Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a spiral plate heat exchanger. Background Technology

[0002] Spiral plate heat exchangers are highly efficient heat exchange devices, commonly used for heat transfer between liquids or gases. They consist of a series of spiral metal plates stacked together with certain gaps to form a spiral channel. Due to the spiral plate design, spiral plate heat exchangers are relatively small in size and occupy little space, making them widely used in chemical, petroleum, pharmaceutical, and food industries for heat transfer processes such as heating, cooling, and evaporation. However, current spiral plate heat exchangers still have the following shortcomings:

[0003] For example, patent document CN221302045U discloses a spiral plate heat exchanger. This spiral plate heat exchanger has a simple manufacturing process, the grooves are not easily damaged, and less material is used in its manufacture. Moreover, the density of the elongated oval grooves arranged in a triangular pattern can be set to be relatively dense, which makes the spiral plate heat exchanger have good stress distribution. However, its sealing and heat insulation performance is poor, which can easily lead to a decrease in internal heat exchange efficiency.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a spiral plate heat exchanger. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral plate heat exchanger, comprising a heat exchanger tank and a protective assembly. A fixed support frame is installed on the lower side of the heat exchanger tank, and a fixed base plate is provided at the bottom of the fixed support frame. A first inlet pipe is installed on the rear side of the heat exchanger tank, and a first outlet pipe is provided at the lower right end of the heat exchanger tank. A second outlet pipe is installed at the upper left end of the heat exchanger tank. The protective assembly is disposed on the surface of the heat exchanger tank and includes an insulation cavity, insulation cotton, an annular snap-fit ​​groove, a snap-fit ​​ring, a sealing tank cover, and an inner support rod. The insulation cavity is opened inside the tank wall of the heat exchanger tank and is filled with insulation cotton. An annular snap-fit ​​groove is opened on the front surface of the heat exchanger tank.

[0007] Furthermore, a snap-fit ​​ring is engaged with the inner side of the annular snap-fit ​​groove, and the front surface of the snap-fit ​​ring is disposed on the sealing can cover.

[0008] Furthermore, an inner support rod is provided inside the sealed tank cover and the rear side of the heat exchanger tank, and the rear surface of the sealed tank cover is connected to the front surface of the heat exchanger tank.

[0009] Furthermore, the sealing can cover is made of hard steel, and a second inlet pipe is provided on the front surface of the sealing can cover.

[0010] Furthermore, a fixing plate is installed on the rear end of the upper surface of the fixing base plate, and the surface of the fixing plate is provided with an active component for automatic can opening.

[0011] Furthermore, the movable component includes a servo motor, a threaded screw, an auxiliary moving cylinder, a limiting groove, and a limiting slide rod. The servo motor is located on the rear surface of the fixed plate. The output end of the servo motor is connected to the threaded screw via a coupling. The auxiliary moving cylinder is threadedly connected to the outer surface of the threaded screw. A limiting groove is formed on the upper surface of the fixed base plate, and a limiting slide rod is slidably connected to the inner side of the limiting groove. The upper end of the limiting slide rod is connected to the rear surface of the auxiliary moving cylinder.

[0012] Furthermore, the movable component also includes a fixed base, casters, and a movable support frame. The fixed base is installed on the front surface of the auxiliary movable cylinder, the casters are installed on the lower side of the fixed base, and the movable support frame is provided on the upper side of the fixed base. The inner side of the upper end of the movable support frame is connected to the lower surface of the sealed can lid.

[0013] Furthermore, both the fixed support frame and the movable support frame have threaded connections to their upper surfaces, and the fixed bolts are symmetrically arranged on both sides of the upper ends of the fixed support frame and the movable support frame. The heat exchanger tank is equipped with a spiral heat exchange plate, and the front side of the spiral heat exchange plate is connected to the rear inner surface of the sealed tank cover.

[0014] This utility model provides a spiral plate heat exchanger, which has the following beneficial effects:

[0015] 1. This utility model incorporates a protective component, which includes an insulation cavity, insulation cotton, an annular snap-fit ​​groove, a snap-fit ​​ring, a sealing lid, and an inner support rod. In use, the sealing lid is installed on the heat exchanger tank by engaging the snap-fit ​​ring with the inner side of the annular snap-fit ​​groove, thus strengthening the seal of the sealing lid on the heat exchanger tank. The insulation cavity provides heat insulation and noise reduction for the heat exchanger tank. The insulation cotton further enhances the heat insulation effect on the heat exchanger tank.

[0016] 2. This utility model incorporates a movable component, including a servo motor, a threaded screw, an auxiliary moving cylinder, a limiting groove, and a limiting slide rod. The movable component also includes a fixed base, casters, and a movable support frame. In use, the servo motor is activated, causing the threaded screw to rotate. This causes the threaded screw to move the auxiliary moving cylinder along the surface of the threaded screw. The lower end of the limiting slide rod slides into the inner side of the limiting groove, limiting the movement of the auxiliary moving cylinder. The movement of the auxiliary moving cylinder causes the fixed base to move forward via the casters, which in turn moves the movable support frame. This, in turn, moves the sealing tank cover, causing the spiral heat exchange plate to move out of the heat exchanger tank. This allows the device to automatically open the tank after heat exchange, preventing operators from being burned by contact with the heat exchanger tank and facilitating maintenance or cleaning of the internal structure of the heat exchanger tank.

[0024] The specific operation is as follows: During use, the sealing tank cover 705 is installed on the heat exchanger tank 1 by engaging the snap ring 704 with the inner side of the annular snap groove 703, thereby strengthening the sealing of the heat exchanger tank 1 by the sealing tank cover 705. The heat insulation cavity 701 can provide heat insulation and noise reduction for the heat exchanger tank 1. The heat insulation cotton 702 can further improve the heat insulation effect of the heat exchanger tank 1. The inner support rod 706 can improve the support and stability of the heat exchanger tank 1 and the sealing tank cover 705.

[0025] Please refer to Figures 1 to 3A snap-fit ​​ring 704 is engaged with the inner side of the annular snap-fit ​​groove 703, and the front surface of the snap-fit ​​ring 704 is set on the sealing tank cover 705. An inner support rod 706 is set inside the sealing tank cover 705 and the rear side of the heat exchanger tank 1. The rear surface of the sealing tank cover 705 is connected to the front surface of the heat exchanger tank 1. The sealing tank cover 705 is a rigid steel structure, and a second inlet pipe 8 is set on the front surface of the sealing tank cover 705.

Furthermore, the surface of the fixed plate 9 is provided with an active component 10 for automatic can opening. The active component 10 includes a servo motor 1001, a threaded screw 1002, an auxiliary moving cylinder 1003, a limiting slide groove 1004, and a limiting slide rod 1005. The servo motor 1001 is located on the rear surface of the fixed plate 9. The output end of the servo motor 1001 is connected to the threaded screw 1002 via a coupling. The auxiliary moving cylinder 1003 is threadedly connected to the outer surface of the threaded screw 1002. The fixed bottom... A limiting groove 1004 is formed on the upper surface of plate 3, and a limiting rod 1005 is slidably connected to the inner side of the limiting groove 1004. The upper end of the limiting rod 1005 is connected to the rear end surface of the auxiliary moving cylinder 1003. The movable component 10 also includes a fixed seat 1006, a caster wheel 1007, and a movable support frame 1008.

The insulation cavity 701 provides heat insulation and noise reduction for the heat exchanger tank 1, and the insulation cotton 702 further enhances the heat insulation effect of the heat exchanger tank 1. The inner support rod 706 improves the support and stability of the heat exchanger tank 1 and the sealing tank cover 705. Subsequently, the servo motor 1001 is started, causing the servo motor 1001 to... The screw 1002 is rotated, causing the screw 1002 to move the auxiliary moving cylinder 1003 along the surface of the screw 1002. The movement of the auxiliary moving cylinder 1003 is limited by the sliding connection between the lower end of the limiting slide rod 1005 and the inner side of the limiting slide groove 1004. The movement of the auxiliary moving cylinder 1003 causes the fixed seat 1006 to move forward through the universal wheel 1007. The fixed seat 1006 then moves the movable support frame 1008, which in turn moves the sealing tank cover 705, causing the spiral heat exchange plate 12 to move out of the inner side of the heat exchanger tank 1.
