[0026] It should be noted that, without conflict, the embodiments in this embodiment and the features in the embodiments can be combined with each other. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1 - 5 As shown, the purpose of this embodiment is to provide a dyeing liquid circulation filtration device, including a filter body 1. One end of the filter body 1 is provided with a liquid inlet pipe 2, and the other end of the filter body 1 is provided with a liquid outlet pipe 4. The liquid inlet pipe 2 is fixedly installed on one end of the filter body 1. It should be added that: the liquid inlet pipe 2 is fixed to one end of the filter body 1 by welding.

[0028] The liquid outlet pipe 4 is fixedly installed on the other end of the filter body 1. It should be added that: the liquid outlet pipe 4 is fixed to the other end of the filter body 1 by welding.

[0029] Filter assemblies 3 for filtering the waste dyeing liquid are respectively provided on the liquid inlet pipe 2 and the liquid outlet pipe 4. The two filter assemblies 3 are respectively installed at the middle positions of the liquid inlet pipe 2 and the liquid outlet pipe 4. It should be added that: by providing one filter assembly 3 on each of the liquid inlet pipe 2 and the liquid outlet pipe 4, double filtration can be achieved, achieving a better filtration effect. Moreover, the two filter assemblies 3 can also operate at intervals from each other to ensure that when one needs to be replaced or maintained, the other can still work normally to ensure the normal circulation operation of the entire device.

[0030] The filter assembly 3 includes a filter screen fixing plate 31 and a filter screen 35 installed inside the filter screen fixing plate 31. The filter screen 35 is detachably installed in the filter screen fixing plate 31;

[0031] The filter assembly 3 includes a filter screen fixing plate 31, and a filter screen 35 is slidably installed inside the filter screen fixing plate 31.

[0032] It should be added that: two filter screen fixing plates 31 are respectively fixedly installed at the centers of the liquid inlet pipe 2 and the liquid outlet pipe 4. A chute 311 is formed inside the filter screen fixing plate 31. The filter screen 35 is slidably installed in the chute 311. Plugging strips 351 are fixedly installed at the centers of both sides of the filter screen 35. Plugging grooves 312 which are identical in shape and size to the plugging strips 351 and are plugged with each other are formed on both sides of the chute 311. The plugging strips 351 are slidably installed in the plugging grooves 312, and their sizes match each other. Through holes 313 identical to the plugging grooves 312 are penetrated and formed near the centers of both sides of the filter screen fixing plate 31. Bolts 34 for tightly pressing the filter screen 35 are installed in the through holes 313 by means of threading. A pull rod 352 is fixedly installed at the center of the top of the filter screen 35.

[0033] Setting the pull rod 352 at the top of the filter screen 35 can facilitate pulling out the filter screen 35 from the filter screen fixing plate 31. Bolts 34 are arranged on both sides of the filter screen fixing plate 31 so that the filter screen 35 can be fixed. The length of the filter screen 35 is equal to that of the chute 311.

[0034] An installation plate 32 is fixedly installed at the top of the filter screen fixing plate 31. A buckle device is arranged between the installation plate 32 and the filter screen fixing plate 31.

[0035] It should be added that: the buckle device includes a fixing part 331. The fixing part 331 is fixedly installed near the centers of the tops of both sides of the filter screen fixing plate 31. A clamping plate 33 is rotatably installed on the fixing part 331. Clamping seats 332 which are adapted to the clamping plate 33 and are clamped with each other are fixedly installed at the centers of both sides of the installation plate 32. A groove body is formed at the bottom of the installation plate 32. Setting the groove body enables the pull rod 352 to be installed therein without being blocked.

[0036] When the present utility model is specifically used, when the filter screen 35 needs to be cleaned, first, the bolts 34 on both sides of the filter screen fixing plate 31 are rotated by threading and taken out from the through holes 313. Then, the clamping plates 33 near the tops of both sides of the filter screen fixing plate 31 are rotated on the fixing part 331, so as to take out the clamping plates 33 from the clamping seats 332 on both sides of the installation plate 32. Then, the installation plate 32 is taken off from the top of the filter screen fixing plate 31. Place the hand on the pull rod 352 at the top of the filter screen 35, and thus take out the filter screen 35 from the plugging grooves 312 on both sides of the chute 311 through the plugging strips 351 on both sides. After the filter screen 35 is cleaned, then install the filter screen 35 into the chute 311 of the filter screen fixing plate 31. Then, install the bolts 34 into the through holes 313 on both sides of the filter screen fixing plate 31 by threading to tightly press and fix the filter screen 35. Then, install the installation plate 32 on the top of the filter screen fixing plate 31. By rotating the clamping plates 33 on both sides of the filter screen fixing plate 31, the clamping plates 33 are clamped on the clamping seats 332 on both sides of the installation plate 32, so that the installation plate 32 is fixed on the filter screen fixing plate 31.
