Abstract
The invention discloses a kind of device improving fluidized bed furnace milling capacity, it is made up of Roots blower, furnace bottom airduct, fluidized bed furnace, high-pressure air hose, air accumulator, Roots blower connects with fluidized bed furnace through furnace bottom airduct, it is provided with blast cap in described fluidized bed furnace, described blast cap, for covering bottom fluidized bed furnace, it is formed around through hole；Described high-pressure air hose one end connects with air accumulator, and the other end stretches in fluidized bed furnace, and the port of export is located on blast cap.Due to the fact that the little hole number of blast cap reduces, orifice size reduces, it is effectively increased blast cap aperture gas speed, effectively raise fluidized bed furnace boiling effect, go out to increase high-pressure blast at nesting box simultaneously, effectively raise fluidized bed furnace furnace bottom pressure, it is suppressed that slag discharge, improve material roasting time in stove, effective raising fluidized bed furnace treating capacity.This apparatus structure is simple, operate steadily, strong adaptability, be effectively improved device efficiency.
Description
Technical field
The present invention relates to smelting industry mechanized equipment technical field, a kind of dress improving fluidized bed furnace milling capacity
Put.
Background technology
Roasting system fluidized bed furnace is for carrying out pretreatment to high sulfur-bearing arsenic complicated golden ore concentrate, owing to raw ore complicated component is many
Become, the especially change of mineral proportion, make fluidized bed furnace furnace bottom pressure wayward, have a strong impact on roasting effect and treating capacity, add
Design scale limited, the milling capacity of fluidized bed furnace can not get effectively improving always.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of device improving fluidized bed furnace milling capacity, simple in construction, fortune
Row is steady, strong adaptability, kinetic energy consume little, can improve Precious Metals Resources level of comprehensive utilization.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme: a kind of fluidized bed furnace milling capacity that improves
Device, is made up of Roots blower, furnace bottom airduct, fluidized bed furnace, high-pressure air hose, air accumulator, Roots blower through furnace bottom airduct with
Fluidized bed furnace connects, and is provided with blast cap in described fluidized bed furnace, and described blast cap, for covering bottom fluidized bed furnace, it is formed around through hole；
Described high-pressure air hose one end connects with air accumulator, and the other end stretches in fluidized bed furnace, and the port of export is located on blast cap.
Further, a diameter of 6mm of described through hole.
Further, described high-pressure air hose is to stretch into through the discharge gate of described fluidized bed furnace.
Further, described high-pressure air hose is provided with valve.
Further, described high-pressure air hose is for being obliquely installed, and fluidized bed furnace outer portion is higher.
Further, described blast cap is oblate cylindrical shell.
Compared with prior art, the invention have the advantages that orifice size reduces owing to the little hole number of blast cap reduces,
It is effectively increased blast cap aperture gas speed, effectively raises fluidized bed furnace boiling effect, go out to increase high-pressure blast at nesting box simultaneously, have
Imitate improves fluidized bed furnace furnace bottom pressure, it is suppressed that slag discharge, improves material roasting time in stove, effectively improves
Fluidized bed furnace treating capacity.This apparatus structure is simple, operate steadily, strong adaptability, be effectively improved device efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention improves the device of fluidized bed furnace milling capacity；
Wherein: 1 Roots blower；2 furnace bottom airducts；3 fluidized bed furnaces；4 blast caps；5 nesting box；6 high-pressure air hoses；7 valves；8 air accumulators.
Detailed description of the invention
Describing the present invention below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not
Protection scope of the present invention is had any restriction effect.
A kind of device improving fluidized bed furnace milling capacity as shown in Figure 1, by Roots blower 1, furnace bottom airduct 2 company of sealing
Connecing, air intake enters fluidized bed furnace 3 by small-bore blast cap 4, and blast cap 4 is oblate cylindrical shell, and blast cap 4 surrounding offer four ∮=
6mm aperture, high-pressure air hose 6 one end stretches into nesting box 5 and down to certain altitude, and exterior line installs the valve of a quantity-adjustable
Door 7, the other end connects with air accumulator 8.
During use, owing to the little hole number of blast cap 4 reduces, aperture diminishes, will further under conditions of entering stove air quantity equally
Improve furnace bottom aperture gas speed, improve material boiling effect in fluidized bed furnace 3, fluidized bed furnace 3 milling capacity can be effectively increased；But due to gas
Speed improves, and makes furnace bottom pressure diminish, and discharge increases, and affects roasting quality, by increasing high-pressure blast material pressing device, effectively stable
Furnace bottom pressure, extends material roasting time, adds treating capacity and roasting effect.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
