Description

Technical Field

[0001] The utility model relates to the technical field of twin-screw granulators, in particular to a drying mechanism of a twin-screw granulator. Background Technique

[0002] A twin-screw granulator is a device for mixing and granulating materials. The materials are mixed, sheared and heated by two meshing screws, so as to realize the plasticization, melting and granulation of the materials.

[0003] At present, there is a problem that some particles are easy to stick together during the drying process in the existing twin-screw granulators;

[0004] The reason for this problem is that during the use of the twin-screw granulator, the materials need to be sent into the interior of the twin-screw granulator, and then the internal structure of the twin-screw granulator mixes, heats and fuses the materials. Then, the materials will grow into strip-shaped semi-finished products. The semi-finished products will be cooled in a water tank. At this time, a large amount of moisture will adhere to the outside of the semi-finished products. Finally, the semi-finished products will enter the interior of the cutting device for granulation treatment. After granulation, the particles need to be dried. To prevent the particles from melting and deforming during drying, a hot air box is mostly set above the drying device, and the warm air blown out by the hot air box is used to dry the particles. At this time, if the volume of the particles is small and there is moisture between two groups of particles, it will cause the two groups of particles to stick together, resulting in more moisture remaining between the two groups of particles. At this time, when the particles pass through the hot air area, the moisture between the two groups of particles cannot be completely dried by the hot air flow, resulting in the problem that there is still some moisture in the particle recovery after granulation processing. Therefore, we propose a drying mechanism of a twin-screw granulator. Content of the Utility Model

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0026] By providing a drying mechanism for a twin-screw granulator in the embodiments of this application, the problem that some particles are prone to sticking together during the drying process in existing twin-screw granulators is solved.

[0027] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0028] The embodiments of the present utility model disclose a binding device for file arrangement.

[0029] According to the attached Figures 1-6 As shown, it includes a twin-screw granulator main body 1. The twin-screw granulator main body 1 can refer to a twin-screw granulator of model Z5-433-25. A drying box 2 is provided on the side of the twin-screw granulator main body 1. A drying mechanism is provided inside the drying box 2. The drying mechanism includes a vibrating plate 201, which is movably arranged inside the drying box 2. A motor 204 is arranged on the side of the vibrating plate 201. The vibrating plate 201 is driven by the motor 204 to vibrate. A mesh plate 206 is installed outside the vibrating plate 201. The mesh plate 206 evacuates the particles under the drive of the vibrating plate 201. A spring 205 is arranged above the vibrating plate 201. The spring 205 buffers the movement of the vibrating plate 201 through its elastic force.

[0030] A partition plate 210 is fixedly connected inside the drying box 2. The vibrating plate 201 is slidably connected to the side of the partition plate 210. A connecting plate 209 is fixedly connected to the side of the vibrating plate 201. The connecting plate 209 is slidably connected inside the partition plate 210. An installation frame 208 is fixedly connected to the side of the partition plate 210. A limiting rod 207 is fixedly connected inside the installation frame 208. The spring 205 is movably sleeved outside the limiting rod 207. The connecting plate 209 is movably sleeved outside the limiting rod 207. The connecting plate 209 is slidably connected inside the installation frame 208. The spring 205 is fixedly connected to the upper surface of the connecting plate 209. The top end of the spring 205 is fixedly connected inside the installation frame 208.

[0031] A support frame 211 is fixedly connected to the side surface of the partition plate 210. The motor 204 is installed inside the support frame 211. A resisting block 203 is fixedly connected to the outer surface of the output end of the motor 204. A vibration block 202 is fixedly connected to the lower surface of the connecting plate 209. An auxiliary plate 215 is fixedly connected to the inner side wall of the drying box 2. A support rod 213 is fixedly connected to the outside of the auxiliary plate 215. A sliding plate 214 is fixedly connected to the side of the vibration plate 201 away from the connecting plate 209. The sliding plate 214 is movably sleeved on the outside of the support rod 213.

[0032] There are two groups of mesh plates 206. One group of mesh plates 206 is installed above the vibration plate 201, and the other group of mesh plates 206 is installed below the vibration plate 201. A baffle 212 is fixedly connected to the outer surface of the mesh plate 206 at the upper position of the vibration plate 201. The baffle 212 is movably inserted into the drying box 2. A hot air box 216 is installed on the inner top of the drying box 2. An inclined plate 218 is fixedly connected to the inside of the drying box 2. A discharge frame plate 217 is fixedly connected to the side of the drying box 2. The inclined plate 218 is fixedly connected to the side of the discharge frame plate 217.

[0033] The material is sent into the interior of the twin-screw granulator main body 1, and the materials are mixed, sheared, and heated by two mutually meshing screws. Then, the materials will form long-strip semi-finished products. The semi-finished products will be cooled through a water tank, and finally, the semi-finished products will enter the interior of the cutting device for granulation treatment.

[0034] After granulation processing, the particles enter the interior of the drying box 2 from the feed box on the side of the granulation device. Subsequently, the motor 204 is started through the operating device, causing the motor 204 to drive the abutting block 203 to rotate. When the protruding position outside the abutting block 203 is disengaged from the vibrating block 202 during rotation, it will push the vibrating block 202 upward, causing the vibrating block 202 to drive the connecting plate 209 upward. Subsequently, the connecting plate 209 will drive the vibrating plate 201 upward. While the connecting plate 209 moves upward, it will squeeze the spring 205 inside the mounting frame 208. At this time, the connecting plate 209 will also slide outside the limiting rod 207. At the same time, the sliding plate 214 will also move with the vibrating plate 201, causing the sliding plate 214 to slide outside the support rod 213. Subsequently, when the protruding position of the abutting block 203 leaves the outside of the vibrating block 202, the connecting plate 209 will lose the upward thrust and thus lose the squeezing force on the spring 205. At this time, the spring 205 will generate a tension force to push the connecting plate 209 downward, causing the connecting plate 209 to drive the vibrating plate 201 back to its original position. Repeating this process causes the connecting plate 209 and the vibrating plate 201 to move up and down, thereby causing the vibrating plate 201 to drive the mesh plate 206 to move up and down and vibrate. When the particles pass through the mesh plate 206, the particles will come into contact with the outside of the mesh plate 206. Under the vibration of the upper and lower two groups of mesh plates 206, the particles will vibrate, causing the particles to disperse. At the same time, through the two groups of mesh plates 206, the particles can be vibrated and dispersed twice, increasing the time for hot air flow. At the same time, it also prevents the particles from sticking together due to moisture, increasing the drying effect of the particles.

[0035] By driving the two groups of mesh plates 206 to vibrate with the vibrating plate 201, the two groups of mesh plates 206 disperse the particles under vibration, reducing the adhesion between the particles due to water molecules. At the same time, it increases the time for hot air flow and improves the drying efficiency of the particles.

[0036] The auxiliary plate 215 supports and connects the position of the support rod 213, and the support rod 213 supports and limits the other side of the vibrating plate 201. When the protruding block of the abutting block 203 leaves the outside of the vibrating block 202, the spring 205 can drive the connecting plate 209 back to its original position. The baffle 212 is arranged above the mesh plate 206 in the upper position. The baffle 212 shields the positions of the abutting block 203 and the support rod 213, preventing the particles from entering the positions between other structures.

[0037] In summary, compared with the prior art, the following beneficial effects are achieved:

[0038] After granulation processing, the particles enter the interior of the drying box 2 from the feed box on the side of the granulation device. Subsequently, the motor 204 is driven by the operating device to drive the abutting block 203 to rotate. During the rotation of the abutting block 203, the vibrating block 202 and the connecting plate 209 are driven to move upward. Subsequently, when the protruding position of the abutting block 203 leaves the outside of the vibrating block 202, the spring 205 will drive the connecting plate 209 back to the initial position without extrusion, so that the vibrating plate 201 drives the mesh plate 206 to move up and down and vibrate. When the particles pass through the mesh plate 206, the particles will come into contact with the outside of the mesh plate 206. Under the vibration of the upper and lower groups of mesh plates 206, the particles vibrate, so that the particles are dispersed. By driving the two groups of mesh plates 206 to vibrate with the vibrating plate 201, the two groups of mesh plates 206 disperse the particles twice under vibration, reduce the adhesion between the particles due to water molecules, and at the same time increase the time of hot air flow, improving the drying efficiency of the particles.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
