Description
(1) technical field
The utility model relates to drum process slag treatment unit screw feeding device.
(2) background technology
Drum process slag treatment unit is the slag treatment facility that is used for handling liquid converter slag, and its feeding unit is one to be lined with the chute of anti-material, can only be applicable to the slag of delivery temperature greater than 1200 ℃ of molten, good fluidity; The slag poor for flowability, that viscosity is high then is difficult to deliver into the technology cylindrical shell.And because the popularization and the enforcement of slag splashing technology, the amount of molten slag is fewer and feweri, and the high viscosity slag is then more and more, thereby has restricted the application of drum apparatus.Chinese patent 99211520.5 discloses a kind of " drum process is handled the feeding unit of converter slag ", it comprises the conveyer trough and the high pressure water jet pipe of inclination, the end of going into of conveyer trough has loading hopper, rotary high-pressure spraying pipe is arranged in the funnel, there is the residue chute in the funnel outside, the spiral conveyor rod of arranging along the slag throughput direction is arranged in the conveyer trough, and there is the high-pressure spraying pipe top of conveyer trough along its length direction.Though that the device in this patent can play is continuous, the purpose of unimpeded charging, because the rotating cylinder of spiral is a fixed, therefore, have only rotating band rotor blade to rotate by mandrel.In addition, the end that screw shaft stretches in the cylinder need be fixed, and therefore, complex structure is damaged by the processing medium in the cylinder easily; Need transmission rig, cost is higher.And the end cap that above-mentioned two kinds of feeding manners all require to be attached thereto the cylinder that connects must be fixed, therefore, and the fixedly end cap serious wear of cylinder.
(3) summary of the invention
The purpose of this utility model is to provide a kind of drum process slag treatment unit screw feeding device, the form of the worm conveyor that it rotates simultaneously by blade and cylindrical shell realizes the conveying of high viscosity slag, and the end cap that makes cylinder be connected with feeding unit is rotatable, reduce the wearing and tearing of roller end cover greatly, simple in structure, cost is low.
The utility model is achieved in that a kind of drum process slag treatment unit screw feeding device, comprise loading hopper, the spiral rotating cylinder, mandrel, slag gathering hopper, swivel joint, water-supply pipe and rising pipe, loading hopper is connected with the fixed slag gathering hopper, spiral rotating cylinder around horizontal rotational shaft is housed in the slag gathering hopper, the rotation rotating cylinder is made up of inner barrel and outer cylinder body, be welded with blade on the inner barrel, on the inner barrel axis mandrel is housed, have water entry and water exit in the mandrel, water entry is connected with blade interior passageway one end, water exit is connected with the blade interior passageway the other end, inner barrel is connected with rotatable cylinder by bolt with outer cylinder body one end, the other end of swing roller is connected with swivel joint through mandrel, and rotatable outer cylinder body is connected through sealing member with the shell of fixed filler neck and slag gathering hopper.
Above-mentioned drum process slag treatment unit screw feeding device, described slag gathering hopper are semicircle, and slag gathering hopper is made up of fixed outer hull and inner liner plate.
The form of the worm conveyor that the utility model employing blade and cylindrical shell rotate simultaneously realizes the conveying of high viscosity slag, and the end cap that cylinder is connected with feeding unit is also rotatable, greatly reduces the wearing and tearing of roller end cover like this; Because there is cooling system spiral rotating cylinder inside, thus the life-span of spiral rotating cylinder also be improved, and whole apparatus structure is simple, cost is low.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model drum process slag treatment unit screw feeding device structural representation;
Fig. 2 is a spiral barrel configuration synoptic diagram.
Among the figure: 1 loading hopper, 11 filler necks, 2 spiral rotating cylinders, 20 mandrels, water entry in 21 blades, 22 mandrels, water exit in 23 mandrels, 24 sealing members, the inner core of 25 spiral rotating cylinders, the urceolus of 26 spiral rotating cylinders, 27 joint bolts, 3 swivel joints, 4 semicircle slag gathering hoppers, 41 slag gathering hopper interior lining panels, 42 slag gathering hopper body skiies, 5 water-supply pipes, 6 rising pipes, 7 cylinders.
