At present, the main emulsification modes of the emulsification process in the production of the emulsion explosive in China are three types of medium-high rotation speed mechanical stirring type single-stage emulsification, medium-low rotation speed mechanical stirring combined emulsification and multi-stage pipeline type mixed emulsification. The emulsifier has the defects of high mechanical stirring speed, high energy consumption, small gap between a stator and a rotor, easy heat accumulation, easy explosion accident caused by metal friction during mechanical failure and incapability of meeting the requirement of safe production; the safety of the medium-low rotation speed mechanical stirring combined type emulsification is greatly improved compared with that of the medium-high rotation speed mechanical stirring single-stage emulsification, but the coarse emulsion is still mechanically stirred, the same as the single-stage emulsification process, has certain safety risk and high energy consumption, and meanwhile, the danger point is further increased by conveying the emulsion matrix between the coarse emulsion stirring process and the fine emulsion through a 0-class equipment screw pump, and the problems are brought into important attention of production enterprises and are expected to be further improved.

The sensitizer is added into the output pipeline of the emulsifying device 100 through a sensitizer input pipeline, and forms an emulsion explosive after being sensitized with the emulsified matrix which is emulsified successfully and is discharged from an explosive outlet.

Referring to fig. 1-4, the emulsifying device 100 includes an emulsifying container 30 having an emulsifying chamber, a rough cutting mechanism 40 and a fine cutting mechanism 50 mounted in the emulsifying chamber. The rough cutting mechanism 40 and the fine cutting mechanism 50 are provided with a plurality of shearing holes 60, the fine cutting mechanism 50 is surrounded outside the rough cutting mechanism 40 at intervals, the fine cutting mechanism is made to wrap the rough cutting mechanism 40, the mixed solution enters the rough cutting mechanism 40, the solution in the rough cutting mechanism 40 is sprayed outwards through the shearing holes 60, primary solution shearing and mixing are completed, rough milk is formed, and under the action of spraying pressure, the rough milk sprayed from the rough cutting mechanism 40 passes through the fine cutting mechanism 50 and is sheared and mixed again through the shearing holes 60, so that fine milk is formed. The oil phase and the water phase are firstly mixed through the arranged oil-water phase primary mixing pipe to form an oil-water phase mixed solution, the oil-water phase mixed solution is mixed before entering the emulsifying device 100, the mixed solution enters the rough cutting mechanism 40, under the action of high pressure, the mixed solution enters the rough cutting mechanism 40 and is sprayed out of the shearing holes 60 on the rough cutting mechanism to form rough emulsion, and under the action of high pressure, the rough emulsion passes through the shearing holes 60 of the fine cutting mechanism 50 and is sprayed out to form fine emulsion, the solution is sheared for a plurality of times to form a water-in-oil emulsion matrix, and the oil-water phase mixed solution is cut by the shearing holes 60 to break dispersed phase droplets into superfine droplets, so that the purpose of uniformly mixing the oil-water phase mixed solution is realized, and the emulsifying effect is improved. The whole milk making process does not need a stirring device, and a stirring-free emulsification mode is formed through spraying and shearing, so that the problem of safety accidents caused by stirring in the prior art is avoided, and the problem of poor stirring-free emulsification effect in the prior art is also avoided.

In the prior art, the stirring-free mixing is carried out by a multi-cavity mixer, specifically, the water phase is injected into a plurality of cavities filled with the oil phase at high pressure, in the mixing process, the water phase is injected into the mixing cavity by high pressure injection to realize oil-water phase mixing and emulsification, and the water phase is only mixed and introduced into the cavity filled with the oil phase, so that the disadvantage of the method is that the oil phase and the water phase are not fully mixed, the separation condition of the oil phase and the water phase is obvious, the granularity of the formed emulsion is large, and the emulsifying effect is poor.

Specifically, the rough cutting mechanism 40 includes a nozzle 41 and a nozzle 43 mounted at the end of the nozzle 41. The spray pipe 41 is a straight pipe body, and a plurality of shearing holes 60 are formed at the upper end and the lower end of the spray pipe 41, and the oil-water phase mixed solution enters from the spray pipe 41 and is sprayed out from the shearing holes 60 formed in the spray pipe. Of course, in other embodiments, the spout 41 may be configured in a curvilinear fashion, such as an S-shape or a fold line, etc., as desired.

The fine cutting mechanism 50 includes an upper fine cutting pipe 51, a lower fine cutting pipe 53, and a cutting increasing barrel 55. The upper and lower fine cut pipes 51 and 53 are matched with the shape of the nozzle 41, and are also straight pipes. The upper fine cutting pipe 51 and the lower fine cutting pipe 53 are integrally provided with a plurality of shearing holes 60, and the pipe diameters of the upper fine cutting pipe 51 and the lower fine cutting pipe 53 are larger than the pipe diameter of the spray pipe 41 so as to be sleeved outside the spray pipe 41. In order to ensure that the solution ejected from the nozzle 41 is discharged through the upper and lower fine cutting pipes 51 and 53, both ends of the upper and lower fine cutting pipes 51 and 53 are provided in a sealed state so that the solution can be ejected only from the opened shearing holes. Moreover, the fine cutting pipes are arranged up and down, so that the solution can be sheared and mixed through a plurality of positions, and the working efficiency is improved.

Referring to fig. 2, the emulsifying container 30 includes a cylindrical body 31 having a hollow interior, and an introduction section 33 extending from the top of the body 31 along the axial direction thereof, wherein the introduction section 33 is connected to a pipe connecting the oil-water primary mixing pipe through a flange 36, and the oil-water mixed solution fed from the oil-water primary mixing pipe enters the spray pipe 41 from the end of the introduction section 33.

As shown in fig. 1, the cutting barrel 55 is axially mounted in the barrel 31, the nozzle 41 axially penetrates from the introduction section 33 and extends into the cutting barrel 55, the upper fine cutting pipe 51 is axially and alternately sleeved at one end of the nozzle 41 located in the introduction section 33, the lower fine cutting pipe 53 is axially and alternately sleeved at one end of the nozzle 41 located in the cutting barrel 55, and the shearing holes 60 are respectively formed in the nozzle 41, the upper fine cutting pipe 51, the lower fine cutting pipe 53 and the cutting barrel 55. A liquid spraying cavity 52 is formed between the upper fine cutting pipe 51 and the inner side wall of the leading-in section 33, a liquid spraying cavity 54 is also formed between the increasing and cutting barrel 55 and the barrel 31, and the inner side wall of the leading-in section 33 extends to the top of the increasing and cutting barrel 55. As shown in fig. 3, a through hole 331 with a larger aperture is formed at an end of the inner side wall of the introducing section 33 connected to the cutting barrel 55, the inside of the cylinder 31 is communicated with the introducing section 33 through the through hole 331, and under the action of pressure, the emulsion in the inside of the cylinder 31 and the inside of the introducing section 33 are converged to an output pipeline to form a flow passage. It will be appreciated that the oil-water mixture enters the nozzle 41 under high pressure such that the solution entering the nozzle 41 is ejected under pressure towards the shear holes 60 to form coarse emulsion. A part of the coarse emulsion at the upper end is sheared again by the upper fine cutting pipe 51 under the action of pressure to form fine emulsion, another part of the mixed solution entering the spray pipe 41 from the introducing section 33 flows into the lower end of the spray pipe 41, a part of the mixed solution is sheared again by the lower fine cutting pipe 53 and then sprayed into the increasing and cutting barrel 55, and another part of the mixed solution is sprayed into the increasing and cutting barrel 55 by the spray nozzle 43, and all the emulsion in the increasing and cutting barrel 55 is sprayed onto the inner wall of the barrel 31 through the shearing holes 60 on the increasing and cutting barrel 55 under the action of pressure, so that layer percolation is generated along the inner wall. In this way, the emulsion sprayed after being sheared by the spray pipe 41 is sheared and uniformly mixed by the upper fine cutting pipe 51, the lower fine cutting pipe 53 and the cutting increasing barrel 55, and is crushed to form emulsion drops with small particles, so that the emulsion is fully and uniformly mixed, and the water-in-oil emulsion matrix particles are formed.

Wherein, the apertures of the shearing holes 60 on the upper and lower fine cutting pipes 51 and 53 are smaller than the shearing holes 60 on the spray pipe 41, so that the shearing of the spray pipe 41 forms coarse emulsion, and the emulsion particles sprayed from the upper and lower fine cutting pipes 51 and 53 are smaller to form fine emulsion, thereby achieving the purpose of uniform mixing. Specifically, in this embodiment, the shearing hole 60 is a circular hole, and in other embodiments, the shearing hole 60 may be a square hole, a diamond hole, or the like.

As shown in fig. 1, the emulsifying device 100 further comprises a fine cutting tube 70, the emulsifying container 30 further comprises an output section 35 connected to the introducing section 33, the fine cutting tube 70 is axially installed in the output section 35 and one end is connected to an upper fine cutting tube 51 of the fine cutting mechanism 50. The solution entering the output section 35 enters the fine cut pipe 70 to be sheared and discharged from the fine cut pipe 70, and the fine cut pipe 70 is sheared again to improve the mixing effect.

Further, the aperture of the shearing holes 60 of the last fine cutting pipe 70 is smaller than the apertures of the shearing holes 60 of the upper fine cutting pipe 51, the lower fine cutting pipe 53 and the cutting drum 55. The last fine cutting pipe 70 is used as a last fine cutting structure, and the solution finally collected into the output section 35 can be completely discharged from the shearing holes 60 of the last fine cutting pipe 70, so that a step of further fine cutting particles is added to the solution, even if the solution with larger particles exists in the previous step, all the cut and dispersed particles with uniform size can be obtained in the last fine cutting step of the last fine cutting pipe 70, and thus the uniform mixing effect is better.

The spray head 43 is positioned in the cutting barrel 55, the spray head 43 is spherical, and a plurality of spray nozzles 45 are annularly arranged on the spherical surface of the spray head 43. The spray nozzle 43 is connected to the spray pipe 41, and the emulsion is sprayed into the cutting-increasing barrel 55 through the spray nozzle 45, at this time, the emulsion in the cutting-increasing barrel 55 is driven by the spraying force of the spray nozzle 45 to turn the liquid in the barrel up and down, so that the spraying force forms stirring force, and the stirring force is fully collided and mixed with the liquid sprayed from the middle part of the spray pipe 41 to form water-in-oil emulsion matrix particles. Therefore, the spraying force of the nozzle 45 provides stirring force for the solution in the barrel, so that the stirring force is formed, the solution is more uniformly mixed, and the uniform mixing effect is better. No other stirring device is needed, and explosion caused by friction generated by the stirring device is avoided, so that the safety coefficient is greatly improved.

It will be appreciated that, in order to make the solution sprayed from the spray head 43 pass through the shearing holes 60 of the cutting-increasing barrel 55 to be finely cut after being turned up and down, the shearing holes 60 on the cutting-increasing barrel 55 are surrounded by the area close to the spray head 43, and the solution is discharged from the shearing holes 60 on the cutting-increasing barrel 55 during the turning process, so as to further improve the fine cutting efficiency of the cutting-increasing barrel 55.

As shown in fig. 1 and 4, the inner and outer walls of the emulsifying container 30 are spaced apart from each other to form a space, and the space is filled with a heat-insulating liquid or a heat-insulating vapor. Specifically, the heat-preserving liquid may be heat-preserving water, and the heat-preserving water or heat-preserving steam enters the emulsification container 30 to continuously provide temperature for the emulsion therein, so as to ensure the temperature condition required in the process of uniformly mixing the emulsion.

Referring to fig. 5, the invention further provides a system for emulsifying and mixing without mechanical stirring.
