Description

Technical Field

[0001] The present invention relates to the technical field of industrial oil treatment equipment, and specifically relates to a simplified industrial oil purification, separation and filtration machine. Background Art

[0002] Industrial lubricating oils have a wide range of applications, and there are also many types of base oils. For example: pure mineral oil, PAO poly-α-olefin synthetic oil, polyether synthetic oil, alkylbenzene oil, biodegradable ester oil. When they become a certain industrial lubricating oil, they cannot be mixed with each other. For example, after polyether synthetic oil is mixed with other industrial oils, its performance will be significantly reduced. With the rapid development of industry and the strengthening of environmental awareness, oil-water separation technology has received more attention. Oil-water separation belongs to the category of liquid-liquid separation. Different methods are used for liquid-liquid separation according to the different states of oil in water and different requirements for treatment effects.

[0003] At present, some small enterprises in the market cannot afford a complete set of industrial oil purification and separation equipment. Because there is a simplified type of industrial oil, and the simplified industrial oil purification, separation and filtration machine has a relatively small feeding hole due to its relatively small size, and the industrial oil is relatively viscous, resulting in a very slow feeding speed, greatly reducing its purification and filtration rate. Moreover, there are many impurities in the industrial oil, and even screws fall into it, often blocking the feeding hole. Therefore, in view of the above problems, a simplified industrial oil purification, separation and filtration machine is proposed. Summary of the Invention

The upper and lower end faces of the oil control plate 614 are provided with uniformly distributed ventilation holes, and the ventilation holes penetrate through the upper and lower end faces of the oil control plate 614. This setting ensures that oil droplets can drip into the connecting pipe 610. The right end face of the treatment device 6 is fixedly connected to the separator filter machine body 2. The front end face of the separator filter machine body 2 is fixedly connected to an oil outlet device 7. The oil outlet device 7 includes an oil outlet frame 701 and an oil outlet pipe 702. The rear end face of the oil outlet frame 701 is fixedly connected to the separator filter machine body 2. An oil outlet pipe 702 is fixedly connected above the interior of the oil outlet frame 701. The front end face of the oil outlet frame 701 is fixedly connected to a fixing plate 703. A limit telescopic rod 705 is fixedly connected to the inner side of the rear end face of the oil outlet frame 701. The front end face of the limit telescopic rod 705 is fixedly connected to a fixing frame 706. Telescopic springs 704 are provided on both the upper and lower sides of the limit telescopic rod 705. An oil storage bottle 707 is provided inside the fixing frame 706. A sliding plate 708 is fixedly connected to the front end face of the fixing frame 706. A top block 709 is fixedly connected to the front end face of the sliding plate 708. A guide plate 710 is slidably connected to the lower end face of the fixing frame 706. The guide plate 710 ensures that the fixing frame 706 slides stably left and right when sliding. The lower end face of the oil outlet frame 701 is fixedly connected to the guide plate 710. A rotating plate 711 is rotatably connected to the front end face of the fixing plate 703. The front end face of the sliding plate 708 is flush with the front end face of the fixing plate 703.

One end of each telescopic spring 704 is fixedly connected to the oil outlet frame 701, and the other end of each telescopic spring 704 is fixedly connected to the fixing frame 706. A chute is provided on the lower end face of the fixing frame 706, and the fixing frame 706 is slidably connected to the guide plate 710 through the chute. The setting of the telescopic spring 704 ensures that the oil storage bottle 707 realizes the collection function when replacing the oil barrel.,

[0026] Workflow: When in use, connect the power supply and pour industrial oil above the coarse filter plate 403. At this time, the protective frame 402 has a good protective effect to prevent the oil from flowing out. The large-area setting of the coarse filter plate 403 solves the problem of slow feeding of industrial oil. The oil is in the treatment box 401, and the height of the oil level inside the treatment box 401 can be observed through the observation plate 404, which is convenient for speed control. The fine filter plate 405 can filter impurities in the oil. When the impurities are too many and block the fine filter plate 405, turn the observation plate 404 outwards, and then slide the fine filter plate 405 to the left to clean the impurities. The stop block 406 can ensure that the fine filter plate 405 is pressed. After the industrial oil is pretreated, it enters the separation filter machine body 2 through the through hole 407 and is purified by the separation filter machine. Turn the fixing screw 603 to separate it from the fixing block 602, and take out the shielding plate 604, the connecting telescopic rod 607 and the pressing plate 608 through the handle 606. The larger impurities after treatment fall onto the sponge plate 609 inside the treatment bin 601 through the impurity filter pipe 5. The oil in the impurities penetrates into the sponge plate 609. When the sponge plate 609 is saturated, it will drip into the connecting pipe 610 through the ventilation holes opened in the oil control plate 614. When the equipment work is completed, place the shielding plate 604 in the treatment box 601 and fix it by screwing the fixing screw 603 with the fixing block 602. Turn the limit screw 605 to make it press the pressing plate 608, and then the pressing plate 608 presses the sponge plate 609, so as to squeeze out the oil inside the sponge plate 609, and then enter the connecting pipe 610 through the ventilation holes opened on the upper and lower end faces of the oil control plate 614. Then, by opening the solenoid valve 612, the oil in the connecting pipe 610 and the treatment box 601 is discharged through the discharge pipe 613, avoiding environmental pollution and resource waste. The oil separated by the equipment flows out through the oil outlet pipe 702. At this time, placing an oil barrel below the oil outlet pipe 702 can achieve the collection work. When the amount of treated oil is relatively small and one oil barrel can complete the collection, there is no need for the collection function of the oil storage bottle 707. Embodiment 2

[0027] In Embodiment 2, the same parts as those in Embodiment 1 will not be described again. The difference is that when the amount of oil to be processed is large, the rotating plate 711 is rotated to make it located on the left side, and then under the action of the telescopic spring 704, the fixing frame 706 slides forward. The fixing frame 706 drives the oil storage bottle 707 to move forward, and the fixing frame 706 drives the sliding plate 708 to move forward, so that the oil storage bottle 707 is located below the oil outlet pipe 702. When replacing the oil barrel, the dripping oil can be collected to avoid polluting the working environment. The provided limit telescopic rod 705 and the guide plate 710 ensure that the fixing frame 706 slides stably towards the oil, so that it is accurately located below the oil outlet pipe 702. After the collection is completed, the oil can be processed by taking out the oil storage bottle 707. After the equipment is used up, the sliding plate 708 is squeezed backward, and then the rotating plate 711 is rotated to make it located above the top block 709, so as to fix the fixing frame 706.
