Description

Technical Field

[0001] This utility model relates to an intelligent, efficient and controllable phosphorus iron casting equipment, belonging to the field of aluminum electrolysis technology. Background Technology

[0002] The aluminum electrolytic cell is the main technical equipment for electrolytic aluminum production. It mainly consists of two parts: the bottom molten pool structure and the upper structure. The anode is one of the most crucial components of the upper structure, and it primarily includes the anode aluminum guide rod, aluminum-steel explosion welded blocks, anode steel claws, and anode carbon blocks.

[0003] The function of pig iron in the anode assembly process is to connect the new anode carbon block and the guide rod assembly together. The connection point is between the steel claw of the guide rod assembly and the bowl of the carbon block. Molten pig iron in the ladle is poured into the gap between the steel claw and the carbon bowl using a casting machine. After cooling, the guide rod assembly and the carbon block are combined into one piece and then transported to the electrolysis process for use.

[0004] Currently, the casting method used in production mainly involves a casting trolley combined with manual casting. The overall anode casting process is time-consuming, and casting cannot be done simultaneously in the four carbon bowls, increasing labor costs during aluminum electrolysis anode casting. Phosphorus iron casting is inefficient, and the safety of the process cannot be guaranteed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent, efficient, and controllable ferrophosphorus casting device. By adjusting the amount of compressed air introduced, the height of the ferrophosphorus liquid level in the tank can be achieved, thereby realizing the automatic casting of ferrophosphorus from the anode steel claws of the aluminum electrolysis cell. This enhances the intelligence of workshop equipment, reduces labor costs, and significantly improves the efficiency of ferrophosphorus casting by reducing manual operation. It also saves energy and reduces consumption while improving the safety of process operation, thus solving the problems of manpower and time consumption in the existing technology.

[0006] The technical solution of this utility model is: an intelligent, efficient and controllable phosphorus iron casting equipment, including a box body, wherein multiple independently arranged processing cavities with outward openings are formed on the inner side of the box body, and the processing cavities include a main cavity and a secondary cavity;

[0007] The discharge pipe is located on the upper end of one side wall of the box body and is in communication with the secondary inner cavity;

[0008] The unloading pipe is located at the lower end of one side wall of the box body and is connected to the main inner cavity;

[0009] A sealing assembly includes a support frame, a pressing cover, an adjusting rod, and a support block. The support frame is disposed on the upper end face of the housing and located at the opening of the main inner cavity. The adjusting rod is provided on the upper end face. One end of the adjusting rod passes through the support frame and is connected to the pressing cover. The pressing cover seals the upper opening of the main inner cavity.

[0010] A pneumatic pressurization port is located on the upper end face of the pressing cover and is connected to the main inner cavity.

[0011] Furthermore, the sealing assembly also includes a sealing pressure plate disposed between the pressing cover and the adjusting rod.

[0012] Furthermore, the main inner cavity and the secondary inner cavity are provided with baffles, and the lower end of the baffles forms a transition channel with the lower inner wall of the main inner cavity.

[0013] Furthermore, the end of the discharge pipe away from the box body is connected to a discharge pipe via a discharge flange.

[0014] Furthermore, the upper end face of the pressing cover is provided with a handle.

[0015] Furthermore, a through overflow hole is provided on the partition between two adjacent sub-cavities.

[0016] Furthermore, the enclosure is assembled from silicon carbonitride plates combined with refractory castables, nano-insulation boards, and ceramic fiber boards from the outside to the inside.

[0017] Furthermore, the bottom wall of the main inner cavity gradually slopes down from the discharge pipe to the unloading pipe, forming an inclined surface.

[0018] The advantages of this invention compared to existing technologies are as follows: The formed box is configured with multiple independent processing cavities, and each cavity is equipped with a corresponding discharge pipe and unloading pipe, ensuring that each cavity can operate independently. This novel controllable ferrophosphorus casting equipment can also adjust the amount of compressed air introduced through the pneumatic pressurization port on the pressure cover to control the ferrophosphorus liquid level within the box, thereby achieving automatic ferrophosphorus casting for the anode steel claws of the aluminum electrolysis cell. This enhances the intelligence of workshop equipment while reducing labor costs and significantly improving the efficiency of ferrophosphorus casting. It also saves energy and reduces consumption while improving the safety of process operations. Furthermore, the enclosed components ensure the airtightness of the main cavity during processing.

[0029] See Figure 1-7This utility model discloses a low-pressure environment vacuum interrupter power frequency withstand voltage testing device, comprising a housing 1, wherein the inner side of the housing 1 forms a plurality of independently arranged processing cavities with outward openings, the processing cavities including a main cavity 100 and a secondary cavity 101; a discharge pipe 2, which is disposed on the upper end of one side wall of the housing 1 and communicates with the secondary cavity 101; a discharge pipe 10, which is disposed on the lower end of one side wall of the housing 1 and communicates with the main cavity 100; and a pneumatic pressurization port 11, which is disposed on the upper end face of the pressing cover 6 and communicates with the main cavity 100.

[0030] In use, the main processing unit 1 is assembled from silicon carbonitride plates combined with refractory castables, nano-insulation boards, and ceramic fiber boards, forming a box body from the outside to the inside. Multiple independent processing cavities are formed inside, including a main cavity 100 and a secondary cavity 101. The preferred number of processing cavities is four sets, which simplifies manufacturing, reduces cost, and facilitates operation. The independent cavities ensure individual control of each cavity via an intelligent pneumatic control device. The main cavity 100 serves as the primary processing area, while the secondary cavity 101 serves as the processing adjustment area. Air can be supplied to the main cavity 100 via a pneumatic pressure port 11 located on the pressure cover 6. Adjusting the amount of compressed air allows the high-temperature ferrophosphorus liquid in the main cavity 100 to flow into the secondary cavity 101, thus achieving the correct ferrophosphorus liquid level within the box and enabling automatic ferrophosphorus casting for the anode steel claws of the aluminum electrolysis cell. The discharge pipe 2, located on the upper side wall of one side of the secondary inner cavity 101, has a certain distance from its lower end face, allowing the secondary inner cavity 101 to store more high-temperature ferrophosphide liquid. When it reaches the discharge pipe 2, the excess high-temperature ferrophosphide liquid is discharged through the discharge pipe 2. The unloading pipe 10 is located at the lower end of one side wall of the box body 1, facilitating the discharge of residue from the lower inner wall of the main inner cavity 100. A sealing assembly is provided in the main inner cavity 100, which includes a support frame 5, a pressing cover 6, an adjusting rod 8, and a support block 9. The support frame 5 is disposed on the upper end face of the housing 1 and located at the opening of the main inner cavity 100. The upper end face is provided with the adjusting rod 8. One end of the adjusting rod 8 passes through the support frame 5 and is connected to the pressing cover 6. The pressing cover 6 seals the upper opening of the main inner cavity 100. The adjusting rod 8 can be made into a bolt rod and threadedly engaged with the support frame 5. By screwing the adjusting rod 8, pressure is continuously applied to the pressing cover 6 to ensure the sealing of the opening of the main inner cavity 100 by the pressing cover 6.

[0031] In this specific example, the sealing assembly further includes a sealing plate 7 disposed between the pressing cover 6 and the adjusting rod 8. The sealing plate 7 serves as a transitional connector between the pressing cover 6 and the adjusting rod 8. The pressing cover 6 can be compressed simply by rotating the adjusting rod 8 to continuously press against the sealing plate 7. The pressing cover is equipped with a lifting handle 12 and has an air inlet flange and air inlet pipe that can be connected to a pneumatic control device to complete the pressurization operation of the separate cavities inside the box.

[0032] Specifically, the main inner cavity 100 and the secondary inner cavity 101 are provided with baffles 110. The baffles 110 and the inner bottom wall of the main inner cavity 100 have a certain distance to form a transition channel, which facilitates the amount of compressed air introduced into the inner side of the main inner cavity 100, so that the high temperature phosphorus iron liquid in the inner side of the main inner cavity 100 flows into the secondary inner cavity 101.

[0033] Specifically, the end of the discharge pipe 2 away from the box is connected to a discharge pipe 4 via a discharge flange 3. The discharge channel is extended by connecting the discharge pipe 4 to the discharge flange 3, which facilitates collection.

[0034] Specifically, an overflow hole 13 is provided through the partition between two adjacent secondary inner cavities 101. For safety reasons, when the high-temperature ferrophosphorus liquid inside the secondary inner cavity 101 exceeds the discharge pipe 2, it can be discharged into the adjacent cavity in time to avoid excessive splashing of high-temperature liquid.

[0035] Specifically, the bottom wall of the inner side of the main inner cavity gradually decreases from the discharge pipe 2 to the unloading pipe 10, forming an inclined surface so that the waste liquid can flow out of the unloading pipe 10 better.

[0036] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
