Sewage disposal device for boiler drum

Abstract

The invention discloses a sewage disposal device for a boiler drum. The sewage disposal device for the boiler drum comprises a boiler drum body. The two sides of the boiler drum body are provided withthreaded connectors. The threaded connectors are fixedly connected with end plates. The top face of the boiler drum body is fixedly provided with an exhaust pipe. One side of the exhaust pipe is provided with a water inlet pipe, the water inlet pipe is fixed to the boiler drum body, and the top end of the water inlet pipe is provided with a pipe stopper. One side of the bottom face of the boilerdrum body is provided with a blow-off pipe. The bottom end of the blow-off pipe is fixedly provided with a close cover. The inner side of the boiler drum body is provided with a sewage disposal assembly. The sewage disposal assembly comprises two side plates and flexible rolling wheels. The sewage disposal device for the boiler drum has the beneficial effects that a push rod pushes a scraping plate to transversely move along the bottom wall of the boiler drum body so that scraping cleaning can be carried out on impurities of water and the impurities of the water can be pushed to the blow-off pipe to be discharged, cleaning of the impurities of the water is achieved, and the situation that the impurities of the water are accumulated on the bottom face of the boiler drum body and consequently the heating efficiency is affected is avoided.

Description

technical field [0001] The invention relates to the field of boiler auxiliary components, in particular to a cleaning device for a boiler drum. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The drum is an important part of the boiler. The boiler drum is simplified by Made of high-quality thick steel plate, it is a cylindrical container that receives feed water from the economizer, connects the circulation loop, and delivers saturated steam to the superheater in natural circulation and multiple forced circulation boilers. [0003] The applicant found that there are at least the following technical problems in the prior art: there is no cleaning component in the drum, and impurities in the water tend to accumulate on the bottom of the drum, whi...
