Description

Technical Field

[0001] The utility model relates to the technical field of mixer blades, in particular to an impact-resistant submersible mixer blade. Background Art

[0002] A submersible mixer is a mechanical device capable of performing underwater mixing operations. Its core working principle is to use a motor to drive the rotation of the mixing blades or paddles, thereby generating a strong stirring force to fully mix the water or the substances in the water. The structure of a submersible mixer usually includes key components such as the motor, reducer, mixing blades, and sealing device. Among them, the motor provides power, the reducer adjusts the mixing speed to adapt to different working environments and mixing requirements, and the design of the mixing blades is directly related to the mixing effect. Therefore, their shape, size, and arrangement are carefully designed.

[0003] According to the Chinese patent publication number CN221310203U, an anti-corrosion mixer blade includes a fixed shaft with four blades arranged in an annular shape on the outside of the fixed shaft. The four blades are welded to the outer wall of the fixed shaft by a reinforcement block. An insulating vacuum chamber is provided in the middle of the reinforcement block. Two reinforcement support frames are cross-arranged inside the insulating vacuum chamber. The insulating vacuum chamber is in a vacuum state.

[0004] In the above scheme, only the corrosion resistance and fixing function of the blades are emphasized, but the impact resistance and wear resistance of the blades are poor. When facing strong water flow impact or sewage containing a large amount of solid particles, their impact resistance and wear resistance are relatively weak. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an impact-resistant submersible mixer blade, which solves the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A shock-resistant submersible mixer blade comprises: a fixing rod, on the outer circular wall of which three blades are fixedly mounted, two fixing blocks are respectively provided on both sides of the three blades, three threaded holes are opened on the top surfaces of the two fixing blocks, and the internal threads of the three threaded holes are connected with bolts; a reinforcement component, which is arranged on one side of the blade and is used to increase the strength of the blade.

[0008] By adopting the above technical solution, a fixed rod is set as the supporting structure of the blade to ensure the stability and reliability of the blade. The number of blades is specifically designed to be three. This design not only helps to form a uniform flow field and avoid the generation of dead corners and vortices, but also can improve the impact resistance of the blades to a certain extent, because the appropriate number of blades can reduce the impact area and impact force of the blades while ensuring the stirring efficiency. The fixed block further enhances the connection strength between the blades and the fixed rod, making the entire blade structure more stable, and the strengthening component effectively enhances the strength of the blades. This design can significantly improve the impact resistance of the blades, so that it can maintain the integrity and stability of the structure when facing strong water flow impact or solid particle collision.

[0009] Preferably, the reinforcement assembly includes: a reinforcement rib fixedly mounted on one side of the blade, the reinforcement ribs being arranged vertically and horizontally, a stainless steel layer being fixedly mounted on one side of the reinforcement rib, and glass fiber being fixedly mounted on the other side of the blade, the glass fiber being arranged vertically and horizontally.

[0010] By adopting the above technical solution, by arranging reinforcing ribs vertically and horizontally, this design effectively enhances the structural strength of the blades. The reinforcing ribs can absorb and disperse the stress generated by the blades when they are impacted, thereby preventing the blades from deformation or cracking. The stainless steel layer can effectively prevent the blades from corrosion and erosion. The addition of glass fiber also improves the fatigue resistance of the blades. Under long-term continuous operation, the blades are prone to fatigue damage, and the lightweight and high-strength characteristics of glass fiber can effectively reduce the fatigue of the blades and extend their service life.

[0011] Preferably, one side of the stainless steel layer is coated with an elastic coating.

[0012] By adopting the above technical solution, the elastic coating is provided with excellent elasticity, which can play a buffering role when the blade is impacted, reducing the direct damage of the impact force to the blade structure. This elastic characteristic enables the blade to maintain better structural integrity and stability when facing complex working conditions such as water flow impact and solid particle collision. The elastic coating usually has good adaptability and adhesion, and can fit tightly on the surface of the stainless steel layer to form a strong bond. This characteristic enables the elastic coating to maintain stable performance in a variety of environments and is not easy to fall off or be damaged.

[0013] Preferably, the surface of the elastic coating is coated with a wear-resistant coating, and the surface of the wear-resistant coating is fixedly mounted to the fixing block.

[0014] By adopting the above technical solution, by setting a wear-resistant coating directly on the elastic coating, double wear-resistant protection is provided for the blades. This design can significantly improve the wear resistance of the blade surface, enabling it to resist long-term water erosion, wear of solid particles and possible chemical corrosion.

[0015] Preferably, a titanium alloy layer is fixedly mounted on one side of the glass fiber.

[0016] By adopting the above technical solution, the overall strength and rigidity of the blades can be significantly improved by providing a titanium alloy layer, which enables the blades to maintain structural stability and integrity when subjected to large loads and pressures, thereby improving the operating efficiency and reliability of the submersible mixer.

[0017] Preferably, one side of the titanium alloy layer is coated with a hardened coating, the surface of the hardened coating is fixed to the fixed block, three liquid flow cavities are opened on one side of the hardened coating, the three liquid flow cavities penetrate the wear-resistant coating, and an isolation sleeve is fixedly installed inside the liquid flow cavity.

[0018] By adopting the above technical solution, the hardness and wear resistance of the titanium alloy layer surface can be significantly improved by setting a hardened coating. This hardening treatment enables the blades to maintain better surface integrity and service life when facing harsh working conditions such as water erosion and wear of solid particles. The design of the liquid flow cavity helps to reduce the heat of the blades and improve the heat dissipation performance. During the operation of the submersible mixer, the blades will generate a certain amount of heat. The liquid flow cavity can allow coolant or other fluids to pass through, thereby taking away heat and keeping the temperature of the blades within a reasonable range. The addition of an insulating sleeve can ensure the stability inside the cavity. The insulating sleeve can prevent the fluid from eroding and damaging the cavity wall, thereby enhancing the structural strength and durability of the blades.

[0019] In summary, the present invention has the following beneficial effects:

[0020] By using fixed rods as the core support structure of the blades, we ensure the stability and reliability of the blades during operation. In particular, the number of blades is carefully designed to be three. This layout not only helps to form a uniform flow field without dead angles and effectively avoids the generation of vortices, but also improves the impact resistance of the blades to a certain extent. While ensuring the mixing efficiency, the appropriate number of blades also reduces the impact area and impact force on each blade, thereby extending the service life of the blades. The introduction of fixed blocks further strengthens the connection between the blades and the fixed rods, making the entire blade structure more stable.

[0021] The ingenious design of the reinforcement components provides additional strength for the blades, significantly improving their impact resistance. Even when faced with powerful water impacts or solid particle collisions, the blades maintain structural integrity and stability. Furthermore, the longitudinal and transverse arrangement of the reinforcement ribs effectively enhances the blade's structural strength. These ribs absorb and disperse the stress generated by the blades during impact, thereby preventing deformation or cracking. The addition of the stainless steel layer provides excellent corrosion resistance, while the lightweight and high-strength properties of the glass fiber significantly improve the blade's fatigue resistance, extending its service life under long-term continuous operation. The elastic coating, with its excellent elastic properties, provides excellent cushioning when the blades are impacted, reducing direct damage to the blade structure caused by the impact. This coating adheres tightly to the stainless steel layer, forming a strong bond and maintaining stable performance in a variety of environments, making it difficult to fall off or damage. The wear-resistant coating is applied directly on the elastic coating, providing dual wear protection for the blades. This design significantly improves the wear resistance of the blade surface, enabling it to withstand long-term water erosion, abrasion by solid particles, and possible chemical corrosion.

[0022] The addition of the titanium alloy layer further enhances the overall strength and rigidity of the blade, which enables the blade to maintain structural stability and integrity when subjected to large loads and pressures, thereby improving the operating efficiency and reliability of the submersible mixer. The setting of the hardened coating significantly improves the hardness and wear resistance of the titanium alloy layer surface, enabling the blade to maintain better surface integrity and service life when facing harsh working conditions. The design of the liquid flow cavity not only helps to reduce the weight of the blade, but also improves its heat dissipation performance. During the operation of the submersible mixer, these cavities can allow coolant or other fluids to pass through, taking away the heat generated by the blades and keeping their temperature within a reasonable range. The addition of the insulating sleeve ensures the stability of the cavity interior and prevents the fluid from eroding and damaging the cavity wall, thereby further enhancing the structural strength and durability of the blade.
