Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present utility model.

[0020] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a multi-point defluoridation agent dosing device, including defluoridation water tank 1, support plate 2, middle column 3, movable sleeve 4, locking bolt 5, installation groove 6, positioning bolt 7, positioning nut 8, base plate 9, connecting rod 10, bottom plate 11, inner storage hopper 12, track window 13, mounting hole 14 and outer storage hopper 15, defluoridation water tank 1 top is equipped with support plate 2, support plate 2 top surface center is fixedly installed with middle column 3, and middle column 3 top end is equipped with movable sleeve 4, and movable sleeve 4 top side is equipped with locking bolt 5 by screw thread, and movable sleeve 4 bottom edge is equipped with installation groove 6, and installation groove 6 is equipped with positioning bolt 7, and positioning bolt 7 top is equipped with positioning nut 8, and positioning bolt 7 bottom end is fixedly installed with base plate 9, and base plate 9 bottom surface is rotatably installed with connecting rod 10, and connecting rod 10 bottom end is rotatably connected with bottom plate 11 top surface one end, and bottom plate 11 is arranged on support plate 2 top surface, and bottom plate 11 other end is fixedly installed with inner storage hopper 12, and inner storage hopper 12 bottom end penetrates track window 13, and track window 13 is equipped on support plate 2, and installation hole 14 is equipped on the support plate 2 of track window 13 outside, and support plate 2 upper surface is also provided with outer storage hopper 15, and installation hole 14 and outer storage hopper 15 bottom are pasted.

[0021] The movable sleeve 4 of the example is in sliding connection with the middle column 3, and the front view cross-sectional shape of the movable sleeve 4 is a "N" character type. The above structure design enables the movable sleeve 4 to stably slide along the middle column 3 to adjust the working height, and facilitates the opening of the installation groove 6 and the installation of the positioning bolt 7, the positioning nut 8 and the base plate 9 and other structures.

[0022] The top view shape of the installation groove 6 is a "U" character type, and the installation groove 6 is equally angularly distributed about the center of the movable sleeve 4. The above structure design facilitates the installation or disassembly of a proper number of positioning bolts 7 through the installation groove 6 opening according to the dosing requirements.

[0023] The centers of the base plate 9, the connecting rod 10 and the bottom plate 11 are on the same vertical plane, and the length of the connecting rod 10 is greater than half the length of the middle column 3. The above structure design makes the base plate 9, the connecting rod 10 and the bottom plate 11 have high overall stability, and enables the base plate 9 to stably drive the connecting rod 10 to rotate and drive the bottom plate 11 to move horizontally when moving vertically.

[0024] The diameter of the tubular structure at the bottom of the inner storage hopper 12 is smaller than the width of the track window 13. The track window 13 is distributed at equal angles about the center of the central column 3. The length of the track window 13 is greater than 1.5 times the length of the base plate 11. The above structural design allows the inner storage hopper 12 to be easily installed, disassembled and moved through the track window 13, and its position can be adjusted by a sufficient distance along the track window 13.

[0025] The mounting holes 14 are distributed at equal angles around the center of the central column 3. The mounting holes 14 are engaged with the bottom of the outer storage hopper 15. The above structural design allows the number and position of the outer storage hopper 15 to be easily adjusted.

[0026] Working principle: When using this device, first take out an appropriate number of external storage hoppers 15 according to the fluoride content in the wastewater and insert them into the appropriate mounting holes 14, and install a solenoid valve at the end of the pipe at the bottom of the external storage hopper 15.

[0027] Positioning bolt 7, positioning nut 8, base plate 9, connecting rod 10, base plate 11, and inner storage hopper 12 form a group. Use an appropriate number of groups, such as... Figure 2 As shown, the positioning bolt 7 slides into the mounting groove 6, the positioning nut 8 is rotated to press the bottom of the movable sleeve 4, the base plate 9 is connected and fixed to the movable sleeve 4, and the bottom of the inner storage hopper 12 is inserted into the track window 13. A solenoid valve is installed at the end of the bottom pipe of the inner storage hopper 12. When adjusting the spacing of the inner storage hopper 12, simply push down the movable sleeve 4. The movable sleeve 4 carries the base plate 9 and slides down along the central column 3. The base plate 9 presses down the connecting rod 10, and at the same time pulls the bottom end of the connecting rod 10 outward, while always keeping the bottom plate 11 in contact with the top surface of the support plate 2. The bottom pipe of the inner storage hopper 12 slides outward along the track window 13 until the position of the inner storage hopper 12 is appropriate. Rotate the locking bolts 5, which are distributed at equal angles, to press the central column 3 to fix the position of the movable sleeve 4. The positions of the base plate 9, the connecting rod 10, the bottom plate 11 and the inner storage hopper 12 are also fixed.

[0028] When adding defluorinating agent to the inner storage hopper 12 and the outer storage hopper 15, the defluorinating agent can be discharged into the defluorination water tank 1 simply by controlling the opening of the solenoid valves installed at the bottom pipes of the inner storage hopper 12 and the outer storage hopper 15. The installation and control of the solenoid valves are existing mature technologies, which are well known to those skilled in the art and will not be described in detail here. This is the working principle of the multi-point defluorinating agent dosing device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
