Technical Field

The invention belongs to the field of wear and corrosion resistance of conveying pipelines, and relates to a wear-resistant conveying pipe.

Background

The pneumatic transmission pipelines in the power industry and the cement industry are seriously abraded and corroded. The existing anti-abrasion and anti-corrosion measures generally adopt a mode of lining ceramic plates to prolong the service life of the pipeline. However, because the adhesive for pasting the ceramic tiles is an organic material, the temperature tolerance is too low, the use temperature is not more than 80 ℃, the bonding strength is gradually reduced along with the temperature rise, and the bonding effect is lost when the use environment temperature is more than 150 ℃. Meanwhile, the anti-abrasion layer is composed of a plurality of ceramic chips, is not an integral structure, even if measures such as a mutual pressing structure are taken, one ceramic chip still falls off to cause a large area to fall off, so that the service life is low, generally only 1 to 2 years, because the organic binder is bonded with the ceramic chips on the inner wall of the pipeline mainly by organic binders, and the ceramic chips are easy to fall off under high temperature, thermal stress or mechanical stress due to the existence of seams. And the pneumatic conveying gas conveying temperature of a production unit is fluctuated, so that the ceramic chips can fall off due to the maintenance, the overhaul, the welding and the like of pipelines, and the service life is further shortened. Obviously, the organic bonding agent has poor temperature resistance, the non-integral structure is a short plate of the fire-resistant, corrosion-resistant and abrasion-resistant technology, in addition, the cost of the ceramic plate and the cost of the organic bonding agent are both high in the mode of pasting the ceramic plate, and the requirement on the surface cleanliness of the conveying pipe wall is high in the mode of pasting the ceramic plate, so that the construction cost is high.

Disclosure of Invention

The invention aims to design a wear-resistant conveying pipe, and aims to solve the problems that the existing conveying pipe is poor in corrosion resistance and wear resistance due to the fact that an adhesive for adhering ceramic chips is an organic material, the adaptability to the environment is poor when the temperature is too low, and an anti-wear layer is a non-integral structure consisting of a plurality of ceramic chips and falls off.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a wear-resisting conveyer pipe, includes the conveyer pipe, strengthens fastener and dope layer, strengthen the fastener layer welding at the conveyer pipe inner wall, strengthen the fastener layer and distribute for latticed whole or independent piece, the dope layer bonds on strengthening the fastener and bonds with the conveyer pipe inner wall.

Further, the reinforced fastener layer is a tortoise-shell net.

Furthermore, the reinforced fastener layer is a riveting nail, and the welding point interval of the riveting nail is 5-6 mm.

Further, the thickness of the reinforced fastener layer is 8-12 mm.

Further, the thickness of the coating layer is 15-20 mm.

Further, the coating of the coating layer is a superhard high-temperature ceramic matrix composite wear-resistant coating.

The invention has the beneficial effects that:

1. the wear-resistant coating is coated on the inner wall of a conveying pipe welded with a reinforced fastener layer such as a tortoise shell net or a riveting nail, the pasty wear-resistant coating is extruded and fully filled in the tortoise shell net or the riveting nail to jointly form a compact wear-resistant coating, and a fire-resistant, corrosion-resistant and wear-resistant layer is formed after curing and baking, so that a pasty material prepared from superhard high-temperature ceramic base powder and the conveying pipe form a firm whole through the welded tortoise shell net or the riveting nail, the wear-resistant and corrosion-resistant performance of the pipe is improved, and the problem that in the prior art, an organic binder is mainly bonded on the inner wall of the pipe through an organic binder in a bonding mode and has a seam, and the ceramic is easy to fall off under high temperature, thermal stress or mechanical stress is solved;

2. the manufacturing cost of the wear-resistant conveying pipe is reduced by 20-30% compared with the cost of pasting a wear-resistant ceramic wafer, the raw material cost of the wear-resistant conveying pipe is low, the requirement on the surface cleanliness of the conveying pipe wall is not high, the problems that the cost of ceramic wafers and organic adhesives are high in the mode of pasting the ceramic wafers in the prior art, and the requirement on the surface cleanliness of the conveying pipe wall is high in the mode of pasting the ceramic wafers in the prior art, so that the construction cost is high are solved, the thickness of a coating layer can be adjusted randomly according to needs, the parts with serious wear can be thickened properly under the condition that space is allowed, the whole service life is prolonged, and the ceramic wafers in the prior.
