[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution:
[0021] In this technical solution, a fluoride-containing wastewater purification and treatment device includes a treatment outer cylinder 1 and a cover 2. The cover 2 is installed at the upper end of the treatment outer cylinder 1. A motor 3 is installed at the center of the upper surface of the cover 2. The motor 3 is electrically connected to an external power source. An agitator blade 4 is installed through the lower wall of the cover 2 at the output end of the motor 3.
[0022] The upper wall of the cover 2 is equipped with a main electric control push rod 5, which is electrically connected to an external power source. The output end of the main electric control push rod 5 passes through the lower wall of the cover 2. The inner side of the outer processing cylinder 1 is equipped with a screen cylinder 6, and the upper end of the outer wall of the screen cylinder 6 is equipped with a connecting mechanism 7. The output end of the main electric control push rod 5 is installed on the upper wall of the connecting mechanism 7.
[0023] In this technical solution, the motor 3 provides power to the stirring blade 4, causing it to rotate inside the screen cylinder 6, thereby achieving stirring and mixing of the internal substances and ensuring a full reaction. After stirring and mixing is completed, the main electric control push rod 5 can be controlled to move the screen cylinder 6 upward a short distance. Then, the submersible motor 13 can be started to drive the screen cylinder 6 to rotate rapidly, thereby throwing the wastewater inside the screen cylinder 6 into the outer treatment cylinder 1. The sediment will be trapped inside the screen cylinder 6, achieving a rapid separation effect and saving the time waiting for sedimentation.
[0024] In some technical solutions, a wastewater inlet pipe 8 and a calcium salt dispensing pipe 9 are inserted and installed at the upper end of the cover 2. Both the wastewater inlet pipe 8 and the calcium salt dispensing pipe 9 are connected to the screen cylinder 6. External wastewater enters the screen cylinder 6 through the wastewater inlet pipe 8, and external calcium salt enters the screen cylinder 6 through the calcium salt dispensing pipe 9.
[0025] In this technical solution, the wastewater inlet pipe 8 is specifically used to transport fluoride-containing wastewater to the screen cylinder 6, while the calcium salt dosing pipe 9 is responsible for accurately delivering calcium salt and other precipitants into the screen cylinder 6. By adding calcium salt, fluoride ions and cations in the reagent form insoluble fluoride precipitates, thereby achieving the purpose of defluorination.
[0026] In some technical solutions, the connecting mechanism 7 includes a fixed ring 71, an annular groove 72, a sliding block 73, a positioning hole 74, and a positioning pin 75. The fixed ring 71 is welded to the outside of the screen cylinder 6. The outer wall of the fixed ring 71 is provided with an annular groove 72. There are two sliding blocks 73. Both sliding blocks 73 are slidably installed in the annular groove 72. The side walls of the two sliding blocks 73 and the side wall of the main electric control push rod 5 are provided with positioning holes 74. The positioning pin 75 is inserted and installed in the positioning hole 74.
[0027] In this technical solution, the fixing ring 71 is fixedly connected to the screen cylinder 6, the annular groove 72 provides a sliding track for the sliding block 73, and the two sliding blocks 73 are connected to the main electric control push rod 5 through the positioning hole 74 and the positioning pin 75. This not only realizes the driving effect of the main electric control push rod 5 on the screen cylinder 6, but also allows the screen cylinder 6 to be quickly separated by pulling out the positioning pin 75, making it convenient to remove the screen cylinder 6 after the wastewater treatment is completed and clean the sediment inside.
[0028] In some technical solutions, an auxiliary electric control push rod 10 is installed on the side wall of the outer cylinder 1, and the output end of the auxiliary electric control push rod 10 is installed on the lower wall of the cover 2.
[0029] In this technical solution, the auxiliary electric control push rod 10 can drive the cover 2 to move up and down. When it is necessary to open the outer processing cylinder 1, the auxiliary electric control push rod 10 extends and drives the cover 2 to rise, exposing the internal space of the outer processing cylinder 1, which facilitates the disassembly and cleaning of the internal screen cylinder 6.
[0030] In some technical solutions, a water pump 11 is installed on the side wall at the lower end of the outer cylinder 1. The water pump 11 is electrically connected to an external power source. The input end of the water pump 11 is connected to the inner cavity of the outer cylinder 1. A drain pipe 12 is installed at the output end of the water pump 11.
[0031] In this technical solution, the water pump 11 provides power for the discharge of purified wastewater from the outer cylinder 1. It draws clean water from the outer cylinder 1 through the input end and then transports it to a designated location through the drain pipe 12, thereby realizing the automatic discharge of purified wastewater, avoiding manual scooping, and improving the automation level and working efficiency of the device.
[0032] In some technical solutions, a submersible motor 13 is installed on the inner side wall of the outer cylinder 1. The submersible motor 13 is electrically connected to an external power source. A gear 14 is installed at the output end of the submersible motor 13. A toothed ring 15 is installed on the outer side wall of the fixing ring 71. The gear 14 and the toothed ring 15 are meshed together.
[0033] In this technical solution, when the submersible motor 13 is working, it drives the gear 14 to rotate. Since the gear 14 meshes with the gear ring 15, it drives the fixed ring 71 and the screen cylinder 6 to rotate. On the one hand, during mixing, the screen cylinder 6 rotates itself while being stirred by the stirring blade 4, which further enhances the mixing effect of the substances in the screen cylinder 6 and increases the reaction rate. On the other hand, during fixed separation, the screen cylinder 6 can be rotated quickly to form a structure similar to a spin dryer, which can quickly separate the solid and liquid.
[0034] Working principle: When using this fluoride-containing wastewater purification device, firstly, fluoride-containing wastewater is introduced into the screen cylinder 6 through the wastewater inlet pipe 8. At the same time, calcium salt is added into the screen cylinder 6 through the calcium salt addition pipe 9. The motor 3 is started, which drives the stirring blade 4 to rotate, stirring the wastewater and calcium salt in the screen cylinder 6, so that fluoride ions react fully with calcium salt to generate calcium fluoride precipitate. The submersible motor 13 is started, and the screen cylinder 6 is rotated through the meshing transmission of gear 14 and gear ring 15 to enhance the mixing effect. During the reaction, the purified wastewater enters the outer treatment cylinder 1 through the screen holes of the screen cylinder 6, while the calcium fluoride precipitate is trapped in the screen cylinder 6. At the same time, the water pump 11 is started to discharge the purified and defluorinated wastewater through the drain pipe 12.
[0035] When it is necessary to clean the screen cylinder 6, start the auxiliary electric control push rod 10 to make it lift the cover 2, so that the screen cylinder 6 is exposed outside the processing outer cylinder 1; then pull out the positioning pin 75, remove the screen cylinder 6 from the main electric control push rod 5 for cleaning, and reinstall it after cleaning.
