Abstract

The invention discloses a control system for automatically preparing an aqueous-phase solution of emulsified explosive. The control system comprises an ammonium nitrate water solution storage tank, a sodium nitrate water solution storage tank, a hot water storage tank, a first aqueous-phase tank and a second aqueous-phase tank (the first aqueous-phase tank is a tank A and the second aqueous-phase tank is a tank B), wherein the ammonium nitrate water solution storage tank, the sodium nitrate water solution storage tank and the hot water storage tank are all located above the first aqueous-phase tank and the second aqueous-phase tank; after being connected in parallel, the ammonium nitrate water solution storage tank, the sodium nitrate water solution storage tank and the hot water storage tank are communicated with the first aqueous-phase tank and the second aqueous-phase tank; the sodium nitrate water solution storage tank is internally provided with a steam coiled pipe, and an electronic scale is arranged at the bottom of the sodium nitrate water solution storage tank; a steam coiled pipe is arranged in the hot water storage tank. The control system disclosed by the invention has the beneficial effects that 1, a calculation process of preparing the aqueous-phase solution by an operator is simplified, and an automation level is improved; 2, the newly-arranged sodium nitrate water solution storage tank and hot water storage can be arranged at the periphery of a dangerous workshop, a phenomenon that the quantity of people in the dangerous workshop in a aqueous-phase solution preparation process is avoided, and the safety in a production process of the emulsified explosive is improved.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to a control system for automatically preparing an emulsion explosive aqueous phase solution. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In the production process of emulsion explosives in the prior art, it is necessary to prepare an aqueous phase solution for production use. The components of the aqueous phase solution are ammonium nitrate, sodium nitrate and water, and the density of the prepared aqueous phase solution is controlled at 1.415-1.425g / cm 3 between. [0004] There is one ammonium nitrate aqueous solution storage tank with a capacity of 120 tons, and two aqueous phase tanks with a capacity of 8.5 tons (used alternately during production to achieve continuous production). The current operation method for preparing the aqueous p...

Problems solved by technology

[0012] 1. The calculation ability of the batching operator is relatively high, and the calculation process is cumbersome;

[0013] 2. It is necessary to manually open and close each valve, and the automation level needs to be improved;

[0014] 3. It is necessary to manually detect the density of the water phase. Frequent detection increases the workload of the monitor, and the level of automation needs to be improved.
