Weighing mixing control system in aerated concrete production line

Abstract

The invention discloses a weighing mixing control system in an aerated concrete production line. The system comprises a feeding module, a water supply module, a heat supply module, a weighing metering module, a temperature control module, an alarm, a remote fault diagnosis module and an information management module. Adopting the system provided by the invention, technical workers on-site can achieve real-time monitoring management through an industrial personal computer, and the superior can also master the state of production and production in office. In addition, the functions of remote access programming and diagnosis provided by the system enable manufacturers thousands of miles away to access to equipment and diagnose fault without going out.

Description

technical field [0001] The invention belongs to the technical field of mixer automation control, in particular to a control device and system for an aerated concrete mixing station. Background technique [0002] Air-entrained concrete is a new type of wall building material. It is unique in that it is a very lightweight new type of building wall material for thermal insulation. The biggest advantage of aerated concrete is to save land resources without wasting a lot of arable land, and its raw material sources are very extensive. Ash sand, slag, fly ash and coal gangue are all raw materials for aerated concrete, and aerated concrete The performance characteristics of concrete are very superior, with very good machinability and heat insulation ability, and very strong plasticity, can be planed and sawed, and has very good processing characteristics. Air-entrained concrete is a multifunctional material that integrates load-bearing and thermal insulation. According to the curr...

AI Technical Summary

Problems solved by technology

The weighing and mixing system of the foreign aerated concrete production line is relatively intelligent and precise, but the structure is very complicated, it is difficult for ordinary production workers to operate, and there are high requirements for the skills of the workers

and very expensive

Although the price of the domestic aerated concrete production line batching and mixing system is cheaper than that of foreign countries, but the intelligence and precision are not high, it is difficult to meet the production requirements. Its problems mainly include the following aspects: (1) Hopper door or screw feeder The action lag time and the random change of the remaining material (impulse) in the air lead to excessive batching errors; (2) The principle of the weighing part of the weighing and mixing control system of the existing aerated concrete production line is the representative weight generated by the sensor and the frequency converter. The electric signal is collected by the single-chip microcomputer after the signal amplification module. This control method has a large signal interference and a high failure rate; (3) The database of the weighing and mixing control system of the existing aerated concrete production line is not perfect, and the aerated concrete formula database and production The function of the process database is not perfect, and the ratio of raw materials cannot be edited; (4) The weighing and mixing control system of the existing aerated concrete production line does not have a production management sub-module, and the system cannot be managed in real time; (5) The existing aerated concrete production line The water supply system of the weighing and stirring control system of the production line uses a water pump to directly supply water, which has a low degree of automation and relatively large errors; (6) The heating system of the weighing and stirring control system of the existing aerated concrete production line uses a hot water supply method, which wastes resources; (7) The weighing and mixing system of the existing aerated concrete production line cannot perform remote access programming and fault diagnosis
