Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature volatilization furnaces, and particularly relates to a slag discharging mechanism for a germanium high-temperature volatilization furnace. Background Technique

[0002] When the volatilization furnace blows air equipped with pulverized coal into the germanium-containing material in a high-temperature molten state, a reducing atmosphere is formed in the furnace. Germanium dioxide in the molten slag is reduced to volatile germanium oxide in the reducing atmosphere and enters the furnace gas, and germanium is enriched in the soot collected from the furnace gas. By utilizing these characteristics of germanium sulfide and low-valent oxides, the atmosphere and temperature in the furnace are controlled to make it sublimate and volatilize first, and be enriched in the soot for recovery.

[0003] During the operation of the germanium volatilization furnace, it is necessary to continuously discharge the high-temperature molten furnace slag, that is, it flows into the slag tank through the slag discharging port on the lower side of the furnace, and then is quenched with high-pressure cold water. After slag fishing, it is sent to the storage yard. However, there will be multiple molten slags remaining in the slag material combustion, and during the combustion of the molten slag, it will remain in the structure of the volatilization furnace, and the remaining molten slag is difficult to be discharged with the finished product in the combustion furnace, resulting in poor discharge of some molten slags.

By introducing cooling water into the water guiding groove, the rotating first receiving plate can promote the cooling of the dripping molten slag under the dual action of air cooling and water cooling, thereby avoiding the adhesion of molten slag.

[0009] Preferably, water deflecting plates are fixedly connected to the bottom ends of the top plate and the rotating frame. The water deflecting plates are located inside the water guide groove. Pressure increasing grooves are formed on the surfaces of the water deflecting plates.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] The present utility model provides a slag discharge mechanism of a germanium high-temperature volatilization furnace as shown in Figures 1-4 which includes an outer shell 1. Inside the outer shell 1, there is a slag discharge cylinder 2. The slag discharge cylinder 2 includes a top plate 201 rotatably connected to the inside of the outer shell 1. The bottom end of the top plate 201 is fixedly connected to a rotating frame 202. Inside the rotating frame 202, three groups of first receiving plates 203 are fixedly connected. The inclined surfaces of the first receiving plates 203 facilitate the falling of molten slag. From top to bottom in the centers of the three groups of first receiving plates 203, there are successively arranged a first discharge port 204, a second discharge port 205, and a third discharge port 206. The diameters of the first discharge port 204, the second discharge port 205, and the third discharge port 206 decrease successively, so that the molten slag becomes smaller and smaller. On the outside of the first receiving plate 203, there is a water guide groove 207 and the water guide groove 207 is opened inside the outer shell 1. By introducing cooling water into the water guide groove 207, the rotating first receiving plate 203 can promote the cooling of the dripping molten slag under the dual actions of air cooling and water cooling, thereby avoiding the adhesion of molten slag. The surface of the first receiving plate 203 is fixedly connected with an anti-sticking coating 208. The anti-sticking coating 208 is made of aluminum oxide. The anti-sticking coating 208 further prevents the adhesion of liquid molten slag. Through the cooperation of the outer shell 1 and the slag discharge cylinder 2, the rotation of the top plate 201 and the rotating frame 202 drives the dispersion and cooling of the molten slag on the surface of the first receiving plate 203. At the same time, the contact between the water guide groove 207 and the cooling water accelerates the cooling of the molten slag. Finally, through the cooperation of the first discharge port 204, the second discharge port 205, and the third discharge port 206, the size of the molten slag is controlled to facilitate the discharge of the slag, so as to avoid the unsmooth discharge of the molten slag.

[0024] Refer to the attached drawings of the specification Figures 1-4, three groups of high-pressure water inlet pipes 3 are fixedly connected to one side of the outer shell 1. A filter ring 4 is installed on the side of the high-pressure water inlet pipe 3 away from the outer shell 1. An outlet pipe 5 is fixedly connected to the side of the outer shell 1 away from the high-pressure water inlet pipe 3. The high-pressure water inlet pipe 3 is filtered by the filter ring 4, and cold water is introduced into the water guide groove 207 through the high-pressure water inlet pipe 3. Water deflectors 10 are fixedly connected to the bottom ends of the top plate 201 and the rotating frame 202. The water deflectors 10 are located inside the water guide groove 207. Pressure-increasing grooves 9 are formed on the surfaces of the water deflectors 10. The cooperation of the water deflectors 10 causes the cold water to impact the water deflectors 10, driving the top plate 201 and the rotating frame 202 to rotate. A slag discharge pipe 6 is fixedly connected to the bottom end of the outer shell 1. A wrapping cylinder 8 is fixedly connected to the bottom end of the slag discharge pipe 6. Molten slag is introduced into the interior of the wrapping cylinder 8 through the slag discharge pipe 6. A servo motor 7 is fixedly connected to the bottom end of the wrapping cylinder 8. A screw conveyor 11 is fixedly connected to the output end of the servo motor 7. The servo motor 7 drives the screw conveyor 11 to discharge the molten slag. Through the cooperation of parts such as the high-pressure water inlet pipe 3, the filter ring 4, and the pressure-increasing groove 9, cooling water is introduced into the interior of the water guide groove 207 through the high-pressure water inlet pipe 3, and the cooling water is filtered by the filter ring 4. At the same time, the cooling water impacts the water deflector 10 and the pressure-increasing groove 9 amplifies the impact force of the cooling water on the water deflector 10, thereby driving the top plate 201 and the rotating frame 202 to rotate.

[0025] The working principle of this utility model:

[0026] Refer to the attached instruction manual Figures 1-4 , when the germanium high-temperature volatilization furnace is smelting, it is connected to the high-temperature volatilization furnace through the top plate 201, and the falling molten slag is received by the cooperation of the rotating frame 202 and the first receiving plate 203. When the slag discharge cylinder 2 receives the molten slag, cooling water is introduced into the interior of the water guide groove 207 through the high-pressure water inlet pipe 3 to exchange heat with the water guide groove 207. The cooling water is filtered by the filter ring 4. At the same time, the cooling water impacts the water deflector 10 and the pressure-increasing groove 9 amplifies the impact force of the cooling water on the water deflector 10, thereby driving the top plate 201 and the rotating frame 202 to rotate. The cooling water finally drains out of the interior of the slag discharge cylinder 2 through the outlet pipe 5. During this process, the rotation of the top plate 201 and the rotating frame 202 drives the molten slag on the surface of the first receiving plate 203 to disperse and cool. At the same time, the contact between the water guide groove 207 and the cooling water accelerates the cooling of the molten slag. Finally, the size of the molten slag is controlled through the cooperation of the first discharge port 204, the second discharge port 205, and the third discharge port 206 to facilitate the discharge of the molten slag into the interior of the wrapping cylinder 8 to avoid unsmooth discharge of the molten slag. Finally, the servo motor 7 is started to drive the screw conveyor 11 to discharge the molten slag.

[0027] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
