The bag cage, also known as the filter bag keel (skeleton), is one of the most important accessories used on the bag filter to ensure the normal operation of the filter bag. The quality of the bag cage production and installation directly affects the dust removal effect and efficiency of the bag filter. The bag cage, also known as the filter bag keel (skeleton), is one of the most important accessories used on the bag filter to ensure the normal operation of the filter bag. The quality of the bag cage production and installation directly affects the dust removal effect and efficiency of the bag filter.
The bag cage can be divided into round and flat, long and short, single and multi-section, etc. according to shape, size and structure. The following Jinri combines the production process of the bag cage to make a light analysis of the quality control of the bag cage.
I. Design Under normal circumstances, we use a circular bag cage for the spray dust collector. According to the filter bag technical scheme, the diameter, length and structure of the bag cage are selected. For the rotary jet dust collector, the flat shape is used. The bag cage, the structure, the number of sections, and the length vary with the specific design.
In the design of the bag cage, it is necessary to understand the actual working conditions of the dust collector accurately and comprehensively, in order to correctly select the raw materials and spraying materials of the bag cage, and the structural strength requirements of the bag cage determine the structure of the bag cage. Reasonable design is the prerequisite for ensuring the normal operation of the bag cage and ensuring the high quality operation of the dust collector in the future.
Second, production 1, raw materials. Quality raw materials are the basis for producing qualified products. Understand the performance of the raw materials used, and after the trial production, the production technical parameters can be reasonably formulated.
2. Commissioning of production equipment. The quality of equipment debugging determines the quality of the bag cage.
3. Production process. Properly arranging the process path is the key to quality assurance. The quality of each process will affect the quality of the finished product. Therefore, when installing the equipment, it is necessary to consider the process arrangement of the production process. It must be fast and orderly, but also easy to inspect and supervise, waste, defective products and finished product partition pendulum. In order, the logo is set up for easy differentiation and post-processing.
Third, painting The quality of the coating plays a vital role in the quality, performance and service life of the bag cage. Construction and quality control must be organized in strict accordance with the requirements of the coating process.
1. Surface treatment: The oil, rust, oxide scale and other impurities on the surface of the bag cage are generally cleaned by chemical treatment to eliminate the factors affecting chemical bonding and polarity bonding.
2. Select the coating construction method: According to the working condition of the dust collector, determine the coating material of the bag and the coating of the bag cage. We generally use galvanized and sprayed silicone.
3. Quality control of the coating process: In strict accordance with the construction process requirements of the coating, the pretreatment, construction environment, process parameters, handling, rework, etc. are supervised and inspected to ensure the quality of the bag cage.
4. Transportation The bag cages are usually transported over long distances from the production factory to the installation site. In this process, loading, unloading and transportation often damage and damage the bag cage, so appropriate measures must be taken to prevent damage and damage. We use a long plastic bag set for the bag cage and seal the bag mouth. At the same time, we use the special bag cage turnover box to avoid the most loss.
V. Installation Installation is an important part of the dust collector manufacturing. There is a common understanding in the dust removal industry: the quality of the dust collector is three-point production and seven-point installation. The installation of the bag is the most important part of the installation of the bag filter, and the installation of the bag will determine whether the bag can work normally and for a long time during the service period.
1. Inspection before installation: Before installation, the bag cage used must be carefully inspected. 2. Check the bag cage during installation. 3. Review after installation. Conclusion: In summary, design, fabrication, installation, and Every aspect of the material will have an impact on the quality of the bag. We believe that only improving the quality control of the bag from production, manufacturing to installation is the key to effectively controlling the quality of the bag.
