Protection device for water and material supply failures of emulsion explosive emulsifier and its control method

Abstract

The invention discloses a protection device for water and material supply failures of an emulsion explosive emulsifier and its control method. The device comprises: an emulsifier, a computer collection and analysis system, and an alarm device. The device also includes electronic flow data collectors that are respectively connected to a water phase, an oil phase and the emulsifier. The emulsifier is in connection with the computer analysis system connected to the alarm device. The electronic flow collectors are installed at the water inlet or outlet of the emulsifier, and on an oil phase pipeline as well as a water phase pipeline. According to the invention, the water and material supply failures and other problems of the emulsifier are monitored in real time through the electronic flow data collectors, so that the device of the invention realizes automation, enhances response accuracy, and improves the intrinsic safety of emulsion explosive production, and also makes the production process more efficient, more beneficial, stabler and smoother.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring of emulsifier water cut-off and flow cut-off protection during the production process of emulsion explosives, in particular to a water cut-off and flow cut-off protection device for an emulsified explosive emulsifier and a control method thereof. Background technique [0002] Compared with other explosives, the performance of emulsion explosive is relatively stable, but it is a kind of explosive mixture after all, and combustion and explosion accidents may occur under certain conditions during the production process. In recent years, news about major explosion accidents in emulsion explosive production lines has occurred from time to time, and among the major explosion accidents that have occurred, explosion accidents caused by equipment and their control methods account for the vast majority. [0003] At present, most domestic emulsifiers are closed-type high-speed, small-gap two-sta...

AI Technical Summary

Problems solved by technology

In the prior art, the water cut-off and flow cut-off protection of the emulsion explosive emulsifier adopts the original manual control method, and the operator observes whether there is water flowing out of the cooling water outlet of the emulsifier through on-site observation and the personnel in the control room through video monitoring. To judge whether the water is cut off, judge whether the material is cut off by observing the oil-water phase flowmeter, and then control it by the on-site operator or the personnel in the control room through the emergency stop button. This manual control method has large errors and insensitive response

[0005] The Chinese utility model patent with application number CN201020167612.7 (publication number CN201658953U, publication date is December 1, 2010) describes an emulsifier with a non-contact sealing structure. There is an oil seal seat on the flange surface, and an oil seal is installed inside the oil seal seat. There is a spiral groove on the shaft section where the shaft matches the inner wall of the flange hole. There is a gap between the part with the spiral groove on the shaft and the inner wall of the flange. , this kind of mechanical seal still has potential safety hazards in the whole production process
