Title:
DEVICE FOR INDUSTRIAL FURNACE CERAMIC SURFACING
Document Type and Number:
WIPO Patent Application WO/2005/071338
Kind Code:
A1
Abstract:
The invention relates to the pneumatic circuit of a device for ceramic surfacing a damaged refractory masonry (lining) of furnaces without cooling said furnaces. A chamber pump (1) is connected by means of a switch (20) to a compressed air source and uniformly and controllably supplies a powdery castable refractory mixture contained therein to a refractory tuyere (2) input in order to mix said mixture with oxygen at a specified ration and to supply it to a local repairable area. Said invention makes it possible to ensure the reliable and stable long-term operation of the device under conditions of repetitive on/off switchings of the compressed air supply for transporting the powdery castable refractory mixture. For this purpose, the switch (20) is associated with a pressure relieve filter (18) from the chamber pump cavity and is embodied in the form of a four-port on/off pneumatic distribution valve. The selected number of inputs and outputs of the pneumatic distribution valve automatically ensures a pressure pre-relief from the chamber pump into atmosphere during the switchings, thereby preventing the clogging of the holes by the refractory mixture transported from the chamber pump (1) through an aerator (5) and an aerating air pressure stabiliser (6).
