Abstract
The utility model relates to the technical field of pressure vessel manufacture, in particular to a heat exchanger capable of being disassembled and assembled quickly. Heat exchangers are widely applied to petroleum processing enterprises and chemical engineering enterprises, wherein when a flange heat exchanger of an outer head cover, a lateral flange heat exchanger of the outer head cover, a flange heat exchanger of a tube box and a lateral flange heat exchanger of the tube box are installed, assembled, repaired and disassembled, because a plurality of bolts are needed, people need to spend a lot of time to finish the processes; and because the repair time is long, the enterprise benefit is lost. In the utility model, a bolt hole on a heat exchanger flange is designed into a connecting shape of a big circular arc and a small circular arc, the diameter of the big circular arc is larger than the that of the diagonal of a matched nut, and the diameter of the small circular arc is larger than the diameter of a matched bolt and smaller than the diameter of the diagonal of the matched nut. In the assembling process, after the nut is sleeved on the bolt firstly, the bolt extends out of the big circular arc, and then, the bolt is pushed into the small circular arc to lock the nut. In the disassembling process, the bolt is pushed into the big circular arc from the small circular arc, and then, the bolt sleeved with the nut is taken out.
Description
One, technical field
The utility model relates to pressure vessel manufacturing technology field, a kind of specifically fast demountable formula heat exchanger.
Two, background technology
Heat exchanger is widely used in PETROLEUM PROCESSING, chemical enterprise, outer skull flange heat exchanger wherein, outer skull side flange heat exchanger, channel flange heat exchanger, tube case side flange heat exchanger are when installing assembling, repair demolition, because many bolts are arranged, the expensive time, just can finish.Because the repair time is long, the performance of enterprises incurs loss.
Three, summary of the invention
The purpose of this utility model provides a kind of fast demountable formula heat exchanger, and it can effectively improve assembling, dismounting speed, reduces labor intensity.
The technical solution of the utility model is that the bolt hole on the heat exchanger flange is the shape that is connected of an orthodrome and little circular arc, the orthodrome place is for moving back keyhole, its diameter is greater than the cornerwise diameter of joining nut, roundlet arc place is tight keyhole, its diameter is greater than the diameter of bolt, less than the cornerwise diameter of joining nut.
The utility model is in when assembling, earlier bolt worn (not disposing pad during these flanges assemblings) after the top nut, stretches into from orthodrome, then bolt pushed roundlet arc place locking nut.During dismounting, then earlier nut is unscrewed movingly, pushed the orthodrome place from the roundlet arc, the bolt that will wear nut takes out.
The utility model has the advantages that owing to reduced wearing and dismantlement work of nut, thereby many times have been reduced, alleviate working strength of workers, accelerated installation assembling, the repair demolition speed of heat exchanger. owing to shortened the repair time, improved economic benefit of enterprises.
Four, description of drawings
Fig. 1 is a heat exchanger flange arrangement schematic diagram of the present utility model
Fig. 2 is the diameter schematic diagram at bolt hole orthodrome of the present utility model place
Fig. 3 is the cornerwise diameter schematic diagram of nut
Five, the specific embodiment
1 flange, 2 moves back keyhole, 3 tight keyholes among the figure.
From Fig. 1, Fig. 2, Fig. 3 as can be known, bolt hole on the heat exchanger flange 1 is the connecting-type shape of an orthodrome and little circular arc, the orthodrome place is for moving back keyhole 2, its diameter is greater than the cornerwise diameter of joining nut, roundlet arc place is tight keyhole 3, its diameter is greater than the diameter of bolt, less than the cornerwise diameter of joining nut.
