The corrugated filter screen has long service life, simple installation and detection, and good filtration effect.
Description
Technical field
The present invention relates to a kind of screen pack, be applied to the Handling Blast Furnace Granulated Slag system.
Background technology
Domestic most of blast furnace adopts rotary water slag filter device (or claiming rotary drum grain slag separator), and screen pack all is installed on rotating cylinder.
As Fig. 1, Fig. 2, shown in Figure 3, rotary water slag filter device is made up of transmission device 1, feed arrangement 2, rotating cylinder 3, support support roller 4, the husky collection bucket 10 of slag, rubber conveyer 11, outer cover 5, compressed air blowing cleaner 6, the cleaning device 7 of purifying waste water etc.; The outer wall of rotating cylinder 3 is equipped with outer net 8, and the inside of rotating cylinder is equipped with blade net 9, and the two ends of rotating cylinder are supported on the support roller 4 at four by rail supported, drives rotating cylinder 3 rotations by transmission device 1; Grain slag mixture when blast furnace is produced enters rotating cylinder 3 from feed arrangement 2, and water leaches through rotating cylinder; Slag sand picks up top to rotating cylinder through blade net 9 under the turning effort of rotating cylinder, and drops to the husky collection bucket 10 of slag, transports through rubber conveyer 11.
At present, what the screen pack that grain slag separates mainly adopted is the structural shape of " grid+fine-structure mesh ", and the screen pack of this structure is the two-layer structure, and skin is a grid, plays a supportive role, and internal layer is the steel wire fine-structure mesh, filtration.The structure of " grid+fine-structure mesh " has two drawbacks in actual production: 1. the steel wire of internal layer fine-structure mesh is short service life; 2. the two-layer structure causes maintenance to change inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of corrugated filter screen, this corrugated filter screen has long service life, the characteristics easily of overhauling is installed.
To achieve these goals, technical scheme of the present invention is: corrugated filter screen is characterized in that it comprises housing, filter screen, termination shrouding; Filter screen becomes the gauffer type, and end welds with housing respectively about filter screen; The front and back end of filter screen is welded with the termination shrouding respectively, the welding of termination shrouding and housing, and the frame endoporus on the housing is positioned at the space that filter screen, termination shrouding are surrounded; Filter screen is provided with filter opening, and filter opening communicates with frame endoporus on the housing; Have elongated hole on the shrouding of termination, elongated hole communicates with frame endoporus on the housing; Housing is provided with and installs and fixes the hole.
The invention has the beneficial effects as follows:
1, filter screen adopts the roll forming of punching steel plate, a laminar structure, and long service life is installed maintenance conveniently;
2, the gauffer of filter screen has increased filter area greatly, has improved filter effect;
3, the termination shrouding of filter screen is also gone out elongated hole, can effectively increase total filter area.

The specific embodiment
As Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, corrugated filter screen, it comprises housing 12, strengthens gusset 13, filter screen 14, termination shrouding 15; 14 one-tenth gauffer types of filter screen (adopt the punching steel plate to be rolled into the gauffer type, or claim undaform), (the right of Fig. 4 is a right-hand member to end, and the left side is a left end with housing 12 welding respectively about filter screen 14; Being the rear end in the paper, is front end towards the onlooker), weld with housing 12 respectively the bottom surface, the lowest point of the front and back end of filter screen 14; The front and back end of filter screen 14 is welded with termination shrouding 15 respectively, and termination shrouding 15 and housing 12 welding, the frame endoporus 18 on the housing 12 are positioned at the space that filter screen 14, termination shrouding 15 are surrounded; Filter screen 14 is provided with filter opening 17, and filter opening 17 communicates with frame endoporus 18 on the housing 12; Have elongated hole 19 (go out elongated hole on the termination shrouding 15, play the aided filter effect) on the termination shrouding 15, elongated hole 19 communicates with frame endoporus 18 on the housing 12; Housing 12 is provided with and installs and fixes hole 16.
Described gauffer type is a sinusoidal pattern.Be welded with above the place, the lowest point of described filter screen 14 and strengthen gusset 13, strengthen the front and back end of gusset 13 and weld with housing 12 respectively.
Use: corrugated filter screen replaces existing outer net 8, is installed in the outer wall of rotating cylinder.
