A special lightweight concrete production device and process

Abstract

The invention discloses a special lightweight concrete production device and process, including a mixing cylinder, a processing cylinder and a recovery box. Pressure sensors are installed on the four corners of the lower surface of the mixing cylinder, and a protective shell is arranged on the outside of the mixing cylinder. A stirring rod is installed inside the mixing cylinder, and a stirring motor is connected to the lower end of the stirring rod. The processing cylinder is arranged on the left side of the protective shell, and a crushing shaft is installed inside the processing cylinder, and a Crushing motor, and the right side of the crushing motor is provided with a liquid pump, the lower end of the liquid pump is installed with a connecting pipe, and the lower end of the connecting pipe is connected with a conduit, the recovery box is installed on the outer edge of the lower end of the turntable, and the lower end of the turntable The middle position is connected with a rotary motor. The present invention arranges the whole set of devices, which can timely inject the mixed concrete into molding process, and the whole operation process can be purely mechanical, which greatly saves the labor cost.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a special lightweight concrete production device and process. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Lightweight concrete (concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it is formed with a large number of small closed pores and has Concrete products of considerable strength. The production of lightweight concrete (foamed concrete) is usually prepared by mechanically preparing the foaming agent aqueous solution into a foam, and then adding the foam to the slurry composed of si...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special lightweight concrete production device and process, which solves the problem that foam and slurry are easily mixed unevenly during the production process of special lightweight concrete on the market, and it is difficult to inject concrete into the mold in time. In the process, the whole process requires a lot of manual operations, which is not only time-consuming and labor-intensive, but also has low production efficiency.
