A device for preparing air-bubble concrete blocks

Abstract

The invention discloses an air cell concrete block preparation device, which relates to the technical field of engineering machinery, and comprises a base, a placing platform, an upper cover plate, a rotating mechanism, a feeding mechanism and an air hole crushing mechanism, and a hydraulic cylinder is built in the base , the placing table is installed on the output end of the hydraulic cylinder, and a mold groove is placed on the upper surface of the placing table. In the present invention, by setting the rotating mechanism and the pore crushing mechanism, driven by the first drive motor and the second output end of the drive motor, the swivel will produce different rotational speeds on the rotating shaft, and driven by the inertia of the cement slurry, the air bubbles near the side end surface of the mold groove will also Can be dispersed, after the swivel is rotated out of the mounting seat, the crushing plate is reset again under the elastic force of the spring, and its reciprocating movement can disperse the large-volume air bubbles accumulated on the inner wall of the mold groove through the micropores; By setting the rotating mechanism and the feeding mechanism, the size of the pores inside the concrete block can be controlled and evenly distributed.

Description

Technical field [0001] The present invention relates to the field of mechanical engineering, particularly, to a bubble concrete block manufacturing apparatus. Background technique [0002] Concrete block bubble, the bubble machine system through the foam blowing agent is sufficiently mechanically foamed, and the foam block within the mold and slurry uniformly mixed, and then closed by containing a large amount of the formed nature conservation pores new lightweight thermal insulation material, because of its unique structure and properties, it has been widely used in defense and military infrastructure projects and other fields. [0003] Preparation of a conventional apparatus using bubble concrete block bottom-up approach, the foam slurry tank filled with water, in particular using the bottom surface of the cloth are taken over a plurality of water-slurry tank, and then stirred by a planetary mechanism constant stirring it complete mixing. But we found that long-term use of the ...

AI Technical Summary

Problems solved by technology

However, the following disadvantages have been found in the long-term use process: 1. Multiple connecting pipes fill the mold groove with foam. When the bubbles are rising, the bubbles near the side end of the mold groove cannot be stirred by the agitator, and a large part of the product Hanging on the inner wall of the mold groove, forming a hanging bubble phenomenon, there will be large volume of irregular pores on the surface of the air-filled concrete block prepared after natural curing, resulting in the possibility of formation between two adjacent concrete blocks during application. The risk of through-holes reduces the performance of sound insulation and heat preservation; 2. Cut the air-filled concrete block longitudinally, and you will find that the internal air pores gradually increase in volume from the inside to the outside. The reason is that the agitator is always in one direction and rotates at a uniform speed. , so that the filled air bubbles are diffused and thrown out around the direction perpendicular to the rotation axis, and finally the concrete block with dense inner and outer sparse is heavy in weight and needs to be improved in strength
