Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screen equipment, in particular to an anti-material accumulation ultrasonic vibrating screen. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] In powder metallurgy processes, some ultrafine powders or those with large surface areas tend to agglomerate into balls during packaging and transportation. These small balls are difficult to disperse after mixing with other powders, seriously affecting the uniformity of the mixing process. Therefore, powders are generally screened before mixing. For some severely agglomerated particles, ultrasonic vibration and other methods are required to force screening. Although ultrasonic vibrating screens improve work efficiency compared to other screening methods, the addition of ultrasonic vibration devices makes it difficult to clean the residual tailings on the screen and at the bottom of the ultrasonic vibrating screen, often requiring the screen to be removed for cleaning, which is cumbersome.

[0022] The following is combined with Figure 1 , describing the specific implementation of this embodiment.
[0023] The present application provides an ultrasonic vibrating screen for preventing material accumulation, referring to Figure 1An ultrasonic vibrating screen for preventing material accumulation includes a base 13, a screening box located above the base 13, a screen 16 located within the screening box, and a vibration motor 15 fixed to the bottom of the screening box. The vibration motor 15 drives the screening box to vibrate, and combined with ultrasonic vibration, it further enhances the screening effect of the screen 16. Furthermore, to prevent the screening box from damaging the base 13 during operation of the vibration motor 15, the base 13 and the screening box are connected by a spring 14, which provides a good buffering and shock-absorbing effect during operation.
[0024] The two sides of the screen 16 are fixed to the inner wall of the screening box, and the screening box is divided into an upper screening cavity and a lower screening cavity by the screen 16. A feeding port 8 is provided on the top of the upper screening box, and the powder to be screened is added into the screening box through the feeding port 8. A dust cover 11 is also provided on the feeding port 8. During operation, the dust cover 11 can effectively prevent the powder from diffusing to the outside, and can also prevent the influence of external dust on the powder.
[0025] A barrier 4 is installed between the screen 16 and the inner wall of the screening box. The barrier 4 can effectively prevent powder from accumulating in the gap between the screen 16 and the screening box, thereby reducing powder waste and making cleaning easier. A transducer 9 is also installed below the screen 16. The transducer 9 is connected to an external ultrasonic resonant power supply 10. The transducer 9 converts the sound wave energy emitted by the ultrasonic resonant power supply 10 into mechanical energy, causing the screen 16 to vibrate at a high frequency, thereby sieving the powder.
[0026] In order to further optimize the screening process and prevent the ultrasonic vibration device from failing to separate the severely agglomerated powder, a material brush 1 is provided on both sides above the screen 16. The forced stirring by the material brush 1 can crush and sieve a large volume of severely agglomerated powder, thereby ensuring that the ultrasonic vibration screen achieves the best effect in screening the powder. The material brush 1 is fixed by two butterfly bolts 2, which pass through the screening box. Two nuts 3 are also installed on the butterfly bolts 2. The two nuts 3 are respectively located on the inside and outside of the screening box to achieve the fixation of the butterfly bolts 2 and the screening box. Since the material brush 1 is fixed by two butterfly bolts 2, the fit between the material brush 1 and the screen 16 can be controlled by adjusting the butterfly bolts 2, so as to better crush the agglomerated powder. For example, when the volume of the agglomerated powder is small, the distance between the material brush 1 and the screen 16 can be reduced by tightening the butterfly bolts 2, ensuring that the material brush can better crush the agglomerated powder.
[0027] A first blowing port 6 is provided above the feeding port 8 of the upper screening chamber. The size of the first blowing port 6 matches that of the feeding port 8. During use, it is only necessary to remove the dust cover 11 and then connect the first blowing port 6 to the feeding port 8. A discharge port 12 is provided on the inner wall of one side of the lower screening chamber, and a second blowing port 7 is provided on the inner wall of the other side. The first blowing port 6 and the second blowing port 7 are connected to the external air compressor 5 through a ventilation duct. The air compressor 5 supplies air. The first blowing port 6 can be used to blow out the powder on the screen 16, and the second blowing port 7 can be used to blow out the powder at the bottom of the lower screening chamber from the discharge port 12. Therefore, the screening work can be carried out without manually disassembling the screen 16, which can effectively save labor and improve work efficiency. Experimental verification shows that through the cooperation of the brush and the blowing port, the residual powder inside the ultrasonic vibrating screen is reduced from 30-60g to less than 1g, effectively solving the problem of residual tailings inside the ultrasonic vibrating screen being difficult to clean.
[0028] The working principle of the anti-accumulation material ultrasonic vibrating screen in this embodiment is as follows:
[0029] Turn on the ultrasonic resonant power supply 10, adjust the distance between the material brush 1 and the screen 16 through the butterfly bolt 2, add the powder into the screening box through the feeding port 8, and through the cooperation of the material brush 1 and the screen 16 that performs ultrasonic vibration, it is possible to crush the larger agglomerated powder and force it to be screened. The enclosure 4 is used to prevent the powder from accumulating in the gap between the screen 16 and the screening box during the screening process, which can reduce the waste of raw materials and effectively reduce the difficulty of cleaning. Finally, air is pumped in through the air compressor 5, and the remaining powder located at the bottom of the screen 16 and the screening box is blown out from the discharge port 12 through the first blowing port 6 and the second blowing port 7. No manual disassembly of the screen 16 is required, and the ultrasonic vibration screen can be quickly cleaned.
[0030] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
