The utility model relates to a powder fluidization component device, which is characterized by comprising a blowing ring arranged at the circumference of a conical body of a coal dust storage hopper, wherein the blowing ring is provided with an air inlet and at least three air outlets radially and uniformly distributed; the coal dust storage hopper below the blowing ring is circumferentially provided with filters which correspond to the air outlets and are in the same number as the air outlets; each filter comprises a steel pipe which is obliquely and downwards arranged on the coal dust storage hopper; one end of the steel pipe is inserted into the coal dust storage hopper; a double-end slipknot pipe is inserted in the steel pipe ad is fixed together with the steel pipe through a steel pipe flange and a steel flange cover plate; the end of the double-end slipknot pipe inserted into the coal dust storage hopper is connected with a filtering cloth bag, while the other end is connected with a compressed air inlet pipe through the steel pipe flange and the steel flange cover plate; and the other end of the compressed air inlet pipe is connected with the air outlets of the blowing ring. The powder fluidization component device can effectively solve the problem of the unsmooth flowing of coal dust caused by wall collision, mouse holes or caking in the coal dust storage hopper and can be widely applied to powder storage and supply systems for coal dust boilers or the other powder storage and supply systems.
Description
Technical field
The utility model relates to a kind of fluidization components device, particularly about a kind of powder fluidization components device that is applicable to the coal dust warehouse.
Background technology
At present, in industrial pulverized-coal fired boiler, the general coal dust warehouse that adopts, problems such as wall built-up, rat hole or conglomeration appear in coal dust easily in its storehouse, thereby cause the defeated coal of system not smooth or inhomogeneous, and can make when serious to form the thick-layer wall built-up in the coal dust warehouse, cause the coal dust humidity, thereby cause breakdown of equipment, make the steam generator system cisco unity malfunction.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of powder fluidization components device that is applicable to the coal dust warehouse.
For achieving the above object, the utility model is taked following technical scheme: a kind of powder fluidization components device, it is characterized in that: it comprises that one is arranged on the winding-up ring on the cone circumference of coal dust warehouse, and described winding-up ring has radially well-distributed air extractor duct of an admission port and at least three; Circumferentially be provided with fil corresponding with described air extractor duct position and that quantity is identical on the described coal dust warehouse of described winding-up ring below; Described fil comprises that one is the steel pipe that tiltedly is arranged on down on the described coal dust warehouse, and an end of described steel pipe inserts in the described coal dust warehouse; Be inserted with a pair of head slip-knot pipe in the described steel pipe, described double end slip-knot pipe is fixed together by a steel pipe flanges and a steel flanges cover plate and described steel pipe; The end that described double end slip-knot pipe inserts in the described coal dust warehouse connects a filtration cloth bag, and the other end is connected a compressed air inlet pipe by described steel pipe flanges with the steel flanges cover plate; The other end of described compressed air inlet pipe is connected with air extractor duct on the described winding-up ring.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model coal dust warehouse is provided with winding-up ring and fil, the coal dust warehouse is jetted, cause the coal dust not smooth problem that flows thereby can effectively solve owing to occur wall built-up, rat hole or conglomeration in the coal dust warehouse.2, the utility model has installed the filtration cloth bag additional at the fil end, can prevent that impurity from entering in the coal dust warehouse.The utility model design is unique, and compact conformation is easy and simple to handle, can be widely used in pulverized-coal fired boiler storage powder-supply system or other storage powder-supply system.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises that one is arranged on the winding-up ring 2 on the cone circumference of coal dust warehouse 1, and winding-up ring 2 has radially well-distributed air extractor duct 3 of an admission port (not shown) and four (only as example, being not limited to this).Circumferentially be provided with fil 4 corresponding with air extractor duct 3 positions and that quantity is identical on the coal dust warehouse 1 of winding-up ring 2 belows.
As shown in Figure 2, fil 4 comprises that one is the steel pipe 5 that tiltedly is arranged on down on the coal dust warehouse 1, and an end of steel pipe 5 inserts in the coal dust warehouse 1.Be inserted with a pair of head slip-knot pipe 6 in the steel pipe 5, double end slip-knot pipe 6 is fixed together with steel pipe 5 by a steel pipe flanges 7 and a steel flanges cover plate 8.The end that double end slip-knot pipe 6 inserts in the coal dust warehouse 1 connects a filtration cloth bag 9, and the other end is connected a compressed air inlet pipe (not shown) by steel pipe flanges 7 with steel flanges cover plate 8.The other end of compressed air inlet pipe is connected with the air extractor duct 3 of winding-up ring 2.
The quantity of the utility model fluidization components device can decide according to actual conditions, and is arranged on the cone circumference of coal dust warehouse 1 differing heights.Present embodiment respectively is provided with one group of fluidization components (as shown in Figure 1) on the circumference of the cone upper and lower of coal dust warehouse 1.
In the foregoing description, the steel pipe 5 of fil 4 plays the effect of fixing and support and airtight whole fil 4, steel pipe flanges 7 plays the effect that is connected compressed air inlet pipe and double end slip-knot pipe 6 with steel flanges cover plate 8, and filtration cloth bag 9 plays and prevents that impurity from entering the effect of coal dust warehouse 1.
The utility model at first is connected the compressed air line in the steam generator system in use with the admission port that winding-up encircles on 2, after treating to fall into coal in the coal dust warehouse 1, pressurized air enters winding-up ring 2.Pressurized air enters in the double end slip-knot pipe 6 of fil 4 by air extractor duct 3 and connected compressed air inlet pipe on the winding-up ring 2.Under air pressure, double end slip-knot pipe 6 compressed airs are after cloth bag 9 filters after filtration, to jetting in the coal dust warehouse 1.Under the winding-up effect of pressure air, the coal in the coal dust warehouse 1 is fallen smoothly by the outlet of coal dust warehouse 1 cone bottom, thereby can not produce wall built-up, problem that rat hole or conglomeration etc. hinder the coal blanking.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
