Description

Technical Field

[0001] The invention relates to the technical field of general cleaning dirt removal equipment, and in particular to a device for removing impurities from waste copper and waste aluminum materials. Background Art

[0002] During the resource recycling process, some metal materials generally need to be cleaned, shredded and cleaned again. The clean granular metal is then smelted in a furnace for recycling again.

[0003] However, since scrap copper and scrap aluminum are relatively soft compared to other metals, hard small parts such as pebbles or broken iron blocks may be stuck on their surface or joints after they are recycled. These harder small parts are generally difficult to clean during the cleaning process, and workers are often required to manually select them, which is relatively inefficient and has certain errors. Of course, some companies vibrate scrap copper or scrap aluminum to separate the hard blocks from the scrap copper or scrap aluminum. On the one hand, high-frequency vibration is required, which uses the collision of scrap aluminum or scrap copper with each other or with the inner wall of the vibrating component to remove the hard blocks. This requires a higher vibration frequency, and there is a certain ratio of collision between scrap copper or aluminum and the hard inner wall of the container, which causes the aluminum or copper to deform and wrap the hard blocks more tightly. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention provides a device for removing impurities from waste copper and waste aluminum.

[0005] The present invention provides a device for removing impurities from waste copper and waste aluminum, comprising a cleaning cylinder, a partition plate provided inside the cleaning cylinder, the partition plate separating the cleaning cylinder into an upper cleaning part and a lower circulation part, a liquid leakage port provided on the partition plate for flowing the liquid in the upper cleaning part to the lower circulation part, a liquid outlet provided on the lower circulation part, and an adjustable flow rate of the liquid outlet; specifically, an electromagnetic valve provided on the liquid outlet to adjust the flow rate of the liquid outlet;

[0006] A flushing column is provided in the middle of the cleaning cylinder, the flushing column is connected to a cleaning liquid through a pump, a flushing port is opened in the part of the flushing column located at the cleaning part, and the cleaning liquid in the flushing column is discharged from the flushing column;

[0007] The separation disk is provided with a stirring shaft, the outer diameter of which is smaller than the minimum size of the object to be cleaned, and also includes a driving member, which is used to drive the separation disk to rotate.

[0008] The total flow rate discharged from the flushing port of the flushing column and the flow rate ratio of the liquid outlet are adjustable. During the cleaning process, the cleaning liquid is discharged from the flushing port at a certain pressure to rotate the parts to be cleaned, and the separation plate rotates relative to the cleaning cylinder, thereby driving the parts to be cleaned in the cleaning liquid to rotate. During the cleaning process, the stirring shaft not only stirs the cleaning liquid but also collides with the parts to be cleaned to deform the parts to be cleaned, thereby detaching the hard blocks stuck in the cleaning parts. Under the action of centrifugal force, the cleaning parts generally face outward. In order to ensure a good effect, the separation plate is operated intermittently. In order to ensure the cleaning and impurity removal effect, the upper surface of the separation plate is a conical surface that gradually tilts upward from the middle to the outside, which realizes the impurity removal of granular impurities during the cleaning process and facilitates the granular materials to fall to the lower circulation part.

[0009] As a further optimized solution of the present invention, the inner wall of the cleaning cylinder is provided with a protective layer, and the hardness of the protective layer is not greater than the hardness of the object to be cleaned.

[0010] Preferably, in some embodiments, a plurality of protrusions are provided on the inner wall of the cleaning cylinder, the protrusions are arranged along the radial direction of the cleaning cylinder, and the outer diameter of the protrusions is smaller than the minimum size of the object to be cleaned.

[0011] In some embodiments, preferably, the protrusion includes a first protrusion and a second protrusion, the first protrusion and the second protrusion are spaced apart, and the length of the first protrusion is greater than the length of the second protrusion.

[0012] In some embodiments, preferably, the hardness of the second convex column and the hardness of the first convex column are both greater than the hardness of the object to be cleaned.

[0013] As a further optimized solution of the present invention, the stirring shaft is vertically rotatably mounted on the separation disk.

[0014] As a further optimized solution of the present invention, a transverse stirring rod is provided on the stirring shaft, and the outer diameter of the transverse stirring rod is smaller than the minimum size of the part to be cleaned.

[0015] As a further optimized solution of the present invention, there are multiple stirring shafts, and the multiple stirring shafts are distributed on the separation plate in a spiral shape.

[0016] Specifically, in some embodiments, an extension column is provided below the separation plate, and the extension column extends out of the mixing drum. The driving member drives the separation plate to rotate by driving the extension column to rotate.

[0017] In some embodiments, preferably, the separation plate is detachably mounted on the extension column, the separation plate can be taken out from above the cleaning cylinder, and a magnet is provided on the separation plate, so that iron-containing impurities can be adsorbed when the separation plate is taken out.

[0018] As a further optimized solution of the present invention, a through hole is opened in the extension column, and the lower half of the flushing column passes through the through hole.

[0019] In the present invention, the proposed impurity removal device for scrap copper and scrap aluminum increases work efficiency. During the cleaning process of scrap copper or scrap aluminum, the stirring shaft and the separation plate collide with the parts to be cleaned, thereby increasing the cleaning efficiency and also achieving the removal of impurities stuck on the outer wall of the scrap copper or scrap aluminum.
