Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ceramsite material processing equipment, specifically a ceramsite material drying and screening equipment. Background Technology
[0002] The shape of expanded clay varies depending on the process. Its surface is a hard outer shell, which is ceramic or glazed. This shell has the function of water and air insulation and gives the expanded clay high strength. After production, the expanded clay needs to be screened and dried to ensure its quality.
[0003] Because the existing ceramsite screening and drying are separate processes, not only are the procedures increased and production costs raised, but the drying effect is also unsatisfactory. Furthermore, drying particles of different sizes at the same temperature can easily cause small particles to be dried and deformed, making them unusable in subsequent operations. In addition, when screening ceramsite, traditional equipment often places the screening plate inside the screening equipment and pours the ceramsite onto the screening plate from the external feeding trough. This can easily cause the ceramsite to accumulate in certain areas of the screening screen, resulting in low utilization of the screen surface. This not only increases screening time but also leads to poor flowability of the accumulated material, making it difficult for the screening plate to screen, thus resulting in an insignificant screening effect. Utility Model Content

A screening plate is fixedly installed at the bottom of the drive plate. A filter port is opened at the bottom of the inner wall of the screening plate. A discharge box is fixedly installed at the bottom of the discharge box. A guide tube 1 is fixedly installed at the bottom of the discharge box. A guide tube 2 is fixedly installed on the outer wall of the screening plate.
[0006] As a preferred technical solution of this utility model: the servo motor and the drive motor are both electrically connected to the controller, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and the outer wall of the second gear meshes with the outer wall of the first gear.
[0007] As a preferred technical solution of this utility model: the inner wall of the circular block is in contact with the outer wall of the groove, the projected area of the discharge box is adapted to the projected area of the screening plate, and the projected area of the feeding trough is smaller than the projected area of the screening plate.
[0008] As a preferred technical solution of this utility model: there are two heating tubes, and the power of the two heating tubes is different. The power of the heating tube on the inner wall of the first rotating drum is less than the power of the heating tube on the inner wall of the second rotating drum. There are several filter ports, which are evenly distributed on the bottom of the inner wall of the sieve plate.
[0009] As a preferred technical solution of this utility model: there are two circular blocks, which are symmetrically distributed on both sides of the fixed cylinder; there are two gears; and the bottom of the discharge box is chamfered.
[0010] As a preferred technical solution of this utility model: the heating tube is electrically connected to the controller, there are two baffles, and the two baffles are symmetrically distributed on the inner wall of the fixed cylinder, the end of the first guide tube near the baffle is set as a corrugated pipe, one end of the first guide tube is connected to the bottom of the discharge box, and the other end of the first guide tube is located inside the first rotating cylinder, the end of the second guide tube near the screening plate is set as a corrugated pipe, one end of the second guide tube is connected to the outer wall of the screening plate, and the other end of the second guide tube is located inside the second rotating cylinder.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. In this ceramsite drying and screening equipment, when the operator feeds material from the feeding trough onto the screening plate, the controller sends a signal, and the drive motor receives the signal, causing the drive plate to slide on the outer wall of the screw. This allows the screening plate to move, improving the flowability of the material. Smaller materials can be quickly and smoothly screened from the filter port into the discharge box. At this time, the material on the screening plate can enter the interior of the rotating drum in a timely manner. By feeding material while moving the screening plate, the material moves on the screening plate, allowing it to be evenly distributed along the entire screen surface. This makes effective use of the screen surface, improving screening efficiency and significantly enhancing the screening effect.
[0013] 2. This ceramsite drying and screening equipment works by having the controller send a signal, which the servo motor receives, causing the servo motor to start working. This drives the worm gear to rotate, and the worm wheel meshing with it rotates. The gear coaxial with the worm wheel rotates synchronously, which in turn drives the rotating drum to rotate. At this time, the controller sends a signal to start the heating element. The small particles screened in the rotating drum can be dried at a low temperature, which can avoid damage to the material or even cracks caused by improper drying temperature or long drying time, thus affecting the strength and expansion performance of the ceramsite.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to the figure-- Figure 6 A drying and screening device for ceramsite aggregate includes a rotating drum 1. A fixed drum 2 is rotatably sleeved on the inner wall of the rotating drum 1. A rotating drum 2 3 is rotatably sleeved on the other end of the fixed drum 2. A fixed base 4 is fixedly installed at the bottom of the fixed drum 2. A base plate 5 is fixedly installed at the bottom of the fixed base 4. A servo motor 6 is installed on the top of the base plate 5. A support plate 10 is fixedly installed on the top of the base plate 5. A worm gear 7 is fixedly installed on the power output shaft of the servo motor 6. A rotating shaft 11 is rotatably connected to the inner wall of the support plate 10. A worm wheel 8 and a gear 9 are fixedly installed at both ends of the rotating shaft 11. Gear 2 12 is fixedly sleeved on the outer walls of both the rotating drum 1 and the rotating drum 2 3. A slot 13 is opened on the inner wall of both the rotating drum 1 and the rotating drum 2 3 near the end of the fixed drum 2. Circular... Heating tubes 15 are fixedly installed on the inner walls of the two rotating cylinders 1 and 3, which are away from the fixed cylinder 2. Baffles 16 are fixedly installed on the inner walls of both sides of the fixed cylinder 2. A feeding trough 17 is opened at the top of the fixed cylinder 2. A drive motor 18 is fixedly installed on the inner wall of the fixed cylinder 2. A screw 19 is fixedly installed on the power output shaft of the drive motor 18. A drive plate 20 is threadedly connected to the outer wall of the screw 19. The end of the screw 19 away from the drive motor 18 is rotatably sleeved on the inner wall of the fixed cylinder 2. A screening plate 21 is fixedly installed at the bottom of the drive plate 20. A filter port 22 is opened at the bottom of the inner wall of the screening plate 21. A discharge box 25 is fixedly installed at the bottom of the screening plate 21. A first guide tube 23 is fixedly installed at the bottom of the discharge box 25. A second guide tube 24 is fixedly installed on the outer wall of the screening plate 21.
[0023] In the above structure, by setting the bottom plate 5, the contact area between the drying device and the ground can be increased, so that the device can maintain a more stable state during operation. By setting the ends of the rotating drum 1 and the rotating drum 2 away from the fixed drum 2 to be rounded, the inner wall of the rotating drum 1 is inclined, which makes it easier for the material left on the inner wall of the end of the rotating drum 1 away from the fixed drum 2 to slide into the interior of the rotating drum 1.
[0024] In a preferred embodiment: both the servo motor 6 and the drive motor 18 are electrically connected to the controller, the outer wall of the worm 7 meshes with the outer wall of the worm wheel 8, and the outer wall of the second gear 12 meshes with the outer wall of the first gear 9.
[0025] In the above structure, by sending a signal to the controller, the servo motor 6 receives the signal, which allows the worm 7 to rotate and the worm wheel 8 meshing with it to rotate synchronously. The gear 9 coaxial with the worm wheel 8 can also rotate. By setting the outer wall of the gear 12 to mesh with the outer wall of the gear 9, when the gear 9 rotates, the gear 12 can rotate synchronously, thereby driving the drum 1 to rotate.
[0026] In a preferred embodiment: the inner wall of the circular block 14 fits against the outer wall of the slot 13, the projected area of the discharge box 25 is adapted to the projected area of the screening plate 21, and the projected area of the feeding trough 17 is smaller than the projected area of the screening plate 21.
[0027] In the above structure, by setting the inner wall of the slot 13 to fit against the outer wall of the circular block 14, when the fixed cylinder 2 remains stationary, only the rotating cylinder 1 rotates. This not only makes the rotating cylinder 1 rotate more smoothly, but also prevents the rotating cylinder 1 from separating from the fixed cylinder 2, thus avoiding the spillage of material inside the rotating cylinder 1 and the resulting waste. By making the projected area of the feeding trough 17 smaller than the projected area of the screening plate 21, the material entering the feeding trough 17 will not fall to the bottom of the fixed cylinder 2 when the screening plate 21 moves back and forth, thus preventing the material from not being screened and dried in time.
[0028] In a preferred embodiment: there are two heating tubes 15, and the power of the two heating tubes 15 is different. The power of the heating tube 15 on the inner wall of the first rotating drum 1 is less than the power of the heating tube 15 on the inner wall of the second rotating drum 3. There are several filter ports 22 and they are evenly distributed on the bottom of the inner wall of the sieve plate 21.
[0029] In the above structure, by setting multiple filter ports 22, smaller ceramsite particles can fall quickly and efficiently into the feeding tank 17 and be transported to the inside of the rotating drum 1 relatively quickly. The smaller particles can be dried. By setting two heating tubes 15 with different powers, larger particles in the rotating drum 2 can be dried at high temperature, ensuring that the large particles are fully dried. Small particles on the inner wall of the rotating drum 1 can be dried at low temperature, which can avoid damage to the ceramsite particles caused by high temperature and long-term drying, or even the appearance of network cracks, thereby affecting the strength and expansion performance of the ceramsite particles.
[0030] In a preferred embodiment: there are two circular blocks 14, which are symmetrically distributed on both sides of the fixed cylinder 2; there are two gears 12; and the bottom of the discharge box 25 is chamfered.
[0031] In the above structure, by setting two gears 12, when the two servo motors 6 start working at the same time, the first drum 1 and the second drum 3 can perform drying work at the same time, which can improve the drying efficiency. By setting the bottom of the discharge box 25 to be chamfered, the small particles inside the discharge box 25 can quickly and centrally fall into the first guide tube 23, thereby improving the drying efficiency of small particles.
[0032] In a preferred embodiment: the heating element 15 is electrically connected to the controller, there are two baffles 16, and the two baffles 16 are symmetrically distributed on the inner wall of the fixed cylinder 2. The first conduit 23 is corrugated at one end near the baffle 16, one end of the first conduit 23 is connected to the bottom of the discharge box 25, and the other end of the first conduit 23 is located inside the rotating cylinder 1. The second conduit 24 is corrugated at one end near the screening plate 21, one end of the second conduit 24 is connected to the outer wall of the screening plate 21, and the other end of the second conduit 24 is located inside the rotating cylinder 2 3.
[0033] In the above structure, by setting two baffles 16, the first rotating drum 1 and the second rotating drum 3 can be isolated, which can effectively prevent larger particles inside the second rotating drum 3 from mixing into the first rotating drum 1, thus preventing unsatisfactory drying effect. By setting the first guide tube 23 as a corrugated pipe at one end near the baffle 16, the first guide tube 23 can be contracted when the discharge box 25 moves, so as not to be damaged. At the same time, it can also transport small particles filtered into the filter port 22 to the inside of the first rotating drum 1, so that the small particles can be dried in time, effectively saving drying time and improving work efficiency. At this time, large particles inside the screening plate 21 can be transferred to the inside of the second rotating drum 3 through the second guide tube 24. By sending a signal through the controller, the materials inside the first rotating drum 1 and the second rotating drum 3 can be heated. In actual operation, the heating tube 15 can be set to different temperatures according to different materials to achieve reasonable and effective drying of the materials.
[0034] Working principle: When using this equipment, the operator can feed materials into the screening plate 21 through the feeding trough 17. By sending a signal to the controller and receiving the signal to the drive motor 18, the drive plate 20 can slide on the outer wall of the screw 19, thereby moving the screening plate 21. At this time, materials can be fed in while the screening plate 21 moves back and forth, allowing the materials to move on the screening plate 21 and disperse. The materials can be dispersed across the entire screen surface of the screening plate 21, preventing large clumps of material from accumulating and causing poor screening. When materials of different sizes need to be dried, the controller sends a signal, the servo motor 6 receives the signal, and the worm gear 7 rotates. The worm wheel 8 meshes with it and rotates synchronously. The gear 9 on the same shaft 11 as the worm wheel 8 also rotates synchronously. The gear 9 meshes with the gear 12 on the outer wall of the drum 1, thereby driving the drum 1 to rotate. At this time, the material inside the drum 1 can be rotated and dried, which can make the material have a larger contact area with the hot air, resulting in more thorough and uniform drying, thereby improving work efficiency.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
