Description

A kind of novel feeder
Technical field:
The utility model relates to a kind of coal supply technology, especially a kind of novel feeder.
Background technology:
Run into the stifled storehouse situation that reasons such as feed bin obstruction, coal dust caking cause in use through regular meeting for the feeder of installing under the finished product silo of GENERAL TYPE colliery, particularly in the winter time temperature to be lower than 0 situation when spending more obvious.Present original solution is that feeder comes Vibration Storage bin to carry out blanking with the way of feed opening linkage section under the feed bin with knocking, each feed opening stop up all needs 4-6 people to take turns to knock could smooth blanking.This mode of operation not only causes workman's intensive work, also has bigger danger, simultaneously because bang feed hopper and feeder etc. all cause bigger infringement.
Because feeder is in long-time load running, each parts of feeder need maintenance in time or change, but in order to guarantee staff's safety, could overhaul by closed shutter in the time of must waiting until not blanking of feed bin, because feeder produces coal to successional, as long as there is the coal grain in the feeder deflector chute, gate just can't be closed fully, and the parts that change the replacing of feeder urgent need can not in time be overhauled or change.Present terms of settlement is just can carry out the feeder service work when waiting feed bin not have material or obstruction, and the coal mine equipment service work can not timely and effectively be carried out.
Because feeder is when work, be in unwatched state, evenly whether the blanking of readymade coal, the blanking situation of fine coal can only be carried out guestimate by monitoring, have only and just go the cleaning mediation when feed bin stops up by the time, in case the mediation cleaning work will be very loaded down with trivial details when forming coal cinder knot plate, caking phenomenon, the effort of taking a lot of work.
Summary of the invention:
The purpose of this utility model provides a kind of novel feeder of automatic mediation, automatic control gate, it has overcome the present common shortcoming that exists with feeder, the purpose of this utility model is to realize like this, it is by feed bin, air bubble, PLC automatic control box, LOAD CELLS, hydraulic gate, Hydraulic Station, feeder, hydraulic motor frequency-variable controller, feeder drive motor frequency-variable controller, is formed by connecting for bridge case, PLC auto mat, several air bubbles are installed in feed bin, feed bin is connected with feeder, and hydraulic gate is installed in the middle of it; The number table scale retransmits sensor and is contained in the feeder belt respectively near feed opening and middle part, and tachogenerator is installed on feeder head roll end; Air bubble is connected with the PLC automatic control box, the PLC automatic control box is connected with supplying the bridge case by the accumulative total pulse signal-line, be connected with tachogenerator by the speed signal line respectively for the bridge case, be connected with LOAD CELLS by the weight signal line, LOAD CELLS is connected with the integrator of weighing; Adding up pulse signal-line simultaneously is connected with the PLC auto mat, the PLC auto mat is connected with hydraulic motor frequency-variable controller, feeder drive motor frequency-variable controller respectively, the hydraulic motor frequency-variable controller is connected with Hydraulic Station, and feeder drive motor frequency-variable controller is connected with tachogenerator.
The utility model adopt the feed bin mediation with air bubble as feed bin cleaning mediation equipment, feeder installs LOAD CELLS additional to carry out material or coal cinder whether stifled storehouse is judged, utilizes the hydraulic gate electromagnetic valve to carry out the closing gate action simultaneously.This device can detect whether there is material in the feeder deflector chute, can utilize load cell signal to open air bubble simultaneously and work automatically.Can close the feeder hydraulic gate automatically simultaneously when not having material, convenient work workman overhauls and changes equipment component.This device can alleviate staff's labour intensity greatly, and the danger that brings when reducing manual operation improves the work efficiency of equipment with uncertain.Can accomplish simultaneously the automatic management of feed bin cleaning.
Application process of the present utility model: will count table scale and retransmit sensor and be contained in the feeder belt respectively and below feed opening and middle part, be used for measuring feeder guide storehouse, 1 tachogenerator is installed on the head roll end is used for measuring belt speed, the weight of material in the linkage section, the weight signal that LOAD CELLS measures (20m electric current) passes in the integrator of weighing, after its built-in micro controller system processing, to add up impulse singla is transferred in the PLC controller, the PLC controller is told 2 groups of signals and respectively impulse singla is passed to the electric machine control of Hydraulic Station pump for the start and stop of control hydraulic gate, provides signal by the PLC programming and carries coal supply machine operation control frequency converter for the start and stop of control feeder.The accumulated signal that the integrator of weighing sends passes to the start and stop order that is used for the control air bubble in the air bubble control box.
Workflow: after the feed bin blanking, inhomogeneous as blanking, the LOAD CELLS that is positioned at the feeder bottom passes to the integrator of weighing with current signal, the integrator of weighing sends impulse singla and gives material top air bubble PLC control box according to presetting weight of material, starts its PLC preset program by the air bubble control box and opens relevant air bubble in order and carry out the material block clearing.Reach the purpose of automatic block clearing.The weight of material that records when LOAD CELLS is during less than setting value, can think that this moment, material stopped up, weigh integrator to the start and stop of the electric machine control that impulse singla is passed to the Hydraulic Station pump for the control hydraulic gate, can reach the purpose of automatic closed shutter with convenient maintenance.The user can rule of thumb be worth and sets the LOAD CELLS preset value, when the LOAD CELLS observed reading when setting weight of material, can think that feed bin stops up.Carry out block clearing or closed shutter work this moment, can change air bubble control case into manual control when needs overhaul, and Hydraulic Station and feeder control frequency converter are set at automatic work.On the contrary, with air bubble control box design automatic mode, Hydraulic Station control frequency converter is set at manual control during as the need block clearing.
