Abstract
An apparatus for filtering petroleum blue gas comprises a gas-in interface at the top part of an upper cover, a diversion cap at the lower part of a gas inlet of the upper cover, a filter core installed in a lower casing at the lower part of the diversion cap, and a gas outlet arranged at the lower end of the lower casing. The filter is composed of filtering layers A and filtering layers B. The filtering layers An are cotton filtering layers, arranged at the gas inlet and the gas outlet ends. The filtering layers B are natural original wood filtering layers,arranged among the filtering layers A. The diversion cap is opened with a plurality of small holes. The utility model has the advantages of effective absorption of the water, the oil and the impurity ingredient contained in the petroleum liquid gas, good permeability, high filtration efficiency, simple and reliable structure, convenient change for the filter core and long service life.
Description
Technical field:
The utility model relates to a kind of oil liquefied gas filter, and particularly a kind of being applicable to the oil liquefied gas is the oil liquefied gas filter that the power assist vehicle of fuel is used.
Background technology:
Existing in the market is that the oil liquefied gas filter of the power assist vehicle of fuel generally all adopts wire netting to add filter paper to filter oil liquefied gas with the liquefied petroleum gas, and contain certain water in the oil liquefied gas that uses at present, oil, impurity, when running into the water that contains in the oil liquefied gas, filter paper can be out of shape, damaged, can influence the gas permeability of filter when running into contain in the oil liquefied gas oily, the employing non-woven cotton is also arranged, chemical fibre cotton, wire netting and powder metallurgy etc. are as filter core, but because the water that contains in the oil liquefied gas, oil, impurity, and these worry cores itself do not possess suction, oil suction, ventilative function, thereby make that oil liquefied gas filter filter effect is undesirable, consider core stage of replacement weak point, cause the maintenance rate height.The purpose of this utility model is exactly in order to address the above problem, and designs a kind of novel oil liquefied gas filter.
Summary of the invention:
Formation of the present utility model mainly comprises: intake interface, loam cake, O-ring seals, fairing cap, filter core, lower casing, the interface of giving vent to anger, air inlet is positioned at tops, last tops air inlet is provided with internal thread and matches with the external screw thread of intake interface, fairing cap is positioned at loam cake air inlet bottom, filter core is installed in the lower casing of fairing cap bottom, the lower casing lower end is located in the gas outlet, this gas outlet is provided with internal thread and matches with the external screw thread of escape pipe interface, it is characterized in that: described filter core is made up of filter course A and filter course B, filter course A is the cotton filter course, be located at air inlet and gas outlet end, filter course B is that natural wood matter filter course is located between the filter course A, has many apertures on the fairing cap.The utility model has the advantages that: this oil liquefied gas filter can effectively absorb water, oil, the impurity composition that contains in the oil liquefied gas, good permeability, and the filter efficiency height, simple and reliable for structure, more renew cartridge is convenient, and life cycle is long.
Description of drawings:
Fig. 1 the utility model structural representation;
The structural representation of another embodiment of Fig. 2 the utility model.
Interface, 10 bolts, 6-1 filter course A, 6-2 filtering layer B give vent to anger for 1 intake interface, 2 air inlets, 3 loam cakes, 4 sealing rings, 5 fairing caps, 6 filter cores, 7 lower casings, 8 gas outlets, 9.
The specific embodiment:
Embodiment one:
5. intake interface 1, the interface 9 of giving vent to anger are an outside and have externally threaded through hole, loam cake 3 top air inlets 2 are provided with internal thread and match with the external screw thread of intake interface 1, fairing cap 5 is installed on the bottom of loam cake air inlet 2, have many apertures on the fairing cap 5, when the many aperture of the oil liquefied gas that is filtered by fairing cap 5, can make gas form eddy flow, thereby make gas produce spray pattern, so that filter core 6 fully filters.Filter core 6 is installed in the lower casing 7 of fairing cap 5 bottoms, described filter core 6 is made up of filter course A6-1 and filter course B6-2, filter course A6-1 is the cotton filter course, be located at fairing cap 5 bottoms of air inlet 2,9 mouth end also is provided with filter course A6-1 in the gas outlet, and filter course B6-2 is that natural wood matter filter course is located between the filter course A6-1 and is filled in the lower casing 7.Filter course A6-1 is the cotton filter course, to improve the service life of the filter course B6-2 that natural wood is processed into.Filter course B6-2 has air permeability and good and very strong suction, oil absorbency under normal pressure, after the oil liquefied gas that is filtered passed through filter course B6-2, the water in the oil liquefied gas, oil, impurity were attracted in the filtering layer B6-2.The filter course A6-1 of 9 mouth end D plays twice suction-operated in the gas outlet, and cushions gas sinuous flow.Gas outlet, lower casing 7 bottom 8 is provided with internal thread and matches with the external screw thread of the interface 9 of giving vent to anger.O-ring seals 5 plays the sealing function of loam cake and lower casing between loam cake 3 and lower casing 7.Loam cake 3 is fastening by bolt 10 with lower casing 7.One O-ring seals 4 is between loam cake 3 and lower casing 7, and loam cake 3 is fastening by bolt 10 with lower casing 7.
Embodiment two
Identical with embodiment one, different is that filter course B6-2 makes sheet and filter course A6-1 makes up apart from one another by being provided with to interlock, and in fairing cap 5 lower ends of air inlet 2 filtering layer A6-1 is set, and the 8 mouthfuls of ends in gas outlet also are provided with filtering layer A6-1.
Claims (4)
1. oil liquefied gas filter, mainly comprise: intake interface, loam cake, O-ring seals, fairing cap, filter core, lower casing, the interface of giving vent to anger, air inlet is positioned at tops, last tops air inlet is provided with internal thread and matches with the external screw thread of intake interface, fairing cap is positioned at loam cake air inlet bottom, filter core is installed in the lower casing of fairing cap bottom, the lower casing lower end is located in the gas outlet, this gas outlet is provided with internal thread and matches with the external screw thread of escape pipe interface, it is characterized in that: described filter core is made up of filter course A and filter course B, filter course A is the cotton filter course, be located at air inlet and gas outlet end, filter course B is that natural wood matter filter course is located between the filter course A, has many apertures on the fairing cap.
