Detailed Description
As shown in figure 1, an oil inlet 1 is connected with an oil storage tank 4 through a pipeline, a heater 18 is arranged in the oil storage tank 4, an electronic liquid level sensor 16 is arranged on the oil storage tank 4, a partition plate 5 is arranged in the oil storage tank 4, a sewage pipeline is arranged at one side of the bottom of the oil storage tank 4 close to the oil inlet, and a sewage valve 19 is arranged on the sewage pipeline. The outlet of the oil storage tank 4 is connected with the primary strainer 8 through a pipeline, an oil pump 15 is connected to a pipeline between the oil storage tank 4 and the primary strainer 8, the primary strainer 8 is connected with a dehydration and degassing system through a pipeline, a bypass valve 9 is arranged on a bypass pipeline of the dehydration and degassing system, an oil inlet valve 26 is arranged on an oil pipeline of the dehydration and degassing system, and a first oil outlet valve 10 is arranged on an oil outlet pipeline of the dehydration and degassing system. The dehydration and degassing system is connected with a secondary fine filter 20 through a southward pipeline, the secondary fine filter 20 is connected with a tertiary ultra-fine filter 21 through a pipeline, and the tertiary ultra-fine filter 21 is connected with an oil outlet 23 and an oil inlet pipeline through a pipeline. Pressure gauges 6 are respectively arranged on the pipelines before and after the primary coarse filter 8, the secondary fine filter 20 and the tertiary ultra-fine filter 21. A temperature controller 7 is arranged on a pipeline between the oil storage tank 4 and the primary coarse filter 8. The dehydration and degassing system is connected with a water receiver 12, an isolation valve 13 is arranged on a pipeline between the water receiver 12 and the dehydration and degassing system, a second exhaust valve 14 is arranged on an exhaust pipeline of the water receiver 12, and a first blow-down valve 11 is arranged on a blow-down pipeline of the water receiver 12. The output pipeline of the three-stage ultra-fine filter 21 is provided with a sampling valve 22.
The middle partition board 5 in the oil storage tank 4 divides the oil tank into two areas, and after the rust-proof oil enters the oil tank, large granular slag is precipitated at one side of an oil inlet of the oil tank and flows into the oil tank in the outlet direction; the electronic liquid level sensor detects the liquid level of the oil tank and transmits signals to the system control system. The primary coarse filter is made of stainless steel mat-shaped net material, and can clean the filter core, and the filtering precision can be less than or equal to 80 mu m. The second-stage fine filter is made of stainless steel mat-shaped net material, and can clean the filter element, and the filtering precision can be less than or equal to 20 mu m. The three-stage superfinishing filter adopts stainless steel mat-shaped net and high polymer material, and the filtering precision can be less than or equal to 5 mu m. Dehydration and degassing system: removing water and gas in the oil and discharging the oil outside the system. Sampling valve: the oil sample after three stages of filtration was checked for eligibility. Temperature controller: the temperature of the oil in the pipeline is detected, and the temperature is fed back to the control system. And (3) a circulation valve: when the temperature fed back by the temperature controller is smaller than the lowest temperature set by the pipeline, the control system opens the circulating valve, and the system opens the recirculation mode. Oil tank heater and equipment pipeline keep warm: the temperature of the whole system is guaranteed to be the same as that of an original oiling machine oil tank, and the filter is guaranteed not to be blocked by wax in oil due to too low oil temperature. The pressure gauge detects the pressure of each section of the pipeline, so that whether each filter is blocked or not can be judged conveniently.
An oil inlet 1 of the independent anti-rust oil filtering system of the oiling machine is connected with an outlet of a circulating oil outlet filter of the oiling machine, and an outlet of the system is connected with an original oiling machine oil tank of the production line. Because the production line is not the actual oil drain and the oil drain is not very large, an oil storage tank 4 is added in the system, two sets of heaters 18 are arranged in the oil storage tank 4 to ensure the oil temperature in the oil tank, an electronic liquid level sensor 16 of the oil storage tank 4 monitors the liquid level height of the oil tank, and when the liquid level of the oil tank reaches the set height, the electronic liquid level sensor 16 feeds a signal back to a control system, and the system starts an oil pump 15 to pump the oil into a filtering system. Firstly, oil is subjected to primary coarse filtration, large-particle slag is filtered, the filtration precision is less than or equal to 80 mu m, and then water and gas in the oil are filtered and removed from the system through a dehydration and degassing system. The dehydrated and degassed oil passes through a secondary fine filter 20 to filter out medium and small particle residues with the filtering precision less than or equal to 20 mu m, then passes through a tertiary super fine filter 21 to filter out tiny particles with the filtering precision less than or equal to 5 mu m, and finally the filtered oil is pumped into an oil tank of the oiling machine of the production line. And if the filter element is blocked, the corresponding pressure is lower than a set value, the pressure gauge feeds a signal back to a control system, the system sends an alarm instruction, and an operator informs maintenance personnel of cleaning or replacing the filter element. Sampling valve in the system is convenient for quality inspection personnel regularly sample, inspects the quality of oil. The oil tank heater and the equipment pipeline in the system keep warm, so that the temperature of the whole independent system is the same as that of the original oil tank of the oiling machine, the wax component in the filtered oil is not reduced, the on-site direct use can be met, and the filter is not blocked by the wax in the oil due to the too low oil temperature. The control system adopts a closed loop design, and feeds back signals of all control points to control the safe and stable operation of the whole system.
