Mechanical equipment of clarifiers

Mechanical equipment of clarifier is supplied for complete set mechanized clarifier of ammonia-tar water of volume 210, 380, 650 m3.

Mechanized clarifier is designed for separation liquid mixture of water, tar and heavy coal-tar products, which are supplied from gas collecting mains of coke oven batteries, and mechanized removal of heavy coal-tar products (foots).

Mechanical equipment of clarifier consists of drive, scraper conveyor, slide gate, reverse device and lever controller.

Equipment is intended for operation in open air in the conditions of aggressive medium of coke-making production. Equipment is used in clarifiers of rectangular and round shapes.

Mechanism of slimesettlers cleaning

Mechanism is designed for mechanized intake of slime from settler of quenching towers and its transportation to the place of discharging.

Mechanism, represented by jib crane, swiveling (or nonswiveling) grab crane on railway travel with rope-block drive of traveling from pulling winch, is proposed. Jib with rope-block drive of traveling accessory (for intake, lifting and discharging of slime) is installed on slewing platform (or on the frame of mechanism directly). Mechanism has two traveling bogies, horizontal and vertical balancers, and also mechanisms for weight lifting, closing of dipper and swiveling. All drives of mechanisms are electromechanical. Remote control of mechanisms is also provided.

Compact plain-sleeve filter

The filter is designed for collection of dust from gas medium, supplied for cleaning after technological apparatus. It is applied in aspiration systems of industry with nonadhesive components of dust.

Sleeve filter consists of body, hopper, screw conveyor, slide gate, blow-off fan, regeneration carriage, gap bridge, plain filtering elements.

The filter operates in the following manner: cleaned gas under action of negative pressure, originated by smoke exhauster of aspiration unit, is supplied into the body, to chamber of precleaning, where partial dedust from great particles of dust is performed due to sharp reduction of gas flow speed. Great dust is settled into hopper and outputted from it by screw conveyor to dust removal system.

Previously dedusted gas distributed uniformly on plain-filter element. Gas is dedusted completely when it transfers through filter material. Then the gas is supplied to chamber of cleaned gas through open ends of plain filter element. After that the cleaned gas is sucked by exhauster and dropped to the atmosphere. Hydraulic resisting of filter rises while accumulating of dust on outer surface of plain filter element. Filter material of plain filter element shall be regenerated by cleaning.

This can be done by the following way: Blowing carriage is moved along gap bridge and time to time stopped on each vertical row of plain filter element. Air, pressurized by blow-off fan which create three air impulses for the period of regeneration of one row, is supplied to blow element of carriage through slide gate and flexible hose; and then it is fed through outlet-nozzle into opened ends of plain filter element. Herewith in the vertical row of plain filter element the blowing air counter-flow is generated against gas to be cleaned and dust, which has settled on outer surface of filter material, is to be shaken off to hopper.

Design of carriage is executed in such a way, that at regeneration not only the row of plain filter element to be cleaned is covered but adjacent rows. It provides dust being shaken-off from regenerated row of plain filter element is settled into the hopper but not onto adjacent filter elements. After completion of regeneration of one row blowing carriage moves to another row.

Description of work:

Coal to be grinded is continuously supplied through chute. Coil is grinded by means of breaking with hammer impacts of rotating rotor and kicking on dash plates. Complete grinding of coil is performed on grate grass. Grinded coil spills through gaps of grate grass partially, and basic mass is dropped through opening on butt of sections of grate grass or through open window of swiveling plate. The grinder can operate at rotor rotation in any direction, so that it extends the service life of fast wearing parts.

Reversing hammer grinder. Working electronic model.

Moveable mixers

Movable mixer -350 is designed for transportation of liquid iron, having the maximum temperature of ° from blast furnaces to steel foundry. It provides the transportation under the minimum heat losses and refining of heat and chemical homogeneity of liquid iron.

Movable mixer consists of body (reservoir), swivel platforms, traveling bogies and the body swiveling mechanism. Body rests on supports executed as a balancers and thrust rollers. Both swiveling platforms are rested on balancers of traveling bogies using spherical bearings. Traveling bogies are equipped with automatic couplers and breking equipment. Design of traveling part of the mixer provides uniform distribution of pressure from each wheel pair. The mixer has required apparatus and two button stations for providing of body swivel in manual mode. The mixer is equipped with system of weighing with possibility of information transfer through radio channel at its filling at blast-furnace plant.
