Description

Technical Field

[0001] This utility model relates to the field of magnetic separation and iron removal technology, specifically to a magnetic separation device for impurities in copper rod processing. Background Technology

[0002] During the processing of copper rods, copper powder is generated from processes such as cutting and grinding. Since copper powder often contains ferromagnetic impurities, which affect the quality and performance of copper products, magnetic separation technology is often used to remove iron. This technology utilizes magnetic differences to separate impurities and ensure the purity of the copper powder.

[0003] Utility model patent CN110893378B discloses a magnetic separator, which includes a base and a support frame. A material box is slidably connected to the support frame, and a return spring is provided between the base and the material box. A switch for controlling the material box's discharge is provided at the discharge end of the material box. A support seat is provided on the base below the material box's discharge end, and an electromagnetic roller is rotatably connected to the support seat. An iron scrap box and a copper material box are provided on the base below the electromagnetic roller. A knife switch is provided on the base to control the opening and closing of the switch and the on / off state of the electromagnetic roller. A drive unit is provided on the material box to drive the knife switch to open and close. This invention has the following advantages and effects: by using an electromagnetic roller instead of a traditional permanent magnet roller, the descrambling process of magnetic materials is more thorough; furthermore, by using a fully automated magnetic separator to screen copper powder and setting up an electromagnetic roller with automatic power-off descrambling, the magnetic separation rate of copper powder is significantly improved, thereby achieving the effect of improving magnetic separation efficiency.

[0004] The magnetic separator described in the prior art only uses a single adsorption of the electromagnetic roller to magnetically separate copper powder. The copper powder slides from the feed box through the guide chute onto the outer wall of the electromagnetic roller and is directly thrown off and collected under centrifugal force. The magnetic separation path is short, and the contact time between impurities and copper powder with the electromagnetic roller is limited. This results in some fine magnetic impurities being difficult to be fully adsorbed and separated, leading to incomplete magnetic separation and affecting the purity of the copper powder. In view of this, we propose an impurity magnetic separation device for copper rod processing. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic separation device for impurities in copper rod processing, so as to solve the problems mentioned in the background art.

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

[0007] A magnetic separation device for impurities in copper rod processing includes a base with an inclined top surface that is lower in the front and higher in the back. A material box is provided at the rear end of the base, and a discharge hopper is provided at the front end of the base. A discharge mechanism is connected below the material box. A rotary magnetic separation mechanism capable of axial rotation is provided between the material box and the discharge hopper. Copper powder in the discharge hopper is initially magnetically separated by the discharge mechanism and then transported to the rotary magnetic separation mechanism for further magnetic separation.

[0008] The discharge mechanism includes a discharge pipe, inside which is an axially rotatable auger. A rectangular vertical pipe is provided at the top of the discharge pipe, and the top of the vertical pipe is connected to the bottom of the material box. A side window is provided on the right side wall of the vertical pipe. A sloping baffle is fixed on the left inner wall of the vertical pipe corresponding to the position of the side window. The sloping baffle gradually slopes downward from left to right. A preliminary magnetic separation component is embedded in the side window. The preliminary magnetic separation component includes a side plate and several magnetic separation plates fixed on the left end face of the side plate. A magnetic sheet is embedded on the top surface of the magnetic separation plate. The magnetic separation plate gradually slopes downward from right to left.

[0009] The rotary magnetic separator includes a rotating drum and a spiral plate fixed on the inner wall of the rotating drum, and several electromagnets are installed on the outer wall of the rotating drum.

[0010] Preferably, the bottom of the material box is provided with a plurality of support legs, the bottom of which is fixedly connected to the base;

[0011] In this setup, the support legs securely fix the material box to the base, preventing it from shaking when loading copper powder.

[0012] Preferably, the front end of the discharge pipe is open and the rear end of the discharge pipe is closed. A conveying motor is installed on the rear end face of the discharge pipe, and the end of the output shaft of the conveying motor is coaxially connected to the auger.

[0013] In this setup, the conveyor motor drives the auger to rotate during operation, enabling the directional conveying of copper powder from the rear end to the front end of the discharge pipe.

[0014] Preferably, a plurality of connecting plates are fixed to the top of the discharge pipe, and the top of the connecting plates is fixedly connected to the bottom of the material box.

[0015] In this configuration, the connecting plate enhances the connection stability between the discharge pipe and the material box, preventing structural swaying during conveying.

[0016] Preferably, the inclined baffle and the magnetic separator are arranged in an alternating pattern inside the vertical tube. Gaps are left between the bottom end of the inclined baffle and the left end face of the side plate, and between the bottom end of the magnetic separator and the left inner wall of the vertical tube, to allow copper powder to pass through. The copper powder falling from the material box passes sequentially over the surfaces of the magnetic separator and the inclined baffle.

[0017] In this setup, the staggered oblique baffles and magnetic separators form an S-shaped path, extending the contact time between the copper powder and the magnetic plates and improving the initial magnetic separation effect.

[0018] Preferably, the side plate is detachably mounted to the side window by bolts, and a handle is mounted on the right end face of the side plate;

[0019] In this setup, the detachable side panel, along with the handle, makes it easy for operators to periodically clean the magnetic impurities adsorbed on the magnetic separator plate.

[0020] Preferably, two rows of four pairs of protrusions are fixed on the top surface of the base located below the rotary magnetic separator. A rotating column is rotatably connected between the top ends of each pair of protrusions. An annular groove is formed on the outer peripheral surface of the rotating column. A convex ring is formed on the outer peripheral surface of both the front and rear ends of the rotating drum. The convex ring extends into the corresponding annular groove. A rotating motor is coaxially connected to one of the rotating columns.

[0021] In this configuration, the boss and the rotating column support the rotating cylinder, and the annular groove and the convex ring cooperate to restrict the radial movement of the rotating cylinder.

[0022] Preferably, the front end of the discharge pipe extends into the rear end of the rotating drum, and the front end of the rotating drum extends above the discharge hopper;

[0023] In this setup, the discharge pipe is positioned in accordance with the rotating drum and the discharge hopper to ensure that the copper powder falls accurately into the discharge hopper after passing through the preliminary magnetic separation and the rotary magnetic separation in sequence.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This magnetic separation device for copper rod processing uses a two-stage magnetic separation structure consisting of a preliminary magnetic separation component and a rotating magnetic separation mechanism. Copper powder is first initially adsorbed by the magnetic separation plate in the discharge mechanism, and then enters the rotating magnetic separation mechanism. The copper powder is guided along the spiral path by the spiral plate on the inner wall of the rotating drum. Combined with the continuous action of the electromagnet on the outer wall of the rotating drum, the contact time between impurities and magnetic components and the magnetic separation path are extended, which can more fully separate magnetic impurities in copper powder and improve the purity of copper powder.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-8A magnetic separation device for impurities in copper rod processing includes a base 100. The top surface of the base 100 is inclined, with the front lower than the back. This inclined design facilitates the movement of copper powder towards the discharge hopper 140 under gravity. A material box 110 is located at the rear end of the base 100, and several support legs are provided at the bottom of the material box 110. The bottom ends of these support legs are fixedly connected to the base 100. A discharge hopper 140 is located at the front end of the base 100. A discharge mechanism 200 is connected below the material box 110. An axially rotatable rotary magnetic separation mechanism 300 is provided between the material box 110 and the discharge hopper 140. The copper powder in the discharge hopper 140 is initially magnetically separated by the discharge mechanism 200 and then conveyed to the rotary magnetic separation mechanism 300 for further magnetic separation.

[0040] like Figure 4 As shown, in this utility model, the discharge mechanism 200 includes a discharge pipe 210, inside which is an axially rotatable auger 211. The front end of the discharge pipe 210 is open, and the rear end is closed. A conveying motor 212 is mounted on the rear end face of the discharge pipe 210, and the output shaft of the conveying motor 212 is coaxially connected to the auger 211. By starting the conveying motor 212, the conveying motor 212 can drive the auger 211 to rotate, thereby conveying the copper powder falling from the material box 110 from the rear end to the front end of the discharge pipe 210, realizing the directional transmission of the copper powder.

[0041] like Figure 4 and Figure 5 As shown, specifically, several connecting plates 214 are fixed to the top of the discharge pipe 210, and the top of the connecting plates 214 are fixedly connected to the bottom of the material box 110. The connecting plates 214 fix the discharge pipe 210 to the material box 110, enhancing the structural stability of the discharge mechanism 200 and the material box 110, and preventing shaking during copper powder conveying.

[0042] like Figure 1 ,and Figures 4-7As shown, further, the top of the discharge pipe 210 is provided with a rectangular vertical pipe 213. The top of the vertical pipe 213 is connected to the bottom of the material box 110. The vertical pipe 213 connects the material box 110 and the discharge pipe 210, providing a falling channel for copper powder. A side window 2131 is provided on the right side wall of the vertical pipe 213. A sloping baffle 2132 is fixed on the left inner wall of the vertical pipe 213 corresponding to the position of the side window 2131. The sloping baffle 2132 gradually slopes downward from left to right. A preliminary magnetic separation component 220 is embedded in the side window 2131. The preliminary magnetic separation component 220 includes a side plate 221 and several magnetic separation plates 222 fixed on the left end face of the side plate 221. A magnetic piece 2221 is embedded on the top surface of the magnetic separation plate 222. The magnetic separation plate 222 gradually slopes downward from right to left. The inclined baffle 2132 and the magnetic separator 222 are arranged in an alternating pattern inside the vertical tube 213. Copper powder falling from the material box 110 passes sequentially over the surfaces of the magnetic separator 222 and the inclined baffle 2132. The alternating arrangement of the inclined baffle 2132 and the magnetic separator 222 forms an S-shaped path. The copper powder first passes over the surface of the magnetic separator 222, where the magnetic impurities it carries are attracted by the magnetic sheet 2221. Then, it is guided by the inclined baffle 2132 to continue falling, extending the initial magnetic separation time and improving the impurity separation efficiency. Gaps are provided between the bottom end of the inclined baffle 2132 and the left end face of the side plate 221, and between the bottom end of the magnetic separator 222 and the left inner wall of the vertical tube 213, to allow copper powder to pass through. The gap design ensures that the copper powder passes through smoothly and avoids clogging.

[0043] like Figure 6 and Figure 7 As shown, the side plate 221 is detachably mounted in the side window 2131 by bolts, and a handle 2211 is mounted on the right end face of the side plate 221. The detachable design of the side plate 221 facilitates the periodic removal of the magnetic separator 222 to clean the magnetic impurities adsorbed on the magnetic sheet 2221; the handle 2211 makes it convenient for operators to hold and remove the side plate 221, improving maintenance convenience.

[0044] like Figure 1 and Figure 8 As shown, it is worth noting that the rotary magnetic separator 300 includes a rotating drum 310 and a spiral plate 320 fixed on the inner wall of the rotating drum 310. The spiral plate 320 on the inner wall of the rotating drum 310 guides the copper powder to move along the spiral path towards the front end of the rotating drum 310, extending the residence time of the copper powder in the rotating drum 310. Several electromagnets 311 are installed on the outer wall of the rotating drum 310. When the electromagnets 311 are energized, they generate magnetism and perform secondary adsorption on the residual magnetic impurities in the copper powder, achieving more thorough magnetic separation in conjunction with the spiral path. The front end of the discharge pipe 210 extends into the rear end of the rotating drum 310, and the front end of the rotating drum 310 extends above the discharge hopper 140, ensuring that the copper powder after preliminary magnetic separation accurately enters the rotary magnetic separator 300.

[0045] like Figures 1-3As shown, it should be added that two rows of four pairs of protrusions 120 are fixed on the top surface of the base 100 below the rotary magnetic separator 300. A rotating column 130 is rotatably connected between the top ends of each pair of protrusions 120. An annular groove 132 is formed on the outer circumferential surface of the rotating column 130. A protruding ring 312 is formed on the outer circumferential surface of both the front and rear ends of the rotating drum 310. The protrusions 120 and the rotating column 130 form a support structure. The annular groove 132 and the protruding ring 312 cooperate to restrict the radial movement of the rotating drum 310, ensuring the stability of the rotating drum 310 during rotation. One of the rotating columns 130 is coaxially connected to a rotating motor 131. By starting the rotating motor 131, the rotating motor 131 drives the rotating column 130 to rotate, thereby causing the rotating column 130 to drive the rotating drum 310 to rotate synchronously, providing power for the spiral plate 320 to transport copper powder.

[0046] It is worth noting that the rotating motor 131, the conveying motor 212, and the electromagnet 311 involved in this utility model are all existing conventional technologies, and will not be described in detail in this utility model.

[0047] In this embodiment, when the copper rod processing impurity magnetic separation device is in use, firstly, copper powder is loaded into the material box 110 and falls into the discharge pipe 210 through the vertical pipe 213 under the action of gravity. It is then conveyed to the area of ​​the preliminary magnetic separation component 220 by the auger 211. At this time, the copper powder falls along the intersecting path of the inclined baffle 2132 and the magnetic separation plate 222. The magnetic impurities are attracted by the magnetic pieces 2221 of the magnetic separation plate 222, thus completing the preliminary magnetic separation.

[0048] Then, the copper powder after preliminary magnetic separation enters the rotating drum 310 of the rotary magnetic separator 300 through the front end of the discharge pipe 210. By starting the rotating motor 131, the rotating column 130 drives the rotating drum 310 to rotate. At this time, under the guidance of the spiral plate 320, the copper powder moves along the spiral path to the front end of the rotating drum 310. At the same time, the electromagnet 311 is energized to generate magnetism, which adsorbs the copper powder a second time and further separates the residual magnetic impurities.

[0049] Finally, the pure copper powder falls from the front end of the rotary drum 310 into the discharge hopper 140 for collection. After the copper powder is magnetically separated, the magnetic impurities adsorbed on the magnetic separation plate 222 can be cleaned by disassembling the side plate 221, while the magnetically separated impurities adsorbed by the electromagnet 311 can be automatically collected after the electromagnet 311 is de-energized.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
