Abstract

The invention discloses a telescopic filter which consists of a plurality of telescopic stages, and comprises a first stage of filter, a second stage of filter and a third stage of filter; a three-stage filtering way is formed by net type filter cores, paper filter cores and magnetic bars which are respectively arranged in the multiple stages of filters; internal hydraulic oil entering the filters or an external hydraulic oil source is adopted to control the extension of the stages of filters; the stages of filters can slide in a cylinder barrel between a shell of the first stage of filter and a welding steel cylinder, so that the filter cores of the filters can fully stretch for filtering; the filters can filter in the manner that hydraulic oil enters the filters through an oil hole of a one-way valve, and then the stretching filter cores are used for fully filtering. The pressure alarm and signal transmission can be carried out by a pressure relay of the system. When outlets of the filters are blocked and the filter cores need to be replaced, the stages of filters can retract into a first stage of cylinder barrel by virtue of the external hydraulic oil source so as to be disassembled. The filter is compact in structure, good in effect of three-stage filtering, simple to install and convenient to disassemble.

Description

technical field [0001] The invention relates to a filter, in particular to a telescopic filter. Background technique [0002] Common filters in engineering can be divided into integral filters and split filters according to different structural forms. Integral filters, their advantages are simple structure, easy overall installation and disassembly; the disadvantage is that in order to meet the filtering accuracy, the volume is relatively large, and the relative installation space is relatively large. Because in general, the filter satisfies the filtration accuracy by increasing the length of the filter element in the filter, and the filter element should be installed in the filter as a whole, so the volume of the filter will be large. [0003] The principle of the split filter is to put the second part into the filter, install it on the hydraulic circuit, install the first part on top of the second part, and then connect the two parts with bolts. This connection method is...
