Description

Technical Field

[0001] The utility model belongs to the field of emulsion explosive raw material detection, in particular to a mobile ammonium nitrate crystallization point detection device. Background Art

[0002] Emulsion explosives are commonly used industrial explosives in mining. Their main components are inorganic salt oxidants based on ammonium nitrate as water phase, and form a W / O type emulsion matrix with the oil phase. The temperature at which ammonium nitrate precipitates from the aqueous solution is called the crystallization point. Once the components and ratios of the aqueous solution are determined, its crystallization point is a fixed value. Therefore, accurately measuring the crystallization point of the ammonium nitrate solution is a very important link in controlling product quality during the production of emulsion explosives. At present, emulsion explosive manufacturers mainly set up detection devices in the production workshop. The detection device includes a configuration tank, a controller, a temperature sensor, a sampler, a feed valve, a discharge valve and a sampling pump. There is a first pipeline between the top of the sampler and the configuration tank; there is a second pipeline between the bottom of the sampler and the configuration tank, and the feed valve and the sampling pump are arranged on the second pipeline; the discharge valve is arranged on the first pipeline, and the sampling pump pumps the aqueous solution in the configuration tank into the sampler for detection.

[0003] The existing detection device is connected to the ammonium nitrate solution preparation tank as a whole. The structure of this device is complex and the cost is high. When there are multiple production lines in a production workshop, different production lines need to be equipped with multiple detection devices, which increases the investment cost of the enterprise. In addition, the existing detection device is not convenient for testing the ammonium nitrate solution when it enters the factory, which makes it inconvenient to control the quality of the produced emulsion explosives. Utility Model Content

[0004] The utility model aims to provide a mobile ammonium nitrate crystallization point detection device, which has a simple structure and is easy to move, thereby reducing enterprise costs and improving the quality of emulsion explosives.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a mobile ammonium nitrate crystallization point detection device, including a detection cup, a controller and a temperature sensor electrically connected to the controller, a display screen, a start button, an indicator light and a magnetic stirrer, the detection cup adopts a hollow double-layer structure, the cup mouth of the detection cup is an eight-shaped structure, the bottom lower end surface of the detection cup is provided with an electrical installation part, the controller, the start button, the indicator light, the display screen and the motor of the magnetic stirrer are arranged in the electrical installation part, the stirring rod of the magnetic stirrer is arranged in the detection cup, and the temperature sensor is arranged on the side wall of the detection cup.

[0006] Furthermore, the detection cup is a transparent double-layer cup, and the outer surface of the detection cup is provided with a measurement scale.

[0007] Furthermore, it also includes a liquid level sensor, which is inserted into the detection cup and is electrically connected to the controller.

[0008] Furthermore, the voice prompt device includes a speaker and a voice chip, and the voice chip is electrically connected to the speaker and the controller respectively.

[0009] Furthermore, temperature sensors are provided at the upper, middle and lower parts of the detection cup, and each of the temperature sensors is electrically connected to the controller respectively.

[0010] Furthermore, a handle is provided on the outer side wall of the detection cup.

[0011] Compared with the prior art, the ammonium nitrate crystallization point detection device provided by the utility model has the following beneficial effects:

[0012] The ammonium nitrate crystallization point detection device provided by the utility model has a simple structure, and the detection liquid is directly collected through the detection cup. The detection cup adopts a double-layer structure to ensure the safety of personnel. The controller, temperature sensor, display screen, indicator light and magnetic agitator at the lower end of the detection cup are used for automatic detection. The whole device is easy to carry and move. The magnetic agitator is used to achieve uniform cooling of the sampled solution, and the accuracy of crystallization point measurement is improved. The detection device can be applied to multiple production line detection, reducing the production cost of the enterprise. At the same time, the mobile ammonium nitrate crystallization point detection device can not only realize the automatic detection function, but also can perform detection when the ammonium nitrate solution enters the factory, thereby improving the quality control of emulsion explosives.

[0013] The crystallization point temperature detected by the detection device is automatically read through the voice prompt device, which is more intelligent and convenient without the need for manual reading, and also avoids errors in manual reading.

[0014] Temperature sensors are arranged at the upper, middle and lower parts of the detection cup, thereby improving the accuracy of measuring the crystallization point of the ammonium nitrate solution. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiment 1:

[0020] See also Figure 1 As shown, a mobile ammonium nitrate crystallization point detection device includes a detection cup 1, a controller and a temperature sensor 7 electrically connected to the controller, a display screen 3, a start button 5, an indicator light 6 and a magnetic stirrer 4. The controller is an STM32 series single-chip microcomputer. The magnetic stirrer includes a motor, a magnet and a stirrer. The motor is a servo motor. The mouth of the detection cup 1 is in an eight-shaped structure. The eight-shaped structure facilitates the detection cup to directly receive materials through the mouth of the cup. The outer wall of the detection cup 1 is provided with a handle 1-1, which facilitates holding the detection cup. The detection cup 1 adopts a hollow double-layer structure to avoid being scalded by the detection liquid in the detection cup. The detection cup 1 adopts a transparent double-layer cup made of glass, and the outer surface of the detection cup 1 is provided with a measuring scale to facilitate quantitative detection. Or a double-layer cup with a glass liner is used.

The upper, middle and lower parts of the detection cup 1 are all provided with temperature sensors, and each of the temperature sensors 7 is electrically connected to the controller respectively. By setting the upper, middle and lower three temperature sensors, the temperature changes of the three points of the detection cup are set respectively, and the average temperature of the three temperature measurement points is used as the crystallization point temperature of the ammonium nitrate solution, so that the measurement data is more accurate.

[0022] In summary, the ammonium nitrate crystallization point detection device provided by the utility model, by pressing the start button 5, the indicator light 6 lights up after starting, the temperature sensor 7 obtains the temperature of the aqueous solution in the detection cup in real time, and uses physical properties. When the temperature of the aqueous solution decreases and crystals precipitate, an exothermic phenomenon occurs, and the temperature of the ammonium nitrate solution will rise. At the same time, the temperature sensor captures the temperature at the moment of temperature recovery, and the temperature at the moment of recovery is the crystallization point of the ammonium nitrate solution. The temperature change point detected by the temperature sensor is transmitted to the display screen through the controller. After the detection, the indicator light of the controller goes out, indicating that the test experiment is over. Compared with being fixed in the production workshop, the ammonium nitrate crystallization point detection device of this structure is easy to move and carry, and is more convenient to use.
