Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board preparation technology, and specifically to a flow-forming device for calcium silicate board preparation. Background Technology

[0002] Calcium silicate board is a board made by using loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials and siliceous and calcareous materials as the main binding materials. It is made by pulping, molding, and accelerating the curing reaction in high temperature and high pressure saturated steam to form calcium silicate gel.

[0003] Utility model patent CN215702849U discloses an automated pulping equipment for calcium silicate board production, including a worktable with support legs at the bottom, a transport component on the top surface of the worktable, a mold on the transport component, and a mounting frame above the worktable. The mounting frame is connected to the worktable via support columns, and a mounting plate connects the mounting frame to a mixing tank. In this prior art pulping equipment, when in use, the pulp dripping onto the conveyor belt tends to overflow to both sides, causing waste. Furthermore, the dripping from the hopper onto the conveyor belt is relatively concentrated and uneven.

[0004] Therefore, there is still room for improvement in existing technologies. Utility Model Content

[0005] In order to solve the problems in the existing technology that the slurry dripping onto the conveyor belt tends to overflow to both sides of the conveyor belt, causing waste, and that the dripping position from the hopper onto the conveyor belt is relatively concentrated and not uniform, this utility model provides a slurry preparation device for calcium silicate board.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A slurry preparation device for calcium silicate board includes a frame, a conveyor belt on the frame, the conveyor belt being driven by a motor, a fixed support fixed on the frame, a slurry hopper fixed on the fixed support, and the outlet of the slurry hopper being located above the conveyor belt; the frame is provided with an anti-overflow mechanism and a leveling mechanism, which are respectively arranged corresponding to the upper surface of the conveyor belt.

[0008] According to the above scheme, the anti-overflow mechanism includes a bidirectional screw, a movable block, an anti-overflow strip, and a drive assembly. Two movable blocks are threaded to both ends of the bidirectional screw, and an anti-overflow strip is fixed on each of the two movable blocks. The two anti-overflow strips are slidably connected to the upper surface of the conveyor belt. The bidirectional screw is driven to rotate by the drive assembly, so that the bidirectional screw drives the two movable blocks to move the two anti-overflow strips closer to the middle or separate them to the sides.

[0009] According to the above scheme, the two anti-overflow strips are spaced apart and parallel to each other along the conveyor belt conveying direction, and the discharge port of the slurry bin is located above the conveyor belt between the two anti-overflow strips.

[0010] According to the above scheme, the drive assembly includes a turntable 5 and a rocker arm. The rocker arm is fixed to one side of the turntable, and the other side of the turntable is fixedly connected to one end of a bidirectional screw.

[0011] According to the above scheme, the rocker arm is fixed at a position near the outer edge of the turntable, the center of the rocker arm is eccentrically set with the center of the turntable, and the center of the turntable is coaxially set with the center of the bidirectional screw.

[0012] According to the above scheme, the bidirectional screw is rotatably mounted on the fixed bracket, and one end of the bidirectional screw passes through the fixed bracket and is fixedly connected to the turntable.

[0013] According to the above scheme, a guide block is fixed on the inner wall of the fixed bracket, and two limiting grooves are formed on the guide block. Guide strips are formed on the upper ends of the two moving blocks, and the guide strips of the two moving blocks are slidably connected to the two limiting grooves respectively.

[0014] According to the above scheme, the leveling mechanism is located on one side of the anti-overflow mechanism. The leveling mechanism includes a fixed plate, a threaded shaft, a connecting block, and a scraper. The fixed plate is fixed on the fixed bracket. The upper end of the threaded shaft is threadedly connected to the fixed plate. The lower end of the threaded shaft is fixedly connected to the connecting block. The connecting block is fixedly connected to the scraper. The lower end of the scraper is correspondingly set to the upper surface of the conveyor belt, and the width of the scraper is the same as the width of the conveyor belt.

[0015] According to the above scheme, an internal threaded sleeve is installed on the fixing plate, the internal threaded sleeve is threadedly connected to the threaded shaft, and a guide component is provided between the fixing plate and the connecting block.

[0016] According to the above scheme, the guide assembly includes several guide rods fixed on the connecting block and several guide holes provided on the fixed plate, with the guide rods and guide holes slidably connected.

[0017] The beneficial effects of this utility model are:

[0018] This invention features an anti-overflow mechanism on the frame. During use, the slurry for making calcium carbonate boards is first loaded into the slurry hopper. During operation, the valve at the slurry hopper's outlet is opened, allowing the slurry to fall onto the surface of the conveyor belt. The anti-overflow mechanism prevents the slurry from overflowing to the sides of the conveyor belt, thus avoiding waste. Furthermore, a leveling mechanism on the frame levels the slurry during transport, resulting in a more uniform flow and ensuring consistent thickness of the subsequent calcium carbonate boards.

[0025] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 4 As shown, the present invention discloses a slurry preparation device for calcium carbonate boards, comprising a frame 1, a conveyor belt 2 driven by a motor 7, a fixed bracket 3 fixed on the frame 1, and a slurry hopper 4 fixed on the fixed bracket 3, with the outlet of the slurry hopper 4 located above the conveyor belt 2; the frame 1 is equipped with an anti-overflow mechanism 5 and a leveling mechanism 6, which are respectively positioned corresponding to the upper surface of the conveyor belt 2. This configuration, with the anti-overflow mechanism 5 on the frame 1, allows the slurry for making calcium carbonate boards to be loaded into the slurry hopper 4 during use. During operation, the valve of the outlet of the slurry hopper 4 is opened, allowing the slurry to fall onto the upper surface of the conveyor belt 2. The anti-overflow mechanism 5 prevents the slurry from overflowing to both sides of the conveyor belt 2, thus preventing waste. The leveling mechanism 6 on the frame 1 levels the slurry during transport, making the slurry flow more uniform and ensuring consistent thickness of the subsequent calcium carbonate boards.

[0027] Furthermore, the anti-overflow mechanism 5 includes a bidirectional screw 51, movable blocks 52, anti-overflow strips 53, and a drive assembly. Two movable blocks 52 are threaded to both ends of the bidirectional screw 51, and anti-overflow strips 53 are fixed to each of the two movable blocks 52. The two anti-overflow strips 53 are slidably connected to the upper surface of the conveyor belt 2. The bidirectional screw 51 is driven to rotate by the drive assembly, causing the two movable blocks 52 to move the two anti-overflow strips 53 closer together or apart. This configuration, with the two anti-overflow strips 53 acting as a barrier, prevents the slurry from overflowing to both sides of the conveyor belt 2. The bidirectional screw 51 can be rotated by the drive assembly, causing the two movable blocks 52 to move the two anti-overflow strips 53 closer together or apart, thereby adjusting the spacing between the two anti-overflow strips 53. This allows for adjustment of the width of the slurry dripping onto the conveyor belt 2, increasing its applicability.

[0028] In practical applications, the two anti-overflow strips 53 abut against the upper surface of the conveyor belt 2, providing a good anti-overflow effect.

[0029] Furthermore, the two anti-overflow strips 53 are spaced apart and parallel to each other along the conveying direction of the conveyor belt 2, and the discharge port of the slurry bin 4 is located above the conveyor belt 2 between the two anti-overflow strips 53. This arrangement ensures that when the slurry falls through the discharge port, it lands on the conveyor belt 2 between the two anti-overflow strips 53, and is thus blocked by the two anti-overflow strips 53.

[0030] Furthermore, the drive assembly includes a turntable 54 and a rocker arm 55. The rocker arm 55 is fixed to one side of the turntable 54, and the other side of the turntable 54 is fixedly connected to one end of the bidirectional screw 51. With this configuration, rotating the rocker arm 55 drives the turntable 54 to rotate, which in turn drives the bidirectional screw 51 to rotate, causing the two moving blocks 52 to move the two anti-overflow strips 53 closer together or further apart.

[0031] Furthermore, the rocker arm 55 is fixed to the turntable 54 near its outer edge, with the center of the rocker arm 55 eccentrically positioned relative to the center of the turntable 54. The center of the turntable 54 is coaxially positioned with the center of the bidirectional screw 51. This configuration allows the turntable 54 to rotate relative to its center when the rocker arm 55 is rotated, making rotation easier.

[0032] Furthermore, the bidirectional screw 51 is rotatably mounted on the fixed bracket 3, and one end of the bidirectional screw 51 extends out of the fixed bracket 3 and is fixedly connected to the turntable 54. This arrangement places the turntable 54 and the rocker arm 55 outside the fixed bracket 3, making operation more convenient.

[0033] Furthermore, a guide block 57 is fixed on the inner wall of the fixed bracket 3. Two limiting grooves 58 are formed on the guide block 57, and guide strips 56 are formed on the upper ends of the two moving blocks 52. The guide strips 56 of the two moving blocks 52 are slidably connected to the two limiting grooves 58 respectively. In this configuration, the limiting grooves 58 serve to guide the guide strips 56 and limit their stroke.

[0034] Furthermore, the leveling mechanism 6 is located on one side of the anti-overflow mechanism 5. The leveling mechanism 6 includes a fixed plate 61, a threaded shaft 63, a connecting block 64, and a scraper 65. The fixed plate 61 is fixed to the fixed bracket 3. The upper end of the threaded shaft 63 is threadedly connected to the fixed plate 61, and the lower end of the threaded shaft 63 is fixedly connected to the connecting block 64. The connecting block 64 is fixedly connected to the scraper 65. The lower end of the scraper 65 is correspondingly arranged on the upper surface of the conveyor belt 2, and the width of the scraper 65 is the same as the width of the conveyor belt 2. With this arrangement, the scraper 65 can level the slurry during the conveying process. The rotatable threaded shaft 63 drives the connecting block 64 and the scraper 65 to rise and fall, thereby adjusting the distance between the scraper 65 and the conveyor belt 2 to adjust the thickness of the slurry. The width of the scraper 65 is the same as the width of the conveyor belt 2 so that the scraper 65 can cover the width of the conveyor belt 2, resulting in a more thorough leveling effect.

[0035] In practical applications, the scraper 65 is fitted with a clearance fit to the upper surface of the conveyor belt 2.

[0036] Furthermore, an internal threaded sleeve 62 is installed on the fixing plate 61, and the internal threaded sleeve 62 is threadedly connected to the threaded shaft 63. A guide assembly is provided between the fixing plate 61 and the connecting block 64.

[0037] Furthermore, the guiding assembly includes several guide rods 66 fixed to the connecting block 64 and several guide holes provided on the fixing plate 61, with the guide rods 66 slidably connected to the guide holes. This configuration ensures that when the connecting block 64 is adjusted to rise or fall, the connecting block 64 drives the scraper 65 to rise or fall vertically, resulting in a more stable lifting effect.

[0038] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
