Problems solved by technology

[0002] When the existing rotor-type powder separator selects powder, because the powder separator adopts the bottom air inlet method for powder selection, part of the air will leak from the feeding device during feeding, which affects the inside of the powder separator. The wind volume and wind pressure, and the wind will cause dust due to the reverse discharge

Embodiment Construction

[0008] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] Such as figure 1 As shown, the blanking air locking device of the rotor type powder separator includes: a blanking cylinder 2 arranged on the frame 1, and a rotating shaft 4 is provided through a bearing 3 in the discharging cylinder 2, and the rotating shaft 4 is connected to the The windshield valve plate 5 is connected.

[0010] When unloading, the windshield valve plate 5 and the rotating shaft 4 rotate together. When the material is not unloaded, the windshield valve plate 5 naturally sags due to gravity and contacts the blanking cylinder 2 to form a seal. When unloading, the windshield valve plate 5 receives the material The powder is extruded and opened automatically according to the thickness of the material layer, so as to achieve the purpose of simultaneous feeding and air lock, which effectively redu...

Abstract

The invention discloses a blanking air locking device for a rotor powder selecting machine. The device can reduce air volume loss and dust rising in the powder selecting machine. The device comprises a blanking barrel arranged on a machine frame, a rotary shaft is arranged in the blanking barrel through a bearing, and the rotary shaft is connected with a wind blocking valve plate. The blanking air locking device has the advantages of being simple in structure and convenient to use, enabling blanking and air locking to be conducted simultaneously and being capable of reducing air volume loss and dust rising in the powder selecting machine.

Description

technical field [0001] The invention relates to a rotor-type powder separator, in particular to a material-feeding and air-locking device of the rotor-type powder separator. Background technique [0002] When the existing rotor-type powder separator selects powder, because the powder separator adopts the bottom air inlet method for powder selection, part of the air will leak from the feeding device during feeding, which affects the inside of the powder separator. The wind volume and wind pressure, and the wind will cause dust due to the reverse discharge. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a material-feeding and air-locking device of a rotor-type powder separator that can reduce the air volume loss and dust raising inside the powder separator. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: the blanking and air lock devic...
