Description
Technical Field
The invention relates to a silencing and degreasing filter element, in particular to a silencing and degreasing filter element for an oil collecting type silencer.
Background
Along with the popularization and execution of the related mechanical pressure safety standard EN692 mechanical press safety and GB27607 mechanical press safety technical requirements and the strengthening of the national environmental protection and labor protection policies, the prior compressed air with oil mist in the clutch discharged from the exhaust port of the mechanical pressure safety double-valve pollutes the environment (the surroundings) and the generated oily aerosol is harmful to human bodies. Solving the problems is unprecedented.
Both taiwan Jinfeng machine Co., ltd and Jinfeng (China) precision machinery Co., ltd use the AMC series of exhaust cleaners of the Japanese SMC. When the oily compressed air discharged from the exhaust port of the safety double-connected valve enters an AMC (exhaust cleaner) oil collecting silencer, the oily compressed air enters a super-oleophobic composite oil removing filter element after being damped and decelerated by a paper silencing piece, and is diffused and silenced, the oily compressed air in the super-oleophobic composite oil removing filter element forms tiny vortex air flow to accelerate again so that water and oil gas in the oily compressed air are separated from the oily compressed air to drop down, and the drops enter an oil collecting cup. The super-oleophobic composite oil removal filter element is a foaming silk screen with the surface coated with super-oleophobic and water films, so that separated oil drops can not adhere to the inner surface of the super-oleophobic composite oil removal filter element and drop down.
The oil collecting type muffler solves the problems of oil mist separation and oil mist centralized recovery, but the paper muffler belongs to a labyrinth gluing type muffler structure, and the muffler is very easy to be blocked after working for a period of time, and does not meet the related requirements of GB27607 on the safety muffler; further, the specification of the use of the japanese SMC-related AMC (exhaust gas cleaner) oil collecting muffler has been clarified.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the silencing and degreasing filter element disclosed by the invention comprises a filter element body 1, wherein a silencer upper cover 2 is arranged at the upper end of the filter element body 1, an air inlet is arranged on the silencer upper cover 2, a silencer bottom cover 3 is arranged at the lower end of the filter element body 1, the filter element body 1 is formed by winding a coarse screen 4 and a fine screen 5, the coarse screen 4 and the fine screen 5 are arranged at intervals, the coarse screen 4 and the fine screen 5 are made of nylon 66, the mesh number of the coarse screen 4 is about 80# and the mesh number of the fine screen 5 is about 120#, oil-water separation films are sprayed on two side surfaces of the coarse screen 4, the oil-water separation films are not sticky and water-sticky, and the oil-water separation films can be made of super-hydrophobic paint sold in the market; an inner retainer 6 and an outer retainer 7 are respectively arranged on the inner side and the outer side of the filter element body 1, an inner retainer vent hole 8 is formed in the inner retainer 6, the inner retainer vent hole 8 is used for enabling oil-containing compressed air to enter the filter element body 1 from the inner cavity of the silencing and degreasing filter element to be subjected to oil mist separation and noise reduction, an outer retainer vent hole 9 is formed in the outer retainer 7, and the outer retainer vent hole 9 is used for discharging the compressed air subjected to degreasing and noise reduction through the filter element body 1 to the outer side of the silencing and degreasing filter element; and oil drop release holes 10 are respectively arranged on the silencer bottom cover 3 at the bottom of the inner cavity of the silencing and degreasing filter element and the silencer bottom cover 3 at the bottom of the filter element body 1, and the oil drop release holes 10 are used for enabling separated oil mist to flow out of the filter element.
The working principle of the silencing and degreasing filter element is shown in figure 2, the spiral accelerating airflow containing oil is accelerated when passing through small air holes uniformly distributed on the fine screen 5, and then the airflow is diffused to form a plurality of low-pressure areas after passing through the small air holes, because the outward discharge of the airflow containing oil is an adiabatic process, namely, the airflow containing oil takes away a large amount of heat when the airflow containing oil is discharged outwards, the temperature of the airflow containing oil is reduced in the low-pressure areas, oil drops and water drops are separated after the saturation of the airflow containing oil and water is reduced, and because the interlayer is a coarse screen 4 and the surface of the coarse screen 4 is sprayed with an oil-water separation film, the separated oil drops and water drops can not hang on the coarse screen and drop down, and thus the airflow containing oil and water is filtered layer by layer and separated until clean air is separated. In addition, the filter element body 1 formed by winding the two kinds of screens with different mesh numbers of the coarse screen 4 and the fine screen 5 is adopted, when compressed air discharged from the safety duplex network passes through the small holes of the first layer of screens, the air flow speed is weakened by the small holes and the interlayer damping effect, namely, when compressed air containing oil and water with high decibel discharged from the safety duplex valve passes through the filter element body, the oil and water can be effectively separated, the noise during discharging can be reduced from 100Mb to below 75Mb, in addition, because the size of the small holes of each layer of screens is changed, a plurality of granular impurities are very difficult to adsorb on the screens and fall along with oil and water drops after the oil-water separation film is sprayed on the surface of the coarse screen, and therefore, the silencing and oil-removing filter element is used on a safety oil-collecting silencer and is considered to be intrinsically safe because the noise is not blocked.
