Description

Technical Field

[0001] The invention relates to the technical field of gangue filling, and in particular to a gangue pipeline flushing-free system. Background Art

[0002] Gangue filling technology is an important part of the existing technology used in coal mining operations. Gangue refers to rocks mixed into the coal mine during the mining process. In the subsequent processing of the coal mine, the gangue will be sorted out from the ore. Because the gangue is hard, in order to recycle the gangue, the gangue is crushed, mixed with cement, and then re-filled into the tunnels or goafs in the mine to support the interior of the mine and improve the internal stability of the mine. The method of filling and transporting gangue in the existing technology is to install a conveying pipeline in the tunnel in the mine, mix the gangue and a curing agent such as cement into a filling paste on the ground, and then add it to the conveying pipeline in the tunnel. There are multiple connecting joints on the conveying pipeline, and the filling paste is removed from the conveying pipeline through the corresponding connecting joints, so that the filling paste enters the corresponding filling area to complete the gangue filling operation.

[0003] However, the gangue filling technology in the prior art has the following disadvantages during actual use: the gangue paste is mixed with cement and other curing agents on the ground and then transported into the conveying pipeline. However, when the conveying of the gangue paste is stopped, the gangue paste in the conveying pipeline will solidify in a short time because the curing agent is mixed in the gangue gypsum. Therefore, every time the conveying operation of the gangue gypsum needs to be suspended for a long time, the conveying pipeline needs to be flushed to ensure that there is more gangue paste in the conveying pipeline to avoid blockage of the conveying pipeline. However, this method of conveying the gangue paste has a certain waste of water resources when flushing the inside of the conveying pipeline because the conveying pipeline has a certain length, and most of the gangue paste flushed out of the conveying pipeline cannot be used directly, which will also cause waste of the gangue paste.

Each connecting joint 3 is provided with a stop valve, so that the gangue paste conveyed in the conveying pipeline 1 is discharged through the corresponding connecting joint 3. The mobile device 2 is a kind of rotary self-moving device in the prior art, which is moved by wheels. It is a prior art device known to technical personnel in this field.

Due to the limitation of the internal space of the mine, in order to make the mobile device 2 and various components installed on the mobile device 2 easier to move in the mine, the height of the mixing cylinder 4 is adjusted by the scissor-type lifting structure 10. During the movement of the mobile device 2, the mixing cylinder 5 is made as close to the mobile device 2 as possible, and the scissor-type lifting structure 10 can make the mixing cylinder 4 as close to the top of the mobile device 2 as possible, so as to reduce the deployment area of ​​the whole device.

[0022] The number of the mixing drums 5 is set to two, and the two mixing drums 5 are both arranged on the mobile device 2 through the installation and adjustment assembly 200. The installation and adjustment assembly 200 includes a mounting frame 14, a sliding plate 16 and a driving electric cylinder 18. The mixing drum 5 is fixedly connected in the mounting frame 14.

A driving electric cylinder 18 is arranged on the side of the mobile device 2 away from the rotating seat 15. The output end of the driving electric cylinder 18 is rotatably connected to the rotating shaft 17. When it is necessary to adjust the inclination angle of the mixing drum 5, the driving electric cylinder 18 is started to drive the rotating shaft 17 to slide on the sliding plate 16, and the mounting frame 14 is pushed to flip along the adjusting shaft rotatably connected to the rotating seat 15, thereby adjusting the inclination angle of the mixing drum 5. The mixing drum 5 is provided with a mixing and conveying assembly 300, and also includes a partition plate 11. The partition plate 11 is fixedly connected to the middle of the mixing drum 5, and the partition plate 11 divides the mixing drum 5 into a mixing chamber 12 and a conveying chamber 13. The partition plate 11 is connected to a plurality of drain pipes, and a cavity is provided in the partition plate 11.

The driving shaft 19 is rotatably connected in the stirring cylinder 5, and the driving shaft 19 is rotatably connected to the partition plate 11. The stirring cylinder 5 is provided with a first drive motor 20, and the output end of the first drive motor 20 is fixedly connected to the driving shaft 19. The spiral stirring blade 21 is fixedly connected to one side of the driving shaft 19, and the spiral stirring blade 21 is located in the mixing chamber 12. The spiral conveying blade 22 is fixedly connected to the other side of the driving shaft 19, and the spiral conveying blade 22 is located in the conveying chamber 13. After cement and other curing agents and gangue paste are transported together to the mixing chamber 12 in the mixing drum 5, the first drive motor 20 is started to drive the drive shaft 19 to rotate in the partition plate 11 and the mixing drum 5. Because the height of the mixing chamber 12 is higher than the height of the conveying chamber 13 after the mixing drum 5 is adjusted inclination angle, the cement and other curing agents and gangue paste are mixed by the spiral stirring blades 21 and then move into the conveying chamber 13. After the mixed gangue paste filler enters the conveying chamber 13, the mixed gangue filler is discharged from the mixing drum 5 through the spiral conveying blades 22.

A plurality of discharge valves are connected to the inner arc surface of the annular injection cylinder 24. The two annular injection cylinders 24 are connected by a connecting pipe 26, and the output end of the delivery pump device 23 is connected to the connecting pipe 26. When it is necessary to add cement or other curing agents into the two mixing cylinders 5, the delivery pump device 23 is started to discharge the cement or other curing agents from the discharge cylinder 6, and the cement or other curing agents are delivered to the two annular injection cylinders 24 through the connecting pipe 26, so that the cement or other curing agents are dispersed and discharged through multiple discharge pipes 25, thereby improving the mixing effect of the cement or other curing agents and the gangue gypsum.

[0024] The mixing cylinder 5 is provided with a paste connecting component 500, which is connected with the corresponding connecting joint 3. The paste connecting component 500 includes a semi-arc injection cylinder 27 and a filling cylinder 29.

A plurality of flow notches 32 are provided on the circumference of the mounting seat 30. A connecting pipeline 33 is connected between the filling cylinder 29 and the corresponding connecting joint 3. When needed, When the gangue paste in the conveying pipeline 1 is added to the mixing chamber 12, the connecting pipeline 33 is connected between the filling cylinder 29 and the connecting joint 3, so that the gangue paste enters the filling cylinder 29 through the connecting pipeline 33. In order to maintain the solid-liquid balance of the gangue paste when entering the semi-arc injection cylinder 27, after the gangue paste enters the filling cylinder 29, the spiral column 31 is used to make the gangue paste have a swirling effect, so that the gangue paste completes a certain mixing operation during the flow process, and after the gangue paste enters the semi-arc injection cylinder 27, the gangue paste is discharged through multiple drainage ports 28 to complete the dispersed discharge of the gangue paste and improve the mixing effect of the gangue paste and curing agents such as cement.

The mounting seat 30 is fixedly connected in the discharge cylinder 34 to improve the mixing effect of the gangue filler during the flow process, and the gangue filler can be transported to the designated filling area through the pumping equipment 35 and the discharge pipe 41. Because the mixing cylinder 5 is located at two positions, the gangue filler can be transported to the discharge pipe 41 on one side through the interconnecting pipeline 36, so that the two mixing cylinders 5 can perform gangue filling operations.

[0026] The working principle of the gangue pipeline flushing-free system: When it is necessary to carry out gangue filling operation on the corresponding area in the mine, firstly, the mixing cylinder 4 and the mixing cylinder 5 are moved to the designated position by the mobile device 2, and then the mixing cylinder 4 is driven to rise by the scissor lift structure 10, and the driving electric cylinder 18 is started to drive the rotating shaft 17 to slide on the sliding plate 16, so that the mounting frame 14 and the mixing cylinder 5 are tilted, and then cement and other curing agents are added into the mixing cylinder 4, and the second driving motor 37 is started, and the two connecting shafts 38 are driven to rotate synchronously through the transmission effect of the transmission gear 39 and the transmission toothed belt 40, and then the rotating shaft 1 7 and the rotating shaft 2 8 are driven to rotate synchronously together, so that the rotating shaft 1 7 and the rotating shaft 2 8 drive the conical spiral stirring blades 9 to rotate together, so that the conical spiral stirring blades 9 can fully mix various cement and other curing agent raw materials added into the mixing cylinder 4; Then, the connecting pipe 33 is used to connect the filling cylinder 29 with the corresponding connecting joint 3, so that the gangue paste in the conveying pipe 1 enters the filling cylinder 29. After the gangue paste enters the filling cylinder 29, the spiral column 31 causes the gangue paste to have a swirling effect, so that the gangue paste completes a certain mixing operation during the flow process. After the gangue paste enters the semi-arc injection cylinder 27, the gangue paste is discharged through multiple discharge ports 28, and then the conveying pump device 23 is started to discharge the cement and other curing agents from the discharge cylinder 6, and the cement and other curing agents are conveyed to the two annular injection cylinders 24 through the connecting pipe 26, so that the cement and other curing agents are dispersed and discharged through multiple discharge pipes 25; Restart the first drive motor 20 to drive the drive shaft 19 to rotate in the partition plate 11 and the mixing drum 5. Because after the inclination angle of the mixing drum 5 is adjusted, the height of the mixing chamber 12 is higher than the height of the conveying chamber 13, so that the cement and other curing agents and the gangue paste are mixed by the spiral mixing blades 21 and move into the conveying chamber 13. After the mixed gangue paste filler enters the conveying chamber 13, the mixed gangue filler is discharged from the mixing drum 5 by the spiral conveying blades 22, and then the gangue filler can be transported to the designated filling area through the pumping equipment 35 and the discharge pipe 41. Because the mixing drum 5 is located at two positions, the gangue filler can be transported to the discharge pipe 41 on one side through the interconnecting pipeline 36, so that both mixing drums 5 can perform gangue filling operations.
