Description
Technical field
The utility model relates to the power plant and stores the material bin delivery system, is specially a kind of floating type run coal bin anti-block apparatus.
Background technology
At industry feeding systems, particularly coal-fired power plant's coaling system such as electric power, coal, chemical industry, because China's ature of coal composition variation is bigger, particularly in rainy season, run coal bin ubiquity blockage problem.Stop up in case coal takes place, coal mill will no-load run, and generator set will be forced to urgent the reduction exerts oneself, and more serious meeting causes boiler extinguishment, the unplanned stoppage in transit of unit.Run coal bin stops up, and not only causes very big energy dissipation, and has a strong impact on the safe operation of unit.Its plugging reason: 1, the obstruction that causes of run coal bin structure: run coal bin mostly is cement, steel, the box-like structure of cement steel reinforced concrete, and its planform is basic identical, and is namely suitable for reading big, following young.The lock gate hatch entrance of existing run coal bin end opening mostly is diameter 600mm or 630mm, and sectional area has only 0.3 sq m.During operation, material falls by deadweight from top to bottom.The material that falls is owing to flow in conical vessel, so more flow downward, area is littler, and material itself is just formed extruding, and friction coefficient increases rapidly behind the attached wall of material, and attached wall material can comparatively fast increase, and more the more thick formation of collection is stopped up; Top chute blockage is owing to the bottom obstruction causes.After the bottom was stopped up, storage capacity seriously diminished, and stops up more serious.2, the obstruction that causes of material: namely contain a certain amount of clay, ancudite, quartz, feldspar iron pyrite etc. in the composition of coal, they constitute coal-fired ash content.Wherein clay can absorb aqueous dispersion and becomes colloidal particle in the pasty state, has cohesiveness, usually causes fire coal to cohere obstruction when content is higher.Also have because of coal-fired aqueous ingredients: clay mineral has only dispersions of just can expanding behind the water of absorption in the coal, produces cohesive action and causes coal handling system to stop up, the coal supply interruption.Therefore, the granularity of coal is more little, and water injectivity is just more strong, is more easily cohered agglomerating formation by clay and stops up.The existing method of stopping up of handling, except manually knocking the mediation, known preventing plug dredging equipment is divided into following several, a kind of is the mode of vibration mediation, both vibrating motor directly is installed on the run coal bin shell, when finding that run coal bin stops up, the Vibration on Start-up motor, because run coal bin is the rigidity structure, cause that amplitude reduces, weak effect, noise greatly, particularly easily the run coal bin basis is shattered, with the material in the storehouse shake more real, stop up more very.Another kind is the mediation mode, exactly a kind of hydraulic linear sports equipment is contained in the storehouse, and when run coal bin stopped up, dredging machine up-and-down movement mediation was stopped up, and the problem of existence is mediation weak effect, equipment complexity, easily causes new obstruction.Also have a kind of rotary wall type anti-clogging material warehouse device, namely the material bin device is made up of three parts, and the upper and lower part is divided into static storehouse, and centre portion is revolution wall type material bin, built-in broken arch block clearing device (scraper).In the motion process of anti-blocking system, material near the inner barn wall can't and bulkhead between form stable arch, the basis of obstruction is disintegrated, and stops up also just can not take place again.Its weak point is complex structure, and the cost height easily causes the rotating mechanism overload when buying securities with all one's capital operation, influence the equipment operation.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned run coal bin delivery system, and a kind of have anti-blocking, mediation and wear-resisting functions are provided, and can thoroughly solve a kind of floating type run coal bin anti-block apparatus of the blockage problem of run coal bin.
The utility model be purpose by the following technical programs: a kind of floating type run coal bin anti-block apparatus, comprise feeding mouth, broach hopper and discharging opening, feeding mouth one end is provided with flange, flange is connected with the run coal bin upper end, the feeding mouth outside is connected with the support upper end feeding mouth arm of force, the support lower end discharging opening arm of force is connected with discharging opening, on at least four supports, the lower end is connected by tie bolt with a material mouthful arm of force, broach hopper is installed in the support, the suitable for reading of broach hopper is tightly connected by sealing suitable for reading and feeding port, sealing suitable for reading contacts with the feeding mouth arm of force around the outside, the end opening of broach hopper is tightly connected with discharging opening by the end opening sealing, the end opening sealing outside contacts with the discharging opening arm of force, discharging opening is provided with flange, flange is connected with lock gate hatch flange on the feeder, described broach hopper middle part outside fixed installation vibration excitor pedestal, on the vibration excitor pedestal vibration excitor is installed, mounting shock absorber bottom base on the hard-wired bumper top base in the broach hopper bottom discharging opening arm of force corresponding with the bumper top base, mounting shock absorber between bumper top base and the bumper bottom base.The vibration excitor pedestal of vibration excitor is symmetrically welded at the middle part of broach hopper.Vibration excitor is vibrating motor.Shock absorber is metal spring, and last seal and lower seal mouth are that rubber seal is made.The broach hopper back cut diameter is 1 meter-2 meters, and optimum diameter is 1.55 meters.
Advantage of the present utility model is: with the run coal bin bottom, it is upwards 3 meters 1.5 meters of the diameter left and right sides segmentation of run coal bin lock gate hatch, top still is former design shape, the floating type broach hopper of steel storehouse section is made in the bottom, broach hopper storehouse section is not directly to be connected with the run coal bin on top and the lock gate hatch of bottom, but connect by soft sealing structure, the bottom arranges the damping supporting mechanism, and the steel broach hopper becomes buoyancy body.Install vibration excitor in this floating type broach hopper storehouse section, during the vibration excitor operation, clean out the thing that sticks on the taper warehouse that floats.Floating type broach hopper maximum load is 10kn, and highly design is between 2 meters to 3 meters, and back cut diameter designs between 1 meter to 2 meters, about 1.5 meters of best back cut diameters.Frequency limit is generally 600-1450Hz.Maximum displacement is ± 3-5mm.The about 100g. of peak acceleration.When the utility model moves, material passes through in the run coal bin anti-block apparatus, having thin sticking raw material constantly sticks on the oscillating plate and constantly thickening, behind certain hour, exciting source is connected power supply and is vibrated, and vibratory force passes through support, reach on the floating type broach hopper, floating type broach hopper vibration comes off the material that sticks on the floating type broach hopper, reaches the purpose that prevents from stopping up or stopping up the back mediation.
