Abstract
The present invention discloses a preparation method of zinc powder and a preparation device thereof. In the processing process of the zinc powder, raw material zinc is conveyed to a rectifying tower (2) provided with a high temperature tower tray after being melted, is atomized to be zinc vapor and is rectified, and impurity removal and purification are carried out according to the difference of the melting points and the specific gravity of constituents; then, the zinc vapor is guided in a main condenser (3) to be rapidly condensed, and zinc powder is discharged at one end whose temperature is high of the main condenser (3) and is conveyed to a pressure balance condenser (5) to be cooled down. The ultrafine powder is settled down to a fine powder groove (11), and zinc powder discharged at one end whose temperature is low of the main condenser (3) is classified by an ultrafine classifying separator (4) to separate the ultrafine and ultrapure zinc powder. Then, the ultrafine and ultrapure zinc powder is conveyed to a ball mill with inert gas protection to be milled in a dry mode, and the spherical zinc powder is squeezed to be scaly zinc powder. The present invention classifies the rough zinc and powder and the fine zinc powder to obtain the ultrafine and ultrapure zinc powder, the uniformity of the zinc powder is increased, the zinc powder is difficult to oxidize in the process of ball milling, and the roughness of the scaly zinc powder can be controlled.
Description
Technical field
The present invention relates to a kind of preparation facilities of zinc powder.
Background technology
The preparation of existing zinc powder is that zinc ingot metal is melted in zinc-melting pool, directly obtains zinc powder by rectifying tower and water cooler cooling then, and the zinc powder thickness that this method obtained mixes, and adopts coal-fired method of heating to bring certain pollution to environment simultaneously.
Summary of the invention
For the thickness zinc powder is carried out stage treatment, obtain ultra-fine ultrapure zinc powder, improve the uniformity coefficient of zinc powder, the invention provides the preparation facilities of the zinc powder that a kind of fineness is evenly distributed.
The preparation facilities of a kind of zinc powder of the present invention, it mainly is made up of zinc-melting pool, rectifying tower, main condenser, super-fine classified condenser and pressure equilibrium condenser, meal groove and fine powder groove; The zinc-melting pool bottom is provided with slag-drip opening, rectifying tower is the hole by a side, opposite side is tabular staggered being formed by stacking of silicon carbide column plate, the rectifier outlet is communicated with main condenser, in the middle of the main condenser is cavity, it between cavity and outer wall cooling water sandwich, main condenser upper top front exports before being provided with zinc powder, be connected with the zinc powder transfer lime between outlet and pressure equilibrium condenser before the zinc powder, after being provided with zinc powder, main condenser upper top back exports, be connected with the zinc powder transfer lime between outlet and super-fine classified condenser behind the zinc powder, be connected with pressure equilibrium zinc powder transfer lime between super-fine classified condenser and the pressure equilibrium condenser; The main condenser bottom is provided with the meal groove, and super-fine classified condenser is provided with the fine powder groove, and the pressure equilibrium condenser is provided with the fine powder groove.
Also be provided with blue-gas generator in the device, its water-gas transfer lime is connected with zinc-melting pool and rectifying tower.
Adopt this device to make zinc powder, rectifying tower is that hole, opposite side are tabular staggered being formed by stacking of silicon carbide column plate by a side, guaranteed the sufficient sedimentation of impurity, main condenser chuck cooling water control temperature variation, make zinc fume directly change solid into, be the meal groove that the thicker zinc powder of granularity drains into the bottom respectively, remaining then delivers to super-fine classified condenser or pressure equilibrium condenser from the forward and backward outlet at main condenser top, is cooled to the ultra-fine ultrapure zinc powder of even particle size distribution.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of zinc powder preparation facilities of the present invention figure.
Embodiment
According to shown in Figure 1, the present invention mainly is made up of zinc-melting pool 1, rectifying tower 2, main condenser 3, super-fine classified condenser 4 and pressure equilibrium condenser 5, meal groove 9 and fine powder groove 10,11; Zinc-melting pool 1 bottom is provided with slag-drip opening, rectifying tower 2 is the hole by a side, opposite side is tabular staggered being formed by stacking of silicon carbide column plate, outlet enters main condenser 3 to zinc fume from rectifying tower 2 tops, in the middle of the main condenser 3 is cavity, it between cavity and outer wall cooling water sandwich, main condenser 3 upper top fronts export before being provided with zinc powder, outlet and 5 of pressure equilibrium condensers are connected with zinc powder transfer lime 6 before the zinc powder, after being provided with zinc powder, main condenser 3 upper top back export, outlet and 4 of super-fine classified condensers are connected with zinc powder transfer lime 7 behind the zinc powder, are connected with pressure equilibrium zinc powder transfer lime 8 between super-fine classified condenser 4 and the pressure equilibrium condenser 5; Main condenser 3 bottoms are provided with meal groove 9, and super-fine classified condenser 4 bottoms are provided with fine powder groove 10, and pressure equilibrium condenser 5 bottoms are provided with fine powder groove 11.
Raw material zinc is put into zinc-melting pool 1 make its fusing, cadmia is discharged from the slag-drip opening of zinc-melting pool 1 bottom.Zinc fume enters and carries out rectifying in the rectifying tower 2, makes its fusing point that utilizes each component different with proportion, carries out removal of impurities, purification; Then zinc fume is introduced sharply being condensed into zinc powder in the main condenser 3, outlet and back outlet before main condenser 3 is provided with, temperature out is higher before the main condenser 3, and zinc powder is delivered to 5 coolings of pressure equilibrium condenser through zinc powder transfer lime 6, makes ultrafine powder be deposited to fine powder groove 11; Main condenser 3 back temperature outs are lower, and zinc powder is delivered to super-fine classified condenser 4 through zinc powder transfer lime 7 and carried out classification, makes ultrafine powder be deposited to fine powder groove 10.In order to keep the balance of system, between super-fine classified condenser 4 and pressure equilibrium condenser 5 tops, set up balance zinc powder transfer lime 8, in case zinc powder transfer lime 6 or zinc powder transfer lime 7 flows are excessive, then can be by 8 shuntings of balance zinc powder transfer lime.Main condenser 3 front sides and back side lower part respectively are provided with a meal outlet, and thicker zinc powder is delivered to respectively in the meal groove of dividing into 9 relatively.For reducing environmental pollution, in device, set up blue-gas generator, its water-gas sends into zinc-melting pool 1 and rectifying tower 2 usefulness water-gas heat.
