Description
Technical field
The utility model is related to a kind of anti-tampering air locks in dedusting air port, belong to and build ship technical field.
Background technology
Dust phenomenon is blown in the appearance of the non-carbon steel place dedusting suction inlet in electromechanics workshop at present, mainly due to carbon steel place with it is non-
The deduster in carbon steel place is to share a Ventilator Room, and when carbon steel place dust removal machine works, its outlet air is through certain pressure
Non-carbon steel place is flowed to by the outlet of non-carbon steel dust removal machine, so that originally clean construction site generates dust and flue dust, shadow
The construction in non-carbon steel place has been rung, has not also met non-carbon steel roustabout skill requirement（Isolate dust）.
In order to solve problem above, typhoon shutter, but computer room narrow space need to be increased in pipeline, and pipeline increases air lock and needs
Tens thousand of member purchase costs, construction time length influence production.
Utility model content
Technical problem to be solved in the utility model is that provide a kind of dedusting air port for the above-mentioned prior art anti-tampering
Air lock closes air lock turnover panel by dead weight, mounted on fan outlet, both can reach non-carbon steel place dust removal machine in non-operation from
It is dynamic to close, work can be automatically opened by pressure again in operation, thoroughly solve the problems, such as the dirt of falling soot blowing.
The technical scheme in the invention for solving the above technical problem is：A kind of anti-tampering air lock in dedusting air port, it is wrapped
Seat ring is included, left and right is arranged in parallel with the first trunnion and the second trunnion on the seat ring, and the first wind is provided on first trunnion
Plate is provided with the second aerofoil on second trunnion, and the first aerofoil front is provided with the first Weight plate, first counterweight
Plate is located on the right side of the first trunnion, and the second aerofoil front is provided with the second clump weight, and second clump weight is located at the second ear
On the right side of axis, the first limited block and the second limited block are respectively arranged at left and right sides of the seat ring, first limited block is located at the
On the upside of one aerofoil left margin, second limited block is located on the right of the second aerofoil along downside.
Compared with prior art, the utility model has the advantage of：
1st, the utility model closes air lock turnover panel by dead weight, mounted on fan outlet, both can reach the dedusting of non-carbon steel place
Machine is automatically closed in non-operation, can automatically open work by pressure again in operation, thoroughly solve the problems, such as the dirt of falling soot blowing；
2nd, the utility model makes simple, and cost is extremely low, ingenious in design, solves two-way suction inlet well and interferes with each other,
The problem of pouring in down a chimney dust.
