Description

Technical Field

[0001] This utility model relates to the field of catalyst preparation equipment, and in particular to a stirring and liquid addition device. Background Technology

[0002] In catalyst preparation, a certain amount of alkaline solution is typically added dropwise to a metal salt solution, causing the metal cations to form an insoluble precipitate, which is then washed and filtered to obtain the precursor. During this process, the rate of alkaline solution addition and the degree of mixing and contact between the alkaline solution and the metal cations significantly affect catalyst performance. Traditional processes involve continuously adding the alkaline solution in a container, with a stirring device accelerating the mixing of the alkaline solution and the metal cation solution. However, since the addition of the alkaline solution and the stirring are performed by different devices, a time lag inevitably exists, making it impossible to guarantee the continuity of operation and consequently affecting the performance of the product. Utility Model Content

[0005] A stirring and dispensing device, comprising:

[0006] The main component has a liquid inlet at its upper part;

[0007] Multiple blades are disposed at the lower part of the main pipe component. At least one drain port is provided on the surface of each blade, and a delivery channel is provided inside the blade to connect the inner cavity of the main pipe component with the drain port.

[0008] Preferably, the blades are detachably mounted on the main pipe.

[0009] Preferably, the blade includes an infusion tube and blades disposed on the infusion tube, the drain port is opened on the infusion tube, and the infusion channel is the inner cavity of the infusion tube.

[0010] Preferably, the number of drain ports on the infusion tube is multiple and they are distributed at intervals along the infusion tube.

[0011] Preferably, the drain outlet is located below the blade.

[0012] Preferably, the liquid inlet is the top opening of the main pipe.

[0013] Preferably, a filter screen is provided inside the main pipe below the liquid inlet.

[0014] The beneficial effects of this utility model are: This stirring and liquid adding device can add liquid into the main pipe component through the liquid adding port at the top of the main pipe component. The added liquid can flow into the liquid conveying channel along the main pipe component and then flow out from the liquid discharge port as the blade rotates. Thus, the liquid adding can be completed at the same time as stirring, ensuring that stirring and liquid adding are carried out synchronously, which can effectively improve the product performance, facilitate the liquid adding operation, and help improve production efficiency.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figure 1 and Figure 2 In a preferred embodiment of this utility model, a stirring and liquid-adding device includes: a main pipe 10, with a liquid inlet 11 at its upper part; and multiple blades disposed at the lower part of the main pipe 10, each blade having at least one drain outlet 23 on its surface, and a liquid delivery channel 211 within each blade connecting the inner cavity of the main pipe 10 to the drain outlet 23. This stirring and liquid-adding device allows liquid to be added to the main pipe 10 via the liquid inlet 11 at its upper part. The added liquid flows along the main pipe 10 into the liquid delivery channel 211 and then flows out from the drain outlet 23 as the blades rotate. This allows liquid addition to be completed simultaneously with stirring, ensuring synchronous stirring and liquid addition, effectively improving product performance, facilitating liquid addition operations, and contributing to increased production efficiency.

[0025] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0026] In this embodiment, the blades are detachably mounted on the main pipe component 10, which facilitates the separate manufacturing of the blades and the main pipe component 10, and allows for the replacement of different blades or main pipe components 10 as needed, making it more flexible and convenient to use. The blades can be mounted on the main pipe component 10 using common detachable structures such as screw connections or plug-in connections, which can be flexibly selected by those skilled in the art as needed.

[0027] In this embodiment, the blade includes an infusion tube 21 and a blade 22 disposed on the infusion tube 21. The drain port 23 is opened on the infusion tube 21. The infusion channel 211 is the inner cavity of the infusion tube 21. There is no need to open a hole in the thin blade 22, which is convenient for processing and manufacturing.

[0028] In this embodiment, the number of drainage ports 23 on the infusion tube 21 is multiple and they are distributed at intervals along the infusion tube 21, which helps to improve the drainage speed and the uniformity of drainage.

[0029] In this embodiment, the drain port 23 is located below the blade 22, which reduces the liquid flow into the drain port 23 when the blade 22 rotates, thus facilitating the smooth discharge of the injected liquid.

[0030] In this embodiment, the filling port 11 is the top opening of the main pipe component 10, which facilitates the filling operation and also makes it easy to connect to the injection equipment. In other embodiments, the filling port 11 may also be located at other suitable positions, such as the side of the upper part of the main pipe component 10, as needed.

[0031] In this embodiment, a filter screen 12 is provided inside the main pipe component 10 below the liquid inlet 11, which can prevent debris from entering the main pipe component 10 and causing blockage, making it more reliable.

[0032] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0033] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
