System for moulding sand quality on-line inspection and humidity automatic control

Abstract

The invention relates to the technical field of processing systems for foundry sand, in particular to a system for moulding sand quality on-line inspection and humidity automatic control. An on-line detection system is arranged on a sand mixer and comprises a controller, and the controller is connected with a humidity sensor, a temperature sensor, a compact rate pressure transmitter and a strength and pressure transmitter. A humidity automatic control system is arranged on a sand supplying belt conveyor in front of a moulding machine, and the humidity automatic control system comprises an automatic water adding device connected with the controller. The system for moulding sand quality on-line inspection and humidity automatic control has the advantages that the on-line detection system arranged on a sand mixer ensures the constant compact rate and wet strength by detecting temperature and humidity, and the humidity automatic detecting system on the sand supplying belt conveyor in front of the moulding machine ensures a constant humidity value by analyzing the humidity and temperature of moulding sand. Combined control of the on-line detection system and the humidity automatic control system ensures quality performance of the moulding sand.

Description

technical field [0001] The invention relates to the technical field of casting sand processing systems, in particular to an online molding sand quality detection and humidity automatic control system in the sand processing system. Background technique [0002] In the process of sand treatment in the foundry, stable molding sand quality is an important condition to avoid the formation of product quality. This must solve the temperature and humidity of the sand during sand treatment from the shakeout machine to the sand mixer. influences. [0003] The improvement of the quality and precision of the molding sand in the molding line can directly help to reduce waste, reduce the scrap rate and defective castings, which can realize the return on investment in a short period of time, and the compaction rate and wet compaction strength affect the performance of the molding sand and even the performance of the casting process The two most important parameters of the function, how to...
