Improvement of the vibrating screen structure of the micro-powder machine
The two repetitive vibrating micropowder sieve symmetrically rotates a plurality of cams installed in the screening cavity, the lower end of the screening box is installed with two vibrating rollers symmetrically rotating, and the plurality of cams are respectively pressed against the two vibrating rollers; the same cam and The contact of the vibrating roller causes the vibrating roller to move up and down in close contact with the cam under the gravity of the screening box under the action of the gravity of the screening box, which makes the screening box vibrate up and down to filter out impurities.
The feeding vibrating screening machine of the silicon powder grinder includes a body, a screening cavity is opened in the body, a screening box is slidably installed in the screening cavity, and a discharge is fixedly inserted at the lower end of the screening box The lower end of the discharging tube is slidably inserted into the inner bottom wall of the screening chamber and extends to the bottom of the machine body, the discharging tube is sleeved with a main vibration spring, and the screening chamber is rotatably installed In the vibrating mechanism, a feed diffusion cover is fixedly inserted into the upper top wall of the screening cavity.
The structure of the vibrating screen of the micro powder machine is improved. Two repeated vibrating micro powder screens Two repeated vibrating micro powder screens. Each of the spring grooves is equipped with an auxiliary vibration spring, and the upper end of the auxiliary vibration spring is fixed at the lower end of the screening box; the main vibration spring is in the screen When the box is vibrating, the vibration roller of the screening box is prevented from leaving the cam to maintain the stability of the vibration.
Preferably, the upper end cover of the screening box is provided with an arc-shaped screen, and the side wall of the machine body is fixedly inserted with a trash discharging groove plate. When the screen box vibrates, the sand and gravel and other impurities that roll off the curved screen will be squeezed into the trash channel plate during the upward movement of the screen box to avoid One-time discharge causes part of the raw materials to be discharged. Preferably, the upper and lower ends of the main vibration spring are respectively fixed on the lower end of the screening box and the inner bottom wall of the screening chamber;
The structure of the vibrating screen of the micro powder machine is improved. Two repeated vibrating micro powder sieve Two repeated vibrating micro powder sieve There is a shunt grid fixedly installed in the feed diffusion cover, and the shunt grid can disperse the raw materials on the curved screen when the raw materials are poured, increasing the arc The speed of vibrating sieving with a shaped screen. The symmetrically distributed multiple auxiliary vibration springs can ensure uniform vibration of the screen box when the screen box vibrates up and down, reduce the friction between the screen box and the inner wall of the screening chamber, increase the service life of the device and reduce the operating noise of the device.
