Description

Vacuum Oil Filter

The present invention relates to a vacuum oil filter device, more precisely, to a vacuum oil filter device capable of maintaining air density for a long time.

The conventional vacuum oil filter device used to filter oil cannot maintain the air density of the filter space for a long time during the oil filter process, and the user needs to monitor the vacuum pressure value of the filter device all the time during the operation of the filter device. It is very troublesome and energy-consuming to turn on the vacuum pump in time to maintain the vacuum in the container; in addition, the oil produced under the unstable air density has the problem of easy deterioration. In addition, the conventional oil filtering device has a complex structure, not only is it not easy to clean, but impurities may pass through the filter material during the filtering process, so a second or even third filtering is required to completely filter.

Based on the above deficiency, the present invention provides a vacuum oil filter device, which has a simple structure and can provide long-term and stable air density, which is convenient for users to use.

Based on the above purpose, the present invention provides a vacuum oil filter device, which includes a filter barrel with an oil filter channel connected up and down, a filter assembly is arranged in the oil filter channel; an air extraction unit is located on one side of the filter barrel, has A one-way valve is connected to a pipeline, and the pipeline communicates with one side of the filtering bucket and a bottom surface, wherein the bottom surface of the filter barrel has a mounting seat to be placed in the opening of an oil storage container, and a mounting platform is protruded downward from the mounting seat, and an air-tight ring is provided on the outer edge of the mounting platform and the oil storage container The opening is tight.

Wherein, the inner wall of the filter bucket is provided with a guide wall in the shape of a funnel, and the top edge of the guide wall is provided with a stepped bearing part to horizontally position the filter assembly. The filter assembly includes a filter paper and a partition. The filter paper Both the partition and the partition are circular, and the radius of the filter paper is greater than the radius of the partition, so that the filter paper covers a plurality of holes in the partition, wherein the air extraction unit is provided with a pressure sensor connected to the pipeline, the The pressure sensor can be a vacuum pressure gauge for detecting the vacuum pressure inside the oil storage container.

Preferably, the filter barrel is made of stainless steel, which can avoid explosion or rupture during use.

Preferably, the user can place a second oil storage container inside the oil storage space as required. In addition to keeping the oil storage container clean, the user can also directly seal the second oil storage container after filtering the oil. The oil container improves the convenience of use.

Fig. 3 is a sectional view of the vacuum oil filter device.

In order to clearly illustrate the specific implementation method, structure and achieved effects of the present invention, it is described as follows with reference to the drawings: Please refer to Fig. 1 to Fig. 3, a vacuum oil filter device 100 is shown in the figure, which includes a filter barrel 10 with an upper and lower connection An oil filter channel, a filter assembly 11 is installed in the oil filter channel, an air extraction unit 12 is installed on one side of the filter barrel 10, and a mounting seat 13 is located on the bottom surface of the filter barrel 10, so that the filter barrel 10 can be used The installation seat 13 is arranged on the opening of an oil storage container 20 . Wherein, the inner wall of the filter barrel 10 (that is, the lower section of the oil filter channel) is provided with a guide wall 15 in the shape of a funnel, and the top edge of the guide wall 15 is provided with a stepped bearing portion 151 to horizontally position the filter. Assembly 11; the air extraction unit 12 has a one-way valve 122 connected to a pipeline 121, and the pipeline 121 communicates with an opening 14 on the side of the filter bucket 10 and a vent hole 133 on the bottom surface of the mounting seat 13, so that the air extraction unit 12 communicates The oil storage container 20; in addition, the mounting seat 13 of the filter barrel 10 has a ring-shaped flat ring wall positioned above the opening of the oil storage container 20, and a mounting platform 131 protrudes downward from the inner peripheral edge of the flat ring wall It extends into the opening of the oil storage container 20, and is provided with an airtight ring 132 sleeved on the outer edge of the installation platform 131 and cushioned against the lower edge of the flat ring wall to press against the oil storage container in an airtight manner. 20 to the top edge of the opening. During use, the weight of the filter barrel 10 and the filter assembly 11, and the weight of the grease to be filtered, press down against the opening of the oil storage container 20 through the flat ring wall and the air-tight ring 132, so that the mounting seat 13 is in close contact with the opening of the oil storage container 20 .

Wherein, the filter assembly 11 includes a filter paper 111 and a partition 112, the filter paper 111 is covered on the partition 112 to cover a plurality of holes of the partition 112, and the partition 112 is engaged with the loading portion 151 . In this embodiment, both the filter paper 111 and the separator 112 are circular, and the radius of the filter paper 111 is larger than the radius of the separator 112 . The filter paper 111 can be adsorbed on the separator 112 by the weight of the oil to be filtered and the vacuum suction, and no additional clamping device is needed to clamp and fix the filter paper 111 .
