Novel double-layer air locking material feeder

Abstract

The invention discloses a novel double-layer air locking material feeder, which comprises an upper layer machine body and a lower layer machine body of the material feeder, wherein the upper layer machine body is connected with the lower layer machine body through a flange; valve shafts are respectively arranged in the upper layer machine body and the lower layer machine body; valve plates are respectively connected to the upper and lower layer machine bodies through the valve shafts; the outer end of each valve shaft is connected with a balance weight; magnetic blocks are respectively arranged at the lower ends of the upper and lower layer machine bodies and the lower end of the flange; each valve plate is connected with an extending valve plate through a hinge; magnetic blocks with the polarities opposite to those of the previous magnetic blocks are arranged on the lower sides of the extending valve plates; and magnetic blocks with the polarities which are the same as those of the previous magnetic blocks are arranged on the lower sides of the valve plates. The extending valve plates are arranged on the valve plates through the hinges; when a small number of materials are required to be fed, even if the valve plates are going to be closed by the balance weights, the valve plates are not closed as the polarities of the valve plates are the same as those on the flange and the machine bodies, so that the materials can completely fall off; the magnets with the polarities which are opposite to the polarities on the flange and the machine bodies are arranged on the extending valve plates, so that the materials can be completely discharged; and the opposite polarities attract each other, so that the valve plates can be closed tightly, and wild wind can be prevented from being blown in.

Description

technical field [0001] The invention relates to a feeding machine, in particular to a novel double-layer wind-locking feeding machine. Background technique [0002] The feeder, also known as the flap valve, has been widely used as a feeding device in the electric power, metallurgy, coal, chemical and other industries, but the existing feeder generally realizes the opening or closing of the valve plate through the counterweight , when the material in the valve plate reaches a certain amount, the valve plate will open and the material will fall, but when the material is less, the valve plate is easy to close automatically, so that the material cannot fall completely. Contents of the invention [0003] In order to solve the above problems, the present invention provides a double-layer airlock feeder that can make feeding and unloading clean and has good sealing performance. [0004] In order to achieve the above object, the present invention is achieved through t...
