A support frame is placed at the lower part of the tank body, and the upper end of the support frame is fixedly connected to the support arc plate, and the support arc plate is fixedly connected to the outer wall of the tank body through the connecting arc plate. The utility model solves the problem that the stress at the contact part between the support frame and the outer wall of the tank body is large, which easily causes the tank wall to be deformed due to uneven force, and the storage inside the tank body needs to be connected to the conveying pipe when the material is discharged, which is cumbersome and complicated to use. "

[0004] In the process of realizing the present application, the inventors found that the prior art had the following problems: Although the above-mentioned comparative patent provides a steel-lined plastic storage tank that avoids deformation caused by high stress and uneven force at the contact part between the support frame and the outer wall of the tank body by setting a tank body, a feed pipe, a discharge pipe, a conveying pipe, a pipe rack, a support frame and a support arc plate, there is no stirring and cleaning mechanism in the tank, which makes it difficult to meet the needs of cleaning the plastic storage tank and preventing scale accumulation on the tank wall. Therefore, those skilled in the art provide a high-strength composite steel-lined plastic storage tank to solve the problems raised in the above-mentioned background technology. Utility Model Content
