Technical Field

[0001] The utility model relates to the field of heat exchanger design, and particularly to a heat exchanger structure. Background Art

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials among two or more fluids at different temperatures. It enables heat to be transferred from a fluid at a higher temperature to a fluid at a lower temperature, so that the temperature of the fluid reaches the specified index of the process, to meet the requirements of process conditions. At the same time, it is also one of the main devices for improving energy utilization rate and occupies an important position in many industrial productions such as chemical industry, petroleum, power, food and others.

[0003] Chinese Patent with publication number CN112747609A discloses a heat exchanger structure, including a heat exchanger body, an oil passage housing and a water pipe.

[0038] The liquid inlet 3 is arranged at the top of the heat exchanger body 1, the valve 1 4 is rotatably arranged at one end of the liquid inlet 3 away from the heat exchanger body 1, the liquid outlet 5 is arranged at the bottom of the heat exchanger body 1, and the valve 2 6 is rotatably arranged at one end of the liquid outlet 5 away from the heat exchanger body 1.

[0039] The conveying mechanism includes a first shunt box 701, a feed inlet 702, a first connecting pipe 703, a spiral transportation assembly, a second connecting pipe 704, a second shunt box 705 and a discharge outlet 706;

[0041] The spiral transportation assembly is arranged at one end of the first connecting pipe 703 away from the first shunt box 701 and is used to spirally transport the material to be heat-exchanged in the connecting pipe out of the heat exchanger body 1;

[0042] The second connecting pipe 704 is arranged at the bottom of the spiral transportation assembly, the second shunt box 705 is arranged at the bottom of the second connecting pipe 704, and the discharge outlet 706 is arranged on the side of the second shunt box 705. Pour the material to be heat-exchanged into the first shunt box 701 through the feed inlet 702, and the first shunt box 701 then distributes the material into the first connecting pipes 703 respectively. There are five first connecting pipes 703. Then the material enters the second connecting pipe 704 through the spiral transportation assembly, then enters the second shunt box 705, and finally flows out from the liquid outlet 5, thereby completing the heat exchange work.

[0043] The spiral conveying assembly includes a circular ring slide rail 707, a rotating ring 708, a rotating pipe 709, spiral blades 710, a connecting shaft 711 and a fixing plate 712; the circular ring slide rail 707 is arranged at the end of the connecting pipe, the rotating ring 708 is rotatably arranged on the outside of the circular ring slide rail 707, the rotating pipe 709 is arranged on the side of the rotating ring 708, the spiral blades 710 are arranged on the inside of the rotating pipe 709, the connecting shaft 711 is arranged on the inside of the spiral blades 710, the fixing plate 712 is arranged on the outside of the rotating pipe 709, there are multiple fixing plates 712, and the stirring mechanism can drive the fixing plate 712 to rotate, thereby driving the rotating pipe 709 to rotate in the circular ring slide rail 707. The rotation of the rotating pipe 709 drives the rotation of the spiral blades 710, and the rotation of the spiral blades 710 can continuously drive the materials above to be conveyed downward, and can drive the materials to be transported downward at the same speed, avoiding the incomplete heat exchange caused by the direct and rapid fall of the materials, so that the effect of heat exchange and cooling is better.

[0044] Embodiment 2

[0045] As Figure 5 shown, a heat exchanger structure proposed by the present utility model, compared with Embodiment 1, this embodiment details the structure of the stirring mechanism:

[0046] The stirring mechanism includes a motor 801 and a stirring assembly; the motor 801 is arranged at the top of the heat exchanger body 1; the stirring assembly is arranged at the output end of the motor 801 and is used to stir the coolant in the heat exchanger body 1. The stirring assembly includes a rotating shaft 802, stirring blades 803, a dial block 804 and a connecting frame 805; the rotating shaft 802 is arranged at the output end of the motor 801, the stirring blades 803 are arranged on the outside of the rotating shaft 802, the dial block 804 is arranged at one end of the stirring blade 803 away from the rotating shaft 802, and the connecting frame 805 is arranged at the bottom of the rotating shaft 802. By driving the rotating shaft 802 to rotate through the motor 801, the rotating shaft 802 drives a plurality of stirring blades 803 to rotate together. When the stirring blades 803 rotate, they can stir the coolant, avoiding the heat exchange treatment of the materials in the connecting pipe and the rotating pipe 709 by the same coolant all the time, so that the heat exchange is more uniform and the effect is better. At the same time, when the stirring blades 803 rotate, they will drive the dial block 804 to rotate, and the rotation circumference of the dial block 804 coincides with the fixing plate 712. Therefore, when the dial block 804 rotates to near the fixing plate 712, it can drive the fixing plate 712 to rotate.

[0047] In summary, when the utility model is in use, open valve 14 to pour the coolant into the heat exchanger body 1 through the liquid inlet 3, so as to supplement the coolant. After the coolant is full, pour the material to be heat-exchanged into the first shunt box 701 through the feed inlet 702. The first shunt box 701 then distributes the material into the first connecting pipes 703 respectively. There are five first connecting pipes 703, and then it enters the rotating pipe 709. At the same time, the motor 801 drives the rotating shaft 802 to rotate, and the rotating shaft 802 drives a plurality of stirring blades 803 to rotate together. When the stirring blades 803 rotate, they can stir the coolant. At the same time, when the middle stirring blade 803 rotates, it will drive the dial 804 to rotate. There is an overlapping part between the rotation circumference of the dial 804 and the fixed plate 712. Therefore, when the dial 804 rotates to near the fixed plate 712, it can drive the fixed plate 712 to rotate, thereby driving the rotating pipe 709 to rotate in the circular slide rail 707. The rotation of the rotating pipe 709 drives the spiral blade 710 to rotate. The rotation of the spiral blade 710 can continuously drive the upper material to be conveyed downward, and can drive the material to be transported downward at the same speed. Then it enters the second connecting pipe 704, and then enters the second shunt box 705, and finally flows out from the liquid outlet 5, thus completing the heat exchange work. When the coolant needs to be replaced, open valve 26 to pour out the coolant in the heat exchanger body 1 through the liquid outlet 5.

[0048] The above has described in detail the embodiments of the present utility model in conjunction with the drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
