Precautions for installing dust collector bags

After all installation work of the dust collector (including insulation and anti-corrosion work) is completed, the installation of the dust bag can be carried out. First, remove the blowing pipe, and then install the filter bag. When handling and storing filter bags, please be careful to prevent them from coming into contact and colliding with surrounding hard and sharp objects. Do not step on or press heavily to avoid damage.

1. When storing dust removal bags, please keep them away from sources of fire, moisture, direct sunlight, and other strong light, and avoid squeezing heavy objects. Before installation, please check each filter bag to prevent mechanical damage.

2. The installation personnel should wear neatly and the pockets of their clothes should be clean. Do not carry cigarettes, matches, lighters, keys, knives, etc. to avoid falling into the filter bag (if debris falls into the filter bag, it must be removed). It is prohibited to install shoes with nails or hard soles. The personnel installing the filter bag should be fixed, the position should be fixed, and the responsibilities should be clear. Everyone should make a record of the dust removal bag they have installed and sign on the record book.

3. Installation environment requirements: There should be sufficient lighting at the installation site, and equipment or debris unrelated to installation should not be stored on site.

4. When installing dust removal bags, smoking is strictly prohibited, welding and cutting in any form are strictly prohibited, and any part is strictly prohibited. It is strictly prohibited to use lighters, matches, etc. for ignition and lighting when the power is turned off. After completing the installation work every day, it is necessary to count the installation tools to avoid loss, as the filter bags in the filter bags have been damaged.

5. Requirements for installing dust removal bags: It is recommended to have two people install them. One person folds the bag vertically and sends it into the hole of the flower board, while the other person grabs and opens the rolling filter bag. The cage frame should be aligned with the center, gently inserted, and kept vertical during installation.

6. Dust bag installation inspection: After installing the filter bag, check if the seams are sealed and if the sealing position is correct. Check if it is perpendicular to the trash can. If the bottom of the filter bag is found to be in contact or incorrect, please make a record and straighten it under the guidance of a dedicated person.

7. After installation, the flower board should be gradually covered with canvas to prevent debris from falling into the filter bag. When installing the blow pipe, please cover the flower board with canvas to avoid damaging the filter bag opening.

8. Special attention should be paid to installation: the centers of the blowing pipe hole, Venturi nozzle, filter bag holder, dust removal bag, and flower board should be consistent, with a deviation of less than 2mm.

To prevent damage to the dust collector bag, extra care should be taken from the beginning of installation. Tools with sharp edges, such as screwdrivers, should not protrude from the tool kit. Cover or remove all items with quick bites. When installing the dust removal bag, do not stand or kneel on the filter bag to prevent feet or heavy objects from squeezing the installed dust collection bag. Before installing the dust collection bag, please avoid damaging the filter bag. All seams of the dust bag should face in the same direction (returning to the air inlet).

Usually, the dust removal frame and dust removal bag are tightly matched. However, if the matching size of the two is too small, the size of the dust removal frame or bag should be checked, and the dust removal frame or bag with the wrong size should be scrapped (discarded filter bags or bag cages should be returned to the manufacturer in a timely manner). When installing the filter bag, if using a bagging tool to protect the filter bag, the filter bag spring expansion ring should be manually squeezed to greatly reduce the contact surface and flower plate hole. The spring expansion ring clamp is only inserted into the hole of the flower board, and then inserted into the dust removal bag. Note that after installing the bag cage on the flower board, it is necessary to visually inspect whether the bottom bag is in contact with the steel plates of the surrounding boxes in the ash hopper to prevent dust damage in the middle of the bag during operation.

A blowing pipe will be installed above each dust removal bag, and each blowing pipe will be connected to the air distribution box through a steel joint. The other end of the blowing tube has an adjustable fixed end, which is connected to the bracket of the clean air room (upper box). The blowing outlet of the blowing tube should be kept at the center of the filter bag.

Warning: Dust removal bags and bag cages should be placed indoors. After installation and cleaning, the inspection door should be closed. After installing the dust removal bag, welding, cutting, or grinding operations are not allowed.
