It is roller ball mill formula granulating device that domestic slag adopts the method for mechanical granulation, and this device is that slag cooling, curing, ball mill crushing are become the granulation slag.This device is made up of feeding unit and driving arrangement and cylinder, and is furnished with dreg removing system, supply and drain water system and steam-dump system.Its shortcoming is that the granularity of slag is big, and about 0~120mm, granularity is inhomogeneous, and power consumption is big, and equipment heaviness, huge is though but solved the pollution that the slag pollution has produced noise.
Technology contents
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of steel-smelting clinker treatment facility, i.e. steel-making cinder granulation device.
In order to reach above-mentioned purpose, the utility model provides a kind of steel-making cinder granulation device, is to realize like this.
Because slag is compared with blast furnace slag; have than great, basicity is big, flowability is poor, temperature is high, the grain slag granularity is little and slag tap characteristics on an equal basis of mode; therefore the blast furnace slag treatment system of prior art is done bigger improvement, could adapt to the requirement of slag granulation.Steel-making cinder granulation device comprises: slag chute; pelletizer; nozzle; water trap; blowdown stack; the liquid level settling tank; strength lifting device; the granulation water circulating pump; adhesive tape conveyor is formed; slag chute links to each other with pelletizer; pelletizer is connected with water trap; strength lifting device is positioned at the liquid level settling tank; conveyor drive is positioned at the water trap below; it is characterized in that; it also comprises slag ladle and tipple; tipple has controls the activity system of tumbling; slag ladle is sat and is placed on the tipple; after the liquid level settling tank, set gradually intermediate pool; low-pressure pump; spraying cooling pond and water circulating pump, residue is crossed pan and is placed intermediate pool.
Described steel-making cinder granulation device, slag chute are packaged type, and it is convenient to change;
The working face shape of a plurality of liner plates of the granulation wheel in the described steel-making cinder granulation device, its pelletizer is the convex face, and a plurality of liner plates are made by the rare earth alloy steel casting, and manufacturing the medial arc projection increases wear-resisting thickness;
Described steel-making cinder granulation device, its pelletizer water coolant adopts ceramic nozzle, and conserve water, friction durability are long;
Described steel-making cinder granulation device, intermediate pool is established residue and is crossed pan, and the mistake pan can be designed to square, and base plate is a filter screen structure to be opened/closed;
Described steel-making cinder granulation device, its spraying cooling pond is provided with spray equipment.
The utility model compared with prior art has the following advantages:
(1) matched compactness, flow process is short, and floor space is little;
(2) less investment, working cost are low, and the pelletizer liner plate is designed to the convex arc shape, increase the wear-resisting thickness in liner plate middle part, reduce running cost;
(3) device security is reliable, and is simple to operate, easy to maintenance, the operating efficiency height;
(4) epigranular of processing back grain slag, less than 3.5mm, stable performance can directly utilize;
(5) the Fe content that reclaims in the steel scrap can reach more than 80%, and comprehensive benefit is obvious;
(6) environmental pollution is little.

Specific embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described.
Steel-making cinder granulation device comprises: slag chute; pelletizer; nozzle; water trap; blowdown stack; the liquid level settling tank; strength lifting device; the granulation water circulating pump; adhesive tape conveyor is formed; slag chute links to each other with pelletizer; pelletizer is connected with water trap; strength lifting device is positioned at the liquid level settling tank; conveyor drive is positioned at the water trap below; it is characterized in that; it also comprises slag ladle and tipple; tipple has controls the activity system of tumbling; slag ladle is sat and is placed on the tipple; after the liquid level settling tank, set gradually intermediate pool; low-pressure pump; spraying cooling pond and water circulating pump, residue is crossed pan and is placed intermediate pool.
Steel-smelting clinker flows into slag ladle; be transported to by straddle carrier and have the tumble tipple of activity system of control; crane hangs steel slag tank on the tipple, starts the tipple tilting system, and slag ladle is slowly tumbled; slag is flow to movably in the slag chute equably; slag is in slag chute flows into pelletizer, and slag is smashed by the mechanical granulation of high speed rotating wheel liner plate, and the high pressure water that sprays through ceramic nozzle cools off grain slag; slag-water slurry enters water trap, further cooling.The water trap rotary drum rotates, and grain slag carries out slag, water sepn through screen cloth.The screen cloth of the dehydrated device of slag takes the receiving opening that is left to conveyor on the deflector chute to, is transported to transfer point through conveyor, carries out scum separation, slag outward transport or reprocessing and utilizes.
Water after the water trap grain slag separates overflows back in the intermediate pool by the liquid level detritus pool, and the residue in the liquid level settling tank is mentioned by strength lifting device and sent water trap back to.In middle pond, the quadrate residue is crossed pan and can be filtered the residue of recirculated water once more and stay residue and cross in the pan, and recirculated water is got to the spraying cooling pond through low-pressure pump, recycles with water circulating pump after the spraying cooling device cools.Because the ratio of slag is great, the granularity of slag is little, and the screen cloth of the dehydrated device of grain slag leaks down to be flushed in the liquid level settling tank by water and precipitates, and strength lifting device is put on slag and transported outward, and water returns in the liquid level sediment.
Steel-making cinder granulation device, the working face shape of eight liner plates of granulation wheel is the convex face, is made by the rare earth alloy steel casting, and its water coolant adopts ceramic nozzle, and conserve water, friction durability are long;
The utility model patent, technology is simple, easy and simple to handle, floor space is little, processing power is big, installed capacity is low, water consumption is low, investment is little, environmental pollution is little, improve labour intensity and condition, the reliable slag safe, after handling of equipment can effectively utilize.
