Description

TECHNICAL FIELD

[0001] The utility model relates to filter cartridge installation equipment field especially, relates to a portable filter cartridge auxiliary installation calibration tool. BACKGROUND

[0002] Inorganic fiber filter cartridge is the core filter unit of filter cartridge dust collector, and its installation mode is similar to that of bag, and when installing, the filter cartridge is transferred to the inside of the clean gas chamber from the clean gas chamber manhole door by manual, is placed into the flower board hole in turn, and is fixed in position by using shaft shoulder bolt and pressing plate. Affected by the filter cartridge production and its own straightness and other characteristics, especially after the filter cartridge gasket is compacted and installed, the perpendicularity of the filter cartridge will change, resulting in that the spacing between part of filter cartridges is too small, and especially when dust cleaning is not timely or the dust cleaning effect is poor, dust bridging between filter cartridges is extremely easy to occur, and filter cartridge extrusion and fracture occur. Therefore, after the filter cartridge installation is completed, the installation personnel needs to enter the reactor chamber to check the spacing between the filter cartridges, and when it is found that the spacing at the bottom of the filter cartridge is less than 40mm, the installation personnel in the clean gas chamber is informed to loosen the nut to adjust the filter cartridge to meet the requirements and then is locked again.

[0003] At present, after the existing filter cartridge installation is completed, the installation personnel enters the bottom of the reactor chamber by the way of jumping the board, checks the filter cartridge above in the way of looking up, compares and observes the spacing between the filter cartridges, and then informs the installation personnel in the clean gas chamber to make corresponding adjustment. This checking and adjusting mode is mainly based on manual experience, is greatly affected by human factors, and is poor in precision and low in efficiency. When the installation personnel observes the filter cartridge from different angles or heights, the judgment of the spacing between the filter cartridges will have different results due to the influence of visual perspective, so that the filter cartridge that should be adjusted is not adjusted, and the filter cartridge that does not need to be adjusted is adjusted excessively, the checking process is extensive, the checking result is low in precision, the adjustment workload is large, and the stability of equipment operation is affected. Especially when the installation spacing is unqualified, dust bridging between filter cartridges is easy to occur if dust cleaning is improper after the equipment is put into operation, and filter cartridge extrusion and fracture occur.
