Safety interlock protection system and method for automatic explosive production line

Abstract

The invention discloses a safety interlocking protection system and method for an automatic explosive production line. The system comprises a main control unit, an emulsion preparation unit, a sensitization charging unit, and a packaging unit, wherein the emulsion preparation unit comprises an emulsion preparation control module, an emulsion preparation data storage module, an emulsion preparation drive adjustment module, and an emulsion preparation data collection module; the emulsion preparation control module is used for closed-loop control of emulsion matrix preparation of the emulsion unit; the emulsion preparation data storage module is used for storing required supply values and proportion curves of all raw materials of an emulsion matrix; the emulsion preparation driving adjustment module is used for adjusting the supply states of all the raw materials of the emulsion matrix; and the emulsion preparation data acquisition module is used for acquiring real-time data of each raw material of the emulsion matrix. According to the invention, the automation informatization degree of the production line is high; the flow, the temperature, the liquid level, the pressure and the equipment state in the whole production process can be monitored, the overall stability of a production system is guaranteed, and meanwhile, monitoring of the equipment state of the production line is facilitated.

Description

technical field [0001] The invention relates to the field of automatic production of explosives, in particular to a safety interlock protection system and method for an automatic production line of explosives. Background technique [0002] The main process of the production process of emulsion explosives includes raw material preparation, water-oil phase preparation, oil-water phase transportation, emulsification, charge sensitization, drug coil cooling, packaging and other processes. Each process has a corresponding production line, specifically the water-oil phase preparation System, emulsion pharmaceutical system, sensitized charge system, cooling delivery system, automatic packaging system and other complete sets of production equipment and instruments, each production system line is connected in sequence to form the entire emulsion explosive production line, such as the Chinese invention patent with application number 201310557097.1, A packaging line for columnar explos...

Problems solved by technology

[0003] However, the existing production line safety interlock protection system is not perfect. For example, the Chinese utility model patent with application number 201620078001.2 discloses an explosive linkage production system, which cannot make timely and accurate intelligent judgments based on actual production conditions.

That is, milk making and powder charging, powder charging and packaging cannot realize follow-up intelligent matching, resulting in low production capacity of the whole line; only simple safety interlock shutdown of front and rear processes can be realized, and intelligent matching system of production capacity cannot be realized, and there is no self-diagnosis function, and the equipment runs Insufficient stability; after entering the interlock protection, it is easy to cause unstable production quality
