Description

A kind of manhole door for desulfurizing tower
Technical field
This utility model relates to field of chemical equipment, particularly relates to a kind of manhole door for desulfurizing tower.
Background technology
Desulfurizing tower in use, needs the most clear tower, with mud in avoiding tower, circulating pump pipeline will be produced serious abrasion, it is ensured that desulfurizer can be properly functioning.When clear tower, need all to bleed off the serosity in tower, then open manhole door and enter tower and carry out labor cleaning.As shown in Figure 1, existing manhole door and doorframe are by one group of clamping screw compact siro spinning technology, and arrange sealing rubber ring at the manhole door close fit with doorframe, and the operation therefore opening and closing manhole door is the most complicated, once sealing rubber ring assembling is not in place, then affect the sealing of whole tower body.
Summary of the invention
Goal of the invention of the present utility model is that solving existing manhole door opens and closes the problem that operation is complicated, and provides a kind of and open and close desulfurizing tower manhole door simple to operate, that compactness is good.
The purpose of this utility model is achieved by the following technical programs:
A kind of manhole door for desulfurizing tower, including the doorframe being located on tower body, doorframe is provided with the man-hole opening connected with tower body, door is provided with the door body matched with man-hole opening, it is characterized in that uniform one group of pressing plate in door body, this group pressing plate is arranged along door body one-week interval, pressing plate one end is stretched out outside door body, pressing plate one end is provided with open slot, uniform one group of clamping screw on described doorframe, each clamping screw one end is articulated and connected with doorframe, and each clamping screw respectively with the open slot corresponding matching of corresponding pressing plate, described clamping screw is provided with the locking nut with its threaded engagement.
Described clamping screw is the commercially available eyelet bolt in market, and locking nut is the commercially available wing nut in market.
On the basis of technique scheme, it is also possible to have technical scheme further below.
Described door body side is provided with at least one linking arm, linking arm one end is articulated and connected by the first hinged seat with doorframe, described linking arm is provided with waist elongated hole, the bearing pin corresponding matching of waist elongated hole and the first hinged seat, before rotating door body, the pin slide first passing through waist elongated hole and the first hinged seat coordinates, door body is translated along waist elongated hole length direction, until door body moves to specific bit and postpones, make door body rotate centered by the bearing pin of the first hinged seat again, thus avoid door body blocked up time door body and doorframe produce and interfere.
Described door body includes that cover plate, cover plate are provided with the cylinder matched with man-hole opening, and barrel end is closed, insulation material it is filled with in cylinder, it is provided with flanging along one week on cover plate, between flanging and cylinder, is provided with sealing ring, sealing ring side and the mutual corresponding matching of man-hole opening.
Described insulation material is the commercially available rock wool in market.
The beneficial effects of the utility model are simple in construction, good airproof performance, while facilitating switching manipulation, saving switch time, it is thus also avoided that during switching manipulation, door body interferes with doorframe, it is ensured that the thickness of door body.
The most just the utility model is described in further detail for accompanying drawings and embodiment.
