Description

Technical Field

[0001] The utility model belongs to the technical field of colloid transportation, in particular to a quick-connect water film lubrication device for an on-site explosive mixing vehicle. Background Art

[0002] At present, the on-site mixed emulsion explosive production system is widely used in blasting projects in mining, water conservancy and hydropower, railway transportation and other mining and infrastructure construction fields. After the on-site mixed emulsion explosive vehicle is loaded with explosive raw materials or semi-finished products and drives into the blasting site, it uses the on-board system to continuously prepare them into explosives and complete the blasthole filling, realizing mechanized and efficient blasting operations.

[0003] At present, truck-made emulsion explosives are all pumped by curved-bar pumps and transported to the bottom of the blasthole through a flexible hose. When the truck is operating on-site to mix explosives, the explosives are transported over a short distance and can only transport explosives with high viscosity and water content. Due to the high viscosity of the explosives, the resistance during transportation is also large, resulting in a high delivery pressure, which poses certain safety hazards and can easily lead to safety accidents.

[0007] Furthermore, the water inlet component is circumferentially welded with the threaded connection component and the quick connector connection component.

The quick connector connection component is directly connected to the medicine delivery hose, and the water film isolates the contact between the explosives and the tube wall, thereby reducing the delivery resistance and achieving the purpose of reducing the delivery pressure.
