Abstract

The invention discloses a synchronous planet-tracking liquid spraying and negative-pressure gas absorption device. The synchronous planet-tracking liquid spraying and negative-pressure gas absorption device comprises an integrated liquid spraying and gas absorption head and a gas recovery device, wherein a middle liquid spraying connection head is arranged on a fixing frame; a liquid spraying pipe is connected with the middle liquid spraying connection head; a liquid spraying and gas absorption nozzle is arranged at the front end of the middle liquid spraying connection head; a horn-shaped gas scraping cover is arranged at the front end of the liquid spraying and gas absorption nozzle; gas holes are circumferentially and uniformly formed in the liquid spraying and gas absorption nozzle and are communicated with a circular channel; one end of a gas absorption pipe is connected to the middle liquid spraying connection head through a middle connection head; a negative-pressure pipe hole channel which is communicated with the circular channel is arranged in the gas absorption pipe; the other end of the gas absorption pipe extends into a part below the liquid level in an alkali solution box through a negative-pressure gas absorption pump. According to the device, NO2, CO and H2 generated in the electrolysis process of efficient synchronous liquid spraying and negative-pressure gas absorption are electrolyzed, ground and polished through a hard alloy material, and sediments are effectively separated and electrolyzed, so that electrolysis, grinding and polishing equipment is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of green and environment-friendly electrolytic grinding processing, in particular to a planet tracking liquid spraying synchronous negative pressure absorbing gas and sediment circulation processing device. Background technique [0002] At present, hard alloy materials are used to manufacture narrow curved surface molds, and manual grinders after EDM are generally used to drive diamond grinding heads for grinding and polishing. Due to the narrow space, the processing is difficult, and the manufacturing accuracy is low, the surface roughness value is large, and the consistency is poor. The request cannot be met. [0003] There is no cutting force in electrolytic machining, and there is no residue and deformation on the processed surface. Using the principle of electrolysis, the surface of the mold is sprayed with acid, the negative pole of the power supply is connected to the grinding head, and the positive p...

Problems solved by technology

[0004] Electrolytic grinding and polishing of curved surfaces has a good application prospect in mold manufacturing, but there is also a major difficulty that needs to be broken through. The electrolytic processing of cemented carbide has CO, NO 2 、H 2 Gas removal, NO 2 Pollution to the environment has always limited the application of electrolytic processing. It must be green and "zero" emissions, and the exhaust gas needs to be effectively treated. The solution is to spray acid as effectively as possible to reduce the amount of gas generated and negative pressure suction. And processing, forming a virtuous circle of reuse
