Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-speed shearing machine for wastewater treatment. Background Technology

[0002] Wastewater treatment technology is a system of technologies that uses physical, chemical, and biological methods to treat industrial wastewater and domestic sewage, removing pollutants (such as organic matter, suspended solids, and heavy metals) to meet discharge standards or reuse requirements. It encompasses pretreatment and advanced treatment stages, reducing wastewater pollution, protecting water resources, and enabling water recycling. It has wide applications in environmental protection, municipal works, and industry.

[0003] To address the pretreatment or specific separation needs in wastewater treatment technology, a high-speed shearing machine for wastewater treatment has been developed, serving as a key component in wastewater treatment equipment. This equipment uses high-speed rotating shearing components to powerfully shear and break down lumpy pollutants and wastewater flocs in the wastewater. This not only prevents clogging of subsequent treatment equipment but also increases the contact area between pollutants and treatment agents, creating favorable conditions for subsequent processes such as magnetic seed recovery and wastewater dewatering, effectively improving wastewater treatment efficiency and resource recovery rates.

[0004] However, in existing technologies, some high-speed shearing machines for wastewater treatment experience wastewater accumulation at the bottom of the device during operation due to structural gaps between the shearing mechanism and the base, or incomplete shearing coverage. This accumulation not only leads to incomplete wastewater treatment and material waste, but also gradually blocks the material flow channels inside the base.

[0005] Therefore, a high-speed shearing machine for sewage treatment is proposed to address the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-speed shearing machine for wastewater treatment, aiming to improve the situation where, in some existing high-speed shearing machines for wastewater treatment, some of the sheared wastewater tends to fall and accumulate at the bottom of the device during operation. This not only wastes wastewater materials but also gradually clogs the material flow channels.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A high-speed shearing machine for sewage treatment includes a base, an oil injection pipe fixedly connected to the top of the base, a transmission assembly fixedly connected to the top of the base, two cutter rollers fixedly connected to the bottom of the transmission assembly, multiple blades fixedly connected to the outside of the cutter rollers, two conical cavities opened inside the base, a rotating rod fixedly connected to the inner wall of the cutter rollers, threaded blades fixedly connected to the outside of the rotating rods, an outer cylinder fixedly connected to the inner wall of the conical cavities, and multiple through grooves opened on the outside of the cutter rollers. As a further description of the above technical solution: A feed pipe is fixedly connected to the left side of the base, and a discharge pipe is fixedly connected to the right side of the base; As a further description of the above technical solution: The transmission assembly includes a motor fixed to the top of the base, a drive shaft fixedly connected to the drive end of the motor, a drive gear fixedly connected to the bottom of the drive shaft, a driven gear rotatably connected to the inner wall of the base and meshing with the drive gear, and the tops of the two cutter rollers fixed to the bottoms of the drive gear and the driven gear, respectively. As a further description of the above technical solution: A rotating column is fixedly connected to the top of the driven gear, and the outside of the rotating column is rotatably connected to the inner wall of the base. As a further description of the above technical solution: The inner wall of the through groove is fixedly connected with multiple ramps, and the inner side of the ramps is rotatably connected to the outside of the outer cylinder. As a further description of the above technical solution: The base has an oil groove inside, which is connected to an oil injection pipe, and the other end of the oil groove leads to the top of the drive gear. As a further description of the above technical solution: The external rotatable connection of the cutter rollers is to the internal connection of the base, and the multiple blades on the two cutter rollers are arranged in an alternating and staggered manner. As a further description of the above technical solution: The threaded blade is externally rotatably connected to the inner wall of the outer cylinder, and the outer cylinder is externally rotatably connected to the inner wall of the cutter roller.

[0008] This utility model has the following beneficial effects: In this invention, the wastewater and impurities falling during the shearing process can be effectively collected by the collection effect of the conical cavity. Then, through the cooperation structure of the rotating rod, the threaded blade and the outer cylinder, the collected wastewater and impurities are transported back to the shearing area by the threaded conveying and centrifugal force. Subsequently, two cutter rollers are used to transport them out, which reduces wastewater waste and also reduces the risk of internal blockage of the equipment. Attached Figure Description

[0011] 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.

[0012] Reference Figures 1 to 6 This utility model provides an embodiment of a high-speed sewage treatment shearing machine, including a base 1. The base 1 is the installation foundation of the entire equipment, providing stable support for each component, and its internal space provides a accommodating area for sewage shearing, recycling, and conveying. A feed pipe 2 is fixedly connected to the left side of the base 1, which is used to introduce the sewage to be treated into the interior of the base 1, providing a raw material input channel for subsequent shearing. A discharge pipe 3 is fixedly connected to the right side of the base 1, which is used to discharge the sewage after shearing, realizing the discharge of treated sewage. An oil injection pipe 4 is fixedly connected to the top of the base 1, which is used to inject lubricating medium into the oil tank inside the base 1, providing a medium input path for the lubrication of the transmission components.

[0013] A transmission assembly is also fixedly connected to the top of the base 1. The transmission assembly is used to transmit power to the cutter roller 10 and drive the cutter roller 10 to rotate to achieve the shearing action. The transmission assembly includes a motor 5 fixed to the top of the base 1. The motor 5 is the power source of the equipment and can output rotational power to provide power support for the entire transmission process and the rotation of the cutter roller 10. A drive shaft 6 is fixedly connected to the drive end of the motor 5. The drive shaft 6 is used to transmit the power output by the motor 5 to the drive gear 7 to realize the transfer of power. A drive gear 7 is fixedly connected to the bottom of the drive shaft 6. The drive gear 7 receives the power transmitted by the drive shaft 6 and rotates. On the other hand, it transmits power to the driven gear 8 by meshing with the driven gear 8. At the same time, the size difference between the drive gear 7 and the driven gear 8 can create a speed difference, creating conditions for efficient shearing of sewage.

[0014] An oil groove is provided inside the base 1. The oil groove is used to transport the lubricating medium injected from the oil injection pipe 4 and to precisely guide the lubricating medium to the top of the drive gear 7, so as to provide lubrication for the meshing part of the drive gear 7, reduce gear wear, and ensure smooth transmission. The oil groove is connected to the oil injection pipe 4, and the other end of the oil groove leads to the top of the drive gear 7. A driven gear 8 that meshes with the drive gear 7 is rotatably connected to the inner wall of the base 1. The driven gear 8 receives power and rotates by meshing with the drive gear 7, thereby driving the corresponding cutter roller 10 to rotate. At the same time, it forms a speed difference with the drive gear 7, which improves the cutting efficiency of the blade 11. A rotating column 9 is fixedly connected to the top of the driven gear 8. The rotating column 9 is used to support the driven gear 8, limit the radial displacement of the driven gear 8, and ensure the stability of the driven gear 8 during rotation.

[0015] The rotating column 9 is externally rotatably connected to the inner wall of the base 1. Two cutter rollers 10 are fixedly connected to the bottom of the transmission assembly. The cutter rollers 10 are used to mount the blades 11 and rotate under the drive of the transmission assembly. Through their own rotation, they drive the blades 11 to move synchronously, realizing the shearing action on the sewage. The tops of the two cutter rollers 10 are respectively fixed to the bottom of the drive gear 7 and the driven gear 8. Multiple blades 11 are fixedly connected to the outside of the cutter rollers 10. The blades 11 rotate under the drive of the cutter rollers 10. The multiple blades 11 are arranged alternately and staggeredly. Through relative motion, they generate shearing force to crush the impurities in the sewage, realizing the initial step of sewage purification. The cutter rollers 10 are externally rotatably connected to the inside of the base 1, and the multiple blades 11 on the two cutter rollers 10 are arranged alternately and staggeredly. This alternating and staggered arrangement can expand the shearing range, improve the comprehensiveness and efficiency of shearing, and ensure that the impurities in the sewage are fully crushed.

[0016] The base 1 has two conical cavities 12 inside. The conical cavities 12 use their own conical structure to collect the sewage that falls to the bottom of the base 1 during the shearing process, like a funnel, to prevent the sewage from accumulating at the bottom of the base 1 and to provide conditions for subsequent sewage recycling. The inner wall of the cutter roller 10 is fixedly connected to a rotating rod 13. The rotating rod 13 rotates synchronously with the cutter roller 10 and can drive the external threaded blades 14 to rotate together, providing power for the threaded blades 14 to transport sewage. The external part of the rotating rod 13 is fixedly connected to the threaded blades 14. The threaded blades 14 rotate under the drive of the rotating rod 13, which can stably and efficiently roll up the sewage collected in the conical cavities 12 and flow into the bottom notch of the outer cylinder 15 and transport it upward, realizing the recycling and transfer of sewage.

[0017] An outer cylinder 15 is fixedly connected to the inner wall of the conical cavity 12. The outer cylinder 15 provides a channel for receiving and guiding sewage transported by the threaded blades 14. Its bottom notch facilitates sewage inflow, and its top notch facilitates sewage being thrown out under centrifugal force. At the same time, its inner wall cooperates with the threaded blades 14 to ensure the stability of sewage transport. The outer side of the threaded blades 14 is rotatably connected to the inner wall of the outer cylinder 15, and the outer side of the outer cylinder 15 is rotatably connected to the inner wall of the cutter roller 10. The outer side of the cutter roller 10 has multiple through grooves 16, which are used for sewage thrown out from the top notch of the outer cylinder 15 to pass through, so that the recovered sewage can be thrown out from inside the cutter roller 10 to the outside of the cutter roller 10 and re-enter the shearing area. Multiple ramps 17 are fixedly connected to the inner wall of the through grooves 16. The ramps 17 are used to guide the sewage thrown out from the through grooves 16 to ensure that the sewage can be discharged smoothly from the through grooves 16 and avoid sewage accumulation in the through grooves 16. The inner side of the ramps 17 is rotatably connected to the outside of the outer cylinder 15.

[0018] Working principle: First, wastewater enters the base 1 through the feed pipe 2. The motor 5 starts, driving the drive gear 7 to rotate via the drive shaft 6. The drive gear 7 meshes with the driven gear 8, causing the driven gear 8 to rotate synchronously. The driven gear 8 is smaller than the drive gear 7, ensuring stable rotation while creating a speed difference to prepare for efficient wastewater shearing. The drive gear 7 and driven gear 8 respectively drive two cutter rollers 10 to rotate. The blades 11 arranged in a staggered pattern on the outside of the cutter rollers 10 work together to shear and crush the wastewater.

[0019] During the process of blade 11 cutting sewage, some sewage will fall to the bottom of base 1. At this time, the conical cavity 12 opened inside base 1 comes into play. It can use its own conical structure to collect the fallen sewage like a funnel.

[0020] Next, as the cutter roller 10 rotates, it drives the rotating rod 13 fixed to its inner wall and the threaded blades 14 on the outside of the rotating rod 13 to rotate synchronously. Wastewater flows through the notch at the bottom of the outer cylinder 15 onto the threaded blades 14. At this time, the threaded blades 14 can stably and efficiently roll up the wastewater. As the threaded blades 14 rotate, the wastewater is conveyed upwards. When it reaches the top of the inner wall of the outer cylinder 15, under the action of centrifugal force, the wastewater is thrown out through the notch in the outer cylinder 15.

[0021] Subsequently, the wastewater is thrown outward from the through-slot 16 opened on the outside of the cutter roller 10. Multiple ramps 17 fixed on the inner wall of the through-slot 16 guide the wastewater to flow out more smoothly from the through-slot 16, preventing the wastewater from accumulating in the through-slot 16. Since the through-slot 16 is opened in the center of the feed pipe 2 and the discharge pipe 3, the thrown wastewater is driven by the rotating cutter roller 10 and blades 11 to flow towards the discharge pipe 3, and is finally output from the discharge pipe 3.

[0022] In addition, the oil groove inside the base 1 is connected to the oil injection pipe 4, and the other end of the oil groove leads to the top of the drive gear 7. Lubricating medium can be injected into the oil groove through the oil injection pipe 4 to lubricate the drive gear 7, ensure the smooth operation of the transmission components, reduce wear during gear meshing, and extend the service life of the equipment.

[0023] The aforementioned structural synergy not only enables efficient shearing of wastewater but also allows for the recycling and reprocessing of spilled wastewater, reducing wastewater waste and lowering the risk of internal equipment blockage.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
