Abstract
The utility model relates to a steel-making blast furnace hydraulic-oil system which is provided with a system of circulating filtering and an oil-feeding pump. The utility model comprises a main hydraulic-oil system (1), wherein the main hydraulic-oil system comprises a main oil tank (1.3). The utility model is characterized in that a set of complementary circulating filtering and oil-feeding system (2) is installed additionally beside the main hydraulic-oil system (1), the supplementary circulating filtering and oil-feeding system (2) comprises a switching valve (2.1), a filter I (2.2), an oil pump (2.3) and a filter II (2.4), wherein an oil inlet of the switching valve (2.1) is communicated respectively with the main oil tank (1.3) and a reserve oil tank, an oil outlet of the switching valve (2.1) is communicated with an inlet of the filter I (2.2), an outlet of the filter I (2.2) is communicated with the inlet of the oil pump (2.3), the outlet of the oil pump (2.3) is communicated with the inlet of the filter II (2.4), and the outlet of the filter II (2.4) is communicated with the main oil tank (1.3). The utility model can complement hydraulic-oil in comparatively short time, and thereby the production continuity can be guaranteed.
Description
Technical field
The utility model relates to a kind of blast furnace hydraulic oil system, especially relates to a kind of steel-making blast furnace hydraulic oil system that has replenishment cycles filtration, oil feeding system.Belong to the metal smelt technical field.
Background technique
Hydraulic oil system medium---hydraulic oil is the necessary carrier that transmits hydraulic power, and hydraulic system has lost hydraulic oil and also just lost power, and this system is just paralysis thereupon also.As: steelmaking furnace furnace roof hydraulic system is because of the high-pressure rubber pipe explosion, fuel tank hydraulic oil is exposed to light accidentally and causes blast furnace staying a period of time, bring very big influence to furnace processor like this, also influenced the tar ratio of blast furnace greatly, the ordinary production of later process steel-making, steel rolling is all had considerable influence.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can supply hydraulic oil within a short period of time, guarantees to produce unbroken steel-making blast furnace hydraulic oil system that has replenishment cycles filtration, oil feeding system.
The purpose of this utility model is achieved in that a kind of replenishment cycles filtration that has, the steel-making blast furnace hydraulic oil system of oil feeding system, comprise main hydraulic oil system, described main hydraulic oil system comprises main fuel tank, it is characterized in that: other the increasing of described main hydraulic oil system is equipped with a cover replenishment cycles filtration, oil feeding system, this replenishment cycles is filtered, oil feeding system comprises switching valve, filter I, oil pump and filter II, described switching valve filler opening is connected with main fuel tank and fuel reserve tank respectively, the switching valve oil outlet is connected with filter I import, filter I outlet is connected with the oil pump import, the oil pump outlet is connected with filter II import, and filter II outlet is connected with main fuel tank.
The utility model increases a cover replenishment cycles filtration, the oil feed pump system of adorning by the main hydraulic oil system side at steel-making blast furnace, when even main hydraulic system loses hydraulic oil, also can replenish enough hydraulic oil by replenishment cycles filtration, oil feed pump system, guarantee to produce and do not interrupt in the short period.And can make fluid clean, can prolong the working life of hydraulic element more by the regular circulating filtration hydraulic oil of conversion switching valve energy, guarantee the work of hydraulic oil system.
