The utility model provides an automated defoamer feeding device, including a defoamer storage tank, a defoamer delivery pump, a pipeline filter, a defoamer intermediate tank, an automatic regulating valve, a flowmeter, and a pressure transmitter. This automated defoamer feeding device solves the current problems in the kiln industry where defoamer feeding operations are prone to unstable flow, poor process stability, and low defoaming efficiency due to manual adjustment. It also solves the current traditional feeding system, which results in complex system piping design and equipment control due to the use of rotor flowmeters. The automated defoamer feeding device greatly reduces the operational differences caused by human instability. The automated defoamer feeding system can automatically control feeding, reduce manual operation, and facilitate production. It can accurately measure and facilitate production quality control. The pipeline is simple to set up, reducing the number of redundant pipelines and valves, and reducing the number of nodes that may cause problems. It can stably and effectively provide defoaming agent for glass kilns, reduce the thickness of the foam layer in the kiln, improve the defoaming efficiency of the glass melting process, improve the quality of back-end products, reduce the erosion of the kiln crown, and extend the service life of the kiln. Utility Model Content

[0003] To address the problems of the prior art, the present invention provides an automatically controlled defoamer feeding device, primarily comprising a defoamer intermediate tank volume control system and a spray gun flow control system. The defoamer intermediate tank uses a remote level gauge (e.g., a magnetic flap, magnetostrictive, remote float, radar, ultrasonic, differential pressure, or other remote level gauges) to display and control the liquid level (or alternatively, a weighing module to display the weight).

Through the remote transmission of pneumatic control valves, electronic flow meters and pressure transmitters, real-time monitoring of the defoaming agent spray gun feeding data is achieved, which can automatically control the feeding, reduce manual operations, facilitate accurate measurement of production, and be more conducive to production quality control. It reduces the number of redundant pipes and valves, reduces the number of problem nodes, and can stably and effectively provide defoaming agents to glass kilns, reduce the thickness of the foam layer in the kiln, improve the defoaming efficiency of the glass melting process, improve the quality of back-end products, reduce the erosion of the kiln crown, and extend the service life of the kiln.
