Installation and construction method of large disc dryer in limited space

Abstract

The invention discloses an installation and construction method of a large-sized tray dryer in a confined space. According to the method, a traction combined lifting and hoisting measure with a craneand a winch is adopted to smoothly transport large-tonnage equipment to a foundation according to a basic position and height of the equipment; the installation and alignment of a unit are completed with high quality, so that not only is the difficult construction problem of hoisting equipment in a limited space solved, but also the construction period is shortened, and the cost is saved; a pre-installation positioning technology of a base facilitates the position and alignment of the equipment and reduces the construction cost; and the method is high in success rate and wide in application range, and provides reference for the installation of large-sized equipment in confined spaces within a similar framework.

Description

technical field [0001] The invention belongs to the field of installation methods of equipment in a special environment, and in particular relates to a method of installation and construction of a large disc dryer in a limited space. Background technique [0002] The disc continuous drying machine is a multi-layer fixed hollow heating circular loading disc, rotating rake stirring, vertical continuous drying machine, which is developed on the basis of the intermittent stirring conduction dryer, and integrates a series of advanced technologies through continuous improvement. Drying equipment based on heat conduction. Compared with traditional drying equipment, it has the advantages of high thermal efficiency, low energy consumption, uniform drying, good product quality, small footprint, compact structure, less pollution, continuous production, convenient operation and wide application range, etc. It is widely used in chemical industry , dyes, pesticides, plastics, medicine an...

Problems solved by technology

[0003] In some fiber-grade polyphenylene sulfide resin projects, multiple large dryers will be installed. The largest dryer model is PLG disc dryer, with an overall size of Ф3800mm×8123mm and a weight of 25T. Its installation location is on the 10-meter floor If a large crane is used to directly hoist it to the foundation in the factory building, it is calculated that a truck crane of more than 260t is required, and the 16m beam at the reserved place needs to be removed and reinforced, such as figure 2 As shown, this method is time-consuming and expensive
