[0023] Embodiment

[0024] As Figure 1 、 Figure 2 and Figure 3 shown, a filtering device for FDY sizing agent proposed in an embodiment of the present utility model includes an outer cylinder 1 and a cylinder cover 5 threadedly connected to the top of the outer cylinder 1. An annular groove 10 is provided at the inner bottom of the outer cylinder 1. An installation frame 3 is arranged at the groove 10 of the outer cylinder 1. The installation frame 3 includes an annular frame body 301 arranged between the groove 10 and the cylinder cover 5, and an end cover 304 threadedly connected to the inner top of the annular frame body 301. An annular bottom plate 306 is integrally formed at the bottom of the annular frame body 301. The bottom plate 306 is adapted to the groove 10 of the outer cylinder 1, and an installation slot one 307 and an installation slot two 308 are respectively provided on the bottom plate 306. A filter element 4 and a filter screen 7 are respectively arranged at the installation slot one 307 and the installation slot two 308 of the bottom plate 306.

[0025] It should be noted that the cylinder cover 5 plays a protective role for the top of the outer cylinder 1. By providing the groove 10 at the inner bottom of the outer cylinder 1, the setting of the groove 10 can realize the firm installation of the installation frame 3 and increase its installation stability. By threadedly connecting the end cover 304 to the top of the annular frame body 301, the end cover 304 can be removed, and then the disassembly and assembly of the inner filter element 4 and the filter screen 7 can be realized. By providing the installation slot one 307 and the installation slot two 308 on the bottom plate 306, the settings of the installation slot one 307 and the installation slot two 308 can respectively realize the firm installation of the filter element 4 and the filter screen 7, play a limiting role, and ensure the installation stability of the filter element 4 and the filter screen 7. During use, the FDY sizing agent is filtered through the filter screen 7 and the filter element 4. Double filtration has a better filtration effect. The filter screen 7 is located inside the filter element 4, which can reduce the filtration pressure of the filter element 4.

[0026] As Figure 1 and Figure 2 shown, in some embodiments, the tops of the filter element 4 and the filter screen 7 are both abutted against the end cover 304, and a sealing ring 303 is provided at the connection between the end cover 304 and the filter element 4.

[0027] It should be noted that the tops of the filter element 4 and the filter net 7 are both in contact with the end cover 304, which can ensure the filtering effect and avoid incomplete filtering at the end. The setting of the sealing ring 303 can ensure the sealing between structures and prevent leakage.

[0028] As Figure 2 shown, in some embodiments, the annular frame body 301 is provided with oil holes 302 distributed in an array.

[0029] It should be noted that the setting of the oil holes 302 can achieve the discharge of the oil agent.

[0030] As Figure 2 shown, in some embodiments, a protrusion 305 is integrally formed at the center of the upper surface of the end cover 304.

[0031] It should be noted that the setting of the protrusion 305 facilitates the rotation operation of the end cover 304.

[0032] As Figure 1 and Figure 3 shown, in some embodiments, an annular protective plate 2 is fixedly connected to one side of the inner part of the outer cylinder 1 within the groove 10, and an oil discharge cavity 11 is provided on the annular protective plate 2.

[0033] It should be noted that by fixedly connecting the annular protective plate 2 inside the outer cylinder 1, with the annular protective plate 2 located outside the groove 10, during the installation process of the annular frame body 301, it can play a role in limiting the annular frame body 301. The annular frame body 301 moves along the annular protective plate 2 and fits into the groove 10, facilitating the assembly of the annular frame body 301 and ensuring the stability of its position.

[0034] As Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, a flange 12 protrudes from the cylinder cover 5, and a sealing cover 6 is threadedly connected to the flange 12. The top of the annular frame body 301 abuts against the sealing cover 6.

[0035] It should be noted that the setting of the flange 12 facilitates the threaded connection of the sealing cover 6. When it is necessary to repair and maintain the filter element 4 and the filter net 7, the sealing cover 6 can be removed and the installation frame 3 can be taken out. The top of the annular frame body 301 abuts against the sealing cover 6, ensuring the stability of the structural cooperation.

[0036] As Figure 1 shown, in some embodiments, an oil inlet 9 is communicated with the center of the bottom of the outer cylinder 1, and an oil outlet 8 is communicated with the upper part of the outer cylinder 1.

[0037] It should be noted that the oil inlet 9 is arranged at the center of the bottom of the outer cylinder 1, so that the FDY sizing agent directly enters the center of the outer cylinder 1, and then passes through the filter screen 7 and the filter element 4 for filtration in sequence, and is discharged through the oil outlet 8 after filtration.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
