Abstract
The utility model discloses parallel-connection prefilters. Each prefilter comprises a liquid inlet, an air outlet, a cylinder cover, a cylinder body, a filtering board, a baffle, a filtering cartridge and a liquid outlet, wherein the baffle is in an elliptical ring shape, is placed on the middle part of the cylinder body and is slantways arranged on a horizontal plane in an angle of 45 degrees; the edges of the baffle are in closely contact with the inner surface of the cylinder body; the filtering board is elliptic; the filtering board and the baffle are parallelly put on the baffle; the filtering cartridge which is coaxial with the cylinder body is in a cylinder shape; the top of the filtering cartridge is in an ellipse shape matched with the middle ring shape of the baffle and is embedded in the lower part of the baffle. The prefilter is simple in integral structure, and convenient and reliable to run; the filtering board is arranged on the horizontal plane in the angle of 45 degrees, so that the filtering area is increased, and the filtering speed is improved; the filtering cartridge is embedded in the lower part of the baffle and is used for secondary filtering of liquid, so that the filtering area is increased, and the filtering speed and the filtering effect are improved; according to the actual requirements of users, different filtering styles can be switched, under the condition of meeting the requirements of the users, the cost is furthest saved, so that the parallel-connection prefilters have very good market use value.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of for removing oarse-grained prefilter in parallel.
Background technology
Prefilter mainly uses at refinery and airfield POL storage, as the protectiveness fore filter of fine filter, coalescing separator, flowmeter, control valve etc.In the serious occasion of particle contamination, be arranged on coalescing separator before, can effectively extend service life of Coalescence filter core, greatly save production cost.Be arranged on while using before flowmeter, control valve, can effectively prevent that machinery is stuck, prefilter all can use in the processing of gas and liquid medium and course of conveying.The profile of prefilter is substantially similar with coalescer profile, belongs to online sports equipment.The import and export of medium are determined according to the diameter of place systematic pipeline.
Existing prefilter adopts the filter of parallel placement to filter mostly, and device interior filtering surface is narrow, causes filter liquide speed slower, and filter effect is not good, has affected the Whole Equipment speed of service and filter quality.
Utility model content
The purpose of this utility model is: a kind of prefilter is provided, and simple in structure, filter area is large, the rate of filtration is fast, good filtration effect; And can be according to user's actual need, switch different filter types, reached best filter effect.
The technical solution of the utility model is: a kind of prefilter in parallel, it is characterized in that being provided with a pair of prefilter by pipeline parallel connection, and every prefilter comprises inlet, steam vent, cover, cylindrical shell, filter, baffle plate, cartridge filter and liquid outlet; Described cylindrical shell is cylindrical; Cover is positioned at cylindrical shell top and built-in steam vent, as top cover of cylinder body; Described inlet is positioned at cylindrical shell top one side; Described liquid outlet is positioned at cylindrical shell bottom one side; Described baffle plate is oval ring, is positioned at cylindrical shell middle part, become miter angle slant setting, and outward flange is near cylinder inner surface with horizontal plane; Described filter is oval, is placed in parallel on baffle plate with baffle plate; Described cartridge filter is the cylindrical shape coaxial with cylindrical shell, and top is the ellipse matching with baffle plate intermediate annular, the nested baffle plate bottom that is positioned over.
Further, the orthographic projection diameter of a circle of described filter is greater than the orthographic projection circular diameter of baffle plate adapter ring, is less than cylindrical shell interior diameter.
Further, described cover bottom vertical is fixed with two fixed bars, and one section of fixed bar is connected with top cover, and one end is connected with baffle plate, for the position of fixed dam.
The beneficial effects of the utility model are: 1, equipment overall structure simple, move convenient and reliable; 2, filter becomes miter angle slant setting with horizontal plane, has increased filter area, has improved the rate of filtration; 3, baffle plate bottom nested is placed cartridge filter, and liquid is carried out to secondary filter, has increased filter area, has improved the rate of filtration and filter effect; 4, can be according to user's actual need, selection filter filters separately, cartridge filter filtration or filter and cartridge filter combined filtering separately, in the situation that meeting consumers' demand, cost-saving to greatest extent, has fabulous market value.
Accompanying drawing explanation
Fig. 1 is the structural representation of prefilter.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
Prefilter as shown in Figure 1, comprises inlet 1, steam vent 2, cover 3, cylindrical shell 4, filter 5, baffle plate 6, cartridge filter 7 and liquid outlet 8; Described cylindrical shell 4 is cylindrical; Cover 3 is positioned at cylindrical shell 4 tops and built-in steam vent 2, as cylindrical shell 4 top covers; Described inlet 1 is positioned at cylindrical shell 4 top one sides; Described liquid outlet 8 is positioned at cylindrical shell 4 bottom one sides; Described baffle plate 6 is oval ring, is positioned at cylindrical shell 4 middle parts, becomes miter angle slant setting with horizontal plane, and outward flange is near cylindrical shell 4 inner surfaces; Described filter 5 is oval, is placed in parallel on baffle plate 6 with baffle plate 6; Described cartridge filter 7 is the cylindrical shape coaxial with cylindrical shell 4, and top is the ellipse matching with baffle plate 6 intermediate annular, nested baffle plate 6 bottoms that are positioned over.The orthographic projection diameter of a circle of described filter 5 is greater than the orthographic projection circular diameter of baffle plate 6 adapter rings, is less than cylindrical shell 4 interior diameters.Described cover 3 bottom vertical are fixed with two fixed bars, and one section of fixed bar is connected with top cover, and one end is connected with baffle plate 6, for the position of fixed dam 6.
The utility model equipment overall structure is simple, it is convenient and reliable to move.Filter becomes miter angle slant setting with horizontal plane, increased filter area, has improved the rate of filtration.Baffle plate bottom nested is placed cartridge filter, and liquid is carried out to secondary filter, has increased filter area, has improved the rate of filtration and filter effect.Meanwhile, can be according to user's actual need, selection filter filters separately, cartridge filter filtration or filter and cartridge filter combined filtering separately, in the situation that meeting consumers' demand, cost-saving to greatest extent, has fabulous market value.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
