[0003] When the existing slag separation device in front of a ferroalloy submerged arc furnace is in use, it is necessary to divert the slag. However, when diverting the slag, the slag tends to gather together, which easily leads to uneven diversion. As a result, when cooling the slag subsequently, too much slag directly contacts water, generating too much water vapor. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, due to the uneven diversion of the existing slag separation device in front of a ferroalloy submerged arc furnace, a large amount of water vapor is generated when contacting water during subsequent cooling. A slag separation device in front of a ferroalloy submerged arc furnace is proposed.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, the simultaneous operation of two vibration motors drives the support plate to vibrate. The vibration motors generate exciting forces, so that the materials in the slag separation device in front of the furnace are continuously vibrated, which helps to accelerate the relative movement between the materials, promotes the effective separation of slag and alloy, and can avoid the blockage of slag from affecting subsequent diversion.

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figure 1 、 Figure 2 shown, the present utility model provides a slag separation device in front of a ferroalloy submerged arc furnace, including a bottom plate 1. Four support columns 2 are fixedly installed on the top of the bottom plate 1. A housing 3 is fixedly installed on the top of the four support columns 2. A first square hole 4 is opened on one side of the outer wall of the housing 3. A heat dissipation plate 5 is fixedly installed on the inner surface wall of the first square hole 4. Two holes 6 are opened on the outer surface wall of the housing 3. Two hydraulic cylinders 7 are fixedly installed on the outer surface wall of the housing 3. The output ends of the two hydraulic cylinders 7 are both provided with piston rods 8. Push plates 9 are fixedly installed on the outer surface walls of the two piston rods 8. A diversion plate 10 is fixedly installed on one side of the outer wall of the housing 3. A group of partition plates 11 are fixedly installed on the top of the diversion plate 10. Two vibration motors 12 are fixedly installed on the bottom of the inner wall of the housing 3. A support plate 13 is fixedly installed between the tops of the two vibration motors 12.

[0024] The overall effect achieved by the entire Embodiment 1 is as follows. First, the two vibration motors 12 are connected to the support plate 13. When the slag is put on the support plate 13, the two vibration motors 12 operate to drive the support plate 13 to vibrate, which can make the slag evenly distributed on the slag separation device, avoiding the situation of excessive local load. This physical vibration effect helps the flow and distribution of the slag in the furnace, making it easier for the slag to be separated from the alloy. Secondly, the two hydraulic cylinders 7 are connected to the push plates 9 through the two piston rods 8. By operating the two hydraulic cylinders 7, the two piston rods 8 can be driven to expand and contract, and finally drive the push plates 9 to move, so as to push the slag to one side and make it enter the diversion plate 10. The slag is diverted by a group of partition plates 11, and the slag is dispersed between the multiple partition plates 11 below. The presence of the partition plates 11 changes the flow direction of the slag, making it flow along a predetermined path and reducing the risk of accumulation and blockage.

[0025] Embodiment 2, as Figures 1-4As shown in the figure, a square hole two 14 is provided on one side of the outer wall of the outer shell 3. Two hinges 15 are fixedly installed on the outer surface wall of the outer shell 3. A cabinet door 16 is fixedly installed between the outer surface walls of the two hinges 15. A water tank 17 is fixedly installed on the top of the bottom plate 1. A water injection pipe 18 is fixedly connected to the top of the water tank 17. A pipeline 19 is fixedly connected to the top of the water tank 17. A water pump 20 is arranged at the bottom of the pipeline 19. Two fixing rings 21 are fixedly installed on the outer surface wall of the pipeline 19. A group of spray heads 22 are fixedly connected to the bottom of the pipeline 19.

[0026] The effect achieved by the entire embodiment 2 is that when the device is in normal use, first, the two hinges 15 are connected to the cabinet door 16, and the cabinet door 16 can be freely opened and closed through the two hinges 15. Secondly, the pipeline 19 is fixed through the two fixing rings 21. At the same time, the water tank 17 is fixedly connected to the pipeline 19, and the pipeline 19 is fixedly connected to a group of spray heads 22. When the water pump 20 operates, water can be pumped from the water tank 17 to the pipeline 19 and then sprayed out through the spray heads 22 to cool the slag. Moreover, the amount of dust generated by the cooled slag will be greatly reduced. When the spray heads 22 spray liquid on the slag, part of the dust will be adsorbed and settled by the liquid, thereby reducing the dust content in the air.

[0027] Among them, the hydraulic cylinder 7, the vibration motor 12, and the water pump 20 are all prior arts. Their components and working principles are all public technologies and will not be explained in detail here.

[0028] Working principle: First, when the device is in normal use, two vibration motors 12 are fixedly installed at the bottom of the inner wall of the outer shell 3. A support plate 13 is fixedly installed between the tops of the two vibration motors 12. The slag falls onto the support plate 13. At this time, when the two vibration motors 12 operate simultaneously, they can drive the support plate 13 to vibrate. The vibration can keep the slag and molten iron in a flowing state, avoiding solidification and accumulation, ensuring the unobstructed flow of the slag separation device, greatly reducing the number of manual cleanings, reducing the labor intensity of workers, and improving the work safety at the same time. Secondly, one side of the outer wall of the outer shell 3 is fixedly connected to the drainage plate 10. The top of the drainage plate 10 is fixedly connected to a group of partition plates 11, which can carry out shunt treatment on the slag. A stable flow rate helps to improve the slag separation effect and stability, avoiding problems such as incomplete separation or equipment blockage caused by flow rate fluctuations. At the same time, two hinges 15 are fixedly installed on the outer surface of the outer shell 3. The two hinges 15 are connected to the cabinet door 16. Through the action of the hinges 15, the cabinet door 16 can be opened to repair the vibration motor 12. And a heat dissipation plate 5 is arranged on one side of the outer wall of the outer shell 3, which can timely discharge the heat generated when the vibration motor 12 operates to the outside. Secondly, two hydraulic cylinders 7 are fixedly installed on the outer surface of the outer shell 3. The output ends of the two hydraulic cylinders 7 are both provided with piston rods 8. The outer surfaces of the two hydraulic cylinders 7 are fixedly connected to the support plate 13. When the two hydraulic cylinders 7 operate simultaneously, they can drive the two piston rods 8 to stretch and retract, and finally drive the push plate 9 to push forward, pushing the slag towards the drainage plate 10, and then separated by the partition plates 11 and conveyed downward respectively. At the same time, a pipe 19 is fixedly communicated with the top of the water tank 17. A water pump 20 is arranged at the bottom of the pipe 19. When the water pump 20 operates, the water in the water tank 17 is pumped out and finally sprayed out from the nozzle 22 through the pipe 19. The fluidity of the slag after cooling may change, making it easier to flow and separate in the slag separation device, improving the accuracy and efficiency of slag separation. Spraying water on the shunted slag can reduce the amount of slag in contact with water for each part and reduce the generation of water vapor.

[0029] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
