[0041] The cooling spray head 105 further comprises an atomizing spray head 118 arranged below the distribution plate 114.

[0042] In addition, the cooling spray head 105 further comprises an atomizing spray head 118 arranged below the distribution plate 114 and located in or near the cooling action area of the spray head body 116. The atomizing spray head 118 atomizes part of the cooling water into fine mist, and combines with the conventional spraying mode to form a composite cooling mode, so as to cool the metal liquid not subjected to the action of the spray head body 116, to improve the cooling effect.

[0043] The material guide plate 106 comprises a second water inlet pipe 119, an overflow tank 120, a material guide cone ring body 121 and a liquid outlet plate 122.

[0044] The overflow tank 120 is arranged below the distribution plate 114 and between the cooling spray head 105 and the material guide cone ring. Its main function is to receive the excess cooling water sprayed out by the cooling spray head 105 and uniformly distribute the water flow to the surface of the material guide cone ring through the overflow structure at the edge thereof. One end of the second water inlet pipe 119 is in communication with the water tank 112, and the other end is connected to the overflow tank 120, for providing a continuous water source for the overflow tank 120 and ensuring the stable operation of the cooling system.

The other end of the push rod 125 is rotatably connected to a sliding block 126, which slides against the L-shaped plate to form a linkage mechanism. When the pusher 124 is activated, the push rod 125 drives the sliding block 126 to slide along the L-shaped plate, thereby driving the L-shaped plate to rotate around its axis. Specifically, in the closed state, the L-shaped plate is placed tilted downwards in the collection bin 107, allowing the metal balls to continue cooling in the liquid stored in the collection bin 107 for better and more stable molding.

[0050] The discharge channel 110 comprises a discharge channel body 130, a support hole plate 131, a fan 132 and an air distribution channel 133, the support hole plate 131 is arranged on one side of the L-shaped plate body 129, the discharge channel body 130 is arranged above the support hole plate 131, the air distribution channel 133 is arranged on one side of the discharge channel body 130, and the fan 132 is in communication with the air distribution channel 133.

[0051] The support hole plate 131 is arranged on one side of the L-shaped plate body 129 and serves as a basic support structure of the discharge channel body 130. The support hole plate 131 is made of a metal material with certain strength and corrosion resistance, and a plurality of through holes or grid structures are uniformly distributed on the surface of the support hole plate 131, which can allow part of the cooling gas to pass through while supporting the metal balls and allowing the residual liquid on the metal balls to flow out.

[0053] Second embodiment

[0054] The application also provides a hydrogenation waste catalyst recovery process using the hydrogenation waste catalyst recovery device.

[0055] The metal components of the waste catalyst are melted and guided to fall by the shunt hole and the flow guide ring 113 arranged below, realizing preliminary separation of the metal particles.

[0056] The metal particles in the molten state fall into the action area of the cooling nozzle 105, the cooling nozzle 105 introduces cooling water from the water tank 112 through the first water inlet pipe 117, distributes the cooling water to a plurality of inclined water outlet pipes 115 through the shunt plate 114, and sprays the cooling water to the surface of the metal particles in the form of high-pressure water flow through the nozzle body 116, so that the metal particles are quickly cooled. At the same time, the atomizing nozzle 118 releases fine water mist, further enhances the cooling effect, reduces the generation of steam, and improves the safety of the working environment.

[0057] The cooled metal particles slide along the guide cone ring body 121 with the water flow and enter the area of the guide plate 106. In this process, the second water inlet pipe 119 supplies water to the overflow groove 120 to form a water film covering the guide cone ring, which performs secondary cooling on the metal particles. Subsequently, the metal particles enter the collection barrel 107 through the liquid outlet plate 122, and the cooling water is returned to the water tank 112 through the drainage channel to realize the recycling of water resources.

[0058] After the metal particles fall into the collection barrel 107, the L-shaped control plate 109 controls the discharging rhythm according to the set program. The pusher 124 drives the push rod 125 to move the sliding block 126, thereby rotating the L-shaped plate, adjusting the opening degree of the discharge port, and realizing the quantitative discharge of the metal material. The cooperation design of the extension plate 127 and the elastic member 128 can adapt to materials with different bulk densities, ensuring stable and reliable discharging.

[0059] During the falling process of the metal particles from the discharge channel body 130, the fan 132 continuously supplies air to the air distribution channel 133, and the cooling air is distributed around the discharge channel 110 through the support hole plate 131 and the air distribution channel 133 to perform the last air cooling treatment on the metal particles, ensuring complete cooling and shaping. Finally, the metal particles fall into the storage box 111 along the discharge channel 110, completing the entire recycling process.

[0060] After the cooling water is discharged from the collection barrel 107 through the water outlet pipe 108, it returns to the water tank 112, and after filtration and purification treatment, it is used again for cooling the spray head 105 and the guide system to realize closed-loop circulation; the fan 132 is linked with the control system to automatically adjust the air volume according to the actual working condition, thereby reducing energy consumption. In addition, each component can be periodically disassembled and cleaned to ensure long-term stable operation of the device.

[0061] The above only discloses one preferred embodiment of the present application, and of course cannot limit the scope of the present application. Those skilled in the art can understand that the above-mentioned embodiment can be implemented in whole or in part, and equivalent changes made according to the claims of the present application still fall within the scope of the present application.
