Problems solved by technology

However, the grinding discs currently used cannot meet the needs of actual work. Conventional ball bearings are generally used as the supporting bearings of the dust collector. This kind of bearings is not only large in size but also short in life and high in cost.

Embodiment Construction

[0007] The present invention will be described in detail below in conjunction with embodiment:

[0008] The wear-bearing sheet of the present invention is composed of three layers of materials, the bottom layer is a steel plate layer, the middle layer is a copper alloy skeleton layer, and the upper layer is a polytetrafluoroethylene mixed wear-reducing layer. The upper polytetrafluoroethylene mixed layer is dipped and brushed with the mixed anti-friction material on the copper alloy skeleton by brushing, and then the mixed anti-friction material is firmly pressed into the copper alloy skeleton layer by pressing to form the upper polytetrafluoroethylene mixed layer. The specific manufacturing method of the wear-reducing sheet is as follows: first, the steel plate is machined into shape, and then copper is deposited on one side of the steel plate, and alloy copper is sintered on the surface of the copper by spraying and sintering. The intermediate alloy skeleton layer; brush and...

Abstract

A grinding plate for an electrostatic precipitator and its manufacturing method. The grinding plate is composed of three layers of materials. The bottom layer is a steel plate layer, the middle layer is a copper alloy skeleton layer, and the upper layer is a polytetrafluoroethylene mixed wear-reducing layer. The steel plate is machined into shape, and then electroplating copper on one side of the steel plate, and the alloy copper material is sintered on the surface of the electroplating copper by spraying and sintering to form an intermediate alloy skeleton layer; At least once brushed with polytetrafluoroethylene mixture and dried, then the surface is pressed into shape, and cured to form a layer of polytetrafluoroethylene mixed anti-friction layer, so that it has the characteristics of small size, light weight, wear resistance, Corrosion, long service life and other characteristics.

Description

technical field [0001] The invention relates to a grinding plate of an electrostatic precipitator capable of withstanding a relatively large working specific pressure and a manufacturing method thereof, in particular to a grinding plate of a large electrostatic precipitator and a manufacturing method thereof, which is a key component of the dust collector. Background technique [0002] With the continuous improvement of the degree of industrialization, environmental pollution has become a serious issue of concern. In order to effectively control the emission of factory exhaust gas, large-scale electrostatic precipitators appear under such conditions, and one of the key components of this precipitator is required to be able to withstand a huge working specific pressure of 100-1500 kg / cm. 2 And a sufficiently small dry friction coefficient of 0.05-0.1, it must ensure that the steel structure of the dust collector is not damaged during the process of thermal expansion and contr...
