Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Examples

As shown in fig. 1, the superfine powder stirrer comprises a stirring barrel 1 and a stirring shaft 2 extending into the stirring barrel, wherein the top end of the stirring shaft 2 extends out of the stirring barrel 1 and is connected with a motor 3, the lower part of the stirring shaft 2 is axially provided with a plurality of layers of blades 4, a guide cylinder 5 is arranged on the outer cover of the stirring shaft 2, a flow blocking blade 6 is arranged on the inner wall of the guide cylinder 5, the flow blocking blade 6 is arranged with the blades 4 in a staggered manner, a vertical flow blocking sheet 7 is arranged between the inner wall of the stirring barrel 1 and the guide cylinder 5, a discharge hole 8 is arranged at the bottom of the stirring barrel 1, and a valve 9 is arranged on the discharge hole 8.

In the embodiment, superfine aluminum powder in the autoclaved aerated concrete production is stirred and dispersed, wherein the superfine aluminum powder is aluminum powder screened by a negative pressure screen with fineness of 0.075 produced by a certain company, and aluminum powder with smaller fineness is also adopted according to the adjustment of the process. The powder is silver gray powder, is easy to float on the water surface, and is difficult to disperse in water, so that rapid and uniform stirring is required to be realized by a proper stirrer. The stirrer can be used on the ground by arranging supporting feet on the outer wall of the stirring barrel 1.

After the superfine aluminum powder and the water are added into the stirrer, the motor 3 is started to drive the stirring shaft 2 to rotate, and the superfine aluminum powder and the water are dispersed between the blades 4 and the flow blocking blades 6 to form a solution, so that the dispersing effect of the superfine aluminum powder and the water can be enhanced due to the multi-layer and staggered blade structure. In the dispersing process, the solution outside the guide cylinder 5 is further dispersed under the action of the baffle 7, and the solution between the baffle and the guide cylinder enters the guide cylinder 5 for further dispersion. The integral dispersion force is enhanced mainly by adding the blades and the baffle plates, the solution formed after the reaction of the superfine aluminum powder and the water is clear, and the added blades and baffle plates can not increase the load. By the design, the superfine aluminum powder can be completely dispersed within 1-2 minutes.

Specifically, the adjacent two layers of blades 4 have different sizes, and the flow blocking blade 6 is transversely arranged between the adjacent two layers of blades 4. In this embodiment, three layers of blades 4 are axially arranged at the bottom of the stirring shaft 2 at intervals, wherein the size of the blade 4 in the middle layer is larger than that of the upper layer and the lower layer, the size of the flow blocking blade 6 is not excessively large, and the number of each layer of blades 4 and the number of the flow blocking blades 6 can be 3 or staggered. Through the layered dislocation structure, the superfine powder material has good dispersing effect.

Specifically, as shown in fig. 2, the guide cylinder 5 is fixed in the stirring barrel 1 through a supporting seat 51, and may be welded or bolted. The bottom surface of the guide cylinder 5 is spaced from the bottom surface of the stirring barrel 1, and the bottoms of the guide cylinder 5 and the stirring shaft 2 are opposite to the discharge port 8. A communicating channel is formed between the guide cylinder 5 and the stirring shaft 1 and between the baffle plates 7.

Specifically, the baffle 7 is provided with a plurality of baffle plates, and the baffle plates are uniformly fixed on the inner wall of the stirring barrel 1 at intervals to encircle the guide cylinder 5. In this embodiment, 4-6 baffle plates 7 are uniformly distributed at intervals, each baffle plate 7 can be fixed on the inner wall of the stirring barrel 1 through a bracket, and all baffle plates 7 surround the guide cylinder 5.

Specifically, the upper and lower ends of the flow blocking sheet 7 respectively exceed the upper and lower ends of the guide cylinder 5. The solution between the baffle 7 and the guide cylinder 5 enters the guide cylinder 5 again under the action of the baffle 7.

Specifically, the motor 3 is a high-frequency variable-speed motor, a driving wheel 31 is arranged on an output shaft of the motor 3, a driven wheel 21 is arranged at the top end of the stirring shaft 2, and the driving wheel 31 and the driven wheel 21 are connected through a belt 32. The variable-speed high-frequency motor is a common product with a proper model, and the stirring speed of the variable-speed high-frequency motor can be adjusted according to actual needs. The motor 3 is started, and the driving wheel 31 drives the driven wheel 21 to operate through the belt 32, so that the stirring shaft 2 is driven to rotate.

Specifically, the valve 9 is a straight-through butterfly valve, so that dead angles are not formed at the bottom of the stirring barrel 1, and storage of precipitated caking substances is avoided, so that the dispersion quality of superfine powder is improved, high-efficiency dispersion is achieved, and the stirring machine can be applied to dispersion of superfine powder in autoclaved aerated concrete production and other types of superfine powder such as superfine silicate powder.
