Description

Technical Field

[0001] The utility model relates to the technical field of waste lubricating oil filtering devices, in particular to a filtering device for recycling and processing waste lubricating oil. Background Art

[0002] Lubricating oil, commonly known as engine oil, is widely used in automobiles, ships, various industrial equipment and transmission parts of various machinery. During the use of lubricating oil, many oxidation products such as carboxylic acid, salts of organic acids, asphaltene, carbon residue, sludge, etc. are produced due to oxidation. Lubricating oil needs to be added during mechanical processing to lubricate the mechanical equipment.

[0003] In the prior art, a Chinese patent with publication number "CN209108714U" discloses a filtering device for waste lubricating oil recovery and processing. By providing a first mounting groove that can be fitted with a funnel, the waste lubricating oil can be poured into an oil storage barrel through the funnel, which can prevent the waste lubricating oil from splashing when pouring. The filtering device for waste lubricating oil recovery and processing is provided with a funnel, which can reduce the probability of waste lubricating oil splashing when pouring. The waste lubricating oil will enter the filter net after passing through the funnel, and will enter the oil storage barrel after primary filtration by the filter net, so that larger impurities in the waste lubricating oil can be filtered out, solving the problem that the waste lubricating oil generated during existing mechanical processing is generally poured directly into an oil storage barrel with a filter net during preliminary filtration, and the waste lubricating oil is easy to splash out during the process of pouring into the oil storage barrel, and the waste lubricating oil is easy to drip onto the ground.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] When lubricating oil needs to be replaced in time after being used for a period of time, waste lubricating oil can generally be recycled for reprocessing. During recycling, the lubricating oil needs to be initially filtered to filter out impurities in the waste lubricating oil. Some current filtering devices usually use filter plates to filter waste lubricating oil, but when there are too many impurities on the filter net, these impurities will clog the filter net, which will affect the filtering effect of the lubricating oil on the filter net.

[0029] The anti-blocking component is composed of a pushing component and a rotating component. The pushing component includes a positioning plate 3, on which an electric push rod 4 is fixedly mounted. The power source of the electric push rod 4 is mounted on the upper box body 101, and a control panel is also mounted on the upper box body 101. The control panel is used to start and stop the electric push rod 4. This technology is well known to people in this field and will not be described in detail here. A pushing plate 5 is fixedly mounted on the output end of the electric push rod 4, and a gear block 6 is fixedly mounted on the lower end face of the pushing plate 5.

[0030] The rotating assembly includes a rotating shaft 7, which is rotatably mounted inside the upper housing 101 through a driving shaft 15. A fixing frame 8 is fixedly mounted on the rotating shaft 7, and a scraper 9 is fixedly mounted on the lower end surface of the fixing frame 8. The scraper 9 has a low height and does not affect the flow of lubricating oil on the U-shaped filter plate 2. A driven gear 10 is fixedly mounted on the driving shaft 15. The driven gear 10 is located outside the upper housing 101, and the driven gear 10 is meshed with the gear block 6.

[0031] In this embodiment, the push plate 5 is driven to move reciprocatingly horizontally by the electric push rod 4, and the driven gear 10 is driven to rotate by the tooth block 6 on the push plate 5.

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, in order to clean the impurities on the U-shaped filter plate 2, a fixing component is used to achieve this effect. A fixing component is provided between the upper box 101 and the lower box 102, and the fixing component facilitates the disassembly and assembly of the upper box 101 and the lower box 102;

The flushing of the water flow facilitates the cleaning of impurities on the U-shaped filter plate 2, thereby improving the practicality of the device.

[0037] Working principle:

[0038] When in use, the waste lubricating oil to be filtered is poured into the interior of the filter box 1 from the liquid inlet 17 of the filter box 1. The waste lubricating oil entering the filter box 1 will be filtered through the U-shaped filter plate 2, and then the electric push rod 4 is started to reciprocate and drive the push plate 5 to move horizontally. The tooth block 6 on the push plate 5 is engaged with the driven gear on the drive shaft 15, and the push plate 5 drives the drive shaft 15 to reciprocate. The drive shaft 15 drives the fixed frame 8 to reciprocate through the rotating shaft 7. The scraper 9 on the fixed frame 8 scrapes off the impurities on the U-shaped filter plate 2 through the reciprocating rotation of the fixed frame 8, which can effectively prevent excessive impurities from accumulating on the U-shaped filter plate 2 and avoid affecting the filtering of the waste lubricating oil.

[0039] After the waste lubricating oil is filtered, the staff uses a tool to remove the fastening bolts 12, and then removes the lower box 102 installed on the upper box 101, and then uses water flow through an external water pipe to flush the U-shaped filter plate 2. The impurities on the U-shaped filter plate 2 can be cleaned by flushing with water flow. The impurities flushed from the U-shaped filter plate 2 will be discharged from the liquid inlet 17, and finally the U-shaped filter plate 2 and the lower box 102 can be reinstalled.
