Technical Field

[0001] This utility model relates to the field of spiral plate heat exchanger technology, specifically a spiral plate heat exchanger that is easy to operate and has stable temperature control. Background Technology

[0002] The spiral plate heat exchanger consists of two parallel metal plates rolled into concentric spiral channels, separated by a spacer column or baffle, forming two independent fluid channels. Cold and hot fluids are poured into these two channels respectively, flowing along the spiral path and exchanging heat through the metal plates. Temperature control of the spiral plate heat exchanger requires manipulating the opening and closing angles of the hot and cold inlet valves, thus changing the flow rates of the hot and cold media. However, due to the structural limitations of the spiral plate heat exchanger, the hot and cold inlet valves are installed far apart, making it difficult to quickly control the hot and cold inlet valves in traditional spiral plate heat exchangers, thereby reducing the ease of use of the device. To address these issues, a technological innovation is proposed based on the existing spiral plate heat exchanger. Utility Model Content

[0003] The purpose of this invention is to provide a spiral plate heat exchanger that is easy to operate and has stable temperature control, so as to solve the problems mentioned in the background art.

The first insulation pipe is located to the left of the cold medium inlet valve. Each of the handwheels of the hot and cold medium inlet valves has a set of anti-slip pads tightly fitted to its top. A pressure plate is provided on the top of the two sets of anti-slip pads. Two sets of guide rods are evenly arranged on the top of the pressure plate. A spring is placed on the outer ring of the guide rod. A threaded hole is opened on the top of the pressure plate, and a hand-tightening bolt is correspondingly located above the threaded hole.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3A spiral plate heat exchanger with convenient operation and stable temperature control includes a spiral plate heat exchanger 1. A first insulation pipe 2 is connected to the left side of the spiral plate heat exchanger 1. A hot medium inlet valve 21 is connected to the front side of the first insulation pipe 2. A third insulation pipe 3 is connected to the front side of the spiral plate heat exchanger 1. A cold medium inlet valve 31 is connected to the front side of the third insulation pipe 3. The first insulation pipe 2 is located to the left of the cold medium inlet valve 31. A set of anti-slip pads 46 is tightly fitted to the top of the handwheels of both the hot medium inlet valve 21 and the cold medium inlet valve 31. A pressure plate 45 is fixedly installed on the top of the two sets of anti-slip pads 46. Two sets of guide rods 44 are evenly fixedly installed on the top of the pressure plate 45. A spring 43 is placed on the outer ring of the guide rods 44. A threaded hole is opened on the top of the pressure plate 45. A hand-tightening bolt 41 is located above the threaded hole. A second insulation pipe 22 is connected to the front of the hot medium inlet valve 21, and a fourth insulation pipe 32 is connected to the front of the cold medium inlet valve 31. A hot medium drain pipe 23 is connected to the rear of the spiral plate heat exchanger 1, and a cold medium drain pipe 33 is connected to the right side of the spiral plate heat exchanger 1. Hot medium is introduced into the spiral plate heat exchanger 1 through the second insulation pipe 22, the hot medium inlet valve 21, and the first insulation pipe 2. Cold medium is introduced into the spiral plate heat exchanger 1 through the fourth insulation pipe 32, the cold medium inlet valve 31, and the third insulation pipe 3. This allows for heat exchange between the hot and cold media within the spiral plate heat exchanger 1. The hot medium is then discharged through the hot medium drain pipe 23, and the cold medium is discharged through the cold medium drain pipe 33. A support frame 11 is fixedly installed at the bottom of the spiral plate heat exchanger 1. A support plate 12 is fixedly installed at the front of the spiral plate heat exchanger 1. A reinforcing plate 13 is fixedly installed at the front of the support frame 11. The top of the reinforcing plate 13 is fixedly installed at the bottom of the support plate 12. The hot medium inlet valve 21 and the cold medium inlet valve 31 are both fixedly installed at the top of the support plate 12. A gantry frame 4 is fixedly installed at the top of the support plate 12. The gantry frame 4 is located outside the hot medium inlet valve 21 and the cold medium inlet valve 31. A first through hole is opened through the top of the gantry frame 4. A hand-tightening bolt 41 is rotatably installed in the first through hole. Two sets of second through holes are evenly opened through the top of the gantry frame 4. A pressure plate 45 is located inside the gantry frame 4. By moving the pressure plate 45 upward, the gantry frame 4 can be driven to move the heat exchanger. Two sets of anti-slip pads 46 are respectively separated from the handwheels of the hot medium inlet valve 21 and the cold medium inlet valve 31. When the pressure plate 45 contacts the hand-tightening bolt 41, the hand-tightening bolt 41 can be screwed into the threaded hole of the pressure plate 45 to fix the height of the pressure plate 45. Since the hot medium inlet valve 21 and the cold medium inlet valve 31 are close to each other, the workers can easily operate the hot medium inlet valve 21 and the cold medium inlet valve 31 to achieve the purpose of temperature control by changing the flow rate of hot and cold medium. The left and right sides of the pressure plate 45 are in contact with the left and right sides of the inner side wall of the gantry frame 4. The top of the guide rod 44 passes through the second through hole and is connected to the limit plate 42. The spring 43 is fixedly set between the limit plate 42 and the gantry frame 4.

[0015] Working principle: By moving the pressure plate 45 upward, the two sets of anti-slip pads 46 are respectively separated from the handwheels of the hot medium inlet valve 21 and the cold medium inlet valve 31. When the pressure plate 45 contacts the hand-tightening bolt 41, the hand-tightening bolt 41 can be screwed into the threaded hole of the pressure plate 45, thereby fixing the height of the pressure plate 45. Since the hot medium inlet valve 21 and the cold medium inlet valve 31 are located close to each other, it allows the operator to easily operate the hot medium inlet valve 21 and the cold medium inlet valve 31, thereby achieving the purpose of temperature control by changing the flow rate of the hot and cold medium. After the liquid inlet valve 31 is adjusted, the hand-tightened bolt 41 is separated from the pressure plate 45. At this time, the spring 43 uses its own rebound force to drive the pressure plate 45 to move downward and reset through the limit plate 42 and the guide rod 44. This causes the two sets of anti-slip pads 46 to fit tightly with the handwheels of the hot medium inlet valve 21 and the cold medium inlet valve 31, respectively, thereby locking the hot medium inlet valve 21 and the cold medium inlet valve 31 to ensure the stability of temperature control. It should be noted that when the spring 43 drives the pressure plate 45 to move downward, the worker needs to assist the pressure plate 45 to move downward to prevent the pressure plate 45 from falling quickly.

[0016] The hot medium is fed into the spiral plate heat exchanger 1 through the second insulation pipe 22, the hot medium inlet valve 21 and the first insulation pipe 2, and the cold medium is fed into the spiral plate heat exchanger 1 through the fourth insulation pipe 32, the cold medium inlet valve 31 and the third insulation pipe 3, so that the hot and cold mediums exchange heat in the spiral plate heat exchanger 1. Then the hot medium is discharged through the hot medium drain pipe 23 and the cold medium is discharged through the cold medium drain pipe 33.
