Discharge pipe assembly for boiler drum

Abstract

The invention discloses a discharge pipe assembly for a boiler drum. The discharge pipe assembly for the boiler drum comprises a discharge pipe body, a pipe joint is fixed on the top face of the discharge pipe body, a plurality of mounting holes are formed in the pipe joint, and a sealing cover is fixed on the bottom face of the discharge pipe body; a plurality of supporting frames are fixed on the inner side wall of the discharge pipe body, a protective sleeve is fixed among the plurality of supporting frames, and a top cover is fixedly connected to the top face of the protective sleeve; anda mounting groove is formed in the protective sleeve, the mounting groove is fixedly connected with one end of a pressure spring through a clamp hook, and the other end of the pressure spring is fixedly connected with a limiting plate through the clamping hook. The discharge pipe assembly for the boiler drum has the beneficial effects that a pressure plate is driven to descend to be separated fromthe discharge pipe body due to the fact that the gravity of dirt is larger than the elasticity of the pressure spring in a process of opening the sealing cover for dirt discharging so that the dirt discharging which can be smoothly carried out is realized; when the dirt discharging is finished, the pressure spring releases the compression stroke of the pressure spring to drive the pressure plateto automatically return to close the discharge pipe body, so that automatic opening and closing of the discharge pipe body can be realized, and the finishing of the dirt discharging which can be timely notified to an operation personnel is facilitated.

Description

technical field [0001] The invention relates to the field of boiler auxiliary components, in particular to a blowdown pipe assembly 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 for natural circulation and multiple forced circulation boilers, which accepts the feed water from the economizer, connects the circulation loop, and delivers saturated steam to the superheater. Generally, the boiler drum needs to be installed with a sewage pipe. The dirt in the drum is discharged to avoid the dirt affecting the heating efficiency of the drum. [0003] The applicant found that there are...
