Stirring device and heat preservation and sound insulation board pouring system

Abstract

The invention belongs to the technical field of heat preservation and sound insulation board production and processing, and particularly relates to a stirring device and a heat preservation and sound insulation board pouring system. The stirring device comprises a stirring barrel, stirring blades and a valve, and a feeding port and a nozzle are formed in the barrel wall; and the feeding port and the nozzle are arranged at the upper half part of the barrel wall. The bottom of the stirring barrel is not provided with a closed-up material collecting structure, and the stirring barrel is of a straight-through structure in the whole vertical direction so that the wall hanging phenomenon of materials can be effectively reduced; the materials are directly released into a mold after being mixed into slurry and do not pass through a redundant conveying device any more, and the phenomenon of inaccurate feeding caused by material solidification is reduced to the maximum extent; and the stirring barrel has a self-cleaning function, turbid liquid generated by cleaning does not need to be discharged and is directly used as a solvent for next stirring, high-frequency cleaning of equipment is realized in the whole processing process, waste liquid is not generated, and the production process is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of production and processing of thermal insulation and sound insulation boards, and in particular relates to a stirring device and a pouring system for thermal insulation and sound insulation boards. Background technique [0002] As a kind of composite building material, thermal insulation and sound insulation board has good thermal insulation and sound insulation effects. It is mainly composed of cement-based pouring layer and prefabricated core layer. The prefabricated core layer is generally foam plastic or other polymer materials. The processing process is as follows: first inject cement slurry into the mold, cover the prefabricated core layer on the cement slurry before the slurry solidifies and keep the pressure for a period of time, after the slurry solidifies, it is combined with the core layer to form the thermal insulation and sound insulation board. In the prior art, during the pouring process, a ...

AI Technical Summary

Problems solved by technology

In the prior art, during the pouring process, a large amount of cement slurry is prepared first, and then the cement slurry is quantitatively injected into the mold in batches. The defect of this pouring method is that the prepared cement slurry needs to be continuously stirred during storage. In order to prevent its solidification, and the cement slurry will inevitably adhere to the inner wall of the equipment during the transportation process, which will cause blockage in the long run. In addition, the deposition of the slurry in the quantitative distribution device will lead to deviations in the final output slurry components, and this deviation will With the continuous increase of equipment service time, the pouring volume cannot meet the design requirements, and this problem needs to be solved urgently
