in more detail:

1. referring to fig. 1, a storage tank filled with lubricating oil (with an opening at the top thereof in advance) is placed in a storage cavity in a preheating cylinder, and a supporting platform is driven to descend by a cylinder driver until an oil inlet pipe penetrates into the storage tank from the top thereof (and the telescopic damping part is stopped from contacting with the top of the storage tank), on the basis, the lubricating oil in the storage tank is extracted by operating an oil pump, and the extracted lubricating oil is sent into a filtering assembly through an oil outlet pipe (namely, sent into the filtering cylinder body for filtering);

2. referring to fig. 1 to 5, the lubricant entering the filter cartridge is filtered by the internal filter body disposed in the filter cartridge (i.e., the lubricant entering the filter cartridge directly contacts the internal filter body and is primarily filtered by the primary filter holes disposed on the surface of the internal filter body), because of the arrangement of the internal filter body (i.e., the inclined arrangement of the top thereof), when impurities are larger than the pore diameter of the primary filter holes, the impurities are isolated between the internal filter body and the internal filter body, and the primarily filtered lubricant flows to the bottom of the filter cartridge and is discharged from the secondary oil outlet pipe; it should be noted that: when certain impurities are accumulated between the inner filter body and the filter cylinder body, the cylinder cover can be opened to clean the inside of the cylinder cover;

3. referring to fig. 1 to 5 and fig. 6, the secondary oil outlet pipe sends the primarily filtered lubricating oil into the filter tank body for secondary filtering, because filter mesh layers (for example, 4 filter mesh layers) are arranged in the filter tank body at intervals from the filtering direction thereof, and the secondary filter holes on each filter mesh layer are gradually reduced from the filtering direction of the lubricating oil, so that impurities in the lubricating oil can be gradually filtered (meanwhile, the filter tank body can be periodically treated or replaced), the lubricating oil after multistage filtering of the filter mesh layers flows to the oil outlet, and the oil discharge module arranged at the oil outlet is used for accelerating the discharging efficiency of the lubricating oil, so that the filtering efficiency of the lubricating oil can be improved, which is mainly embodied as follows: rotate through motor drive oil drainage axle, and then drive and arrange oil board subtend of oil shaft outer wall fixed connection and arrange the lubricating oil that the oil assembly flows and carry out "dispersion", promptly: the lubricating oil is guided to the circumferential inner side wall of the filtering tank body, and the oil outlet is formed in the circumferential inner side wall, so that the discharging efficiency of the lubricating oil can be improved, and the filtering efficiency of the lubricating oil is improved; secondly, due to the multi-stage filtering effect in the filtering tank body, the filtering effect on the lubricating oil can be further improved;

it needs to be further explained that:

firstly, when the lubricating oil in the storage tank is condensed (even solidified), part of water can be added into the preheating cylinder, and the electromagnetic heater arranged in the lower chamber heats the water in the upper chamber through the sealing plate, so that the lubricating oil in the storage tank is heated, the phenomenon of condensation of the lubricating oil in the storage tank can be effectively eliminated (or partially eliminated), and the oil pumping effect of the oil pump is ensured;

secondly, the hot water in the upper chamber can be stirred at the diversion subassembly that supports base below (preheating cylinder top) setting, promptly: the motor drives the first belt pulley and the second belt pulley to rotate, so that the second belt pulley drives the flow guide block fixedly connected with the connecting shaft to rotate, hot water in the upper chamber starts to flow, the heat transfer efficiency between the hot water and the storage tank can be improved, and the efficiency of eliminating the condensation of lubricating oil is improved; secondly, the guide block arranged on the guide plate (and the section diameter of the guide block is 2 times of the thickness of the guide plate) can improve the contact area with hot water, so that the amount of hot water stirred in unit time is increased, and the heat transfer efficiency and the heat transfer effect between the hot water and the storage tank are improved;

thirdly, when the phenomenon of 'condensation' of the lubricating oil in the storage tank is eliminated (or after partial elimination), a valve on the drain pipe is opened to drain the hot water in the preheating cylinder, if the oil pumping efficiency of the oil pump is reduced (the phenomenon can be realized by discharging oil from the tail end or arranging a flow meter on the oil pump), on the premise of ensuring that the storage tank is not damaged, the hydraulic cylinder can be driven firstly to extrude the storage tank by matching the first extrusion block and the second extrusion block which are positioned at the bottom of the upper chamber (refer to figures 3-4), it can "move" the lubricant oil located at the bottom of the tank partially towards the top (due to the reduced volume at the bottom of the tank), so that with the oil pump stationary, lubricating oil can be smoothly pumped from the oil inlet pipe, and the extrusion modules are sequentially controlled by the same method (in order to prevent the extrusion modules from contacting with the flow guide block, the horizontal height of the flow guide block can be higher than that of the uppermost extrusion module); secondly, the horizontal extrusion part on the second extrusion block is in a cylindrical shape, and when the storage tank is extruded, the extrusion effect can be effectively improved (compared with the case that the extrusion surface is a horizontal plane, the extrusion surface of the horizontal extrusion part is in a linear shape, so that the stress area is reduced, and the stress effect can be improved);

fourthly, in order to guarantee the stability of the oil pump when extracting, the outer wall of the oil inlet pipe is provided with a telescopic damping part, and the principle is as follows: if the storage tank shakes during extraction, vibration force generated by shaking (or vibration) of the storage tank is transferred to the compression spring through the inner shaft due to the fact that the locating sleeve is in contact with the top of the storage tank, and then the vibration absorption state of the storage tank can be partially eliminated, and stability of the oil pump during extraction is improved;

fifthly, in order to avoid water in the preheating cylinder from flowing out, sealing rings (refer to fig. 4) are arranged on the first extrusion block and the second connecting part, so that the sealing effect of the movable part of the transmission shaft is improved, and hot water in the transmission shaft is prevented from flowing out;

sixth, the sunken setting of filtering barrel bottom can make things convenient for lubricating oil to remove to second grade oil outlet pipe department to also can effectual improvement oil extraction efficiency.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
