[0002] In the processing and production of rare metals, a large amount of pickling wastewater and lime milk wastewater need to be treated. Conventional treatment directly concentrates the two wastewaters into one pool, and then uses a stirring structure to ensure that they are fully neutralized through stirring and mixing, thereby reducing the direct discharge of polluting wastewater to the outside.

[0003] Moreover, in actual use, it is common to perform simple counter-flow convergence at the water outlet to achieve preliminary mixing, so as to shorten the subsequent stirring and mixing time; however, it also has certain defects, especially in the contact effectiveness of the counter-flow convergence, which has room for improvement.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 4 As shown, a specific embodiment of the present invention discloses a wastewater treatment pool confluence structure, including a first pipe 100, a second pipe 200, and a fabric cover 400 installed on a support frame 300; the fabric cover 400 is a cone-shaped structure, the axis of the first pipe 100 coincides with the axis of the fabric cover 400, and the bottom end of the first pipe 100 is arranged corresponding to the pointed cone portion of the fabric cover 400; the second pipe 200 is a ring-shaped structure, the second pipe 200 is a closed-loop structure around the axis of the first pipe 100, and the second pipe 200 is arranged around the upper outer side of the fabric cover 400; the second pipe 200 is provided with a drain outlet 210 that is closed-loop around the axis of the first pipe 100.

[0025] The above-mentioned wastewater treatment pool confluence structure has a simple structure. Through the cooperation of the first pipe and the cloth cover, a specific flow direction is defined, so that the first liquid is diffused and distributed along the cloth cover, providing a larger range.

[0026] The flow direction of the second liquid is also limited by the annular second pipe and the drain port, so that it is discharged in a closed loop and falls onto the fabric cover, thereby allowing the two waste liquids to fully contact and mix, achieving an effective primary mixing and neutralization effect.

[0027] Furthermore, the drain port 210 is provided in the middle of the inner wall of the second pipe 200. This structure allows the liquid to form an annular water curtain by overflowing, so as to facilitate sufficient mixing and contact with another solution distributed on the fabric cover.

[0028] Furthermore, a scraper 500 is provided on the top of the fabric cover 400, and the scraper 500 rotates around the axis of the fabric cover 400; the scraper 500 slides against the outer wall of the fabric cover 400 and the outer side of the drain outlet 210, and is used to scrape and clean the area where the solution is collected and neutralized; since it is mainly used in the treatment of waste liquid for acid-base neutralization, the original liquid or the substance produced by the neutralization reaction may form lumps, and the designed scraper can scrape and clean the contact area to prevent the accumulation of lumps or blockage of the drain outlet, thereby avoiding affecting normal drainage.

[0029] Furthermore, if Figure 5 、 Figure 6 As shown, the scraper 500 includes a sleeve 510 and a scraper 520 fixed on the outer wall of the sleeve 510. The sleeve 510 is rotatably sleeved on the bottom of the first pipe 100, and the scraper 520 slides against the outer wall of the fabric cover 400. The scraper 520 is provided with a bayonet 521 on one side of the inner ring corresponding to the second pipe 200, and the bayonet 521 slides against the inner and outer walls of the second pipe 200. Through the cooperation between the sleeve and the first pipe, the cooperation between the scraper and the fabric cover, and the cooperation between the bayonet and the second pipe, a plurality of cooperation and defined positions are formed, so that the scraper can be rotated and placed in the desired position, and its rotation direction is effectively limited, so that it can effectively scrape and clean the corresponding parts.

[0030] Furthermore, a pressure cover 530 is fixedly provided on the bottom outer wall of the sleeve 510. The shape of the pressure cover 530 is adapted to the top shape of the fabric cover 400. A distance is left between the inner wall of the pressure cover 530 and the inner wall of the fabric cover 400 to form a flow channel for liquid flow; the liquid discharged from the first pipe can be secondary limited to prevent the solution from impacting the cone head and causing outward expansion and splashing, ensuring that the solution flows along the outer wall of the cone and is fully diffused and distributed; and the bottom of the pressure cover is higher than the height of the drain outlet. In addition to satisfying the above-mentioned effects, it also prevents the pressure cover from blocking the liquid discharged from the second pipe, avoiding affecting the contact range of the two solutions.

[0031] Furthermore, a support ring is fixedly provided on the top outer wall of the sleeve, and a plurality of notches distributed in an array around the central circumference are provided on the outer side of the support ring, which serve as gripping parts to drive the entire scraping brush to rotate, thereby facilitating the scraping and cleaning operation; a limit block is provided on the outer side of the bottom of the first pipe, and the top surface of the support ring slides against the bottom surface of the limit block; and the support frame is a gantry structure, including two support bars arranged opposite to each other, and a frame bar fixedly mounted on the top of the two support bars; the first pipe is fixedly passed through the center position of the top frame bar, and docking plates are fixedly provided on both sides of the second pipe, and the docking plates are fixedly mounted on the support bars on both sides by bolts; the bottom of the fabric cover is also fixedly mounted on the support bar by bolts;

[0032] More specifically, during assembly, the scraper and brush must first be placed on the bottom of the first pipe, and then the second pipe and fabric cover are installed. The position of the scraper and brush is limited and clamped by the first pipe, the second pipe, and the fabric cover, so that the scraper and brush rotate around the axis of the first pipe to clean the outside of the fabric cover and the drain outlet.

[0033] Furthermore, a first shut-off valve 610 is installed at the end of the first pipe 100; a second shut-off valve 620 is installed at the end of the second pipe 200; the shut-off valves can be used to regulate the flow rate of the corresponding liquids to maintain effective coordination and meet the required neutralization mixing.

[0034] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
