The frame of stainless steel dust collector uses iron wire or stainless steel wire with sufficient strength and rigidity. Galvanization, plastic spraying, silicone plating, etc. Technically processed skeleton can replace stainless steel skeleton. The skeleton is also called a dust removal skeleton, a dust removal frame, and a dust bag cage. The frame of the stainless steel dust collector is the ribs of the filter bag. It should be lightweight and easy to install and maintain. The quality of the flat stainless steel frame directly affects the filtering status and service life of the filter bag.
The quality of the stainless steel dust collector frame directly affects the working status and service life of the filter bag. The annual production capacity of our company's dust collector frame is 1.5 million meters. The post-treatment is galvanized or plastic sprayed on the surface, or according to the requirements of different working conditions of customers. Commonly used dust removal skeletons are circular skeletons, trapezoidal skeletons and spring skeletons.
(1) The influence of the size of the dust removal skeleton: In the geometric size of the dust removal skeleton, the diameter of the dust removal skeleton, the gas inlet, and the shape and size of the exhaust pipe are important influencing factors.
(2) The influence of gas parameters on the performance of the dust removal framework: including the influence of gas flow rate, the influence of gas dust concentration, the influence of gas moisture content, the influence of gas density, viscosity, pressure, temperature, etc.
(3) the influence of the physical properties of dust on the dust removal framework
(4) The effect of the roughness of the inner wall of the dust removal framework: The dust particles concentrated near the wall surface will cause swirling due to the rough surface, causing some dust particles to be thrown into the rising airflow and entering the exhaust pipe, which reduces the dust removal efficiency.
The cage type dust removal framework requires that the support ring and longitudinal ribs are evenly distributed, and that it has sufficient strength and rigidity, can withstand the pressure of the filter bag in the filtering and dust removal state, and can prevent collisions during normal transportation and installation. Damage and deformation caused by shock and impact.
All the welding points of the filter bag frame should be welded firmly, and no desoldering is allowed. Welding and missing welding are not allowed.
The surface of the filter bag frame and the bag contact surface should be smooth and smooth, no welding scars are allowed, unevenness and burrs.
The tension spring frame must have sufficient number of turns and elasticity, and the distance must be even after opening.
The surface of the filter bag frame is anti-corrosion treated, and electroplated according to different needs. Plastic spraying or painting, if used for high temperature, its anti-corrosion should be clear to meet the requirements of the use temperature.
◆ The verticality of the dust bag cage is 6M plus or minus 1mm.
◆ The dust bag cage has two sections or three sections.
◆ The dust-removing bag cage is more than 3 meters in length and wears a steel-made one-form pipe.
◆ Dust removal bag cage has galvanized, plastic sprayed and silicone treatment.
