In the process of chemical, energy, petroleum, pharmaceutical and other industries, heat transfer and control are required, and graphite heat exchanger is widely used as an efficient heat exchange equipment.

[0003] Among them, the "A High-efficiency Graphite Heat Exchanger" disclosed in the application number "CN220437205U" has solved the various drawbacks of the existing graphite heat exchanger, such as the impurities filtered out easily cause the blockage of the pipeline, affect the flow of the medium, are inconvenient to clean the filtered impurities, and reduce the heat exchange efficiency. After further search, it was found that the "A High-efficiency Graphite Heat Exchanger" disclosed in the application number "CN204963625U" has effectively solved the problem that the parts of the graphite heat exchanger that contact with the material are all impregnated by the technical structure of the graphite cylinder, shell, graphite heat exchange block and flow equalizing plate. Graphite is a brittle material and cannot withstand high-speed erosion or impact of solid impurities or crystals. However, in actual use, graphite heat exchangers with similar structures still have many defects, such as: the existing graphite heat exchanger is not convenient for disassembly of the graphite heat exchange block. Although the blockage of the graphite heat exchange block can be reduced through design, the equipment will still be fouled or contaminated after long-term use. In addition, due to the complex internal structure of the graphite heat exchanger, it is not convenient to clean it, and the heat exchanger is prone to blockage, which affects the heat exchange effect. Therefore, it is necessary to design a high-efficiency graphite heat exchanger. Utility Model Content

[0025] Please combine Figure 1-5 The present embodiment provides a high-efficiency graphite heat exchanger, comprising an upper head 1, an outer shell 2, an inner shell 3, a graphite heat exchange block 4 and a lower head 5. A heat flow input pipe 101 is fixedly installed on one side of the upper head 1, a limit seat 102 is fixedly installed on the bottom of the upper head 1, and the outer shell 2 is movably installed on the bottom of the limit seat 102.

[0026] By providing a second limiting groove 303 in the inner shell 3 and installing a corresponding second limiting strip 401 on the surface of the graphite heat exchange block 4, it is convenient for workers to disassemble and replace the graphite heat exchange block 4 that is severely corroded or worn. The workers do not need to spend too much time and energy on maintenance operations, which improves maintenance efficiency, thereby extending the service life of the heat exchanger, reducing maintenance and replacement costs, and improving equipment reliability.

[0027] By opening corresponding cleaning grooves 201 and cleaning ports 301 on the surfaces of the outer shell 2 and the inner shell 3, and opening a cleaning port 402 on the surface of the graphite heat exchange block 4, when the heat exchanger has been used for a long time, the staff can rotate the outer shell 2 to align the cleaning groove 201 with the cleaning port 301, which can facilitate the staff to flush clean water into the interior of the graphite heat exchange block 4, reducing the heat exchange effect caused by blockage or fouling inside the graphite heat exchange block 4, and ensuring the heat exchange effect of the heat exchanger.

[0028] The inner wall of the limiting seat 102 is provided with a first limiting groove 103, and a filter plate 104 is fixedly mounted inside the limiting seat 102. The first limiting groove 103 ensures that the housing 2 can be rotated and adjusted, and the filter plate 104 prevents impurities in the heat flow from entering the interior of the graphite heat exchange block 4 and causing blockage.

[0029] A cleaning slot 201 is defined on one side of the housing 2. A handle 202 is fixedly mounted on the front end of the housing 2. A first retaining bar 203, which is associated with the first retaining slot 103, is fixedly mounted on the bottom of the housing 2. The cleaning slot 201 allows workers to easily flush clean water into the interior of the graphite heat exchange block 4. By pulling the handle 202, the housing 2 can be rotated, with the first retaining bar 203 on the inner wall of the retaining seat 102 aligned with the first retaining slot 103.

[0030] The housing 2 and the limiting seat 102 are movably mounted between the first limiting bar 203 and the first limiting groove 103. Through the movable installation between the housing 2 and the limiting seat 102, the housing 2 can be rotated to another position when the staff does not need to clean the inside of the graphite heat exchange block 4.

[0031] A cleaning port 301 is provided on one side of the inner shell 3 and is associated with the cleaning tank 201. A second limiting groove 303 is provided on the inner wall of the inner shell 3. When the cleaning tank 201 is aligned with the cleaning port 301, it is convenient for the staff to flush clean water into the interior of the graphite heat exchange block 4.

[0032] Second limiting bars 401, which are fixed to the front and rear ends of the graphite heat exchange block 4 and are associated with the second limiting grooves 303, are also fixed to the surface of the graphite heat exchange block 4. A cleaning port 402, which is associated with the cleaning groove 201, is provided on the surface of the graphite heat exchange block 4. The alignment of the second limiting grooves 303 and the second limiting bars 401 facilitates the removal and replacement of severely corroded or worn graphite heat exchange blocks 4. The cleaning port 402 allows clean water to be flushed into the block.

[0033] The graphite heat exchange block 4 and the inner shell 3 are movably mounted between the second limiting groove 303 and the second limiting bar 401. The movably mounted graphite heat exchange block 4 and the inner shell 3 facilitates the disassembly and installation of the graphite heat exchanger 4 by the staff.

[0034] The implementation principle of a high-efficiency graphite heat exchanger in the embodiment of the present application is as follows: the heat fluid that needs to be exchanged is input into the interior of the upper head 1 through the heat fluid input pipe 101, and the filter plate 104 can be used to prevent impurities in the heat fluid from entering the interior of the graphite heat exchange block 4, thereby causing blockage. The cooling fluid can be input into the interior of the outer shell 2 through the cooling fluid input pipe 302, and the heat fluid can be cooled by using the graphite heat exchange block 4. Corresponding cleaning grooves 201 and cleaning ports 301 are opened on the surfaces of the outer shell 2 and the inner shell 3. When the heat exchanger has been used for too long, the staff can pull the handle 202 to move the outer shell 2, and use the first limit bar 203 on the inner wall of the limit seat 102 to match the first limit groove 103. , rotate. When the cleaning tank 201 coincides with the cleaning port 301, it is convenient for the staff to flush clean water from the cleaning port 402 into the interior of the graphite heat exchange block 4, reducing the heat exchange effect caused by blockage or scaling inside the graphite heat exchange block 4, thereby ensuring the heat exchange effect of the heat exchanger. When the heat flow cools down, the cooled heat flow can be discharged from the heat exchanger through the heat flow output pipe 501 at the bottom of the shell 2. The upper head 1 and the lower head 5 can ensure the sealing of the heat exchanger. When the staff does not need to clean the inside of the graphite heat exchange block 4, the cleaning tank 201 is rotated to a position where it does not coincide with the cleaning port 301, which can reduce a certain amount of heat loss and reduce the situation that affects the heat exchange efficiency.

[0035] When the heat exchanger has been working for a long time, the interior of the graphite heat exchange block 4 may be severely corroded or worn. By opening a second limit groove 303 in the inner shell 3 and installing a corresponding second limit strip 401 on the surface of the graphite heat exchange block 4, the staff can conveniently disassemble and replace the graphite heat exchange block 4 that is severely corroded or worn. The staff does not need to spend too much time and energy on maintenance operations, which improves the maintenance efficiency, thereby extending the service life of the heat exchanger, reducing maintenance and replacement costs, and improving equipment reliability.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
