Description
Technical field
The utility model relates to a kind of spreading disk, and what be specifically related to is a kind of spreading disk structure of powder concentrator.
Background technology
Powder concentrator is an important composition equipment of closed cycle grinding system.Its effect is: selected by the qualified fine powder of grinding to certain particle size in time, meal returns to and carries out grinding again, prevents the fine powder cushioning effect that mistake grinding and adhesion abrasive body cause in mill, and improves the mill efficiency of grinding machine; Finished product granularmetric composition can be regulated, prevent thickness uneven, ensure end product quality.
Spreading disk be powder concentrator dispersion and follow-up screening fine powder time a vitals, after powder falls into spreading disk, outwards shed with certain angle by spreading disk, make powder obtain evenly, fully disperseing in separating chamber, thus create conditions for realizing efficient separation.
But, existing spreading disk due to structural design unreasonable, its ubiquity is caused a larger defect, that is: fed by powder concentrator top when going out to grind cement, and fall on spreading disk by after dispersion and impelling, although define the material curtain of uniformly continous, the powder condensed due to electrostatic effect group is difficult to be spread out completely; Meanwhile, due to air-flow upwards can be produced when spreading disk rotates, therefore, the air-flow that powder also can be easy to along with rising moves upward, and thus, just significantly reduces the follow-up efficiency selecting powder.
Utility model content
The purpose of this utility model is the spreading disk structure providing a kind of powder concentrator, mainly solves existing spreading disk and there is the inefficient problem of powder lot dispersing.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A spreading disk structure for powder concentrator, comprises the spreading disk main body with fan-shaped Turbogrid plates, and is arranged on the spreading district of this spreading disk bottom part body, also comprises blocking material ring and auxiliary blade; Described blocking material ring is evenly arranged around the fan-shaped Turbogrid plates of spreading disk main body for one week; Card 200 ~ the 300mm of the distance from bottom spreading disk main body of described blocking material ring, distance spreading disk body top edge 120 ~ 150mm, and the length of blocking material ring is 200 ~ 300mm; Described auxiliary blade is evenly arranged around spreading disk body top edge for one week.
As preferably, the card 300mm of the distance from bottom spreading disk main body of described blocking material ring, distance spreading disk body top edge 150mm, and the length of blocking material ring is 300mm.
Compared with prior art, the utility model has following beneficial effect:
The utility model is reasonable in design, simple operation, it by increasing the blocking material ring of auxiliary blade and suitable length in spreading disk main body, and define the setting position of the two, and blocking material ring and the distance between card and edge, thus when spreading disk works, can material be made well evenly to let go, effectively improve grinding efficiency and return more than dressing sieve, also reduce Hui Fenliang simultaneously, reduce the circulating load of powder concentrator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name that Reference numeral is corresponding is called:
1-spreading disk main body, 2-blocking material ring, 3-spreading district.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the utility model provides a kind of spreading disk of novel powder concentrator, and it comprises spreading disk main body 1, blocking material ring 2, spreading district 3 and auxiliary blade (accompanying drawing does not draw).Described spreading disk main body 1 has fan-shaped flase floor, described blocking material ring 2 is evenly arranged around this fan-shaped flase floor for one week, and blocking material ring 2 is respectively 200 ~ 300mm and 120 ~ 150mm apart from the card of spreading disk main body and top edge, meanwhile, the length of single blocking material ring 2 is 200 ~ 300mm; Described spreading district 3 is arranged on the bottom of spreading disk main body 1; Described auxiliary blade is then evenly arranged around spreading disk main body 1 top edge for one week.
The utility model is arranged at the inside of powder concentrator, its main operation principle is: start powder concentrator, spreading disk main body 1 starts High Rotation Speed, fed by powder concentrator top when going out to grind cement, fall after spreading disk main body 1 is disperseed, the power impelling of being centrifuged is gone out, and the powder group impact of condensing due to electrostatic effect, on blocking material ring 2, thus can produce powerful impulsive force and make powder roll into a ball dispersion; Meanwhile, a part of dispersed powder group also can be rebounded by blocking material ring 2 (producing refraction), is collided, thus again disperseed by powerful impulsive force with follow-up by spreading disk main body 1 impelling material out.In order to strengthen the dispersion effect of powder group further, in the present embodiment, blocking material ring 2 is preferably 300mm and 150mm respectively apart from the card of spreading disk main body and top edge, and the length of single blocking material ring 2 is preferably 300mm.
In the process that spreading disk main body 1 rotates, it can produce air-flow upwards, now, because auxiliary blade also rotates with spreading disk main body 1, thus can produce downward air-flow.Downward air-flow is greater than air-flow upwards, and therefore after being offset by air-flow upwards, make spreading disk main body 1 create the downward air-flow in direction, now, under airflow function, dispersed powder can enter into the spreading district 3 bottom spreading disk main body 1; Simultaneously fallen thick powder group continues to drop in spreading disk main body 1, and is again centrifuged power high-speed projectile and goes out, and so repeatedly carries out, and makes electrostatic effect and the powder group of condensing is easy to just be disperseed, thus also improves the efficiency of dispersion.
The utility model is after the existing spreading disk structure of improvement, through test, the grinding efficiency of powder concentrator has brought up to 74% by original 52%, cement grinding system all-in one desk produces and has brought up to 83t/h by 67t/h, go out to grind cement specific surface area qualification rate and risen to 96.8% by 75.8%, and also eliminate cement grinding mill grinding phenomenon and full mill, paste mill phenomenon.Therefore, compared to existing technology, the utility model has substantial feature and progress.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
