Description
Technical field
The invention belongs to machinery fields, and in particular to a kind of blade tilt is adjustable and the dismounting of the reducing pitches of anti-skid wearable
Formula delivery pump helical axis.
Background technology
The screw delivery pump of conventional design uses the screw shaft structure of sizing constant pitch, and spiral shaft vane is by being welded and fixed
On helical axis, blade is non-dismountable, and blade pitch angle can not change and blade surface is smooth, the disadvantage is that due to spiral shell
It is fixed to revolve the space of delivery pump conveying material, and space is smaller, very sensitive to material, when screw delivery pump uses one section
After time, the winding that material easily occurs when helical axis rotates can not between partial material will be caused to be jammed in spiral shaft vane
Conveying is completed, influences normally to produce, it is unsmooth and the problems such as have little time discharge discharge occurs so that screw delivery pump actual fed energy
Power is far below its designed capacity.The excessive accumulation of material can also aggravate the abrasion of spiral shaft vane, the working life of shortening device,
When a jam does occur, yield is gently then influenced, power consumption, waste of resource, it is also possible to twist off helical axis, electricity can be burnt out when serious are increased
Machine causes great operating irregularity, is caused a significant threat safely to employee's life, and there are larger security risks.Work as helical feed
Pump work for a period of time after, need to carry out necessary cleaning to remaining material in screw delivery pump, to prevent big impurity or fibre
Dimension property impurity, which enters in machine, to be caused to block, but since the spiral shaft vane in the screw delivery pump of conventional design is welded to spiral
On axis, it is this design so that screw delivery pump be relatively difficult to clear up, staff cleaning when need using a large amount of manpower,
Material resources will also devote a tremendous amount of time, and labor intensity is big, greatly reduce working efficiency, and work as one section of helical feed pump work
After time, spiral shaft vane inevitably will appear the problems such as some either large or small similar blade wears are serious, but due to
Blade is that an entire area is welded on helical axis, as long as so a place, which goes wrong, must replace monoblock blade, this nothing
It is doubtful to cause largely to waste, and replacement process is troublesome, will take a significant amount of time.Due to the screw delivery pump of conventional design
The blade pitch angle of middle helical axis is immutable, can not be altered or modified between material and blade according to actual condition demand
Frictional force, cause screw delivery pump can not ensure when conveying different materials or a variety of change conveying operating mode under have it is preferably defeated
Send effect.In addition, during screw delivery pump conveys material, since spiral shaft vane is smooth, easily leads to material and exist
Slipping phenomenon occurs for blade surface, to the problems such as uneven material mixing, feed blocking occur, to substantially reduce spiral transferring
Send the working performance of pump.
Invention content
It is an object of the invention to defects present in the screw delivery pump helical axis for above-mentioned conventional design, provide one
Kind blade tilt is adjustable and the reducing pitches detachable delivery pump helical axis of anti-skid wearable.The present invention is used along material conveying side
It is become larger to spiral shaft vane outer diameter and screw shaft structure that helical axis pitch becomes larger, the conveying being stepped up between pitch
Space effectively reduces the plugging phenomenon of screw delivery pump；It, can be according to conveying object using spiral shaft vane tilt adjustment structure
The characteristic and operating mode of material need, and selection is adjusted to suitable blade pitch angle, change material and interlobate frictional force, more
Be conducive to the conveying of material；By the way of increasing groove and convex block in smooth blade surface, alleviates material and transporting
The slippery conditions occurred in journey so that material mixing is evenly and feed blocking phenomenon obtains a degree of improvement, enhances
The working performance of screw delivery pump；Using the side for welding the anti-wear rib of arc for being coated with wear-resistant material in smooth blade surface
Formula alleviates material in transmission process to the abrasion of blade, increases the wearability of blade, increases the work longevity of helical axis
Life；Using detachable blade construction so that blade installation dismantles and repairs very convenient, and greatly reduces blade
Difficulty is cleared up, labor intensity is significantly reduced, increases working efficiency.
The technical solution adopted by the present invention to solve the technical problems is：

One piece of blade starts, and inclination angle square is adjusted to be welded on the reverse side of odd number block blade and the front of even numbered blocks blade；First blade bottom
Two positioning fang platforms and three pairs of support plates are welded on seat, the internal diameter of first blade pedestal is identical as the diameter of rotary shaft, the
One blade base thickness is identical as first piece of vane thickness, and two positioning fang platforms are symmetrical in the axial direction of first blade pedestal
Heart face is welded on first blade base outer surface, and positioning fang platform height is 1/10th of first piece of vane thickness, fixed
There is a longitudinal cylindrical positioning through hole in the fang platform of position, positioning through hole is a diameter of to position 2/3rds of the fang platform cross section length of side, determines
Position through-hole will position fang platform and be penetrated through with first blade pedestal；Striker plate is welded on the outer surface of first blade pedestal and pastes
Together in first piece of blade bottom, striker plate cross-sectional shape is rectangle, and backgauge plate thickness is the 20 of first piece of vane thickness
/ mono-, highly 1/10th for first piece of vane thickness；Sealing ring is mounted between striker plate and first blade；Setting
Striker plate and sealing ring are to prevent that material leakage phenomenon occurs at regulation blade inclination angle；The structure phase of nine pieces of detachable blade assemblies
Together, size is different, and along material conveying direction, the outer diameter of every piece of detachable blade assembly becomes larger, and variation range is
The axial length of 240cm~370cm, every piece of detachable blade assembly become larger, variation range be 190cm~330cm, nine
The different detachable blade assembly of block complements each other to form spiral shaft vane structure；In blade tilt adjustment structure, tune inclines
Angle square is welded in blade surface bottom, and support plate is welded on blade pedestal, and groove is located on blade pedestal, the width of groove
Slightly larger than the width for adjusting inclination angle square, depth of groove is the half of blade base thickness, and center-pole is by being fixedly welded on support
Between plate, there are five through-holes on center-pole, and the angle of five through-holes between any two is 1 °, and center-pole, which passes through, to be adjusted on the square of inclination angle
Lateral cylindrical hole then can adjust square band movable vane piece in inclination angle to rotate by rotation, when blade tilt turns to required position,
Corresponding through-hole on the longitudinal cylindrical hole and center-pole adjusted on the square of inclination angle is passed through to coordinate constant inclination again using constant inclination angle screw
Angle nut will adjust inclination angle square to be fixed together with center-pole；Blade locating structure is by positioning groove, positioning fang platform and positioning spiral shell
Nail composition will position the positioning through hole in fang platform and rotation when detachable blade assembly is placed into the corresponding position in rotary shaft
Detachable blade assembly is set to link together with rotary shaft by positioning screw again after positioning groove alignment in shaft
Complete the positioning to detachable blade assembly；Have two symmetrical positioning grooves in rotary shaft, positioning groove width with
The diameter of positioning through hole in detachable blade assembly location structure in two positioning fang platforms is identical.
