Under normal circumstances, the dust bag is gradually worn, the main cause of wear is the grinding force of dust, high temperature caused by filter material deterioration and chemical corrosion, when the dust grinding force is very strong, the bottom of the bag wear the most serious Increased filter capacity due to increased system capacity can also accelerate wear.
The dust collector cannot work with broken bags, otherwise it will speed up the scrapping of the dust collector. When a small area of an individual bag breaks, the old hole or the new material can be used to fill the hole. The method of filling holes is to use a silicone rubber compound for bonding, as long as the temperature and chemistry of the adhesive are used. Performance and process conditions can be adapted.
When most of the bags are damaged, they should be replaced completely (when the filter material is used for a long time, the fine dust accumulated in the filter layer will reduce the air permeability, and when the air volume of the system is affected, it should be replaced if it is not damaged) The replacement bag is best performed when the dust collector stops working. At this time, the dust removal controller should be closed, and the top manhole door should be opened to remove the cloth bag. When disassembling the bag, the bag cage should be taken out first, and then the cloth bag can be taken out of the mouth. The spring ring is shaped into a concave shape and the cloth bag is pulled upwards. Before installing the new cloth bag, the dust on the flower plate hole should be cleaned.
How to install a cloth bag and remove the skeleton:
The installation of cages and bags is the least careful and careful work in all installations, so it should be placed at the end of the installation. When installing, the bag must not collide with the hard objects, and the hooks should be caught. Even small scratches will make the bags. The life expectancy has been greatly reduced. The method for installing the cloth bag is to put the cloth bag into the bag room from the hole of the flower plate of the box first, then squeeze the spring ring at the upper part of the bag mouth into a concave shape, put it into the flower hole plate of the box body, and then restore the spring coil to make it Press tightly on the circumference of the flower hole, and then gently insert the bag cage from the mouth of the bag until the cover on the upper part of the bag cage actually presses on the flower plate hole in the box. In order to prevent the bag from being stepped on, it is required to install a bag cage for each bag.
If the dust collector cannot be stopped when the bag is replaced, the rooms shall be separated off-line separately, and then the compartment shall be replaced with a replacement bag. The isolated room shall be such that the poppet valve is closed and the pulse valve does not work (for insurance purposes, it shall be Room pulse valve power off). When disassembling the bag, because the bag mouth has a small amount of negative pressure, special care should be taken not to drop the bag into the ash bucket.
