Abstract
The utility model discloses a novel power plant coal falling elbow with a detachable circular corner wear-resisting liner plate. The novel power plant coal falling elbow with the detachable circular corner wear-resisting liner plate comprises an elbow body. A coal inlet liner plate and a coal outlet liner plate are respectively fixed on an impact wear inner wall of the elbow body. The novel power plant coal falling elbow with the detachable circular corner wear-resisting liner plate is characterized in that a wear-resisting liner plate is bent to the circular corner wear-resisting liner plate matched with the coal falling elbow in angle through a plate bending machine and the circular corner wear-resisting liner plate is fixed on the impact wear inner wall of the elbow portion of the elbow body through countersunk bolts and nuts. The two ends of the circular corner wear-resisting liner plate are welded and fixed with the lower end of the coal inlet liner plate and the upper end of the coal outlet liner plate of the impact wear inner wall of the elbow body of the coal falling elbow. The novel power plant coal falling elbow with the detachable circular corner wear-resisting liner plate has the advantages of being capable of improving the coal flowing performance, preventing the coal falling elbow from being blocked by coal and prolonging the service life of the coal falling elbow, convenient to disassemble and assemble, simple to manufacture and capable of reducing the improvement cost. The outer wall of the coal falling elbow and the coal inlet liner plate and the coal outlet liner plate of the original impact wear inner wall do not need to be replaced, the novel power plant coal falling elbow with the detachable circular corner wear-resisting liner plate is only installed on the impact wear inner wall of the coal falling elbow, and therefore the continuous operation of a coal feeding system is guaranteed.
Description
Technical field
The utility model relates to thermal power plant's coal spout abrasion-proof backing block, especially relates to power plant's coal breakage bend pipe of the detachable fillet abrasion-proof backing block of a kind of Novel belt.
Technical background
At present, the non-impact of domestic newly-built thermal power plant coal breakage bend pipe and non-wearing and tearing wall adopt the Q235 general steel plate, the impact wear wall then is that the compound wear-resisting steel plates of complex high-chromium alloy cast iron material on the Q235 general steel plate is made, and interior lining panel adopts countersunk-heat bolt to be connected with the coal breakage bend pipe.And old power plant coal breakage bend pipe or without the inner liner abrasive resistant steel plate, or take common wear-resisting steel plate as main.Yet, since interior lining panel be between across lining at the outer wall of coal breakage bend pipe, and the pipe bent position at the coal breakage bend pipe is to disconnect installing, after impacting through long coal stream, the interior lining panel serious wear, even can be worn through and cause coal breakage bend pipe outer wall to damage, thereby reducing the service life of coal breakage bend pipe, impact is operation normally.And the poor pipe bent position at the coal breakage bend pipe of the coal water conservancy diversion that aqueous ingredients is high is easily stopped up.Then cost is too high all to change the coal breakage bend pipes, and affects power plant and move continuously.
Summary of the invention
The purpose of this utility model is to provide power plant's coal breakage bend pipe of the detachable fillet abrasion-proof backing block of a kind of Novel belt, and it can strengthen the high coal stream of flowing power, especially aqueous ingredients of coal stream, prevents that coal stream from stopping up, and guarantees the continuity of coaling system; And its convenient disassembly is convenient to the coal breakage bend pipe of old power plant is transformed, and processing is simple, and is convenient and practical.
The purpose of this utility model is achieved in that
Power plant's coal breakage bend pipe of the detachable fillet abrasion-proof backing block of a kind of Novel belt, comprise the bend pipe body, be fixed with respectively coal inlet interior lining panel and coal outlet interior lining panel at the coal inlet of bend pipe body impact wear inwall and coal outlet, feature is: abrasion-proof backing block is curved the fillet abrasion-proof backing block that matches with coal breakage bend pipe angle with angle bender, respectively be processed with a countersunk-heat bolt hole at the two ends of fillet abrasion-proof backing block, two ends in the pipe bent position of bend pipe body respectively are processed with a bend pipe fixed orifice, countersunk-heat bolt passes countersunk-heat bolt hole and bend pipe fixed orifice, pass behind the outer wall of pipe bent position of bend pipe body fasteningly with nut fastener, the fillet abrasion-proof backing block is fixed on the pipe bent position impact wear inwall of bend pipe body.
The two ends of the fillet abrasion-proof backing block of being made by the high-chromium alloy cast-iron material are welded and fixed with the lower end of the coal inlet interior lining panel of coal breakage bend pipe body impact wear inwall and the upper end of coal outlet interior lining panel respectively.
The utility model is that the pipe bent position at traditional coal breakage bend pipe impact wear inwall is equipped with detachable fillet abrasion-proof backing block, coal stream flows to from the coal inlet of coal breakage bend pipe, flow through and flow out from coal outlet again behind the fillet abrasion-proof backing block of pipe bent position impact wear inwall of bend pipe body, like this, coal stream is the direct inwall of impact wear pipe bent position not just, outer wall that more can worn out coal breakage bend pipe, thus service life of coal breakage bend pipe prolonged.Because abrasion-proof backing block is made by the high-chromium alloy cast-iron material, and the high-chromium alloy cast-iron material has higher intensity and toughness, therefore to abrasion-proof backing block be curved the fillet abrasion-proof backing block that matches with coal breakage bend pipe angle with angle bender, to guarantee effective installation of abrasion-proof backing block.This abrasion-proof backing block so that the coal fluidity is better, has reached the purpose that prevents coal breakage bend pipe chute blockage owing to be designed to fillet.
The utlity model has improve the coal dust flowing power, prevent coal breakage bend pipe chute blockage, prolong the coal breakage bend pipe service life, remove and install conveniently, make simple, greatly reduce the advantage of improvement cost, it is on the basis of the outer wall that need not change the coal breakage bend pipe and original impact wear inwall coal inlet interior lining panel and coal outlet interior lining panel, only get final product in the installation of coal breakage bend pipe impact wear wall, guaranteed that coaling system moves continuously.
