Embodiment 1
[0082] like figure 1 and figure 2 As shown, the continuous automatic production line of priming explosives pyrotechnic agents provided by Embodiment 1 of the present invention is mainly composed of a batching room 10, a compounding room 20, a suction filtration and portioning room 30, a plurality of drying rooms 40 and a boxing room 180, wherein , the batching room 10 is an ordinary workshop, the compound room 20, the suction and filtration room 30, the multiple drying rooms 40 and the boxing room 180 are all anti-knock workshops, and they are arranged in the workshop in sequence according to the process, and two adjacent The anti-blast workshops of each process are connected and separated by steel anti-blast windows and movable doors. In this embodiment, each drying room 40 is provided with an internal spiral rotary dryer, and multiple internal spiral rotary dryers in each drying room 40 are sequentially connected in series to form a drying system.
[0083] The batching ro...
Embodiment 2
[0113] like Figure 9 and Figure 10 As shown, the continuous automatic production line for priming explosives provided by Embodiment 2 of the present invention differs from Embodiment 1 in that: three internal spiral rotary dryers 401 and one internal spiral rotary cooling Between the machines 501, the transmission of the priming powder crystals is automatically realized successively through the transfer hopper 190.
[0114] Other configurations and connections are the same as those described in Embodiment 1, so only parts of them are shown in the figure, and the same functional configurations are marked with the same symbols.
Embodiment 3
[0116] like Figure 11 As shown, in the continuous automatic production line of priming explosives provided by Embodiment 3 of the present invention, the difference between this embodiment and Embodiment 1 is that a drying room 40 is provided, in which two internal spiral rotary drying Machine 401, and used in series, as shown in the figure, the crystallization of priming powder is input to the input end of the left inner spiral rotary dryer 401, and enters the right inner spiral dryer 401 from the output end of the left inner spiral rotary dryer The input end of the spiral rotary dryer 401, after drying, enters the cold medicine room 50 from the right passage; similarly, two internal spiral rotary coolers 501 are arranged in the cold medicine room 50, and are used in series. Wherein the detonating explosive crystallization that finishes drying is input to the input end of left side internal spiral type rotary cooler 501, and enters right side internal spiral type rotary coole...

Abstract
The invention relates to the technical field of primary explosive production in civil explosion devices and ammunition detonators, and provides a continuous automatic production technology and a production line of a primary explosive pyrotechnic medicine based on an internal screw type rotary heat exchanger. The technology comprises the following steps: carrying out curing and cooling crystallization on a primary explosive reaction solution by using two independent reactors; carrying out vacuum pumping drainage filtration to separate primary explosive crystals from a reaction mother solution; washing by purified water, and immersing and washing by industrial anhydrous ethanol; dividing wet products after the pumping drainage into a plurality of parts; dynamically, continuously and automatically drying and cooling all parts of the primary explosive by adopting the internal screw type rotary heat exchanger; and sieving, collecting, and boxing. The defects of long process time and high energy consumption caused by repeated heating and cooling due to the use of a chemical combination device can be eliminated, the production efficiency is improved, and energy is saved; and the adoption of the internal screw type rotary heat exchanger realizes the safe, efficient, continuous, automatic and man-machine isolated production process of the primary explosive pyrotechnic medicine.
Description
technical field [0001] The present invention relates to the technical field of production of flammable and explosive materials, the technical field of primary explosive production in the fields of civilian blasting equipment and ammunition detonators, and in particular relates to a continuous automatic production process of primary explosive pyrotechnic agents based on internal spiral rotary equipment and production lines. Background technique [0002] The primary explosive is the initial starting energy of all civilian blasting equipment and ammunition detonators. The main varieties are dinitrodiazonium phenol (DDNP), zinc perchlorate tricarbohydrazide (GTX), perchlorate tricarbohydrazide zinc Cadmium (GTG), nickel hydrazine nitrate (NHN), dextrin lead azide (LA), lead styphenate (LS), basic lead picrate and lead azide double salt (K·D), azide Co-precipitation of lead nitride and lead stefanate (D·S), etc. Because the primary explosive has the characteristics of high sens...
