Description

Air chamber inspection door of garbage incinerator

Technical Field

The utility model relates to an inspection door of an air chamber of a garbage incinerator, in particular to an inspection door with an observation window.

Background

In the operation process of the garbage incinerator, in order to observe whether the operation condition of mechanical parts at the bottom of the grate is good or not and whether fire leaks or not, an air chamber inspection door at the bottom of the grate needs to be opened frequently for checking. However, due to the influence of the high-temperature primary air at the bottom of the grate in operation, when an operator on site opens the air chamber inspection door, the primary air is usually stopped before the door is opened for checking in a safe period. Therefore, not only are troubles and unsafe hidden dangers brought to the work of field operators, but also the bottom condition of the fire grate in normal operation of the incinerator cannot be checked in real time, because primary air at the bottom of the fire grate is in an open state in normal operation, and the primary air is required to be stopped and checked for safety when the incinerator is opened and checked. Therefore, the air chamber inspection door which can conveniently and safely check the running condition of the bottom of the fire grate in real time without opening the inspection door needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a wind chamber inspection door of a garbage incinerator, which can accurately observe the running condition of the bottom of a grate of the incinerator in real time through a safe observation window, and improve the working efficiency and safety of field operators.

The technical scheme includes that the observation window is arranged in the middle of a door body, the flange is arranged on the observation window on the front side of the door body, the observation mirror is arranged in the flange, heat insulation cotton is filled in the door body, the handle is arranged on the front side of the door body, a connecting rod of the handle penetrates through the door body to protrude backwards and is connected with the observation mirror protection plate, and the handle can drive the observation mirror protection plate to swing through rotation so that the observation mirror protection plate can shield or open the observation window on the back side of the door body.

The window of the front observation window of the door body is smaller than the window of the back of the door body, so that a horn-shaped observation window with a small front and a large back is formed.

This with neotype theory of operation is through setting up tubaeform window on the door body to install the sight glass on the window, the rethread handle rotates the sight glass backplate and opens and close convenient from the extroversion-in observation, and inspection door inner cup and enclosing cover are steel sheet welded structure moreover, have changed the original casting structure of inspection door, make inspection door weight alleviate greatly, and it is also more convenient to make, has made things convenient for the field personnel operation simultaneously. The space between the inner cover and the outer cover of the inspection door is filled with heat insulation cotton, high-temperature smoke inside the air chamber can be well isolated from the external environment of the air chamber, and the heat insulation effect is achieved. Circular observation holes are formed in the panel of the inner cover and the outer cover of the inspection door, the observation holes in the inner cover are larger than the observation holes in the outer cover, and a reducer is arranged between the two observation holes. By adopting the design, a wider view of the inside of the air chamber can be obtained when the air chamber is observed from the outside. The inspection door sight glass is welded on the panel of the outer cover of the inspection door and corresponds to the circular observation hole on the outer cover of the inspection door. The inspection door mirror device is characterized in that a transparent circular lens is fixed in the middle of two circular flanges through bolts. The design is convenient for observation and replacement of the worn lens. The sight glass guard plate device is tightly attached to the panel of the inner cover of the inspection door, and the opening of the observation hole is controlled through round steel penetrating through the inspection door and a handle at the other end of the round steel. When observation is not needed at ordinary times, the protective plate device shields the observation hole on the inner cover of the inspection door, so that high-temperature air in the air chamber and dust particles in the air can be prevented from damaging the lenses. When observation is needed, the round steel handle at the upper part of the inspection door is rotated to drive the guard plate to rotate, so that the observation hole is opened, and the operation condition in the air chamber is observed.

The utility model has the advantages of simple and reasonable structure, convenient and safe operation, and can ensure that an observer can conveniently and intuitively observe the operation condition of the components of the indoor garbage incinerator.
