[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0019] Example 1: like Figure 1 As shown, a modular convection structure includes four convection columns, an inlet assembly, and an outlet assembly. like Figure 2 As shown, the convection column 4 is used to separate mixed components. The convection column 4 includes a shell 41, with an inlet end 44 and an outlet end 45 connected to both ends of the shell 41. A convection column polymer 42 is disposed in the middle of the shell 41, and a filter element 43 is disposed inside the convection column polymer 42. The mixed components enter from the inlet end 44, are filtered and separated by the filter element 43, and are discharged from the outlet end 45. The inlet assembly is connected to the inlet end 44 and is used to input the mixed components into the convection column 4. The outlet assembly is connected to the outlet end 45 and is used to discharge the components separated by the filter element 43. The convection column polymer 42 is used to support the filter element 43.

[0020] The modular convection structure in this embodiment uses inlet and outlet components, enabling multiple convection columns 4 to be connected in parallel. The number and volume of convection columns 4 can be freely combined according to production capacity requirements, achieving redundant design. Moreover, it can be easily scaled up seamlessly from small-scale trials to production scale, significantly shortening the scale-up cycle and reducing verification costs.

[0021] The diameter of the convection column 4 at the inlet end 44 is larger than the diameter of the convection column 4 at the outlet end 45; this setting can remind the operator and prevent the operator from installing the convection column 4 against the flow.

[0022] The inlet assembly includes an inlet main pipe 1 and four inlet branch pipes 2. Each inlet branch pipe 2 corresponds to a convection column 4. One end of each inlet branch pipe 2 is connected to the inlet main pipe 1, and the other end of each inlet branch pipe 2 is connected to the inlet end 44.

[0023] The inlet branch pipe 2 is equipped with a flow control valve 3, which controls the opening and closing of the inlet branch pipe 2; the flow control valve 3 is selected from Beijing Jingliang Technology's ACU10FD-MC.

[0024] The outlet assembly includes an outlet main pipe 7 and four outlet branch pipes 5. Each outlet branch pipe 5 corresponds to a convection column 4. One end of each outlet branch pipe 5 is connected to the outlet main pipe 7, and the other end of each outlet branch pipe 5 is connected to the outlet end 45.

[0025] The outlet branch pipe 5 is equipped with a flow detector 6, which is used to detect the flow rate of the outlet branch pipe 5; the flow detector 6 is a Keyence FD-Q.

[0026] During operation, flow detector 6 detects the flow of the corresponding outlet branch pipe 5 and feeds it back to the software control center. The software control center uses a Siemens CNC system to adjust the flow control valve 3 to ensure consistent flow across all modules. Each convection column 4 module can independently maintain a high throughput flow rate. After parallel connection, the total processing capacity has a strictly linear relationship with the number of convection columns 4, thus overcoming the limitation that the efficiency of a single column decreases as its size increases. Moreover, the number and volume of convection columns 4 can be freely combined according to production capacity requirements to achieve redundant design and improve system fault tolerance. In addition, the combination of the number and volume of convection columns 4 can achieve seamless scaling up from pilot testing to production scale, shortening the scaling-up cycle.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
