Detailed description of the invention
The utility model proposes a kind of fixed structure for nonmetallic heat exchanger, in order to make advantage of the present utility model, technical scheme clearly, clearly, below in conjunction with specific embodiment, the utility model being elaborated.
The utility model, for the fixed structure of nonmetallic heat exchanger, as shown in Figure 1, comprise top tie plate 2, intermediate connector 3, lower seal plate 4, flexible shroud pipe 5 and metallic pin 6, top tie plate 2 and lower seal plate 4 arranged in parallel, therebetween certain vertical range is kept, intermediate connector 3 is positioned at the end of top tie plate 2 and lower seal plate 4, top tie plate 2 and lower seal plate 4 are fixed by it, fixed form can be connected by bolt or welding manner, top tie plate 2, namely region between intermediate connector 3 and lower seal plate forms a buffering area.
Top tie plate 2 being provided with through hole one, for placing heat exchanger tube 1 in through hole one, lower seal plate 4 being provided with through hole two, through hole one and through hole two position are oppositely arranged, the two point-blank, heat exchanger tube penetrates by bottom through hole two, passes from through hole one upper end.
Be positioned at the heat exchanger tube at top tie plate 2 place, fix by various ways, as first kind of way, heat exchanger tube is embedded in metallic pin 6, top tie plate 2 can adopt metal material, also non-metallic material can be adopted, the aperture of the through hole one on top tie plate 2 is slightly less than heat exchanger tube external diameter, heat exchanger tube is through behind this hole, metallic pin is embedded in heat exchanger tube inside, realize the expanded joint between three, metallic pin has certain anti-corrosion capability, there is flow-guiding channel metallic pin inside, flange process is carried out at top, not easily come off from installing hole, metallic pin any surface finish, without sharp edges, the second way, top tie plate adopts non-metallic material, through hole one aperture of top tie plate is slightly less than heat exchanger tube external diameter, heat exchanger tube is through behind this hole, hot gas welding or other solder technology is utilized to make it combine to both weldings, or increase a kind of material being beneficial to both and welding together between, three's welding realizes firmly connecting.
Be positioned at the heat exchanger tube of lower seal plate 4, flexible shroud pipe is embedded with between this heat exchanger tube and through hole two, lower seal plate is corrosion resistant metal material, can be single material, also can be composite, guarantee plate surface impulse-free robustness, without sharp edges, sealing plate bottom and hot side contacts position all need to carry out preservative treatment, the lower edges of through hole two needs chamfered to prevent the sheath that weares and teares, and open pore size is slightly less than the external diameter of flexible sealing sheath; As shown in Figure 5, the length of flexible shroud pipe 5 and the thickness of lower seal plate match, external diameter is slightly larger than the aperture of lower seal plate, internal diameter is slightly less than the external diameter of heat exchanger tube, make to form interference fit between three, tube wall need have certain thickness and not easily be worn, and flexible shroud need have the features such as high-and low-temperature resistance burn into is ageing-resistant.
According to above-mentioned heat exchanger tube and through hole one, the connected mode of flexible shroud pipe and through hole two, can be combined to multiple situation, as Fig. 1, the heat exchanger tube at top tie plate place, realize expanded joint by metallic pin between itself and through hole one, the heat exchanger tube in lower seal plate 4 and the flexible shroud pipe between through hole two, top and bottom do not have flange; As shown in Figure 2, be that all there is flange the heat exchanger tube in lower seal plate 4 and the flexible shroud pipe top between through hole two and bottom, better prevent heat exchanger tube from moving up and down with Fig. 1 difference.
As shown in Figure 3, the heat exchanger tube at top tie plate place, logically between its with through hole one to weld or alternate manner is connected, the heat exchanger tube in lower seal plate 4 and the flexible shroud pipe between through hole two, and top and bottom do not have flange; As shown in Figure 4, be that the heat exchanger tube in lower seal plate 4 and the flexible shroud pipe top between through hole two and bottom are provided with flange with Fig. 3 difference.Above-mentioned flexible shroud pipe not easily comes off from upper and lower after loading lower seal plate, and flexible shroud pipe need have the features such as high-and low-temperature resistance burn into is ageing-resistant.
The cardinal principle fixing means of above-mentioned fixed structure, comprises the following steps:
Top tie plate and lower seal plate are fixed by intermediate connector, through hole one and through hole two are set at the correspondence position of top tie plate and lower tie plate;
Through hole two place is sheathed good flexible shroud pipe first, heat exchanger tube flows slowly over lower tie plate from lower to upper from through hole two, after enter buffering area, heat exchanger tube continues from the lower end of through hole one slowly through upper end, through rear reserved certain length, heat exchanger tube is herein fixed by expanded joint or alternate manner.
It should be noted that, those skilled in the art under enlightenment of the present utility model, by simply replacing the technical scheme that obtains all within protection domain of the present utility model.
