[0027] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Figure 1 It is a schematic diagram of the overall structure of an acid preparation tank according to an embodiment of the present disclosure.

[0035] like Figure 1-Figure 3 As shown, the acid preparation tank of the present disclosure may include: a base assembly 1, a tank body assembly 2, a stirring mechanism 3 and other components.

[0036] Figure 2 It is a schematic structural diagram of a base assembly 1 and a tank assembly 2 of an acid preparation tank according to an embodiment of the present disclosure.

[0037] like Figure 2 As shown, in the present disclosure, the base assembly 1 includes a bottom plate 11, an ear plate 12 and a ladder 13, wherein four ear plates 12 are provided, and the four ear plates 12 are evenly fixed at the four corners of the top of the bottom plate 11, and the ladder 13 is fixed at the right side of the top of the bottom plate 11.

[0038] Therefore, the arrangement of the ear plate 12 enables the device to be moved in a suspended manner, and the arrangement of the ladder 13 facilitates the user to climb to the top of the acid preparation tank body 21 .

[0039] like Figure 2 As shown, in a preferred embodiment, the tank assembly 2 includes an acid preparation tank body 21, a guide plate 22, a liquid inlet pipe 23, a liquid outlet pipe 24 and a circulation tank 25, wherein the acid preparation tank body 21 is fixedly arranged on the top of the bottom plate 11, the guide plate 22 is fixedly arranged on the bottom of the inner cavity of the bottom plate 11, and the liquid inlet pipe 23, the liquid outlet pipe 24 and the circulation tank 25 are fixedly arranged in sequence from back to front through the bottom of the left side of the acid preparation tank body 21.

[0040] Therefore, the setting of the guide plate 22 can guide the acid liquid inside the acid preparation tank body 21, so that the acid liquid inside the acid preparation tank body 21 can be better output.

[0041] Figure 3 It is a schematic structural diagram of a stirring mechanism 3 of an acid preparation tank according to an embodiment of the present disclosure.

[0042] like Figure 3 As shown, in the present disclosure, the stirring mechanism 3 includes a fixed frame 31, a first rotating roller 32, a second rotating roller 33, a driving motor 34, a conveyor belt 35, a movable bar 36, a connecting belt 37, a stirring rod 38 and a fixed rod 39, wherein the first rotating roller 32 and the second rotating roller 33 are rotatably nested and arranged on the inner side of the fixed frame 31 from left to right in sequence through bearings, the driving motor 34 is fixedly arranged on the outer side of the fixed frame 31 and is transmission-connected with the second rotating roller 33, the conveyor belt 35 is sleeved and arranged on the outer side of the first rotating roller 32 and the second rotating roller 33, the movable bar 36 is rotationally connected to the outer side of the conveyor belt 35 through a hinge, the connecting belt 37 is fixedly connected between the movable bar 36 and the stirring rod 38, and the fixed rod 39 is fixedly connected between the acid preparation tank body 21 and the fixed frame 31.

[0043] It should also be noted that the exterior of each component in the stirring mechanism 3 is provided with a corrosion-resistant coating or is made of corrosion-resistant raw materials, thereby avoiding damage due to acid corrosion during use.

[0044] Thus, the driving motor 34 drives the second rotating roller 33 to rotate, and the second rotating roller 33 cooperates with the first rotating roller 32 to drive the conveyor belt 35 to rotate continuously. When the conveyor belt 35 rotates, it drives the multiple movable bars 36 to move synchronously. In this process, the multiple connecting belts 37 on the lower movable bar 36 droop into the acid liquid under the action of gravity and continue to stir the acid liquid during the movement, and the multiple connecting belts 37 of the upper movable bar 36 are attached to the top of the conveyor belt 35 under the action of gravity, thereby reducing the space occupied.

[0045] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.
