DETAILED DESCRIPTION
[0019] In order to enable personnel in the technical field to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
[0020] Combining Figure 1 The utility model discloses a quick -washed graphite heat exchanger, including heat exchange part 1, heat exchange part 1 is equipped with opposite first end and second end, and the first end and the second end of heat exchange part 1 are detachably encapsulated with first head 2 and second head 3 respectively, first head 2 still is fixed with first cover plate 4, and the both sides of cover plate extend outward with extension plate 5, and the first end and the second end of heat exchange part 1 are fixed with first sleeve ring and second sleeve ring respectively, and extension plate 5 and first sleeve ring are set up with corresponding first screw hole respectively, and extension plate 5 and first sleeve ring are connected through first screw hole and first stud 6.
[0021] When actually using, first stud 6 is taken out from first screw hole, then first cover plate 4 and first head 2 are unloaded in proper order, and heat exchange part 1 can be cleaned, and can be quickly reloaded after cleaning.
[0022] Second head 3 is fixed with second cover plate 8, and the both sides of second cover plate 8 extend outward with boss 9, and extension plate 5 and second sleeve ring are set up with corresponding second screw hole respectively, and boss 9 and second sleeve ring are connected through second screw hole and second stud 10.
[0023] The second end of heat exchange part 1 is similar to the first end, when needing cleaning, second stud 10 is unloaded in second screw hole, and second cover plate 8 and second head 3 are unloaded in proper order.
[0024] Still include elastic compensator, and the elastic compensator includes:
[0025] Fixed seat 1101 is fixed on the lateral wall of heat exchange part 1;
[0026] Supporting rod is vertically installed on fixed seat 1101, and the first end of supporting rod is connected with fixed seat 1101;
[0027] Movable seat 1102 is installed on the second end of supporting rod;
[0028] Spring 1103 is connected with fixed seat 1101 and movable seat 1102 respectively.
[0029] Spring compensator 11 is used elastic deformation of spring 1103 to absorb or compensate the deformation difference in mechanical system, when the mechanical system produces deformation due to temperature change, material thermal expansion, loosening or wear, the spring 1103 in spring compensator 1103 will be elastically deformed accordingly, to offset or reduce the influence of deformation on the stability and precision of mechanical system.
[0030] It is worth mentioning that, in the operation temperature, due to the different linear expansion coefficients or temperatures of the graphite parts and the metal parts in the heat exchanger, the expansion amount is different, the spring 1103 can compensate, so that the graphite part is not subjected to excessive stress, and the necessary compression force for the gasket sealing is ensured. At the same time, it can also avoid the damage of the graphite part due to the excessive external force of the tightening bolt during the assembly of the equipment.
[0031] It is worth mentioning that the spring compensator 11 also has the function of adjusting the tension of the spring 1103, and for this, it should also include an adjusting nut, wherein the fixed seat and the support rod can be directly fixed together by welding, bolt connection or other mechanical connection methods, and the adjusting nut is usually connected with the fixed seat or the support rod by threads. This connection method allows the pre-tightening force and working height of the spring to be adjusted by rotating the adjusting nut, and the threaded connection has the advantages of simple structure, convenient adjustment and the like, and is a commonly used connection method in the spring compensation device; in some cases, in order to prevent the adjusting nut from loosening under vibration or load change, additional locking devices (such as locking nuts, locking pins, etc.) can be used to fix the position of the adjusting nut.
