Abstract
The utility model relates to a feeding device for a slag treating device, which is used for the pretreatment for steel slag with bad flowability and high viscosity, and a large block of tank bottom slag. The utility model comprises a wide port chute and a roller outlet, wherein, a crushing device is fixedly connected with the inner part of the chute. The lower part of the chute is provided with a plate type conveyer which is communicated with the roller outlet, a nozzle which sprays water to lead the chain plate to be cooled is arranged below the chain plate of the plate type conveyer, and a chain plate cover shell is arranged on the outside of the chain plate. A feeding device which adopts the structure can effectively preliminarily crush various big blocks of metallurgical slag, and safely convey the metallurgical slag to a next processing unit to achieve the purpose that slag does not fall down on the ground, processing is carried out in the hot state, and operation environment is improved. Finished product slag which is processed by the utility model has uniform granules, stable performances, and direct use without ageing.
Description
Technical field
The utility model relates to a kind of metallurgical slag feeding unit, relates in particular to a kind of feeding unit of slag treatment unit.
Background technology
With respect to traditional metallurgical slag treatment technology, drum process slag treatment unit has flow process weak point, less investment; Safe and reliable, energy consumption is low; Advantages such as the slag after the processing can directly utilize, environment friendliness progressively obtain insider's approval and high praise.Its technological process is: the liquid slag that converter produces is poured slag ladle (bag) earlier into, be transported to the slag treatment plant by the cinder ladle chassis then, by driving the liquid slag of good fluidity in the jar (bag) is poured in the cylinder charging chute, by handling in the chute importing cylinder, this charging chute is a traditional wide-mouth chute.Because the cause of rebasing slag in the slag splashing of converter and the slag ladle, what deliver to the slag treatment plant mostly is slag and the big blocky jar of end slag that flowability is very poor, viscosity is very big, these slags or being bonded in the charging chute walls does not go up and down, integral body is blocked chute mouth and is advanced not go, and the use range of cylinder is very limited.Therefore, viscosity slag big, mobile difference have to be handled with traditional technology, or falls in the dried slag field on cylinder next door, handles after forklift seethes cooling again, has both wasted the energy, causes great environmental pollution again.
Summary of the invention
The purpose of this utility model provides a kind of drum process slag processing feeding unit, and the jar end slag precrushing of flowability is very poor, that viscosity is very big slag and bulk is advanced in the cylinder with the apron conveyor smooth delivery of power again.
The utility model relies on the jar end slag fragmentation of the surging force of crisp rigid, the gravity of jar end slag and breaker roll with bulk, and dry slag and clinker is sent in the wide-mouth chute with the rotation of breaker roll and crushing teeth in batches.Because the even rotation of carrier bar and water spray, cooling can be avoided the bonding of slag and the local superheating of carrier bar, and then send the slag that gets off evenly to change in the cylinder on top.
Structure of the present utility model comprises a wide-mouth chute and a drum outlet, an affixed shredder assembly in this chute, and be provided with a transfer roller in its underpart, communicate with drum outlet.
Described shredder assembly comprises at least one group of crushing teeth, and this crushing teeth is fixed on the breaker roll, and by a drive mechanism.
One hydrologic cycle cooling system is arranged in breaker roll and the crushing teeth.
In described wide-mouth chute, also be provided with at least one grate bar, be fixed on this wide-mouth chute inwall.
Described grate bar is to be supported by the back up pad that is fixed on the wide-mouth chute inwall, and both ends are pressed with two block pressur plates.
The sidewall inclination angle of described wide-mouth chute is 60 °～80 °.
Described transfer roller is an apron conveyor, comprises a drive unit, two great wheels, guide rail and the carrier bar that covers on guide rail and the great wheel.
The carrier bar of described apron conveyor has carrier bar water spray refrigerative nozzle.
The carrier bar of described transfer roller is provided with a carrier bar case outward.
The inclination angle of described drag conveyer is 10 °～30 °.
The feeding unit that adopts this structure is the metallurgical slag of the various bulks of precrushing (comprise jar at the bottom of slag) effectively, and safe transport is to next processing unit, reaches that slag does not land, thermal state disposing, the purpose of operating environment improved.Finished product slag after this device is handled also possesses epigranular (the 0.3-10mm proportion is greater than 80%), stable performance (free calcium oxide content is less than 4wt%), the advantage that does not need ageing just can directly utilize.
Description of drawings
Fig. 1 is the diagrammatic cross-section of the utility model feeding unit.
Fig. 2 is a vertical view of the present utility model.
Embodiment
Referring to Fig. 1, a group or array crushing teeth 1 links to each other with breaker roll 12 by welding or riveted joint or other connection, place in the wide-mouth chute 2, and under the drive of driving mechanism 11, uniform rotation, and rotating speed is adjustable.In breaker roll 12 and the crushing teeth 1 circulating water cooling system is arranged, every group of crushing teeth has at least two teeth.Grate bar 14 is evenly distributed on the import of wide-mouth chute 2, on the inwall of the wide-mouth chute 2 that two ends are fixed on, this fixed form can adopt by the back up pad 4 that is fixed on wide-mouth chute 2 inwalls and support, both ends are pressed with two block pressur plates 3, this pressing plate 3 is fixedlyed connected with back up pad 4, thereby grate bar 14 is fixed on the inwall of wide-mouth chute 2, makes the grate bar 14 that at high temperature damages to change rapidly, do not influence normally carrying out of slag process for producing.Wide-mouth chute upper and lower opening is all bigger, and sidewall weak point and inclination angle are in 60 °～80 ° scopes, and be non-caked on sidewall to guarantee slag.
Wide-mouth chute 2 belows are connected to an apron conveyor, comprise 13, two great wheels 6 of a drive unit, guide rail 9 and the carrier bar 8 that covers on guide rail 9 and the great wheel 6.Material enters wide-mouth chute 2, evenly delivers on the bottom carrier bar 8 through crushing teeth 1 fragmentation and through grate bar 14.Drive unit 13 drives great wheel 6, and carrier bar 8 will be accepted material and send into cylinder 10 under the drive of great wheel 6, further be processed into finished product.Nozzle 7 is positioned at the below of carrier bar 8, and to the cooling of spraying water of the carrier bar back side, the water after cooling is used flows in the cylinder 10 the cooling water circulation uses as the cylinder internal structure again.Guide rail 9 is used to support the weight of carrier bar and material.Be covered with carrier bar case 4 in great wheel 6 and carrier bar 8 outsides, whole carrier bar and runner and processed slag charge are surrounded, prevent that slag charge and process steam are excessive, improve environment.
The utility model is an environment protection novel in the metallurgical slag treating processes, has that flow process is short, efficient is high, an operational safety, cost is low, environment is good characteristics.Finished product slag after this device is handled also possesses epigranular (the 0.3-10mm proportion is greater than 80%), stable performance (free calcium oxide content is less than 4wt%), the advantage that does not need ageing just can directly utilize.The utility model is particularly suitable for the metallurgical slag that flowability is poor, viscosity is bigger that produces because of slag splashing.Therefore, the utility model can be applied to domestic and international vast metallurgy industry, particularly steelworks, iron work fully.
