[0040] Please refer to Figures 1 to 9 The utility model provides a slurry stirrer which can break up agglomerates, in order to better understand the above technical solution, the above technical solution will be explained in detail below in combination with the drawings and specific embodiments of the specification.
[0041] In one embodiment of the utility model technical scheme:
[0042] It comprises a stirring shaft 1, a feeding disc 2, a stirring paddle 3 and a stirring tank 4;
[0043] The stirring tank 4 is a closed tank body with an open top, and a motor 11 is arranged at the bottom of the stirring tank 4,
[0044] The stirring shaft 1 is a straight rod, and is arranged vertically inside the stirring tank 4; the lower end of the stirring shaft 1 extends below the stirring tank 4 and is connected to the driving shaft of the motor 11; the stirring shaft 1 penetrates the bottom of the stirring tank 4 through a mechanical seal, so as to ensure the sealing of the stirring tank 4;
[0045] The feeding disc 2 is a disc-shaped material groove with a closed periphery and an open top; the bottom of the feeding disc 2 is a flat mesh plate; the feeding disc 2 is detachably butted to the upper end of the stirring shaft 1; and the feeding disc 2 rotates synchronously with the stirring shaft 1;
[0046] A butt joint rod 21 is protruded downward at the center of the feeding disc 2, and the butt joint rod 21 is fixedly connected to the feeding disc 2;
[0047] The butt joint rod 21 is a straight rod with splines; a butt joint hole 12 is recessed downward at the center of the top end of the stirring shaft 1; the butt joint rod 21 is detachably inserted into the butt joint hole 12; and the butt joint hole 12 and the butt joint rod 21 are driven by splines;
[0048] The butt joint rod 21 and the butt joint rod 21 are in transition fit;
[0049] The vertical axes of the butt joint hole 12 and the butt joint rod 21 coincide. With such a structure, the feeding disc 2 can be conveniently detached for feeding dry materials into the stirring tank 4, and the feeding disc 2 can be reinstalled for butt joint when water or solvent is fed, so that the feeding disc 2 rotates synchronously with the stirring shaft 1, thereby breaking up and feeding water into the stirring tank 4, so that the water and the dry materials are more quickly stirred and dispersed.
[0050] The stirring paddle 3 is a long rod, and multiple stirring paddles 3 are horizontally extended on the vertical side wall of the stirring shaft 1, are uniformly arranged around the stirring shaft 1, are not on the same horizontal plane, and are not in contact with each other; the projection angle of adjacent stirring paddles 3 on the same horizontal plane is the same, and the projection angle is b; the stirring paddles 3 divide the whole circle into different angles, and the device is provided with three stirring paddles 3, and the interval angle between the three stirring paddles 3 is 120°.
[0051] The height difference between the stirring paddles 3 is also the same, that is, the height interval between the upper, middle and lower parts of the stirring paddle 3 is the same.
[0052] Each stirring paddle 3 is provided with a first turbulence block 31, a second turbulence block 32 and a third turbulence block 33; the first turbulence block 31 and the third turbulence block 33 are symmetrically arranged on the left and right sides of the second turbulence block 32.
[0053] The second turbulence block 32 is horizontally arranged, and the first turbulence block 31 and the third turbulence block 33 are inclinedly arranged, and the relative side of the first turbulence block 31 and the third turbulence block 33 is low, and the side away from it is high.
[0054] The inclination angle a of the first turbulence block 31 and the third turbulence block 33 is 15°, the second turbulence block 32 extends forward on the stirring paddle 3, and one end of the second turbulence block 32 extending forward is inclined downward, and the included angle c between the second turbulence block 32 and the stirring paddle 3 is 60°; and the front end indicated by the second turbulence block 32 is the forward direction of rotation in the stirring direction, that is, the direction of stirring the mixture, as shown in Figure 9 The lower side of the second turbulence block 32 is the front end.
[0055] Such inclined turbulence blocks can move the mixture close to the stirring shaft 1 and the inner wall of the stirring tank 4 to the second turbulence block 32 through the first turbulence block 31 and the third turbulence block 33, thereby concentrating the mixture on the same horizontal plane during the rotation and stirring of the stirring paddle 3, and dispersing the mixture in the original inner and outer layers, realizing the mixing and stirring in the inner and outer directions, avoiding the solidification of the layers, and the height positions of each stirring paddle 3 are different, so that the mixture can be stirred at different heights to avoid the solidification of the layer structure, so that the mixture in the upper, middle and lower layers can also be uniformly stirred and dispersed, effectively reducing the number of concrete and sand lumps. The first turbulence block 31, the second turbulence block 32 and the third turbulence block 33 are full of protruding spikes, which can quickly decompose and disperse the agglomerated slurry, so that the components are uniformly stirred.
[0056] The vertical axes of the stirring shaft 1, the feeding disc 2 and the stirring tank 4 coincide.
[0057] It should be noted that:
[0058] 1. When mixing concrete mortar, poor water flow makes it difficult to disperse evenly, leading to severe clumping within the mortar. These clumps are of varying sizes and numerous, posing a challenge to vertical mixers. This results in uneven mixing, requiring manual breaking up before use. The lack of moisture within the clumps prevents the various components from dissolving and mixing. This device uses three different baffles to agitate the clumps. The spikes on these baffles break down the surface tension of the clumps, reducing clumping. 2. Existing vertical mixers typically have the mixing blades positioned near the bottom and on the same plane. This mixing method... The mixture inside the mixer, under the agitation of a fixed speed, fixed blade shape, and fixed number of mixing blades, can easily form a fixed flow state, causing the concrete to separate into upper and lower layers, and inner and outer layers, making it difficult to achieve sufficient mixing. This device uses three different mixing blades 3 to mix at different positions, preventing the concrete from separating into upper and lower layers, and instead achieving uniform mixing from top to bottom, so that the concrete is tumbled up and down in the mixing tank 4. In addition, multiple turbulence blocks are added. The first turbulence block 31 on the same mixing blade 3 agitates and guides the flow from the inside out, while the second turbulence block 33 pushes the concrete back from the outside in, preventing the concrete from forming an inner and outer layer state, and instead causing both the inside and outside to flow towards the second turbulence block 32, resulting in a more dispersed and uniform mixture.
[0059] When using this invention, dry materials are put into the mixing tank 4, then an appropriate amount of water is poured in, and the feeding plate 2 is placed on the mixing shaft 1 so that the mixing shaft 1 rotates together with the feeding plate 2.
[0060] When adding water, do not add too much at the beginning, but add water in small amounts multiple times. Then turn on the motor 11. The stirring shaft 1 carries the stirring paddle 3 and the feeding plate 2 to rotate together. Continue to add water during the stirring process. The water will flow into the mixing tank 4 through the mesh at the bottom of the feeding plate 2. The water will also be dispersed and flowed by the rotating feeding plate 2, which can mix with the floating materials more quickly and stir the mixture more evenly.
[0061] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
