Iron scrap filter bed

Abstract

The invention discloses an iron scrap filter bed, which comprises a mesh surface filter bed, wherein filter paper is put on the surface of the filter bed; one end of the filter bed is provided with a water squeezing roller and an electromagnetic roller which are arranged in parallel, are in extrusion contact and are in reverse rotation; the water squeezing roller is arranged on a liquid outlet side of a liquid tank above the filter bed; the electromagnetic roller is provided with a scraper on the side away from the water squeezing roller; a scraper edge is abutted against the electromagnetic roller; the scraper is downwardly and obliquely arranged; both the water squeezing roller and the electromagnetic roller are connected with a motor through a belt conveying device; the water squeezing roller rotates clockwise; the inner surface of the electromagnetic roller is provided with an electromagnet; the electromagnet is connected with the motor; the surface of the water squeezing roller is provided with plush fabric; a tail liquid inlet pipe is arranged on the side wall of the liquid tank; a liquid convergence tank is arranged below the filter bed; and a liquid discharge pipeline is arranged on the bottom surface of the liquid convergence tank. According to the iron scrap filter bed, iron scraps can be continuously and automatically recovered, and the collection efficiency is high.

Description

technical field [0001] The invention relates to an iron filings filter bed, which is a device for collecting iron filings in lathe coolant, and belongs to the field of machinery. Background technique [0002] When the lathe is turning iron objects, the lathe drill bit rubs against the object being turned, rotating at high speed, the surface generates heat quickly, and the temperature is high. Drenched over the friction surface of the lathe drill bit and the object being turned, to cool down and wash away the iron filings. After the coolant drips from the lathe drill bit, it is called tail liquid, and iron filings are mixed in the tail liquid. The iron filings in the tail liquid should be recovered, otherwise it will cause waste of resources and environmental pollution. The traditional method of recovering iron filings in the liquid is to use magnetite to absorb or filter. The magnetite adsorption should regularly remove the iron filings on the surface of the magnetite, whi...

The iron filings in the tail liquid should be recycled, otherwise it will cause waste of resources and environmental pollution

The traditional method of recovering iron filings in the liquid is to use magnetite to absorb or filter. The iron filings on the surface of the magnetite should be removed regularly for magnetite adsorption, which is not conducive to continuous operation. The iron filings in the tail liquid are filtered and recovered, and the recovery efficiency is low.
