[0029] Sealing connecting device 1 is the key component for realizing detachable sealing connection between baffling heat exchange device 2 and tank body 3. Figure 2 As shown in the figure, the specific structure of sealing connecting device 1 includes mounting cylinder 104, lead-out cylinder 302, sealing support 110, sealing pressing cylinder 109 and multiple sealing elements.

[0030] Mounting cylinder 104 is a cylindrical structure, one end of which is welded and fixed on the outer wall of tank body 3, coaxially arranged with baffling heat exchange mounting hole 301.

The inner diameter of the sealing support 110 is slightly larger than the outer diameter of the baffle heat exchange device 2, and an annular gap is formed therebetween. A plurality of polytetrafluoroethylene sealing rings 102 (four are preferably arranged in the embodiment) are sequentially sleeved in the annular gap in the axial direction, for realizing the radial sealing between the sealing support 110 and the baffle heat exchange device 2. An inwardly protruding inner stop ring 114 is arranged on the inner wall of the end of the sealing support 110 close to the first flange 112, for axially limiting the polytetrafluoroethylene sealing ring 102.

[0035] During installation, the first flange 112 of the sealing support 110 is connected and fixed with the installation ring 101 sleeved on the lead-out cylinder 302 through bolts. In order to enhance the sealing performance at the connection position, an annular elastic sealing ring 113 is arranged between the first flange 112 and the installation ring 101. Meanwhile, an O-shaped sealing ring 111 is arranged in the triangular area formed between the inner stop ring 114, the first polytetrafluoroethylene sealing ring 102 close to the inner stop ring 114 and the outer wall of the baffle heat exchange device 2, for forming auxiliary sealing.

[0036] The second flange 103 of the sealing support 110 is connected and fixed with the fixed flange 105 of the sealing pressure cylinder 109 through bolts.

[0037] In order to further enhance the axial fixing stability of the baffle heat exchange device 2, an annular groove 208 is arranged on the outer wall of the end of the baffle heat exchange device 2 penetrating the mounting cylinder 104, and a pressing ring 108 is sleeved on the annular groove 208, and the outer wall of the pressing ring 108 is fixedly connected with a second mounting plate 107. The second mounting plate 107 and the first mounting plate 106 are connected and fixed through bolts, so that the end of the baffle heat exchange device 2 is fixedly connected with the mounting cylinder 104, and axial movement of the baffle heat exchange device 2 during work is prevented.

[0038] As shown in Figure 1 The cover body 5 is fixedly installed on the upper end of the tank body 3, and the cover body 5 and the tank body 3 are sealed through flange connection. The stirring motor 6 is fixedly installed on the cover body 5, the motor shaft of the stirring motor 6 penetrates the cover body 5 and extends into the tank body 3, and the axial flow type stirrer 12 is fixedly connected at the end of the motor shaft. The axial flow type stirrer 12 can push the material to form axial circulating flow in the tank, and the mixing effect is enhanced.

[0039] In addition, the utility model also sets up the baffle plate 10 for further improving the flow state of the material in the tank. The upper mounting flange 7 is fixed on the upper end of the baffle plate 10, the baffle plate mounting hole is formed in the corresponding position of the top of the tank body 3, and the lower mounting flange 8 is fixed on the baffle plate mounting hole. The lower end of the baffle plate 10 is inserted into the tank body 3 through the baffle plate mounting hole, and the upper mounting flange 7 and the lower mounting flange 8 are connected and fixed through bolts, so that the detachable installation of the baffle plate 10 is realized. The part of the baffle plate 10 extending into the tank body 3 is also a glass lining surface.

[0040] As shown in Figure 1 The side wall and the bottom surface of the tank body 3 are provided with the hollow heat exchange interlayer 11, the interlayer is a double-layer structure, and a heat exchange medium flow space is formed in the interlayer. The interlayer medium inlet 9 and the interlayer medium outlet 14 are arranged on the outer wall of the hollow heat exchange interlayer 11 and are respectively used for connecting external heat exchange medium circulating pipelines. The hollow heat exchange interlayer 11 and the baffle heat exchange device 2 jointly constitute an inner-outer double heat exchange structure, and can be selected to be used independently or to work cooperatively according to process requirements, so as to meet the temperature control requirements in different reaction stages.

[0041] The working principle of the utility model is as follows:

[0042] When the reaction is needed, the reaction material is put into the tank body 3 through the feeding port 4, the stirring motor 6 is started, the shaft flow stirrer 12 is rotated to stir and mix the material.

[0043] When the baffle heat exchange device 2 is started, the heat exchange medium enters from the joint flange 207 (the inlet end), sequentially flows through the first straight pipe part 201, the right-angle elbow pipe part 202, the first reducing pipe 203, the thick pipe part 204, the second reducing pipe 205 and the second straight pipe part 206, and finally flows out from the joint flange 207 (the outlet end) at the other end. In the process, the heat exchange medium exchanges heat with the pipe wall of the thick pipe part 204, and the heat is transferred to the material in the tank body 3 through the pipe wall to realize heating or cooling of the material.

[0044] The baffle heat exchange device 2 forms an L-shaped baffle structure inside the tank body 3, not only plays a heat exchange role, but also changes the flow direction of the material, plays a baffle guiding role, and enhances the mixing effect. The shaft flow stirrer 12 pushes the material to flow downward, changes the flow direction after meeting the baffle heat exchange device 2 and the baffle plate 10, forms a complex turbulent flow state, and further strengthens the heat transfer and mass transfer process.

[0045] The sealing connection device 1 ensures the sealing reliability of the connection between the baffle heat exchange device 2 and the tank body 3 through multiple sealing structures, prevents the heat exchange medium from leaking into the tank body 3 or the material in the tank from leaking out. When the baffle heat exchange device 2 needs to be overhauled or replaced, only the connecting bolts of the second mounting plate 107 and the first mounting plate 106, the connecting bolts of the fixed flange 105 and the second flange 103, and the connecting bolts of the first flange 112 and the mounting ring 101 are sequentially disassembled, the whole baffle heat exchange device 2 can be extracted from the tank body 3, without cutting the tank body 3, and the operation is simple and will not damage the enamel layer of the tank body 3.

[0046] The above describes only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
