Abstract
The utility model belongs to the technical field of coal bunker dredging and particularly discloses a ring type device capable of loosing a coal bunker, which comprises a coal bunker in front of a furnace and is characterized in that a plurality of annular loosing devices are arranged in the coal bunker in front of the furnace. Pull rods on the annual loosing devices are connected with an oil cylinder connecting rod of an oil cylinder, loosing sheets are fixed on the pull rods, and an oil pipe connected with the oil cylinder is connected and communicated with an electromagnetic reversing valve in a hydraulic oil station. The ring type device capable of loosing the coal bunker is reasonable in structural design and ingenious and novel in conception, automatically monitors coal supplying situation of the coal bunker in front of the furnace, can start up automatically when coal supplying is interrupted, conducts dredging in time, and stops automatically when coal feeding is unblocked, thereby guaranteeing that coal supplying of an raw coal bunker is smooth.
Description
(1) technical field
The utility model belongs to the bunker dredging technical field, but particularly a kind of ring type loose coal bin device.
(2) background technology
The stokehold coal bunker is a main auxiliary facilities of coal-fired station's boiler.But just on this facility, existing insoluble for many years problem---the stokehold coal bunker stops up.Especially it is big to work as moisture in coal, and ash content through regular meeting arch camber, chute blockage takes place for a long time.The loose machine of traditional coal bunker is an external rapping dredger; Moisture in coal hour; External rapping dredger can play certain effect, but when the moisture in the coal is big, external rapping dredger DeGrain; And sometimes play opposite effect, the more difficult mediation of rapping more.The lighter causes the coal supply amount to reduce, and the unit generation amount descends, and weight person causes coal supply to stop, compressor emergency shutdown, and What is more causes coal bunker spontaneous combustion, flue gas to play a reversed role to burn feeder, cause industrial accident.Seriously influenced the ordinary production of power plant.Still there is not at present ripe running device to get the nod.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, but provide a kind of rational in infrastructure, operate steadily, the ring type loose coal bin device of safety and stability.
The utility model is realized through following technical scheme:
But a kind of ring type loose coal bin device; Comprise the stokehold coal bunker; It is characterized in that: be provided with several annular scarfieies in the coal bunker of said stokehold, the pull bar on the annular scarfier is connected with the oil cylinder connecting rod of oil cylinder, is fixed with loose sheet on the pull bar; Connecting the oil pipe of oil cylinder is connected with solenoid directional control valve in the hydraulic oil unit and communicates; The bottom of stokehold coal bunker is equipped with the Weighting type belt coal-feeding machine, and the discharge nozzle place of Weighting type belt coal-feeding machine is equipped with the disconnected coal signal transducer that connects control box, and control box is connected with oil pump in the hydraulic oil unit.
The utility model is installed annular scarfier on the coal bunker of stokehold; And through the disconnected coal signal transducer perception medium cutout on the Weighting type belt coal-feeding machine or rate-of flow information less than setting value; Give control box through sensor with the information transmission; Realization reaches hole skewback plinth loose automatically, that eliminate chute blockage, canopy coal to the start-up control of annular scarfier, realizes loose purpose.
In the said hydraulic oil unit, oil pump is connected with solenoid directional control valve, is connected with electrical motor and oil filter on the oil pump, and annular scarfier adopts hydrostatic drive, operates steadily, and is safe and reliable, easy maintenance.
For realizing the firm installation of annular scarfier; Pull bar on the said annular scarfier is fixed on around on the stokehold coal bunker wall in one week through fixed card, can adjust loose sheet according to the angle of coal bunker, makes loose sheet as far as possible near the coal bunker inwall; Can play making an overall screening, not stay the purpose at dead angle.
The loose sheet of said annular scarfier adopts HSLA and resistant to corrosion stainless steel material to make, and guarantees structural strength, guarantees service life.
The installation of annular scarfier does not destroy the intensity and the running state of coal bunker original structure, and is rational in infrastructure, and good looking appearance is suitable for various feed bins supportingly, and equipment volume is little, and it is big that Applicable scope is installed.
The utility model reasonable in design, the novelty that is skillfully constructed, this device is monitoring stokehold coal bunker coal supply situation automatically; When occurring breaking coal, start mediation in time, the unimpeded back of coal supply auto-stop voluntarily; Guarantee that the run coal bin coal supply is unimpeded; Prevent to guarantee safety in production, alleviate workman's labor load because of sticking coal stops up break coal and coal spontaneous combustion problem.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model annular scarfier.
Among the figure, 1 stokehold coal bunker, 2 annular scarfieies, 3 oil cylinders, 4 oil pipes, 5 solenoid directional control valves; 6 oil pumps, 7 electrical motors, 8 oil filters, 9 Weighting type belt coal-feeding machines, 10 disconnected coal signal transducers, 11 control boxs; 12 fixed card, 13 loose sheets, 14 pull bars, 15 oil cylinder connecting rods, 16 hydraulic oil units.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises stokehold coal bunker 1; Be provided with several annular scarfieies 2 in the said stokehold coal bunker 1; Pull bar 14 on the annular scarfier 2 is connected with the oil cylinder connecting rod 15 of oil cylinder 3; Be fixed with loose sheet 13 on the pull bar 14, connect the oil pipe 4 of oil cylinder 3 and be connected with solenoid directional control valve 5 in the hydraulic oil unit 16 and communicate, the bottom of stokehold coal bunker 1 is equipped with Weighting type belt coal-feeding machine 9; The discharge nozzle place of Weighting type belt coal-feeding machine 9 is equipped with the disconnected coal signal transducer 10 that connects control box 11, and control box 11 is connected with oil pump 6 in the hydraulic oil unit 16; In the said hydraulic oil unit 16, oil pump 6 is connected with solenoid directional control valve 5, is connected with electrical motor 7 and oil filter 8 on the oil pump 6; Pull bar 14 on the said annular scarfier 2 is fixed on around on the stokehold coal bunker wall in 1 one weeks through fixed card 12; The loose sheet 13 of said annular scarfier 2 adopts HSLA and resistant to corrosion stainless steel material to make.
When chute blockage, canopy coal take place in run coal bin 1; Coal seam thickness reduces on Weighting type belt coal-feeding machine 9 load-transfer devices; Be installed in the cutout of disconnected coal signal transducer 10 perception mediums or rate-of flow on the feeder less than the information of setting value, disconnected coal signal transducer 10 is installed in the discharge nozzle place of belt coal-feeding machine 9.After control box 11 is received chute blockage or disconnected coal signal, actuating motor 7, electrical motor 7 rotations; Drive oil pump 6 work; Oily to oil cylinder 3 delivery pressures through oil pipe 4 through solenoid directional control valve 5, oil cylinder 3 actions drive annular scarfier 2 actions; Drive loose sheet 13 through the pull bar on the annular scarfier 2 and make annular scarfier 2 make the circumference crank motion, play the block clearing effect along the coal bunker inwall.
