Background technology
China is grain-production big country and consumption big country, according to statistics, in threshing, drying, storage, fortune after China's grain harvest
Loss during defeated, processing, consumption etc. is up to 18% or so, considerably beyond as defined in FAO (Food and Agriculture Organization of the United Nation) 5% mark
It is accurate.In these losses, every year because of climate reasons, cereal has little time to dry or not up to safe moisture causes to go mouldy, germinateed
The grain of loss is up to 5%, if being calculated by 500,000,000 ton-grain food is produced per year, is eaten equivalent to 25,000,000 ton-grain, if eating for each person every day
500g grains, it is available for 6.8 ten thousand people edible 1 year.Therefore, the mechanization of grain dry is more even more important than the mechanization of farm work,
It is cereal high yield, the important leverage condition of good harvest.Hot-blast stove is the key equipment in foodstuff adustion system.
At present, conventional tubular exchanger uses upper and lower welding technique, exchanges pipe two and uses full weld with heat exchanger plate
Connection, as long as there is one to exchange pipe leakage in heat-exchange tube, whole exchanger must be disassembled, or even scrap.It is but hot
The maximum position of exchanger probability of damage is located at the position being connected with combustion chamber, and it determines the life-span of whole exchanger substantially.
Utility model content
The purpose of this utility model is to provide a kind of replaceable tubular exchanger, to solve above-mentioned technical problem.
The replaceable tubular exchanger of the present invention, connected using living, Nesting Technique, high temperature side heat-exchanger tube uses combined type knot
Structure, it is replaceable pipe that the superiors one, which cut exchange pipe, is mobilizable, the exchange Guan Weiyi roots of the following all length in upper strata, long to hand over
Pipe lower end is changed to be welded and fixed with lower power board.Upper and lower two exchange one sleeve pipe of increase among pipe, and 2 root pipes are connected.Can be more
The upper end for changing pipe is fixed on power board using a high temperature resistant cast iron nesting.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of replaceable tubular exchanger, it is characterised in that：Including framework, the framework both sides are provided with shrouding, the frame
Frame top and the bottom are respectively equipped with power board, lower power board；Centre is provided with median septum；
The lower portion is vertically arranged with heat-exchange tube, and four groups of the heat-exchange tube point is stood, and first group is stood and leaned on for high temperature
Nearly combustion chamber, stood for high temperature group, high temperature group grade separation changes pipe as two sections, and a upper section is replaceable pipe, is fixed below replaceable pipe
Pipe, fixing pipe bottom use with lower power board and are welded and fixed；Replaceable pipe lower end is connected by straight-through sleeve pipe with fixing pipe, can
The upper end for changing pipe passes through upper power board, and is connected with cast iron upper sleeve cover；
The vertical heat-exchange tube of other groups is separately fixed on upper and lower power board by the way of welding up and down.
Preferably, the cast iron upper sleeve cover is movable part, cross section is circle, and up big and down small, lower diameter is than upper exchange
The small 0.5mm of bore dia opened up on plate, cast iron upper sleeve cover lower end are inserted on upper power board in the hole opened up and fixed, several
Refractory cement sealing is poured between cast iron upper sleeve cover.
The beneficial effects of the utility model are：
The present invention provides a kind of replaceable tubular exchanger, is connected using living, Nesting Technique, high temperature side heat-exchanger tube uses
Fabricated structure, it is replaceable pipe that the superiors one, which cut exchange pipe, if breakage occurs for replaceable pipe, can will exchange the replaceable pipe of pipe
Part is individually replaced, and avoids exchanger is overall because of the damage of this section exchange pipe from scrapping.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face with specific embodiments and the drawings, the utility model is expanded on further, but following embodiments are only of the present utility model excellent
Embodiment is selected, and it is not all.Based on the embodiment in embodiment, those skilled in the art are not making creative work
Under the premise of obtain other embodiments, belong to protection scope of the present invention.
Specific embodiment of the utility model is described below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of replaceable tubular exchanger, it is characterised in that：Including framework 1, the both sides of framework 1 are provided with
Shrouding, the top and the bottom of framework 1 are respectively equipped with power board 1.1, lower power board 1.2；Centre is provided with median septum 1.3；
Heat-exchange tube 2 is vertically arranged with inside framework 1, the heat-exchange tube 2 divides four groups to stand, first group stand for high temperature it is close
Combustion chamber, being stood for high temperature group, high temperature group grade separation changes pipe as two sections, and a upper section is replaceable pipe, is fixing pipe below replaceable pipe,
Fixing pipe bottom uses with lower power board 1.2 and is welded and fixed；Replaceable pipe lower end is connected by straight-through sleeve pipe 2.2 with fixing pipe
Connect, the upper end of replaceable pipe passes through upper power board 1.1, and is connected with cast iron upper sleeve cover 2.1；
The vertical heat-exchange tube of other groups is separately fixed on upper and lower power board by the way of welding up and down.
Cast iron upper sleeve cover 2.1 is movable part, and cross section is circle, and up big and down small, lower diameter on upper power board 1.1 than being opened
If the small 0.5mm of bore dia, fixed, several castings in the hole opened up on the upper power board 1.1 of the lower end of cast iron upper sleeve cover 2.1 insertion
Refractory cement sealing is poured between iron upper sleeve cover 2.1.
Replaceable pipe position is temperature highest position in whole heat exchanger, and its life-span determines the longevity of whole exchanger
Life, if breakage occurs for replaceable pipe, upper power board above fire clay can be removed, cast iron upper sleeve cover is taken out, replaceable pipe obtains
Mobile space, from 1.3 position of median septum, one one is completely drawn out, similarly from the position of median septum 1.3 by new replaceable pipe
Power board 1.1 is upward through, is inserted still further below in straight-through sleeve pipe 2.2, after all replaceable pipes are changed, in upper power board
All cast iron upper sleeve covers 2.1, fixed replaceable pipe are put on 1.1, then pours refractory cement again and completes sealing.
To coordinate exchanger heat exchange area size, vertical heat exchanger group can be 2 groups, or 4 groups of even more more, flues
A3.1, flue B3.2, flue C3.3, lower elbow A4.1, lower elbow B4.2 also should accordingly increase and decrease.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
