A modular convection device

Abstract

This utility model discloses a modular convection device, including a shell, several convection units, an inlet unit, and an outlet unit. The convection units are evenly distributed in the shell and are used to separate mixed components. Each convection unit includes a convection chamber, in the middle of which a support layer is provided, and a filter element is provided in the support layer. The inlet unit is located at the bottom of the shell and is used to input the mixed components into the convection column. The outlet unit is located at the top of the shell and is used to discharge the components separated by the filter element. The mixed components enter the convection chamber from the inlet unit, are filtered and separated by the filter element, and are discharged from the outlet unit. The modular convection device of this utility model can set multiple convection units in the shell, without increasing the size of a single column. It only requires selecting shells with different numbers of convection units according to the production capacity requirements to perform component separation, realizing redundant design, and facilitating seamless scale-up from pilot-scale to production scale, significantly shortening the scale-up cycle and reducing verification costs.

[0017] 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.

[0018] 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] Example 1: like Figure 1-2 As shown, a modular convection device includes a housing 2. A convection unit, evenly distributed in the housing 2, is used to separate mixed components. The convection unit includes a convection chamber, a support layer 5 is provided in the middle of the convection chamber, and a filter element 6 is provided in the support layer 5. The inlet unit, located at the bottom of housing 2, is used to input the mixed components into the convection column; The outlet unit, located at the top of the housing 2, is used to discharge the components separated by the filter element 6; The mixed components enter the convection chamber from the inlet unit, are filtered and separated by filter element 6, and are discharged from the outlet unit.

[0021] Both the support layer 5 and the filter element 6 are annular. The bottom of the support layer 5 is also provided with a bracket, which is fixed to the bottom of the convection chamber. The bracket has through holes for passing through the mixed components and is used to support and limit the support layer 5 and the filter element 6.

[0022] The housing 2 includes an upper cover and a base. The outlet pipe 3 is located inside the upper cover, and the convection unit and the inlet pipe 1 are both located on the base. The upper cover is located on top of the base. The upper cover and the base allow operators to quickly assemble and disassemble the support layer 5 and the filter element 6.

[0024] The inlet unit includes an inlet pipe 1, and the liquid inlet chamber 4 is connected to the inlet pipe 1.

[0025] The outlet unit includes an outlet pipe 3, and the collection chamber 7 is connected to the outlet pipe 3.

[0026] The support layer 5 is a convection column polymer filler layer.

[0027] The diameter of the end of the housing 2 facing the inlet unit is larger than the diameter of the end of the housing 2 facing the outlet unit; this setting can remind the operator and prevent the operator from installing the anti-flow column 4.

[0028] Example 2: like Figure 3-4 As shown, compared to Embodiment 1, the difference in this embodiment is that there are two convection units.

[0029] Example 3: like Figure 5-6 As shown, compared to Embodiment 2, the difference in this embodiment is that there are four convection units.

[0030] Multiple convection units are connected in parallel, and the total processing capacity of the entire device is strictly linearly related to the number of convection units, thus overcoming the limitation that the efficiency of a single column will decrease as its size increases.

[0031] In summary, the modular convection device of this utility model can be equipped with multiple convection units in the shell, eliminating the need to increase the size of a single column. It only requires selecting shells with different numbers of convection units according to the production capacity requirements to perform component separation, achieving redundant design. It also facilitates seamless scaling up from pilot-scale to production scale, significantly shortening the scaling-up cycle and reducing verification costs.

[0032] 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.
