AI Technical Summary
Technical Problem
Existing oil filters used in chemical production are prone to clogging at the filter screen, requiring frequent cleaning or replacement, resulting in poor filtration performance.
Method used
It adopts a dual-filter design, with a fine filter and a coarse filter installed separately. The filtration is achieved from bottom to top through the cooperation of a cylinder and a connecting rod. Impurities are left below the filter screen to avoid clogging, thus achieving two-stage filtration.
Benefits of technology
It effectively avoids filter clogging, ensures continuous and efficient operation of the oil filter, removes impurities more thoroughly, and extends the service life of the equipment.

Abstract
This utility model discloses an oil filter for chemical production, comprising two filter canisters. A fine filter screen and a coarse filter screen are fixedly installed in the inner cavity of each filter canister. A piston is movably connected to the lower part of the inner cavity of each filter canister. A cylinder is installed through the top of each filter canister, and a connecting rod is fixedly installed at the movable end of the cylinder. Both the fine and coarse filter screens have insertion holes corresponding to the connecting rod, which is inserted into these holes. A liquid injection valve is connected to the lower side wall of the filter canister corresponding to the coarse filter screen, and a liquid drain valve is connected to the upper side wall of the filter canister corresponding to the fine filter screen. A lower ventilation hole is provided at the bottom of each filter canister. A connecting pipe is provided between the two filter canisters. The input end of the connecting pipe is connected to the upper side wall of the filter canister corresponding to the coarse filter screen, and the output end of the connecting pipe is connected to the lower side wall of the filter canister corresponding to the fine filter screen. This utility model relates to the technical field of oil filters. This oil filter filters oil from bottom to top, preventing oil residue from remaining on the fine and coarse filter screens and avoiding the problem of frequent cleaning or replacement due to filter screen clogging.
