Description

Technical Field

[0001] The present application relates to the technical field of alloy processing, and in particular to a device for crushing waste cemented carbide. Background Art

[0002] Metal elements such as cobalt, tungsten, and tantalum in cemented carbide are scarce resources. With the rapid development of industrial production, the demand for cemented carbide continues to increase, and the problem of resource shortage is becoming increasingly prominent. Recycling can reduce the emission of harmful substances, reduce environmental pollution, and protect the ecological environment. In addition, the recycled cemented carbide can be reprocessed and used in production again, reducing production costs and bringing economic benefits to the enterprise. At this stage, alloy recycling generally requires crushing first.

[0003] Patent No. CN 219377238 U discloses a scrap carbide crushing device. The crushing unit is arranged between a high-temperature kettle and a water-cooling box. The crushing unit is arranged at the bottom of the high-temperature kettle. When the scrap carbide is heated to 900°C in the high-temperature kettle and continuously heated for one hour, it falls from the high-temperature kettle into a carrying net. The carrying net supports the scrap carbide. The high-temperature kettle and the crushing unit are driven downward by an electric lifting rod, so that the crushing unit is placed in the water-cooling box. Water contacts the scrap carbide through the carrying net, causing the scrap carbide to dry and crack. After drying and cracking, the high-temperature kettle and the crushing unit are driven upward by the electric lifting rod, so that the carrying net is separated from the water surface. Two sets of hydraulic cylinders drive two sets of crushing steel plates to move relatively quickly through two sets of piston rods, crushing the roller ring and rod between them. The fixed plate encloses the crushed powder and fragments, crushing the cracked roller ring and rod, and reducing the impact of the high hardness of the spoke ring and rod on the crushing steel plate.

[0004] However, in use, there are the following defects:

[0005] Although the left and right crushing steel plates are used to extrude and crush the alloy, during the extrusion process, the alloy may pop out everywhere and fly to the back side of the crushing steel plates, making it difficult to reset the crushing steel plates. In addition, during the extrusion process, part of the alloy may get stuck in the gaps of the supporting net or pass through the gaps and fall to the lower layer, making subsequent collection inconvenient and affecting the practicality of the device. Utility Model Content

[0006] The purpose of this application is to provide a device for crushing waste cemented carbide, which solves the problem raised in the background technology that during the extrusion process, the alloy may pop out everywhere and fly to the back side of the crushed steel plate, making it difficult to reset the crushed steel plate. In addition, during the extrusion process, part of the alloy may get stuck in the gap of the supporting net, or pass through the gap and fall to the lower layer, making it inconvenient for subsequent collection.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a scrap carbide crushing device, comprising a cooling pool, a support plate, a central axis and a blocking wire mesh, wherein both sides of the top of the support plate are fixedly connected with vertical plates, the top of the surface of the vertical plate away from the center of the support plate is fixedly connected with a fixed block, the bottom of the fixed block is fixedly connected with a No. 2 electric push rod, the bottom telescopic end of the No. 2 electric push rod penetrates the surface of the support plate and is fixedly connected to the top edge of the bottom plate below the support plate, the top of the bottom plate is evenly fixedly connected with a number of protrusions, and the surface of the support plate just above the protrusions is evenly penetrated.

[0008] In this technical solution, the No. 2 electric push rod shortens after startup, driving the bottom plate to rise, and the protrusion will gradually be inserted into the water screen hole until the bottom plate fits with the support plate. At this time, the surface of the support plate will become a flat surface, avoiding the alloy from getting stuck in the water screen hole or passing through the water screen hole during crushing, facilitating subsequent collection, and improving the practicality of the device; in the process of moving the crushed steel plate, the blocking steel wire mesh above the receiving roller will be pulled to move and expand together, and the broken alloy fragments will absorb kinetic energy after hitting the blocking steel wire mesh, and return to the surface of the support plate along the guide plate, and after the crushed steel plate is reset, the clockwork spring will drive the receiving roller to rotate and rewind the blocking steel wire mesh, thereby avoiding the problem of alloy fragments jumping to the back side of the crushed steel plate and affecting its reset, facilitating subsequent collection, and improving the practicality of the device.

[0009] Preferably, the bottom of the crushing steel plate is in contact with the top surface of the support plate, and the front and rear ends of the crushing steel plate are respectively in contact with the front and rear inner walls of the cooling pool.

[0015] 1. This application can temporarily close the water sieve hole through the No. 2 electric push rod, the bottom plate and the protrusion. After the No. 2 electric push rod is started, it shortens, driving the bottom plate to rise, and the protrusion will gradually be inserted into the water sieve hole until the bottom plate and the support plate are fitted together. At this time, the surface of the support plate will become a flat surface, which prevents the alloy from getting stuck in the water sieve hole or passing through the water sieve hole during the crushing process, facilitates subsequent collection, and improves the practicality of the device.

[0016] 2. The present application can block the alloy fragments through the storage roller, the clockwork spring and the blocking wire mesh. During the movement of the crushed steel plate, the blocking wire mesh above the storage roller will be pulled to move and expand together. The broken alloy fragments will absorb the kinetic energy after hitting the blocking wire mesh and return to the surface of the support plate along the guide plate.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0023] A device for crushing scrap hard alloy, see Figures 1 to 3 The top of the support plate 3 is fixed with a plurality of protrusions 5, and the top of the support plate 4 is fixed with a plurality of protrusions 5. The protrusions 5 are fixed with a plurality of protrusions 5 on the top of the support plate 3. The protrusions 5 are fixed with a plurality of protrusions 5 on the bottom of the support plate 3.

[0024] The outer surfaces of the vertical plates 8 on the left and right sides of the support plate 3 are fixedly connected to hydraulic cylinders 9, and the telescopic ends of the hydraulic cylinders 9 pass through the vertical plates 8 and are fixedly connected to the crushing steel plates 10. The top of the crushing steel plates 10 is fixedly connected to the guide plates 1001, and the top ends of the front and rear side walls of the vertical plates 8 are fixedly connected to the support blocks 11. The two ends of the central axis 122 are respectively rotatably connected to the surfaces of the support blocks 11 on both sides, and a number of spring springs 121 are connected between the central axis 122 and the outer receiving rollers 12. One end of the blocking wire mesh 13 is fixedly connected to the outer surface of the receiving roller 12, and the other end of the blocking wire mesh 13 is fixedly connected to the top of the guide plate 1001. During the movement of the crushing steel plate 10, the blocking wire mesh 13 above the receiving roller 12 will be pulled to move and unfold together, and after the crushing steel plate is reset, the spring spring 121 will drive the receiving roller 12 to rotate and rewind the blocking wire mesh 13, thereby blocking the alloy fragments and facilitating subsequent collection.

[0025] Specifically, such as Figure 2 As shown, the bottom of the crushing steel plate 10 is in contact with the top surface of the support plate 3, and the front and rear ends of the crushing steel plate 10 are respectively in contact with the front and rear inner walls of the cooling pool 2, so that the crushing steel plate 10 can crush the alloy at various positions on the support plate 3, and move back and forth under the drive of the hydraulic cylinder 9, so that the crushing is more complete.

[0026] It is worth describing that Figure 1 and Figure 2As shown, two No. 1 electric push rods 201 are fixedly connected to the front and rear sides of the top of the cooling pool 2, the top of the No. 1 electric push rod 201 is fixedly connected to the high-temperature kettle 1, and the top of the vertical plate 8 is fixedly connected to the bottom of the high-temperature kettle 1. The vertical plate 8 rises and falls with the reactor, thereby driving the support plate 3 and the bottom plate 4 to move up and down together.

[0027] It is worth noting that if Figure 2 As shown, the diameter of the protrusion 5 is consistent with the inner diameter of the water screening hole 301, and the height of the protrusion 5 is consistent with the height of the support plate 3. Therefore, when the base plate 4 and the support plate are fitted together, the top of the protrusion 5 and the top of the support plate 3 are located in the same plane, making the surface of the support plate 3 a complete plane, and metal fragments cannot enter the water screening hole 301.

[0028] It is worth noting that if Figure 2 As shown, the support plate 3 and the bottom plate 4 are of the same size and parallel to each other, and the front and rear sides of the support plate 3 and the bottom plate 4 are respectively fitted with the front and rear inner walls of the cooling pool 2, so that metal fragments will not fall into the cooling pool 2 through the gaps on the front and rear sides of the support plate 3, facilitating subsequent crushing and collection.

[0029] It is worth noting that if Figure 2 As shown, the width of the blocking steel mesh 13 is consistent with the distance between the front and rear ends of the guide plate 1001, so that sufficient blocking can be achieved, and the blocking steel mesh 13 is high in strength and can withstand the impact of alloy fragments.

[0030] After the cooling is completed, the No. 1 electric push rod 201 rises normally. At this time, in order to prevent the alloy from getting stuck in the water sieve hole 301 of the support plate 3 during the crushing process, the No. 2 electric push rod 6, the bottom plate 4 and the protrusion 5 can temporarily close the water sieve hole 301. After the No. 2 electric push rod 6 is started and shortened, the bottom plate 4 is driven to rise, and the protrusion 5 is gradually inserted into the water sieve hole 301 until the bottom plate 4 and the support plate 3 are in contact. At this time, the surface of the support plate 3 becomes a flat surface, which prevents the alloy from getting stuck in the water sieve hole 301 or passing through the water sieve hole 301 during the crushing process, thereby facilitating subsequent collection and improving the quality of the product. High practicality of the device; after closing the water screening hole 301, the hydraulic cylinder 9 is started, driving the crushing steel plate 10 to move toward the center of the support plate 3, and starting to crush the alloy. The alloy fragments can be blocked by the storage roller 12, the spring spring 121 and the blocking wire mesh 13. In the process of moving the crushing steel plate 10, the blocking wire mesh 13 above the storage roller 12 will be pulled to move and expand together. The broken alloy fragments will absorb kinetic energy after hitting the blocking wire mesh 13, and return to the surface of the support plate 3 along the guide plate 1001, and after the crushing steel plate 10 is reset, the spring spring 121 will drive the storage roller 12 to rotate and rewind the blocking wire mesh 13, thereby avoiding the problem of alloy fragments jumping to the back side of the crushing steel plate 10 and affecting its reset, facilitating subsequent collection, and improving the practicality of the device.
