Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a coagulation and sedimentation device for chemical wastewater. Background Technology

[0002] Chemical wastewater contains a large amount of metal ions, so these metal ions need to be precipitated. In the prior art, a utility model patent with patent application number 202022061045.3 discloses a high-efficiency sedimentation device for wastewater treatment, which mainly consists of a sedimentation tank. In use, the wastewater to be treated is added to the sedimentation tank, followed by the addition of a precipitant. The metal ions in the wastewater then form solid precipitates under the action of the precipitant. The precipitated wastewater is then discharged from the sedimentation tank, and the sludge settled at the bottom of the tank is cleaned out. However, this method has the following problems: when cleaning the sludge in the sedimentation tank, some sludge also remains on the side walls of the tank, requiring manual cleaning by staff. Manual cleaning of the sludge on the side walls of the sedimentation tank is labor-intensive and inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a chemical wastewater coagulation and sedimentation equipment that can automatically scrape off sludge from the inner side wall of the sedimentation cylinder, reducing the labor intensity of workers, and is easy to use and highly practical.

[0004] This utility model discloses a coagulation and sedimentation device for chemical wastewater, comprising a base plate, a support frame, and a sedimentation cylinder. The sedimentation cylinder is fixedly mounted on the upper part of the base plate via the support frame. The sedimentation cylinder contains a chamber, and its upper end is open. A water pump is mounted on the base plate, and a delivery pipe is connected to the pump's input end, which is located within the chamber of the sedimentation cylinder. A drain pipe is mounted on the pump. A sludge discharge port communicating with the chamber is located at the lower part of the sedimentation cylinder chamber, and a sealing cap is installed outside the discharge port. The sealing cap is bolted to the sedimentation cylinder. The device also includes a lifting mechanism and a sludge scraping mechanism. The sludge scraping mechanism is mounted on the lifting mechanism, which is used to raise and lower the sludge scraping mechanism. Located above the sedimentation tank, the sludge scraping mechanism has the function of scraping sludge. When settling chemical wastewater, the wastewater is first added to the chamber of the sedimentation tank. Then, a flocculant is added to the chamber, causing the metal ions in the wastewater to precipitate to the lower part of the chamber under the action of the flocculant. Afterward, the water pump is turned on, allowing the settled wastewater to be discharged to the outside through the conveying pipe, water pump, and drain pipe for further treatment. When it is necessary to clean the sediment... When removing sludge from the sedimentation chamber, open the sludge scraping mechanism to scrape the sludge off the inner wall of the sedimentation tank. Simultaneously, open the lifting mechanism to adjust the height of the scraping mechanism, ensuring even scraping of the sludge off the inner wall of the sedimentation tank. The sludge adhering to the inner wall of the sedimentation tank is scraped down to the lower part of the sedimentation chamber. Then, open the sealing cover at the bottom of the sedimentation chamber to discharge the sludge from the lower part of the sedimentation chamber through the drain port. This system can automatically scrape the sludge off the inner wall of the sedimentation tank, reducing the labor intensity of workers, and is convenient and highly practical.

[0005] Preferably, the sludge scraping mechanism includes a fixed frame, a motor, a rotating shaft, an electric push rod, a scraper, a fixed plate, and a sliding plate. The fixed frame is mounted on a lifting mechanism for raising and lowering the fixed frame. The motor is fixedly mounted on the fixed frame, and the rotating shaft is rotatably mounted on the fixed frame. The upper end of the rotating shaft is connected to the output end of the motor. The fixed end of the electric push rod is fixedly mounted on the rotating shaft. The scraper is mounted on the movable part of the electric push rod. The fixed plate is fixedly mounted on the rotating shaft, and the sliding plate is slidably mounted on the fixed plate. The scraper is fixedly mounted on the sliding plate. When scraping the sludge on the inner wall of the sedimentation cylinder chamber, firstly... The lifting mechanism lowers the fixed frame, rotating shaft, and electric push rod, causing the scraper to descend into the sedimentation tank chamber. Then, the electric push rod is activated, moving the scraper until it contacts the inner wall of the sedimentation tank. The motor is then turned on, causing the rotating shaft to rotate, which in turn causes the electric push rod to rotate the scraper. During rotation, the scraper scrapes off the sludge from the inner wall of the sedimentation tank chamber. The lifting mechanism adjusts the height of the fixed frame and rotating shaft, which in turn adjusts the height of the scraper, ensuring even scraping of the sludge from both the upper and lower parts of the inner wall of the sedimentation tank chamber. This facilitates the cleaning of the sludge from the inner wall of the sedimentation tank chamber.

[0006] Preferably, the lifting mechanism includes a hoisting frame, a hydraulic cylinder, and a lifting rod. The hydraulic cylinder is fixedly installed on the upper end of the hoisting frame, and the lifting rod is slidably installed on the hoisting frame. The upper end of the lifting rod is connected to the output end of the hydraulic cylinder, and the fixed frame is fixedly installed on the lower end of the lifting rod. The hoisting frame is fixedly hoisted onto a support in the workshop. When it is necessary to adjust the height of the fixed frame, the hydraulic cylinder is opened, and the hydraulic cylinder drives the lifting rod to adjust the height, thereby adjusting the height of the fixed frame. This facilitates the adjustment of the height of the fixed frame.

[0007] Preferably, the system also includes a circular annular pipe, multiple sets of nozzles, multiple sets of liquid inlet pipes, and a liquid supply mechanism. The circular annular pipe is fixedly installed in the upper part of the sedimentation tank chamber. The multiple sets of nozzles and liquid inlet pipes are all connected to the circular annular pipe and are evenly distributed around its circumference. Each set of nozzles and liquid inlet pipes is equipped with a valve. The output ends of the multiple sets of nozzles all point towards the inner wall of the sedimentation tank, while the output ends of the multiple sets of liquid inlet pipes all point downwards. The output end of the liquid supply mechanism is connected to the circular annular pipe, and the liquid supply mechanism has a liquid supply function. When treating the wastewater in the sedimentation tank chamber, the valves on the multiple sets of nozzles are closed. Open the valves on multiple sets of liquid addition pipes, then open the liquid supply mechanism to add the precipitant into the annular pipe. The precipitant is then evenly sprayed into the wastewater within the sedimentation tank chamber through the multiple sets of liquid addition pipes on the annular pipe, causing uniform sedimentation. When scraping sludge from the inner wall of the sedimentation tank chamber, open the valves on multiple sets of nozzles and close the valves on the multiple sets of liquid addition pipes. Clean water is then delivered into the annular pipe through the liquid supply mechanism. The clean water is then sprayed onto the inner wall of the sedimentation tank through the multiple sets of nozzles on the annular pipe, washing away the sludge adhering to the inner wall and improving the cleaning effect.

[0008] Preferably, the liquid supply mechanism includes a delivery pump, a delivery pipe, an inlet pipe, pipe A, pipe B, a precipitant storage tank, and a clean water storage tank. The output end of the delivery pump is connected to the annular pipe via the delivery pipe, and the input end of the delivery pump is equipped with an inlet pipe. The output ends of pipes A and B are both connected to the inlet pipe. Valves are installed on both pipes A and B. Pipe A is connected to the precipitant storage tank, and pipe B is connected to the clean water storage tank. When precipitant is added to the sedimentation chamber, the valve on pipe B is closed, and the valve on pipe A is opened, allowing the precipitant in the precipitant storage tank to enter the annular pipe sequentially via pipe A, the inlet pipe, the delivery pump, and the delivery pipe. When it is necessary to clean the sludge on the inner wall of the sedimentation tank, the valve on pipe A is closed, and the valve on pipe B is opened, allowing the clean water in the clean water storage tank to enter the annular pipe sequentially via pipe B, the inlet pipe, the delivery pump, and the delivery pipe. This facilitates the delivery of liquid to the annular pipe.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 6The chemical wastewater coagulation and sedimentation equipment of this utility model includes a base plate 1, a support frame 2, a sedimentation cylinder 3, a lifting mechanism, and a sludge scraping mechanism. The sedimentation cylinder 3 is fixedly installed on the upper end of the base plate 1 via the support frame 2. A chamber is provided inside the sedimentation cylinder 3, and the upper end of the sedimentation cylinder 3 is open. A water pump is installed on the base plate 1, and a delivery pipe is installed at the input end of the water pump. The input end of the delivery pipe is located inside the chamber of the sedimentation cylinder 3. A drain pipe is installed on the water pump. A drain outlet communicating with the chamber is provided at the lower part of the chamber of the sedimentation cylinder 3, and a sealing cover is installed outside the drain outlet. The sealing cover is installed on the sedimentation cylinder 3 by bolts. The sludge scraping mechanism is installed on the lifting mechanism, which is used to raise and lower the sludge scraping mechanism. The sludge scraping mechanism is located above the sedimentation cylinder 3 and has the function of scraping sludge. When sedimenting chemical wastewater, the chemical wastewater is first added to the chamber of the sedimentation cylinder 3, and then... A precipitant is added, causing metal ions in the wastewater to precipitate to the lower part of the sedimentation tank 3 chamber. Then, the water pump is turned on, allowing the precipitated wastewater to be discharged to the outside via a conveying pipe, pump, and drain pipe for further treatment. When sludge needs to be cleaned from the sedimentation tank 3 chamber, the scraping mechanism is activated to remove sludge from the inner wall of the sedimentation tank 3. Simultaneously, the lifting mechanism is activated to adjust the height of the scraping mechanism, evenly scraping the sludge from the inner wall of the sedimentation tank 3 chamber, causing the sludge to fall to the lower part of the sedimentation tank 3 chamber. Finally, the sealing cover at the bottom of the sedimentation tank 3 chamber is opened, and the sludge is discharged through the drain port. This system automatically removes sludge from the inner wall of the sedimentation tank 3 chamber, reducing the labor intensity of workers, and is convenient and highly practical.

[0022] like Figure 1 and Figure 6The sludge scraping mechanism includes a fixed frame 4, a motor 5, a rotating shaft 6, an electric push rod 7, a scraper 8, a fixed plate 9, and a sliding plate 10. The fixed frame 4 is mounted on a lifting mechanism, which is used to lift the fixed frame 4. The motor 5 is fixedly mounted on the fixed frame 4. The rotating shaft 6 is rotatably mounted on the fixed frame 4, and the upper end of the rotating shaft 6 is connected to the output end of the motor 5. The fixed end of the electric push rod 7 is fixedly mounted on the rotating shaft 6. The scraper 8 is mounted on the moving part of the electric push rod 7. The fixed plate 9 is fixedly mounted on the rotating shaft 6. The sliding plate 10 is slidably mounted on the fixed plate 9. The scraper 8 is fixedly mounted on the sliding plate 10. When scraping the sludge on the inner wall of the sedimentation tank 3, firstly... The lifting mechanism lowers the fixed frame 4, rotating shaft 6, and electric push rod 7, causing the scraper 8 to descend into the chamber of the sedimentation tank 3. Then, the electric push rod 7 is activated, moving the scraper 8 to contact the inner wall of the sedimentation tank 3. The motor 5 is then activated, causing the rotating shaft 6 to rotate, which in turn causes the electric push rod 7 to rotate the scraper 8. During rotation, the scraper 8 scrapes off the sludge from the inner wall of the sedimentation tank 3. The lifting mechanism adjusts the height of the fixed frame 4 and rotating shaft 6, which in turn adjusts the height of the scraper 8, ensuring that the scraper 8 evenly scrapes the sludge from both the upper and lower parts of the inner wall of the sedimentation tank 3. This facilitates the cleaning of the sludge from the inner wall of the sedimentation tank 3.

The hydraulic cylinder 12 is fixedly installed on the upper end of the hoisting frame 11, and the lifting rod 13 is slidably installed on the hoisting frame 11. The upper end of the lifting rod 13 is connected to the output end of the hydraulic cylinder 12, and the fixed frame 4 is fixedly installed on the lower end of the lifting rod 13. The hoisting frame 11 is fixedly hoisted on the support in the workshop. When it is necessary to adjust the height of the fixed frame 4, the hydraulic cylinder 12 is opened, and the hydraulic cylinder 12 drives the lifting rod 13 to adjust the height, thereby adjusting the height of the fixed frame 4. This facilitates the adjustment of the height of the fixed frame 4.

The circular annular pipe 14 is fixedly installed on the upper part of the sedimentation tank 3 chamber. The multiple sets of nozzles 15 and multiple sets of liquid addition pipes 16 are all connected to the circular annular pipe 14 and are evenly distributed around the circumference of the circular annular pipe 14. Each set of nozzles 15 and multiple sets of liquid addition pipes 16 is equipped with a valve. The output ends of the multiple sets of nozzles 15 all point towards the inner wall of the sedimentation tank 3, and the output ends of the multiple sets of liquid addition pipes 16 all point downwards. The output end of the liquid supply mechanism is connected to the circular annular pipe 14, and the liquid supply mechanism has the function of supplying liquid. When the wastewater in the sedimentation tank 3 chamber is being treated for sedimentation, the multiple sets of nozzles 15 are closed. Open the valves on the multiple sets of liquid addition pipes 16, and then open the liquid supply mechanism to add the precipitant into the annular pipe 14. Then, the precipitant is evenly sprayed into the wastewater in the chamber of the sedimentation tank 3 through the multiple sets of liquid addition pipes 16 on the annular pipe 14, so that the wastewater is evenly precipitated. When scraping off the sludge on the inner wall of the chamber of the sedimentation tank 3, open the valves on the multiple sets of nozzles 15 and close the valves on the multiple sets of liquid addition pipes 16. The liquid supply mechanism delivers clean water into the annular pipe 14. Then, the clean water is sprayed onto the inner wall of the sedimentation tank 3 through the multiple sets of nozzles 15 on the annular pipe 14 to wash away the sludge attached to the inner wall of the sedimentation tank 3, thereby improving the cleaning effect.

[0025] like Figure 3 and Figure 5 The liquid supply mechanism includes a delivery pump 17, a delivery pipe 18, an inlet pipe 19, pipe A20, pipe B21, a precipitant storage tank 22, and a clean water storage tank 23.

The output ends of pipes A20 and B21 are both connected to the inlet pipe 19. Valves are provided on pipes A20 and B21. Pipe A20 is connected to the precipitant storage tank 22, and pipe B21 is connected to the clean water storage tank 23. When precipitant is added to the chamber of the sedimentation cylinder 3... When necessary, close the valve on pipe B21 and open the valve on pipe A20, allowing the precipitant in the precipitant storage tank 22 to enter the annular pipe 14 sequentially through pipe A20, inlet pipe 19, transfer pump 17, and delivery pipe 18. When it is necessary to clean the sludge on the inner wall of the sedimentation cylinder 3, close the valve on pipe A20 and open the valve on pipe B21, allowing the clean water in the clean water storage tank 23 to enter the annular pipe 14 sequentially through pipe B21, inlet pipe 19, transfer pump 17, and delivery pipe 18.
