Description

Technical Field

[0001] The present invention belongs to the technical field of colloid drying, and particularly relates to a special drying machine for colloids. Background Art

[0002] Colloidal substances are substances composed of fine particles (such as colloidal particles, microparticles, etc.). These particles are usually suspended in a liquid and have strong dispersibility. These substances are often difficult to process during the drying process. Common problems include slow drying speed, caking, thermal sensitivity, etc. With the progress of industrial technology, especially in industries such as pharmaceuticals, food, and chemicals, the application of colloidal substances has gradually increased, and the market requirements for colloid drying technology have become increasingly stringent. As a device that can meet special drying needs, a special drying machine for colloids is not only to solve the problem of drying colloidal substances, but also to adapt to the changing industrial needs, improve production efficiency, ensure product quality, and promote the development trends of environmental protection and energy conservation.

[0003] Existing special drying machines for colloids need to place the colloid on a conveyor belt and transport it into the drying machine through the conveyor belt for drying. However, colloidal materials are usually sticky and prone to adhering to the conveyor belt, resulting in some materials not being completely dried or being lost. This phenomenon not only affects production efficiency but also may lead to material waste and increased costs. Moreover, due to the characteristics of colloids, during the movement of the conveyor belt, the heat received by the colloidal material is uneven. Some colloids may not be completely dried due to too short residence time or uneven heat source. Some areas receive too much or too little heat, thus affecting the drying effect, and further resulting in some colloids not being fully dried, affecting the quality of the final product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a special drying machine for colloids.

[0005] The technical solution adopted to solve the above technical problem is: a special drying machine for colloids, including a drying box body. The interior of the drying box body is provided with a hollow structure, and through slots are opened on both sides of the drying box body. At the same time, a drying unit is installed on the top of the drying box body. A heat promotion efficiency component is installed inside the drying box body to enable the colloid to contact the heat source generated by the drying unit in a short time and shorten the drying time. The heat promotion efficiency component includes a wire mesh tray. At the center of both sides of the wire mesh tray, there are fixedly connected second connecting blocks. At the same time, two sliding rods penetrate and slide on the side of the second connecting block facing the wire mesh tray. The bottom end of the sliding rod is fixedly connected with a first connecting block. The top of the first connecting block is fixedly connected with a spring arranged in a semi-circular structure. At the same time, the end of the spring away from the first connecting block is located inside the second connecting block and fixedly connected thereto, so as to continuously turn over and move the colloid during the drying process, reducing the accumulation and compaction of the colloid inside the wire mesh tray.

[0006] Through the above technical solution, in the heat source area, the colloid can be exposed to air with higher temperature, which accelerates the evaporation of water, while in the normal temperature area, the colloid is cooled and relieved to a certain extent, thereby avoiding the damage to the material structure caused by excessive temperature. By alternating between the heat source and normal temperature areas, water evaporation is more efficient and the drying process is accelerated.

[0007] Furthermore, the second connecting block is fixedly connected to a T-shaped plate on the side away from the network disk, and the T-shaped plate is slidably connected to a circular plate on the end away from the second connecting block. A connecting rod is fixedly connected to the eccentric part of the circular plate, and one end of the connecting rod is rotatably connected to the No. 1 connecting block. At the same time, the connecting rod is fixedly connected to the No. 2 rotating plate on the end away from the circular plate.

[0008] Through the above technical solution, the colloidal material is not easily adhered to the mesh disk due to vibration during the drying process, which reduces the waste and downtime caused by material adhesion, helps to improve material transfer efficiency, and reduces equipment maintenance costs.

[0009] Furthermore, the other end of the No. 2 turn plate is rotatably connected to the No. 1 turn plate, and the No. 1 turn plate and the No. 2 turn plate connection end are rotatably connected to the No. 2 sprocket, the No. 2 sprocket connecting shaft is rotatably connected to the No. 1 turn plate, and the No. 2 sprocket connecting shaft is fixedly connected to the No. 2 turn plate at the through end, and the No. 2 sprocket connecting shaft is fixedly connected to the No. 2 turn plate, the No. 1 turn plate is rotatably connected to the No. 1 sprocket at one end away from the No. 2 turn plate, and the No. 2 sprocket and the No. 1 sprocket are transmission-connected with a No. 1 chain, and the No. 1 sprocket is fixedly connected to the drying box body at the side away from the No. 1 turn plate.

[0010] Through the above technical solution, vibration can increase the contact area between the colloid and the hot air, prompting the moisture in the colloid material to evaporate faster. Through continuous vibration, the surface of the colloid is more easily exposed to the hot air, thereby improving the drying efficiency and shortening the drying time.

[0011] Furthermore, the drying box body is rotatably connected to the side of the No. 1 bevel gear away from the No. 1 sprocket, and the No. 1 bevel gear connecting shaft is rotatably connected to the drying box body and the No. 1 sprocket, and at the same time, the through end of the No. 1 bevel gear connecting shaft is fixedly connected to the No. 1 rotating plate, and one side of the No. 1 bevel gear is transmission-connected to the second bevel gear rod, and the bevel gears at both ends of the second bevel gear rod are mirror-imaged.

[0012] Through the above technical solution, the linear reciprocating motion can make the colloidal material fully contact the heat source in a short time, shorten the drying time, and improve the overall efficiency of the production line. Multiple passes through the drying area can greatly accelerate the drying process, thereby increasing the production capacity of the equipment.

[0013] Further, the second bevel gear rod is rotatably connected through the drying box body. One end of the second bevel gear rod away from the first bevel gear is drivingly connected with a first bevel gear rod, and the bevel gear directions at both ends of the first bevel gear rod are the same. At the same time, the first bevel gear rod is rotatably connected through the drying box body.

[0014] Further, motors are installed on both sides of the outer wall of the drying box body, and the output ends of the motors are rotatably connected through the drying box body. At the same time, the penetrating ends of the motors are fixedly connected with the first bevel gear rod. One end of the first bevel gear rod away from the second bevel gear rod is drivingly connected with a second bevel gear, and the second bevel gear is rotatably connected with the drying box body.

[0015] Through the above technical solution, during the reciprocating movement of the colloidal material, the spatial position in the mesh tray can be continuously changed, which can avoid the accumulation or densification of the material, maintain the gaps between the materials, enable the hot air to flow more smoothly, improve the penetrability of the hot air, and thus enhance the drying efficiency.

[0016] Further, a third sprocket is fixedly connected to one side of the drying box body away from the second bevel gear. A third rotating plate is rotatably connected to one side of the third sprocket away from the drying box body. At the same time, the other end of the third rotating plate is rotatably connected to a fourth sprocket, and a second chain is drivingly connected between the fourth sprocket and the third sprocket.

[0017] Through the above technical solution, by alternatingly moving between the heat source area and the normal temperature area, the colloid can absorb and release heat in the most suitable environment, which can accelerate the evaporation rate of water and reduce the drying time required.

[0018] Further, the connecting shaft of the second bevel gear is rotatably connected through the drying box body and the third sprocket. The penetrating end of the connecting shaft of the second bevel gear is fixedly connected with the third rotating plate. The other side of the connection between the third rotating plate and the fourth sprocket is rotatably connected to a fourth rotating plate. One end of the fourth rotating plate away from the third rotating plate is rotatably connected to a support rod, and the other end of the support rod is fixedly connected with a first connecting block. The connecting shaft of the fourth sprocket is rotatably connected through the third rotating plate, and the penetrating end of the connecting shaft of the fourth sprocket is fixedly connected with the fourth rotating plate.

[0019] Through the above technical solution, the colloidal material can be spread more evenly during the drying process, avoiding uneven distribution of the material on the mesh tray due to gravity or humidity effects, which helps the operator better control the drying process and optimize the production arrangement.

[0020] The beneficial effects of the present invention are as follows: (1) By the operation of the motor, the first bevel gear rod is driven for transmission, and then the second bevel gear rod and the second bevel gear are driven to rotate simultaneously, driving the second rotating plate to rotate. As a result, while the other end of the second rotating plate pushes the connecting rod to move back and forth in the linear direction inside the drying box, it drives the connecting rod to rotate itself, and drives the third rotating plate to rotate with its connection point as the origin, synchronously driving the fourth sprocket to move. Under the action of the second chain, the fourth sprocket rotates itself, and then drives the fourth rotating plate to rotate, enabling the top component of the support rod to move back and forth inside the drying box, so that the mesh tray moves back and forth inside the drying box. This allows the colloid to move back and forth between the heat source area and the normal temperature area, enabling the colloid material to be evenly exposed to the heat source and normal temperature environment, avoiding local overheating or overcooling, and ensuring the uniformity of the drying process; (2) By the rotation of the connecting rod, the circular plate can be driven to rotate synchronously, thus pushing the T-shaped plate to move upward. When the circular plate rotates one circle, under the action of the spring, the second connecting block moves downward in the linear direction of the sliding rod, and then the mesh tray vibrates elastically in the vertical direction. The elastic vibration can effectively shake off the colloid material from the surface of the mesh tray, prevent adhesion or caking between colloid particles, help maintain the looseness of the material, ensure that each colloid particle can evenly contact the heat source, and improve the drying effect.

Detailed implementation mode

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The inside of the drying box 11 is arranged as a hollow structure, and notch 12 is penetrated and opened on both sides of the drying box 11. At the same time, a drying unit 13 is installed on the top of the drying box 11. A heat promotion efficiency component 2 is installed inside the drying box 11, which is used for the colloid to contact the heat source generated by the drying unit 13 in a short time, shortening the drying time. The heat promotion efficiency component 2 includes a wire mesh tray 213. Before drying the colloid, the wire mesh tray 213 is located at the notch 12 on one side of the drying box 11, which is convenient for staff to pour the colloid into the wire mesh tray 213 for drying. And second connecting blocks 222 are fixedly connected to the centers of both sides of the wire mesh tray 213, and a T-shaped plate 223 is fixedly connected to the side of the second connecting block 222 away from the wire mesh tray 213. In the heat source area, the colloid can contact higher-temperature air, accelerating the evaporation of moisture. While in the normal-temperature area, the colloid is cooled and relieved to a certain extent, thus avoiding the damage to the material structure caused by too high temperature. Through the alternation of the heat source and the normal-temperature area, the evaporation of moisture is more efficient, the drying process is accelerated, and one end of the T-shaped plate 223 away from the second connecting block 222 is slidably connected to a circular plate 220. An eccentric part of the circular plate 220 is penetrated and fixedly connected with a connecting rod 210, and one end of the connecting rod 210 is rotatably connected to a first connecting block 219. At the same time, a second rotating plate 29 is fixedly connected to the end of the connecting rod 210 away from the circular plate 220.

[0025] As Figures 1 - 8As shown, the other end of the No. 2 rotating plate 29 is rotatably connected to the No. 1 rotating plate 28, and one side of the connecting end of the No. 1 rotating plate 28 and the No. 2 rotating plate 29 is rotatably connected to the No. 2 sprocket 27, the connecting shaft of the No. 2 sprocket 27 is rotatably connected to the No. 1 rotating plate 28, and the connecting shaft of the No. 2 sprocket 27 is fixedly connected to the No. 2 rotating plate 29, the end of the No. 1 rotating plate 28 away from the No. 2 rotating plate 29 is rotatably connected to the No. 1 sprocket 25, and the side of the drying box 11 away from the No. 1 sprocket 25 is rotatably connected to the No. 1 bevel gear 24. Due to the vibration during the drying process, the colloidal material is not easy to adhere to the net disk 213, which reduces the waste and shutdown problems caused by material adhesion, helps to improve the material transfer efficiency, and reduces equipment maintenance costs. , and the No. 1 bevel gear 24 connecting shaft is rotatably connected to the drying box 11 and the No. 1 sprocket 25. At the same time, the No. 1 bevel gear 24 connecting shaft is fixedly connected to the No. 1 rotating plate 28. One side of the No. 1 bevel gear 24 is transmission-connected with the second bevel gear rod 23. The second bevel gear rod 23 is rotationally connected to the drying box 11. The second bevel gear rod 23 is transmission-connected with the first bevel gear rod 22 at one end away from the No. 1 bevel gear 24. Vibration can enhance the contact area between the colloid and the hot air, and promote the faster evaporation of moisture in the colloid material. Through continuous vibration, the surface of the colloid is more easily exposed to the hot air, thereby improving the drying efficiency and shortening the drying time. Motors 21 are installed on both sides of the outer wall of the drying box 11.

[0026] like Figures 2 - 8As shown, the output end of the motor 21 is rotatably connected to the drying box body 11 through penetration. At the same time, the penetrating end of the motor 21 is fixedly connected to the first bevel gear rod 22. One end of the first bevel gear rod 22 away from the second bevel gear rod 23 is drivingly connected to a second bevel gear 211. The connecting shaft of the second bevel gear 211 is rotatably connected to the drying box body 11 and the third sprocket 214 through penetration. And the penetrating end of the connecting shaft of the second bevel gear 211 is fixedly connected to the third rotating plate 217. On the other side of the connection between the third rotating plate 217 and the fourth sprocket 215, a fourth rotating plate 218 is rotatably connected. And one end of the fourth rotating plate 218 away from the third rotating plate 217 is rotatably connected to the support rod 212. At the same time, the other end of the support rod 212 is fixedly connected to the first connection block 219. On the side of the drying box body 11 away from the second bevel gear 211, a third sprocket 214 is fixedly connected. And on the side of the third sprocket 214 away from the drying box body 11, a third rotating plate 217 is rotatably connected. At the same time, the other end of the third rotating plate 217 is rotatably connected to a fourth sprocket 215. During the reciprocating movement of the colloid material, the spatial position in the mesh plate 213 can be continuously changed. In this way, the accumulation or densification of the material can be avoided, the gaps between the materials can be maintained, and the hot air can flow more smoothly, improving the penetration of the hot air, thereby enhancing the drying efficiency. The connecting shaft of the fourth sprocket 215 is rotatably connected to the third rotating plate 217 through penetration. And the penetrating end of the connecting shaft of the fourth sprocket 215 is fixedly connected to the fourth rotating plate 218. A second chain 216 is drivingly connected between the fourth sprocket 215 and the third sprocket 214. And the second bevel gear 211 is rotatably connected to the drying box body 11, and the bevel gear directions at both ends of the first bevel gear rod 22 are the same.

[0027] As Figures 3 - 8It is shown that at the same time, the first bevel gear rod 22 is rotatably connected to the drying box body 11, and the bevel gears at both ends of the second bevel gear rod 23 are mirror-imaged, and the No. 2 sprocket 27 is transmission-connected to the No. 1 chain 26 between the No. 1 sprocket 25 and the No. 1 sprocket 25. By alternately moving between the heat source area and the normal temperature area, the colloid can absorb and release heat in the most suitable environment, which can accelerate the evaporation rate of water and reduce the time required for drying. At the same time, the No. 1 sprocket 25 is fixedly connected to the drying box body 11 away from the No. 1 rotating plate 28. At the same time, the No. 2 connecting block 222 is slidably connected to the side of the mesh disk 213 with two sliding rods 224. The linear reciprocating motion can make the colloid material fully contact the heat source in a short time, shorten the drying time, and improve production efficiency. The overall efficiency of the production line, multiple passes through the drying area can greatly accelerate the drying process, thereby improving the production capacity of the equipment, the bottom end of the slide rod 224 is fixedly connected to the No. 1 connecting block 219, and the top of the No. 1 connecting block 219 is fixedly connected to a spring 221 with a semi-arc structure, which can make the colloid material more evenly spread during the drying process, avoiding the uneven distribution of the material on the mesh disk 213 due to gravity or humidity, and helping operators to better control the drying process and optimize production arrangements. At the same time, the spring 221 is away from the No. 1 connecting block 219. The end is located inside the No. 2 connecting block 222 and is fixedly connected to it, which is used for the colloid to continuously flip and move during the drying process, reducing the accumulation and compaction of the colloid inside the mesh disk 213.

[0028] The working principle of this embodiment is as follows: the staff can put the colloid into the mesh disk 213 from the slot 12 on one side of the drying box 11, and then the motors 21 on both sides of the drying box 11 will start to drive the first bevel gear rod 22 to transmit, and then simultaneously drive the second bevel gear rod 23 and the second bevel gear 211 to rotate.

[0029] When the second bevel gear rod 23 rotates, it drives the first bevel gear 24 to transmit, so that the first rotating plate 28 rotates with the connection point with the first sprocket 25 as the origin, thereby making the second sprocket 27 move synchronously with the first rotating plate 28 and rotate under the action of the first chain 26. When the second sprocket 27 rotates, it drives the second rotating plate 29 to rotate, so that the other end of the second rotating plate 29 drives the connecting rod 210 to rotate while pushing the connecting rod 210 to move back and forth in the linear direction in the drying box 11.

[0030] When the second bevel gear 211 rotates, it drives the third rotating plate 217 to rotate with its connection as the origin, and synchronously drives the fourth sprocket 215 to move. Under the action of the second chain 216, the fourth sprocket 215 rotates, and then drives the fourth rotating plate 218 to rotate, so that the top assembly of the support rod 212 moves back and forth in the drying box 11, thereby causing the net disk 213 to move back and forth in the drying box 11.

[0031] When the connecting rod 210 rotates, it can drive the circular plate 220 to rotate synchronously, thereby pushing the T-shaped plate 223 to move upward. After the circular plate 220 rotates one circle, under the action of the spring 221, the second connecting block 222 moves downward in the linear direction of the sliding rod 224, and then the mesh plate 213 vibrates elastically in the vertical direction.

[0032] Thus, when the colloid moves back and forth following the mesh plate 213, the mesh plate 213 moves elastically up and down to vibrate the colloid. Then, the drying unit 13 dries the colloid on the mesh plate 213, which can significantly improve the drying effect, promote the uniform drying of the material, reduce material waste, improve the drying efficiency, and help extend the service life of the equipment and reduce the maintenance cost.

[0033] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
