[0002] Heavy calcium carbonate, referred to as heavy calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. At present, wet grinding is to mix qualified block materials with liquid solvents and then grind and crush them to obtain heavy calcium suspension after grinding. Then, the heavy calcium suspension is centrifuged to remove water to obtain wet heavy calcium powder. In order to ensure the quality of the heavy calcium powder when it is used, the wet heavy calcium powder needs to be dried. There are many existing methods for drying heavy calcium powder. Among them, the drum drying method is to introduce hot air into the inside of the drum when drying the heavy calcium powder, and the drum is constantly turning the heavy calcium powder therein, so that the heavy calcium powder is in contact with the hot air, so that the hot air is used to take away the moisture in the heavy calcium powder. However, since some heavy calcium powder forms aggregates under the action of water, the heavy calcium powder inside these aggregates cannot fully contact with the hot air, and the drum cannot effectively treat the aggregates, resulting in the heavy calcium powder cannot be fully dried within the specified time, so that the heavy calcium powder is not completely dried, affecting the subsequent processing and normal use of the heavy calcium powder.

[0044] Workflow: During the production of heavy calcium powder, the staff feeds the ground heavy calcium powder into the feed shell 2, and the heavy calcium powder in the feed shell 2 gradually moves to the left and enters the drying shell 4. The staff starts the air pump on the discharge shell 3, and the air pump on the discharge shell 3 delivers hot air to the drying shell 6 through the air inlet pipe 5. The hot air enters the drying shell 4 through the through hole on the drying shell 6 to dry the heavy calcium powder. After that, the hot air is discharged from the air outlet of the discharge shell 3 to the air pump thereon for reuse. At the same time, the staff starts the power motor and the transmission motor 16 of the feed shell 2, and the output shaft of the transmission motor 16 drives the two crushing racks 12 to rotate counterclockwise ( Figure 5The output shaft of the power motor of the feed shell 2 drives the power tube 7 to rotate through the gear set, the drying shell 6 drives the drying shell 4 to rotate through the rotating shell 8, the drying shell 4 drives the collecting mechanism to rotate, the collecting mechanism drives part of the heavy calcium powder to move, and sprinkles the heavy calcium powder on the top of the drying shell 6, so that the heavy calcium powder is fully in contact with the hot air, and at the same time the collecting mechanism screens the heavy calcium powder, and sends the aggregated blocks in the heavy calcium powder to the upper side of the guide frame 14, and the aggregated blocks enter the crushing frame 12 and the arc frame 1 along the guide frame 14. 3, the pull rope on the crusher frame 12 cooperates with the pull rope on the arc frame 13 during its rotation process to cut and crush the surface of the aggregate block, so that the volume of the aggregate block is gradually reduced and gradually dispersed, increasing its contact area with the hot air, ensuring the hot air drying effect on the heavy calcium powder in the aggregate block, until the volume of the aggregate block is smaller than the gap between two adjacent pull ropes, the aggregate block is discharged from between the crusher frame 12 and the arc frame 13, and as the heavy calcium powder gradually moves to the left, the dried heavy calcium powder is discharged from the discharge port of the discharge shell 3.

[0045] Furthermore, Figure 4 and Figure 8-Figure 10 As shown, the material collecting mechanism includes: a connecting plate 17, which is fixed in the drying shell 4, and the connecting plate 17 is hinged with a material discharge plate 18, and the material discharge plate 18 is provided with a plurality of elliptical holes; a material receiving plate 20, which is hinged to the material discharge plate 18; a rotating component, which is arranged on the connecting plate 17, and the rotating component is used to drive the material receiving plate 20 to rotate.

[0046] The above scheme is used to move the heavy calcium powder to the top of the drying shell 6. In this embodiment and subsequent embodiments, the slide groove and the hinge are provided with a shield to prevent the heavy calcium powder from entering the above area and hindering the normal operation of the device. The connecting plate 17 is used to drive part of the heavy calcium powder at the bottom of the drying shell 4 to move upward, and sprinkle the heavy calcium powder on the upper side of the drying shell 6. The heavy calcium powder on the connecting plate 17 falls through the elliptical hole in the unloading plate 18; the receiving plate 20 and the connecting plate 17 jointly drive the heavy calcium powder to move upward; the rotating assembly is used to drive the receiving plate 20 to rotate, and at the same time screen the aggregated blocks in the heavy calcium powder between the connecting plate 17 and the receiving plate 20.

[0047] Furthermore, Figure 4 and Figure 8-Figure 10 As shown, the rotating assembly includes: a counterweight plate 21, which is slidably connected to the connecting plate 17; a sliding frame 22, which is slidably connected to the connecting plate 17, the counterweight plate 21 is provided with a wire ring, the wire ring of the counterweight plate 21 passes through the sliding frame 22 and is fixed thereto, and the wire ring of the counterweight plate 21 passes through the connecting plate 17; there are multiple push rods 2201, which are all ball-connected to the sliding frame 22, the push rods 2201 are ball-connected to the receiving plate 20, and the multiple push rods 2201 are axially equidistantly distributed.

[0048] In the above scheme, the weight plate 21 and the sliding frame 22 are respectively located on the left and right sides of the connecting plate 17, such as Figure 8 As shown, the wire ring on the counterweight plate 21 is used to drive the sliding frame 22 to move in the opposite direction when it moves, and the pushing rod 2201 is used to intercept the movement of the aggregate block, and in the process of separating the aggregate block from the heavy calcium powder, it drives the receiving plate 20 to rotate so that the receiving plate 20 prevents the aggregate block from falling; the dropping mechanism is used to drive the counterweight plate 21 to move, so that the receiving plate 20 is reset and no longer prevents the aggregate block from falling.

[0049] Furthermore, Figure 2 , Figure 3 , Fig.11 and Fig.12 As shown, it also includes: a material dropping mechanism, which is arranged on the rotating shell 8 and is used to drive the counterweight plate 21 to move; the material dropping mechanism includes: a support ring 23, which is fixed to the drying shell 6, and the support ring 23 is rotatably connected to the drying shell 4; a U-shaped plate 24, which is fixed to the support ring 23, and the U-shaped plate 24 is used to push the counterweight plate 21 close to the side of the support ring 23 to move, and all the counterweight plates 21 located on the same busbar of the drying shell 4 are fixedly connected with a fixed plate 2101.

[0050] In the above scheme, the receiving plate 20 is used to drive the material receiving plate 20 to rotate in the opposite direction, so that the aggregated block between the connecting plate 17 and the receiving plate 20 falls onto the guide frame 14. There are two support rings 23, which are respectively located on the left and right sides of the drying shell 6, and are used to support the drying shell 6 during the drying process of the heavy calcium powder to reduce its deformation. The length of the counterweight plate 21 close to the support ring 23 is greater than the length of the inner counterweight plate 21, and the edge of the counterweight plate 21 close to the support ring 23 is located on the outer side of the connecting plate 17, so that the U-shaped plate 24 can push the counterweight plate 21 to move; an arc surface is provided on the U-shaped plate 24, and the distance between the arc surface and the inner wall of the drying shell 4 decreases in the clockwise direction ( Fig.11 (Viewed from left to right), when the connecting plate 17 drives the counterweight plate 21 to rotate, the U-shaped plate 24 squeezes the adjacent counterweight plate 21, causing the counterweight plate 21 and the connecting plate 17 to move relative to each other. The fixed plate 2101 is used to drive all the counterweight plates 21 on the same busbar of the drying shell 4 to move synchronously.

[0051] Workflow: The moving direction of the parts in this paragraph is shown in reference 8. In the process of the above-mentioned rotation of the drying shell 4, the connection plate 17 is located at the lower side of the drying shell 4. The drying shell 4 drives the connection plate 17, the connection plate 17 drives the unloading plate 18, the counterweight plate 21 and the sliding frame 22 to rotate, the unloading plate 18 drives the receiving plate 20 to rotate, and the sliding frame 22 drives the push rod 2201 to rotate. When the connection plate 17 rotates 90°, as it continues to rotate, the counterweight plate 21 moves upward relative to the connection plate 17 under the influence of gravity and passes The steel wire rope drives the sliding frame 22 to move in the opposite direction. At this time, part of the heavy calcium powder on the connecting plate 17 passes through the elliptical hole of the unloading plate 18 under the action of gravity, and falls to the top of the drying shell 6 to contact with the hot air. The sliding frame 22 moves and drives the receiving plate 20 to rotate through the pushing rod 2201, so that the angle between the receiving plate 20 and the connecting plate 17 is reduced. The receiving plate 20 hinders the movement of the aggregated blocks and prevents the aggregated blocks on the connecting plate 17 from falling. In this process, the pushing rod 2201 moves and intercepts the aggregated blocks in the heavy calcium powder, thereby The aggregated blocks in the calcium powder are screened until the connecting plate 17 rotates 180°, the counterweight plate 21 stops moving, and the receiving plate 20 stops moving. During this process, the heavy calcium powder falls onto the receiving plate 20 through the gap between the two adjacent push rods 2201, and then falls from the elliptical hole of the unloading plate 18 to the top of the drying shell 6 under the action of gravity. The aggregated blocks in the heavy calcium powder are separated, and then the connecting plate 17 continues to rotate. When the counterweight plate 21 near the support ring 23 contacts the U-shaped plate 24, the counterweight plate 21 is on the U-shaped plate 2 4 moves downward relative to the connecting plate 17, so that the receiving plate 20 rotates in the opposite direction to increase the angle between it and the connecting plate 17, and the aggregated blocks on the connecting plate 17 fall onto the guide frame 14. When the counterweight plate 21 is separated from the U-shaped plate 24, the angle between the receiving plate 20 and the connecting plate 17 continues to increase until the connecting plate 17 moves to the lower side of the drying shell 4 again, and the receiving plate 20 is reset, and the angle between it and the connecting plate 17 reaches the maximum. In the above process, the angle between the connecting plate 17 and the receiving plate 20 is referenced to Fig.10 shown.

[0052] Furthermore, Fig.11 and Fig.12 As shown, it also includes: a buffer assembly, which is arranged on the support ring 23 and is used to reduce the impact force of the material on the guide frame 14; the buffer assembly includes: a buffer frame 25, which is fixed to the support ring 23; a connecting rod 26, which is fixed to the guide frame 14, a first spring is arranged between the buffer frame 25 and the connecting rod 26, and the arc frame 13 is rotatably connected to the guide frame 14.

[0053] Furthermore, Fig.12As shown, it also includes: an extrusion plate 27, which is slidably connected to the connecting rod 26, a tension spring is arranged between the extrusion plate 27 and the connecting rod 26, and two inclined surfaces distributed up and down are arranged in the buffer frame 25, and the two inclined surfaces on the buffer frame 25 are used to push the extrusion plate 27 to move.

[0054] In the above scheme, the impact force of the aggregation block on the guide frame 14 is reduced, thereby reducing the probability of the aggregation block being stuck between the pull ropes in the guide frame 14. The guide frame 14 is fixedly connected with a connecting rod 26, and a rectangular groove is provided in the buffer frame 25. The rectangular groove is used to limit the moving distance of the buffer frame 25. The first spring in the buffer frame 25 supports the guide frame 14 through the connecting rod 26 and reduces the rotation angle of the guide frame 14. The upper side of the extrusion plate 27 is provided with an inclined surface, which is used to change the direction of the force exerted by the counterweight plate 21 on the extrusion plate 27, and the length of the projection of the inclined surface on the horizontal plane is less than the relative movable distance between the extrusion plate 27 and the connecting rod 26, so that the upper side surface of the extrusion plate 27 can be moved to the right side of the connecting rod 26, so that the extrusion plate 27 can be squeezed during the rotation of the counterweight plate 21 on the right side (such as Fig.12 As shown in the figure, two inclined surfaces distributed up and down are arranged in the buffer frame 25, and the distance between the left sides of the two inclined surfaces is greater than the distance between the right sides thereof, and both inclined surfaces are used to push the extrusion plate 27 to move to the left, and the elastic coefficient of the tension spring on the extrusion plate 27 is smaller than the elastic coefficient of the first spring on the connecting rod 26, so that the right side of the extrusion plate 27 can enter the connecting rod 26.

[0055] Working process: During the falling process of the aggregation block on the above-mentioned connecting plate 17, when the aggregation block contacts the pull rope in the guide frame 14, the aggregation block rotates by squeezing the pull rope of the guide frame 14, and the guide frame 14 drives the connecting rod 26 to rotate synchronously. The connecting rod 26 drives the extrusion plate 27 to rotate and compresses the first spring thereon. The first spring buffers the impact force between the aggregation block and the guide frame 14, thereby reducing the impact force of the aggregation block on the guide frame 14, thereby reducing the probability of the aggregation block being stuck between the pull ropes of the guide frame 14. Then, the falling aggregation block moves along the pull rope in the guide frame 14 and enters between the crushing frame 12 and the arc frame 13 and is then crushed. When the total amount of the aggregation blocks on the guide frame 14 is reduced, the first spring in the buffer frame 25 pushes the connecting rod 26 to cause the guide frame 14 to rotate in the opposite direction and reset.

[0056] As the aggregation block gradually falls onto the guide frame 14, when the aggregation block is stuck between the pull ropes on the guide frame 14, the total gravity of the guide frame 14 increases, the first spring on the connecting rod 26 is compressed and no longer resets, the connecting rod 26 moves downward relative to the buffer frame 25, the extrusion force of the inner inclined surface of the buffer frame 25 on the extrusion plate 27 is reduced, and the extrusion plate 27 moves to the right under the pull of the adjacent tension springs. As the total amount of the aggregation block stuck between the pull ropes on the guide frame 14 increases, the rotation angle of the guide frame 14 gradually increases, and the distance that the extrusion plate 27 protrudes out of the right side of the connecting rod 26 increases. Until the upper side surface of the extrusion plate 27 completely protrudes out of the right side of the connecting rod 26, the upper side surface of the extrusion plate 27 moves to the rotation path of the counterweight plate 21. As the drying shell 4 drives the counterweight plate 21 to rotate through the connecting plate 17, when the counterweight plate After 21 contacts with the extrusion plate 27, the counterweight plate 21 pushes the extrusion plate 27 to move downward, so that the extrusion plate 27 drives the guide frame 14 to rotate through the connecting rod 26, until the extrusion plate 27 contacts the inclined surface on the lower side of the buffer frame 25, the extrusion plate 27 moves to the left and stretches the tension spring thereon until the extrusion plate 27 is separated from the counterweight plate 21, and the first spring in the buffer frame 25 pushes the connecting rod 26 to move upward and reset quickly, so that the guide frame 14 drives the aggregation block thereon to rotate until the upper side surface of the connecting rod 26 contacts the buffer frame 25 and stops moving, and the extrusion plate 27 is reset under the extrusion of the adjacent inclined surface in the buffer frame 25 and stretches the adjacent tension spring. At this time, the aggregation block continues to move under the action of its own inertia and separates from the guide frame 14, thereby completing the cleaning of the guide frame 14 and reducing the accumulation of aggregation blocks on the guide frame 14.

[0057] Furthermore, Fig.13 and Fig.14 As shown, it also includes: a lifting component, which is arranged on the power tube 7 and is used to drive the connecting frame 11 to move. The lifting component includes: a first extrusion ring 30, which is fixed to the power tube 7, the first extrusion ring 30 is rotatably connected to the air intake pipe 5, and the power tube 7 is rotatably connected to the rotating shell 8; a second extrusion ring 31, which is slidably connected to the rotating shell 8, a second spring is arranged between the second extrusion ring 31 and the rotating shell 8, and the second extrusion ring 31 is in contact with the first extrusion ring 30; a sealing ring 32, which is rotatably connected to the liquid storage shell 9, the sealing ring 32 is rotatably connected to the air intake pipe 5, the liquid storage shell 9 is connected to the rotating shell 8 through a straight tube, and the straight tube on the liquid storage shell 9 is fixed to the sealing ring 32, and the liquid storage shell 9 is connected to the telescopic rod 10 through an infusion tube.

[0058] The above scheme is used to detect the amount of heavy calcium powder in the drying shell 4 and adjust the position of the arc frame 13 according to the amount of heavy calcium powder. The first extrusion ring 30 and the second extrusion ring 31 have the same shape. Initially, the first extrusion ring 30 drives the second extrusion ring 31 to rotate through friction. The first extrusion ring 30 and the second extrusion ring 31 are provided with inclined surfaces on the opposite sides. The first extrusion ring 30 drives the rotating shell 8 to rotate through the second extrusion ring 31 and the second spring in the rotating shell 8. The second spring of the rotating shell 8 is in a compressed state. When the rotating shell 8 rotates, the straight pipe thereon drives the sealing ring 32 to rotate synchronously, thereby ensuring the connection between the liquid storage shell 9 and the rotating shell 8. The liquid storage shell 9 and the rotating shell 8 are both filled with hydraulic oil. The liquid storage shell 9 is connected to the lower part of the telescopic rod 10, so that after the hydraulic oil in the liquid storage shell 9 enters the telescopic rod 10, the telescopic end of the telescopic rod 10 drives the connecting frame 11 to move upward.

[0059] Working process: In the above-mentioned process of drying the heavy calcium powder, the power tube 7 drives the first extrusion ring 30 to rotate, the first extrusion ring 30 squeezes the second extrusion ring 31 to make it rotate synchronously, the second extrusion ring 31 drives the rotating shell 8 to rotate, and the rotating shell 8 drives the sealing ring 32 to rotate synchronously through the straight tube while driving the drying shell 4 to rotate. When the total amount of heavy calcium powder in the drying shell 4 increases, the resistance to the rotation of the drying shell 4 increases, and the second extrusion ring 31 drives the resistance to the rotation of the drying shell 4 to increase through the rotating shell 8. The first extrusion ring 30 squeezes the second extrusion ring 31 and moves relative to it, so that the second extrusion ring 31 is The extrusion ring 31 moves to the left to send the hydraulic oil in the rotating shell 8 into the liquid storage shell 9. At the same time, the second extrusion ring 31 compresses the adjacent second spring, and then the hydraulic oil enters the telescopic rod 10, so that the telescopic end of the telescopic rod 10 is retracted and drives the connecting frame 11 and the parts thereon to move upward, thereby moving the arc frame 13 upward, increasing the distance between it and the accumulated heavy calcium powder at the bottom of the drying shell 4, thereby reducing the accumulation of heavy calcium powder between the pull ropes on the arc frame 13, so that the arc frame 13 and the crushing frame 12 can normally crush the aggregated blocks, ensuring the efficiency of the arc frame 13 and the crushing frame 12 in crushing the aggregated blocks.
