Filtering device for particle oil in printing and dyeing aqueous liquid

Abstract

The invention discloses a filtering device for particle oil in printing and dyeing aqueous liquid. The filtering device comprises a filtering tank and an oil removal filtering tank; the filtering tank comprises a left filtering tank part and a right filtering tank part; a bottom plate of the right filtering tank part is lower than a bottom plate of the left filtering tank part; the upper part of the filtering tank is fixedly provided with an upper plate body; the upper part, located at the left filtering tank part, of the upper plate body communicates with a liquid inlet pipe; the bottom plate of the left filtering tank part communicates with a particle discharge pipe; the bottom end of the particle discharge pipe is fixedly provided with a plug; the lower part of the right end face of the right filtering tank part communicates with a liquid outlet pipe; the lower part of a left side plate of the oil removal filtering tank communicates with an oil removal liquid inlet pipe; the oil removal liquid inlet pipe communicates with a liquid outlet pipe; the top face of the left side plate of the oil removal filtering tank is fixedly provided with an oil removal support plate; the top face of an upper partition plate is fixedly provided with an upper oil removal support plate. As multiple filtering is adopted, the filtering device has a good filtering effect; moreover, the filtering device can automatically accumulate and remove the oil in waste water without manual fishing out, and has a good oil removal effect.

Description

Technical field: [0001] The invention relates to the technical field of printing and dyeing environmental protection equipment, in particular to a printing and dyeing water particle oil filter device. Background technique: [0002] The existing printing and dyeing sewage particle filtration method generally uses an intermediate filter screen to filter the particulate matter in the sewage. However, the existing filter screen is generally fixed on the frame frame, and the screen plate They cannot be replaced individually, but can only be replaced collectively, which is very troublesome and the existing filter devices generally perform single-time filtration, and the effect is not ideal. [0003] However, the existing printing and dyeing sewage degreasing and filtering method generally adopts the principle that an upper partition and a lower partition are arranged in the box, and the oil floats on the water surface through the flow of water, so that the water at the bottom flow...

[0002] The existing printing and dyeing sewage particle filtration method generally uses an intermediate filter screen to filter the particulate matter in the sewage. However, the existing filter screen is generally fixed on the frame frame, and the screen plate It cannot be replaced individually, but can only be replaced collectively, which is very troublesome and the existing filter devices generally only filter once, and the effect is not ideal

[0003] However, the existing printing and dyeing sewage degreasing and filtering method generally adopts the principle that an upper partition and a lower partition are arranged in the box, and the oil floats on the water surface through the flow of water, so that the water at the bottom flows, and the upper part The oil is blocked by the upper partition to remove the oil, and then the oil floating on the water is manually removed, the effect is not ideal, and the degree of automation is poor
