Description

Technical Field

[0001] The invention relates to the technical field of emulsion explosive production, in particular to a stirring device for emulsion explosive production. Background Art

[0002] In the field of industrial explosives, emulsion explosives have become one of the most widely used types of industrial explosives today due to their many advantages such as good explosive performance, safety and relative environmental protection.

[0003] With the vigorous development of industries such as mining and infrastructure construction, the demand for emulsion explosives continues to rise, which puts higher requirements on the production efficiency and quality of emulsion explosives. As a key link in the production process of emulsion explosives, stirring directly affects the final performance of the product. Traditional stirring devices gradually expose a series of problems in the production of emulsion explosives.

[0004] On the one hand, the raw material composition of emulsion explosives is relatively complex, usually including oxidants, combustibles, emulsifiers, sensitizers and other additives. The physical and chemical properties of each component vary greatly, and traditional stirring methods are difficult to ensure that these components are mixed evenly and efficiently. For example, the dissolution rate of oxidant ammonium nitrate particles and the emulsification and dispersion speed of oil phase components are difficult to achieve synchronous coordination through simple stirring, which can easily lead to uneven mixing, thereby affecting the detonation performance of emulsion explosives, and causing problems such as unstable detonation velocity and insufficient power.

[0005] Defects in existing technologies: When stirring, there is no stirring density test after the emulsifier and sensitizer are added and stirred, so the efficiency of their mutual fusion cannot be tested, which will lead to different quality of finished products; During the stirring process, incremental conveying can only be carried out through slow stirring. It cannot be rotated back during the stirring process. After the fixed stirring speed reaches the discharge area, it will be discharged directly. It cannot be reversed to improve the batch with poor mixing efficiency, which reduces the fusion efficiency of the emulsifier and sensitizer finished products, and a large number of defective products will appear, causing industrial pollution and economic losses.

After the fixed stirring speed reaches the discharge area, it will be discharged directly and cannot be reversed to improve the batch with poor mixing efficiency, which reduces the fusion efficiency of the emulsifier and sensitizer finished products and will result in a large number of defective products.

The side is provided with a slide groove that slides with them.

[0031] The mounting frame 22401 can mount and fix the first cylinder 22402 and the second cylinder 22403. At the same time, when the first cylinder 22402 is started, the output end is used to drive the lifting drive plate 2244 to move downward, and the first slide plate 22441 and the first limit slide bar 22442 can be stably fitted with the limit on one side of the forward and reverse drive frame 204, so that the lifting drive plate 2244 is more stable and will not tilt when driven. When the second cylinder 22403 is started, the output end can be used to drive the lifting drive plate 2 254 to move downward, so that the second slide plate 22541 and the second limit slide bar 22542 can be fitted with the forward and reverse drive frame 204 to prevent the lifting drive plate 2 254 from tilting and getting stuck when driven, thereby ensuring the stability of the lifting drive plate 2 2254 when driving the lifting limit sleeve 2246 to move.

[0032] The stirring density detection mechanism is arranged on the top of the cover plate 21 and is used to detect the material mixing density inside the double-axis stirring box 2; the stirring density detection mechanism includes a connecting frame 2041, a bevel gear 1 2042, a bevel gear 2043, a reciprocating screw rod 2044, a reciprocating screw rod pair 2045 and an up and down reciprocating detection component, the connecting frame 2041 is fixedly installed on the top of the connecting rod 2040 near the side of the inclined spiral feeder 1, and the output end of the drive motor 202 passes through the gear housing 203 and the connecting frame 2041 and extends It extends to the bottom of the connecting frame 2041 and is fixedly installed with the bevel tooth 1 2042. The end of the reciprocating screw 2044 away from the bevel screw feeder 1 passes through the interior of the connecting frame 2041 and is fixedly installed with the bevel tooth 2043. The bevel tooth 2043 is meshed with the bevel tooth 1 2042. The reciprocating screw pair 2045 is threadedly connected to the surface of the reciprocating screw 2044. The up and down reciprocating detection assembly is arranged on the surface of the reciprocating screw pair 2045 and is used to drive the detection structure to perform up and down reciprocating detection during the lateral movement.

[0033] The connecting frame 2041 can limit the axial rotation of the helical gear 1 2042 and the reciprocating screw 2044. At the same time, after the driving motor 202 is started, the output end can drive the helical gear 1 2042 to rotate, and then drive the helical gear 2043 meshing with it to rotate, so that the helical gear 2043 drives the reciprocating screw 2044 fixed thereto to rotate. When the reciprocating screw 2044 rotates, it drives the reciprocating screw pair 2045 threadedly connected thereto to reciprocate. At this time, the reciprocating screw pair 2045 can stably reciprocate laterally after being limited by the wave frame 211. The up and down reciprocating detection assembly includes a wave frame 2046, a slide bar 2047, a radioactive density detector 2048, a spring 2049 and a wave frame 211. The wave frame 2046 is slidably matched with the longitudinal limit positions on both sides of the reciprocating screw rod pair 2045. The slide bar 2047 is fixedly installed on both sides of the top of the wave frame 2046 and slidably matched with the top raised portion of the wave frame 211. The inner wall of the wave frame 211 is slidably matched with the surface of the wave frame 2046. The bottom of the spring 2049 is fixedly installed at the bottom center of the wave frame 2046. The top of the spring 2049 is fixedly installed at the bottom of the reciprocating screw rod pair 2045. The radioactive density detector 2048 is fixedly installed with the wave frame 2046. A sliding groove is provided at the top of the cover plate 21, and the radioactive density detector 2048 is slidably matched with the sliding groove.

[0034] During the reciprocating movement of the reciprocating screw rod pair 2045, the reciprocating screw rod pair 2045 can be limited and stably reciprocated by sliding the wave frame 2046 and the inner wall of the wave frame 211. At the same time, the longitudinal limited sliding of the wave frame 2046 can synchronously drive the wave frame 2046 to move horizontally, and during the movement, the slide bar 2047 at the top of the wave frame 2046 slides with the wave frame 211 to make the slide bar 2047 be lifted by the raised part of the wave frame 211, so that the slide bar 2047 drives the wave frame 2046 to move upward during the horizontal movement, and the wave frame 2046 drives the radioactive density detector 2048 to perform an up and down reciprocating movement detection operation. When the wave frame 2046 is bounced up, the spring 2049 is compressed. When the wave frame 2046 moves horizontally over the raised part of the wave frame 211, the spring 2049 is released to make the wave frame 20 46 Stable downward reset is convenient to drive the radioactive density detector 2048 to perform density detection again, ensuring continuous up and down reciprocating detection, measuring the density change of the emulsion explosive raw material during the stirring process to reflect the mixing efficiency. For the radioactive density detector, it is calibrated by measuring the relationship between the intensity change of the ray after passing through the standard sample and the density of the standard sample. The ray passes through the material being stirred. According to the different density of the material, the degree of ray intensity attenuation is different. After receiving the ray, the detector converts the change of ray intensity into a signal related to density, so as to realize detection, and the concentration value of the emulsion explosive can be obtained in real time. If the stirring and mixing is uneven, the density of different areas will be different, and the mixing problem can be discovered in time. Then the interface switches the stirring direction of the stirring rod 22 through the forward and reverse stirring drive switching mechanism, so that the raw materials that do not meet the standards will not continue to the next step and the stirring is reversed.

[0035] A plurality of groups of symmetrically mounted stirring blades 23 are fixedly mounted on the surface of the stirring rod 22 . A plurality of groups of holes are formed inside the stirring blades 23 . Each group of symmetrical stirring blades 23 is inclined at 15 degrees.

[0036] The holes arranged on the symmetrical stirring blades 23 enhance the fusion degree of the mixed raw materials. At the same time, the inclined setting can enable the raw materials to be stably pushed in one direction and then transported to the inside of the first screw conveyor 3. The effect of returning the materials can also be achieved during rotation to avoid continuously falling into the inside of the first screw conveyor 3, thereby improving the yield rate.

[0037] Working principle: In the initial stage of the emulsion explosive production process, the inclined screw feeder 1 accurately transports the raw materials, emulsifier and sensitizer to the inside of the double-shaft mixing box 2 to start the entire mixing process.

[0038] The driving motor 202 is then started, and its output shaft drives the first gear 2021 to rotate. By virtue of the meshing transmission between the gears, the first gear 2021 drives the second gear 2022 to rotate synchronously. The power generated by this rotation process has two key branches: first, the second gear 2022 transmits power to the helical gear 3 226 through the limit drive sleeve 2252 fixedly connected thereto, and the helical gear 3 226 is tightly meshed with the helical gear 5 228, causing the helical gear 4 227 to reverse; second, the second gear 2022 drives the lifting shaft 2251 to rotate through the limit drive sleeve 2252, and the lifting shaft 2251 then drives the lifting gear 225 to rotate.

[0039] At this time, according to the stirring demand, if forward stirring is required, the second cylinder 22403 installed on the mounting frame 22401 responds quickly and starts, and its output end steadily pushes the second lifting drive plate 2254 to move vertically downward. Thanks to the precise fitting and limiting design of the second slide plate 22541, the second limiting slide bar 22542 and the forward and reverse driving frame 204, the second lifting drive plate 2254 can move downward smoothly, thereby driving the second lifting limiting sleeve 2256 to move accurately, so that the lifting shaft 2251 moves downward, and finally the lifting gear 225 is smoothly and tightly engaged with the meshing internal gear sleeve 2255. In this meshing state, the lifting gear 225 drives the driving block 223 to rotate forward, and the driving block 223 drives the worm 222 to rotate, and the worm 222 and the worm wheel 221 work together to drive the stirring rod 22 to rotate rapidly forward. The stirring blade 23 on the stirring rod 22 is inclined at 15 degrees and has holes evenly distributed thereon, which acts like an efficient stirring blade to fully stir the material. The holes not only enhance the fusion degree of the mixed raw materials, but also push the material to move steadily and orderly toward the first screw conveyor 3 .

[0040] When the mixing density detection mechanism finds that the materials are unevenly mixed during the mixing process and reverse mixing is required to improve the mixing effect, the first cylinder 22402 is immediately started, and its output end pushes the lifting drive plate 2244 to move vertically downward. Similarly, relying on the fit and limit protection of the first slide plate 22441, the first limit slide bar 22442 and the forward and reverse drive frame 204, the lifting drive plate 2244 steadily drives the lifting limit sleeve 2246 to move, prompting the rotating limit sleeve 2242 to slide downward until the gear sleeve 2241 and the gear ring 224 are perfectly meshed. At this time, the gear sleeve 2241 drives the gear ring 224 to rotate, driving the drive block 223 to reverse, thereby realizing the reversal of the stirring rod 22, so that the material can be reversed and stirred, effectively preventing unqualified materials from continuously flowing to the first screw conveyor 3, and providing a strong guarantee for improving product quality.

[0041] At the same time, the rotation of the driving motor 202 also shoulders another important mission, that is, driving the stirring density detection work. Its output end drives the bevel gear 1 2042 to rotate synchronously, and the meshing transmission of the bevel gear 1 2042 and the bevel gear 2 2043 causes the reciprocating screw 2044 to rotate, and the reciprocating screw 2044 drives the reciprocating screw pair 2045 threadedly connected thereto to reciprocate. The reciprocating screw pair 2045 achieves stable lateral movement under the limit of the wave frame 211. In this moving process, the wave frame 2046 and the wave frame 211 cooperate exquisitely. As the slide bar 2047 is successively lifted by the raised part of the wave frame 211, the wave frame 2046 drives the radioactive density detector 2048 to perform the up and down reciprocating movement detection operation. The spring 2049 has a reset effect. When the wave frame 2046 is lifted up, the elastic force is compressed. When the wave frame 2046 moves horizontally over the protrusion of the wave frame 211, the elastic force of the spring 2049 is released in time to help the wave frame 2046 to move down stably and reset, ensuring that the radioactive density detector 2048 can continuously and accurately detect the density of different positions of the material. Once uneven mixing is detected and the density of different areas is different, the control system responds immediately and quickly switches the stirring direction of the stirring rod 22 through the forward and reverse stirring drive switching mechanism, so that the raw materials that do not meet the standards are promptly returned for stirring, ensuring the uniformity and efficiency of material mixing.

[0042] When the materials are fully and efficiently stirred in the double-shaft mixing box 2 and reach an ideal mixing state, the uniformly stirred emulsion explosive is orderly transported to the first screw conveyor 3 through the discharge pipe at the bottom of the double-shaft mixing box 2. At the same time, the second screw conveyor 41 accurately transports the modifier to the top center of the first screw conveyor 3. Inside the first screw conveyor 3, the emulsion explosive and the modifier are fully added and fused, and finally the refined production process of the entire emulsion explosive is completed, which effectively solves the problems of the prior art in that the emulsifier and sensitizer are lacking in stirring density detection after feeding and stirring, and the mixing efficiency cannot be improved by flexible rotation during the stirring process, which greatly improves product quality and reduces the output of defective products.
