Abstract

In the production of ceramic green sheet, by means of the continuous caster, it is necessary to maintain a supply of liquid ceramic in the continuous caster doctor-blade slip hopper to a pre-established level. This is the primary function of the mobile system 10 and is accomplished by means of a pump 12 which transfers liquid ceramic to the doctor-blade slip hopper, upon demand signals from the liquid level sensor and control system 28.

Mobile System for Transfer of Ceramic Slurry

In the production of ceramic green sheet, by means of the continuous caster, it is necessary to maintain a supply of liquid ceramic in the continuous caster doctor-blade slip hopper to a pre-established level. This is the primary function of the mobile system 10 and is accomplished by means of a pump 12 which transfers liquid ceramic to the doctor-blade slip hopper, upon demand signals from the liquid level sensor and control system 28.

Upon initial start-up of pump 12 operation by the control panel pump pneumatic supply valve and regulator 34, liquid ceramic is pumped from the slip container 16 to the 3-way electro/ pneumatic diverter valve 20, thru the cast line 24 and on to the continuous caster doctor-blade slip hopper 25. Upon reaching the proper level in the slip hopper, a liquid level sensor 28 signal de-energizes solenoid valve 30, which, in turn, pneumatically actuates the diverter valve 20, which diverts the flow of liquid ceramic from the cast line 24, supplying the slip hopper, to the recirculating line 22, and back into the slip container 16. This system action of recirculation (when not replenishing the slip hopper) serves to prevent pump "dead-heading" and minimize the tendency of liquid ceramic stratification and settling.

As the liquid ceramic level in the slip hopper, diminishes to a pre-established low level (as liquid ceramic is fed to the continuously moving MYLAR* belt), a loss of the liquid level sensor 28 signal energi...
