Abstract
The utility model relates to a fluidized-bed oxidation oven for preparing chemical-grade manganese oxide. The enlarging angle of the enlarging part of the upper part of an oven body is 45 DEG. A reduction angle is 30 DEG. A pattern plate is arranged in the middle of the cylinder part in the middle of the oven body. Umbrella-shaped air caps are arranged on the holes of the pattern plate. Each air cap is respectively provided with an air inlet channel and four air out channels. Thus, hot air can be well and evenly dispersed. The particles of manganese carbonate can be well boiled in the fluidized bed. Thereby, the particles of the manganese carbonate can rapidly react with oxygen in air. Thus, manganese oxide is generated. The content of the manganese oxide can reach 75%. The utility model which is a novel oxidation oven for manufacturing batteries and other manganese oxide used for industries has the advantages of simple structure, easy making, stable operation, and high productivity efficiency.
Description
The utility model relates to the structure of fluidized bed type oxidation furnace, particularly the structure of the fluidized bed type oxidation furnace of preparation chemical grade manganese oxide.
As everyone knows, manganese oxide, particularly the γ manganese monoxide is the primary raw material of battery, at present, industrial modal preparation method adopts manganese carbonate high temperature to be cleaved into manganese monoxide, is reoxidised into the method for manganese dioxide, the shortcoming that this method is produced is that product manganese dioxide is not γ-type crystal, if as battery raw material, its discharge performance is bad like this, and battery efficiency is low, next is that product proportion is low, same volume charging down is few, and battery is also lower, and shortcoming is more on technology, as long flow path, the equipment complexity, investment is many or the like, remains further to be reformed.
The purpose of this utility model is to provide a kind of oxidation furnace of fluidized bed type, can directly make manganese carbonate at high temperature with empty oxygen in oxygen reaction prepare qualified γ-type manganese oxide.
Embodiment of the present utility model is as follows: the housing of (1) oxidation furnace partly is made up of expansion section, the middle cylinder portion on top and the tapered portion three of going to the bottom.The widening angle of expansion section, top is 45 °, and angle of throat is 30 °; The feed pipe of middle cylinder portion all is connected with cylindrical portion with 45 with discharge nozzle.(2) the inner and tapered portion junction of going to the bottom of the middle cylinder portion of oxidation furnace is provided with a card, and 800～1200 apertures (can decide according to output) are arranged on the card, and aperture is with diamond array, and two pairs of relative angles respectively are 60 ° and 120 °.(3) outside of the middle cylinder portion of oxidation furnace is provided with the resistance wire heating jacket, can make the interior temperature of charge of stove rise to 370～400 ℃ in one hour.(4) each expands a nut is arranged on each aperture of card, the cowl of can screwing in each nut, and there is a passage at its center, and the lower end of this passage communicates with the aperture of card, the upper end promptly is divided into four outlet passageways equably in the bottom of umbrella hood.(5) tapered portion of going to the bottom of oxidation furnace is provided with an air inlet pipe, and the exit of this air inlet pipe is equipped with the dispersion plate of a plurality of apertures.
Pass through said structure, air blasts earlier that hot water by about 70 ℃ carries out the aperture of the laggard entering plate of humidification and the tapered portion of going to the bottom that enters oxidation furnace equably by air blast, respectively enter cowl by the aperture on the card, each is divided into four bursts of middle cylinder portions that enter oxidation furnace equably again, owing to be equipped with 800～1200 cowls on this card, the hot blast that enters like this disperses 4 multiples again again, 3000-4800 shallow bid air outlets are promptly arranged, like this, can be the seethe with excitement contact of shape of the manganese carbonate in the stove (general granularity be about 180-220 orders) granule, because the continual renovation of air and solids contact-making surface, manganese carbonate is oxidized equably again rapidly and become manganese oxide.
Following preference is described in detail the utility model in conjunction with the accompanying drawings, but does not mean that restriction scope of the present utility model.
Fig. 1 is the fluidized bed type oxidation furnace sketch of preparation manganese oxide of the present utility model.
Fig. 2 is the cowl sketch.
Fig. 3 is an aperture Pareto diagram on the card.
Hot blast carries out humidification (not drawing among the figure) enters oxidation furnace then by air inlet 1 and dispersion plate 2 thereof the tapered portion 6 of going to the bottom by the first hot water by 70 ℃ ± 5 ℃ of air blast, up enter the aperture 4 of card 3 then, the per share hot blast of aperture 4 is divided into 4 shallow bids by cowl 5 again and sprays, and blast cap 5 is the nuts that are tightened against the aperture 4 that expands on card 3.General blast is 0.3-0.5kg/cm
2The manganese carbonate particle of heaping on card 3 is floated form the boiling shape, energising by resistance silk heating jacket 17 makes under the temperature of 370-400 ℃ of stove inherences, rapidly reaction and become manganese oxide of oxygen in manganese carbonate and the air, by discharge nozzle 7 product is discharged out of the furnace, reacted hot blast then rises in the middle rounded portions 8 of oxidation furnace with the carbon dioxide that reaction generates, enter the expansion section, top 9 of oxidation furnace, the air-flow deceleration energy returns in the fluid bed institute's entrained solid grain sedimentation, at last, waste gas is then discharged by exhaust outlet 10.First half place in the middle cylinder portion 8 of oxidation furnace is provided with manganese carbonate feed pipe 11, and this pipe and middle cylinder portion 8 link to each other with 45.Middle and lower part in the middle cylinder portion of oxidation furnace is provided with thermo detector 12, so as to observe and the control stove in temperature.This oxidation furnace is continuous feed, discharging continuously, and its efficient is quite high, and manganese oxide can reach more than 75% in the product generally speaking.
Consult the cowl 5 among Fig. 2, as seen behind its central passage 13 air intakes, evenly be divided into four outlet passageways 14 again and discharge outside the blast cap, 15 the one-tenths umbrella shapes in the top of cowl 5 are convenient to make the solids inflow and are not piled up, and also have finely dispersed effect.
The advantage of the card aperture Pareto diagram among Fig. 3 is that aperture 4 is evenly distributed, good dispersion, and resistance is little.
The utility model has the advantages that:
1. fluidized state is splendid in the stove, but the product manganese oxide of outlet up to 75%, More than.
2. cowl can fill and can roll over, and is convenient to change.
3. hot blast is evenly distributed, stable operation.
4. simple in structure, easy to make.
