Abstract
The utility model relates to a heat exchanger, in particular to a dual-head float tubular graphite heat exchanger which is provided with fixed tube plate, heat exchange tube, and also pull rod, cast iron press cover, metal shell flange, transition press plate and O-shaped sealing ring, the heat exchange tubes are arranged side by side and are fixed by the fixed tube plates at two ends, the transition press plate, the metal shell flange and the cast iron press cover are provided at the outer end of the fixed tube plate in order. The cast iron press cover, the metal shell flange, the transition press plate and the fixed tube plate are connected rigidly by the pull rods at two sides, the O-shaped sealing ring is arranged between the fixed tube plate and the transition press plate, the O-shaped sealing ring is sleeved at the heat exchange tube. The temperature of equipment has large application range, and the anti-impact and anti-vibration performance is improved greatly, detachable property is good, equipment maintenance is not limited by the location so as to prolong the using life and improve the application value of equipment.
Description
Technical field
The utility model relates to heat exchanger, especially a kind of double end tube-type graphite heat exchanger that floats.
Background technology
At present, the tube-type graphite heat exchanger that China produces, mainly by: parts such as upper and lower end socket, fixed tube sheet, floating tubesheet, heat exchanger tube, artificial flower plate and deflection plate are formed.Eliminating metal shell and restrain because of the different caused stress of the linear expansion coefficient of two kinds of unlike materials, is flexible under the effect that is subjected to temperature by floating tubesheet.Its shortcoming is the tube bank that can not eliminate whole equipment because of stress that factor produced such as temperature distributing disproportionation are even; Can not eliminate the stress that the linear expansion coefficient difference of unlike material between graphite tube plate, heat exchanger tube and the adhesive is produced.Serviceability temperature is relatively low, and impact resistance and freedom from vibration are relatively poor; Plant maintenance is cumbersome, have in addition because of the damage or the plugging of individual parts just causes whole equipment scrapping, even after the maintenance, its performance and service life also can be affected.
Summary of the invention
In order to overcome the deficiency of existing tube-type graphite heat exchanger, the purpose of this utility model provides the unsteady tube-type graphite heat exchanger of a kind of double end.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of double end tube-type graphite heat exchanger that floats, has fixed tube sheet, heat exchanger tube, also has pull bar, the cast iron gland, the metal shell flange, transition press plate, " O " RunddichtringO, pull-rod nut and spring, heat exchanger tube is arranged side by side and is fixed by the fixed tube sheet at two ends, the outer end of fixed tube sheet is disposed with transition press plate, metal shell flange and cast iron gland, and by the pull bar that is arranged on both sides and pull-rod nut with the cast iron gland, the metal shell flange, transition press plate forms rigidity with fixed tube sheet and is connected, be provided with " O " RunddichtringO between fixed tube sheet and transition press plate, " O " RunddichtringO is sleeved on the heat exchanger tube.
Further: between pull bar and pull-rod nut, be provided with spring.
Flexibly connect (sealing) with the formation of heat exchanger tube appearance behind " O " RunddichtringO pressurized, every heat exchanger tube can freely stretched between the fixed tube sheet at two ends under the effect of temperature, the interbank stress that is produced because of the linear expansion coefficient difference of unlike material between the stress that factor produced such as temperature distributing disproportionation is even and graphite tube plate and the heat exchanger tube of so just having eliminated whole equipment, thus the scope that whole device temperature uses also just strengthened.Again because tube sheet and interbankly do not have stress, so the impact resistance of whole equipment and freedom from vibration also are greatly improved.Adhesive is not used in the assembling of whole equipment, so the dismoutability of equipment is good, the releasing lever nut just can be changed parts aging or that damage, service equipment is not limited by or not the place, simultaneously can not influence the equipment serviceability yet, thereby can not cause scrapping of whole equipment to prolong the service life of equipment because of the damage or the plugging of individual parts, improved the use value of equipment, utilize spring to come to carrying out pressure compensation because of " O " RunddichtringO that follows the string after long-term the use, thereby guaranteed sealing, be applicable to temperature shock big (20 ℃-160 ℃), pressure (0.4Mpa), the Chemical Manufacture of the adaptable chemical corrosivity medium of impregnated graphite.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified;
Fig. 1 is a structural representation of the present utility model;
Among the figure 1, fixed tube sheet, 2, heat exchanger tube, 3, pull bar, 4, the cast iron gland, 5, the metal shell flange, 6, transition press plate, 7, " O " RunddichtringO, 8, pull-rod nut, 9, spring.
The specific embodiment
The tube-type graphite heat exchanger that floats of a kind of double end as shown in Figure 1, has fixed tube sheet 1, heat exchanger tube 2, also has pull bar 3, cast iron gland 4, metal shell flange 5, transition press plate 6, " O " RunddichtringO 7, pull-rod nut 8 and spring 9, heat exchanger tube 2 is arranged side by side and is fixing by the fixed tube sheet 1 at two ends, the outer end of fixed tube sheet 1 is disposed with transition press plate 6, metal shell flange 5 and cast iron gland 4, and by the pull bar 3 that is arranged on both sides and pull-rod nut 8 with cast iron gland 4, metal shell flange 5, transition press plate 6 forms rigidity with fixed tube sheet 1 and is connected, be provided with " O " RunddichtringO 7 between fixed tube sheet 1 and transition press plate 6, " O " RunddichtringO 7 is sleeved on the heat exchanger tube 2.Between pull bar 3 and pull-rod nut 8, be provided with spring 9, flexibly connect (sealing) with the formation of heat exchanger tube 2 appearances behind " O " RunddichtringO 7 pressurizeds, every heat exchanger tube 2 can freely be stretched at 1 of the fixed tube sheet at two ends under the effect of temperature, the interbank stress that is produced because of the linear expansion coefficient difference of unlike material between the stress that factor produced such as temperature distributing disproportionation is even and fixed tube sheet 1 and the heat exchanger tube 2 of so just having eliminated whole equipment, thus the scope that whole device temperature uses also just strengthened.Again because tube sheet and the interbank stress that do not exist, so the impact resistance and the freedom from vibration of whole equipment also are greatly improved, utilize spring to come because " O " RunddichtringO that follows the string after long-term the use carries out pressure compensation, thereby guaranteed sealing.
