Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of molten salt heat exchanger equipment, in particular to a molten salt heat exchanger which is easy to disassemble and assemble. Background Art

[0002] A molten salt heat exchanger is a heat exchanger that uses molten salt as a working fluid. Molten salt is usually a mixture of sodium chloride and potassium chloride as the main components, and has a high specific heat capacity and thermal conductivity. Chloride molten salt is highly corrosive and prone to deliquescence. Because the molten salt heat exchanger needs to be regularly maintained and serviced, the existing molten salt heat exchanger is relatively cumbersome to disassemble due to its own structure. After the work is completed, the molten salt equipment must be cooled for a long time before it can be maintained. Its inspection and maintenance are time-consuming, which is not conducive to the production. Utility Model Content

[0003] In view of the shortcomings of existing molten salt heat exchangers, such as complicated disassembly and long time-consuming equipment inspection after operation, which is not conducive to production, the utility model provides a molten salt heat exchanger that is easy to disassemble and assemble, which is simple to disassemble and can facilitate disassembly while shortening the inspection time, which is beneficial to production.

[0004] The utility model provides the following technical solutions:

[0005] It includes a support frame, on which a heat exchanger body is installed, and heat exchanger connecting pipes and rotating tube covers are symmetrically arranged at both ends of the heat exchanger body in sequence. It is characterized in that a clamping structure is arranged around the connecting head of the heat exchanger body and the heat exchanger connecting pipe, and a linked rotating structure is arranged between the same side circumferences of the heat exchanger connecting pipe and the rotating tube cover.

[0006] It is further characterized by:

[0007] The clamping structure includes a rotating arc lock and a supporting arc lock, a rotating shaft is provided on a fixed block symmetrically installed at the top end of the supporting arc lock, a rotating block is symmetrically installed on one end of the rotating arc lock close to the supporting arc lock, and the rotating block is sleeved on the rotating shaft, and the supporting arc lock has a supporting and fixing effect on the heat exchanger body and the heat exchanger connecting pipe;

[0008] A support column is installed on the front of the connector of the heat exchanger connecting pipe, and a pipe protrusion is vertically installed on the peripheral surface closest to the rotating pipe cover;

[0009] The linked rotating structure includes a central support column, a telescopic rod and a double-headed rotating block. The central support column and the vertical side heads of the heat exchanger body are both equipped with telescopic cylinders. The free end head of the support column is provided with a through groove adapted to the telescopic rod body. The extended end of the piston rod of the telescopic cylinder and the tail of the telescopic rod are fixedly connected in the through groove of the support column. The head of the telescopic rod is rotatably connected to the tail of the arc block of the rotating pipe cover. One end of the double-headed rotating block is rotatably connected to the pipeline protrusion, and the other end is rotatably connected to the head of the arc block of the rotating pipe cover.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The setting of the clamping structure can realize the rapid fixation and detachment of the heat exchanger body and the heat exchanger connecting pipe. After the heat exchanger body is disconnected, it can be maintained and repaired, which greatly reduces the time consumption of maintenance and repair, indirectly improves the equipment operation efficiency, and is conducive to the production process;

[0012] The linked rotating structure can open the rotating tube cover at the first time to relieve the pressure of the heat exchanger that has completed the work, which reduces the waiting time and ensures the efficiency of disassembly and assembly, reduces the time required for detection, is convenient and fast, and is beneficial to improving production efficiency.

[0020] The utility model provides Figure 1-Figure 5A molten salt heat exchanger that is easy to disassemble and assemble is shown, which includes a support frame 3, on which a heat exchanger body 1 is installed, and heat exchanger connecting pipes 2 and rotating pipe covers 4 are symmetrically arranged at both ends of the heat exchanger body 1, and a clamping structure is arranged around the connecting head of the heat exchanger body 1 and the heat exchanger connecting pipe 2, and a linked rotating structure is arranged between the same side circumferences of the heat exchanger connecting pipe 2 and the rotating pipe cover 4;

[0021] See Figure 5 The clamping structure includes a rotating arc lock 9 and a supporting arc lock 10. A rotating shaft 13 is provided on a fixed block symmetrically installed at the top end of the supporting arc lock 10. A rotating block 14 is symmetrically installed on one end of the rotating arc lock 9 close to the supporting arc lock 10, and the rotating block 14 is sleeved on the rotating shaft 13. The supporting arc lock 10 has a supporting and fixing function for the heat exchanger body 1 and the heat exchanger connecting pipe 2.
