Further, doublestage horizontal reposition of redundant personnel mixer still includes the gas injection subassembly, and the gas injection subassembly includes gas tank and gas injection pump, and gas tank and gas injection pump are fixed on one-level stirring pond, and during the gas injection pump pours into the thick liquids in the one-level stirring pond with the gas injection in the gas tank, the gas that persists in the gas tank is soluble gas for treating mixed thick liquids.

The soluble gas is dissolved in the slurry after being injected into the slurry, the injected amount reaches the saturated gas amount at the temperature, namely, no more gas can be injected at the temperature, the dissolved gas can be separated out when the pressure is reduced or the temperature is increased, the invention utilizes the principle of separating out the gas by reducing the pressure, a certain amount of gas substances are dissolved in the slurry, the flow rate of the slurry is increased near a stirring impeller, the flow rate is increased according to the characteristics of hydrodynamics, the flow rate is increased in continuous flow, the pressure is reduced, namely, the gas components in the slurry part with large flow speed can separate out the slurry to form small bubbles, moreover, the separation of the bubbles is mostly generated at the position where solid substances are attached, the powder materials which are not mixed yet are in the slurry to be mixed, the powder materials are distributed in the slurry fluid in a lumpy manner, and the gas dissolved in the surrounding fluid is stirred along with the stirring impeller, the pressure is reduced, the powder agglomerates are precipitated to form bubbles near the powder agglomerates, and then in the flowing process, the flow speed is reduced when the powder agglomerates flow away from the stirring wheel, the fluid pressure is increased, or the fluid pressure is increased when the powder agglomerates are extruded by the stirring wheel in the processing direction of the stirring wheel, and the solubility of the fluid for the gas returns to the degree of completing the dissolution, so that the bubbles are quickly broken out, the cavity at the bubble position is quickly filled by the surrounding fluid, shock waves are generated at the bubble position, the adjacent powder agglomerates which are not stirred uniformly are scattered by the shock and enter the surrounding fluid to form uniformly mixed slurry, the process always exists after the gas injection is completed, the gas selection which affects the stirring efficiency is proper, the specific gas selection is different according to the different components of the slurry, and the selection principle is that: the solubility is not small, if the solubility is large, a large amount of injected gas cannot reach the saturation condition, for example, the ammonia gas injected into water consumes a large amount of ammonia gas, the solubility cannot be too small, otherwise, the injected gas is saturated quickly, redundant gas floats up quickly at the gas injection position, only a small amount of gas is insensitive to pressure change, and only a little bubbles can be separated out after the pressure is reduced, so that the stirring effect of bubble collapse is influenced.

Further, doublestage horizontal reposition of redundant personnel mixer still includes the blender, the blender sets up on the flow path of thick liquids, the blender includes the urceolus, the inner tube, awl mouth filter screen and flight, urceolus and inner tube coaxial setting, interbedded axial one side sets up the flight of connecting urceolus inner wall and inner tube outer wall between urceolus and the inner tube, the flight axis is the inner tube axis, the interbedded department at the flight side between urceolus and the inner tube sets up the awl mouth filter screen, the inner tube includes the convergent section, choke and drainage tube, the convergent section sets up the one side at the choke, the convergent section macrostoma is outwards, awl mouth filter screen inclination is the same with the convergent section inclination, awl mouth filter screen microcurrent end is connected with the convergent section macrostoma, the drainage tube extends radially from the choke wall, the drainage tube is kept away from the choke and is stretched into in the interbedded between urceolus and the inner tube.

The mixer is an efficient mixing component, when fluid slurry passes through the mixer, large powder which is not uniformly mixed is intercepted by the cone-mouth filter screen and guided to the inner cylinder, the uniform slurry can smoothly pass through the cone-mouth filter screen and enter an interlayer region between the inner cylinder and the outer cylinder, after entering the interlayer, the slurry rotates and flows along with the diversion of the spiral sheet, during the rotation process, the slurry with high concentration has large viscosity and low rotation speed, the slurry with low concentration has small viscosity, the rotation speed is increased more, the micro-cluster with high rotation speed is subjected to larger centrifugal force, therefore, after the slurry which passes through the cone-mouth filter screen is subjected to rotation and transduction by the same spiral sheet, the fully mixed slurry can generate a micro-layering effect in the interlayer of the inner cylinder and the outer cylinder, thin slurry is positioned at the radial outer end, namely closer to the inner wall of the outer cylinder, and thick slurry is positioned at the radial inner end, namely, the slurry is closer to the outer wall of the inner cylinder, and the slightly layered slurry flows backwards along the axial direction; the slurry entering the inner cylinder has a tapered section, the flowing speed is higher and higher, the maximum flow speed is achieved in the throat pipe, the flow speed is high, the pressure is low, and the pressure is lower than that of the fluid in the interlayer of the inner cylinder and the outer cylinder, so the fluid in the inner cylinder and the outer cylinder can enter the throat pipe along the drainage tube, the powder agglomerate which is not uniformly stirred can be filtered by the tapered filter screen and guided into the flow channel in the inner cylinder, the drainage tube extends into the position close to the inner wall of the outer cylinder, the thin thick slurry with lower concentration which is centrifugally layered is drained from the inner cylinder and the outer cylinder, and the thin thick slurry enters the throat pipe to impact the powder agglomerate in the vertical flowing direction, so that the thin thick slurry is crushed and mixed with the powder agglomerate to form the slurry with proper concentration, and the efficient stirring effect is achieved.

Preferably, the pipeline is a siphon pipe, and the mixer is arranged at the descending section in the siphon pipe.

The siphon can make the gas in the slurry fully separated out when passing through the siphon, when the slurry rises in the siphon, the pressure is gradually reduced, the speed of pressure reduction is different along with the difference of the density of the slurry, for example, the pressure corresponding to ten meters of water column is an atmospheric pressure, for the gas injected in the slurry, the bubble can be separated out only by slightly reducing the pressure, the more the pressure is reduced, the more the bubble is separated out, the longer the rising section of the siphon is, the more the bubble content is at the highest point, then, in the descending section, the slurry pressure is gradually increased, the bubble dissolution and collapse are carried out, the bubble impact homogenizing is carried out, and the mixer arranged in the descending section of the siphon can improve the mixing effect because the powder block mass can not only be filtered and guided into the inner cylinder by the cone-mouth filter screen, but also because the outer surface is the interface between the slurry and the powder, the boundary is the preferred position for the air bubble to separate out, namely, when the powder agglomerate rises along with the slurry in the rising section, the outer surface separated gas wraps the powder agglomerate, when the falling section enters the inner cylinder, the powder agglomerate and the slurry around the powder agglomerate are separated by the gas layer, so that the powder agglomerate is better filtered and separated by the cone-shaped filter screen, after the powder agglomerate enters the inner cylinder, the outer surface of the powder agglomerate is fully exposed, and therefore when the thin slurry in the interlayer of the inner cylinder and the outer cylinder impacts the powder agglomerate through the drainage tube, the powder agglomerate can be fully contacted, and the mixing effect is enhanced. The top of the siphon is provided with a vacuum pipe and a control valve for establishing and disconnecting the siphon process.

As another preferred scheme, the double-stage horizontal split-flow stirring machine further comprises a translation drive, the tail portions of the mixers are symmetrically connected in an end-to-end mode, the axial lines of the mixers are parallel, the stacks form a disc-shaped component, the disc-shaped component formed by the mixers is placed in the secondary stirring tank, the translation drive is installed on the side wall of the secondary stirring tank, and the translation drive drives the mixers to perform translation motion in the secondary stirring tank along the length direction of the secondary stirring tank.

Compared with the single mixer which is arranged in the siphon and only flows once, the structure connects the tail of the mixer to the tail so as to allow bidirectional flow, then drives a group of stacked mixers to move back and forth in the secondary stirring tank through translation driving, the slurry in the secondary stirring tank is efficiently mixed once when passing through the primary mixer, the efficient stirring capacity of the mixer is fully exerted, gas is separated out in the mixer, and in the process that the flow speed of the slurry entering the inner cylinder is increased and the pressure is reduced in the tapered section, a gas layer is preferentially separated out around powder agglomerates in the process, although the degree of pressure reduction is lower than that in the siphon, the frequency of fluid passing through the mixer is increased, and the mixing effect is better.

Furthermore, the gas reserved in the gas box is carbon dioxide, the chemical activity of the carbon dioxide is relatively low, the solubility is moderate, and the carbon dioxide is quickly separated out when the pressure is reduced, so that the method is an applicable gas selection for mixing most of slurry.

The first-stage stirring tank and the second-stage stirring tank are arranged on a unified channel steel base. The channel-section steel base provides a unified mounted position for each part of device, only need during transport and the installation unable adjustment base can.
