Description
Technical field
The present invention relates to the pipe transportation technology field of filling in mine slip, more particularly to a kind of shock proof resistance to bearing
Mill bend pipe.
Background technology
Consolidated fill is a very important part in filling in mine recovery process, and cemented backfilling technology is will to gather and add
The fine sand of work, gravel, block stone and broken spoil add appropriate Binder Materials according to proportioning, and casting resin is made after being mixed
Slurry, then filling slurry is delivered to the goaf in mine, the cementing obturator of some strength, control and improvement are formed in goaf
The movement and deformation of mine rock stratum.
Filling slurry is conveyed using pipeline mostly, and the pipeline of filling slurry is the key link of filling system.
Either using the self-flowing pastefill of filling slurry deadweight, or by the way of pump pressurized delivered, in vertical pipe and horizontal tube
The slip pressure that the pipe bent position that road is connected is subject to is maximum, the porch connection vertical pipe of bend pipe, the exit connection of bend pipe
Horizontal pipe, when slip flows from vertical pipe to horizontal pipe, the flow direction of slip occurs drastically to change in pipe bent position, now
Slip is very big to the impulsive force of the tube wall of bend pipe；Being particularly due to water hammer that the factors such as stream is unstable cause can also be right
The tube wall of bend pipe produces more strong impact power.Accordingly, it would be desirable to be fixed to bend pipe, bend pipe is prevented due to being rushed by larger
Hit power and produce so that bend pipe is chronically at fatigue state, and then cause the phenomenon that the service life of bend pipe shortens
Occur.It is much more live in the form of the pipe holder or tube hanger by winding pipe exit at horizontal pipe support, can so subtract
The vibration of little bend pipe, but but bend pipe can not be made well to resist powerful impulsive force so that the service life of bend pipe is relatively low；
Simultaneously as the hardness and density of filling slurry is big, grain shape irregular, and the transporting velocity of filling slurry is big, is filling
Extender paste will necessarily cause the generation wear phenomenon of the tube wall of pipeline, particularly in pipe bent position, filling slurry during transporting
The most serious is washed away to tube wall on the inside of the back of bend pipe so that the tube wall at the back of bend pipe occurs abrasion, worn and torn more serious
When so that there is perforation in the tube wall at back, at the scene, the tube wall at the back of bend pipe occurs the very high frequency of perforation；Therefore, bend pipe
Impact resistance and wearability all can play material impact to the service life of bend pipe.
Currently in order to the service life of bend pipe is improved, generally using the bend pipe of special thickening, or lined ceramicses, rubber etc.
The bend pipe of high-abrasive material, or the abrasion-proof bent tube made using alloy material, but complex manufacturing technology, price are high.Wherein, it is public
The number of opening discloses a kind of wear-resistant bend, including elbow for the patent of 202371369 U of CN, and elbow is provided with seal case, described
The bending section of elbow is located in seal case, and a confined space region is formed between the bending section and seal case of elbow.Sealing
Casing connects into seal cavity by arc, panel and end-plate, and after elbow tube wall is worn through, granular material can enter closed
Cavity area forms calculus block, and used as wearing layer, the patent improves the wearability of bend pipe to calculus block, but cannot improve bend pipe
Shock resistance, elbow by larger impulsive force can still occur vibration, when vibrate it is more serious when, it may appear that elbow with sealing
The phenomenon that casing is separated or seal case disintegrates, meanwhile, the abrasion of bend pipe is occurred mainly on the back side wall of bend pipe, and this is resistance to
The seal case sealing range of mill elbow is big, causes its production cost high.The patent of Publication No. CN204573429U is disclosed
A kind of coarse aggregate fills abrasion-proof bent tube, including a steel square bend pipe and wear-resisting room, and the wear-resisting room is the metal-back of five-surfac airtight,
The one side of its opening is welded on the outside tube wall at the right angle steel bend pipe turning, and the outside tube wall of right angle steel bend pipe is provided with
Pod apertures, by pod apertures are into wear-resisting room and are frozen into cementing piece, the method can improve the wearability of bend pipe to slip, but
The shock resistance of bend pipe cannot be improved, right angle steel bend pipe can still be occurred vibration by larger impulsive force, more serious when vibrating
When, it may appear that the phenomenon that right angle steel bend pipe is separated with wear-resisting room or wear-resisting room is disintegrated, meanwhile, the abrasion-proof bent tube is only protected directly
The back tube wall at 30 ° of angle steel bend pipe～60 ° of turnings, and the 0 of bend pipe °～30 ° and 60 °～90 ° turnings are in use
Abrasion can be equally produced, the potential safety hazards such as worn out, booster are equally existed during use.Therefore, bend pipe is due to opposing punching
The ability of hitting power is poor and cause the use still life-span of bend pipe relatively low, at the scene, it is still desirable to be replaced as frequently as bend pipe so that
The high labor intensive of workman, while affecting safety in production and the normal operation of filling system.
The content of the invention
