[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A clean production equipment for vanadium extraction from vanadium-bearing shale, featuring a waste gas purification filter, includes a production tank 1. A waste gas pipe 11 is fixedly connected to the surface of the production tank 1. Crushed vanadium-bearing shale is added to the production tank 1, followed by a sulfuric acid solution of a certain concentration. Through heating and stirring, the sulfuric acid is brought into full contact with the ore, resulting in a chemical reaction that leaches vanadium from the ore to form a vanadium-bearing solution. Parameters such as temperature, acid concentration, and stirring speed are controlled to optimize the leaching effect. The production tank 1 uses sulfuric acid to leach vanadium, generating waste gas containing dust and harmful gases. This waste gas is discharged through the waste gas pipe 11. A filter mechanism, including a replacement pipe 24, is fixedly connected to the surface of the waste gas pipe 11. A motor 2 is fixedly connected to the surface of the production tank 1, and a lead screw is fixedly connected to the output shaft of the motor 2. 21. A lifting rod 22 is threadedly connected to the surface of the lead screw 21. A top rod 23 is fixedly connected to the surface of the lifting rod 22. A cylindrical filter screen 26 is slidably connected to the surface of the replacement tube 24. A sealing gasket 25 is fixedly connected to the surface of the cylindrical filter screen 26. This filtration mechanism can automatically replace the cylindrical filter screen 26, saving time and effort while ensuring the production efficiency of the equipment. A collection mechanism is provided on the surface of the production tank 1. The collection mechanism includes a support rod 3, which is fixedly connected to the surface of the production tank 1. A collection box 31 is fixedly connected to the surface of the support rod 3. A discharge baffle 32 is fixedly connected to the surface of the replacement tube 24. A guide plate 33 is fixedly connected to the surface of the discharge baffle 32. This collection mechanism can collect the used cylindrical filter screen 26 on the collection box 31, thus facilitating the cleaning task for the staff.

[0024] Furthermore, the exhaust pipe 11 and the replacement pipe 24 are arranged in a cross shape. The interiors of the exhaust pipe 11 and the replacement pipe 24 are interconnected, so that the exhaust gas from the exhaust pipe 11 will pass through the connection with the replacement pipe 24. The cylindrical filter screen 26 at the connection of the replacement pipe 24 purifies the exhaust gas.

[0025] Furthermore, the motor 2 drives the lead screw 21 to rotate through the output shaft, and one side of the lifting rod 22 slides on the surface of the production tank 1 in an arc shape. The lead screw 21 drives the lifting rod 22 to slide on the surface of the production tank 1 through rotation. The motor 2 has a built-in self-locking mechanism, which can lock the rotation position of the lead screw 21 after rotation is completed. At this time, the lead screw 21 will also limit the height position of the lifting rod 22 on the production tank 1.

[0026] Furthermore, the lifting rod 22 drives the top rod 23 to slide and rise synchronously on one side of the production tank 1. The center of the top rod 23 and the center of the replacement tube 24 are on the same vertical line. The top rod 23 rises and falls vertically on one side of the production tank 1, always keeping it on the same vertical line as the replacement tube 24.

[0027] Furthermore, the cylindrical filter screen 26 is stacked inside the replacement tube 24 for continuous replacement. Two sets of sealing gaskets 25 are provided and distributed at the top and bottom of the cylindrical filter screen 26. The cylindrical filter screen 26 is sealed by the sealing gaskets 25 and the inner wall of the replacement tube 24. The sealing gaskets 25 are pressed against the inner wall of the replacement tube 24 by the cylindrical filter screen 26 to achieve a seal. The cylindrical filter screen 26 located at the junction of the exhaust pipe 11 and the replacement tube 24 filters the exhaust gas, while the two sets of sealing gaskets 25 on the cylindrical filter screen 26 prevent the exhaust gas from leaking into the replacement tube 24.

[0028] Furthermore, the diameter of the top rod 23 is smaller than the diameter of the replacement tube 24. The lifting rod 22 drives the top rod 23 to slide into the interior of the replacement tube 24. The top rod 23 supports multiple sets of cylindrical filter screens 26 inside the replacement tube 24. During the lifting and lowering process of the top rod 23, the position of multiple sets of cylindrical filter screens 26 is changed at the same time, realizing the replacement of the cylindrical filter screens 26 at the junction of the exhaust pipe 11 and the replacement tube 24.

[0029] Furthermore, the discharge baffle 32 is a flared shape with an inclined angle to prevent the cylindrical filter screen 26 from falling randomly from the top of the replacement tube 24. The discharge baffle 32 has a notch on the side away from the guide plate 33. The guide plate 33 is triangular in shape and guides the movement direction of the cylindrical filter screen 26. The collection box 31 is set on one side of the notch in the discharge baffle 32, and the height of the top of the collection box 31 is lower than the height of the notch in the discharge baffle 32. Under the guidance of the discharge baffle 32 and the guide plate 33, the cylindrical filter screen 26 falls onto the collection box 31, completing the automatic collection of the collection box 31.

[0030] Working principle: The cylindrical filter 26 at the junction of the exhaust pipe 11 and the replacement pipe 24 filters the exhaust gas. When the cylindrical filter 26 needs to be replaced, the output shaft of the motor 2 drives the lead screw 21 to rotate. The lead screw 21 rotates and raises the lifting rod 22. The lifting rod 22 lifts the cylindrical filter 26 stacked inside the replacement pipe 24 through the top rod 23, thereby changing the position of multiple sets of cylindrical filters 26 and realizing the replacement of the cylindrical filter 26 at the junction of the exhaust pipe 11 and the replacement pipe 24. In addition, the sealing gaskets 25 at the top and bottom of the cylindrical filter 26 prevent exhaust gas from leaking inside the replacement pipe 24. The filtration mechanism realizes automatic replacement of the cylindrical filter 26, saving time and labor while ensuring the production efficiency of the equipment.

[0031] The push rod 23 will push the cylindrical filter screen 26 out from the top of the replacement tube 24. When the cylindrical filter screen 26 is pushed out, the cylindrical filter screen 26 at the top of the replacement tube 24 will be restricted by the discharge baffle 32 and will move towards the notch of the discharge baffle 32 under the guidance of the guide plate 33. When the support surface at the bottom of the cylindrical filter screen 26 is insufficient, the cylindrical filter screen 26 will fall from the notch of the discharge baffle 32 onto the collection box 31, thereby realizing the automatic collection of the collection box 31 and facilitating the cleaning task of the staff.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
