Shi Buzai is illustrated one by one, is described collectively herein.
Referring to Figure 1, Fig. 1 is the schematic diagram of solid and liquid mixing equipment 10 in an embodiment of the present invention, described to set
Standby 10 include at least one solid feeder 101, at least one fluid Supplying apparatus 102, liquid distributor chamber 103, solid is defeated
Send room 104 and screw rod drawing-in device 1041, mixing chamber 105 and rotor chamber 106.
In the present embodiment, mixed solid is needed to store and supply described solid by the solid feeder 101
Body conveying chamber 104；Many kinds of solids can be passed through a solid feeder there are many when type by the solid if desired mixed
101 storages, can also be stored by multiple solid feeders 101.Fluid Supplying apparatus 102 is used to storing and supplying liquid,
Wherein, the liquid includes the case where referring to that suspension, the suspension refer to liquid and the mixed liquid of solid.Other
In embodiment, fluid Supplying apparatus 102 can be multiple, a part of fluid Supplying apparatus supply liquid, a part of liquid supply
Device becomes the supply of the suspension after suspension for liquid.It in all embodiments of the invention, include outstanding with liquid
The case where supernatant liquid, is illustrated.For example, equipment 10 is started to work a period of time, by liquid and solid in rotor chamber 106
It is mixed into suspension, rotor chamber 106 is then discharged by the outlet 1064 of rotor chamber 106, if the suspension is not yet up to standard
Or equipment 10 need to carry out circulation mixing to solid and liquid, then outlet 1064 can connect aforesaid liquid feedway 102,
Suspension is supplied again by fluid Supplying apparatus 102 to liquid distributor chamber.
Liquid distributor chamber 103 is for the liquid that fluid Supplying apparatus 102 is supplied to be allocated with predetermined amount of flow.At this
It is described liquid to be allocated liquid with predetermined amount of flow the fluid flow in liquid distributor chamber 103 be made to fill in embodiment
Foot, and liquid is evenly distributed in liquid distributor chamber 103, to guarantee that liquid does not generate cavitation erosion in liquid distributor chamber 103
Destruction, cavitation will not occur in the liquid in liquid distributor chamber 103, also real so that equipment 10 be avoided to be damaged
Existing liquid is not in hole when entering mixing chamber 105 and solid contact, avoids solid from entering liquid hole and forms agglomeration, causes
Equipment blocking.For example, it can be adjusted by 1031 quantity of entry nozzle of liquid distributor chamber 103, fluid Supplying apparatus 102
The revolving speed of the liquid delivery pump (omission is not drawn into) of connection changes or both the distribution that Binding change realizes fluid flow respectively.
For example, by increasing the quantity of entry nozzle 1031, realizing the flow abundance after liquid enters liquid distributor chamber 103 and dividing
Cloth is uniform；In addition, control injection pressure is realized in liquid distributor chamber 103 by increasing liquid delivery pump to entry nozzle 1031
It the flow abundance of liquid and is evenly distributed.Of course, it is possible to the flow direction of liquid is controlled by adjusting the angle of entry nozzle 1031,
Realize the control of fluid flow.In addition, Fig. 5 also give it is a kind of using porous ring 1032 realize fluid flow control by the way of,
The porous ring 1032 is located in liquid distributor chamber 103, under entry nozzle 1031, has in the porous ring 1032 multiple
Being evenly distributed and flow abundance for liquid may be implemented after flowing through open-work in hole, liquid.
The solid is transported to mixed by Solid Conveying and Melting room 104 by screw rod drawing-in device 1041 from solid feeder 101
Close room 105.Screw rod drawing-in device 1041 solid is continuous, uniform can be sent into mixing chamber 105, to avoid solid and liquid
There is the excessive or very few situation of solid, solid excessively then be easy to cause solid block when mixing chamber 105 contacts in body
The case where with blocking, the problem of also bringing solid and liquid to infiltrate and uniformly mix difficulty increase；Solid is very few, and it will cause same
A collection of all solids and the uniformly mixed difficulty of liquid are big, need to increase circulation mixing number and realize with a batch all solids and liquid
Uniform mixing.No. 851 patents and No. 607 patents are all continuous, uniform for giving liquid mixing without control solid, this two
Solid glut or very few situation can all occur in patent.
For example, when the second ball valve is opened in No. 851 patents, the bulk solids in medial compartment are emptied into solid confession
To in room, whole bulk solids reach solid supply chamber simultaneously and crushing vane are made to be difficult to crush bulk solids, and then may
Cause excessive bulk solids to be sent into mixing chamber to contact with liquid, forms agglomerate or result in blockage, in addition, the swabbing effect of discharge chambe
The problem can also be aggravated to the suction of bulk solids；At the same time, in No. 851 patent requirements bulk solids in solid supply chamber
Reach in accelerating chamber liquid, suspension three's synchronous rotary is realized under the requirement of laminar flow effect in discharge chambe, work as whole
When bulk solids reach solid supply chamber simultaneously, bulk solids can be made, which to reach three's synchronous rotary, becomes more difficult, even if
It realizes that synchronous rotary is also required to complicated structure and intensity, increases a large amount of energy consumption, aggravate equipment attrition.And bulk solids reach
Synchronous rotary to suspension is very difficult, if having reached the synchronous rotary with suspension, the pine rotated under this speed
Solid is dissipated since centrifugal force all concentrates on the bucket wall of solid supply chamber, agglomeration and blocking is easy to cause after undue concentration, especially
It is that agglomeration or blocking or powder bridging problem are formed on the bucket wall of solid supply chamber Yu mixing chamber junction, if solid is
Simple titanium white either carbon dust, the bridge formation problem of powder further will acutely amplify, and be easy to formation in a device
The bridging of powder.And since mixing apparatus is the equipment to run at high speed, the factors such as mechanical strength is limited to, cannot constantly be expanded
The quantity in the space of discharge chambe, solid and liquid that mixing apparatus is handled within the unit time is very big, with a batch of solid and
Liquid, which needs to recycle mixing, can be only achieved uniformly, and No. 851 patents exist with a batch of previous work stage, bulk solids mistake
Enter mixing chamber to infiltrate and mix with liquid more, needs to increase the leaching that cycle-index is just able to achieve the solid and liquid of same batch
Profit and uniformly mixing.In addition, No. 851 patents do not control the flow of liquid, when fluid flow is uneven or flow not
When sufficient, rotation of the liquid in accelerating chamber will aggravate the cavitation erosion generated to accelerating chamber, under such circumstances, also shadow certainly
The infiltration of bulk solids and liquid and evenly dispersed is rung.
It agglomerates or blocks in addition, No. 607 patents exist mix with powder excessive or very few in No. 851 patents with liquid
Same problem.Specifically, No. 607 patents are not carried out the requirement of laminar flow in No. 851, No. 607 patents are rotated by rotor to be produced
Raw swabbing effect, the fluid flow that will lead to conveying to the conveying of liquid on axially and radially is unstable, and liquid is easy shape
At hole, while powder is also drawn into process chamber by the swabbing effect that rotor generates and infiltrates and mix with liquid, into processing
The fluid flow of room is unstable and powder inlet is unstable is easy to cause to agglomerate or blocks or mix non-uniform
Problem.In addition, under such circumstances, the unstable liquid that equally also will appear of fluid flow is to the cavitation erosion of equipment, in turn
It is further exacerbated by the increase in liquid hollow cave, thus the problems such as exacerbating agglomeration or blocking.
In the embodiment shown in fig. 1, the present invention realizes that axial conveying is solid using 1041 conveying solid substance of screw rod drawing-in device
Body will not be generated and be rotated with the solid of liquid synchronous rotary；In the embodiment depicted in figure 2, the screw rod feeding dress that the present invention uses
It sets 1041 to be made of conveying axis 108 and conveying axle thread 1081, the solid of conveying will not be with liquid synchronous rotary；Certainly, if
The screw rod drawing-in device 1041 in screw rod drawing-in device 1041 and Fig. 2 that main shaft 107 and spindle thread 1071 are constituted in Fig. 1 is simultaneously
Exist in apparatus 10, the solid and liquid synchronous rotary of conveying will not be generated.The present invention passes through screw rod drawing-in device 1041
Conveying to solid, realize solid not with liquid synchronous rotary, on the one hand can to avoid rotor chamber 106 swabbing effect to solid
Suction generate it is unstable, on the one hand can it is continuous, Solid Conveying and Melting uniformly entered into mixing chamber 105 mixed with liquid, reality
Now with batch of solid and liquid infiltration and mixing it is uniform, reduce the cycle-index of mixing.
It is significant to note that the main shaft 107 and conveying axis 108 of Fig. 1 and Fig. 2 screw rod drawing-in device 1041 are in the accompanying drawings
It is shown as the form of cylindrical body, but in the present invention, it should not be cylindrical by 1041 restrictive interpretation of screw rod drawing-in device
The screw rod of formula more should in no way limit as a screw rod.For example, it is adopted referring to the screw rod drawing-in device 1041 in Fig. 3 and Fig. 4
It is more than two round wheel drive Flat conveyors, wherein point several regions on conveyer belt, subregion on conveyer belt can be with
Realize the uniform continuous conveying of solid.Certainly, even if screw rod drawing-in device 1041 in Fig. 3 and Fig. 4 is known as chain conveying
Band, chain plate conveyor belt or belt conveyor, the grade conveyer belts also belong in the range of screw rod drawing-in device 1041 of the present invention.
In addition, the present invention is supplied using multiple solids in the case where needing to infiltrate and mix there are a plurality of types of solids
