The continuous rolling and mixing machine consists of motor, speed varying system, material feeder, roller, ballast spring, planet gear train, discharge hopper, material loosening assembly, material homogenizing hood, double screw mixer, mixing blades and feeder part. The production process includes the pre-mixing and feeding of material with the double screw mixer, homogeneously dispersing to the mill, conveying the material with the material loosening assembly to the discharge port, continuous rolling and kneading the material with the roller driven with the planet gear train to revolve and rotate and final continuously discharging through the discharge port.
Description
One, technical field
The invention belongs to the core key equipment in the powder ammonium nitrate explosive serialization production process.This machine has creatively solved the difficult problem that the serialization of powdery rolling is produced.
This machine adopt safe and reliable continuous wheeled roll the rubbing principle to number of chemical materials such as industrial ammonium nitrate, properties-correcting agent, oil phase, specialist additive, ultra-fine wood powders at normal temperature---fully roll, crumple, mix, make the dynamic variation of multiple compound generation physics continuously in specific ratio and order under the temperature of 115 degree, multiple compound molecule forms special array pattern, and molecular lattice structure reaches specific requirement.The fineness and the water content of medicinal powder reach required ratio simultaneously.
Two, background technology
In the production technique of industrial explosive material industry ammonium nitrate powdery class explosive, rolling is the manufacturing procedure of one key, and it is most important that the interior scientific research personnel of industry does not have powder time this operation of evidence, generally believes it is irreplaceable.So the ammonium nitrate Operating Condition of Powder Explosive Production still adopts old-fashioned wheel roller production so far, close machinery half manually, decades are unalterable.This equipment volume is huge, and production efficiency is low, can only discontinuous production, and non-cutting time is long, rolling and mix and produce continuously, explosive property relies on artificial the adjusting, is difficult to grasp.Need there be operator the production scene, and potential safety hazard is big.Working environment is poor, and is big to the healthy harm of operator.
Three, summary of the invention
For a change this backward situation, I scientific research personnel of company has creatively invented---the powder type explosive continuous grinding and mixing machine.The existing the problems referred to above of old-fashioned interruption wheel roller have thoroughly been solved.This device structure as shown in Figure 1.Mainly constitute by parts such as (1) motor, (2) mechanical variable speed system, (3) feeder, (4) milling roller, (5) ballast spring, (6) planet circular system transmission system, (7) discharge bucket, (8) combination loose metal assembly (as Fig. 2), (9) homocline cover, (10) twin screw mixing machine, (11) compound hybrid blade, (12) feeders.Pan mill and sidewall are equipped with the chuck that can lead to steam, make Working environment guarantee required temperature.Feeder (12) is sent spice under the vibration force effect in the hopper of twin screw mixing machine (10) equably, and two screw rods of twin screw mixing machine are oppositely with the speed running, and blade is staggered, and spice is carried out premix and sends to.Feeder on the main shaft (3) pushes main frame with spice and drops on the homocline cover (9) subsequently, and main shaft is with the rotational speed of 10-60r/min, and spice is along circumferentially scattering equably and dropping on the pan mill under action of centrifugal force.Slave type combination loose metal assembly (8) is fixed on the ballast rotor and with main shaft and revolves round the sun, and each loose metal blade is progressively loose and turn over to mill disc center discharge port and to send with the spice on the mill disc, and the angle of adjusting vane can realize regulating the purpose of spice flow velocity.Milling roller (4) is fixed on the ballast rotor and is driven by planet circular system transmission system (6) realizes revolution and rotation, to the rubbing of milling continuously of the spice on the mill disc, and fluctuates with the thickness difference of medicine layer.The ballast spring that places the alignment of shafts produces a downward preload pressure reaching the enough big useful load of each roller to roller all the time, and increases with the increase of medicine layer thickness.Spice falls into one deck to proceed to mill by the mixing of milling fully is back by discharge port on mill disc, to reach required milling efficiency, is discharged by the bottom discharge mouth at last, finishes the mixing production process of milling.
The innovation of this machine maximum is to have realized milling the mixed processes continuous automatic production, can realize whole piece powder ammonium nitrate explosive production line Long-distance Control, and the production scene does not need operator, has eliminated potential safety hazard.Simultaneously, owing to adopted the ballast spring to produce equivalent gravity loading, roller and relevant component volume weight reduce, and equipment volume reduces greatly.Owing to realized serialization production not needing subsidiary operation time, production efficiency significantly improves.Because production process does not have artificial intervention, all fronts whole-process automatic control is so the finished product explosive property is stable.Can predict this machine must become the leading equipment of the quick-fried industry powder ammonium nitrate explosive production of the people from now on and replace old-fashioned wheel roller comprehensively.
Four, description of drawings
The drawing explanation of accompanying drawing 1: this figure is the front projection figure of vertical grinding and mixing machine, by seeing among the figure that material adds (10) twin screw mixing machine by (12) feeder and is mixed into the mixed main frame of stone roller through (11) hybrid blade.Material gets rid of around the main frame coaming plate from (9) the homocline cover in the main frame, fall the mill disc outer ring, the movement locus that stirs gradually to open spiral-line that the loose metal assembly is made up in roll and (8) of warp (4) milling roller comes out to enter into next operation from (7) discharge bucket, and whole process is for being back to back.
The drawing explanation of accompanying drawing 2: this figure is the stretch-out view of (8) combination loose metal assembly in the accompanying drawing 1, by seeing among the figure: this combination loose metal assembly is made up of 25 scraper plates and a scraper arm, each scraper plate all can be adjusted up and down by the mode of shimming, and the rotation setting range at 30 ° of angles shown in the figure is arranged.The movement locus of material in the stone roller machine, the residence time and with the gap of mill disc respectively by the array mode of scraper plate, with the cumulative thickness decision of the angle and the pad of longitudinal axis.
