The position of the weld 05 is shown in Figure 13 If the width of the weld 05 is too small, the integrally formed storage tank conical bottom 02 and the tank wall 01 are not tightly combined, which affects the strength of the whole mixing storage tank. The width of the weld 05 is set to at least 30 mm, so that the strength of the whole mixing storage tank can be ensured.

[0126] Further, the conical angle of the integrally formed storage tank conical bottom 02 is 90°, that is, the angle between any generatrix of the integrally formed storage tank conical bottom 02 and the central axis is 45°. Compared with other angles, the conical angle of the integrally formed storage tank conical bottom 02 is set to 90°, so that the force on the integrally formed storage tank conical bottom 02 is more uniform, and the integrally formed storage tank conical bottom 02 has better strength.

[0127] It is to be understood by those skilled in the art that the present application can be implemented by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments are merely exemplary and are not the only ones. All changes within the scope of the present application or equivalent to the present application are intended to be included in the present application.
