[0014] By adopting the above technical solution, the guide rod and the guide hole slide in cooperation to ensure that the shifting block slides conveniently in the sliding groove.

[0015] Furthermore, the guide rod passes through the spring, one end of the spring is welded to the slide groove, and the other end of the spring is welded to the shift block.

[0016] By adopting the above technical solution, the spring is mainly used to realize the automatic reset of the shift block after being shifted.

[0017] Furthermore, the shift block is slidably connected to the slide slot, and the portion of the slide slot that cooperates with the limiting rod is a hollow structure.

[0018] By adopting the above technical solution, it can be ensured that the limiting rod can be smoothly inserted into the slot so as to be reliably matched with the limiting hole.

[0019] Furthermore, the serpentine heat exchange tube is welded to the connecting main pipe and the connecting branch pipe, and the medium inlet pipe and the medium outlet pipe are respectively connected to the inlet and outlet of the heat exchange pipe network.

[0020] By adopting the above technical solution, it is possible to ensure uniform flow of the heat exchange medium in the heat exchange pipe network, thereby ensuring efficient heating of the objects.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0031] like Figure 2-Figure 4 As shown, a tube-sheet type heating plate in this embodiment includes a lower shell 2, an upper shell 1 is installed on the upper side of the lower shell 2, a quick-release component 4 is installed at the connection parts of the four corners of the lower shell 2 and the upper shell 1, and a heat exchange pipe network 5 is also installed in the lower shell 2. The heat exchange pipe network 5 can ensure the uniform flow of the heat exchange medium in the heat exchange pipe network 5 to ensure uniform heating of the objects and reduce energy consumption. The quick-release component 4 includes slots 403 opened at the four corners of the upper end of the lower shell 2, a slide groove 404 opened on the outer wall of the lower shell 2 and located on one side of the slot 403, a shift block 405 installed on one side of the slide groove 404, and a shift block 405 installed on the shift block 405 facing the slot 4 03, a limit rod 409 on the side wall, a guide rod 407 installed on the shift block 405 on the side facing away from the limit rod 409, a spring 406 installed on the outside of the guide rod 407, a guide hole 408 opened in the slide groove 404 on the side wall facing the guide rod 407, an insertion rod 401 installed at the four corners of the bottom end of the upper shell 1, and a limit hole 402 opened on the insertion rod 401 to cooperate with the limit rod 409, the heat exchange pipe network 5 includes a serpentine heat exchange tube 502 laid in parallel in the lower shell 2, a connecting main pipe 501 installed at both ends of the serpentine heat exchange tube 502, and a connecting branch pipe 503 installed between two adjacent serpentine heat exchange tubes 502.

[0032] Among them, when heating an object, the external heat exchange medium is circulated in the heat exchange pipe network 5 to ensure that the heating plate heats the object evenly. During later inspection and maintenance, it is only necessary to push the limit rod 409 out of the limit hole 402 by the push block 405, so that the plug rod 401 can be easily pulled out of the slot 403, thereby ensuring the convenient disassembly of the upper shell 1 and the lower shell 2, and facilitating efficient inspection and maintenance of the heating plate.

[0033] like Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, a medium inlet pipe 3 is installed in the middle of one side wall outside the lower shell 2, and a medium outlet pipe 6 is installed on the side wall of the outer wall of the lower shell 2 opposite to the medium inlet pipe 3. The serpentine heat exchange tube 502 is welded to the connecting main pipe 501 and the connecting branch pipe 503. The medium inlet pipe 3 and the medium outlet pipe 6 are respectively connected to the inlet and outlet of the heat exchange network 5, and the medium inlet pipe 3 and the medium outlet pipe 6 are respectively connected to the external cut-off circulation pipe, so that the heat exchange medium can flow conveniently in the heat exchange network 5. The plug rod 401 is welded to the upper shell 1, and the limiting hole 402 passes through the plug rod 401. After the plug rod 401 is inserted into the slot 403, the upper shell 1 and the lower shell 2 can be tightly fitted.

[0034] like Figure 2-Figure 4 As shown, in this embodiment, the limit rod 409 is welded to the shift block 405, and the limit rod 409 passes through the side wall of the slot 403 and is slidably connected to the side wall of the slot 403. Inserting the limit rod 409 into the limit hole 402 can limit the insertion rod 401 to ensure the stable closed installation of the upper shell 1 and the lower shell 2. The guide rod 407 is slidably connected to the guide hole 408, and the guide rod 407 is welded to the shift block 405. The guide rod 407 and the guide hole 408 slide in coordination to ensure that the shift block 405 slides conveniently in the slide groove 404.

The shift block 405 is slidably connected to the slide groove 404, and the part of the slide groove 404 that cooperates with the limit rod 409 is a hollow structure, which can ensure that the limit rod 409 can be smoothly inserted into the slot 403 so as to reliably cooperate with the limit hole 402.

[0036] The specific implementation process of this embodiment is as follows: when in use, the upper shell 1 and the lower shell 2 are first reliably closed under the action of the quick-release assembly 4, and the medium inlet pipe 3 and the medium outlet pipe 6 are respectively connected to the external medium circulation pipeline, and then the tube-sheet heat exchange plate only needs to be installed in the corresponding use position to put the tube-sheet heat exchange plate into use. During use, by installing a heat exchange pipe network 5 composed of a connecting branch pipe 503, a connecting main pipe 501 and a serpentine heat exchange pipe 502 in the lower shell 2, not only the heating plate heats the object more evenly when in use, but also the energy consumption of the heating plate when heating the object is greatly reduced. At the same time, the quick-release assembly 4 is used to fix the upper shell 1 and the lower shell 2, so that the heating plate can be later pulled out of the limiting rod 409 from the limiting hole 402 by the pull block 405, thereby realizing the convenient withdrawal of the plug rod 401 from the slot 403, ensuring the convenient disassembly of the upper shell 1 and the lower shell 2, so that the heating plate can be efficiently repaired and maintained.
