Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a PAM uniform feeding device for sewage treatment. Background Art

[0002] Today, when water resources are extremely precious, sewage treatment and reuse have become a major issue in the world. Among the various sewage treatment schemes currently available, the use of flocculants and coagulants is an indispensable auxiliary measure. Therefore, the equipment used to dissolve and add these substances is very common in sewage treatment projects.

[0003] In the past, in traditional sewage treatment, chemicals were added directly into the sewage through pipes. The problem with this method is that the chemicals were unevenly distributed in the water and could not fully exert their effects. This not only directly affected the treatment results, but also resulted in a waste of chemicals.

[0004] The existing patent (Announcement No.: CN216853119U) discloses a PAM uniform dosing device for sewage treatment. By opening multiple dosing holes at equal angles on the dosing ring, the agent can be evenly integrated into the sewage. By injecting water into the through-hole of the flushing water pipe, the agent retained inside the dosing ring can be discharged from the dosing holes, thereby preventing the agent from being blocked in the dosing ring.

[0005] In response to the above problems, existing patents have provided solutions, but they are not convenient for controlling the amount of reagents added. When treating sewage, if the amount of reagent added is too little, the flocculation effect may not be fully exerted, resulting in the suspended matter in the sewage not being able to effectively coagulate and precipitate, affecting the effluent water quality. If the amount added is too much, it will not only cause waste of reagents and increase treatment costs, but may also cause the sludge volume to increase, making subsequent treatment more difficult, affecting the sewage treatment effect, and reducing the practicality of the device.

[0006] Therefore, a PAM uniform dosing device for sewage treatment is proposed. Utility Model Content

When treating sewage, if the amount of chemical added is too small, the flocculation effect may not be fully exerted, resulting in the suspended matter in the sewage not being able to effectively coagulate and precipitate, affecting the water quality of the effluent. If the amount added is too large, not only will the chemical be wasted and the treatment cost increased, but the sludge volume may also increase, resulting in increased difficulty in subsequent treatment, affecting the sewage treatment effect, and reducing the practicality of the device.

[0034] In this embodiment, the rotating motor 802 drives the rotating rod 804 to rotate, thereby driving the leakage shielding plate 805 to rotate, so that the PAM solution inside the reaction tank 6 flows smoothly into the inside of the observation tube 801. Under the action of the strip glass 10, the liquid level of the PAM solution can be visually observed, so that the operator can make adjustments according to actual needs to achieve accurate dosing, avoid overdosing or underdosing, and improve the effect and stability of sewage treatment. Then, through the coordinated use of the cross connecting plate 806 and the stirring blade 807, the cross connecting plate 806 drives the stirring blade 807 to rotate, which can drive the PAM solution to be evenly stirred, prevent the PAM solution from settling and agglomerating, and improve the convenience of using the quantitative component 8.

[0035] Specifically, such as Figure 5 As shown, a rotating groove 11 for cooperating with the rotating block 905 is opened on the top of the inner wall of the liquid storage cylinder 906 , and the surface of the rotating block 905 contacts the inner wall of the rotating groove 11 .

[0036] Specifically, such as Figure 4 As shown, a mounting hole 12 for cooperating with the infusion pump 901 is opened on the top of the observation tube 801 , and the surface of the infusion pump 901 contacts the inner wall of the mounting hole 12 .

[0037] In this embodiment, the infusion pump 901 is used in conjunction with the mounting hole 12 so that the surface of the infusion pump 901 contacts the inner wall of the mounting hole 12, which can make the connection of the infusion pump 901 more firmly, so that the PAM liquid inside the observation tube 801 can flow smoothly into the inside of the infusion main tube 903, thereby improving the smoothness of the flow of the PAM liquid.

Furthermore, the reaction tank 6 cooperates with the fixing hole 15 to make the surface of the reaction tank 6 contact the inner wall of the fixing hole 15, making the connection between the reaction tank 6 more secure, thereby ensuring the stability and reliability of the reaction tank 6 during operation and improving the stability of the device.

[0041] Working principle: When treating sewage, the rotating motor 802 drives the rotating rod 804 to rotate, driving the leakage shielding plate 805 to rotate, so that the PAM solution inside the reaction tank 6 flows smoothly into the inside of the observation tube 801, and under the action of the strip glass 10, the liquid level of the PAM solution can be visually observed, so that the operator can make adjustments according to actual needs to achieve accurate dosing and avoid overdosing or underdosing. Then, the cross connecting plate 806 and the stirring blade 807 are used in conjunction with each other, so that the cross connecting plate 806 drives the stirring blade 807 to rotate, which can drive the PAM solution to be evenly stirred and prevent the PAM solution from settling and agglomerating. The controller 13 and the detection rod 14 are used in conjunction with each other, so that the controller 13 can automatically adjust the working state of the infusion pump 901 according to the parameters in the storage tank 1 fed back by the detection rod 14, so that the PAM solution can be controlled more accurately. The amount of liquid delivered is reduced, thereby reducing the difficulty and labor intensity of manual operation. By cooperating with the infusion pump 901 and the delivery tube 902, the PAM liquid inside the observation tube 801 can flow smoothly into the interior of the infusion main tube 903. Under the action of the infusion branch tube 904, the PAM liquid can flow evenly into the interior of the liquid storage cylinder 906, so that the PAM liquid can react smoothly with the sewage. Then, by cooperating with the liquid storage cylinder 906 and the nozzle 907, all-round spraying can be achieved, and the PAM liquid can be evenly sprayed inside the storage tank 1. By cooperating with the rotating block 905 and the rotating groove 11, the rotating block 905 can move smoothly under the restriction of the rotating groove 11, so that the liquid storage cylinder 906 can rotate smoothly under the action of the PAM liquid, driving the nozzle 907 to rotate, increasing the spraying range, and ensuring that the PAM liquid can fully contact the sewage.
