Background technology
In existing mining mortar delivery pipe road, conveyance conduit usually can due to abrasion premature failure, by delivery pipe
Road abrasion genetic analysis show that metal delivery tubes road is mainly failed by slurry wear, if selecting antifriction metal (AFM)
It is used as conveyance conduit, it is clear that cost will greatly improve, this extra earning that will be unfavorable for enterprise.Simultaneously as mortar is containing one
Determine the semifluid of moisture, therefore can all have accumulation and depositional phenomenon in conveying, if handling not in time, delivery pipe can be blocked
Road causes to convey operation stopping, sometimes it also occur that pipe explosion accident.In order to which conveyance conduit is enable to stablize conveying, technical staff
A variety of methods are devised to overcome mortar packing phenomenon, but result is unsatisfactory, therefore, technical staff changes thinking, thinks
Clogging is found by detecting the pressure in conveyance conduit in time, then by controlled discharge valve come pressure release, this method
The problem of conveyance conduit blocks has been well solved, still, since pressure-detecting device and electric control valve cost are higher, and has been conveyed
Pipeline is longer, and layout points are more, and input cost is larger, and later maintenance is costly, and marketing receives larger obstruction, such as
What provides mining mortar delivery pipe road that is a kind of not only wear-resisting but also can solving blockage problem, is that those skilled in the art research and develop
Subject.
Invention content
The goal of the invention of the present invention is：In view of the above problems, provide it is a kind of not only wear-resisting but also can solve block ask
The mining mortar delivery pipe road of topic, to solve the deficiency of existing conveyance conduit.
The technical solution adopted by the present invention is as follows：A kind of mining mortar delivery pipe road, including conveyance conduit, conveyance conduit
Inner wall is equipped with one layer of resistance to erosion layer, and conveyance conduit is equipped with the floating bleeder mechanism of hollow structure, floating bleeder mechanism and conveying
Pipeline fixed seal connection, and be mutually communicated, the one end of floating bleeder mechanism far from conveyance conduit is blind end, is divided floating
The inside of device along the radial direction of conveyance conduit, is equipped with blocking portion, floating seal portion and hydraulic oil portion successively from the near to the distant,

Aerial drainage can not only realize automation control, meanwhile, equipment therefor and simple in structure, operation and maintenance is convenient, manufacture cost compared with
Electric control gear is much lower, and practicability is stronger；
2nd, resistance to erosion layer of the invention is equal by the compound polyurethane material of the present invention using special compound polyurethane material
After the even inner wall coated in conveyance conduit, mortar generates impact wear to coating first, and the polyurethane adhesive in coating is tightly
Silica dioxide granule is bonded, adhesive strength is high, and silica dioxide granule is not easily to fall off, when polyurethane adhesive is further ground
When damage rupture is even peeled off, since silica dioxide granule hardness is far above polyurethane hardness, polyurethane cognition is selectively ground
It damages and silica dioxide granule is made gradually to show especially, as the silica dioxide granule of wear-resistant material, be highly resistant to mortar sand grains point
The cutting at angle and ditch dug with a plow effect, prevent coating from being further worn out, the silica dioxide granule shown especially forms one in coating surface
The silicon dioxide layer of layer hard wear resistant, and then make coating that there is outstanding flushing resistance, substantially increase the resistance to of conveyance conduit
Performance is ground, meanwhile, than selecting the mode input cost of antifriction metal (AFM) much lower by the way of coating, efficiently solve defeated
The problem of sending pipeline not wear-resisting；
3rd, conveyance conduit of the invention, it is adaptable, existing conveyance conduit need to be only reequiped, coats the defeated of resistance to erosion layer
Pipeline is sent, wearability greatly improves, and service life substantially extends, and has saved material cost and maintenance cost for enterprise, has been worth
Large-scale promotion application.
