Description

Technical Field

[0001] The utility model relates to the technical field of screening and impurity removal of waste aluminum raw materials, in particular to a screening and impurity removal device for waste aluminum raw materials. Background Art

[0002] Aluminum is a white light metal with ductility. The product is often made into rods, sheets, foils, powders, strips and filaments. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions. When recycling and reusing waste aluminum, it only needs to be heated to the melting point for melting. However, before melting it, a screening and impurity removal device is needed to screen and remove impurities from the crushed waste aluminum raw materials to avoid a large amount of impurities in the waste aluminum raw materials when they are melted.

[0003] Publication No. "CN214077756U" provides a device for screening and removing impurities from scrap aluminum raw materials. The inner cavity of the carrying box is provided with an inclined filter screen. The shaking of the filter screen can screen out dust and soil particles in the scrap aluminum. Multiple nozzles arranged at the bottom of the door panel can spray water to prevent dust from shaking and splashing to pollute the air. The water flow can clean the scrap aluminum, which can improve its screening efficiency.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] First of all, the scrap aluminum raw material screening and impurity removal device can only wash and screen the scrap aluminum raw materials, and cannot remove iron impurities in the scrap aluminum raw materials. Since the melting point of iron is higher than that of aluminum, the scrap aluminum raw materials mixed with iron impurities will affect the purity of the scrap aluminum melting and recovery. Secondly, the scrap aluminum raw material screening and impurity removal device cannot pre-dry the scrap aluminum raw materials after washing and screening, resulting in the scrap aluminum raw materials after washing and screening being relatively moist. At this time, the staff is required to transfer the moist scrap aluminum raw materials to the drying equipment for drying before the melting operation can be carried out, which affects the efficiency of scrap aluminum recovery. The practicality needs to be improved. Utility Model Content

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, the driving motor 31 drives the conveyor belt 37 to rotate through the transmission roller 34, so that the rotating conveyor belt 37 can transport the right side of the scrap aluminum raw material guided down from the feeding hopper 1 to the screening mesh plate 67. In this process, the permanent magnetic roller 38 will adsorb the iron debris in the scrap aluminum raw material transported to the right side through the conveyor belt 37 to prevent the iron debris from being transported to the screening mesh plate 67 along with the scrap aluminum raw material. Then, the adsorbed iron debris will be scraped off by the silicone rubber scraper strip 36 and guided into the iron debris collection box 33 through the guide plate 32, so as to remove iron from the scrap aluminum raw material.

[0034] The iron removal component 3 includes a driving motor 31, a guide plate 32, an iron chip collection box 33, a transmission roller 34, a support bar 35, a silicone rubber scraper strip 36, a conveyor belt 37 and a permanent magnetic roller 38.

[0036] Working principle: In the process of screening and removing impurities from the crushed waste aluminum raw materials, the staff first starts the driving motor 31, so that the driving motor 31 drives the conveyor belt 37 to rotate clockwise through the transmission roller 34, and then starts the vibration motor 64, so that the vibration motor 64 drives the sorting box 2 to vibrate, and the sorting box 2 will drive the screening mesh plate 67 to vibrate together through the supporting partition 65 and the supporting seat 66, and then open the water supply valve 622 and start the submersible pump 615, so that the submersible pump 615 transfers the water in the water storage barrel 62 to the diverter shell 69 through the water pipe 614.
