Built-in large-flow filtering element

Abstract

The invention provides a built-in large-flow filtering element, which comprises an external filtering core and a built-in filtering core positioned in the external filtering core, wherein the externalfiltering core comprises a first outer skeleton, a first inner skeleton, a first filtering material positioned between the first outer skeleton and the first inner skeleton, and an outer upper end cover and an outer lower end cover connected to both ends of the first outer skeleton and the first inner skeleton, plugs are formed on the built-in filtering core, slots are formed on the outer lower end cover, and the plug is inserted and connected into the slot. According to the present invention, the built-in large-flow filtering element can be directly installed on the flower disk mouth of equipment, such that the connection is firm, and the practicability is strong; by connecting the built-in filtering core in the external filtering core, the first filtering material and the second filtering material can provide the filtration functions so as to increase the filtration area and prolong the service life; and the filtering element has characteristics of overall firmness, good sealing property and high filtration efficiency.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a built-in large flow filter element. Background technique [0002] The application of filtration technology is becoming more and more important both in industry and in civil use. Driven by the increasingly stringent national energy conservation and emission reduction policies, filtration technology has developed rapidly. Like air filtration, high efficiency, low resistance, large filtration area, and large flow are the constant pursuit of all filter element suppliers. The Chinese utility model patent with the authorized notification number CN204973133U discloses an integral filter element. There is only one folded filter material in the ROCKET. The filter area is small, the service life is short, the cost is high, and the purpose of energy saving and emission reduction cannot be achieved. [0003] In view of this, it is necessary to improve the filter elements in the pr...
