Spraying system for casting workshop

Abstract

The invention discloses a spraying system for a casting workshop, and belongs to the technical field of casting. The system comprises a medicine liquid storage device, a spraying device and a controldevice; an outlet of the medicine liquid storage device is connected with an inlet of the spraying device; the spraying device is mounted at the middle upper part of the casting workshop for sprayingthe whole casting workshop; the control device comprises an electric control cabinet, a PLC arranged in the electric control cabinet, and a clock unit and a gear control device arranged in the PLC; acontrol end of the PLC is connected with the spraying device; and after the gear control device is communicated, the PLC controls the spraying device to repeat actions according to present time of theclock unit and according to a mode of intermitting by a certain of time length after spraying by a certain of time length. The system can reduce the temperature and remove the dust and harmful gas atthe same time, can accurately control the spraying quantity, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a spray system for a foundry workshop. Background technique [0002] The foundry industry is a key industry of my country's national economy. The dust and harmful gases generated during the casting production process not only cause harm to the health of workshop workers, but also cause great pollution to the external environment. Moreover, the hot and stuffy environment in the foundry also brings discomfort to the workers, which can easily cause nausea, dizziness, heatstroke and other serious consequences. Therefore, research on the treatment of dust and harmful gases in the foundry and improving the working environment in the foundry are issues that cannot be ignored in the foundry industry. [0003] For the high temperature and dust problems in the foundry, some existing technologies use a high-pressure spray system to cool, humidify and remove dust in the foundry. The worki...

Problems solved by technology

[0004] The inventor found in the research process that the problem with this solution is that it is difficult to accurately control the spray volume of the spray system. When too much water mist sprayed from the atomizing nozzle causes the air humidity to reach saturation, the water mist will Water droplets are formed, and the water droplets react with harmful gases to form acid rain and fall on the casting equipment, thereby causing corrosion to the equipment; when the water mist sprayed from the atomizing nozzle is too little, the effect of cooling, humidifying and dust removal will be unsatisfactory

However, this method of spraying by adding agents is mostly aimed at local areas in the foundry. When used in the entire foundry, there is still the problem that the spray volume of the above-mentioned spray system is difficult to accurately control.
