Description

Technical Field

[0001] This utility model relates to the field of emulsified ammonium nitrate explosives, specifically a liquid ammonium nitrate storage and metering device for emulsified ammonium nitrate explosives. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives formed by uniformly dispersing droplets of an oxidizing agent salt solution in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, using an emulsifier. Emulsion explosives have high density, high detonation velocity, high brisaccharidism, good water resistance, small critical diameter, and good initiation sensitivity. In small-diameter cases, they exhibit detonator sensitivity. They typically do not use pyrotechnic explosives as sensitizers, making production safe and less polluting. Currently, many varieties have been developed, including open-pit emulsion explosives for open-pit mines, rock-type emulsion explosives for blasting medium-hard rocks, permissible emulsion explosives for underground coal mines, and small-diameter, low-detonation-velocity emulsion explosives for smooth blasting.

[0003] In the production of existing emulsified ammonium nitrate explosives, a liquid ammonium nitrate storage and metering device is generally required to store the liquid ammonium nitrate.

[0004] Most existing liquid ammonium nitrate storage and metering devices for emulsified ammonium nitrate explosives lack internal buffering mechanisms. This means that when liquid ammonium nitrate is injected into the device, the impact force cannot be buffered, leading to fluctuations in the liquid level and affecting the accuracy of the metering.

[0005] Therefore, this invention provides a liquid ammonium nitrate storage and metering device for emulsified ammonium nitrate explosives to solve the above problems. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: a liquid ammonium nitrate storage and metering device for emulsified ammonium nitrate explosive, comprising a mounting base plate, a storage tank fixedly connected to the upper surface of the mounting base plate, and a feed pipe fixedly connected to one side of the upper surface of the storage tank. The storage tank is equipped with a stirring mechanism inside, a buffer mechanism is installed on the surface of the stirring mechanism, and a metering mechanism is installed on the surface of the storage tank.

[0010] The buffer mechanism includes an isolation plate fitted inside the stirring mechanism. The isolation plate is fixedly connected to the inside of the storage tank. A sealing plate is attached to the upper surface of the isolation plate. A flip plate is fixedly connected to the upper surface of the sealing plate. A rotating rod is fixedly connected to the surface of the flip plate. The rotating rod is rotatably connected to the inside of the storage tank through a bearing seat.

[0012] As a preferred technical solution of this application, the guiding mechanism further includes a feed trough arranged in a ring array on one side of the upper surface of the isolation plate, and a guide plate fixedly connected to one side of the lower surface of the isolation plate near the guide pipe. The guide plate corresponds to the feed trough and is in contact with the guide pipe.

[0016] (3) Beneficial effects

[0017] By incorporating a storage tank, a stirring mechanism, and a buffer mechanism, when liquid ammonium nitrate is injected into the storage tank through the feed pipe, it impacts the surface of the tilting plate, causing the tilting plate to rotate and the sealing plate to move. This allows the connecting channel to leak out, enabling the liquid ammonium nitrate to enter the guide pipe through the connecting channel and then into the storage tank for storage. This avoids the problem of liquid ammonium nitrate directly entering the storage tank, which could cause fluctuations in the liquid ammonium nitrate level inside the tank and affect the accuracy of the measurement.

[0018] By incorporating storage tanks, buffer mechanisms, and metering mechanisms, the drive motor is simultaneously activated during the storage of liquid ammonium nitrate. This causes the stirring rod to rotate, driving the stirring blades and arc-shaped rod to agitate the liquid ammonium nitrate inside the storage tank. This prevents temperature differences between the liquid ammonium nitrate and ensures that the temperature is monitored. A temperature monitoring device is also installed to prevent the liquid ammonium nitrate from overheating and crystallizing if the temperature is too low. An electromagnetic flow meter is used to precisely control the flow rate of the liquid ammonium nitrate. Attached Figure Description

[0025] 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 protection scope of the present utility model.

[0026] This invention provides a device for storing and metering liquid ammonium nitrate in emulsified ammonium nitrate explosives, such as... Figure 1-Figure 4 As shown, a liquid ammonium nitrate storage and metering device for emulsified ammonium nitrate explosive includes a mounting base plate 1, a storage tank 2 fixedly connected to the upper surface of the mounting base plate 1, and a feed pipe fixedly connected to one side of the upper surface of the storage tank 2. A stirring mechanism is installed inside the storage tank 2. The stirring mechanism includes a stirring rod 12 rotatably connected to the inside of the storage tank 2. Stirring blades 13 are fixedly connected to the surface of the stirring rod 12 in a ring array. One end of the stirring rod 12 is fixedly connected to a drive motor 14 whose output end is fixedly connected to the stirring rod 12. When the drive motor 14 is started, its output end drives the stirring rod 12 to rotate inside the storage tank 2, so that the stirring blades 13 and the arc rod rotate inside the storage tank 2, stirring the liquid ammonium nitrate inside the storage tank 2, making the temperature of the liquid ammonium nitrate more stable and avoiding temperature differences between the liquid ammonium nitrate.

[0027] The drive motor 14 is fixedly connected to the upper surface of the storage tank 2. The bottom of the surface of the stirring rod 12 is fixedly connected to an arc-shaped rod corresponding to the storage tank 2. A buffer mechanism is installed on the surface of the stirring mechanism. The buffer mechanism includes an isolation plate 3 sleeved inside the stirring mechanism. The isolation plate 3 is fixedly connected to the inside of the storage tank 2. A sealing plate 4 is attached to the upper surface of the isolation plate 3. A flip plate 5 is fixedly connected to the upper surface of the sealing plate 4. A rotating rod 6 is fixedly connected to the surface of the flip plate 5. The rotating rod 6 is rotatably connected to the inside of the storage tank 2 through a bearing seat. Buffer springs 7 are fixedly connected to both edges on one side of the flip plate 5. Liquid ammonium nitrate is injected into the inside of the storage tank 2 through the feed pipe, so that it impacts the surface of the flip plate 5. The impact force is buffered by the elastic force of the buffer springs 7.

[0028] The buffer spring 7 is fixedly connected to the isolation plate 3. The surface of the isolation plate 3 has a path array of connecting grooves 8, which correspond to the sealing plate 4. A guide mechanism is installed on the lower surface of the isolation plate 3. The guide mechanism includes a flow guide pipe 9 fixedly connected to one side of the lower surface of the isolation plate 3 in a path array. Several flow guide pipes 9 are connected to the corresponding connecting grooves 8. The flow guide pipes 9 are fixedly connected to the inside of the storage tank 2. The impact force drives the flip plate 5 to rotate inside the storage tank 2 through the rotating rod 6, thereby causing the flip plate 5 to drive the sealing plate 4 to slide on the surface of the isolation plate 3, so that the sealing plate 4 no longer seals the connecting grooves 8, thereby allowing liquid ammonium nitrate to enter the interior of the flow guide pipes 9 through the connecting grooves 8, and allowing liquid ammonium nitrate to enter the interior of the storage tank 2 through the flow guide pipes 9.

[0029] The guide pipe 9 is connected to the storage tank 2. The guiding mechanism also includes a feed chute 10 arranged in a ring array on one side of the upper surface of the isolation plate 3. A guide plate 11 is fixedly connected to one side of the lower surface of the isolation plate 3 near the guide pipe 9. The guide plate 11 corresponds to the feed chute 10 and is in contact with the guide pipe 9. Through the setting of the feed chute 10, the liquid ammonium nitrate passes through the isolation plate 3 and falls on the surface of the guide plate 11, so that the liquid ammonium nitrate can enter the interior of the storage tank 2 more quickly. This avoids the liquid ammonium nitrate being directly injected into the interior of the storage tank 2, which would cause fluctuations in the liquid level inside the storage tank 2 and affect the accuracy of the measurement.

[0030] A metering mechanism is installed on the surface of storage tank 2. The metering mechanism includes an electromagnetic flowmeter 15 fixedly connected to one side of storage tank 2. The electromagnetic flowmeter 15 is used to precisely control the flow rate of liquid ammonium nitrate. A temperature monitor 16 is fixedly connected to the surface of storage tank 2. A detection head 17 is fixedly connected to the surface of temperature monitor 16 via a wire. The temperature monitor 16 is used to monitor the temperature of liquid ammonium nitrate, preventing the liquid ammonium nitrate from becoming too hot and causing danger, and preventing the liquid ammonium nitrate from crystallizing if the temperature is too low. The detection head 17 is installed inside storage tank 2. A hollow box 18 is fitted onto the surface of storage tank 2. The hollow box 18 has an insulation layer inside. A ladder 19 is fixedly connected to one side of storage tank 2. Observation windows are provided on the surface of storage tank 2 and hollow box 18.

[0031] Specifically, when this emulsified ammonium nitrate explosive liquid ammonium nitrate storage and metering device is in use: liquid ammonium nitrate is injected into the storage tank 2 through the feed pipe, causing it to impact the surface of the tilting plate 5. The impact force is buffered by the spring force of the buffer spring 7. At the same time, the impact force drives the tilting plate 5 to rotate inside the storage tank 2 via the rotating rod 6. This causes the tilting plate 5 to drive the sealing plate 4 to slide on the surface of the isolation plate 3, so that the sealing plate 4 no longer seals the connecting groove 8. This allows the liquid ammonium nitrate to enter the guide pipe 9 through the connecting groove 8 and into the storage tank 2. Furthermore, the feed trough 10 allows the liquid ammonium nitrate to pass through the isolation plate 3 and fall onto the surface of the guide plate 11. This allows the liquid ammonium nitrate to enter the storage tank 2 more quickly, avoiding direct injection of liquid ammonium nitrate into the storage tank 2, which would cause fluctuations in the liquid level inside the storage tank 2 and affect the metering accuracy.

[0032] Simultaneously, the drive motor 14 is started, causing its output end to drive the stirring rod 12 to rotate inside the storage tank 2. This causes the stirring blade 13 and the arc-shaped rod to rotate inside the storage tank 2, stirring the liquid ammonium nitrate inside the storage tank 2. This makes the temperature of the liquid ammonium nitrate more stable and avoids temperature differences between liquid ammonium nitrate. The temperature monitoring instrument 16 is set to monitor the temperature of the liquid ammonium nitrate, preventing the liquid ammonium nitrate from becoming too hot and causing danger, and preventing the liquid ammonium nitrate from becoming too cold and causing crystallization. The electromagnetic flow meter 15 is set to precisely control the flow rate of the liquid ammonium nitrate.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
