The high-temperature fluid extrudes the stamping ring 723 from inside to outside, so that the extrusion pad 722 is pushed by the stamping ring 723, the stamping ring 723 slides on the surface of the outer ring 721 to extrude the bending elastic sheet 725, the sliding block 727 is extruded by the bending elastic sheet 725 to slide on the surface of the limiting ring 726, and along with the high-temperature fluid in the circulation cell 73 being conveyed into the shell 13, the pressure applied to the inner wall of the circulation cell 73 is changed, so that the pushing ring column 72 is in a moving state.
The surface sliding connection of snap ring 728 has punching press ring 723, and the surface sliding connection of punching press ring 723 has the extrusion pad 722, and extrusion pad 722 extrudees the adaptation with buckling shrapnel 725. Because snap ring 728 is connected at the inner wall of circulation cell 73 for circulation cell 73 is driven by the extrusion ring post 72 and is in tensile state, make the concave pipe of both sides receive the tensile influence of circulation cell 73 can change with spacing bead 75 between the laminating position, avoid spacing bead 75 to block up the concave pipe, high temperature fluid is difficult to circulate, and the impurity and the deposit adhesion on circulation cell 73 surface that can avoid filtering out are produced to the tensile ability of circulation cell 73 shape simultaneously, are difficult to clear up.
When the heat exchange device is used, a worker conveys the cold medium fluid into the heat transfer tube 8 through the cold medium inlet 3, and conveys the heat medium fluid into the shell 13 through the heat medium inlet 2, and after the heat medium fluid enters the shell 13, the heat medium fluid and the low-temperature fluid respectively flow in the shell 13 and the heat transfer tube 8 along with the high-temperature fluid and the low-temperature fluid, and heat exchange is completed through heat exchange.
The heat exchanger is used for exchanging heat between the oil or solvent of the high-temperature liquid phase and the low-temperature fluid, so that the high-temperature fluid is cooled, and because precipitation or flocculent impurities are easy to generate in the oil or solvent of the high-temperature liquid phase, the high-temperature fluid is conveyed into the flow cell 73 through the injection port 74 before conveying, is discharged through the discharge port 78, and the precipitate and the impurities are filtered and deposited in the flow cell 73, so that the high-temperature fluid is filtered.
Because the surfaces of the injection port 74 and the discharge port 78 are respectively provided with the first concave pipe 76 and the second concave pipe 77, and the first concave pipe 76 and the second concave pipe 77 are oppositely arranged, the limiting rotating beads 75 are clamped between the two concave pipes, the top ends of the concave pipes are made of elastic materials, when high-temperature fluid flows into the circulation bag 73 through the injection port 74, the limiting rotating beads 75 are pushed by the impact force generated by the high-temperature fluid to rotate between the two concave pipes, the flow rate of the high-temperature fluid is reduced, and the breakage of the heat transfer pipe 8 caused by the fact that the flow rate of the high-temperature fluid is too fast and the temperature difference of the two fluids is large is avoided.
The spacing commentaries on classics pearl 75 is promoted by high temperature fluid and produces the rotation, can control the speed that high temperature fluid flows in from the concave pipe, when the velocity of flow is too fast, because the tip of concave pipe is elastic material, spacing commentaries on classics pearl 75 is promoted by high temperature fluid and the surface formation extrusion of second concave pipe 77, the clearance between the spacing commentaries on classics pearl 75 diminishes with the deformation of second concave pipe 77 production to influence the outflow speed of high temperature fluid, the radian of spacing commentaries on classics pearl 75 and both sides concave pipe is not adapted, can not form sealing state between spacing commentaries on classics pearl 75 and the concave pipe, avoid causing concave pipe jam.
After the high-temperature fluid is injected into the flow cell 73, as the aperture of the discharge port 78 is smaller, and the flow cell 73 is spherical, sediment and flocculent impurities in the high-temperature fluid are blocked by the limiting rotating beads 75 and deposited in the flow cell 73; since the high-temperature fluid is collected in the flow cell 73, the inner wall of the flow cell 73 is extruded, so that the pushing ring columns 72 on two sides are extruded to deform.
The high-temperature fluid extrudes the stamping ring 723 from inside to outside, so that the extrusion pad 722 is pushed by the stamping ring 723, the stamping ring 723 slides on the surface of the outer ring 721 to extrude the bending elastic sheet 725, the sliding block 727 is extruded by the bending elastic sheet 725 to slide on the surface of the limiting ring 726, and along with the high-temperature fluid in the circulation cell 73 being conveyed into the shell 13, the pressure applied to the inner wall of the circulation cell 73 is changed, so that the pushing ring column 72 is in a moving state.
Because snap ring 728 is connected at the inner wall of circulation cell 73 for circulation cell 73 is driven by the extrusion ring post 72 and is in tensile state, make the concave pipe of both sides receive the tensile influence of circulation cell 73 can change with spacing bead 75 between the laminating position, avoid spacing bead 75 to block up the concave pipe, high temperature fluid is difficult to circulate, and the impurity and the deposit adhesion on circulation cell 73 surface that can avoid filtering out are produced to the tensile ability of circulation cell 73 shape simultaneously, are difficult to clear up.
Since the cleaning slider 93 is made of a floating material, the cleaning slider 93 floats upward on the surface of the slide shaft 94 as the high-temperature liquid in the housing 13 rises, and the surface of the heat transfer pipe 8 is cleaned.
The high-temperature fluid flows into the shell 13 to push the heat transfer tube 8 and the second folded plate 91 arranged on the surface of the supporting rod 11, the supporting rod 11 is of a damping structure, and after the second folded plate 91 is pushed to the position of the fixed tube plate 10, the supporting rod 11 rebounds, so that the second folded plate 91 is reset, and the heat transfer tube 8 is convenient to clean for a plurality of times.
The sliding frame 932 is affected by the water level of the high-temperature fluid in the casing 13, slides on the surface of the sliding shaft 94, and because the arrangement angle of the heat transfer tubes 8 is complex, the sliding frame 932 rubs the friction pad 934 with the heat transfer tubes 8 during sliding, and extrudes the extrusion folded pieces 935 according to the positions of the heat transfer tubes 8, so that the multi-angle cleaning effect of the heat transfer tubes 8 is achieved.
