The waste cracking furnace hold down gag
Technical field
The utility model relates to a kind of garbage disposer hold down gag, especially relates to a kind of waste cracking furnace hold down gag.
Background technology
At present, the waste cracking furnace of people's exploitation is equipped with the less of hold down gag, even is not furnished with the rubbish hold down gag, be unfavorable for like this material cracking in the stove, be difficult in the pyrolysis furnace continuously, stably produce gas, even affect the aerogenesis quality, produce a large amount of flue gases, cause environmental pollution.The incinerator that has is equipped with upper dregs removing device, upper dregs removing device be by on push away that the screw rod in the dregs removing device moves down on the slag motor-driven, drive holding pad and move down compression rubbish.But the screw rod of this dregs removing device is installed in the furnace chamber of waste cracking furnace, and the coal tar that the garbage cracking process produces easily gathers, is bonded on the screw rod, causes screw rod to move and has some setbacks, even the present situations such as stuck occur, and the coal tar that remove on the screw rod is very difficult.And sealing property is relatively poor, and the toxic and harmfuls such as flue gas that produce in the refuse burning and cracking process easily leak into outside the pyrolysis furnace, cause the problems such as environmental pollution.
The utility model content
The purpose of this utility model provides a kind of constantly cracking of rubbish that makes in the waste cracking furnace, and is constantly compacted, makes in the stove garbage cracking get more complete, waste cracking furnace hold down gag thoroughly.
For achieving the above object, waste cracking furnace hold down gag of the present utility model comprises the mechanisms such as compression, clamping and water source, it is characterized in that: described hold-down mechanism is to be made of two cover pressurization water vats, protecgulum connecting plate, piston rod connecting plate, bonnet connecting plate.The protecgulum of two cover pressurization water vats is fixed tightly in respectively the two ends of pressure (hydraulic) water cylinder front cover connecting plate by the pull bar of water vat, two bonnet is fixed tightly in respectively on the bonnet connecting plate by pull bar, article two, piston rod is threaded connection and is fixed tightly in respectively piston rod connecting plate two ends, the pressurization water vat forms an integral body, two cylinder body synchronous operations when guaranteeing pressurization by being rigidly connected.The piston rod connecting plate is fixed tightly in by screw on the cover plate of pyrolysis furnace, does not produce movement, and the cylinder body of two pressurization water vats can move up and down.For through hole sealing ring and fairlead are housed in the middle of the pyrolysis furnace cover plate, sealing ring plays sealing function to the gas that produces in the pyrolysis furnace, and fairlead plays guide effect to depression bar.Be through hole in the middle of pressure (hydraulic) water cylinder front cover connecting plate and the bonnet connecting plate, two ends are drilled with pressurization water vat pull bar installing hole, tighten up protecgulum and the bonnet of two pressurization water vats by pull bar.Be through hole in the middle of the piston rod connecting plate, two ends have the piston rod thread hole, are used for tightening up the piston rod of two pressurization water vats.Endoporus is equipped with fairlead in the middle of the bonnet connecting plate, and depression bar passes the intermediate throughholes of bonnet connecting plate, protecgulum connecting plate, piston rod connecting plate, pyrolysis furnace cover plate, and the lower end is fixed tightly on the holding pad.Described clamp mechanism clamps water vat by two and consists of, and upper clamping water vat is fixed tightly on the pressure (hydraulic) water cylinder front cover connecting plate, can move along with pressurization water vat cylinder body.Lower clamping water vat is fixed tightly on the piston rod connecting plate, does not produce movement.Two clamp water vat and are single-acting cylinder, it also can be double acting cylinder, the centre is through hole, depression bar passes its endoporus, clamping water vat can and loosen the depression bar clamping, and under normal circumstances, two clamp water vats and remain a clamping, a relaxation state, and the duty of last time had memory function.
On the basis of the above, the utility model also can be done further perfect, set up a cover water source controlling organization, comprise that a pressurization water vat hand-operated direction valve, two clamp water vat hand-operated direction valve, pressurization water vat pressure regulator valve, clamp the water vat pressure regulator valve, two hydraulic lock, and pipeline etc., two clamp water vat for being connected in parallel, respectively by hand-operated direction valve control water source direction.Two pressurization water vats are also for being connected in parallel, by a hand-operated direction valve control water source direction.Be connected in series separately a hydraulic lock at two water inlet pipe places that clamp water vat, the control mouth of hydraulic lock is connected with the B mouth that clamps the water vat hand-operated direction valve, because the connection characteristics of control loop make two clamping water vats keep one to loosen a clamped condition always, and have memory function, keep last duty.Clamp water vat and two water route branches of pressurization water vat and be connected in series separately the pressure size that a pressure regulator valve is regulated the water source.
When waste cracking furnace is filled rubbish, start the furnace bottom automatic ignition device, lower part rubbish begins cracking, and one, connect the water source, give first upper clamping water vat piston upper chamber input service WATER AS FLOW MEDIUM, upper clamping water vat is in clamped condition, clamps depression bar; Two, because hydraulic lock has memory function, under the original state, the hydraulic lock of lower clamping water vat is in closed condition, during the input service medium, hydraulic lock control mouthful input water, open hydraulic lock, the water that is fixed on the lower clamping water vat piston upper chamber of piston rod connecting plate flows into water tank, and lower clamping water vat is in relaxation state.Three, give two cavity of resorption input service WATER AS FLOW MEDIUM that compress the water vat piston, because the piston rod of pressurization water vat is fixed on the bell motionless by connecting plate, two cylinder bodies move down together, driving depression bar and holding pad moves down together, regulate the size of hydraulic pressure, can guarantee that the rubbish in the waste cracking furnace is in impaction state always.Garbage cracking in stove is complete, stirs the handle commutation of pressurization water vat reversal valve, gives the piston upper chamber input water of two pressurization water vats, the cavity of resorption draining, and two cylinder bodies move up, and drive depression bar and holding pad and move up together.After moving into place, stir first lower clamping water vat hand-operated direction valve, give lower clamping water vat input water, lower clamping water vat clamps.Then stir the handle commutation of clamping water vat hand-operated direction valve, open hydraulic lock to the draining of upper clamping water vat, upper clamping water vat loosens; Four, close the water source, close pressurization water vat pressure regulator valve, because hydraulic lock has locking and memory function, the above water vat that clamps of institute still keeps relaxation state, and lower clamping water vat still keeps clamped condition.The cylinder body of two pressurizations this moment water vat slides downwards together under the effect of deadweight and puts in place.Give again at last the waste cracking furnace load garbage, fill rubbish and repeat again top operation.
The beneficial effects of the utility model are: a kind of constantly cracking of rubbish that makes in the waste cracking furnace is provided, and constantly compacted, make in the stove garbage cracking get more complete, waste cracking furnace hold down gag thoroughly.
This device utilizes water or compressed air as working media, has the characteristics such as nonflammable, clean environment firendly, low price.
