[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0027] like Figure 1-Figure 5 As shown, a plastic particle dust removal vibrating screen proposed in one embodiment of the present application includes a vibrating screen body 1, which is an existing linear vibrating screen, and also includes:
[0028] The cover body 2 is installed on the top of the vibration screen body 1. The cover body 2 is installed on the end of the screen 22 with a smaller aperture on the vibration screen body 1, and there is a gap between the bottom of the cover body 2 and the screen 22. A drop hopper 3 is installed on the cover body 2, and a feeding assembly 5 is connected to the drop hopper 3. The feeding assembly 5 can reduce the dust raised during the feeding process. When the plastic particles enter the cover body 2 through the drop hopper 3 and fall on the vibration screen body 1, the dust raised under the action of the vibration force is not easy to spread around the vibration screen body 1 under the action of the cover body 2;
[0029] A dust collecting box 4 is installed on the outside of the cover body 2. The dust collecting box 4 has a collecting port 6. A baffle 7 is installed on the inner wall of the cover body 2. A plurality of dust suction holes 8 are evenly distributed on the baffle 7. The collecting port 6 covers the plurality of dust suction holes 8. The baffle 7 can intercept plastic particles, making it difficult for them to enter the collecting port 6. The plurality of dust suction holes 8 can suck the raised dust into the collecting port 6, so that the dust can enter the dust collecting box 4 through the collecting port 6.
[0030] The suction piece is installed on the dust box 4 and is used to extract the air inside the dust box 4. When the air inside the dust box 4 is discharged through the suction piece, a negative pressure can be formed in the dust box 4, and the collection port 6 can suck air inwardly, and the raised dust can be sucked into the collection port 6 through the multiple dust suction holes 8;
[0031] The dust filter assembly 10 is arranged between the collecting port 6 and the air extractor, and is used to separate air from dust. When air enters the air extractor through the dust collecting box 4, the dust filter assembly 10 can intercept the dust, making it difficult to be discharged with the air, thereby not easily polluting the environment around the vibrating screen body 1;
[0032] The present application adopts the design of the cover body 2. When the plastic particles enter the cover body 2 through the drop hopper 3 and fall on the vibrating screen body 1, the dust raised under the action of the vibration force is not easy to spread toward the vibrating screen body 1 under the action of the cover body 2. Subsequently, the air inside the dust box 4 can be extracted through the suction piece to form a negative pressure inside. The collection port 6 can inhale air inwardly, and the raised dust can be sucked into the collection port 6 through multiple dust suction holes 8. When the air enters the suction piece through the dust box 4, the dust filter assembly 10 can separate the air from the dust, so that it is not easy to pollute the surrounding environment.
[0033] like Figure 3 As shown, in some embodiments, the inner wall of one side of the hopper 3 is coplanar with the baffle 7, and the inner diameter width of the hopper 3 decreases from top to bottom, and the shortest distance between the inner wall of the other side of the hopper 3 and the baffle 7 decreases from top to bottom. Such a design makes the bottom end of the hopper 3 elongated, so that the plastic particles passing through its bottom are close to the baffle 7 and in a curtain shape, so that the multiple dust suction holes 8 can absorb the dust mixed therein, and since the cover body 2 is fixedly mounted on the vibrating screen body 1, the vibration force generated during its operation can be transmitted to the hopper 3 through the cover body 2, thereby causing resonance of the plastic particles therein, making it less likely to block the bottom of the hopper 3.
[0034] like Figure 1-Figure 3 As shown, in some embodiments, the vacuum component is an air pump 9, which is installed on the vibrating screen body 1, and its air inlet end is connected to the dust box 4. When the air pump 9 is working, the gas in the dust box 4 can be extracted to form a negative pressure therein.
[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the dust filter assembly 10 includes a fixed pipe 11, a connecting port 12 is opened on the dust box 4, the end of the fixed pipe 11 covers the connecting port 12, the fixed pipe 11 is located outside the dust box 4, a dust filter bag 13 is installed in the connecting port 12, and the dust filter bag 13 is located in the fixed pipe 11, and the end of the fixed pipe 11 is connected to the air pump 9. When the air pump 9 is working, the air inside the dust box 4 can be extracted through the fixed pipe 11, and then the air entering the connecting port 12 through the dust box 4 will be separated from the dust under the action of the dust filter bag 13.
[0036] like Figure 3 and Figure 4As shown, in some embodiments, a cleaning port 14 is opened on one side of the fixed pipe 11, and an outer cover 15 for closing the cleaning port 14 is provided thereon, the outer cover 15 is hinged on the fixed pipe 11, and its movable end is connected to the fixed pipe 11 through a buckle, after the buckle is released to fix the outer cover 15, the cleaning port 14 can be opened, and an annular block 16 is installed at the feeding end of the dust filter bag 13, which is threadedly matched with the connecting port 12, and the connecting port 12 is annular. With such a design, after punching the cleaning port 14, the annular block 16 can be separated from the connecting port 12 by rotating it along the thread direction, so as to facilitate the cleaning of the dust filter bag 13.
[0037] like Figure 3 and Figure 4 As shown, in some embodiments, the connecting port 12 is arranged at the bottom of the dust collecting box 4, and the fixed pipe 11 is vertically installed on the vibrating screen body 1. Such a design allows the dust filter bag 13 to be vertically arranged in the fixed pipe 11. When it is disassembled, the dust entering from the top feed end is not easily discharged from the feed end when the annular block 16 is rotated, so that it is easy to clean.
[0038] like Figure 3 and Figure 4 As shown, in some embodiments, a support frame 17 is constructed at the bottom of the annular block 16, and the dust filter bag 13 is mounted on the outer side of the support frame 17, so that the dust filter bag 13 can be fixed, so that when air passes through, the dust filter bag is not easily deformed and contacts the inner wall of the fixed pipe 11, so that the dust filter bag 13 is not easily worn.
[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the feeding assembly 5 includes a vacuum conveyor 18 installed on the side of the vibrating screen body 1, which is a prior art. It is connected to the output end of the air pump 9, and its feeding end and discharging end are respectively equipped with a feeding pipe 19 and a discharging pipe 20. When the air pump 9 is working, the air sucked out from the dust box 4 can move quickly toward the discharge pipe 20 of the vacuum conveyor 18, thereby driving the air inside the feeding pipe 19 to move. At this time, the air pressure in the feeding pipe 19 is reduced, and the plastic particles can be sucked into its end and move toward the discharge pipe 20. A cover plate 21 is installed on the top of the drop hopper 3, and the end of the discharge pipe 20 passes through the top of the cover plate 21 and is connected to the drop hopper 3. When the plastic particles enter the vacuum conveyor 18 through the feeding pipe 19, they can enter the drop hopper 3 through the discharge pipe 20, thereby effectively avoiding the dust in the plastic particles from floating in the air during the feeding process.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
