Abstract
The utility model discloses an abrasion-proof multi-pipe roller slag water-cooler, which comprises a roller with a jacket and a slag inlet pipe, wherein a plurality of cooling pipes are arranged in the roller, and are communicated with the slag inlet pipe; a helical slag guide piece and a slag extraction plate are arranged in each cooling pipe; a cavity is formed between every two adjacent cooling pipes, and is communicated with the jacket of the roller; a protective layer made from an abrasion-proof heat conduction material is arranged in each cooling pipe, and is arranged at the slag inlet end of the cooling pipe; the thickness of each protective layer along the axial direction of the corresponding cooling pipe is 10cm to 30cm. According to the abrasion-proof multi-pipe roller slag water-cooler, the probability that a barrel is abraded and deformed by the impact force of high-temperature slag can be lowered, and the aim of prolonging the service life of equipment is fulfilled.
Description
Technical field
The utility model relates to a kind of boiler bottom slag cooling device, relates in particular to a kind of wear-resisting multitube water-cooled roller slag cooler.
Background technology
The major function of slag cooler is that the high temperature furnace slag dry method that boiler is discharged is cooling fast, at present, conventional slag cooler is rolling-cylinder type slag-cooler, utilizes the circulation of water between two-layer cylinder, the high-temperature material of inner core is carried out to heat exchange, reach and make high temperature furnace slag cooling object rapidly.But this type of slag cooler exists following weak point: 1, heat exchange area is little, be all that to utilize water circulation in chuck to carry out heat exchange cooling, and utilize area to be less than 1/3 of inner core area during real work; 2, heat radiation is slow, and material concentrates on inner core bottom, with the rotation of cylinder, slowly moves, and only has very little area directly to contact with inner core, and bank lamination is too thick, is unfavorable for the Quick diffusing of heat; 3, tapping temperature is higher, and the tapping temperature of part slag, up to 380 ℃ of left and right, is not easy to transportation and the storage of slag.
In order to address the above problem, following patented technology has been proposed in prior art:
As China Patent No. " 200520030908.3 " discloses a kind of drum type multi-pipe sieving slag cooler, its open day is on November 08th, 2006, its technical scheme is that described drum type multi-pipe sieving slag cooler comprises chilling roll, drives actuating unit that chilling roll rotates, is arranged on the inner core that is mounted with helical blade in its in chilling roll, and the inner core being arranged in chilling roll is at least two.But take the prior art that this patent document is representative, in actual use, because slag has certain impulsive force when entering cylindrical shell by feed end, this just causes the feed end of cylindrical shell easily to wear and tear, and the temperature of slag is very high, add that the impulsive force of slag makes the feed end of cylindrical shell easily be out of shape; After cylindrical shell abrasion deformation, need to change whole cylindrical shell simultaneously, not only cause maintenance cost and production cost to increase, also cause shorten the service life of slag cooler.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of wear-resisting multitube water-cooled roller slag cooler is provided, the utility model can improve slag cooler cylindrical shell in the wearability of feed end, reduces the wear rate of cylindrical shell, thereby reaches the extension device object in service life.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of wear-resisting multitube water-cooled roller slag cooler; comprise cylinder and slag feed pipe with chuck; in cylinder, be provided with many cooling tubes; many cooling tubes are all communicated with slag feed pipe; in every cooling tube, be provided with spiral and lead slag sheet and slag extracting plate; between cooling tube and cooling tube, form cavity; cavity communicates with the chuck of cylinder; it is characterized in that: in described cooling tube, be provided with the protective layer of being made by wear-resisting Heat Conduction Material; described protective layer is arranged on the slag input end of cooling tube, and protective layer is 10-30cm along the axial length of cooling tube.
The thickness of described protective layer is 1-5mm.
Employing the utility model has the advantage of:
One, the utility model is provided with at the slag input end of cooling tube the protective layer of being made by the material of wear-resisting and good heat conductivity, therefore the wearability of protective layer can prevent that high temperature furnace slag from causing cylindrical shell abrasion deformation because of impulsive force, the thermal conductivity of protective layer makes cooling water cooled slag fast, has greatly extended the service life of slag cooler; And protective layer is set to 10-30cm along the axial length of cooling tube, increasing under the prerequisite of less cost, just can significantly reduce the abrasiveness of cooling tube, correspondingly reduced the maintenance cost of equipment.
Two, in the utility model; if the thickness of described protective layer is less than 1mm; the impulsive force that protective layer can bear is less; the slag input end of cooling tube is easy abrasion deformation still; and the thickness of described protective layer is greater than 5mm, will affect the cooling effect of cooling water to slag again, therefore the thickness of described protective layer is 1-5mm; can either protect preferably cooling tube indeformable, guarantee again the cooling effect of cooling water to slag.

Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1, cylinder, 2, chuck, 3, slag feed pipe, 4, cooling tube, 5, protective layer.
