Abstract
The utility model discloses a kind of sewing structure of PO PE NT PTFE mouth, the two panels needle felt material seamless tiled splicing of filter pocket mouths, and splicing mouth uplink and downlink intersects sewing connection.The boundary of needle felt material is straight line, and straight line splicing, which avoids the occurrence of notch, causes the dust in bag to leak out.The utility model has the advantages that the dust in bag is avoided to leak out, dust collection rate is significantly improved.
Description
Technical field
The utility model relates to a kind of sewing field of thick felt, in particular to a kind of sewing structures of PO PE NT PTFE mouth.
Background technique
The sewing of needled conventionally felt filter sack is to be overlapped upper and lower two panels, a plurality of straight line sewing is carried out in place of overlapping, directly
Sewer line 3 is as shown in Figure 1.But needle felt material is very thick, in upper and lower two panels overlapping, there are still apparent notches, suitable
With cement industry gather dust operating condition when apparent dust can occur leak grey phenomenon.This is that the application needs place improved emphatically.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of PO PE NT PTFE mouth for improving dust collecting rate
Sewing structure.
For the technical problem more than solving, the utility model provides a kind of sewing structure of PO PE NT PTFE mouth, filters
The two panels needle felt material seamless tiled of sack is spliced, and splicing mouth uplink and downlink intersects sewing connection.The boundary of needle felt material is
Straight line, straight line splicing avoids the occurrence of notch as far as possible causes the dust in bag to leak out.
The splicing mouth sewing place covers a masked film, further avoids splicing mouth and a possibility that leakage ash occurs.
Superior effect of the utility model is: the utility model changes the splicing of certain thickness needle felt material
Mode avoids the dust in bag from leaking out, significantly improves dust collection rate, reduces the influence to ambient enviroment.
Detailed description of the invention
The accompanying drawings constituting a part of this application is used to provide a further understanding of the present invention, this is practical
Novel illustrative embodiments and their description are not constituteed improper limits to the present invention for explaining the utility model.
In the accompanying drawings:
Fig. 1 is the structural schematic diagram that the filter pocket mouths of needled conventionally felt sew；
Fig. 2 is the structural schematic diagram that the filter pocket mouths of the utility model Nomex sew；
Figure label explanation:
1-needle felt material A；2-needle felt material B；
3-straight line sewing lines；4-intersect sewing line.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing.
Fig. 2 shows the schematic diagrames of the utility model embodiment.As shown in Fig. 2, the utility model provides a kind of needle thorn
The sewing structure of felt filter sack, the linear edge seamless tiled splicing of the needle felt material A1 and needle felt material B2 of filter pocket mouths,
It spells the sewing of interface uplink and downlink and intersects sewing line 4.
In order to further increase dust collection rate, it is coated with a glue-line in splicing mouth sewing place, further avoids the possibility of leakage ash
Property.
The utility model changes the splicing construction of thick material, is intersected using diagonal and is sewed, and is suitable for cement industry and receives
Improve significantly effect when dirt operating condition.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included in the protection scope of the utility model.
