Principle of dust removal: the mixed air flow with dust enters the cyclone space in the cylinder 404 through the air suction pipe 7 and forms rotary air flow, coarse dust is thrown to the periphery and naturally falls under the action of centrifugal force, and finally enters the dust collecting pot 407; at the same time, fine dust which is not captured and separated by centrifugal force rises to the filter bag 411 along with the rising air flow in the middle, and the mixed gas is filtered by the filter bag 411 to form clean air and enters the filtering space 409, and the clean air in the filtering space 409 enters the exhaust fan 5 through the exhaust fan 8. The dust on the dust collecting pot and the filter bag 411 need to be cleaned regularly, and the dust collecting pot is convenient to take down and clean as the dust collecting pot is connected with the cylinder 404 through the quick connector; because the filter bag 411 is connected with the output shaft of the air cylinder, the action of the air cylinder can pull the filter bag 411, and the filter bag 411 is pulled for a plurality of times to simulate the vibration action, so that dust accumulated on the filter bag 411 is vibrated and falls into a dust collecting pot, and the filter bag 411 can be conveniently replaced after the top cover 402 is taken down.
According to the invention, different numbers of cyclone blanking drums 2 and material mixing forming machines 1 can be arranged according to products, for example, two cyclone blanking drums 2 can be arranged in the embodiment, one flexible material sucking pipe 6 is arranged on one cyclone blanking drum 2, and the two cyclone blanking drums 2 are provided with two flexible material sucking drums; the cyclone blanking drums 2 correspond to one cyclone dust collector 4, and the air suction pipes 7 of the cyclone blanking drums 2 enter the cyclone dust collector 4 through a distributing valve.
The working method of the invention comprises the following steps:
(1) The cyclone dust collector pumps the cyclone blanking cylinder into negative pressure through an exhaust pipe;
(2) The cyclone blanking cylinder absorbs pearl powder circles from the mixing and forming machine through a flexible material absorbing pipe;
(3) The pearl powder circle enters a cyclone blanking cylinder and then rotates along the inner wall of the cyclone cylinder under the action of the cyclone;
(4) The pearl powder circle slowly falls in a spiral shape under the action of gravity, and the pearl powder circle falls into the vibration screening machine below in an acceleration way due to the reduction of air pressure in the buffer cylinder;
(5) Dust generated in the wind blanking cylinder enters the cyclone dust collector through the exhaust pipe for collection.
The cyclone blanking cylinder 2 designed by the invention can cut in and rotate the entering pearl powder circle along the inner wall, so as to prevent the pearl powder circle from directly striking the inner wall, thereby ensuring the integrity of the pearl powder circle to the maximum extent; the pearl powder circle enters the buffer cylinder 22 in the rotating process, and the diameter of the buffer cylinder 22 is suddenly increased, so that the internal air pressure is reduced, the falling speed of the pearl powder circle is accelerated, and the production efficiency is improved.
