Description
Technical field
The present invention relates to vertical shaft type impact crusher, the more particularly to big minor adjustment of vertical shaft type impact crusher upper feeding mouth
Method.
Background technology
Vertical shaft type impact crusher, it is mainly used in the materials such as building stones, ore and crushes.Vertical shaft type impact crusher includes machine
Frame, motor, motor rack, top, rotor, middle part, spindle assemblies, pulley assembly, bottom etc..Main frame top is provided with charging
Bucket, feed hopper have simple two kinds of bucket and overflow downcomer, for accept Belt Conveying can broken material or other means conveying can
Broken material.Material enters the rotor center region of rotation at a high speed from feed hopper bottom centre bore, and material is thrown in rotation to rotor at a high speed
Onto middle part inwall, material and the wear-resisting anvil or stone lining of the installation of middle part inwall hit, and reach crushing effect.In overflow downcomer bottom
The heart has the adjustable plate that can adjust aperture size, and periphery is provided with transfer window, when reducing overflow downcomer bottom centre hole size, comes
Material will be accumulated in hopper, after reaching a certain height, will enter the strike region of rotor periphery from peripheral overflow mouth beyond part.
The material impacting that the material that rotor is dished out will fall with peripheral overflow, portion of energy is saved, remains to reach identical crushing effect,
For the operating mode based on shaping, spillway discharge can reach more than 35%.
In order to reach optimal crushing effect and control the generation of dust, flow velocity, the flow of pan feeding need to be controlled.This
What control was mainly realized by the size and its annex of feeding mouth.Prior art control method has:1st, center hole size is changed not
Same feeding mouth annular slab;2nd, lift backgauge adjustable plate is set above or below feeding mouth, such as the He of patent 200920208090.8
Patent 201110070141.7;3rd, set horizontal expansion type movable regulating plate below feeding mouth, as patent ZL200620157001.8,
201020666561.2,201220356968.4,201520428537.8 etc..
In above prior art, to the big minor adjustment of feeding mouth, or need to shut down and change ring flat-plate, adjustment rising-falling tone
Save plate height, angle;Or carry out manually adjusting horizontal expansion type activity adjustment by manually observing blanking state in operation
Plate.Once adjustment is suitable, generally no longer operation changes.But the operating mode of supplied materials changes very greatly, e.g., during startup and shutdown,
There is no material entrance, supplied materials can decrease or increase in operation, in a kind of dynamic change, for certain failure or inspection in operation
Survey maintenance to require, can control or stop being fed.In feed changes, some effects have harmful effect:Less can not without material or material
During blocks central aperture, negative pressure caused by the rotor of rotation can suck large quantity of air at a high speed, then be overflowed by top or bottom, produce
A large amount of dust is excessive;Centre bore does not shrink when material is few, and stream bias enters rotor, and rotor imbalance produces larger vibration, uneven
Abrasion, reduce bearing, oil sealing life-span.If eliminating above harmful effect, need it is artificial it is on duty is adjusted in real time, manually into
Originally, management cost is all very high.
The content of the invention
In order to adapt to the dynamic change of vertical shaft type impact crusher supplied materials, the harmful effect of supplied materials dynamic change is eliminated, is reached
To the purpose of timely automated regulation feeding mouth size, the invention discloses vertical shaft type impact crusher upper feeding mouth to automatically adjust
Method.
The technical solution adopted in the present invention is vertical shaft type impact crusher upper feeding mouth Automatic adjustment method, to pass through
Level detector collects the height value of pan feeding material heap, and logic controller is sent to material position higher than the state of setting height shrinks adjustable plate
Command signal, logic controller send the command signal of expansion adjustable plate to material position less than the state of setting height.
Particularly:Material stack height in material bin is perceived by level detector, sets the fluctuation range of material stack height.Work as heap
When material is higher than setting high-order, controls adjustable plate under feeding mouth to open, increase feeding mouth, increase central blanking, it is low to feed height
No longer opened in a setting high position;When windrow is less than setting low level, controls adjustable plate under feeding mouth to reduce, reduce feeding mouth, subtract
Few central blanking, to feed height higher than setting low level, it is limited in feeding mouth and completely closes.Described adjustable plate can use existing
There is the either type of technical merit expansion type adjustable plate.
Level detector collects the height value of pan feeding material heap, can be the instant numerical value or material stack height of material stack height
The upper limit, limit switch amount.
As optimal technical scheme:The level detector of material stack height is perceived, there can be several ways:
Level detector measurement form can be radar surveying, ultrasonic measurement, grating measuring, the measurement of microwave grid, infrared ray survey
The non-contact measurements such as amount, laser scanning can also be the contact type measurements such as tuning fork measurement, blocking rotary type measurement, Weight type measurement.
Specifically:Setting to level detector, one kind are level sets, the setting height(from bottom) scale in barrel side wall, with spiral shell
The modes such as bolt installation, pin installation, clamping, absorption installation fix level detector, the level height of level detector are moved with manual operation initial stage
Position is spent, high-value and low-value is met crushing system requirement.One kind is radar type, and signal detection is sent with level detector
Material stack height, high charge level and low material position are set by logic controller.
Level detector signal enters logic controller, and logic judgment, material stack height are carried out according to setting value by logic controller
Higher than setting high-value, driving adjustable plate makees expansion action, is less than setting value to material heap signal;Material stack height is low less than setting
Place value, driving adjustable plate make contractive action, are higher than setting low-value to material heap signal;
Specifically:Logic controller, there can be logical operation capability chip and not possess logical operation capability
Logic controller that element is combined into or do not possess that the element of logical operation capability is combined into have logical operation energy
The logic controller of power or do not possess that the element of logical operation capability is combined into have logical operation capability with not having
The chip portfolio of standby logical operation capability into logic controller, can be that hardware controls can also be software control.
