[0004] In the process of implementing the present application, the inventor found that at least the following problems exist in this technology: Since both the stirring blade and the magnetic stirrer perform horizontal stirring, part of the materials in the slurry are prone to precipitation, resulting in a high concentration of the slurry at the bottom of the stirring cylinder, making the various materials in the slurry unevenly mixed and affecting the quality of slurry preparation. Summary of the Utility Model

[0005] In order to facilitate the uniform mixing of the slurry and improve the quality of slurry preparation, the present application provides a mixing device for improving the batching efficiency of slurry production.

[0006] The mixing device for improving the batching efficiency of slurry production provided by the present application adopts the following technical solutions:

[0007] A mixing device for improving the batching efficiency of slurry production includes a frame, a cylinder body is fixedly arranged on the frame, a discharge pipe is communicated at the bottom of the cylinder body, a cylinder cover is arranged on the top of the cylinder body, a feed pipe penetrates through the cylinder cover, a circulating inlet pipe penetrates through one side of the cylinder body near the top, a circulating outlet pipe penetrates through one side of the cylinder body near the bottom, a circulating pump is communicated between the circulating inlet pipe and the circulating outlet pipe, a set of dispersion components are arranged in the cylinder body, the dispersion components are used to disperse the slurry, and a stirring component is arranged between the dispersion components, and the stirring component is used to stir the slurry.

[0008] By adopting the above technical solution, when the raw materials are placed in the cylinder body for mixing, the raw materials that precipitate and form lumps at the bottom of the cylinder body collide with the dispersion assembly near the bottom of the cylinder body, causing the lumped raw materials to break up. Then, the slurry in the lower part of the cylinder body is pumped into the upper part of the cylinder body through the circulation outlet pipe and the circulation inlet pipe by the circulation pump, and is mixed with the slurry in the upper part of the cylinder body again, achieving the effect of the slurry flowing up and down in the cylinder body. The slurry located in the upper part of the cylinder body is dispersed by the dispersion assembly near the top of the cylinder body, so that the solid raw materials in the slurry are evenly distributed in the liquid raw materials. The slurry located in the middle part of the cylinder body is stirred by the stirring assembly, so that the solid raw materials and the liquid raw materials are mixed. Through the circulation pump, the dispersion assembly and the stirring assembly, the slurry flows in the cylinder body in the height direction, and further makes the various materials in the slurry mix evenly, making it difficult for dead corners to exist inside the cylinder body, thus facilitating the uniform mixing of the slurry and improving the quality of slurry preparation.

[0009] Preferably, a driving motor is fixedly arranged at the bottom of the cylinder body. The output shaft of the driving motor penetrates the bottom wall of the cylinder body, and a driving main shaft is fixedly arranged on the output shaft of the driving motor. Both the dispersion assembly and the stirring assembly are connected to the driving main shaft.

[0010] By adopting the above technical solution, when the driving motor is started, it drives the driving main shaft to rotate, and the rotation of the driving main shaft makes the dispersion assembly and the stirring assembly act.

[0011] Preferably, one of the dispersion assemblies is directly above the other dispersion assembly. The dispersion assembly is located below the circulation inlet pipe and above the circulation outlet pipe. The dispersion assembly includes a set of dispersion discs, and the dispersion discs are connected between the driving main shaft and the inner wall of the cylinder body, and one of the dispersion discs is directly above the other dispersion disc.

[0012] By adopting the above technical solution, the dispersion discs form multi-stage dispersion of the slurry, thereby improving the dispersion effect of the slurry, facilitating the uniform mixing of the slurry, and improving the quality of slurry preparation.

[0013] Preferably, the dispersion disc includes a dispersion ring sleeve, a dispersion bottom plate and a number of dispersion lower teeth. The bottom ends of the dispersion lower teeth are fixedly connected to the top of the dispersion bottom plate. The dispersion bottom plate is sleeved on the driving main shaft and is fixedly connected to the driving main shaft. The dispersion ring sleeve is sleeved outside the dispersion bottom plate, and there is a discharge channel between the dispersion ring sleeve and the dispersion bottom plate. The outer wall of the dispersion ring sleeve is in mutual fit with the inner wall of the cylinder body, and the outer wall of the dispersion ring sleeve is fixedly connected to the inner wall of the cylinder body.

[0014] By adopting the above technical solution, the rotation of the driving main shaft drives the dispersion bottom plate to rotate, and the rotation of the dispersion bottom plate drives the dispersion lower teeth to move. Furthermore, the dispersion lower teeth move relative to the slurry, achieving the effects of friction, impact, extrusion, shearing, etc. between the dispersion lower teeth and the slurry, facilitating the uniform mixing of the slurry, and improving the quality of slurry preparation.

[0015] Preferably, the dispersion assembly further includes a dispersion top plate and a plurality of upper dispersion teeth. A dispersion inlet is formed in the dispersion top plate. The dispersion top plate is fixedly arranged at the top of the dispersion ring sleeve. The dispersion top plate is located above the dispersion bottom plate. The top ends of the upper dispersion teeth are fixedly connected to the bottom of the dispersion top plate. There is a gap between the bottom ends of the upper dispersion teeth and the top of the dispersion bottom plate. There is a gap between the top ends of the lower dispersion teeth and the bottom of the dispersion top plate. The upper dispersion teeth are located between adjacent lower dispersion teeth, and the lower dispersion teeth are located between adjacent upper dispersion teeth.

[0016] By adopting the above technical solution, when the lower dispersion teeth move, relative movement occurs between the lower dispersion teeth and the upper dispersion teeth. Then, the slurry undergoes friction, impact, extrusion, shearing and other actions between the lower dispersion teeth and the upper dispersion teeth, facilitating the uniform mixing of the slurry and improving the quality of slurry preparation.

[0017] Preferably, a diversion groove is formed at the top of the dispersion top plate, and the diversion groove is communicated with the dispersion inlet.

[0018] By adopting the above technical solution, when the slurry moves downward in the cylinder body, the diversion groove facilitates the flow of the slurry to the dispersion inlet, thereby improving the mixing efficiency of the slurry.

[0019] Preferably, the stirring assembly includes a stirring frame and a plurality of spiral rods. The stirring frame is fixedly arranged on the driving main shaft, and the spiral rods are rotatably arranged on the stirring frame.

[0020] By adopting the above technical solution, the rotation of the driving main shaft drives the rotation of the stirring frame, and the rotation of the stirring frame drives the movement of the spiral rods. Then, the spiral rods perform preliminary stirring on the slurry, facilitating the uniform mixing of the slurry and improving the quality of slurry preparation.

[0021] Preferably, a closed housing is arranged between the spiral rods and the stirring frame. A stirring motor is fixedly arranged in the closed housing. The output shaft of the stirring motor penetrates through the closed housing, and the output shaft of the stirring motor is fixedly connected to the spiral rods.

[0022] By adopting the above technical solution, when the driving main shaft rotates, the stirring motor drives the spiral rods to rotate, and the spiral rods perform secondary stirring on the slurry, making it difficult for dead corners to exist inside the cylinder, thereby facilitating the uniform mixing of the slurry and improving the quality of slurry preparation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

Detailed Description of the Embodiment

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 drawings.

[0032] An embodiment of the present application discloses a mixing device for improving the production batching efficiency of slurry. Refer to Figure 1, including a frame 1, on which a cylinder block 2 is installed. A discharge pipe 21 is connected to the bottom of the cylinder block 2. A cylinder head 3 is installed on the top of the cylinder block 2, and a feed pipe 31 penetrates through the cylinder head 3. The inside of the cylinder block 2 is divided into three regions: upper, middle, and lower according to height. A circulation inlet pipe 41 penetrates through one side of the cylinder block 2 near the top, and the circulation inlet pipe 41 is connected to the upper region inside the cylinder block 2; a circulation outlet pipe 42 penetrates through one side of the cylinder block 2 near the bottom, and the circulation outlet pipe 42 is connected to the lower region inside the cylinder block 2. A circulation pump 4 is installed between the circulation inlet pipe 41 and the circulation outlet pipe 42. The input end of the circulation pump 4 is connected to the circulation outlet pipe 42, and the output end of the circulation pump 4 is connected to the circulation inlet pipe 41. A set of dispersion components 6 is installed inside the cylinder block 2. The dispersion components 6 are used to disperse the slurry. One dispersion component 6 is located in the upper region of the steel, and the other dispersion component 6 is located in the lower region of the cylinder block 2. A stirring component 7 is installed between the dispersion components 6. The stirring component 7 is located in the middle region of the cylinder block 2, and the stirring component 7 is used to stir the slurry. A driving main shaft 51 is commonly installed on the dispersion components 6 and the stirring component 7. The driving main shaft 51 is rotatably installed inside the cylinder block 2. The bottom wall of the cylinder block 2 is welded with a driving motor 5. The output shaft of the driving motor 5 penetrates through the bottom wall of the cylinder block 2, and the output shaft of the driving motor 5 is welded to the driving main shaft 51. When the raw materials are placed inside the cylinder block 2 for mixing, both the driving motor 5 and the circulation pump 4 are started. The driving motor 5 drives the dispersion components 6 and the stirring component 7 to act through the driving main shaft 51. The circulation pump 4 pumps the slurry in the lower region of the cylinder block 2 from the circulation outlet pipe 42 and the circulation inlet pipe 41 into the upper region of the cylinder block 2, achieving the effect of the slurry flowing up and down inside the cylinder block 2. During the process of the slurry flowing and stirring inside the cylinder block 2, the raw materials that precipitate and form lumps at the bottom of the cylinder block 2 collide with the dispersion component 6 near the lower region of the cylinder block 2, causing the raw materials that form lumps to break up. Then, the slurry in the lower region of the cylinder block 2 is pumped into the upper part of the cylinder block 2 and mixed with the slurry in the upper part of the cylinder block 2 again. The dispersion component 6 located in the upper region of the cylinder block 2 evenly distributes the solid raw materials in the slurry into the liquid raw materials. Then, the slurry in the upper region of the cylinder block 2 flows to the middle region of the cylinder block 2. The stirring component 7 stirs the slurry in the middle region of the cylinder block 2 to mix the solid raw materials and the liquid raw materials. After being stirred, the slurry in the middle region of the cylinder block 2 flows to the lower region of the cylinder block 2. This process is repeated, enabling the slurry to be circulated for dispersion and stirring, making it difficult for dead corners to exist inside the cylinder block 2, thereby making the materials in the slurry mix evenly, facilitating the uniform mixing of the slurry, and improving the quality of slurry preparation.

[0033] In order to perform multi-stage dispersion on the slurry, refer to Figure 1 and Figure 2, the dispersion component 6 is located below the circulation inlet pipe 41 and above the circulation outlet pipe 42, and one dispersion component 6 is directly above another dispersion component 6. The dispersion component 6 includes a set of dispersion discs 61, and the dispersion discs 61 are connected between the driving main shaft 51 and the inner wall of the cylinder block 2, and one dispersion disc 61 is directly above another dispersion disc 61. The dispersion disc 61 includes a dispersion ring sleeve 611, a dispersion bottom plate 612, a number of dispersion lower teeth 613, a dispersion top plate 614 and a number of dispersion upper teeth 615. The dispersion ring sleeve 611 is fixedly installed in the cylinder block 2, and the outer wall of the dispersion ring sleeve 611 is in close contact with the inner wall of the cylinder block 2. The dispersion top plate 614 is fixedly installed on the top of the dispersion ring sleeve 611, and a dispersion inlet 63 is provided on the dispersion top plate 614. The dispersion bottom plate 612 is fixedly installed on the driving main shaft 51, and the driving main shaft 51 penetrates through the center of the dispersion bottom plate 612. The dispersion ring sleeve 611 is sleeved outside the dispersion bottom plate 612, and there is a discharge channel 62 between the dispersion ring sleeve 611 and the dispersion bottom plate 612. The dispersion top plate 614 is located above the dispersion bottom plate 612. The top end of the dispersion upper tooth 615 is welded to the bottom of the dispersion top plate 614, and there is a gap between the bottom end of the dispersion upper tooth 615 and the top of the dispersion bottom plate 612. There is a gap between the top end of the dispersion lower tooth 613 and the bottom of the dispersion top plate 614, and the bottom end of the dispersion lower tooth 613 is welded to the top of the dispersion bottom plate 612. The dispersion upper teeth 615 are located between adjacent dispersion lower teeth 613, and the dispersion lower teeth 613 are located between adjacent dispersion upper teeth 615. The rotation of the driving main shaft 51 drives the dispersion bottom plate 612 to rotate, the rotation of the dispersion bottom plate 612 drives the dispersion lower teeth 613 to move, the dispersion lower teeth 613 and the dispersion upper teeth 615 move relatively, and the slurry undergoes friction, impact, extrusion, shearing and other effects between the dispersion lower teeth 613 and the dispersion upper teeth 615. When the slurry moves downward in the cylinder block 2, the slurry passes through four dispersion discs 61 in sequence. The multiple arranged dispersion discs 61 form multi-stage dispersion of the slurry, thereby improving the dispersion effect of the slurry, facilitating the uniform mixing of the slurry, and improving the quality of slurry preparation.

[0034] Reference Figure 2 , a diversion groove 64 is provided on the top of the dispersion top plate 614, and the diversion groove 64 is communicated with the dispersion inlet 63. When the slurry moves downward in the cylinder block 2, the diversion groove 64 facilitates the flow of the slurry to the dispersion inlet 63, thereby improving the mixing efficiency of the slurry.

[0035] In order to perform multi-stage stirring on the slurry, refer to Figure 1 and Figure 3, the stirring assembly 7 includes a stirring frame 71 and a plurality of screw rods 72. The stirring frame 71 is fixedly installed on the driving main shaft 51, and a closed housing 8 is installed between the screw rod 72 and the stirring frame 71. A stirring motor 81 is installed inside the closed housing 8. The output shaft of the stirring motor 81 penetrates the closed housing 8, and the output shaft of the stirring motor 81 is welded to the screw rod 72. The rotation of the driving main shaft 51 drives the rotation of the stirring frame 71, and the rotation of the stirring frame 71 drives the screw rod 72 to move, so that the screw rod 72 performs preliminary stirring on the slurry. At the same time, the stirring motor 81 drives the screw rod 72 to rotate, and the screw rod 72 performs secondary stirring on the slurry, so as to facilitate the uniform mixing of the slurry.

[0036] The implementation principle of a mixing device for improving the production batching efficiency of slurry in an embodiment of the present application is as follows: When the raw materials are placed in the cylinder body 2 for mixing, the driving motor 5, the stirring motor 81, and the circulation pump 4 are all started. The driving motor 5 and the stirring motor 81 perform multi-stage dispersion and multi-stage stirring on the slurry. The circulation pump 4 pumps the slurry in the lower region of the cylinder body 2 into the upper region of the cylinder body 2 through the circulation outlet pipe 42 and the circulation inlet pipe 41, so that the slurry in the cylinder body 2 flows up and down. During the process of the slurry flowing and mixing in the cylinder body 2, the dispersion disc 61 in the lower region of the cylinder body 2 breaks up the agglomerated raw materials, and the broken raw materials are pumped into the upper part of the cylinder body 2 along with the slurry in the lower region of the cylinder body 2 and are mixed with the slurry in the upper part of the cylinder body 2 again. The dispersion disc 61 in the upper region of the cylinder body 2 evenly distributes the solid raw materials in the slurry into the liquid raw materials, and then the slurry in the upper region of the cylinder body 2 flows to the middle region of the cylinder body 2. The screw rod 72 stirs the slurry in the middle region of the cylinder body 2 to mix the solid raw materials and the liquid raw materials, and the slurry in the middle region of the cylinder body 2 flows to the lower region of the cylinder body 2 after stirring. This process is repeated, so that the slurry is circulated for dispersion and stirring, and there are no dead corners inside the cylinder body 2, so that the materials in the slurry are mixed evenly, which is convenient for the uniform mixing of the slurry and improves the quality of slurry preparation.

[0037] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
