According to the utility model, compared with the prior art, the powder concentrator has the characteristics of reasonable design, simple structure, good using effect and the like, abrasion of the cases of a draught fan and a turbine can be reduced, and the service life of the powder concentrator can be prolonged.
Description
Technical field
The utility model relates to cement manufacture plant field, specifically a kind of powder concentrator that reduces impeller and casing wearing and tearing.
Background technology
Raw material grinding mill powder concentrator after producing, find because of circulating fan band material too much, draught fan impeller and casing serious wear, every 20 days will soldering once, use at most 7,8 months, after the scheme of having formulated impeller surface and paste wear-resistant ceramics is implemented, because of raw material grinding mill, to keep away peak time many, wear-resistant ceramic frequent expansion, contraction, different because of the coefficient of expansion of pottery and metal again, use not long-time, surface ceramic just comes off in succession, does not reach theoretical effect.So not only reduced service life, also to staff, brought trouble.Spreading disk is that powder concentrator internal main is wanted distribution device, it is responsible for must shedding at the inner active position of powder concentrator material is even, but due to the impact that controlled by fineness and specific area, sometimes may need the rotating speed of adjusting powder concentrator main shaft to control fineness and specific area, when the speed of mainshaft reduces, material is shed less than desirable position because centrifugal force is little.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and the powder concentrator of a kind of reasonable in design, minimizing impeller that result of use is good and casing wearing and tearing is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of powder concentrator that reduces impeller and casing wearing and tearing, comprise pulverized-coal collector and spreading disk, upper surface at spreading disk is provided with several isolation strip iron, isolation strip iron is arranged evenly successively around the bulk cargo dish center of circle, at grade, the size of every isolation strip iron is identical at the outer rim place of the outer end of isolation strip iron and spreading disk; The inner core bottom of pulverized-coal collector is provided with deepens at the bucket end, and lower open mouth on inner core, is connected with inner core lower end at the bottom of the intensification bucket of open topped, and inner core is all identical with external diameter and the internal diameter of deepening the bucket end.When the speed of mainshaft reduces, thereby can improve material centrifugal force by isolation strip iron, can shed desirable position.
Described a kind of powder concentrator that reduces impeller and casing wearing and tearing, described in it, isolation strip iron is arc, and one end, inner side of every isolation strip iron is identical to the distance at spreading disk center, and one end, outside of every isolation strip iron is corresponding with spreading disk outer rim respectively.Preferably arc is crossed by isolation strip Tie Tong, by this, is arranged and material can be shed away uniformly.
Described a kind of powder concentrator that reduces impeller and casing wearing and tearing, described in it, inside the iron of isolation strip, one end is 400-600mm. to the distance at spreading disk center, distance between preferred isolation strip iron and spreading disk center, can better material be kept in to spreading disk centre like this, and then by isolation strip iron, material be separated away uniformly.
Described a kind of powder concentrator that reduces impeller and casing wearing and tearing, its isolation strip iron is provided with 2-8 bar.
Preferably the number of isolation strip iron, according to the concrete condition in use procedure, take six as best results.
Isolation strip iron is directly welded on bulk cargo dish, and welding process is comparatively simple, and operation is got up also comparatively stable like this.
Compared with prior art, the beneficial effect producing is the utility model:
The utlity model has the features such as reasonable in design, simple in structure, easy to use, function admirable, practicality, lengthen the length of pulverized-coal collector induced duct, reduce short circuit air quantity, reduce dust concentration; Air circulation fan impeller is able to normal use; The centrifugal force that increases material, can evenly must shed out material, more effectively must control fineness and specific area, has reduced the wearing and tearing of draught fan impeller machine casing, the service life of having improved powder concentrator.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is schematic diagrames of spreading disk AA direction in accompanying drawing 1.
In figure: 1, pulverized-coal collector, 2, inner core, 3, isolation strip iron, 4, spreading disk, 5, deepen at a bucket end.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail below.
As shown in drawings, the powder concentrator of minimizing impeller of the present utility model and casing wearing and tearing, its structure comprises pulverized-coal collector 1 and spreading disk 4, upper surface at spreading disk 4 is provided with six isolation strip iron 3, isolation strip iron 3 is arranged evenly successively around bulk cargo dish 4 centers of circle, and the outer rim place of the outer end of isolation strip iron 3 and spreading disk 4 at grade; Described isolation strip iron 3 is arc, and one end, inner side of every isolation strip iron 3 is identical to the distance at spreading disk 4 centers, and iron 3 one end, inner side in isolation strip are set to 500mm to the distance at spreading disk 4 centers.Between spreading disk 4 axis and isolation strip iron 3, form like this gathering ground of a temporary material, when spreading disk 4 rotates, material just can, uniformly to surrounding diffusion, enter respectively in the space between isolation strip iron 3.
According to the experiment effect of field operation, at this, isolation strip iron 3 is provided with to six, the size of every isolation strip iron 3 is identical.When main shaft rotates, rotating speed does not need the impact that controlled by fineness and specific area thus, can be increased the centrifugal force of material by isolation strip iron 3, more effectively must control fineness and specific area, and material is accurately dished out.
Inner core 2 bottoms of pulverized-coal collector 1 are provided with deepens at the bucket end 5, lower open mouth on inner core 2, and at the bottom of the intensification bucket of open topped, 5 are connected with inner core 2 lower ends, and inner core 2 is all identical with external diameter and the internal diameter of deepening the bucket end 5,
Deepening bucket end pulverized-coal collector inner core can make with same mould, so just forms an integral body, equals and pulverized-coal collector inner core is lengthened to 180mm.Through using checking: dust content reduces 90%, and air circulation fan impeller is able to normal use.The intensification bucket end 5, is identical with the material of the inner core of pulverized-coal collector 1.
Except the technical characterictic described in description, be those skilled in the art's known technology.
