Improved control of the manufacture of explosive compositions is achieved. The data processor means can provide signals to control the manufacturing process. This invention also provieds a method using modullar controller for an explosives manufacturing.
Description
The controller and the process that the present invention relates to be applied to the manufacturing of explosive composition and described explosive composition is transported to the appointed place.
Civilian mining, quarrying and cutting industry usually in block or packing explosive blasting mode as digging up mine, building the main method of using when riving rock and ore in tunnel, excavation and other activity.
For many years, people have known that a class contains the cheap of a kind of graininess oxidizer salt and fuel composition and explosive reliably, and wherein the maximum of usefulness are ANFO, the mixture of a kind of ammonium nitrate (AN) and the fuel oil of about 6% weight ratio.Thereby because can absorbing moisture content, the AN particulate is difficult to ignite and influence bursting property, so ANFO usually uses under drying condition and seldom is used under the wet condition.
Emulsion explosive is owing to have the water resistance that is better than ANFO explosive, thus suit under the occasion of wet condition, to adopt, but its cost also will obviously increase.Bluhm is at United States Patent (USP) 3,447, disclosed profit emulsion explosive composition first in 978, and it comprises that (a) contains the discontinuous water of inorganic deoxidation saline solution discrete droplets; (b) emulsifying agent that scatters the immiscible organic facies of continuous water of drop and (c) in continuous organic facies, form the drop latex of oxidizer salt solution.Those latexes that contain low amounts of water or adhere to moisture content in discontinuous phase should be called oil molten (melt-in-fuel) emulsion explosive or rather.
Latex self generally can't be ignited, and they must mix the formation explosive with the discontinuous phase such as pro-knock compound from bursting charge (for example trinitrotoluene, nitroglycerine) or hollow agent (void agent).Suitable hollow agent comprises the polystyrene ball of glass microsphere, plastic microsphere, expansion and the bubble of air entrainment.
Water resistance for the low cost of utilizing ANFO and latex are better usually mixes to provide a kind of the explosive that is referred to as " heavy ANFO ' s " usually with ANFO and latex.For example in Australian patent application No.29408/71 (Butterworth) and United States Patent (USP) 3,161,551 people such as () Egly and 4,357,184 people such as () Binet, the composition that is mixed with latex and AN or ANFO has been described.
Explosive is being used under the application of mining industry,, then ignition charge is inserted wherein and followed to bulk or packing explosive and come crushed rock by on rock, drilling through earlier blast hole.The cost of block explosive unit mass generally is lower than the packing explosive, and therefore block explosive is used manyly, especially needs the large-scale mining point of hundreds of tons of explosives in onepull.It is must manually pack it into blast hole and block explosive can load with mechanical device that the packing explosive also has a shortcoming.Block explosive both can have been used particular design after manufacturing works produce transported on trucks also can on-the-spot mixing in the production unit on the truck (being called mobile production unit or MMU ' s) to the mining area.Haulage truck and MMU ' s have pack into mechanical device in the blast hole of block explosive; Adopt different packing methods such as advancing reinforced, perfusion, suction or air blast according to the type of product.Usually utilize machinery or air driven pump that the explosive composition is pushed blast hole by the transmission flexible pipe and finish the suction filling.The air blast filling of explosive composition generally involves and utilizes Compressed Gas that explosive is blown into blast hole by transmitting flexible pipe, and this method is generally used for the transmission of ANFO.
The production plant of MMU ' s and fixed-site has all stored considerable chemicals so that they mix formation explosive composition the most at last.For example, MMU ' s comprises the large-scale reservoir vessel of several storage fuel oils, latex, graininess oxidizer salt, water and other explosive composition.These compositions can mix to produce ANFO or various latex and the batching that weighs AN-FO in different ratios.
The cost of the production plant of MMU ' s and fixed-site and maintenance cost are higher and be suitable for large-scale production.In order to provide hundreds of tons explosive with the productivity ratio of 70-200 kg/minute in a production process, the scale design of factory must be bigger.These production plants are designed to be able to satisfy the needs in big demand market such as large-scale mining area.
Only need the less market of demand of several tons of explosives for each explosion such as Small-scaled Rock Quarry, often by small lot, portable production unit (for example known ASIAMAS-TER board production unit, ASIAMASTER are the trade marks of ICI Australia Operation Pro-prietary Limited.) supply.This class unit is less, is enough to be placed in transport on truck or the train or can be pulled.
The bursting property that obtains to expect and optimize just need mix various compositions in strict accordance with specific ratio.Explosive production merchant must produce batching reliably according to client's specification and quality requirement.In order to raise the efficiency and save cost, the manufacturer must control and can the required explosive charge of inserting of each blast hole of accurate measurement in needs accurately to the volume of production explosive.
All explosive production unit all have the person of being operated to be used for monitoring and regulate the device such as control appliance, meter of the flow velocity of composition and composition mixing rate.Meter, valve etc. are equipped with in small portable production unit inside, control production process by the operator who stand on the element sides.And on MMU ' s, then utilize the system that is connected as a single entity with truck to control these functions by the driver in the compartment/operator.
These systems carry out work by the parameter of monitoring production process, for example can be advanced the speed of feeder and be monitored its aspiration rate by pump speed by the tachometer monitoring.The operator need know that these parameters and actual fed go into the relation between the composition quantity of production process.Therefore, before starting production process, the operator will determine that earlier the raw material quantity of every table apparatus conveying under given speed is to proofread and correct one by one active conveyer (for example suction pump, propelling feeder etc.).Then the operator utilizes every active conveyer of these correction value to provide some raw materials required speed.The operator suitably is provided with timer and starts production process subsequently; Every active transfer equipment continuous firing is up to producing the timer stop signal.
One of them problem of this system is that speed that it has supposed every active transfer equipment is constant and can not correction up.And prior art also depends on the sort of discrete control system that is built in every production equipment.The portable module control unit that includes that has been found that non-delivery type now can be used for providing control more accurately in the explosive production process.
