A self-draining vacuum filter

Abstract

The invention discloses an automatic drainage vacuum filter. The automatic drainage vacuum filter comprises a shell, an intake cavity arranged at the upper end of the shell, an intake pipe and an exhaust pipe arranged at two ends of the shell, a cutting liquid drainage cavity formed in the shell and connected with the intake cavity, a first one-way valve arranged at the upper end of the cutting liquid drainage cavity for draining cutting liquid, a second one-way valve arranged at the lower end of the cutting liquid drainage cavity for draining the cutting liquid, a drainage valve element connected with the intake cavity and the cutting liquid drainage cavity, a sealing device arranged on the outer side of the drainage valve element, and a driving device arranged at the lower end of the shell; the drainage valve element is a hollow pipe with closed lower end and opened upper end; and two laps of first drainage holes and second drainage holes are formed in the side wall of the drainage valve element in sequence from top to bottom. Through the design, the cutting liquid in the vacuum filter can be quickly drained, so that the device can continuously and normally work.
