Abstract
Description
Technical Field
[0001] This utility model relates to the field of emulsion explosives technology, specifically to an emulsion explosive adhesion testing device. Background Technology
[0002] Emulsion explosives are a new type of industrial explosive developed in the 1970s. Their core structure is a water-in-oil emulsion system, in which microdroplets of oxidant aqueous solution are uniformly dispersed in the oil phase through an emulsifier to form a stable explosive system. Due to their comprehensive performance advantages, emulsion explosives have become the mainstream choice in mining, engineering blasting and other fields.
[0003] Regarding the above and existing related technologies: the adhesion ability of emulsion explosives is an important performance indicator for measuring whether they are easy to fall off and can stably adhere to the borehole wall during blasting operations (such as inside the borehole), which directly affects the blasting effect and safety; since the traditional tensile test method is relatively complex and requires a lot of equipment, it is easy to have low testing efficiency; therefore, an emulsion explosive adhesion ability testing device is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An emulsion explosive adhesion testing device includes a test plate and an adjustment device. The upper surface of the test plate has a groove. The adjustment device is disposed on the surface of the test plate and includes a placement plate located directly below the test plate. Rotating columns are fixedly connected to both sides of the test plate, and the surfaces of the two rotating columns are rotatably connected to the inner wall of the placement plate. A graduated ring is fixedly connected to the surface of the placement plate, and a pointer is fixedly connected to the side wall of the test plate near the graduated ring. The pointer moves on the surface of the graduated ring. After the emulsion explosive falls off when the test plate rotates to a certain extent, the reading indicated by the pointer on the graduated ring is read, and then calculated using a formula. By setting up the placement plate, rotating columns, graduated ring, and pointer, the adhesion ability of emulsion explosives can be conveniently tested.
[0007] Preferably, a scale is fixedly connected to the surface of the scale ring. After the scale ring is set, the scale is glued to the surface of the scale ring. By setting the scale, the angle of the test plate can be easily read.
[0008] Preferably, the rotating column is threadedly connected to a turntable, which is located on one side of the scale ring. Rotating the turntable causes it to rotate on the surface of the rotating column, and the turntable presses against the side wall of the scale ring. By setting the turntable, the rotating column can be limited.
[0009] Preferably, a handle is fixedly connected to the side wall of the turntable, and a rubber ring is fixedly connected to the end of the turntable away from the handle. The turntable drives the rubber ring to rotate and move its position, and the rubber ring is pressed against the side wall of the scale ring. By setting the rubber ring, the friction between the turntable and the scale ring can be increased.
[0010] Preferably, a rotating hole is provided on the surface of the placement plate near the rotating column, and the surface of the rotating column is rotatably connected to the inner wall of the rotating hole of the placement plate. When the rotating column rotates, it rotates on the inner surface of the placement plate through the rotating hole. The opening of the rotating hole facilitates the rotation of the rotating column.
[0011] Preferably, a collection device is provided on one side of the placement plate. The collection device includes a pad, which is located on one side of the placement plate. A baffle is fixedly connected to the upper surface of the pad, and two limiting blocks are fixedly connected to the side wall of the pad. The two limiting blocks are located on both sides of the placement plate. When the emulsion explosive moves, the emulsion explosive will fall onto the surface of the pad and will be blocked by the baffle. By setting the pad, baffle and limiting blocks, the emulsion explosive can be collected conveniently.
[0012] Preferably, the surface of the placement plate is provided with positioning holes, and positioning rods are threadedly connected to the inner walls of the two limiting blocks and the inner walls of the positioning holes of the placement plate. After the limiting blocks are attached to the placement plate, the positioning rods are rotated to the inner walls of the two limiting blocks and the inner walls of the positioning holes. The position of the positioning rods can limit the position of the limiting blocks.
[0013] The advantages of this utility model are:
[0014] 1. When testing is required, this utility model places the emulsion explosive sample on the upper surface of the test plate, ensuring the emulsion explosive adheres to the groove. The test plate is then rotated, causing a rotating column to rotate within the rotating hole of the test plate. This rotation causes a pointer to move. As the emulsion explosive moves away from the groove, the pointer's position on the scale ring is read. A larger critical angle indicates stronger adhesion of the emulsion explosive. For measuring specific angles, the test plate is rotated to a suitable angle, and then the handle is rotated to rotate the turntable. The turntable moves a rubber ring, which presses against the side wall of the scale ring, allowing for testing. This device enables rapid evaluation of the emulsion explosive's adhesion to different contact materials and environments, providing intuitive results that closely reflect actual explosive loading scenarios.
[0015] 2. In this invention, after the placement plate is placed, the pad is pushed to move the limiting block. The pad and the limiting block are in contact with the placement plate. Then, the positioning rod is rotated to the inner wall of the two limiting blocks and the inner wall of the positioning hole of the placement plate. When the emulsion explosive falls, it will fall onto the upper surface of the pad and be blocked by the baffle. By setting up the whole device, the emulsion explosive can be easily collected, reducing the possibility of the emulsion explosive being contaminated by contact with other objects.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figure 1-5As shown, the emulsion explosive adhesion testing device includes a test plate 1 and an adjustment device 2. The upper surface of the test plate 1 has grooves. The adjustment device 2 is disposed on the surface of the test plate 1 and includes a placement plate 21 located directly below the test plate 1. Rotating columns 22 are fixedly connected to both sides of the test plate 1, and the surfaces of the two rotating columns 22 are rotatably connected to the inner wall of the placement plate 21. A graduated ring 23 is fixedly connected to the surface of the placement plate 21, and the side wall of the test plate 1 is positioned near the graduated ring 23. A pointer 24 is fixedly connected. During operation, the emulsion explosive is adhered to the surface of the test plate 1. Then, the test plate 1 is pushed to make the rotating column 22 and the pointer 24 rotate. The rotating column 22 rotates on the inner wall of the placement plate 21, and the pointer 24 moves on the surface of the scale ring 23. After the emulsion explosive falls off when the test plate 1 has rotated to a certain extent, the reading indicated by the pointer 24 on the scale ring 23 is read. Then, the calculation is performed by the formula. By setting the placement plate 21, rotating column 22, scale ring 23 and pointer 24, the adhesion ability of the emulsion explosive can be conveniently tested.
[0025] A scale 25 is fixedly connected to the surface of the scale ring 23; during operation, the scale 25 is attached to the surface of the scale ring 23, and the angle of the test plate 1 can be easily read by setting the scale 25.
[0026] The rotating column 22 is threadedly connected to a turntable 26, which is located on one side of the scale ring 23. During operation, after the test plate 1 is rotated to a suitable angle, the turntable 26 is rotated to make the turntable 26 rotate on the surface of the rotating column 22. The turntable 26 is pressed against the side wall of the scale ring 23. By setting the turntable 26, the rotating column 22 can be limited.
[0027] A handle 27 is fixedly connected to the side wall of the turntable 26, and a rubber ring 28 is fixedly connected to the end of the turntable 26 away from the handle 27. During operation, rotating the handle 27 causes the turntable 26 to rotate, which in turn causes the rubber ring 28 to rotate and move. The rubber ring 28 is pressed against the side wall of the scale ring 23. By setting the rubber ring 28, the friction between the turntable 26 and the scale ring 23 can be increased.
[0028] A rotating hole 29 is provided on the surface of the placement plate 21 near the rotating column 22. The surface of the rotating column 22 and the inner wall of the rotating hole 29 of the placement plate 21 are rotatably connected. During operation, the rotating column 22 rotates on the inner surface of the placement plate 21 through the rotating hole 29. The opening of the rotating hole 29 facilitates the rotation of the rotating column 22.
[0029] A collection device 3 is provided on one side of the placement plate 21. The collection device 3 includes a pad 31, which is located on one side of the placement plate 21. A baffle 32 is fixedly connected to the upper surface of the pad 31. Two limiting blocks 33 are fixedly connected to the side wall of the pad 31, and the two limiting blocks 33 are located on both sides of the placement plate 21 respectively. During operation, pushing the pad 31 causes the pad 31 to move the limiting blocks 33 and the baffle 32. The limiting blocks 33 move to the side wall of the placement plate 21. When the emulsion explosive moves, the emulsion explosive will fall onto the surface of the pad 31 and will be blocked by the baffle 32. By setting the pad 31, the baffle 32 and the limiting blocks 33, the emulsion explosive can be collected conveniently.
[0030] The surface of the placement plate 21 is provided with positioning holes 35, and positioning rods 34 are threadedly connected to the inner walls of the two limiting blocks 33 and the inner walls of the positioning holes 35 of the placement plate 21. During operation, the positioning rods 34 are rotated to the inner walls of the two limiting blocks 33 and the inner walls of the positioning holes 35, and the position of the positioning rods 34 can limit the position of the limiting blocks 33.
[0031] Working principle: When testing is required, the emulsion explosive sample is placed on the upper surface of test plate 1, ensuring it adheres to the groove 4. Test plate 1 is then rotated, causing the rotating column 22 to rotate. The rotating column 22 rotates within the rotating hole 29 of the placement plate 21. The rotation of test plate 1 causes the pointer 24 to move. As the emulsion explosive moves away from the groove 4, the position of pointer 24 on the scale 25 of the scale ring 23 is read. A larger critical angle indicates stronger adhesion of the emulsion explosive. When measuring a specific angle, test plate 1 is rotated to a suitable angle, and then the handle 27 is rotated, causing the turntable 26 to rotate. The turntable 26 moves the rubber ring 28, which presses against the side wall of the scale ring 23. Afterwards, testing was conducted. By setting up the entire device, the adhesion ability of emulsion explosives could be tested. Sunlight quickly assessed the adhesion ability of emulsion explosives under different contact materials and environments, and the results were intuitive and close to the actual charging scenario. After the placement plate 21 was placed, the pad 31 was pushed to move the limiting block 33. The pad 31 and the limiting block 33 were attached to the placement plate 21. Then, the positioning rod 34 was rotated to the inner wall of the two limiting blocks 33 and the inner wall of the positioning hole 35 of the placement plate 21. When the emulsion explosive fell, it fell onto the upper surface of the pad 31 and was blocked by the baffle 32. By setting up the entire device, the emulsion explosive could be easily collected, reducing the possibility of the emulsion explosive being contaminated by contact with other objects.
