Description

Technical Field

[0001] The present application relates to the field of aluminum product production equipment, and in particular to an aluminum water fine filter. Background Art

[0002] Aluminum molten fine filter is a new type of filtering equipment used for solid-liquid separation in the alumina production process. Solid aluminum is heated at high temperature to become aluminum molten. Since aluminum molten contains impurities, in order to reduce the impact of impurities on the quality of aluminum products, aluminum molten needs to be filtered. Usually, aluminum molten fine filter is used to filter aluminum molten to improve its quality.

[0003] The existing aluminum water fine filter adopts a single filtration method, so that the purity of the aluminum water after filtration is not high, and the impurities in the aluminum water are accumulated on the filter device, reducing the effective filtration area of ​​the filter device, thereby reducing the filtration efficiency of the aluminum water.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing aluminum water fine filter has the problems of low purity of the aluminum water after filtration and low filtration efficiency. Utility Model Content

[0005] In order to solve the problems of low purity and low filtration efficiency of molten aluminum after filtration in the existing molten aluminum fine filter, the present application provides a molten aluminum fine filter.

[0006] The present application provides an aluminum water fine filter, which adopts the following technical solution:

[0007] A molten aluminum fine filter comprises a base, a box body arranged on the base, a filtering mechanism arranged in the box body, a height adjustment mechanism connected to the filtering mechanism and a sedimentation tank opened on the base; the box body is communicated with the sedimentation tank, a feed pipe is arranged on a side of the box body away from the base, the feed pipe is communicated with the box body, an observation window is opened on the side wall of the box body, the filtering mechanism comprises a filter housing arranged below the feed pipe, a first filter plate and a second filter plate arranged in the filter housing, a liquid outlet is opened on the base, the liquid outlet is communicated with the sedimentation tank, and the liquid outlet is arranged at one end of the base away from the bottom of the sedimentation tank.

[0008] By adopting the above technical solution, the molten aluminum falls into the filter mechanism through the feed pipe, and the molten aluminum is double filtered through the first filter plate and the second filter plate, which improves the filtering effect and reduces the phenomenon that impurities accumulate on one filter plate, thereby reducing the filtering efficiency. The molten aluminum that passes through the filtering mechanism falls into the sedimentation tank, and the impurities in the molten aluminum settle to the bottom of the sedimentation tank. The molten aluminum with less impurities flows out of the base from the liquid outlet far away from the bottom of the sedimentation tank. The height adjustment mechanism can adjust the height of the filtering mechanism, thereby reducing the distance between the filtering mechanism and the liquid surface of the molten aluminum in the sedimentation tank, thereby reducing the disturbance of the molten aluminum in the sedimentation tank when the molten aluminum falls into the sedimentation tank, thereby facilitating the precipitation of impurities in the molten aluminum in the sedimentation tank. By setting two filtering treatments and one precipitation treatment, the filtering effect of the molten aluminum is improved, and the filtering efficiency is improved.

[0009] Optionally, a slide groove is provided on the side wall of the box body, and the height adjustment mechanism includes a transmission motor fixedly connected to the box body, a screw rod and a slider arranged in the slide groove; one end of the screw rod is fixedly connected to the transmission shaft of the transmission motor, and the other end is rotatably connected to the box body, the slider is slidably connected to the slide groove, the slider is threadedly connected to the screw rod, and is fixedly connected to the filter housing.

[0010] By adopting the above technical solution, the transmission motor drives the lead screw to rotate, the lead screw drives the slider to slide in the slide groove, and the slider drives the filter housing to move up and down, thereby adjusting the distance between the filter mechanism and the aluminum liquid level in the sedimentation tank, thereby reducing the influence of the falling aluminum liquid on the impurity sedimentation process, thereby improving the impurity sedimentation effect and improving the purity of the aluminum liquid.

[0011] Optionally, a guide funnel is connected to one end of the filter housing away from the feed pipe.

[0012] By adopting the above technical solution, the setting of the guide funnel allows the molten aluminum to slowly flow out of the filtering mechanism after filtration is completed, reducing the impact of the falling molten aluminum on the sedimentation effect, thereby further improving the effect of impurity sedimentation and further improving the purity of the molten aluminum.

[0013] Optionally, a plurality of first filter holes are formed on the first filter plate, a plurality of second filter holes are formed on the second filter plate, and the aperture of the first filter holes is larger than the aperture of the second filter holes.

[0014] By adopting the above technical solution, the first filter plate filters the impurities with larger particle sizes in the aluminum water, and the second filter plate filters the impurities with smaller particle sizes in the aluminum water, thereby reducing the resistance of the two filtrations, improving the efficiency of the two filtrations, and improving the filtering effect on the aluminum water.

[0015] Optionally, the liquid outlet is arranged on a side of the base away from the filtering mechanism, and a sedimentation slope is arranged on a side of the sedimentation tank close to the liquid outlet.

[0016] By adopting the above technical solution, the outlet is far away from the filtering mechanism, which reduces the disturbance of the aluminum liquid flowing out of the base, increases the sedimentation time, and improves the sedimentation effect. The sedimentation slope allows the impurities that settle to the bottom of the sedimentation tank to slide to the side away from the outlet, thereby improving the separation effect of aluminum liquid and the settled impurities, thereby improving the filtering effect of aluminum liquid and improving the purity of aluminum liquid.

[0017] Optionally, a third filter plate is provided on the sedimentation slope, a plurality of third filter holes are formed on the third filter plate, and the aperture of the third filter holes is smaller than the aperture of the second filter holes.

[0018] By adopting the above technical solution, the third filter plate removes impurities remaining in the molten aluminum, further increasing the purity of the molten aluminum, and the third filter plate blocks impurities that settle to the bottom of the sedimentation tank, thereby further improving the separation effect of the molten aluminum and the settled impurities.

[0019] Optionally, a drain pipe is connected to one end of the side wall of the base close to the bottom of the sedimentation tank, the drain pipe is communicated with the sedimentation tank, and a valve is provided on the drain pipe.

[0020] By adopting the above technical solution, when no molten aluminum that needs to be filtered enters the box, the valve can be opened to discharge the molten aluminum in the sedimentation tank, reducing the possibility of the molten aluminum cooling and solidifying in the sedimentation tank and reducing the waste of molten aluminum.

[0021] Optionally, a filter screen is arranged inside the drain pipe.

[0022] By adopting the above technical solution, when discharging molten aluminum, the filter screen intercepts the settled impurities, thereby improving the separation effect of the molten aluminum and the settled impurities.

[0023] Optionally, the box and the base are detachably connected.

[0024] By adopting the above technical solution, the box body is separated from the base after the aluminum liquid is discharged, which makes it convenient for the staff to clean up the settled impurities and facilitate the subsequent aluminum liquid treatment.

[0025] Optionally, a guide plate is provided in the liquid outlet, and the guide plate is inclined.

[0026] By adopting the above technical solution, the molten aluminum enters the subsequent processing device through the guide plate, and the inclined guide plate increases the outflow rate of the molten aluminum, thereby improving the processing efficiency of the molten aluminum.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The filtering mechanism performs two filtration treatments on the aluminum liquid, which improves the filtering effect and efficiency. The aluminum liquid settles impurities in the sedimentation tank, so that the remaining impurities are separated from the aluminum liquid, which improves the purity of the aluminum liquid;

[0029] 2. The height adjustment mechanism adjusts the height of the filtering mechanism, reducing the disturbance of the falling aluminum liquid to the aluminum liquid in the sedimentation tank, thereby improving the effect of impurity sedimentation. The diversion funnel slows down the falling speed of the aluminum liquid, thereby further improving the effect of impurity sedimentation;

[0030] 3. The setting of the sedimentation slope and the third filter plate increases the separation effect of the sedimentation impurities and the aluminum liquid, thereby further improving the purity of the aluminum liquid. BRIEF DESCRIPTION OF THE DRAWINGS
