초록 ▼

This application discloses several components relating to a heating apparatus which preferably are used in conjunction with each other in an apparatus for heating solid granular or particulate material, such as aggregate used to make asphalt concrete. One component of the present invention includes a heater-condenser unit which indirectly heats the material by circulating heat transfer fluid within hollow plates contained in a housing holding the material. The material is heated, the heat transfer fluid is condensed and a condensate removal means associated with the hollow plates removes the condensate from the housing. The heat transfer fluid used in the heater-condenser preferably is supplied in the form of a vapor or gas evolved from liquid contained in material heated by another type of heater. In this other type of heater, the material to be dried enters a chamber containing hollow heat exchange plates through which a primary heat transfer fluid is circulating. The material is heated to a temperature at which the liquid is evaporated and the evolved vapor is collected within the heater, routed through an accumulating apparatus and transferred out of the heater to the heater-condenser. Other components associated with the present invention include a material flow control apparatus to be attached to the bottom of a bottom discharging solid material containing hopper. The flow control apparatus includes a plurality of bars adjustably extending into the hopper.

대표청구항 ▼

Apparatus for indirectly heating aggregate material containing at least some liquid comprising a preheater-condenser for preheating the material, a heater for heating the preheated material and for generating a vaporous heater generated heat transfer fluid from the material, first conduit means connecting the preheater-condenser to the heater through which the heater generated heat transfer fluid is carried from the heater to the preheater-condenser, and conveyor means for conveying preheated material from the preheater-condenser to the heater, the preheater-condenser including a housing, inlet means through which the material enters the housing, outlet means for discharging the preheated material from the housing, first hollow heat exchange means supported vertically within the housing, first distributing means connecting the first conduit means and the first hollow heat exchange means for distributing the heater generated heat transfer fluid to the first hollow heat exchange means, and condensate removal means connected to the first hollow heat exchange means for removing from the housing condensed heater generated heat transfer fluid from the first hollow heat exchange means, the heater including a receptacle and a chamber in which the material is heated, a sealable inlet means through which the preheated material to be heated enters the receptacle, but through which gases formed in the heater will not escape to the atmosphere, the chamber having outlet means through which heated material is discharged from the chamber, heating means supported in a vertical orientation within the chamber, a plurality of collecting means supported within the chamber for collecting the heater generated heat transfer fluid from the material being heated, and accumulating means for accumulating the heater generated heat transfer fluid from the plurality of collecting means, the accumulating means being in communication with the collecting means and with the first conduit means through which the heater generated heat transfer fluid flows to the preheater-condenser.
