[0002] In order to rationally utilize waste resources and improve the safety of coal mining, the paste filling technology of mines was developed. The paste filling technology of mines is to mix raw materials such as coal gangue and fly ash into paste and pump it into the mine to reduce surface collapse, improve resource recovery rate and reduce environmental pollution. The paste filling process of mines requires sufficient stirring of the raw materials for preparing the paste to ensure the fluidity, stability and filling performance of the obtained paste.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

A through-distributed material inlet 15 is fixedly disposed at the right end of the stirring tank 14, and a through-distributed material outlet 16 is fixedly disposed at the left end of the stirring tank 14. A vertically distributed L-shaped side plate 31 is fixedly disposed on the right side of the inclined plate 3, a through-distributed fixed pipe 18 is fixedly disposed on the top of the L-shaped side plate 31, and the left end of the fixed pipe 18 is rotatably inserted on the inner annular surface of the feed port 15; A tripod 25 is fixedly arranged on the inner annular surface of the discharge port 16, a hollow shaft 21 is rotatably inserted into the middle of the right side of the fixed pipe 18, a central shaft 23 is rotatably inserted into the hollow shaft 21, and the left end of the central shaft 23 is rotatably inserted into the middle of the tripod 25; The left section of the hollow shaft 21 is fixed with a first stirring blade 22 with a continuous spiral distribution, and the left section of the central shaft 23 is fixed with a second stirring blade 24 with a continuous spiral distribution, and the second stirring blade 24 is symmetrically distributed with the first stirring blade 22; the first stirring blade 22 and the second stirring blade 24 can fully stir raw materials such as coal gangue, cement and water to form a paste that meets the requirements. The embodiment of the present invention does not specifically limit the raw materials and proportions of the paste.

[0020] It should be noted that: in this embodiment, a pair of symmetrically distributed fixed side plates 13 are fixed on both sides of the top surface of the inclined plate 3, and a circular through hole is opened on the top of each fixed side plate 13. The middle part of the outer ring surface of the feed inlet 15 and the discharge outlet 16 is sleeved with a concentric fixed fixing ring 17, and each fixing ring 17 is rotatably engaged in the circular through hole on the same side; A concentrically fixed dust cover 19 is sleeved on the middle of the outer ring surface of the fixed pipe 18, and the dust cover 19 is rotatably sleeved on the outer ring surface of the feed inlet 15, and a plurality of penetrating raw material conveying pipes 20 are fixed on the right side surface of the fixed pipe 18; raw materials such as coal gangue, cement and water can be injected into the mixing tank 14 along the raw material conveying pipes 20; The outer diameter of the fixed pipe 18 is 2-3 cm smaller than the inner diameter of the feed port 15 to prevent the mixing tank 14 from rubbing against it due to mechanical vibration during stirring; at the same time, in order to prevent impurities from entering the mixing tank 14 from the gap, a dust cover 19 is installed on the fixed pipe 18, and the inner diameter of the dust cover 19 is 2-3 cm larger than the outer diameter of the feed port 15.

[0021] In the specific implementation process, Figure 7 and Figure 8 As shown, the right end of the hollow shaft 21 is sleeved with a first end face gear 26 which is fixedly connected concentrically, and the right end of the central shaft 23 is sleeved with a second end face gear 27 which is fixedly connected concentrically. The first end face gear 26 and the second end face gear 27 are symmetrically distributed on the left and right. A vertically distributed T-shaped plate 32 is fixedly arranged in the middle of the right side of the L-shaped side plate 31, and a vertically distributed vertical shaft 29 is rotatably inserted in the right end portion of the T-shaped plate 32. A concentrically fixed linkage gear 28 is sleeved on the top end portion of the vertical shaft 29. The linkage gear 28 is located between the first end face gear 26 and the second end face gear 27, and the linkage gear 28 is meshed and connected with the first end face gear 26 and the second end face gear 27 respectively; the linkage gear 28 can mesh and drive the first end face gear 26 and the second end face gear 27 to rotate forwardly and reversely; for example, the first end face gear 26 can drive the hollow shaft 21 and the first stirring blade 22 to rotate forwardly, and the second end face gear 27 can drive the central shaft 23 and the second stirring blade 24 to rotate reversely; The first stirring blade 22 rotating in the forward direction pushes the raw material to move in one direction, and the second stirring blade 24 rotating in the reverse direction pushes the raw material to move in the opposite direction. The two flows interweave and collide with each other, so that the raw materials of different components (such as aggregates, cementitious materials, additives, etc.) can be fully mixed in all directions, reducing the dead angle of stirring and ensuring the uniformity of the paste as a whole; Through the full stirring of the stirring blades rotating in both directions, the particles in the obtained paste are distributed more evenly and the interaction force between the particles is more balanced, which effectively reduces the segregation phenomenon that may occur during the stirring, transportation and filling process, and ensures the consistency and stability of the paste in the whole process; In addition, the design of two stirring blades rotating one forward and one counter-rotating can make more rational use of the power of the motor and make the energy distribution during the stirring process more uniform. Compared with single-blade stirring or same-direction blade stirring, this design may reduce overall energy consumption, improve energy utilization efficiency and reduce production costs while achieving the same stirring effect.

[0022] In the specific implementation process, Figure 7 and Figure 8 As shown, an arc-shaped rack 35 is fixedly arranged in the middle of the bottom surface of the mixing tank 14, and a reciprocating shaft 36 is rotatably inserted between the bottoms of a pair of fixed side plates 13 and is distributed therethrough. A concentrically fixed widening gear 37 is sleeved in the middle of the reciprocating shaft 36, and the widening gear 37 is meshedly connected with the arc-shaped rack 35, and a concentrically fixed toggle gear 38 is sleeved on the right side of the reciprocating shaft 36; the widening gear 37 can mesh and drive the arc-shaped rack 35, the mixing tank 14, and a pair of fixed snap rings 17 to reciprocate along the circular through holes on the pair of fixed side plates 13; A vertically distributed horizontal shaft 33 is rotatably inserted at the bottom of the T-shaped plate 32, a first bevel gear 34 is sleeved on the right end of the horizontal shaft 33, and a second bevel gear 30 is sleeved on the bottom end of the vertical shaft 29, and the first bevel gear 34 is meshed with the second bevel gear 30; the first bevel gear 34 can mesh and drive the second bevel gear 30, the vertical shaft 29, and the linkage gear 28 to rotate; the left end of the horizontal shaft 33 rotates through the L-shaped side plate 31 and the fixed side plate 13 on the right side, and the left end of the horizontal shaft 33 is sleeved with a first gear 39 that is concentrically fixed; A square through hole is provided at the bottom of the fixed side plate 13 on the right side, and a second motor 41 is installed inside the square through hole. A concentrically fixed second gear 42 is sleeved on the motor shaft end of the second motor 41, and the second gear 42 is meshed and connected with the first gear 39; the motor shaft of the second motor 41 can drive the second gear 42 to rotate synchronously, and the second gear 42 can mesh and drive the first gear 39, the horizontal shaft 33, and the first bevel gear 34 to rotate; A plurality of first pins 40 are fixedly disposed on the left side of the first gear 39, and a plurality of second pins 43 are fixedly disposed on the left side of the second gear 42, and the plurality of first pins 40 and the plurality of second pins 43 are alternately meshed with the toggle gear 38; the first pins 40 on the first gear 39 and the second pins 43 on the second gear 42 are alternately meshed with the toggle gear 38, and can drive the toggle gear 38, the reciprocating shaft 36, and the widening gear 37 to reciprocate; The reciprocating rotation of the stirring tank 14 can achieve more complete and three-dimensional mixing of the raw materials under the action of forces in different directions, improve the mixing uniformity and efficiency, and better adjust the rheological properties of the paste to make it more in line with the requirements of mining filling; By adjusting the reciprocating rotation frequency of the stirring tank 14 and the rotation speed of the blades, a good stirring effect can be achieved, the impact force of the raw materials can be dispersed, the wear of the stirring tank 14 and the stirring blades can be reduced, the service life of the device can be extended, and it can adapt to different raw materials, thereby improving the versatility and adaptability of the device.

[0023] Embodiment 2: Based on Embodiment 1, this embodiment also includes the following contents: like Figure 4 As shown, a pair of symmetrically distributed fixed ear seats 4 are fixed at the two corners of the left side wall of the inclined plate 3, and a triangular ear seat 6 is fixed on the top surface of each T-shaped slide plate 5, and the top end of each triangular ear seat 6 is movably hinged to the outer end of the fixed ear seat 4 on the same side; A pair of symmetrically distributed L-shaped connecting rods 8 are hingedly provided in the middle of the front and rear side walls of the tilting plate 3, and a pair of symmetrically distributed U-shaped ear seats 7 are fixedly provided at the two right corners of the top surface of the bottom plate 1, and the opening of each U-shaped ear seat 7 is movably hinged to the bottom end of the L-shaped connecting rod 8 on the same side; under the hinged action of the triangular ear seat 6 and the fixed ear seat 4, the tilting plate 3 can be driven to tilt and slide along the L-shaped connecting rod 8, thereby driving the tilting plate 3 and the mixing tank 14 to tilt to a suitable angle; A pair of symmetrically distributed single-ear seats 9 are fixed on the top surface of the bottom plate 1, and a threaded hole is opened in the middle of each T-shaped slide plate 5. A screw 10 is screwed and inserted into the interior of each threaded hole. The right end of each screw 10 rotates through the single-ear seat 9 on the same side and is sleeved with a concentrically fixed driven sprocket; under the action of the screw 10 and the threaded hole on the T-shaped slide plate 5, the T-shaped slide plate 5 can be driven to slide along the U-shaped channel steel 2; A first motor 11 is fixedly arranged on the top surface of the bottom plate 1, and a pair of concentrically fixed driving sprockets are sleeved on the motor shaft end of the first motor 11, and each driving sprocket is transmission-connected with a corresponding driven sprocket through a chain belt 12; the motor shaft of the first motor 11 can drive the driving sprocket to rotate synchronously, and the driving sprocket can drive the driven sprocket and the lead screw 10 to rotate synchronously through the chain belt 12; After the inclined plate 3 and the stirring tank 14 are tilted and adjusted to a suitable angle, the inclined stirring tank 14 changes the gravity distribution of the raw materials in the stirring tank 14, prompting the raw materials to flow along the inclined direction under the action of their own gravity. With the stirring of the stirring blades, the movement trajectory of the raw materials is more complicated, and the chances of the raw materials in different parts interlacing and colliding with each other increase, thereby accelerating the mixing of the components and improving the mixing uniformity of the paste; The inclined mixing tank 14 allows the raw materials to have a certain self-flow tendency under the action of gravity, which reduces the workload of the mixing blades to a certain extent; the mixing blades do not need to completely overcome the resistance caused by the static state and high viscosity of the raw materials, thereby reducing the energy consumption of the motor, extending the service life of the device, and reducing the maintenance cost of the device.

[0024] Different mining filling scenarios have different requirements for the performance and filling methods of the paste. By adjusting the angles of the inclined plate 3 and the mixing tank 14, the mixing degree, fluidity and other properties of the paste can be adjusted according to actual conditions to better adapt to various complex underground filling environments and ensure the filling quality and effect.

[0025] Embodiment 3: Based on Embodiment 2, this embodiment also includes the following contents: like Fig.10 As shown, a plurality of evenly distributed connecting ear seats 44 are fixedly arranged on the left side of the outer ring surface of the discharge port 16, and a driven shaft 45 distributed therethrough is rotatably inserted into the outer end of each connecting ear seat 44, and a sector baffle 47 is fixedly arranged on the left end of each driven shaft 45, and the sector baffles 47 are closed to form a disc shape, and a concentrically fixed driven gear 46 is sleeved on the right end of each driven shaft 45; the sector baffles 47 can be opened to a certain extent along the discharge port 16, and the paste in the mixing tank 14 is discharged along the opening; The outer ring surface of the discharge port 16 is sleeved with a concentric fixed positioning snap ring 48, and an outer gear ring 49 is rotatably engaged on the outer ring surface of the positioning snap ring 48. The outer gear ring 49 is meshed and connected with a plurality of driven gears 46 in sequence; the driven gear 46 can mesh and drive the outer gear ring 49 to rotate along the positioning snap ring 48, and the outer gear ring 49 can mesh and drive the remaining driven gears 46, the driven shaft 45, and the fan-shaped baffle 47 to rotate; A fixed frame 50 is fixedly arranged on the top of the outer ring surface of the discharge port 16, and a third motor 51 is installed in the fixed frame 50. A third gear 52 is concentrically fixedly arranged on the end of the motor shaft of the third motor 51, and the third gear 52 is meshedly connected with the corresponding driven gear 46; the motor shaft of the third motor 51 can drive the third gear 52 to rotate synchronously, and the meshing of the third gear 52 can drive the corresponding driven gear 46 to rotate in the opposite direction; A plurality of fan-shaped baffles 47 are arranged in a circular shape around the discharge port 16, and a certain opening is opened to discharge the paste stirred in the mixing tank 14. By adjusting the size of the opening opened by the fan-shaped baffles 47, the discharge amount of the paste can be accurately controlled. The circularly arranged fan-shaped baffles 47 can make the paste receive a relatively uniform resistance when being discharged, thereby ensuring the stability of the discharge speed. The stable discharge speed is helpful for the subsequent conveying and filling operations, making the entire filling process smoother and reducing equipment failures or filling quality problems caused by fluctuations in the discharge speed. The fan-shaped baffle 47 plays a certain blocking and combing role on the paste during the discharge process, avoiding the segregation of the paste due to excessive flow rate or uneven force during discharge. This helps to maintain the uniform distribution of various components in the paste, ensure the stability of the quality of the paste filled into the well, and improve the strength and stability of the filling body.

[0026] Specifically, the working principle and operation method of the present invention are as follows: Step 1: Under the driving action of the first motor 11, the motor shaft of the first motor 11 drives the driving sprocket to rotate synchronously, and the driving sprocket drives the driven sprocket and the lead screw 10 to rotate synchronously through the chain belt 12. Under the action of the lead screw 10 and the threaded hole on the T-shaped slide plate 5, the T-shaped slide plate 5 is driven to slide along the U-shaped channel steel 2, and under the hinged action of the triangular ear seat 6 and the fixed ear seat 4, the inclined plate 3 is driven to slide along the L-shaped connecting rod 8, and the inclined plate 3 and the mixing tank 14 are driven to tilt to a suitable angle; the preferred inclination angle here, that is, the angle between the inclined plate 3 and the horizontal plane is 13.5°; Step 2: Raw materials such as coal gangue, cement and water are injected into the mixing tank 14 through the raw material conveying pipe 20. Under the driving action of the second motor 41, the motor shaft of the second motor 41 drives the second gear 42 to rotate synchronously, and the second gear 42 meshes and drives the first gear 39, the horizontal shaft 33 and the first bevel gear 34 to rotate; The first pin 40 on the first gear 39 and the second pin 43 on the second gear 42 are alternately meshed with the toggle gear 38 to drive the toggle gear 38, the reciprocating shaft 36, and the widening gear 37 to reciprocate, and the widening gear 37 is then meshed to drive the arc rack 35, the mixing tank 14, and a pair of fixed snap rings 17 to reciprocate along the circular through holes on the pair of fixed side plates 13; Step 3: The first bevel gear 34 meshes to drive the second bevel gear 30, the vertical shaft 29, and the linkage gear 28 to rotate. The linkage gear 28 meshes to drive the first end face gear 26 and the second end face gear 27 to rotate forward and reversely. The first end face gear 26 drives the hollow shaft 21 and the first stirring blade 22 to rotate forward, and the second end face gear 27 drives the central shaft 23 and the second stirring blade 24 to rotate reversely.
