Ash bucket access door of pulse bag type dust collector

Abstract

The invention discloses an ash bucket access door of a pulse bag type dust collector. The ash bucket access door comprises an access door body arranged on the ash bucket wall of the pulse bag type dust collector and outside an access opening, and the access door body comprises an inner access door, an outer access door, a connection block and a rotation shaft. The connection block and the rotation shaft are arranged between the inner access door and the outer access door, and the thickness of the connection block and the rotation shaft is equal to that of the ash bucket wall. The rotation shaft is arranged at a left lower corner of the access door body which can be rotatably arranged on the ash bucket wall through the rotation shaft. Areas of the inner access door and the outer access door are larger than the area of the access opening. When the ash bucket access door is closed, users can only use a bolt to insert in a first location hole and a second location hole in the ash bucket wall for fixing, and the connection block is vertically arranged and close to the left lateral wall of the access opening. When the ash bucket access door is opened, the users only need clockwise rotate the access door body for 90 degrees, the connection block is located in a groove. The ash bucket access door of the pulse bag type dust collector avoids dust leakage in an ash bucket of the pulse bag type dust collector, and can be free of damage after long-time frequent use.

Description

technical field [0001] The invention relates to an inspection door, in particular to an inspection door arranged on an ash hopper of a pulse bag type dust collector. Background technique [0002] A dust collector is a device that separates dust from flue gas. There are many types of dust collectors, among which the pulse bag filter is a relatively new type of dust collector. The pulse bag filter includes an ash hopper, and an inspection door is provided on the ash hopper for easy maintenance of the ash hopper. The ash hopper inspection door of the existing pulse bag filter is connected and fixed on the outer wall of the ash hopper by multiple bolt fasteners. Although the structure is simple, the dust in the ash hopper is easy to leak out during use. Pollution of the surrounding environment; there are also hinges connected to the outer wall of the ash hopper, and then fixed on the outer wall of the ash hopper by bolt fasteners. There is a sealing device between the door an...
