Description

Technical Field

[0001] The present invention belongs to the technical field of air separation equipment, and specifically relates to a stone powder air separation device and method for all-dry production. Background Art

[0002] Machine-made sand, also known as artificial sand, is a granular sand and gravel material obtained by crushing, screening, and washing large rocks (usually natural stones) through mechanical equipment (such as crushers, sand making machines, etc.). During some engineering construction processes, machine-made sand is used to replace natural river sand. However, machine-made sand contains a certain amount of stone powder, which will affect the construction quality. Therefore, air separation and dust removal equipment is needed to remove the stone powder in the machine-made sand. The stone powder air separation device in all-dry production is a device that separates materials with different particle sizes in stone powder through air flow. It is mainly used for stone powder treatment in industries such as ores, quartz, and sand and gravel, and can effectively remove impurities in the powder and improve the purity of the product. The air separation device controls the air flow velocity, so that lighter substances (such as fine stone powder) are carried away by the air flow, while heavier substances are left in the equipment to complete the separation of materials.

[0003] Patent application CN212856626U discloses a diversion air separation system based on adjusting the stone powder content. The key points of its technical solution are: including a dust filter and an induced draft fan connected to the dust filter, and also including a diversion air separator. The diversion air separator includes an air separation chamber, a buffer device, and a diversion component; an inlet and an outlet are respectively provided at the top and bottom of the air separation chamber; the buffer device is fixed on the inner wall of the air separation chamber to be used for dispersing and separating the mixed stone materials entering the air separation chamber from the inlet, and the diversion component is fixed on the inner wall of the air separation chamber to be used for guiding the dispersed stone materials to the outlet. An air inlet connected to the dust filter is provided on the side of the air separation chamber to be used for sending the dispersed stone powder into the dust filter through the air inlet.

[0004] However, the above technologies often have the following defects: Although the above technologies slow down the falling speed of the stone materials through the buffer device and the diversion component so that the stone powder in the stone materials can be fully separated, the above technologies only perform air separation on the stone materials once. Stones of different sizes are mixed together, which is likely to cause mutual blockage between the stones, and part of the stone powder attached to the surface of the stones is difficult to be removed, resulting in low efficiency of stone powder air separation. Therefore, the present invention provides a stone powder air separation device and method for all-dry production. Summary of the Invention

Open the cover plate, release the steel cable, so that the side of the material bucket with the cover plate is tilted upwards, load the machine-made sand into the interior of the material bucket, close the cover plate, and then wind up the steel cable to keep the material bucket horizontal;

[0021] S2. Start the motor, the motor drives the gear to rotate, and then drives the toothed ring, the material bucket and the baffle to rotate. At the same time, introduce air into the interior of the material bucket from the air inlet pipe and discharge it from the other end air outlet pipe;

[0022] S3. When the baffle moves to the lowest position, the sealing plate closes the opening of the storage box under the influence of gravity.

The air inlet pipe is connected to the fan through a hose, and the air outlet pipe is connected to the stone powder collection box through a connecting pipe. Air is introduced into the interior of the material bucket from the air inlet pipe and discharged from the other end air outlet pipe.

Detailed implementation manners

[0042] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0043] Example 1: As Figures 1 to 9 shown, a stone powder air separation device for all-dry production according to an embodiment of the present invention includes:

[0044] A material barrel 1, one end of the material barrel 1 is a closed structure, and the other end is rotatably installed with a cover plate 3, and an air inlet pipe 4 is rotatably installed in the middle of the cover plate 3, and an air outlet pipe 5 is rotatably installed in the middle of the closed end of the material barrel 1;

[0045] A suspension assembly, the suspension assembly includes a suspension bracket 2 and a support frame 6, the support frame 6 includes circular rings 61 symmetrically sleeved at both ends of the material barrel 1, and a plurality of rollers 62 are evenly installed on the joint surface between the circular rings 61 and the material barrel 1, and both sides of the support frame 6 are fixed below the suspension bracket 2;

[0046] A drive assembly 7, the drive assembly 7 includes a motor 71 fixed on the outer side of the material barrel 1, a toothed ring 73 is fixed on the outer wall of the material barrel 1, a gear 72 is fixed on the output shaft of the motor 71, and the gear 72 meshes with the toothed ring 73;

[0047] A baffle 9, the baffle 9 is axially fixed on the inner wall of the material barrel 1;

[0048] During operation, the cover plate 3 is opened, and the manufactured sand is loaded into the interior of the material barrel 1. The motor 71 is started, and the motor 71 drives the gear 72 to rotate, thereby driving the gear ring 73, the material barrel 1, and the baffle 9 to rotate. The air inlet pipe 4 is connected to the blower through a hose, and the air outlet pipe 5 is connected to the stone powder collection box through a connecting pipe. Air is introduced into the interior of the material barrel 1 from the air inlet pipe 4 and discharged from the other end air outlet pipe 5. The baffle 9 rotates with the material barrel 1, and the manufactured sand at the lowest position is repeatedly lifted to a high place and scattered by the baffle 9, so that the manufactured sand can be repeatedly subjected to air separation, and further, more stone powder in the manufactured sand can be blown out by wind, improving the air separation effect. In addition, the manufactured sand is repeatedly scattered from a high place, and multiple sand grains rub against each other repeatedly, which helps to shake off the stone powder adhering to the surface of the sand grains, further improving the stone powder air separation effect.

[0049] It further includes a material scattering assembly 10. The material scattering assembly 10 includes a storage box 101. The storage box 101 is trapezoidal in shape. Both the upper and lower sides of the storage box 101 are open. A sealing plate 102 is provided on the inner wall side of the storage box 101 away from the material barrel 1. The sealing plate 102 has magnetism and can be adsorbed on the outside of the opening of the storage box 101. Long rods 107 are symmetrically provided on both sides of the sealing plate 102. A rotating sleeve is installed between the ends of the two long rods 107. The long rods 107 slide through the side wall of the material barrel 1. An outer shell 8 is sleeved outside the material barrel 1. The outer shell 8 is fixed below the suspension bracket 2. A boss 1015 is fixed on the inner wall of the top of the outer shell 8.

[0050] During operation, when the baffle 9 moves to the lowest position, the sealing plate 102 closes the opening of the storage box 101 under the influence of gravity, and the sealing plate 102 is adsorbed at the opening position. The baffle 9 rotates with the material barrel 1, automatically loading the manufactured sand at a low place into the storage box 101. The manufactured sand is lifted to the highest position by the baffle 9 and the storage box 101. At the same time, the long rods 107 move to the highest position synchronously. The rotating sleeve at the end of the long rod 107 moves along the inclined surface to the position where the boss 1015 is closest to the material barrel 1. At this time, the boss 1015 squeezes the long rod 107, and then the sealing plate 102 is pushed open by the long rod 107. At this time, the manufactured sand inside the storage box 101 can be scattered from the highest position of the material barrel 1, so as to extend the contact time between the manufactured sand and the wind, and further improve the air separation effect.

[0051] An activity block 103 is provided on the side of the sealing plate 102. The contour of the activity block 103 is adapted to the opening of the storage box 101 away from the inner wall of the material barrel 1. The activity block 103 is slidably arranged in the opening. An activity cavity is formed between the sealing plate 102 and the activity block 103. The end of the long rod 107 slides through to the inside of the activity cavity, and a fixed block 105 is fixed on the end of the long rod 107. A first spring 106 is installed inside the activity cavity. Magnetic blocks 1014 are fixedly arranged at intervals on the inner wall of the outer shell 8. During operation, as Figure 8As shown, when the storage box 101 rotates towards the highest position, the long rod 107 first passes through the area of the magnet 1014. When the long rod 107 aligns with the magnet 1014, the magnet 1014 attracts the long rod 107. The long rod 107 pulls the movable block 103 along the opening position towards the inside of the storage box 101 through the fixed block 105, and the first spring 106 is stretched. At this time, the movable block 103 synchronously pushes the machine-made sand inside the box upward. When the long rod 107 completely passes through the magnet 1014, the movable block 103 is driven by the first spring 106 to reset. At this time, the machine-made sand inside the box moves downward. A plurality of magnets 1014 are arranged at intervals to drive the long rod 107 and the movable block 103 to reciprocate, so as to repeatedly stir the machine-made sand in the storage box 101, so that the sand grains can collide and rub against each other before the machine-made sand is scattered, which helps to shake off the stone powder attached to the surface of the sand grains and further improve the air separation effect of the stone powder.

[0052] An elastic sheet 104 is provided on the side of the movable block 103 away from the sealing plate 102. During operation, when the storage box 101 rotates to the highest position, the long rod 107 is squeezed by the convex platform 1015 to push open the sealing plate 102. At the same time, the sealing plate 102 drives the movable block 103 and the elastic sheet 104 to move down to the outside of the storage box 101. The elastic sheet 104 is made of high-elastic wear-resistant rubber. When the machine-made sand is scattered from the opening of the storage box 101, the machine-made sand first falls on the top of the elastic sheet 104, and the elastic sheet 104 rebounds the sand grains so that the sand grains below collide with the sand grains above, which can further shake off the stone powder attached to the surface of the sand grains to improve the air separation effect.

[0053] A sleeve rod 108 is fixed in the middle of the elastic sheet 104, and the sleeve rod 108 is slidably sleeved on the outside of the long rod 107. The end of the sleeve rod 108 away from the elastic sheet 104 extends through the outside of the material barrel 1, and a spring three 1016 is installed on the end. A cross bar 109 is provided in the middle of the elastic sheet 104, and the cross bar 109 is fixed on both sides of the sleeve rod 108. Mounting holes 1010 are respectively opened at both ends of the elastic sheet 104, and a limiting rod 1011 is arranged inside the mounting hole 1010. The limiting rod 1011 is set in a "冖" shape, and the two ends of the limiting rod 1011 are respectively slidably set in the sliding cavity opened at the end of the movable block 103, and a spring two 1012 is installed inside the sliding cavity to reset the limiting rod 1011; when working, when the sealing plate 102 drives the movable block 103 and the elastic sheet 104 to move downward to the outside of the storage box 101, and the sleeve rod 108 is blocked by the outer wall of the material barrel 1, and the elastic sheet 104 is pulled upward from the middle by the sleeve rod 108 and the cross bar 109. The spring three 1016 limits the movement range of the sleeve rod 108, and the two ends of the elastic sheet 104 are pulled downward by the spring two 1012, so that the middle part of the elastic sheet 104 bulges upward, so that the elastic sheet 104 is in an inverted V shape and blocks the top of the movable block 103. When the machine-made sand falls on the surface of the elastic sheet 104, the elastic sheet 104 will bounce the scattered machine-made sand to both sides, and the sand particles of different weights are ejected at different distances, so that the falling sand particles can be dispersed, thereby increasing the contact area between the machine-made sand and the wind, so as to improve the air selection effect.

[0054] The mounting hole 1010 is configured as a waist-shaped hole; during operation, when the elastic sheet 104 is pulled up from the middle, the limiting rod 1011 moves along the mounting hole 1010, so that the elastic sheet 104 is subjected to less pulling force when deformed, thereby extending the service life of the elastic sheet 104.

[0055] The two ends of the top of the suspension frame 2 are respectively fixed with lifting rings, and the lifting rings on both sides are respectively suspended from the bottom of the mounting frame by steel cables, and the mounting frame is equipped with winches for controlling the release and reeling of the steel cables on both sides; during operation, when loading, first open the cover plate 3, release the steel cable, so that the side of the material barrel 1 equipped with the cover plate 3 is tilted upward, and the machine-made sand is loaded into the material barrel 1, and the cover plate 3 is closed, and then the steel cable is reeled in to keep the material barrel 1 horizontal; after the air separation is completed, release the steel cable, so that the side of the material barrel 1 equipped with the cover plate 3 is tilted downward, open the cover plate 3, and pour out the machine-made sand left over from the air separation, thus completing one air separation work.

[0056] Telescopic rods 1013 are respectively provided on both sides of the storage box 101, and the two sides of the telescopic rods 1013 are respectively fixedly connected to the storage box 101 and the sealing plate 102; when working, the movement direction of the storage box 101 is limited by setting the telescopic rods 1013, so that the storage box 101 can be aligned with the opening position of the storage box 101.

[0057] Embodiment 2: As Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is that the boss 1015 extends from the top of the housing 8 to the side; during operation, when the elastic piece 104 is pulled up from the middle, the limiting rod 1011 moves along the mounting hole 1010, so that there is a gap between the two sides of the elastic piece 104 and the surface of the movable block 103. By extending the length of the boss 1015, when the storage box 101 passes over the highest point, the elastic piece 104 remains in the pulled state, so that the sand grains accidentally falling below the elastic piece 104 can be discharged.

[0058] As Figure 10 shown, a method for air separation of stone powder for all-dry production, which is applicable to the above-mentioned air separation device for stone powder for all-dry production, includes the following steps:

[0059] S1. Open the cover plate 3, release the steel cable, so that the side of the material bucket 1 with the cover plate 3 tilts upwards, load the machine-made sand into the interior of the material bucket 1, close the cover plate 3, and then wind up the steel cable to keep the material bucket 1 horizontal;

[0060] S2. Start the motor 71, the motor 71 drives the gear 72 to rotate, and then drives the toothed ring 73, the material bucket 1 and the baffle 9 to rotate. At the same time, introduce air from the air inlet pipe 4 into the interior of the material bucket 1 and discharge it from the other end outlet pipe 5;

[0061] S3. When the baffle 9 moves to the lowest position, the sealing plate 102 closes the opening of the storage box 101 under the influence of gravity. The baffle 9 rotates with the material bucket 1 and automatically loads the machine-made sand at the lower position into the storage box 101, and raises the machine-made sand to the highest position through the baffle 9 and the storage box 101;

[0062] S4. During the rotation of the storage box 101 towards the highest position, when the long rod 107 faces the magnet 1014, the long rod 107 is attracted by the magnet 1014, and then pulls the movable block 103 towards the interior of the storage box 101. When the long rod 107 completely passes by the magnet 1014, the movable block 103 is pulled back to its original position by the first spring 106. Through the reciprocating movement of the movable block 103, the machine-made sand inside the storage box 101 is stirred;

[0063] S5. When the storage box 101 rotates to the highest position, the long rod 107 is squeezed by the boss 1015 to push open the sealing plate 102, and the machine-made sand is scattered from the storage box 101 for air separation;

[0064] S6. The sealing plate 102 drives the movable block 103 and the elastic sheet 104 to move downward to the outside of the storage box 101. The elastic sheet 104 is pulled upward from the middle through the sleeve rod 108 and the cross bar 109, so that the elastic sheet 104 is in an inverted V shape to block the top of the movable block 103. The scattered machine-made sand is bounced to both sides by the elastic sheet 104 to increase the contact area between the machine-made sand and the wind.

[0065] S7. After the air separation is completed, the steel cable is released, so that the side of the material bucket 1 with the cover plate 3 is tilted downward, the cover plate 3 is opened, and the machine-made sand remaining after the air separation is poured out, thus completing one air separation operation.

[0066] Working principle: During loading, first open the cover plate 3, release the steel cable, so that the side of the material bucket 1 with the cover plate 3 is tilted upward, load the machine-made sand into the interior of the material bucket 1, close the cover plate 3, and then wind up the steel cable to keep the material bucket 1 horizontal; start the motor 71, the motor 71 drives the gear 72 to rotate, and then drives the gear ring 73, the material bucket 1 and the baffle 9 to rotate. The air inlet pipe 4 is connected to the fan through a hose, and the air outlet pipe 5 is connected to the stone powder collection box through a connecting pipe. Wind is introduced into the interior of the material bucket 1 from the air inlet pipe 4 and discharged from the other end air outlet pipe 5. The baffle 9 rotates with the material bucket 1, and the baffle 9 repeatedly lifts the machine-made sand at the lowest position to a high place and scatters it, so as to be able to repeatedly perform air separation on the machine-made sand, and thus more stone powder in the machine-made sand can be blown out by the wind, improving the air separation effect;

[0067] When the baffle 9 moves to the lowest position, the sealing plate 102 closes the opening of the storage box 101 under the influence of gravity, and the sealing plate 102 adsorbs at the opening position. The baffle 9 rotates with the material bucket 1, and automatically loads the machine-made sand at a low place into the storage box 101. The baffle 9 and the storage box 101 lift the machine-made sand to the highest position. When the storage box 101 rotates towards the highest position, the long rod 107 first passes through the area of the magnet 1014. When the long rod 107 is aligned with the magnet 1014, the long rod 107 is attracted by the magnet 1014, and the long rod 107 pulls the movable block 103 along the opening position and moves into the storage box 101 through the fixed block 105. The first spring 106 is stretched. At this time, the movable block 103 synchronously pushes the machine-made sand in the box upward. When the long rod 107 completely passes through the magnet 1014, the movable block 103 is driven by the first spring 106 to reset. At this time, the machine-made sand in the box moves downward. A plurality of magnets 1014 are arranged at intervals, so as to drive the long rod 107 and the movable block 103 to reciprocate, and thus the machine-made sand in the storage box 101 can be repeatedly stirred, so that the sand grains can collide and rub against each other before the machine-made sand is scattered, which helps to shake off the stone powder attached to the surface of the sand grains and further improves the stone powder air separation effect;

[0068] When the storage box 101 moves towards the highest position, the long rod 107 moves synchronously to the highest position at the same time. The rotating sleeve on the end of the long rod 107 moves along the inclined surface to the position where the boss 1015 is closest to the material barrel 1. At this time, the long rod 107 is extruded by the boss 1015, and then the sealing plate 102 is pushed open by the long rod 107. At this time, the manufactured sand inside the storage box 101 can be scattered from the highest position of the material barrel 1, so as to extend the contact time between the manufactured sand and the wind, and then improve the air separation effect;

[0069] When the sealing plate 102 drives the movable block 103 and the elastic sheet 104 to move down to the outside of the storage box 101, the sleeve rod 108 is blocked by the outer wall of the material barrel 1. The elastic sheet 104 is pulled to move relatively upward from the middle through the sleeve rod 108 and the cross rod 109, and the two ends of the elastic sheet 104 are pulled downward by the second spring 1012, so that the middle part of the elastic sheet 104 bulges upward, making the elastic sheet 104 form an inverted V shape to block the top of the movable block 103. When the manufactured sand falls on the surface of the elastic sheet 104, the scattered manufactured sand is bounced to both sides by the elastic sheet 104. The ejected distances of sand grains with different weights are different, so that the falling sand grains can be dispersed, and then the contact area between the manufactured sand and the wind is increased to improve the air separation effect.

Taking the perspective of the person observing as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
