Description

Technical Field

[0001] This invention relates to the field of calcium carbonate production technology, specifically to an integrated mixing and drying machine for calcium carbonate production. Background Technology

[0002] The limestone roasting method is one of the more common industrial methods for producing calcium carbonate. First, the limestone is pretreated and sintered to obtain calcium oxide. Then, it undergoes a water reaction to produce calcium hydroxide, which reacts with carbon dioxide to form calcium carbonate and water. The resulting calcium carbonate is in a moist state, so it needs to be dried.

[0003] After the workers place the moist calcium carbonate into the mixing and drying machine, the calcium carbonate will form clumps and stick to the wall because it contains a certain amount of moisture. As the drying process continues, the clumps of calcium carbonate will dry unevenly, that is, the inside of the clumps of calcium carbonate will not dry sufficiently, while the outside of the clumps of calcium carbonate will be over-dried.

[0004] Calcium carbonate that sticks to the walls will adhere to the walls and corners of the drying tank, preventing it from being mixed with the stirring components and resulting in uneven drying.

[0005] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes an integrated mixing and drying machine for calcium carbonate production, which solves the above-mentioned technical problems. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes an integrated mixing and drying machine for calcium carbonate production. This invention uses a scraper to scrape up the calcium carbonate inside the cylinder sleeve, and a spreading plate to separate the moist calcium carbonate through the mesh, thereby improving the uniformity of drying the moist calcium carbonate and thus improving the quality of the dried calcium carbonate.

[0007] The technical solution adopted by this invention to solve its technical problem is: a mixing and drying integrated machine for calcium carbonate production, comprising:

[0008] A sleeve; the sleeve is placed horizontally and is open at both ends; one end of the sleeve is hinged and covered with a sleeve cover; the other end of the sleeve is rotatably and sealed to a sleeve base; the sleeve wall is provided with a heating component, which is used to heat the material inside the sleeve to cause moisture loss; the outer wall of the sleeve is provided with a steam channel for water vapor to flow away, so that the water vapor formed in the material after heating can flow away.

[0009] A base; the base is located below the sleeve; the upper end of the base is hinged to one end of the sleeve via a support; the upper end of the base is supported at the other end of the sleeve by a hydraulic cylinder;

[0010] Main shaft; the main shaft is fixedly connected to the center of the cylinder base; the main motor output shaft is fixedly connected to the center of the outer wall of the cylinder base; the outer wall of the main motor and the outer wall of the cylinder are fixedly connected by an L-shaped rod;

[0011] Scraper; the scraper is uniformly fixed to the outer wall of the main shaft; the edge of the scraper contacts the sleeve, the base, and the cover; the scraper is provided with mesh holes;

[0012] A screw; the screw is rotatably connected to the scraper via a support block; the central axis of the screw is parallel to the central axis of the main shaft; one end of the screw extends to the outer wall of the cylinder seat and is fixedly connected to the output shaft of the auxiliary motor; the outer wall of the auxiliary motor is fixedly connected to the cylinder seat;

[0013] The slab; the slab is connected to the screw via a block and threaded transmission; the slab is in inclined contact with the end face of the scraper;

[0014] Controller; The controller is used to control the automatic operation of the mixing and drying integrated machine; During the movement of the spreader, a downward squeezing force is applied to the calcium carbonate on the scraper, so that the calcium carbonate on the scraper moves through the mesh on the scraper under the squeezing of the spreader and moves to the bottom of the scraper, and finally flows into the sleeve near the base; With the help of the mesh and the spreader, the wet calcium carbonate is separated according to the size of the mesh hole.

[0015] Preferably, the edge of the scraper is bent in the direction of scraper rotation; the spreader is elastic; and the calcium carbonate on the scraper moves from a position near the inner wall of the sleeve towards the main shaft.

[0016] Preferably, the block is threadedly connected to the screw; a groove is provided on the lower end face of the block; a slider is slidably connected in the groove; the slider is connected to the bottom of the groove by a spring; two triangular blocks are fixedly connected to one end of the scraper facing the pavement; the triangular blocks are positioned close to the support block; through the cooperation of the triangular blocks and the elastic pavement, the pavement adjusts its tilt direction automatically after moving to the end of the screw.

[0017] Preferably, the scraper is elastic; the rotating inner wall of the sleeve is corrugated; the edge of the scraper abuts against the inner wall of the sleeve and deforms as it rotates; the rotating scraper vibrates as it moves along the corrugated inner wall of the sleeve.

[0018] Preferably, the edge of the slab away from the scraper is fixedly connected to an intercepting rod; adjacent intercepting rods are arranged in contact; during the movement of the scraper along the main shaft and the inner wall of the sleeve, the deformation of the scraper will cause the slab to deform accordingly, and the end of the intercepting rod away from the slab will be squeezed back and forth and staggered after the slab deforms.

[0019] Preferably, a stop bar is provided on the side of the scraper that contacts the spreader; the stop bar is elastic; the stop bar deforms under the pressure of the spreader.

[0020] Preferably, the intercepting rod is tilted in the same direction as the pavement; the intercepting rod is offset from the blocking rod.

[0021] Preferably, the end of the baffle bar near the scraper is rotatably connected to the scraper via a torsion spring; the baffle bar is perpendicular to the end face of the scraper in the initial state; the rotation direction of the baffle bar and the scraper is towards the main shaft; the torque of the torsion spring is less than the elastic force of the baffle bar itself; the blocky or bonded calcium carbonate slows down its movement speed under the obstruction of the baffle bar, and as the spreader continues to move, the slowed blocky or bonded calcium carbonate is more easily pressed into the space between the spreader and the scraper.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention uses a scraper to scrape up the calcium carbonate inside the sleeve, and a spreading plate to separate the moist calcium carbonate through the mesh, thereby improving the uniformity of drying the moist calcium carbonate and thus improving the quality of the dried calcium carbonate.

[0024] 2. In this invention, the calcium carbonate on the scraper moves from a position near the inner wall of the sleeve towards the main shaft, so that the calcium carbonate scraped by the scraper is more evenly distributed on the scraper after the movement, which increases the amount of calcium carbonate squeezed on the scraper in a single movement of the spreader and improves the efficiency of calcium carbonate on the scraper in the segmentation extrusion.

[0025] 3. The present invention, through the cooperation of a triangular block and an elastic plate, allows the plate to adjust its tilt direction automatically after moving to the end of the screw. This enables the plate to compress the calcium carbonate on the scraper as the screw moves back and forth, greatly improving the efficiency of calcium carbonate compression on the scraper, and thus improving the drying efficiency after the calcium carbonate is compressed and divided.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 9 As shown, the present invention is detailed in the following embodiments:

[0039] Example 1: A mixing and drying integrated machine for calcium carbonate production, comprising:

[0040] Sleeve 1; the sleeve 1 is placed horizontally and is open at both ends; one end of the sleeve 1 is hinged and covered with a sleeve cover 11; the other end of the sleeve 1 is rotatably and sealingly connected to a sleeve base 12; the sleeve 1 is provided with a heating component 13 on its sleeve wall, which is used to heat the material inside the sleeve 1 to cause it to lose moisture; the sleeve 1 is provided with a steam channel for water vapor to flow away, so that the water vapor formed in the material after heating can flow away.

[0041] Base 2; the base 2 is located below the sleeve 1; the upper end of the base 2 is hinged to one end of the sleeve 1 via a support 21; the upper end of the base 2 is supported on the other end of the sleeve 1 by a hydraulic cylinder 22;

[0042] Main shaft 3; the main shaft 3 is fixedly connected to the center of the sleeve 12; the output shaft of the main motor 14 is fixedly connected to the center of the outer wall of the sleeve 12; the outer wall of the main motor 14 and the outer wall of the sleeve 1 are fixedly connected by an L-shaped rod 15;

[0043] Scraper 4; the scraper 4 is uniformly fixed to the outer wall of the main shaft 3; the edge of the scraper 4 contacts the sleeve 1, the cylinder seat 12 and the cylinder cover 11; the scraper 4 is provided with mesh holes 41;

[0044] Screw 5; the screw 5 is rotatably connected to the scraper 4 via a support block 51; the central axis of the screw 5 is parallel to the central axis of the main shaft 3; one end of the screw 5 extends to the outer wall of the cylinder seat 12 and is fixedly connected to the output shaft of the auxiliary motor 52; the outer wall of the auxiliary motor 52 is fixedly connected to the cylinder seat 12.

[0045] The slab 6 is connected to the screw 5 via a block 61; the slab 6 is in inclined contact with the end face of the scraper 4.

[0046] Controller; the controller is used to control the automatic operation of the mixing and drying integrated machine;

[0047] During operation, after the worker places the moist calcium carbonate into the mixing and drying machine, the calcium carbonate will clump and stick to the walls because it contains a certain amount of moisture. As the drying process continues, the clumps of calcium carbonate will dry unevenly, meaning that the inside of the clumps will not dry sufficiently while the outside will be over-dried. The calcium carbonate that sticks to the walls and corners of the drying tank will not be able to be mixed with the mixing components, resulting in uneven drying.

[0048] Therefore, before using the integrated mixing and drying machine, the operator first checks that the machine is fault-free and that the inside of the sleeve 1 is clean and free of contamination. Then, the operator opens the sleeve cover 11 and controls the hydraulic cylinder 22 to shorten it, so that the other end of the sleeve 1 is horizontally lower than the first end. After preparing calcium carbonate using the limestone calcination method, the calcium carbonate containing moisture is poured into the sleeve 1 from one end. Alternatively, auxiliary materials can be added to achieve mixing. After the calcium carbonate is poured into the inside of the sleeve 1, the operator closes and locks the sleeve cover 11 at one end of the sleeve 1 and starts the heating assembly 13 to heat the calcium carbonate inside the sleeve 1. The operator then controls the hydraulic cylinder 22 to cyclically extend or shorten the sleeve 1 using the controller. The hydraulic cylinder 22 causes the sleeve 1 to swing back and forth. This back-and-forth swinging of the sleeve 1 causes the calcium carbonate inside the sleeve 1 to move back and forth towards one end or the other. Simultaneously, the controller controls the main motor 14 to rotate. The rotating main motor 14 drives the sleeve base 12 and the main shaft 3 to rotate synchronously. The rotation of the main shaft 3 drives the scraper 4 to rotate inside the sleeve 1. The scraper 4 scrapes up the calcium carbonate inside the sleeve 1. Because the scraper 4 is in contact with the sleeve 1, sleeve cover 11, and sleeve base 12, it achieves scraping without dead angles. The calcium carbonate adhering to the sleeve 1, sleeve cover 11, and sleeve base 12 is scraped away by the scraper 4, achieving mixing and stirring. After the scraper 4 rotates from below the main shaft 3 to a horizontal position, it stops for a period of time. Then, the controller controls the auxiliary motor... When the machine 52 rotates, the auxiliary motor 52 drives the screw 5 to rotate. The rotation of the screw 5 moves the spreading plate 6 from one end of the screw 5 to the other. During the movement, the spreading plate 6 forms an angle with the scraper 4. Thus, during the movement of the spreading plate 6, it exerts a downward squeezing force on the calcium carbonate on the scraper 4, causing the calcium carbonate on the scraper 4 to pass through the mesh 41 on the scraper 4 under the pressure of the spreading plate 6 and move to the bottom of the scraper 4, finally flowing into the sleeve 1 near the base 2. Even if the calcium carbonate on the scraper 4 clumps together, the clumps will be crushed by the pressure of the spreading plate 6. The crushed calcium carbonate will pass through the mesh 41 and be removed. Since moist calcium carbonate is sticky, it passes through the mesh 41. In conjunction with the action of the spreader 6, the moist calcium carbonate is separated according to the size of the mesh 41, so that the calcium carbonate can be heated evenly and dried evenly. The moisture in the calcium carbonate turns into water vapor during drying and finally flows away along the steam channel. In this invention, there are multiple scrapers 4 on the main shaft 3. Multiple scrapers 4 circulate to scrape and separate the calcium carbonate inside the sleeve 1, preventing the moist calcium carbonate from sticking together and affecting the drying effect. After the calcium carbonate inside the sleeve 1 is dried, the controller will stop the rotation of the auxiliary motor 52 and the main motor 14. As the operator opens the sleeve cover 11, the controller controls the main motor 14 to rotate and controls the hydraulic cylinder 22 to extend, so that the dried calcium carbonate inside the sleeve 1 is poured out.

[0049] The present invention uses a scraper 4 to scrape up the calcium carbonate inside the sleeve 1, and a spreading plate 6 to separate the moist calcium carbonate through the mesh 41, thereby improving the uniformity of drying of the moist calcium carbonate and thus improving the quality of the dried calcium carbonate.

[0050] In this embodiment, the edge of the scraper 4 is bent in the direction of rotation of the scraper 4; the spreader 6 is elastic; during operation, as the scraper 4 circulates and scrapes up the calcium carbonate inside the sleeve 1, the calcium carbonate becomes horizontal after rotating around the main shaft 3 with the scraper 4. Then the controller controls the auxiliary motor 52 to drive the screw 5 to rotate, and the spreader 6 spreads the calcium carbonate on the scraper 4. Since the edge of the scraper 4 is bent in the direction of rotation of the scraper 4, the edge of the scraper 4 is at a higher position after it becomes horizontal. This causes the calcium carbonate on the scraper 4 to move from the position close to the inner wall of the sleeve 1 towards the main shaft 3, so that the calcium carbonate scraped up by the scraper 4 is more evenly distributed on the scraper 4 after moving, increasing the amount of calcium carbonate squeezed on the scraper 4 in a single movement of the spreader 6, and improving the efficiency of calcium carbonate on the scraper 4 in the split extrusion.

[0051] In this embodiment, the block 61 is threadedly connected to the screw 5; a groove 62 is provided on the lower end face of the block 61; a slider 63 is slidably connected in the groove 62; the slider 63 is connected to the bottom of the groove 62 by a spring 64; two triangular blocks 65 are fixedly connected to one end of the scraper 4 facing the spreader 6; the triangular blocks 65 are located close to the support block 51; during operation, as the auxiliary motor 52 drives the screw 5 to rotate, the rotating screw 5 drives the block 61 to move, and the block 61 moves During the process, the spreader 6 will move synchronously. As the spreader 6 moves from one end of the screw 5 to the other, it will come into contact with the triangular block 65. The inclined surfaces on the two triangular blocks 65 will approach each other. As the spreader 6 moves, it will move upward under the guidance and compression of the inclined surfaces on the triangular blocks 65. After the spreader 6 moves upward, it will drive the slider 63 to move within the groove 62. After the spreader 6 moves past the triangular block 65 to the other end of the screw 5, the auxiliary motor 52 will drive the screw 5 to reverse. The reversed screw 5 will drive the block 61 from the other end of the screw 5. As the block 61 moves towards one end, it drives the slider 63 and the pavement 6 to move synchronously. The triangular block 65 cannot guide the pavement 6, causing its lower edge to be stuck and limited. As the block 61 continues to move, driven by the screw 5, the upper edge of the pavement 6 moves with it, while its lower edge remains fixed by the triangular block 65. This changes the tilt direction of the elastic pavement 6, allowing it to move from the other end of the screw 5 towards one end as well. The slide 62 can compress the calcium carbonate on the scraper 4 while it is tilted, and the spring 64 in the slide 62 compresses the slide plate 6 to be tilted. In this embodiment, the triangular block 65 cooperates with the elastic slide plate 6, so that the slide plate 6 adjusts its tilt direction automatically after moving to the end of the screw 5. In this way, the slide plate 6 can compress the calcium carbonate on the scraper 4 as it moves back and forth with the screw 5, which greatly improves the efficiency of the calcium carbonate being compressed on the scraper 4, and thus improves the drying efficiency after the calcium carbonate is compressed and divided.

[0052] Example 2 differs from Example 1 in that:

[0053] The scraper 4 is elastic; the inner wall of the sleeve 1 is corrugated; the edge of the scraper 4 abuts against the inner wall of the sleeve 1 and deforms with rotation; during operation, as the scraper 4 rotates with the main shaft 3 to scrape up the calcium carbonate inside the sleeve 1, the edge of the scraper 4 slides relative to the inner wall of the sleeve 1. Since the inner wall of the sleeve 1 is corrugated, the rotating scraper 4 vibrates as it moves against the corrugated inner wall of the sleeve 1. The vibrating scraper 4 removes any unformed calcium carbonate deposits on it. The lumps of calcium carbonate flow quickly along the mesh 41, so that after the scraper 4 moves to a horizontal position with the main shaft 3, most of the lumps and adhesions of calcium carbonate are intercepted and left behind. Compared with the original method of squeezing and dividing the entire calcium carbonate material in the sleeve 1, this embodiment can specifically treat the lumps and adhesions of calcium carbonate, which greatly improves the processing efficiency of calcium carbonate. The spreader 6 is elastic and can change with the deformation of the scraper 4. The shaking scraper 4 will also cause the calcium carbonate on the scraper 4 to spread from the inner wall of the sleeve 1 towards the main shaft 3.

[0054] In this embodiment, the edge of the spreader 6 away from the scraper 4 is fixedly connected to the intercepting rod 7; adjacent intercepting rods 7 are arranged in contact; during operation, the spreader 6 moves back and forth along the screw 5 under the drive of the block 61. During the movement of the spreader 6, the intercepting rod 7 will move synchronously. The intercepting rod 7 will intercept some clumps of calcium carbonate, while excess calcium carbonate without clumps will pass over the intercepting rod 7 and be broken up by the intercepting rod 7 and left along the mesh 41. When the intercepting rod 7 is touched by calcium carbonate, since the intercepting rod 7 is fixedly connected to the spreader 6, the intercepting rod... 7 causes the spreader 6 to shake slightly. After shaking, the spreader 6 squeezes away the calcium carbonate between the spreader 6 and the scraper 4, improving the effect of the spreader 6 in squeezing the calcium carbonate. More importantly, in order to ensure the interception effect of the intercepting rod 7, when the scraper 4 moves with the main shaft 3 and the inner wall of the sleeve 1, the deformation of the scraper 4 will cause the spreader 6 to deform as well. The end of the intercepting rod 7 away from the spreader 6 is squeezed back and forth and staggered after the spreader 6 deforms, so that the calcium carbonate attached to the intercepting rod 7 falls off, avoiding the calcium carbonate from affecting the use effect of the intercepting rod 7.

[0055] Example 3 differs from Example 1 in that:

[0056] A baffle 8 is provided on the side of the scraper 4 that contacts the spreader 6; the baffle 8 is elastic; the baffle 8 deforms under the pressure of the spreader 6.

[0057] In this embodiment, the interceptor 7 is tilted in the same direction as the board 6; the interceptor 7 is offset from the barrier 8.

[0058] In this embodiment, the end of the baffle bar 8 near the scraper 4 is rotatably connected to the scraper 4 via a torsion spring 81; the baffle bar 8 is perpendicular to the end face of the scraper 4 in the initial state; the rotation direction of the baffle bar 8 and the scraper 4 is towards the main shaft 3; the torque of the torsion spring 81 is less than the elastic force of the baffle bar 8 itself.

[0059] During operation, a baffle 8 is provided on the side of the scraper 4 that contacts the spreader 6. This baffle 8 slows down the movement of lumpy or agglomerated calcium carbonate as the spreader 6 spreads and extrudes the calcium carbonate from the scraper 4. As the spreader 6 continues to move, the slowed-down lumpy or agglomerated calcium carbonate is more easily pressed between the spreader 6 and the scraper 4, improving the efficiency and success rate of calcium carbonate extrusion from the mesh 41. The torsion spring 81 allows the baffle 8 to rotate without deformation, ensuring its rotation is perpendicular to the length of the screw 5. This allows the calcium carbonate to overcome the torsion spring 81 and rotate the baffle 8 as the scraper 4 lifts the calcium carbonate from the sleeve 1, preventing the calcium carbonate from being blocked by the baffle 8 and thus preventing it from failing to extrude from the scraper 4. The spread-out situation occurs, and the rotation direction of the baffle 8 also ensures the interception effect on the blocky calcium carbonate along the length of the screw 5. In this embodiment, the interception rod 7 and the tilt direction of the spreader 6 are consistent. On the one hand, the interception rod 7 can still play an interception role after the spreader 6 tilts. On the other hand, the interception rod 7 moves closer to the baffle 8 as the spreader 6 moves. After the baffle 8 moves relative to the adjacent interception rod 7, the interception rod 7 also plays a role in sorting the baffle 8, causing the calcium carbonate on the baffle 8 to detach. In this embodiment, after the spreader 6 bends the baffle 8, the spreader 6 itself will overcome the spring 64 and move upward while passing over the bent baffle 8, without interfering with the movement of the spreader 6. During the reset process, the baffle 8 will also further disperse the blocky calcium carbonate that missed passing the interception rod 7.
