Description

Technical Field

[0001] This utility model relates to the field of explosives production technology, and more specifically, to an emulsification device for emulsified explosives. Background Technology

[0002] Emulsion explosives utilize the action of emulsifiers to uniformly disperse microdroplets of oxidant salt aqueous solutions in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil (W / O) emulsion explosive. The production process of emulsion explosives consists of three steps: emulsification, concentration, and drying. During emulsification, fuel oil, emulsifiers, nitrogen, and other additives are added to a reaction vessel in a certain proportion, stirred, and heated to form a stable emulsion.

[0003] Existing emulsion explosive devices have some shortcomings in terms of technology, safety performance, production efficiency and cost; after long-term operation, the emulsification effect may be unstable due to wear or aging of internal components, resulting in inconsistent product quality; the internal components are complex and difficult to maintain; after long-term operation, emulsion devices are prone to the accumulation of material residue and dirt, making cleaning and maintenance difficult.

[0004] For example, Chinese patent CN221988444U discloses an emulsified explosive device. By using an emulsification heating component in conjunction with a stirring mechanism within the emulsification reactor, the emulsification efficiency of the explosive raw materials can be improved. Furthermore, the emulsification heating component has a simple structure, is easy to disassemble, and facilitates maintenance and replacement, making it more practical. However, the stirring mechanism and blades are fixed to the tank, which greatly hinders subsequent cleaning work and causes inconvenience in the subsequent maintenance and upkeep of the device, thus exhibiting certain technical defects.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an emulsification device for emulsified explosives to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An emulsification device for emulsified explosives includes a workbench, an emulsification tank at the bottom of one side of the workbench, and a hydraulic lifting rod at the top of the other side of the workbench. A cover plate is provided at the top of the emulsification tank, and a stirring mechanism is installed inside the tank. Preheating boxes are located on both sides of the top of the cover plate, and an installation box is located at the top of the cover plate between the two preheating boxes. A drive mechanism that cooperates with the stirring mechanism is installed inside the installation box. An installation crossbar that cooperates with the installation box is provided at the top of the hydraulic lifting rod.

[0009] Furthermore, in order to heat the emulsified material of the explosive inside the emulsification tank and improve the emulsification efficiency, the emulsification tank has a double-layer structure, and several heating rods arranged in a ring at equal intervals are set in the interlayer of the emulsification tank; a discharge port is set at the bottom of the emulsification tank.

[0010] Furthermore, in order to utilize the relative rotation between the outer cylinder and the inner shaft to achieve the relative movement of the two sets of stirring blades, thereby further improving the stirring efficiency of explosive emulsification, and to clean the inner wall of the emulsification tank in real time by using scraper rods, the stirring mechanism includes an outer cylinder inserted at the center of the cover plate, an inner shaft inserted inside the circumference of the outer cylinder, scraper rods on both sides of the bottom end of the outer cylinder, multiple sets of vertically arranged fixed seats on the inner side of the scraper rods and the outer side of the circumference of the inner shaft, a connecting rod between two fixed seats in the same set, and several equidistantly arranged positioning blocks vertically arranged on the connecting rod, with stirring blades on one side of each positioning block.

[0011] Furthermore, in order to enable independent disassembly of the stirring blades, damaged stirring blades can be replaced individually during maintenance. The positioning block has a threaded hole on the side near the stirring blade, and a threaded post that mates with the threaded hole is provided on one side of the stirring blade.

[0012] Furthermore, in order to utilize the driven bevel gear and the driving bevel gear arranged at the top and bottom to realize the relative rotation between the outer cylinder and the inner shaft, thereby driving the stirring mechanism to stir and emulsify the material, the driving mechanism includes a driven bevel gear arranged at the top of the outer cylinder and a driving bevel gear arranged at the top of the inner shaft. A linkage bevel gear that cooperates with the driven bevel gear and the driving bevel gear is arranged on one side inside the mounting box, and a drive motor connected to the inner shaft is arranged at the top of the mounting box.

[0013] Furthermore, in order to utilize the air blowing capacity of the cleaning fan to clean the impurities remaining on the stirring blades and improve the cleaning efficiency of the device, cleaning fans are installed on both sides of the bottom end of the cover plate, and the cleaning fans are located inside the emulsification tank.

[0014] Furthermore, in order to connect the various electrical components and enable electric control, a control panel is installed on one side of the workbench. The control panel is electrically connected to the hydraulic lifting rod, preheating box, drive motor, heating rod and cleaning fan.

[0015] The beneficial effects of this utility model are as follows:

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, an emulsification device for emulsified explosives is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, an emulsification device for emulsified explosives according to an embodiment of the present invention includes a workbench 1, an emulsification tank 2 is provided at the bottom of one side of the workbench 1, and a hydraulic lifting rod 3 is provided at the top of the other side of the workbench 1; a cover plate 4 is provided at the top of the emulsification tank 2, a stirring mechanism 5 is provided inside the emulsification tank 2, preheating boxes 6 are provided on both sides of the top of the cover plate 4, and an installation box 7 is provided at the top of the cover plate 4 and between the two preheating boxes 6, and a drive mechanism 8 cooperating with the stirring mechanism 5 is provided inside the installation box 7; an installation crossbar 9 cooperating with the installation box 7 is provided at the top of the hydraulic lifting rod 3.

[0029] With the help of the above technical solution, by setting up a hydraulic lifting rod 3, the top cover plate 4 of the emulsion tank 2 can be automatically lifted and lowered. During the lifting and lowering process, the stirring mechanism 5 inside the emulsion tank 2 can be cleaned, maintained or replaced, which can effectively improve the cleaning efficiency of the device and reduce maintenance costs. In addition, during use, by adding emulsion explosive raw materials into the emulsion tank 2, the stirring mechanism 5, which can rotate synchronously inside and outside, can greatly improve the stirring efficiency of the emulsion explosive and enhance the emulsification effect of the emulsion explosive.

[0030] In one embodiment, the emulsifying tank 2 has a double-layer structure, and a number of heating rods 10 arranged in a ring at equal intervals are provided in the interlayer of the emulsifying tank 2; the bottom end of the emulsifying tank 2 is provided with a discharge port 11, so as to heat the emulsified material of the explosive inside the emulsifying tank 2 and improve the emulsification efficiency.

[0031] In one embodiment, the stirring mechanism 5 includes an outer cylinder 501 inserted at the center of the cover plate 4, an inner shaft 502 inserted on the inner circumference of the outer cylinder 501, and scraper rods 503 on both sides of the bottom end of the outer cylinder 501. Multiple sets of vertically arranged fixed seats 504 are arranged on the inner side of the scraper rods 503 and the outer circumference of the inner shaft 502. A connecting rod 505 is arranged between two fixed seats 504 in the same set. Several equidistantly arranged positioning blocks 506 are arranged vertically on the connecting rods 505. A stirring blade 507 is arranged on one side of the positioning block 506. Thus, the outer cylinder 501 and the inner shaft 502 can rotate relative to each other, realizing the relative movement of the two sets of stirring blades 507, further improving the stirring efficiency of explosive emulsification, and the inner wall of the emulsification tank 2 can be cleaned in real time by the scraper rods 503.

[0032] The working principle of the stirring mechanism 5: The outer cylinder 501 drives the two scraper rods 503 (L-shaped structure) to rotate, and the inner shaft 502 drives the outer stirring blades 507 to rotate in the opposite direction. Since the stirring blades 507 on the inner side of the outer cylinder 501 and the stirring blades 507 on the outer side of the inner shaft 502 are arranged alternately, the stirring efficiency can be improved. Furthermore, the connecting rod 505 can be fixed between the upper and lower fixed seats 504 using bolts, and the stirring blades 507 on the connecting rod 505 are connected using threaded posts 509.

[0033] In one embodiment, the positioning block 506 has a threaded hole 508 on the side near the stirring blade 507, and a threaded post 509 that mates with the threaded hole 508 is provided on the side of the stirring blade 507, thereby enabling the independent disassembly of the stirring blade 507 and allowing damaged stirring blades 507 to be replaced individually during maintenance.

[0034] In one embodiment, the drive mechanism 8 includes a driven bevel gear 801 disposed at the top of the outer cylinder 501 and a drive bevel gear 802 disposed at the top of the inner shaft 502. A linkage bevel gear 803 that cooperates with the driven bevel gear 801 and the drive bevel gear 802 is disposed on one side inside the mounting box 7. A drive motor 804 connected to the inner shaft 502 is disposed at the top of the mounting box 7. Thus, the relative rotation between the outer cylinder 501 and the inner shaft 502 can be achieved by using the driven bevel gear 801 and the drive bevel gear 802 disposed vertically, thereby driving the stirring mechanism 5 to stir and emulsify the material.

[0035] The working principle of the drive mechanism 8 is as follows: the drive motor 804 drives the drive bevel gear 802 to rotate, and the drive bevel gear 802 drives the driven bevel gear 801 to rotate through the linkage bevel gear 803. Since the drive bevel gear 802 is connected to the inner shaft 502 and the driven bevel gear 801 is connected to the outer cylinder 501, the relative rotation between the outer cylinder 501 and the inner shaft 502 can be realized.

[0036] In one embodiment, for the cover plate 4, cleaning fans 12 are provided on both sides of the bottom end of the cover plate 4. The cleaning fans 12 are located inside the emulsification tank 2, so that the blowing capacity of the cleaning fans 12 can be used to clean the impurities remaining on the stirring blades 507, thereby improving the cleaning efficiency of the device.

[0037] In one embodiment, for the workbench 1, a control panel 13 is provided on one side of the workbench 1. The control panel 13 is electrically connected to the hydraulic lifting rod 3, the preheating box 6, the drive motor 804, the heating rod 10 and the cleaning fan 12, thereby realizing the connection of various electrical components and performing electric control.

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] In practical applications, the raw materials for the emulsion explosive are added to the corresponding preheating box 6 for preheating. The preheating box 6 is equipped with independent heating devices to control the heating to a specified temperature. After preheating, the raw materials are fed into the emulsion tank 2 through internal pipes. Once in the emulsion tank 2, the raw materials are stirred and emulsified using the stirring mechanism 5 until stirring is complete, at which point they are discharged through the discharge port 12. During maintenance and cleaning, the hydraulic lifting rod 3 can be driven to move the cover plate 4 upwards, completely detaching it from the emulsion tank 2. Operators can then clean or replace the stirring blades 507 inside the stirring mechanism 5 to ensure it remains in good working order.

[0040] In summary, by utilizing the above-mentioned technical solution of this utility model, the hydraulic lifting rod 3 can automatically lift and lower the top cover plate 4 of the emulsification tank 2. During the lifting and lowering process, the stirring mechanism 5 inside the emulsification tank 2 can be cleaned, maintained, or replaced, effectively improving the cleaning efficiency of the device and reducing maintenance costs. Furthermore, during use, by adding emulsified explosive raw materials into the emulsification tank 2, the stirring efficiency of the emulsified explosive can be greatly improved by utilizing the stirring mechanism 5, which can rotate synchronously inside and outside, thus enhancing the emulsification effect. By setting an outer cylinder 501, an inner shaft 502, a connecting rod 503, and multiple sets of stirring blades 507 inside the stirring mechanism 5, the relative movement of the inner and outer sets of stirring blades 507 can be achieved, further improving the stirring efficiency of explosive emulsification. Moreover, the scraper rod 503 cleans the inner wall of the emulsification tank 2 in real time, further improving emulsification efficiency. By setting up a cleaning fan 12, the air blowing capacity of the cleaning fan 12 can be used to clean the impurities remaining on the stirring blades 507, thereby improving the cleaning efficiency of the device. At the same time, by setting up a preheating box 6, the emulsified explosive material can be preheated in advance, so that it maintains the same temperature after entering the emulsification tank 2, thereby enhancing the emulsification effect.
