Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically a high-concentration fluoride ion wastewater treatment device. Background Technology

[0002] High-concentration fluoride ion wastewater refers to industrial or domestic wastewater containing a high concentration of fluoride ions. Fluoride ions (F...) ⁻ Fluoride ions are highly toxic to the environment and human health at certain concentrations. Therefore, there are strict requirements for the treatment and discharge of high-concentration fluoride ion wastewater. Direct discharge of high-concentration fluoride ion wastewater will cause harm to the environment and human health. Therefore, high-concentration fluoride ion wastewater needs to be treated before discharge.

[0003] In conventional high-concentration fluoride ion wastewater treatment processes, neutralization liquid is mixed with the high-concentration fluoride ion wastewater to drive flocculation, sedimentation, and filtration. Therefore, the treatment of high-concentration fluoride ion wastewater requires transfer devices such as water pumps to transport the wastewater, which increases the energy consumption and processing space required, resulting in resource waste. To address this, we propose a high-concentration fluoride ion wastewater treatment device. Utility Model Content

[0004] To address the shortcomings of existing high-concentration fluoride ion wastewater treatment devices, this invention provides a high-concentration fluoride ion wastewater treatment device. It features a flocculation tank and a sedimentation tank stacked together. After flocculation in the flocculation tank, the flocculated material can be automatically transferred into the sedimentation tank. Meanwhile, the outer shell of the filter box is located on one side of the flocculation tank, reducing the space required for equipment use and the energy consumption during liquid transfer, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high-concentration fluoride ion wastewater treatment device, including a flocculation box, a sedimentation box installed at the lower end of the flocculation box, a filter box shell installed on the side of the sedimentation box, a filter cartridge movably sleeved inside the filter box shell, a top cover installed at the upper end of the flocculation box, a rotating seat movably sleeved in the middle of the top cover, a neutralizing liquid dispensing box movably sleeved at the upper end of the rotating seat, a first rotating shaft and a second rotating shaft respectively installed on both sides inside the flocculation box, fixed rollers fixedly connected to the outside of the first rotating shaft and the second rotating shaft, a movable roller movably installed outside the first rotating shaft and the second rotating shaft and between the two sets of fixed rollers, a first rack chain sleeved on the outside of the movable roller and the fixed roller, and a baffle fixedly connected to the outside of the first rack chain.

[0006] Preferably, the sedimentation tank is located at the lower end of the flocculation tank, a solid impurity discharge port is provided on one side of the lower part of the sedimentation tank, and a liquid discharge pipe is installed on the upper part of the other side of the sedimentation tank, the liquid discharge pipe extending into the interior of the filter cartridge.

[0007] Preferably, the flocculation box has a discharge port at its lower end, and a baffle is installed between the flocculation box and the sedimentation box at the lower end of the discharge port. The internal threads of the baffle are fitted with lead screws.

[0008] Preferably, a filter screen is installed inside the filter cartridge, and a drain port is installed at the lower end of the filter box shell.

[0009] Preferably, the neutralizing liquid dispensing tank is fixed to the outside of the upper cover by a bracket, and a motor is installed on the upper part of the upper cover. A gear installed at one end of the motor meshes with the outside of the rotating seat.

[0010] Preferably, the rotating seat has a neutralizing liquid delivery port inside, and eight sets of discharge pipes are fixedly connected at equal intervals to the lower end of the neutralizing liquid delivery box. The neutralizing liquid delivery port is located at the lower end of the discharge pipe, and the lower end of the discharge pipe is fitted and installed on the upper part of the rotating seat.

[0011] Preferably, a first gear is fixedly connected to the ends of the first rotating shaft and the second rotating shaft. A gear set is installed on the outside of the flocculation box and aligned with the first gear. The gear set includes two sets of gears. A second rack chain is installed on the outside of the first set of gears and the first gear. The second gears installed on the outside of the two sets of gears mesh with each other. The movable roller and the fixed roller installed on the outside of the first rotating shaft and the second rotating shaft are arranged in a crisscross pattern.

[0012] Compared with existing high-concentration fluoride ion wastewater treatment devices, this utility model has the following advantages: 1. This high-concentration fluoride ion wastewater treatment device uses a neutralization liquid dispensing tank to drive the neutralization liquid downward from the inside of the rotating seat. At the same time, the motor installed on the outside of the gear set is started to control the first rotating shaft and the second rotating shaft to rotate in opposite directions. The opposite rotation of the first rotating shaft and the second rotating shaft does not interfere with the first rack chain. That is, the adjacent first rack chains rotate in opposite directions. At the same time, the first rack chain drives the baffle to rotate. The baffle drives the high-concentration fluoride ion wastewater to mix and stir, thereby improving the mixing efficiency between the high-concentration fluoride ion wastewater and the neutralization liquid.

[0013] 2. This high-concentration fluoride ion wastewater treatment device uses a flocculation box to drive the high-concentration fluoride ion wastewater to undergo flocculation treatment. The flocculated liquid is then transported to the interior of a sedimentation tank for sedimentation. The sedimented liquid can then be transported to the interior of a filter cartridge. The rotation of the filter cartridge drives the high-concentration fluoride ion wastewater to be filtered again. In other words, the wastewater treatment device is assembled into a whole, which improves the efficiency of high-concentration fluoride ion wastewater treatment. Attached Figure Description

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.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A high-concentration fluoride ion wastewater treatment device includes a flocculation tank 1, a sedimentation tank 2 installed at the lower end of the flocculation tank 1, a filter housing 7 installed on the side of the sedimentation tank 2, and a filter cartridge 8 movably connected inside the filter housing 7. The filter housing 7 and the filter cartridge 8 drive the high-concentration fluoride ion wastewater to filter, further improving the wastewater treatment efficiency. A top cover 9 is installed at the upper end of the flocculation tank 1, and a rotating seat 10 is movably connected to the middle of the top cover 9. A neutralization liquid dispensing tank 12 is movably connected to the upper end of the rotating seat 10. The neutralization liquid dispensing tank 12 drives the reactants to be discharged downward through the rotating seat 10, ensuring the efficiency of impurity discharge. The flocculation tank 1 has two sides inside the sides respectively... The system is equipped with a first rotating shaft 15 and a second rotating shaft 16. Fixed rollers 23 are fixedly connected to the outside of the first rotating shaft 15 and the second rotating shaft 16. Movable rollers 17 are movably installed outside the first rotating shaft 15 and the second rotating shaft 16 and between the two sets of fixed rollers 23. A first rack chain 18 is sleeved on the outside of the movable roller 17 and the fixed rollers 23. A baffle 19 is fixedly connected to the outside of the first rack chain 18. The first rotating shaft 15 and the second rotating shaft 16 rotate in opposite directions, that is, the five sets of first rack chains 18 are arranged in a crisscross pattern. The baffle 19 is used to push the liquid to stir, thereby improving the flocculation efficiency of high-concentration fluoride ion wastewater inside the flocculation box 1.

[0018] Please see Figure 2 The sedimentation tank 2 is located at the lower end of the flocculation tank 1. A solid impurity discharge port 5 is provided on one side of the lower part of the sedimentation tank 2, and a liquid discharge pipe 6 is installed on the upper part of the other side of the sedimentation tank 2. The liquid discharge pipe 6 extends into the interior of the filter cartridge 8. By installing the solid impurity discharge port 5 and the liquid discharge pipe 6 at the lower end and upper part of the side of the sedimentation tank 2, the sedimentation tank 2 drives the pre-treated wastewater to settle. After settling, the impurities accumulate at the lower end of the sedimentation tank 2. At the same time, when cleaning the impurities, the valve installed inside the solid impurity discharge port 5 can be opened to drive the solid impurities out. Meanwhile, the filtered wastewater accumulates at the upper end of the interior of the sedimentation tank 2. When the wastewater overflows the liquid discharge pipe 6, the liquid discharge pipe 6 drives the overflowing wastewater to the interior of the filter cartridge 8, where the wastewater is filtered again by the filter cartridge 8.

[0019] Please see Figure 2 The flocculation tank 1 has a discharge port at its lower end, and a baffle 3 is installed at the lower end of the discharge port between the flocculation tank 1 and the sedimentation tank 2. The internal threads of the baffle 3 are installed with screws 4. The wastewater and the neutralizing agent are fully mixed inside the discharge port between the flocculation tank 1 and the sedimentation tank 2 through the baffle 3. After the wastewater and the neutralizing agent are fully mixed inside the flocculation tank 1, flocculent matter is formed. At the same time, the screw 4 is activated, and the screw 4 drives the baffle 3 to move, that is, the opening at the lower end of the flocculation tank 1 is opened. At the same time, the pre-treated wastewater is transported to the interior of the sedimentation tank 2, where the wastewater settles, thereby improving the wastewater treatment efficiency.

[0020] Please see Figure 2The filter cartridge 8 is equipped with a filter screen inside, and the lower end of the filter housing 7 is equipped with a drain port. The filter cartridge 8 is installed inside the filter housing 7, and the filter housing 7 is installed at an angle. After the sewage is discharged through the liquid discharge pipe 6, the discharged sewage flows into the interior of the filter cartridge 8. At the same time, the filter cartridge 8 is controlled to rotate, and the filter cartridge 8 drives the sewage to filter. The impurities filtered again are discharged through the outlet at the end of the filter housing 7. At the same time, the lower end of the filter housing 7 is equipped with a drain port, that is, the filtered liquid is discharged through the drain port, thereby improving the sewage treatment efficiency.

[0021] Please see Figure 5 The neutralizing liquid dispensing tank 12 is fixed to the outside of the upper cover 9 by a bracket. A motor 14 is installed on the upper part of the upper cover 9. A gear installed at one end of the motor 14 meshes with the outside of the rotating seat 10. By starting the motor 14, the motor 14 drives the gear to mesh with the rotating seat 10. At the same time, the neutralizing liquid dispensing tank 12 is installed on the upper part of the upper cover 9 by the bracket to ensure that the neutralizing liquid dispensing tank 12 maintains a stable state.

[0022] Please see Figure 5 The rotating seat 10 has a neutralizing liquid delivery port 11 inside. Eight sets of discharge pipes 13 are fixedly connected at equal intervals to the lower end of the neutralizing liquid dispensing tank 12. The neutralizing liquid delivery port 11 is located at the lower end of the discharge pipe 13, and the lower end of the discharge pipe 13 is attached to the upper part of the rotating seat 10. Neutralizing liquids such as alum are filled into the neutralizing liquid dispensing tank 12. At the same time, the rotating seat 10 maintains a uniform rotation state. That is, the neutralizing liquid delivery port 11 is sequentially connected to the discharge pipes 13 at the lower end of the neutralizing liquid dispensing tank 12. The discharge pipes 13 drive the neutralizing liquid to be discharged downward through the neutralizing liquid delivery port 11, thereby improving the uniformity of the downward discharge of the neutralizing liquid.

[0023] Please see Figure 3 and Figure 4A first gear 20 is fixedly connected to the ends of the first rotating shaft 15 and the second rotating shaft 16. A gear set 21 is installed on the outside of the flocculation box 1, aligned with the first gear 20. The gear set 21 includes two sets of gears. A second rack chain 22 is installed on the outside of the first set of gears and the first gear 20. The second gears installed on the outside of the two gear sets 21 mesh with each other. The movable roller 17 and the fixed roller 23 installed on the outside of the first rotating shaft 15 and the second rotating shaft 16 are arranged in a crisscross pattern. The gear set 21 is driven to rotate by a motor. After the two gear sets 21 mesh with each other, they rotate in opposite directions. At the same time, the second rack chain... Under the action of chain 22, the first rotating shaft 15 and the second rotating shaft 16 rotate in opposite directions. The fixed roller 23 and the movable roller 17 are staggered. That is, when the movable roller 17 drives the first rack chain 18 to rotate, it does not interfere with the second rotating shaft 16. At the same time, the second rotating shaft 16 can drive the adjacent first rack chain 18 to rotate in the opposite direction. That is, among the five sets of first rack chains 18, three sets of first rack chains 18 keep rotating clockwise and two sets of first rack chains 18 rotate counterclockwise. At the same time, during the rotation of the baffle 19, the fullness of the mixing of liquids inside the flocculation box 1 is improved, and the efficiency of liquid sewage flocculation is enhanced.

[0024] Working principle: During use, high-concentration fluoride ion wastewater is transported into the flocculation tank 1. Simultaneously, the motor installed on the outside of the gear set 21 is started, with the first rotating shaft 15 and the second rotating shaft 16 rotating in a crisscross pattern, and the five sets of first rack chains 18 rotating in a crisscross pattern. This drives the high-concentration fluoride ion wastewater to be stirred, improving the thoroughness of the stirring. The neutralization liquid addition tank 12 is filled with neutralizing agents such as alum, ensuring that the harmful substances in the high-concentration fluoride ion wastewater mix with the alum and form flocculent matter. After the high-concentration fluoride ion wastewater is stirred, the lead screw 4 is started, controlling the baffle 3 to shift. The high-concentration fluoride ion wastewater automatically slides into the sedimentation tank 2, where it settles. The liquid that overflows the liquid discharge pipe 6 slides into the filter cartridge 8. When the filter cartridge 8 rotates, it drives the high-concentration fluoride ion wastewater to be filtered. The filtered liquid is discharged through the lower end of the filter box shell 7, further improving the filtration efficiency of the high-concentration fluoride ion wastewater.
