一种锅炉冷灰斗除焦工具A boiler cold ash hopper decoking tool

技术领域technical field

本实用新型涉及锅炉除焦技术领域，特别是一种锅炉冷灰斗除焦工具。The utility model relates to the technical field of boiler decoking, in particular to a boiler cold ash hopper decoking tool.

背景技术Background technique

结焦是锅炉运行中比较普遍的问题，在锅炉运行过程中，由于煤的燃烧、炉内传热、煤质的结焦特性、煤灰粒子在炉内运动以及煤灰与管壁间的粘附等原因造成结焦，锅炉正常运行时，这些焦块会通过自然脱落或锅炉吹灰等方式落入锅炉的冷灰斗中，再经过冷灰斗底部挤渣头挤碎后排出炉外。然而，在实际的运行中往往会出现短时间内焦块大面积脱落，造成锅炉的冷灰斗大面积的积焦现象，使焦块无法落入底部渣井的挤渣头位置，从而无法通过挤渣头挤压后排出，造成焦块大面积堆积，给锅炉安全稳定运行带来极大的隐患，此时需要人工协助将大焦块破碎，使其落入挤渣头位置，待挤碎后，再将焦块排出锅炉。Coking is a common problem in boiler operation. During the operation of the boiler, due to the combustion of coal, heat transfer in the furnace, the coking characteristics of coal, the movement of coal ash particles in the furnace, and the adhesion between coal ash and the tube wall, etc. The reason is coking. When the boiler is in normal operation, these coke lumps will fall into the cold ash hopper of the boiler through natural shedding or boiler soot blowing, and then be crushed by the slag squeezing head at the bottom of the cold ash hopper and then discharged out of the furnace. However, in actual operation, the coke lumps often fall off in a large area in a short period of time, resulting in a large area of coke accumulation in the cold ash bucket of the boiler, so that the coke lumps cannot fall into the position of the slag extrusion head of the bottom slag well, and thus cannot pass through. The slag extruding head is extruded and discharged, resulting in large-scale accumulation of coke blocks, which brings great hidden dangers to the safe and stable operation of the boiler. At this time, manual assistance is required to break the large coke blocks so that they fall into the position of the slag extruding head and are to be crushed. After that, the coke lumps are discharged from the boiler.

在实际运行中，冷灰斗内的焦块破碎常采取的措施有化学除焦(喷晒除胶剂)和人工机械除焦两种，由于种种原因多采用的是人工破碎除焦，即在锅炉运行时，通过冷灰斗处的观察孔或人孔使用工具对不能排出冷灰斗的大焦块进行破碎。常采用的除焦方法有：用长钢钎捅焦，用长铁钩钩焦等方式，但是由于受到作业空间和作业环境的影响，造成：1、作业效率低。因焦块相对较硬，破碎焦块无专用的工具，通过钢钎等工具很难破碎。2、作业难度大。对冷灰斗除焦只能通过人孔作业，作业空间小，作业平台具有局限性，作业半径小，同时炉膛内温度较高，长时间的连续作业，对作业人员安全隐患大。In actual operation, the measures often taken for coke block crushing in the cold ash hopper include chemical decoking (spraying and drying glue remover) and manual mechanical decoking. When the boiler is running, use tools to crush the large coke blocks that cannot be discharged from the cold ash hopper through the observation hole or manhole at the cold ash hopper. Commonly used decoking methods include: poking the coke with a long steel drill, hooking the coke with a long iron hook, etc., but due to the influence of the working space and working environment, resulting in: 1. Low operating efficiency. Because the coke block is relatively hard, there is no special tool for breaking the coke block, and it is difficult to break through tools such as steel drills. 2. The work is difficult. The decoking of the cold ash hopper can only be done through manholes, the working space is small, the working platform is limited, the working radius is small, and the temperature in the furnace is high, and the continuous operation for a long time poses a great safety hazard to the operators.

When the fixedsleeve 102 is close to the split The end of thewedge block 101a is provided with areserved air hole 102a (the number is not fixed), which can satisfy the ventilation of compressed air and is used to cool thesplit wedge block 101a, thehydraulic splitter 101 and the fixedsleeve 102. When theextension sleeve 201 needs to be connected, it can be First, connect theconnection sleeve 104 to one end of the fixedsleeve 102 by screwing, and then connect one end of theextension sleeve 201 to the other end of the fixedsleeve 102 through theexternal thread 201c. At this time, the fixedsleeve 102 and theextension sleeve 201 One end will be locked by the connectingsleeve 104, and at the same time, thelocking hole 201d needs to be aligned with thepositioning hole 104a. When the two are aligned, the fixingbolt 104b is used to penetrate through for secondary locking and fixing, so as to avoid the fixedsleeve 102 and theextension Cannula 201 creates separation.
