Abstract
The utility model relates to a filter. The filter comprises a housing and a filter component, wherein the filter component comprises an upper filter screen, a filter material and a lower filter screen; the upper filter screen and the lower filter screen are respectively arranged on the upper surface and the lower surface of the filter material; and the housing is made of polyurethane resin adhesive and wrapped on the periphery of the filter component. According to the filter disclosed by the utility model, the housing does not need to be produced independently, and the housing is formed by directly solidifying the liquid-state polyurethane resin adhesive in a mold for producing the filter; and simultaneously, the connection between the housing and the filter component is firm, stable and less prone to shedding. According to the scheme disclosed by the utility model, a net sling is further arranged on the upper surface of the upper filter screen so as to facilitate lifting and taking of the whole filter; and the structure is simple and practical.
Description
Technical field
The utility model relates to a kind of filter, and a kind of improvement of filter of filtered air is provided especially, belongs to air filtration equipment technical field.
Background technology
At present, air cleaner commonly used such as the filter of the usefulness such as dust catcher, comprises housing, filter assemblies; Described housing hollow; Bonding or the supersonic welding all around of described filter assemblies is connected on the sidewall of housing hollow space; Described filter assemblies comprises screen pack, filtering material, lower screen pack; Described upper screen pack, lower screen pack are separately positioned on upper surface, the lower surface of filtering material; The filter of this structure, described housing are plastics or rubber parts, need separately processing; Then just or supersonic welding bonding with filter assemblies is connected together because the restriction of product structure and processing technology, filter in use, filter assemblies easily and housing generating portion or all come off causes filter failure.
The utility model content
The utility model purpose is to have proposed a kind of filter assemblies to be connected closely the filter of difficult drop-off with housing in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of filter comprises housing, filter assemblies; Described filter assemblies comprises screen pack, filtering material, lower screen pack; Described upper screen pack, lower screen pack are separately positioned on upper surface, the lower surface of filtering material; Described housing is made by polyurethane resin glue, is wrapped in the periphery of filter assemblies.
Preferably, the upper surface of described upper screen pack is provided with the string bag, conveniently to lift.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Filter described in the utility model, described housing is not produced separately, and described housing adopts liquid polyurethane resin glue directly to solidify in the mould of producing filter and forms, and simultaneously, described housing is fastening with being connected of filter assemblies, stable, difficult drop-off; The utility model scheme also is provided with the string bag at the upper surface of upper screen pack, conveniently lifts whole filter, and is simple in structure, practicality.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of a preferential embodiment of filter described in the utility model;
Accompanying drawing 2 is the cutaway view of accompanying drawing 1;
Wherein: 1, shell; 2, upper screen pack; 3, the string bag; 4, filtering material; 5, lower screen pack.
The specific embodiment
Be depicted as a kind of filter of the present utility model such as accompanying drawing 1,2, comprise housing 1, filter assemblies; Described filter assemblies comprises screen pack 2, filtering material 4, lower screen pack 5; Described upper screen pack 2, lower screen pack 5 are separately positioned on upper surface, the lower surface of filtering material 4; Described housing 1 is made by polyurethane resin glue, is wrapped in the periphery of filter assemblies.The upper surface of described upper screen pack 2 is provided with the string bag 3, conveniently to lift.The product that described polyurethane resin glue adopts Suzhou chemical company to produce, in the production process, first filter assemblies is positioned in the mould of producing filter, then allow mould rotate with certain speed, again with the polyurethane resin glue encapsulating of liquid state in the space of mould, the polyurethane resin glue cooled and solidified of relief liquid state is namely made filter described in the utility model.
The filter of the utility model scheme is not limited to circular filter, and the filter of other various shapes is also within the utility model scheme.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Filter described in the utility model, described housing is not produced separately, and described housing adopts liquid polyurethane resin glue directly to solidify in the mould of producing filter and forms, and simultaneously, described housing is fastening with being connected of filter assemblies, stable, difficult drop-off; The utility model scheme also is provided with the string bag at the upper surface of upper screen pack, conveniently lifts whole filter, and is simple in structure, practicality.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
