Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to a field mixing emulsion explosives production device. Background Technology

[0002] The on-site mixing emulsion explosives truck is an integrated equipment that combines the transportation of raw materials and semi-finished products of explosives, blasting, on-site mixing, and loading. It mainly consists of a truck chassis, power output system, hydraulic system, electrical control system, fuel (oil phase) system, emulsification system, water and air cleaning system, dry material batching system, water heating system, and trace element addition system. It is suitable for water-bearing blast hole operations in open-pit mines.

[0003] Chinese patent CN212058506U discloses a lightweight downhole on-site mixing and loading vehicle for emulsion explosives. It utilizes a pumping system to deliver a latex matrix and catalyst to a catalytic mixer for latex matrix catalysis. The sensitizer is then delivered via a pumping system to a sensitizing water ring device. The catalyzed latex matrix is ​​then mixed with the sensitizer in the sensitizing water ring device and discharged, forming emulsion explosives which are then loaded into boreholes. Existing catalysts are generally citric acid, and sensitizers are generally sodium nitrite solution. When sodium nitrite solution mixes with acidic solutions, a chemical reaction easily occurs, producing nitrogen oxide gases harmful to humans. The mixer in the aforementioned patent lacks nitrogen oxide gas purification equipment, which could expose workers to nitrogen oxide gases during the production of emulsion explosives, posing a safety hazard.

[0004] Therefore, there is an urgent need to redesign a new on-site mixing emulsion explosive production unit to solve the above problems. Utility Model Content

Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] Please see Figures 1 to 7 The present invention provides a field mixing emulsion explosive production device, including but not limited to a mixer, which is used to mix the catalyzed latex matrix and the sensitizer.

[0035] Preferably, the mixer is a commercially available mixer.

[0036] The mixer is equipped with a sensor for monitoring the concentration of nitrogen oxides. A purifier is installed on one side of the mixer. If the sensor detects that the concentration of nitrogen oxide gas in the mixer is too high, the purifier is needed to purify the nitrogen oxide gas.

[0037] Please see Figures 2 to 7 The purifier includes a purification box 1, an air pump 2, a purification liquid 3, and a purification component 4.

[0038] The purification chamber 1 is equipped with an adsorption chamber 101, a storage chamber 102, and a purification chamber 103. The adsorption chamber 101 is used to install the air pump 2, the storage chamber 102 is used to store the air pump 2, and the purification chamber 103 is used to install the purification component 4.

[0039] In addition, the bottom wall of the storage chamber 102 is provided with several leakage holes 1021. The storage chamber 102 is connected to the purification chamber 103 through the leakage holes 1021. When there is purification liquid 3 in the storage chamber 102, the purification liquid 3 in the storage chamber 102 can enter the purification chamber 103 through the leakage holes 1021. With the help of the purification component 4, the nitrogen oxide gas can be purified, so that the nitrogen oxide gas is less likely to cause harm to the health of the staff.

[0040] Preferably, the leakage hole 1021 is a capillary hole, which allows the purification liquid 3 in the storage cavity 102 to drip slowly, making it less likely to waste the purification liquid 3.

[0041] Specifically, the purification chamber 1 is also provided with a waste liquid collection chamber. The bottom wall of the purification chamber 103 is provided with several through holes 1031. The purification chamber 103 is connected to the waste liquid collection chamber through the through holes 1031. The purification liquid 3 used in the purification chamber 103 can be collected in the waste liquid collection chamber through the through holes 1031.

[0042] In addition, the outer wall of the purification box 1 is equipped with a drain pipe, which is connected to the waste liquid collection chamber and is used to discharge the purification liquid 3 in the waste liquid collection chamber.

[0043] Please see Figures 2 to 7 The purification chamber 1 has an air outlet 104 on its side wall, and the purification chamber 103 is connected to the outside through the air outlet 104. The purified gas in the purification chamber 103 is finally discharged from the purification chamber 1 through the air outlet 104.

[0044] The side wall of the purification box 1 is hinged to a cover door 105, which corresponds to the purification component 4, making it convenient to maintain and replace the purification curtain 405.

[0045] In addition, the side wall of the purification chamber 1 is also equipped with an observation plate and a replenishment tube. The capacity of the purification liquid 3 in the storage chamber 102 can be observed through the observation plate, and replenishment can be made in a timely manner through the replenishment tube.

[0046] Please see Figures 2 to 7 The suction pump 2 is installed inside the adsorption chamber 101, with its suction end located inside the mixer and its outlet end located inside the purification chamber 103. When the suction pump 2 is running, it can draw in the nitrogen oxide gas from the mixer and transport the nitrogen oxide gas to the purification chamber 103.

[0047] Preferably, the vacuum pump 2 is a VCH1028 high negative pressure micro vacuum pump.

[0048] The exhaust end of the air pump 2 is located inside the purification chamber 103 and is connected to an expansion hood 201. The expansion hood 201 corresponds to the purification component 4, so that the nitrogen oxide gas drawn by the air pump 2 can fully contact the purification curtain 405 to purify the nitrogen oxide gas.

[0049] Please see Figures 2 to 7The purification liquid 3 is located within the storage chamber 102. Purification liquid 3 is a commercially available composite bio-enzyme treatment agent. Bio-enzymes possess high selectivity and catalytic efficiency, enabling catalytic reactions to occur at room temperature and pressure, without the need for complex conditions such as high temperature and high pressure. Compared to traditional physicochemical methods, the bio-enzyme treatment agent can decompose nitrogen oxides more efficiently. The composite bio-treatment agent is a natural and harmless product that will not cause secondary pollution to the environment or release toxic or harmful gases during use.

[0050] Please see Figures 2 to 7 The purification component 4 is installed inside the purification chamber 103. The purification component 4 and the purification liquid 3 work together to purify nitrogen oxide gas.

[0051] The purification component 4 includes a pair of fixing plates 401, which contact the side wall of the purification chamber 103. Two first collection slots 402 and two second collection slots 403 are fixedly connected between the pair of fixing plates 401, with the first collection slots 402 and second collection slots 403 corresponding to each other. Figure 5 As shown, the first collection tank 402 and the second collection tank 403 are used to fix the fixing frame 404 and the purification curtain 405. At the same time, the purification liquid 3 dripping through the leakage hole 1021 will fall onto the first collection tank 402 and the second collection tank 403, and finally fall onto the purification curtain 405 to humidify the purification curtain 405. When the nitrogen oxide gas passes through the humidified purification curtain 405, the nitrogen oxide gas can be purified.

[0052] In addition, the first collection tank 402 and the second collection tank 403 cover the leakage hole 1021. The purification liquid 3 dripping through the leakage hole 1021 will fall onto the first collection tank 402 or the second collection tank 403, and then moisten the purification curtain 405 through the gap between the first collection tank 402 and the second collection tank 403. When the nitrogen gas passes through the moistened purification curtain 405, the nitrogen gas can be purified.

[0053] Specifically, a fixing frame 404 is slidably provided between the first collection tank 402 and the second collection tank 403, and a purification curtain 405 is installed on the fixing frame 404. The purification liquid 3 on the first collection tank 402 or the second collection tank 403 will moisten the purification curtain 405 through the gap, and when the nitrogen oxide gas passes through the moistened purification curtain 405, it can be purified.

[0054] When the purification curtain 405 needs to be replaced, first drain the purification liquid 3 from the storage chamber 102, then remove the fixing frame 404 from between the first collection tank 402 and the second collection tank 403, and the purification curtain 405 can be replaced.

[0055] In addition, the mounting bracket 404 contacts the side wall of the mounting plate 401, which allows the nitrogen oxide gas to be fully purified and improves the purification effect of the nitrogen oxide gas.

[0056] Please see Figures 2 to 7 Several support columns 406 are connected between the fixing frame 404 and the first collection tank 402 and the second collection tank 403 to fix the fixing frame 404 and the purification curtain 405, so as to ensure the purification effect of the humidified purification curtain 405 on the nitrogen gas.

[0057] Preferably, the support column 406 is made of rubber. The rubber support column 406 can fix the fixing frame 404 and the purification curtain 405, so that the purification curtain 405 is in a vertical state, so as to wet the purification liquid 3, and at the same time, it can also ensure the purification effect of the wetted purification curtain 405 on nitrogen gas.

[0058] A pair of liquid-blocking strips 407 are fixedly connected between the pair of fixed plates 401. The purification curtain 405 and the through hole 1031 are both located between the pair of liquid-blocking strips 407. The liquid-blocking strips 407 can block liquid, so that the purification liquid 3 dripping from the first collection tank 402, the second collection tank 403, or the purification curtain 405 does not flow around, so that it can enter the waste liquid collection chamber through the through hole 1031.

[0059] In addition, an activated carbon layer 408 and a molecular sieve 409 are installed in the purification chamber 103. The activated carbon layer 408 is located on the side of the purification curtain 405 away from the gas expansion hood 201. Both the activated carbon layer 408 and the molecular sieve 409 are used to filter the purified gas again, thereby improving the gas purification effect.

[0060] In practical use, when the sensor detects a high concentration of nitrogen gas in the mixer, the vacuum pump 2 will operate. The vacuum pump 2 can extract the nitrogen gas in the mixer and deliver the nitrogen gas to the purification chamber 103.

[0061] Nitrogen oxide gas in the purification chamber 103 passes through a pair of humidified purification curtains 405, which purify the gas. At the same time, the gas passes through an activated carbon layer 408 and a molecular sieve 409 for further filtration. Finally, the gas is discharged from the purification chamber 1 through the outlet 104, ensuring that the discharged gas does not contain nitrogen oxide gas, thereby reducing the impact of nitrogen oxide gas on the health of workers and ensuring the working environment of workers.

[0062] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
