Description

Technical Field

[0001] The invention relates to the technical field of biodiesel equipment, in particular to a novel drying tower disc set. Background Art

[0002] The drying tower is a key equipment in the pretreatment section of biodiesel production. Its working principle is: the heated raw materials are transported to the upper disc sphere through pipelines, and then fall down step by step. In this process, water evaporates from the raw materials and is discharged from the tower body. The dried raw materials are transported to the lower equipment through the bottom pipeline of the tower. Obviously, for the drying tower to work efficiently, the raw materials need to be evenly distributed on the spherical surface of each disc in the disc group, so each disc in the disc group should be as horizontal as possible, which is a key component affecting the working efficiency of the drying tower.

[0003] The disc assembly of the traditional drying tower mainly has two types: single-piece welding and integral welding. When welding a single piece, each piece is different due to manufacturing errors and welding deformation, and position measurement errors are inevitable when welded to the inner wall of the cylinder. The integrally welded disc assembly also has manufacturing errors and welding deformation. After the disc assembly is welded into a whole, it is heavy and difficult to hoist. It is also impossible to adjust a single disc, and it is difficult to ensure the position of the disc assembly relative to the drying tower cylinder, which affects the production efficiency of the drying tower, and is inconvenient to maintain, increasing maintenance costs. Therefore, those skilled in the art provide a new type of drying tower disc assembly to solve the problems raised in the above background technology. Summary of the invention
