[0036] Refer to the following Figure 1 to Figure 2 The technical solutions of some embodiments of the utility model are described.

[0037] See attached Figure 1 As shown, the utility model provides a negative pressure vibrating screen 100 screening and impurity removal device, comprising:

[0038] At least one vibrating screen 100, the vibrating screen 100 comprises a feed inlet 110, a screen 120 and an ultrasonic vibrator 130, the feed inlet 110 is arranged above the vibrating screen 100, the material enters the vibrating screen 100 through the feed inlet 110, the ultrasonic vibrator 130 is installed on one side of the vibrating screen 100, and the ultrasonic vibrator 130 is used to diffuse the slag that cannot pass through the screen 120 to the edge of the screen 120;

[0039] The slag discharge assembly includes a suction port 210 and a vacuum generating assembly 220. The suction port 210 is arranged above the edge of the screen 120. The vacuum generating assembly 220 is connected to the vibrating screen 100, so that the vibrating screen 100 is in a negative pressure state, thereby discharging the slag on the edge of the screen 120 through the suction port 210.

A feed port 110 is provided on the top of the vibrating screen 100, and the material enters the vibrating screen 100 from the feed port 110. The ultrasonic vibrator 130 is turned on, and the material on the surface of the screen 120 forms a certain air-to-material ratio with the air due to the vibration force of the ultrasonic vibrator 130, so that the material has better permeability. The material that can pass through the screen 120 falls from the screen 120, and the slag that cannot pass through remains on the screen 120, thereby completing the material impurity removal process, so that the separation effect is good, the slag residue is less, and the finished product collection rate is improved. The slag on the screen 120 is diffused to the edge of the screen 120 by the vibration action of the ultrasonic vibrator 130.

The vacuum generating assembly 220 is turned on to form a negative pressure at the position of the suction port 210, so that the airflow carries the slag at the edge of the screen 120 into the suction port 210, thereby discharging the slag. The negative pressure makes the slag discharge smoother, thereby improving the slag discharge efficiency.

[0042] See attached Figure 1 As shown, in an optional embodiment, the slag discharge assembly includes a waste conveying pipeline 230 and a vacuum loader 240 , and the vacuum loader 240 is connected to the suction port 210 through the waste conveying pipeline 230 , so that the slag can be discharged to the vacuum loader 240 .

When the switch valve 231 is opened, the connection between the vacuum generating assembly 220 and the vibrating screen 100 can be ensured, thereby ensuring that the vibrating screen 100 is in a negative pressure state. However, after the slag is completely discharged, the switch valve 231, the ultrasonic vibrator 130 and the vacuum generating assembly 220 are closed to complete the screening and impurity removal of the material.

[0046] In an optional embodiment, the slag removal assembly further includes a waste receiving bin 250 , which is connected to the bottom of the vacuum loader 240 , so that the slag is finally collected in the waste receiving bin 250 .

[0051] Specifically, the breathing port 140 is arranged on the side wall of the vibrating screen 100, and the breathing port 140 is arranged opposite to the suction port 210. Optionally, the breathing port 140 is arranged as a circular wire port. The setting of the breathing port 140 can make the internal environment of the vibrating screen 100 contact with the external air, thereby preventing the internal environment of the vibrating screen 100 from being deformed due to excessive negative pressure. At the same time, a filter element 141 made of PA material is provided in the breathing port 140. The setting of the filter element 141 can ensure that the vibrating screen 100 contacts with the external air without introducing other foreign matter, thereby avoiding affecting the material.

Specifically, the air extraction volume and vacuum degree can be configured according to the actual installation position of the equipment. Specifically, turning on the vacuum generator and / or the vacuum pump group and opening the switch valve 231 can form a negative pressure at the suction port 210, so that the airflow carries the slag material and is discharged through the suction port 210.
