[0002] To overcome the problem of nylon 66 salt solution deterioration during production, activated carbon is generally added for decolorization and then circulated for filtration.
[0003] Chinese patent with announcement number CN204447500U discloses a columnar filter device for purifying nylon 66 salt. In use, nylon 66 salt solution is introduced from the material inlet and reaches each columnar filter for filtration. The salt solution permeates through the micropores of the plastic filter cylinder, and the filtered water is discharged from the material outlet.
[0004] However, the aforementioned columnar filter device for nylon 66 salt purification has multiple columnar filters fixed on the side of the material outlet. When the columnar filters need to be replaced after a period of use, it is necessary to release the positioning of the columnar filters one by one and then disassemble the columnar filters, which makes the replacement efficiency relatively slow.
[0005] In view of this, this utility model is proposed. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a filtration device for nylon 66 salt purification.

Multiple extrusion blocks are arranged in an array along the height direction on the inner side of the L-shaped connecting strips. The extrusion blocks are elastically slidably fitted on the inner side of the L-shaped connecting strips. An installation hole is provided on the side of the outlet pipe. A columnar filter with one end inserted into the installation hole is provided on one side of the extrusion block.
[0009] Optionally, the bottom of the frame is provided with mounting holes corresponding to the water inlet pipe and the water outlet pipe, and the water inlet pipe and the water outlet pipe are fixed in the mounting holes.
[0010] Optionally, an exhaust valve is connected to the upper side of the filter barrel, and the inner wall of the side of the L-shaped connecting strip is provided with a groove corresponding to the extrusion block. A spring is provided between the inner wall of the groove and the extrusion block, and one end of the extrusion block is slidably fitted in the groove.
[0011] Optionally, the fixing plate is a shell structure, and one side of the fixing plate is provided with a mounting groove corresponding to the L-shaped connecting strip, with one end of the L-shaped connecting strip located in the mounting groove.
[0012] Optionally, a threaded rod that rotatably engages with an L-shaped connecting strip is provided inside the fixed disk, and a rotating shaft that meshes with the threaded rod is provided on the fixed disk, with a handwheel at the upper end of the rotating shaft.
[0013] Optionally, a first bevel gear is provided at the bottom of the rotating shaft, and a second bevel gear is provided at one end of the threaded rod, with the first bevel gear meshing with the second bevel gear.

Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] Please see Figs. 1-3 As shown, this embodiment provides a filtration device for purifying nylon 66 salt, including a frame 1 and a filter barrel 2 disposed on the upper side of the frame 1. The frame 1 is connected to an inlet pipe 3 and an outlet pipe 4. One end of the outlet pipe 4 extends into the filter barrel 2 and is provided with a fixing plate 5. Multiple L-shaped connecting strips 6 are arranged in a circular array on the side of the fixing plate 5. Multiple extrusion blocks 7 are arranged in a vertical array on the inner side of the L-shaped connecting strips 6. The extrusion blocks 7 are elastically slidably fitted on the inner side of the L-shaped connecting strips 6. The side of the outlet pipe 4 is provided with a mounting hole 8. A columnar filter 9 is provided on one side of the extrusion block 7, with one end inserted into the mounting hole 8.
[0028] The columnar filter 9 includes a plastic filter cylinder, one end of which is provided with an annular protrusion, and the inner wall of the plastic filter cylinder is provided with an activated carbon layer.
[0029] Nylon 66 brine enters the filter tank 2 through the inlet pipe 3, passes through multiple column filters 9, and is discharged through the outlet pipe 4. When replacing the column filters 9, the filter tank 2 is removed, and then the column filters 9 are manually pushed to make the squeezing block 7 slide elastically, so that one end of the column filters 9 slides out of the mounting hole 8, which facilitates quick disassembly of the column filters 9. The squeezing block 7 is then manually pushed through the column filters 9 to slide elastically, and then one end of the column filters 9 is inserted into the mounting hole 8. The squeezing block 7 elastically positions the column filters 9, which improves the positioning efficiency of the column filters 9 and the replacement efficiency of the column filters 9.
[0030] Please see Fig. 2 As shown, the bottom of the frame 1 in this embodiment is provided with mounting holes corresponding to the water inlet pipe 3 and the water outlet pipe 4. The water inlet pipe 3 and the water outlet pipe 4 are fixed in the mounting holes to facilitate the installation of the water inlet pipe 3 and the water outlet pipe 4. An exhaust valve 10 is connected to the upper side of the filter barrel 2. The inner wall of the side of the L-shaped connecting strip 6 is provided with a groove 601 corresponding to the extrusion block 7. A spring 602 is provided between the inner wall of the groove 601 and the extrusion block 7. One end of the extrusion block 7 is slidably fitted in the groove 601 to facilitate the elastic sliding of the extrusion block 7 by the spring 602.
[0031] Please see Figs. 2-3 As shown, the fixing plate 5 in this embodiment is a shell structure. One side of the fixing plate 5 is provided with a mounting groove 11 corresponding to the L-shaped connecting strip 6. One end of the L-shaped connecting strip 6 is located in the mounting groove 11. A threaded rod 12 connected to the L-shaped connecting strip 6 is rotatably fitted inside the fixing plate 5. A rotating shaft 13 meshing with the threaded rod 12 is rotatably fitted on the fixing plate 5. A handwheel is provided at the upper end of the rotating shaft 13, and a first bevel gear 14 is provided at the bottom end of the rotating shaft 13. A second bevel gear 15 is provided at one end of the threaded rod 12. The first bevel gear 14 and the second bevel gear 15 mesh, so that when the spring 602 experiences elastic fatigue after long-term use, the rotating shaft 13 is rotated by the handwheel to drive the first bevel gear 14 and the second bevel gear 15. The rotation of the threaded rod 12 causes the L-shaped connecting strip 6 to slide, increasing the compression of the spring 602 and compensating for the elasticity of the spring 602.
[0032] Please see Figs. 2-3 As shown, in this embodiment, a first bearing corresponding to the threaded rod 12 is embedded in the inner wall of the fixed disk 5. A smooth surface is provided on the outer side of one end of the threaded rod 12. One end of the threaded rod 12 is fixed in the first bearing, which facilitates the improvement of the rotation stability of the threaded rod 12 through the first bearing. A second bearing corresponding to the rotating shaft 13 is embedded in the top surface of the inner wall of the fixed disk 5. The rotating shaft 13 is fixed in the second bearing, which facilitates the improvement of the rotation stability of the rotating shaft 13 through the second bearing.
[0033] Working principle: Nylon 66 brine enters the filter tank 2 through the inlet pipe 3, passes through multiple columnar filters 9, and is discharged through the outlet pipe 4. When replacing the columnar filters 9, the filter tank 2 is removed, and then the columnar filters 9 are manually pushed to push the squeezing block 7 to slide and compress the spring 602, so that one end of the columnar filters 9 slides out of the mounting hole 8, which facilitates quick disassembly of the columnar filters 9. The squeezing block 7 is manually pushed through the columnar filters 9 to slide and compress the spring 602, and then one end of the columnar filters 9 is inserted into the mounting hole 8. The squeezing block 7 is elastically positioned by the spring 602, which facilitates the positioning efficiency of the columnar filters 9 and improves the replacement efficiency of the columnar filters 9. When the spring 602 becomes fatigued after long-term use, the rotating shaft 13 is rotated by the handwheel to drive the first bevel gear 14 and the second bevel gear 15. The threaded rod 12 rotates and drives the L-shaped connecting strip 6 to slide, increasing the compression of the spring 602 and compensating for the elasticity of the spring 602.
