Description
Technical field
The present invention relates to the ship unloaders of screw ship unloader, more particularly to vertical spin conveying.
Background technology
Screw ship unloader is as the main application apparatus in ship unloaders, the ship-discharging operation applied to various materials.Now
It is relatively broad using the conveyor apparatus of vertical spin pipe in ship unloaders, but abrasion is also more serious, is that screw ship unloader loses
The main reason of effect or failure.
Wherein, the life-span of spiral conveying tube is on the one hand relevant with the shape of dry scattered material, also with the shape and chi of helix tube
It is very little closely related, high-abrasive material manufacture and scientific and rational design spiral shell are only selected according to the fundamental characteristics of bulk material
Rotation shape and size could design and produce the spiral ship unloaders of function admirable.
The helix tube and helical blade of existing screw ship unloader use cylindrical tube and cylindrical spiral substantially, but
In work, with being constantly delivered up for material, the resistance of conveyer constantly becomes big from the bottom to top, and the material on top can be under
Hardened shape is formed under the pushing of the material in portion, thus, the energy consumption of whole ship unloaders just increases, and easy putty.On the other hand, with
Friction and the increase of power, temperature rise is higher in whole helix tube, and the service life and use state to ship unloaders can all produce
Harmful effect.Meanwhile the abrasion of the working component such as tube wall also can accordingly increase, particularly conveyor screw, tube wall and centre are propped up
Bearing is held, turns into the industry conveying worm existing technical barrier always.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of non-constant section spiral ship unloading equipment, overcome conveyer and exist
Constantly become big resistance problem and material hardened problem when upwards.
Therefore, the present invention uses following technical scheme：
The spiral ship unloading equipment include running part, dispenser, helical axis, outside helical blade and helical axis on helical axis
Pipe, it is characterised in that the helical axis outer tube constantly becomes big conical pipe for diameter from the bottom to top, and the helical blade is and cone
The cone spiral vane constantly to broaden from the bottom to top of shape pipe adaptation.
Further, the spiral shaft diameter is constant.
Further, the bottom connection dispenser of the conical pipe, top is connected by flange, bearing assembly and power transmission shaft
Connect, the power transmission shaft is connected with motor.
Further, the axis angle that the outer tube wall of the conical pipe deviates helical axis is 1-15 °.
Preferably, the axis angle that the outer tube wall of the conical pipe deviates helical axis is 2-8 °.
It is furthermore preferred that the axis angle that the outer tube wall of the conical pipe deviates helical axis is 4.5 °.
Present invention also offers a kind of ship unloaders, and it is provided with foregoing non-constant section spiral ship unloading equipment.
The conical pipe and cone spiral vane that the non-constant section screw ship unloader of the present invention uses, internal relative wear is small,
The abrasion of blade also reduces simultaneously, moreover, reducing the resistance in material conveying, energy consumption reduces, and the possibility of putty is also significantly
Reduce.The present invention has started the precedent of cone-type spiral delivery pipe, ingenious in design, reduces cost, extends conveyer and unloading
The service life of machine.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of non-constant section spiral ship unloading equipment of the present invention.
Fig. 2 is the ship unloaders schematic diagram of the present invention for including non-constant section spiral ship unloading equipment.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Embodiment one：
Refer to the attached drawing 1.Accompanying drawing 1 is a kind of schematic diagram of non-constant section spiral ship unloading equipment of the present invention.Conveying worm
Chief component for running part 1, dispenser 14, helical axis 7, helical blade 6 and helical axis outer tube on helical axis 7
5。
The helical axis outer tube 5 constantly becomes big conical pipe for diameter from the bottom to top, and the helical blade 6 is and conical pipe
The cone spiral vane constantly to broaden from the bottom to top of adaptation, the bottom connection dispenser 14 of the conical pipe 5, top passes through method
Orchid 4, bearing assembly and transmission axis connection, the bearing assembly include bearing housing 2, bearing block 3, the transmission, and 1 and motor
15 connections, the motor are the motor of conical pipe vertical spin conveying.Drive that dispenser 14 works for feeding spiral horse
Up to 8, the feeding auger motor 8 realizes the rotation feeding to dispenser by gear train 10 and floating bearing 11.The feeding
Auger motor 8 is arranged on a peach-shaped case 9, and the bearing group such as gear train 10 and floating bearing is arranged in peach-shaped case 9, the taper
Pipe is also in 9 times setting taper peach-shaped case hypomeres of peach-shaped case.
The conical pipe is provided with taper external spiral 13 on the tube wall of bottom, for material back pressure and do not influence tube wall
Equipment operation.
In addition, the diameter of helical axis 7 is constant, the helical axis 7 is the common constant circular shaft of diameter.
In the present embodiment, the axis angle that the outer tube wall of the conical pipe deviates helical axis is 1-15 °.
Preferably, the axis angle that the outer tube wall of the conical pipe deviates helical axis is 2-8 °.It is furthermore preferred that the taper
The axis angle that the outer tube wall of pipe deviates helical axis is 4.5 °.Angular range work within the range it is more stable, through overtesting and
Job result shows, the more common conveying efficiency high 20% of material conveying effect in the angular range, and lower power consumption 10%.
Also, cone-type spiral pipe relative wear is small, cone spiral vane relative wear is small, and putty situation substantially reduces, whole so as to extend
The machine life-span.
Embodiment two：
Working process and principle of the invention are explained：
The tubular outer tube diameter of circular cone is small in the big bottom in top, is often fixed in frame, is considered as inactive state；Inside spin（Equally
In the small shape in the big bottom in top）Then rotated by direction as shown.When spiral rotating, push effect and material due to helicoid
With the double action of the frictional force of helicoid, material will follow spiral conveying tube to rotate together, when the rotating speed of helical axis 7 carries
Gao Shi, the rotating speed of material also improve therewith.When rotating speed reaches certain value, centrifugal force that material is subject to will overcome spiral blade face
Caused frictional force, material radially slide to outer tube wall, and because outer tube wall is tapered, therefore material is acted on upwards by tube wall
Component be more than 0, and the component that isometrical outer tube wall acts on upwards be equal to 0.
And as rotating speed further improves, due to the effect of centrifugal force, material is crushed on outer tube wall, and material is by pipe
The component that wall acts on upwards and angle of taper are proportional, proportional with the pressure suffered by material.When outer tube wall taper is certain
When, the more big upward component of pressure is also bigger, and now on the one hand outer tube wall prevents frictional force caused by material material along pipe
Wall glides（Grab wall phenomenon）, material is on the other hand driven along helicoid upward sliding（Drive phenomenon）.
Spiral is on some rotating speed（In the case that structural parameters are fixed）, material neither can glide nor move up, this turn
Speed is that vertical spin delivery pipe produces the theoretic lowest limit rotating speed of improving material.
When outer tube tubular using circular cone, because inner cone tube wall provides a upward component to material, so in structure
And conical pipe is low compared with equal pipe lowest limit rotating speed in the case of other specification identical, that is to say, that obtains same unloading effect
The power of rate is small.
Embodiment three：
A kind of ship unloaders, including the non-constant section spiral ship unloading equipment as described in embodiment one or embodiment two.
