2. The oil phase materials in the on-site mixing truck are usually composed of engine oil and diesel oil, which are non-renewable resources, and we discard a large amount of waste engine oil every day in production and life, such as waste engine oil produced by mechanical maintenance, automobile 4S The waste engine oil replaced by the shop, etc. Improper disposal of these waste engine oils will cause harm to the environment, and it is also a waste of resources

Abstract

The invention relates to a method for producing a site mixed and charged emulsion explosive by utilizing waste engine oil. The method comprises the steps: a, preparing an aqueous-phase solution from 15-20% of water, 65-75% of industrial ammonium nitrate and 3-7% of industrial sodium nitrate based on the total weight; b, preparing an oil-phase solution from 1.5-2.0% of an emulsifier and 3.5-5% of the waste engine oil based on the total weight; c, preparing 0.5%, based on the total weight, of a sodium nitrite aqueous solution with the concentration of 20-40% in a foaming agent tank; d, pumping the prepared aqueous-phase solution and the prepared oil-phase solution to a corresponding aqueous-phase tank and a corresponding oil-phase tank; and e, conveying the aqueous phase and the oil phase with the weight ratio of 93.5:6 to an emulsification device, emulsifying, forming a emulsion colloid, then continuously conveying the sodium nitrite aqueous solution accounting for 0.5% of the total weight to a mixer, and carrying out mixed sensitization to form the emulsion explosive. The method has the advantages of high efficiency, environmental protection, and good economic benefits.

Description

technical field [0001] The invention relates to the field of emulsion explosives, in particular to a method for producing on-site mixed emulsion explosives using waste engine oil. Background technique [0002] The traditional production of emulsion explosives is to prepare explosives into packaged products in a fixed production line, and then package, store, and transport them to the blasting site for blasting operations. This production method has potential safety hazards in both storage and transportation. The on-site mixed explosives vehicle is an equipment that integrates the transportation, mixing and charging of raw materials and semi-finished products. It has the following characteristics: 1. It is safe and reliable. The charge truck does not transport the finished explosives. The raw materials of the explosives are filled in the silo. These raw materials are mixed at the explosion site according to a certain ratio and loaded into the blast holes. After 5-10 minutes ...
