Because the cementing active material is added into the filling slurry, the slurry has stronger viscosity, and a large amount of water is required to be used for continuously flushing the pipeline after each filling is finished, so that the pipeline is smooth, and the next use is not influenced. However, in the actual use process, the materials in the pipeline are difficult to thoroughly clean. After a certain period of time, the inner wall of the pipeline will accumulate a mixture after slurry solidification with a certain thickness, and if deep cleaning is not performed, the following adverse effects will occur:

1) The inner wall of the pipeline is smaller and smaller, the conveying resistance of the filling slurry is increased, the conveyable flow is reduced, the mining and filling balance of the mine is affected, and the filling operation cost is increased.

2) The inner wall becomes uneven, influences the conveying smoothness of ground paste, increases the vortex state in the transportation process, and indirectly increases the risk of pipe blockage and pipe explosion.

3) Because the inner wall of the pipeline is stressed unevenly in the conveying process, the areas with lighter flushing have more accumulated materials, the slurry can further flush other areas more, the abrasion of the pipeline is accelerated, the replacement time of the pipeline is shortened, and the filling operation cost is increased.

4) After the inner wall of the pipeline forms a layer of scaling material, the adhesion adsorption speed of the material on the scaling material can be greatly increased, and the control is difficult.

In order to solve the problems, and avoid the negative influence caused by accumulation of materials on the inner wall of a filling pipeline, the invention patent with the patent number of CN202310285767.2 discloses a multifunctional mud cleaning device of a pipeline machine for water conservancy construction; including being located the power aircraft nose of front side, be equipped with the power control assembly that provides power for whole device in the power aircraft nose, the rear end of power aircraft nose rotates the installation and coaxial cross axle with it, is equipped with the first power device of drive cross axle pivoted in the power aircraft nose, and the pivot outside is equipped with the clear mud subassembly of pipe wall, and the columniform tail with it is installed through coupling assembling to the rear end of cross axle, and the tail lower part is equipped with the mud subassembly that absorbs mud with the pipeline bottom, and the mud subassembly that absorbs mud is connected with outside high-pressure mud absorbing device through connecting the conveying subassembly.

Detailed Description

Specifically, the high-pressure water flow flushing channel 11 is arranged in the scale remover 1 in a radially outwards inclined extending manner along the axial direction of the scale remover 1, and is used for guiding the high-pressure water flow which is impacted axially to the pipe wall of the filling pipe towards the front end of the scale remover 1, so that the high-pressure water flow can clean the filling pipe in the moving process of the scale remover 1, and the refractory scale attached to the pipe wall can be cleaned deeply.

Example 1

The embodiment 1 of the invention provides a high-efficiency cleaning device for the inner wall of a filling pipeline, as shown in fig. 1 to 5, which comprises a scale removing body 1 matched with the inner diameter of the pipeline, a plurality of high-pressure water flow flushing channels 11 and a plurality of high-pressure water flow flushing channels 12 arranged in the scale removing body 1, wherein the plurality of high-pressure water flow flushing channels 11 are circumferentially distributed on the outer edge of the scale removing body 1, each high-pressure water flow flushing channel 11 penetrates through the scale removing body 1 along the axial direction of the scale removing body 1, and a water outlet 101 of the high-pressure water flow flushing channel is obliquely arranged outwards along the radial direction of the scale removing body 1; the air outlet of the high-pressure air flow flushing channel 12 is arranged close to the water outlet 101 of the high-pressure water flow flushing channel 11.

The high-pressure water flow flushing channels 11 circumferentially distributed on the outer edge of the scale remover 1 can guide the high-pressure water flow to the front end of the displacement direction of the scale remover 1 under the impact of the high-pressure water flow, so that the high-pressure water flow flushes the front end pipe body of the scale remover 1 under the guide of the high-pressure water flow flushing channels 11. In addition, the air outlet of the high-pressure air flow flushing channel 12 is arranged close to the water outlet 101 of the high-pressure air flow flushing channel 11, so that high-pressure water flow and high-pressure air output by the high-pressure air flow flushing channel 12 are mixed at the water outlet 101 to form a gas-liquid two-phase cleaning medium, the volume of the high-pressure water flow is multiplied, the flow speed of water is accelerated, the water is in a jet boiling state, the impact, cutting and air explosion can be carried out on the pipe wall, and further the deep cleaning of a filling pipeline is realized.

Specifically, the high-pressure water flow flushing channel 11 is arranged in the scale remover 1 in a radially outwards inclined extending manner along the axial direction of the scale remover 1, and is used for guiding the high-pressure water flow which is impacted axially to the pipe wall of the filling pipe towards the front end of the scale remover 1, so that the high-pressure water flow can clean the filling pipe in the moving process of the scale remover 1, and the refractory scale attached to the pipe wall can be cleaned deeply.

The impact direction of the high-pressure water flow is consistent with the extending direction of the pipeline, namely, the axial direction of the scale remover 1, but because the high-pressure water flow flushing channel 11 has a certain angle deviation compared with the axial direction of the scale remover 1, when the high-pressure water flow impacts the scale remover 1, the impact force of the water flow can be reduced due to the angle deviation between the high-pressure water flow flushing channel 11, so that more impact force acts on the body of the scale remover 1, the displacement speed of the scale remover 1 in a filling pipe body is higher, and the cleaning effect of the filling pipeline cannot be ensured.

In order to avoid the problem that the body of the scale remover 1 receives a large impact force and the displacement speed of the high-pressure water flow in the filling pipe body is high, as shown in fig. 1 to 3, the high-pressure water flow flushing channel 11 comprises a diversion section 111 and a flushing section 112 connected with the diversion section 111, and the diversion section 111 is used for guiding the high-pressure water flow to the flushing section 112 along the direction of the high-pressure water flow, so that the problem that the high-pressure water flow can not guarantee the cleaning effect of the filling pipe due to the fact that the large impact force is applied to the body of the scale remover 1 is avoided; the flushing section 112 is used for guiding the high-pressure water flow which is impacted axially to the pipe wall of the filling pipe towards the front end of the scale remover 1, so that the high-pressure water flow cleans the filling pipe in the moving process of the scale remover 1. As shown in fig. 1 to 3, a plurality of water inlets 102 are circumferentially distributed near the center on one axial side of the scale remover 1, a plurality of water outlets 101 are circumferentially distributed near the outer edge on the other axial side of the scale remover, and the water inlets 102 and the water outlets 101 are staggered from each other in the axial projection direction. The guide section 111 is connected with the water inlet 102, extends along the axial direction of the scale remover 1 and is perpendicular to the body of the scale remover 1 in the scale remover 1 to be connected with one end of the flushing section 112, and the flushing section 112 is connected with the guide section 111 and extends along the axial direction of the scale remover 1 in a radial outward inclined manner to be connected with the water outlet 101, so that high-pressure water flow is guided to the wall of a filling pipeline towards the front end of the scale remover 1, and the high-pressure water flow is enabled to perform pipe body cleaning and simultaneously focus on deep cleaning of stubborn scale attached to the pipe wall.

It is further preferred that the flushing segments 112 of the high pressure water flushing channel 11 are arranged obliquely in a clockwise or counter-clockwise direction simultaneously with the radially outwardly extending arrangement in the descaling unit 1, forming a high pressure water flushing channel 11 which is directed clockwise or counter-clockwise, as shown in fig. 1 to 3. When the high-pressure water flow is guided by the high-pressure water flow flushing channel 11 to impact the pipe wall of the filling pipe at the front end of the scale remover 1, the reaction force of the high-pressure water flow impacting the pipe wall pushes the scale remover 1 to rotate clockwise or anticlockwise so as to form tangential motion; therefore, circumferential flushing of the pipe wall of the filling pipe can be realized, and the pipe wall of the filling pipe is cleaned more comprehensively; the risk of stuck shells between the scale remover 1 and the pipe wall can also be reduced.

The air outlets of the high-pressure air flow flushing channels 12 are arranged along the distribution positions of the high-pressure water flow flushing channels 11 in one-to-one correspondence and close to the water outlets 101 of the high-pressure water flow flushing channels 11, and the output high-pressure air and the high-pressure water flow are mixed to form a gas-liquid two-phase cleaning medium; the compressed air gas is used as a pressure medium, and generates a high pressure or vacuum area in the mixing process with high pressure water flow, so that the volume of the water flow is multiplied, the flow speed of the water is accelerated, the water is in a jet boiling state, and the compressed air gas has good effects of impact, cutting, gas explosion and the like in the pipe wall action process, and the deep cleaning of a filling pipe is realized. As shown in fig. 3 and 4, the high-pressure air flow flushing channel 12 is arranged at one side of the scale remover 1 where the water outlet 101 of the high-pressure water flow flushing channel 11 is arranged, and extends radially from the center of the scale remover 1 to the periphery, and extends radially to the water outlet 101 of the high-pressure water flow flushing channel 11 in the scale remover 1; the high-pressure water flow and the high-pressure gas output by the high-pressure water flow flushing channel 12 are mixed at the water outlet 101 to form a gas-liquid two-phase cleaning medium, and the filling pipeline is deeply cleaned. Preferably, since the high-pressure water flow flushing channel 11 is inclined in a clockwise or counterclockwise direction, the impact pressure application area of the sprayed water flow is increased, and thus the high-pressure water flow flushing channel 12 may be provided at a distance from the water outlet 101.

As shown in fig. 2 to 4, the center of the scale remover 1 is provided with a high-pressure air inlet 103; the high-efficiency cleaning device for the inner wall of the filling pipeline comprises a high-pressure gas injection assembly, the high-pressure gas injection assembly comprises a compressor and a high-pressure gas injection pipeline 2, one end of the high-pressure gas injection pipeline 2 is in sealing connection with the output end of the compressor, and the other end of the high-pressure gas injection pipeline is connected with a high-pressure gas flow flushing channel 12 in the scale remover 1 through a high-pressure gas inlet 103. Specifically, in order to avoid the influence of the arrangement of the high-pressure gas injection pipeline 2 on the effect of the high-pressure water flow on the scale remover 1, the compressor is positioned at the scale discharging end of the filling pipeline, one end of the high-pressure gas injection pipeline 2 is in sealing connection with the high-pressure gas inlet 103, and the other end of the high-pressure gas injection pipeline extends to the scale discharging end along the filling pipeline to be in sealing connection with the output end of the compressor.

The outer peripheral surface of the scale remover 1 is sleeved with a flexible sealing layer 13, and the flexible sealing layer 13 is preferably a rubber layer adhered to the outer peripheral surface of the scale remover 1 by adopting strong industrial glue. When the scale remover 1 is axially displaced under the impact of high-pressure water flow, the rubber layer can prevent water flow from overflowing between the scale remover 1 and the pipe wall and has certain compressibility, so that the phenomenon of shell blocking caused by the subtle change of the inner diameter of the pipeline can be avoided, the inner wall of the pipeline is protected, and scratch damage is avoided. Preferably, the rubber layer has the thickness of 10-15 mm, good wear resistance and strong elasticity, and can form better fitting degree and sealing performance with the inner wall of the pipeline.
