Description

Technical Field

[0001] This utility model relates to the field of ferromolybdenum alloy smelting technology, specifically to a crude ingot spray cooling device for ferromolybdenum alloy production. Background Technology

[0002] To improve the cooling efficiency of ferromolybdenum alloy ingots after casting and to reduce their hardness and the difficulty of subsequent crushing operations, Chinese patent application CN211233979U discloses a spray cooling system for ferromolybdenum ingots. The system involves a spray chamber set up on the ground, with a condenser fan and spray pipe network installed on top. A cooling water tank is installed underground, connected to the spray pipe network via a cooling water inlet pipe, and connected to the condenser fan via a condensate return pipe. The spray chamber provides an independent spray space for the spray cooling of the ferromolybdenum ingots. After spray cooling, the grain size of the microcrystalline structure of the ferromolybdenum ingot rapidly increases, altering the crystallization state of the microcrystalline structure, reducing the hardness of the ferromolybdenum alloy, making the ferromolybdenum ingot easier to crush, and improving the crushing effect of the ferromolybdenum ingot. However, in this scheme, the spraying network is only set at the top, resulting in a limited spraying coverage area, which affects the spraying cooling efficiency of ferromolybdenum alloy ingots. In addition, during the spraying operation, a large amount of cooling water flows downward under the action of gravity, which causes serious erosion to the flatbed transport vehicle, rail track and rail subgrade. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Refer to the appendix of the instruction manual Figure 1-3As can be seen, this application addresses the problems in the prior art where the spray pipe network is only installed at the top, resulting in limited spray coverage area, affecting cooling efficiency, and causing severe erosion of the flatbed transport vehicle 4, rail track 3, and rail subgrade 2 by cooling water during spraying operations. Specifically, it designs a spray cooling device for crude ingots used in ferromolybdenum alloy production, including a spray chamber 1 and a rail track 3 installed on the subgrade 2 at the bottom of the spray chamber 1. A flatbed transport vehicle 4 is mounted on the rail track 3. A first traction mechanism 5 and a second traction mechanism 6 are respectively installed on both sides of the spray chamber 1. A U-shaped spray component is installed inside the spray chamber 1, with one end of the U-shaped spray component... It is connected to the cooling water supply mechanism; a rectangular support seat 8 is installed on the flatbed transport vehicle 4 to support the steel pallet 7, and drain ports 9 are respectively installed on the lower parts of both sides of the steel pallet 7; a water collection pool 10 is constructed at the bottom of the spray room 1, and a reinforced concrete support beam 11 is installed in the middle of the water collection pool 10 to support the roadbed 2. Converging channels 12 are symmetrically arranged on both sides of the water collection pool 10, and a grid plate 13 is installed on the top of the converging channel 12. A guide channel 14 is installed on one side of the converging channel 12 along the inclined direction, and the upper end of the guide channel 14 extends into the lower part of the steel pallet 7; a sedimentation filter tank 15 and a cooling tower 16 are sequentially connected to one side of the water collection pool 10. The existing ferromolybdenum ingot spray cooling system is improved by including a cold water tank 17. During operation, the first traction mechanism 5 pulls the flatbed transport vehicle 4 to move the ferromolybdenum alloy ingot to the spray chamber 1. The cooling water supply mechanism extracts the spray water from the cold water tank 17 and supplies it to the U-shaped spray components inside the spray chamber 1, significantly increasing the contact area between the spray cooling water and the ferromolybdenum ingot, thereby effectively improving cooling efficiency. A water collection tank 10 is provided at the bottom of the spray chamber 1. The runoff cooling water enters the water collection tank 10 and then flows into the sedimentation and filtration tank 15 for sedimentation and filtration. The filtered water then enters the cooling system. Tower 16 performs heat exchange and cooling, and the cooled water is returned to the cold water pool 17 for recycling. A reinforced concrete support beam 11 is set in the middle of the water collection pool 10 to support the roadbed 2 and ensure the structural stability of the rail track 3 path. During the spray cooling operation, the cooling water that flows from the surface of the alloy ingot into the steel tray 7 is further discharged through the drain port 9 on the steel tray 7, and the water flowing out of the steel tray 7 is guided by the guide channel 14, thereby effectively preventing the cooling water from causing erosion damage to the flatbed transport vehicle 4, the rail track 3 and the rail roadbed 2, improving the reliability of the device operation and reducing maintenance costs.

[0020] In specific implementation, as a preferred configuration, the aforementioned U-shaped spray component includes a mounting frame 18, a U-shaped water guide pipe 19, a spray water injection pipe 20, and spray heads. The mounting frame 18 is installed inside the spray chamber 1. The U-shaped water guide pipes 19 are arranged sequentially along a rectangular array on the mounting frame 18. The spray water injection pipes 20 are evenly installed on the inner sidewalls of the U-shaped water guide pipes 19. Spray heads 21 are installed on one end of the spray water injection pipes 20. The cooling water supply mechanism includes a liquid supply pump 22, a main water supply pipe 23, and a branch water pipe 24. The inlet end of the liquid supply pump 22 is connected to the cold water tank 17. One end of the main water supply pipe 23 is connected to the outlet end of the liquid supply pump 22. The branch water pipe 24 is installed inside the spray chamber 1 and located on the mounting frame 1. Above 8, the inlet end of the water distribution pipe 24 is connected to the main water supply pipe 23, and each outlet end of the water distribution pipe 24 is connected to the U-shaped water guide pipe 19. An electromagnetic flow valve 25 is installed at the connection position between the water distribution pipe 24 and the U-shaped water guide pipe. When in use, the liquid supply pump 22 is started to draw out the cooling water from the cold water pool 17 and further supply it to the water distribution pipe 24 through the main water supply pipe 23. Then, the cooling water is injected into each U-shaped water guide pipe through the water distribution pipe 24, and further sprayed out through the spray water injection pipe 20 and nozzle connected to the side wall of the U-shaped water guide pipe, thereby realizing the synchronous spray cooling effect on the three exposed surfaces of the ferromolybdenum alloy ingot, increasing the spray coverage area and improving the cooling operation efficiency.

[0021] In the specific implementation process, as a preferred configuration, the top of the spray room 1 is equipped with a condenser fan 26. The outlet end of the condenser fan 26 is connected to the cold water pool 17 through the condenser pipe 27. During the contact between the cooling water and the high-temperature alloy ingot, a large amount of water vapor will be generated. At this time, the condenser fan 26 can be used to quickly discharge the water vapor, which reduces the impact of water vapor on the interior of the spray room 1. At the same time, the condensed water can be directly returned to the cold water pool 17, reducing the waste of water resources and reducing the overall energy consumption of the device.

[0022] In the specific implementation process, as a preferred setting, a water replenishment pipe 28 is set on one side of the above-mentioned cold water pool 17. In actual operation, some water will inevitably be lost. In order to ensure the stability of cooling operation, cold water is regularly replenished into the cold water pool 17 through the water replenishment pipe 28, which can further improve the operating efficiency of the device.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
