as shown in fig. 5 and 6, the supporting plate 102 includes a fixing ring 1021 on the outer circle, a plurality of clamp rings 1022, and a connecting rod 1023 for fixedly connecting the clamp rings 1022 and the fixing ring 1021, and connecting the clamp rings 1022 and the clamp rings 1022 located at the center; the compression rings 1022 are uniformly distributed along the circumference of the fixing ring 1021; a filter element slide way 1024 is arranged on the compression ring 1022;
the supporting plate 102 is fixed with the inner wall of the shell 1; the pressure plate 91 and the oil filter support 93 are both detachably connected with the inner wall of the shell 1.
The distance between the oil filtering component 9 and the air filtering component 10 is more than 1-1.5 times of the length of the filter element 1011 or less than 300mm.
The working principle of the invention is as follows: the filtering materials such as filter cotton, active carbon, filter paper and the like are utilized to effectively intercept oil, moisture, solid particles and other impurities in the air so as to achieve the purpose of primary filtering of the gas. Air enters the main air filter shell 1 through a pipeline, oil entrained by the air is intercepted through the oil filtering assembly 9, and large particle substances in the air can be effectively intercepted through the air filtering assembly 10, so that the purpose of primary filtration is achieved. The oil filter layer 92 of the oil filter assembly 9 and the filter element 104 of the air filter assembly 10 can be replaced through the manhole 7.
Since the filter belongs to a pressure vessel, it can withstand a large air pressure, for a large diameter (diameter)>1000 mm), if change the internal component need use the barrel flange, and need use large-scale equipment such as fork truck, overhead traveling crane when dismantling the barrel flange, receive the influence of on-the-spot workspace simultaneously, therefore in order to avoid dismantling the renew cartridge inconvenience, it is relatively reasonable to use pressure vessel accessories such as manhole 7 that the compressive ratio is stronger. When the filter element is replaced, in order to facilitate the operation of people entering the manhole, the oil filter layer 92 of the oil filter assembly 9 needs to be taken out, and the distance between the oil filter assembly 9 and the gas filter assembly 10 needs to be controlled, preferably the distance between the oil filter assembly 9 and the gas filter assembly 10 is controlled<300mm or>1~1.5L Filter element (L represents the length), so that the filter element can smoothly enter the slide way of the filter element of the air filtering component by means of the gap supported by the oil filtering of the oil filtering component, or the distance between the oil filtering component 9 and the air filtering component 10 is more than 1-1.5 times of the length of the filter element, thereby facilitating the filter element to vertically enter the slide way of the filter element.
The use method of the invention comprises the following steps:
the gas enters from a, passes through the gas inlet flange 4 and the gas inlet pipe 2 and is transited to the shell 1, the gas is gradually buffered towards the oil filter assembly 9, oil in the gas can be removed through an oil filter layer 92 of the oil filter assembly 9, and the oil filter layer is fixed through a pressure rod 91 and an oil filter support 93. The primary filtered oil is passed gradually through the air filter assembly 10, the core component of the air filter assembly 10 is a filter element assembly 101, a plurality of filter element assemblies 101 can be fixed by two support plates 102, and each filter element can be fixed by a hanger plate 1012 and a pull rod 1013. The gas passing through the gas filtering component 10 basically meets the requirement of primary filtering, and the interception rate of solid particles of more than 0.5um can be 99.5%. Then the gas is discharged out of the filter through the gas outlet connecting pipe 3 and the gas outlet flange 5, and then enters other equipment.
In this filter, the arrangement of the filter element assembly 101 and the positions of the oil filter support 93 and the support plate 102 need to be particularly careful, both in consideration of the convenience of filter element replacement and the strength requirements. Therefore, for the total air filter with 9 filter elements arranged, in order to enable the filter elements to smoothly pass through the gap of the oil filter assembly and enter the filter element slide way, the spatial positions of the oil filter support and the filter elements need to be reasonably arranged, so that the oil filter support is firm, and the filter elements can conveniently pass through, wherein one of the arrangement modes is as shown in fig. 6.
