Description
Technical Field
The utility model relates to a flash roaster furnace is used in laboratory belongs to roasting equipment technical field.
Background
Flash roasting is applied to the production of roasted cement, phosphate, bauxite and limestone in the mineral industry, and has the advantages of energy conservation, high efficiency and the like. Meanwhile, flash roasting also can be used for laboratory purposes and for the synthesis research of various inorganic powder materials, but the flash roasting furnace is not sold in the market at present, so that the process is very unfavorable for popularization and application in the research field. The technical field does not have a flash roasting furnace for laboratory use at present, and only has a flash roasting furnace for industrial field use. A flash roasting furnace in the field of laboratories needs to be developed for flash roasting treatment in laboratories and research is carried out.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: the simple and convenient small flash roasting equipment is provided for carrying out flash roasting operation in a laboratory, and the blank of domestic products of the type is filled.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a flash roasting furnace is baked over a slow fire in laboratory, its includes gaseous preheater and powder feeder, and the gas outlet of gaseous preheater is connected with the burning furnace over a slow fire after with the discharge gate intercommunication of powder feeder, bakes over a slow fire the discharge gate of burning furnace and connects gas-solid separator, and the top of gas-solid separator is equipped with the gas vent, and the bottom is equipped with the feed opening, and the feed opening is connected with the receiving hopper.
Preferably, the gas inlet of the gas preheating furnace is connected with a gas source, and the gas source is a steel cylinder gas or an air compressor.
Preferably, the gas preheating furnace is an electric heating furnace with controllable temperature, and the upper limit of the gas heating temperature is 300 ℃.
Preferably, the discharge port of the powder feeder is arranged above the gas outlet of the gas preheating furnace, and the gas outlet of the gas preheating furnace is upwards connected with the discharge port and then connected with the feed port at the top of the roasting furnace.
Preferably, the powder feeder adopts a trace powder feeder, the powder feeding amount is 0.1-25g/min, and the powder feeding precision is +/-3%.
Preferably, the gas-solid separator is a cyclone separator.
The powder feeder plays a role of regularly conveying the powder to be flash-roasted, and quantitatively conveying the powder into the roasting furnace at regular time intervals. The discharge port of the powder feeder is connected with the gas outlet of the gas preheating furnace, so that the fed powder is immediately taken away by the gas flow. The gas carrying powder passes through the pipeline heated by the roasting furnace at a higher speed so as to achieve the effect of flash roasting. Separating the flash roasted material by a gas-solid separator to separate gas from solid, emptying the gas and collecting the solid in a material receiving hopper.
The utility model discloses drive the powder by the air current, fast through roasting the burning furnace, reach the effect of accomplishing the calcination fast, then separate gas and powder through the gas-solid separator, then collect the powder that has roasted in the receiving hopper.
The utility model provides a novel flash roasting furnace of laboratory powder processing, it has simplified the structure that industry flash roasting furnace, combines the laboratory demand, carries the powder fast through roasting the furnace with the air current, with gas-solid separator separation powder and air current, collects the powder after the calcination again in the receiving hopper to realize the experimental demand of powder flash roasting, fill present domestic and foreign blank.
Drawings

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 1, for the utility model provides a pair of flash roasting furnace is used in laboratory, it includes gaseous preheater 1 and powder feeder 2, and the gas outlet of gaseous preheater 1 is connected with roasting furnace 3 after with powder feeder 2's discharge gate intercommunication, and the discharge gate of roasting furnace 3 is connected gas-solid separator 4, and gas-solid separator 4's top is equipped with the gas vent, and the bottom is equipped with the feed opening, and the feed opening is connected with receiving hopper 5. And the gas inlet of the gas preheating furnace 1 is connected with a gas source, and the gas source adopts a steel cylinder gas. The discharge hole of the powder feeder 2 is arranged above the gas outlet of the gas preheating furnace 1, and the gas outlet of the gas preheating furnace 1 is upwards connected with the discharge hole and then connected with the feed inlet at the top of the roasting furnace 3. The gas preheating furnace 1 is an electric heating furnace with controllable temperature, and the upper limit of the gas heating temperature is 300 ℃. The powder feeder 2 adopts a trace powder feeder, the powder feeding amount is 0.1-25g/min, and the powder feeding precision is +/-3%. The gas-solid separator 4 is a cyclone separator.
Feeding the powder to be roasted at the feeding speed of 1-25g/min by the powder feeder, wherein the feeding hole is transversely connected with a pipeline of the gas outlet of the gas preheating furnace 1. Then the gas flows from bottom to top, carries the powder from top to bottom to pass through the roasting furnace 3 for quick high-temperature roasting, and then passes through the roasting furnace, and then passes through the gas-solid separator 4, the gas is emptied upwards, and the powder falls into the receiving hopper 5 for collection.
