Problems solved by technology

In actual production, due to uneven application of anti-seepage agent, it often causes cracks during welding due to carburizing and quenching of the head, which seriously affects the cathode rapping transmission of the dust collector and affects the dust removal effect. Therefore, it is necessary to rap the cathode of the electrostatic precipitator Wheel pin processing technology to take further improvement

Embodiment Construction

[0011] Such as figure 1 The schematic diagram of the cathode rapping needle wheel pin processing is shown. The cathode rapping needle wheel pin is composed of a pin rod (1) and a pin cap (2). The pin cap (2) and part of the pin rod (1) need to be welded together with the needle wheel disc. In the welding area of ​​the pin cap (2) and part of the pin rod (1), leave a margin of more than 2 mm in the carburizing and quenching zone (3) on one side. The welding zone is covered by the carburizing and quenching zone (3), and the rest is used with a turning tool Turning; after carburizing and quenching treatment, use a turning tool to remove the excess unilateral 2mm of the carburizing and quenching zone (3); weld the pin cap (2) and part of the pin rod (1) of the cathode vibration needle pin ) is integrated with the dial.

Abstract

The invention discloses a machining technological method for a cathode vibrating and hitting pin wheel pin of an electric dust collector. The cathode vibrating and hitting pin wheel pin comprises a vibrating and hitting pin wheel pin body composed of a pin rod and a pin cap. The machining technological method is characterized in that a certain of unilateral margin is reserved on the pin cap and part of the pin rod in a welding area, and the rest of the pin rod is turned through a turning tool; after carburizing and quenching are conducted, the unilateral margin reserved on the pin cap and part of the pin rod is turned away through the turning tool; and the vibrating and hitting pin wheel pin body is welded to a pin wheel disc. The problem that that when a permeability-reducing agent is smeared on the pin wheel pin in the electric dust collector, smearing is not uniform is effectively solved, and the phenomenon that cracks are generated during welding due to carburizing and quenching of a head is avoided; it is well ensured that transmission vibrating and hitting of the electric dust collector are stable, and the dust collection effect is can be kept stable.

Description

technical field [0001] The invention belongs to the technical field of electric precipitators, and in particular relates to a processing method for cathode rapping pins of electric precipitators. Background technique [0002] The cathode rapping needle wheel of the electrostatic precipitator is an important transmission part inside the electric field. The pin wheel pin is a key part of the pin wheel. It must be wear-resistant, and its head and the pin wheel plate must be welded firmly. Car - apply anti-seepage agent to the head - carburizing - quenching - remove the anti-seepage agent - weld the head and the needle wheel. In actual production, due to uneven application of anti-seepage agent, it often causes cracks during welding due to carburizing and quenching of the head, which seriously affects the cathode rapping transmission of the dust collector and affects the dust removal effect. Therefore, it is necessary to rap the cathode of the electrostatic precipitator The whe...
