Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] According to an embodiment of the utility model, a magnetic suction feeding device for a smelting furnace is provided.

[0021] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-3As shown, according to the embodiment of the utility model, the magnetic suction feeding device for the smelting furnace includes an inclined barrel 1, a bottom plate 7 and a bottom box 8. The bottom of the inclined barrel 1 is welded with the bottom box 8, and the left side of the bottom box 8 is welded with the bottom plate 7. The bottom box 8 and the bottom plate 7 are welded to the inclined barrel 1 through oblique braces in opposite directions. A winch 3 is fixedly installed on the top surface of the upper part of the inclined barrel 1 by bolts, and a steel wire rope 4 is wound and connected on the drum of the winch 3. A blanking nozzle 2 is arranged on the bottom surface of the upper part of the inclined barrel 1, and a feeding oblique bucket 10 is obliquely arranged on the side of the lower part of the inclined barrel 1, and A transfer box 6 is welded to one end of the feeding inclined bucket 10, and a material suction port is provided on the bottom surface of the lower part of the inclined barrel 1 corresponding to the transfer box 6. One end of the steel wire rope 4 passes through the inclined barrel 1 and extends into the bottom box 8. A counterweight block 9 is provided on the inside of the bottom box 8, and the side of the counterweight block 9 is connected to the steel wire rope 4 through a connecting ear. An electromagnet 5 is provided inside the inclined barrel 1, and a clamp 11 is welded to the top of the electromagnet 5. The clamp 11 is clamped with the steel wire rope 4 passing through the inclined barrel 1. A guide groove 12 is provided on the inner wall of the inclined barrel 1, and the shell side of the electromagnet 5 A guide block 17 is fixedly connected, and the guide block 17 is slidably connected to the guide groove 12. In order to facilitate the electromagnet 5 to adsorb scrap metal materials, the distance between the transfer box 6 and the electromagnet 5 does not exceed the optimal adsorption range of the electromagnet 5. In order to facilitate feeding, the height of the blanking nozzle 2 matches the feeding port of the smelting furnace. The winch 3 and the electromagnet 5 are only used in this patent, and their structure and function are not improved. For technicians in this field, their setting method, installation method and electrical connection method, as long as they are debugged and operated according to the requirements of their instruction manual, they will not be repeated here. The winch 3 and the electromagnet 5 are both provided with a control switch matched therewith. The installation position of the control switch is selected according to the actual use requirements, which is convenient for the operator to operate and control. The control method of the utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply belong to the common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model does not explain the control method and wiring arrangement in detail.

[0022] In one embodiment, a first fixed pulley 13 is provided at both ends of the inclined material barrel 1, and a second fixed pulley 14 and a third fixed pulley 15 are provided on the bottom box 8 and the bottom plate 7 respectively. The part of the wire rope 4 passing through the inclined material barrel 1 is entangled and connected with the first fixed pulley 13, the second fixed pulley 14 and the third fixed pulley 15 respectively. Since the counterweight block 9 in the bottom box 8 is connected to the wire rope 4, the wire rope 4 can be kept taut during the winding and unwinding process of the wire rope 4, providing stable support for the reciprocating movement of the electromagnet 5. The setting of the first fixed pulley 13, the second fixed pulley 14 and the third fixed pulley 15 can, on the one hand, be rollingly connected with the wire rope 4, and on the other hand, enable the walking path of the counterweight block 9 to be adapted to the feeding path of the electromagnet 5.

[0023] In one embodiment, a transition inclined plate 16 is welded to the inner side of the connection between the transfer box 6 and the loading inclined bucket 10, and the side of the transfer box 6 is welded to the outer wall of the inclined barrel 1 through a metal support. Through the setting of the transition inclined plate 16, the scrap metal material can slide to the left side of the transfer box 6 as much as possible, avoiding the accumulation of scrap metal material between the transfer box 6 and the loading inclined bucket 10, thereby ensuring the adsorption effect of the electromagnet 5.

[0024] In one embodiment, the transfer box 6 and the inclined material barrel 1 are arranged in parallel, the loading inclined bucket 10 is arranged obliquely with respect to the inclined material barrel 1, and the transfer box 6 is located below the electromagnet 5. Through the setting of the transfer box 6, the scrap metal material introduced by the loading inclined bucket 10 can be continuously introduced into the transfer box 6 under the action of gravity, so as to facilitate the magnetic feeding of the electromagnet 5.

[0025] In one embodiment, an opening is provided on the left side of the bottom box 8, and through holes are provided on the surfaces of the bottom box 8 and the inclined barrel 1 corresponding to the steel wire rope 4. The opening is provided to make room for the steel wire rope 4 and the counterweight 9, and the through hole is provided to make room for the threading of the steel wire rope 4.

[0026] In one embodiment, the clamp 11 is composed of a metal strip and an arc-shaped bent portion at the top thereof that is connected to and wrapped around the steel wire rope 4. By setting the clamp 11, the reliability of the connection between the steel wire rope 4 and the electromagnet 5 can be maintained, and the movement of the electromagnet 5 is facilitated.

[0027] Working principle:

[0028] When in use, first pour the scrap metal material into the loading inclined bucket 10, and the scrap metal material slides into the transfer box 6 under the action of the loading inclined bucket 10 and the inner transition inclined plate 16, so that the scrap metal material is in the adsorption range of the electromagnet 5. When the smelting furnace is fed, the wire rope 4 is wound by starting the winch 3, so that the wire rope 4 pulls the electromagnet 5 fixed on its surface with a clamp 11 to be lifted, and then the guide blocks 17 on both sides of the shell of the electromagnet 5 slide along the guide grooves 12 opened on the inner wall of the inclined barrel 1, so that the electromagnet 5 is transferred from the transfer box 6 to the blanking nozzle 2. In this process, the electromagnet 5 at the transfer box 6 is started. 5, the scrap metal materials that the loading inclined bucket 10 slides into the transfer box 6 are adsorbed by the electromagnet 5. When the transfer box 6 is at the blanking nozzle 2, the electromagnet 5 is closed, and the scrap metal materials adsorbed on the surface of the electromagnet 5 enter the feeding port of the smelting furnace through the blanking nozzle 2, and then the winch 3 is started to rotate forward and reverse, so that the steel wire rope 4 forces the electromagnet 5 to reciprocate between the transfer box 6 and the blanking nozzle 2 during the winding and unwinding process, thereby realizing continuous feeding of the scrap metal materials. During this process, the counterweight block 9 in the bottom box 8 is connected to the steel wire rope 4, and the steel wire rope 4 can be kept taut during the winding and unwinding process, providing stable support for the reciprocating movement of the electromagnet 5.
