Abstract

The utility model relates to an inverted cone that medium speed ground, including the inverted cone body, inverted cone body outward appearance weld the net that draws of iron, draw and be equipped with wear-resisting dope layer on the net, the net that draws form by the crisscross combination of a plurality of hollow hexagons, wear-resisting dope layer's thickness be 15-25 mm. Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a back taper of intermediate speed mill, has characteristics such as low cost, simple structure, convenient to use, science practicality, has strengthened mill back taper abrasion resistance, has reduced repair welding number of times, has prolonged its life, has improved work efficiency, for the enterprise reduce unnecessary economic loss.

Description

A kind of reverse taper of medium-speed pulverizer

Technical field

The utility model relates to ironmaking equipment technical field, particularly a kind of reverse taper of medium-speed pulverizer.

Background technology

Two powder process belts will add 460 tons of coke powders every day, the quality of coke powder own is hard, enter after grinding machine, with processing after coal dust mix to grinding machine reverse taper form wash away, accelerated wear test, therefore the reverse taper of medium-speed pulverizer monthly needs large area repair welding once, affects the normal coal powder injection of blast furnace.

Summary of the invention

The purpose of this utility model is to provide a kind of reverse taper that increases grinding machine reverse taper service time, extends grinding machine medium-speed pulverizer in service life.

For achieving the above object, the utility model is realized by the following technical solutions:

A reverse taper for medium-speed pulverizer, comprises reverse taper body, and described reverse taper body appearance is welded with drawing in the net of irony, draws in the net to be provided with wear-resistant paint layer.

Described combines by multiple hollow hexagonals are staggered.

The thickness of described wear-resistant paint layer is 15-25mm.

Compared with prior art, the beneficial effects of the utility model are:

A reverse taper for medium-speed pulverizer, has the features such as with low cost, simple in structure, easy to use, science is practical, has strengthened grinding machine reverse taper wear resistence, reduce repair welding number of times, extend its service life, improved operating efficiency, for enterprise reduces unnecessary economic loss.

Accompanying drawing explanation

Fig. 1 is structure chart of the present utility model;

Fig. 2 is the local structural graph of the utility model Fig. 1;

Fig. 3 is the structure chart that the utility model draws in the net.

1-reverse taper body 2-draw in the net, 3-wear-resistant paint layer, 4-separator 5-row coal blower fan, 6-grinding roller

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:

As shown in Figure 1, Figure 2 and Figure 3, the reverse taper of a kind of medium-speed pulverizer of the utility model, comprise reverse taper body 1, what described reverse taper body 1 appearance was welded with irony draws in the net 2, draw in the net 2 to be provided with wear-resistant paint layer 3, described drawing in the net 2 combines by multiple hollow hexagonals are staggered, and the thickness of described wear-resistant paint layer 3 is 15-25mm.

While using the utility model, when coke powder and coal dust fall into after medium speed mill, under the effect of centrifugal force, radially move outwardly, in medium speed mill, form one deck coal bed, coal bed passes through under the medium speed mill can rotate around the axis, coke powder and coal dust are milled into powder between medium speed mill liner plate and grinding roller 6, powder is incorporated into medium speed mill top by row's coal blower fan 5, separate by separator 4, powder forms and impacts the outside of reverse taper body 1 simultaneously, reverse taper body 1 is because surface draws in the net 2 and wear-resistant paint layer 3, effectively prevent the damage of reverse taper body 1.

Above, be only basic principle of the present utility model, not the utility model imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.

Claims

1. a reverse taper for medium-speed pulverizer, comprises reverse taper body, it is characterized in that, described reverse taper body appearance is welded with drawing in the net of irony, draws in the net to be provided with wear-resistant paint layer.

2. a kind of medium-speed pulverizer reverse taper according to claim 1, is characterized in that, described drawing in the net combines by multiple hollow hexagonals are staggered.
