[0002] The core-extractable silicon carbide heat exchanger is an innovative and efficient heat exchange device made of high-performance silicon carbide ceramic material. The silicon carbide material gives it excellent resistance to extreme corrosion, high thermal conductivity, excellent thermal shock resistance and ultra-high mechanical strength. It can stably cope with harsh working conditions such as strong acids, strong alkalis, high temperature and high pressure for a long time. This equipment is widely used in heat exchange processes of highly corrosive media in chemical, pharmaceutical, environmental protection, metallurgical and other fields, significantly improving process safety, heat transfer efficiency and equipment service life. It is a key device for achieving energy saving, consumption reduction and safe production.

[0003] Traditional heat exchangers are prone to heat loss due to their inherent heat conduction, which increases heat loss. Furthermore, the maintenance process of traditional silicon carbide heat exchangers is relatively cumbersome, affecting the working efficiency of the equipment.

A sliding button allows the locking column and limiting bracket to move, and a spring allows for the unlocking of the mounting block and sleeve, as well as the disassembly of the mounting block. This mechanism enables the replacement of the heat-conducting core tube, effectively improving equipment maintenance efficiency. The sliding button then allows for quick fixing, further enhancing installation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A core-removable silicon carbide heat exchanger includes a support base, a protective mechanism provided on the upper surface of the support base, and the protective mechanism includes an outer shell fixedly connected to the upper surface of the support base. An impact-resistant layer, a heat insulation layer, a functional layer and an inner liner are sequentially fixedly connected to the inner wall of the outer shell. The inner liner is provided with a fixing mechanism on both outer walls. The fixing mechanism includes a sleeve fixedly connected to the outer walls of both sides of the inner liner. The sleeve is provided with an installation block inside. The installation block is provided with a spring inside.

Then, the sliding button can be used for quick fixing, which can effectively improve the installation efficiency.

The air inlet pipe passes through the outer shell, the impact-resistant layer, the heat insulation layer, the inner liner, and the functional layer. The above technical solutions, by setting up an outer shell, an impact-resistant layer, a heat insulation layer, an inner liner, and a functional layer, can effectively improve the service life of the equipment.

[0009] Furthermore, the mounting block has two cavities inside, and the spring and the limiting bracket slide inside the cavities; The above technical solution provides space for the spring to move by setting up a cavity.

[0010] Furthermore, the snap-fit ​​post engages with the sleeve, and the sliding button slides on the outer wall of the mounting block; The above technical solution allows the mounting block to be fixed in place using a sliding button.

[0011] Furthermore, an inlet pipe is fixedly connected to the upper end of the outer wall of one of the fixed frames, and an outlet pipe is fixedly connected to the lower end of the outer wall of the other fixed frame. The above technical solution allows liquid to flow out through the outlet pipe.

[0012] Furthermore, an air outlet pipe is fixedly connected to the lower end of the outer wall of the outer shell near the middle, and a fixing flange is fixedly connected to the side of the fixing bracket near the outer shell. The above technical solution allows the entire device to be secured using a fixed flange.

[0013] Furthermore, a protective shell is fixedly connected to the outer wall of the fixed flange, and multiple heat-conducting core tubes are provided inside the mounting block; The above technical solution allows water to be heated via a heat-conducting core tube.
