Abstract
This invention relates to the technique for preparing tri-cobalt tetroxide powder containing a pneumatic raw material feeder. It comprises: a waste acid tank for collecting waste-acid, a raw material feeding pipeline for roasting furnace, a compressed air feeding pipe connecting waste acid tank, the other end of said pipe being connected to a compressed air source, an air filter in said air feeding pipeline and a pressure regulating valve. On the raw material feeding pipeline equiped is a clean water feeding pipeline, the end of the raw material feeding pipe, through a valve, is connecting the cleaning liquid return- tube, then connecting a cleaning liquid circulation tank, waste acid tank to form a circulation online cleaning system. Advantages are: due to pneumatic feeding raw material, it benefits: continuous roasting, stable feeding of raw material, increasing oxygen content; due to the online circulation cleaning system, it keeps smooth feeding raw material, and increasing the utilization rate of roasting furnace.
Description
Technical field
The present invention relates to the tricobalt tetroxide preparing technical field, particularly a kind of Pneumatic feeding device for preparing the stoving oven of cobaltosic oxide powder.
Background technology
In the preparation process of cobalt oxide, can produce the cobalt compounds of certain density HCl and 140g/L.In preparation process, the ratio regular meeting of HCl progressively increases, and behind the state of reaching capacity, dissolving will stop.In order to keep proceeding of dissolution process, cobalt oxide among the HCl should be extracted, simultaneously acid strength is reduced, need a cover preparation technology and an equipment, the HCl solution that will contain aforementioned proportion is delivered in the preparation facilities, generates tricobalt tetroxide, has also obtained concentration simultaneously and has been about 15% hydrochloric acid, turn back in the dissolution system recycling spent acid solution again.Its roasting process is: the cobalt oxide solution that will contain certain proportion concentration and content is collected in the spent acid jar, sends into preconcentrator with the spent acid pump through waste acid filter, with the pneumatic valve automatic control flow of having regulated.Spent acid is delivered to the preconcentrator top by the preconcentrator recycle pump and is sprayed.Carry out direct heat exchange with the furnace gas (400 ℃) from stoving oven, the part moisture content in the spent acid is evaporated, spent acid solution is concentrated.Spent acid solution after concentrating by the stoving oven feeding pump deliver to the stoving oven top through stoving oven feed pipeline, advance in the stoving oven through spray boom, nozzles spray again.Stoving oven and relevant device thereof play key effect in complete assembly.
There is following defective in the feeding device of existing stoving oven:
Through the waste acid filter feed, the spent acid pump is subjected to mechanical wear and corrosion to preconcentrator easily, thereby causes the fluctuation of flow and pressure with the spent acid pump.In case the spent acid pump is worn and erodes to the degree that can't continue to use, just must scrap, change with new pump.This not only can reduce the operating rate of equipment, and can improve production cost.Therefore must be improved.
Summary of the invention
The object of the present invention is to provide a kind of Pneumatic feeding device that does not have the stoving oven of machinery preparation cobaltosic oxide powder wearing and tearing, that can move continuously for a long time.
The Pneumatic feeding device of the stoving oven of preparation cobaltosic oxide powder of the present invention, comprise spent acid jar, the stoving oven feed pipeline of collecting spent acid, it is characterized in that: have a compressed air inlet pipe to be connected with described spent acid jar, the other end of this compressed air inlet pipe is connected with compressed air source, on this compressed air inlet pipe air filter is arranged, described spent acid jar directly is connected with stoving oven feed pipeline.
Described compressed air inlet pipe is provided with the compressed air pressure variable valve.
Described stoving oven feed pipeline is provided with the clear water suction culvert, and the end of stoving oven feed pipeline is connected with the scavenging solution return line by a valve, and this scavenging solution return line is connected with the clean-out system circulation tank, this
The clean-out system circulation tank is connected with described spent acid jar, forms an online cleaning system of circulation.
Pneumatic feeding device according to the stoving oven of preparation cobaltosic oxide powder of the present invention has following advantage: owing to change the feeding pump feed into pneumatic feeding, stoving oven can be worked continuously, improved the stability of feed, but also can give supplemental oxygen in the stoving oven, add an online cleaning system of circulation again, make stoving oven feed pipeline can keep the material smoothness, thereby further improved the plant factor and the working efficiency of stoving oven.
