Abstract
The utility model discloses a wear-resistant diffusion pipe for slag discharging, which has an outer tube body. The utility model is characterized in that an inner lining of the outer tube body is provided with a molding corundum sintering tube, and an adhesive layer is arranged between the molding corundum sintering tube and the outer tube body. The utility model has the advantages of good abrasive resistance, smooth and integrated inner wall, simple manufacturing process, high precision, cheap price, long service life which is about 2 to 3 years.
Description
The utility model relates to the parts in the combustion system dreg removing system of thermal power plant, is a kind of injection diffusion transport cinder liquid line.
The scum pipe flow is big, speed fast and cinder has certain degree of hardness owing to carry, so wear intensity is severe especially, this tubing matter of general power plant is cast steel, wear resisting cast iron, high chromium, nickel and nitrogen foundry goods, diabase cast stone, 16Mn, white cast iron, 38Cr20Ni14Si2, high alloy steel etc., but total wear-resisting effect is all not satisfactory.Promptly with 16Mn, high alloy steel material, though than before material, its wear-resisting property increases, as does not do repairing, must be worn through in 8 months at most, serious promptly had mill to leak phenomenon in 2-4 month to take place, need often keep in repair, influence operation.Country's " 95 " key popularized project, " 863 " high-tech product: the C-T ceramic composite steel pipe, adopt centrifuge method production, though wear-resisting property is preferably arranged, but its defective is also a lot, as being composited in straight tube, the surface is more coarse, and the fusion residue is arranged.
The purpose of this utility model provides that a kind of wear-resisting property, inner wall smooth, technology are simple, low price, high-time wear-resisting deslagging diffusing tube.
Technical solution of the present utility model is: a kind of wear-resisting deslagging diffusing tube, have outer tube body, and the difference of itself and prior art is: at the outer tube body liner moulding corundum sintered pipes is arranged, between moulding corundum sintered pipes and outer tube body sticker layer is arranged.
Corundum sintered pipes described in the utility model is conical or square, rectangular, hopper shape, elbow-shaped.Certainly, also can adopt other suitable shape and structures.
Moulding corundum sintered pipes described in the utility model is consistent with the outer tube body inner wall shape.Certainly, also can adopt other suitable construction forms.
Tackiness agent described in the utility model adopts modified epoxy or silica gel.Certainly, also can adopt other suitable bonding.
The utility model has the advantages that: wear resistance is good, and is high temperature resistant, inner wall smooth is complete, precision is high, low price, and the spreadable life limit for length is about 2-3, and easy for installation, and is in light weight, can reduce material consumption, worker's consumption effectively, save cost, increases economic efficiency.Compare with the C-T ceramic composite steel pipe, solved the difficult problem that can not produce Taper Pipe, special pipe, technology is simple, need not centrifugal smelting process, and no fusion residue.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of a kind of wear-resisting deslagging diffusing tube of the present utility model.
Fig. 2 is the structural representation of the wear-resisting deslagging diffusing tube of another kind of the present utility model.
Fig. 1 has described an embodiment of the present utility model.Have in this example in the taper outer tube body 1, outer tube body 1 of a steel and be lined with moulding diamond spar sintered pipes 3, the inner wall shape basically identical of moulding diamond spar sintered pipes 3 and outer tube body 1, and modified epoxy tackiness agent 2 (also can adopt other suitable bonding) is arranged at moulding corundum sintered pipes 3 and 1 of outer tube body.
Fig. 2 has described another embodiment of the present utility model.A cast iron outer tube body 21 that is made of two sections conical tubes is arranged in this example, be compounded with moulding corundum sintered pipes 3 by sticker layer 2 (employing silica gel) in the outer tube body 21.
The utility model also can adopt other embodiments.Adopt shapes such as square, hopper shape, elbow-shaped as outer tube body.
