Description

Technical Field

[0001] This invention relates to the field of emulsion explosive production technology, specifically to a static disperser for emulsion explosive production. Background Technology

[0002] In the production of emulsion explosives, static dispersers are typically used to disperse and agitate fluid raw materials to achieve thorough mixing. Static dispersers utilize internal units or components to disperse and agitate fluid raw materials, thereby achieving mixing. However, existing static dispersers have relatively simple or singular internal unit or component structures with a lack of coordination between them, resulting in poor agitation and dispersion effects and uneven and incomplete mixing of the fluid raw materials. Summary of the Invention

[0003] The purpose of this invention is to provide a static disperser for the production of emulsion explosives, which effectively agitates and disperses fluid raw materials, resulting in uniform and thorough mixing of the fluid raw materials.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a static disperser for emulsion explosive production, comprising a dispersion tube, one end of which is provided with an inlet flange and the other end with an outlet flange, and a feed pipe is also provided on the dispersion tube; an annular seat is provided inside the dispersion tube, and a first spiral dispersion component and a second spiral dispersion component are provided on the annular seat, the first spiral dispersion component being located outside the second spiral dispersion component; the first spiral dispersion component is composed of a first spiral strip and a second spiral strip, which are intertwined; the second spiral dispersion component is composed of a first spiral tube body and a second spiral tube body, which are intertwined; a first opening groove is provided on the first spiral tube body, which is spirally arranged along the surface of the first spiral tube body; a second opening groove is provided on the second spiral tube body, which is spirally arranged along the surface of the second spiral tube body.

[0005] Furthermore, the first spiral tube body is composed of several first spiral short tubes spliced ​​together; the second spiral tube body is composed of several second spiral short tubes spliced ​​together.

[0006] Furthermore, each of the first spiral short tubes and the second spiral short tubes is provided with multiple flow guide holes.

[0008] Furthermore, the first spiral strip is composed of several first spiral blades spliced ​​together; the second spiral strip is composed of several second spiral blades spliced ​​together.

[0009] Furthermore, each of the first and second spiral blades has an arc-shaped groove on its inner side.

[0010] Furthermore, each of the first and second spiral blades has an arc-shaped protrusion on its outer side.

[0011] Furthermore, the ring seat includes a fixed ring disposed on the inner annular surface of the dispersion tube, and a fixed post is disposed inside the fixed ring; the first spiral blade and the second spiral blade closest to the inlet flange are disposed on the fixed ring, and the first spiral short pipe and the second spiral short pipe closest to the inlet flange are disposed on the fixed post; a connecting rod is connected between the fixed post and the fixed ring.

[0012] Furthermore, a filter assembly is provided on the ring seat.

[0013] Furthermore, the filter assembly is a filter screen, which is disposed between the fixed post and the fixed ring.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows.

[0015] 1. By setting up a first spiral strip and a second spiral that are intertwined, the mixed fluid material flowing through the dispersion tube is disturbed and dispersed multiple times; and the spiral groove formed between the first spiral strip and the second spiral strip has a cutting and dispersing effect on the mixed fluid material, further improving the disturbance and dispersion effect.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0029] Please see Figures 1-9The present invention provides a technical solution: a static disperser for emulsion explosive production, comprising a dispersion tube 1, an inlet flange 11, and an outlet flange 12, wherein the inlet flange 11 and the outlet flange 12 are respectively installed at both ends of the dispersion tube 1; a feed pipe 13 for injecting fluid raw materials into the dispersion tube 1 is provided on the dispersion tube 1, and the feed pipe 13 is close to the inlet flange 11; the inlet flange 11 and the outlet flange 12 facilitate connection with external equipment, and the inlet flange 11 is used to connect to external feeding equipment and inject fluid raw materials into the end of the dispersion tube 1 where the inlet flange 11 is located; a first spiral dispersion component 3 and a second spiral dispersion component 4 are provided inside the dispersion tube 1 for agitating and dispersing the mixed fluid raw materials; the first spiral dispersion component 3 covers the outside of the second spiral dispersion component 4; a ring seat is also provided inside the dispersion tube 1 for fixing the first spiral dispersion component 3 and the second spiral dispersion component 4.

[0030] The first spiral dispersion component 3 is composed of a first spiral strip 31 and a second spiral strip 32. The first spiral strip 31 and the second spiral strip 32 are arranged to be intertwined. Specifically, the first spiral strip 31 is composed of several first spiral blades spliced ​​together, and the second spiral strip 32 is composed of several second spiral blades 321 spliced ​​together. Adjacent first spiral blades and adjacent second spiral blades 321 can be spliced ​​together by welding, or by using a limiting rod interference fit limiting hole to achieve stable splicing, or other existing splicing methods can be used.

[0031] The first spiral 31 and the second spiral 32 formed by splicing are intertwined, but each first spiral 31 does not contact its adjacent second spiral 32, that is, as shown in the figure. Figure 4 As shown, a spiral groove 33 is formed between the first spiral strip 31 and the second spiral strip 32; at the same time, an arc groove 34 is provided on the inner side of each first spiral strip and the second spiral strip 321, and an arc protrusion 35 is provided on the outer side of each second spiral strip 321. The arc groove 34 and the arc protrusion 35 are used to enhance the disturbance and dispersion effect on the mixed fluid material inside the dispersion tube 1. Since the first spiral strip 31 and the second spiral strip 32 are intertwined, the mixed fluid material flowing through the dispersion tube 1 is disturbed and dispersed multiple times. The spiral groove 33 formed between the first spiral strip 31 and the second spiral strip 32 has a cutting and dispersing effect on the mixed fluid material, further enhancing the disturbance and dispersion effect.

[0032] The second spiral dispersion component 4 is composed of a first spiral tube 41 and a second spiral tube 42, and the first spiral tube 41 and the second spiral tube 42 are also intertwined; a first opening groove 412 is provided on the first spiral tube 41, and the first opening groove 412 is spirally arranged along the surface of the first spiral tube 41; a second opening groove 422 is provided on the second spiral tube 42, and the second opening groove 422 is spirally arranged along the surface of the second spiral tube 42.

[0033] The first spiral tube body 41 is composed of several first spiral short tubes 411 spliced ​​together; the second spiral tube body 42 is composed of several second spiral short tubes 421 spliced ​​together; due to the provision of the first opening groove 412 and the second opening groove 422, the sides of the first spiral short tube 411 and the second spiral short tube 421 are open structures; the first spiral strip 31 and the second spiral strip 32 are located outside the first spiral short tube 411 and the second spiral short tube 421, that is, the first spiral blade and the second spiral blade 321 are located outside the first spiral short tube 411 and the second spiral blade 321 are located outside the second spiral short tube 421; the first spiral short tube 411 and the second spiral short tube 421 have an open spiral tubular structure, that is, the inner and outer sides of the first spiral short tube 411 and the second spiral short tube 421 are both arc surface structures, which can help improve the dispersion effect on the mixed fluid raw materials.

[0034] Since the first spiral short tube 411, the second spiral short tube 421, the first spiral strip 31, and the second spiral strip 32 all disperse and disturb the mixed fluid raw material, and the first spiral strip and the second spiral strip 321 are located outside the first spiral short tube 411 and the second spiral short tube 421, they can perform multi-directional disturbance and dispersion on the mixed fluid raw material between the first spiral dispersion component 3 and the second spiral dispersion component 4. Furthermore, with the combined dispersion action of the first spiral dispersion component 3 and the second spiral dispersion component 4, the mixed fluid raw material between the first spiral dispersion component 3 and the second spiral dispersion component 4 has a mutual squeezing and turbulence effect, which can greatly improve the disturbance and dispersion effect.

[0035] In addition, multiple guide holes 43 are provided through each of the first spiral short tube 411 and the second spiral short tube 421. The guide holes 43 also help to disturb and disperse the mixed fluid material. At the same time, the guide holes 43 are used to connect the fluid material inside and outside the first spiral short tube 411 and the second spiral short tube 421. All the guide holes 43 on the first spiral tube 41 are arranged in a spiral pattern, and all the guide holes 43 on the second spiral tube 42 are also arranged in a spiral pattern. This can reduce the obstruction to the fluid material and also help to improve the dispersion effect of the fluid material.

[0036] At the same time, each of the first spiral short tubes 411 and the second spiral short tubes 421 has multiple turbulence gaps 44, which further enhance the overall turbulence dispersion effect.

[0037] Therefore, the static disperser achieves a good disturbance and dispersion effect on the mixed fluid raw materials through the cooperation of the first spiral strip 31, the second spiral strip 32, the first spiral tube 41 and the second spiral tube 42, and can evenly and fully mix the fluid raw materials.

[0038] The ring seat includes a fixing ring 21, which is coaxially disposed inside the dispersion tube 1 and close to the feed tube 13. A fixing post 22 is coaxially disposed inside the fixing ring 21, and a connecting rod 23 connects the fixing post 22 and the fixing ring 21. The first spiral blade and the second spiral blade 321 closest to the inlet flange 11 are disposed on the fixing ring 21, and the first spiral short tube 411 and the second spiral short tube 421 closest to the inlet flange 11 are disposed on the fixing post 22. The fixing ring 21 and the fixing post 22 are used to install and fix the first spiral dispersion assembly 3 and the second spiral dispersion assembly 4.

[0039] A filter assembly is provided on the ring seat; the filter assembly can be a filter screen 51, which is sleeved on the outside of the fixed column 22 and contacts the inner ring surface of the fixed ring 21. Impurity particles in the mixed fluid raw material are pre-filtered by the filter screen 51, and the filtered mixed fluid raw material is then fully and evenly mixed by the first spiral dispersion assembly 3 and the second spiral dispersion assembly 4.
