Method for replacing filter bags of bag-type dust collector

Abstract

The invention provides a method for replacing filter bags of a bag-type dust collector. The method comprises the following steps of: step 1, a special dismantling tool is manufactured, wherein the dismantling tool comprises a wedge-shaped vibration head, the vibration head is connected to the lower end of an impact rod, and the impact rod is connected with an impact mechanism; step 2, a vibrationhead is inserted into adhesion positions of bag cages and a partition plate; step 3, an impact mechanism is started to drive the vibration head to vibrate, so that the adhesion positions are loosened,and the ends of the bag cages are separated from the partition plate; step 4, the bag cages are drawn outwards, and the filter bags are taken out from holes of the partition plate; and step 5, the filter bags are replaced, and novel filter bags and bag cages are installed into the fixing holes of the partition plate. The method provided by the invention has the following beneficial effects: the special dismounting tool is manufactured and used, so that the bag cages adhered to the partition plate can be rapidly and efficiently dismounted; and different vibration head blade parts are used, sothat damage to the bag cages in the dismounting process is avoided.

Description

technical field [0001] The invention relates to a replacement method, in particular to a filter bag replacement method of a bag filter. Background technique [0002] The bag filter is a dry dust filter device, which uses the filter function of the fiber fabric to filter the dusty gas, and the key components are the filter bag and the bag cage. Because the filter bag is soft, a cylindrical bag cage is usually installed inside the filter bag. The head of the bag cage fixes the filter bag and hangs on the partition to support and prevent the filter bag from collapsing. [0003] Because the operating environment of the dust collector is very complicated, the high temperature of the gas to be dedusted and the acidic substances contained in it often cause the contact part between the partition and the bag cage to stick, and it is difficult to take out the bag cage from the partition when replacing the filter bag. Due to the large number of filter bags and the limited downtime, ho...

Problems solved by technology

[0004] At present, destructive methods are commonly used to remove the stuck cage, such as using a crowbar or an iron-handled screwdriver to hit the contact surface of the cage and the partition, and pry up the edge of the cage until the cage is separated from the partition. Although the cage can be successfully removed Pull out from the partition, but the work efficiency is low, and it is easy to cause damage to the bag cage, which greatly increases the replacement amount of the bag cage, and the cost remains high
