Description of drawings
Fig. 1 is the structural representation of the settling vessel that provides of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Referring to Fig. 1, be the structural representation of the settling vessel that provides of the utility model, this settling vessel is made of stillpot 1 and jet pump 2.
Wherein, stillpot 1 is the round barrel shape cavity of sealing, and its upper end is provided with inlet valve 101 and air bleeding valve 102.
Be provided with ring-shaped baffle 3 in the chamber of stillpot 1, the inlet valve 101 that the mozzle 204 of jet pump 2 passes stillpot 1 extends to the upper surface of ring-shaped baffle 3.This ring-shaped baffle 3 is made of outer baffle 301 and Internal baffle 302.Wherein, outer baffle 301 is the funnel structure of both ends open, and its top is inverted cone shape, and the bottom is a round barrel shape, and the diameter of its upper surface is greater than the diameter of lower surface; Internal baffle 302 is the back taper structure of both ends open, and the diameter of its upper surface is greater than the diameter of lower surface.Internal baffle 302 is fixed on the inside of outer baffle 301 by fixture, and stillpot cavity, outer baffle 301 and Internal baffle 302 are on the same central axis.
The external diameter of outer baffle 301 upper surfaces equals the internal diameter of stillpot 1 cavity, and the edge of this upper surface adopts welding or hinged mode to be connected on the internal face of stillpot 1, and ring-shaped baffle 3 and stillpot 1 cavity are on the same central axis.Ring-shaped baffle 3 is divided into two parts up and down with the inner chamber of stillpot 1, and two-part liquid can be connected by the inside and outside passage on the ring-shaped baffle 3 up and down.
Further, stillpot also is provided with agitating device 4 in 1 chamber, and this agitating device 4 is made of shaft 401, blade 402, pump impeller.Shaft 401 is connected with described pump impeller, and shaft 401 vertically places on the central axis of stillpot 1; Blade 402 is fixed on the described shaft 401, and blade 402 places the internal channel of described ring-shaped baffle 3.The Internal baffle 302 common formations of this shaft 401, blade 402, back taper structure stir lifting device.Wherein, shaft 401 vertically places on the central axis of stillpot 1 cavity, and blade 402 is fixed on the shaft 401, and blade 402 places the inside of Internal baffle 302.
During concrete enforcement, the shaft 401 of agitating device 4 is connected with paddle 402, can be by the rotary speed of shaft 401 control blades 402.When blade 402 rotary works, slurry rises to the upper surface of Internal baffle 302 via the internal channel of ring-shaped baffle 3 from Internal baffle 302 lower surfaces; Via the outer tunnel of ring-shaped baffle 3, put the lower surface that end face drops to outer baffle 301 again, thereby realize the continuous circulation of slurry, guarantee the generation of deposit seed from outer baffle 301.
Optionally, in order to make slurry circulation continuously better in groove, during specific design, make the upper surface of a little higher than outer baffle 301 in upper surface of Internal baffle 302, the lower surface of Internal baffle 302 is higher than the lower surface of outer baffle 301.
As shown in Figure 1, the upper end of stillpot 1 is provided with air bleeding valve 102, is used for exhaust.The sidewall of stillpot 1 also is provided with mother liquor outlet valve 103, and this mother liquor outlet valve 103 is used to discharge mother liquor between the upper surface and lower surface of outer baffle 301.The bottom of stillpot 1 is provided with sediment outlet valve 104, is used to export the sediment in stillpot 1 chamber.
In the middle of concrete enforcement, the settling vessel that the utility model provides can be used for preparing coarse grained Nb
2O
5, its idiographic flow is as follows: with niobium liquid (H
2NbOF
5) injecting mixing chamber 201 from first charging aperture 202 of jet pump 2, second charging aperture 203 from jet pump 2 feeds ammonia (NH simultaneously
3).Because the suction function that the miscarriage of niobium liquid is given birth to can be brought ammonia in the mixing chamber 201 of jet pump 1, realize that niobium liquid mixes with giving of ammonia, and be injected into the upper surface of the ring-shaped baffle 3 in the stillpot 1 via the mozzle 204 of mixing chamber 201 bottoms.Because be provided with agitating device 4 in the chamber of stillpot 1, these agitating device 4 rotary works constantly will be expected the oar mixed lifting to liquid level, make the microcosmic mixing of liquid level charging place fine, can not produce local supersaturation.And set ring-shaped baffle 3 in stillpot 1 chamber, and the supporting with it agitating device with castering action 4 are realized slurry circulation continuously between the internal channel of ring-shaped baffle 3, outer tunnel.Agitating device 4 had both played the effect that mixes, and played again to promote the effect that realizes that the oar material circulates in stillpot, and the suspension that has molecule participates in circulation, and in a single day particle grows up, and just sinks to the bottom of stillpot 1, forms oarse-grained sediment.During concrete enforcement, the rotating speed that makes agitating device 4 blades is 60-80 rev/min, and rotating speed is low can not smashed deposit seed.And owing in the groove recycling precipitation reaction heat release (can reach 60 ℃), do not need outer heating just can well not realize deposit seed ageing (slaking) effect, resulting meta particle is thick, hard, do not wrap up mother liquor, adsorb that impurity is few, product purity is high.
The settling vessel that the utility model embodiment provides, jet pump can realize that giving of two kinds of materials mixed and the injection stillpot, be provided with ring-shaped baffle and agitating device in the stillpot, this ring-shaped baffle is made up of Internal baffle and interior plate washer, form inside and outside two passages, the blade of agitating device places the internal channel of ring-shaped baffle, when the blade rotary work, the oar material connects circulation on the inside and outside passage of ring-shaped baffle, guarantee the sedimentary generation of coarse granule.The utility model can be used for preparing the niobium oxide in coarse grain footpath, jet pump can realize that niobium liquid mixes with giving of ammonia, giving mixed oar material injects in the stillpot, the built-in pump impeller agitating device of stillpot has been realized the continuous circulation of oar material in groove, nucleus formation, grain growth have been guaranteed fully, the technical process of precipitation growth and ageing (slaking).The meta particle that is produced is thick, hard, do not wrap up mother liquor, absorption impurity is few, product purity is high, can satisfy the requirement of big capacity multi-layer ceramic capacitor.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
