Description

Technical Field

[0001] This utility model relates to the technical field of plastic modified granule sorting equipment, specifically a sorting device for processing plastic modified granules. Background Technology

[0002] Plastic modified granules are granular materials obtained by improving and enhancing the original properties of general-purpose plastics or engineering plastics through physical, chemical, or a combination of both methods. The main purpose of sorting plastic modified granules is to accurately separate mixed granules, remove granules that do not meet production requirements, ensure the uniformity of granules in the same batch, thereby improving product quality and reducing the difficulty and cost of subsequent processing.

[0003] Traditional sorting devices often only sort based on a single factor (such as size) and cannot comprehensively consider multiple factors, resulting in inconsistent quality of the sorted modified plastic particles, which cannot meet the requirements of high-precision sorting. For example, in the prior art, there is a vibration sorting device for automotive modified plastic particles disclosed in Chinese patent application number CN202420590674.0.

[0004] Therefore, we need to propose a sorting device for processing modified plastic granules. Utility Model Content

[0005] The purpose of this invention is to provide a sorting device for processing modified plastic granules, which integrates particle size screening and density sorting functions. It performs secondary sorting of granules of the same size based on density differences, changing the status quo of traditional devices that rely on single-factor sorting. This makes the sorted granules more uniform in terms of particle size and density, meeting the requirements of high-precision sorting, improving product quality, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sorting device for processing modified plastic granules, comprising: A base plate, on which supports are symmetrically arranged; The conveying chamber is located directly above the base plate. The conveying chamber is supported by a bracket. A feed inlet is provided on one side of the top of the conveying chamber, and a coarse material outlet is provided on one end of the conveying chamber. A conveying mechanism is provided inside the conveying chamber. The conveying mechanism includes a conveying auger, which is rotatably installed inside the conveying chamber. The spiral blades of the conveying auger are clearance-fitted with the inner wall of the conveying chamber. The sorting mechanism is located at the bottom of the conveying chamber. The sorting mechanism includes a front notch and a rear notch arranged sequentially in the material conveying direction. A first filter plate for filtering finer particles is installed in the front notch, and a second filter plate for filtering coarser particles is installed in the rear notch. When the conveying auger conveys the particles, the finer particles are sorted out when passing through the front notch, and the coarser particles are sorted out when passing through the rear notch.

[0007] Preferably, the conveying chamber is cylindrical, and both the first filter plate and the second filter plate are flush with the inner wall of the conveying chamber and are arc-shaped.

[0008] Preferably, it also includes a motor, which is installed on the outer wall of one end of the conveying chamber. The motor is connected to one end of the shaft of the conveying auger through a coupling to provide power to the conveying auger.

[0009] Preferably, it also includes a brush edge, which is disposed inside the conveying chamber. The brush edge is distributed along the edge of the spiral blade of the conveying auger, and the brush of the brush edge is in contact with the inner wall of the conveying chamber. When the conveying auger conveys the material, the brush edge can brush the particles out from the first filter plate and the second filter plate to avoid clogging.

[0010] Preferably, it also includes receiving hoppers, with two sets respectively located at the bottom of the front and rear notches. The upper parts of the two sets of receiving hoppers respectively surround the front and rear notches. The lower part of the receiving hopper is conical, and the bottom of the receiving hopper is provided with a first discharge port. A container corresponding to the first discharge port is placed on the bottom plate for receiving and discharging the particles at the sorting point to avoid particle splashing and scattering.

[0011] Preferably, it also includes a second discharge port, which is set on the inner wall of one side of the receiving hopper. A container corresponding to the second discharge port is placed on the bottom plate. A blower hood opposite to the second discharge port is embedded in the inner wall of the other side of the receiving hopper. An air duct is provided on the outer wall of the blower hood for connecting to the air outlet of the blower. The blower hood and the second discharge port are used together to perform secondary sorting of particles of the same size at the sorting point in terms of density.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Integrating particle size screening and density sorting functions, the device first performs preliminary sorting of particles of different sizes through the first and second filter plates. Then, by using the combination of the blower and the second discharge port, particles of the same size are sorted a second time based on density differences. This changes the traditional device's single-factor sorting, making the sorted particles more uniform in terms of particle size and density, meeting the requirements of high-precision sorting and improving product quality.

[0015] 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.

[0016] Please see Figure 1-3 This utility model provides a technical solution: A sorting device for processing modified plastic granules, comprising: Base plate 1, on which supports 2 are symmetrically arranged; The conveying chamber 3 is located directly above the base plate 1. The conveying chamber 3 is supported by the bracket 2. The top side of the conveying chamber 3 is provided with a feed inlet 4, and one end face of the conveying chamber 3 is provided with a coarse material outlet 12. The conveying chamber 3 is horizontally mounted on the support frame 2. The feed inlet 4 on one side of the top is used to feed in the plastic modified granules to be sorted, and the granules fall into the chamber by gravity. The coarse material outlet 12 on one end is used to discharge larger granules that have not passed through the sorting filter plate. The conveying chamber 3 works in conjunction with the conveying auger 5. When the conveying auger 5 rotates, it drives the granules to move along the axial direction of the chamber. As the main cavity for granule conveying and sorting, it limits the movement space of the granules, so that the granules pass through the sorting mechanism in an orderly manner during the conveying process, realizing the separation of granules of different specifications. At the same time, the setting of the feed inlet 4 and the coarse material outlet 12 clearly defines the material's entry and exit path, ensuring the continuity of the sorting process.

[0017] Please see Figure 2 : The conveying mechanism is located inside the conveying chamber 3. The conveying mechanism includes a conveying auger 5, which is rotatably installed inside the conveying chamber 3. The spiral blades of the conveying auger 5 are fitted with the inner wall of the conveying chamber 3 with a clearance. The shaft of the conveying auger 5 is rotatably mounted inside the conveying chamber 3 via bearings. The motor 6 drives the shaft to rotate via a coupling, causing the spiral blades to rotate synchronously. The spiral blades maintain a small gap with the inner wall of the conveying chamber 3. When the auger rotates, the thrust of the spiral blades pushes the particles axially along the conveying chamber 3, causing the particles to pass sequentially through the front notch 7 and the rear notch 9 of the sorting mechanism.

[0018] The above technical solution enables continuous and stable conveying of particles, providing power for the sorting process and allowing particles to pass through the sorting area at a controllable speed and trajectory, ensuring the accuracy and efficiency of sorting; the clearance fit design avoids friction between the spiral blades and the bin wall, reducing equipment wear and extending service life.

[0019] Please see Figure 2 : The sorting mechanism is located at the bottom of the conveying chamber 3. The sorting mechanism includes a front notch 7 and a rear notch 9 arranged sequentially in the material conveying direction. A first filter plate 8 for filtering finer particles is installed in the front notch 7, and a second filter plate 10 for filtering coarser particles is installed in the rear notch 9. When the conveying auger 5 conveys the particles, the finer particles are sorted out when passing through the front notch 7, and the coarser particles are sorted out when passing through the rear notch 9.

[0020] At the bottom of the conveying chamber 3, a front notch 7 and a rear notch 9 are sequentially arranged along the material conveying direction. The first filter plate 8 installed in the front notch 7 has smaller mesh sizes, while the second filter plate 10 installed in the rear notch 9 has larger mesh sizes. When the conveying auger 5 pushes the particles forward, finer particles with a diameter smaller than the mesh size of the first filter plate 8 fall below through the first filter plate 8, while particles with a diameter between the mesh sizes of the first and second filter plates continue to move forward and are separated by the second filter plate 10. The remaining larger particles are discharged from the coarse material outlet 12.

[0021] The above technical solution achieves preliminary particle sorting based on particle size differences, separating particles of different sizes to meet the needs of particle size classification, providing a foundation for subsequent finer sorting or processing, and improving the consistency of product specifications.

[0022] The pore sizes of the first filter plate 8 and the second filter plate 10 are selected according to actual needs.

[0023] For a preferred implementation, please refer to Figure 2The conveying chamber 3 is cylindrical, and both the first filter plate 8 and the second filter plate 10 are flush with the inner wall of the conveying chamber 3 and are arc-shaped. The cylindrical design of the conveying chamber 3, with the first filter plate 8 and the second filter plate 10 being arc-shaped and flush with the inner wall of the conveying chamber 3, ensures smooth flow within the conveying chamber 3, preventing particles from getting stuck or accumulating due to abrupt changes in the shape of the chamber wall during transport. The arc-shaped filter plates fit snugly against the chamber wall, ensuring that particles can pass smoothly through the filter plates for sorting. This optimizes the particle transport and sorting path, reduces particle resistance within the chamber, and improves transport efficiency. It also ensures a seamless connection between the filter plates and the chamber wall, preventing particles from accumulating in gaps and improving the integrity and accuracy of sorting.

[0024] For a preferred implementation, please refer to Figure 1-2 It also includes a motor 6, which is installed on the outer wall of one end of the conveying chamber 3. The motor 6 is connected to one end of the shaft of the conveying auger 5 through a coupling to provide power to the conveying auger 5.

[0025] The motor 6 is fixedly installed on the outer wall of one end of the conveying chamber 3 and rigidly connected to the shaft of the conveying auger 5 via a coupling. After the motor 6 is powered on, it converts electrical energy into mechanical energy, driving the shaft to rotate at a set speed, thereby driving the conveying auger 5 to work. It provides a stable power source for the conveying auger 5 and is the power core of the entire conveying and sorting process. Its speed can be adjusted according to actual production needs to control the conveying speed and sorting efficiency of the particles, ensuring the stability and reliability of the device operation.

[0026] For a preferred implementation, please refer to Figure 2 It also includes a brush edge 11, which is set inside the conveying chamber 3. The brush edge 11 is distributed along the edge of the spiral blade of the conveying auger 5. The brush of the brush edge 11 is in contact with the inner wall of the conveying chamber 3. When the conveying auger 5 conveys the material, the brush edge 11 can brush the particles off the first filter plate 8 and the second filter plate 10 to avoid clogging.

[0027] The brush edges 11 are distributed along the edge of the spiral blades of the conveying auger 5, and the brushes are in close contact with the inner wall of the conveying chamber 3. When the conveying auger 5 rotates, the brush edges 11 move synchronously, and the brushes continuously sweep across the surfaces of the first filter plate 8 and the second filter plate 10; timely removing particles stuck on the filter plates, preventing particles from accumulating and clogging the filter plate mesh, ensuring the permeability of the filter plates, maintaining the smooth operation of the sorting process, reducing downtime for cleaning due to filter plate clogging, and improving the continuous working capacity and production efficiency of the equipment.

[0028] For a preferred implementation, please refer to Figure 1-3It also includes receiving hoppers 13, of which two sets are provided and respectively located at the bottom of the front notch 7 and the rear notch 9. The upper parts of the two sets of receiving hoppers 13 surround the front notch 7 and the rear notch 9, respectively. The lower part of the receiving hopper 13 is conical. The bottom of the receiving hopper 13 is provided with a first discharge port 14. A container corresponding to the first discharge port 14 is placed on the bottom plate 1 for receiving and discharging the particles at the sorting point to avoid particle splashing and scattering.

[0029] Two sets of receiving hoppers 13 are placed at the bottom of the front notch 7 and the rear notch 9, respectively. The upper part is funnel-shaped and surrounds the notch to facilitate the collection of particles falling from the filter plate. The lower part is a conical structure, which allows the particles to slide naturally to the first discharge port 14 at the bottom and fall into the corresponding container for collection.

[0030] The above technical solution enables precise collection of sorted particles, preventing them from splashing and scattering during the fall and maintaining a clean working environment. At the same time, the orderly receiving and unloading process facilitates the classification, storage, and subsequent processing of particles of different specifications, improving the convenience of material management and the standardization of production.

[0031] For a preferred implementation, please refer to Figure 3 It also includes a second discharge port 17, which is set on the inner wall of one side of the receiving hopper 13. A container corresponding to the second discharge port 17 is placed on the bottom plate 1. A blower hood 15 opposite to the second discharge port 17 is embedded on the inner wall of the other side of the receiving hopper 13. An air duct 16 is provided on the outer wall of the blower hood 15 for connecting the air outlet of the blower. The blower hood 15 and the second discharge port 17 are used together to perform secondary sorting of particles of the same size at the sorting point in terms of density.

[0032] The second discharge port 17 is located on one inner wall of the receiving hopper 13, and the opposite inner wall is fitted with a blower hood 15, which is connected to the blower outlet via an air duct 16. After the blower is started, the generated airflow enters the blower hood 15 through the air duct 16 and is blown out of the blower hood 15 at a certain speed, acting on the particles in the receiving hopper 13. Particles with lower density are blown up by the airflow and fall into the corresponding container through the second discharge port 17, while particles with higher density remain in the receiving hopper 13 and are discharged from the first discharge port 14.

[0033] The above technical solution enables secondary sorting of particles of the same size that have already been sorted by particle size, based on density differences. This achieves comprehensive sorting by multiple factors, further improving the purity and quality of the particles, meeting the requirements for high-precision sorting, and broadening the application range of the device, making it suitable for production scenarios with high requirements for particle quality.

[0034] The wind power provided by the fan can be adjusted according to actual needs. The fan can be purchased from the market or online and is a mature existing product, so it will not be described in detail here.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
