Description

Technical Field

[0001] The invention relates to the technical field of soil-rock separation, in particular to a soil-rock separation device and a separation method thereof. Background Art

[0002] In the fields of engineering construction, mining, etc., soil and rock separation is an important work link. At present, the common methods of soil and rock separation mainly include manual sorting, mechanical screening, etc.

[0003] Manual sorting is inefficient, labor-intensive, and difficult to meet the needs of large-scale soil-rock separation. Traditional mechanical screening devices have some shortcomings during use.

[0004] On the one hand, the existing soil-rock separation equipment often simply performs screening operations when separating soil and rocks, and the drying of soil and rocks is not sufficient. The moisture in the soil and rocks will affect the separation effect, making the soil easy to stick to the rocks, increasing the difficulty of separation. At the same time, the soil and rocks that are not fully dried are easy to clog the screen during the screening process, reducing the separation efficiency.

[0005] On the other hand, the traditional equipment has limited stirring effect when mixing soil and rocks, and cannot fully turn the soil and rocks, resulting in uneven heating of the soil and rocks, affecting the drying speed and effect. Moreover, large-particle stones are easily accumulated on the screen during the separation process, hindering the passage of soil, further affecting the efficiency and quality of soil-rock separation.

[0006] In addition, the high-temperature hot air generated by the existing soil-rock separation device when heating and drying the soil and rocks is usually not effectively utilized, resulting in energy waste. In addition, there is a lack of treatment measures for water vapor in the high-temperature hot air, and the presence of water vapor will also affect the drying effect of the soil and rocks.

The rotation of the stirring tube drives the spiral stirring net and the lever to rotate to stir the internal soil and stone, and cooperate with the heating box to quickly heat the soil and stone;

[0021] Step 3: The hot gas circulation type absorbs water vapor in the high-temperature hot gas through the water absorption filter.

[0023] The present invention provides a soil-rock separation device and a separation method thereof. Compared with the prior art, it has the following beneficial effects:

[0024] 1. The soil-rock separation device and the separation method thereof can turn over the soil and rocks inside by rotating the spiral stirring net, and the turned soil and rocks can accelerate the drying efficiency. When the stirring tube rotates, the first crown gear can be driven to rotate forward, and the second crown gear can be driven to rotate synchronously by the forward rotation of the first crown gear. The rotation of the second crown gear can drive the lower cross bar and the lower lever to rotate synchronously around the stirring tube, so that the lever can be driven on the outer side of the spiral stirring net to further improve the turning effect of the soil and rocks, thereby improving the drying effect.

[0025] 2. The soil-rock separation device and separation method thereof, high-temperature hot air enters the power box through the auxiliary cylinder and the connecting pipe, and enters the connecting box after passing over the piston plate. When the hot air passes through the auxiliary cylinder, the water vapor inside the hot air is absorbed by the water absorption filter. After the dry hot air enters the connecting box, it enters the stirring tube through the connecting groove and is discharged through the air outlet. When the high-speed gas is blown into the soil and rock, the soil and rock can be blown into a loose state. The loose soil and rock greatly increase the heating area of ​​the soil and rock, so that the soil and rock are better and more efficient when heated, and the loose soil and rock can make the filtering speed faster.

[0026] 3. The soil-rock separation device and the separation method thereof can ensure that part of the soil falls through the holes in the process of guiding the stones inside the soil and rock upward through the holes above the spiral stirring net, and the stones continue to move upward through the spiral stirring net, thereby realizing the upward and downward circulation of the stones inside the soil and rock, reducing the number of stones stacked on the filter net, thereby realizing the upward guidance of the stones accumulated at the bottom, and reducing the influence of the stone accumulation on the soil-rock separation.

[0027] 4. The soil-rock separation device and the separation method thereof drive the first crown gear to reverse when the stirring tube is reversed. After the first crown gear is reversed, it no longer drives the second crown gear to rotate but drives the second crown gear to move downward. When moving downward, the reset spring is compressed. After compression, the reset spring drives the second crown gear to reset, thereby realizing that the rotation of the first crown gear drives the second crown gear to move up and down reciprocatingly, thereby driving the cross bar and the lever to move up and down. By moving the lever up and down and knocking on the filter screen, the separation can be accelerated while preventing the filter screen from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Reference Figures 1 to 8 In one aspect of the present embodiment, a cross 34 is fixedly installed between the connecting box 31 and the power box 32, a bidirectional screw 35 is rotatably connected between the cross 34 and the right inner wall of the power box 32, a piston plate 36 is screwed on the outer side of the bidirectional screw 35, the cross section of the piston plate 36 is elliptical, the outer wall of the piston plate 36 is completely fitted to the inner wall of the power box 32, a first one-way valve is embedded in the inner wall of the piston plate 36, a second one-way valve is fixedly installed at the connection between the connecting pipe 33 and the power box 32, the first one-way valve is connected in a direction from right to left, and the second one-way valve is connected in a direction from top to bottom. No threads are set on the left and right ends of the bidirectional screw 35, the left end of the bidirectional screw 35 is movable through the inside of the cross 34, a fourth bevel gear 37 is fixedly installed on the left end of the bidirectional screw 35, and the fourth bevel gear 37 is located inside the connecting box 31, and a fifth bevel gear 316 is fixedly installed on the outside of the stirring pipe 41 and located inside the connecting box 31, and the fifth bevel gear 316 and the fourth bevel gear 37 are meshed with each other.

[0045] The right side of the bracket 21 is rotatably connected to a traverse rod 25, and a second bevel gear 26 is fixedly installed on the right side end of the traverse rod 25, and the second bevel gear 26 and the third bevel gear 27 are meshed with each other. The first bevel gear 24 is located above the second bevel gear 26, and an internal groove 211 is opened inside the adjusting rotating rod 28, and the internal groove 211 is located below the square block 210. A water absorption filter 311 is slidably connected inside the auxiliary cylinder 310, and a support spring 312 is fixedly installed between the water absorption filter 311 and the bottom of the auxiliary cylinder 310. A vertical movable rod 313 is fixedly installed on the top of the auxiliary cylinder 310, and the top of the vertical movable rod 313 moves through the top of the auxiliary cylinder 310. A magnet block 314 is fixedly installed on the top of the auxiliary cylinder 310, and a traverse moving rod 315 is fixedly installed on the side of the magnet block 314. The moving shaft 29 is rotatably connected to the inside of the front of the traverse moving rod 315, and the top wall of the auxiliary cylinder 310 is made of metal iron.

[0046] In this embodiment, when the soil and stone are stirred and dried, a large amount of high-temperature hot air will be generated during the drying process. At this time, the stirring tube 41 can drive the fifth bevel gear 316 to rotate when it rotates, and the fourth bevel gear 37 is driven to rotate by the fifth bevel gear 316. The bidirectional screw 35 is driven to rotate by the rotation of the fourth bevel gear 37. The rotation of the bidirectional screw 35 can drive the piston plate 36 to move back and forth left and right. The reciprocating movement of the piston plate 36 and the one-way valve can absorb the gas from the right side of the piston plate 36 and squeeze it to the left side of the piston plate 36, so that the high-temperature hot air can be absorbed by the bottom of the auxiliary cylinder 310, and the high-temperature hot air passes through The auxiliary cylinder 310 and the connecting pipe 33 enter the power box 32, and then pass through the piston plate 36 to enter the connecting box 31. When the hot air passes through the auxiliary cylinder 310, the water vapor inside the hot air is absorbed by the water absorption filter 311. After the dry hot air enters the connecting box 31, it enters the stirring pipe 41 through the connecting groove 38 and is discharged through the air outlet 39. When the high-speed gas is blown into the soil and rocks, the soil and rocks can be blown into a loose state. The loose soil and rocks greatly increase the heating area of ​​the soil and rocks, so that the soil and rocks are better and more efficient when heated, and the loose soil and rocks can make the filtering speed faster;

[0047] The water content inside the soil and stone is certain. When the soil and stone are dried to a certain degree, the soil and stone are no longer sticky. At this time, the water absorption filter 311 absorbs enough water. After absorbing water, the water absorption filter 311 will move downward under the action of gravity, and the support spring 312 will be compressed. The vertical movable rod 313 moves downward synchronously with the water absorption filter 311, and the magnet block 314 moves downward synchronously. After the magnet block 314 moves downward, the distance between the magnet block 314 and the top of the auxiliary cylinder 310 becomes closer and closer, and the attraction between the two becomes greater. When the water absorption filter 311 absorbs enough water vapor, the absorption between the magnet block 314 and the auxiliary cylinder 310 cannot be supported by the support spring 312. The magnet block 314 will quickly approach and be adsorbed on the top of the auxiliary cylinder 310. At this time, the moisture content of the soil and rocks is just not enough to stick to each other. When the magnet block 314 moves downward, the horizontal moving rod 315 drives the moving shaft 29 to move downward synchronously. The downward movement of the moving shaft 29 can move the square block 210 to the inside of the internal groove 211, and mesh the first bevel gear 24 with the second bevel gear 26. At this time, the rotation of the moving shaft 29 can no longer directly drive the adjustment rod 28 to rotate. At this time, when the motor 22 drives the first bevel gear 24 to rotate, it will first drive the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 will then drive the third bevel gear 27 to rotate. The first bevel gear 24 and the third bevel gear 27 rotate in opposite directions, so that the rotation direction of the adjusting lever 28 is opposite to that before, so that after the soil and stone are dried to a certain extent, the adjusting lever 28 and the stirring tube 41 will switch the rotation direction and become reverse. When the stirring tube 41 reverses, it drives the spiral stirring net 42 to rotate. At this time, the rotation of the spiral stirring net 42 can transport the soil and stone upward along the spiral stirring net 42, and fall from the outside after being lifted to the top, thereby forming a soil and stone vortex inside, thereby driving the internal soil and stone to be turned over, thereby greatly improving the heating uniformity of the soil and stone inside and outside, and because the soil and stone particles are large, when the soil and stone are turned over When the filter 5 is filtered, large-particle stones tend to accumulate on the filter screen 5 under the action of gravity. The stones accumulated on the filter screen 5 will affect the soil passing through the filter screen 5. At this time, the soil and stones can be guided upward by rotating the spiral stirring net 42. When guiding upward, the holes above the spiral stirring net 42 can ensure that part of the soil falls through the holes during the upward guidance of the stones inside the soil and stones. The stones continue to move upward through the spiral stirring net 42, realizing the upward and downward circulation of the stones inside the soil and stones, reducing the number of stones stacked on the filter screen 5, thereby realizing the upward guidance of the stones accumulated at the bottom, reducing the influence of the stone accumulation on the separation of soil and rocks;

[0048] When the stirring tube 41 is reversed, the first crown gear 48 is driven to reverse. After the first crown gear 48 is reversed, it no longer drives the second crown gear 49 to rotate but drives the second crown gear 49 to move downward. When moving downward, the return spring 45 is compressed. After compression, the return spring 45 drives the second crown gear 49 to reset, thereby realizing that the first crown gear 48 rotates to drive the second crown gear 49 to move up and down reciprocatingly, thereby driving the cross bar 43 and the lever 44 to move up and down. By moving the lever 44 up and down and knocking the filter screen 5, the separation can be accelerated while preventing the filter screen from being blocked.

[0049] The separated soil passes through the filter screen 5 and is guided through the slope 9, and is collected by opening the box door 7. A sealed door that can be opened and closed is provided on the side of the heating box 1. The stones on the filter screen 5 can be processed by opening the sealed door, and a pressure relief valve is provided on the side wall of the heating box 1 to prevent the internal air pressure from being too high.

[0050] This embodiment also discloses a separation method of the soil-rock separation device, comprising the following steps:

[0051] Step 1: Start the motor 22 to drive the adjusting rod 28 to rotate, and the adjusting rod 28 drives the stirring tube 41 to rotate, and the stirring tube 41 drives the spiral stirring net 42 and the lever 44 to rotate to stir the soil and rocks inside, and cooperate with the heating box 1 to quickly heat the soil and rocks;

[0052] Step 2: When the soil and stone are heated, the high-temperature gas generated by the heating is passed into the stirring tube 41 through the reciprocating movement of the piston plate 36 and then re-entered into the soil and stone through the gas outlet 39, further accelerating the drying speed;

[0053] Step 3: The hot gas circulates to absorb water vapor in the high-temperature hot gas through the water absorption filter 311. After absorbing to a certain extent, the water absorption filter 311 moves downward, and the moving shaft 29 and the first bevel gear 24 move downward, thereby changing the rotation direction of the adjusting lever 28 and the stirring tube 41;

[0054] Step 4: After the direction of the stirring tube 41 is changed, the spiral stirring net 42 can flip the soil and rocks upward, and transport the stones accumulated on the filter net 5 up and down, and knock the filter net 5 through the lever 44 to ensure rapid screening of the soil and rocks.

[0056] Working principle: when separating soil and rocks, the soil and rocks are added into the heating box 1 through the upper hopper 10. After being added into the heating box 1, the upper hopper 10 is sealed through the hopper cover 11. Then, the internal soil and rocks are heated and dried by starting the heating box 1. During drying, the telescopic shaft 23 is driven to rotate by the starting motor 22, and the first bevel gear 24 is driven to rotate by the rotation of the telescopic shaft 23. The mobile shaft 29 is driven to rotate by the rotation of the first bevel gear 24. The internal square block 210 is driven to rotate by the rotation of the mobile shaft 29. The outer adjusting rod 28 can be driven to rotate by the square block 210. The lower stirring tube 41 can be driven to rotate forward by the rotation of the adjusting rod 28. The outer spiral stirring tube 41 can be driven to rotate by the rotation of the stirring tube 41. The mixing net 42 rotates, and the soil and rocks inside can be turned over by the rotation of the spiral mixing net 42. The turned soil and rocks can speed up the drying efficiency, and when the mixing tube 41 rotates, the first crown gear 48 can be driven to rotate forward, and the first crown gear 48 can be driven to rotate synchronously by the forward rotation of the second crown gear 49. The rotation of the second crown gear 49 can drive the lower cross bar 43 and the lower lever 44 to rotate synchronously around the mixing tube 41, so that the lever 44 can be moved on the outside of the spiral mixing net 42, and the turning effect of the soil and rocks can be further improved by the lever 44, thereby improving the drying effect; the circular slide rail 47 and the slider 46 support the reset spring 45, the reset spring 45 supports the cross bar 43, and the cross bar 4 3 supports the second crown gear 49. When supporting the second crown gear 49, the slider 46 slides on the circular slide rail 47 to ensure that the second crown gear 49 is supported without affecting its rotation. When the soil and stone are stirred and dried, a large amount of high-temperature hot air will be generated during the drying process. At this time, the stirring tube 41 can drive the fifth bevel gear 316 to rotate when rotating, and the fourth bevel gear 37 is driven to rotate by the fifth bevel gear 316. The bidirectional screw 35 is driven to rotate by the rotation of the fourth bevel gear 37. The piston plate 36 can be driven to reciprocate left and right by the rotation of the bidirectional screw 35. The reciprocating movement of the piston plate 36 and the one-way valve can absorb gas from the right side of the piston plate 36 and squeeze it to the piston plate 3 6, so that the high-temperature hot air can be absorbed through the bottom of the auxiliary cylinder 310, and the high-temperature hot air enters the power box 32 through the auxiliary cylinder 310 and the connecting pipe 33, and enters the connecting box 31 after crossing the piston plate 36. When the hot air passes through the auxiliary cylinder 310, the water vapor inside the hot air is absorbed by the water absorption filter 311, and the dry hot air enters the connecting box 31 and enters the stirring pipe 41 through the connecting groove 38, and then is discharged through the air outlet 39. When the high-speed gas is blown into the soil and stone, the soil and stone can be blown into a loose state. The loose soil and stone greatly increases the heating area of ​​the soil and stone, so that the soil and stone have a better effect and higher efficiency when heated, and the loose soil and stone can make the filtering speed faster;

[0057] The water content inside the soil and stone is certain. When the soil and stone are dried to a certain degree, the soil and stone are no longer sticky. At this time, the water absorption filter 311 absorbs enough water. After absorbing water, the water absorption filter 311 will move downward under the action of gravity, and the support spring 312 will be compressed. The vertical movable rod 313 moves downward synchronously with the water absorption filter 311, and the magnet block 314 moves downward synchronously. After the magnet block 314 moves downward, the distance between the magnet block 314 and the top of the auxiliary cylinder 310 becomes closer and closer, and the attraction between the two becomes greater. When the water absorption filter 311 absorbs enough water vapor, the absorption between the magnet block 314 and the auxiliary cylinder 310 cannot be supported by the support spring 312. The magnet block 314 will quickly approach and be adsorbed on the top of the auxiliary cylinder 310. At this time, the moisture content of the soil and rocks is just not enough to stick to each other. When the magnet block 314 moves downward, the horizontal moving rod 315 drives the moving shaft 29 to move downward synchronously. The downward movement of the moving shaft 29 can move the square block 210 to the inside of the internal groove 211, and mesh the first bevel gear 24 with the second bevel gear 26. At this time, the rotation of the moving shaft 29 can no longer directly drive the adjustment rod 28 to rotate. At this time, when the motor 22 drives the first bevel gear 24 to rotate, it will first drive the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 will then drive the third bevel gear 27 to rotate. The first bevel gear 24 and the third bevel gear 27 rotate in opposite directions, so that the rotation direction of the adjusting lever 28 is opposite to that before, so that after the soil and stone are dried to a certain extent, the adjusting lever 28 and the stirring tube 41 will switch the rotation direction and become reverse. When the stirring tube 41 reverses, it drives the spiral stirring net 42 to rotate. At this time, the rotation of the spiral stirring net 42 can transport the soil and stone upward along the spiral stirring net 42, and fall from the outside after being lifted to the top, thereby forming a soil and stone vortex inside, thereby driving the internal soil and stone to be turned over, thereby greatly improving the heating uniformity of the soil and stone inside and outside, and because the soil and stone particles are large, when the soil and stone are turned over When the filter 5 is filtered, large-particle stones tend to accumulate on the filter screen 5 under the action of gravity. The stones accumulated on the filter screen 5 will affect the soil passing through the filter screen 5. At this time, the soil and stones can be guided upward by rotating the spiral stirring net 42. When guiding upward, the holes above the spiral stirring net 42 can ensure that part of the soil falls through the holes during the upward guidance of the stones inside the soil and stones. The stones continue to move upward through the spiral stirring net 42, realizing the upward and downward circulation of the stones inside the soil and stones, reducing the number of stones stacked on the filter screen 5, thereby realizing the upward guidance of the stones accumulated at the bottom, reducing the influence of the stone accumulation on the separation of soil and rocks;

[0058] When the stirring tube 41 is reversed, the first crown gear 48 is driven to reverse. After the first crown gear 48 is reversed, it no longer drives the second crown gear 49 to rotate but drives the second crown gear 49 to move downward. When moving downward, the return spring 45 is compressed. After compression, the return spring 45 drives the second crown gear 49 to reset, thereby realizing that the first crown gear 48 rotates to drive the second crown gear 49 to move up and down reciprocatingly, thereby driving the cross bar 43 and the lever 44 to move up and down. By moving the lever 44 up and down and knocking the filter screen 5, the separation can be accelerated while preventing the filter screen from being blocked.

[0059] The separated soil passes through the filter screen 5 and is guided through the slope 9, and is collected by opening the box door 7. A sealed door that can be opened and closed is provided on the side of the heating box 1. The stones on the filter screen 5 can be processed by opening the sealed door, and a pressure relief valve is provided on the side wall of the heating box 1 to prevent the internal air pressure from being too high.
