Abstract
A roller device of cold slag deslagger comprises a rotary roller (2) driven by a drive mechanism (3), a water channel (8) inside the deslagger and a slag channel (9) surrounded by cooling water, and the slag channel comprises an inner hump-shaped non-conventional type pipe arranged vertically along the roller and the inner hump (12) is part of the pipe wall and is distributed in the radial direction along the pipe. Thanks to the inner hump-shaped non-conventional type pipe slag channel used in the utility model, the heat conducting area of the roller is not only increased, but also slag is favorable to roll, with the advantages of more effective cooling slag effect, simple manufacturing process and low cost for the product.
Description
The utility model relates to the cold slag that is used for CFBB, the parts of residue extraction mechanism, is a kind of drum apparatus of cold-slag slagging equipment.
In recent years, thermal efficiency height, coal adaptability are wide because it has for CFBB, flue gas can low-temp desulfurization etc. advantage, therefore, be widely used in China.But, the cold slag supporting, residue extraction mechanism with it also research, the exploitation among, still immature.The revolving cylinder of cold-slag slagging equipment particularly, it is the heart of equipment, its version directly influences cooling effect and the continuity of deslagging and the efficient of slagging tap of slag.CN2262171Y disclosed " cold-slag slagging equipment " is provided with polygon pipe formula slag passage in its revolving cylinder, the pipe inwall also is provided with floor.The slag passage of this structure though conduction has certain benefit because the increase meeting of floor is to heat, still exists following shortcoming: 1, the width of floor be subjected to the restriction of inwall should not be excessive, little, the cold slag weak effect of heat transfer area; 2, floor is easy to wear, the life-span is short; 3, manufacturing process complexity, weld seam are many, the product cost height.
The purpose of this utility model is to overcome the deficiencies in the prior art, the drum apparatus of a kind of cold slag, slag-discharging device is provided, hump shape shape tube structure in its slag passage adopts, not only increased heat-conducting area, and the slag charge that can roll well, make it to have higher cold slag effect and the advantage that manufacturing process is simple, product cost is low.
The utility model is realized by following technical measures.A kind of drum apparatus of cold-slag slagging equipment, comprise by driving mechanism transmission, rack-mounted revolving cylinder, be provided with aquaporin in it and slag passage that the water that is cooled surrounds, be positioned at cylinder top and slag channel connection slag feeding chamber, be positioned at cylinder bottom and the slag removing chamber of slag channel connection, the water inlet pipe that is communicated with aquaporin and outlet pipe.Described slag passage is made up of a kind of interior hump shape shape tube that vertically is provided with along cylinder, and in other words, interior hump shape shape tube is at tube wall upper edge pipe inwardly protruded hump to be set vertically.Hump is the part of tube wall promptly, is radial protrusion on the pipe cross section.The quantity of interior hump is no less than 3.The shape of cross section of interior hump comprises: circular arc, U-shaped, V-arrangement, rectangle, trapezoidal etc.
Described aquaporin is the cooling water cavity that surrounds described slag passage and be communicated with water inlet pipe, outlet pipe.
Interior hump shape shape tube is provided with quantity in cylinder decides according to the quantity of slag that goes out of slag-discharging device.Generally be no less than 6.
The utility model compared with prior art has the following advantages:
1, cold slag is effective.Because hump shape shape tube structure in the slag passage adopts, the polygon pipe that it and same cross-sectional are amassed are relatively, heat transfer area obviously increases, and the cooling water capacity that surrounds shape tube obviously increases, and therefore, cold slag effect will improve naturally greatly.The interior hump of shape tube is identical with the inner rib plate effect of polygon pipe, all be to establish in order to stir slag, but the former is abundant, latter's width is subjected to the restriction of heating condition can not broad, otherwise easy burn-out, therefore, promote slag, fully the former is better than the latter aspect rolling, and is more conducive to the cooling of slag.
2, manufacturing process is easy.Interior hump shape shape tube can adopt the technology manufacturing of assembly welding again behind the segmentation die forming, and is much easier than rib welding plate in the polygon pipe, and weld seam is few.Not only low cost of manufacture, and system easy to control the quality.
3, long service life.Because hump is stocky than floor, hump top slyness not only is beneficial to slag and passes through, and significantly reduces wearing and tearing in addition, has prolonged the service life of equipment, particularly takes under the situation of forward and backward operation at equipment, and the utility model is more apparent, and it is superior.
Below by embodiment, be further described in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation of cold-slag slagging equipment;
Fig. 2 is the A-A profile of Fig. 1, i.e. the drum apparatus cross-sectional structure schematic diagram of " slag-discharging device ";
Fig. 3 is the B-B profile of Fig. 2.
As shown in Figure 1, 2, 3, the drum apparatus of a kind of cold slag, slag-discharging device, comprise: be installed in revolving cylinder 2 on the frame 5 by driving mechanism 3 transmissions, be provided with water channel 8 in it and the slag passage 9 of the water encirclement that is cooled, be positioned at the slag feeding chamber 6 of cylinder top and slag channel connection, be positioned at the slag removing chamber 7 of cylinder bottom and slag channel connection, the water inlet pipe 10 that is communicated with aquaporin, outlet pipe 11.Its slag passage 9 is made up of 18 interior hump shape shape tubes that vertically are provided with along cylinder 2, and hump 12 is parts of tube wall in it, is radial protrusion on the cross section of pipe.The quantity of interior hump 12 is 6.Its water channel 8 is the cooling water cavity that surrounds interior hump shape shape tube and be communicated with water inlet pipe 10, outlet pipe 11.The cross section of interior hump be shaped as U-shaped, also can do forming V-shape, rectangle, trapezoidal, circular arc or other shapes.
The course of work of the present utility model is as follows:
High temperature furnace slag enters slag feeding chamber 6 from slag inlet 1, flow into slag passage 9, revolving cylinder 2 is ceaselessly done gyration, and slag is upper and lower falling in the slag road, the effect of hump 12 within adding, driving slag rolls up and down, heat of slags is fully conducted, and slag does not stop rotation with cylinder, promptly tumbles the bottom from the top of cylinder and enters slag removing chamber 7, fall on the conveying equipment by slag notch 4 at last and transport, realized continuous discharging slag.
