Flow mixing apparatus of viscous ammonium nitrate fuel oil explosives

Abstract

The invention discloses a flow mixing apparatus of viscous ammonium nitrate fuel oil explosives. A mixing tube is of straight-through tube structure; the front of the mixing tube is provided with a reducing segment; the reducing segment is of front-rear symmetry; the diameter of the reducing segment decreases gradually from front to rear and then increases gradually; the top of the smallest part of the reducing segment is provided with a feed port; a glue storage container is arranged above the feed port; a discharge port at the bottom of the glue storage container is communicated with the feed port; the inner wall of the rear of the mixing tube is fitted with a guide plate that enables a viscous ammonium nitrate fuel oil explosive be backwardly conveyed in spiral form. The flow mixing apparatus of viscous ammonium nitrate fuel oil explosive has reasonable design and simple structure, is easy to implement and low in production cost, is applicable to the field real-time making of viscous ammonium nitrate fuel oil explosives before charging, ensures uniform mixing and high production efficiency, and allows only the materials of explosives to be directly mixed into viscous ammonium nitrate fuel oil explosives on site during the steps such as transport and storage such that the steps of transport and storage and the like are greatly less dangerous, and the advantages of viscous ammonium nitrate fuel oil explosives are ensured.

Description

technical field [0001] The invention relates to a device for airflow mixing viscous ammonium oil explosives. Background technique [0002] In China, the current viscous ammonium oil explosives used in underground mine mining occupies a large proportion. Compared with expanded ammonium nitrate explosives, ammonium oil explosives, heavy ammonium oil explosives, emulsion explosives, etc., they have good bonding with blastholes and high charge density. , less amount of returned medicine, no shaking hands during tube delivery operation, simple equipment and other advantages. [0003] Viscous ammonium oil explosives are made by mixing ammonium oil explosives with polyacrylamide glue. Due to the inherent viscous characteristics of polyacrylamide glue, ordinary paddle stirring and mixing will often destroy the structure of the glue and cause the explosive to lose its proper viscosity. Using the spiral mixing method, the polyacrylamide colloid is often wound on the spiral shaft, re...

AI Technical Summary

Problems solved by technology

Using the spiral mixing method, the polyacrylamide colloid is often wound on the spiral shaft, resulting in uneven mixing

Both of these results will seriously affect the quality of viscous ammonium fuel explosive products

[0004] Viscous ammonium oil explosives are classified as finished explosives in the civil explosive industry and are not allowed to be mixed in the ground station, and the general ground station does not have the license for this production capacity
