Abstract
Description
Technical Field
[0001] The present application relates to the technical field of material screening, and in particular to a material particle size screening device. Background Art
[0002] Due to the limitation of production process, the particle size of resin materials in the final product is not uniform and is mixed with a small amount of unformed strips. They need to be manually selected and screened before they can be bagged and packaged. Usually, a vibrating screener or a centrifugal screener is used to screen the resin materials. However, before using the vibrating screener for particle size screening, the unformed strips need to be manually selected to prevent the unformed strips from clogging the filter screen of the vibrating screener. Then, the materials of different particle sizes are screened layer by layer through filters of different mesh sizes. The manual selection process is time-consuming and labor-intensive, which reduces the efficiency of particle size screening and reduces the production cost. The production line cannot reach the designed state of automatic operation and is difficult to be used on a large scale. The resin material is high-temperature material when it just leaves the production line, and cooling measures such as cooling water are needed to cool the high-temperature material, resulting in the material entering the screening section being water-containing material. Before using the centrifugal screening machine for particle size screening, an air purge process needs to be added to dry the material to avoid uneven screening caused by the tension of the surface liquid during centrifugation. However, the air purge process extends the product production cycle and generates a large amount of chemical exhaust gas that cannot be directly discharged, increasing the operating load of subsequent environmental protection treatment equipment.

[0016] In one embodiment, the material particle size screening device further includes a distribution tray, and the distribution tray is provided with a plurality of distribution areas in sequence along the discharge direction of the discharge port, and different distribution areas correspond to materials of different particle sizes.
[0017] In the technical solution of the present application, the material particle size screening device includes a cooling box, a lifting mechanism, and an air separation mechanism. The cooling box is used to receive the material at the discharge mechanism. The cooling box can not only receive the material, but also cool the high-temperature material by arranging liquids such as water in the cooling box. The lifting mechanism includes a first material receiving port and a second material receiving port. The first material receiving port is arranged in the cooling box, and the material is lifted from the first material receiving port to the second material receiving port. The high-temperature material cooled in the cooling box enters the lifting mechanism from the first material receiving port and is lifted to the second material receiving port. The lifting mechanism can also drain the material while lifting the material.

The first air blowing channel is configured for airflow to blow along an upward slant, which can blow the height of the material higher, making the material more obviously affected by gravity in the air blowing process, which helps to evenly distribute the material, effectively improving the efficiency of the particle size screening process of the resin material and reducing the load.

[0030] See Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of an embodiment of a material particle size screening device 1000 of the present application. Figure 2 for Figure 1A partially enlarged structural diagram. A material particle size screening device 1000 proposed in this application includes a cooling box 100, a lifting mechanism 200 and an air separation mechanism 300. The cooling box 100 is used to receive materials at the discharge mechanism. The cooling box 100 can not only receive materials, but also cool high-temperature materials by arranging liquids such as water in the cooling box 100. The lifting mechanism 200 includes a first material receiving port 210 and a second material receiving port 220. The first material receiving port 210 is arranged in the cooling box 100, and the material can be lifted from the first material receiving port 210 to the second material receiving port 220. The high-temperature material that has been cooled in the cooling box 100 enters the lifting mechanism 200 from the first material receiving port 210 and is lifted to the second material receiving port 220. The lifting mechanism 200 can also drain the material while lifting the material. By controlling the lifting power of the lifting mechanism 200, the drainage time of the material on the lifting mechanism 200 can be controlled to ensure that the material is in a dry state when it reaches the second material receiving port 220, which is convenient for the subsequent air separation process.
[0031] The air separation mechanism 300 includes a discharge port 310 and a first air blowing channel 320. The discharge port 310 is connected to the second material receiving port 220 so that the material can be transported from the second material receiving port 220 to the discharge port 310. The first air blowing channel 320 is disposed below the discharge port 310 and is configured to blow air diagonally upwards, away from the discharge port 310. After the dry material is transported to the discharge port 310, materials of different particle sizes have different weights. Under the action of the air blowing in the first air blowing channel 320, materials with relatively large particle sizes will fall closer to the discharge port 310, while materials with relatively large particle sizes will fall farther away from the discharge port 310, thereby allowing materials of different particle sizes to be screened. The first air blowing channel 320 is configured to blow air diagonally upwards, which can blow the material up, making the material more significantly affected by gravity during the air blowing process, facilitating uniform material separation, effectively improving the efficiency of the resin material particle size screening process, and reducing the load.
[0032] Further, see Figure 2 The air separation mechanism 300 further includes a second air blowing channel 330, which is disposed below the first air blowing channel 320. The second air blowing channel 330 is configured to blow air horizontally toward a side away from the discharge port 310. The horizontal blowing of the second air blowing channel 330 can expand the horizontal distribution range of the material, thereby facilitating uniform screening of the material.
[0033] Specifically, see Figure 3 , Figure 3The structure diagram of the air separation mechanism 300 is shown. The first air blowing channel 320 includes a plurality of first air jets arranged in an array, and the second air blowing channel 330 includes a plurality of second air jets arranged in an array. The first air jet and / or the second air jet are connected to a pneumatic blowing device to eject compressed air outward. For example, the pneumatic blowing device is an air pump 340, and the air source pressure is 0.6 MPa. The first air jet includes a first nozzle 321, and the jet angle of the first nozzle 321 is set along the upper side (such as Figure 2 The second jet pipe includes a second nozzle 331, and the jet angle of the second nozzle 331 is set along the horizontal direction (as shown by the arrow A). Figure 2 The first nozzle 321 and / or the second nozzle 331 each include a nozzle knob, which can be used to adjust the spray range of the first nozzle 321 and / or the second nozzle 331. The spray angle of the first nozzle 321 and / or the second nozzle 331 is adjustable, and the specific spray angle is determined according to actual application and is not specifically limited here.
[0034] The air separation mechanism 300 also includes multiple first air regulating valves, each of which is correspondingly disposed on the multiple first air injection pipes and configured to adjust the air intake of the first air injection pipes. The air separation mechanism 300 also includes multiple second air regulating valves, each of which is correspondingly disposed on the multiple second air injection pipes and configured to adjust the air intake of the second air injection pipes to control the distribution range of the material and ensure uniform particle size screening.
[0035] See Figure 1 For example, the lifting mechanism 200 includes a chain plate conveyor 230, which includes inclined chain plates. The material is lifted on the chain plates from the first receiving port 210 to the second receiving port 220. The lifting mechanism 200 also includes a water receiving support plate, which is arranged below and parallel to the chain plates. One end of the water receiving support plate is arranged in the cooling box 100. The water receiving support plate is used to receive water drained from the material during the draining process and allows the drained water to flow back into the cooling box 100 for cooling the material.
[0036] The connection method between the first receiving port 210 of the chain conveyor 230 and the cooling box 100 can be a detachable connection method such as threaded connection and clamping, or a non-detachable connection method such as welding, which is not specifically limited here. For example, in order to facilitate the manufacture of the material particle size screening device 1000, the connection method between the first receiving port 210 of the chain conveyor 230 and the cooling box 100 is welding. The connection method between the second receiving port 220 of the chain conveyor 230 and the air separation mechanism 300 is set with reference to the above-mentioned connection method and will not be repeated here. For example, a bolt hole is reserved at the screening head where the discharge port 310 is located, and the second receiving port 220 of the chain conveyor 230 is connected to the discharge port 310 through the bolt hole, which is convenient for quick disassembly and maintenance.
[0037] See Figure 1 and Figure 4 , Figure 4 The schematic diagram of the structure of the distribution tray 400 is shown. The material particle size screening device 1000 also includes a distribution tray 400, which is sequentially provided with multiple distribution areas along the discharge direction of the discharge port 310, and different distribution areas correspond to materials with different particle sizes. For example, the distribution tray 400 is sequentially provided with a first distribution area 410, a second distribution area 420, and a third distribution area 430 along the discharge direction of the discharge port 310. The first distribution area 410 is used to receive heavy materials with large particle sizes, the second distribution area 420 is used to receive materials with a particle size range of 3mm-5mm, and the third distribution area 430 is used to receive materials with a particle size range of less than 3mm.
[0038] The cooling box 100 of the material particle size screening device 1000 can be directly connected to the material discharge mechanism. No additional manual operation is required except for device maintenance. Under the operation process of continuous transportation by the lifting mechanism 200 and continuous ejection of materials by the air separation mechanism 300, the materials will not accumulate, effectively improving the overall production efficiency of the production line. The material particle size screening device 1000 is powered by the compressed air of the air separation mechanism 300, and a lifting and drainage stage is provided at the front end to ensure that the material reaching the air separation mechanism 300 can remain dry, avoiding the material screening being affected by the surface tension of the liquid. Under the dual effects of ejection of materials at the discharge port 310 and spraying by the air separation mechanism 300, the materials are evenly distributed when they fall to the ground, meeting normal production needs.
[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
