Title:
SYSTEM AND METHOD FOR REALIZING CONTINUOUS ADDITION OF SAND INTO PRE-MIXED ABRASIVE WATER JET BY HIGH-PRESSURE MORTAR PUMP
Document Type and Number:
WIPO Patent Application WO/2020/244106
Kind Code:
A1
Abstract:
Disclosed in the present invention is a system for realizing continuous addition of sand into a pre-mixed abrasive water jet by a high-pressure mortar pump, the system comprising a clear water barrel, a mortar stirring barrel, a high-pressure clear water pipeline, a high-pressure mortar pipeline, a high-pressure jet pipeline, and a tee pipe. The high-pressure clear water pipeline is provided with a high-pressure clear water pump and a first pressure gauge sequentially in a water flow direction; the high-pressure mortar pipeline is provided with a high-pressure mortar pump, a second pressure gauge and an adjusting ball valve sequentially in a mortar flow direction; and an outlet of the high-pressure jet pipeline is connected to a high-pressure spray nozzle. Further disclosed in the present invention is a method for realizing continuous addition of sand into a pre-mixed abrasive water jet by the high-pressure mortar pump. According to the present invention, the characteristic of the high-pressure mortar pump being able to carry small particles of abrasive sand is ingeniously utilized, an existing way of mixing water and sand in a high-pressure state is changed into a way of mixing the water and the sand into high-concentration mortar in a normal-pressure state, and then mixing the high-concentration mortar with high-pressure clear water to form the high-pressure abrasive water jet with an appropriate concentration, which has the advantages of convenience, continuous sand addition, and convenience in operation.
