Description
The present invention is the relevant mould brush mould dust suction of annotating steel mill and using (or ingot mould clean with water and dust suction) field.
Ingot mould will adhere to some foreign matters unavoidably on the inwall of ingot mould after pouring into a mould steel ingot, these foreign matters such as untimely being disposed will be caused serious ingot surface defect next time when annotating ingot.Expect the steel ingot of high-quality, wish that ingot mould will clean before use fully, and the residual steel and the residue that are retained in the mould behind each ingot casting are disposed.
But, domestic in the ingot mould scale removal process, main rely on artificial or some extremely plain instruments carry out, thereby labour intensity is high.This mainly is because pending ingot mould also has the cause of very high surface temperature.
Abroad, be described in detail the device that utilizes the injection steel grit to clear up mould among day disclosure special permission 55-90268.The mould that it is adapted to cast, it is too high to be applied in the cleaning work of ingot mould cost.
2 have introduced a kind of scavenging machine that utilizes rotary-chain to clean ingot mould among the day disclosure special permission 59-13943, though take another step, also have a lot of disadvantages, such as operating efficiency are low, and chain damages easily, and the cleaning effect of across corner is poor.
A kind of cleaning equipment of forming by the brush of many separation of inventing out among the BP GB2089698.This cleaning equipment has overcome above two kinds shortcoming, but but can't dispose the foreign matter at the bottom of die orifice and the mould.
The present invention, solved the problem that above invention exists in cleaning ingot mould foreign matter, provide can be in the extremely short time ingot mold, inwall mould at the bottom of slag, residual steel and other adhesions of adhesion clean very neatly and a kind of mould notes that exhausts are used and brushed the steel vacuum cleaner.
Brush mould vacuum cleaner of the present invention is made up of the special-purpose crane of truss-like door type, brush suction device, orientation adjustment and concentric device, hoisting mechanism, dust delivering tube road, deduster, dust storehouse, atmospheric control.
Wherein the special-purpose crane part of truss-like door type is hung basic identical with general door type.Brush suction device comprise blowing device the slidingtype blower cover, inhale chew, steel wire brush and control appliance thereof form.Respectively to the cleaning of die orifice refuse, dust: to cleaning with water of mould inwall; Cleaning to mould inner bottom part refuse and dust.
Be cleaning die orifice place dust, refuse, establishing one in the outside of brush suction device can utilize the high velocity air that slot produced of the certain distance that forms between blower cover bottom margin and die orifice that dust, refuse inspiration suction are chewed at the square blower cover of telescoping tube outer wall slip.Flow velocity slows down but the resistance that flowing gas produced in coaxial plane is with the increase of radius.Like this four jiaos of places of die orifice wind speed is slowed down relatively.Then dust, refuse are difficult for being sucked away.Establish an air loop duct for addressing this problem in the flaring bottom, at the Si Jiaochu of airduct nozzle is housed, utilize the nozzle jet-stream wind with the die orifice dust, refuse blows afloat the back and is brought into to inhale and chew.High-pressure blast is supplied with blower cover bottom bellows chamber by the air compressor that is located at above the crane carriage by the high pressure rubber hauling pipe.This bellows chamber and winding-up pipe are communicated with by electronic guiding valve, and the switching of electronic guiding valve is finished by limit switch control time delayer.
To cleaning with water of die wall attachment is to utilize four groups of steel wire brushes, by diagonal, is separately fixed on each slide block, and slide block is flexible in the slideway helical pitch.It 6 starts the power pneumatically and promotes air-cylinder piston and finish.When the steel wire brush was cleaned with water the mould inwall, brush came the control air cylinder internal pressure to die wall effect normal pressure by regulating choke valve.The helical pitch of slide block in slideway promptly is the cosine value that the mould ruling grade multiply by 45.
The cleaning of mould bottom refuse, dust is to be inhaled to chew by a square disc shape to finish.The shape that bottom shape is similar to the mould inner bottom part is chewed in suction so that inhale chew and mould at the bottom of between the slit under negative pressure, forms the high speed uniform air flow, the refuse of chewing the bottom in the square disc shape suction can be sucked away in instantaneous time.The top that suction is chewed adopts clamp to connect with the telescoping tube lower end.Chew above the square plate owing to the steel wire brush arrangement is installed in to inhale, and, become consumable accessory, and for the purpose of the convenience in consideration maintenance and the use, adopt the detachable suction of the multiple model that is suitable for up big and down small size to chew owing to the operating rate of equipment is very high.Suction chew and mould at the bottom of between the slit chew the bottom by suction and adjust that screw rod reaches, inhale the time of staying of chewing at the bottom of mould and control the synchronous limit switch chain lock in time relay delayer and the lifting device by time-delay relay.
Orientation adjusting device and concentric device comprise: fixed jacket pipe and sealing and fixing three groups on the outer tube with movable pulley, worm reduction gear, two pull pin and be fixed on dial on the telescoping tube, braked wheel, brake, motor with and connector, the airtight and watertight padding of stationary pipes section form.It act as adjusts the brush suction device flat orientation, makes it aim at the die orifice position, reaches the brush die device mould inwall is evenly cleaned with water.Brush suction device and dial are fixed on the telescoping tube, telescoping tube is unsettled to be connected by bearing with balancing disk, and move driver chuck on the telescoping tube by being installed in symmetrical double-pin on the worm reduction gear on the fixed jacket pipe, make the telescoping tube in unsettled drive brush suction device left and right sides position rotating, thereby reach the orientation adjustment of the corresponding die orifice of brush suction device.For guaranteeing that two fingers do not bump against with the reductor casing, establish left and right sides limit switch control motor braking at bottom half.Concentric for guaranteeing telescoping tube and stationary pipes and the reductor axle center inner chamber that is fixed on the outer tube, and protect with the sealing of the airtight and watertight padding of telescoping tube junction, sealed close with movable pulley three groups of fixed jacket Guan Shangshe.For the wearing and tearing that reduce airtight and watertight padding and the resistance that airtight and watertight padding increases when reducing rotation, telescoping tube adopts the Surface Machining part in telescopic section.
Hoisting mechanism is made up of gravity disk, movable pulley, equalizer pulley, steel wire rope, reel, reductor, motor and dual brake.Its effect is to drag the brush suction device that is connected on the telescoping tube by the assembly pulley on the gravity disk, the brush of ingot mould is inhaled handled.Gravity disk is fixed on the telescoping tube by rolling bearing and gland thereof.Two groups of movable pulleys are separately fixed at the gravity disk both sides, and steel wire loop is contained on the equalizer pulley.Again through being fixed on the reel behind two groups of movable pulleys on the gravity disk.It promotes power by motor, and the gravity by gravity disk and brush suction device of descending overcomes in the brush suction device that is installed on the telescoping tube bristle to the frictional resistance between die wall, to reach cleaning with water die wall.The required gravity theory value that descends is: brush the die wall normal pressure be multiply by coefficient of friction and the normal pressure and the mould gradient sine value long-pending and.But when prototype test, find to differ too big with this theoretical value, think by analysis: the brush suction device when brush suction device is adjusted the die orifice coordinate on the telescoping tube and the concentricity of die orifice are not enough, the deviation of supposing concentricity is at 20 millimeters, not having distortion at telescoping tube is under the situation in the elasticity allowed band, normal pressure between brush and die wall will increase several times power, and then the resistance of each sliding part also increases relatively.In order to overcome the unavoidable error that occurs in this operation, decline gravity is got 2.5～3 times of its theoretical value.
The dust delivering tube road is made up of telescoping tube, fixed jacket pipe, connecting tube, exhaust duct and volume damper, stop valve.Its effect is: form the pipeline of connect by various pipe fittings and valve plate and deduster, blower fan, dust in the mould is delivered to the deduster tip, and is intercepted purification by filtrate; Purify back gas through blower fan to efflux row of conduits big to gas; Wherein in exhaust duct, establish a control valve and under normal duty, work, and before the blower fan import, establish a stop valve to adjust motor, during work with the blower fan connection; Valve plate is closed in the work alternation procedure, the empty load of motor operation.
The lower end of telescoping tube is connected with brush suction device, and the epimere sealing is inserted in the stationary pipes.Brush suction device is cleaned distance with water in mould be the flexible distance of telescoping tube epimere in the fixed jacket pipe promptly.The effective triangle gusset of fixed jacket is fixed on the plane of crane carriage, and the lower end is fixed on the basis of reductor casing in the orientation adjustment mechanism that is connected with it and motor (this basis and electric panel room, operating room skeleton consubstantiality).The upper end after telescoping tube promotes and the upper surface flange face of fixed jacket pipe leave the buffering surplus, in order to avoid telescoping tube is clipped in the reducing place of fixed jacket pipe upper surface flange when promoting.
The clean end points of the dirt of pipeline promptly be remove sit device advance the air draft contact.Therefore point is in the baseplane of crane carriage, and be subjected to that a type hangs walk crosswise track girder apart from 3.1 meters home records tolerance systems, adopt two reverse square pipes, and pass through the crane carriage body and be connected with pipeline.In operation, brush is less than a type suction time and hangs traveling and crane carriage to the adjustment time of mould coordinate, so establish a stop valve at the fans entrance place, controls swing reservoir by electromagnetic air valve and carries out, and valve is a normally closed type.
