[0023] See also Figure 1 - Figure 5As shown, a drinking water defluorination treatment tank comprises a treatment tank body 1, a driving motor 20, a filter cage 21 and a stirring rod 22; the bottom end of the stirring rod 22 is rotatably connected to the filter cage 21, and a lifting mechanism is provided on the treatment tank body 1, the lifting mechanism comprises a servo motor 24, the servo motor 24 and a worm 25 are fixed by welding, the worm 25 is meshed with a worm gear 26, the worm gear 26 is rotatably connected to the top of the treatment tank body 1, the worm gear 26 is meshed with a rack 29, a fixing rod 27 is welded and fixed to the bottom end of the rack 29, the fixing rod 27 is welded and fixed to a fixing block 33, the fixing block 33 and the filter cage 21 are fixed together by bolts, a pulley 36 is welded and fixed to the outside of the filter cage 21, four groups of pulleys 36 are provided, the pulley 36 is slidably connected to the inside of a fixing plate 34, and the fixing plate 34 is welded and fixed to the inner wall of the treatment tank body 1;

[0024] During operation, in a drinking water defluorination treatment tank in the above-mentioned technology, if the water level inside the treatment tank is low and cannot completely submerge the filter cage, the filter material filled inside the filter cage cannot fully contact the drinking water, thereby causing the filtering effect of the treatment tank to become low. Through the structural design of the lifting mechanism, the function of lowering the position of the filter cage 21 inside the treatment tank body 1 is realized. When the water entering the treatment tank body 1 cannot completely submerge the filter cage 21, the servo motor 24 can be used to drive the worm 25 to rotate, the worm 25 is meshed with the worm gear 26, and the worm gear 26 rotates, and then the meshing between the worm gear 26 and the rack 29 drives the rack 29 downward. The bottom end of the rack 29 is connected to the fixing block 33 through the fixing rod 27, and the fixing block 33 is fixed to the filter cage 21 through screws. Therefore, the downward movement of the rack 29 will drive the filter cage 21 to move downward inside the treatment tank body 1, so that the water level inside the treatment tank body 1 can submerge the filter cage 21 to achieve a better filtering effect. Four sets of pulleys 36 are fixed on the filter cage 21. When the filter cage 21 moves downward, the pulleys 36 slide in the fixing plate 34 to ensure the stability of the filter cage 21 when moving. The worm gear 26 is rotatably connected to the top of the treatment tank body 1, and the bottom end of the rack 29 passes through the top of the treatment tank body 1 and is connected to the fixing rod 27.

[0025] Furthermore, the servo motor 24 is welded and fixed to the top of the treatment tank body 1, and a protective shell 23 is sleeved on the outer side of the servo motor 24, and a sleeve shell 30 is welded and fixed on the protective shell 23, and the sleeve shell 30 is sleeved on the rack 29;

[0026] During operation, the structural design of the protective shell 23 and the sleeve shell 30 realizes the function of protecting the interior of the protective shell 23 and the rack 29, so as to reduce the influence of external factors on the servo motor 24, the worm 25, the worm wheel 26 and the rack 29, and ensure that they can work normally.

[0027] Furthermore, two sets of fixing strips 31 are welded and fixed on the inner wall of the housing 30, and the fixing strips 31 are slidably connected inside the grooves 32, and the grooves 32 are opened on the front and rear sides of the rack 29;

[0028] During operation, when the rack 29 moves downward, the contact between the fixing bar 31 and the inner wall of the groove 32 allows the rack 29 to remain stable during the movement and not easily shake, thereby ensuring that the rack 29 can properly mesh with the worm gear 26.

[0029] Furthermore, a telescopic rod 40 is welded and fixed to the top of the stirring rod 22, a spring 39 is welded and fixed to the top of the telescopic rod 40, the top of the spring 39 is welded and fixed to the inside of the connecting rod 37, a block 38 is provided on the inner wall of the connecting rod 37, the block 38 slides on the slot 41, the slot 41 is provided on the telescopic rod 40, and the top of the connecting rod 37 is connected to the output shaft of the driving motor 20;

[0030] During operation, the telescopic rod 40 is sleeved inside the connecting rod 37 and a spring 39 is fixed to the top of the telescopic rod 40. When the filter cage 21 moves downward, since the bottom end of the stirring rod 22 is rotatably connected to the filter cage 21, the stirring rod 22 will also move downward, thereby stretching the spring 39 to facilitate the stirring effect of the stirring rod 22 on the filter material inside the filter cage 21. The block 38 is engaged with the slot 41, so that the telescopic rod 40 can move more smoothly when moving downward, and it is also convenient to transmit the rotation of the connecting rod 37 to the telescopic rod 40.

[0031] Furthermore, a gasket 35 is glued and fixed on the bottom end of the inner wall of the fixing plate 34, and the gasket 35 is made of rubber material;

[0032] During operation, the gasket 35 is made of rubber. When the filter cage 21 moves to the maximum position, the pulley 36 fixed on the filter cage 21 will abut against the gasket 35 to avoid direct abutment between the pulley 36 and the inner wall of the fixing plate 34 .

[0033] Furthermore, a stopper 28 is welded and fixed on the top of the fixing rod 27, and the stopper 28 abuts against the inner wall of the treatment tank body 1;

[0034] During operation, the rack 29 is limited by the contact between the stopper 28 and the processing tank body 1 to ensure that the rack 29 does not move upward.

[0035] Working principle: In the prior art, a drinking water defluorination treatment tank, if the water level inside the treatment tank is low and cannot completely submerge the filter cage, the filter material filled in the filter cage cannot fully contact with the drinking water, resulting in a lower filtering effect of the treatment tank. In this case, a drinking water defluorination treatment tank realizes the function of lowering the position of the filter cage 21 inside the treatment tank body 1 through the structural design of the lifting mechanism. When the water entering the treatment tank body 1 cannot completely submerge the filter cage 21, the servo motor 24 can be used to drive the worm 25 to rotate, the worm 25 is meshed with the worm wheel 26, and the worm wheel 26 rotates, and then the meshing between the worm wheel 26 and the rack 29 drives the gear 29 to rotate. The rack 29 moves downward, and the bottom end of the rack 29 is connected to the fixing block 33 through the fixing rod 27, and the fixing block 33 is fixed to the filter cage 21 through screws. Therefore, the downward movement of the rack 29 will drive the filter cage 21 to move downward inside the treatment tank body 1, so that the water level inside the treatment tank body 1 can submerge the filter cage 21 to achieve a better filtering effect. Four sets of pulleys 36 are fixed on the filter cage 21. When the filter cage 21 moves downward, the pulleys 36 slide in the fixing plate 34 to ensure the stability of the filter cage 21 when moving, wherein the worm gear 26 is rotatably connected to the top of the treatment tank body 1, and the bottom end of the rack 29 passes through the top of the treatment tank body 1 and is connected to the fixing rod 27.
