Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive testing technology, specifically to an emulsion explosive stability testing device. Background Technology

[0002] The stability of emulsion explosives refers to their ability to maintain their physical state and explosive properties without change. It is an important indicator for predicting the quality of emulsion explosives. Currently, common methods for characterizing the stability of emulsion explosives include natural storage, high and low temperature cycling, conductivity method, and observational method. Among these, the conductivity method is widely used due to its convenience. In the conductivity method, the emulsion explosive is usually immersed in water at a certain temperature for a certain period of time, and then the conductivity of the immersion water is measured using a conductivity meter. Since there is a direct proportional relationship between the amount of free ammonium nitrate precipitated from the emulsion explosive matrix and the conductivity, the amount of free ammonium nitrate precipitated from the emulsion explosive matrix can be reflected by measuring the conductivity of the immersion water, thereby reflecting the demulsification and crystallization of the emulsion explosive, and thus predicting its stability.

[0003] However, the emulsion explosive matrix is ​​highly sensitive to the immersion temperature. The amount of free ammonium nitrate precipitated from the emulsion explosive matrix varies with the immersion temperature. Although the conductivity method can obtain results quickly, the conductivity results are greatly affected by temperature and it is difficult to accurately reflect the stability of the prepared emulsion explosive. To improve the accuracy of the conductivity results in reflecting the stability of the emulsion explosive, it is necessary to maintain a constant temperature in the immersion water of the emulsion explosive, which is very inconvenient for the test personnel to operate. Utility Model Content

[0004] This invention provides a device for testing the stability of emulsion explosives, aiming to solve the problems mentioned in the background art, such as the low accuracy of existing conductivity methods in reflecting the stability of emulsion explosives and the inconvenience of operation for test personnel.

[0005] To solve the above problems, this utility model is implemented as follows: an emulsion explosive stability testing device includes a workbench and a conductivity meter and a constant temperature heating device disposed on the workbench. The constant temperature heating device includes a connecting plate disposed on the workbench, a concave placement groove disposed on the connecting plate, and a constant temperature heating plate disposed on the inner wall of the placement groove. An electric push rod is fixedly installed on one side of the workbench, a support plate is fixedly installed on the output rod of the electric push rod, and a temperature sensor is fixedly installed on the support plate.

[0006] When using this utility model device, a transparent cup containing water and explosives needs to be placed in a placement tank. A constant temperature heating plate on the inner wall of the placement tank heats the water in the transparent cup at a constant temperature. A temperature sensor detects whether the water temperature in the transparent cup has reached the preset temperature, and a conductivity meter detects the conductivity of the water in the transparent cup after the explosives have been soaked.

[0007] Furthermore, the emulsion explosive stability testing device also includes a moving mechanism mounted on the workbench for moving the constant temperature heating device. The moving mechanism includes a strip hole opened on the workbench, a slider slidably mounted on the inner wall of the strip hole, a sliding rod fixedly mounted on the inner walls of both sides of the strip hole, and a motor fixedly mounted on the bottom of the workbench. A screw is fixedly mounted on the output shaft of the motor. The screw is threadedly connected to the slider. The sliding rod is slidably connected to the slider. The connecting plate is fixedly mounted on the top of the slider.

[0009] Preferably, a display is fixedly installed on the top of the support plate, and a controller is fixedly installed on the bottom of the workbench.

[0010] Preferably, a housing is fixedly installed at the bottom of the workbench, and an inspection port is provided on the housing, with an inspection door provided on the inspection port.

[0014] Preferably, a weighing sensor is fixedly installed on the top of the connecting plate, and the placement slot is fixedly installed on the weighing sensor.

[0015] Compared with related technologies, the emulsion explosive stability testing device provided by this utility model has the following beneficial effects:

[0016] Compared with existing technologies, the emulsion explosive stability testing device provided by this utility model, through the use of a constant-temperature heating device and a temperature sensor, allows the emulsion explosive to be continuously immersed in water at a suitable temperature. This ensures that the amount of free ammonium nitrate precipitated from the emulsion explosive matrix is ​​not affected by the immersion temperature, and also ensures that the emulsion explosive is immersed in the optimal water temperature, thus guaranteeing that the amount of ammonium nitrate precipitated is accurately measured for conductivity, thereby improving the accuracy of the conductivity method in reflecting the stability of emulsion explosives. The use of a weighing sensor allows for weighing the water placed in the transparent cup, facilitating the operator to add the appropriate amount of emulsion explosive. The combination of an electric push rod and a support plate allows for vertical lifting and lowering of the temperature sensor and electrodes, enabling separate temperature and conductivity measurements of the water in the transparent cup. The use of a moving mechanism allows the placement tank to be moved directly below the temperature sensor or the conductivity meter electrodes, facilitating operator use.

[0017] In summary, the device of this invention has a simple structure and is easy to operate. It can quickly and accurately characterize the stability of emulsion explosives. The data of the entire detection process are accurate and reliable. It solves the problems of low accuracy in reflecting the stability of emulsion explosives by the existing conductivity method and the inconvenience of operation for test personnel.

[0024] This utility model provides a device for detecting the stability of emulsion explosives, such as... Figure 1-3 As shown, its structure includes: a workbench 1 with a strip-shaped hole, an electric push rod 2 fixedly mounted on the top of the workbench 1, and a support plate 3 fixedly mounted on the output rod of the electric push rod 2; a conductivity meter 4 mounted on the workbench 1, an electrode 5 for detecting emulsion explosives fixedly connected to the support plate 3; a slider 6 slidably mounted on the inner wall of the strip-shaped hole, a connecting plate 7 fixedly mounted on the top of the slider 6, a weighing sensor 8 fixedly mounted on the top of the connecting plate 7, a concave placement groove 9 fixedly mounted on the weighing sensor 8, a constant temperature heating plate 10 fixedly mounted on the inner wall of the placement groove 9, and a transparent cup 11 for storing emulsion explosives and water can be placed in the placement groove 9; a temperature sensor 12 fixedly mounted on the support plate 3; and a moving mechanism mounted on the workbench 1 for moving the placement groove 9. The moving mechanism includes: a motor 13 fixedly installed at the bottom of the workbench 1; a screw 14 fixedly installed on the output shaft of the motor 13, the screw 14 being threadedly connected to the slider 6; and a slide rod 21 fixedly installed on the inner walls of both sides of the strip hole, the slide rod 21 being slidably connected to the slider 6.

[0025] In this embodiment, the moving mechanism is used to move the transparent cup 11. When in use, the motor 13 is started, and the motor 13 drives the screw 14 to rotate. The screw 14 drives the slider 6 to slide horizontally on the slide bar 21. The slider 6 drives the connecting plate 7 to move. The connecting plate 7 drives the weighing sensor 8 to move. The weighing sensor 8 drives the connecting plate 9 to move. In this way, the transparent cup 11 can be moved directly below the electrode 5. Conversely, it can also be easily moved below the temperature sensor 12. The movement is relatively convenient.

[0026] In a further preferred embodiment of this utility model, a limiting rod 15 is fixedly installed on the top of the workbench 1, and the limiting rod 15 is slidably connected to the support plate 3. In this embodiment, the use of the limiting rod 15 can improve the stability of the support plate 3 during vertical movement and effectively reduce the supporting force of the electric push rod 2 on the support plate 3.

[0027] In a further preferred embodiment of this utility model, a display 16 is fixedly installed on the top of the support plate 3, and a controller is fixedly installed on the bottom of the workbench 1. In this embodiment, the display 16 can display the weight and temperature data of the detected emulsion explosive for the operator to observe, and the controller can facilitate the operator to control the device.

[0028] In a further preferred embodiment of this utility model, a housing 17 is fixedly installed at the bottom of the workbench 1. An inspection port is provided on the housing 17, and an inspection door 19 is provided on the inspection port. In this embodiment, the housing 17 serves to shield the moving mechanism, and the combined use of the inspection port and the inspection door 19 facilitates the operator's maintenance of the moving mechanism inside the housing 17.

[0029] In a further preferred embodiment of this invention, a plurality of anti-slip pads 18 are fixedly installed on the bottom of the housing 17, and the plurality of anti-slip pads 18 are all made of rubber. In this embodiment, the multiple rubber anti-slip pads 18 can increase the friction between the device and the tabletop, thereby improving the stability of the device on the tabletop and making it less prone to slipping.

[0030] In a further preferred embodiment of this utility model, a support block 20 is fixedly installed at the bottom of the workbench 1, and the support block 20 is rotatably connected to the screw 14. In this embodiment, the use of the support block 20 can provide better support for the screw 14, which can not only improve the stability of the screw 14 during operation, but also reduce the supporting force of the motor 13 on the screw 14.

[0031] When using the detection device of this invention to test the stability of emulsion explosives, firstly, a transparent cup 11 is placed in the placement slot 9, and water is added to the transparent cup 11. The weighing sensor 8 detects the weight of the water added to the transparent cup and displays the detected weight on the display 16. When the water in the transparent cup reaches the appropriate weight, a certain mass of emulsion explosive strip is cut and placed into the transparent cup 11. It can be assumed that the weighing sensor 8 is not necessary; if the transparent cup 11 has graduations, the volume of water added can also be measured. Next, the electric push rod 2 is activated, which drives the support plate 3 to descend vertically, allowing the probe of the temperature sensor 12 to extend into the transparent cup 11 to detect the temperature of the water in the transparent cup 11 in real time. The detected temperature is also displayed on the display 16. At the same time, a constant temperature heating... The hot plate 10 is activated to heat the transparent cup 11. When the water temperature rises to the optimal temperature, the constant temperature heating plate 10 keeps the water temperature at that temperature. After the emulsion explosive has been soaked in the water at that temperature for a preset time, the electric push rod 2 is activated again, which drives the support plate 3 to rise, so that the probe of the temperature sensor 12 leaves the transparent cup 11. Then, the moving mechanism is activated, which drives the slider 6 to slide smoothly on the strip hole. The movement of the slider 6 will further drive the connecting plate 7, the weighing sensor 8 and the placement groove 9 to move together until the transparent cup 11 is precisely moved directly below the electrode 5. Finally, the electric push rod 2 is activated again, which drives the support plate 3 to descend vertically, so that the electrode 5 can be inserted into the transparent cup 11. At this time, the electrode 5 is in contact with the water in the transparent cup 11, and the conductivity meter 4 begins to detect the conductivity of the water after soaking the emulsion explosive.

[0032] In summary, the emulsion explosive stability testing device provided by this utility model, through the use of a constant-temperature heating plate 10 and a temperature sensor 12, allows the emulsion explosive to be continuously immersed in constant-temperature water at a suitable temperature. This ensures that the amount of free ammonium nitrate precipitated from the emulsion explosive matrix is ​​not affected by the immersion temperature, and also ensures that the emulsion explosive is immersed in the optimal water temperature, thus guaranteeing that the amount of ammonium nitrate precipitated can be accurately measured for conductivity, thereby improving the accuracy of the conductivity method in reflecting the stability of emulsion explosives. This utility model, through the use of a weighing sensor 8, can weigh the water placed in the transparent cup 11, facilitating the operator to add the appropriate amount of emulsion explosive. The electric push rod 2, in conjunction with the support plate 3, can drive the temperature sensor 12 and electrode 5 to achieve vertical lifting and lowering, thereby enabling temperature and conductivity detection of the emulsion explosive in the transparent cup 11 respectively. The use of a moving mechanism allows the placement tank to be moved directly below the temperature sensor or the conductivity meter electrode, facilitating operator use.

[0033] In summary, the device of this invention has a simple structure and is easy to operate. It can quickly and accurately characterize the stability of emulsion explosives. The data of the entire detection process are accurate and reliable. It solves the problems of low accuracy in reflecting the stability of emulsion explosives by the existing conductivity method and the inconvenience of operation for test personnel.
