Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the utility model discloses a negative pressure type oil filter, which comprises two parts of filtering and storing.

The storage part is composed of a negative pressure tank 21, a negative pressure pipe 22 welded on the negative pressure tank 21 and a valve 23 installed on the negative pressure tank 21, wherein the negative pressure pipe 22 is connected with a vacuum pump, and when the vacuum pump works, air in the negative pressure tank 21 is pumped out through the negative pressure pipe 22, and negative pressure is formed in the negative pressure tank. The valve 23 is a ball valve and is arranged on the side wall of the negative pressure tank 21 near the bottom, and when the valve 23 is opened, the edible oil in the negative pressure tank 21 flows out. A filter element 6 is plugged in a connecting pipe between the valve 23 and the filter tank 11, and the filter element 6 can carry out secondary filtration on the edible oil, so that the impurities in the edible oil are further reduced.

The main body of the filtering part is a filtering tank 11, an oil guide pipe 12 and an oil discharge pipe 13 are welded on the bottom surface of the filtering tank 11, the upper end of the oil guide pipe 12 penetrates through the top surface of the filtering tank 11 from bottom to top, and the lower end of the oil discharge pipe 13 penetrates through the bottom surface of the filtering tank 11 and is connected to a negative pressure tank 21.

Referring to fig. 1 and 2, the filter element has a core body 31, a filtering groove 32 is formed on the upper surface of the core body, a detention groove 33 is formed on the lower surface of the core body, and protrusions 4 are uniformly distributed on the bottom surface of the filtering groove 32. The core body 31 is also provided with two holes which are respectively sleeved on the oil guide pipe 12 and the oil discharge pipe 13 during installation. The filter cartridges are stacked in the filter tank 11 in a number of plural from bottom to top, and the filter paper 34 is placed between the adjacent filter cartridges.

Both passage a52 and passage B54 are located within core 31, with one end of passage a52 communicating with the retention groove 33 and the other end communicating with one of the holes in core 31. One end of the passage B54 communicates with the filter tank 32, and the other end communicates with another hole of the core body 31. The part of the oil guide pipe 12 positioned in the filter tank 11 is provided with an elongated groove A51, the part of the oil discharge pipe 13 positioned in the filter tank 11 is provided with an elongated groove B53, when the filter element is installed, two holes in the core body 31 are respectively sleeved on the oil guide pipe 12 and the oil discharge pipe 13, the inner walls of the holes seal most of the elongated groove A51 and the elongated groove B53, and only a small part of the holes is communicated with the channel A52 and the channel B54.

The blowoff valve 7 is mounted on the side of the canister 11 as close as possible to the bottom thereof.

The implementation principle of the embodiment is as follows:

the oil to be filtered is poured into the oil conduit 12, and is stopped after being filled, and then the vacuum pump connected to the negative pressure pipe 22 is started, and the vacuum pump pumps out the air in the negative pressure tank 21, so that the pressure of the negative pressure tank 21 is reduced. At this time, the air pressure in the filter tank 11 is higher than the air pressure in the negative pressure tank 21, and the oil in the oil conduit 12 starts to flow into the filter element.

The oil in the oil conduit 12 firstly flows into each channel A52 connected with the oil conduit 12 through the long groove B53 on the oil conduit 12, and then flows into the retention groove 33 of the corresponding filter element. The oil in the retention tank 33 passes through the filter paper 34 under pressure and flows into the filter tank 32 on the next filter cartridge, where the impurities are retained by the filter paper 34. The oil in the filter tank 32 flows into the oil drain pipe 13 through the passage B54 and the long groove B53, and then flows into the negative pressure tank 21 along the oil drain pipe 13.

The filtered oil is directly stored in the negative pressure tank 21, and when the valve 23 is opened in use, the oil in the negative pressure tank 21 flows out from the valve 23. Through the pipe connection between valve 23 and the negative pressure jar 21, should cut that the pipe internal stopper has one to cross filter core 6, can carry out the secondary to the oil that flows out and filter, further reduce the impurity in the oil on the one hand, on the other hand can avoid impurity to block up valve 23.

After a period of use, the canister 11 needs to be cleaned. In the cleaning, the upper lid of the canister 11 is opened, the filter element is taken out, the filter paper 34 is discarded, and then the impurities in the retention tank 33 are removed. The impurities on the inner wall and the bottom surface of the filter tank 11 also need to be cleaned together with oil stains, the drain valve 7 on the bottom surface of the filter tank 11 is opened during cleaning, the impurities are discharged while being cleaned, the drain valve 7 is closed after the cleaning is finished, and the filter element and new filter paper 34 are sequentially installed back.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
