[0001] The utility model relates to the technical field of round-hole graphite heat exchangers, in particular to a round-hole graphite heat exchanger baffle structure. Background Art

[0002] The round block hole graphite heat exchanger is a heat exchange equipment with superior performance and wide application. It plays an important role in many industries. In order to improve the heat exchange effect, baffles are usually set in it to increase the residence time of the coolant.

[0003] A new type of round graphite heat exchanger is disclosed in the Chinese utility model patent application number: CN97243307.4, in which a straight-through graphite heat exchange block is installed in the shell, upper and lower heads are installed at both ends of the shell, and an external baffle is installed between the inner wall of the shell and the graphite heat exchange block. The new type of round graphite heat exchanger improves the heat exchange effect by setting the baffle.

[0004] However, the round-hole graphite heat exchanger will expand when heated, and due to its long longitudinal dimension, the relative displacement between the round-hole graphite heat exchanger at the top and the shell is particularly obvious. This displacement can easily lead to damage to the sealing performance between the baffle and adjacent components, thereby causing the baffle effect to be weakened or even fail.

[0005] Therefore, it is necessary to propose a round hole graphite heat exchanger baffle structure to solve the above problems. Utility Model Content

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Please refer to Figures 1-5 As shown, a baffle structure for a circular block hole graphite heat exchanger includes a shell 6. A plurality of circular block hole type graphite heat exchangers 5 are provided inside the shell 6. A baffle 4 is provided on the outer side of each circular block hole type graphite heat exchanger 5. The baffle 4 includes two sealing rings 12. The two sealing rings 12 are respectively sleeved at both ends of the circular block hole type graphite heat exchanger 5. Arc-shaped baffles 13 are provided on the sides of the two sealing rings 12 away from each other. Corresponding ends of the two arc-shaped baffles 13 are connected with a sealing strip 14. The arc-shaped baffles 13 and the sealing strip 14 are used to seal the gap between the outer wall of the circular block hole type graphite heat exchanger 5 and the inner wall of the shell 6. Preferably, the sealing rings 12, the arc-shaped baffles 13 and the sealing strip 14 are all made of elastic rubber; adjacent baffles 4 are symmetrically distributed, and multiple baffles 4 cooperate to enable the coolant to flow through multiple heat exchangers in an S-shaped path in sequence.

[0030] By separately providing a baffle 4 on the outer side of each circular block hole type graphite heat exchanger 5, the gap between the outer wall of the circular block hole type graphite heat exchanger 5 and the inner wall of the shell 6 is sealed under the action of the arc-shaped baffles 13 and the sealing strip 14. With the cooperation of multiple circular block hole type graphite heat exchangers 5, the coolant is enabled to flow through multiple circular block hole type graphite heat exchangers 5 in an S-shaped path in sequence; when the circular block hole type graphite heat exchanger 5 expands due to heat, the baffle 4 deforms following the circular block hole type graphite heat exchanger 5, avoiding the problem that the sealing effect weakens after frequent thermal expansion and contraction, resulting in baffle failure; at the same time, material leakage is avoided under the action of the sealing ring 12.

[0031] Specifically, a fixed seat 8 is fixedly connected to the bottom end of the housing 6, and a movable seat 2 is hermetically slidably arranged at the top end of the housing 6. A plurality of block-hole graphite heat exchangers 5 are arranged between the movable seat 2 and the fixed seat 8. Liquid outlets 3 and liquid inlets 7 are respectively arranged at the upper and lower ends of the housing 6, and a feed inlet and a discharge outlet are respectively formed on the movable seat 2 and the fixed seat 8.

[0032] Specifically, a feed inlet and a discharge outlet are respectively formed on the movable seat 2 and the fixed seat 8. The movable seat 2 and the housing 6 are connected by bolts, and a return spring 1 is sleeved outside the bolts. The return spring 1 is used to push the movable seat 2 to reset.

[0033] When the block-hole graphite heat exchanger 5 expands due to heat, it pushes the movable seat 2 to move upward, and the return spring 1 is compressed by the force. When the block-hole graphite heat exchanger 5 cools down, the return spring 1 pushes the movable seat 2 to reset, thereby ensuring the sealing effect at the connection of each block-hole graphite heat exchanger 5 and avoiding material leakage.

[0034] In some embodiments, in order to make the connection of the block-hole graphite heat exchanger 5 more stable and avoid its dislocation problem, a boss 9 is provided at the top end of the block-hole graphite heat exchanger 5, and a groove 15 adapted to the boss 9 is formed at the bottom end of the block-hole graphite heat exchanger 5.

[0035] When stacking, the boss 9 of the lower block-hole graphite heat exchanger 5 is inserted into the groove 15 of the upper block-hole graphite heat exchanger 5, and the boss 9 and the groove 15 cooperate with each other to limit its position.

[0036] In order to limit the sealing ring 12, annular grooves 10 adapted to the sealing ring 12 are formed at both ends of the block-hole graphite heat exchanger 5. Preferably, the thickness of the sealing ring 12 is slightly greater than the depth of the annular groove 10. When the block-hole graphite heat exchangers 5 are stacked, the sealing ring 12 deforms under force to seal the stacked joints, and at the same time, it can prevent the sealing ring 12 from shifting due to external force during use.

[0037] In order to limit the sealing strip 14, a strip-shaped groove 11 for limiting the sealing strip 14 is formed on the outer wall of the block-hole graphite heat exchanger 5. The strip-shaped groove 11 limits the sealing strip 14 to prevent it from shifting due to external force during use, making it more tightly abut against the inner wall of the housing 6, so that it can more effectively fill the gap and improve the sealing effect.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
