Explosion venting device of powder emulsion explosive matrix pump

Abstract

The invention discloses an explosion venting device of a powder emulsion explosive matrix pump. The explosion venting device of the powder emulsion explosive matrix pump comprises a pressure release component installed on the powder emulsion explosive matrix pump and a matrix collection component installed below the pressure release component, wherein the pressure release component comprises an explosion venting slice in a right arch shape, and an upper clamp holder and a lower clamp holder which are used to install the explosion venting slice in the right arch shape, the upper clamp holder and the lower clamp holder are fixed through an upper flange and a lower flange, the matrix collection component is composed of an outer cylinder, an inner cylinder with the upper end and the lower end open, a flange and a hopper, the upper end of the outer cylinder and the upper end of the inner cylinder are connected in seal mode, and the hopper is installed at the lower end of the outer cylinder. By adopting the technical scheme, the explosion venting device of the powder emulsion explosive matrix pump is simple in structure, convenient to install and demount, easy to clean, and safe and reliable, and eliminates potential damage on operating personnel.

Description

technical field [0001] The invention relates to the field of emulsion explosives, in particular to an explosion venting device for a powdery emulsion explosive matrix pump. Background technique [0002] The pumping process is an indispensable and important part of the continuous emulsion explosive production process, and it is also a relatively accident-prone process in the production of emulsion explosives. The pumping process inevitably produces certain mechanical effects on the material medium. Studies have shown that bubbles generated by mechanical effects inevitably exist during the preparation of the emulsified matrix, and these are ideal explosion "hot spots". During the pumping process, when it encounters severe friction, high temperature, extrusion, collision and other mechanical effects, it may explode. In order to prohibit the overpressure operation of the powdery emulsion explosive matrix pump, a burst vent is installed in the outlet pipe of the equipment at the...

AI Technical Summary

Problems solved by technology

At present, the explosion venting devices of matrix pumps on the market lack the matrix collection container when the explosion vent ruptures. Due to the instantaneous rupture of the explosion vent, the temperature of the discharged matrix is ​​high, and it is difficult to predict when to remove it. When the matrix is ​​discharged to the ground, it will splash. , prone to safety accidents, causing injury to operators
