Description

Technical Field

[0001] This utility model relates to the technical field of explosives processing equipment, and in particular to an explosives mixing device that can be quickly disassembled. Background Technology

[0002] In the production of explosives, the mixing process is the core step that determines the explosive performance, storage stability, and safety of use. This process requires the precise proportioning of oxidizers, fuels, sensitizers, and additives, and the uniform dispersion under strict control of temperature, pressure, and mixing intensity, ultimately forming an explosive matrix with uniform physicochemical properties. Existing explosive mixing devices have the following shortcomings.

[0003] 1. Mechanical mixing devices have mixing dead zones: The mixing paddles of traditional vertical mixing mixers are mostly anchor or paddle structures, which can only achieve radial mixing. The cylinder wall and the root of the mixing shaft are prone to forming a "static zone". The material in this zone cannot participate in effective mixing, resulting in excessively high local oxidizer content or fuel enrichment in the finished explosive, causing detonation velocity fluctuations.

[0004] 2. Static mixing devices have poor adaptability and are prone to clogging: Static mixers (such as SV type and SX type) achieve material division and recombination through mixing elements fixed in the pipeline. Although there are no moving parts, they are only suitable for materials with low viscosity and no solid particles. They are not suitable for mixing explosives such as RDX and octogen.

[0005] 3. The mixing device is not easy to clean: Both mechanical stirring and static mixing devices are not easy to clean and cannot be used for switching between different explosives. The cleaning time efficiency and effect are poor.

[0006] To address the aforementioned problems, this utility model provides an explosive mixing device that is easy to disassemble and clean, and allows for mixing without any blind spots. Summary of the Invention

[0007] The purpose of this invention is to provide a quick-disassembly explosive mixing device.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A quick-disassembly explosive mixing device includes a frame, mixing shafts, and a mixing container.

The shoulder of the feed inlet of the mixing tank is provided with a threaded hole corresponding to the position of the countersunk hole. After the cover plate is installed on the side wall of the mixing tank, the side wall of the mixing tank forms a complete cylinder.

[0010] Furthermore, the transmission mechanism includes a driving gear and two driven gears with the same number of teeth. The driving gear is mounted on the motor shaft of the mixing motor, and the two driven gears are respectively mounted on the shaft ends of the two mixing shafts. The driving gear meshes with the two driven gears for transmission.

[0011] Furthermore, the two ends of the mixing shaft are provided with limiting shoulders with a diameter larger than that of the working section, and the limiting shoulders and the working section of the mixing shaft are connected by a conical transition.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] like Figure 1-8As shown, a quick-disassembly explosive mixing device includes a frame 1, mixing shafts 2, and a mixing container 3. Two mixing shafts 2 are mounted parallel to each other on the frame at the same horizontal plane via bearings. The shaft ends of the two mixing shafts 2 are connected to a mixing motor 4 on the frame 1 via a transmission mechanism. The mixing motor 4 drives the two mixing shafts 2 to rotate in the same direction via the transmission mechanism. The outer side of the mixing shafts 2 is covered with an electrostatic conductive layer 34. The mixing container 3 is placed horizontally on the two mixing shafts 2. A mixing prism 26 made of flexible material is installed inside the mixing chamber of the mixing container 3. The two ends of the mixing prism 26 are... Two circular rings are connected by multiple evenly distributed ribs 27. Each ring is also provided with a cross-shaped reinforcing rib 31. The diameter and length of the mixing prism 26 are respectively 2-5 mm larger than the diameter and length of the mixing chamber of the mixing tank 3, so that the two end rings and ribs 27 are in close contact with the side wall of the mixing chamber. One or more adjacent ribs 27 are provided with multiple evenly distributed mounting ball holes 28. Each mounting ball hole 28 is equipped with a counterweight ball 29. The number of ribs with counterweight balls 29 is less than half of the total number, so that the ribs 27 with counterweight balls 29 are supported by their own weight. The mixing chamber is kept at the bottom; the mixing tank 3 has placement shafts 22 at both ends, and the outer ends of the placement shafts 22 are provided with limiting blocks 23. The limiting blocks 23 are provided with multiple evenly distributed lifting holes 30; the upper end of the frame 1 is equipped with a movable crossbeam 7 and a lead screw 8. The movable crossbeam 7 is equipped with a movable hanging seat 9 that can move along its length. The movable hanging seat 9 is also provided with a threaded hole that cooperates with the lead screw 8. One end of the lead screw 8 is connected to the movable motor 12 on the frame 1. The bottom of the movable hanging seat 9 is equipped with a winding shaft 10 and a winding motor 11. The winding shaft 10 and the winding motor 11 are connected to each other. Next, the winding motor 11 is a motor with a self-locking function, such as a worm gear motor; the upper end of the hoisting rope 13 is wound around the winding shaft 10, and the lower end is fixedly connected to the connecting frame 14. A hoisting rope 15 is provided on each side of the lower end of the connecting frame 14, and the end of the hoisting rope 15 is fixedly installed with a hook 16 for hooking the hoisting hole 30; two oppositely distributed placement seats 17 are provided on one side of the frame 1 of the mixing shaft 2, and each placement seat 17 is provided with a slot 20 for locking the placement shaft 22; a collection hopper 18 is installed below the two placement seats 17, and a valve 19 is installed at the discharge port at the bottom of the collection hopper 18.

[0022] Further reference Figure 3 As shown, the cover plate 21 of the mixing tank 3 is provided on the side wall of the mixing tank 3. The cover plate 21 is an arc-shaped plate. Each of the four corners of the cover plate 21 is provided with a mounting countersunk hole 25 for the fixing bolt to pass through. The shoulder of the feed inlet of the mixing tank 3 is provided with a threaded hole corresponding to the position of the mounting countersunk hole 25. After the cover plate 21 is installed on the side wall of the mixing tank 3, the side wall of the mixing tank 3 forms a complete cylinder.

[0023] Furthermore, the transmission mechanism includes a driving gear 5 and two driven gears 6 with the same number of teeth. The driving gear 5 is mounted on the motor shaft of the mixing motor 4, and the two driven gears 6 are respectively mounted on the shaft ends of the two mixing shafts 2. The driving gear 5 meshes with the two driven gears 6 for transmission. Similarly, the transmission mechanism can also adopt belt pulley transmission.

[0024] Furthermore, such as Figure 8 As shown, the two ends of the mixing shaft 2 are also provided with limiting shoulders 33 with a diameter larger than that of the working section. The limiting shoulders 33 and the working section of the mixing shaft 2 are connected by a conical transition. The structural design of the mixing shaft 2 effectively ensures that the mixing tank 3 will not detach from the working section of the mixing shaft 2 during the rotation process.

[0025] Furthermore, the number of ribs 27 of the mixed drug prism 26 is eight, or it can be set to six; the specific number can be designed according to needs.

[0026] Furthermore, such as Figure 6 As shown, the inner wall of the mixing tank 3 is provided with a plurality of arc-shaped protrusions 32. The number of arc-shaped protrusions 32 is odd. The two sides of the arc-shaped protrusions 32 are rounded with the inner wall of the mixing tank 3. The arc-shaped protrusions 32 play a certain lifting role. The odd number of them is set to avoid the arc-shaped protrusions being on the diagonal of the circumference, which would cause the mixing prism 26 to deform too much and get stuck.

[0027] Furthermore, such as Figure 7 As shown, the number of hoisting holes 30 on the limiting block 23 is three, and the specific number can be designed according to actual needs.

[0028] Furthermore, the electrostatic conductive layer 34 on the outside of the mixing prism 26 and the mixing shaft 2 is made of electrostatic conductive rubber. The main purpose of using electrostatic conductive material is to ensure the safety of the mixing process and avoid electrostatic detonation of the explosive.

[0029] Furthermore, the length of the cover plate 21 is greater than two-thirds of the length of the mixing tank 3. By setting the length of the cover plate 21 to be larger, it is convenient to unload the explosives and clean the inner cavity of the tank.

[0030] Furthermore, such as Figure 3 As shown, the cover plate 21 is provided with a handle 24. The outer side of the handle 24 is flush with the outer side of the cover plate 21. By providing the handle 24, it is convenient to open the cover plate 21 without damaging the cylindrical outer surface of the medicine container 3.

[0031] Working principle: During loading, the mixing tank 3 is placed on the placement seat 17 with the loading port facing upwards. Loading is done manually. After loading is complete, the cover plate 21 is closed and locked. The moving motor 12 and the winding motor 11 are started to hoist the mixing tank 3 onto the mixing shaft 2. The hook 16 is released and moved upwards. The mixing motor 4 is started, which drives the mixing shaft 2 and the mixing tank 3 to rotate. The mixing prism 26, under the action of its own structure and the counterweight ball structure, is positioned relative to the mixing tank. 3. The mixing prism 26 moves relative to the explosive to mix the explosive. It can fit against any part of the inner wall of the mixing tank 3, and there are no dead corners in the mixing. After the mixing is completed, the mixing motor 4 stops, the mixing tank is hoisted onto the placement seat 17, the cover is opened, and the mixing tank 3 is rotated so that its loading port faces downward. The explosive falls into the collection hopper 18 for collection. When cleaning, the mixing prism 26 can be directly removed for cleaning. Then, other explosives are replaced with raw materials for loading. The above steps are repeated to complete the mixing.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment as needed without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
