[0032] The connecting assembly includes a driving unit and a rotating shaft 101; the driving unit is arranged on the upper side of the mixing barrel 1; the rotating shaft 101 is connected to the lower side of the driving unit; the lower end of the rotating shaft 101 is fixedly connected to the stirring paddle 3; the rotating shaft 101 and the stirring paddle 3 are driven to rotate by the driving unit.

[0033] The driving unit includes a motor 102 ; the motor 102 is fixedly connected to the upper side of the mixing barrel 1 ; and the output end of the motor 102 is fixedly connected to the rotating shaft 101 .

[0034] The drainage assembly includes a drainage plate 201 and a drainage cover 202; the outer side of the stirring paddle 3 is fixedly connected with the drainage plates 201 in a circular array; the inclination direction of each drainage plate 201 is opposite to the inclination direction of each stirring blade on the stirring paddle 3; and a drainage cover 202 is fixedly connected to the outer sides of several drainage plates 201.

[0035] The through groove 4001 on each diffuser 4 has a tapered structure from the liquid inlet to the liquid outlet; this helps to speed up the flow rate of the liquid raw material when passing through the through groove 4001, enhance the impact effect of the mixed raw material on the powder raw material accumulated at the liquid outlet of the through groove 4001, prevent the powder raw material from accumulating between two adjacent diffusers 4, and improve the mixing effect of the liquid raw material and the powder raw material.

[0037] Each swing plate 5 is provided with a plurality of crushing parts 5001 .

[0038] The specific process of anti-accumulation of the utility model is as follows:

[0039] Before stirring the raw materials, the staff first adds the liquid raw material into the stirring barrel 1 through the feed port 1001, and then controls the motor 102 to drive the rotating shaft 101 to rotate, so that the stirring paddle 3 stirs the liquid raw material, and then the liquid raw material forms a vortex flow. Then the staff adds the powder raw material into the stirring barrel 1 through the feed port 1001 to mix with the liquid raw material. When the powder raw material passes through the stirring paddle 3 for stirring and mixing, the stirring paddle 3 that descends from the outside to the middle guides the powder raw material to the lower part of the outside of the stirring paddle 3 to prevent the powder raw material from accumulating in the middle of the vortex flow formed by the liquid raw material. After the powder raw material passes through the stirring paddle 3 from top to bottom, the powder raw material is guided upward into the inside of the drainage cover 202 by the drainage plate 201 that is opposite to the inclination direction of the stirring blade on the stirring paddle 3, and then sprayed out from above the stirring paddle 3, so that the powder raw material forms a turbulent flow on the outside of the stirring paddle 3, and the powder raw material is prevented from being guided to the lower part of the outside of the stirring paddle 3 and then accumulated on the bottom edge of the stirring barrel 1, thereby improving the mixing effect of the liquid raw material and the powder raw material.

[0040] When the raw materials are stirred and mixed, the powder raw materials deposited on the bottom of the stirring barrel 1 come into contact with the diffuser 4. The diffuser 4 is lowered from the middle of the stirring barrel 1 to the outside of the stirring barrel 1, and the middle of the upper surface is lowered toward the liquid inlet and the liquid outlet at both ends of the through groove 4001. The powder raw materials accumulated in the middle of the stirring barrel 1 are guided to the side wall of the stirring barrel 1 to prevent the powder raw materials from accumulating at the bottom of the stirring barrel 1, thereby further improving the mixing effect of the liquid raw materials and the powder raw materials. When the powder raw materials pass through the diffuser 4 and are guided to the side wall of the stirring barrel 1 by the diffuser 4, part of the powder raw materials accumulate between two adjacent diffusers 4. The through groove 4001, which has a constricted structure from the liquid inlet to the liquid outlet, accelerates the flow rate of the liquid raw materials when passing through the through groove 4001, thereby enhancing the mixing The impact effect of the combined raw materials on the powder raw materials accumulated at the liquid outlet of the through slot 4001 prevents the powder raw materials from accumulating between two adjacent diffusers 4, further improving the mixing effect of the liquid raw materials and the powder raw materials. At the same time, the agglomerated powder raw materials flowing to the liquid inlet of the through slot 4001 are intercepted and guided upward by the filter screen 4002 to prevent the agglomerated powder raw materials from clogging the through slot 4001. When the liquid raw materials pass through the through slot 4001, the pendulum 5 is driven by the liquid flow to swing, and the agglomerated powder raw materials accumulated at the liquid outlet of the through slot 4001 are broken by the breaking part 5001 on the pendulum 5, so that the powder raw materials are fully mixed with the liquid raw materials, further improving the mixing effect of the liquid raw materials and the powder raw materials.

[0041] Example 2

[0042] On the basis of Example 1, Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the guide system includes a fixed ring 301 and guide plates 302; the fixed ring 301 is fixedly connected to the inner bottom of the mixing barrel 1; a plurality of guide plates 302 are fixedly connected to the inner ring surface of the fixed ring 301; each guide plate 302 is inclined along the rotation direction of the mixed raw material.

[0043] like Fig. 9 As shown, the upper surface of the fixing ring 301 is arranged to be inclined toward the middle of the lower side of the fixing ring 301, which is beneficial to prevent the powder raw material from accumulating on the upper surface of the fixing ring 301 and enhance the mixing effect of the liquid raw material and the powder raw material.

[0044] The flow guide system further includes a guide block 303 ; a guide block 303 is fixedly connected between each two adjacent flow guide plates 302 ; and from bottom to top as a reference, each guide block 303 is arranged to be inclined toward the middle of the mixing barrel 1 .

[0045] The specific process of guiding the utility model is as follows:

[0046] When the powder raw material is guided by the stirring paddle 3 to the fixed ring 301 at the bottom edge of the stirring barrel 1, since the upper surface of the fixed ring 301 is set to be inclined toward the middle of the lower side of the fixed ring 301, it is beneficial to prevent the powder raw material from accumulating on the upper surface of the fixed ring 301, thereby enhancing the mixing effect of the liquid raw material and the powder raw material. At the same time, the guide plate 302 is inclined along the rotation direction of the mixed raw material to guide the powder raw material deposited downward upward along the rotation direction of the mixed raw material, thereby preventing the powder raw material from accumulating on the bottom edge of the stirring barrel 1, thereby enhancing the mixing effect of the liquid raw material and the powder raw material. At the same time, the guide block 303 inclined toward the middle of the stirring barrel 1 guides the powder raw material to the middle of the upper side of the fixed ring 301, so that it is offset with the mixed raw material guided by the stirring paddle 3 to the bottom edge of the stirring barrel 1, and the powder raw material guided by the guide block 303 to the stirring paddle 3 is added to the outer side of the stirring paddle 3 to form a tumbling turbulence, so that the powder raw material is fully mixed with the liquid raw material, thereby further improving the mixing effect of the liquid raw material and the powder raw material.
