The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figure 1 , in a specific embodiment of the present application, an all-round and dead-angle-free tower cleaning system is used to clean the tower. The inner wall includes a flushing pipe 100, a telescopic sleeve 200 and a rotating spray head assembly 300. The water inlet of the flushing pipe 100 is connected with a flushing pump 400, and the water outlet of the flushing pipe 100 vertically extends into the tower. The telescopic sleeve 200 includes a lifting inner pipe 210 and a driving outer pipe 220. The lifting inner pipe 210 is sleeved on the outer wall of the flushing pipe 100 and can slide up and down along the axial direction of the flushing pipe 100. The water outlet of the lifting inner pipe 210 is lower than the water outlet of the flushing pipe 100, and a rotating spray head assembly 300 is rotatably arranged at the water outlet of the lifting inner pipe 210. The driving outer pipe 220 is rotatably arranged on the tower, and the driving outer pipe 220 is sleeved on the outer wall of the lifting inner pipe 210, and the inner wall of the driving outer pipe 220 is in threaded transmission cooperation with the outer wall of the lifting inner pipe 210.

[0024] The all-round and dead-angle-free tower cleaning system of the present application can be used to clean various towers, especially the main tower of large stainless steel towers, spray drying towers, large tanks, silos, etc. When working, start the flushing pump 400 to convey the cleaning liquid to the flushing pipe 100. According to the actual working conditions, alkali cleaning, acid cleaning or water cleaning, etc. can be used. The cleaning liquid flows into the lifting inner pipe 210 through the flushing pipe 100, and then is sprayed onto the inner wall of the tower through the rotating nozzle assembly 300 located at the water outlet of the lifting inner pipe 210 for cleaning. At the same time, rotate the driving outer pipe 220. Since the driving outer pipe 220 and the lifting inner pipe 210 are in threaded transmission cooperation, in this solution, it is a transmission thread, and the tooth profile includes but is not limited to trapezoidal, rectangular, saw-tooth and triangular, etc. Therefore, under the rotation of the driving outer pipe 220, the lifting inner pipe 210 slides up and down along the axis of the flushing pipe 100, and the rotating nozzle assembly 300 makes a reciprocating up and down movement while rotating and cleaning the inner wall of the tower. In this way, it is possible to adjust the height of the rotating nozzle assembly 300 while cleaning the inner wall of the tower, clean the inner wall of the tower at different heights, improve the cleaning efficiency, and the cleaning is thorough and without dead angles.

[0025] Since the rotation of the driving outer pipe 220 requires external force to drive, the tower cleaning system further includes a driving mechanism 500. The driving mechanism 500 is arranged at the top of the tower and is drivingly connected to the driving outer pipe 220. The driving mechanism 500 includes an engine and a connecting component. The engine can be selected according to the actual situation, such as an electric motor, a diesel engine, etc. The connecting component is used to connect the engine and the driving outer pipe 220 so that the driving outer pipe 220 rotates under the drive of the engine. The connecting component can be selected and is not limited to a pulley, a gearbox, etc.

[0026] During the up and down sliding process of the lifting inner pipe 210, in order to prevent the lifting inner pipe 210 from having too long a stroke and colliding with the tower bottom / tower top, or having too short a stroke resulting in incomplete cleaning, position sensing devices 230 are respectively arranged at both ends of the lifting inner pipe 210, and a position triggering device 240 is arranged at the water outlet of the flushing pipe 100. The position sensing device 230 triggers and cooperates when it faces the position triggering device 240, and the position sensing device 230 is electrically connected to the driving mechanism 500. Specifically, please refer to Figure 4, a first position sensing device 231 is provided at the upper end of the inner tube, and a second position sensing device 232 is provided at the lower end. A position triggering device 240 is provided at the water outlet of the flushing tube 100. When the lifting inner tube 210 moves downward to a position where the first position sensing device 231 faces the position triggering device 240, the first position sensing device 231 is triggered, and the downward movement stops. At the same time, the engine reverses, driving the lifting inner tube 210 to start moving upward. When it moves upward to a position where the second position sensing device 232 faces the position triggering device 240, the second position sensing device 232 is triggered and the upward movement stops. At the same time, the engine reverses again, driving the lifting inner tube 210 to start moving downward. The positions of the first position sensing device 231 and the second position sensing device 232 are both adjustable, so as to realize the automatic up and down movement of the lifting inner tube 210 within a certain stroke range. Considering the simplicity of operation and convenience of installation, the position sensing device 230 is preferably a magnetic induction sensor, and the position triggering device 240 is preferably a magnet.

[0027] In a specific embodiment of the present application, the rotating nozzle assembly 300 includes a base 310 and two driving nozzles 320. The base 310 is rotatably provided at the water outlet of the lifting inner tube 210. The spraying direction of any one of the driving nozzles 320 forms an angle of 20° to 80° with the horizontal plane. The two driving nozzles 320 are symmetrically arranged on both sides of the base 310 with the lifting inner tube 210 as the axis of symmetry, and the spraying directions of the two driving nozzles 320 are opposite.

[0028] Specifically, when the flushing liquid is transported to the two driving nozzles 320 through the flushing tube 100 and the lifting inner tube 210, because the spraying direction of each driving nozzle 320 forms an angle of 20° to 80° with the horizontal plane, the two driving nozzles 320 are symmetrically arranged on both sides of the base 310 with the lifting inner tube 210 as the axis of symmetry and their spraying directions are opposite, so under the action of the high-pressure cleaning liquid spraying force, the rotating nozzle assembly 300 will start to rotate horizontally at the same time. The driving nozzle 320 can not only drive the rotating nozzle assembly 300 to rotate horizontally, but also the cleaning liquid sprayed by it has a greater pressure, which can clean some hard and firm dirt on the wall. The higher the pressure at the outlet of the cleaning pump, the faster the rotating speed of the rotating nozzle assembly 300, and the greater the pressure of the sprayed liquid, the better the cleaning effect. The nozzle assembly is preferably a high-pressure rotating nozzle.

[0029] In a preferred embodiment, the base 310 includes a horizontal cross-tube 311 and two vertical tubes 312 respectively located at both ends of the horizontal cross-tube 311. The horizontal cross-tube 311 and the two vertical tubes 312 are in an "I" shape. The midpoint of the horizontal cross-tube 311 is communicated with the water outlet of the lifting inner tube 210. Flushing nozzles 330 are provided at the outlets of the two vertical tubes 312. As described above, under the action of the high-pressure cleaning liquid jet force, the two driving nozzles 320 will simultaneously drive the nozzle assembly to start horizontal rotation, that is, drive the horizontal cross-tube 311 to start horizontal rotation around the lifting inner tube 210. At the same time, the cleaning liquid is sprayed out through the flushing nozzles 330 at the vertical tubes 312 to clean the tower wall. In order to achieve a larger cleaning range, the flushing nozzles 330 can maintain a certain angle with the horizontal plane, which can be adjusted according to the actual situation and is not specifically limited here. In another specific embodiment of the present application, please refer to Figure 2 , for the above-mentioned all-round and dead-angle-free tower body cleaning system, one end of the driving outer tube 220 extends out of the top of the tower body; the other end of the driving outer tube 220 extends into the tower body, and the driving outer tube 220 is sleeved on the outer wall of the lifting inner tube 210, and the inner wall of the driving outer tube 220 and the outer wall of the lifting inner tube 210 are in threaded transmission cooperation.

[0030] The driving outer tube 220 is used to cooperate with the driving mechanism 500 to drive the lifting inner tube 210 to perform reciprocating up and down movements, so as to achieve cleaning of each height of the inner wall of the tower during the flushing process. One end of the driving outer tube 220 extends out of the top of the tower body and is connected to the driving mechanism 500 arranged on the top of the tower, and the other end extends into the tower body and is in threaded transmission cooperation with the lifting inner tube 210. In this way, the lifting inner tube 210 does not need to extend out of the top of the tower, and relies on the part inside the tower to be in threaded transmission with the driving outer tube 220, which reduces the consumption of the lifting inner tube 210 to a certain extent.

[0031] In another specific embodiment of the present application, please refer to Figure 3 , for the above-mentioned all-round and dead-angle-free tower body cleaning system, the driving outer tube 220 is rotatably arranged at the top of the tower body, and the driving outer tube 220 is sleeved on the outer wall of the lifting inner tube 210, and the inner wall of the driving outer tube 220 and the outer wall of the lifting inner tube 210 are in threaded transmission cooperation. In this embodiment, the driving outer tube 220 only needs to be arranged at the top of the tower body and does not need to extend into the tower interior. At the same time, the top end of the lifting inner tube 210 needs to extend out of the top of the tower to be in threaded transmission cooperation with the driving outer tube 220 to realize the up and down movement of the lifting inner tube 210. The advantage of this method is that there are only the flushing tube 100 and the lifting sleeve in the tower body, and the structure is relatively simple.

[0032] The specific working process of the all-round and dead-angle-free tower body cleaning system of the present application is as follows:

[0033] During operation, the flushing pump 400 is started to convey the cleaning liquid to the flushing pipe 100. The cleaning liquid pressurized by the flushing pump 400 becomes high-pressure cleaning liquid, which is sprayed into the lifting inner pipe 210 through the flushing pipe 100. The rotating nozzle assembly 300 at the outlet of the lifting inner pipe 210 starts to rotate horizontally under the action of the jet force of the high-pressure cleaning liquid and sprays the high-pressure cleaning liquid onto the inner wall of the tower for cleaning. At the same time, the driving mechanism 500 is started, and the outer pipe 220 starts to rotate, while driving the lifting inner pipe 210 to slide up and down along the axial direction of the flushing pipe 100. When the lifting inner pipe 210 moves downward to a position where the first position sensing device 231 faces the position triggering device 240, the first position sensing device 231 is triggered, and the downward movement stops. At the same time, the engine reverses, driving the lifting inner pipe 210 to start moving upward. When it moves upward to a position where the second position sensing device 232 faces the position triggering device 240, the second position sensing device 232 is triggered and the upward movement stops. At the same time, the engine reverses again, driving the lifting inner pipe 210 to start moving downward. The positions of the first position sensing device 231 and the second position sensing device 232 can both be adjusted, so as to realize the automatic up and down movement of the lifting inner pipe 210 within a certain stroke range. In this way, while the rotating nozzle assembly 300 rotates and cleans the inner wall of the tower, the rotating nozzle assembly 300 moves up and down reciprocally to clean the inner wall of the tower at different heights, improving the cleaning efficiency and achieving thorough cleaning without dead corners.

[0034] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
