Description

Technical Field

[0001] The invention relates to the technical field of vehicle lubricating oil recovery, in particular to a waste oil recovery and filtering device. Background Art

[0002] Waste oil recovery and filtration equipment is a device specially used for processing and recycling automotive lubricants. It can remove impurities, moisture and harmful substances in automotive lubricants, so that the automotive lubricants meet the standards for reuse. Through effective filtration and treatment, waste oil can meet the standards for reuse, realize the recycling of resources, and reduce dependence on new oil. When the waste oil recovery and filtration device is in use, a driving device is usually first required to drive the stirring blades to rotate, thereby mixing the automotive lubricant and chemical additives. The chemical reagent can reduce the interfacial tension between water and oil, making it easier for water droplets to gather into large droplets, thereby promoting separation. After mixing, it is injected into the heating tank to heat the automotive lubricant, reduce the viscosity of the automotive lubricant, and improve the subsequent filtration efficiency. During the heating process, multiple driving devices will be used to stir the automotive lubricant at multiple angles at the same time, thereby increasing the contact area between the automotive lubricant and the heating component. Finally, the impurities in the automotive lubricant are separated by the filtration equipment, thereby improving the purity of the automotive lubricant. During use, the existing waste oil recovery and filtering device can mix automotive lubricants and chemical additives. However, due to the relatively single stirring direction of the mixing equipment, the contact area between the automotive lubricants and the chemical additives is limited, thereby reducing the water separation efficiency. During the heating process, although the automotive lubricants can be stirred at multiple angles simultaneously by multiple driving devices, the internal structure of the heating tank will be more complicated, which will result in a reduction in the storage space inside the heating tank, thereby reducing the amount of automotive lubricants heated each time and reducing the heating efficiency of the automotive lubricants. Although the filter assembly can be installed and fixed by bolt connection during installation, the operation is relatively cumbersome, which will increase the time required for subsequent replacement of the filter assembly. In addition, the bolts will corrode and fall off after long-term use, ultimately reducing the stability of the filter assembly. For this reason, we propose a waste oil recovery and filtering device.

After the automotive lubricating oil is extracted, the delivery pump 23 stops running through the control of the control switch group 2, and then the connecting valve and the delivery valve are closed. At this time, the drain valve is opened, and the water accumulated at the bottom of the separation tank 3 will be discharged through the drain pipe 21.

[0029] Among them: a delivery pump 26 is provided on the right side of the upper end of the base 1, the right end of the heating tank 4 is connected to the left end of the delivery pump 26 through a mounting pipe 27, and a mounting valve is connected in series in the middle of the mounting pipe 27.

The delivery pump 26 extracts the heated vehicle lubricating oil through the mounting pipe 27, and then the delivery pump 26 injects the heated vehicle lubricating oil into the interior of the filter box 5 through the fixed pipe 28.

[0030] The working principle of the waste oil recovery and filtration device provided by the present invention is as follows: Before use, first connect the oil inlet pipe 20, the drain pipe 21 and the oil drain pipe 22 to the external pipe, and then insert the new filter 19 into the interior of the filter box 5. At this time, the operator rotates the adjusting wheel 89, and the adjusting wheel 89 drives the worm gear 87 to rotate through the worm 88. During the rotation of the worm gear 87, the push plate 86 is driven to rotate through the transmission rod 85. The push plate 86 gives the pressure plate 83 a downward thrust during the rotation, so that the push plate 83 drives the top block 84 to move downward, and the spring 15 extends. When the lower end of the top block 84 contacts the upper end of the trapezoidal block 18, the top block 87 gives the trapezoidal block 18 a leftward thrust, so that the trapezoidal block 18 drives the filter 19 to move to the left through the fixed plate 17, and finally makes the left end of the fixed plate 17 contact the filter. The right end of the filter box 5 is tightly attached to achieve the installation and fixation of the filter screen 19. During the use of the waste oil recovery and filtering device, the oil inlet valve is opened, and the vehicle lubricating oil and chemical additives are injected into the interior of the separation tank 3 through the oil inlet pipe 20. After the addition is completed, the oil inlet valve is closed, and then the control switch group 2 is controlled to control the drive motor 68 to start running. The output shaft of the drive motor 68 drives the driving bevel gear 69 to rotate, and the driving bevel gear 69 drives the two bevel gears 66 to rotate through the meshing connection, so that the bevel gear 66 drives the installation cylinder 61 and the vertical rod 64 to rotate. The directions of the installation cylinder 61 and the vertical rod 64 are opposite. The installation cylinder 61 drives the vertical plate 63 to rotate through the connecting plate 62, and the vertical rod 64 drives the stirring fan blade 65 to rotate, thereby The oil and chemical additives are mixed. The chemical reagents can reduce the interfacial tension between water and oil, making it easier for water droplets to gather into large droplets, thereby promoting separation. After mixing, the drive motor 68 stops running by controlling the switch group 2, and the automotive lubricating oil is allowed to stand for a period of time to allow the water to naturally settle to the bottom of the separation tank 3. After standing for a period of time, the connecting valve and the delivery valve are opened, and then the delivery pump 23 starts running by controlling the switch group 2. The delivery pump 23 extracts the dehydrated automotive lubricating oil through the connecting pipe 24, and then injects it into the interior of the heating tank 4 through the delivery pipe 25. After the automotive lubricating oil is extracted, the delivery pump 23 stops running by controlling the switch group 2, and then the connecting valve and the delivery valve are closed. At this time, the drainage is opened. Valve, the water accumulated at the bottom of the separation tank 3 will be discharged through the drain pipe 21, and the electric heating wire 29 will start to operate by controlling the switch group 2, and the vehicle lubricating oil will be heated by the electric heating wire 29 to reduce the viscosity of the vehicle lubricating oil and improve the subsequent filtration efficiency. During the heating process, the motor 11 starts to operate by controlling the switch group 2, and the output shaft of the motor 11 drives the center wheel 12 to rotate, and the center wheel 12 will drive the adjusting rod 13 to rotate around the axis of the center wheel 12. Since the adjusting rod 13 and the axis of the center wheel 12 do not coincide, the adjusting rod 13 will produce lateral and vertical displacements during the circular motion, so that the adjusting rod 13 will slide and rotate relative to each other in the adjusting groove, and then with the rotation of the center wheel 12,The adjusting rod 13 drives the rack plate 10 to perform a horizontal reciprocating motion through the mounting plate 14. When the rack plate 10 moves to the left, the rack plate 10 drives the drive gear 77 to rotate through the meshing connection. The drive gear 77 drives the adjusting plate 72 to rotate through the mounting rod 71. The adjusting plate 72 drives the stirring blade 2 74 to rotate through the connecting rod 73. When the rack plate 10 moves to the right, the rack plate 10 drives the drive gear 77 to rotate and reset through the meshing connection. The drive gear 77 drives the adjusting plate 72 to rotate and reset through the mounting rod 71. The adjusting plate 72 drives the stirring blade 2 74 to rotate and reset through the connecting rod 73, thereby stirring the automotive lubricating oil. During the rotation of the connecting rod 73, the gear 76 rotates around the inner gear ring 7 5 revolves, causing the connecting rod 73 to rotate while driving the stirring blade 2 74 to rotate, further increasing the contact area between the vehicle lubricating oil and the electric heating wire 29. After heating the vehicle lubricating oil, the installation valve and the fixed valve are opened. Then, through the regulation of the control switch group 2, the delivery pump 26 begins to operate. The delivery pump 26 extracts the heated vehicle lubricating oil through the installation pipe 27. Then, the delivery pump 26 injects the heated vehicle lubricating oil into the interior of the filter box 5 through the fixed pipe 28. The filter 19 separates impurities in the vehicle lubricating oil, thereby improving the purity of the vehicle lubricating oil.
