Background technology
Be known as the disintegrating apparatus of percussion grinder in the extensive use of wheat flour milling industry.Percussion grinder is by casing, and rotor part, stator component and motor form.Wherein, rotor part comprises rotor wheel shell, is fixedly connected with disk rotor dish on rotor wheel shell, and at least 3 circle rotor pins are installed on rotor disk, the cross section of rotor pin is square, and the number of rotor pin is generally at least tens (sum is no less than 50).Rotor hub, rotor disk and rotor pin composition rotor part.
Stator component comprises the disc stator disc on casing cover plate, casing cover plate, the sub-pin of at least 3 delineation of installing on stator disc, and the cross section of stator pin is square or circular, the number of stator pin is no less than 100.Between rotor pin and stator pin, be provided with gap.
The material particles that percussion grinder clashes in described gap by the rotor pin of installing on the rotor disk of High Rotation Speed reaches pulverizing object.According to basic principle of dynamics analysis, the technological effect of shock depends primarily on pin and is knocked the size of the relative velocity of material particles.Because rotor pin is directly to clash into material particles, and the effect of stator pin is to stop that material particles along the circumferential direction moves, so rotor speed is higher, clash into technological effect better, gap between rotor pin and stator pin is less, the effect that stator pin obstacle material particle along the circumferential direction moves is more remarkable, and the technological effect of shock is better.Analyze in theory, the moment that each rotor pin approaches each stator pin can form once shock strongly.Calculate like this, in an impact disintegrating mill casing, the strong shock of middle formation per second reaches 30～600,000 times.Therefore, compare many advantages such as that percussion grinder has is simple in structure, crushing function is powerful, price is cheap, and installation and maintenance are convenient, and energy consumption is low and widely applicable with the size reduction machinery that roller flour mill is close with use occasion with most of functions.
but so high-frequencyly also certainly lead to a large amount of heat energy when strongly impinging upon crushing material, in addition, the rotor of High Rotation Speed throws away material, and material strikes casing inner wall and continuous operation strongly
motoralso can produce a large amount of heat energy.Above three thermal source comprehensive functions, usually make temperature that percussion grinder when work discharging opening place detects at 50 ° more than C.Have data to record, in wheat flour milling process, material to be machined temperature exceedes 50 ° of C and starts that flour edible quality is had to negative effect, reaches 60 ° of above flour protein sex change of C, and high temperature process progressively increases the weight of the negative effect of flour edible quality, so,
existingpercussion grinder
in process, causing material temperature rise is its maximum shortcoming.In addition, existing percussion grinder is motor direct-connection type, and rotor speed is identical with motor speed, and the crushing function of equipment and technological effect can not regulate and produce 100 decibels of above noises when equipment operation is also great shortcoming.
At present, wheat flour milling industry is also commonly used a kind of equipment that is known as entoleting machine both at home and abroad.The casing of entoleting machine is similar to percussion grinder with cover plate.The workpiece of entoleting machine is enclosed respectively and is made up of the runner of dozens of tubulose pin by former and later two disks, therebetween two by one.The wheel hub that install the center of runner hub disk is fixed on motor shaft.When equipment work, material enters runner by the circular hole on the charging aperture on cover plate and runner shroud.With 2900r/min(rev/min) runner of left and right speed rotation throws away material, and material is strongly clashed into when by tubulose pin present position, then clashes into casing inner wall, and then the discharging opening from casing is discharged.Because the wind-force of High Rotation Speed driven by rotating wheel and the impact of tubulose pin all make material particles in runner have all the time sizable circular motion speed, therefore make the relative velocity of tubulose pin shock material particles moment and the intensity of tubulose pin shock material particles significantly reduce, so existing entoleting machine clash into material particles have can partly kill insect that material contains and worm's ovum, shock after material temperature rise low, the advantage such as be free from side effects; But low its insecticidal effect that also causes of impact strength is not good enough.In addition, existing entoleting machine does not have conveying function, thus mostly will with the supporting system of carrying in malleation such as Roots blower in apply.High because of Roots blower price, energy consumption is high, and High Pressure and run up and usually cause oil seal failure, and and then causes the Frequent Accidents of motor bearings damage.Therefore, comprehensively analyzing existing entoleting machine has insecticidal effect not good enough, and investment is large, the high shortcoming of energy consumption and accident rate.

The present invention has following beneficial effect:
The coefficient of heat conduction of common used material is respectively: copper 401, aluminium 250, iron 84～90, air 0.03.According to above-mentioned record, casing cover plate under stator component of the present invention is made with aluminium alloy casting, outside casing cover plate, direct pouring goes out helical tank, add cover plate tank cover plate, more than stator component increases twice to the existing like product of Area Ratio of the cooling water in cover plate tank and the heat radiation of cover plate outer air.Casing cover plate inner side is except holding together with part the toroidal cavity of stator column pin nut all fits tightly with stator disc, and the contact area rate prior art increasing of casing cover plate and stator disc is twice above.The heat-conducting padding plate of manufacturing with sheet copper or thin aluminum sheet is set in the space between casing cover plate inner side, casing cover plate and stator column pin nut end, while ensureing that stator disc is fixed on casing cover plate, together with casing cover plate medial surface, heat-conducting padding plate fit tightly with stator pin top three, prior art stator pin top is become thermal energy conduction into mode by copper or aluminium sheet conduction to the mode of casing cover plate by air, make the stator pin that gathers a large amount of heat energy directly at least improve hundreds of times to the efficiency of casing cover plate heat by conduction energy.Meanwhile, in stator component heat abstractor, stator pin is heat energy carrier, and the heat-conducting padding plate of setting up also plays the effect of the radiator of heat energy carrier.The heat energy accumulating on stator pin conducts to heat-conducting padding plate rapidly, has accelerated heat radiation process.In the space between casing cover plate and stator disc, the object of filling copper wire aluminium wire or copper aluminium fragment (being the replacement form of heat-conducting padding plate) in the space between fixed stator pin nut is that metal charge can be contacted with stator disc with stator pin, receive the heat energy of stator pin and stator disc, can contact with casing cover plate again, thermal energy conduction, to casing cover plate, then is evacuated away by cooling water.The function of metal charge is identical with heat-conducting padding plate.This measure is used proper, can make stator component heat abstractor effect improve more than 50%.
Because it is the decades of times of stator pin that rotor pin clashes into the frequency of material particles, so rotor pin must be the highest heat energy carrier of temperature of the present invention.The present invention manufactures main shaft with seamless steel pipe, and the heat energy conducting by rotor disk with cooling water evacuation rotor pin.In addition, it is L shaped strip fan blade that the present invention installs 4～16 sliver transvers sections at rotor disk reverse side, and opens a rectangle wind-supplying mouth at chassis backplane near the position of main shaft.When the present invention works, fan blade on the rotor disk of High Rotation Speed can suck bottom of shell the cold air of the air at room temperature at wind-supplying mouth place or special preparation, and forms cold wind (gathering in any case the temperature of rotor pin of the heat energy of strong shock certainly apparently higher than room temperature) and strongly blow on the nut of fixed rotor pin.Because the position of the most close generation thermal source of rotor disk of nut and periphery (referring to directly clash into the rotor pin working position of material particles), so inevitable quite remarkable with the heat radiation function of high speed cold wind nut and rotor disk.
The present invention in the spiral case arranged outside of casing casing tank.Enter the well water of casing tank or running water or the temperature the highest degree more than 30 only throughout the year through cooling tower recirculated water after treatment, the cooling water uninterruptedly flowing through can be controlled at the temperature rise of the spiral case inner side contacting with material in 10 ° of C, and existing percussion grinder clash into after the temperature of material at least at 50 ° more than C, therefore the present invention is by the spiral case arranged outside casing tank at casing, in most of the cases can not only material particles clash into casing inner wall produce heat energy evacuates away, and can by moment contact reduction material particles temperature.
In sum, the present invention takes casing cover plate and the heat-conducting padding plate of the material making apparatus high with the coefficient of heat conduction; Go out cover plate tank in the top casting of aluminum casing cover plate, make main shaft and make casing tank and logical cooling water in cover plate tank, casing tank and main shaft hollow pipeline in the spiral case outside of casing with seamless steel pipe; Increase volume and the surface area of radiating element (casing cover plate, main shaft and casing), increase the contact area between radiating element and heat conduction member, replace air transmitted mode by metal conduction mode, pass into the chilled air cools rotor part of air at room temperature or special preparation to casing, equipment rotor and motor are separated etc. to method and reach the object heat energy is evacuated away in body of the present invention.Device structure and principle Analysis press proof machine are tested and are shown, when the present invention works, that detects at discharging opening place is knocked temperature of charge than the low 10 ° of C～20 ° C of existing percussion grinder.If the temperature that passes into cooling water is controlled to 30 ° below C, be enough to the temperature of material to be machined to be controlled at 50 ° below C.Therefore adopt the present invention can make that the quality of cereal machining production line output finished product obviously improves, finished product edible quality is obviously improved, main shaft water flowing is cooling simultaneously separates with rotor part is extended the service life of main shaft and motor bearings at double with motor, and equipment operational failure rate significantly reduces.In addition, above-mentioned measure is also dwindled the cavity that can cause sympathetic response and the amplification sound between stator disc and casing cover plate more than 80%, adds the sound absorption of cooling water, and when the present invention is turned round, noise ratio prior art obviously reduces.After motor separates with rotor part, the belt pulley by the different speed ratios of adapted or sprocket wheel can change the rotating speed of rotor part, reach the object of controlling operation effect of the present invention.Configure a set of arrangements for speed regulation in the occasion that has specific demand to the present invention, can make the present invention there is the function of the at random conditioning equipment operation effect equal with existing roller flour mill, the biggest obstacle of having eliminated percussion grinder replacement roller flour mill, its economic benefit and social benefit are very remarkable.
Basic identical with the air-cooled percussion grinder of water-cooled for the general structure of the present invention of desinsection and operation principle, difference is only being done disinfesting machine with must be the gap increase between rotor pin and stator pin, and rotor speed is suitably reduced.Because the speed that makes material circular motion that stops stator pin significantly reduces (speed that approaches stator pin material just approaches zero rotating speed), impact strength of the present invention is much larger than existing entoleting machine, so the gap between rotor pin and stator pin is being increased to behind about 5mm, regulating rotary rotor speed can make the indexs such as insecticidal effect of the present invention and energy consumption all obviously be better than prior art.(insecticidal effect of the material of same equipment processing variety classes and state has very big-difference, so cannot list clear and definite rotary speed data).The cooling measure that the present invention takes on stator component, rotor part and casing be enough to ensure be knocked after material temperature rise be starkly lower than existing entoleting machine.Good disinsection effect and to be free from side effects be the large advantage of the present invention one.Be used in the present invention of positive Pressure Transportation System, oil sealing must be installed in casing and feed pipe and main shaft contact position.Because being subject to significantly to reduce through the cooling water heat radiation of spindle cavity and rotor speed the impact of these two factors, oil sealing extends service life greatly, and the accident rate of leaking material reduces, and main shaft and motor are separated and made accident impact face and loss be worth significantly reduction.In addition, theory analysis and test all show, rotor disk reverse side is installed fan blade and open wind-supplying mouth and can not only evacuate rotor part heat energy on casing, and can make the present invention have certain conveying function.The area that suitably increases fan blade quantity and fan blade windward side, can make its conveying function increase to the degree that can replace Roots blower.The present invention without Roots blower is with the obvious advantage at aspects such as reduction equipment investment and energy consumption and streamlining managements.
