Description

Technical Field

[0001] This utility model relates to a zinc powder anti-settling filtration device. Background Technology

[0002] Currently, in industrial production processes involving zinc powder, such as coatings, batteries, and chemicals, zinc powder, due to its unique physical and chemical properties, is prone to sedimentation in liquid systems. Zinc powder sedimentation not only affects product uniformity and quality but also complicates subsequent filtration operations, leading to reduced filtration efficiency, increased filtration costs, and unstable product quality. Therefore, there is a need for equipment that can simultaneously prevent zinc powder sedimentation and achieve efficient filtration to meet the demands of industrial production. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a zinc powder anti-settling filtration device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a zinc powder anti-settling filtration device, comprising a container and a stirring assembly, wherein the stirring assembly comprises a rotating shaft rotatably disposed within the container, a stirring disc fixed at the lower part of the rotating shaft, and a stirring paddle fixed at the upper part of the rotating shaft, the stirring disc comprising a disc and upper and lower blades spaced apart around the periphery of the disc, the disc having multiple perforations spaced around its axis, and a flow guide plate inclined along the rotation direction at the perforations on the lower surface of the disc, wherein a filter port is provided at the bottom or side of the container, and the filter port is connected to the filtration assembly.

[0005] A further improvement is made by staggering the upper and lower blades.

[0006] In a further improvement, the upper blade includes an upper extension extending outward from the periphery of the disk and an upper bent portion bending upward from the outer end of the upper extension; the lower blade includes a lower extension extending outward from the periphery of the disk and a lower bent portion bending downward from the outer end of the lower extension; the upper extension and the lower extension have a triangular structure.

[0007] In a further improvement, the cutout is triangular.

[0008] Further improvements were made, with the upper blade being longer than the lower blade.

[0009] In a further improvement, the impeller includes a hub disposed on and coaxially with the rotating shaft and at least three blades disposed around the hub, wherein the angle between the blades and the axis of the rotating shaft is 30° to 60°.

[0010] In a further improvement, the distance between the mixing disc and the mixing blade is 50% to 80% of the working radius of the mixing disc, and the ratio of the working radius of the mixing disc to the working radius of the mixing blade is 1:0.6 to 0.7.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This utility model, through its set stirring plate and stirring paddle, can fully stir liquid containing zinc powder, preventing the zinc powder from settling and clumping; the design of the hollow and guide plate on the stirring plate can guide the specific flow direction of the liquid, enhancing the dispersion of zinc powder and facilitating subsequent filtration operations; furthermore, the staggered arrangement of the upper and lower blades can form a more complex fluid flow during stirring, enhancing the suspension and dispersion effect of zinc powder, preventing zinc powder from settling in local areas, and improving stirring efficiency; furthermore, the upper and lower blades each have triangular extensions, forming a certain angle between the upper and lower blades and the periphery of the disc, which can enhance the shear force on the liquid and further prevent zinc powder from settling; furthermore, the upper blade is longer than the lower blade, which can form an asymmetrical fluid flow during stirring, enhancing the suspension and dispersion effect of zinc powder; furthermore, the distance between the stirring plate and the stirring paddle, as well as the ratio of the working radius of the stirring plate to the stirring paddle, are optimized to ensure a reasonable flow velocity gradient within the stirring area, enhancing the suspension and dispersion effect of zinc powder.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-3This embodiment provides a zinc powder anti-settling filtration device, including a container 1 and a stirring assembly. The stirring assembly includes a rotating shaft 2 rotatably disposed within the container 1, a stirring disc fixed to the lower part of the rotating shaft 2, and a stirring paddle fixed to the upper part of the rotating shaft 2. The container 1 has a filter port (not shown in the figure) at its bottom or side, and the filter port is connected to a filter assembly (not shown in the figure). The distance between the stirring disc and the stirring paddle is 50% to 80% of the working radius of the stirring disc, and the ratio of the working radius of the stirring disc to the working radius of the stirring paddle is 1:0.6 to 0.7. This utility model can fully stir the liquid containing zinc powder by setting the stirring disc and the stirring paddle, preventing the zinc powder from settling and clumping. At the same time, the distance between the stirring disc and the stirring paddle and the ratio of the working radii of the stirring disc and the stirring paddle are optimized to ensure a reasonable flow velocity gradient in the stirring area and enhance the suspension and dispersion effect of the zinc powder.

[0019] Specifically, in this embodiment, the stirring disc includes a disc 31 and upper blades 32 and lower blades 33 spaced apart around the periphery of the disc 31. The upper blades 32 and lower blades 33 are staggered, and the length of the upper blade 32 is greater than the length of the lower blade 33. The upper blade 32 includes an upper extension portion 321 extending outward from the periphery of the disc 31 and an upper bent portion 322 bending upward from the outer end of the upper extension portion 321. The lower blade 33 includes a lower extension portion 331 extending outward from the periphery of the disc 31 and a lower bent portion 332 bending downward from the outer end of the lower extension portion 331. The upper extension portion 321 and the lower extension portion 331 have a triangular structure.

[0020] In this embodiment, the disc 31 is provided with a plurality of hollows 34 spaced around its axis. A flow guide plate 35 is inclined at the hollows 34 along the rotation direction on the lower surface of the disc 31. The hollows 34 are triangular. The design of the hollows 34 and the flow guide plate 35 can guide the liquid to flow in a specific direction, enhance the dispersion of zinc powder, and provide convenience for subsequent filtration operations.

[0021] In this embodiment, the stirring paddle includes a hub 41 disposed on and coaxially disposed with the rotating shaft 2 and at least three blades 42 disposed around the hub 41, wherein the angle between the blades 42 and the axis of the rotating shaft 2 is 30° to 60°.
