Abstract

The utility model relates to a combined type wearproof alloy pipe. The utility model is especially suitable for the discharge hopper, the feed hopper and the material conveying angle pipe of a power plant, a mine and a building material industry. The utility model adopts a technical proposal that wearproof materials are fixed on the body of the utility model. The utility model improves the abradability of the feed hopper and the discharge hopper, and the service life of the utility model is extended; compared with an original pipe, the service life of the utility model can be extended by more than 5 times.

Description

Combined abrasion resistance alloy pipe

The utility model relates to the defeated material bend pipe used on a kind of abrasion resistance alloy pipe, particularly power plant, mine, the building material industry and into and out of hopper.

The tubular equipment that known industrial and mineral uses all is to adopt 25# carbon plate or manganese plate, forms with welding or bonding mode manufacturing, and its shortcoming is very easily to come off and wear out, and abrasion resistance is low, and working life is extremely short, and replacing frequently.In order to increase the method that abrasion resistance adopts more increases steel plate thickness, consequently weight increases, and has strengthened mechanical load, and has fallen flat.

The purpose of this utility model provides a kind of abrasion resistance height, the combined abrasion resistance alloy pipe of long service life.

The technological scheme that realizes the utility model purpose is: be fixed with high-abrasive material on body.

Above-mentioned high-abrasive material is fixed with the steel plate that is welded on the body.

Above-mentioned high-abrasive material can make alloy watt, is fixed on the body with welding or with clamping bolt.

Above-mentioned high-abrasive material only is fixed on the position easy to wear of body.

The utility model is compared with prior art and has been improved abrasion resistance, has prolonged working life, compares with former pipe, and can prolong more than 5 times its working life.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the fixing structural representation of high-abrasive material on the concentrated wear position of bend pipe;

Fig. 3 is A-A ' sectional view among Fig. 2;

Fig. 4 is the apparatus for feeding outline drawing;

Fig. 5 is B-B ' sectional view among Fig. 4.

The utility model is described in further detail below in conjunction with the structure drawings and Examples:

As shown in Figure 1, on body 3, be fixed with high-abrasive material 2, the fixation method of high-abrasive material 2 is that steel plate 1 is welded on the body 3, is welded into mezzanine space between steel plate 1 and the body 3, pours into this mezzanine space after with the method for casting wear resistant alloy material being melted and forms wearing layer; High-abrasive material 2 also can be an alloy watts 7, is fixed on the body 3 with the method for welding or bolton, and high-abrasive material can be rich chromium cast iron, alloyed steel.High-abrasive material also can only be fixed on the position easy to wear of body 3, and this abrading section can be the outer wall of body 3, also can be inwall.

Embodiment 1:

As Fig. 2, shown in Figure 3, the utility model is used in the schematic representation on the defeated coal bend pipe of power plant, on the outer wall at the position easy to wear of bent tubular body 3, welding steel 1 pours into the wear resistant alloy material 2 of fusing in the mezzanine space between steel plate 1 and the body 3, when coal when arrow 4 directions enter bend pipe at a high speed in figure, on the outer wall of bend pipe, formed worn area, in the worn area, after body 3 is worn through, the wearing and tearing of bearing raw material by wear resistant alloy material 2, thereby the life-span of greatly having improved bend pipe.

Embodiment 2:

As Fig. 4, shown in Figure 5, the utility model is used in the schematic representation on power plant's apparatus for feeding, this equipment is made up of supply pipe 5 and feeding funnel 6, feeding funnel 6 is welded into the feeding funnel housing with mezzanine space by steel plate 1, in mezzanine space, pour into the wear resistant alloy material 2 of fusing, thereby improved the wear-resisting property of feeding funnel 6; On the position easy to wear of supply pipe 5, it is the bottom of tube wall, with welding or with bolton alloy watts 7 is arranged, the alloy watt above-mentioned high-abrasive material of 7 employings, shape according to pipe, cast the alloy watts 7 of some, assembly unit is fixed on the inwall of supply pipe 5 Lower Halves, to increase the wear-resisting property of supply pipe 5.
