Abstract
An air distributor head mounted in a sloping wall for a hopper for pulverulent material to agitate and aerate the material as it travels down the wall surface toward the discharge opening in the bottom of the hopper; the head assembly including a generally cylindrical head with air flow passages and having an expandable generally cylindrical resilient skirt surrounding the body thus permitting air supplied through the passages under the skirt to be discharged into the pulverulent material to incorporate a flow of agitating and fluidizing air into the material.
Claims9
Apparatus for agitating and aerating finely divided material in a hopper, said apparatus comprising:
- a hollow generally cylindrical air distributor body having upper and lower portions and defining a chamber therewithin with air flow passages formed there-through,
- a resiliently yieldable skirt member mounted around the outer side wall of said cylindrical distributor body to form a head assembly and being anchored at the upper portion of said body with the lower circumferential portion of said skirt being free to expand under the pressure of air discharged through the air flow openings,
- means for supplying air under pressure into the chamber within said body, and
- means for mounting the head assembly within a lower portion of a hopper unit to permit the air discharged around the lower circumferential portion of the resilient skirt portion to flow into finally divided material contained in the hopper to assist in discharging said material through an opening in the bottom of the hopper.
An air distributor system for discharging air into a hopper at a plurality of selected locations for aerating and agitating finely divided material in the hopper, said assembly comprising,
- a plurality of hollow head assemblies,
- a hollow stem fixed to each head assembly and extending downwardly therefrom, and defining an airflow passage therethrough,
- said hollow stem having openings therein communicating with said passage,
- a supply connector for each head assembly having a hollow central chamber receiving said stem with means for securely clamping the upper edge of the connector and the lower edge of the head on opposite sides of the hopper to be aerated,
- a restricting ring formed on said connector and extending down into said chamber in closely spaced relation to the openings in said stem to controllably restrict the air flow from the central chamber through said openings into the airflow passage, and
- said connector having a plurality of discharge passages communicated with said central chamber to distribute the air supplied to said chamber to other distributor head assemblies.
