Abstract
The utility model relates to roasting equipment. The roasting equipment comprises a hearth and a reaction vessel arranged inside the hearth, wherein the bottom of the reaction vessel is provided with a multi-hole false bottom, the top of the reaction vessel is provided with an external exhaust pipeline, the lower portion of the multi-hole false bottom is connected with a high-pressure draft chamber, and the bottom of the high-pressure draft chamber is provided with an air inlet pipe which is provided with an airflow pump. Small porcelain beads are evenly laid on the multi-hole false bottom, the external exhaust pipeline is provided with an air filter which is provided with an air inlet pipe communicated into the high-pressure draft chamber, the air filter is provided with a waste gas pipeline, and useless waste gas can be exhausted through the waste gas pipeline. The roasting equipment can overcome the defects that a traditional muffle furnace can not be sealed, so that the roasting effect of furnace charges is poor and heat sources are wasted, and can enable the useless waste gas to be exhausted and enable useful high-temperature gas to enter the high-pressure draft chamber again, therefore, circulation is formed, roasting efficiency is improved, and heat is saved.
Description
Technical field
The utility model relates to a kind of roasting apparatus, is specially a kind of be used to the breeze roasting apparatus that needs atmosphere.
Background technology
Roasting refers to ore, concentrate or metallic compound not added or with addition of certain material, be heated to the fusing point that is lower than furnace charge, makes the metallurgical process of furnace charge generation oxidation, reduction or other chemical changes.Roasting belongs to the preparation work before pyrometallurgy or the hydrometallurgy, and its purpose is to change the chemical composition of extracting object in the furnace charge, so that next step processing.At present, the main roaster that supplies laboratory, industrial and mining enterprises, R﹠D institution to do determination of elemental analysis and general small-sized furnace charge roasting experiment mostly is Muffle furnace, traditional Muffle furnace generally all is the closed thermal bake-out that adds, but some breeze need roasting under certain atmosphere, this has to oven door opening, directly is communicated with the external world, so not only roasting effect difference and length consuming time, and the heat energy utilization rate is low, exists the waste of the energy.
The utility model content
At the shortcoming of above-mentioned prior art, the utility model provides the good heat energy utilization rate of a kind of roasting effect high atmosphere roasting apparatus.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of roasting apparatus, comprise burner hearth and be arranged on the interior reaction vessel of burner hearth, described container bottom is provided with the false end of cellular, container top is provided with outer discharge duct, the false bottom of described cellular is connected to the high pressure draught chamber, bottom, described high pressure draught chamber is provided with air inlet pipe, and the pneumatic pump that pumps into air-flow is installed on the described air inlet pipe.
Further, described porous evenly is equipped with little porcelain bead at false the end.
As preferably, described outer discharge duct is communicated with described airflow chamber.
As preferably, described outer discharge duct is provided with the gas filtration machine, and the waste gas after the gas filtration machine will filter by exhaust piping is discharged.
The utility model compared with prior art has following advantage: reaction container bottom described in the utility model is provided with the false end of porous, container top is provided with outer discharge duct and can makes required air-flow enter reaction vessel furnace charge is protected or catalytic reaction, has overcome to use traditional Muffle furnace not seal to make shortcomings such as furnace charge roasting effect difference and waste thermal source; Adopt the air inlet end face high pressure draught chamber bigger than the end face of giving vent to anger to make air-flow reach certain pressure intensity and can better touch furnace charge, and discharge from the reaction vessel top; Evenly be equipped with little porcelain bead prevents from leaking under the material in the roasting process at false the end; Outer discharge duct is provided with the gas filtration machine can make waste gas useless discharge, and useful high-temperature gas is fed the high pressure draught chamber again, forms circulation, has not only improved roasting efficient but also has saved heat energy.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with specifically illustrating and embodiment, further set forth the utility model.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to figure 1, the utility model embodiment provides a kind of roasting apparatus, comprise burner hearth 1 and reaction vessel 2, described reaction container bottom is provided with the false end 21 of cellular, the reaction vessel top is provided with outer discharge duct 22, the false bottom of described cellular is connected to high pressure draught chamber 3, bottom, described high pressure draught chamber is provided with air inlet pipe 4, the pneumatic pump 5 that pumps into air-flow is installed on the described air inlet pipe, described porous evenly is equipped with little porcelain bead at false the end, described outer discharge duct is provided with gas filtration machine 6, and described gas filtration machine is provided with the air inlet pipe 4 that feeds described high pressure draught chamber, and described gas filtration machine is provided with exhaust piping 7.
In the utility model; the air-flow trend is shown in arrow among Fig. 1; the required extraneous air-flow of roasting (the general feeding is air) enters the high pressure draught chamber through pneumatic pump from air inlet pipe; end face is big because high pressure draught chamber air inlet end face ratio is given vent to anger; make air-flow increase at outlet side pressure; gas after the supercharging fully contacted with the material of required roasting by the false end of the cellular that evenly is equipped with little porcelain bead; material is protected or catalysis or participate in reaction directly; the new air-flow that forms is discharged from the outer discharge duct at reaction vessel top afterwards; enter the gas filtration machine; the gas filtration machine filters gas; useless waste gas is discharged from exhaust piping; and the high-temperature gas of useful component is entered the high pressure draught chamber by air inlet pipe; and mix with the new gas that enters through pneumatic pump, tentatively heat new gas, form circulation; improved the heat energy utilization rate like this, also overcome simultaneously and used traditional Muffle furnace not seal to make shortcomings such as furnace charge roasting effect difference and waste thermal source.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
