A kind of pre-assembled tooling of barrel wall unit of thickener

Abstract

The invention relates to a cylinder wall unit preassembling tool for a thicker. The cylinder wall unit preassembling tool is characterized by comprising a plurality of upper cylinder wall supporting frames and a plurality of lower cylinder wall supporting frames. All the upper cylinder wall supporting frames and all the lower cylinder wall supporting frames are arranged at intervals and are distributed in an arc shape integrally. The cylinder wall unit preassembling tool further comprises an upper cylinder wall locating plate arranged horizontally, a lower cylinder wall top locating plate arranged horizontally, a plurality of gap locating plates used for controlling a gap between an upper cylinder wall and a lower cylinder wall, and a plurality of horizontal locating plates used for controlling the positions of horizontal connecting flanges of the upper cylinder wall and the lower cylinder wall. According to the preassembling tool, the upper cylinder wall and lower cylinder wall vertically-preassembling technology can be adopted for carrying out preassembling before final assembly is carried out, the upper cylinder wall locating plate and the lower cylinder wall top locating plate are utilized for carrying out lateral locating, the gap locating plates are utilized for locating upper cylinder wall pieces and lower cylinder wall pieces, the horizontal locating plates are utilized for locating the horizontal connecting flanges of the upper cylinder wall and the lower cylinder wall, lower cylinder wall bottom locating plates and lower cylinder wall locating bottom plates are utilized for locating the inner side and the bottom end of the lower cylinder wall, final assembly is achieved smoothly, the workload of aerial work in the final assembly process is greatly reduced, the working efficiency is improved, and operation is safer and faster.

Description

technical field [0001] The invention relates to a thickener, in particular to a pre-assembled tooling for the barrel wall unit of the thickener. Background technique [0002] The thickener is a solid-liquid separation device based on gravity settlement, usually a cylindrical shallow tank with a conical bottom built from concrete, wood or metal welded plates as structural materials. Its main structure is as figure 1 As shown, it is mainly composed of four parts: the cylinder wall unit a, the cylinder bottom unit b, the underflow cone c and the support structure d. The bottom of the cylinder structure composed of the cylinder bottom unit and the cylinder wall unit is supported by the support structure. An annular overflow groove is arranged on the inner wall of the cylinder wall, and an underflow cone is arranged in the center of the cylinder bottom unit. [0003] The thickener can concentrate the pulp with a solid weight of 10% to 20% through gravity sedimentation into an u...

AI Technical Summary

Problems solved by technology

However, there is a problem with such a production process: due to the large size of the thickener, the height will reach more than ten or even tens of meters, and a large number of high-altitude operations will be generated, and positioning is difficult, which greatly reduces the manufacturing quality and manufacturing efficiency. There is a big security risk

[0006] Therefore, it is imperative to research and develop a novel method or equipment for making the barrel wall unit of the thickener; however, no technical solutions identical or similar to those of the present invention have been found after retrieving relevant documents.
