The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

fig. 1 is a cross-sectional view of the present utility model.

Fig. 2 is a partial schematic view of fig. 1.

In the figure: the device comprises a shell 1, a liquid inlet 2, a liquid outlet 3, a sewage outlet 4, a partition plate 5, a filtering area 6, a sewage area 7, a filter screen cylinder 8, a valve core 9, a connecting rod 10, an operating rod 11, a spring 12, a limiting plate 13, a magnet 14 and a blow-down valve 15.

Detailed Description

As shown in fig. 1, the anti-clogging filter for regenerating the waste lubricating oil comprises a shell 1, wherein a liquid inlet 2 is formed in the upper end of the shell 1, a liquid outlet 3 is formed in one side of the shell, and the liquid inlet 2 and the liquid outlet 3 are connected into a raw oil conveying system. A drain outlet 4 is arranged at the bottom of the shell 1, and the drain outlet 4 is used for discharging sundries and avoiding blocking the pump body. A baffle plate 5 is arranged in the shell 1, and a filtering area 6 and a sewage draining area 7 are arranged between the upper and lower sections of the baffle plate 5. Wherein, the filter area 6 is vertically provided with two groups of filter screen barrels 8, and the filter screen barrels 8 are vertically arranged at intervals in a nested manner. The upper ends of the two groups of filter screen barrels 8 are propped against the top of the shell 1, and the lower ends of the two groups of filter screen barrels 8 are embedded into a positioning ring at the bottom of the shell 1. The mesh of the inner filter screen cylinder 8 is larger than that of the outer filter screen cylinder 8, thereby realizing secondary filtration. The top end of the inner filter screen cylinder 8 is communicated with the liquid inlet 2, and oil in the liquid inlet 2 is filtered by the inner filter screen cylinder 8, then filtered by the outer filter screen cylinder 8, and finally flows out from the liquid outlet 3. And the residue dirt is deposited to the partition plate 5 below the two groups of filter screen drums 8.

In order to facilitate periodic cleaning of the residual dirt, a first opening is provided at the partition plate 5 corresponding to the inner filter screen cylinder 8, and a second opening is provided at the partition plate 5 corresponding to the interval between the outer filter screen cylinder 8 and the inner filter screen cylinder 8. The first opening and the second opening are blocked by the valve core 9. The lower end of the valve core 9 is connected with an operating rod 11 through a connecting rod 10. The operating rod 11 passes through the bottom of the sewage disposal area 7 in a sealing way, the operating rod 11 is positioned outside the shell 1 and sleeved with a spring 12, one end of the spring 12 is propped against the end face of the shell 1, and the other end is propped against a limiting plate 13 at the end head of the operating rod 11. In general, the limiting plate 13 can be pushed out outwards by the elastic force of the spring 12, so that the valve core 9 is pressed at the first opening and the second opening. When cleaning is needed, the limiting plate 13 can be pressed upwards, the valve core 9 is separated from the first opening and the second opening, and the residue dirt falls into the sewage disposal area 7 from the first opening and the second opening and is finally discharged from the sewage disposal outlet 4.

The upper end of the limiting plate 13 is embedded with a magnet 14. When the limiting plate 13 is pressed upwards, the magnet 14 can be magnetically adsorbed and fixed with the shell 1, so that the opening time of the valve core 9 can be controlled according to the needs, and manual long-time pressing is not needed.

A vent valve 15 is arranged at the top of the housing 1. The internal and external air pressures can be balanced.

The top of the shell 1 is connected with the sealing cover through bolts, and when the filter screen cylinder 8 needs to be taken out for cleaning, the sealing cover can be opened, and the filter screen cylinder 8 can be directly taken out.

Working principle and process:

1) And (3) filtering: during normal use, oil enters from the liquid inlet 2, is filtered for the first time through the inner filter screen cylinder 8, is filtered for the second time through the outer filter screen cylinder 8, and is discharged from the liquid outlet 3.

2) Cleaning: the upper vent valve 15 is opened to balance the internal and external air pressure of the filter, the valve core 9 is opened, and the polluted liquid can naturally flow out, so that the polluted liquid is effectively prevented from splashing randomly. And then the upper sealing cover is detached, and the filter screen cylinder 8 can be taken out for cleaning.
