[0002] Wastewater refers to water generated during industrial production, daily life, and other processes, whose quality and function have been polluted or damaged, and which no longer meet specific usage requirements. It may contain various pollutants such as suspended solids, organic matter, heavy metals, and microorganisms. If discharged directly without treatment, it will cause serious harm to the water body, soil, and other ecological environments, as well as human health. Wastewater sedimentation is a commonly used physical method in wastewater treatment. Its principle is to utilize the density difference between solid impurities and water in the water, and to use gravity to make the solid impurities sink, thereby achieving solid-liquid separation.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A wastewater sedimentation and recovery device includes a sedimentation tank 1, which is equipped with an inlet pipe and an overflow pipe. A filter plate 2 for separating large solids is fixedly installed inside the sedimentation tank 1. A collection hopper 13 is integrally formed at the bottom of the sedimentation tank 1 and is located below the filter plate 2. A sludge pump 14 is fixedly installed on one side of the bottom of the collection hopper 13, and the extraction end of the sludge pump 14 is connected to the bottom of the collection hopper 13.

[0027] The main function of the sedimentation tank 1 is to provide sedimentation space for wastewater, allowing solid impurities in the wastewater to settle naturally under gravity, thus achieving preliminary solid-liquid separation. The filter plate 2 is installed inside the sedimentation tank 1, acting as a barrier to accurately intercept larger solid impurities, preventing them from mixing with fine sediments and avoiding problems such as pipe blockage and equipment damage in subsequent treatment processes. The collection hopper 13 is located below the filter plate 2 and has a funnel-shaped structure. It acts as a collection container, gathering the fine sediments that have settled to the bottom of the sedimentation tank 1 after being separated by the filter plate 2, making it convenient for the sludge pump 14 to extract and process them. The three work together to ensure the efficient and stable operation of the wastewater sedimentation and recycling process.

[0028] It also includes a pushing assembly for collecting large solid impurities. The pushing assembly includes a pushing plate 3, with multiple sets of pushing rods 4 evenly spaced at the bottom of the pushing plate 3. The pushing rods 4 are installed at the bottom of the pushing plate 3 by screws, and the bottom of the pushing rods 4 abuts against the top surface of the filter plate 2. The top of the pushing plate 3 is fixedly connected to a movable plate 6 by two sets of connecting rods 5. A movable seat 7 is fixedly installed in the middle of the top of the movable plate 6. The movable seat 7 is installed on the surface of the lead screw 8. The two ends of the lead screw 8 are respectively rotatably installed on the inner side of two sets of mounting plates 15. The mounting plates 15 are fixedly installed on the top of the sedimentation tank 1. One end of the lead screw 8 is connected to the output end of the motor 16. The motor 16 is fixedly installed on the outer side of the mounting plate 15. A control device is provided on one side of the motor 16. The control box 17 of the machine 16 is fixedly connected to the mounting plate 15. Two sets of guide rods 18 are provided at both ends of the lead screw 8. The two ends of the guide rods 18 are fixedly connected to the two sets of mounting plates 15 respectively. A slide seat 19 is slidably installed on the surface of the guide rod 18. The slide seat 19 is fixedly connected to both ends of the moving plate 6. The control box 17 integrates a main control and logic control unit to realize timing function and signal processing. It also has motor 16 drive and power control components to realize motor 16 start, stop, speed adjustment and direction control, as well as power conversion module and energy storage components to ensure stable power supply. Sensors and feedback components realize closed-loop control. In addition, it also has human-machine interaction components such as buttons and display screens and communication interfaces to realize parameter setting and remote control.

[0029] By setting up a pushing component, the function is to transfer large solid impurities intercepted by the filter plate 2 to the lifting component in a timely manner. Its working principle is that the motor 16 drives the lead screw 8 to rotate, which drives the pushing plate 3, which is fixedly connected to the moving seat 7, to move linearly along the guide rod 18. The pushing rods 4, which are equidistantly arranged at the bottom, are in close contact with the top surface of the filter plate 2. During the movement, the large impurities are pushed towards the discharge port 12. The whole process can be carried out without stopping the sedimentation operation, avoiding the tediousness of manual cleaning and ensuring that the filter plate 2 continues to play its interception role.

[0030] It also includes a lifting assembly for discharging large solid impurities. The lifting assembly includes a bucket elevator 9. The feed inlet 10 on one side of the bucket elevator 9 is connected to the discharge outlet 12 on one side of the bottom of the sedimentation tank 1 through a ramp channel 11. The discharge outlet 12 is located on one side of the filter plate 2. The bottom of the discharge outlet 12 is at the same level as the top surface of the filter plate 2. A slag outlet 20 is provided on the other side of the bucket elevator 9. The position of the slag outlet 20 is higher than the liquid level in the sedimentation tank 1. A drain hole is provided at the bottom of the lifting unit 21 of the bucket elevator 9.

[0031] By setting up the lifting component, its function is to lift large solid impurities pushed by the pushing component from the bottom of the sedimentation tank 1 to a high place for discharge. The impurities enter the feed inlet 10 through the inclined channel 11 and are received and lifted by the lifting unit 21 with drainage holes. During the lifting process, the drainage holes can reduce the amount of wastewater carried. Finally, the impurities are discharged through the slag outlet 20, realizing solid-liquid separation and efficient removal of impurities, preventing large impurities from accumulating in the sedimentation tank 1 and affecting the treatment effect.

[0032] In practical use, the device is moved to a designated location, and wastewater flows into sedimentation tank 1 through the inlet pipe. In sedimentation tank 1, solid impurities settle due to gravity. Large solid impurities are intercepted by filter plate 2, while fine sediments fall into collection hopper 13 below. When a certain amount of impurities accumulate on filter plate 2, control box 17 starts motor 16. Motor 16 drives screw 8 to rotate, pushing component moving seat 7 along screw 8. Push plate 3 and push rod 4 push large solid impurities towards discharge port 12. The impurities enter the feed port 10 of bucket elevator 9 through inclined channel 11. Bucket elevator 9 of the lifting component receives the impurities and lifts them upward through lifting unit 21 with drainage holes. Water flows back from the drainage holes, and finally the impurities are discharged from slag outlet 20. Fine sediments in collection hopper 13 are pumped out by mud pump 14, completing the entire wastewater sedimentation and recycling process, which is efficient and stable.

[0033] 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.
