Abstract
The invention discloses a continuous manufacturing production process for a powdery seismic charge. The production process comprises the following steps of: A, performing screw premixing: conveying ammonium nitrate to a screw premixing part through a screw; meanwhile, conveying wood flour to the screw premixing part through the screw; conveying a composite oil phase to the screw premixing part through an oil sprayer; conveying TNT (Trinitrotoluene) to the screw premixing part through the screw; and premixing on the screw premixing part through the screw; and B, rolling and mixing: rolling and premixing materials and then conveying to a rolling and mixing machine for rolling and mixing; rolling and mixing; and then directly conveying to a charging workshop through screw water cooling. The process has the advantages that: a ball milling mixer and a wheel mill are substituted by the rolling and mixing machine after screw premixing; the time, labor and material resources are saved; and the working efficiency is increased.
Description
Technical field
The present invention relates to powdery explosive-source explosive post production technique field.
Background technology
At present, in powdery explosive-source explosive post serialization pharmaceutical manufacturing line production technique, its production craft step is:

B, material are delivered in the ball mill behind premix and mix, mixing temperature≤84 ℃, after the ball mill mixing through cooling spiral cooling back discharging, drop temperature≤80 ℃;
C, work in-process are carried out quantitative package;
D, work in-process are transported to the rolling worker-house through vehicle, by manual work work in-process and load weighted TNT are added in the wheel roller by proportioning and roll mixing, and rolling mixing temperature is 60-75 ℃;
After mixing, E, wheel roller pack once more;
F, work in-process are transported to the powder charge worker-house through vehicle.See accompanying drawing 1.
There is following weak point in existing explosive-source explosive post discontinuous pharmaceutical manufacturing technology: 1, temperature of charge is high, motor speed is fast, has potential safety hazard; 2, work in-process need the double-handling of twice packing, complex process, production cost be high,
Inefficiency.
Summary of the invention
The object of the invention is exactly to the existing above-mentioned deficiency of explosive-source explosive post pharmaceutical manufacturing technology, and a kind of explosive-source explosive post serialization pharmaceutical manufacturing technology is provided.
Production craft step of the present invention is:
A, spiral pre-mixing: earlier an ammonium nitrate is carried out coarse crushing; Add properties-correcting agent after the coarse crushing; An ammonium nitrate and properties-correcting agent are once pulverized through helical feed to 1 cam kibbler, after an ammonium nitrate after the pulverizing passes through pipeline drying and one-level cyclonic separation, carry out secondary through helical feed to 2 cam kibbler and pulverize; An ammonium nitrate through after the secondary pulverizing is separated in the premix spiral through pipeline drying and two stage cyclone; Wood powder and TNT are delivered in the premix spiral after claiming quantitatively through check weighing, and compound oil phase is delivered in the premix spiral through volume pump after melting, and an ammonium nitrate, compounded oil, TNT and wood powder carry out pre-mixing in the premix spiral;
B, roll mixing: material is delivered to double-deck grinding and mixing machine and rolls mixing behind premix, after the cooling spiral cooling, directly is delivered to the powder charge worker-house through overhead chain conveyer.
In the spiral pre-mixing process step; No. 1 the interior an ammonium nitrate temperature of cam kibbler is 60 ℃, and the EAT of No. 1 cam kibbler is 100 ℃, and the motor speed of No. 1 cam kibbler is 1200 commentaries on classics/min; No. 2 the interior an ammonium nitrate temperature of cam kibbler is 80 ℃; The EAT of No. 2 cam kibblers is 100 ℃, and the motor speed of No. 2 cam kibblers is 1200 commentaries on classics/min, and compound oil phase temperature of fusion is 100 ℃.
Advantage of the present invention is: 1, reduced temperature of charge and motor speed, eliminated potential safety hazard; 2, wood powder and TNT adopt check weighing to claim that quantitatively precision is higher, and quality product is more stable.3, replace original ball mill and wheel roller by double-deck grinding and mixing machine, material is delivered to the powder charge worker-house continuously, has simplified production technique, has reduced production cost, has improved working efficiency;
