Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal electrolysis equipment technology, specifically to a residual electrode crusher. Background Technology

[0002] Electrolytic refining is a common technique in non-ferrous metal smelting, especially copper smelting. It involves using an anode plate produced by pyrometallurgy as the anode, along with a cathode, to dissolve the anode and deposit metal on the cathode plate under the action of direct current and electrolyte. Because electrolytic refining technology has good controllability and a high degree of automation, it is suitable for large-scale production operations of non-ferrous metals.

[0003] In the electrolytic refining process, residual electrodes are indispensable. These residual electrodes need to be returned to the metallurgical furnace for melting. However, due to the large size of the residual electrode plates entering the furnace, optimal melting cannot be achieved, which to some extent restricts the efficiency of the return process. Patent CN219519979U discloses a residual electrode plate crushing system, including a horizontal chain conveyor, a plate separating mechanism, an inclined lifting chain conveyor, an ear-shaped cutting device, a crusher, and a discharge conveyor belt. The residual electrode crushing system reduces the particle size of the residual electrodes entering the furnace, avoiding difficulties in transporting and feeding whole anode plates into the furnace, improving the residual electrode transport and feeding capacity, and further enhancing the residual electrode processing capacity of the metallurgical furnace. At the same time, the connection between the various chain conveyors and the plate separating and cutting devices facilitates the integrated synchronous operation of residual electrode plate conveying, cutting, and crushing, effectively increasing the residual electrode plate conveying speed and the return processing capacity.

[0004] A crucial piece of equipment in an electrolytic electrode crushing system is the electrode crusher, which can be either a jaw crusher or a roller crusher. For example, patent CN206315846U discloses an electrode crusher using a jaw crusher, while patent CN219519979U discloses an electrode plate crushing system using a roller crusher. However, electrolytic electrodes are high-purity metal plates, especially copper, nickel, and lead, which are relatively soft and have a certain degree of toughness. Existing jaw crushers and roller crushers rely on impact compression to crush the material, but for copper, nickel, and lead electrodes, which are relatively tough, the crushing effect is poor, failing to achieve the desired crushing effect, and the failure rate is relatively high. Utility Model Content

[0005] The purpose of this utility model is to provide a residual electrode crusher to solve the technical problem of poor and unsatisfactory residual electrode crushing effect of non-ferrous metals such as copper, nickel and lead.

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

[0007] A residual crusher includes a frame 1, a drive roller 3 and a driven roller 4 disposed in the inner cavity of the frame 1, and a pulley 10 disposed on the shaft of the drive roller 3. Two inclined guide grooves 8 are symmetrically arranged on the left and right side walls of the frame 1, and the shafts of the drive roller 3 and the driven roller 4 are respectively placed in the two inclined guide grooves 8. Teeth 31 are provided on the drive roller 3 and the driven roller 4. The pulley 10 is disposed on the shaft of the drive roller 3 on the outer side of the frame 1.

[0008] Furthermore, vertical guide grooves 9 are provided on the left and right side walls of the frame 1. The vertical guide grooves 9 are located on the symmetrical center line of the two inclined guide grooves 8 and are located above the inclined guide grooves 8. A drive gear 5 is provided on the shaft of the drive roller 3. The drive gear 5 is located between the frame 1 and the pulley 10. A driven gear 6 is provided on the shaft of the driven roller 4. The driven gear 6 is located outside the frame 1. The shaft of the transmission gear 7 is provided in the vertical guide grooves 9. The transmission gear 7 meshes with the drive gear 5 and the driven gear 6 respectively.

[0009] Furthermore, the bottom end of the vertical guide groove 9 is located 10-30mm from the line connecting the top ends of the two inclined guide grooves 8, and the length of the vertical guide groove 9 is 120-300mm.

[0010] Furthermore, the angle between the inclined guide groove 8 and the vertical line is 20° to 35°, and the length of the inclined guide groove 8 is 200 to 380 mm.

[0011] Furthermore, an inner lining plate 2 is provided on the inner wall of the frame 1.

[0012] Furthermore, a guide plate 12 is provided inside the upper opening of the frame 1.

[0013] Furthermore, it also includes a motor 11, which is used to drive the pulley 10.

[0014] Furthermore, the spacing between the teeth 31 is greater than the width of the bottom surface of the teeth 31.

[0015] Furthermore, the upper end face of the tooth 31 is smaller than the lower end face.

[0016] Furthermore, the upper surface of the tooth 31 is blade-shaped.

[0017] Compared with existing technologies, this utility model of a residual electrode crusher employs two symmetrically arranged inclined guide grooves on the left and right side walls of the frame for mounting drive rollers and driven rollers. Teeth are provided on both the drive rollers and driven rollers. When residual electrodes enter between the drive rollers and driven rollers, the teeth on the drive rollers and driven rollers engage under the winding force of the drive rollers. Due to the effect of the inclined guide grooves, the distance between the drive rollers and driven rollers gradually decreases, slowly shearing the residual electrodes. When no residual electrodes enter, the drive rollers move away from the driven rollers under the drive of the motor. This utility model uses a double-roller mechanism to drive the teeth on the rollers to shear the residual electrodes, overcoming the toughness of the residual electrodes, resulting in good crushing effect and low noise.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1-4As shown, this utility model provides a residual crusher, including a frame 1. A drive roller 3 and a driven roller 4 are arranged parallel to each other in the inner cavity of the frame 1. Two inclined guide grooves 8 are symmetrically arranged on the left and right side walls of the frame 1, with the angle between the inclined guide grooves 8 and the vertical line being 20° to 35° and the length of the inclined guide grooves 8 being 200 to 380 mm. The shafts of the drive roller 3 and the driven roller 4 are respectively placed in the two inclined guide grooves 8. A pulley 10 is arranged on the shaft of the drive roller 3 on the outer side of the frame 1. Teeth 31 are provided on the drive roller 3 and the driven roller 4. A motor 11 drives the pulley 10 to rotate, driving the drive roller 3. A feed inlet is also provided on the upper casing of the frame 1, and a discharge inlet is also provided on the lower casing of the frame 1. The residual electrode enters the residual electrode crusher through the feed inlet. The motor 11 drives the pulley 10 to rotate, and the shaft of the pulley 10 drives the drive roller 3 to rotate. When the residual electrode enters between the drive roller 3 and the driven roller 4, under the action of the winding force of the drive roller 3, the drive roller 3, the driven roller 4 and the residual electrode all move downward. The teeth 31 on the drive roller 3 and the driven roller 4 apply shear force to the residual electrode. As the shear force increases, the residual electrode is sheared into residual electrode fragments of a certain size, achieving the expected purpose. Moreover, the crushing effect is good and the noise is low.

[0025] like Figure 1-4 As shown, in one embodiment of this invention, vertical guide grooves 9 are added to the left and right side walls of the frame 1. These vertical guide grooves 9 are located on the symmetrical center line of the two inclined guide grooves 8 and are positioned above them. A drive gear 5 is mounted on the shaft of the drive roller 3, located between the frame 1 and the pulley 10. A driven gear 6 is mounted on the shaft of the driven roller 4, located outside the frame 1. A transmission gear 7 is mounted within the vertical guide grooves 9, meshing with both the drive gear 5 and the driven gear 6. Thus, the pulley 10 drives the drive roller 3 to rotate, the drive gear 5 rotates with the drive roller 3, the drive gear 5 drives the transmission gear 7 to rotate, the transmission gear 7 drives the driven gear 6 to rotate, and the driven roller 4 rotates with the driven gear 6. Under the action of the transmission gear 7, the drive roller 3 and the driven roller 4 simultaneously act on the residual electrode to provide a shearing effect on the residual electrode. Furthermore, the transmission gear 7 is set in the vertical guide groove 9 and can move with the movement of the drive roller 3 and the driven roller 4. Considering the residual thickness of this utility model and the vertical movement distance of the drive gear 5 and the driven gear 6, the bottom end of the vertical guide groove 9 is best located 10 to 30 mm from the line connecting the top ends of the two inclined guide grooves 8, and the length of the vertical guide groove 9 is 120 to 300 mm.

[0026] like Figure 1-2 As shown, in order to provide the shearing effect of the drive roller 3 and the driven roller, and to give the drive roller 3 and the driven roller a larger moving space, and to be suitable for crushing residues of different thicknesses, the angle between the inclined guide groove 8 and the vertical line is set to 20° to 35°, and the length of the inclined guide groove 8 is 200 to 380 mm.

[0027] like Figure 3As shown, during the crushing process, crushed particles may enter between the drive roller 3 and the side wall of the frame 1, as well as between the driven roller 4 and the side wall of the frame 1. To prevent wear on the side walls, an inner liner 2 is installed on the inner wall of the frame 1. In addition, the residual electrode generally has a certain impact force when entering the crusher. If it falls directly onto the drive roller 3 or the driven roller 4, it will damage the rollers and teeth 31. In order to prevent the residual electrode from entering between the drive roller 3 and the side wall of the frame 1, as well as between the driven roller 4 and the side wall of the frame 1, a guide plate 12 is installed inside the upper opening of the frame 1.

[0028] like Figure 4 As shown, in the residual electrode crusher of this utility model, the residual electrode is crushed by the shearing action of the teeth 31. In order to ensure the shearing effect, the teeth 31 should be able to contact the roller surface. Therefore, the spacing of the teeth 31 is greater than the width of the bottom surface of the teeth 31, and the upper end surface of the teeth 31 is smaller than the lower end surface. The most advantageous structure of the teeth 31 is that the upper end surface of the teeth 31 is blade-shaped, similar to a knife edge.

[0029] As described above, this utility model's residual electrode crusher employs two symmetrically arranged inclined guide grooves on the left and right side walls of the frame for mounting the drive roller and driven roller. Teeth are also provided on both the drive roller and the driven roller. When residual electrodes enter between the drive roller and the driven roller, the teeth on the drive roller and the driven roller engage under the winding force of the drive roller. Due to the effect of the inclined guide grooves, the distance between the drive roller and the driven roller gradually decreases, slowly shearing the residual electrodes. When no residual electrodes enter, the drive roller moves away from the driven roller under the drive of the motor. This utility model uses toothed engagement to shear the residual electrodes, overcoming their toughness, resulting in good crushing effect and low noise.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
