Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive production equipment and control systems, and in particular to an ammonium nitrate density detection device. Background Technology

[0002] Emulsion explosives are commonly used industrial explosives in mining. Their main component is an aqueous phase composed primarily of ammonium nitrate as an inorganic salt oxidant, forming a W / O emulsion matrix with an oil phase. Once the composition and ratio of the aqueous solution are determined, its density is constant. Therefore, accurately measuring the density of the ammonium nitrate solution is a crucial step in controlling product quality during the production of emulsion explosives. Currently, emulsion explosive manufacturers generally use conical flasks for sampling and manual measurement to determine the density of the ammonium nitrate solution. This method often results in inaccurate density measurements due to variations in personnel skills and operating procedures. Automated detection devices not only improve the accuracy of density measurements but also eliminate safety risks to personnel. Furthermore, the "14th Five-Year Plan for the Safety Development of the Civil Explosives Industry" emphasizes the development and application of online real-time detection, monitoring, and minimally invasive (unmanned) technology equipment to effectively reduce the number of personnel on the production line.

Therefore, the signal emitted by the density sensor 200 is converted into an electrical signal by the control circuit 106 and sent to the first control chip 105 and the second control chip 104 for signal transmission. At the same time, the crystal oscillator 103 can provide a stable pulse for the control circuit. Furthermore, the resistor array 102 ensures that the density signal emitted by the density sensor 200 can be displayed in the display unit 101.

[0042] Preferably, the control loop 106 further includes a sliding resistor, through which the density sensor 200 is electrically connected to the control circuit. Thus, the sliding resistor ensures a proper connection between the density sensor 200 and the control circuit.
