Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling and reuse technology, and in particular to an energy-saving wastewater recycling and reuse device. Background Technology

[0002] With the rapid development of industrialization and urbanization, the problem of water shortage is becoming increasingly severe. Wastewater recycling and reuse has become an important way to alleviate water resource pressure. Traditional wastewater treatment technologies generally suffer from high energy consumption and low treatment efficiency, making it difficult to meet the energy-saving and environmental protection needs of modern industry. Especially in industries such as chemical, printing and dyeing, and food processing, wastewater contains a large amount of suspended solids and colloidal impurities. If the treatment is not thorough, it will not only increase the burden on subsequent treatment stages, but also lead to problems such as equipment blockage and waste of reagents. Therefore, developing a high-efficiency and energy-saving wastewater recycling and reuse equipment that achieves multi-stage filtration and convenient maintenance is of great significance for improving water resource utilization and reducing treatment costs.

[0003] Currently, most common wastewater treatment equipment adopts single-stage or multi-stage fixed filtration structures, such as screen filtration, activated carbon adsorption, or membrane separation technology. These devices typically remove impurities through physical interception or chemical adsorption. Some devices combine sedimentation tanks or centrifugal separation technology to improve treatment efficiency. In terms of mechanical structure, filter components are mostly installed by bolt fixing or welding, requiring disassembly of the entire structure for maintenance, which is cumbersome. In addition, existing equipment often lacks efficient sewage discharge design, and sediment tends to accumulate at the bottom of the equipment, affecting filtration efficiency. Although some equipment uses backwashing technology to clean the filter screen, there are still problems such as high energy consumption and incomplete cleaning, making it difficult to achieve long-term stable operation.

[0004] Traditional wastewater treatment equipment has significant shortcomings in the filtration stage, especially single-stage filtration structures, which are poor at intercepting tiny impurities, resulting in substandard effluent quality. Due to incomplete filtration, subsequent treatment stages require additional reagent dosage or extended treatment time, which not only increases energy consumption and operating costs but also easily causes secondary pollution. In addition, fixed filter screens are difficult to replace and have long maintenance cycles, further reducing the efficiency of the equipment. These problems seriously restrict the promotion of wastewater recycling technology, necessitating a new filtration structure to solve the problems of incomplete filtration and inconvenient maintenance. Therefore, an energy-saving wastewater recycling device is proposed to address the above issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving wastewater recycling and reuse equipment, including a shell, an inlet pipe fixedly connected to the top of the shell, a drain pipe fixedly connected to the outer wall of the shell, a connecting plate fixedly connected inside the shell, and a filter assembly disposed inside the connecting plate;

[0007] The filter assembly includes filter screen one and filter screen two. The outer walls of filter screen one and filter screen two are attached to the inside of the connecting plate.

[0023] 1.

This solves the problems of decreased processing efficiency, increased energy consumption, equipment corrosion and secondary pollution caused by sediment accumulation in traditional equipment, and improves the stability of the equipment.

[0036] The filter assembly includes filter screen 4 and filter screen 5. Filter screen 4 is used for preliminary filtration of larger particulate impurities in wastewater, while filter screen 5 is used for further filtration of fine suspended solids to improve water quality. The outer walls of filter screens 4 and 5 are fitted together with the interior of the connecting plate 6 to ensure the filter assembly is securely installed and to prevent leakage of unfiltered wastewater. A fixing plate 7 is fixedly connected inside filter screen 4, which supports the sliding structure of the locking block 8 and the limiting block 9. The locking block 8 is slidably connected inside filter screen 4, and the outer wall of the locking block 8 is slidably connected inside the connecting plate 6. The filter screen 4 is designed for quick locking, facilitating installation and disassembly. A limiting block 9 is slidably connected inside the filter screen 4 to restrict the movement range of the locking block 8, preventing it from disengaging from its working position. A spring 10 is installed inside the filter screen 4, with one end fixedly connected to the outer wall of the limiting block 9 and the other end fixedly connected to the outer wall of the fixing plate 7. The spring 10 provides elastic force to keep the locking block 8 in a stable engaged state. A drain assembly is installed inside the outer casing 1 to periodically clean impurities trapped by the filter assembly and maintain filtration efficiency.

[0037] Reference Figures 5-7 The sewage discharge assembly includes a connecting block 15 and a connecting cover 16. The connecting cover 16 is slidably connected inside the connecting block 15 to form a sealable sewage discharge channel, ensuring that wastewater does not leak during sewage discharge. One side of the connecting block 15 is fixedly connected to the outer wall of the outer shell 1, providing stable support for the sewage discharge assembly and maintaining structural integrity. A guide block 11 is fixedly connected inside the outer shell 1 to concentrate filtered impurities and guide them to the sewage discharge port, improving sewage discharge efficiency. A separation block 12 is fixedly connected inside the outer shell 1 to isolate the filtration zone and the sewage discharge zone, preventing impurities from flowing back and contaminating the filtered water. A push plate 14 is provided inside the outer shell 1 to push deposited impurities toward the sewage discharge port for thorough sewage discharge. A push rod 13 is fixedly connected to the outer wall of the outer shell 1, and the output end of the push rod 13 is fixedly connected to the outer wall of the push plate 14 to provide linear driving force for the push plate 14, ensuring stable and reliable sewage discharge. A hollow block 1 is fixedly connected inside the connecting cover 16. 7. As the mounting base for the sliding mechanism, a sliding rod 20 is slidably connected inside the hollow block 17. The outer wall of the sliding rod 20 is slidably connected inside the connecting cover 16 and inside the connecting block 15, forming the opening and closing mechanism of the connecting cover 16 to realize the opening and closing control of the sewage outlet. One end of the sliding rod 20 is fixedly connected to a limit plate 18, and the outer wall of the limit plate 18 is slidably connected inside the hollow block 17 to limit the travel range of the sliding rod 20. A pull plate 19 is fixedly connected to the outer wall of the limit plate 18, and the pull plate 19 is slidably connected to the outside of the hollow block 17 to provide a manual operation interface for easy manual control. A second spring 21 is provided on the outer wall of the sliding rod 20. One end of the second spring 21 is fixedly connected inside the hollow block 17, and the other end of the second spring 21 is fixedly connected to the outer wall of the limit plate 18 to provide automatic reset force for the sliding rod 20, ensuring that the connecting cover 16 remains sealed when not in operation.

[0038] Working principle: When filtering wastewater inside the outer casing 1, the wastewater is discharged into the outer casing 1 through the inlet pipe 2. At this time, the wastewater undergoes preliminary filtration of impurities through filter screen 4. The filtered wastewater then undergoes secondary filtration through filter screen 5, which filters out smaller impurities, forming a two-stage filtration process. By pressing the locking block 8, the locking block 8 moves the limiting block 9 into the fixing plate 7. At this time, the limiting block 9 compresses the spring 10, causing the locking block 8 to disengage from the connecting plate 6, thus achieving the effect of quickly disassembling filter screen 4. When cleaning the internal sediment, the sliding rod 20 and the connecting block 15 are separated by pulling the pull plate 19 and driving the limit plate 18. At this time, after the connecting cover 16 is removed, the filtered wastewater is discharged to the bottom of the outer shell 1 through the guide block 11. The separation block 12 separates the water and the water at the top is diverted to the other side of the separation block 12 by overflow. The drain pipe 3 discharges the overflowed water. The output end of the separation block 12 drives the push plate 14 to clean the sediment at the bottom out of the inner shell 1 through the connecting block 15, thereby achieving the effect of cleaning the sediment at the bottom of the outer shell 1.
