[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme for an M-type emulsion explosive jet emulsification device:

The SK-type static mixing unit is multiple and built in the SK-type static mixing tube, and the SK-type static mixing tube is connected to the jet emulsification tube and connected by a flange. The jet emulsification tube is composed of two sections of connection combination, the first jet porous plate, the second ... first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, the first jet porous plate, The jet porous plates are respectively located at the inlet of each section of the jet emulsification tube, and the forward spiral blades and the reverse spiral blades are respectively built-in at the outlet of each section of the jet emulsification tube and welded to the jet emulsification tube; the diaphragm pressure gauge is connected to the jet emulsification tube with a thread, and the pressure gauge is directly installed on the pipeline to display the pressure of this section of the pipeline so as to adjust the pressure drop and balance the emulsification effect of each section of the emulsification tube; the outlet of the jet emulsification tube is connected to the SV type homogenizing mixing tube by a flange; the SV type homogenizing mixing unit is multiple and built-in in the SV type homogenizing mixing tube; the SV type homogenizing mixing tube is connected to the pressure release tube by a flange.

[0007] Furthermore, the diameter of the SK type static mixing tube is Φ32-110 mm, and the length is 500-1000 mm.

[0008] Furthermore, the SK type static mixing unit is welded from left and right twisted single spiral sheets, and its main function is to mix the oil and water phase materials together to provide a uniform mixed liquid for emulsification. The twisting angles are 180° and 270° respectively, and the length of a single SK type static mixing unit is 30 to 100 mm.

[0009] Furthermore, the outer diameter of the first jet porous plate / the second jet porous plate is 40 to 110 mm, the number of holes on the first jet porous plate / the second jet porous plate is 50 to 300, and the diameter of the holes is 1.0 to 10.0 mm; the size and number of the holes on the jet plate are determined according to the flow rate of the mixed liquid and the pressure required for emulsification of the oil-water phase material, and holes of different sizes are designed according to the fluidity of the mixed liquid to balance the pressure drop in each section and ensure the uniformity of emulsification.

[0011] The pressure relief tube is an empty tube with a large cross section. The emulsified matrix has a certain pressure after passing through the homogenizing mixing tube. After entering the pressure relief tube, the flow area suddenly increases, which can reduce the fluid velocity and improve production safety.

[0018] (6) The use of a large-section pressure relief pipe is conducive to releasing excess pressure, allowing the outlet matrix to flow stably at a low speed, thereby improving the inherent safety of the production line.

[0019] (7) The use of diaphragm pressure gauge is conducive to accurately displaying the pipeline pressure, so as to adjust the pressure drop at each level and make the emulsification pressure distribution at each level more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to better describe the present invention, an M-type emulsion explosive jet emulsification device of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

The diaphragm pressure gauge 7 is connected to the jet emulsification tube 4 with a thread, and the working pressure is 0.3-1.2Mp; the outlet of the jet emulsification tube 4 is connected to the SV type emulsification mixing tube 9 by a flange; the SV type emulsification mixing unit 10 is 5-20 and built into the SV type emulsification mixing tube 9. The SV type emulsification mixing unit 10 is rolled into a corrugated sheet from a metal plate, and the corrugated sheet is assembled according to the emulsification requirements. The channels formed by adjacent corrugated units are inclined in opposite directions and staggered at a certain angle, so that the emulsified fluid flows in opposite directions on multiple parallel planes, so that the emulsified fluid impacts each other in the tube, achieving the purpose of strong shear emulsification. The SV type emulsification mixing tube 9 is connected to the pressure release tube 11 by a flange.

[0026] In the embodiment, the number of the jet holes on the first jet porous plate 3 / the second jet porous plate 6 is 50 to 300.

[0027] In the embodiment, the production capacity of the M-type emulsion explosive jet emulsification device of the utility model is 2 to 10m 3 / h, the specific process is:

[0028] S1 mixing: The water-oil phase material delivered from the water-oil phase delivery pump enters the SK type static mixing tube 1. Under the action of the multi-section SK type static mixing unit 2, multi-directional fluids collide with each other to form turbulence, so that the water-oil phase materials are mixed evenly.

[0029] S2 jet emulsification: the water-oil phase mixed material flowing out of the SK type static mixing tube 1 forms a pressure drop at the first jet porous plate 3 to generate a jet. The high-energy jet causes the water-oil phase mixed material to rub, shear and collide to form an emulsion. The emulsion is rotated and mixed under the action of the forward spiral unit 5; the emulsion flow forms a pressure drop at the second jet porous plate 6 to generate a jet again. The emulsion is sheared, collided and emulsified again to form a basically stable emulsified matrix, which is reversely impacted and mixed under the action of the reverse spiral unit 8.

[0030] S3 uniform emulsification: The emulsified liquid enters the SV type uniform emulsification mixing tube 9. Under the action of the SV type uniform emulsification mixing unit 10, the high-speed flowing emulsion flows in opposite directions on multiple parallel planes, so that the emulsified fluids impact each other in the tube, and the strong shearing is carried out for fine and uniform emulsification to form a high-quality emulsified matrix.

[0031] S4 pressure release: Due to the high pipeline delivery pressure, after the emulsification is completed, the emulsified matrix still has a certain spraying ability. In order to improve the safety of the production line, the emulsified matrix enters the pressure release pipe 11, and the excess pressure is released to form a stable colloid outflow.

[0032] S5 pressure detection: The diaphragm pressure gauge 7 is connected to the jet emulsification tube 4 to display the pressure inside the jet emulsification tube 4, providing a basis for adjusting the production capacity of emulsion explosives.
