[0028] For further information, see Figure 1 , Figure 3 and Figure 4 In the present embodiment, the internal thread of the thread groove 8 is connected with a rotating column 10, and the middle part of the rotating column 10 is designed with an arc-shaped structure. The right end of the outer side of the rotating column 10 is rotatably connected with a thread column at a position corresponding to the thread groove 8, and the right end of the rotating column 10 is fixedly connected with a knob 11. By rotating the knob 11, the thread column and the thread groove 8 react, and the thread column moves while the thread groove 8 rotates, squeezing the rotating column 10, and the rotating column 10 moves inside the thread groove 8.

[0029] For further information, see Figure 3 and Figure 4 In this embodiment, a sleeve 12 is fixedly connected to the top of the rectangular box 7, a clip 13 is slidably connected to the inside of the accommodating groove 9, and the clip 13 extends to the inside of the sleeve 12. The bottom of the clip 13 is designed in a semi-arc structure. A receiving frame 14 is fixedly connected to the top of the clip 13, and a first spring 15 is fixedly connected to the inside of the receiving frame 14. When the rotating column 10 moves inside the threaded groove 8, its arc-shaped part will squeeze the clip 13 and realize the contraction of the first spring 15. At the same time, the first spring 15 will be limited by the receiving frame 14 to prevent the first spring 15 from deflecting when contracting, and then the clip 13 will slide upward in the accommodating groove 9.

[0030] For further information, see Figure 3 and Figure 4In this embodiment, a connecting groove is provided inside the clamping strip 13, and a through groove is provided inside the sleeve 12. A hook 16 is rotatably connected inside the through groove. Both ends of the hook 16 extend to the outside of the connecting groove and the through groove respectively. When the clamping strip 13 moves upward, the connecting groove squeezes one end of the hook 16, so that the hook 16 swings inside the through groove, and finally the hook 16 is tilted.

[0031] For further information, see Figure 2 and Figure 5 In this embodiment, the top of the barrier frame 6 is plugged and connected with a cover plate 17, and the interior of the barrier frame 6 is slidably connected with a filter screen 18. There are three groups of filter screens 18, and the density of the three groups of filter screens 18 decreases successively. A square groove is opened at the bottom of the barrier frame 6 corresponding to the position of the sleeve 12, and a square block is symmetrically fixedly connected to the outside of the square groove. During the phosphoric acid extraction process, the density of the extract is usually greater than that of water. Through the three groups of filter screens 18 and the gravity factor, water is retained on the top of the barrier frame 6, and the extract will fall to the bottom of the inner side of the reaction tank 1 to complete the separation work. The barrier frame 6 is set on the sleeve 12, and finally the hook 16 is buckled to press the square block to achieve quick installation of the barrier frame 6.

[0032] For further information, see Figure 2 , Figure 5 and Figure 6 In this embodiment, the top of the cover plate 17 is pluggably connected with a fixing column 19, the top of the fixing column 19 is fixedly connected with a finger ring 20, the bottom end of the fixing column 19 is fixedly connected with a clamping block 21, and the inside of the blocking frame 6 is fixedly connected with a cylinder 22 at a position corresponding to the fixing column 19. A limiting groove 23 is provided at a position corresponding to the clamping block 21 on the inner side wall of the cylinder 22, and an extension cylinder 24 is fixedly connected to the bottom of the cylinder 22. An arc groove 25 is provided on the inner side wall of the extension cylinder 24, and one end of the arc groove 25 is fixedly connected with a U-shaped frame 26, and an extrusion block 27 is symmetrically slidably connected to the inside of the U-shaped frame 26, and the extrusion blocks 27 are far away from each other. One end of the U-shaped frame 26 is fixedly connected with a second spring. When the filter 18 needs to be cleaned, the operator buckles the finger ring 20 and drives the fixing column 19 to rotate, so that the clamping block 21 is disengaged from the pressure on the extrusion block 27, and the second spring is contracted, so that the extrusion block 27 releases the fixation of the clamping block 21, and then the clamping block 21 will be separated from the interior of the U-shaped frame 26, slide out of the interior of the arc groove 25, and enter the interior of the limiting groove 23, and the fixing column 19 is pulled out upward, so that the fixing column 19 is separated from the interior of the cylinder 22, and the cover plate 17 and the barrier frame 6 are separated, and then the filter 18 is taken out.

[0033] In this embodiment, the implementation scenario is specifically as follows: by sleeve-mounting the barrier frame 6 on the outside of the sleeve 12 and rotating the knob 11, the threaded column and the threaded groove 8 react, and the threaded column moves while the threaded groove 8 rotates, and the rotating column 10 is squeezed to move the rotating column 10 inside the threaded groove 8, and its arc-shaped part squeezes the clamping strip 13, and the first spring 15 contracts. At the same time, the first spring 15 is limited by the receiving frame 14 to prevent the first spring 15 from deflecting when contracting, and then the clamping strip 13 slides upward in the accommodating groove 9, and the connecting groove squeezes one end of the hook 16 to swing the hook 16 inside the through groove, and finally the hook 16 buckles the square block to achieve quick installation of the barrier frame 6, and by pouring the phosphoric acid extract into the interior of the reaction tank 1 and inserting the cover 2 into the top of the reaction tank 1, the reaction is achieved. The reaction pool 1 forms a closed space, which effectively prevents external dust from falling into the interior of the reaction pool 1. During the phosphoric acid extraction process, the density of the extract is usually greater than that of water. Through the three groups of filter screens 18 and the gravity factor, the water is retained on the top of the barrier frame 6, and the extract will fall to the bottom of the inner side of the reaction pool 1 to complete the separation work. When the filter screen 18 needs to be cleaned, the operator buckles the finger ring 20 and drives the fixed column 19 to rotate, so that the clamping block 21 is disengaged from the pressure on the extrusion block 27, and the second spring is contracted to release the fixation of the extrusion block 27 to the clamping block 21. Then the clamping block 21 will be separated from the interior of the U-shaped frame 26, slide out of the interior of the arc groove 25, and enter the interior of the limiting groove 23, and pull out the fixed column 19 upward to separate the fixed column 19 from the interior of the cylinder 22, complete the separation of the cover plate 17 and the barrier frame 6, and then take out the filter screen 18.
