Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into The scope of this utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, in this utility model embodiment, open a kind of wear prevention chute, including chute bottom plate 1 With chute cover, also including that interior lining panel 2, interior lining panel 2 are fixedly connected on chute bottom plate 1 inner surface, interior lining panel 2 upper surface is some flat The groove 12 of row arrangement, is provided with the abrasion-proof stick 9 adapted with groove shapes in groove 12.

This utility model simple in construction, on the basis of existing technology, will add one layer of interior lining panel in chute bottom plate, then will Interior lining panel has done further improvement, and some abrasion-proof sticks are arranged on the design in groove, forms some cambered surface protective layers, makes material not Can contact chute bottom plate even interior lining panel, thus effectively prevent from directly wearing and tearing because of material chute bottom plate and interior lining panel and change whole Individual chute, can realize the efficient utilization of chute by directly changing abrasion-proof stick.

Chute bottom plate 1 bottom is provided with lower baffle plate 6, and abrasion-proof stick 9 lower end embeds in lower baffle plate 6, abrasion-proof stick 9 top and groove 12 for being welded to connect.

Being provided with some bolts hole 7 on groove 12 and chute bottom plate 1, chute bottom plate 1 passes through bolt hole 7 with interior lining panel 2, Recycling nut 10 and bolt 11 connect.

Preferably scheme, groove 12 is semi-circular recesses, and abrasion-proof stick 9 is solid pole.

And the diameter of abrasion-proof stick 9 is not more than the diameter of groove 12, a diameter of 35-45mm of abrasion-proof stick 9, groove 12 is a diameter of 38-46mm, as abrasion-proof stick 9 diameter 28mm, and changes abrasion-proof stick 9.

Wherein chute cover is mutually permanently connected by n side guard and forms, wherein n 2, chute cover left and right sides end respectively with Chute bottom plate 1 left and right sides end is welded to connect, and chute cover is provided with water inlet pipe 8.

Preferably scheme, chute cover includes the first side guard the 3, second side guard 4 and the 3rd side guard 5；Chute cover includes First side guard the 3, second side guard the 4, the 3rd side guard 5 and the 4th side guard 14；Chute cover is arc-shaped cover 13.

In material, chute bottom plate 1, interior lining panel 2 are made for rustless steel, when material is by chute, in chute bottom plate The abrasion of region, portion is serious, and lower region includes that lower baffle plate 6 is denuded relatively fewer, but existence is denuded therefore lower baffle plate 6 material and elected height as Intensity Wear-Resistant Compound Steel Plate, model has KN-55, KN-60, KN-63 etc., has the features such as hardness is high, solderable.

At present, in water-coal-slurry preparation process, chute plays an important role.The process of wet method controlling the water circulation coal slurry is: will screening Good coal is through belt transmission, then is transported in rod mill be ground slurrying through entering coal chute.Main grinding in rod mill body Medium is rod iron, and rod iron has enough rigidity and hardness, in use can keep straight and not bend, after abrasion Abrasion-proof stick still has the strongest rigidity and hardness after taking off, and wearability is the strongest.But, in prior art, rod mill grinds and makes Used abrasion-proof stick, the most all discards, and wastes resource.

Abrasion-proof stick in this utility model embodiment one uses the discarded rod iron of rod mill.

Embodiment one:

As shown in Figures 1 to 8, chute cover includes the first side guard the 3, second side guard 4 and the 3rd side guard 5, wherein, resistance to Frotton uses rod mill with discarded rod iron, when being ground to a diameter of 35-45mm because of the abrasion-proof stick in rod mill, is easily generated unrest Rod, disconnected rod phenomenon, need to take out from rod mill, and therefore, in scheme, abrasion-proof stick diameter great majority are 35-45mm, and its material is 65Mn/60Mn, and, abrasion-proof stick 9 top and groove 12, for being welded to connect, chute cover are provided with water inlet pipe 8, water inlet pipe 8 Effect guides current to enter chute, and on the one hand, water is the composition that wet method prepares that water-coal-slurry must be added to, the opposing party in the effect of water Face, when entering coal wear prevention chute and entering coal, prevents coal grain from blocking chute by current；Abrasion-proof stick 9 lower end embeds in lower baffle plate 6, When abrasion-proof stick 9 is entered coal particle abrasion to a diameter of 25mm, just change abrasion-proof stick 9.

Abrasion-proof stick in the present embodiment uses the discarded rod iron of rod mill, makes rod mill grind used discarded rod iron It is utilized effectively, reaches the purpose of twice laid, it is to avoid the wasting of resources.

Embodiment two:

This utility model chute cover is mutually permanently connected by n side guard and forms, wherein n 2, the present embodiment chute cover bag Include the first side guard the 3, second side guard the 4, the 3rd side guard 5 and the 4th side guard 14, be i.e. n be 4, as shown in Figure 9.

The shape design of the present embodiment chute cover, when inventory is big, it is possible to ensure that material runs through.

Embodiment three:

As shown in Figure 10, in the present embodiment, chute cover is arc-shaped cover 13.

In sum, the abrasion-proof stick in embodiment one uses the discarded rod iron of rod mill, makes rod mill grind and used Discarded rod iron be utilized effectively, reach the purpose of twice laid, it is to avoid the wasting of resources.

In this utility model embodiment, some abrasion-proof sticks are arranged in groove, form some cambered surface protective layers, make material not Can contact chute bottom plate even interior lining panel, thus effectively prevent from directly wearing and tearing because of material chute bottom plate and interior lining panel and change whole Individual chute, can realize the efficient utilization of chute by directly changing abrasion-proof stick；It is prevented from chute by wear down, worn out, it is to avoid Chute leakage coal, the problem leaked, make whole chute extend service life, save business equipment cost, it is to avoid change chute and make The shut-down become and maintenance, it is to avoid the labor intensity of employee and risk factor, decrease enterprise's production cost, creates warp for enterprise Ji benefit；
