Abstract
The utility model discloses an inspection window of a wet type dust removal fan, and relates to structure of the inspection window of the dust removal fan. The inspection window of the wet type dust removal fan comprises an installation seat. The installation seat is connected with a decorative cover, a sealing pad is arranged between the installation seat and the decorative cover, a slot is arranged in the decorative cover, a circlip for hole is arranged in the slot, an installation boss is arranged in the decorative cover in a siamesed mode, the installation boss is arranged on the inner side of the circlip for hole, two O-shaped sealing rings and a sight glass are arranged between the circlip for hole and the installation boss, and the sight glass is arranged between the two O-shaped sealing rings. The installation seat is welded on the wet type dust removal fan, the sight glass is arranged between the two O-shaped sealing rings, and the sight glass and the two O-shaped sealing rings are arranged in the decorative cover and tightly clamped by the circlip for hole, so the sight glass of the inspection window is sealed tightly, no matter positive pressure or negative pressure the sight glass of the inspection window suffers, the sight glass of the inspection window can be sealed tightly, water leak and air leak are prevented, and the circlip for hole enables a new sight glass to be replaced without screwing off the decorative cover when the sight glass is damaged. The sealing pad is arranged in the decorative cover, and the sealing pad can be sealed tightly when the decorative cover and the installation seat are screwed tightly.
Description
Technical field
The utility model relates to the dust arrester that is matched in the development machine use, relates in particular to the structure of the observation port of dedusting fan.
Background technology
Wet-type dust removal fan for mine be underground mine use in ventilate, one of the capital equipment of dedusting.Because the underground work condition is more abominable, and observation port all is installed on the Wet-type dust-removal fan, in order to can find fast and accurately problem points when machine breaks down, and can deal with problems timely.But there is following shortcoming in the observation port of installing on the Wet-type dust-removal fan at present: observation port is smaller, easily leaks, leaks gas, and changes inconvenient.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of easy accessibility to be provided, good airproof performance, the observation port of the Wet-type dust-removal fan that range of observation is large.
The purpose of this utility model is achieved in that a kind of observation port of Wet-type dust-removal fan, comprise mount pad, connect decorative cover on the mount pad, between mount pad and the decorative cover sealing mat is set, in the described decorative cover draw-in groove is set, circlip for hole is set in the draw-in groove, disjunctor arranges installation base in the decorative cover, installation base is arranged on the inboard of circlip for hole, and two O-ring seals and visor are set between circlip for hole and installation base, and visor is arranged between two O-ring seals.
Mount pad is welded on the Wet-type dust-removal fan, visor is placed between two O-ring seals, and be installed in the decorative cover, with the circlip for hole chucking, can make observation port visor place close sealing, no matter the observation port visor is subject to malleation or negative pressure, can both close sealing, prevent from leaking, leaking gas, and circlip for hole can when visor damage, needn't screw off decorative cover and also can change new visor.Sealing mat is installed in the decorative cover, can close sealing when decorative cover screws with seat.
