Abstract
The utility model discloses a manganese carbonate pyrolyzer, comprising a casing body, a hollow rotating shaft, a helical blade and a breathing pipe. The manganese carbonate is led through a feed port, and mixture air which is preheated to reaction temperature and comprises O-[2] is led through a rotating shaft hole into the manganese carbonate pyrolyzer to be reacted, which can cause the MnCO-[3] and the O-[2] to be thoroughly contacted; the temperature is uniformly controlled, reaction condition is stable, and the pyrolysis is thoroughly carried on. The utility model produces the manganese dioxide which is provided with a gamma a beta crystal structure with good discharge performance, the utility model has the advantages of simple device structure, few investment, high-use rate of O-[2] and heat, easy operation, good product quality and low cost, and the scale of the utility model can be large or small.
Description
The utility model relates to a kind of device of manganese carbonate pyrolysis reaction.
People utilize manganous carbonate at a certain temperature and oxygen (or air) and suitable quantity of water steam carry out pyrolytic reaction, produce chemical manganese bioxide powder (CMD) or chemically reactive manganese dioxide powder (AMD) with discharge performance, its basic chemical equation is:
Known pyrolytic reaction device and the technology that is adopted are that the gas mixture of oxygen (or air) and water vapor is fed in the stainless steel electric heating rotary kiln, make the manganous carbonate in the kiln carry out above-mentioned pyrolytic reaction, obtain required manganese dioxide powder.But, because oxygen (or air) is to be heated to the required temperature of manganese carbonate pyrolysis in the burner hearth of rotary kiln with the cold air stream of water vapor, and this air-flow only sails on the surface of the bed of material, certainly will bring two shortcomings like this: the one, and the cold air stream heat temperature raising needs the time, O
2With water vapor and MnCO
3Can not contact fully, pyrolytic reaction is difficult to carry through to the end; The 2nd, with the rotation of rotary kiln, temperature inequality and fluctuation are bigger in the bed of material table.The unsteady pyrolysis environment of this variation causes the pyrolysis of manganous carbonate irregular, and the crystal growth of the Manganse Dioxide that generates after the pyrolysis also changes thereupon, is difficult to obtain the crystalline structure of good γ type of discharge performance or β type, thereby causes quality product low, and it is bigger to fluctuate.Use electrically heated, also increased energy consumption and cost.In addition, revolution effective capacity of kiln utilization ratio and heat exchange utilization ratio are all lower, the complex structure of industrial equipment, and the cost height, investment is big, is difficult to operation, thereby makes that the production cost of manganese dioxide powder is higher.
Task of the present utility model is exactly to design a kind of manganese carbonate pyrolysis reaction unit of novelty, so that utilize this device with manganese carbonate pyrolysis, produces the manganese dioxide powder of high discharge performance.
Explore repeatedly for many years through the inventor, the foregoing invention task obtains basic the solution.Device of the present utility model has one one end that opening for feed is arranged, the other end has the columnar housing of discharge port, there is bearing at the housing two ends, the bearing upper support has turning axle, one end of turning axle stretches out housing, be fixed with screw-blade on the turning axle, turning axle is by the outer drive mechanism rotation of housing, turning axle is hollow, through hole is arranged on the turning axle, be preferably between the vertical section of each pitch of screw-blade on the turning axle, fix a ventpipe at least, pore is arranged on the ventpipe, and the through hole on the turning axle makes ventpipe be communicated with the center cavity of turning axle.The helix angle of screw-blade can be selected between 5 °～65 °, and the screw-blade of low pitch angle can be used in the device of the vertical installation of circular cylindrical shell, and the screw-blade of large helix angle then is usually used in the horizontally-mounted device.Housing upper end at this device of vertical installation can also be provided with venting hole, in order to the CO that produces in the discharging reaction
2Gas and waste gas.Grow, require the long device of circular cylindrical shell for reaction process, housing, turning axle and/or screw-blade can be formed by connecting by several sections respectively.
Because manganous carbonate in device of the present utility model, can make O under controlled, stable reaction conditions
2With MnCO
3Carry out sufficient pyrolytic reaction, when particularly adopting the device of two playscript with stage directions utility models to react by two sections pyrolytic processes, it is thorough that pyrolytic reaction more becomes, thereby can obtain the high discharge performance manganese dioxide powder of γ type or β type, its production cost reduces, production efficiency improves, and constant product quality has shown superiority of the present invention.Pyrolysis installation for manganous carbonate of the present invention is simple in structure, and industrial scale is changeable, and adaptability is strong, easy-to-operate, low cost of manufacture.Not only be suitable for the pyrolysis of manganous carbonate, also be suitable for the oven dry and the pyrolysis of other material (as carbonates such as aluminium carbonate, zinc carbonates).
Describe below in conjunction with embodiment and accompanying drawing.
Fig. 1 is that Fig. 2 is its sectional view along the H-H face according to the structural representation of a kind of pyrolysis installation for manganous carbonate of the utility model design.
Referring to Fig. 1 and Fig. 2, pyrolytic reaction device of the present invention comprises a columnar housing 1.One end of housing 1 (can be the upper end, also can be the lower end) has opening for feed 11, and the other end has discharge port 12.The both ends of housing 1 also have bearing 2, in order to supporting rotating shaft 3, allow it rotate flexibly.One end of turning axle 3 stretches out outside the housing 1, so that driving mechanism 4 is installed, drives its rotation thereon.Turning axle 3 is hollow, and there is cavity 31 at the center, on the turning axle 3 in housing 1 through hole 32 is arranged, be fixed with screw-blade 33 on the turning axle 3, this screw-blade 33 can be selected entity face type for use, also can select for use belt face type or the blade face type, its helix angle can be selected between 5 °～65 °.Between the vertical section of each pitch of screw-blade 33 on the turning axle 3, a ventpipe 34 is housed at least, can adorn two, three or four according to the needs of reaction, through hole 32 on the turning axle 3 makes ventpipe 34 be communicated with the center cavity 31 of turning axle 3, pore 35 is arranged on the ventpipe 34, and the quantity of pore 35 is also decided according to the situation of reaction.Upper end at this device case can also be provided with venting hole 13, is convenient to discharge or reclaim the carbon dioxide that produces in the reaction, remaining O
2, water vapor and waste gas, utilize wherein contained CO
