Description

Technical Field

[0001] This application relates to the field of zinc oxide production equipment, and more specifically to a crucible furnace for zinc oxide production. Background Technology

[0002] There are two methods for producing zinc oxide: direct and indirect. The indirect method is as follows: materials containing zinc (such as zinc ingots, zinc slag, crude zinc, zinc ash, etc.) are placed in a melting crucible and heated to 600-700°C to melt. The melt is then introduced into an evaporation crucible at a temperature higher than 907°C (usually around 1000°C) to evaporate and form zinc vapor. After the zinc vapor is output, it is oxidized by oxygen in the air to produce zinc oxide. Subsequently, the zinc oxide particles are transported through a cooling conveyor pipe to a dust collection chamber for cyclone separation. The fine particles are then collected using a cloth bag to obtain the finished zinc oxide product.

[0003] In existing related technologies, the melting crucible and the evaporation crucible are connected by a pipe. However, the connection between the pipe and the melting crucible is located at the top of the melting crucible, and the connection between the pipe and the evaporation crucible is located at the top of the evaporation crucible. This means that the liquid level of molten zinc oxide in the melting crucible needs to be kept at a high level to ensure that molten zinc oxide always flows through the pipe into the evaporation crucible. Therefore, operators need to add materials frequently, which increases their workload. Utility Model Content

[0004] To overcome the problem that the existing technology requires frequent material additions, which increases the workload of operators, this application provides a crucible furnace for zinc oxide production.

[0005] This application adopts the following technical solution: a crucible furnace for zinc oxide production, including a furnace body and a melting crucible and an evaporation crucible disposed on the top of the furnace body, wherein the melting crucible and the evaporation crucible are connected by a guide pipe, and further includes a movable platform, wherein the top of the platform is provided with a high-level slide rail;

[0006] A baffle that can slide on the high-position slide rail, and the baffle is provided with a sliding groove;

[0007] An expander has a handle on the side facing the baffle. The handle passes through the groove and can slide within the groove. A gas pipe passes through the handle and is used to supply gas into the expander. The expander can be inserted into the melting crucible.

[0008] Optionally, the platform includes a top plate, a bottom plate, and a low-position slide rail. The low-position slide rail is located on top of the bottom plate, and a support is provided between the bottom plate and the top plate. The support can slide on the low-position slide rail.

[0009] Optionally, the chute is inverted J-shaped. When the handle is located at the hook portion of the chute, the expander is located above the top plate. When the handle is located at the end of the vertical portion of the chute, the expander is located inside the melting crucible.

[0010] Optionally, the expander is arc-shaped, and the outer wall of the expander facing the baffle can fit against the inner wall of the melting crucible. The height of the expander is greater than the depth of the melting crucible.

[0011] Optionally, the expander includes a fixed part, a movable part, and an expander. The fixed part is used to fit against the inner wall of the melting crucible, and the expander is used to connect the fixed part and the movable part. One end of the gas pipe is connected to a gas source, and the other end of the gas pipe is connected to the expander. The movable part is used to push the material inside the melting crucible.

[0012] Compared with existing technologies, this application achieves the driving of the expander by moving the movable platform and baffle, and then uses the expander to expand its volume by inflating, thereby pushing the material in the molten crucible into the feed pipe without the need for frequent material addition, thus reducing the workload of the operator.

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] like Figure 1-4As shown, a crucible furnace for zinc oxide production includes a furnace body 1. An evaporation crucible 12 is provided at the center of the top of the furnace body 1. A melting crucible 11 is provided on both sides of the evaporation crucible 12. The two melting crucibles 11 and the evaporation crucible 12 are arranged in a straight line. The evaporation crucible 12 and the melting crucible 11 are connected by a guide pipe 13. The material in the evaporation crucible 12 can flow into the evaporation crucible 12 through the guide pipe 13.

[0020] A movable platform 2 is provided on both sides of the furnace body 1. The platform 2 includes a top plate 22, a bottom plate 23, and a low-position slide rail 24. The low-position slide rail 24 is located on top of the bottom plate 23. A support 25 is provided between the bottom plate 23 and the top plate 22. The support 25 can slide on the low-position slide rail 24. The length of the top plate 22 is greater than the length of the support 25. In this way, when the support 25 is moved into position, the top plate 22 can overlap the top of the furnace body 1, so that the expansion body 4 can more easily approach and be inserted into the melting crucible 11. A high-position slide rail 21 is provided on top of the top plate 22. A baffle 3 is adapted to be provided on the high-position slide rail 21, that is, the baffle 3 can slide smoothly on the high-position slide rail 21, thereby approaching or moving away from the furnace body 1. The baffle 3 is provided with a sliding groove 30, and a handle 41 is inserted into the sliding groove 30 of the baffle 3. One end of the handle 41 is located on the side of the baffle 3 away from the furnace body 1, and the other end of the handle 41 is located on the side of the baffle 3 close to the furnace body 1. An expansion body 4 is provided at the other end of the handle 41, and a gas pipe 42 is inserted into the handle 41. The gas pipe 42 is used to deliver gas into the expansion body 4, and the expansion body 4 can be inserted into the melting crucible 11.

[0021] The chute 30 is inverted J-shaped. When the handle 41 is located at the hook of the chute 30, the expander 4 is above the top plate 22. When the handle 41 is located at the end of the vertical part of the chute 30, the expander 4 is located inside the molten crucible 11. In other words, the position of the expander 4 can be adjusted by adjusting the position of the handle 41 within the chute 30. Furthermore, the operator can stand on the side of the baffle 3 away from the furnace body 1 to adjust the position of the expander 4. This effectively prevents burns from material splashing when the expander 4 is inserted into the molten crucible 11, thus improving operational safety. Additionally, the baffle 3 can be made of transparent material to ensure that it provides protection without obstructing the operator's view. The expander 4 is arc-shaped, and its outer wall facing the baffle 3 can fit against the inner wall of the molten crucible 11. The height of the expander 4 is greater than the depth of the molten crucible 11. This ensures that after the expander 4 is inserted into the molten crucible 11, the handle 41 is separated from the furnace body 1, making it easy to grip the handle 41 again and reset the expander 4. The expander 4 includes a fixed part 43, a movable part 44, and an expansion part 45. The fixed part 43 is used to fit against the inner wall of the molten crucible 11, and the expansion part 45 is used to connect the fixed part 43 and the movable part 44. One end of the gas pipe 42 is connected to the gas source, and the other end of the gas pipe 42 is connected to the expansion part 45. The movable part 44 is used to push the material in the molten crucible 11. That is, the expansion of the expander 4 can increase its own volume, thereby pushing the material in the molten crucible 11 into the feed pipe, thus eliminating the need for frequent material addition.

[0022] The working process of this application is as follows: After all the material in the melting crucible 11 has melted, the support 25 is pushed to move towards the furnace body 1. When the support 25 slides on the low slide rail 24 to a state of being in contact with the furnace body 1, the top plate 22 is in a state of overlapping the top of the furnace body 1. At this time, the operator stands behind the baffle 3 and pushes the baffle 3 to move towards the melting crucible 11. When the outer wall of the fixing plate of the expansion body 4 is above the melting crucible 11, the operator holds the handle 41 and moves it upward. In this way, the handle 41 can move from the curved part of the slide groove 30 to the vertical part of the slide groove 30.

[0023] When the handle 41 is moved into the vertical part of the slide groove 30, the handle 41 can slide downward. During this process, the expansion body 4 will move downward synchronously. When the handle 41 moves to the end of the vertical part of the slide groove 30, the expansion body 4 is just inserted into the bottom of the melting crucible 11. At this time, the fixing part 43 of the expansion body 4 is in contact with the inner wall of the melting crucible 11.

[0024] Once the expander 4 is inserted into place, an air pump or other air source can deliver gas to the expansion part 45 of the expander 4 through the air pipe 42, thereby causing the expansion part 45 to change from a contracted state to an expanded state. At this time, the movable part 44 will move towards the guide pipe 13, thereby slowly pushing the material in the molten crucible 11 into the guide pipe 13 and promoting the flow of the material.

[0025] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
