[0002] Vanadium slag roasting is a key process for extracting vanadium. Its core lies in converting low-valence vanadium in vanadium slag into soluble high-valence vanadium compounds through a high-temperature oxidation reaction. During roasting, the uniformity and controllability of oxygen distribution directly affect reaction efficiency, product quality, and energy consumption. In the vanadium slag roasting process, the uniformity and controllability of gas distribution have a critical impact on roasting efficiency and vanadium extraction rate.

[0003] Traditional gas distribution devices mostly adopt a fixed structure, using simple pipe openings or perforated plates to transport gas. It is difficult to flexibly adjust the gas flow and distribution according to the actual needs of the roasting process. This fixed gas input method easily leads to uneven oxygen concentration distribution in the roasting furnace, affecting the roasting efficiency of vanadium slag. Therefore, it is necessary to design a rotary multi-layer gas distribution device for vanadium slag roasting to solve the above problems. Utility Model Content

A limit component is installed between the inside of the gas supply pipe and the movable plate. A support plate is installed on one side of the inside of each of the two sets of gas supply pipes. An electric fan is installed inside each of the two sets of support plates.

[0007] Preferably, the limiting component includes a movable groove, a movable plate, and a fixing member. The movable groove is opened at one end of the outer side of the gas pipeline, the movable plate is installed at one end of the outer side of the movable plate and moves inside the movable groove, and the fixing member is installed between the movable groove and the movable plate.

[0008] Preferably, the fixing component includes a slot and an elastic plate. Multiple sets of slots are respectively opened on both sides of the interior of the movable slot, and two sets of elastic plates are respectively installed on both sides of the movable plate and the elastic plates can be engaged in two sets of slots.

[0009] Preferably, a filter screen is installed at one end of each of the two sets of gas pipelines, and the two sets of filter screens intercept impurities.

[0010] Preferably, two sets of support platforms are installed at the bottom of the interior of the roasting furnace, and multiple sets of support rods are installed between the two sets of support platforms. A support frame is installed at the top of the interior of the roasting furnace.

[0011] Preferably, a collection tray is slidably connected to the bottom of the roasting furnace, with one end of the collection tray located outside the roasting furnace, and a pull rod is installed on one side of the collection tray.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By opening the electric fan installed inside the support plate on one side of the gas supply pipe, air is blown into the roasting furnace through the gas supply pipe.

The heat insulation pipe installed on the outside of the roasting furnace reduces the temperature of the gas supply pipe.

[0014] 2. By pulling the movable plate within the movable slot, the movable plate moves the movable plate, which in turn moves the internally installed rotating plate, squeezing the two sets of elastic clamping plates.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a rotary multi-layer gas distribution device for vanadium slag roasting, including a roasting furnace 1. Two sets of heat insulation pipes 2 are installed in a ring at both ends of the outer side of the roasting furnace 1. Gas transmission pipes 3 are installed at one end of each of the two sets of heat insulation pipes 2. Circular baffles 4 are installed at one end of each of the gas transmission pipes 3.

[0022] Each of the two sets of air supply pipes 3 has a sliding groove 5 at one end. The sliding grooves 5 are slidably connected to the interior of each set of sliding plates 7. The movable plates 7 are installed inside the interior of each set of movable plates 7 and are attached to one side of the circular baffle 4. The interior of the circular baffle 4 and the movable plates 6 have multiple sets of through holes 8 arranged in a ring. A limit component is installed between the interior of the air supply pipe 3 and the movable plate 7. The interior of each of the two sets of air supply pipes 3 has a support plate 9 installed on one side. The interior of each of the two support plates 9 has an electric fan 10 installed inside.

[0023] Specifically, by opening the electric fan 10 installed inside the support plate 9 on one side of the gas supply pipe 3, air is blown from the gas supply pipe 3 into the roasting furnace 1. The limiting component is released, causing the rotating plate 6 to drive the movable plate 7 installed on the outside to rotate in the sliding groove 5 opened inside the gas supply pipe 3. By utilizing the through hole 8 opened between the rotating plate 6 and the circular baffle 4, the size of the overlap between the rotating plate 6 and the through hole 8 of the circular baffle 4 is used to adjust the amount of air entering the roasting furnace 1 from the gas supply pipe 3, thereby controlling the oxygen distribution in the roasting furnace 1. The heat insulation pipe 2 installed on the outside of the roasting furnace 1 reduces the temperature of the gas supply pipe 3.

[0024] The limiting component includes a movable groove 12, a movable plate 13, and a fixing member. The movable groove 12 is located at one end of the outer side of the gas supply pipe 3. The movable plate 13 is installed at one end of the outer side of the movable plate 7 and moves inside the movable groove 12. The fixing member is installed between the movable groove 12 and the movable plate 13. By pulling the movable plate 13 to move within the movable groove 12, the movable plate 13 drives the movable plate 7 to move, which in turn drives the rotating plate 6 installed inside the movable plate 7 to move. After the movement, the fixing member installed between the movable groove 12 and the movable plate 13 fixes the movable plate 13.

[0025] The fixing component includes a slot 14 and an elastic plate 15. Multiple slots 14 are respectively opened on both sides of the interior of the movable slot 12. Two sets of elastic plates 15 are respectively installed on both sides of the movable plate 13 and the elastic plates 15 can be engaged in two of the slots 14. By squeezing the two sets of elastic plates 15, the elastic plates 15 are disengaged from the slots 14, which can pull the movable plate 13 to move. The elasticity of the elastic plates 15 moves into the slots 14 to limit the movement of the movable plate 13.

[0026] Among them: one end of each of the two sets of gas supply pipes 3 is equipped with a filter screen 11, and the two sets of filter screens 11 intercept impurities.

[0027] Among them: two sets of support platforms 16 are installed at the bottom of the interior of the roasting furnace 1, and multiple sets of support rods 17 are installed between the two sets of support platforms 16. A support frame 18 is installed at the top of the interior of the roasting furnace 1. The material to be burned is placed on the top of the multiple sets of support rods 17 installed between the two sets of support platforms 16.

[0028] Wherein: a collection tray 19 is slidably connected to the bottom of the roasting furnace 1, and one end of the collection tray 19 is located outside the roasting furnace 1. A pull rod 20 is installed on one side of the collection tray 19. The collection tray 19 is located at the bottom of the roasting furnace 1 to collect the impurities after combustion. Pulling the pull rod 20 will move the collection tray 19.

[0029] Working Principle: This utility model provides a rotary multi-layer gas distribution device for vanadium slag roasting. When the gas supply pipe 3 is turned on, an electric fan 10 installed inside a support plate 9 on one side blows air into the roasting furnace 1, compressing two sets of elastic clamping plates 15. This causes the elastic clamping plates 15 to disengage from the clamping slots 14, allowing the moving plate 13 to move. The moving plate 13 moves within the movable slot 12, driving the movable plate 7 to move. The movable plate 7 then drives the internally installed rotating plate 6 to move, which in turn drives the external rotating plate 6 to move. The movable plate 7 installed on the side rotates in the groove 5 opened inside the gas supply pipe 3. By utilizing the through hole 8 opened between the rotating plate 6 and the circular baffle 4, the size of the overlap between the rotating plate 6 and the through hole 8 of the circular baffle 4 is used to adjust the amount of gas entering the roasting furnace 1 from the gas supply pipe 3, thereby controlling the oxygen distribution in the roasting furnace 1. The elastic plate 15 is used to move into the slot 14 to limit the moving plate 13 and prevent the rotating plate 6 from rotating. The contents not described in detail in this description are prior art known to those skilled in the art.
