Abstract
The utility model belongs to an observing device for gas purifying chamber, and particularly relates to a push-pull type observation mirror for gas purifying chambers, which solves the problem of theprior gas purifying chamber that an observation mirror thereof can't be cleaned and performs practically no function. The push-pull type observation mirror for gas purifying chambers comprises a cone-shaped shield with the big mouth end welded on the wall surface of a gas purifying chamber and the small mouth end accommodating observation glass, wherein a baffle which can be pushed and pulled is arranged between the observation glass and the cone-shaped shield, a through hole type sight hole is opened on one side of the central line of the baffle in the vertical direction, and a blind hole isopened on the other side thereof. The utility model has the beneficial effects that the baffle is used to space out exhaust gas, so that flour dust can be prevented from adhering to the observation glass; and the observation glass on the outer side can be dismounted conveniently for cleaning even when the gas purifying chamber is under operation, thereby truly realizing the effective observation on the operation state of the inside of the gas purifying chamber.
Description
Technical field
The utility model belongs to the air-purifying chamber finder, is specifically related to the plug-type peephole of a kind of air-purifying chamber.
Background technology
Present smoke dust-removing equipment---sack cleaner or electric cloth deduster, in actual motion, because a variety of causes, it is damaged to cause dust-removal cloth-bag to take place, if at this moment untimely processing, exporting discharging on the one hand can exceed standard, on the other hand, contiguous cloth bag can be affected, and flow velocity increases near the broken bag, the wearing and tearing aggravation, thus cause that more cloth bags damage.If at this moment can in time judge the broken bag position, and be handled, will reduce the fault rate of sack cleaner greatly, prolong life of bag filter.The air-purifying chamber peephole is exactly in order in time to check the air-purifying chamber operation conditions, determines the broken bag position and the device that designs.
Usually all be at each air-purifying chamber metope two peepholes to be set, one of them disposes lighting device, opens the illumination shot-light, and by another peephole, the operations staff just can conveniently observe the situation of air-purifying chamber, pinpoints the problems, and in time handles.
Existing air-purifying chamber peephole, generally all adopt double-layer glass structure, inside and outside glass is fixed, and inner layer glass directly contacts with flue gas, like this, through operation after a while, dust in flue gas is just attached to glass surface, because inner layer glass is in the high-temperature flue gas, can't carry out wiping, therefore, at this moment see through peephole and just can't see the operation conditions of air-purifying chamber inside clearly, peephole performs practically no function.
Summary of the invention
The utility model can't wiping in order to solve in the prior art air-purifying chamber peephole, and the problem that performs practically no function provides a kind of air-purifying chamber plug-type peephole.
The utility model adopts following technical scheme to realize:
The plug-type peephole of air-purifying chamber, comprise that big opening end is welded in the cone-shaped hood that air-purifying chamber metope, osculum end are provided with sight glass, but the baffle plate of push-and-pull is set between sight glass and the cone-shaped hood, and a side of the center line of vertical direction has the window of through-hole form on the baffle plate, and opposite side is a blind hole.
The welding of cone-shaped hood osculum end has the inner flange of observing through hole, the inner flange outside connects the outward flange that has internal thread, establish the flange that screws of observing through hole with also having of its threaded engagement in the outward flange, screw between flange and the inner flange push-pull plate is set, screw the flange outer end sight glass is installed.
Screw the flange outer end and connect the glass supported flange, sight glass is installed on glass supported flange inboard, and sight glass periphery two sides all is provided with gasket seal.
The upper and lower strip through-hole that has of baffle plate, the connecting bolt of inside and outside flange is provided with fairlead and is through within the strip through-hole.On inner flange and the position that baffle plate contacts sealing ring is set.
The utility model compared with prior art has following beneficial effect: by baffle plate flue gas is separated, can prevent that dust is attached on the sight glass, and the sight glass in the outside also can be for convenience detach following under the state of air-purifying chamber operation, carry out wiping, thus the real operation conditions that realizes effectively observing air-purifying chamber inside.
Description of drawings
