Abstract

The invention discloses an installation construction method of a large coal pulverizer. The method comprises the following steps: 1, carrying out basic inspection and acceptance; 2, unpacking and inspecting an apparatus; 3, paying off a line; 4, installing an anchor bolt; 5, installing an apparatus pedestal; 6, installing a main bearing pedestal; 7, installing a main bearing; 8, installing a rotation portion; 9, installing a transmission portion; 10, installing a cylinder lining board and a feeding and discharging port lining board; 11, installing a gear cover and other accessories; and 12, carrying out test driving. The installation construction method allows an apparatus body and transmission mechanisms to be assembled on the ground, integral hoisting is carried out after the assembling of the apparatus body and the transmission mechanisms, and local adjustment is carried out to solve a series of problems of need of the arrangement of a full framing scaffolding on the apparatus, long use time of large tonnage cranes, low installation precision and the like are solved, and good economic and social benefits are realized.

Description

technical field [0001] The invention relates to an installation and construction method of a large-scale coal pulverizer, which is suitable for the installation of a coal pulverizer in a large-scale coal chemical industry project, and belongs to the technical field of equipment installation. Background technique [0002] The successful commercialization of coal-to-olefins and the successful demonstration of coal-to-liquids have brought new coal chemical products to the market, competing with domestic and foreign petrochemical products, and will have a profound impact on my country's energy and chemical raw material supply structure. The industrialization demonstration of coal-to-olefins and coal-to-oil has been completed, and coal-to-synthetic natural gas and coal-to-ethylene glycol are also actively advancing. Under the trend of high oil prices and tight energy supply, the new coal chemical industry has opened up a new direction for the supplement and partial replacement of...
