[0002] Silicon carbide has the characteristics of stable chemical properties, high thermal conductivity, low thermal expansion coefficient, high hardness, strong wear resistance and self-sharpening, etc. It is widely used in industries such as processing cemented carbide and optical glass. Its quality is not only related to its purity, but also to its particle fineness. The higher the purity and the finer the particles, the higher the application quality and the wider the application range. Therefore, a drum sand screen is needed to screen out the finer particles of silicon carbide.
[0003] The screen drum of the existing drum-type sand screening machine is usually set at a fixed angle, but the screen drum set at a fixed angle is prone to the possibility that some materials are not screened in time and are carried out by the rotating screen drum. In order to solve this problem, the drum of such equipment needs to be set longer to fully screen the material, which leads to excessive space occupation of the equipment and increases the subsequent maintenance work of the drum. Therefore, based on the above problem, a drum-type silicon carbide sand screening machine with adjustable angle is proposed. Utility Model Content

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction.

It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

The outer end surface of the track ring 7 fits with the inner wall of the track groove 5. The diameter of the rotating drum 6 is the same as the inner diameter of the cover shell 3. The rotating member 2 is arranged so that the cover shell 3, the rotating drum 6 and the screen plate 8 can be adjusted to a certain angle. The rotating drum 6 can be limited by the set track ring 7 and the track groove 5, so that the rotating drum 6 can only rotate; the shaft rod 10 is arranged on the inner side of the rotating drum 6, and the center of the shaft rod 10 and the center of the rotating drum 6 are arranged on the same axis. The length of the shaft rod 10 is 1.3 times the length of the rotating drum 6. The limiting plate 11 is arranged on the outer side of the rotating drum 6. The shaft rod 10 and the fixing frame 12 can drive the rotating drum 6 to rotate on the same axis. The length of the shaft rod 10 allows the lifting plate 14 and the ball 15 to lift the right end of the shaft rod 10; the lifting plate 14 is arranged on the lower side of the shaft rod 10, and the lifting plate 14 and the ball 15 are There is a spacing between the shafts 10, and the balls 15 are arranged on both sides of the shafts 10. The surfaces of the balls 15 are in contact with the outer curved surfaces of the shafts 10. The limit plate 11 is arranged on the right side of the lifting plate 14.

[0028] Working process: when it is necessary to use the drum sand screening machine to screen silicon carbide, the motor 9 is started by the controller to make the output shaft end of the motor 9 drive the shaft rod 10 and the fixed frame 12 to rotate, and the rotation of the fixed frame 12 drives the rotating drum 6 and the sieve plate 8 to rotate. At the same time, the cylinder 13 is started to lift by the controller, and the lifting of the cylinder 13 drives the lifting plate 14 and the ball 15 to move upward. The upward displacement of the ball 15 will push the right end of the shaft rod 10 to move upward. The upward movement of the right end of the shaft rod 10 will cause the rotating part 2, the cover 3, the rotating drum 6 and the sieve plate 8 to rotate, so that the right ends of the rotating drum 6 and the sieve plate 8 are lifted upward. After the angle adjustment of the drum 6 and the sieve plate 8 is completed, silicon carbide is transported into the cover 3, the drum 6 and the sieve plate 8 through the hopper 4. The rotation of the drum 6 and the sieve plate 8 will screen the silicon carbide, and the lifting of the right ends of the drum 6 and the sieve plate 8 can prevent the silicon carbide from being rotated out. After sufficient screening, the cylinder 13 is contracted through the controller, and the downward movement of the lifting plate 14 and the ball 15 will cause the right end of the shaft 10 to move downward, and then cause the right end outlet of the drum 6 to move downward. At this time, the material can flow out through the right end outlet. Through the above operation, the drum sand screening machine can fully screen the silicon carbide by adjusting the angle of the sieve drum.
