Embodiment Construction

[0006] A method for treating the surface of the bag cage. After the welded bag cage is mechanically polished, phosphating, and dried, organic silicon powder is evenly sprayed on the surface of the bag cage under the action of electrostatic adsorption, and then baked at 220°C-250°C. In the oven, the powder is melted, leveled, solidified, cooled and attached to the surface of the cage, and the thickness of the silicone powder layer attached to the surface of the cage is ≥60um.

Abstract

The invention relates to a bag cage surface processing method which comprises the following steps: uniformly spraying organic silicon powder onto the surface of a bag cage under the action of electrostatic absorption after the welded bag cage is mechanically polished, phosphatized and dried, and then cooling and adhering the powder onto the surface of the bag cage after the powder is melted, leveled and solidified in a baking and roasting oven of 220-250 DEG. During the whole production process, no waste water, waste gas and waste is generated, and the environment is friendly and clean; and the surface of the bag cage after being sprayed by the organic silicon powder has strong corrosion resistant ability, the service life of the bag cage can reach more than 6 years, and protect a filter bag can be effectively protected, therefore, the user cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of manufacturing environmental protection equipment, in particular to a method for treating the surface of a bag cage used to support filter bags. Background technique [0002] For the bag cage used to support the filter bag, the existing surface treatment technologies are generally pickling, phosphating, and galvanizing. During the use of the bag cage with galvanized surface, the following problems will occur: after one or two years of use, the surface will have rust spots, that is, it will be corroded, especially in acidic and high water vapor dust collection conditions, the corrosion problem is particularly serious, and will directly As a result, the supported filter bag is quickly worn out. Therefore, the life of the galvanized bag cage itself is short; the life of the filter bag supported by it will also be worn due to the corrosion of the bag cage, and the life is shortened, which increases the mainte...
