Abstract: A dust collector cup working in the principle of fall centrifugal separation, consists of cup body (13), outlet (3) on the cup body (13), inlet (1) tangential to the circumferential wall of the cup body (13), and a separator settled in the cup body (13). The separator is composed of outlet tube (9), inlet (6) on the wall of the outlet tube (9), and the isolating shield (7) under the inlet (6) of the outlet tube (9), with the outlet tube (9) linked to the outlet (3) of the cup body (13). The fall between the horizontal positions of the lower end of inlet of the cup body (13) and the upper end of the inlet (6) of the outlet tube (9) is 0-140 mm.

Abstract: A secondary cyclone separation dust cup for dust collectors includes a separator. An inner barrel body is coaxially disposed in an outer barrel body of the separator. An air inlet for inner barrel body is formed in an upper portion of the inner barrel body above air inlets for separator, tangent to a peripheral wall of the inner barrel body. A top of the inner barrel body is connected with a connecting support and a lower portion thereof passes through an isolation cover. An air inlet for dust cup is connected with an air outlet for dust cup through the air inlets for separator and the air inlet for inner barrel body. A conical barrel body with a large upper portion and a small lower portion is disposed on an inner wall of the inner barrel body, and an isolation bag is mounted below a bottom of the conical barrel body.
