Description

A kind of boiler uptake

Technical field

The utility model belongs to boiler technology field, and in particular to a kind of boiler uptake.

Background technique

The main function of boiler uptake exactly collects high-temperature flue gas, and flue gas is forced to turn to, and pushes flue gas It flows in the smoke-fire-tube of next group of backhaul.Therefore, relatively high to the sealing performance requirement of smoke box door and smoke box body, and to cigarette Case thermal insulation property also requires.Currently, the phenomenon that the generally existing smoke box surface temperature of domestic pan shell type Methods of Oil-Gas Fired Boiler is higher, is deposited In some potential safety problems.Radiation loss brought by high temperature increases, and also results in the waste of fuel energy.In addition, existing skill Smoke box door weight is big in art, and welded type hinge strength is inadequate, be easy to produce under the gravity of smoke box door deformation and open and It is more inconvenient to close.It is above existing in order to solve the problems, such as, need to design a kind of lightweight, sealing thermal insulation in boiler applications The good smoke box of energy.

Utility model content

That the technical problem to be solved by the utility model is to provide a kind of closure is good, save the energy and convenient for open one Kind boiler uptake.

The technical solution of the utility model is to provide a kind of boiler uptake comprising smoke box body and smoke box door, the cigarette Cabinet is ellipsoid, and there are observation panel, the observation panel material is high-temperature flame-proof glass for outside, is inside the smoke box Two return arrangement, the two return pipe both ends are equipped with air inlet and air outlet, described

Smoke box door has certain thickness, is circumferentially set as groove on smoke box door opening inner sidewall, on the smoke box door Equipped with sealing ring, the sealing ring is tongue shape, there is gap, periphery covering between the smoke box door and smoke box panel In smoke box panel range, the second sealing lining is provided in the gap between the smoke box door and smoke box panel, it is described It is filled with fire resistant heat preserving lining between the end face and end face outside of smoke box door, is filled with refractory insulating layer in the smoke box body.

Preferably, the utility model is equipped with support frame in the bottom of smoke box.

Further, the support frame is equipped with universal wheel.

The beneficial effects of the utility model are: providing a kind of lightweight, sealing thermal insulation performance good smoke box, structure utilizes two Backhaul arrangement, makes flue gas delay velocity of liquid assets, sealing ring is arranged at smoke box door, to reach the formedness of sealing.

Appended drawing reference: smoke box body 12, observation panel 1, smoke box door 2, handle 3, support frame 5, burner component 4, gasket 14, two Return duct 7, two return device 6, air inlet 9, gas outlet 19, universal wheel 15.

Specific embodiment

Below in conjunction with attached drawing, the technical solution of the utility model is further explained: a kind of boiler uptake comprising cigarette Cabinet 12 and smoke box door 2, the smoke box body 12 are ellipsoid, and there are observation panel 1,1 material of observation panel is for outside High-temperature flame-proof glass, is two return device 6 inside the smoke box body 12, and 6 both ends of two return device are equipped with air inlet 9 With gas outlet 19, the smoke box door 2 has certain thickness, is circumferentially set as groove on 2 hole inner sidewall of smoke box door, described Smoke box door 2 be equipped with sealing ring, the sealing ring be tongue shape, between having between the smoke box door and smoke box panel Gap, periphery are covered in smoke box panel range, and is provided in the gap between 12 panel of the smoke box door 2 and smoke box body Two sealing linings, are filled with fire resistant heat preserving lining, the smoke box body 12 between the end face and end face outside of the smoke box door 2 In be filled with refractory insulating layer, the utility model the bottom of smoke box be equipped with support frame 5, the support frame be equipped with universal wheel 15。

Above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, those skilled in the art It should be appreciated that the technical solution of the present invention is modified or equivalently replaced, without departing from the utility model technical side The objective and range of case, should all cover in the scope of the claims of the utility model.
