Description
Technical Field
The invention relates to a pipeline cleaning device suitable for pipe diameters of more than 500 mm.
Background
After the pipelines for water supply, sewage and the like are used for a long time, the inner walls of the pipelines can have pollutants such as precipitates, rusts, scale adhesion, biological membranes and the like, so that the problems of small inner diameter of the pipeline, insufficient water quantity, unsmooth water supply and increased water supply pressure are caused; in the water supply pipeline, the problems of water quality deterioration, secondary pollution and the like can be caused, and the human health is threatened, so that the inner wall of the pipeline is required to be cleaned frequently.
The existing physical cleaning method for the pipeline mainly comprises a one-way flushing method, a high-pressure jet flushing method, a mechanical pipe scraping method and an air pressure pulse cleaning method, and each method has respective defects and shortcomings. A one-way flushing method: and opening the fire hydrant at a specified position in the water supply pipe network for cleaning. The limitations are that each flushing requires a large amount of water and is not suitable for use when flushing large pipe diameter pipes because the required flow rate is difficult to achieve. High-pressure jet washing method: water is pressurized to over several hundred atmospheres by a high pressure water generator and converted into a high speed fine "water jet" by a jet device with fine pores. The limitations are complex instrument operation, high technical requirements, short cleaning distance, high water consumption and long cleaning time. Mechanical tube scraping method: the method comprises two methods, namely a mechanical pipe scraping method and an elastic pipe flushing method, and scales and rust are separated from the pipe wall by the friction and rolling sweeping action of a pipe cleaner on the pipe wall; secondly, the flushing action generated by the water in the pipeline can carry out secondary flushing on the stubborn part which is not scraped. The method has the limitations of great damage to the protective layer of the inner wall of the pipeline, long cleaning time, low cleaning efficiency and incapability of cleaning the variable-diameter and complex pipeline. Air pressure pulse cleaning method: the flow state in the pipeline is changed into turbulent flow, and a water hammer generates a larger impact effect on the growth ring of the pipe wall. The limitation is that the cleaning effect on the rust tumors is poor, and the control requirements on water pressure, air pressure and air volume are high.
Ice slurry, also known as fluidized ice, pumped ice, is a two-phase solid-liquid stream containing ice particles mixed with water. So-called ice slurry, is composed of ice particles with a diameter not exceeding 1mm, and the ice crystals are slightly rounded. In recent years, with the development of cold storage technology, ice slurry is increasingly used in ice storage air conditioners, and because it can be pumped, it starts to stand out in industrial duct cleaning. Ice slurry is used as a medium for cleaning pipelines mainly because of its good passability and the characteristic of being capable of being pumped. The traditional ice slurry cleaning technology is to send the ice slurry to the inlet of the pipeline to be cleaned, and the water pressure is used for pushing the ice slurry to move forward to clean the pipeline, and the method has the following problems for the pipeline with the pipe diameter within the range of 100-: the ice slurry is easy to float upwards in the pipeline, so that the problems of uneven pipeline cleaning, insufficient pressure on the inner wall of the pipeline and different pipeline cleaning effects of different pipe diameters are caused. For the large-diameter pipeline with the pipe diameter of more than 500mm, the required ice slurry consumption is larger during cleaning, and the defects of the traditional ice slurry cleaning technology are further enlarged when the ice slurry is pumped into the pipeline.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a pipeline cleaning device which has no ice slurry floating problem in the cleaning process and is suitable for pipelines with the pipe diameters of more than 500 mm.
The technical scheme is as follows: the invention relates to a pipeline cleaning device suitable for pipelines with pipe diameters of more than 500mm, which comprises a spray head fixed at the water outlet end of a high-pressure water pipe, wherein the spray head is rotationally connected with the high-pressure water pipe; the top end of the spray head is closed; the side wall of the spray head is uniformly provided with a plurality of cylindrical pore passages penetrating through the side wall along the circumferential direction; the axis of the pore canal and the central axis of the nozzle are obliquely arranged; each pore channel is fixedly connected with a spray pipe extending out of the pore channel, and the spray pipes are fixedly connected into a whole through an annular support; the pore canal which is obliquely arranged with the central axis of the spray head enables the spray head to rotate relative to the high-pressure water pipe when spraying high-pressure ice slurry.
The spray head comprises a connecting area and a spraying area, and the connecting area is rotationally connected with the high-pressure water pipe through a bearing; the injection area is in a shape of a circular truncated cone; the outer diameter of the injection area is gradually reduced along the advancing direction of the spray head.

So that the spray head can rotate and advance in the pipeline, the ice slurry can be sprayed out through the spray pipe connected in the pore passage, and the sediment on the inner wall of the pipeline can be uniformly cleaned.
When the axis of the pore canal forms an included angle of 45 degrees with the central axis of the spray head, the spraying direction of the ice slurry from the pore canal forms an included angle of 135 degrees with the advancing direction of the high-pressure water pipe, so that the component forces of two reaction forces which are parallel to the pipe axis and vertical to the pipe axis of the sprayed ice slurry are equal in magnitude, and the component forces vertical to the pipe axis generate a moment which enables the spray head to rotate around the pipe axis. If the included angle is less than 45 degrees, the included angle between the spraying direction of the ice slurry from the pore passage and the advancing direction of the high-pressure water pipe is larger, so that the sprayed ice slurry reaches the inner wall of the pipeline in a longer distance, the shearing force of the ice slurry is weakened, the reaction force perpendicular to the pipe shaft is smaller, the rotating torque is reduced, and the spray head cannot rotate fast enough. If the included angle is greater than 45 degrees, the included angle between the spraying direction of the ice slurry from the pore passage and the advancing direction of the high-pressure water pipe is smaller, so that the sprayed ice slurry reaches the inner wall of the pipeline in a shorter distance, the shearing force of the ice slurry is enhanced, the reaction force perpendicular to the pipe shaft is larger, the rotating torque is increased, the rotation of the spray head is accelerated, and the service life of a nut element and a bearing element which are connected with the spray head is easily shortened.
The number of the pore passages is six, and the spray head is fixedly connected with the pore passages through internal and external threads. The centers of the circles corresponding to the inner wall of the spray head are located on the same horizontal plane, the centers of the circles corresponding to the outer wall of the spray head are located on the same horizontal plane, and the six pore passages are evenly distributed on the spray head along the circumferential direction.

As shown in fig. 1 to 8, the invention is suitable for a pipeline cleaning device with a pipe diameter of more than 500mm, and comprises a spray head 5 fixed at the water outlet end of a high-pressure water pipe 10, wherein the spray head 5 is rotationally connected with the high-pressure water pipe 10; the top end of the spray head 5 is closed; the side wall of the spray head 5 is uniformly provided with a plurality of cylindrical pore canals 1 penetrating through the side wall along the circumferential direction; the axis of the pore channel 1 and the central axis of the spray head 5 form an included angle of 45 degrees, and the spraying direction of the ice slurry from the pore channel 1 and the advancing direction of the spray head 5 form an included angle of 135 degrees; each pore channel 1 is fixedly connected with a spray pipe 4 extending out of the pore channel 1, and the spray pipes 4 are fixedly connected into a whole through an annular support 23; when the high-pressure ice slurry is sprayed out, the pore passage 1 arranged at an included angle of 45 degrees with the central axis of the spray head 5 enables the spray head 5 to rotate relative to the high-pressure water pipe 10.
For pipelines with the pipe diameter of more than 500mm, the outer diameter of the spray head 5 is 300mm, the inner diameter is 280mm, and the wall thickness is 10 mm; the diameter of the pore passage 1 is 10 mm; the height of the circular truncated cone 1-4 is 45mm, and the overall height of the spray head 5 is 100 mm; the outer diameter of the spray pipe 4 is slightly smaller than 10mm, and the length is more than 100 mm. The sum of the outer diameter of the spray head 5 and the length of the spray pipe 4 extending out of the pore passage 1 is slightly smaller than the inner diameter of the pipeline. The length of the lance 4 is therefore varied based on the variation of the internal diameter of the pipe.
The spray head 5 comprises a connecting area 1-3 and a spraying area 1-4, and the connecting area 1-3 is rotatably connected with a high-pressure water pipe 10 through a bearing 7; the injection zones 1-4 are in the shape of a circular truncated cone; the outer diameters of the injection zones 1-4 decrease in sequence along the advancing direction of the spray head 5. The bearing 7 comprises a bearing outer ring 11 with external threads and a bearing inner ring 14 rotationally connected with the bearing outer ring 11, and the bearing outer ring 11 is fixedly connected with the connection region 1-3 through the internal and external threads; the bearing inner ring 14 is fixedly connected with the high-pressure water pipe 10 through the connecting shaft 8 and the variable-diameter joint 9. The bearing inner ring 14 can be directly and fixedly connected with one end of the connecting shaft 8 through internal and external threads, or the bearing inner ring 14 can be sleeved and clamped outside the connecting shaft 8, and the bearing inner ring 14 and the connecting shaft 8 are fixed through a round nut 16 and a stop washer 24. When the bearing inner ring 14 and the connecting shaft 8 are fixed by the round nut 16 and the stop washer 24, as shown in fig. 5 to 6, the bearing inner ring 14 is sleeved outside the connecting shaft 8, the connecting shaft 8 is provided with a key groove 25, the inner stop lug 18 of the stop washer 24 is clamped in from the key groove 25, so that the stop washer 24 is fixed relative to the connecting shaft 8 and the bearing 7 when the round nut 16 is screwed in place, and the outer stop lug 17 of the stop washer 24 bends into the groove 19 of the round nut 16 after the round nut 16 is screwed in place, thereby preventing the connection between the bearing inner ring 14 and the connecting shaft 8 from loosening. Thus, the purpose of fixing the bearing inner ring 14 is achieved through the matching of the stop washer 24 and the round nut 16 with the connecting shaft 8.
For pipelines with the pipe diameter of more than 500mm, the whole spray head 5 is in a hollow circular truncated cone shape with a closed top, the spray head 5 is made of carbon fiber light materials, so that the spray head cannot fall down too heavy in the advancing process, and the spray pipe 4 is made of hard plastics.

The tail end of the spray head 5 is fixed with the external thread 6 on the bearing outer ring 11 through the internal thread 2 and can rotate together, and the bearing inner ring 14 is fixed on the connecting shaft 8 through a round nut 16 and a stop washer. According to the momentum conservation principle, under the pressure of the water pump 30, the ice slurry is sprayed backwards from the spray pipe 4 at a high speed to generate friction with the pipe wall to generate a reaction force, so that the spray head 5 can be pushed to move forwards on one hand, and the pipe scale can be cleaned away from the inner wall of the pipeline through the contact of the ice slurry and the pipe scale and the cutting force generated by high-speed spraying on the other hand; the hole axis of the pore passage 1 and the central axis of the spray head 5 form an included angle of 45 degrees, so that the ice slurry is sprayed out from the spray pipe 4 and forms an included angle of 135 degrees with the advancing direction of the high-pressure water pipe 10. The design of the inclined spraying ice slurry enables the reaction force of the sprayed ice slurry to be not parallel to the pipe axis, and component forces can be generated in the direction parallel to the pipe axis and the direction perpendicular to the pipe axis, so that the moment for enabling the spray head 5 to rotate around the pipe axis is generated. The plurality of nozzles 4 simultaneously spray ice slurry, so that the nozzle 5 can rotate while advancing in the pipeline as a whole, the bearing outer ring 11 is driven to rotate, and the bearing inner ring 14 is fixed, so that the high-pressure water pipe 10 can stably advance in the pipeline without rotating.
