The filter equipment in the prior art is to filter the dirty oil discharged from the processing machine through the filter element of the filter equipment, and at the same time send the clean oil to the nozzle of the processing machine. Before cleaning the slag, the compressed air first discharges the dirty oil in the filter equipment, and then the compressed air discharges the waste slag attached to the periphery of the filter element and sends it to the waste bag. The whole process takes a long time. When the waste in the waste bag accumulates After reaching a certain level, clean up in time

Embodiment
[0022] Such as figure 1 As shown, a filtering device includes a dirty oil tank 1, a clean oil tank 2, and a compressed air delivery pipeline. A pressure tank 3 is arranged in the dirty oil tank 1, and a filter element is arranged inside the pressure tank 3 (because it is installed inside, so not shown in the figure); the top of the pressure tank 3 is provided with a clean oil delivery pipe 31, and the bottom of the pressure tank 3 is provided with an oil discharge pipe 32, and the clean oil delivery pipe 31 communicates with the clean oil tank 2; The oil pipe 32 is connected to the slag scraper 5, and the oil discharge pipe 32 is provided with a control valve 6; the middle part of the pressure tank 3 is provided with a dirty oil delivery pipe 11, and the dirty oil delivery pipe 11 is connected with a filter pump 12; Described compressed air pipeline comprises compressed air main pipeline 41, first compressed air branch pipeline 42 and second compressed air branch pipeline 43, ...

The invention discloses a filter device. The filter device comprises a dirty oil tank, a clean oil tank and a compressed air conveying pipeline, wherein a pressure tank is arranged in the dirty oil tank, and a filter element is arranged in the pressure tank. The invention also discloses a filtering process of the filter device. When the filter device is operated continuously for a long time, and before the back-flushing slag removing is performed, the compressed air conveying pipeline is arranged to make dirty oil in the filter device be filtered by upward extrusion of the filter element, therefore, a part of dirty oil in the pressure tank is changed into clean oil; and then, compressed air passes through the top part and the center of the filter element to make waste slag attached around the filter element and residual dirty oil be discharged and treated. The filter device is simple in structure, and the whole process is finished by a PLC (Programmable Logic Controller) without machine halt, the time of whole process of draining dirty oil and back-flushing slag removing is not more than 5 minutes, the working efficiency is improved, and the time and labor are saved.
Description
technical field [0001] The invention relates to the technical field of filtration, in particular to a filtration device and a filtration process thereof. Background technique [0002] In the process of industrial processing, cutting oil, lubricating oil, cooling oil and other oils are often used, and the chips and other dirt of the processed materials are easy to fall into the oil, so that the oil must be filtered before it can be reused. The filter equipment in the prior art is to filter the dirty oil discharged from the processing machine through the filter element of the filter equipment, and at the same time send the clean oil to the nozzle of the processing machine. Before cleaning the slag, the compressed air first discharges the dirty oil in the filter equipment, and then the compressed air discharges the waste slag attached to the periphery of the filter element and sends it to the waste bag. The whole process takes a long time. When the waste in the waste bag accumu...
