Accompanying drawing 2 is rabbling mechanism enlarged drawings of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of inventing is further described in detail.
Shown in Fig. 1 Fig. 2 showed, pulverizer 1 entered head tank 14 by conveying fan 2, conveyance conduit 3, cyclone separator 4, linked to each other with connecting flange 5 between cyclone separator 4 and the head tank 14.The lower end of head tank 14 links to each other with the main frame barrel 11 that main-machine screw 10 is installed by main frame barrel flange 12, and main-machine screw 10 links to each other with main frame gear reduction box 22 on being installed in main frame shelf 23 and by electric cabinet 24 controls.Head tank 14 is installed in to be installed on the shelf 21, and the staving of head tank 14 is equipped with upper infrared inductor 15 and the next infrared inductor 13.Central rotating shaft 7 is equipped with in the centre of head tank 14, central rotating shaft 7 be installed in buncher, motor pulley, reductor belt pulley 18, cycloid speed reducer 17, the central rotating shaft fixed screw 16 installed on the shelf and be connected.Epimere at central rotating shaft 7 is equipped with spice bar 6, and hypomere is equipped with spice bar 6 and adds spice and the pressurized delivered mechanism that compressing tablet 9 combines with spiral expansion blade 8 and master screw.Match with main-machine screw 10 in the end of central rotating shaft 7.
Below main inventive point of the present utility model is set forth:
1, pulverizer 1: adopt special stationary knife herringbone design, cutting knife is one group of a slice, and parallel installation reduces cutting and impacts, and cutting stress is disperseed to make installation, gap adjustment and the regular maintenance of cutting knife stable rotation the convenience again simultaneously blade to both sides.Charging aperture has been done the increasing design, and discharge bucket adopts material collection and the conveying after the design of wind collection formula makes things convenient for blower fan connection and pulverizing.
2, conveying fan 2: done improvement on the basis of centrifugal blower, the air intake angle is amplified and blast pipe directly connects with the pulverizer discharge bucket, and the corresponding amplification of wind pipe reaches the effect of the incremental amount of decompression power, and the big noise of conveying capacity is relatively low.
3, conveyance conduit 3: adopt in the PE material conveyance conduit with the spiral reinforcement of steel wire, intensity height, easy for installation and can not produce the characteristics of noise.
4, cyclone separator 4: will be separated with the mixture of material by the air stream that pipeline enters, material is sent in head tank 14, air is discharged to reach effective separation purpose from central tube.
5, connecting flange 5: make taper design, last bore is identical with cyclone separator 4 outlets, following bore identical with head tank 14 openings (littler) than last bore, the tapering size is suitable with cyclone separator 4 lower body rotary wind sections, reaches not increase the purpose that device height makes things convenient for installation and maintenance again when prolonging the separator lower body.
6, spice bar 6: be divided into two parts up and down on function is used: spiral launches the part of blade more than 8 and is referred to as top, mainly be to mix the material in the head tank 14 4 blankings of thoroughly convenient branch cyclone separator, also, material launches blade 8 when mixing thoroughly for evenly entering spiral downwards, spiral launches the following part of blade and is referred to as the lower part, mainly be to add compressing tablet 9 with spiral expansion blade 8 and master screw to be used, when main-machine screw 10 inlet amounies are launched blade 8 and master screw when adding compressing tablet 9 feeding coals less than spiral, material will be compacted, the resistance that central shaft 7 rotation spirals expansion blades and master screw add compressing tablet increases exponentially, the latter half spice bar is mixed material under this situation, partial material can upwards play anti-material effect, does not destroy drive disk assembly to such an extent as to whole like this charging system resistance just can not increase exponentially, motor, head tank, spiral launches blade and central shaft etc.Spice bar 6 adopts with central rotating shaft 7 and is welded to connect, first spice bar should be chosen in master screw and add the terminal shaft of compressing tablet to downward half pitch (in the middle of the just terminal downward pitch), spice bar 6 is afterwards pressed spiral expansion blade 8 directions (equidirectional with spiral expansion blade) and is become 120 degree spaced apart around central rotating shaft 7, and spice bar 6 is 15～30mm (deciding according to the size of overall system and the material that is suitable for) with charging staving 14 gaps.The need of the long 150mm of surpassing of spice bar are done welding and are strengthened.
7, central rotating shaft 7: provide moment for spice bar 6, spiral expansion blade 8 and master screw add compressing tablet 9 in reinforced process.Spindle nose end and main-machine screw 10 distances should remain within 20～70mm during design and installation, and definite distance should be according to material and variant.
8, spiral launches blade 8: be used to collect the material that evenly gets off from top spice bar 6 and carry out once spiral downward extruding, make material density increase to following master screw to a certain extent and add compressing tablet 9 chargings and prepare.The shape that spiral launches blade 8 becomes spiral expansion, adopts electric welding to connect with central rotating shaft, during design and installation and head tank should stay gap, 3～5cm left and right sides so that instead when material pressure is excessive expect.
9, master screw adds compressing tablet 9: in close relations with main-machine screw conveying capacity and material situation, the spiral external diameter becomes 1: 1.2 with main-machine screw～and 1: 2 ratio makes, pitch be diameter 1/2～3/4 between, master screw adds compressing tablet will be 2～3 times pitch around the central rotating shaft total length.The front end (also being the front end of central rotating shaft) that adds compressing tablet 9 at master screw adopt double helix, a spiral plate (structural parameters that add compressing tablet with original master screw are identical) of adding up generally have only around the spiral of central rotating shaft about 1/4 and former spiral be welded in the same way symmetric position (front end of central rotating shaft radially with the master screw of former main body add the compressing tablet original position be separated by 180 spend).Effect is to increase downward pressure frequency, even charging and make the pressure balance in the reinforced process in order to avoid make the monolateral stressed generation skew of central shaft, head tank wiped by compressing tablet or main frame barrel flange produces damaged phenomenon, and serious meeting makes the central rotating shaft distortion or twists off.When master screw adds the compressing tablet design and installation and head tank should stay gap, 10～20mm left and right sides so that install and use.
10, the next infrared inductor 13 of head tank: be used to measure storing lower limit situation in the feed hopper, give switching value signal of computer of electric cabinet, unite use with PLC.
11, head tank 14: being used for the splendid attire material, also is to launch blade 8, master screw with cyclone separator 4, connecting flange 5, spice bar 6, central rotating shaft 7, spiral to add the critical component that compressing tablet 9 etc. is united the work of feeding in raw material.The tapering of lower body will be good between 70 °～40 °.
12, the upper infrared inductor 15 of head tank: be used to measure storing upper limit case in the feed hopper 14, give switching value signal of computer of electric cabinet, so that stop associate device such as special-purpose pulverizer and conveying fan etc., can use the application that this switching signal that provides is write complete machine according to actual process.
When the utility model uses, the power-on switch, temperature is adjusted to setting value, temperature reaches the setting value back and opens the conveying fan starting button, the conveying fan back 2 minutes starting pulverizers that turn round, reinforced to pulverizer, wait the interior storing of head tank to last main motor, the reinforced buncher opened in limited time, the equipment input is normally used.
