Description

Technical Field

[0001] The present application relates to the technical field of paste conveying pipelines, and in particular to a multi-stage speed regulating device for deep well filling. Background Art

[0002] As the country's support for mine paste filling technology increases, paste filling technology continues to innovate and develop, and the application areas and market scale of the mine paste filling industry are also expanding. The use of paste filling technology in mine resource development can effectively improve mine mining efficiency, reduce the impact on mine mining safety, and protect the mine ground environment.

[0003] At present, the paste filling technology in mines mainly transports paste slurry to the underground through the pipeline transportation system. When the paste slurry flows in the deep well filling pipeline with large height difference, the acceleration generated by gravity is greater than the pipeline transportation resistance, and the paste slurry flow rate continues to increase, making the slurry flow rate in the pipeline proportional to the influence of pipeline wear. The solid particles in the paste slurry make irregular movements such as impact, grinding and collision on the pipeline flow surface, which can easily cause the pipeline to be damaged, deformed, worn and fatigued, reducing the service life of the filling pipeline and increasing the risk factor of paste filling. Utility Model Content

[0023] At present, the paste filling technology in mines mainly transports paste slurry to the underground through the pipeline transportation system. When the paste slurry flows in the deep well filling pipeline with large height difference, the acceleration generated by gravity is greater than the pipeline transportation resistance, and the paste slurry flow rate continues to increase, making the slurry flow rate in the pipeline proportional to the influence of pipeline wear. The solid particles in the paste slurry make irregular movements such as impact, grinding and collision on the pipeline flow surface, which can easily cause the pipeline to be damaged, deformed, worn and fatigued, reducing the service life of the filling pipeline and increasing the risk factor of paste filling.

[0024] In response to the above problems, an embodiment of the present application provides a deep well filling multi-stage speed regulation device, which can control the flow rate of filling slurry and reduce the wear and damage of the pipeline caused by the high-speed movement of the paste slurry by arranging multiple groups of speed regulation conveying pipes in sections in the large height difference filling pipeline; utilize the paste buffer zone at the top of the buffer pipeline to prevent the paste slurry from directly colliding with the pipeline wall during vertical free fall, reduce the impact force of the paste slurry on the pipeline, reduce the flow rate of the paste slurry, cooperate with the horizontal speed regulation elbow, increase the resistance of the paste slurry in the horizontal speed regulation elbow, control the flow rate of the paste slurry, reduce the wear on the filling pipeline, and improve the safety factor of the paste slurry filling.

[0025] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0026] Figure 1 It is a structural schematic diagram of a deep well filling multi-stage speed regulation device shown in an embodiment of the present application.

[0027] See also Figure 1 , a deep well filling multi-stage speed regulating device, comprising:

[0028] The first vertical pipeline 1, the first buffer pipeline 2, the first horizontal speed regulating elbow 3, the second vertical pipeline 4, the second buffer pipeline 5, the second horizontal speed regulating elbow 6, the paste slurry 7 and the paste buffer zone 8.

[0029] The first buffer pipe 2 is mounted on the bottom of the first vertical pipe 1. The thickness and strength of the first buffer pipe 2 are greater than those of the first vertical pipe 1, ensuring that when the paste slurry 7 falls from the first vertical pipe 1 into the first buffer pipe 2, the first buffer pipe 2 can withstand the impact force without deformation and breakage. The first horizontal speed regulating bend 3 is vertically installed on the first buffer pipe 2. The first horizontal speed regulating bend 3 is composed of two or more "U"-shaped pipes. The number of bends in the first horizontal speed regulating bend 3 is determined by the filling line coefficient N. The calculation formula of the filling line coefficient N is: N = (L + H) / L, where H is the height of the vertical pipe and L is the length of the horizontal speed regulating bend.

[0030] The buffer pipe part below the connection position between the first horizontal speed regulating bend 3 and the first buffer pipe 2 is a paste buffer zone 8, and the paste buffer zone 8 is filled with paste slurry 7. The filled paste slurry 7 overflows to the mouth of the first horizontal speed regulating bend 3. After the falling paste slurry 7 is buffered by the paste buffer zone 8, it flows into the first horizontal speed regulating bend 3 by gravity, and the pressure generated when the paste slurry 7 falls into the paste buffer zone 8 is reduced through the bend.

[0031] The second vertical pipeline 4, the second buffer pipeline 5, the second horizontal speed regulating elbow 6, the paste slurry 7 and the paste buffer 8

[0032] The top of the second vertical pipeline 4 is connected to the end of the first horizontal speed regulating elbow 3, the second buffer pipeline 5 is installed at the lower end of the second vertical pipeline 4, the lower part of the second buffer pipeline 5 is also provided with a buffer zone, and the second horizontal speed regulating elbow 6 is installed on the second buffer pipeline 5. By analogy, two or more sections of speed regulating and conveying pipelines are arranged to form a deep well filling multi-stage speed regulating device, realize multi-stage speed regulation of deep wells with large height differences, reduce the wear of the filling pipeline by the paste slurry 7, and improve the safety factor of the paste slurry filling.

[0033] When used in this application, the paste slurry 7 overcomes the transportation resistance of the first vertical pipeline 1, flows by gravity to the first buffer pipeline 2, impacts the paste buffer zone 8 formed by the residual paste slurry 7 at the bottom of the first buffer pipeline 2, reduces the flow rate of the paste slurry 7, and reduces the impact force of the paste slurry 7 on the filling pipeline. The paste slurry 7 flows by gravity to the first horizontal speed regulating bend 3 through the first buffer pipeline 2. Through the special U-shaped structure of the first horizontal speed regulating bend 3, the number of bends of the paste slurry 7 is increased, the pipeline resistance is increased, and the flow rate of the paste slurry 7 is rapidly reduced. The low-speed paste slurry 7 can reduce the filling line coefficient (the filling multiple line indicates the filling range that can be achieved by gravity transportation). Subsequently, the paste slurry 7 enters the second vertical pipeline 4, the second buffer pipeline 5 and the second horizontal speed regulating bend 6 in turn for multi-stage speed regulation. Through the joint operation of the above-mentioned structures, multi-stage speed regulation of the deep well large height difference filling line can be achieved, the wear of the paste slurry 7 on the filling pipeline can be reduced, and the safety factor of the paste slurry filling can be improved.

[0034] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
