Description
Technical field
The utility model belongs to the filter element field, relates in particular to a kind of column type Stainless Steel fiber sintering felt serving and crosses filter core.
Background technology
Cross filter core and be mainly used in impurity in the filtering liquid medium.At present, this type of filter element relies on import substantially, its buying price height, and procurement cycle is long, installation and maintenance inconvenience.In addition, from user mode, existing product remains in characteristics such as filter core body intensity are low excessively, and filtering layer easily comes off, and permeance property is poor, and service life is short.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, crosses filter core body intensity height, the filtering layer difficult drop-off, and good filtration effect, the column type Stainless Steel fiber sintering felt serving of long service life is crossed filter core.
For achieving the above object, the utility model is achieved in that
A kind of column type Stainless Steel fiber sintering felt serving is crossed filter core, it comprise interior stay pipe, with described in the filtering layer that fixedly connects of stay pipe outer wall, the connecting thread that fixedly connects with the end of described interior stay pipe; The outer wall of stay pipe is provided with cellular through hole in described; The central passage of stay pipe is through cellular through hole and filtering layer and exterior in described; Stay pipe in described; The other end fixedly be furnished with the location cone.
As a kind of preferred version, filtering layer described in the utility model comprises protective layer, key-course, shunting layer, first enhancement Layer and second enhancement Layer; Described protective layer, key-course, shunting layer, first enhancement Layer and second enhancement Layer all adopt the Stainless Steel screen net structure, and are sintered into one successively.
As another kind of preferred version, filtering layer described in the utility model can adopt wave structure.
As the third preferred version, the utility model fixedly is furnished with the direct fluid cone in an end of stay pipe central passage in described; The bottom surface of described direct fluid cone is affixed with the bottom surface of location cone.
Connecting thread described in the utility model can adopt interior hexagonal screw thread.
The utility model is simple in structure, crosses filter core body intensity height, filtering layer difficult drop-off, good filtration effect, long service life.In cleaning process, the filter core structure intensity stabilization can not cause the generation of the modification phenomenon of being heated.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Protection domain of the present utility model will not only be confined to the statement of following content.
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, a kind of column type Stainless Steel fiber sintering felt serving is crossed filter core, it comprise interior stay pipe 1, with described in the filtering layer 4 that fixedly connects of stay pipe 1 outer wall, the connecting thread 2 that fixedly connects with the end of described interior stay pipe 1; The outer wall of stay pipe 1 is provided with cellular through hole 3 in described; The central passage 5 of stay pipe 1 is through cellular through hole 3 and filtering layer 4 and exterior in described; The other end of stay pipe 1 fixedly is furnished with location cone 11 in described; Described filtering layer 4 comprises protective layer 6, key-course 7, shunting layer 8, first enhancement Layer 9 and second enhancement Layer 10; Described protective layer 6, key-course 7, shunting layer 8, first enhancement Layer 9 and second enhancement Layer 10 all adopt the Stainless Steel screen net structure, and are sintered into one successively; Filtering layer 4 described in the utility model adopts wave structure; An end of stay pipe 1 central passage fixedly is furnished with direct fluid cone 12 in described; The bottom surface of described direct fluid cone 12 is affixed with the bottom surface of location cone 11; Described connecting thread 2 is interior hexagonal screw thread.From fluid-mechanics point of view, in 12 pairs of the direct fluid cones in stay pipe 1 central passage flowing liquid medium play guide effect.For improving installation accuracy of the present utility model, location cone 11 can be calibrated the location to the utility model.
The utility model Stainless Steel fiber sintering filter felt is the porous degree of depth type filtering material that a kind of Stainless Steel fiber is made through high temperature sintering.Characteristics such as corrugated is crossed filter core and had the porosity height, and filter area is big, and water environment capacity is strong, and reusability is strong.The utility model is crossed filter core master filtering material Stainless Steel fiber sintering filter felt and is adopted five layers of stainless steel cloth sintering structure, and filtering accuracy is 0.5～200 μ m.Five layers of sintering net are to be formed by five layers of stainless steel cloth vacuum-sintering.
The utility model is crossed filter core with one group of column type Stainless Steel fiber sintering felt serving and is connected on the tube sheet by connecting thread in use, tube sheet is inserted in the filtering container seal.Liquid medium to be filtered enters column type Stainless Steel fiber sintering felt serving from an end of filtering container and crosses the filter core, and after filtering through the utility model, liquid medium is drawn from the other end of filtering container again.Along with increasing of impurity screening, the inlet and outlet pressure missionary society of filtering container increases gradually, when pressure differential reaches certain value, column type Stainless Steel fiber sintering felt serving should be crossed filter core and disassemble and clean, so that make its repeated use.
