Embodiment Construction

[0029] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] The invention provides a hydraulic oil filtering device, which is mainly used for filtering the hydraulic oil in the hydraulic system of the forklift, so that the hydraulic oil of the forklift can be used repeatedly, which greatly saves the production cost.

[0031] like figure 1 As shown, the filtering device includes a dirty oil tank 100, an oil filter tank 200 and a clean oil tank 300 which are arranged side by side in sequence, wherein an oil suction machine 110 is arranged on one side of the dirty oil tank 100, here is the oil suction station, and the forklift 500 is driving To the oil suction station, the dirty hydraulic oil in the hydraulic oil tank of the forklift can be sucked out by the oil suction machine and transported to the dirty oil tank. One side of the clean oil tank 300 is provided with a refueling machine 310, whic...

Abstract

The invention provides a device for filtering hydraulic oil of a forklift. The device comprises a slop oil tank, an oil filtering tank, an oil purifying tank, an oil sucking machine, an oil feeding machine and an oil filtering machine unit. The invention also provides a method for filtering the hydraulic oil of the forklift by using the device. The method comprises the following steps of controlling the forklift to run to an oil sucking workstation; enabling a portal of the forklift to ascend, descend and obliquely move in the front-back direction repeatedly; starting the oil sucking machine to suck oil of a hydraulic oil tank of the forklift; sucking the hydraulic oil of the forklift in the slop oil tank; filtering the hydraulic oil of the forklift in the slop oil tank by using a second oil filtering machine and conveying the filtered hydraulic oil to the oil filtering tank; filtering the oil by using a first oil filtering machine and then conveying the oil to the oil purifying tank; running the forklift to an oil feeding workstation after oil suction operation is finished; feeding oil in the hydraulic oil tank of the forklift by using the oil feeding machine; and feeding the filtered hydraulic oil in the oil purifying tank in the hydraulic oil tank of the forklift. The device has the advantages that the filtering time is short, the filtering effect is high, oil suction operation and oil feeding operation can be simultaneously performed on two forklifts, filtering operation can be continuously performed without waiting when the filtering amount is large, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of filtering, in particular to a filtering device and a filtering method for forklift hydraulic oil. [0002] Background technique [0003] As a mobile and flexible means of transportation, forklifts play an increasingly important role in cargo transportation and storage places such as ports, railways, warehouses, and freight yards. The quality of its hydraulic system directly affects the performance and efficiency of forklifts. . According to relevant statistics, hydraulic system failures account for 54% of the total failures of forklifts, and more than 75% of hydraulic system failures are related to the pollution of the hydraulic system, so it is particularly important to control the pollution of the forklift hydraulic system. [0004] The pollution sources of the forklift hydraulic system mainly include solid particle pollutants. The reasons for the output of solid particle pollutants include the follo...
