[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3, a multi-stage filtering filter bag, comprising a first bag body 1, a first threaded ring 2 is connected to the top of the first bag body 1, and a second threaded ring 3 is installed at the bottom of the first bag body 1, a fixing frame 9 is fixed to the inner side of the second threaded ring 3, and a movable rod 8 is penetrated through the inner side of the fixing frame 9, a linear groove 12 is opened on the upper part of the outer wall of the movable rod 8, and S-shaped grooves 13 are connected to both sides of the linear groove 12, the linear groove 12 is connected to the inner side of the S-shaped groove 13, and the linear groove 12 forms an integrated structure with the movable rod 8 through the slot, by setting the linear groove 12 and the S-shaped groove 13 as a connecting structure, so that the protrusion 11 can smoothly pass through the linear groove 12 and the S-shaped groove 13 and move, the movable rod 8 is connected to the bottom of the fixing frame 9 by a spring, and the top of the movable rod 8 is abutted with a filter screen 7, the aperture of the filter screen 7 is larger than the aperture of the first bag body 1, and by setting the filter screen 7, it can filter large particles of impurities contained in the liquid vertically entering the first bag body 1;

[0022] The outer side of the second threaded ring 3 is connected with the third threaded ring 5, and the second bag body 4 is installed at the bottom of the third threaded ring 5. The structure of the first threaded ring 2 is consistent with that of the third threaded ring 5. By setting the first threaded ring 2 and the third threaded ring 5, it can be connected with the threaded ring with external threads, so that the filter bag can be quickly spliced ​​to achieve the purpose of multi-stage filtration. The bottom end of the second bag body 4 is connected with the fourth threaded ring 6, and the inner side of the fourth threaded ring 6 is installed with a cross. A filter body is installed at the lower inner side of the fourth threaded ring 6. The aperture of the filter body is smaller than the aperture of the filter screen 7, so as to achieve separation with the filter screen 7. The cross and the movable rod 8 are threadedly connected, a reserved hole 10 is provided on the inner side of the fixing frame 9, and a protrusion 11 is connected to the inner wall of the reserved hole 10. The protrusion 11 is slidably connected to the linear groove 12 and the S-shaped groove 13, and the protrusion 11 is fixedly connected to the fixing frame 9. After the movable rod 8 is impacted by the liquid, it moves downward, so the groove body arranged on its outer wall can slide along the outer side of the protrusion 11, so that the movable rod 8 can drive the fourth threaded ring 6 to rotate and drive the second bag body 4 to twist, so as to complete the water squeezing work between the impurities inside the second bag body 4.

[0023] Working principle: When in use, the staff first threadedly connects the first threaded ring 2 to the pipeline, and then fixes the second threaded ring 3. Subsequently, the liquid in the pipeline passes into the first bag body 1. The liquid can press down the filter screen 7 and the movable rod 8, so that the filter screen 7 performs a primary filtering operation on the liquid. After the liquid enters the second bag body 4, the secondary filtering operation is realized through the filter body arranged at the lower inner side of the fourth threaded ring 6. At the same time, after the movable rod 8 is pressed down, it can drive the fourth threaded ring 6 threadedly connected to it to rotate, and the second bag body 4 connected to the fourth threaded ring 6 is twisted, so as to squeeze the impurities filtered in the second bag body 4, squeeze out the moisture between the impurities, and facilitate people to collect the impurities in the filter bag later.
