Description

Technical Field

[0001] This utility model relates to the technical field of wastewater recycling equipment for waste-to-energy plants, specifically to a device for recycling wastewater from waste-to-energy plants. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of population, waste disposal has become an increasingly serious problem. Waste-to-energy plants, as an effective way to dispose of waste, can not only convert waste into electricity, but also realize the resource utilization of wastewater through wastewater recycling devices, thereby reducing environmental pollution. However, traditional wastewater treatment systems in waste-to-energy plants have problems such as low treatment efficiency and substandard water quality, making it difficult to meet modern environmental protection requirements.

[0003] Traditional wastewater treatment systems typically employ simple filtration and sedimentation methods to remove suspended solids and particulate matter from wastewater. However, this method has limited effectiveness in removing pollutants such as dissolved organic matter and heavy metal ions from wastewater, making it difficult for the effluent quality to meet discharge standards or reuse requirements. In addition, traditional wastewater treatment systems also suffer from problems such as cumbersome treatment processes, large footprint, and high operating costs, which limit their widespread application in waste-to-energy plants.

[0004] In view of this, we will study and improve the existing structure and its shortcomings, and provide a device for recycling wastewater from waste-to-energy plants, in order to achieve a more practical purpose. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a device for recycling wastewater from waste-to-energy plants, which has the following beneficial effects:

[0016] 1. The designed filter assembly effectively intercepts large particulate impurities and suspended solids in wastewater using the internal filter screen. The fixed frame and baffle further enhance the filtration effect, preventing impurities from passing through with the water flow. This design not only improves filtration efficiency but also ensures the cleanliness of the effluent. Furthermore, the stirring assembly, driven by a motor, rotates three driven gears via a drive gear, which in turn drives the stirring blades to generate a strong stirring action within the mixing tank. This multi-stage transmission and stirring method allows the wastewater and flocculant to mix thoroughly, accelerating the flocculation reaction and thus improving the efficiency and quality of wastewater treatment.

[0017] 2. By adopting an integrated design, key treatment components such as the filtration tank, stirring components, anaerobic treatment tank, and purification tank are closely connected through output pipes to form a complete wastewater treatment system. This design not only simplifies the wastewater treatment process but also improves the continuity and automation of the treatment. Wastewater undergoes multiple stages in the system, including preliminary filtration, stirring and flocculation, anaerobic treatment, and purification. Each stage is seamlessly connected, avoiding wastewater retention and pollution during the treatment process. At the same time, the purifier at the top of the purification tank performs final treatment of the wastewater, ensuring that the effluent quality meets discharge standards or reuse requirements. This integrated design and connectivity optimize the wastewater treatment process, improving treatment efficiency and resource utilization. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4A wastewater recycling device for a waste-to-energy plant includes a housing 1. An inlet pipe 2 is connected through one side of the housing 1, and a valve 3 is fixedly installed on the upper wall of the inlet pipe 2. An outlet pipe 14 is connected through the other side of the housing 1. A filter tank 4 is fixedly connected to the inner wall of the housing 1. A filter assembly 5 is provided inside the filter tank 4. A fixing plate 8 is fixedly connected to the inner wall of the housing 1. A stirring assembly 7 is provided below the fixing plate 8. A flocculant tank 10 is fixedly connected to the upper surface of the fixing plate 8. A motor 9 is also installed on the upper surface of the fixing plate 8. An anaerobic treatment tank 11 is also fixedly connected to the inner wall of the housing 1. A purification tank 12 is fixedly installed on one side of the anaerobic treatment tank 11.

[0025] Furthermore, the filter assembly 5 includes a filter plate 501 fixedly connected to the inner wall of the filter tank 4. A filter screen 502 is fixedly provided inside the filter plate 501. Connecting rods 503 are fixedly connected to the four corners of the filter plate 501. A fixed frame plate 504 is fixedly connected to the other end of the connecting rods 503 away from the filter plate 501. A baffle 505 is fixedly connected to the inner wall of the fixed frame plate 504. There are several baffles 505, which are distributed at equal intervals on the inner wall of the fixed frame plate 504. The filter screen 502 not only improves the filtration efficiency but also ensures the stability of the filtration effect. At the same time, the four corners of the filter plate 501 are fixedly connected to the fixed frame plate through the connecting rods. This structure not only enhances the overall stability of the filter assembly but also facilitates subsequent maintenance and replacement.

[0026] Furthermore, the stirring assembly 7 includes a first rotating shaft 701 coaxially connected to the motor 9. The first rotating shaft 701 passes through the fixed plate 8 and is rotatably connected to the motor 9. A drive gear 702 is rotatably connected to the outer surface of the first rotating shaft 701. A positioning plate 703 is also rotatably connected to the outer surface of the first rotating shaft 701. Three driven gears 704 are meshed with the outer surface of the drive gear 702. Each driven gear 704 passes through and is rotatably connected to the upper surface of the positioning plate 703. Through the first rotating shaft 701 coaxially connected to the motor 9, efficient power transmission is achieved. The first rotating shaft 701 not only passes through the fixed plate 8 and is stably connected to the motor 9, but also cleverly has the drive gear 702 set on its outer surface. This design allows the rotational power of the motor 9 to be converted into stirring power. The meshing connection between the drive gear 702 and the three driven gears 704 constitutes a multi-stage transmission system. This design not only improves the uniformity and efficiency of stirring, but also achieves precise control of the stirring intensity.

[0027] Furthermore, a second rotating shaft 705 is rotatably connected to the middle of each driven gear 704. A stirring blade 706 is fixedly connected to the outer surface of the second rotating shaft 705. A stirring tank 707 is fixedly provided outside the stirring blade 706. The stirring blade 706 is located inside the stirring tank 707. The stirring tank 707 is fixedly connected to the inner wall of the housing 1. The second rotating shaft 705 rotatably connected to the middle of each driven gear 704 not only serves as a transmission medium to transmit the rotational power of the driving gear 702 to the stirring blade 706, but also ensures that the stirring blade 706 can rotate at a stable speed and angle.

[0028] Furthermore, an output pipe 6 is fixedly connected to the outer wall of the filter tank 4. The other end of the output pipe 6 away from the filter tank 4 is connected to the stirring tank 707. There are three output pipes 6, and each output pipe 6 is the same. The filter tank 4, stirring assembly 7, anaerobic treatment box 11, and purification tank 12 are all connected through the output pipes 6, which enhances the connectivity between the various treatment stages.

[0029] Furthermore, a purifier 13 is fixedly connected to the top of the purification tank 12, and the water outlet pipe 14 extends through the box body 1 into the interior of the purification tank 12.

[0030] Working principle: Wastewater enters the tank 1 through the inlet pipe 2. The valve 3 on the inlet pipe 2 controls the inflow speed and flow rate of the wastewater, ensuring that the wastewater enters the treatment system stably and orderly. After entering the filter tank 4, the wastewater first passes through the filter assembly 5, which consists of a filter plate 501 and an internal filter screen 502. The filter screen 502 is used to remove large particulate impurities and suspended solids in the wastewater. The fixed frame plate 504 and the baffle 505 help to further intercept and fix impurities, preventing them from entering the subsequent treatment stages with the water flow. The wastewater that has undergone preliminary filtration flows into the mixing tank 707 through the outlet pipe 6. At this time, the motor 9 starts, driving the first rotating shaft 701 to rotate. The driving gear 702 on the first rotating shaft 701 meshes with the three driven gears 704, thereby driving the second rotating shaft. 705 and stirring blade 706 rotate, and the rotation of stirring blade 706 generates a stirring effect, so that the wastewater is fully mixed with the flocculant added from flocculant tank 10. The role of flocculant is to agglomerate the small particles in the wastewater into larger flocs, which facilitates subsequent treatment. After stirring and flocculation treatment, the wastewater flows into anaerobic treatment tank 11 through outlet pipe 6. In anaerobic treatment tank 11, the wastewater undergoes biological treatment under anaerobic conditions. Anaerobic microorganisms decompose organic matter into gases such as methane and carbon dioxide, thereby reducing the organic matter content in the wastewater. The anaerobic wastewater enters purification tank 12. The purifier 13 at the top of purification tank 12 further treats the wastewater to remove residual pollutants and odors. Finally, the treated wastewater is discharged from tank 1 through outlet pipe 14, meeting the reuse or discharge standards.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
