Description

Technical Field

[0001] The invention belongs to the technical field of air separation equipment, and in particular to a stone powder air separation device and method for full dry production. Background Art

[0002] Mechanized 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.). In some engineering construction processes, machine-made sand is used instead of natural river sand, but the machine-made sand contains a certain amount of stone powder, which will affect the construction quality. Therefore, it is necessary to use air separation and dust removal equipment to remove the stone powder in the machine-made sand. The stone powder air separation device in the full dry production is a device that separates materials of different particle sizes in stone powder through air flow. It is mainly used for stone powder processing in the ore, quartz, sand and stone industries, and can effectively remove impurities in the powder and improve the purity of the product. The air separation device controls the air flow speed 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.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 9 As shown, a stone powder air separation device for full dry production according to an embodiment of the present invention comprises: A material barrel 1, wherein one end of the material barrel 1 is a closed structure, and a cover plate 3 is rotatably mounted on the other end, an air inlet pipe 4 is rotatably mounted in the middle of the cover plate 3, and an air outlet pipe 5 is rotatably mounted in the middle of the closed end of the material barrel 1; A suspension assembly, the suspension assembly includes a suspension frame 2 and a support frame 6, the support frame 6 includes a ring 61 symmetrically sleeved on both ends of the material barrel 1, a plurality of rollers 62 are evenly installed on the contact surface between the ring 61 and the material barrel 1, and the support frames 6 on both sides are fixed below the suspension frame 2; A driving assembly 7, wherein the driving assembly 7 comprises a motor 71 fixed to the outside of the material barrel 1, a gear ring 73 is fixed to the outer wall of the material barrel 1, a gear 72 is fixed to the output shaft of the motor 71, and the gear 72 is meshed with the gear ring 73; A paddle plate 9, wherein the paddle plate 9 is axially fixed to the inner wall of the material barrel 1; During operation, the cover plate 3 is opened, and the machine-made sand is loaded into 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 paddle plate 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. The wind is introduced into the material barrel 1 from the air inlet pipe 4 and discharged from the air outlet pipe 5 at the other end. The paddle plate 9 rotates with the material barrel 1, and the machine-made sand at the lowest position is repeatedly lifted to a high place and scattered by the paddle plate 9, so that the machine-made sand can be repeatedly air-selected, and more stone powder in the machine-made sand can be blown out by wind force, thereby improving the air selection effect; in addition, the machine-made sand is repeatedly sprinkled from a high place, and the repeated friction between multiple sand grains helps to shake off the stone powder attached to the surface of the sand grains, thereby further improving the stone powder air selection effect.

[0023] It also includes a material spreading component 10, which includes a material storage box 101. The material storage box 101 is set to a trapezoidal shape. The upper and lower sides of the material storage box 101 are open. A sealing plate 102 is provided on the side of the inner wall of the material storage box 101 away from the material barrel 1. The sealing plate 102 is magnetic and can be adsorbed on the outer side of the opening of the material 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 long rods 107 on both sides. The long rods 107 slide through the side walls of the material barrel 1. The outer side of the material barrel 1 is provided with an outer shell 8, and the outer shell 8 is fixed to the bottom of the suspension frame 2. A boss 1015 is fixed on the inner wall of the top of the outer shell 8; During operation, when the paddle plate 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 paddle plate 9 rotates with the material barrel 1, and the machine-made sand at the lower position is automatically loaded into the storage box 101. The machine-made sand is lifted to the highest position through the paddle plate 9 and the storage box 101. At the same time, the long rod 107 moves synchronously to the highest position, and 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 squeezed by the boss 1015, and then the sealing plate 102 is pushed open by the long rod 107. At this time, the machine-made sand inside the storage box 101 can be sprinkled from the highest position of the material barrel 1, so as to extend the contact time between the machine-made sand and the wind, thereby improving the air selection effect.

[0024] A movable block 103 is provided on the side of the sealing plate 102, and the contour of the movable block 103 is adapted to the opening of the storage box 101 away from the inner wall of the material barrel 1, and the movable block 103 is slidably arranged in the opening, and an active cavity is opened between the sealing plate 102 and the movable block 103, and the end of the long rod 107 slides through the inside of the active cavity, and a fixed block 105 is fixed on the end of the long rod 107, and a spring 106 is installed inside the active cavity, and magnetic blocks 1014 are fixed at intervals on the inner wall of the shell 8; when working, as Figure 8As shown, when the storage box 101 rotates toward the highest position, the long rod 107 first passes through the magnetic block 1014 area. When the long rod 107 is aligned with the magnetic block 1014, the long rod 107 is attracted by the magnetic block 1014, and the long rod 107 pulls the movable block 103 along the opening position toward the inside of the storage box 101 through the fixed block 105. The spring 106 is stretched. At this time, the movable block 103 synchronously pushes the machine-made sand in the box to move upward. When the long rod 107 completely passes through the magnetic block 1014, the movable block 103 is reset by the spring 106. At this time, the machine-made sand in the box moves downward. There are multiple magnetic blocks 1014 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 as to make the sand particles collide and rub against each other before scattering the machine-made sand, which helps to shake off the stone powder attached to the surface of the sand particles, thereby further improving the stone powder air selection effect.

[0025] 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 boss 1015 to push the sealing plate 102 open, and 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 highly elastic and wear-resistant rubber. When the machine-made sand is sprinkled 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 particles so that the sand particles below collide with the sand particles above, which can further shake off the stone powder attached to the surface of the sand particles, so as to improve the air separation effect.

[0026] A sleeve rod 108 is fixed in the middle of the elastic sheet 104. The sleeve rod 108 is slidably sleeved outside the long rod 107. One end of the sleeve rod 108 away from the elastic sheet 104 penetrates and extends to the outside of the material barrel 1, and a third spring 1016 is installed at the end. A cross bar 109 is provided in the middle of the elastic sheet 104. The cross bar 109 is fixed on both sides of the sleeve rod 108. Installation holes 1010 are respectively formed at both ends of the elastic sheet 104. A limiting rod 1011 is arranged inside the installation hole 1010. The limiting rod 1011 is in the shape of "冖", and both ends of the limiting rod 1011 are respectively slidably arranged in sliding cavities formed at the ends of the movable block 103. A second spring 1012 for resetting the limiting rod 1011 is installed inside the sliding cavity. During operation, 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 upward relatively from the middle through the sleeve rod 108 and the cross bar 109. The third spring 1016 limits the movement range of the sleeve rod 108. The two ends of the elastic sheet 104 are pulled to move downward through the second spring 1012, so that the middle part of the elastic sheet 104 bulges upward, and the elastic sheet 104 is in 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 through the elastic sheet 104. Sand grains of different weights are bounced by different distances, so that the falling sand grains can be dispersed, thereby increasing the contact area between the manufactured sand and the wind and improving the air separation effect.

[0027] The installation hole 1010 is a kidney-shaped hole; during operation, when the elastic sheet 104 is pulled up from the middle, the limiting rod 1011 moves along the installation hole 1010, so that when the elastic sheet 104 deforms, the pulling force received is smaller, thereby extending the service life of the elastic sheet 104.

[0028] Two ends of the top of the suspension bracket 2 are respectively fixed with suspension rings. The suspension rings on both sides are respectively suspended below the installation frame through steel cables. A winch for respectively controlling the release and winding of the steel cables on both sides is installed on the installation frame; during operation, when loading, first open the cover plate 3 and release the steel cable, so that the side of the material barrel 1 with the cover plate 3 is tilted upward, and the manufactured sand is loaded into the material barrel 1. Then close the cover plate 3, and then wind the steel cable to keep the material barrel 1 horizontal; after air separation is completed, release the steel cable, so that the side of the material barrel 1 with the cover plate 3 is tilted downward, open the cover plate 3, and pour out the manufactured sand remaining after air separation, that is, one air separation work is completed.

[0029] Two sides of the storage box 101 are respectively provided with telescopic rods 1013. Two sides of the telescopic rods 1013 are respectively fixedly connected with the storage box 101 and the sealing plate 102; during operation, by arranging the telescopic rods 1013, the movement direction of the storage box 101 is limited, so that the storage box 101 can be aligned with the opening position of the storage box 101.

[0030] Embodiment 2: Figure 8 As shown, compared with Example 1, another implementation of the present invention is: the boss 1015 extends from the top of the shell 8 to the side; during operation, when the elastic sheet 104 is pulled up from the middle, the limit rod 1011 moves along the mounting hole 1010, so that there is a gap between the two side edges of the elastic sheet 104 and the surface of the movable block 103, and by extending the length of the boss 1015, when the storage box 101 passes the highest point, the elastic sheet 104 remains in a pulled state, so that the sand particles that accidentally fall under the elastic sheet 104 can be discharged.

[0031] like Fig.10 As shown, a stone powder air separation method for full dry production, which is applicable to the above-mentioned stone powder air separation device for full dry production, comprises the following steps: S1. Open the cover plate 3 and release the steel cable so that the side of the material barrel 1 with the cover plate 3 is tilted upward, put the machine-made sand into the material barrel 1, close the cover plate 3, and then reel in the steel cable to keep the material barrel 1 horizontal; S2, start the motor 71, the motor 71 drives the gear 72 to rotate, and then drives the gear ring 73, the material barrel 1 and the paddle 9 to rotate, and at the same time, the air is introduced into the material barrel 1 from the air inlet pipe 4 and discharged from the air outlet pipe 5 at the other end; S3. When the paddle 9 moves to the lowest position, the sealing plate 102 closes the opening of the material storage box 101 under the influence of gravity, and the paddle 9 rotates with the material barrel 1, automatically loading the machine-made sand at the lower position into the material storage box 101, and the machine-made sand is lifted to the highest position through the paddle 9 and the material storage box 101; S4, when the material storage box 101 rotates toward the highest position, when the long rod 107 is opposite to the magnetic block 1014, the long rod 107 is attracted by the magnetic block 1014, and then the movable block 103 is pulled toward the inside of the material storage box 101. When the long rod 107 completely passes the magnetic block 1014, the movable block 103 is pulled back to its original position through the spring 106, and the movable block 103 reciprocates to stir the machine-made sand inside the material storage box 101; S5, when the material storage box 101 rotates to the highest position, the long rod 107 is squeezed by the boss 1015 to push the sealing plate 102 open, and the machine-made sand is scattered from the material storage box 101 for air separation; 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, and the sleeve rod 108 and the cross bar 109 pull the elastic sheet 104 upward from the middle, so that the elastic sheet 104 is in an inverted V shape to block the top of the movable block 103, and the elastic sheet 104 bounces the spread machine-made sand to both sides to increase the contact area between the machine-made sand and the wind; S7. After the air separation is completed, the steel cable is released so that the side of the material barrel 1 equipped with the cover plate 3 is tilted downward, the cover plate 3 is opened, and the machine-made sand left by the air separation is poured out, thus completing one air separation work.

[0032] Working principle: when loading, first open the cover plate 3, release the steel cable, so that the side of the material barrel 1 with the cover plate 3 is tilted upward, load the machine-made sand into the material barrel 1, close the cover plate 3, and then reel in the steel cable to keep the material barrel 1 horizontal; start the motor 71, the motor 71 drives the gear 72 to rotate, and then drives the gear ring 73, the material barrel 1 and the paddle 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, and the air is introduced from the air inlet pipe 4 into the material barrel 1 and discharged from the air outlet pipe 5 at the other end, the paddle 9 rotates with the material barrel 1, and the machine-made sand at the lowest position is repeatedly lifted to a high place and scattered by the paddle 9, so that the machine-made sand can be repeatedly air-selected, and more stone powder in the machine-made sand can be blown out by wind, thereby improving the air selection effect; When the paddle plate 9 moves to the lowest position, the sealing plate 102 closes the opening of the material storage box 101 under the influence of gravity, and the sealing plate 102 is adsorbed at the opening position. The paddle plate 9 rotates with the material barrel 1, and the machine-made sand at the lower position is automatically loaded into the material storage box 101. The machine-made sand is lifted to the highest position through the paddle plate 9 and the material storage box 101. When the material storage box 101 rotates toward the highest position, the long rod 107 first passes through the area of ​​the magnetic block 1014. When the long rod 107 is aligned with the magnetic block 1014, the long rod 107 is attracted by the magnetic block 1014, and the long rod 107 pulls the movable block 103 along the opening position to the upper side through the fixed block 105. As the storage box 101 moves inside, the spring 106 is stretched, and the movable block 103 synchronously pushes the machine-made sand in the box to move upward. When the long rod 107 completely passes through the magnetic block 1014, the movable block 103 is reset by the spring 106, and the machine-made sand in the box moves downward. There are multiple magnetic blocks 1014 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 as to make the sand particles collide and rub against each other before scattering the machine-made sand, which helps to shake off the stone powder attached to the surface of the sand particles, and further improve the stone powder air separation effect; When the material storage box 101 is moved to the highest position, the long rod 107 moves to the highest position synchronously at the same time, and 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 squeezed by the boss 1015, and then the sealing plate 102 is pushed open by the long rod 107. At this time, the machine-made sand inside the material storage box 101 can be sprinkled from the highest position of the material barrel 1, so as to prolong the contact time between the machine-made sand and the wind, thereby improving the wind selection effect; 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, and the elastic sheet 104 is pulled upward from the middle by the sleeve rod 108 and the cross bar 109, and the two ends of the elastic sheet 104 are pulled downward by the spring 2 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.
