Splicing position at input straight tube and output straight tube is provided with O-ring seal.
On the floating coiled pipe assembly, be provided with bolt, on last clamping plate, following clamping plate and heat exchanger tube dish, be provided with the locating hole that matches with bolt.
The shell side import tangentially is provided with along the inner walls circumference.
Bottom at low head is provided with sewage draining exit.
Last clamping plate and following clamping plate are circular clamping plate, have a plurality of media and pass through the aperture on clamping plate.
Improve as another kind of the present invention:
The input straight tube of each heat exchanger tube dish and output straight tube are provided with connecting thread by being threaded on the mouth of pipe of input straight tube and output straight tube, the input straight tube is connected with the output straight tube with the input straight tube of adjacent tubes dish by the pipe fitting that is threaded with the output straight tube.
Beneficial effect: removable floating coiler heat exhanger of the present invention, owing to adopted the technical characterictic of the formation floating coiled pipe assembly that will a plurality of independently heat exchanger tube dishes be serially connected, make that removable floating coiler heat exhanger of the present invention can be by increasing or reduce the quantity of heat exchanger tube dish, realization is convenient as plate type heat exchanger, adjust heat exchange area quickly, make heat exchanger can adapt to different needs of work, and in the course of the work, when indivedual heat exchanger tube adjustment debits are badly revealed, can remove easily and more renew the heat exchanger tube dish fast, it is non-exchange to have overcome heat exchanger tube of the prior art, reveal the drawback that just can only take the blocking way processing and sacrifice heat exchange area in case be damaged, when heat exchange area is adjusted in the needs increase and decrease, only need open the clamping plate bolt, increasing or reduce the heat exchanger tube dish gets final product, simultaneously, adopt a plurality of independently heat exchanger tube dishes to be serially connected to constitute coil pack and make the production of removable floating coiler heat exhanger of the present invention more convenient, the heat exchanger tube dish is carried out streamlined production as a kind of standard heat exchange element, concrete heat exchange requires to determine to constitute the heat exchanger tube dish number of floating coiled pipe assembly according to different user, be assembled into needed floating coiler heat exhanger fast, improved production efficiency, shorten production man-hour, reduced production cost; Owing to adopted the input straight tube and the socket connection of output straight tube of each heat exchanger tube dish, the mouth of pipe at input straight tube and output straight tube two ends is made respectively to peg graft and is cooperated the technical characterictic of the mouth of pipe, makes the floating coiled pipe assembly assembling of removable floating coiler heat exhanger of the present invention convenient, quick; Owing to adopted the technical characterictic that is provided with O-ring seal at the splicing position of input straight tube and output straight tube, improved the sealing effectiveness of pegging graft; Owing to adopted on the floating coiled pipe assembly and be provided with bolt, on last clamping plate, following clamping plate and heat exchanger tube dish, be provided with the technical characterictic of the locating hole that matches with bolt, each the heat exchanger tube dish that constitutes the floating coiled pipe assembly can be located fast, be assembled into the floating coiled pipe assembly, also improved simultaneously the mechanical strength of floating coiled pipe assembly, made removable floating coiler heat exhanger work of the present invention more stable; Owing to adopted the shell side import along the tangential technical characterictic that is provided with of inner walls circumference, make heat transferring medium in housing, form eddy flow, fully contact with spiral heat exchange tube, the heat exchange better effects if, simultaneously heat transferring medium is in housing during eddy flow, the granule foreign of being carried secretly can revolve and fall at housing bottom, and the sewage draining exit of the bottom by low head in time discharges, and removable floating coiler heat exhanger of the present invention has been possessed from decontamination function; Because having adopted last clamping plate and following clamping plate is circular clamping plate, on clamping plate, have the technical characterictic of a plurality of media by the aperture, make the production of clamping plate more convenient, and reduced the resistance of clamping plate, heat transferring medium can fully be contacted with spiral heat exchange tube heat transferring medium in the housing; Owing to adopted the input straight tube of each heat exchanger tube dish and exported straight tube by being threaded, on the mouth of pipe of input straight tube and output straight tube, be provided with connecting thread, input straight tube and the output straight tube input straight tube by be threaded pipe fitting and adjacent tubes dish with export the technical characterictic that straight tube is connected, further improved the bonding strength of each heat exchanger tube dish, made heat exchanger work more stable, reliable.
The specific embodiment
As shown in Figure 1, removable floating coiler heat exhanger of the present invention, comprise housing 2, on housing, have shell side import 9, shell side outlet 1, the shell side import tangentially is provided with along the inner walls circumference, is provided with floating coiled pipe assembly 6 in housing, and the tube side input pipe 11 and the tube side efferent duct 10 of floating coiled pipe assembly extend housing through housing low head 12, the housing low head is connected with housing by adpting flange, is provided with sewage draining exit 13 in the bottom of low head.Described coil pack comprises clamping plate 4, following clamping plate 8, is provided with a plurality of heat exchanger tube dishes 7 that are serially connected between last clamping plate and following clamping plate.As Fig. 2, shown in Figure 3, described heat exchanger tube dish is made of input straight tube 71, output straight tube 72 and spiral heat exchange tube 73, spiral heat exchange tube UNICOM input straight tube and output straight tube.As shown in Figure 4, the input straight tube of each heat exchanger tube dish and output straight tube are serially connected by inserting mode, and the input straight tube is made respectively to peg graft with the mouth of pipe of exporting the straight tube two ends and cooperated the mouth of pipe, is provided with O-ring seal 75 at input straight tube and the splicing position of exporting straight tube.The input straight tube of each pipe dish is connected in series back connection tube side input pipe in turn, and the output straight tube of each pipe dish is connected in series the back in turn and connects the tube side efferent duct, and the input straight tube that is positioned at the heat exchanger tube dish of the superiors is done the shutoff processing with the upper orifice of output straight tube.As shown in Figure 5, last clamping plate and following clamping plate are circular clamping plate, have a plurality of media by aperture 41 on clamping plate.Last clamping plate and following clamping plate are provided with bolt 3 by fishbolt 5 tensions on coil pack, be provided with the locating hole 74 that matches with bolt on the heat exchanger tube dish, also are provided with the locating hole that matches with bolt on last clamping plate, following clamping plate.
As another embodiment of the invention:
The input straight tube of each heat exchanger tube dish and output straight tube are established connecting thread by being threaded on the mouth of pipe of input straight tube and output straight tube, the input straight tube is connected with the output straight tube with the input straight tube of adjacent tubes dish by the pipe fitting that is threaded with the output straight tube.
