Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figures 1 and 2, the sieving and iron removing device for the zirconia granulated powder comprises a sieving bin 1. The screening bin 1 is a square bin made of silicon rubber or fluororubber and is arranged on a screening bin supporting frame 19. The top of the sieving bin is provided with a feeding hole 11, and the bottom of the sieving bin is provided with a discharging hole 1. Wherein, the discharge port 12 adopts a funnel mouth structure. The feed inlet 11 adopts an inverted funnel mouth structure. A horizontal screen 2 is arranged inside the screening chamber 1. The screen 2 is a 400-1000 mesh filter screen and is a stainless steel screen. The edge of the screen 2 is fixed with the wall of the screening bin 1. A plurality of screen support rods 21 are provided below the screen 2 and supported by the screen support rods 21. The screen support rods 21 are arranged horizontally and parallel to each other and at equal intervals on the wall of the screening chamber 1. Two ends of the screen support rod 21 penetrate through the wall of the sieving bin 1 and extend out of the sieving bin 1, and two ends of the screen support rod 21 are respectively connected with an ultrasonic vibrator 22 outside the sieving bin 1. I.e. the ultrasonic vibrator 22 is located outside the screening silo 1. In the present embodiment, the screen support rods 21 are square long rods made of stainless steel, and those skilled in the art will understand that the screen support rods 21 may also be round long rods.
The screen 2 will sieve storehouse 1 and cut apart into two upper and lower cavitys: a pre-screen chamber 13 and a ferromagnetic chamber 14. Wherein, the screen fore cavity 13 is positioned above the screen 2, and the strong magnetic cavity 14 is positioned below the screen 2. A plurality of strong magnetic rods 3 are densely distributed in the strong magnetic cavity 14. The strong magnetic bar 3 is horizontally arranged, and two ends of the strong magnetic bar are respectively connected with the bin wall of the sieving bin 1. The strong magnetic rods 3 are divided into a plurality of layers, and each layer of strong magnetic rods 3 comprises a plurality of strong magnetic rods 3. Each layer of strong magnetic rods 3 is at the same height, that is, each layer of strong magnetic rods 3 is arranged on the same horizontal plane. And each layer of the strong magnetic rods 3 are parallel to each other and arranged at equal intervals. The strong magnetic rods 3 between layers are arranged in a staggered mode, and in each layer of strong magnetic rods 3, the gap between the strong magnetic rods 3 does not exceed the diameter of the strong magnetic rods 3. From this, the zirconia powder body through screen cloth 2 can't directly fall into discharge gate 12 through the action of gravity, and must need through strong bar magnet 3, after the slip on strong bar magnet 3, just can fall into discharge gate 12.
Further, the outer layer of the strong magnetic rod 3 is coated with a low-friction-coefficient material layer, and the low-friction-coefficient material layer is preferably made of silica gel or polytetrafluoroethylene. More specifically, the ferromagnetic rod 3 of this embodiment is formed by splicing a plurality of cylindrical neodymium iron boron ferromagnetic bodies with a diameter of 20mm and a length of 100mm, and then coating the ferromagnetic bodies with outer silica gel or polytetrafluoroethylene by a thermoplastic process.
Further, a finished product barrel 4 is arranged below the discharge port 12.
The working principle of the embodiment is as follows: when the zirconia granulated powder is sieved, the ultrasonic vibrator 22 is started. The ultrasonic vibrator 22 generates ultrasonic vibration, which is transmitted to the screen 2 through the screen support rod 21 to drive the screen 2 to vibrate ultrasonically, so that the small-sized powder above the screen 2 passes through the meshes of the pair of screens 2 under the ultrasonic vibration and then falls into the strong magnetic cavity 14, and the large-sized particles are left on the screen 2. The powder entering the strong magnetic cavity 14 finally falls on the strong magnetic rod 3 and slides along the two sides of the strong magnetic rod 3, and at the moment, the iron in the powder is adsorbed on the strong magnetic rod 3.
