Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon nitride powder screening technology, and in particular to a silicon nitride powder screening machine. Background Technology
[0002] Silicon nitride is a compound composed of nitrogen and silicon. It is a very hard ceramic material with excellent properties under high temperature, high pressure, and corrosive environments. Silicon nitride powder is commonly used to manufacture high-performance ceramic products. When sieving silicon nitride powder, it is poured into a sieving machine, and the sieve separates the powder. However, this sieving method can cause the desired particle size of silicon nitride powder to mix with smaller particles.
[0003] Chinese patent discloses a silicon nitride powder screening machine (authorization announcement number CN221453345U). The main features of this patented technology include a screening box, a motor fixedly installed on the front side of the screening box, a transmission mechanism at the output end of the motor, a back plate and a controller above the motor, a handle fixedly installed at the front end of the back plate, the controller installed on the front side of the screening box, grooves around the inner wall of the screening box, a filter screen mechanism slidably installed inside the grooves, a conveying pipe connected to the upper end of the screening box, and a discharge pipe connected to the bottom side of the screening box.
[0004] However, this patent still has shortcomings. When sieving silicon nitride powder, the powder is poured into a sieving machine, and the sieve separates the powder. However, this sieving method results in a mixture of silicon nitride powder of the desired particle size and smaller particle sizes. Therefore, those skilled in the art have provided a silicon nitride powder sieving machine to solve the problems mentioned in the background section. Utility Model Content

[0026] 2. Beneficial effects
[0027] Compared with existing technologies, the advantages of this utility model are:
[0028] This utility model adds a holding component to the support component. When it is necessary to screen silicon nitride powder, the silicon nitride powder is poured into the holding hole, and then the threaded cap is inserted into the threaded groove and threadedly connected, which facilitates the vibration screening of silicon nitride powder and prevents the silicon nitride powder from scattering due to vibration.
[0029] Meanwhile, a screening component is added to the vibration assembly.

The spring deforms elastically, and disc one and disc two can vibrate as needed. At the same time, screen one and screen two can vibrate as needed. Screen two can screen out silicon nitride powder with excessively large particle size, so that silicon nitride powder of the required particle size and silicon nitride powder of smaller particle size fall onto screen one for screening. The smaller silicon nitride powder is screened and falls, which can accurately screen out silicon nitride powder of the required particle size.
[0030] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0048] Three pillars 110 arranged in a circular array are fixed to the lower surface of the chassis 120;
[0049] A control switch box 220 is fixed to the front end of the container 210. The control switch box 220 has a display screen and buttons installed sequentially from top to bottom at the front end.

[0052] Please see Figures 4-6 As shown, and;
[0053] Vibration component 300 is disposed within holding component 200;
[0054] The vibration assembly 300 includes a fixed plate 310 fixed to the inner wall of the holding hole 222, a spring 320 fixed to the upper surface of the fixed plate 310, a disc 330 fixed to the top of the spring 320, a vibrator 360 fixed to the lower surface of the disc 330, a threaded disc 340 threadedly connected to the disc 330, a mounting hole 341 opened on the upper surface of the threaded disc 340, and a screen 350 fixed to the inner wall of the mounting hole 341.
