Description

Technical Field

[0001] This utility model relates to the field of copper and aluminum sorting technology, specifically a copper and aluminum sorting device with magnetic impurity pre-removal function. Background Technology

[0002] In the scrap metal recycling industry, copper and aluminum are commonly used non-ferrous metals, and their recycling and reuse have extremely high economic value and environmental significance. However, the actual recycled metal scrap has a complex composition, often mixed with magnetic impurities such as iron nails, iron filings, and magnetic alloys, in addition to copper and aluminum. Existing copper-aluminum separation equipment mostly adopts a single gravity separation or airflow separation structure, without a dedicated magnetic impurity pretreatment mechanism. During the separation process, magnetic impurities easily adhere to the surface of the separation components, which not only interferes with the stability of the airflow field and the gravity separation trajectory, leading to a decrease in copper-aluminum separation accuracy, but may also cause wear and blockage of internal components, reducing the service life of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a copper-aluminum sorting device with a magnetic impurity pre-removal function, which has the advantage of being able to pre-remove magnetic impurities.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a copper-aluminum sorting device with magnetic impurity pre-removal function, comprising a sorting box, a drive motor mounted on the back of the sorting box, the output shaft of the drive motor penetrating into the interior of the sorting box to install a magnetic roller, a feed hopper fixedly mounted on the upper left side of the sorting box, the lower end of the feed hopper extending into the interior of the sorting box and located above the magnetic roller, an impurity collection box being pulled out and installed on the left side of the bottom of the sorting box cavity, the impurity collection box corresponding to the lower part of the magnetic roller, an inclined airflow distribution plate mounted on the right side of the magnetic roller, a vertical plate mounted on the right end of the airflow distribution plate, the lower end of the vertical plate being connected to the bottom of the sorting box cavity, an air duct mounted obliquely above the airflow distribution plate, the upper end of the air duct extending to the top of the sorting box and connected to a high-pressure blower, and a material collection box mounted on the right side of the bottom of the sorting box cavity.

A guide rod is vertically slidably installed on the left side inside the lower end of the scraper, and the bottom of the guide rod is installed to the bottom of the inner cavity of the sorting box.

[0007] As a preferred embodiment, the inside of the feed hopper is equipped with partition plates at equal intervals, and the multiple partition plates divide the inside of the feed hopper into multiple spaces.

[0008] As a preferred embodiment, a second baffle plate is installed on the right side of the inner cavity of the sorting box. The lower end of the second baffle plate extends obliquely to the top of the material collection box, and the second baffle plate corresponds to the right end of the airflow distribution plate.

[0009] As a preferred embodiment, fixed seats are installed on both the front and rear sides of the right end of the sorting box.

[0010] As a preferred embodiment, an adjusting plate is installed at the front end of the sealing baffle, and a locking knob is installed inside the adjusting plate with a through thread. The locking end of the locking knob is fastened to the outside of the sorting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

It eliminates the need for secondary impurity removal, reduces recycling costs, and improves production efficiency.

[0012] 2. This utility model uses a first baffle plate to shield the magnetic impurities after adsorption through an inclined guide, ensuring that the magnetic impurities on the surface of the magnetic roller will not disperse to other places during rotation; the scraper, together with the symmetrically arranged support springs at the bottom, can ensure that the scraper is always in close contact with the surface of the magnetic roller through the continuous elastic force of the springs.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0017] Please see Figure 1 As shown, this utility model provides a copper-aluminum sorting device with magnetic impurity pre-removal function, including a sorting box 1. A drive motor 2 is installed on the back of the sorting box 1. The output shaft of the drive motor 2 passes through the interior of the sorting box 1 and a magnetic roller 3 is installed thereon. A feed hopper 6 is fixedly installed on the upper left side of the sorting box 1. The lower end of the feed hopper 6 extends into the interior of the sorting box 1 and is located above the magnetic roller 3. An impurity collection box 4 is pulled out and installed on the left side of the bottom of the inner cavity of the sorting box 1. The impurity collection box 4 is located below the magnetic roller 3. An inclined airflow distribution plate 11 is installed on the right side of the magnetic roller 3. A vertical plate 12 is installed on the right end of the airflow distribution plate 11. The lower end of the vertical plate 12 is connected to the bottom of the inner cavity of the sorting box 1. An air duct 13 is installed diagonally above the airflow distribution plate 11. The upper end of the air duct 13 extends to the top of the sorting box 1 and is connected to a high-pressure blower 14. A material collection box 15 is installed on the right side of the bottom of the inner cavity of the sorting box 1.

[0018] This technical solution incorporates a magnetic roller 3, which adsorbs and removes magnetic impurities from the copper-aluminum mixture before copper-aluminum separation. This prevents magnetic impurities from entering subsequent separation stages, effectively preventing wear and blockage of key components of the separation equipment. It also improves the purity of copper-aluminum separation, eliminates the need for secondary impurity removal, reduces recycling costs, and increases production efficiency. Example

[0019] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a first baffle plate 5 is installed at the bottom of the feed hopper 6, and the lower end of the first baffle plate 5 extends obliquely to the top of the impurity collection box 4; a scraper 8 is attached to the lower right of the magnetic roller 3, and a support spring 9 is symmetrically installed at the bottom of the scraper 8. The lower end of the support spring 9 is connected to the bottom of the inner cavity of the sorting box 1. A guide rod 10 is vertically slidably installed on the left side inside the lower end of the scraper 8, and the bottom of the guide rod 10 is installed with the bottom of the inner cavity of the sorting box 1.

[0020] Adopting such Figure 1 The technical solution shown has a first baffle plate 5 that can shield the magnetic impurities after adsorption by tilting and guiding, ensuring that the magnetic impurities on the surface of the magnetic roller 3 will not disperse to other places when rotating; the scraper 8, together with the support springs symmetrically arranged at the bottom, can ensure that the scraper 8 is always in close contact with the surface of the magnetic roller 3 through the continuous elastic force of the spring. No matter if the roller is slightly worn due to long-term use, or if there are a few large particles of impurities in the material that cause the scraper 8 to temporarily shift, the spring can quickly reset the scraper 8, ensuring the stability of the scraping effect and preventing magnetic impurities from remaining on the surface of the roller due to the scraper 8 not being in close contact, thus affecting the subsequent adsorption effect.

[0021] Secondly, in the technical solution, partition plates 7 are installed at equal intervals inside the feed hopper 6, and multiple partition plates 7 divide the inside of the feed hopper 6 into multiple spaces; a second baffle plate 16 is installed on the right side of the inner cavity of the sorting box 1, and the lower end of the second baffle plate 16 extends obliquely to the top of the material collection box 15, and the second baffle plate 16 corresponds to the right end of the airflow distribution plate 11.

[0022] Its adoption is as follows Figure 1 According to the technical solution shown, when the copper-aluminum mixture is fed into the feed hopper 6, the partition plate 7 can prevent the material from accumulating and clogging at the feed inlet, and evenly distribute the material to multiple channels, ensuring that the material falls onto the surface of the magnetic roller 3 with a stable and uniform flow rate, reducing the agglomeration of large pieces of material, making the material particles more dispersed, further improving the accuracy of subsequent magnetic adsorption and copper-aluminum separation, and reducing the separation error caused by material agglomeration. After being separated by airflow, copper and aluminum particles slide down from the right end of the airflow distribution plate 11. Due to inertia, they may bounce against the inner wall of the sorting box 1, causing the separated copper and aluminum particles to mix again. The second baffle plate 16 can buffer and guide the sliding particles through its tilt angle design, stably guiding the copper and aluminum particles to the corresponding area in the material collection box 15, avoiding particle bounce and mixing, and ensuring the final purity of copper and aluminum separation. Example

[0023] This utility model is as follows Figures 1-4As shown, a fixed seat 17 is installed on both the front and rear sides of the right end of the sorting box 1. A sealing baffle 18 is installed inside the fixed seat 17 through the cooperation of the sliding groove and the slider. The left side of the sealing baffle 18 is in contact with the right side of the material collection box 15. An upper discharge groove is opened on the right side of the sealing baffle 18. An adjusting plate 19 is installed at the front end of the sealing baffle 18. A locking knob 20 is installed inside the adjusting plate 19 through the thread. The locking end of the locking knob 20 is fastened to the outside of the sorting box 1.

[0024] Using the above technical solution, the left side of the sealing baffle 18 is tightly fitted to the right side of the material collection box 15, which can effectively block the airflow between the inside of the sorting box 1 and the outside, prevent the sorting airflow generated by the high-pressure blower 14 from leaking out, and also block and limit the right side of the material collection box 15 through the sealing baffle 18. When it is necessary to remove or put into the material collection box 15, simply loosen the locking knob 20 and push the adjusting plate 19 to drive the sealing baffle 18 to slide up and down along the groove of the fixed seat 17, easily realizing the opening and closing of the baffle. The operation steps are simple and do not require complicated tools, greatly improving the efficiency of material replacement.

[0025] The working principle of this utility model is as follows: First, the drive motor 2 and the high-pressure blower 14 are started. The drive motor 2 drives the magnetic roller 3 to rotate counterclockwise. The high-pressure blower 14 generates a high-pressure airflow and blows it onto the surface of the airflow distribution plate 11 through the air duct 13. Then, the copper-aluminum mixture to be sorted is fed into the feed hopper 6. The separator 7 in the feed hopper 6 divides the material into multiple streams to avoid material accumulation. The material falls evenly onto the surface of the rotating magnetic roller 3. The magnetic roller 3 adsorbs magnetic impurities in the material. As the magnetic roller 3 rotates, the magnetic impurities adsorbed on its surface are scraped off by the scraper 8. Then, the copper-aluminum mixture falls into the impurity collection box 4 below to pre-remove magnetic impurities. After removing the magnetic impurities, the copper-aluminum mixture falls onto the airflow distribution plate 11 and slides downward under the action of gravity. At the same time, it is subjected to the action of high-pressure airflow. Since the density of copper is greater than that of aluminum, the copper particles overcome the airflow resistance and slide down quickly along the airflow distribution plate 11. After being guided by the second baffle plate 16, they fall into the bottom of the material collection box 15. Meanwhile, the aluminum particles are lifted upward under the action of airflow and then slowly fall into the upper discharge trough under the action of gravity. They are collected by the external collection box, thereby achieving the separation of copper and aluminum.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
