Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, specifically a homogenized reaction channel and a non-powered homogenized transmission fan. Background Technology

[0002] Homogenization in wastewater treatment refers to a process that uses physical, mechanical, or chemical methods to achieve a uniform distribution and mixing of pollutants, particulate matter, or chemical substances in wastewater within a solution. Its purpose is to ensure that the wastewater has a homogeneous composition and properties before subsequent treatment, thereby improving treatment efficiency and effectiveness. The core characteristics of homogenization are uniform mixing, prevention of sedimentation, promotion of reaction, and adaptation to subsequent processes, providing consistent influent conditions for later stages.

[0003] Many homogenization processes typically utilize a water tank and an electric mixer, or a mechanical blade in centrifuge tubes, to achieve homogenization. The disadvantages of using an electric mixer are: it requires a large reaction tank, wasting space; it consumes a large amount of electricity, wasting energy; the reaction tank is generally deep, making the medium prone to sedimentation and caking during the reaction, leading to difficult cleaning and maintenance; and ordinary mixing equipment is prone to wear and tear, loss of dynamic balance, and other common malfunctions due to long-term use of the medium, resulting in significant time, spare parts, and labor wastage for dismantling and repair. This directly leads to low equipment availability.

[0004] In summary, existing homogenization reaction systems have many shortcomings in terms of space utilization, energy consumption, maintenance difficulty, and equipment reliability. There is an urgent need for a new design that can improve equipment stability and maintenance convenience while saving space and energy, so as to meet the demands of modern water treatment processes for high efficiency and low cost.

When rotating by lever, it is the driving force generated by the flow rate of the fluid in the homogenizing reaction channel.

[0008] Furthermore, in this invention, the fan blade (305) is made of carbon fiber material.

[0009] Furthermore, in this utility model, the base (306) is made of cast iron with anti-corrosion treatment, and the base (306) is fixed to the inclined surface of the homogenized reaction channel by bolt connection.

[0012] Furthermore, in this utility model, the non-powered homogeneous transmission fan (3) is arranged in a long straight or S-shaped pattern in the channel body (1) to match the on-site working conditions, and the number and spacing of the transmission fans are determined according to the laying diameter and arrangement angle of the non-powered homogeneous transmission fan.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, a non-powered homogeneous drive fan 3 includes a lubrication-free central shaft 301, a bushing 302, an upper turntable 303, a lower turntable 304, fan blades 305, and a base 306. The bottom of the lubrication-free central shaft 301 is movably connected to the base 306. The lubrication-free central shaft 301 and the bushing 302 are made of self-lubricating materials or low-friction coatings, which can achieve smooth rotation without external lubricant. The bushing 302 is sleeved on the lubrication-free central shaft 301 and movably connected to the base 306 to support the stable rotation of the fan blades 305. It also has corrosion resistance and wear resistance, making it suitable for long-term operation in sewage treatment environments.

[0027] Specifically, the base 306 is made of cast iron with anti-corrosion treatment. The base 306 is fixed to the inclined surface of the homogenized reaction channel by bolts. A bushing 302 is fitted on the lubrication-free central rotating shaft 301. The upper rotating disk 303 and the lower rotating disk 304 rotate on the lubrication-free central rotating shaft 301 through the bushing 302. A fan blade 305 is arranged between the upper rotating disk 303 and the lower rotating disk 304. The fan blade 305 is wider at the top and narrower at the bottom.

[0028] The fan blades 305 are four in number, arranged symmetrically about the lubrication-free central shaft 301. This ensures the unpowered homogenizing drive fan maintains dynamic balance during rotation, reducing vibration and eccentric forces, thereby lowering equipment wear and failure rate. The even distribution of the four blades effectively captures the driving force generated by the fluid flow velocity within the homogenizing reaction channel, ensuring continuous and stable rotation of the drive fan and propelling the homogenizing process. The four-blade configuration creates multi-point turbulence within the reaction channel, increasing the mixing uniformity of the medium and improving reaction efficiency.

[0029] The upper fan blades, comprising 50%-80% of the cross-section, are used for rotation by leveraging force, while the lower fan blades, comprising 20%-50%, are used for homogenizing and mixing the medium. During rotation, the upper blades generate the driving force from the fluid flow velocity within the homogenizing reaction channel. The 50%-80% cross-section of the upper fan blades indicates a larger surface area, allowing for more efficient absorption of the driving force generated by the fluid flow velocity within the homogenizing reaction channel. According to fluid mechanics principles, the force exerted by the fluid on the fan blades is F = ρ·v. 2 ·A·C d Where ρ is the fluid density, v is the flow velocity, A is the area of ​​force application, and C is the surface area of ​​the fluid. d The drag coefficient is denoted by A. A larger cross-sectional area A allows the upper fan blades to capture more fluid kinetic energy, generating a greater thrust torque.

[0030] This design creates a lever effect. The upper blades, located in the upper part of the drive fan and farther from the central axis, form a longer lever arm. According to the torque formula M = F·L, where L is the length of the lever arm, the larger lever arm makes it easier for the driving force of the upper blades to be converted into rotational torque, thus driving the entire drive fan to rotate. Simultaneously, the wide design of the upper blades effectively guides fluid flow, reduces turbulence losses, and concentrates fluid energy into mechanical rotational energy. This design is similar to wind turbine blades, utilizing fluid kinetic energy to achieve unpowered drive.

[0031] The lower blade section accounts for 20%-50% of the total cross-section, with a smaller area, making it suitable for generating localized turbulence and shear force in the medium. According to fluid mechanics, the high-speed turbulence generated by the smaller blades during rotation can effectively break up agglomerated particles in the medium, promoting mixing and reaction. The stirring effect depends on the linear velocity of the blades and the intensity of the turbulence, rather than on the large area of ​​force applied; therefore, a cross-sectional area of ​​20%-50% is sufficient to achieve homogeneous stirring.

[0032] The narrow design of the lower fan blades reduces sedimentation resistance, decreasing the surface area in contact with the medium and thus reducing the resistance caused by sedimentation or caking. According to Newton's law of internal friction, resistance... Where A is the contact area and η is the viscosity of the medium, a smaller area A reduces resistance, preventing deposits from adhering to the blades and hindering rotation. It optimizes shear force; the narrow shape of the lower blades generates higher local fluid shear force during rotation, promoting particle dispersion and homogenization in the medium. This design is similar to the high-speed stirring blades in an agitator, suitable for the fine mixing required for homogeneous reactions.

[0033] In this embodiment, the fan blade 305 is made of carbon fiber. Carbon fiber is characterized by high strength and low density, making the fan blade lightweight, requiring less driving force during rotation, reducing fluid flow resistance, and improving the rotational efficiency of the non-powered fan. Carbon fiber exhibits excellent corrosion resistance to acidic, alkaline, or saline corrosive media in wastewater treatment, extending the service life of the fan blade in harsh environments and reducing replacement frequency. The smooth and wear-resistant surface of carbon fiber prevents wear or deformation during long-term contact with the medium, maintaining the dynamic balance and mixing effect of the fan blade and reducing equipment failure rate. The high modulus of carbon fiber makes the fan blade less prone to deformation during high-speed rotation or fluid impact, ensuring the stability of the upper fan blade's rotation by force and the lower fan blade's homogeneous mixing. The lightweight carbon fiber fan blade reduces rotational resistance, optimizes the utilization efficiency of fluid kinetic energy, eliminates the need for external power drive, reduces energy consumption, and the material itself is environmentally friendly with no pollution risk.

[0034] A homogenized reaction channel includes the aforementioned non-powered homogenized drive fan. The homogenized reaction channel includes a channel body 1, which is constructed of corrosion-resistant materials or anti-corrosion concrete to ensure long-term stable operation of the channel body in the corrosive environment of wastewater treatment and prevent structural damage caused by corrosion from media such as acidic, alkaline, or saline wastewater. It is suitable for various wastewater treatment scenarios and requires no frequent material adjustments.

[0035] The bottom slope 2 of the channel 1 has a gradient of 5°-30°. This homogenizing reaction channel, used in conjunction with a non-powered homogenizing drive fan 3, is employed in a water treatment reaction system to achieve homogenization and reaction of the medium. The slope design guides the fluid to flow naturally, utilizing gravity to assist the medium's movement, reducing fluid stagnation and sedimentation. Optimized fluid flow rate provides sufficient driving force for the non-powered homogenizing drive fan, promoting stirring and homogenization effects.

[0036] The slope range of 5°-30° has been optimized through testing to ensure sufficient fluid velocity to drive the drive fan while avoiding excessively steep slopes that could cause rapid fluid erosion and affect reaction time. The sloping design reduces media deposition and caking at the bottom of the channel, decreasing cleaning frequency and improving operational efficiency. Gravity-driven fluid flow eliminates the need for additional pumping power, reducing energy consumption. The slope range adapts to different throughput and media viscosity conditions and can be adjusted according to site requirements.

[0037] The channel guides the fluid flow, while the drive fan generates turbulence through blade rotation, both working together to achieve uniform mixing of the medium and improve reaction efficiency. The non-powered drive fan is driven by fluid velocity, requiring no electricity, significantly reducing energy consumption and carbon emissions. The drive fan's simple structure, combined with the corrosion-resistant channel, reduces potential failure points and maintenance workload. The optimized design of the channel and drive fan improves the water treatment process, allowing the treated medium to directly enter the next stage of the system without additional intermediate equipment.

[0038] The upper turntable 303 and lower turntable 304 of the non-powered homogenizing drive fan 3 have diameters of 30%-40% of the width of the homogenizing reaction channel. Limiting the turntable diameter to match the channel width ensures that the fan blades effectively cover the fluid area within the channel, optimizing the rotational and agitation effects. Providing stable structural support ensures the fan blades are firmly connected between the upper and lower turntables, maintaining dynamic balance during rotation.

[0039] Furthermore, in this invention, the non-powered homogenizing drive fans 3 are arranged in a long straight or S-shaped pattern within the channel body 1 to match the on-site working conditions. The number and spacing of the drive fans are determined based on their laying diameter and arrangement angle. The drive fans are flexibly arranged according to on-site conditions such as site size and throughput, extending the fluid reaction path or saving space, thereby improving the homogenization effect. By optimizing the number and spacing of the drive fans, fluid turbulence and mixing uniformity are enhanced, ensuring a complete reaction.

[0040] Furthermore, in this invention, the homogenization reaction channel can be installed above the sedimentation tank or on the ground, allowing the treated medium to directly enter the next stage system. This provides a flexible installation method, adapting to different site conditions in wastewater treatment plants and enhancing system integration capabilities. It achieves seamless integration between homogenization treatment and subsequent processes, reducing transitional equipment and piping, and simplifying the process.

[0041] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
