Abstract

The invention provides a piston-type filtering device. The piston-type filtering device comprises a thrust device and a thrust ring device, wherein the thrust device is correspondingly arranged on one side of the thrust ring device, and the surface of the thrust device and the surface of the thrust ring device are in matched contact; a filtering device is clamped between the thrust device and the thrust ring device; a feeding channel is arranged in the thrust device; a piston block is arranged in the thrust ring device and can slide and extrude in the thrust ring device; a seal ring is arranged between the thrust ring device and the piston block; a pressing device is arranged on the outer side of the thrust ring device and presses the piston block in the thrust ring device. The piston-type filtering device has the advantages that the design is reasonable, the structure is simple, large-area extrusion and efficient filtering can be realized, a filtering medium is recovered in a centralized manner, the internal structure is stable and the service life is long.

Description

[0001] technical field [0002] The present invention relates to the field of filtering devices, more specifically, to a piston type filtering device. Background technique [0003] Filtration; [iltr;iltrt] The process of purifying fluid through special devices. There are many methods of filtration, and a wide range of material systems are used. Solid-liquid, solid-gas, large particles, and small particles are all common. Under the action of driving force or other external force, the liquid or gas in the suspension or the heating gas containing solid particles penetrates the medium, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances are separated from the liquid or gas. [0004] In the prior art, there are also many filtering devices, and the multi-media filter is also called a mechanical impurity filter, which is one of the main equipment for water quality pretreatment. According to the water quality, the c...
