Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details.

The first embodiment is as follows:

referring to fig. 1 to 3, a foam concrete mixing apparatus includes a mixing tank 1 and a mixer 2; the stirring tank 1 is provided with a stirring space 10 with a V-shaped structure, and two sides of the stirring space 10 are respectively provided with a stirrer 2; the stirrer 2 is provided with a stirring shaft 21 having stirring blades 22 for pressing down the slurry while stirring the slurry so that the slurry rolls upward along the side wall of the stirring tank 1. The utility model discloses carry out the optimal design to the inner structure of agitator tank 1 to the single mode of current (mixing) shaft 21 horizontal mixing has been changed, make the ground paste can upwards roll along agitator tank 1's lateral wall in horizontal rotation, thereby realize three-dimensional stirring, effectively improved stirring efficiency, ensure that the ground paste stirring is even and intensive mixing, and then ensure that the ground paste proportion is even, avoid breaking or perforating of foaming in-process bubble, effectively improved the quality of foam concrete.

The structure and characteristics of the stirring tank 1 will be described in detail below:

referring to fig. 1 to 3, the stirring tank 1 includes two tank bodies 11 which are symmetrically arranged and in an oblique column shape, and the bottoms of the two tank bodies 11 are communicated with each other, so as to form a stirring space 10 in a V-shaped structure; a stirrer 2 is arranged in each of the two tank bodies 11. During operation, the two stirring shafts 21 drive the stirring blades 22 to rotate in the same direction, so that slurry in the two tank bodies 11 flows circularly and rolls up and down, the stirring efficiency and the mixing effect are fully improved, and the yield of the stirring tank 1 is effectively improved. To improve structural strength and stability, a reinforcing plate 111 may be provided between the two cans 11.

Referring to fig. 1 to 3, the included angle α between the two cans 11 is 30 to 70 °, i.e., the inclination angle β of the side wall of the can 11 is 15 to 35 °. During the stirring, the ground paste of agitator tank 1 bottom is rolled upwards under the effect of agitator 2, and this action can be approximately equated to be parabolic motion, consequently the utility model discloses the inclination beta of the 11 lateral walls of jar body has strictly been designed for the ground paste just falls on the lateral wall of agitator tank 1 when moving to the parabola summit, thereby guarantees that the ground paste fully stirs evenly in the shortest time, has ensured the stirring effect from this promptly, has fully improved stirring efficiency again. It should be noted that, the value range of the middle inclination angle β of the present invention is an appropriate range obtained after multiple tests, and when actually designing production, those skilled in the art can refer to the above description and calculate the value by combining the specific specification of the stirring tank 1 and the stirring speed of the stirrer 2, so as to obtain an optimized value.
