Specifically, absolute oil case 300 provides clean machine oil for roller mill, for example, the absolute oil case 300 is additionally provided with oil transportation Mouth (not shown), the oil transportation mouth by a petroleum pipeline with the spray tube of roller mill for being connected, in this way, absolute oil case 300 passes through Oil transportation mouth and petroleum pipeline convey clean machine oil to spray tube so that roller mill being capable of continuous firing.

Machine oil is on roller mill after use, with being filtered in oil delivery to the filtering tank 200 of impurity, specifically, Machine oil with impurity is delivered to screen pipe 230 by oil return pipe, and screen pipe 230 is by the oil injection with impurity to filtration core On 221, filtration core 221 is filtered impurity, and then the machine oil after filtering will be delivered to absolute oil case 300 and preserve, and is roll Machine provides clean machine oil.

After prolonged use, when the amount of impurities that filtration core 221 adheres in filtering tank 200 is more, compressed gas is passed through Tank 400 to 230 jet of screen pipe, high-speed gas that the spray orifice 233 of screen pipe 230 sprays by the impurity landing on filtration core 221, Then, absolute oil case 300 conveys machine oil to filtering tank 200, washes away the impurity of landing by machine oil, realizes to filtration core 221 Anti- cleaning.

By the 3rd pipeline 730 by the oil delivery after washing away to settling tank 500, settling tank 500 will carry filtering tank 200 The machine oil of impurity carries out precipitation filtering so that the impurity in machine oil obtains precipitation filtering, and eliminates the dirty oil of impurity then again Filtering tank 200 is back to by dirty fuel tank 600 to be cycled, it is achieved thereby that machine oil recycles, effectively removes system 10 In impurity, be conducive to the stable operation of roller mill, improve roll-in quality.For example, the 5th pipeline 750 is connected with screen pipe 230, It is filtered in this way, the machine oil in dirty fuel tank 600 can be entered by the 5th pipeline 750 and screen pipe 230 in filtering tank 200.

Specifically, since the density ratio machine oil of impurity is high, impurity is easily deposited in the bottom of settling tank 500, and by It is set in the bottom of settling tank 500 by several partition plates 510, and partition plate 510 and the side wall of settling tank 500 are tightly connected so that After contamination precipitation, it will be isolated by partition plate 510, and since the height of partition plate 510 is less than the height at the top of settling tank 500, That is, partition plate 510 is raised in height of the height less than the side wall of settling tank 500 of 500 bottom of settling tank, therefore, precipitation The machine oil on 500 upper strata of case is then machine oil free from foreign meter, after the contamination precipitation of machine oil, you can by the machine on 500 upper strata of settling tank Oil is delivered to dirty fuel tank 600, and is delivered to filtering tank 200 by dirty fuel tank 600, and dirty oil is filtered again, and after filtering Machine oil will be delivered to absolute oil case 300 and store, so as to complete the cycling of machine oil, effectively reduce in the circulatory system 10 Impurity content.

In order to further improve deposition efficiency, in one embodiment, as shown in Fig. 2, by each inside the settling tank 500 The partition plate 510 is isolated into several precipitation chambers 501, for example, for example, the width of the precipitation chamber 501 is by close to the settling tank One end of the one end at 500 top to the bottom close to the settling tank 500 is gradually reduced.For example, the precipitation chamber 501 is cut Face is trapezoidal.In this way, since the width at the top of precipitation chamber 501 is larger, be conducive to increase the desilting area of the machine oil on upper strata, energy Enough so that impurity fully precipitates, and since the width of the bottom of precipitation chamber 501 is smaller so that contamination precipitation to precipitation chamber 501 Behind bottom, it is not easy to be influenced be subject to the machine oil on upper strata, so that sedimentation effect is more preferably.

In order to enable the machine oil with impurity after washing away can fully be emitted into settling tank 500, for example, such as Fig. 1 and Fig. 2 Shown, the 3rd pipeline 730 is communicated in filtering tank 200 close to the position of bottom, in this way, the machine oil after washing away will drop to filtering tank Bottom in 200, so as to be delivered to by the 3rd pipeline 730 in settling tank 500, and impurity is easily in settling tank 500 Bottom is isolated by partition plate 510, avoids with engine oil flow.

In order to avoid the machine oil containing impurity is transported to dirty fuel tank 600, for example, incorporated by reference to Fig. 1 and Fig. 2, the described 4th Pipeline 740 is communicated in the settling tank 500 close to the position at the top of the settling tank 500.It should be understood that precipitation is miscellaneous After matter is sunk to the bottom, the machine oil on upper strata contains that impurity is less or free from foreign meter, and therefore, the 4th pipeline 740 can be first by settling tank The oil delivery on the upper strata in 500 effectively avoids impurity from being transported to dirty fuel tank 600 to dirty fuel tank 600.

In order to improve the jet pressure of the machine oil of the spray orifice 233 of screen pipe 230 so that machine oil can be fully sprayed to filtering It is fully filtered in core 221, for example, the internal diameter of the screen pipe 230 is less than the internal diameter of the second pipe 720.Due to The internal diameter of two pipelines 720 is larger, can to the machine oil that screen pipe 230 conveys flow it is larger, and due to the internal diameter of screen pipe 230 It is smaller so that pressure of the machine oil of larger flow in screen pipe 230 is larger so that spray orifice 233 can at a high speed spray machine oil Be incident upon filtration core 221 so that machine oil can fully penetrated filtration core 221 so that machine oil can be filtered fully.

In order to improve the jet pressure of the gas of the spray orifice 233 of screen pipe 230, so that the impurity on filtration core 221 It can be by abundant landing, for example, the internal diameter of the screen pipe 230 is less than the internal diameter of the appendix 760.Due to appendix 760 Internal diameter it is larger, and the internal diameter of screen pipe 230 is smaller so that larger flow is in the smaller screen pipe 230 of internal diameter in appendix 760 It is interior to generate larger pressure, so that gas can be sprayed from 233 high speed of spray orifice of screen pipe 230, so that filtration core 221 can fully be sprayed, so that the impurity on filtration core 221 can be by abundant landing so that the cleaning of filtration core 221 It is better.

In order to enable the impurity of settling tank 500 can be eliminated, for example, as shown in Fig. 2, the top of the settling tank 500 It opens up by case mouth 502, for example, being additionally provided with case lid 520 on the settling tank 500, the case lid 520 is connected to the settling tank The edge of 500 opening, and the case lid 520 closes the case mouth 502.In this way, when the contamination precipitation in settling tank 500 compared with When more, impurity can be removed by case mouth 502 by opening case lid 520.In order to remove impurity, for example, solenoid valve control Three pipelines 730 are closed, and another the 4th pipeline 740 of electronic valve Confucius is opened, by the 4th pipeline 740 by the machine in settling tank 500 Oil is expelled to dirty fuel tank 600, and the closing of the 3rd pipeline 730, can be delivered to settling tank 500 again to avoid machine oil, work as precipitation After machine oil liquid level in case 500 declines, be conducive to clear up the impurity of 500 bottom of settling tank.

In order to enable the impurity in settling tank 500 is fully precipitated, for example, the bottom of the precipitation chamber 501 set by Several adsorption layers, for example, the material of each adsorption layer is activated carbon, for example, each adsorption layer is active carbon layer, the activity Layer of charcoal being capable of adsorbing contaminant, and can speed up contamination precipitation well so that the impurity in settling tank 500 is fully sunk It forms sediment, further, since impurity, which can be concentrated, is precipitated to adsorption layer so that impurity is convenient to clean.

In order to fix each adsorption layer, and each adsorption layer is easily withdrawn, for example, the precipitation chamber 501 is also set up There is link, each adsorption layer is respectively arranged on the link.For example, each adsorption layer is cascadingly set on institute It states on link, for example, the link includes supporting rack and several carriers, several carriers are arranged at intervals successively, And it is connected respectively at support frame as described above, for example, each carrier is welded with support frame as described above, for example, each adsorption layer It is separately positioned on the carrier, for example, each adsorption layer is arranged on a carrier.

In order to further improve contamination precipitation efficiency, for example, the bottom of the settling tank 500 is provided with magnetic part, example Such as, the bottom of the settling tank 500 is provided with magnetic part on one side backwards to the precipitation chamber 501, the magnetic part for adsorb iron, The impurity such as nickel, it should be understood that steel disc, containing impurity such as iron, nickel in the chip that equipment drops, passes through magnetic during roll Property part can speed up these contamination precipitations, and be not easy to float again after causing these contamination precipitations, so that precipitation effect Fruit is more preferably.

In order to enable iron, nickel move magnetic part when impurity can be quickly removed out of settling tank 500, it is necessary to remove Go out, for example, the material of the settling tank 500 is plastic cement, for example, the settling tank 500 is plastic box, such as the settling tank 500 bottom is set backwards to the one side of the precipitation chamber 501 there are two guide rail, and two opposite one sides of guide rail offer respectively Sliding groove, the magnetic part are slideably positioned in respectively in two sliding grooves, in this way, when needing to remove iron, nickel when impurity, It only needs to skid off magnetic part along sliding groove, and since settling tank 500 is plastic cement material, it can't be to the cunning of magnetic part Dynamic to impact, after magnetic part skids off, the impurity such as iron, nickel can be eliminated easily.
