For easy understanding, the innovation points of the scheme are described below:

1. the low-pressure filtering mode of the pumping pipeline solves the problem that the thick oil can be filtered only to a certain extent in the traditional mode;

the traditional setting mode (refer to CN201410064831.5 patent) can not be used for normal filtration when the amount of thickened oil is small; the reason is that: (1) when the oil quantity is small, the pores on the surface layer of the filter medium cannot be filled with the thick oil, so that high-pressure gas flows from the inner barrel to the outer barrel through the pores on the surface layer of the filter medium which is not filled with the oil, and the thick oil cannot be filtered at normal high pressure; (2) in addition, in the traditional filtering mode, high-pressure gas is pumped into the inner barrel for filtering, and other high-pressure gas can lead to the compression of the filtering media, so that the pores between the filtering media are reduced, and thick oil cannot be naturally filtered under the condition of gravity;

in the scheme, the filtering is performed in a low-pressure extraction mode; when the amount of the thickened oil is small, the problem that the thickened oil cannot be filtered normally because the inner barrel and the outer barrel are communicated through the pores directly by air pressure exists; however, due to the low pressure, the filter media cannot be compressed, the pores among the filter media are larger, and the thick oil can naturally form filtration under the action of the thick oil; therefore, even if the thick oil is less, the scheme can still realize filtration;

2. the arrangement of the material receiving hopper and the material receiving cylinder solves the problem that the internal filter medium is not easy to replace;

because the thick oil contains a plurality of impurities, the pores of the filter medium are very easy to be filled with impurities, so that the filter medium needs to be replaced periodically, and the replacement frequency is high;

when the traditional structure is used for replacing the filter medium, the traditional structure can only be replaced by uncovering the barrel cover, so that the efficiency is low;

according to the scheme, the filter medium with sundries can be directly discharged through the material receiving hopper, the material receiving cylinder and the inclined screen plate, and meanwhile, the filter medium is installed through the medium inlet, so that the scheme is simple, quick and convenient;

3. the extraction mode of the low-pressure pipeline and the arrangement of the sealing component ensure that the whole device has good sealing effect;

the traditional oil filtering device is pressed under high pressure; if the barrel cover is not tightly sealed, the air pressure is easy to leak, so that the air pressure in the inner barrel is unstable, and the condition of incapability of filtering well is caused;

in this scheme, owing to be the low pressure extraction, not only realized filtering when the pressure is taken out and still let filtering component compress tightly interior bucket, outer bucket automatically under the effect of pressure, sealed well.

The utility model has the following advantages:

(1) The low-pressure extraction mode ensures that a small amount of thick oil can be filtered;

(2) The arrangement of the material receiving hopper and the material receiving barrel ensures that the filter medium can be normally replaced under the condition that the barrel cover is not opened, and the replacement is simple, convenient and quick;

(3) The whole device keeps good sealing effect, thereby ensuring good air pressure environment in the device and being beneficial to filtration.
