Abstract
The invention discloses a kind of devices for improving fluidized bed furnace milling capacity, it is made of Roots blower, furnace bottom air hose, fluidized bed furnace, high-pressure air hose, air accumulator, Roots blower is connected to through furnace bottom air hose with fluidized bed furnace, blast cap is equipped in the fluidized bed furnace, the blast cap is that lid is closed in boiling furnace bottom, is surrounded by through-hole thereon；Described high-pressure air hose one end is connected to air accumulator, and the other end protrudes into fluidized bed furnace, and outlet end is located on blast cap.The present invention is reduced due to the small hole number of blast cap, orifice size reduces, effectively increase blast cap aperture gas velocity, effectively raise fluidized bed furnace boiling effect, go out to increase high-pressure blast in nesting box simultaneously, effectively raises fluidized bed furnace furnace bottom pressure, it is suppressed that slag discharge, calcining time of the material in furnace is improved, it is effective to improve fluidized bed furnace treating capacity.The apparatus structure is simple, runs smoothly, is adaptable, effectively improving device efficiency.
Description
Technical field
The present invention relates to smelting industry mechanized equipment technical field, especially a kind of dress for improving fluidized bed furnace milling capacity
It sets.
Background technique
Roasting system fluidized bed furnace is for pre-processing high sulfur-bearing arsenic complicated golden ore concentrate, since raw ore complicated component is more
Become, the especially variation of mineral specific gravity, keeps fluidized bed furnace furnace bottom pressure not easy to control, seriously affect roasting effect and treating capacity, add
Design scale limited, the milling capacity of fluidized bed furnace cannot be improved effectively always.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of device for improving fluidized bed furnace milling capacity, structure is simple, transports
Row is steady, adaptable, kinetic energy consumption is small, can improve Precious Metals Resources level of comprehensive utilization.
In order to achieve the above-mentioned object of the invention, the present invention is the following technical schemes are provided: a kind of improve fluidized bed furnace milling capacity
Device is made of Roots blower, furnace bottom air hose, fluidized bed furnace, high-pressure air hose, air accumulator, Roots blower through furnace bottom air hose with
Fluidized bed furnace connection, the fluidized bed furnace is interior to be equipped with blast cap, and the blast cap is that lid is closed in the furnace bottom that boils, and is surrounded by through-hole thereon；
Described high-pressure air hose one end is connected to air accumulator, and the other end protrudes into fluidized bed furnace, and outlet end is located on blast cap.
Further, the diameter of the through-hole is 6mm.
Further, the high-pressure air hose is that the discharge gate through the fluidized bed furnace protrudes into.
Further, the high-pressure air hose is equipped with valve.
Further, the high-pressure air hose is to be obliquely installed, and fluidized bed furnace outer portion is higher.
Further, the blast cap is oblate cylindricality shell.
Compared with prior art, the invention has the following advantages that orifice size reduces since the small hole number of blast cap is reduced,
Blast cap aperture gas velocity is effectively increased, fluidized bed furnace boiling effect is effectively raised, while going out to increase high-pressure blast in nesting box, has
Effect improves fluidized bed furnace furnace bottom pressure, it is suppressed that slag discharge improves calcining time of the material in furnace, effective to improve
Fluidized bed furnace treating capacity.The apparatus structure is simple, runs smoothly, is adaptable, effectively improving device efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the device that the present invention improves fluidized bed furnace milling capacity；
Wherein: 1 Roots blower；2 furnace bottom air hoses；3 fluidized bed furnaces；4 blast caps；5 nesting box；6 high-pressure air hoses；7 valves；8 storages
Gas tank.
Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings., the description of this part be only it is exemplary and explanatory, do not answer
There is any restriction effect to protection scope of the present invention.
A kind of device of raising fluidized bed furnace milling capacity as shown in Figure 1 is connected by Roots blower 1, the sealing of furnace bottom air hose 2
Connect, air inlet by small-bore blast cap 4 enter fluidized bed furnace 3, blast cap 4 be oblate cylindricality shell, and 4 surrounding of blast cap open up there are four ∮=
6mm aperture, 6 one end of high-pressure air hose protrude into nesting box 5 and to down toward certain altitudes, and exterior line installs the valve of a quantity-adjustable
Door 7, the other end is connected to air accumulator 8.
In use, aperture becomes smaller since the small hole number of blast cap 4 is reduced, it will be further under conditions of equally entering furnace air quantity
Furnace bottom aperture gas velocity is improved, material boiling effect in fluidized bed furnace 3 is improved, 3 milling capacity of fluidized bed furnace can be effectively increased；But due to gas
Speed improves, and furnace bottom pressure is made to become smaller, and discharge increases, and influences roasting quality, effective to stablize by increasing high-pressure blast material pressing device
Furnace bottom pressure, extends material calcining time, increases treating capacity and roasting effect.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
