated during the cleaning process, so as to avoid the sewage from affecting the environment of the production workshop.

[0054] In addition, by making the water outlet pipe 2 include a first water outlet that is opposite to the end of the water outlet pipe 2 and inclined toward the outer periphery, the high-pressure water flow ejected from the first water outlet can be used to spray toward the inner wall of the pipeline to clean the inner wall of the pipeline. And by making the water outlet pipe 2 include a second water outlet that is toward the end of the water outlet pipe 2 and inclined toward the outer periphery, on the one hand, the high-pressure water flow ejected from the second water outlet can be used to spray toward the inner wall of the pipeline to further clean the inner wall of the pipeline. On the other hand, when the water flows along the extension direction of the water outlet pipe 2 into the high-pressure nozzle 20 and then turns to flow out toward the second water outlet, the thrust generated along the extension direction of the water outlet pipe 2 on the high-pressure nozzle 20 can be utilized to push the high-pressure nozzle 20 to penetrate deep into the pipeline. Thus, the cleaning device can be used to automatically clean the inner wall of the pipeline completely along the extension direction of the pipeline.

[0055] Please refer to 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 arranged at intervals around the central axis of the annular portion 3101 on the inner ring side of the annular portion 3101. The elastic teeth 3102 are sealingly abutted against the outer periphery of the water outlet pipe 2. Thus, the elastic teeth 3102 have a certain deformation space and can abut against the outer periphery of the water outlet pipe 2. While ensuring the mobility of the water outlet pipe 2 relative to the first sealing structure 310, the sealing connection effect between the first sealing structure 310 and the outer periphery of the water outlet pipe 2 is better, so as to reduce the possibility of the recovered sewage leaking from the connection between the first sealing structure 310 and the water outlet pipe 2. Among them, Figures 3 to 6 The sectional lines are omitted in the figure.

[0056] Optionally, the cleaning device further includes a first water supply pipe 4. One end of the first water supply pipe 4 is connected to the end of the water outlet pipe 2 far from the high-pressure nozzle 20, and the other end of the first water supply pipe 4 is connected to the first water pump. Thus, the first water pump can supply water to the water outlet pipe 2 through the first water supply pipe 4.

[0057] Optionally, the cleaning device further includes a second water supply pipe 5. One end of the second water supply pipe 5 is also connected to the end of the water 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. A second water pump (not shown in the figure) is provided in the recovery water tank 1, 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 water outlet pipe 2 with the recycled wastewater, effectively reducing the water consumption of the cleaning device.

[0058] Optionally, a filter partition 10 is provided in the recovery water tank 1. The filter partition 10 divides the internal space of the recovery water tank 1 into a first inner cavity 11 and a second inner cavity 12 located above the first inner cavity 11 along the gravity direction G. The third communication port 33 communicates with the first inner cavity 11, and the second water pump is provided in the second inner cavity 12. Large-particle impurities can be filtered through the filter partition 10, so that the large-particle impurities are retained in the first inner cavity 11. When the water in the second inner cavity 12 is supplied to the water outlet pipe 2 for cleaning through the second water pump and the second water supply pipe 5, the situation of pipe blockage caused by too many sewage impurities recovered in the second inner cavity 12 can be avoided. As Figure 3 shown in Figure 4 Figure 3 shown in Figure 4 the arrow in shows the gravity direction G in the use posture of the cleaning device.

[0059] Optionally, the cleaning device further includes a hose reel 6. The hose reel 6 includes a first bracket 61 and a rotating shaft (not shown in the figure). Both ends of the rotating shaft are rotatably connected to the first bracket 61, and a part of the water outlet pipe 2 is connected to the rotating shaft. Thus, when using the cleaning device to clean the pipeline, 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 on the rotating shaft. After using the cleaning device to finish cleaning the pipeline, the water outlet pipe 2 can also be pulled out of the pipeline and wound up by winding the rotating shaft.

[0060] Optionally, a rotating motor connected to the rotating shaft can be provided on the first bracket 61 to drive the rotating shaft to rotate through the rotating motor, so as to realize the automatic winding of the water outlet pipe 2. Or, a handle can be provided on the rotating shaft to drive the rotating shaft to rotate manually through the handle, so as to realize the winding of the water outlet pipe 2.

[0061] ​Optionally, the hose reel 6 further includes a hose housing 62. The hose housing 62 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 housing 62 is provided with an inlet / outlet 620, and the water outlet pipe 2 can slidably pass through the inlet / outlet 620, so that the water outlet pipe 2 wound around the rotating shaft can be covered by the hose housing 62, avoiding the situation that the operator touches the rotating water outlet pipe 2 or the rotating shaft and gets injured during the process of the rotating shaft rotating to unwind or wind up the water outlet pipe 2, and improving the safety of using the cleaning device.

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

[0063] Optionally, at least part of the inside of the rotating shaft is hollow and at least one end of the rotating shaft is open. A connection port is further provided on the outer periphery of the rotating shaft. One end of the water 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] includes a connecting member 63. At least one end of the rotating shaft is rotatably and sealingly connected to the connecting member 63. The inside of the connecting member 63 communicates with the inside of the rotating shaft. The connecting member 63 is also connected to the first water pump through a water supply pipe, so that when the rotating shaft rotates relative to the first bracket 61, the communication state between the water outlet pipe 2 and the water supply pipe can be stabilized. Wherein, the connecting member 63 can be rotatably and sealingly connected to the water outlet pipe 2 through a bearing.

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

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

[0067] Optionally, the second sealing structure 320 includes an adapter housing 3201 and an elastic seal 3202. The adapter 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 that of the second cylindrical portion 3201c. The inner side of the transition ring portion 3201b is sealingly connected to the first cylindrical portion 3201a, and the outer side of the transition ring portion 3201b is sealingly connected to the second cylindrical portion 3201c. A plurality of fasteners 3201d are connected to the first cylindrical portion 3201a, and the plurality of fasteners 3201d are circumferentially spaced apart along the first cylindrical portion 3201a. The communication structure 3 is also provided with a plurality of relief grooves 321 corresponding to the plurality of fasteners 3201d. The relief grooves 321 communicate with the second communication port 32. The communication structure 3 is partially sleeved on the outer periphery of the first cylindrical portion 3201a. The fasteners 3201d partially pass through the relief grooves 321 and are tightly connected to the communication structure 3, so that the first cylindrical portion 3201a can be tightly connected to the communication structure 3 through the fasteners 3201d, and at the same time, the second communication port 32 is communicated with the inside of the adapter housing 3201. Since the communication structure 3 is partially sleeved on the outer periphery of the first cylindrical portion 3201a, when sewage flows back from the first cylindrical portion 3201a to the communication structure 3, it is not easy to leak at the connection between the communication structure 3 and the first cylindrical portion 3201a.

[0068] Specifically, the fastener 3201d may include a stud fixed to the first cylindrical portion 3201a and a nut threadedly connected to the stud. By passing the stud through the relief groove 321 and tightening the nut to clamp the communication structure 3 together with the outer periphery of the first cylindrical portion 3201a, the first cylindrical portion 3201a can be tightly connected to the communication structure 3.

[0069] Optionally, an elastic seal 3202 is provided on the inner side of the second cylindrical portion 3201c. The elastic seal 3202 is used for sealingly sleeving on the pipeline, so that the connection between the second cylindrical portion 3201c and the pipeline has better sealing performance.

[0070] Please refer to Figure 8 As shown, optionally, the third communication port 33 can be connected to the recovery water tank 1 through the recovery pipe 7, so that the relative position of the communication structure 3 and the recovery water tank 1 has better selectivity, and the communication structure 3 and the recovery water tank 1 can be set more flexibly.

[0071] Optionally, the cleaning device further includes a second bracket 8. The communication structure 3 and the recovery water tank 1 are both fixedly arranged on the second bracket 8, so that the communication structure 3, the first bracket 61, and the recovery water tank 1 can be connected into a whole through the second bracket 8, so that the relative positions of the communication structure 3, the first bracket 61, and the recovery water tank 1 are relatively stable, and further the cleaning function of the cleaning device is relatively stable.

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

[0073] Optionally, the second bracket 8 can be cooperatively arranged on an external bracket, or rollers can be installed at the bottom of the second bracket 8 to facilitate the overall movement of the cleaning device. When, as described in the foregoing technical solution, the cleaning device further includes a recovery pipe 7, the recovery pipe 7 can be wound around the second bracket 8 to make the posture of the recovery pipe 7 more stable, and further make the function of recovering sewage from the third communication port 33 to the recovery water tank 1 through the recovery pipe 7 more stable.

[0074] The present invention also provides a method for cleaning a pipeline, using the cleaning device as described in the foregoing technical solution to clean the pipeline. Please also refer to Figures 1 to 3 , and the cleaning method includes:

[0080] S30. Start the first water pump and the second water pump.

[0081] S4. After the pipeline cleaning is completed, 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.
