It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0036] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0037] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0038] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "below," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "below" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0039] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0048] Therefore, by setting the limiting ring 15, the limiting ring 15 can effectively limit the clamping ring 31, and by setting the sealing rubber gasket 32, the sealing rubber gasket 32 ​​can effectively increase the sealing between the connecting plate 3 and the horizontal filter box body 1 to avoid solution leakage, and by setting the fastening bolts 6, the connecting plate 3 can be effectively fixed to one side of the horizontal filter box body 1, thereby improving the fixing effect.

[0049] like Figure 2 As shown, in the present disclosure, the clamping assembly includes a mounting plate 4 , a rotating ring 41 is disposed on the inner side of the mounting plate 4 , and the filter barrel 5 is rotatably disposed on the inner side of the rotating ring 41 .

[0050] Therefore, the end of the filter barrel 5 is arranged on the inner side of the rotating ring 41, which effectively increases the stability and lubricity of the rotation, making it easier for the filter barrel 5 to rotate and complete subsequent filtering work.

A cross-shaped slot 531 is provided on the inner side of the fixed block 53, and the cross-shaped slot 531 and the cross-shaped block 22 are provided corresponding to each other.

[0052] Therefore, by setting the connecting rod 54, the fixed block 53 can be effectively fixed to the inner side of the filter barrel 5, and by setting the feed trough 52, the solution can flow from the feed port 13 into the feed trough 52 and into the inner side of the filter barrel 5 for filtering. By setting a cross-shaped card groove 531 on the inner side of the fixed block 53, the cross-shaped card groove 531 is correspondingly connected with the cross-shaped card block 22. When the cross-shaped card block 22 rotates, it can effectively drive the fixed block 53 to rotate, thereby driving the filter barrel 5 to rotate, and then completing the subsequent filtering work.
