Description

Technical Field

[0001] The utility model belongs to the technical field of demisters and relates to a demister, in particular to an oil tank demister for a lubricating oil station. Background Art

[0002] Oil mist separator, also known as oil mist recovery, is a kind of oil mist separator installed on various machining equipment such as CNC machining centers, cleaning machines, die-casting machines, CNC lathes, etc., to absorb the oil mist in the machining chamber to purify the air and protect the health of workers. With the development of business, the rapid increase of machine tools and the improvement of national income, a comfortable working environment is required. The oil mist generated by general processing machines will cause lung, liver, laryngeal cancer and other diseases after being inhaled by the human body for a long time, and may induce chronic eye diseases, skin oil rashes, etc.

[0003] After searching, for example, a Chinese patent document discloses a lubricating oil station automatic oil collection tank defogger [Application No.: 202220989048.X; Publication No.: CN 217030759 U]. This lubricating oil station automatic oil collection tank defogger includes a defogger body, a stainless steel frame is placed inside the defogger body, a glass fiber filter element is arranged in the stainless steel frame, a support plate is fixed on the left side of the defogger body, a fan is connected to the top of the support plate, an air duct is connected to the top of the fan, and one end of the air duct is connected to the back of the defogger body. The utility model starts the fan, which generates suction to draw oil from the oil tank into the demister body. The oil mist is separated into air and oil droplets after passing through the glass fiber filter element. The clean air is discharged through the fan, and the oil droplets return to the oil tank through the oil return pipeline. The glass fiber filter element is made of glass fiber composite and supported by a stainless steel skeleton. The glass fiber can efficiently capture fine oil mist particles and form large droplets through coalescence. The large droplets are separated and return to the oil tank by gravity.

[0004] The stainless steel skeleton disclosed in the patent supports the glass fiber filter element through the stainless steel skeleton. The glass fiber can efficiently capture fine oil mist particles and form large droplets through agglomeration. The large droplets are separated and return to the oil tank by gravity. However, a part of the oil will be adsorbed on the glass fiber filter element, which will clog the filter pores of the glass fiber filter element over time and reduce the service life of the demister.

The technical problem to be solved by the utility model is: how to clean the oil stains adsorbed on the filter element to avoid clogging the filter holes of the filter element after drying.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A lubricating oil station oil tank defogger comprises a defogger body, the defogger body is provided with an air inlet pipe and an air outlet pipe, the air outlet pipe is fixed with a fan, an oil outlet is provided at the bottom of the defogger body, a filter element is fixed inside the defogger body, a scraper ring 1 is slidably connected to the inner wall of the filter element, a scraper ring 2 is slidably connected to the inner wall of the filter element, magnets are fixed inside the scraper ring 1 and the scraper ring 2, and water spraying mechanisms are provided on the scraper ring 1 and the scraper ring 2.

The oil mist enters the filter element inside the demister body through the air inlet pipe for oil mist separation and filtration. The mist goes out from the air outlet pipe through the filter element. The oil flows to the bottom of the demister body through the filter element and flows out of the demister body through the oil outlet. The filter holes and inner and outer walls of the filter element are then rinsed through a water spray mechanism. After rinsing, the first scraper ring and the second scraper ring slide up and down on the inner and outer walls of the filter element to scrape off the oil and water adhered to the inner and outer walls of the filter element, so as to prevent the oil adsorbed on the inner and outer walls of the filter element from drying and blocking the filter holes of the filter element, thereby improving the service life of the demister body.

[0010] By adopting the above structure, by installing the lead screw and the guide rod, the motor is started to drive the lead screw to rotate, and the scraper ring 1 on the lead screw moves up and down on the inner wall of the filter element. The guide rod limits it, and the scraper ring 1 drives the scraper ring 2 on the outer wall of the filter element through the magnet to move together, so as to scrape off the oil adsorbed on the inner and outer walls of the filter element, thereby preventing the oil adsorbed on the inner and outer walls of the filter element from drying and blocking the filter holes of the filter element, thereby improving the service life of the demister body.

Then, the water pump is used to make the water spray pipe spray water to the inner and outer walls of the filter element. After spraying water, the lead screw is used to rotate and drive the scraper ring 1 and the scraper ring 2 to move up and down to scrape the water and oil on the inner and outer walls of the filter element, thereby making the oil adsorbed on the filter element cleaner and increasing the practical life of the demister body.

[0016] With the above structure, by installing gear one and gear two, the motor drives the lead screw to rotate while the gear one and gear two drive the rotating column to rotate, so that the rotating column drives the scraper to rotate at the bottom of the filter element, and the oil at the bottom of the filter element is cleaned to prevent the filter hole at the bottom from being blocked and the oil from not flowing down.

[0017] Compared with the existing technology, this lubricating oil station tank demister has the following advantages:

[0018] 1. Connect the air inlet pipe to the oil tank of the lubricating oil station, start the fan, and the oil mist enters the filter element inside the demister body through the air inlet pipe for oil mist separation and filtration. The mist goes out from the air outlet pipe through the filter element, and the oil flows to the bottom of the demister body through the filter element and flows out of the demister body through the oil outlet. The filter holes and inner and outer walls of the filter element are then rinsed through the water spray mechanism. After rinsing, the scraper rings 1 and 2 slide up and down on the inner and outer walls of the filter element to scrape off the oil and water adhering to the inner and outer walls of the filter element to prevent the oil adsorbed on the inner and outer walls of the filter element from drying and blocking the filter holes of the filter element, thereby increasing the service life of the demister body.

[0019] 2. By installing the water spray pipe, when the scraper ring 1 and the scraper ring 2 slide to the uppermost end of the filter element, the two water pipes on the water tank are respectively inserted into the water injection holes on the scraper ring 1 and the scraper ring 2, and the scraper ring 1 and the scraper ring 2 are filled with water, and then the water is sprayed on the inner and outer walls of the filter element through the water spray pipe. After spraying the water, the scraper ring 1 and the scraper ring 2 are driven up and down by the screw to scrape the water and oil on the inner and outer walls of the filter element, so that the oil adsorbed on the filter element can be cleaned more cleanly and the practical life of the demister body is increased.
