Problems solved by technology

[0009] The purpose of the present invention is to solve the problems of vibration and noise, short plant life and high maintenance cost in the existing coal washing and preparation plant due to unreasonable design, and to invent a method that completely separates the external plant structure from the internal production structure. The external structure does not bear the vibration load, and the modular construction method of the coal washing plant can greatly reduce the negative impact of vibration

example

[0050]Now take the main workshop of Yidong Coal Group Kaolinite Concentrator as an example to calculate. The construction site of the project is Xuejiawan Town, Zhungeer Banner, Inner Mongolia, and it is a modular structure. The outside is a closed enclosure with a door-type steel frame, and the inside is an independent module of various processes. The axial length of the outer frame is 98m. The span is 29m and the height is 35m. The outer frame area is 2842m2, about 99500m3. With 20T bridge crane. It contains 3 module equipment supports, A module primary selection system; B module reselection system and filter press workshop module. The three modules are independent steel frame equipment supports.

Abstract

A washing selecting coal plant modularization building method is characterized by comprising the following steps that first, a main plant house outer frame module is mounted, a traveling trolley is mounted; second, washing selecting coal equipment which needs to be mounted is divided into a plurality of sets according to a washing selecting coal production technology; third, a steel structure frame type mounting frame module is designed for each set of washing selecting coal equipment; fourth, the mounting frame modules are mounted in advance or conveyed into the mounted main plant house outer frame module to be mounted on site, mounting of the mounting frame modules is completed; columns of the mounting frame modules are fixedly connected with a foundation, so the vibration generated by the washing selecting coal equipment is directly transmitted to a base, influence of generated vibration on the main plant house outer frame module is avoided, service life of the main plant house outer frame module is prolonged; fifth, the washing selecting coal equipment is arranged on the mounting frame modules, and machine test operation is carried out. According to the washing selecting coal plant modularization building method, cost is lowered, resonance is reduced, and service life is prolonged.

Description

technical field [0001] The invention relates to a building and equipment installation technology, in particular to a method for installing and constructing a steel structure frame factory building and its equipment, in particular to a modular construction method for a coal washing and preparation plant. Background technique [0002] At present, the main workshop of the coal preparation plant is a building where coal preparation equipment is placed according to the requirements of the coal preparation (washing) process. At present, frame-type reinforced concrete structures or frame steel structures are generally used. Due to the large size and heavy weight of coal preparation equipment, And strong vibration loads will be generated during the working process. When the vibration frequency of some equipment is the same as that of the plant structure, resonance will occur. The resonance not only affects the normal work of equipment and operators, but also causes damage to the pla...
