Gold-spraying dust absorption device for thin-film capacitor

Abstract

The invention discloses a gold-spraying dust absorption device for a thin-film capacitor. The gold-spraying dust absorption device comprises an input air-induced steel pipe, an induced draft fan, an output air-induced steel pipe, a plastic corrugated pipe and a plastic bucket, wherein the input air-induced steel pipe is connected with the induced draft fan; the induced draft fan is connected to the output air-induced steel pipe; the output air-induced steel pipe stretches to the outdoors by penetrating through a wall hole of a wall body, and is connected with one end of the plastic corrugated pipe; the other end of the plastic corrugated pipe is arranged inside the plastic bucket; the plastic bucket is filled with tap water; the other end of the plastic corrugated pipe is arranged under a water surface. According to the gold-spraying dust absorption device for the thin-film capacitor disclosed by the invention, gold-spraying dust is precipitated in the water inside the plastic bucket, so that zero release is reached, metal powder is fully recycled, the dust adsorption effect is good, the metal powder is conveniently recycled, and the device is simple in structure and less in power consumption.

Description

technical field [0001] The invention relates to the technical field of thin film capacitor manufacturing, in particular to a thin film capacitor gold-sprayed dust absorbing device. Background technique [0002] In the manufacturing process of film dielectric capacitors, gold spraying is a very critical production process. This process is to use arc or flame to melt the metal wire, and then use compressed air to spray it from the nozzle at high speed to the end surface of the capacitor core to form the metal electrode surface. A large amount of metal dust will be produced during the gold spraying process, which will affect environmental protection. The existing gold spraying dust treatment methods are as follows: 1. The bag-type dust removal is effective, but it consumes a lot of power and it is difficult to clean the bag. 2. Water spray dust removal, but it is not conducive to the recycling of metal powder, and the waste is too large. Contents of the invention [0003] T...

Problems solved by technology

A large amount of metal dust will be produced in the process of spraying gold, which will affect environmental protection. The existing treatment methods for spraying gold dust are as follows: 1. The effect of cloth bag dust removal is good, but the power consumption is large, and it is difficult to clean the bag.

2. Water spray dust removal, but it is not conducive to the recycling of metal powder, and the waste is too large
