DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, this embodiment proposes a pharmaceutical intermediate synthesis partition wall heat exchanger, comprising

[0028] a pair of cavity shells 1, with an outer shell 2 connected between the cavity shells 1;

[0029] The docking circulation component 3 is arranged between the cavity shells 1, and the docking circulation component 3 includes a multi-segment pipe 3-1, which is installed inside the cavity shell 1. The lower end of the multi-segment pipe 3-1 is located outside the cavity shell 1, and the multi-segment pipe 3-1 is provided with a plurality of docking pipes 3-2, which are fixed in the side surface of the cavity shell 1. The cavity shell 1 is provided with a plurality of inner pipes 3-3, which pass through the two side surfaces of the cavity shell 1. The movable sleeve in the side surface of the cavity shell 1 is connected with a mobile pipe 3-4, and one end of the mobile pipe 3-4 is provided with a sealing layer 3-5. The sealing layer 3-5 is sealed and fitted with the inner surface of the cavity shell 1, a docking sleeve 3-6 is provided at one end of the movable tube 3-4, a spring 3-7 is connected to the outer sleeve of the movable tube 3-4, a heat exchange cavity plate 3-8 is inserted and connected between the docking sleeve 3-6 and the docking tube 3-2, a transmission rod 3-9 is connected between the docking sleeves 3-6, a pull rod 3-10 is connected to the surface of the transmission rod 3-9, the pull rod 3-10 is movably sleeved in the inner tube 3-3, an anti-slider 3-11 is provided at one end of the pull rod 3-10, a plurality of heat exchange plates 3-12 are provided on both opposite surfaces of the heat exchange cavity plate 3-8, and an inlet pipe 3-13 is provided on the top of the cavity shell 1.

[0030] In this embodiment, in order to achieve the effect of being able to replace the heat exchange cavity plate 3-8 separately, a docking circulation component 3 is designed. Multiple sections of pipes 3-1 are provided inside the two cavity shells 1, and multiple docking pipes 3-2 are provided. The docking pipes 3-2 are located outside the cavity shell 1. The docking pipes 3-2 on the surfaces of the two cavity shells 1 have different heights. A movable pipe 3-4 is provided on the surface of the cavity shell 1 opposite to the docking pipe 3-2. The movable pipe 3-4 is movably mounted in the cavity shell 1 and can be moved. A sealing layer 3-5 and a docking sleeve 3-6 are respectively provided at both ends of the movable pipe 3-4. The sealing layer 3-5 is attached to the inner surface of the cavity shell 1. The surface of the movable pipe 3-4 is mounted with a spring 3-7, so that the movable pipe 3-4 can achieve the effect of elastic expansion and contraction. A heat exchange cavity plate 3-8 is inserted and connected between the docking pipe 3-2 and the docking sleeve 3-6 for circulating liquid for heat exchange and performing heat exchange. Both surfaces of the cavity plate 3-8 are provided with multiple heat exchange plates 3-12 to enhance the temperature transfer effect and improve the heat exchange efficiency. An inner tube 3-3 is installed in the cavity shell 1. Both ends of the inner tube 3-3 are open structures. A transmission rod 3-9 is connected between the two docking sleeves 3-6. A pull rod 3-10 is fixed on the surface of the transmission rod 3-9. The pull rod 3-10 passes through the inner tube 3-3 and is located at the other end. An anti-slider 3-11 is fixed to one end of the pull rod 3-10. The docking sleeve 3-6 can be pulled by the anti-slider 3-11 to shrink the movable tube 3-4 and separate it from the heat exchange cavity plate 3-8, making it easier to remove the heat exchange cavity plate 3-8. The liquid flows into the inlet pipe 3-13 at the top of the cavity shell 1, enters the interior of the cavity shell 1, and then passes through the movable tube 3-4 into the heat exchange cavity plate 3-8, and is finally discharged at the bottom of the multi-segment pipe 3-1, achieving the heat exchange effect during the flow.

[0031] Furthermore, both relative surfaces of the heat exchange cavity plate 3-8 are concave transition structures.

[0032] In this embodiment, the heat exchange fins 3-12 are located on the surface of the groove portion through the transition structure of the inner groove, so that there are gaps between the heat exchange fins 3-12 of each layer of heat exchange cavity plate 3-8 to facilitate heat exchange.

[0033] Furthermore, the cross section of the heat exchange plate 3-12 is V-shaped, and both ends of the heat exchange plate 3-12 are open structures.

[0034] In this embodiment, the V-shaped structure enables the heat exchange fins 3-12 to exchange temperature with each other, thereby enhancing heat dissipation and achieving a better heating effect.

[0035] Furthermore, the connection directions of the plurality of heat exchange cavity plates 3 - 8 are opposite to each other, and the opposite heat exchange fins 3 - 12 are staggered with each other.

[0036] In this embodiment, by arranging the heat exchange cavity plates 3 - 8 of each layer in opposite directions, different heat exchange liquids are respectively introduced into the cavity shells 1 on both sides, thereby achieving a heat exchange effect.

[0037] Furthermore, columns 4 are provided at both ends of the bottom of the cavity shell 1 .

[0038] In this embodiment, by installing the columns 4, a certain distance is maintained between the bottom of the cavity shell 1 and the ground, thereby avoiding affecting the heat exchange effect.

[0039] When heat exchange is required, the liquid is connected to the inlet pipe 3-13 at the top, enters the internal port of the cavity shell 1, flows into the interior of the heat exchange cavity plate 3-8 through the movable tube 3-4, and heat exchange is performed during the flow. The liquid then enters the multi-section pipe through the docking tube 3-2 and is discharged at the bottom. When the heat exchange cavity plate 3-8 needs to be replaced, hold the anti-slider 3-11 on one side and pull the pull rod 3-10 to make the movable tube 3-4 shrink inward on the surface of the cavity shell 1. When shrinking, the docking sleeve 3-6 is separated from the heat exchange cavity plate 3-8, and then the heat exchange cavity plate 3-8 can be pulled out of the docking tube 3-2.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
