Description
Technical field
The present invention relates to a kind of pipe fitting, be specifically related to a kind of abrasion-proof bent tube being conveniently replaceable wearing plate.
Background technology
Abrasion-proof bent tube is applied in pneumatic transport ash disposal system, is that the important channel of transmission coal ash, its gateway and carbon steel pipe straight pipeline connect.The medium of transmission is gas-solid two phase flow, and gas is air, and solid is the lime-ash produced after coal combustion, and Main Ingredients and Appearance is the mixture that the hardness such as silicon dioxide, aluminium sesquioxide is higher, temperature about 350 DEG C, and pressure is 1.6MPa.When medium moves at straight pipeline, the direction of motion is identical with tube wall direction, hardly tube wall is produced abrasion.When medium is through curved pipe, then bend pipe back of the body arc can be formed impact and abrasion.
For solving this problem, current existing technology mainly uses bimetallic pipe bending technique and ceramic paster technology.Wherein, in bimetallic pipe bending technique, high-abrasive material is rich chromium cast iron, typically uses Technology of EPC, and high-abrasive material is cast in carbon steel pipe inwall, plays wear-resisting effect, outside its supporting role of carbon steel pipe.Compensate for rich chromium cast iron hardness height, the defect of poor toughness.Owing to abrasion-proof bent tube key wear position is positioned at the outer arc of bend pipe, therefore the wearing layer wall ratio of outer arc is thicker, and the wall ratio of inner arc is relatively thin.But bimetallic pipe bending technique there is also certain defect, on the one hand it is that during owing to using Technology of EPC, outer arc thickness is bigger, inner arc thickness is little, attempt makes material be fully utilized, even if being that inner arc thickness is smaller, being not without arranging any material, and the position of these high-abrasive materials arranged is not exposed to abrasion, the most inevitably cause waste of material, and high-abrasive material cost height causes its cost higher.On the other hand being formation dried shrimps waist in bend pipe, owing to there is the steel pipe of rounding off outside, surface be can't see；But there is obvious crest line inside, the rough flow resistance adding transmission medium of inwall.
In ceramic paster technology, high-abrasive material is wear-resistant ceramic, and Main Ingredients and Appearance is aluminium sesquioxide, during making, ceramic paster is made blockage, is attached at carbon steel elbow internal wall, also referred to as ceramic mosaic the most one by one.But ceramic paster technology there is also certain defect, such as the limited size of ceramic paster structure, if ceramic paster structure is big, will may go to sticks and staves more greatly because of its surface heat stress upon casting is complete.Using current little paster to inlay form, having a shortcoming clearly is that it defines a series of gap flowed to along medium.
Except both the above technological surprise, the most wear-resisting knapsack technology.The Main Ingredients and Appearance of knapsack is the materials such as carborundum, and carborundum passes through binding agent solidification bonded to each other, and outside is surrounded by steel plate groove, is welded in carbon steel bend pipe outer arc.Under nominal situation, transmit medium carbon steel pipe is the most worn out, then remove the high-abrasive material in knapsack that weares and teares.This structure is the most popular, but actual effect is undesirable, and internal carbon steel pipe is easy for worn out, and service life is short.
The most several Wear-resisting pipe fittings are all not easy dismounting.If after being worn through, need whole disassembling to change new again, bother very much.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of easily detachable abrasion-proof bent tube, solve the technical problem that bend pipe in prior art is not easy dismounting, cost is high.
For solving above-mentioned technical problem, the invention provides a kind of abrasion-proof bent tube being conveniently replaceable wearing plate, including hollow curve bend main body, it is characterized in that, also include that wearing plate, the cross section of described trap body are square, at outer arc, notch is offered on the upper surface of trap body, wearing plate is close on the outer arc inwall of trap body through notch, and outside sealing of notch is coated with angle steel, and angle steel is connected with trap body surface activity.
Further, the surface area of wearing plate is equal with the surface area of trap body outer arc side.
Further, it is provided with asbestos between angle steel and trap body surface.
Further, the two ends of described trap body are connected with hemispherical dome.
Further, the two ends of described trap body are connected with flange.
Further, trap body is carbon steel pipe.
Further, wearing plate is high chromium cast iron material casting.
Compared with prior art, the present invention is reached to provide the benefit that: the present invention only needs one piece of wearing plate, can substantial amounts of saving material, when changing wearing plate, the wearing plate worn and torn is taken out from notch, change new, and outside trap body can be recycled, and safeguards very convenient.The present invention processes simply, it is achieved save material, easy-to-dismount purpose.
