Title:
DEVICE AND METHOD FOR TRANSFERRING INDUSTRIAL EMULSION EXPLOSIVE
Document Type and Number:
WIPO Patent Application WO/2017/097005
Kind Code:
A1
Abstract:
A device for transferring an industrial emulsion explosive comprises: two piston-type transfer pumps (1); and a material storage bin (2). Each piston-type transfer pump (1) comprises: a supply tank (111, 121); a supply piston (112, 122); a piston rod (113, 123); and a drive cylinder (114, 124). The supply tank has a feed inlet and a discharge outlet. The supply piston (112, 122) is provided with a pull plate (101) and a communicating hole (102) in communication with a rod cavity and a rodless cavity. The piston rod (113, 123) is driven by the drive cylinder (114, 124) extend or retract. The piston rod (113, 123) is connected to a sealing plate (103) and a discharge switch valve (3) configured to control opening and closing of the discharge outlet of a corresponding one of the two piston-type transfer pumps (1). The device has a simple and compact structure and high stability in transferring a material, can be manufactured easily at low manufacturing costs, and is very safe. Also provided is a method for transferring an industrial emulsion explosive. The method comprises: supplying, by two pressure oil sources (5, 6), oil to respectively drive the two piston-type transfer pumps (1) to suck, pre-compress and transfer a material; and upon performing a switch, supplying, by the same pressure oil source (5), oil to cause the two piston-type transfer pumps (1) to compress and transfer the material simultaneously, and then performing a switch between the discharge switch valves (3), thereby achieving a pulseless and stable switching, and increasing transfer stability.
