WIPO Patent Application WO/2019/127688
Kind Code:
A1
Abstract:
Disclosed is a high-viscosity liquid supply and discharge device (10), comprising a nozzle (1), liquid supply pipes (21, 22) and a bubble discharge pipe (3), wherein the bottom of the nozzle (1) is provided with a liquid outlet end (11), the liquid supply pipes (21, 22) are respectively connected to opposite side walls of the nozzle (1) near the liquid outlet end (11), and each of the liquid supply pipes (21, 22) has one end thereof extending into a cavity of the nozzle (1); the liquid supply pipes (21, 22) are further provided with bubble sensors (23, 24); the bubble discharge pipe (3) is arranged at the top of the nozzle (1), and the bubble discharge pipe (3) is provided with bubble discharge valves (310, 320, 330); and the bubble discharge valves (310, 320, 330) are configured to be opened to discharge bubbles when the bubble sensors (23, 24) detect that bubbles exist in the liquid supply pipes (21, 22) and/or the nozzle (1). In the supply and discharge device (10), a high-viscosity liquid flows into the nozzle (1) from the liquid supply pipes (21, 22) at the two sides of the nozzle (1), and by means of the bubble sensors (23, 24) on the liquid supply pipes (21, 22) and the bubble discharge pipe (3) connected to the nozzle (1), the high-viscosity liquid without bubbles can be discharged via the liquid outlet end (11) at the bottom of the nozzle (1).
