DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-6 The utility model provides a technical solution: a silicon carbide particle screening device, including: a screening bin 1, a bin 2, a feed port 3, a discharge port 4, an opening and closing baffle 5, a connecting rod 6, a connecting rod member 7, a turntable 8, a first guide rod 9, a hinged rod 10, a motor 11, a rotating rod 12, a second guide rod 13, a screening plate 14, a first synchronous pulley 15, a synchronous belt 16, a synchronous motor 17, and a second synchronous pulley 18.
[0028] First, as attached Figure 1 , Attachment Figure 3 and attached Figure 5 As shown in , when the screening equipment is used to screen silicon carbide, silicon carbide is first poured into the interior of the silo 2. First, since the opening and closing baffle 5 is set in a closed state, the motor 11 is started, so that the output end of the motor 11 drives the turntable 8 to rotate inside the silo 2, and the turntable 8 drives the first guide rod 9 to rotate. Since the upper end of the hinged rod 10 is connected together by the connecting rod and the lower end of the connecting rod 7, the connecting rod 7 is set in an "L"-shaped structure, so that the first guide rod 9 drives the connecting rod 7 to flip through the hinged rod 10, and at the same time, the connecting rod 6 is set in an inclined state, so that the connecting rod 6 drives the connecting rod 6 to rotate synchronously, so that the connecting rod 7 and the connecting rod 6 drive the opening and closing baffle 5 to open and close, and then the opening and closing baffle 5 slides on the side wall of the silo 2, so that the speed of silicon carbide feeding is adjusted according to the opening and closing width of the opening and closing baffle 5, so as to achieve quantitative feeding of silicon carbide;
[0029] As attached Figure 1 and attached Figure 6 As shown in, after adjusting the feeding speed of silicon carbide, it is then connected with the feed port 3 through the silo 2, so that the silicon carbide inside the silo 2 flows into the feed port 3. Since the inside of the feed port 3 is arranged in an inclined state, and at the same time, the lower end of the feed port 3 is arranged in a corresponding state with the left screen plate 14 in the screening bin 1 and the right screen plate 14 in the screening bin 1, the silicon carbide inside the silo 2 flows into the surfaces of the screen plates 14 at the left and right ends of the screening bin 1 through the feed port 3, so that the load of the screening equipment can be reduced by diversion, and the screening efficiency can be increased by two groups of screen plates 14;
[0030] As attached Figure 1 , Attachment Figure 2 and attached Figure 4As shown in, after silicon carbide flows into the surface of the screening plate 14, the synchronous motors 17 at the left and right ends of the front end of the screening bin 1 are started. Since the second synchronous pulley 18 on the output end of the synchronous motor 17 is sleeved and connected with the first synchronous pulley 15 on the rod body of the rotating rod 12 through the synchronous belt 16, the upper first synchronous pulley 15 in the screening bin 1 and the lower first synchronous pulley 15 in the screening bin 1 are also sleeved and connected through the synchronous belt 16, so that the rotating rod 12 in the screening bin 1 rotates synchronously. Since the front and rear ends of the rod body of the rotating rod 12 are arranged in a "concave" shape, Thereby, the rotating rod 12 drives the screen plate 14 to rise and fall through the second guide rod 13, so that the smaller silicon carbide on the surface of the upper screen plate 14 in the screening bin 1 falls into the surface of the lower screen plate 14 in the screening bin 1, and at the same time, the rear end of the screen plate 14 is arranged in a corresponding state with the discharge plate fixed at the rear end of the screening bin 1, and the silicon carbide remaining on the surface of the screen plate 14 is discharged through the vibration of the rising and falling screen plate 14, and at the same time, the lower screen plate 14 in the screening bin 1 is arranged in a corresponding state with the discharge port 4, so that the smaller silicon carbide on the surface of the lower screen plate 14 in the screening bin 1 is discharged through the discharge port 4.
