Since the middle part of the inner cavity of the hollow tube 61 is filled with a fruit shell carbon filter element 62, and the top and bottom of the fruit shell carbon filter element 62 are filled with fiber medium 63, and the two orifice plates 65 are respectively located on the outside of the two fiber mediums 63, the fruit shell carbon filter element 62 and the fiber medium 63 can be clamped and limited through the two orifice plates 65, and then the liquid flowing through can be filtered through the fruit shell carbon filter element 62 and the fiber medium 63. Filtering treatment, so that it can absorb impurities in the liquid, and then the purpose of liquid purification can be achieved. By disassembling at least one orifice plate 65, it is convenient for the staff to quickly discharge and clean the fruit shell carbon filter element 62 and the fiber medium 63, and then it is convenient for the staff to quickly replace the fruit shell carbon filter element 62 and the fiber medium 63. Since the inner cavities of the two first annular grooves 66 are both provided with sealing rubber rings 67, the sealing rubber rings 67 can be used to strengthen the sealing of the connection between the hollow tube 61 and the top cover 1 and the bottom shell 2, so as to prevent the liquid from leaking during filtration. Through three handles 68, it is convenient for the staff to lift the hollow tube 61, and then move it to a designated position for inspection and treatment.

[0062] Through the support ring 712 in the locking mechanism 7, it can be installed on the outer wall of the bottom shell 2 through the bottom ring 711, and the limiting ring 713 can be installed and fixed. Through the three connecting rods 716, they can be respectively inserted into the three first notches 715 on the outer side wall of the limiting ring 713, and each of them can be installed with a corresponding clamping plate 717 and a rotating tube 718. Since the clamping plate 717 is located in the inner cavity of the second annular groove 714, and a stabilizing ring 733 is installed on the outer side of the limiting ring 713, when the rotating tube 718 rotates, the connecting rod 716 can rotate smoothly in the first notch 715. Since the bottom ends of the three screws 719 are rotatably installed in the inner cavity of the rotating tube 718, and the top ends of the three screws 719 are all connected through the shaft 722 and the transmission rod 7 at the bottom of the clamp 724 The outer gear ring 725 on the outer sides of the three rotating tubes 718 is meshed and connected with the three arc-shaped racks 727 on the rotating ring 726 in a one-to-one manner. Therefore, by unfolding the folding handle 731, it is convenient for the staff to rotate the rotating ring 726 through the folding handle 731, and then the rotating tube 718 can be synchronously driven to rotate smoothly under the meshing of the arc-shaped racks 727 and the outer gear ring 725, so that the screw rod 719, the transmission rod 723 and the clamping head 724 can be pulled downward, so that the clamping head 724 can press the hollow tube 61 with the top cover 1 through the positioning assembly 72, so that the top cover 1, the hollow tube 61 and the bottom shell 2 are tightly installed together. When it is necessary to replace the fruit shell carbon filter element 62 and the fiber medium 63 in the hollow tube 61, this When the screw 719 moves upward, the staff can pull the clamping head 724 out of the positioning assembly 72 to contact the locking position of the two, and under the action of the shaft 722, it is convenient for the staff to fold the connection between the transmission rod 723 and the screw 719. When the above operation is completed, the staff can disassemble the hollow tube 61, which can facilitate the staff to quickly replace the fruit shell carbon filter element 62 and the fiber medium 63. Since a nut 743 is provided on the outer wall of each rotating tube 718 and near the top, when each rotating tube 718 needs to be rotated and adjusted separately The staff can then rotate the rotating ring 726 so that the position between the two adjacent arc-shaped racks 727 is exactly located at the outer gear ring 725. At this time, the outer gear ring 725 is not in contact with the arc-shaped rack 727. The staff can then use a wrench to rotate the rotating tube 718 through the nut 743, thereby being able to move the current screw 719 downward or upward, thereby improving the convenience of using the equipment. By rotating the anti-slip screw 729 in the first internal threaded hole 728, one end of the screw can be inserted into the third annular groove 730 on the outer side wall of the support ring 712, thereby being able to limit the rotating ring 726, so as to prevent the rotating ring 726 from falling off the support ring 712, thereby ensuring the stability of the rotation of the rotating ring 726.Since the outer wall of the rotating ring 726 is bonded with an indicator mark 732 between the two adjacent arc-shaped racks 727, it is convenient for the staff to determine the position of the two adjacent arc-shaped racks 727, and then it is convenient for the staff to locate the position between the two adjacent arc-shaped racks 727 exactly at the outer gear ring 725, and through the positioning screw 736, the second internal thread hole 735 on the stabilizing ring 733 can be penetrated, so that it can be rotatably installed in the first internal thread groove 737 on the support ring 712, so that the stabilizing ring 733 can be stabilized. The fixed ring 733 is stably fixed on the support ring 712, ensuring the stability of the rotation of the rotating tube 718. The screw 741 can penetrate the inner cavity of the internal threaded tube 740 on the shielding ring 738, and its bottom end is rotatably installed in the inner cavity of the second internal thread groove 742 on the limiting ring 713, thereby achieving the purpose of installing the shielding ring 738, so that the shielding ring 738 can shield the upper surface of the rotating ring 726. Through the through hole 739, the rotating tube 718 can conveniently penetrate the shielding ring 738.

[0063] Through the positioning ring 7201 in the positioning assembly 72, it can be fixed to the outer wall of the top cover 1, and the three clamping seats 7202 can be installed. Then, through the three clamping seats 7202, the corresponding three clamping heads 724 can be respectively engaged, and the three clamping heads 724 can be limited, thereby preventing the three clamping heads 724 from rotating, so as to synchronously prevent the screw rod 719 from rotating with the rotating tube 718 when it rotates.
