Description

Technical Field

[0001] This invention relates to the field of plastic pellet processing technology, specifically to a plastic pellet drying and filtering device. Background Technology

[0002] Plastic granules refer to granular plastics. Common types of plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. During the production process, plastic granules generally undergo a basic granulation step. The plastic granules produced in this process usually contain moisture, so they must be dried. Also, because the granulated granules are often of different sizes, they need to be filtered and screened before they can be packaged or used.

[0003] Patent application CN202311609341.4 discloses a plastic particle drying and filtering device, including a shell, a support frame, a bottom plate, a top cover plate, a mounting frame, and rollers. A feeding hopper is located on one side of the shell, and a lifting assembly and a filter element are located inside the shell. A discharge trough is located at the center of the bottom of the shell, and a discharge component is installed inside the feeding hopper. An installation port is located at the center of the top of the top cover plate, and a hot air fan is installed at the top of the installation port. A rotating component is installed at the bottom of the shell. The filter gap formed between two adjacent arc-shaped plates can filter plastic particles, and the distance between the two adjacent arc-shaped plates can be adjusted in actual operation, thus allowing for the filtering of plastic particles of different sizes. The rotating frame and the corner plate both lift the plastic particles, and the scraper teeth on the corner plate can clean the filter gap between the two adjacent arc-shaped plates, preventing plastic particles from clogging.

[0004] The existing equipment has a low degree of automation. It can only operate the next batch after the previous batch of plastic particles has been completely processed, resulting in low production efficiency and significant waiting time, which is not conducive to achieving continuous production and large-scale processing needs. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a plastic particle drying and filtering device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plastic particle drying and filtering device, comprising a shell, a support fixedly connected to the bottom of the shell, a partition fixedly connected to the inner wall of the shell, a first guide plate fixedly connected to the inner wall of the shell, a second guide plate fixedly connected to the inner wall of the shell, a screening mechanism fixedly connected to the bottom of the shell, and a transport mechanism fixedly connected to the inner wall of the shell. By setting up the transport mechanism and adopting a continuous processing method in an assembly line manner, the plastic particles maintain orderly flow during the conveying process, avoiding material accumulation and process interruption, improving the continuity and overall efficiency of processing, facilitating seamless connection of subsequent drying and screening processes, and effectively improving the overall working capacity of the machine.

[0007] The screening mechanism includes: The second outer frame has its outer wall fixedly connected to the outer shell, and a screening plate is fixedly connected to its inner wall. A second guide frame is fixedly connected to the bottom of the screening plate. The screening mechanism is divided into three groups, with different spacing between the screening plates in each group. This is used to screen plastic particles of different sizes. By setting up the screening mechanism and adopting a multi-stage screening structure, the different spacing between the screening plates in each group can simultaneously classify and screen plastic particles of different sizes. This ensures screening accuracy while maintaining the continuous operation of the production line, avoiding material congestion caused by a single screening process, and enhancing the stability of the screening process.

[0008] According to the above technical solution, a connecting frame is fixedly connected to the outer wall of the shell, a first motor is fixedly connected to the outer wall of the connecting frame, and a second motor is fixedly connected to the outer wall of the shell. The first motor is used to drive the screening mechanism to operate, while the second motor is used to drive the transport mechanism to operate.

[0009] According to the above technical solution, a transport device is fixedly connected to the bottom of the outer shell, and a baffle is fixedly connected to the top of the transport device. The transport device is used to transport plastic particles screened by the screening mechanism.

[0010] According to the above technical solution, a top plate is fixedly connected to the top of the outer shell, a feed port is opened on the top of the top plate, and a drying device is fixedly connected to the top of the top plate. The feed port is used for putting in plastic particles, and the drying device is used for drying the plastic particles on the transport mechanism.

[0011] According to the above technical solution, a first outer frame is fixedly connected to the bottom of the outer shell, and a storage box is movably connected to the inner wall of the first outer frame. The storage box is used to store plastic particles that have not passed through the screening mechanism. By setting up the storage box, plastic particles that are too large can be collected in a concentrated manner to avoid them from being mixed into subsequent processes and affecting product quality. At the same time, it is convenient for unified recycling or reprocessing, reducing material waste and improving the convenience of the production process.

[0012] According to the above technical solution, the inner wall of the outer shell is rotatably connected to a rotating shaft via a bearing, the output end of the first motor is fixedly connected to the rotating shaft, and a rotating blade is fixedly connected to the outer wall of the rotating shaft. The first motor drives the rotating blade to rotate via the rotating shaft.

[0013] According to the above technical solution, the transport mechanism includes a third outer frame, the outer wall of which is fixedly connected to the outer shell, and a through plate fixedly connected to the inner wall of which is a plurality of through plates. The multiple through plates are arranged at equal intervals inside the third outer frame. By setting up the transport mechanism, when transporting plastic particles, the accumulated material is not directly carried away as a whole. Instead, it is transported in layers and batches by means of the cooperation between the push rod and the through plates, so that the plastic particles are evenly spread out during the transport process, thereby improving the drying effect and avoiding the problem of insufficient drying caused by material stacking.

[0014] According to the above technical solution, the inner wall of the outer shell is rotatably connected to a drive shaft via a bearing, the output end of the second motor is fixedly connected to the drive shaft, a conveyor belt is sleeved on the outer wall of the drive shaft, and a push rod is fixedly connected to the outer wall of the conveyor belt, wherein the push rod extends from the gap between multiple through plates to the top of the through plates.

[0015] Compared with the prior art, the present invention provides a plastic particle drying and filtering device, which has the following beneficial effects: 1. By setting up a transport mechanism and adopting a continuous processing method in an assembly line manner, the present invention ensures that plastic particles always flow in an orderly manner during the transport process, avoiding material accumulation and process interruption, improving the continuity and overall efficiency of processing, facilitating the seamless connection of subsequent drying and screening processes, and effectively improving the working capacity of the whole machine.

[0016] 2. By setting up a screening mechanism and adopting a multi-stage screening structure, the present invention can simultaneously classify and screen plastic particles of different sizes by setting up a screening mechanism with different spacing between each set of screening plates. While ensuring screening accuracy, it can maintain the continuous operation of the production line, avoid material congestion caused by a single screening process, and enhance the stability of the screening process.

[0017] 3. By setting up a transport mechanism, the present invention avoids directly carrying away the accumulated material as a whole when transporting plastic particles. Instead, it relies on the cooperation of the push rod and the through plate to transport the material in layers and batches, so that the plastic particles are evenly spread out during the transport process, thereby improving the drying effect and avoiding the problem of insufficient drying caused by material stacking.

[0018] 4. By setting up a storage box, this invention can collect excessively large plastic particles in a centralized manner, preventing them from being mixed into subsequent processes and affecting product quality. At the same time, it facilitates unified recycling or reprocessing, reduces material waste, and improves the convenience of the production process. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example 1: See Figures 1-3The present invention provides a technical solution: a plastic particle drying and filtering device, comprising a shell 1, a support 102 fixedly connected to the bottom of the shell 1, a partition 104 fixedly connected to the inner wall of the shell 1, a first guide plate 103 fixedly connected to the inner wall of the shell 1, a second guide plate 105 fixedly connected to the inner wall of the shell 1, a screening mechanism 2 fixedly connected to the bottom of the shell 1, a transport mechanism 3 fixedly connected to the inner wall of the shell 1, a connecting frame 1011 fixedly connected to the outer wall of the shell 1, a first motor 1012 fixedly connected to the outer wall of the connecting frame 1011, and a... The second motor 1013 is used to drive the screening mechanism 2, while the first motor 1012 drives the conveying mechanism 3. A conveying device 101 is fixedly connected to the bottom of the outer casing 1, and a baffle 1014 is fixedly connected to the top of the conveying device 101. The conveying device 101 is used to transport the plastic particles screened by the screening mechanism 2. A top plate 108 is fixedly connected to the top of the outer casing 1, and a feed inlet 109 is provided on the top of the top plate 108. A drying device 1010 is fixedly connected to the top of the top plate 108. The feed inlet 109 is used to dry the plastic particles. The plastic particles are fed into the conveying mechanism 3, and the drying device 1010 is used to dry the plastic particles on the conveying mechanism 3. The bottom of the outer shell 1 is fixedly connected to the first outer frame 106, and the inner wall of the first outer frame 106 is movably connected to the storage box 107, which is used to store plastic particles that have not passed through the screening mechanism 2. During operation, the plastic particles to be processed are fed into the outer shell 1 through the feed port 109 and fall onto the conveying mechanism 3. Driven by the second motor 1013, the conveying mechanism 3 transports the plastic particles. During the transport process, the drying device 1010 on the top continuously dries the plastic particles. The plastic particles are dried to remove residual moisture from their surface. The dried plastic particles continue to move under the drive of the transport mechanism 3, and are guided by the first guide plate 103 and the partition plate 104 before falling into the screening mechanism 2 below. The first motor 1012 drives the screening mechanism 2 to classify and screen the plastic particles: plastic particles that meet the particle size requirements fall into the transport device 101 after passing through the screening mechanism 2 and are stably transported to the next process; while plastic particles that are too large to pass through the screening mechanism 2 are intercepted and collected in the storage box 107 for subsequent centralized processing.

[0025] Example 2: Please refer to Figures 4-8Based on Embodiment 1, the present invention provides a technical solution: the screening mechanism 2 includes: a second outer frame 201, the outer wall of the second outer frame 201 being fixedly connected to the outer shell 1, a screening plate 202 being fixedly connected to the inner wall of the second outer frame 201, and a second guide frame 203 being fixedly connected to the bottom of the screening plate 202. The screening mechanism 2 is divided into three groups, with different spacing between the screening plates 202 in each group, used for screening plastic particles of different sizes. A rotating shaft 204 is rotatably connected to the inner wall of the outer shell 1 via bearings. The output end of a first motor 1012 is fixedly connected to the rotating shaft 204, and a rotating blade 205 is fixedly connected to the outer wall of the rotating shaft 204. The first motor 1012 drives the rotating blade 205 to rotate via the rotating shaft 204. After the first motor 1012 starts, its output end drives the rotating shaft 204. 4. The rotating mechanism 3 drives the rotating blade 205 to rotate as well. The dried plastic particles fall into the three sets of screening mechanisms 2 in sequence under the drive of the transport mechanism 3. The spacing between the screening plates 202 in each set of screening mechanisms 2 is different, and the spacing is arranged in order from small to large. The plastic particles first enter the first set of screening mechanisms 2. The plastic particles with a particle size smaller than the spacing between the screening plates 202 in this set fall into the second guide frame 203 below through the screening plates 202 and are guided by the second guide frame 203 to the transport device 101 for collection. The larger plastic particles that fail to pass through the screening plates 202 in this set are pushed to the next set of screening mechanisms 2 by the action of the rotating blade 205, and are screened in sequence. The three sets of screening mechanisms 2 cooperate step by step to screen plastic particles of different particle size ranges, realizing multi-level grading of plastic particles. During rotation, the rotating blade 205 not only propels the material forward but also prevents plastic particles from accumulating or clogging on the screening plate 202, ensuring the continuity and stability of the screening process. Finally, all plastic particles that meet the particle size requirements of each grade fall into the corresponding conveying device 101 through the second guide frame 203, while plastic particles with a particle size larger than the spacing between all screening plates 202 are collected in the storage box 107, completing the entire grading and screening process.

[0026] The transport mechanism 3 includes a third outer frame 301, the outer wall of which is fixedly connected to the outer shell 1. Multiple through plates 302 are fixedly connected to the inner wall of the third outer frame 301, arranged equidistantly inside the third outer frame 301. A drive shaft 303 is rotatably connected to the inner wall of the outer shell 1 via bearings. The output end of a second motor 1013 is fixedly connected to the drive shaft 303. A conveyor belt 304 is fitted onto the outer wall of the drive shaft 303, and a push rod 305 is fixedly connected to the outer wall of the conveyor belt 304. The push rod 305 extends from the gaps between the multiple through plates 302 to the top of the through plates 302. After the second motor 1013 starts, its output end drives the drive shaft 303 to rotate, and the conveyor belt 304 is fitted onto the outer wall of the drive shaft 303. The conveyor belt 304 on the wall moves in a circular motion; plastic particles are fed into the feed port 109 and fall onto the top surface of the pass plate 302; driven by the conveyor belt 304, the push rod 305 moves in a circular motion along the gap between the pass plates 302 and continuously pushes the plastic particles located at the top of the pass plate 302 forward. Due to the spacing and height of the push rod 305, the plastic particles are not carried away all at once in a whole pile, but are gradually moved forward along the pass plate 302 in layers and batches under the intermittent pushing action of the push rod 305; when the plastic particles pass under the drying device 1010, because they are in a loose, single-layer or thin-layer state, the hot air or drying medium can fully contact the surface of each plastic particle, which significantly improves the drying efficiency.

[0027] When the transport mechanism 3 is working, the second motor 1013 drives the drive shaft 303 to rotate, thereby driving the conveyor belt 304 to move continuously. Several push rods 305 are fixed on the conveyor belt 304, arranged at certain intervals. The tip of each push rod 305 extends upward from the gap between two adjacent through plates 302. When the push rod 305 moves forward with the conveyor belt 304, its tip directly contacts the plastic particles accumulated on the through plates 302. It should be noted that the height of the push rod 305 is limited; it can only directly push the bottom layer of plastic particles and cannot push the entire pile of materials at once. All the particles; the upper particles mainly move by being driven by the lower particles and by the friction between the particles, but this driving force has a significant lag, which causes the pushed particles to continue moving forward through the plate 302, while the upper particles, having lost the support of the lower particles, fall directly onto the plate 302 under the action of gravity. Since the lower particles have already moved forward, the falling particles have no pushing force in front of them, and coupled with the friction on the surface of the plate 302, they remain in place. This cycle repeats, with each push rod 305 pushing the plastic particles within a certain range in front of it in turn, so that the particles are divided into several batches and moved forward one by one.
