When the powder-liquid mixer is used, liquid (slurry) to be mixed enters the liquid dispersion area through the liquid inlet, is dispersed by the liquid dispersion device 2 and then enters the powder-liquid mixing area, then powder to be mixed conveyed by the powder conveying device 3 is mixed with the powder by the mixing device 4, and the mixed powder is discharged from the mixing discharge port 11, so that the effect of mixing the liquid to be mixed with the powder to be mixed after being dispersed is achieved, and the technical difficulties of blockage and dispersion contradiction of high-viscosity mixing materials are overcome.

In this embodiment, the liquid dispersing device 2 includes a coarse shearing device 20 and a fine shearing device 21, and the coarse shearing device 20 is used for performing coarse shearing on the liquid to be mixed in the liquid dispersing area; the fine shearing device 21 is used for finely shearing the liquid to be mixed after being sheared by the coarse shearing device 20, so that the liquid to be mixed becomes thin after being subjected to coarse and fine shearing, the flowability of the liquid becomes good, and the liquid to be mixed is mixed with the powder to be mixed, thereby preventing the liquid to be mixed from entering a powder-liquid mixing area and being blocked after being mixed with the powder to be mixed.

In this embodiment, the rough shearing apparatus 20 includes a first dispersing stator 200, the first dispersing stator 200 is fixedly disposed in the liquid dispersing area and located above the liquid inlet, the first dispersing stator 200 is a disc-shaped structure, the outer wall of the first dispersing stator 200 is attached to the inner wall of the main housing 1, the first dispersing stator 200 has a central cavity 2000, the central cavity 2000 is communicated with the liquid inlet, so that the liquid to be mixed entering the liquid dispersing area from the liquid inlet enters the top of the first dispersing stator 200 through the central cavity 2000. The rough shearing device 20 further includes a first dispersing rotor 201, the first dispersing rotor 201 is also in a disc-shaped structure, the first dispersing rotor 201 is rotatably matched with the first dispersing stator 200 and forms a rough shearing flow channel for shearing the liquid to be mixed in the liquid dispersing area, that is, the first dispersing rotor 201 is rotatably disposed in the liquid dispersing area and rotatably matched with the first dispersing stator 200 and forms a rough shearing flow channel for shearing the liquid to be mixed in the liquid dispersing area, the liquid to be mixed enters the rough shearing flow channel from the position of the central cavity 2000, and the liquid (slurry) to be mixed becomes thin under the shearing action force of the rough shearing flow channel.

In this embodiment, a first annular groove 2001 is formed on the first dispersing stator 200, a plurality of first passages 20010 arranged at intervals are formed on one side wall of the first annular groove 2001 along the radial direction, that is, the outer side wall of the first annular groove 2001 is attached to the inner wall of the main housing 1, and the first passages 20010 are arranged on the inner side wall of the first annular groove 2001; a second annular groove 2010 is formed on the first dispersion rotor 201, and the second annular groove 2010 is in rotating fit with the side wall of the first annular groove 2001, where the first channel 20010 is arranged, that is, the second annular groove 2010 is in rotating fit with the inner wall of the first annular groove 2001; a plurality of second channels 20100 which are arranged at intervals and communicated with the first channel 20010 are formed in the two side walls of the second annular groove 2010 along the radial direction, and the second channels 20100 can be staggered with the first channel 20010 to form the rough shearing flow channel. That is, it can be understood that when the liquid to be mixed enters the top of the first dispersion stator 200 from the position of the central cavity 2000, it is forced to pass through the second passage 20100 on the inner wall of the second annular groove 2010, the first passage 20010 and the second passage 20100 on the outer wall of the second annular groove 2010 in sequence under the baffle of the first dispersion rotor 201, and as the first dispersion rotor 201 is rotatable, the first passage 20010 and the second passage 20100 are staggered with each other under the action force of the rotation of the first dispersion rotor 201, thereby achieving the shearing effect.

It should be noted that, since the outer wall of the first dispersing stator 200 is attached and fixed to the inner wall of the main housing 1, that is, the side wall of the first annular groove 2001, on which the first passage 20010 is oppositely disposed, is attached to the inner wall of the main housing 1; of course, the bottom end of the first dispersing stator 200 is a closed structure, and a central cavity 2000 is disposed at the bottom end of the first dispersing stator 200 to limit the liquid to be dispersed from the central cavity 2000 to the upper side of the first dispersing stator 200. On this basis, because the first dispersing rotor 201 is a disc-shaped structure, the top end of the first dispersing rotor 201 is a closed structure, and a gap is reserved between the outer wall of the second annular groove 2010 and the side wall of the first annular groove 2001, which is attached to the inner wall of the main casing 1, so as to limit the liquid to be dispersed, which enters the upper part of the first dispersing stator 200, to be subjected to rough shearing only through the rough shearing flow channel, and enable the liquid subjected to rough shearing to enter the upper part of the first dispersing rotor 201 from the reserved gap. Therefore, in the course of rough shearing, all the liquid (slurry) to be dispersed entering the upper portion of the first dispersing stator 200 from the central cavity 2000 of the first dispersing stator 200 is forced to enter the fine shearing device 21 from the reserved gap after only being roughly sheared through the rough shearing flow channel under the action of the matching structure of the first dispersing stator 200 and the first dispersing rotor 201, and there is no local dead zone where the slurry is not dispersed, that is, there is no partial slurry sheared through the rough shearing flow channel, and partial slurry enters the upper portion of the first dispersing rotor 201 from other positions. In this way, in the process of shearing the liquid (slurry) to be dispersed by the rough shearing device 20, all the liquid (slurry) to be dispersed passes through the rough shearing flow channel for shearing and dispersing at the same flow rate in a narrow path, so that the liquid (slurry) after dispersion has good consistency.

In this embodiment, a first ring member 20011 is further disposed in the first annular groove 2001 along the circumferential direction thereof, a plurality of third channels 200110 which are disposed at intervals and communicated with the second channels 20100 are disposed on the first ring member 20011 along the radial direction thereof, a second ring member 2011 is further disposed on the first dispersing rotor 201 along the circumferential direction thereof, a third annular groove 20110 is formed on one side wall of the second ring member 2011 and one side wall of the second annular groove 2010, that is, the third annular groove 20110 is formed on the outer side wall of the second ring member 2011 and the outer side wall of the second annular groove 2010. The third annular groove 20110 is rotationally matched with the first ring member 20011, a plurality of fourth channels 20111 which are arranged at intervals and communicated with the third channels 200110 are further formed in the second ring member 2011 along the radial direction of the second ring member 2011, and the fourth channels 20111 and the third channels 200110 can be mutually staggered. That is, it can be understood that the liquid to be mixed enters the third passage 200110 and the fourth passage 20111 in sequence after passing through the second passage 20100 on the outer wall of the second annular groove 2010, and in the rotation process of the first dispersing rotor 201, the third passage 200110 and the fourth passage 20111 are staggered with each other, so that the liquid to be mixed is further sheared, the liquid to be mixed is further thinned, and the shearing effect is better. It can be seen that the liquid to be mixed is roughly sheared twice in the liquid dispersion zone by the rough shearing apparatus 20, so that the shearing effect is better.

It should be noted that the structures of the first dispersing stator and the first dispersing rotor are not limited to the structures illustrated in the drawings, but the inventors may change the structures of the first dispersing stator and the first dispersing rotor and combine them to form a rough shear flow channel different from the rough shear flow channel formed by combining the first dispersing stator and the first dispersing rotor in the drawings. Therefore, it is obvious to those skilled in the art that the shear flow path having the same function as the present invention is formed by reasonably changing the structures of the first dispersing stator and the first dispersing rotor according to the present invention, and it is also within the scope of the present invention.

In addition, the inventors can also increase or decrease the number of shear flow channels depending on the characteristics of the liquid (slurry) to be dispersed, such as increasing the number of shear flow channels or decreasing the number of shear flow channels on the basis of the above shear flow channels. For high-viscosity materials, a plurality of shearing flow passages (shearing paths) are designed to shear and shear the slurry to be thinner, so that the flowability of the materials is better; for materials with lower viscosity, the materials can be dispersed and thinned without so many shearing flow passages. Therefore, it is within the scope of the present invention for those skilled in the art to reasonably modify the number of shear channels.

In this embodiment, the fine shearing device 21 includes a second dispersing stator 210 and a second dispersing rotor 211, the second dispersing stator 210 is fixedly disposed on the inner wall of the main housing 1 and located above the coarse shearing device 20, the second dispersing rotor 211 is rotatably disposed in the liquid dispersing area, the second dispersing rotor 211 and the second dispersing stator 210 are rotatably matched to form a fine shearing flow channel for shearing the liquid to be mixed in the liquid dispersing area, that is, the fine shearing flow channel is used for shearing the liquid to be mixed after being sheared by the coarse shearing flow channel.

The structure of the fine shearing apparatus 21 is the same as that of the coarse shearing apparatus 20, but the shearing channel width is smaller than that of the coarse shearing channel, thereby achieving the effect of coarse and fine shearing. Therefore, the structure of the fine shearing apparatus 21 will not be described in detail herein.

In this embodiment, the mixing device 4 includes a mixing rotor 40, the mixing rotor 40 is a disk-shaped structure, the mixing rotor 40 is rotatably disposed in the powder-liquid mixing region, and the mixing rotor 40 is further provided with a dispersion liquid inlet 400 communicated with the liquid dispersion region, so that the liquid to be mixed dispersed by the liquid dispersion device 2 can enter the mixing rotor from the position of the dispersion liquid inlet 400, that is, it can be understood that the liquid enters the liquid dispersion region from the liquid inlet and enters the mixing rotor from the position of the dispersion liquid inlet 400 after being sheared by the coarse and fine shearing device 21.

In this embodiment, the powder conveying device 3 is a powder conveying impeller, and the blades of the powder conveying impeller are of a spatial inclined twisted structure, which can play a role in conveying powder and achieve the effect of preventing liquid from overflowing to the powder channel.

Also can understand, powder delivery impeller is located the top of compounding rotor, the compounding rotor is kept away from the one end of its dispersion import 400 and is provided with a plurality of archs 401 on the surface, protruding 401 sets up along the circumferential direction of compounding rotor, powder delivery impeller and the coaxial setting of compounding rotor, also powder delivery impeller rotates with the compounding rotor simultaneously, in-process when powder delivery impeller and compounding rotor pivoted simultaneously, produce the vacuum between a plurality of archs 401 and the powder delivery impeller that set up along compounding rotor circumference, thereby form foretell liquid runner 5. As can be seen from this, the powder conveying impeller conveys the powder to be mixed into the liquid flow passage 5 of the powder-liquid mixing region, mixes the powder with the liquid to be mixed that has entered the liquid flow passage 5 from the position of the dispersion liquid inlet 400 of the mixing rotor, and discharges the mixed powder through the mixing discharge port 11.

It should be noted that the principle of the liquid flow channel 5 having a negative pressure formed by combining the powder conveying impeller and the mixing rotor is the same as the principle of the negative pressure generated at the inlet of the centrifuge, and the principle will not be described in detail here.

It should be noted that the liquid channel 5 generates negative pressure to facilitate the degassing of the powder and the infiltration of the liquid to be mixed, that is, the mixing area (inside the liquid channel 5) between the powder to be mixed and the liquid to be mixed is in a negative pressure environment, which facilitates the degassing of the powder to be mixed and the infiltration of the liquid to be mixed, so that the effect of mixing the powder to be mixed and the liquid to be mixed in the liquid channel 5 is better.

That is to say, the mixed material dispersing structure can disperse and crush the mixed material in the liquid flow channel 5, so that the mixing effect of the powder to be mixed and the liquid to be mixed is more uniform. In addition, the mounting portion 410 and the guide portion 411 are both annular structures, so that the effect of dispersing the mixture dispersing structure in the liquid flow channel 5 can be better. Specifically, compounding dispersed structure is a plurality of slant slot 4110 along its circumference setting on the guide part 411, when the powder that waits to mix mixes in liquid runner 5 with the liquid that waits to mix, because liquid is at liquid runner 5 internal rotation, the compounding after consequently mixing is cuted under the effect of slant slot 4110 to play the purpose of the meticulous dispersion of cuting of suspension and centrifugal transport thick liquids, and then reach and carry out dispersion and broken effect with the compounding.
