Description

Technical Field

[0001] This utility model relates to the field of zinc ingot pretreatment technology, and in particular to a hydraulic pretreatment device for zinc ingots. Background Technology

[0002] Hard alloys typically consist of hard phases such as tungsten carbide and binder phases such as cobalt and nickel. During hard alloy recycling, zinc can form a low-melting-point alloy with the binder metals (such as cobalt and nickel). At a certain temperature, zinc and the binder metals form a zinc-cobalt solid solution alloy, thereby separating the binder metal from the hard alloy, disrupting its structure, and transforming the dense alloy into a loose hard phase framework, facilitating subsequent separation and recovery of the hard and binder phases.

[0003] Zinc is used as a raw material for the recycling of cemented carbide. It is generally produced and transported in the form of zinc ingots. Before large zinc ingots react with cemented carbide by heating, they need to be processed into smaller pieces to facilitate subsequent heating and melting, and reaction with the binder metal in the cemented carbide. This utility model provides a zinc ingot pretreatment device. Utility Model Content

[0017] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0018] like Figure 1As shown, a zinc ingot hydraulic pretreatment device includes a frame 1, a hydraulic cylinder 2, a hydraulic oil tank 3, an oil pump 4, a solenoid directional valve 5, a top-loading mechanism, and a cutting frame 12. The frame 1 is a rectangular frame structure. The hydraulic cylinder 2 is installed on the lower side of the top of the frame 1. The hydraulic oil tank 3 is installed on the top of the frame 1. The oil pump 4 and the solenoid directional valve 5 are installed on the hydraulic oil tank 3. The solenoid directional valve 5 is a two-position four-way solenoid directional valve. The two working oil ports 17 of the solenoid directional valve 5 are connected to the two interfaces of the hydraulic cylinder 2 through the upper hydraulic pipe 7 and the lower hydraulic pipe 8, respectively. The oil inlet of the solenoid directional valve 5 is connected to one end of the oil delivery pipe 15. The other end of 5 is connected to the oil outlet of the oil pump 4. The oil inlet of the oil pump 4 is connected to the hydraulic oil tank 3 through the oil suction pipe 14. The oil outlet of the electromagnetic reversing valve 5 is connected to the return oil pipe 16. The return oil pipe 16 is connected to the hydraulic oil tank 3. The rise and fall of the piston rod 9 is controlled by the electromagnetic reversing valve 5. The top material mechanism is fixedly installed at the bottom end of the piston rod 9 of the hydraulic cylinder 2. The cutting frame 12 is installed on the frame 1 below the top material mechanism. Multiple cutting blades 20 are installed on the cutting frame 12. The top material mechanism includes a top plate 10 and a top block 11. Multiple top blocks 11 are fixedly installed below the top plate 10. The multiple top blocks 11 and multiple cutting blades 20 are staggered.

[0019] Furthermore, the cutting rack 12 has several blade grooves 19 on both sides, and the cutting blade 20 has a long strip structure. The two ends of the cutting blade 20 are inserted into the blade grooves 19. The cutting blade 20 can be selectively placed in the blade grooves 19 to adjust the size of the zinc material after cutting. At the same time, this structure facilitates the replacement of the cutting blade 20.

[0020] Furthermore, the bottom of the cutting rack 12 is equipped with an inclined sliding plate 13, which slides the shredded zinc material to the material collection position to avoid material accumulation.

[0021] Furthermore, a hydraulic gauge 6 is installed on the inlet end of the electromagnetic directional valve 5 to monitor whether the hydraulic oil circuit is blocked.

[0022] Furthermore, such as Figure 2 As shown, the oil inlet end of the oil suction pipe 14 is provided with a filter cover 18, and the filter cover 18 is provided with filter holes. By setting the filter cover 18, impurities in the hydraulic oil tank 3 are filtered, reducing the risk of oil circuit blockage.

[0023] Working principle: Place the cutting blade 20 into the corresponding blade slot 19, adjust the cutting size, and then place the zinc ingot to be cut onto the cutting rack 12. Start the oil pump 4 and control the solenoid reversing valve 5 to move the piston rod 9, which drives the top plate 10 and top block 11 to move downward, pressing down on the upper end of the zinc ingot. The cutting blade 20 cuts the zinc ingot. The cut zinc material slides along the sliding plate 13 to the material collection area. After the cutting is completed, the solenoid reversing valve 5 reverses, the piston rod 9 moves upward, and a new zinc ingot to be processed is manually replaced onto the cutting rack 12. Repeat the above operation to process the next zinc ingot.
