Problems solved by technology

Its disadvantage is that it does not solve the functions of automatic sampling, real-time detection, closed-loop control, etc., especially does not consider the error caused by the surface tension of the measuring liquid to the measurement result.
Therefore, the existing rapid density detectors for emulsion explosives cannot realize automatic sampling, analysis and comparison of density detection results, no alarm function, and cannot realize automatic adjustment of density, which has hysteresis for production guidance

Embodiment 1

[0027] First, the control center 41 controls the solenoid valve unit 11 to open, and the sample outlet unit 12 takes out the sample, and enters the container filled with the solution on the first weighing device 21 through the sample delivery tube unit 13, and discharges the corresponding volume of the solution. into the empty container on the second weighing device 22 to measure the quality and volume of the sample; the weighing sensor is connected with the transmitter to convert the physical quantity into an analog signal, and the analog signal is converted into an available signal using the weighing signal conversion unit 31 Based on the digital signal of the density calculation unit 33, then execute the sample size judging unit 32, when the sample mass is greater than or equal to 86g, only execute the density calculation unit 33 to obtain the density detection value; the density calculation unit 33 utilizes the density calculation formula ρ=(W 3 +W 4 -W 1 -W 2 ) / (W 4 -W...

Embodiment 2

[0033] The invention is used to detect the density of steel with any shape to verify the universality of the density detection of the invention. First, directly put a certain amount of sample into the container full of solution on the first weighing device 21, and discharge the corresponding volume of solution into the empty container on the second weighing device 22 to measure the quality of the sample and volume; the weighing sensor is connected with the transmitter, and the physical quantity is converted into an analog signal, and the analog signal is converted into a digital signal that can be used for the density calculation unit 33 by using the weighing signal conversion unit 31, and then executes the sample size judging unit 32, when the sample When the quality is greater than or equal to 86g, only the density calculation unit 33 is executed to obtain the density detection value; the density calculation unit 33 utilizes the density calculation formula ρ=(W 3 +W 4 -W 1...

Abstract

The invention relates to an on-line rapid detection system for density of an emulsion explosive semi-finished product, which comprises an automatic sampling module, a serial sensor module, a data processing and calculating module, a center control module and a display control module. The system is characterized in that a feeding solenoid valve in the automatic sampling module is switched on, the automatic on-line sampling is realized through a sample outlet and a sample transmission pipe; the sample enters into the serial sensor module through the sample transmission pipe, the sample quality and volume signals can be obtained by two weighing machines and transmitters, and are transmited to the data processing and calculating module; the density detection value is obtained by a weighing signal transition unit, a sample amount determine unit, a density calculating unit and a density correction unit, when the density detection value is provided in the preset value scope, the system enables normal operation; when the density value is greater than the preset value scope, the alarm is carried out, and the feeding speed of a density conditioning agent is changed, the density of the emulsion explosive semi-finished product is adjusted; when the density value is less than the preset value scope, the alarm is carried out and the system is stopped, then the operation is continued after the technological parameter is changed. The on-line rapid detection system can realize the integrated function of automatic sampling, rapid detection and machine stopping by alarming.

Description

technical field [0001] The invention is an on-line rapid detection, alarm shutdown and density adjustment system for the density of emulsion explosive semi-finished products, in particular an on-line rapid detection system for the density of emulsion explosive semi-finished products. Background technique [0002] Emulsion explosives are the leading products of industrial explosives in my country. With the wide application of emulsion explosives, their quality has attracted more and more attention. Density is an important performance parameter of emulsion explosives, which affects the detonation sensitivity, detonation velocity and performance of emulsion explosives, and even affects the quality of its products. Although the production process of emulsion explosives has undergone three stages of development from discontinuous, semi-continuous to continuous, the density detection of semi-finished emulsion explosives is still carried out by offline and manual methods.
