Fixed tube sheet 3, can be fixed on one end of housing 1, and cause the junction of fixed tube sheet 3 and housing 1 by second flange 12
Sealing is formed, so that medium (water, air) leakage will not occur in the junction of housing 1 and fixed tube sheet 3.
As shown in Figure 1 and Figure 4, the left end of the bobbin carriage 5 at floating tube sheet 4 is provided with (the 3rd flange of the 3rd flange 52
52 are close to the left end of bobbin carriage 5, and the diameter of the 3rd flange 52 is slightly larger than the diameter of bobbin carriage 5), the right-hand member of housing 1 is provided with the 4th
Flange 13, as can be seen that floating tube sheet 4 is located at the 3rd flange 52 and the junction of the 4th flange 13 is attached from Fig. 1 and in Fig. 4
Closely, and due to floating tube sheet 4 be located at housing 1 cavity in and floating tube sheet 4 can be moved along the cavity of housing 1 so that
In order that the junction for obtaining housing 1 and floating tube sheet 4 forms sealing structure, can be between the 3rd flange 52 and the 4th flange 13
Filler 6 is set, and the width of filler 6 is more than the displacement that floating tube sheet 4 is expanded with heat and contract with cold and occurred, that is to say, that floating tube sheet
The low order end of 4 (floating tube sheet 4 has certain thickness) will not leave the low order end of filler 6 in the case where expanding with heat and contract with cold, activity
The high order end of tube sheet 4 will not leave the high order end of filler 6 in the case where expanding with heat and contract with cold, so as to form opposing seal
Structure, medium (water, air) leakage will not occur in the junction of housing 1 and floating tube sheet 4.
As shown in figure 4, provided with a circle becket 7 between the flange 13 of filler 6 and the 4th, becket 7 is used for against filler
6。
As depicted in figs. 1 and 2, heat exchange core body 2 includes heat exchanger tube 22 and pull bar 23, and heat exchanger tube 22 passes through connecting rod and pull bar
23 are connected.Multiple heat exchanger tubes 22 can be connected by pull bar 23.
As shown in figure 1, housing 1, which is provided with, forms air inlet and the saddle 14 of gas outlet.
As shown in figure 1, in the present embodiment, housing 1 is overall preferably in cylinder.The overall housing 1 in cylinder more holds
Easily it is made and later maintenance.
In the utility model, because one end of heat exchange core body 2 is fixed tube sheet 3, the other end is floating tube sheet 4, therefore,
When the larger operating mode of the temperature difference is run into during use, heat exchange core body 2 can expand with heat and contract with cold, and due to the presence of floating tube sheet 4, then
Axial direction of the core body along housing 1 can be caused to move, so that heat exchange core body 2 will not be extruded between housing 1, will not
Larger tension is produced, heat exchange core body 2 will not be damaged, simultaneously as floating tube sheet of the present utility model 4 can be in housing
Moved in 1, when needing cleaning heat exchanger, it is only necessary to pull down fixed tube sheet 3 and floating tube sheet 4, pull fixed tube sheet 3,
Heat exchange core body 2 is extracted out from the left end of housing 1, cavity and heat exchange core body 2 then again to housing 1 are cleaned, therefore, side
Just overall cleaning.
