For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] Reference Figures 1-6 According to an embodiment of the utility model, a plastic particle dust removal device with multiple dust removals includes a dust removal box 11, a working chamber 12 is provided in the dust removal box 11, a vibration tray 13 is provided in the working chamber 12, and an oscillation motor 15 is provided on the bottom surface of the vibration tray 13, a discharge chute 16 is provided in the bottom surface of the vibration tray 13, and a bottom plate 17 for closing the discharge chute 16 is provided on the lower side of the vibration tray 13, and a control mechanism for controlling the position of the bottom plate 17 is also included, and a discharge port is provided in the bottom surface of the working chamber 12.

[0032] A dust suction component No. 18 and a dust suction component No. 2 19 are provided on the curved surface of the working chamber 12. The dust suction component No. 18 and the dust suction component No. 2 19 are respectively arranged on the upper and lower sides of the vibration material plate 13, and also include a dust cleaner (not shown in the figure). The vacuum cleaner is connected to the dust suction component No. 1 18 and the dust suction component No. 2 19 through a hose.

[0033] When the discharge chute 16 is closed, if the vibration motor 15 is working, the plastic particles in the vibration tray 13 will vibrate and cause dust to be emitted. At this time, the emitted dust will be collected by the No. 1 dust collection component 18 and enter the vacuum cleaner through the No. 1 dust collection pipe 41.

[0034] After a certain period of time, when the No. 1 dust collection component 18 completes the processing, the vibration motor 15 remains in working condition, and the bottom plate 17 no longer covers the discharge trough 16. At this time, the plastic particles in the vibration tray 13 will fall through the discharge trough 16, and the dust emitted by the plastic particles in this process will be collected by the No. 2 dust collection component 19.

[0035] In this embodiment, the No. 1 dust suction component 18 includes a No. 1 dust suction pipe 41 installed on the side of the working chamber 12 , and the No. 1 dust suction pipe 41 is located on the upper side of the vibration material tray 13 .

[0036] In addition, in order to ensure that the plastic particles are in a dispersed state when passing through the discharge trough 16, the discharge trough 16 is provided with multiple and array-distributed, and the bottom plate 17 is provided with multiple connecting grooves 20 that pass through the top and bottom and are adapted to the size of the discharge trough 16. The control mechanism includes a mounting frame 21 provided on the lower side of the vibration plate 13, and the bottom plate 17 is connected to the mounting frame 21 for sliding left and right, and a spring is provided in the mounting frame 21 to press on the bottom plate 17. The side of the mounting frame 21 equipped with the spring is also provided with an electromagnet 22 that can attract the bottom plate 17 so that the discharge trough 16 is facing the connecting groove 20.

[0037] When the electromagnet 22 is in a power-off state, the connecting groove 20 is misaligned with the discharge groove 16, and the plastic particles in the vibration tray 13 will not fall down. When the electromagnet 22 is energized, the bottom plate 17 will move to the right, and the connecting groove 20 will face the discharge groove 16. At this time, under the vibration of the oscillation motor 15, the plastic particles in the vibration tray 13 can fall evenly from each of the discharge grooves 16 to improve the dust collection effect of the No. 2 dust collection component 19.

[0038] In order to further improve the dust suction effect of the No. 2 dust suction component 19, the discharge trough 16 is distributed on the front and rear sides of the vibration motor 15, and a vibration cavity 14 for accommodating plastic particles is provided in the upper side of the vibration plate 13. A trapezoidal boss 23 is provided on the bottom surface of the vibration cavity 14. The boss 23 is located on the upper side of the vibration motor 15. The boss 23 extends left and right and is connected to the left and right sides of the vibration cavity 14. When the discharge trough 16 and the connecting groove 20 are no longer misaligned, the setting of the boss 23 ensures that as few plastic particles as possible remain in the vibration cavity 14.

[0039] In this embodiment, the second dust suction assembly 19 includes three second dust suction pipes 42 extending transversely and distributed front to back. The front and rear second dust suction pipes 42 are respectively located on the front and rear sides of the discharge chute 16, and the middle second dust suction pipe 42 is located below the oscillation motor 15.

[0040] The sides of the No. 2 dust suction pipe 42 located on the front and rear sides are close to each other and are provided with multiple No. 1 dust suction ports distributed left and right. The No. 2 dust suction pipe 42 located in the middle is provided with No. 2 dust suction ports distributed left and right on the front and rear sides.

[0041] The arrangement of the plurality of No. 2 dust suction pipes 42 can absorb dust to the maximum extent.

[0042] In addition, a feeding assembly is also included, which includes a storage bin 24 and a screw conveyor 25. The inlet of the screw conveyor 25 is connected to the discharge port in the storage bin 24, and the end of the screw conveyor 25 extends into the working chamber 12.

[0043] In order to enable preliminary dust removal of the plastic particles when they are in the screw conveyor 25, the screw conveyor 25 includes a cover body 26, a screw rod and a transfer motor for driving the screw rod to rotate. The vacuum cleaner is also connected to the cover body 26 through the No. 3 dust suction pipe 43.

[0044] A dust concentration sensor 27 is provided in the working chamber 12 .

[0045] Specific plastic particle dust removal process:

[0046] The transfer motor works intermittently to enable the plastic particles in the storage bin 24 to be transferred to the vibration chamber 14. During the transfer process of the plastic particles, the third dust suction pipe 43 performs preliminary dust removal. When the transfer motor is powered off, the third dust suction pipe 43 no longer performs the suction work.

[0047] After the transfer motor is powered off, the oscillation motor 15 is powered on and the No. 1 dust suction pipe 41 starts to suck air. At this time, the plastic particles in the vibration material chamber 14 can be oscillated and secondary dust removal can be performed.

[0048] When the dust concentration sensor 27 senses that the dust concentration in the working chamber 12 reaches below the threshold, the electromagnet 22 is energized and the No. 2 dust suction pipe 42 sucks air. At this time, the plastic particles in the shock material chamber 14 can fall evenly in each of the discharge troughs 16, and in this process can be dust-removed for the third time by the No. 2 suction pipe 42.

[0049] It should be noted that the suction ports of the No. 1 dust suction pipe 41, the No. 2 dust suction pipe 42 and the No. 3 dust suction pipe are all provided with filters to avoid the inhalation of plastic particles. The vibration material plate 13 is supported for installation and can vibrate.

[0050] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
