Abstract
The utility model discloses an inner core for a filter element component. The inner core for the filter element component comprises a cylindrical framework; the upper end of the framework is buckled with an upper cover; the lower end of the framework is buckled with a lower cover; a non-woven fabric layer is sleeved outside the framework; the upper edge of the non-woven fabric layer is fixed with the upper cover through the framework; the lower edge of the non-woven fabric layer is fixed with the lower cover through the framework; all of the framework, the upper cover and the lower cover are of plastic injection molding structures. The inner core for the filter element component is simple in structure and low in manufacturing cost; the original iron filter net is replaced by the plastic framework, so that not only can the cost be reduced, but also rust can be prevented, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of inner core of element kit.
Background technology
At present, reciprocating machine (internal combustion engine, reciprocating compressor etc.) when work, just will aggravate the wearing and tearing of part if contain the impurity such as dust in air amount, so air filter must be housed.The chief component of air filter is filter core and casing, and wherein filter core is main filtration fraction, is bearing the filtration work of gas.Common inner core, by irony filter screen welding fabrication, uses heavier and easily corrosion in a humid environment, affects filter efficiency and filter element life.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of inner core of element kit is provided, good filtration effect, and cost is lower.
For achieving the above object, the technical solution of the utility model has been to provide a kind of inner core of element kit, comprise cylindrical circular skeleton, the upper end of described skeleton is snapped with upper cover, the bottom of described skeleton is snapped with lower cover, described skeleton is arranged with nonwoven layer outward, the top edge of described nonwoven layer is fixed by described skeleton and described upper cover, the lower limb of described nonwoven layer is fixed by described skeleton and described lower cover, and described skeleton, described upper cover, described lower cover are the injection molding structure.
As preferably, described skeleton is grid-like.
As preferably, described skeleton circumferentially is provided with some reinforcement raised lines along it.
As preferably, cover on described and offer the upper slot of annular, the upper end of described skeleton has the upper Plug Division of annular, matches with described upper slot in described upper Plug Division, the upper edge of described nonwoven layer on described Plug Division and described between slot; Cover under described and offer the lower slot of annular, the bottom of described skeleton has annular lower inlaying grafting part, described lower inlaying grafting part matches with described lower slot, and the lower edge portion of described nonwoven layer is between described lower inlaying grafting part and described lower slot.
Advantage of the present utility model and beneficial effect are: simple in structure, manufacturing cost is lower, and replaces original irony filter screen by plastic skeleton, not only can reduce costs, and can prevent from getting rusty, and increases the service life.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, skeleton; 2, upper cover; 3, lower cover; 4, nonwoven layer; 5, strengthen raised line.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Shown in Fig. 1, a kind of inner core of element kit, comprise cylindrical circular skeleton 1, the upper end of described skeleton 1 is snapped with upper cover 2, the bottom of described skeleton 1 is snapped with lower cover 3, the outer nonwoven layer 4 that is arranged with of described skeleton 1, the top edge of described nonwoven layer 4 is fixing with described upper cover 2 by described skeleton 1, the lower limb of described nonwoven layer 4 is fixing with described lower cover 3 by described skeleton 1, described skeleton 1, described upper cover 2, described lower cover 3 are the injection molding structure, and described skeleton 1 is grid-like.
Shown in Fig. 1, described skeleton 1 circumferentially is provided with some reinforcement raised lines 5 along it.
Shown in Fig. 1, offer the upper slot of annular on described upper cover 2, the upper end of described skeleton 1 has the upper Plug Division of annular, matches with described upper slot in described upper Plug Division, the upper edge of described nonwoven layer 4 on described Plug Division and described between slot; Offer the lower slot of annular on described lower cover 3, the bottom of described skeleton 1 has annular lower inlaying grafting part, described lower inlaying grafting part matches with described lower slot, and the lower edge portion of described nonwoven layer 4 is between described lower inlaying grafting part and described lower slot.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
