Problems solved by technology

The Chinese invention patent with the application number CN201710078976.4 realizes the mixing of porous granular ammonium oil explosives and latex matrix, but due to the structural limitations of the vertical mixing mixer, dead angles and segregation are likely to occur during the mixing of materials during the working process Severe, at the same time, the caking inside the conical shell is serious
Destroy the porous granular structure of ammonium nitrate, and the uniformity of mixing is insufficient

Embodiment 1

[0066] like Figure 1-3 As shown, a kind of emulsified ammonium oil explosive pair-roll mixing device of the present invention comprises a mixing tank, two spiral conveying rollers installed in parallel in the longitudinal direction in the mixing tank, and the spiral conveying rollers include a roller shaft and a Bracket vertically fixed on the roller shaft, the mixing tank is provided with a material inlet and a material outlet, and any one of the two spiral conveying rollers is equipped with a mixing driver and drives the other. The transmission part of the roller shaft. The roller shaft is provided with a plurality of brackets. The plurality of brackets on the roller shaft form several groups of brackets. Each bracket of each group of brackets is arranged along the axis of the roller shaft Arranged in a straight line at intervals, each group of brackets is arranged in a circular array along the centerline of the roller shaft; each bracket of any group of brackets on the sam...

Embodiment 2

[0071] A pair of roller mixing device for emulsified ammonium oil explosives of the present invention comprises a mixing tank, two screw conveying rollers arranged in the length direction of the mixing tank, the mixing tank is provided with a feed inlet and a discharge port, Any one of the plurality of rollers is equipped with a mixing driver and a transmission member for driving other rollers to mix materials, and a plurality of brackets are arranged on the rollers.

[0072] In this embodiment, the mixing driver is connected with a governor, and the governor may be a mechanical gearbox mechanically connected to the mixing driver, or a frequency converter electrically connected to the mixing driver. Changing the rotation speed of the roller shaft can change the rate of mixing and conveying and discharging.

[0073] The distance between the blade of the transverse spiral conveying roller and the inner wall of the mixing tank is 6mm.

[0074] like figure 1 , figure 2 As show...

Embodiment 3

[0077] The differences between this embodiment and embodiment 2 are:

[0078] The distance between the blades of the transverse spiral conveying roller and the inner wall of the mixing tank is 3.5 mm. Also in the mixing process, the porous granular structure of ammonium nitrate will not be destroyed, which ensures the product quality of the emulsified ammonium oil explosive. image 3 In the process, the bottom of the mixing tank and the two sides are excessively connected by chamfers (or called mixing tank chamfers), and the size of the mixing tank chamfers ensures that the blades of the transverse spiral conveyor roller and the inner wall of the mixing tank The distance is 3.5mm.

[0079] A board is provided on one side of the outlet. The outlet can be opened or closed through the plugboard. When the mixing drive is turned on for mixing, the outlet should be sealed by the plugboard first, and the mixing tank filled with materials will run for 3 minutes to 10 minutes before o...

Abstract

The invention provides an emulsified ammonium oil explosive double-roll mixing device and a design method, comprising the following steps: S1, preliminary type selection and parameter calculation of the spiral conveying roller of the double-roll mixing device; S2, the screw conveyor of the double-roll mixing device Adjustment and optimization of the parameters of the conveying roller; S3, the design of the spiral conveying roller of the double-roller mixing device; S4, the design of the distance between the spiral conveying roller of the double-roller mixing device and the inner wall of the mixing tank. The design method of the double-roller mixing device for emulsified ammonium oil explosives has the following advantages: it is suitable for production lines of various capacities, and the double-roller mixing device designed according to this scientific and reasonable design method is efficient, simple in structure, and uniform in mixing Well, the raw materials of the emulsified ammonium oil explosives are automatically and efficiently mixed evenly to meet the production requirements to obtain high-quality emulsified ammonium oil explosives.

Description

technical field [0001] The invention relates to the field of explosive production, in particular to a pair-roll mixing device and a design method for emulsified ammonium explosives. Background technique [0002] Emulsified ammonium explosive (also known as heavy ammonium explosive) is a new type of mixed explosive which is composed of latex matrix and porous granular ammonium explosive. That is, the porous granular ammonium nitrate and light diesel oil are mixed in proportion to form the porous granular ammonium fuel oil; the porous granular ammonium fuel oil and the latex matrix are combined with different ratios to form the emulsified ammonium fuel oil with different properties. [0003] In the production process, how to realize the uniform mixing of porous granular ammonium explosives and latex matrix quickly and efficiently, without destroying the porous granular structure of ammonium nitrate, is the basic requirement to meet the production of emulsified ammonium explosi...
