Description
Technical field
The invention belongs to emulsion explosive prodn technology, relate in particular to a kind of emulsion [explosive pharmacy and powder charge continuous production technology.
Background technology
At present, there are a lot of problems in emulsion [explosive continuous production technology in the prior art.
At first, in the existing emulsion [explosive continuous production technology, generally comprise preparation aqueous phase solution and oil-phase solution, colostrum, smart breast, cooling, sensitization powder charge and packaging and other steps successively.Adopt such process method; Latex is processed the back and is cooled off colloid through continuous enclosed cooler, steel band cooler or immersion continuous cooling equipment earlier; After the colloid temperature is cooled to 40～70 ℃ of scopes from 100 ℃ ± 15 ℃; Add chemical sensitizer or physical sensitization agent again, form the emulsion [explosive of chemical sensitization or physical sensitization.Adopt the technology of this back sensitization powder charge of cooling earlier, during the latex cooling,, all can produce damage in various degree latex because of it directly soaks or receives cooler to stir, scrape.
Secondly, in the existing emulsion [explosive continuous production technology, smart newborn device all uses the emulsor of dynamic shearing formula, and the power of consumption is very big and production capacity is little.And, adopting rotary smart emulsor, the latex temperature generally is higher than water, oil phase temperature after the emulsification; No matter have or not sealing, in oil, water cutout back or the cutout of sealing water coolant, still in the running like emulsor; All be prone to produce heat built-up and explosion caused danger, thereby security is relatively poor.
At last, because of medicine attitude thickness that becomes after cooling, increased the difficulty of follow-up powder charge, sensitization powder charge system generally adopts the paper web charge machine to carry out powder charge, and loading rate is low.
Summary of the invention
The technical problem that the embodiment of the invention will solve does not have intensification after being to provide a kind of emulsification, and is safe, and the latex damage is few, emulsion [explosive pharmacy and powder charge continuous production technology.
The embodiment of the invention is achieved in that a kind of emulsion [explosive pharmacy and powder charge continuous production technology, comprises the steps:
(1) prepares aqueous phase solution and oil-phase solution respectively;
(2) press processing compound, aqueous phase solution and oil-phase solution are conveyed into the mixing of colostrum device respectively, carry out colostrum, send into static mixer then and carry out the essence breast;
(3) be to send into sensitization powder charge system under the 88-92 ℃ of condition to carry out sensitization processing back powder charge with the essence latex in temperature; After the cooling system cooling, deliver to packaging system again and pack, said essence latex is directly sent into sensitization powder charge system without cooling and is carried out sensitization processing back powder charge.
Compared with prior art; The technical scheme that the embodiment of the invention provides; Because smart newborn device does not adopt rotary smart emulsor, and adopt static mixer, thereby avoided because of latex temperature after the emulsification is higher than water, the oil phase temperature produces the explosion caused danger of heat built-up.And the embodiment of the invention adopts the technology of first sensitization powder charge postcooling, the direct immersion when having avoided the latex cooling, or receive cooler stirring, scrape, thereby also avoided the damage in various degree that thus latex is produced.
