Film-type wall water pipe boiler inspection door structure

Abstract

The invention discloses a film-type wall water pipe boiler inspection door structure which comprises an embedded part which is fixedly arranged on a service port surrounding film-type wall, wherein a door seat plate is fixedly arranged on the embedded part, and a packaging cover plate is fixedly arranged on the outside of the door seat plate; an inner test port and an outer test port, an inner fire-observing port and an outer fire-observing port as well as an inner manhole and an outer manhole are respectively arranged on the door seat plate and the packaging cover plate in one-to-one correspondence; an inner fire-observing port cover plate is arranged on the inner fire-observing port, and the inner fire-observing port cover plate is articulated with the door seat plate; an openable manhole cover plate is arranged on the inner manhole, and test sensors are install in the inner test port and the outer test port; and an outer fire-observing cover plate is arranged on the outer fire-observing port, an openable outer manhole cover plate which is installed on the packaging cover plate is arranged on the outer manhole, and a driving device is arranged between the packaging cover plate and the inner fire-observing port cover plate. The film-type wall water pipe boiler inspection door structure provided by the invention has the advantages of simple structure, good heat insulation and heat preservation, comprehensive function and suitability for being applied to all film-type wall water pipe boilers.

Description

Technical field [0001] The invention relates to a boiler inspection door structure, in particular to a membrane wall water tube boiler inspection door structure. Background technique [0002] The boiler inspection door is installed at the inspection port of the boiler and is an essential part of the boiler. People enter the inside of the boiler through the boiler inspection door to install, build, repair, and clean the boiler. Membrane wall water tube boiler refers to a boiler in which the boiler wall, that is, the membrane wall, is composed of water tubes and flat steel welded into pieces. The traditional membrane wall water tube boiler inspection door has a simple structure, that is, a baffle is installed at the inspection port, and the baffle and the membrane wall are connected by bolts. Due to the high furnace temperature, the baffle plate and the bolts are easily deformed by heat, which causes the bolts and the inspection door to seize, making it difficult to open the insp...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the furnace, the baffle plate and bolts are easily deformed by heat, which will cause the bolts to seize the inspection door, making it difficult to open the inspection door and difficult to install it in place when reinstalling.

Moreover, this kind of inspection door structure has poor heat insulation effect and is easy to burn people. When monitoring the combustion inside the furnace or measuring the temperature and pressure in the furnace, the inspection door must be opened, and the work is cumbersome.
