Description

Technical Field

[0001] The invention belongs to the technical field of colloid drying, and in particular relates to a special colloid drying machine. Background Art

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

[0003] Existing colloid-specific dryers require the colloid to be placed on a conveyor belt and carried into the dryer via the conveyor belt for drying. However, colloid materials are usually sticky and easily adhere to the conveyor belt, resulting in some materials not being completely dried or being lost. This phenomenon not only affects production efficiency, but may also lead to material waste and increase costs. In addition, due to the characteristics of the colloid, the heat received by the colloid material is uneven during the movement of the conveyor belt. Some colloids may not be completely dried due to too short a residence time or uneven heat source. Some areas may receive too much or too little heat, which affects the drying effect. As a result, some colloids may not be 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 disadvantages of the above-mentioned prior art and provide a special colloid dryer.

[0005] The technical solution adopted to solve the above technical problems is: a colloid-specific dryer, including a drying box, the interior of which is a hollow structure, and slots are opened on both sides of the drying box, and a drying unit is installed on the top of the drying box. A heat-promoting efficiency component is installed inside the drying box to allow the colloid to contact the heat source generated by the drying unit in a short time, thereby shortening the drying time;

[0006] The heat-efficiency-promoting component includes a mesh disk, and a No. 2 connecting block is fixedly connected at the center of both sides of the mesh disk. At the same time, the No. 2 connecting block is slidably connected with two sliding rods on the side facing the mesh disk. The bottom end of the sliding rod is fixedly connected to the No. 1 connecting block, and the top of the No. 1 connecting block is fixedly connected to a spring with a semi-arc structure. At the same time, the end of the spring away from the No. 1 connecting block is located inside the No. 2 connecting block and is fixedly connected to it, which is used for continuous flipping and movement of the colloid during the drying process to reduce the accumulation and compaction of the colloid inside the mesh disk.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Furthermore, the second bevel gear rod is rotatably connected to the drying box body, and the second bevel gear rod is transmission-connected to the first bevel gear rod at one end away from the first bevel gear, and the bevel gears at both ends of the first bevel gear rod are in the same direction, and the first bevel gear rod is rotatably connected to the drying box body.

[0015] Furthermore, motors are installed on both sides of the outer wall of the drying box, and the output end of the motor is rotatably connected to the drying box body. At the same time, the through end of the motor is fixedly connected to the first bevel gear rod. The first bevel gear rod is transmission-connected to the second bevel gear at one end away from the second bevel gear rod, and the second bevel gear is rotatably connected to the drying box body.

[0016] Through the above technical solution, the colloidal material can continuously change its spatial position in the mesh disk during the reciprocating motion, which can avoid material accumulation or density, maintain the gaps between the materials, enable hot air to circulate more smoothly, improve the penetration of hot air, and thus improve the drying efficiency.

[0017] Furthermore, the drying box is fixedly connected to a No. 3 sprocket on the side away from the No. 2 bevel gear, and the No. 3 sprocket is rotatably connected to a No. 3 rotating plate on the side away from the drying box, while the other end of the No. 3 rotating plate is rotatably connected to a No. 4 sprocket, and a No. 2 chain is transmission-connected between the No. 4 sprocket and the No. 3 sprocket.

[0018] Through the above technical solution, by moving alternately 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.

[0019] Furthermore, the No. 2 bevel gear connecting shaft is rotatably connected to the drying box and the No. 3 sprocket, and the No. 2 bevel gear connecting shaft has a through-end fixedly connected to the No. 3 rotating plate. The No. 3 rotating plate is rotatably connected to the No. 4 rotating plate on the other side of the connection with the No. 4 sprocket, and the No. 4 rotating plate is rotatably connected to the support rod at one end away from the No. 3 rotating plate, and the other end of the support rod is fixedly connected to the No. 1 connecting block. The No. 4 sprocket connecting shaft is rotatably connected to the No. 3 rotating plate, and the No. 4 sprocket connecting shaft has a through-end fixedly connected to the No. 4 rotating plate.

[0020] The above technical solution can make the colloidal material spread more evenly during the drying process, avoiding uneven distribution of the material on the mesh plate due to gravity or humidity, and helping operators to better control the drying process and optimize production arrangements.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention drives the first bevel gear rod to transmit through the operation of the motor, and then drives the second bevel gear rod and the second bevel gear to rotate at the same time, and drives the second rotating plate to rotate, so that the other end of the second rotating plate drives the connecting rod to move back and forth in the linear direction in the drying box, and drives the third rotating plate to rotate with the connection point as the origin, and simultaneously drives the fourth sprocket to move, and under the action of the second chain, the fourth sprocket rotates, and then drives the fourth rotating plate to rotate, so that the top assembly of the support rod moves back and forth in the drying box, thereby making the net disk move back and forth in the drying box, so that the colloid can move back and forth between the heat source area and the normal temperature area, so that the colloid material can be evenly exposed to the heat source and normal temperature environment, avoiding local overheating or overcooling, and ensuring the uniformity of the drying process;

[0022] (2) The present invention can drive the circular plate to rotate synchronously by rotating the connecting rod, thereby pushing the T-shaped plate to move upward. After 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, thereby causing the mesh disk to vibrate elastically in the vertical direction. The elastic vibration can effectively shake the colloidal material off the surface of the mesh disk, prevent adhesion or agglomeration between the colloidal particles, help maintain the looseness of the material, ensure that each colloidal particle can evenly contact the heat source, and improve the drying effect.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0033] like Figure 1-Figure 7 The embodiment shows a colloid-specific dryer, comprising a drying box 11, the interior of the drying box 11 is a hollow structure, and slots 12 are provided on both sides of the drying box 11, and a drying unit 13 is installed on the top of the drying box 11. A heat-promoting 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, thereby shortening the drying time. The heat-promoting efficiency component 2 comprises a mesh disk 213. Before drying the colloid, the mesh disk 213 is located at the slot 12 on one side of the drying box 11, which is convenient for the staff to pour the colloid into the mesh disk 213 for drying, and a No. 2 connecting block 222 is fixedly connected to the center of both sides of the mesh disk 213. The No. 2 connecting block 222 is fixedly connected to the center of the two sides of the mesh disk 213. The connecting block 222 is fixedly connected to a T-shaped plate 223 on the side away from the mesh disk 213. In the heat source area, the colloid can be exposed to air with a higher temperature, which accelerates the evaporation of water. 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. Through the alternation of the heat source and normal temperature areas, water evaporation is more efficient and the drying process is accelerated. The T-shaped plate 223 is slidingly connected to a circular plate 220 at one end away from the second connecting block 222. A connecting rod 210 is fixedly connected to the eccentric part of the circular plate 220, and one end of the connecting rod 210 is rotatably connected to the first connecting block 219. At the same time, the connecting rod 210 is fixedly connected to the second rotating plate 29 at one end away from the circular plate 220.

[0034] like 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.

[0035] like Figure 2-Figure 8The output end of the motor 21 is connected to the drying box body 11 through rotation, and the through end of the motor 21 is fixedly connected to the first bevel gear rod 22, and the first bevel gear rod 22 is transmission-connected to the second bevel gear rod 23 at one end thereof, and the second bevel gear 211 connecting shaft is connected to the drying box body 11 and the third sprocket 214 through rotation, and the through end of the second bevel gear 211 connecting shaft is fixedly connected to the third rotating plate 217, and the other side of the connection between the third rotating plate 217 and the fourth sprocket 215 is rotationally connected to the fourth rotating plate 218, and the fourth rotating plate 218 is rotationally connected to the support rod 212 at one end away from the third rotating plate 217, and the other end of the support rod 212 is fixedly connected to the first connecting block 219, and the drying box body 11 is fixedly connected to the third sprocket 214 at one side away from the second bevel gear 211, and The third sprocket 214 is rotatably connected to the third rotating plate 217 on the side away from the drying box 11. At the same time, the other end of the third rotating plate 217 is rotatably connected to the fourth sprocket 215. During the reciprocating motion, the colloidal material can continuously change its spatial position in the mesh disk 213. This can avoid material accumulation or density, maintain the gaps between the materials, allow hot air to circulate more smoothly, improve the penetration of hot air, and thus improve the drying efficiency. The connecting shaft of the fourth sprocket 215 is rotatably connected to the third rotating plate 217, and the connecting shaft of the fourth sprocket 215 is fixedly connected to the fourth rotating plate 218. The fourth sprocket 215 and the third sprocket 214 are transmission-connected by the second chain 216, and the second bevel gear 211 is rotatably connected to the drying box 11, and the bevel gears at both ends of the first bevel gear rod 22 are in the same direction.

[0036] like Figure 3-Figure 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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, thereby causing the network disk 213 to vibrate elastically in the vertical direction.

[0041] As a result, as the colloid moves back and forth following the mesh disk 213, the mesh disk 213 moves elastically up and down, vibrating the colloid, and then the drying unit 13 dries the colloid on the mesh disk 213, which can significantly improve the drying effect, promote uniform drying of the material, reduce material waste, improve drying efficiency, and help extend the service life of the equipment and reduce maintenance costs.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
