Abstract

This utility model relates to the field of calcium carbonate production technology and discloses a blade assembly for a nano-calcium carbonate stirring device, including a drying cylinder. The upper end of the drying cylinder is covered with a cylinder cover, and a motor is mounted on the upper end of the cylinder cover. An adjustment component is provided at the output end of the motor. The motor rotation drives a turntable to rotate via a first gear. When the inclined surface at the lower end of the turntable gradually rotates towards the upper end of the mounting frame, a lifting rod drives the rotating shaft to move downwards, compressing the spring of the lifting disc. When the inclined surface at the lower end of the turntable gradually moves away from the mounting frame, the rotating shaft moves upwards under the reverse force of the spring. Thus, during the rotation of the turntable, the lifting rod drives the rotating shaft and the stirring blade to move up and down periodically. This allows the stirring blade to periodically stir different layers of calcium carbonate, ensuring that all layers are stirred evenly and heated uniformly, thereby accelerating the drying rate of the calcium carbonate.

Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate production technology, and in particular to a blade assembly for a nano-calcium carbonate stirring device. Background Technology

[0002] Nano-activated calcium carbonate is a form of calcium carbonate, appearing as a white or pale yellow hexagonal crystalline powder. It is odorless, insoluble in water and ethanol, soluble in acids, and releases carbon dioxide. Its chemical formula is CaCO3. Nano-activated calcium carbonate has a particle size ranging from 1 to 100 nm. Nanomaterials exhibit small size effects, surface effects, and macroscopic quantum tunneling effects, thus displaying many unique properties. "Active" indicates that after treatment with surfactants, it possesses unique and excellent activity in certain properties. Nano-activated calcium carbonate indicates that the particle size of this calcium carbonate material is within the nanometer range. After treatment with surfactants, it possesses many special properties compared to ordinary calcium carbonate. Therefore, nano-activated calcium carbonate is a functional inorganic filler. It not only increases product volume and reduces product cost but also possesses excellent reinforcing properties. Drying is an essential process step in the processing and production of nano-activated calcium carbonate.

[0003] A utility model patent with authorization announcement number CN220793666U discloses a drying mechanism for calcium carbonate production, including a frame and a drying cylinder. The drying cylinder contains a turning mechanism for agitating the calcium carbonate within it. The turning mechanism includes staggered crushing rollers and stirring blades. A vibration assembly is located at the bottom of the drying cylinder, below the turning mechanism. The vibration assembly includes a vibrating plate, which loosens the calcium carbonate accumulated on the plate, allowing the turning mechanism to effectively agitate the calcium carbonate. A heating cylinder, rotatably mounted on the frame and fixedly fitted onto the outside of the drying cylinder, provides heat to the drying cylinder. This design offers good drying effect, high drying efficiency, and is economical and practical.

[0004] The aforementioned device uses a rotating shaft to drive a stirring blade to stir and dry calcium carbonate in the drying cylinder. However, the stirring blade can only agitate the calcium carbonate at the bottom of the drying cylinder. The calcium carbonate in the upper layer of the drying cylinder is agitated to a smaller extent. Furthermore, water vapor is emitted from bottom to top, which can easily cause water vapor to be blocked by the upper layer of calcium carbonate and prevent it from evaporating quickly, thus reducing the drying speed.

[0005] Given that the above-mentioned device uses a rotating shaft to drive the stirring blades to stir and dry calcium carbonate in the drying cylinder, but the stirring blades can only agitate the calcium carbonate at the bottom of the drying cylinder, and the calcium carbonate in the upper layer of the drying cylinder is agitated to a smaller extent, and water vapor is emitted from bottom to top, which easily leads to water vapor being blocked by the upper layer of calcium carbonate and unable to be emitted quickly, thus reducing the drying speed, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a blade assembly for a nano-calcium carbonate stirring device, comprising a drying cylinder, a cylinder cover at the upper end of the drying cylinder, a motor at the upper end of the cylinder cover, an adjustment assembly at the output end of the motor, the adjustment assembly including a first gear at the output end of the motor, a rotating rod at the lower end of the first gear, the rotating rod passing through the cylinder cover and connected to a turntable, multiple sets of second gears on the outer wall of the first gear, a rotating cylinder at the lower end of the second gear, a lifting rod inserted in the middle of the rotating cylinder, a lifting plate at the upper end of the lifting rod, a spring sleeved on the outer wall of the lifting rod, and an installation assembly at the lower end of the lifting rod, the installation assembly including an installation frame at the lower end of the lifting rod, a rotating shaft at the lower end of the installation frame, and multiple sets of stirring blades on the outer wall of the rotating shaft.

[0007] As a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, a heating cylinder is sleeved on the lower outer wall of the drying cylinder, and an air outlet is opened at the upper end of the cylinder cover.

[0008] As a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, the outer wall of the drying cylinder is fixedly provided with two sets of symmetrical bolts, the upper end of the outer wall of the bolts is movably fitted with a sleeve plate, the sleeve plate is fixedly connected to the cylinder cover, and the outer wall of the upper end of the bolts is threaded with a nut.

[0009] As a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, multiple sets of the rotating drums are rotatably inserted into the upper end of the drum cover, the second gear and the first gear mesh with each other, and the lower end of the turntable has an inclined surface that cooperates with the mounting frame.

[0010] In a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, the lifting rod is movably inserted into the middle of the rotating drum, the lifting plate is movably inserted into the inner wall of the rotating drum, a slider is fixedly provided on the outer wall of the lifting plate, and a groove that cooperates with the slider is opened on the inner wall of the rotating drum.

[0011] As a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, the mounting assembly further includes a mounting port at the lower end of the mounting frame, the upper end of the rotating shaft is movably inserted into the mounting port, a bidirectional lead screw is rotatably inserted into the inner cavity of the mounting frame, a worm gear is fixedly sleeved at the middle end of the bidirectional lead screw, a worm is provided at the lower end of the worm gear, the worm and the worm gear mesh with each other, the worm is rotatably inserted into the outer wall of the mounting frame, two sets of symmetrical ball screw sleeves are movably sleeved on the outer wall of the bidirectional lead screw, an insertion rod is provided at the lower end of the ball screw sleeve, and an insertion hole is opened on the upper outer wall of the rotating shaft to cooperate with the insertion rod, the insertion rod is movably inserted into the insertion hole.

[0012] As a preferred embodiment of the impeller assembly for the nano-calcium carbonate stirring device of this utility model, the outer wall of the rotating shaft is fixedly provided with two sets of symmetrical positioning rods, the lower end of the mounting frame is provided with positioning holes that cooperate with the positioning rods, and the positioning rods are movably inserted into the positioning holes.

[0013] As a preferred embodiment of the blade assembly for the nano-calcium carbonate stirring device of this utility model, the outer wall of the stirring blade has multiple sets of through holes.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. In this utility model, the motor rotates and drives the turntable to rotate via the first gear. When the inclined surface at the lower end of the turntable gradually rotates towards the upper end of the mounting frame, the lifting rod drives the rotating shaft to move downward and compresses the spring of the lifting plate. When the inclined surface at the lower end of the turntable gradually moves away from the mounting frame, the rotating shaft moves upward under the reverse elastic force of the spring. Thus, during the rotation of the turntable, the lifting rod drives the rotating shaft and the stirring blade to move up and down periodically. This allows the stirring blade to periodically stir different layers of calcium carbonate, ensuring that all layers of calcium carbonate are stirred, resulting in uniform heating of each layer and accelerating the drying rate of calcium carbonate.

[0016] 2. In this utility model, after drying, the nut can be unscrewed from the top of the bolt, and then the sleeves at both ends of the cylinder cover can be slid upwards along the bolt to remove the cylinder cover from the top of the drying cylinder. This makes it easy to pour out the dried calcium carbonate inside the drying cylinder for storage, and the rotating shaft and stirring blades can be removed from the drying cylinder. Then, the worm gear is rotated to drive the worm wheel to rotate, and the worm wheel drives the bidirectional screw to rotate. The two sets of ball screw sleeves move away from each other, and the insertion rod is pulled out from the insertion hole on the outer wall of the upper end of the rotating shaft. Then, the rotating shaft is slid downwards along the installation port to remove the rotating shaft from the installation port. This completes the disassembly between the mounting frame and the rotating shaft, making it easy to clean and maintain the rotating shaft and stirring blades separately. This avoids the problem of excessive calcium carbonate adhering to the upper end of the rotating shaft and stirring blades after long-term use, which would affect the subsequent stirring effect.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a blade assembly for a nano-calcium carbonate stirring device, including a drying cylinder 1, a cylinder cover 2 covering the upper end of the drying cylinder 1, a motor 3 on the upper end of the cylinder cover 2, an adjustment assembly 5 at the output end of the motor 3, the adjustment assembly 5 including a first gear 51 at the output end of the motor 3, a rotating rod 52 at the lower end of the first gear 51, the rotating rod 52 passing through the cylinder cover 2 and connected to a turntable 53, multiple sets of second gears 54 on the outer wall of the first gear 51, a rotating cylinder 55 at the lower end of the second gear 54, a lifting rod 56 inserted in the middle of the rotating cylinder 55, a lifting plate 57 at the upper end of the lifting rod 56, a spring 58 sleeved on the outer wall of the lifting rod 56, and an installation assembly 7 at the lower end of the lifting rod 56, the installation assembly 7 including an installation frame 71 at the lower end of the lifting rod 56, a rotating shaft 8 at the lower end of the installation frame 71, and multiple sets of stirring blades 9 on the outer wall of the rotating shaft 8.

[0026] A heating cylinder 4 is fitted on the lower outer wall of the drying cylinder 1, and an air outlet 6 is opened on the upper end of the cylinder cover 2.

[0027] Multiple sets of rotating drums 55 are rotatably inserted into the upper end of the drum cover 2. The second gear 54 and the first gear 51 mesh with each other. The lower end of the turntable 53 has an inclined surface that cooperates with the mounting frame 71.

[0028] The lifting rod 56 is movably inserted into the middle of the rotating drum 55, and the lifting plate 57 is movably inserted into the inner wall of the rotating drum 55. The outer wall of the lifting plate 57 is fixedly provided with a slider 59, and the inner wall of the rotating drum 55 is provided with a groove that cooperates with the slider 59. The groove not only allows the lifting plate 57 to move up and down along the groove via the slider 59, but also allows the rotating drum 55 to rotate via the slider 59 when the second gear 54 drives the rotating drum 55 to rotate. The rotation of the lifting plate 57 can drive the lifting rod 56 to rotate.

[0029] Multiple sets of through holes are provided on the outer wall of the stirring blade 9. The through holes can reduce the resistance during the rotation of the stirring blade 9 and accelerate the rotation speed of the shaft 8 and the stirring blade 9.

[0030] When the calcium carbonate in the drying cylinder 1 needs to be dried, the heating cylinder 4 can be started to heat the inside of the drying cylinder 1. At the same time, the motor 3 is started to drive the first gear 51 to rotate. The first gear 51 drives multiple sets of second gears 54 to rotate, which in turn drives the rotating cylinder 55 to rotate. The rotating cylinder 55 drives the lifting rod 56 to rotate, which in turn drives the mounting frame 71 and the rotating shaft 8 to rotate. The rotating shaft 8 drives the stirring blade 9 to rotate, stirring the calcium carbonate in the drying cylinder 1 and accelerating the evaporation of moisture from the calcium carbonate. The evaporated moisture is discharged from the drying cylinder 1 through the air outlet 6. During the rotation of the first gear 51, the first gear 51 drives the rotating rod 52 and the turntable 53 to rotate. The lower end of the turntable 53 is provided with an inclined surface that cooperates with the mounting frame 71. As the inclined surface at the lower end of the turntable 53 gradually moves towards the mounting frame 71... When the upper end of the mounting frame 71 rotates, the turntable 53 drives the mounting frame 71 to gradually move downwards. The mounting frame 71 drives the lifting rod 56 to slide downwards along the rotating cylinder 55. The lifting rod 56 drives the rotating shaft 8 to move downwards and causes the lifting plate 57 to compress the spring 58. When the inclined surface at the lower end of the turntable 53 gradually moves away from the mounting frame 71, under the reverse elastic force of the spring 58, the lifting rod 56 moves upwards, and the rotating shaft 8 moves upwards accordingly. Thus, during the rotation of the turntable 53, the lifting rod 56 drives the rotating shaft 8 to move up and down periodically. The rotating shaft 8 drives the stirring blades 9 set on the outer wall to move up and down periodically. Thus, the stirring blades 9 can periodically stir the calcium carbonate at different layers, so that the calcium carbonate at each layer can be stirred, making the calcium carbonate at each layer heat evenly and accelerating the drying rate of calcium carbonate.

[0031] Example 2

[0032] Reference Figure 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: two sets of symmetrical bolts 10 are fixedly provided on the outer wall of the drying cylinder 1, and a sleeve plate 11 is movably sleeved on the upper end of the outer wall of the bolt 10. The sleeve plate 11 and the cylinder cover 2 are fixedly connected, and a nut 12 is threaded on the outer wall of the upper end of the bolt 10 on the sleeve plate 11.

[0033] The mounting assembly 7 also includes a mounting port 78 at the lower end of the mounting frame 71. The upper end of the rotating shaft 8 is movably inserted into the mounting port 78. A bidirectional lead screw 72 is rotatably inserted into the inner cavity of the mounting frame 71. A worm gear 73 is fixedly sleeved at the middle end of the bidirectional lead screw 72. A worm 76 is provided at the lower end of the worm gear 73. The worm 76 and the worm gear 73 mesh with each other. The worm 76 is rotatably inserted into the outer wall of the mounting frame 71. Two sets of symmetrical ball screw sleeves 74 are movably sleeved on the outer wall of the bidirectional lead screw 72. An insertion rod 75 is provided at the lower end of the ball screw sleeve 74. An insertion hole that mates with the insertion rod 75 is opened on the upper outer wall of the rotating shaft 8. The insertion rod 75 is movably inserted into the insertion hole.

[0034] Two sets of symmetrical positioning rods 77 are fixedly provided on the outer wall of the rotating shaft 8. The lower end of the mounting frame 71 is provided with positioning holes that cooperate with the positioning rods 77, and the positioning rods 77 are movably inserted into the positioning holes.

[0035] After drying, the nut 12 can be unscrewed from the top of the bolt 10. Then, the sleeves 11 at both ends of the cover 2 can be slid upwards along the bolt 10 to remove the cover 2 from the top of the drying cylinder 1, making it easier to pour out the dried calcium carbonate inside the drying cylinder 1 for storage. The rotating shaft 8 and the stirring blade 9 can then be removed from the drying cylinder 1. Next, the worm gear 76 is rotated to drive the worm wheel 73 to rotate, and the worm wheel 73 drives the double-acting screw 72 to rotate. The two sets of ball screw sleeves 74 move away from each other, and the insertion rod 75 is pulled out from the insertion hole on the upper outer wall of the rotating shaft 8. Then, the rotating shaft 8 is slid downwards along the mounting port 78 to remove the rotating shaft 8 from the mounting port 78. Remove the shaft from the mounting port 78 to complete the disassembly of the mounting frame 71 and the rotating shaft 8. This allows for separate cleaning and maintenance of the rotating shaft 8 and the stirring blade 9, preventing excessive calcium carbonate buildup on the upper part of the rotating shaft 8 and the stirring blade 9 from affecting the subsequent stirring effect after prolonged use. After cleaning, align the positioning rods 77 at both ends of the rotating shaft 8 with the positioning holes at the lower end of the mounting frame 71 and insert them. Fully insert the rotating shaft 8 into the mounting port 78. At this time, rotate the worm gear 76, and the two sets of ball screw sleeves 74 will drive the insertion rods 75 to move closer to each other. Insert the insertion rods 75 into the insertion holes of the rotating shaft 8 to complete the installation of the rotating shaft 8.

[0036] The remaining structure is the same as that in Example 1.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
