Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] This utility model discloses a fluoride ion adsorption device for wastewater treatment, as described below. Figures 1 to 3 Please provide a detailed explanation.

[0024] A fluoride ion adsorption device for wastewater treatment includes a wastewater tank 1. An inlet 11 and an outlet 12 are respectively provided on a set of symmetrical side walls of the wastewater tank 1. A fluoride ion absorption plate 2 is installed inside the wastewater tank 1, perpendicular to the flow direction of the water in the wastewater tank 1, and the fluoride ion absorption plate 2 is slidably abutting against the inner wall of the wastewater tank 1. The top wall of the wastewater tank 1 is open. A lifting assembly 3 for controlling the up-and-down movement of the fluoride ion absorption plate 2 is provided above the wastewater tank 1. The fluoride ion absorption plate 2 and the lifting assembly 3 are detachably connected via a quick-change assembly 4.

[0025] This invention utilizes a wastewater tank 1 with a replaceable fluoride ion absorption plate 2 to absorb fluoride ions from chemical wastewater, thus preventing the direct discharge of chemical wastewater containing large amounts of fluoride ions and avoiding environmental pollution. The lifting assembly 3 and quick-replacement assembly 4 enable rapid removal and replacement of the fluoride ion absorption plate 2. When the collection efficiency of the fluoride ion absorption plate 2 decreases to a certain value, it can be removed from the wastewater tank 1 using the lifting assembly 3 and replaced using the quick-replacement assembly 4.

[0026] In some embodiments, the fluoride ion absorption plate 2 includes a fixing frame 21, and a fluoride ion absorption layer 22 is filled within the space enclosed by the frame 21. The fluoride ion absorption layer 22 is configured as an activated carbon fiber layer. When wastewater passes through the space in the middle of the frame, it passes through the fluoride ion absorption layer 22, thereby achieving the absorption effect of fluoride ions.

[0027] In some embodiments, the lifting assembly 3 includes a gantry frame 31 spanning above the wastewater tank 1. A lifting cover 32 is provided on the side of the gantry frame 31 facing the wastewater tank 1, and a lifting screw 33 is provided on the side of the lifting cover 32 facing away from the wastewater tank 1. The lifting screw 33 passes through the gantry frame 31 and is threadedly connected to the gantry frame 31. The side of the lifting cover 32 facing the wastewater tank 1 is detachably connected to the fluoride ion absorption plate 2 via a quick-change assembly 4. The lifting cover 32 can move in a direction perpendicular to the wastewater tank 1 under the action of the lifting screw 33, thereby lifting the fluoride ion absorption plate 2. Furthermore, in the normal operating state of the fluoride ion absorption plate 2, the lifting cover 32 can completely fit against the top end face of the wastewater tank 1, thus completely covering the opening on the top end face of the wastewater tank 1. This prevents external debris from entering the wastewater tank 1 or chemical wastewater from overflowing or splashing out of the wastewater tank 1 into the external environment.

[0028] In some embodiments, a sliding groove 34 is provided on the inner sidewall of the gantry frame 31, and a slider 35 is provided on the lifting cover 32 in conjunction with the sliding groove 34. The sliding groove 34 and the slider 35 can limit the movement of the lifting cover 32, thereby preventing the lifting cover 32 from deviating at an angle during the lifting and moving process, and thus ensuring that the fluoride ion absorption plate 2, which is detachably connected to the lifting cover 32, can be inserted into the wastewater tank 1 in a direction perpendicular to the flow direction of the wastewater in the wastewater tank 1.

[0029] In some embodiments, the quick-change component 4 includes a snap-fit ​​groove 41 vertically disposed on the bottom wall of the lifting cover 32. Multiple fixing pins 42 are disposed through the side wall of the snap-fit ​​groove 41, and a pin hole 43 is provided on the fluoride ion absorption plate 2 corresponding to each fixing pin 42. After the fluoride ion absorption plate 2 is inserted into the snap-fit ​​groove 41, the operator can complete the fixed connection of the fluoride ion absorption plate 2 by inserting the fixing pins 42 into the pin holes 43. When the fluoride ion absorption plate 2 needs to be replaced, the operator can disassemble the fluoride ion absorption plate 2 by removing the fixing pins 42.

[0030] In some embodiments, the end of the fixing pin 42 facing away from the fluoride ion absorption plate 2 is provided with a fixing ring 44, and a spring 45 is fixedly connected between the fixing ring 44 and the outer wall of the snap-fit ​​groove 41. The spring 45 is sleeved on the outside of the fixing pin 42. The arrangement of the fixing ring 44 and the spring 45 ensures that the fixing pin 42 will never detach from the snap-fit ​​groove 41, avoiding the situation where the fixing pin 42 is easily lost after detaching from the snap-fit ​​groove 41.

[0031] In one embodiment, the normal length of the spring 45 should not be greater than the distance between the fixing ring 44 and the outer wall of the snap-fit ​​groove 41 when the fixing pin 42 is fully inserted into the pin hole 43, so as to ensure that the fixing pin 42 can always be subjected to the force of insertion into the pin hole 43 when subjected to external forces such as vibration and water flow impact, thus ensuring the connection stability between the fixing pin 42 and the pin hole 43.

[0032] In some embodiments, a handwheel 36 is provided at one end of the lifting screw 33 that passes through the portal frame 31. The handwheel 36 facilitates the operator's control of the lifting screw 33. In one embodiment, a drive motor is provided at one end of the lifting screw 33 that passes through the portal frame 31. The output end of the drive motor is connected to the lifting screw 33, and the drive motor can control the lifting screw 33 to rotate in the forward or reverse direction.

[0033] In some embodiments, multiple fluoride ion absorption plates 2 are arranged perpendicular to the water flow direction in the wastewater tank 1, and the same number of lifting components 3 and quick-change components 4 are arranged in conjunction with the fluoride ion absorption plates 2. The arrangement of multiple sets of fluoride ion absorption plates 2, lifting components 3, and quick-change components 4 allows wastewater to pass through the fluoride ion absorption plates 2 multiple times after entering the wastewater tank 1, thereby collecting fluoride ions in the wastewater at multiple frequencies and further enhancing the collection effect of fluoride ions in the wastewater.

[0034] In some embodiments, multiple lifting covers 32 in the multiple lifting assemblies 3 are arranged to abut against each other, and the multiple lifting covers 32 are arranged to completely cover the top opening of the wastewater tank 1. The multiple lifting covers 32 are arranged without gaps, which can prevent debris from the external environment from entering the wastewater tank 1, and at the same time can prevent wastewater from splashing out or overflowing from the wastewater tank 1 and polluting the external environment.

[0035] In some embodiments, the height of the inlet 11 is set higher than the height of the outlet 12. Setting the inlet 11 higher can prevent the wastewater in the wastewater tank 1 from flowing back into the inlet 11 under the action of gravity, while setting the outlet 12 lower can use the gravity of the wastewater itself to accelerate the flow of wastewater in the wastewater tank 1.

[0036] In some embodiments, a pull ring 46 is provided at the end of the fixing pin 42 away from the snap-fit ​​groove 41 to facilitate the control of the fixing pin 42 by the staff.
