Calculation of the cone bottom angle in a cone-bottom sedimentation tank
Thread Content
The diameter of the cone-bottom sedimentation tank is 4 meters and its height is 7 meters; the density of the material inside the tank is 0.98. What should be the appropriate angle of the cone bottom? How to calculate it?
If it is a sedimentation tank, it is recommended to use a conical head with folds of α=45°, and the fold radius at the larger end should be 450 mm. If it is at atmospheric pressure, the wall thickness should be no less than 12 mm. If you want to conduct an accurate calculation, use 0.07 MPa as the design pressure for the head section. In actual calculations, the cylinder thickness is kept small, mainly due to stiffness considerations. If you use 12mm, no external reinforcement is required.
