Description

Technical Field

[0001] This utility model relates to the field of filter screen technology, and in particular to an elliptical cylindrical filter screen fixing structure. Background Technology

[0002] A typical filter cartridge structure is set inside a filter cylinder. The fluid to be treated enters the filter cylinder from the outside, is filtered by the filter layer on the filter cartridge, and finally exits from the center of the filter cartridge. To ensure filtration efficiency, multiple filter cartridge structures are usually set inside the filter cylinder. In common filter cartridge structures, the filter cartridge is cylindrical, and multiple filter cartridges are arranged in an array inside the filter cylinder. However, using cylindrical filter cartridges in the limited space of the filter cylinder results in a low fill rate and poor filtration effect. In addition, with a cylindrical filter cartridge structure, the filtration surface is the same in the circumference, which can easily lead to insufficient filtration capacity on the flow-facing side and easy damage.

[0003] In addition, existing filter cartridges use an elliptical skeleton structure both inside and out. In the double elliptical structure, the unfolded cross section of the glass fiber filter layer of the filter element is a rectangular structure with no height difference, which easily leads to the corrugation and overlapping of the filter layer, resulting in fluid not being able to pass through or the filtration effect being reduced.

[0004] Later, a skeleton structure with an inner circle and an outer ellipse was developed. The filter layer of this structure is folded and unfolds with a height difference. On the one hand, the large flow-facing surface of the glass fiber filter layer serves as the flow-facing surface of the fluid, resulting in a smaller pressure difference, a larger dirt holding capacity, and a longer service life, which can effectively disperse fluid impact. On the other hand, due to the height difference of the glass fiber filter layer, the glass fiber filter layer cannot rotate between the skeleton modules, which avoids the compression and overlap of the corrugations, ensuring the fluid passage effect and filtration effect.

[0005] However, at the flow-facing side, the filter layer still shifts due to the impact of water flow and debris, affecting the filtration effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an elliptical cylindrical filter screen fixing structure, which can solve the problem that the inner circle and outer elliptical filter screen structure is easily displaced by water flow impact at the flow-facing position.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: an elliptical cylindrical filter screen fixing structure, the innovation of which is: including a skeleton module, a filter screen layer and a filter screen fixing module;

[0008] The skeleton module includes an outer skeleton and an inner skeleton; the outer skeleton is a column frame structure with an elliptical cross-section, and the inner skeleton is a column frame structure with a circular cross-section; the outer skeleton and the inner skeleton are both provided with mounting base plates along the vertical direction on the top and bottom outer walls and the top and bottom inner walls, for mounting the filter screen fixing module.

[0009] The filter layer is a corrugated structure formed by folding a single filter screen plane, with the crests and troughs of the folded filter screen plane placed on the inner surface of the outer frame and the outer surface of the inner frame, respectively. When the filter screen layer is unfolded in a folded shape and the troughs are located on the same plane, the height distribution of the crests in the horizontal direction forms a wave-like structure, creating a height difference. Connecting strips are provided at several folding positions at the top and bottom of the filter screen layer, and tensioning holes are opened on the connecting strips. The connecting strips bypass the top and bottom of the frame module and, through the filter screen fixing module and the tensioning holes on the connecting strips, tension the filter screen layer in the longitudinal direction.

[0010] The filter fixing module includes a hinged ear plate, a drive handle, a hook seat, and a locking hook. The hinged ear plate has a pair and is mounted on the surface of the mounting base near one end. The drive handle has a U-shaped structure and is hinged to the hinged ear plate by a pin. The hook seat has a cylindrical structure, and both ends are hinged to the drive handle by pins. The hook seat has a threaded through hole perpendicular to the axis. The locking hook includes a bent hook section and a screw section. The bent hook section is connected to one end of the screw section. The bent hook section engages with a tension hole on the connecting strip to tighten and fix the connecting strip on the filter layer. The other end of the screw section engages with the threaded through hole on the hook seat to install the locking hook on the hook seat. The locking hook can drive the hook seat to rotate around the drive handle.

[0011] Furthermore, one end of the connecting strip is sewn to the folded position of the filter layer.

[0012] The advantages of this utility model are:

[0013] 1) In this utility model, a folded corrugated filter screen layer is placed by using a skeleton structure with different inner and outer cross sections. By setting connecting strips at the top and bottom edges of the filter screen layer, the filter screen layer is tensioned and fixed in the vertical direction by the filter screen fixing module, so as to effectively fix the filter screen layer and prevent the filter screen layer from collapsing in the longitudinal direction due to the impact of water flow. This filter screen fixing structure greatly improves the stability and service life of the filter screen layer after installation. Attached Figure Description

[0021] like Figures 1 to 4 The elliptical cylindrical filter fixing structure shown includes a skeleton module 1, a filter layer 2, and a filter fixing module 3.

[0022] The skeleton module 1 includes an outer skeleton 11 and an inner skeleton 12; the outer skeleton 11 is a column frame structure with an elliptical cross section, and the inner skeleton 12 is a column frame structure with a circular cross section; the top and bottom outer walls of the outer skeleton 11 and the top and bottom inner walls of the inner skeleton 12 are both provided with mounting base plates 13 in the vertical direction for mounting the filter fixing module 3.

[0023] The filter layer 2 is a corrugated structure formed by folding a whole filter screen plane, and the crests and troughs formed by folding the filter screen plane are respectively placed on the inner surface of the outer frame 11 and the outer surface of the inner frame 12. When the filter layer 2 is unfolded in a folded shape and the troughs are located on the same plane, the height distribution of the crests in the horizontal direction is a wave-shaped structure, forming a height difference. The top and bottom ends of the filter layer 2 are provided with connecting strips 21 corresponding to several folding positions, and tensioning holes are opened on the connecting strips 21. The connecting strips 21 bypass the top and bottom ends of the frame module 1 and are used by the filter fixing module 3 in conjunction with the tensioning holes on the connecting strips 21 to achieve longitudinal tensioning of the filter layer 2.

[0024] The filter fixing module 3 includes a hinge ear plate 31, a drive handle 32, a hook seat 33, and a locking hook 34. The hinge ear plate 31 has a pair and is mounted on the surface of the mounting base plate 13 near one end.

The bent hook section cooperates with the tension hole on the connecting strip 21 to tighten and fix the connecting strip 21 on the filter layer 2. The other end of the screw section cooperates with the threaded through hole on the hook seat 33 to install the locking hook 34 on the hook seat 33. The locking hook 34 can drive the hook seat 33 to rotate around the drive handle.

[0025] One end of the connecting strip 21 is sewn to the fold position of the filter layer 2.

[0026] The working principle of this utility model is as follows: This utility model uses a skeleton structure with different inner and outer cross sections to place a folded corrugated filter screen layer.
