Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to a device for testing the reversion capability of emulsion explosives. Background Technology

[0002] When loading emulsion explosives into vertical or inclined blast holes with downward-facing openings, the emulsion explosives may flow out of the blast holes due to gravity. This is called emulsion explosive backflow. This situation increases the difficulty of loading emulsion explosives and extends the construction period. It is necessary to test the emulsion explosive backflow situation so that the construction method can be adjusted during actual loading. Therefore, an emulsion explosive backflow capability testing device was designed. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a device for testing the reversion ability of emulsion explosives, which can detect the reversion ability of emulsion explosives and allows for adjustable angle testing, enabling multi-angle testing and providing more reliable experimental data.

[0005] Preferably, the detection tube includes a storage tube and a transparent tube. A fitting ring that fits with the deflection cylinder is fixed at the connection between the storage tube and the transparent tube. An insertion port is opened on the surface of the storage tube, and an insertion plate is fitted inside the insertion port. A first ventilated end cap is fitted at the end of the storage tube away from the transparent tube, and a second ventilated end cap is fitted at the end of the transparent tube away from the storage tube.

[0006] Preferably, the insert plate includes two models, namely insert plate A and insert plate B.

[0007] Preferably, the angle measuring device includes a mounting plate fixed to the side wall of the fixed ring and a positioning ring fitted on the surface of the deflection cylinder.

[0009] Preferably, the surface of the deflection cylinder is fixed with a fixing plate for fixing to the first movable connecting seat, one end of the deflection cylinder is provided with a vent hole, and the other end of the deflection cylinder is fixed with a flange ring that docks with the detection tube.

[0010] The beneficial effects of this invention are as follows: by cooperating with the start-up drive motor and the telescopic cylinder to drive the deflection cylinder to deflect at a certain angle, and by using an angle measuring device to measure the deflection angle of the deflection cylinder, the emulsion explosive return capability test can be carried out at a fixed angle. Then, by injecting the emulsion explosive into the storage tube of the detection tube, during the test, the detection tube is inserted into the deflection cylinder at a determined angle. The emulsion explosive return capability test can be carried out by changing the insertion and removal. This device can adjust the angle for testing, and multi-angle testing is possible, making the experimental data more reliable. Attached Figure Description

Detailed Implementation

[0017] Reference Figure 1-5The device for testing the return capability of emulsion explosives includes a housing 1. A drive motor 2 is fixed inside the housing 1. A lead screw 3 is movably installed inside the housing 1. One end of the lead screw 3 is fixed to the output end of the drive motor 2. A movable plate 4 is movably installed on the surface of the lead screw 3. A mounting bracket 5 is fixed on the surface of the movable plate 4. A fixing ring 6 is movably installed inside the mounting bracket 5. A deflection cylinder 7 is fixed inside the fixing ring 6. The deflection cylinder is a transparent glass tube for easy observation of the return of explosives and for time recording. A telescopic cylinder 8 is movably installed between the deflection cylinder 7 and the upper surface of the housing 1. A detection tube 9 is installed inside the deflection cylinder 7. An angle measuring device 10 is fixed between the deflection cylinder 7 and the fixing ring 6.

[0018] The detection tube 9 includes a storage tube 91 and a transparent tube 92. A fitting ring 93, which is fitted with the deflection cylinder 7, is fixed at the connection between the storage tube 91 and the transparent tube 92. An insertion port 94 is opened on the surface of the storage tube 91, and an insertion plate is fitted inside the insertion port 94. A first ventilated end cap 96 is fitted at the end of the storage tube 91 away from the transparent tube 92, and a second ventilated end cap 97 is fitted at the end of the transparent tube 92 away from the storage tube 91. In this embodiment, the first ventilated end cap 96 and the second ventilated end cap 97 are used for air circulation in the storage tube 91 and the transparent tube 92, respectively, to prevent the sealing from affecting the flow of the emulsion explosive and causing inaccurate return measurement. This simulates the filling situation of the emulsion explosive under ventilated conditions. Alternatively, an airtight sealed end cap can be replaced to simulate the return effect of the emulsion explosive under sealed conditions.

[0019] The insert plate includes two models, namely insert plate A951 and insert plate B952. Insert plate A951 is a sealing plate to prevent emulsion explosive from flowing into transparent tube 92 during the test preparation stage. Insert plate B952 has a through hole in the center with the same inner diameter as transparent tube 92, which is used for emulsion explosive to flow from storage tube 91 into transparent tube 92.

[0020] The angle measuring device 10 includes a mounting plate 101 fixed to the side wall of the fixing ring 6 and a positioning ring 102 fitted on the surface of the deflection cylinder 7. A pointer 103 is movably mounted between the positioning ring 102 and the mounting plate 101. An angle mark 104 is engraved on the side wall of the mounting plate 101.

[0021] The telescopic cylinder 8 has a first movable connecting seat 81 and a second movable connecting seat 82 movably installed at both ends.

[0022] The surface of the deflection cylinder 7 is fixed with a fixing plate 71 for fixing to the first movable connecting seat 81. One end of the deflection cylinder 7 is provided with a vent hole for discharging gas from the detection tube 9. The other end of the deflection cylinder 7 is fixed with a flange ring 72 that mates with the detection tube 9.

[0023] When using this device, first insert plug A into socket 94, inject the emulsion explosive to be tested into storage tube 91 of detection tube 9, and install the first vent cap 96 and the second vent cap 97 on both ends of detection tube 9. Then, in conjunction with starting drive motor 2 and telescopic cylinder 8, drive deflection cylinder 7 to deflect. Specifically, starting drive motor 2 drives lead screw 3 to rotate, which in turn drives moving plate 4 to translate, thereby driving mounting bracket 5 to translate. Simultaneously, starting telescopic cylinder 8 extends and retracts, thus driving deflection cylinder 7 to deflect. When deflection cylinder 7 deflects, it drives the positioning ring 10 of angle measuring device 10. 2. When the positioning ring 102 deflects, it drives the pointer 103 to deflect synchronously. The pointer 103 is compared with the angle mark 104 on the side wall of the mounting plate 101 to obtain the deflection angle data of the deflection cylinder 7 at this time. After the tilt angle adjustment of the deflection cylinder 7 is completed, the detection tube 9 is inserted into the deflection cylinder 7. The sleeve ring 93 of the detection tube 9 is inserted into the flange ring 72 of the deflection cylinder 7. Finally, the insertion plate A951 is pulled out and the insertion plate B is quickly inserted and pulled out. The return explosive capability test can be carried out. The flow time data of the emulsion explosive in the transparent tube 92 of the detection tube 9 is recorded to determine the return explosive capability.
