Description

Technical Field

[0001] The utility model relates to the technical field of oil absorption filtration, in particular to a vacuum automatic oil absorption filtration device. Background Art

[0002] In precision industries such as pressure sensors, it is necessary to pour silicone oil into the pressure sensors. When pouring silicone oil, the pressure sensors are usually soaked in silicone oil and left standing, which results in most of the silicone oil being reused multiple times. During the use process, impurities will be mixed into the silicone oil, and it needs to be filtered. Since the pressure sensors have high requirements for the cleanliness of silicone oil, this makes the requirements for filtering silicone oil very high. If a self-priming pump is used to suck and filter the silicone oil, it will cause pollution to the silicone oil again due to the incomplete cleaning of the self-priming pump. And using manual filtration has very low production efficiency. Content of the Utility Model

[0022] The following will be combined with the attached Figures 1 - 5 to make a further detailed description of the present utility model:

[0023] Referring to Figure 1 , the present utility model provides a vacuum automatic oil suction and filtration device, which is used to solve the problem of automatically sucking and filtering silicone oil when the silicone oil is reused multiple times during the silicone oil perfusion process of a pressure sensor. A vacuum automatic oil suction and filtration device is provided, which includes a cabinet 1 and a coarse filtration mechanism 2, a fine filtration mechanism 3, a vacuum system 4 and an oil receiving device 5 arranged in the cabinet 1; the coarse filtration mechanism 2 is arranged on the middle support surface of the cabinet 1 and is used to automatically suck and perform coarse filtration on the silicone oil in the tray. The fine filtration mechanism 3 and the coarse filtration mechanism 2 are placed on the middle support surface of the cabinet 1 together and are used to automatically suck and perform fine filtration on the silicone oil of the coarse filtration mechanism 2. The vacuum system 4 is placed at the bottom of the cabinet 1 and is used to provide a vacuum environment for the device. The oil receiving device 5 is a device for placing the remaining silicone oil from flowing out when the coarse filtration mechanism 2 and the fine filtration mechanism 3 need to replace the filter element.

[0024] Referring to Figure 2 , the coarse filtration mechanism 2 includes an oil suction hose 2.1, a coarse filter 2.2 and a filter oil tank 2.3. The oil inlet of the coarse filter 2.2 is connected to the oil suction hose 2.1, and its oil outlet is connected to the oil inlet of the filter oil tank 2.3 through a hose.

[0025] Further, a first pneumatic baffle valve 2.4 is provided at the oil inlet of the filter oil tank 2.3, a first manual negative pressure valve 2.5 is provided on the tank cover of the filter oil tank 2.3, a first automatic negative pressure valve 2.6 is provided at the negative pressure interface of the filter oil tank 2.3, and a first right-angle pneumatic baffle valve 2.7 is provided at the oil outlet of the filter oil tank 2.3.

[0026] In this embodiment, the working mode of the coarse filtration mechanism 2 is as follows: Manually place the oil suction port of the oil suction hose 2.1 into the silicon oil tank to be filtered, click the start button, the vacuum pump 4.1 is turned on, the filter oil tank 2.3 enters the vacuum state, and the silicon oil passes from the oil suction port of the oil suction hose 2.1 through the coarse filter 2.2 to the first pneumatic baffle valve 2.4 and then enters the filter oil tank 2.3 for temporary storage, completing the coarse filtration of the silicon oil. Since the filter oil tank 2.3 is in a vacuum state after coarse filtration, when performing cleaning and maintenance on it, it is necessary to manually unscrew the first manual pressure recovery valve 2.5 to make the filter oil tank 2.3 return to normal pressure.

[0027] Refer to Figure 3 , the fine filter 3 includes a fine filter 3.1 and a storage oil tank 3.2. The oil inlet of the fine filter 3.1 is connected to the oil outlet of the filter oil tank 3.2 through a hose, and its oil outlet is connected to the storage oil tank 3.2;

[0028] Further, a second manual negative pressure valve 3.3 is provided on the tank cover of the storage oil tank 3.2, a second automatic negative pressure valve 3.4 is provided at the negative pressure interface of the storage oil tank 3.2, a second right-angle pneumatic baffle valve 3.5 is provided at the oil outlet of the storage oil tank 3.2, and a hand valve 3.6 is provided at the manual oil receiving port of the storage oil tank 3.2.

[0029] In this embodiment, the working mode of the fine filtration mechanism 3 is as follows: Manually click the filtration button, the vacuum pump 4.1 starts, the storage oil tank 3.2 enters the vacuum state, the second automatic pressure recovery valve 2.6 automatically returns the filter oil tank 2.3 to normal pressure, and the silicon oil enters the storage oil tank 3.2 from the filter oil tank 2.3 through the fine filter 3.1 for storage and standby, completing the fine filtration of the silicon oil. When manual oil receiving is required, unscrew the second manual pressure recovery valve 3.3 to return the storage oil tank 3.2 to normal pressure, unscrew the hand valve 3.6 for manual oil receiving. When automatic oil receiving is required, press the oil outlet button, the second automatic pressure recovery valve 3.4 returns the storage oil tank 3.2 to normal pressure, and the second right-angle pneumatic baffle valve 3.5 opens, and the equipment starts to automatically discharge oil.

[0030] Refer to Figure 3 , the vacuum system 4 includes a vacuum pump 4.1, and the vacuum pump 4.1 is respectively connected to the filter oil tank and the storage oil tank.

[0031] Further, the vacuum system 4 further includes a main pipeline, a first branch pipeline, and a second branch pipeline. The vacuum pump 4.1 is communicated with the main pipeline. The first branch pipeline and the second branch pipeline are connected to the main pipeline in parallel, and the first branch pipeline and the second branch pipeline are respectively connected to the filter oil tank 2.3 and the storage oil tank 3.2.

[0032] Still further, a differential pressure inflation valve 4.2 and a vacuum pressure gauge 4.3 are provided on the main pipeline; second pneumatic baffle valves 4.4 are provided on both the first branch pipeline and the second branch pipeline.

[0033] In this embodiment, the working mode of the vacuum system 4 is as follows: The vacuum pump 4.1 is started to provide negative pressure for the equipment. At the same time, the differential pressure inflation valve 4.2 works. When the equipment suddenly loses power, the differential pressure inflation valve 4.2 closes, and at the same time, the vacuum pump 4.1 is connected to the atmosphere in the reverse direction, protecting the vacuum pump 4.1 and preventing the vacuum pump 4.1 from backflowing oil, causing pollution to the cavities of the filter oil tank 2.3 and the storage oil tank 3.2.

[0034] Refer to Figure 5 , the coarse filtration mechanism 2 and the fine filtration mechanism 3 are located above the oil receiving device 5. The oil receiving device 55 includes a profile frame 5.1, an oil receiving box 5.2, and a drawer 5.3. The oil receiving box 5.2 is located on the drawer 5.3, and the drawer 5.3 is slidably arranged within the profile frame 5.1.

[0035] Further, the oil receiving device is similar to the drawer structure of a table or a wardrobe. In order to ensure better sliding of the drawer 5.3, a slide rail is provided within the profile frame 5.1 and a pulley is provided at the bottom end of the drawer 5.3.

[0036] In this embodiment, the working mode of the oil receiving device 5 is as follows: When the filter element of the coarse filter 2.2 and the fine filter 3.1 is replaced, the remaining silicone oil will flow out and reach the drawer 5.3 through the oil receiving box 5.2. When the silicone oil in the drawer 5.3 accumulates to a certain amount, the drawer 5.3 is manually pulled out, the silicone oil is poured out, and then it is placed back in the original position.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
