[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0029] like Figure 1 As shown, a sewage mixing and treatment tank for sewage treatment according to this application includes a tank body 1, a drive shaft 2, a mixing blade 3, a cutting device 4, a protective cover 5, and a discharge valve 6. These components together constitute a highly efficient sewage treatment system.

[0030] Tank 1 is the foundation of the entire system, used to contain sewage. It has an inlet at the top for easy feeding of sewage into tank 1. The design of tank 1 needs to ensure sufficient volume and structural strength to withstand the weight and pressure of various types of sewage.

[0031] The drive shaft 2 is vertically installed inside the tank body 1. Its function is to transmit power, driving the entire stirring system by connecting to a power source such as a motor. The design of the drive shaft 2 must ensure sufficient rigidity and stability to prevent deformation or breakage due to excessive load.

[0032] The stirring blades 3 are mounted on the drive shaft 2 and are used to mix the manure in the tank 1. The number, shape, and layout of the blades directly affect the mixing effect. They are generally designed as multi-layered, multi-blade structures to improve mixing uniformity and treatment efficiency.

[0033] The cutting device 4 is fixed to the lower part of the drive shaft 2 and mainly consists of multiple cutters 41, used to chop large particles of impurities that enter the pool 1. The cutters 41 are designed to ensure sharp edges and wear resistance so that they can still effectively cut large particles during long-term use.

[0034] The protective cover 5 is fitted onto the outside of the drive shaft 2, located above the cutting device 4, to prevent large particles of impurities from directly contacting the drive shaft 2 and reducing the risk of entanglement. The protective cover 5 is generally made of metal, and its design must ensure that the gap between it and the drive shaft 2 is appropriate, effectively blocking impurities without affecting the normal operation of the drive shaft 2.

[0035] The discharge valve 6 is located at the bottom of the tank 1 and is used to discharge treated sewage. The discharge valve 6 must have good sealing performance and durability to ensure stable operation under high pressure, and be easy to open and close to control the sewage discharge process.

[0036] Specifically, the tank body 1 is typically constructed of reinforced concrete or metal to ensure structural strength and corrosion resistance. The drive shaft 2 is generally made of high-strength steel and undergoes heat treatment to improve its wear resistance and fatigue resistance. The agitator blades 3 can be made of stainless steel and designed in a spiral or multi-bladed fan shape to enhance the agitation effect. The cutter 41 of the cutting device 4 can be made of high-hardness alloy steel and finely ground to ensure sharpness. The protective cover 5 is also made of stainless steel and designed with a mesh or strip structure to both block large particles of impurities and allow liquid sewage to flow smoothly. The discharge valve 6 can be a ball valve or gate valve, using corrosion-resistant materials such as stainless steel or Teflon coating to ensure sealing and reliability.

[0037] The solution proposed in this application aims to address the problem that large, non-biodegradable particles, such as plastics and fibers, in sewage can become entangled on the drive shaft 2 during prolonged agitation, leading to decreased transmission efficiency and equipment jamming. By introducing a cutting device 4 and a protective cover 5, large particles are effectively cut and blocked before approaching the drive shaft 2, thus preventing these problems and improving system stability and service life. The cutting device 4 uses multiple layers of cutters 41 to shred large particles into smaller, more easily agitated particles, while the protective cover 5 further prevents residual materials generated during the shredding process from directly contacting the drive shaft 2, forming a dual protection mechanism that ensures the cleanliness and normal operation of the drive shaft 2.

[0038] In one embodiment, such as Figure 2As shown, the manure mixing and treatment tank of this application has several spiral guide plates 11 on the inner wall of the tank body 1. These guide plates extend from the top to the bottom along the inner wall of the tank body 1 in a spiral shape, so that the manure forms a spiral flow path from top to bottom during the mixing process, thereby reducing the residence time of large particles of impurities in the tank body 1 and avoiding their accumulation on the drive shaft 2. The height of the spiral guide plates 11 is 1 / 4 to 1 / 3 of the inner diameter of the tank body 1, which can effectively guide the flow of manure without causing excessive obstruction to the operating space in the tank body 1, ensuring efficient mixing and treatment of manure. In addition, a scraper 12 is provided on the outer edge of the spiral guide plate 11. The scraper 12 is inclined along the outer edge of the spiral guide plate 11. When the manure flows along the guide plate, the scraper 12 can scrape off the impurities attached to the inner wall of the tank body 1, further reducing the risk of entanglement.

[0039] For example, a spiral guide plate 11 can be installed starting from the top edge of the inner wall of the pool 1, ensuring it extends downwards along the inner wall of the pool 1 to the bottom of the pool 1. The shape and size of the spiral guide plate 11 should be precisely designed so that its height corresponds to 1 / 4 to 1 / 3 of the inner diameter, ensuring that it effectively guides the flow of sewage without affecting the operating space inside the pool 1. A scraper 12 can be installed on the outer edge of the spiral guide plate 11 using a fixing device, ensuring it is at a certain angle to effectively scrape away impurities adhering to the inner wall of the pool 1 during the flow of sewage.

[0040] In one embodiment, the drive shaft 2 of the sewage mixing tank for sewage treatment according to this application is made of high-strength stainless steel. This material possesses high mechanical strength, capable of withstanding the torque and shear forces generated during sewage treatment, ensuring the stability and reliability of the drive shaft 2 during long-term operation. Furthermore, the outer surface of the drive shaft 2 undergoes special treatment, using a specific process to make its surface smooth and improve its corrosion resistance. This treatment not only helps extend the service life of the drive shaft 2 but also effectively reduces the adhesion and entanglement of large particles of sewage on its surface, keeping the drive shaft 2 clean and operating efficiently.

[0041] Specifically, high-quality, high-strength stainless steel can be selected as the material for the drive shaft 2, and its surface can be made to achieve the desired smoothness through precision machining and polishing processes. For example, chemical polishing or physical polishing methods can be used during the production process to treat the drive shaft 2 to remove rough parts of the surface and improve its smoothness. At the same time, surface coating technology, such as spraying anti-rust coatings or using plating materials, can be used to further enhance the corrosion resistance of the drive shaft 2, thereby ensuring that it can maintain good operating condition even in harsh working environments.

[0042] In one embodiment, return to reference Figure 1The cutting device 4 of the sewage mixing treatment tank of this application consists of multiple cutters 41 arranged radially. Each cutter 41 has a serrated edge, which helps to enhance the chopping effect on large particles of sewage. The cutters 41 are installed inside the treatment tank, below the mixing device, and are securely connected to the drive shaft 2 by fasteners. Thus, the cutters 41 can perform effective cutting operations as the drive shaft 2 rotates.

[0043] Specifically, to prevent large particles of impurities from entangled on the drive shaft 2, the design of the cutter 41 takes into account the following aspects: First, the installation position of the cutter 41 is moderately positioned relative to the drive shaft 2, ensuring sufficient cutting space without being too far to affect transmission efficiency; second, the number and arrangement of the cutters 41 are carefully considered, with multiple cutters 41 arranged radially to ensure that large particles in the sewage are acted upon by forces from multiple directions, thus achieving a more uniform cutting effect. Through these designs, the entanglement of impurities on the drive shaft 2 is effectively reduced, improving the stability and efficiency of the entire system.

[0044] For example, in practical applications, cutters 41 with serrated edges can be manufactured through precise machining, and then evenly fixed to the drive shaft 2 using high-strength fasteners. The selection and installation method of the fasteners must ensure that the cutters 41 can work stably under high loads for a long time, preventing them from loosening or falling off due to vibration or wear. Specifically, a combination of bolts and clamping rings can be used to fix the cutters 41 to ensure their firmness and reliability.

[0045] In one embodiment, a protective cover 5 for a sewage mixing tank for sewage treatment according to this application includes a cylindrical structure with its upper end fixed to the inner wall of the tank body 1 and its lower end fitted onto a drive shaft 2. The inner diameter of the cylindrical structure is 10% to 20% larger than the diameter of the drive shaft 2, ensuring sufficient space between the protective cover 5 and the drive shaft 2. This design not only prevents large particles of impurities from directly contacting the drive shaft 2, but also effectively reduces the risk of damage or jamming of the drive shaft 2 due to entanglement. The upper end of the protective cover 5 is fixed to the inner wall of the tank body 1 by bolts or other fixing devices to ensure its stability. The lower end is tightly fitted onto the drive shaft 2, while leaving sufficient space to ensure that it does not affect the normal operation of the drive shaft 2.

[0046] For example, the protective cover 5 can be made of corrosion-resistant and high-strength stainless steel or plastic. Specifically, the cylindrical structure of the protective cover 5 can be fixed to a predetermined position on the inner wall of the pool body 1 by welding or mechanical connection. To ensure that the lower end can be smoothly fitted onto the drive shaft 2 and maintain an appropriate distance, an adjusting ring can be fitted over the drive shaft 2. The position of the adjusting ring can be precisely controlled by adjusting screws, thereby ensuring that the distance between the cylindrical structure and the drive shaft 2 meets the design requirements. This not only ensures the effective protective function of the protective cover 5, but also facilitates the maintenance and cleaning of the equipment.

[0047] In one embodiment, such as Figure 3 As shown, the protective cover 5 of a sewage mixing tank for sewage treatment according to this application includes multiple longitudinally arranged reinforcing ribs 51. The two ends of these reinforcing ribs 51 are respectively fixed to the upper and lower ends of the protective cover 5, forming multiple evenly distributed support structures, thereby enhancing the overall rigidity and stability of the protective cover 5. This design effectively prevents the protective cover 5 from deforming due to various external forces during long-term use. Through this structure, the protective cover 5 can ensure long-term effective anti-winding function, avoiding maintenance problems and performance degradation caused by deformation of the protective cover 5.

[0048] For example, the positions of the reinforcing ribs 51 can be pre-set during the manufacturing process of the protective cover 5, and the upper and lower ends of the reinforcing ribs 51 can be fixed to the upper and lower ends of the protective cover 5 by welding or other connection methods. These reinforcing ribs 51 can be made of high-strength materials to ensure that they can withstand various stresses during long-term use. In addition, the number and spacing of the reinforcing ribs 51 can be adjusted according to actual needs to achieve the best reinforcement effect. Specifically, the optimal number and layout of the reinforcing ribs 51 can be determined through finite element analysis during the design phase to ensure that the stiffness and stability of the protective cover 5 in all directions are optimal.

[0049] In one embodiment, the manure mixing tank for manure treatment according to this application has 3 to 5 reinforcing ribs 51, evenly distributed around the circumference of the protective cover 5. This design aims to optimize the stability and protective effect of the protective cover 5, preventing it from deforming or being damaged by external pressure or impact during operation. The presence of the reinforcing ribs 51 not only strengthens the overall structure of the protective cover 5 but also increases its impact resistance, making it more reliable in harsh working environments.

[0050] The specific number of reinforcing ribs 51 can be adjusted according to actual application needs and design requirements. For example, in high-pressure environments or applications requiring higher stability, a larger number of reinforcing ribs 51 can be selected, while under normal operating conditions, a smaller number of reinforcing ribs 51 is sufficient. Each reinforcing rib 51 is evenly arranged along the circumference of the protective cover 5, ensuring balanced support force in all directions, thereby improving the overall stability of the device. Specifically, one end of the reinforcing rib 51 is fixed to the inner wall of the treatment tank, and the other end is fixed to the outer surface of the protective cover 5. This connection method allows the reinforcing rib 51 to effectively distribute the load when under stress, preventing failure caused by local stress concentration.

[0051] In one embodiment, a cutting device 4 of a sewage mixing tank for sewage treatment according to this application is located at the bottom of the tank. The cutting device 4 is used to cut and crush the sewage entering the tank, ensuring uniformity and efficiency in subsequent treatment processes. To improve the durability and service life of the equipment, a wear-resistant plate 42 is added to the bottom of the cutting device 4. The hardness of this wear-resistant plate 42 is higher than that of the cutting blade 41 in the cutting device 4, effectively resisting the impact of large particles on the bottom of the cutting device 4. This design not only protects the cutting device 4 from damage but also ensures stable operation over a long period.

[0052] In one embodiment, the wear-resistant plate 42 is mounted on the bottom surface of the cutting device 4 and is tightly bonded to the bottom surface of the cutting device 4. The wear-resistant plate 42 is made of a high-hardness material, specifically a high-strength wear-resistant alloy or ceramic material. The wear-resistant plate 42 is connected to the bottom of the cutting device 4 by bolts or other fixing devices to ensure its stability. In addition, the surface of the wear-resistant plate 42 is flat and smooth, which helps to reduce fecal residue and facilitates cleaning and maintenance.

[0053] For example, the wear-resistant plate 42 can be machined to match the size and shape of the bottom of the cutting device 4, and then accurately installed onto the bottom of the cutting device 4 using high-precision installation tools. To ensure there are no gaps between the wear-resistant plate 42 and the bottom of the cutting device 4, specialized adhesives or other fixing methods can be used to increase the reliability and sealing of the connection. This design not only improves the impact resistance of the cutting device 4 but also extends the overall service life of the equipment.

[0054] In another embodiment, such as Figure 4 As shown, the discharge valve 6 of this application includes a baffle 61 that can move up and down. The baffle 61 can be driven by a cylinder, for example, to quickly open or close when discharging treated sewage, so as to prevent large particles of impurities from flowing back into the tank and getting tangled on the drive shaft 2 during the discharge process.

[0055] In actual operation, when this device is used, the sewage to be treated is first added to the tank 1 through the feed inlet. As the sewage is gradually poured into the tank 1, the drive shaft 2 is activated, driving the stirring blades 3 mounted on it to rotate, so that the sewage is evenly stirred, accelerating the mixing and decomposition of the substances. During this process, if the sewage contains large solid particles or fibrous materials, they will flow to the bottom of the tank 1 with the sewage. Here, the cutting device 4 fixed to the lower part of the drive shaft 2 begins to function. This device contains multiple cutting blades, which can effectively shear and crush larger impurities, turning them into smaller particles. The advantage of this is that it can prevent large particles from being thrown to the edge of the tank wall due to stirring, or even from getting tangled on the drive shaft 2, ensuring the safety and stability of the entire equipment operation. In addition, the protective cover 5 installed on the cutting device 4 and surrounding the drive shaft 2 also plays a key role. It can effectively prevent the crushed large particles and other residues from directly contacting the drive shaft 2, further reducing the risk of entanglement, while also reducing the load on the cutting device 4, improving working efficiency and extending service life. Finally, once treatment is complete or preset conditions are met, the treated wastewater can be smoothly discharged by opening the discharge valve 6 located at the bottom of tank 1, facilitating subsequent collection or transportation. Throughout operation, the coordinated work of these components not only improves the effectiveness and efficiency of wastewater treatment but also ensures the stable and reliable operation of the system.

[0056] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
