Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment evaporation and concentration device. Background Technology

[0002] In the field of wastewater treatment, evaporation and concentration technology is widely used as an important treatment method in the treatment of various industrial wastewater and domestic sewage. However, when wastewater enters the evaporation and concentration equipment for processing, unfiltered wastewater often enters the evaporation and concentration stage directly. The solid impurities in the wastewater are prone to adhere to and scale on the inner wall of the evaporator. This not only reduces the heat transfer efficiency of the evaporator and leads to a significant increase in energy consumption, but also, when the scaling is severe, it can affect the normal operation of the equipment, shorten its service life, and increase the maintenance cost. Therefore, we propose a wastewater treatment evaporation and concentration equipment to solve the above problems. Utility Model Content

This not only reduces the heat transfer efficiency of the evaporator and concentration unit, leading to a significant increase in energy consumption, but also, when the scaling is severe, it can affect the normal operation of the equipment, shorten the service life of the equipment, and increase the maintenance cost of the equipment.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6As shown in the figure, this utility model embodiment proposes a wastewater treatment evaporation and concentration device, including an evaporator cylinder 1, a liquid receiving cylinder 2 installed on one side of the evaporator cylinder 1, a guide pipe 7 installed through the evaporator cylinder 1 and the liquid receiving cylinder 2, a first sealing plate 3 and a second sealing plate 4 respectively installed on the upper ends of the evaporator cylinder 1 and the liquid receiving cylinder 2 by bolts, a filter mechanism 5 installed on the upper end of the first sealing plate 3, a heater 13 installed on the lower end of the interior of the evaporator cylinder 1, a rotating shaft 11 movably installed in the middle of the interior of the evaporator cylinder 1, the upper end of the rotating shaft 11 being connected to the filter mechanism 5, a motor 10 installed on the lower end of the interior of the evaporator cylinder 1, the output end of the motor 10 being connected to the lower end of the rotating shaft 11, and a plurality of cleaning plates 12 installed on the outer side of the shaft 11, the cleaning plates 12 being movably located inside the evaporator cylinder 1, and the cleaning plates 12 being in contact with the inner wall of the evaporator cylinder 1.

[0023] like Figures 4 to 6 As shown, in another embodiment of this utility model, a discharge pipe 6 is installed through one side of the lower end of the evaporator concentrator cylinder 1. An exhaust pipe 8 and a discharge pipe 9 are installed through the upper and lower ends of the liquid receiving cylinder 2, on the side away from the guide pipe 7. The filter mechanism 5 includes a connecting cylinder 501, which is installed through the middle of the upper surface of the first sealing disc 3. A limiting block 502 is installed at the lower end of the connecting cylinder 501. A temporary storage cylinder 503 is installed inside the connecting cylinder 501, with its lower end fitting against the limiting block 502. A plurality of guide grooves 504 are provided on the inner wall of the connecting cylinder 501. A plurality of guide blocks 505 are installed on the outer side of the temporary storage cylinder 503, and the guide blocks 505 are respectively engaged inside the guide grooves 504. The temporary storage cylinder 503... The internal structure contains several filter layers 506. A drive shaft 507 is movably installed between the filter layers 506 and the temporary storage cylinder 503. The lower end of the drive shaft 507 is connected to the rotating shaft 11. The upper end of the drive shaft 507 is provided with a threaded hole 508. A cross scraper 509 is movably installed at the upper end of the internal structure of the temporary storage cylinder 503. The cross scraper 509 is in contact with the surface of the filter layer 506. A threaded rod 510 is installed at the lower end of the cross scraper 509. The threaded rod 510 is installed inside the threaded hole 508 by threads. A sealing cover 512 is installed at the upper end of the connecting cylinder 501 by threads. A feed pipe 511 is installed through the middle of the upper surface of the sealing cover 512. Valves are installed inside the feed pipe 511, the drain pipe 9, the exhaust pipe 8, and the discharge pipe 6, respectively.

[0024] Wastewater enters the temporary storage cylinder 503 of the filter mechanism 5 from the feed pipe 511. The filter layer 506 in the temporary storage cylinder 503 filters the wastewater to remove solid impurities and prevent solid impurities from entering the evaporator cylinder 1. This prevents impurities from adhering to and scaling on the inner wall of the evaporator, thereby improving the heat transfer efficiency of the evaporator, reducing energy consumption, extending the service life of the equipment, and reducing equipment maintenance costs.

[0025] When motor 10 starts, it drives shaft 11 to rotate. Shaft 11 drives transmission shaft 507 to rotate. When transmission shaft 507 rotates, due to the cooperation between threaded rod 510 and threaded hole 508, cross scraper 509 rotates in temporary storage cylinder 503, allowing cross scraper 509 to scrape and clean the surface of filter layer 506, preventing filter layer 506 from clogging, improving filtration efficiency and continuous working capacity of filter layer 506, and ensuring stable operation of equipment.

[0026] The filtered wastewater enters the evaporator cylinder 1, where the heater 13 heats and evaporates the wastewater. The evaporated water forms steam, which enters the liquid collection cylinder 2 through the guide pipe 7, thereby achieving the evaporation and concentration of the wastewater and separating the water and concentrate to achieve the purpose of wastewater treatment.

[0027] During the evaporation and concentration process, the rotating shaft 11 drives the cleaning plate 12 to rotate inside the evaporator cylinder 1. The cleaning plate 12 is in contact with the inner wall of the evaporator cylinder 1, which can promptly clean the small amount of impurities that may be attached to the inner wall, prevent the scaling from getting worse, keep the inner wall of the evaporator cylinder 1 clean, maintain good heat transfer performance, and ensure the normal operation of the equipment.

[0028] Inside the liquid receiving cylinder 2, the steam is cooled to form a liquid, which is discharged through the liquid discharge pipe 9, while the uncondensed gas is discharged through the exhaust pipe 8. The concentrated waste material inside the evaporator concentrator cylinder 1 is discharged through the discharge pipe 6. The processed products and waste gas are discharged in a timely manner, so that the equipment can operate continuously and stably.

[0029] The guide groove 504 and guide block 505 are used to guide the temporary storage cylinder 503 to move, and also to limit the temporary storage cylinder 503 to improve the stability of the temporary storage cylinder 503 when it works with the filter layer 506 to filter wastewater.

[0030] The working principle of this wastewater treatment evaporation and concentration equipment:

[0031] In operation, wastewater first enters the temporary storage cylinder 503 of the filter mechanism 5 through the feed pipe 511. The filter layer 506 inside the temporary storage cylinder 503 filters the wastewater. Simultaneously, the motor 10 starts, driving the rotating shaft 11 to rotate. The rotating shaft 11 drives the transmission shaft 507 to rotate. When the transmission shaft 507 rotates, due to the engagement of the threaded rod 510 and the threaded hole 508, the cross scraper 509 rotates inside the temporary storage cylinder 503, allowing the cross scraper 509 to scrape and clean the surface of the filter layer 506. Then, the filtered wastewater enters the evaporator concentrator cylinder 1, where the heater 13 heats and evaporates the wastewater, forming steam. The wastewater enters the receiving cylinder 2 through the guide pipe 7, achieving evaporation and concentration. Simultaneously, during the evaporation and concentration process, the rotating shaft 11 rotates, causing the cleaning plate 12 to rotate inside the evaporator cylinder 1. The cleaning plate 12 is in contact with the inner wall of the evaporator cylinder 1, which can promptly clean any small amount of impurities that may be attached to the inner wall, preventing further scaling. Finally, in the receiving cylinder 2, the steam cools and forms liquid, which is discharged through the drain pipe 9, while the uncondensed gas is discharged through the exhaust pipe 8. The concentrated waste material in the evaporator cylinder 1 is discharged through the discharge pipe 6, ensuring timely discharge of the treated products and waste gas, enabling the equipment to operate continuously and stably.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
