Description

Technical Field

[0001] The utility model relates to the technical field of height-raising auxiliary chimneys in mining plants, in particular to a height-raising auxiliary device for dust removal chimneys in ore dressing plants. Background Art

[0002] The dust removal chimney of the ore dressing plant is a key facility for discharging dust-removed gas. Its design and operation are crucial to environmental protection, pollution prevention and control, and the normal operation of the production process. When designing a dust removal chimney, it is necessary to comprehensively consider parameters such as flue gas flow, temperature, pressure, and comply with environmental protection regulations. Factors such as the height, diameter, and structure of the chimney will also affect the dust removal effect.

[0003] During the chimney heightening and hoisting process, as the number of flange screw holes increases, each screw hole needs to be precisely calibrated, which not only increases the workload, but may also lead to error accumulation, thus affecting the accuracy of chimney installation. The calibration of multiple screw holes one by one leads to longer installation time, which may pose a serious challenge under tight construction schedules. In addition, the increased difficulty of calibration places higher demands on the technical level of the installers, and insufficient skills may lead to inaccurate calibration, affecting the use of the chimney. At the same time, this situation may also require more man-hours and higher-level technicians, thereby increasing installation costs. Utility Model Content
