Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning and dredging technology, and in particular to a flushing and dredging device for long-distance pipeline transportation of coal gangue slurry. Background Technology

[0002] According to the patent document with publication number CN218079457U, the end of the high-pressure flushing pipe is connected to a straight-through and a mixing tee. By opening the valve of the hydraulic conveying device II, water is introduced into the high-pressure water inlet pipe and sprayed out from the high-pressure flushing nozzle, thereby carrying out some of the accumulated gangue particles. At the same time, the wind power booster device I is connected to the pipe through high-pressure air and the valve of the wind power booster device I is gradually opened to gradually provide the water and air jet pressure and sludge removal capacity of the high-pressure flushing nozzle. Then, the high-pressure flushing pipe continues to penetrate into the pipe under the drive of the high-pressure flushing nozzle, and the blocked and accumulated gangue particles are flushed away with the water flow. The patent document describes a method for cleaning clogged and accumulated gangue particles in pipelines. It relies solely on the water flow from high-pressure flushing nozzles to wash the gangue particles. Each flush only cleans the surface of the accumulated gangue, resulting in a small amount of gangue particles being removed with each flush. Consequently, a large amount of water and a long operating time are required to flush the accumulated gangue particles. Furthermore, the flushed gangue particles need to be carried away by the water flow from the high-pressure flushing nozzles. If a large amount of gangue particles are flushed off, it may cause the particles to accumulate again. Utility Model Content

[0003] The purpose of this invention is to provide a flushing and dredging device for long-distance pipeline transportation of coal gangue slurry in order to solve the above-mentioned problems.

A dredging mechanism is provided at one end of the water supply mechanism. The water supply mechanism includes an inner pipe, one end of which is fixed with a water spray pipe, and the other end of which is connected to the outlet of a high-pressure water station. Two symmetrical levers are fixed on the outside of the water spray pipe. An annular sleeve is fixed on the end of the water spray pipe away from the inner pipe, and a support spring is fixed on the end of the annular sleeve close to the inner pipe. The support spring is sleeved on the outside of the water spray pipe. The unblocking mechanism includes a flushing nozzle, which is slidably connected to the outside of the water spray pipe.

An impeller shaft is fixed to the inside of the conical end of the flushing nozzle. An impeller is fixed to one end of the impeller shaft that extends into the annular sleeve. A hammering component is provided on one side of the slide frame.

[0005] Preferably, the center of the slide frame has a sliding hole for sliding on the outside of the water spray pipe, and the end of the support spring away from the annular sleeve abuts against the side of the slide frame. The outside of the rinsing nozzle has a spiral spray nozzle located at the position of the spiral fin, and the end of the rinsing nozzle away from the spiral fin has a jet hole.

[0006] Preferably, the hammering assembly includes an impact ring, which is fitted around the outside of the water spray pipe.

All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-9As shown, a long-distance pipeline transportation flushing and dredging device for coal gangue slurry includes a high-pressure water station 4, a material suction mechanism 3 on one side of the high-pressure water station 4, and a water supply mechanism 2 located inside the material suction mechanism 3. A dredging mechanism 1 is provided at one end of the water supply mechanism 2.

[0017] In this embodiment: the water supply mechanism 2 includes an inner pipe 24, one end of which is fixed with a water spray pipe 21, and the other end of which is connected to the outlet of the high-pressure water station 4. Two symmetrical levers 22 are fixed on the outside of the water spray pipe 21. An annular sleeve is fixed on the end of the water spray pipe 21 away from the inner pipe 24, and a support spring 23 is fixed on the end of the annular sleeve close to the inner pipe 24. The support spring 23 is sleeved on the outside of the water spray pipe 21. The high-pressure water flow is sent into the interior of the water spray pipe 21 through the inner pipe 24 and sprayed into the unblocking mechanism 1 from the annular sleeve of the water spray pipe 21. At the same time, the support spring 23 is used to support the position of the unblocking mechanism 1.

[0018] In this embodiment: the unblocking mechanism 1 includes a flushing nozzle 11, which is slidably connected to the outside of the water spray pipe 21. A spiral fin 12 is fixed to the outside of the conical end of the flushing nozzle 11. A slide frame 13 is fixed inside the flushing nozzle 11. An impeller shaft 14 is fixed to the inside of the conical end of the flushing nozzle 11. An impeller is fixed to one end of the impeller shaft 14 that extends into the annular sleeve. A sliding hole for sliding on the outside of the water spray pipe 21 is opened in the center of the slide frame 13, and the end of the support spring 23 away from the annular sleeve abuts against the side of the slide frame 13. A spiral spray nozzle is opened on the outside of the flushing nozzle 11 at the position of the spiral fin 12. A jet hole is opened on the end of the flushing nozzle 11 away from the spiral fin 12. An impact ring 15 is provided on one side of the slide frame 13. Two symmetrically arranged impact arms 16 are fixed to the side of the impact ring 15 near the slide frame 13, fitted onto the outside of the water spray pipe 21. A storage spring is provided between the impact ring 15 and the slide frame 13, located outside the two impact arms 16. The two impact arms 16 are attached to the outside of the water spray pipe 21. The water flow sprayed from the water spray pipe 21 into the flushing nozzle 11 drives the impeller to rotate. At the same time, the impeller drives the entire flushing nozzle 11 to rotate around the water spray pipe 21 through the impeller shaft 14. At this time, the rotation of the flushing nozzle 11 drives the spiral fins 12 to drill through the accumulated coal gangue. Simultaneously, water is sprayed out through the spiral nozzle on the outside of the flushing nozzle 11. At this time, the flushing nozzle 11 will also rotate under the action of the water flow sprayed from the spiral nozzle. The water jet from the spiral nozzle provides partial driving force, while the water flow from the spiral nozzle carries the coal gangue particles towards one end of the suction mechanism 3. Simultaneously, the water flow from the jet nozzle pushes the flushing nozzle 11 away from the suction mechanism 3, and the water flow from the jet nozzle washes the flushed coal gangue particles into the suction mechanism 3, where the suction mechanism 3 can then remove the flushed coal gangue particles. Furthermore, as the flushing nozzle 11 rotates around the water spray pipe 21, the sliding plate frame 13 also rotates synchronously around the water spray pipe 21. At this time, the energy storage spring connected to the sliding plate frame 13 drives the impact ring 15 to rotate synchronously around the water spray pipe 21. During the rotation of the impact ring 15, the two impact arms 16 on the impact ring 15 rotate to the two levers of the water spray pipe 21. At block 22, as the impact ring 15 continues to rotate, the two impact arms 16 on the impact ring 15 are pushed by the pusher block 22, causing the impact ring 15 to move synchronously away from the slide frame 13 as it rotates. At this time, the energy storage spring begins to store energy. When the impact arms 16 pass the pusher block 22, the impact ring 15 will move rapidly towards the slide frame 13 along the outside of the water spray pipe 21 under the action of the energy storage spring. Then, the two impact arms 16 will impact the slide frame 13. The force of the impact on the slide frame 13 will be transmitted to the flushing nozzle 11, causing the flushing nozzle 11 to move synchronously along the outside of the water spray pipe 21. Then, the conical end of the flushing nozzle 11 will penetrate into the accumulated coal gangue particles, which can then be dispersed from the inside.Simultaneously, the flushing nozzle 11 drives the spiral fins 12 to rotate, drilling and clearing away the accumulated coal gangue particles.

[0019] In this embodiment: the suction mechanism 3 includes a guide tube 32, the front end of which is connected to a collection cylinder 33, and the rear end of which is connected to a suction outer tube 31. A vacuum pump 34 is provided on one side of the collection cylinder 33, and the top of the collection cylinder 33 is connected to the suction port of the vacuum pump 34 through a conduit. The suction outer tube 31 is sleeved on the outside of the inner tube 24. A conical suction hood is fixed at the end of the suction outer tube 31 away from the guide tube 32. A perforation is opened at the end of the suction outer tube 31 near the guide tube 32 for the inner tube 24 to pass through. Multiple circumferentially distributed support rods are fixed inside the conical suction hood of the suction outer tube 31. Each support rod is fixedly connected to the inner tube 24 at the end away from the conical adsorption hood. The vacuum pump 34 is used to draw the inside of the collection cylinder 33 through the conduit. At this time, the collection cylinder 33 will draw the inside of the suction pipe 31 through the guide pipe 32. Then, the suction pipe 31 and the inner tube 24 will be in a low-pressure area, and suction will be formed at the conical adsorption hood of the suction pipe 31. The coal gangue particles that flow down during the flushing and clearing will be drawn into the space between the suction pipe 31 and the inner tube 24 by the conical adsorption hood. Then, the coal gangue particles will enter the collection cylinder 33 for collection through the guide pipe 32.

[0020] Working principle: In use, firstly, the unblocking mechanism 1 and the water supply mechanism 2 are placed into the pipe that needs to be unblocked. At this time, high-pressure water is supplied into the inner pipe 24 through the high-pressure water station 4. The high-pressure water in the inner pipe 24 enters the spray pipe 21. The water flow sprayed into the flushing nozzle 11 through the annular sleeve of the spray pipe 21 drives the impeller to rotate. At the same time, the impeller drives the entire flushing nozzle 11 to rotate around the spray pipe 21 through the impeller shaft 14. At this time, the rotation of the flushing nozzle 11 drives the spiral fins 12 to drill and remove the accumulated coal gangue. At the same time, water is sprayed out through the spiral nozzles on the outside of the flushing nozzle 11. The flushing nozzle 11 is also affected by the water flow sprayed out by the spiral nozzles. The water jet from the spiral nozzle provides partial driving force for the rotation of the flushing nozzle 11. The water jet from the spiral nozzle carries the coal gangue particles towards one end of the suction pipe 31. Simultaneously, the water jet from the jet nozzle pushes the flushing nozzle 11 away from the suction pipe 31. The water jet from the jet nozzle flushes the washed-down coal gangue particles into the suction pipe 31. At this point, the vacuum pump 34 draws suction from the inside of the collection cylinder 33 through the guide pipe 32. The collection cylinder 33 then draws suction from the inside of the suction pipe 31 through the guide pipe 32. Consequently, a low-pressure area is created between the suction pipe 31 and the inner pipe 24, forming suction at the conical adsorption hood of the suction pipe 31. When the suction pipe is flushed and cleared... The flowing coal gangue particles are sucked into the space between the outer suction pipe 31 and the inner pipe 24 by the conical adsorption hood. Then, the coal gangue particles pass through the guide pipe 32 and enter the collection cylinder 33 for collection. Furthermore, when the flushing nozzle 11 rotates around the water spray pipe 21, the sliding plate frame 13 also rotates synchronously around the water spray pipe 21. At this time, the energy storage spring connected to the sliding plate frame 13 drives the impact ring 15 to rotate synchronously around the water spray pipe 21. During the rotation of the impact ring 15, the two impact arms 16 on the impact ring 15 rotate to the two levers 22 on the water spray pipe 21. As the impact ring 15 continues to rotate, the two impact arms 16 on the impact ring 15 are pushed by the levers 22, causing the impact ring 15 to rotate... Simultaneously moving away from the slide frame 13, the energy storage spring begins to store energy. When the impact arm 16 rotates past the toggle block 22, the impact ring 15 will move rapidly towards the slide frame 13 along the outside of the water spray pipe 21 under the action of the energy storage spring. Then, the two impact arms 16 will impact the slide frame 13. At this time, the force of impacting the slide frame 13 will be transmitted to the flushing nozzle 11, causing the flushing nozzle 11 to move synchronously along the outside of the water spray pipe 21. Then, the conical end of the flushing nozzle 11 will be inserted into the accumulated coal gangue particles. At this time, the accumulated coal gangue particles can be dispersed from the inside. At the same time, the rotation of the spiral fin 12 driven by the flushing nozzle 11 will drill open and clear the accumulated coal gangue particles.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
