Abstract
The present invention provides a kind of favorable expandability, extension type multistage chimney simple in construction, convenience in transport, it is characterised in that：Including rainhat, multi-layer cylinder, multi-layer cylinder raises gradually from outside to inside, it is adapted between the cylinder of adjacent layer with screw thread, the relatively outer one layer cylinder of internal layer cylinder moves up when threadingly rotating, at the same time the cylinder of more internal layer also moves, the rainhat is fixed on the cylinder upper end of innermost layer, outermost cylinder is fixed at the top of boiler, internal layer cylinder is provided with buckle relative to the terminal that outer one layer cylinder threadingly rotates, make at the position, relative position and angle can be kept constant between adjacent layer cylinder, one or more pairs of handles are all symmetrically arranged with outside the upper limb of every layer of cylinder, there can be more preferable impetus when rotated when the larger heavier-weight of cylinder size.
Description
Technical field
The present invention relates to a kind of special equipment, the high pressure injection steam boiler used in especially a kind of petroleum industry heavy crude heat extraction is special
Use equipment.
Background technology
Uphole steam generator is the special steam injection equipment of oilfield exploitation viscous crude, is to utilize caused HTHP moist steam
Oil well is injected, the crude oil in heated oil reservoir, so as to increase the mobility of viscous crude, can greatly improve thick to reduce the viscosity of viscous crude
The recovery ratio of oil.Subject matter existing for existing injection boiler is that force ventilation load is essentially consisted on blower fan, and chimney is taken out
Power is compared to very little, but upper road movement of the height of chimney to injection boiler has restrictive function, if the height adjustable of chimney
The upper road movement of injection boiler will also optimize.
The utility model of application number 201020240036.4 entitled " Telescopic chimney for high pressure steam injection boiler " provides one
Kind solution method, the extension type chimney are made up of cylinder, expansion link and rainhat, and cylinder is divided into two parts up and down, upper shell
Freely it can be moved in lower shell, lower shell is fixed at the top of boiler, and upper shell is fixedly connected with expansion link, and expansion link is fixed
At the top of boiler, expansion link is moved up and down by machinery, hydraulic-driven or folding sliding type.The program is simple in construction, uses
And convenience in transport, but this mode only has two sections, and design limits causes autgmentability deficiency.
The content of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of favorable expandability, simple in construction, convenience in transport stretched
Contracting formula multistage chimney, it is characterised in that：Including rainhat, multi-layer cylinder, multi-layer cylinder raises gradually from outside to inside, adjacent layer
It is adapted between cylinder with screw thread, the relatively outer one layer cylinder of internal layer cylinder moves up when threadingly rotating, at the same time more
The cylinder of internal layer also moves, and the rainhat is fixed on the cylinder upper end of innermost layer, and outermost cylinder is fixed on boiler
Top.
Further, internal layer cylinder is provided with buckle relative to the terminal that outer one layer cylinder threadingly rotates, and makes in the position
When putting, between adjacent layer cylinder relative position and angle can be kept constant.
Further, one or more pairs of handles are all symmetrically arranged with outside the upper limb of every layer of cylinder, when cylinder size is larger
There can be more preferable impetus during heavier-weight when rotated.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1- rainhats, 2- screw threads, 3- cylinders.
Embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
Referring to a kind of Fig. 1 favorable expandability provided by the invention, extension type multistage cigarette simple in construction, convenience in transport
Chimney, it is characterised in that：Including rainhat 1, multi-layer cylinder 3, multi-layer cylinder 3 raises gradually from outside to inside, the cylinder 3 of adjacent layer it
Between be adapted with screw thread 2, threadingly the relatively outer one layer cylinder 3 of internal layer cylinder 3 moves up during 2 rotation, at the same time interior
The cylinder 3 of layer also moves, and the rainhat 1 is fixed on the upper end of cylinder 3 of innermost layer, and outermost cylinder 3 is fixed on pot
Furnace roof portion.Relative to outer one layer cylinder 3, threadingly 2 terminals rotated are provided with buckle to internal layer cylinder 3, make at the position, phase
Relative position and angle can be kept constant between adjacent bed cylinder 3.
Claims (3)
