Description

Technical Field

[0001] This utility model relates to the field of sewage treatment tank technology, and in particular to a high-strength steel sewage treatment tank. Background Technology

[0002] Steel wastewater treatment tanks are a common type of industrial and municipal wastewater treatment facility, characterized by high strength, corrosion resistance, and easy installation.

[0003] For example, Chinese patent CN217025391 U4 discloses a high-strength steel sewage treatment tank, belonging to the field of sewage treatment. It mainly includes a sewage treatment tank body, within which is provided one or more layers of anti-deformation frames. A mounting plate is fixedly installed on the uppermost anti-deformation frame, and a stirring mechanism and a dosing mechanism are provided on the mounting plate. The anti-deformation frame includes fixedly connected transverse and longitudinal supports, with their ends fixedly connected to the sewage treatment tank body. This invention, while ensuring that the sidewalls of the sewage treatment tank do not deform over long-term use and improving the safety of the sewage treatment tank, reduces the diameter of the reinforcing steel, reduces the amount of reinforcing steel used, thereby reducing the overall weight of the sewage treatment tank and saving production costs. This invention is mainly used for sewage treatment.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the lack of a protective structure for the weld seams on the inner side of the sewage treatment tank. Due to liquid pressure or defects in the weld (such as bubbles or incomplete welds), these weld seams are prone to becoming corrosion initiation points, ultimately leading to reduced strength and shortening the service life of the sewage treatment tank. Therefore, we propose a high-strength steel sewage treatment tank. Utility Model Content

[0030] This application provides a high-strength steel sewage treatment tank, which effectively solves the problem that the weld seam on the inner side of the sewage treatment tank body is not protected by a protective structure. Due to the liquid pressure or defects in the weld (such as bubbles or incomplete welds), the weld seam is prone to corrosion initiation point, which eventually leads to a decrease in strength and a shortened service life of the sewage treatment tank.

Due to the liquid pressure or defects in the weld (such as bubbles or incomplete welds), the weld seam easily becomes a corrosion initiation point, ultimately leading to reduced strength and shortening the service life of the sewage treatment tank. The overall idea is as follows:

[0033] To address the problems existing in the prior art, this utility model provides a high-strength steel sewage treatment tank, including a sewage tank body 1.

[0049] Tie rod 3: It is a stainless steel rod with C-shaped ends. It can hang the transverse beam 6 and prevent the transverse beam 6 from falling. The tie rod 3 and its load can press down the top of the sealing frame 10, so that the sealing frame 10 is tightly fitted to the inner wall of the sewage tank body 1.

[0050] Longitudinal beam 4: It is in the shape of angle steel and wraps around the four vertical side edges of the main body 1 of the sewage tank.

[0051] Cable tie beam 5: It is an X-shaped steel bracket, which is fixed to the two adjacent longitudinal beams 4 by welding, and the upper and lower sides are respectively welded to the two adjacent transverse beams 6;

[0052] Transverse beam 6: is a steel square bar, which is fixed at both ends to the two adjacent longitudinal beams 4 by welding;

[0053] Wastewater inlet pipe 7: It is a steel pipe with a flange welded to one end and the other end fixed to the main body of the wastewater tank 1 by welding;

[0054] Wastewater discharge pipe 8: It is a steel pipe with a flange welded to one end and the other end fixed to the main body 1 of the wastewater tank by welding.

[0055] Sewage pipe 9: It is a steel pipe with a flange welded to one end and the other end fixed to the sewage tank body 1 by welding. It is installed vertically at the bottom center of the sewage tank body 1. An end cap is fixed to the other side of the flange by multiple bolts for sealing.

[0063] Working principle:

[0064] The first step involves welding the longitudinal beam 4, the diagonal tie beam 5, and the transverse beam 6 into a single unit, which is then fitted over the four outer walls of the main body 1 of the sewage tank, thereby increasing the strength of the main body 1. By placing multiple tie rods 3 on top of the main body 1 of the sewage tank and securing the uppermost transverse beam 6, the longitudinal beam 4, the diagonal tie beam 5, and the transverse beam 6 will not fall off. When it is necessary to disassemble the longitudinal beam 4, simply remove the tie rods 3 and then pull the longitudinal beam 4, the diagonal tie beam 5, and the transverse beam 6 out from above the main body 1 of the sewage tank as a whole. The pulling force exerted by the multiple tie rods 3 on the upper transverse beam 6 can also improve the strength of the upper edge of the main body 1 of the sewage tank.

[0065] The second step involves designing a sealing frame 10 that aligns with the weld seam on the inner wall of the main body 1 of the sewage tank. Then, a rubber strip is bonded to the outer wall of the sealing frame 10. Next, the sealing frame 10 is pressed down by the pull rod 3 and its load, so that the rubber strip on the sealing frame 10 is tightly attached to and covers the weld seam, preventing the weld seam from being corroded and improving its service life.

[0066] The third step involves starting the motor 11, which, through the transmission of the first gear 14 and the second gear 15, causes the stirring roller 16 to start rotating and stir the sewage inside the sewage tank body 1.

[0067] The fourth step involves adding chemicals into the hopper 13, which are then transported through a plastic hose and rotary joint 12 to the mixing roller 16. Finally, the chemicals are discharged through the through-hole on the mixing roller 16, making the discharged chemicals more dispersed and facilitating thorough mixing, thereby improving the efficiency of wastewater treatment.

[0068] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
