The frame of the dust collector is the rib of the filter bag. It should be light and easy to install and maintain. The quality of the frame directly affects the filter bag filter status and service life. Use wire or stainless steel wire with sufficient strength and rigidity. The precipitator skeleton has a high production capacity. It is adept at making various kinds of trapezoidal dust-removing skeletons, flat dust-removing skeletons and other special-shaped dust-removing skeletons, and can also be designed and manufactured according to user requirements. The precipitator frame has the advantages of high temperature resistance, corrosion resistance, anti-condensation, thermal instability, good dust stripping, long service life, and low energy consumption for cleaning. The precipitator frame adopts a flat structure. The distribution of longitudinal reinforcements and counter-expansion rings of the cage is average, and it has enough strength to prevent damage and deformation. In order to ensure the strength of the steel wire and improve the appearance quality, we use φ6.5 yuan steel to draw ( Pull to φ3mm), and later in the assembly of the body on the welding of the tire, grinding to achieve the technical requirements. The quality of the skeleton directly affects the working condition and service life of the filter bag. Post-treatment is galvanized.
Precautions for choosing a filter frame:
The use of a good dust collector frame is an important factor in the daily operation of the dust collector. Different bag filter types with different cleaning methods should choose different types of filter media for different cleaning energy and filter bag deformation characteristics. For ordinary filter surface coating, calendering and other post-treatment can also improve the wear resistance. For glass fiber filter, silicone oil, graphite, polytetrafluoroethylene resin treatment can improve wear resistance, folding resistance. However, when the film-coated filter is used in a condition with strong abrasion, the film will be prematurely worn and the film will be lost.
The precipitator skeleton plays a comprehensive role in the short-range trapping mechanism of over-precipitator dust, direct trapping, diffusion settlement, inertial collision, and electrostatic adsorption. When the dust-laden air passes through filters such as meshes, fabrics, non-wovens, and foams, the dust is trapped in the dust layer formed inside or on the surface of the filter, and the filter layer formed on the upper layer of the powder is removed from the air stream. Separated. Vibrating back-flushing and bag-type dust collectors refer to bag dust collectors that have the dual action of vibration and reverse air flow. The vibration makes the dust cake loose and the counter-air flow makes the dust escape. The two methods cooperate with each other to improve the cleaning effect, especially for the fine-grained viscous dust. The principle of the filter material selection for such dust collectors is generally the same as that of the chamber backflush dust collectors, and the main selection is satin (or twill) woven filter material.
Dust collector skeleton common problems and solve problems:
1. Establish a regular maintenance system for the framework of the dust collector so that problems can be discovered in time and major accidents can be prevented.
2. It is forbidden to stack flammable and explosive materials around the frame of the dust collector. The ventilation is in good condition.
3. Regularly check the state of the dust collector’s seal and the operation status of the air net (including the fan).
4. Regularly check the dust filter bag and replace it in time when it is damaged. Pay attention to the dry, ventilated and dustproof storage of the backup dust bag and check it regularly.
5. The dust collector skeleton regularly cleans the air source processor of impurities and water.
6, regular refueling transmission, after the end must pay attention to dust, close the access must be installed seals.
7. Keep the pulse controller and solenoid valve clean, free of dust and dirt, and periodically check the control coil on the solenoid valve.
8. The dust layer on the surface of equipment and air duct should be cleaned immediately.
Precipitator Skeleton Raw material Carbon steel wire or stainless steel wire has a lot of oil pollution. Before use, it is necessary to use acid washing and phosphating for decontamination and rust removal. In the process of welding the frame of the dust collector, there should be no thorns and welding welds and no welding point. The entire frame structure is firm and firm and stable in shape. The line of the dust collector skeleton should be cleaned, otherwise it will scratch the dust collector bag to reduce the use time of the filter bag and reduce the dust collection effect of the filter bag. Dust removal skeleton raw materials are high quality galvanized steel wire, low carbon steel wire, stainless steel wire and so on. Dust removal frame material generally adopts cold drawn iron wire or stainless steel wire with sufficient strength and rigidity. It is welded with a high-frequency welding machine once to form the skeleton, the diameter is generally 2.5-4.0, other specifications can be customized, the appearance of anti-corrosion treatment is not the same, there is galvanization, spray , plating silicone and other processing methods. According to the material can be divided into stainless steel dust collector skeleton and wire dust collector skeleton.
Dust collector skeleton plays an important role and performance in practical use. It can accurately grasp and act according to a certain form and situation, can adapt to the changes in the market, and fully demonstrate certain trends and roles in dust removal work. According to the market situation, we should have a good grasp and role. With the development of dust removal technology and the increasing demand for environmental protection, the application scope of the dust remover skeleton has become more and more extensive. At present, it has been possible to use the dust collector skeleton to handle high temperature, high humidity, adhesion, explosion, abrasive smoke, and even filtration. Ultra-fine dust air. The precipitator frame is used in different industries. It plays an important role in the industry according to its own characteristics and advantages, and dust is removed according to different conditions to ensure the cleanliness and sanitation of the environment.
In the operation of the precipitator frame, a pulse cleaning method with a strong cleaning ability is adopted, and a blast cleaning control system is assembled. The cleaning efficiency is improved, which ensures the low resistance operation of the filter cartridge, reducing the difference in resistance between the electricity and the filter, and making the life of the filter cartridge mostly escape the small fish. The skeleton of the dust collector is like fishing with a net with a small mesh. Although both sizes can be cleaned, but the nets of both sizes are burdened with the problem of electrostatic precipitators and precipitator frame working conditions in the comparators. Secondly, how to implement two dust removal methods to connect the bag dust removal area The flow rate and dust concentration of each filter bag are evenly distributed to increase the bag filter wind speed, and effectively reduce the resistance of the electrostatic bag composite filter frame system. In the mechanism of dust collection, the filter characteristics of the bag are changed by the charged dust, a new filtration mechanism occurs, and the load factory is utilized.
