The galvanizing and dust removing framework adopts cold galvanization, also called electrogalvanizing. Electrolytic equipment is used to remove the dust removing framework after degreasing, pickling, and then put it into a solution containing a zinc salt. Connect the anode of the electrolytic equipment and place a zinc plate on the opposite side of the pipe When the positive electrode connected to the electrolytic equipment is connected to the power source, a directional movement of the current from the positive electrode to the negative electrode will deposit a layer of zinc on the dust removal framework. The galvanized dust-removing framework has a smooth appearance, no zinc tumors and burrs, and is silver-white or colored. It has acid and alkali resistance and is currently a commonly used dust-removing framework.
The surface of the galvanized dust removal framework in contact with the filter bag should be smooth and smooth. Welding scars, unevenness and burrs are not allowed, so that the dust removal filter bag passes the strong wind pressure of the main fan of the dust collector and the anti-air blower dust or pulse valve spray blower. When the ash is repeatedly sprayed and cleaned, or when it is rubbed with the bag duster, it will not be damaged by friction with the dust removal framework.
Technical requirements for galvanized dust removal framework:
1. It should have sufficient strength, stiffness, verticality and dimensional accuracy to prevent compression deformation, damage during transportation, filter bags contacting each other after loading into the dust collector, difficulty in bagging, and friction of the bag frame;
2. The surface of the filter bag dust removal framework is treated with anti-corrosion, which can be sprayed or galvanized. The anti-corrosive treatment agent for high temperature should meet the needs of high temperature;
3. All the solder joints are firm, no desoldering, false soldering and missing soldering are allowed;
The development trend of galvanized dust removal framework technology is shown in the following aspects: high temperature and high humidity, strong corrosive framework and filter material.
The galvanized dust removal framework is also called dust removal cage. It is welded and formed by special equipment at one time. The dust removal framework is the ribs of the filter bag. The quality of the dust removal cage directly affects the working status and service life of the filter bag.
Galvanized dust removal framework features: firm welding, smooth and straight appearance, light application, easy to install and maintain. Dust removal cage bone specifications: round, oval, flat, envelope-shaped, various frames customized according to customer requirements.
Galvanized dust removal framework raw materials: low carbon steel wire, galvanized steel wire, stainless steel wire, etc. Dust removal bag cage structure: There are reasonable structural methods such as multi-section type, venturi tube, protective short tube, detachable type, plug-in type, and chuck type.
