Description

Technical Field

[0001] The invention relates to the technical field of filtering and cleaning devices, and in particular to an online pipeline filtering and cleaning device. Background Art

[0002] As we all know, pipelines are one of the equipment for material transportation and are very commonly used in actual production. As the pipeline is used for a long time, it is inevitable that the corresponding transported materials will adhere to the pipeline. If the adhered transported materials accumulate, it will inevitably affect the normal transportation operation of the pipeline. The pipeline online filtering and cleaning device is an auxiliary equipment that can filter the transported materials and clean the inner wall of the conveying pipeline, aiming to keep the pipeline system clean and efficient.

[0003] After searching, the Chinese patent publication number CN220461629U discloses a filter pipe cleaning device for exhaust gas purification, which is roughly described as comprising a support frame, a fixed block is fixedly connected to the upper end of the support frame, a rotating assembly for driving the pipe to rotate is arranged on the outer side of the fixed block, a connecting block is fixedly connected to the right end of the rotating assembly, an adjusting assembly for adjusting the position is arranged on the upper end of the connecting block, a cleaning assembly for brushing is arranged inside the adjusting assembly, and a flushing assembly for flushing is arranged inside the adjusting assembly. When in use, flushing water is added to the spliced ​​pipe through the water inlet pipe, and sprayed into the pipe under the action of the through hole to flush the inside, and then the double-axis motor is turned on to drive the rotating shaft and the driven shaft to rotate at the same time, so that the cleaning brushes on the outside of the two sets of rotating rods brush the inside and outside of the tank wall, and finally the driving motor is started. Drive the pipeline to rotate slowly to achieve cleaning around the pipe wall. The Chinese patent announcement number CN104984946A discloses an automatic cleaning device for the filter element of an oil pipeline filter, which is roughly described as including a box body and a pull-out rotating support mechanism. A steam manifold is fixedly installed in the box body, and a plurality of nozzles are symmetrically installed on the steam manifold in a centripetal manner. The box body is connected to the boiler car through a quick connector, and a filter element is movably mounted on the pull-out rotatable support mechanism installed in the middle of the box body. A box door is installed at the front of the box body, an exhaust chimney is installed on the top, and an oil collection tray is movably mounted on the bottom.

When in use, steam is sprayed through the nozzles at the rear and on the left and right sides to flush the filter element.

For some fixed-installed pipelines with long material transportation distances, it is difficult to form corresponding movement due to the cumbersome laying and difficult disassembly.

Through the configuration of the mounting assembly,The carrier structure formed by the fixed electromagnet 13, the movable electromagnet 14 and the movable servo motor 15 can form a corresponding moving operation relative to the pipeline laid on the surface, so as to facilitate the relative movement and dragging of the cleaning component inside the pipeline, thereby achieving the cleaning operation of the pipeline where the pipeline is located.

[0037] The movable servo motor 15, the driving servo motor 19, the conductor column 35 and the conductor wire 36 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. Other models can also be selected or customized according to actual needs. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0038] In summary, the working process of the pipeline online filtering and cleaning device is as follows: when in use, firstly, the cleaning component is installed relative to the inside of the pipeline. The cleaning component can be installed through the Y-type filter during later maintenance, or can be preset inside the pipeline at the beginning of pipeline laying and installation. Under the influence of the magnetic field between the fixed position electromagnet 13 and the movable position electromagnet 14 and the permanent magnet 11, the two reset springs 12 respectively pull the multi-directional moving rod 8 and the unidirectional moving rod 9, so that the multi-directional moving rod 8 and the unidirectional moving rod 9 are respectively inserted into the moving frame 2 and the inner frame 2. The one-way moving rod 9 is inserted into the inner island frame 1, and the driving rack 32 is driven to move synchronously during the relative insertion process with respect to the inner island frame 1. The installation shaft 31 can be driven to rotate under the meshing transmission action of the driving rack 32 and the driving gear 33. The rotation of the installation shaft 31 drives the transmission gear 30 to rotate. The rotation of the transmission gear 30 drives the two linked racks 29 to move synchronously. The synchronous movement of the two linked racks 29 can realize the synchronous relative movement away from the two symmetrical support rods 28, that is, the two symmetrical support rods 28 will form a tight state relative to the inner wall of the pipe. In order to achieve the relative positioning of the internal island frame 1 in the pipeline, and finally achieve the stability of the relative position of the cleaning component in the pipeline, the extended brush member 5 in the cleaning component is matched with the bifurcated bristles 43 to form a covering arrangement in the pipeline, forming a filtering functional component inside the pipeline, placing the mounting component on the pipeline, and driving the servo motor 19 to power on to realize the rotation drive of the bidirectional gradient roller 18, so that the mounting component can form a relative active displacement on the pipeline. When the mounting component moves to the area where the cleaning component is located, the power supply of the two conductor wires 36 is turned on, so that the two conductor wires 36 are connected to the two conductor wires 36. Each conductor wire 36 is matched with two conductor columns 35 to form an electromagnetic field, so that the two electromagnetic fields form magnetic capture on the two permanent magnets 11 respectively. After the two electromagnetic fields form magnetic capture with the two permanent magnets 11 respectively, the current passed through the two conductor wires 36 is appropriately increased to increase the magnetic field strength of the electromagnetic field, so as to prompt the multi-directional movable rod 8 and the unidirectional movable rod 9 to be respectively withdrawn from the movable frame 2 and the internal island frame 1, so that the relative distance between the fixed position electromagnet 13 and the movable position electromagnet 14 and the two permanent magnets 11 is closer, and the mutual magnetic force is greater.

[0039] Furthermore, when the one-way movable rod 9 is partially pulled out relative to the internal island frame 1, the two symmetrical support rods 28 are synchronously moved closer to each other under the sequential transmission of the driving rack 32, the driving gear 33, the mounting shaft 31 and the transmission gear 30. After that, the tightening and positioning effect formed by the two symmetrical support rods 28 in the pipeline fails. In this state, the fixed position electromagnet 13 will form a synchronous displacement with the mounting component. Under the mutual magnetic attraction between the fixed position electromagnet 13 and the permanent magnet 11 on the one-way movable rod 9, the cleaning component will follow the movement of the mounting component to form a follow-up movement, and the extended brush 5 and The bifurcated bristles 43 will move relative to the inner wall of the pipe to assist in cleaning the inner wall of the pipe, and the active servo motor 15 will realize the rotation drive of the circular plate 20 after being powered on. The transmission column 21 and the strip groove 22 on the circular plate 20 will drive the rotating circular plate 20 to realize the reciprocating sliding movement of the active position electromagnet 14 relative to the corresponding middle hanger 17 installed thereon. The reciprocating movement of the active position electromagnet 14 will realize the spatial position change of the electromagnetic field generated by the cooperation of the conductor column 35 and the conductor wire 36 therein, and the change of the electromagnetic field will realize the single-direction movement through the permanent magnet 11 on the multi-directional moving rod 8. The relative position of the moving rod 9 changes along the center line of the pipeline, and finally the reciprocating sliding movement of the moving frame 2 relative to the internal island frame 1 is realized, and the movement of the moving frame 2 will drive the synchronous movement of the linkage shaft 7. Under the transmission action of the linkage shaft 7 and the spiral strip mouth 6, the movement of the linkage shaft 7 will realize the rotation movement of the rotating sleeve 4 relative to the recessed ring groove 3. The reciprocating rotation movement of the rotating sleeve 4 will drive the extended brush member 5 thereon to form a relative rotation drive relative to the inner wall of the pipeline, further improving the cleaning effect of the inner wall of the pipeline, and finally achieving the cleaning operation in the pipeline. The cleaning operation does not require the disassembly of the pipeline, and when the pipeline is outside due to various When the stirrups and auxiliary positioning structures prevent the bidirectional gradient roller 18 from passing through, it is only necessary to control the electric telescopic rod 24 to work and control the end hanger 16 to be lifted relative to the middle hanger 17, so that the end hanger 16 can cross over the structures outside the pipeline such as the stirrups and auxiliary positioning. The passage of the middle hanger 17 requires the two electric telescopic rods 24 to work synchronously with the two driving servo motors 19 on the front and rear sides, so that the two middle hangers 17 located between the two end hangers 16 form an arched posture, so as to facilitate the lifting of the bidirectional gradient roller 18 installed in the two middle hangers 17, and finally facilitate the crossing over the obstacles on the pipeline.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
