[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3A calcium ion recycling device includes a treatment pool 1, a separation box 2, a sludge pump 3 and a water pump 4. The treatment pool 1 stores wastewater containing fluoride ions. Calcium hydroxide will be added to the treatment pool 1 through an external dosing pump to react and generate calcium fluoride to remove fluoride ions. This is the existing technology.

[0021] The bottom of the separation box 2 is sealed and fixedly connected with a partition 5, which divides the separation box 2 into a liquid storage chamber 21 and a decontamination chamber 22. The upper end of the partition 5 is rotatably connected with an annular frame 6. Figure 1 The annular frame 6 is tilted, a filter screen 7 is fixedly connected to the inner wall of the annular frame 6 , a groove 8 is opened above the inner wall of the liquid storage chamber 21 , and the side wall of the annular frame 6 is in contact with the inner wall of the groove 8 .

[0022] The input end of the sludge pump 3 is connected to the lower part of the inner wall of the treatment tank 1 through the sludge inlet pipe 9, and the output end of the sludge pump 3 is fixedly connected to the sludge outlet pipe 10, and the end of the sludge outlet pipe 10 away from the sludge pump 3 is directly opposite to the top of the filter screen 7. The input end of the water pump 4 is connected to the lower part of the inner wall of the liquid storage chamber 21 through the water inlet pipe 11, and the output end of the water pump 4 is connected to the upper part of the inner wall of the treatment tank 1 through the water outlet pipe 12.

[0023] Furthermore, the calcium fluoride generated by the reaction in the treatment tank 1 will flow out to the upper surface of the filter screen 7 through the mud inlet pipe 9, the sludge pump 3 and the mud outlet pipe 10. At this time, the filter screen 7 can filter the wastewater in the calcium fluoride into the liquid storage chamber 21, and the calcium fluoride on the upper surface of the filter screen 7 will fall into the impurity removal chamber 22 to wait for treatment. Then the water pump 4 is started, and the wastewater in the liquid storage chamber 21 will enter the treatment tank 1 again through the water inlet pipe 11 and the water outlet pipe 12, so that the calcium ions in the wastewater can continue to be used, avoiding the prior art that the calcium ions in these wastewaters cannot be used anymore, increasing the amount of calcium hydroxide used, and high processing costs. In addition, calcium hydroxide is frequently added, and the calcium hydroxide addition pump is frequently started and stopped for a long time, and the addition pump and the diaphragm are worn. The diaphragm needs to be replaced frequently, and the life of the addition pump is shortened, which increases the use and maintenance costs.

[0024] It also includes a driving mechanism, which includes an L-shaped plate 13 fixedly connected to the side wall of the separation box 2, a motor 14 fixedly connected to the side wall of the L-shaped plate 13, a cam 15 fixedly connected to the movable end of the motor 14, and the side wall of the cam 15 is in contact with the surface of the annular frame 6.

[0025] When filtering calcium fluoride, the motor 14 rotates to drive the cam 15 to rotate. Since the side wall of the cam 15 is in contact with the surface of the annular frame 6, the annular frame 6 intermittently rotates up and down under the lifting and moving away action of the cam 15, so that the calcium fluoride on the surface of the filter screen 7 is vacated and discharged.

[0026] A cleaning port is provided on the side wall of the separation box 2 facing the cleaning chamber 22. A box cover 16 is rotatably connected to the side wall of the separation box 2 and matched with the cleaning port. The side wall of the box cover 16 is connected to the side wall of the separation box 2 by a plurality of bolts 17, so as to facilitate the cleaning of the calcium fluoride in the cleaning chamber 22.

[0027] When treating wastewater containing fluoride ions, the wastewater containing fluoride ions is stored in the treatment tank 1. At this time, calcium hydroxide is added to the treatment tank 1 through an external dosing pump to react and generate calcium fluoride to remove the fluoride ions.

[0028] Then, the sludge pump 3 is started, and the calcium fluoride generated by the reaction in the treatment tank 1 will flow out to the upper surface of the filter screen 7 through the sludge inlet pipe 9, the sludge pump 3 and the sludge outlet pipe 10. At this time, the filter screen 7 can filter the wastewater in the calcium fluoride into the liquid storage chamber 21, and the calcium fluoride on the upper surface of the filter screen 7 will fall into the impurity removal chamber 22 to wait for treatment. Then, the water pump 4 is started, and the wastewater in the liquid storage chamber 21 will enter the treatment tank 1 again through the water inlet pipe 11 and the water outlet pipe 12, so that the calcium ions in the wastewater can continue to be used;

[0029] During the filtering process, the motor 14 is started, and the rotation of the motor 14 drives the cam 15 to rotate. Since the side wall of the cam 15 is in contact with the surface of the annular frame 6, the annular frame 6 will intermittently rotate up and down under the lifting and moving away action of the cam 15, so that the calcium fluoride on the surface of the filter screen 7 is discharged by evacuation;

[0030] Subsequently, it is only necessary to rotate the plurality of bolts 17 to separate the separation box 2, and then rotate the box cover 16 upward to open the impurity removal port so as to clean the calcium fluoride in the impurity removal chamber 22.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
