Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a high-efficiency heat exchanger for chemical production. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. It plays an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] The inventors found in their daily work that when the heat exchanger is in use, the air pipes at both ends are directly connected to the connecting pipes. Due to the long-term impact and oxidation corrosion of the gas, gaps will appear between the air pipes and the connecting pipes, which will lead to air leakage, thereby reducing the heat exchange efficiency of the heat exchanger.

[0004] In order to solve the problem that long-term impact and oxidation corrosion of gas will cause gaps between the air pipe and the connecting pipe, which will lead to air leakage and reduce the heat exchange efficiency of the heat exchanger, the prior art solves the problem by reinforcing the connection between the air pipe and the connecting pipe with tools such as iron wire or cable ties. The present utility model adopts another solution. Utility Model Content

[0007] The effect achieved by the above-mentioned components is: by setting two half rings, under the action of the threaded rod, the threaded rod is rotated, and the threaded rod will move on the inner wall of the fixed block, so that it is convenient to adjust the half rings through the threaded rod, and drive the two half rings to approach the connecting pipe and the air pipe, so that the two half rings completely clamp the outer surface of the connection between the connecting pipe and the air pipe, which is beneficial to prevent gas from overflowing from the connection between the air pipe and the connecting pipe, and is beneficial to improving the heat exchange efficiency of the heat exchanger.

[0015] The effect achieved by the above components is: by setting the card block and the card slot, when the two rubber plates approach each other under the action of the two clamping plates, the card block will gradually enter the inner wall of the card slot to assist in sealing the connection between the two rubber plates, thereby further improving the sealing performance of the semi-ring on the connection between the connecting pipe and the trachea.

[0017] The effect achieved by the above components is: by setting the positioning plate, the mounting plate is inserted into the inner walls of the two mounting grooves on the two support blocks, so that the mounting grooves can fix the positioning plate. At the same time, the positioning plate can increase the contact area between the support block and the ground, making the heat exchanger more stable as a whole, and the positioning plate is detachable, which is convenient for maintenance and replacement of the positioning plate.

[0018] Preferably, one side of the positioning plate is symmetrically fixedly connected with a threaded pin, and the threaded pin can be respectively inserted into the inner walls of the two supporting blocks.

[0019] The effect achieved by the above components is: by setting a threaded pin and inserting the threaded pin into the inner wall of the support block, the support block and the positioning plate can be fixed to each other, preventing the positioning plate from easily detaching from the inner wall of the installation groove.

[0020] Preferably, a hexagonal block is provided on the outer surface of the threaded pin, the threaded pin is threadedly inserted into the inner wall of the hexagonal block, and one side of the hexagonal block abuts against one side of the support block.

[0021] The effect achieved by the above-mentioned components is: by setting the hexagonal block, placing the hexagonal block at one end of the threaded pin at the same time, rotating the hexagonal block so that one side of the hexagonal block abuts against the top of the support block, the hexagonal block can further limit the position between the threaded pin and the support block to prevent the threaded pin from detaching from the inner wall of the support block.

[0022] Compared with the prior art, the advantages and positive effects of the utility model are:

[0023] In the utility model, by setting two half rings, under the action of the threaded rod, the threaded rod can move on the inner wall of the fixed block, so that the half rings can be adjusted by the threaded rod, driving the two half rings to approach the connecting pipe and the air pipe, so that the two half rings completely clamp the outer surface of the connection between the connecting pipe and the air pipe, which is beneficial to prevent gas from overflowing from the connection between the air pipe and the connecting pipe, and is beneficial to improving the heat exchange efficiency of the heat exchanger.
