Description

Technical Field

[0001] This utility model relates to the field of vanadium washing tank technology, and in particular to a mixer for vanadium washing tanks. Background Technology

[0002] In the hydrometallurgical process of vanadium, vanadium washing tanks are commonly used for stirring and washing vanadium-containing solutions. The agitator is the core equipment in the vanadium washing tank, and its stirring effect directly affects production efficiency and product quality. Currently, the agitators used in vanadium washing tanks typically employ an integrated or fixed stirring shaft design. This design has the following significant drawbacks in practical use:

[0003] First, when the mixer needs repair or parts replacement, especially for the mixing section deep at the bottom of the tank, it often requires complete disassembly, which is cumbersome, results in long downtime, and severely impacts production efficiency. Second, since different production batches or processes may use tanks of varying depths, a fixed-length mixing shaft cannot flexibly adjust the mixing height, leading to poor mixing results or requiring multiple mixers of different specifications, increasing equipment costs and management complexity. Therefore, a mixer for vanadium washing tanks is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a mixer for vanadium washing tanks to address the aforementioned technical problems. This mixer uses a connecting mechanism consisting of an upper extending boss, a lower extending boss, a connecting rod, upper / lower locking nuts, and a locking cylinder fitted onto the main stirring shaft to detachably connect the main and auxiliary stirring shafts. When only the bottom area of ​​the tank or the auxiliary stirring shaft needs maintenance, it is not necessary to completely remove the entire mixer from the tank. Simply loosen the first locking bolt on the main stirring shaft to release the locking cylinder, then unscrew the upper locking nut to lift the locking cylinder, separating the main stirring shaft from the connecting rod. The auxiliary stirring shaft can remain inside the tank or be removed separately, thus achieving quick and convenient separation of the main and auxiliary stirring shafts, significantly reducing maintenance workload and equipment downtime.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mixer for washing vanadium tanks includes a main mixing shaft and a secondary mixing shaft. An upper extending boss is fixed to the bottom of the outer side of the main mixing shaft, and a lower extending boss extends from the top of the outer side of the secondary mixing shaft. A connecting rod is fixed to the top of the lower extending boss. A lower locking nut is threaded to the middle of the connecting rod, and an upper locking nut is threaded to the top of the connecting rod. A locking cylinder is sleeved on the surface of the main mixing shaft, and the connecting rod passes through the locking cylinder and is threaded to the upper locking nut.

[0007] Furthermore, a hexagonal connecting post is slidably provided inside the main stirring shaft, and a hexagonal connecting groove that corresponds to and fits the hexagonal connecting post is provided inside the auxiliary stirring shaft.

[0008] Furthermore, both sides of the lower extension boss have clearance grooves, and fixed mounting seats are embedded in the clearance grooves.

[0009] Furthermore, the mounting base is internally threaded with a second locking bolt for engaging and locking with the hexagonal connecting post.

[0010] Furthermore, active stirring blades are fixed on the surface of the main stirring shaft, and multiple active stirring blades are distributed in an orderly manner along the outer side of the main stirring shaft.

[0011] Furthermore, a base is movably connected to the bottom end of the auxiliary stirring shaft, and a driven stirring blade is fixed to the outside of the base.

[0012] Furthermore, a stirring motor is fixedly connected to the top end of the main stirring shaft.

[0013] Furthermore, the outer side of the locking cylinder is threaded with a first locking bolt for contacting the main stirring shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The agitator for vanadium washing tanks provided by this utility model detachably connects the main agitator shaft and the auxiliary agitator shaft through a connecting mechanism consisting of an upper extending boss, a lower extending boss, a connecting rod, upper / lower locking nuts, and a locking cylinder sleeved on the main agitator shaft. When only the bottom area of ​​the tank or the auxiliary agitator shaft needs to be inspected, it is not necessary to completely lift the entire agitator out of the tank. Simply loosen the first locking bolt on the main agitator shaft to release the locking cylinder, and then unscrew the upper locking nut to lift the locking cylinder, separating the main agitator shaft from the connecting rod. The auxiliary agitator shaft can be left inside the tank or removed separately, thus achieving quick and convenient separation of the main and auxiliary agitator shafts, significantly reducing maintenance workload and equipment downtime.

[0016] The design of the connecting rod passing through the locking cylinder, along with the upper and lower locking nuts, forms a height adjustment mechanism. During assembly, the axial position of the secondary stirring shaft relative to the main stirring shaft can be fine-tuned by adjusting the length of the connecting rod passing through the locking cylinder on the secondary stirring shaft, i.e., changing the relative distance between the lower extension boss and the upper extension boss (or the locking cylinder). After confirming the required overall height, tightening the lower and upper locking nuts will securely lock the secondary stirring shaft at the preset height. This allows the same set of mixers to adapt to the stirring needs of vanadium washing tanks of different depths, improving the process adaptability and versatility of the equipment.

[0017] By incorporating a sliding hexagonal connecting post inside the main stirring shaft and a corresponding hexagonal connecting groove inside the auxiliary stirring shaft, circumferential positioning between the main and auxiliary stirring shafts can be achieved during connection, preventing relative rotation and ensuring effective power transmission from the main to the auxiliary stirring shaft. Furthermore, by installing a mounting seat within the clearance groove of the extended boss under the auxiliary stirring shaft and locking it to the hexagonal connecting post with a second locking bolt, the connection is laterally reinforced, preventing axial movement. This ensures that the split connection maintains extremely high rigidity and stability even under high-speed stirring conditions, guaranteeing both stirring performance and equipment operational safety.

[0018] The main stirring shaft features orderly distributed active stirring blades, while the auxiliary stirring shaft has driven stirring blades connected to its bottom via a base. This design creates two stirring zones, primary and secondary, enabling multi-level and more thorough mixing of the liquid within the tank. It is particularly suitable for vanadium washing processes where high solid-liquid mixing or mass transfer efficiency is required. A top-mounted stirring motor provides power, featuring a compact structure and direct drive. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] Example 1

[0030] Please refer to Figures 1-4 A mixer for washing vanadium tanks includes a main stirring shaft 1 and a secondary stirring shaft 2. An upper extending boss 11 is fixed to the bottom of the outer side of the main stirring shaft 1, and a lower extending boss 21 extends from the top of the outer side of the secondary stirring shaft 2. A connecting rod 22 is fixed to the top of the lower extending boss 21. A lower locking nut 23 is threaded to the middle of the connecting rod 22, and an upper locking nut 24 is threaded to the top of the connecting rod 22. A locking cylinder 3 is sleeved on the surface of the main stirring shaft 1, and the connecting rod 22 passes through the locking cylinder 3 and is threaded to the upper locking nut 24.

[0031] Because the agitator for the vanadium washing tank of this invention has the above structure, after the locking cylinder 3 passes through the connecting rod 22, the upper locking nut 24 and the lower locking nut 23 are tightened at the upper and lower ends respectively, so that the auxiliary agitator shaft 2 can be firmly connected to the lower part of the main agitator shaft 1. This makes the connection highly adjustable: by adjusting the length of the connecting rod 22 extending out of the locking cylinder 3, the relative axial position of the main and auxiliary agitator shafts can be changed to adapt to tanks of different depths.

[0032] Meanwhile, this connection method facilitates quick assembly and disassembly, providing a basis for subsequent maintenance and component replacement. During maintenance, it is not necessary to completely lift the entire mixer out of the tank; instead, the main and auxiliary mixing shafts can be disassembled for separate repairs.

[0033] Example 2

[0034] The agitator for the vanadium washing tank provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, a hexagonal connecting post 12 is slidably provided inside the main stirring shaft 1, and a hexagonal connecting groove 25 that is compatible with and fits the hexagonal connecting post 12 is provided inside the auxiliary stirring shaft 2.

[0035] Both sides of the lower extension boss 21 have clearance grooves 210, and a fixed mounting base 211 is embedded in the clearance grooves 210.

[0036] Because the agitator for the vanadium washing tank of this utility model has the above structure, the cooperation between the hexagonal connecting column 12 inside the main agitator shaft 1 and the hexagonal connecting groove 25 inside the auxiliary agitator shaft 2 achieves circumferential positioning and torque transmission of the non-circular cross section (hexagon) between the main and auxiliary shafts, effectively preventing relative rotation between the two during rotation, and ensuring that the power (transmitted from the agitator motor 14) can smoothly and without slippage drive the auxiliary agitator shaft 2 and the agitator blades at its bottom. The setting of the clearance groove 210 and the mounting base 211 reserves space and installation foundation for the subsequent auxiliary locking structure.

[0037] Example 3

[0038] The agitator for the vanadium washing tank provided in Example 1 or 2 is further optimized, such as... Figure 3 As shown, the mounting base 211 is internally threaded with a second locking bolt 212 for engaging and locking with the hexagonal connecting post 12.

[0039] Because the mixer for the vanadium washing tank of this utility model has the above structure, when the hexagonal connecting column 12 of the main stirring shaft 1 is inserted into the hexagonal connecting groove 25 of the auxiliary stirring shaft 2, and the second locking bolt 212 located in the mounting base 211 is tightened, the front end of the bolt will tightly abut against the side of the hexagonal connecting column 12. This lateral tightening force can effectively prevent the hexagonal connecting column 12 from accidentally loosening or coming out in the axial direction (especially when subjected to liquid impact or vibration), greatly enhancing the overall rigidity and stability of the split connection under dynamic working conditions, and ensuring the safe and reliable operation of the mixer under high-speed and heavy-load conditions.

[0040] Example 4

[0041] The agitator for the vanadium washing tank provided in Example 3 has been further optimized, such as... Figure 1 As shown, active stirring blades 13 are fixed on the surface of the main stirring shaft 1, and multiple active stirring blades 13 are distributed in an orderly manner along the outer side of the main stirring shaft 1.

[0042] The bottom end of the auxiliary stirring shaft 2 is movably connected to a base 26, and a driven stirring blade 27 is fixed on the outside of the base 26.

[0043] The top end of the main stirring shaft 1 is fixedly connected to a stirring motor 14.

[0044] Because the agitator used in the vanadium washing tank of this invention has the above structure, specifically, the stirring motor 14 drives the main stirring shaft 1 to rotate as a power source. The active stirring blades 13, which are arranged in an orderly manner on the main stirring shaft 1, constitute the upper main stirring zone, which strongly mixes the liquid in the upper part of the tank. The auxiliary stirring shaft 2 is driven to rotate by the main stirring shaft 1 through the aforementioned connection and locking mechanism, and its bottom end is connected to the driven stirring blades 27 through the base 26, which constitute the lower driven stirring zone. This main and driven zone design can perform multi-level and more uniform stirring of liquids at different depths in the vanadium washing tank, which is especially beneficial for breaking up sediment at the bottom of the tank, promoting full mixing and mass transfer of the solid and liquid phases, and improving the efficiency and uniformity of the vanadium washing process.

[0045] Example 5

[0046] The agitator for the vanadium washing tank provided in Example 4 has been further optimized, such as... Figure 3 As shown, the outer side of the locking cylinder 3 is threaded with a first locking bolt 31 for contacting the main stirring shaft 1.

[0047] Because the agitator used in the vanadium washing tank of this utility model has the above structure, during assembly, the locking cylinder 3 is first placed at a suitable height on the outside of the main stirring shaft 1, and then the first locking bolt 31 is tightened so that its front end tightly abuts against the surface of the main stirring shaft 1, thereby firmly fixing the locking cylinder 3 to the main stirring shaft 1. This step is a crucial preliminary step. After the connecting rod 22 passes through the locking cylinder 3, the upper locking nut 24 and the lower locking nut 23 can be rotated to lock the connecting rod 22 to the locking cylinder 3, ensuring the stability of the entire detachable connection mechanism. During disassembly, simply loosen the upper locking nut 24, the lower locking nut 23, and the first locking bolt 31 to release the locking cylinder 3, and then proceed with the subsequent separation operation, making the entire disassembly and assembly process logically clear and easy to operate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
