Description

Technical Field

[0001] This utility model belongs to the field of waste aluminum recycling and reprocessing technology, and in particular relates to an aluminum liquid filtration device. Background Technology

[0002] Aluminum molten aluminum filtration technology primarily removes impurities from the molten aluminum using physical methods. Common filtration methods include ceramic foam filtration, glass fiber filtration, and deep-bed filtration. Ceramic foam filters are widely used in aluminum molten aluminum purification processes due to their high porosity and excellent high-temperature resistance. This type of filter effectively captures fine particles, significantly reducing porosity and inclusion defects in castings. Glass fiber filters are mostly used in the primary filtration stage; they are low-cost, easy to replace, and suitable for mass production. Deep-bed filtration uses multiple layers of filter media and can handle aluminum molten aluminum with high impurity content, but its maintenance costs are relatively high.

[0003] Comparing with Chinese Patent No. CN222324482U, a waste aluminum recycling aluminum liquid filtration device is disclosed, including an aluminum liquid collection tank, a filter assembly above the aluminum liquid collection tank, and a flipping assembly on the side of the filter assembly. During use, the waste aluminum liquid flowing into the filter shell is filtered by the filter screen plate, blocking most of the insoluble impurities in the waste aluminum liquid. At the same time, the vibration motor drives the filter screen plate to vibrate through the heat insulation support frame, support plate and filter shell. At this time, the impurities blocked by the filter screen plate will slide and accumulate to the left and right sides, avoiding the accumulation of waste residue in the middle of the filter screen plate and affecting its filtration smoothness, thereby improving the filtration efficiency of the filter screen plate. When the low-speed motor drives the filter shell to flip forward 90 degrees through the transmission worm, transmission worm wheel and active support shaft, the waste residue blocked by the filter screen plate can fall downward into the waste residue collection box, thereby facilitating the cleaning of the waste residue.

[0004] However, the aforementioned patent requires stopping the machine to clean impurities after each filtration of molten aluminum, which cannot achieve efficient filtration and continuous production of molten aluminum. Therefore, a new type of equipment needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum liquid filtration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aluminum molten metal filtration device includes a frame assembly for tilting and supporting the inlet and outlet of the aluminum molten metal, and a rotary screen assembly for continuously filtering impurities, installed in the middle of the frame assembly. Two vibration components for rotating and striking vibration are symmetrically installed on the top of the frame assembly. The rotary screen assembly includes a filter cylinder, which is a cylindrical shape with both ends open. The two ends of the filter cylinder are respectively set as an inlet and an outlet, with the inlet higher than the outlet. A power mechanism is provided at the end of the filter cylinder near the inlet. The vibration components include a fixed base, with a second motor installed at one end of the fixed base. A drive shaft is installed at the output end of the second motor, and two striking mechanisms are evenly installed on the drive shaft.

[0008] Furthermore: the frame assembly includes a base support, a first support is inclinedly arranged on the base support, a liquid outlet hopper is inclinedly arranged below the first support, a second support is arranged on the side of the first support near the feed inlet, a feed hopper is arranged on the top of the second support, and the feed hopper passes through the feed inlet into the filter screen cylinder.

[0009] Furthermore: a support bearing is installed in the middle of the first bracket, and the second bracket is welded together with the first bracket.

[0010] Furthermore: the power mechanism includes a passive gear ring fixedly installed around the circumference of the filter screen cylinder, a drive gear meshing below the passive gear ring, and the drive gear fixedly installed on the output end of the first motor.

[0011] Furthermore: the diameter of the discharge port is equal to the inner diameter of the filter cylinder, and the diameter of the inlet is smaller than the inner diameter of the filter cylinder.

[0012] Furthermore, the striking mechanism includes a connecting sleeve, on which several spring plates are evenly distributed around the circumference, and a striking head is installed at the end of each spring plate.

[0013] Furthermore, the striking head is cylindrical and is bolted to the spring plate.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. Through the synergistic effect of rotary screening, mechanical vibration and inclined self-discharge, rotary filtration and vibration slag discharge are carried out simultaneously without the need for machine shutdown for cleaning, realizing efficient filtration, anti-clogging and continuous production of aluminum liquid. It has both structural reliability and maintenance convenience, and is suitable for industrial aluminum processing scenarios.

[0016] 2. During the rotation process, the molten aluminum and impurities naturally separate due to the difference in gravity. The impurities slide along the inclined bottom of the cylinder to the discharge port, avoiding the local clogging problem of static filtration. The molten aluminum flows naturally by gravity, reducing pumping energy consumption. The filtered molten aluminum is guided through the discharge hopper without the need for additional power.

[0017] 3. The symmetrically distributed vibration components periodically strike the mesh cylinder through the striking head at the end of the spring plate driven by the motor, generating high-frequency vibration, which effectively prevents fine impurities from adhering; the symmetrical layout of the dual vibration components cancels out eccentric vibration, reduces equipment operating vibration noise, and extends bearing life.

[0028] In this embodiment: the rotary screen assembly includes a filter cylinder 201, which is a cylindrical shape with both ends open. The two ends of the filter cylinder 201 are respectively set as an inlet 202 and an outlet 203, with the inlet 202 higher than the outlet 203. A power mechanism is provided at one end of the filter cylinder 201 near the inlet 202. The power mechanism includes a passive gear ring 204 fixedly mounted around the circumference of the filter cylinder 201, and a drive gear 205 meshing below the passive gear ring 204. The drive gear 205 is fixedly mounted on the output end of the first motor 206. The diameter of the outlet 203 is equal to the diameter of the filter cylinder 201. The inner diameter of the filter cylinder 201 is smaller than the diameter of the feed inlet 202. The molten aluminum enters the filter cylinder 201 through the feed inlet 202. At the same time, the first motor 206 drives the active gear 205 to mesh with the passive gear ring 204 to rotate, which drives the filter cylinder 201 to rotate under the support of the bearing 103 in the first bracket 102. This causes the molten aluminum to rotate and be screened along the inner wall of the filter cylinder 201. The filtered molten aluminum passes through the filter cylinder 201 and falls onto the liquid outlet 106 to flow out. Impurities flow down the bottom of the filter cylinder 201 at an angle and are discharged from the discharge outlet 203.

[0029] In this embodiment: the vibration component includes a fixed base 301, a second motor 302 is mounted on one end of the fixed base 301, a transmission shaft 303 is mounted on the output end of the second motor 302, and two striking mechanisms are evenly mounted on the transmission shaft 303; the striking mechanism includes a connecting sleeve 304, a plurality of spring plates 305 are evenly distributed around the circumference of the connecting sleeve 304, and a striking head 306 is mounted on the end of the spring plate 305; the striking head 306 is cylindrical and bolted to the spring plate 305; the fixed base 301 supports the second motor 302 to drive the connecting sleeve 304 to rotate through the transmission shaft 303, thereby driving the spring plate 305 to rotate, and the striking head 306 strikes the filter cylinder 201 to generate vibration, thereby preventing impurities from adhering to the filter cylinder 201 and ensuring that impurities are smoothly discharged.

The second support 104 tilts and supports the feed hopper 105, allowing the molten aluminum to enter the filter cylinder 201 from the feed inlet 202. At the same time, the first motor 206 drives the active gear 205 to mesh with the passive gear ring 204 to rotate, causing the filter cylinder 201 to rotate under the support of the bearing 103 in the first support 102. This causes the molten aluminum to rotate and be screened along the inner wall of the filter cylinder 201. The filtered molten aluminum passes through the filter cylinder 201 and falls onto the outlet hopper 106 to flow out. Impurities flow down the bottom of the filter cylinder 201 at an angle and are discharged from the outlet 203. The fixed seat 301 supports the second motor 302, which drives the connecting sleeve 304 to rotate through the transmission shaft 303. This drives the spring plate 305 to rotate, and the striking head 306 strikes the filter cylinder 201 to generate vibration, preventing impurities from adhering to the filter cylinder 201 and ensuring smooth discharge of impurities.
