[0016] 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 in 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.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a flow control device for an acid circulation pump, comprising a circulation pump body 1, a connecting pipe 11 is installed at one end of the circulation pump body 1, and a mounting hole 12 is opened on the outer surface of the connecting pipe 11 near the top side, a sealing ring 13 is installed on the outer surface of the connecting pipe 11 near the outside of the mounting hole 12, and a mounting plate 2 is installed on the outer surface of the connecting pipe 11 near the side of the sealing ring 13. The setting of the sealing ring 13 can improve the sealing between the rotating rod 3 and the mounting hole 12, thereby preventing the acid solution inside the connecting pipe 11 from leaking out. The inner diameter of the sealing ring 13 is adapted to the inner diameter of the mounting hole 12, and the top of the rotating rod 3 passes through the inside of the sealing ring 13.

[0018] A screw rod 21 is movably screwed to the outer surface of the mounting plate 2 , and a magnet block 22 is mounted on one end of the screw rod 21 via a bearing. In an initial state, one side surface of the magnet block 22 is adsorbed and fixed to the outer surface of the rotating rod 3 .

[0019] The interior of the mounting hole 12 is rotatably connected with a rotating rod 3, and a hand-held rod 31 is installed at the top of the rotating rod 3. The specific rotation connection method between the mounting hole 12 and the rotating rod 3 is a key connection. The curvature of the magnet block 22 is adapted to the curvature of the outer surface of the rotating rod 3, and the magnet block 22 is arranged at one side of the rotating rod 3. A flow control plate 32 is installed at the bottom end of the rotating rod 3, and stainless steel plates 33 are arranged on both sides of the flow control plate 32. The two groups of stainless steel plates 33 themselves are specially made to be acid-resistant and are not easily corroded when immersed in an acidic solution. The outer diameters of the two groups of stainless steel plates 33 are adapted to the outer diameters of the flow control plates 32, and the outer diameters of the flow control plates 32 and the two groups of stainless steel plates 33 are adapted to the inner diameters of the connecting pipe 11. The hand-held rod 31 and the flow control plate 32 are both arranged horizontally, and the hand-held rod 31 and the rotating rod 3 are arranged in a T shape.

[0020] When in use, one end of the connecting tube 11 will be connected to the external tube body. At this time, the user only needs to rotate the screw rod 21 so that the magnet block 22 can move to one side, so that one side of the magnet block 22 can be separated from the outer surface of the rotating rod 3. After that, the hand-held rod 31 can be rotated accordingly, so that the rotating rod 3 and the flow control plate 32 can be rotated accordingly, so that the flow control plate 32 can be rotated from the horizontal state to the vertical state. According to the above operation, the rotating rod 3 is fixed accordingly by the reverse operation. At this time, the external tube body can be used to flow the acid solution into the interior of the connecting tube 11, and then into the interior of the circulating pump body 1, so that the circulation effect can be achieved under the operation of the circulating pump body 1. When the acid solution in the connecting tube 11 needs to be purged, When controlling the flow of the liquid, the user can separate the magnet block 22 from the rotating rod 3 according to the above operation. After the separation is completed, the hand-held rod 31 can be rotated accordingly, so that the flow control plate 32 can be rotated accordingly at the same time, so that the angle of the flow control plate 32 can be adjusted accordingly inside the connecting pipe 11, and the change in the angle of the flow control plate 32 is set correspondingly to the change in the angle of the hand-held rod 31. When the flow control plate 32 is adjusted at a corresponding angle inside the connecting pipe 11, the flow rate of the acid solution inside the connecting pipe 11 can be controlled, thereby playing a role in controlling the flow. When the angle of the flow control plate 32 is adjusted, the rotating rod 3 can be fixed by the screw 21 and the magnet block 22. The setting of the two sets of stainless steel plates 33 can improve the acid resistance of the flow control plate 32, thereby improving the service life of the flow control plate 32.

[0021] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
