Description

Technical Field

[0001] The utility model relates to the technical field of waste oil separation, in particular to a waste oil separation device. Background Art

[0002] Waste oil refers to waste lubricating oil replaced from various machines, vehicles and ships. During the use of lubricating oil, due to the pollution of its own oxides by the outside world, a large amount of colloid and oxides are produced, which reduces or even loses its functions of controlling friction, reducing wear, cooling, sealing and isolating, and reducing vibration, so it has to be replaced. The organic compounds containing chlorine, sulfur, phosphorus, etc. are toxic, and many countries in the world list them as hazardous waste.

[0003] In the process of recycling waste oil, filtering the impurities therein is an indispensable step. Chinese patent CN217041648U discloses a waste oil impurity separation device, which drives the driven gear and the reciprocating screw to rotate and prompts the pressing plate to move up and down, and then squeezes the waste oil through the pressing plate, and filters the waste oil through the filter holes, and then collects the filtered waste oil through the oil storage barrel and reuses it, thereby improving the utilization rate of the waste oil.

[0004] However, by comparing the above existing documents, the inventors believe that there are the following defects:

[0005] The comparative document filters the impurities in the waste oil through the filter holes on the surface of the separation cylinder. When too many impurities are filtered, the filter holes are easily blocked by the impurities, and then the machine needs to be stopped to clean the impurities that block the filter holes. This will undoubtedly greatly affect the efficiency of waste oil impurity filtering. In view of this, we propose a waste oil separation device to solve the above problems. Utility Model Content

[0026] See also Figure 2 and Figure 3 A driving assembly for driving the first filter element 2 and the second filter element 3 to move is arranged inside the box body 1, and the driving assembly includes two groups of tooth blocks 5, wherein the two groups of tooth blocks 5 are respectively fixedly mounted on the bottom of the first filter element 2 and the top of the second filter element 3, and two slide grooves 9 extending to the inside of the connecting cover 4 are provided on the inner walls on both sides of the box body 1, and sliders 10 extending to the inside of the corresponding slide grooves 9 are fixedly mounted on both sides of the first filter element 2 and the second filter element 3, and a first motor 6 is fixedly mounted on the outside of the box body 1, and a rotating shaft extending to the inside of the box body 1 is fixedly mounted on the output end of the first motor 6, and a gear 7 meshing with the two groups of tooth blocks 5 is fixedly mounted on the other end of the rotating shaft.

[0027] Among them, by setting the first filter element 2 and the second filter element 3, when filtering impurities in the waste oil, one of the filter elements is used for filtering first, and when the filter element is blocked, the first motor 6 can be started to drive the gear 7 to rotate, so that the first filter element 2 and the second filter element 3 are moved in opposite directions through the gear block 5, so that the waste oil is continued to be separated and filtered through the other filter element, thereby avoiding the need to stop the machine to clean impurities as much as possible, and greatly improving the efficiency of separating and filtering impurities in the waste oil.

[0028] In this embodiment, the oil inlet pipe 13 is fixedly installed on the top of the box body 1, and a deflector hood 14 is fixedly installed on the inner top wall of the box body 1. The direction of the port of the deflector hood 14 is biased toward one side of the connecting hood 4. The first filter element 2 and the second filter element 3 are distributed up and down, and a cover door 8 is hinged on the side of the connecting hood 4 away from the box body 1.

[0029] Among them, by setting the guide cover 14, the two filter elements can still perform the work of separating and filtering impurities in the waste oil when adjusting their positions, reducing the probability of incomplete filtering of impurities in the waste oil due to staggered gaps.

[0030] In addition, the impurities blocking the filter element can be cleaned by opening the cover door 8.

[0031] See also Figure 4 In this embodiment, the first filter element 2 and the second filter element 3 both include a fixed frame 201, a connecting strip 202 and a filter screen 203. The connecting strips 202 are fixedly installed on both sides of the filter screen 203, and the fixed frame 201 is installed on the outside of the connecting strips 202 and the filter screen 203. A connecting component for installing the filter screen 203 is provided between the fixed frame 201 and the connecting strip 202. The connecting component includes a first magnetic block 11 fixedly installed on the inner wall of the fixed frame 201, and a second magnetic block 12 is fixedly installed inside the connecting strip 202. The magnetic forces of the first magnetic block 11 and the second magnetic block 12 are mutually attracted.

[0032] The first magnetic block 11 and the second magnetic block 12 are provided to facilitate fixing the filter 203 inside the fixing frame 201, thereby facilitating the disassembly and assembly of the filter 203, and further facilitating the cleaning or replacement of the filter 203.

[0033] In addition, the filter 203 is located inside the fixed frame 201, so that impurities on the filter 203 can be easily driven into the inside of the connecting cover 4, which is convenient for subsequent cleaning of impurities and also convenient for subsequent flushing of both sides of the filter 203.

[0034] See also Figure 5 In this embodiment, a water tank 25 is fixedly installed on the outside of the box body 1, and a cleaning component for flushing the first filter element 2 and the second filter element 3 is also provided inside the box body 1. The cleaning component includes a water pump 21 fixedly installed on the inner wall of the water tank 25, a water suction pipe is fixedly installed on the input end of the water pump 21, and a hose 22 extending to the inside of the box body 1 is fixedly installed on the output end of the water pump 21. A shunt pipe 20 is fixedly installed at one end of the hose 22 located inside the box body 1, and a plurality of nozzles 23 are fixedly installed at the bottom of the shunt pipe 20.

[0035] It is worth noting that the hose 22 is fixed at the connection with the inner wall of the box body 1 .

[0036] The water pump 21 can pump out the water in the water tank 25 for flushing the filter 203 .

[0037] After the impurities in the waste oil are filtered and separated, the two filter screens 203 are taken out to clean the impurities on the surfaces of the two filter screens 203 . For impurities that are inconvenient to clean, the water pump 21 can be started to flush the impurities remaining on the surfaces of the filter screens 203 through the nozzle 23 .

[0038] In this embodiment, a second motor 15 is fixedly installed on the outside of the box body 1, and a screw rod 16 rotatably connected to the inner wall of the box body 1 is fixedly installed on the output end of the second motor 15. A threaded block 18 is threadedly installed on the surface of the screw rod 16. A sliding rod 17 is also fixedly installed on the inner wall of the box body 1, and a connecting block 19 is slidably installed on the outside of the sliding rod 17. The shunt pipe 20 is fixedly installed at the bottom of the threaded block 18 and the connecting block 19.

[0039] In addition, by starting the second motor 15 to drive the screw rod 16 to rotate back and forth, the nozzle 23 can be moved synchronously, thereby improving the comprehensiveness of flushing.

[0040] It is worth noting that sealing sleeves are provided at the connection between the rotating shaft and the screw rod 16 and the inner wall of the box body 1 to ensure the sealing of the connection so that the waste oil is not easily leaked out of the box body 1.

[0041] In this embodiment, a water supply pipe is fixedly installed on the top of the water tank 25, an oil discharge pipe 24 is fixedly installed on one side of the box body 1, and an observation window 26 is embedded on the surface of the box body 1.

[0042] The water adding pipe is used to add water for cleaning into the water tank 25, the oil drain pipe 24 is used to discharge the waste oil after impurities are filtered and separated, and the setting of the observation window 26 is convenient for the staff to observe the liquid level of the filtered waste oil.

[0043] When the present embodiment is in use, waste oil enters the interior of the casing 1 through the oil inlet pipe 13, and impurities in the waste oil can be filtered and separated through the first filter element 2. When the first filter element 2 is blocked, the staff can start the first motor 6 to drive the gear 7 to rotate, so that the first filter element 2 moves toward the interior of the connecting cover 4, and the second filter element 3 moves toward the interior of the casing 1. The second filter element 3 continues to filter and separate impurities in the waste oil. The staff of the first filter element 2 that enters the connecting cover 4 can open the cover door 8 to take out the internal filter screen 203 and then clean the impurities blocked therein, thereby greatly improving the efficiency of separating and filtering impurities in the waste oil and avoiding the need to stop the machine to clean impurities as much as possible.

[0044] When it is necessary to flush the two filter elements, after the filtering and separation of impurities in the waste oil is completed, the two filter screens 203 are taken out to clean the impurities on the surfaces of the two filter screens 203. For impurities that are inconvenient to clean, the water pump 21 can be started to flush the impurities remaining on the surface of the filter screen 203 through the nozzle 23. At the same time, the second motor 15 is started to drive the screw rod 16 to rotate reciprocatingly, so that the nozzle 23 can move synchronously. After cleaning one side, the filter screen 203 that has been flushed on one side is taken out to flush the filter screen 203 inside the other filter element. At the same time, the filter screen 203 on one side that has been flushed is reversely inserted into the interior of the fixed frame 201. The filter screen 203 can be thoroughly flushed in this reciprocating manner, which reduces the probability of subsequent impurities clogging the filter screen 203.
