Description
Technical field
The utility model relates to the heater that a kind of use conduction oil that is widely used in fields such as printing and dyeing, chemical industry, food heats various liquid.
Background technology
In existing technology, oil adds heat exchanger and all adopts stainless steel calandria arranged side by side, and because of conduction oil, oil temperature is high, reach 280 ~ 300 ℃, the coefficient difference of expanding with heat and contract with cold of stainless steel tube.So the hot swollen shrinkage between stainless steel pipe and the pipe is different, therefore produce in the middle of the stainless steel pipe fracture and weld weld seam and take off and split, the danger that the high temperature heat conductive oil leakage causes serious accident takes place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and makes every stainless steel heat exchanger tube all freely stretch, solve because of the different safe and reliable more oily heating heat exchangers of the oily heating heat exchanger that breaks, makes operation that cause of the hot swollen shrinkage coefficient of oil temperature height, heat exchanger tube.
The technical scheme that provides according to the utility model, described oily heating heat exchanger, comprise cylindrical shell, end socket, back cover and heat conductive oil inlet flange, the conduction oil outlet(discharge) flange, water inlet flange and delivery port flange, one end of cylindrical shell is welded with end socket, the other end of cylindrical shell is welded with back cover, in cylindrical shell, be installed with tube sheet, offer tube sheet water inlet and tube sheet delivery port on the tube sheet, on tube sheet, be installed with first heat exchanger tube and second heat exchanger tube, first heat exchanger tube and second heat exchanger tube are set in parallel, the first heat exchanger tube end away from tube sheet links to each other by bend pipe with the second heat exchanger tube end, first heat exchanger tube is communicated with by the tube sheet delivery port with the delivery port flange, second heat exchanger tube is communicated with by the tube sheet water inlet with the water inlet flange, on tube sheet, be fixedly connected with dividing plate, the other end of dividing plate is connected on the cylindrical shell, and described dividing plate separates water inlet and delivery port.
On tube sheet, be fixedly connected with some deflection plate pull bars, on every deflection plate pull bar, all be installed with a deflection plate, the axis of every deflection plate and cylindrical shell all is set in parallel, and adjacent two deflection plates are set in parallel, and adjacent two deflection plates are on short transverse and shift to install.
Every stainless steel tube heat exchanger tube in the utility model can freely stretch, and has solved because of different the breaking of causing of the hot swollen shrinkage coefficient of oil temperature height, heat exchanger tube, makes the oily heating heat exchanger of operation safer, reliable.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly is made of with parts such as heat conductive oil inlet flange 4, conduction oil outlet(discharge) flange 5, water inlet flange 6, delivery port flange 7, tube sheet 8, tube sheet water inlet 8.1, tube sheet delivery port 8.2, first heat exchanger tube 9.1, second heat exchanger tube 9.2, bend pipe 9.3, dividing plate 10, deflection plate pull bar 11 and deflection plates 12 cylindrical shell 1, end socket 2, back cover 3.
This oil heating heat exchanger, comprise cylindrical shell 1, end socket 2, back cover 3 and heat conductive oil inlet flange 4, conduction oil outlet(discharge) flange 5, water inlet flange 6 and delivery port flange 7, one end of cylindrical shell 1 is welded with end socket 2, the other end of cylindrical shell 1 is welded with back cover 3, in cylindrical shell 1, be installed with tube sheet 8, offer tube sheet water inlet 8.1 and tube sheet delivery port 8.2 on the tube sheet 8, on tube sheet 8, be installed with first heat exchanger tube 9.1 and second heat exchanger tube 9.2, first heat exchanger tube 9.1 and second heat exchanger tube 9.2 are set in parallel, first heat exchanger tube, 9.1 ends away from tube sheet 8 link to each other by bend pipe 9.3 with second heat exchanger tube, 9.2 ends, first heat exchanger tube 9.1 is communicated with by tube sheet delivery port 8.2 with delivery port flange 7, second heat exchanger tube 9.2 is communicated with by tube sheet water inlet 8.1 with water inlet flange 6, on tube sheet 8, be fixedly connected with dividing plate 10, the other end of dividing plate 10 is connected on the cylindrical shell 1, and described dividing plate 10 separates water inlet and delivery port.
On tube sheet 8, be fixedly connected with some deflection plate pull bars 11, on every deflection plate pull bar 11, all be installed with a deflection plate 12, every deflection plate 12 all is set in parallel with the axis of cylindrical shell 1, adjacent two deflection plates 12 are set in parallel, and adjacent two deflection plates 12 are on short transverse and shift to install.
The utility model is welded on end socket 2, back cover 3 on the cylindrical shell 1 earlier, dividing plate 10, tube sheet 8 are welded on the component of cylindrical shell 1, end socket 2 and back cover 3, give component every shunting in forming one, first heat exchanger tube 9.1, second heat exchanger tube 9.2 form U type heat exchanger tubes with bend pipe 9.3, and this heat exchanger tube is on tube sheet 8 and weld reliably.After cylindrical shell 1 and end socket 2, back cover 3 welding, be enclosed within on the U type heat exchanger tube, and weld formation cylindrical shell sub-assembly with tube sheet 8.The cylindrical shell sub-assembly connects into an oil heater with the shunting conjunction by screw, nut again.
