Description

Technical Field

[0001] This utility model relates to the field of defluorination device technology, and in particular to a defluorination device for fluoride-containing wastewater. Background Technology

[0002] Defluoridation refers to removing excess fluoride from wastewater or raw water to meet specified process requirements. The impact of fluoride ions in drinking water on human health depends primarily on the fluoride ion content.

[0003] When the fluoride content in water is too low, it can easily lead to tooth decay; when it is too high, it can easily lead to dental fluorosis, skeletal fluorosis, and other diseases. Therefore, it is necessary to clean and control the fluoride in water to meet discharge or drinking standards. However, existing devices that use a single chemical precipitation or adsorption method for cleaning are prone to excessive fluoride and impurity residues. Furthermore, using them in combination is not convenient for replacing or cleaning the adsorption components.

[0004] Therefore, we provide a fluoride removal device for fluoride-containing wastewater. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a fluoride removal device for fluoride-containing wastewater, achieving efficient fluoride removal and facilitating the maintenance and replacement of adsorption components.

[0006] In view of this, the present invention provides a fluoride removal device for fluoride-containing wastewater, including a rotating support column and an adjusting rotating motor fixedly installed on the upper end of the rotating support column. The output end of the adjusting rotating motor is fixedly connected to the rotating support column. A rotating gear disk is provided between the adjusting rotating motor and the rotating support column. The rotating gear disk is fixedly installed outside the output end of the adjusting rotating motor. The rotating gear disk is meshed with several rotating gears. A snap-fit ​​post is fixedly connected to the lower end of the rotating gear. A rotating threaded post is inserted into the snap-fit ​​post. Several adsorption support plates are threadedly connected to the outer side of the rotating threaded post. A bottom rotating motor is fixedly connected to the lower end of the rotating support column.

[0007] Preferably, a rotating support ring is provided in the middle of a plurality of rotating gears, and an adjusting support cylinder is rotatably connected to the inner wall of the rotating support ring. The adjusting support cylinder is threadedly connected to the output end of the adjusting rotating motor.

[0008] Preferably, a plurality of support rods are fixedly connected to the outer side of the rotating support ring, and the support rods are rotatably connected to the rotating gear through rotating support rods, and the support rods are fixedly connected to the rotating support rods.

[0009] Preferably, a limiting telescopic rod is fixedly connected to the upper end of the support rod, and a limiting support cylinder is slidably connected to the upper end of the limiting telescopic rod.

[0010] Preferably, the limiting support cylinder is fixedly connected to the adjusting rotation motor, and the output end of the adjusting rotation motor is located between several limiting support cylinders.

[0011] Preferably, the adsorption support plate is slidably connected to the movable support block by a movable support block and has a movable limiting groove. The adsorption support plate is fixedly connected to the movable support block, and the movable limiting groove is opened on the outside of the rotating support column.

[0012] Preferably, a bottom support frame is rotatably connected to the lower end of the rotating threaded column, and the bottom support frame is fixedly connected to the rotating support column.

[0013] Compared with the prior art, this utility model provides a fluoride removal device for fluoride-containing wastewater, which has the following beneficial effects:

[0014] This invention utilizes a bottom-mounted rotating motor to drive a rotating support column and multiple adsorption support plates on its outer side to rotate, thereby stirring and mixing the wastewater and added chemical substances such as calcium chloride, calcium hydroxide, and calcium oxide inside the device. Furthermore, by equipping the adsorption support plates with an adsorbent made of resin or similar material, the device can absorb and reprocess impurities generated after the stirring and defluorination process, as well as any incompletely treated fluoride, thus improving the defluorination efficiency of the device.

[0015] This invention stops the bottom rotating motor and allows the adjusting rotating motor above the rotating support column to rotate, causing the rotating gear disk at its output end to rotate simultaneously. This causes multiple rotating gears on the outside of the rotating gear disk to rotate the locking column below inside the rotating threaded column under meshing support. Thus, the rotation of the rotating threaded column achieves the effect of moving the height of multiple adsorption support plates on the outside of the rotating threaded column.

[0016] This invention facilitates the replacement and cleaning of the adsorbent inside the adsorption support plate and the plate itself, thereby improving the efficiency of cleaning the device and the convenience of maintenance and cleaning.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: A fluoride removal device for fluoride-containing wastewater, such as... Figures 1-4As shown, the device includes a rotating support column 1 and an adjusting rotating motor 2 fixedly mounted on the upper end of the rotating support column 1. The output end of the adjusting rotating motor 2 is fixedly connected to the rotating support column 1. A rotating gear disk 3 is provided between the adjusting rotating motor 2 and the rotating support column 1. The rotating gear disk 3 is fixedly mounted outside the output end of the adjusting rotating motor 2. Several rotating gears 10 are meshed with the rotating gear disk 3. A snap-fit ​​post 11 is fixedly connected to the lower end of the rotating gears 10. A rotating threaded post 12 is inserted into the snap-fit ​​post 11. Several adsorption support plates 13 are threadedly connected to the outer side of the rotating threaded post 12. A bottom rotating motor 17 is fixedly connected to the lower end of the rotating support column 1. When the device is running, the rotating support column 1 and the multiple adsorption support plates 13 on its outer side are rotated by the operation of the bottom rotating motor 17, thereby achieving the adsorption of wastewater and added chemicals such as calcium chloride, calcium hydroxide, and calcium oxide inside the device. The substances are stirred and mixed, and by providing an adsorbent of resin material inside the adsorption support plate 13, impurities generated after stirring and defluorination, as well as incompletely treated fluorine, can be absorbed and retreated, improving the defluorination efficiency of the device. By stopping the bottom rotating motor 17, the adjusting rotating motor 2 above the rotating support column 1 is rotated, causing the rotating toothed disk 3 at its output end to rotate simultaneously. This causes multiple rotating gears 10 on the outside of the rotating toothed disk 3 to drive the locking column 11 below to rotate inside the rotating threaded column 12 under meshing support. This rotation of the rotating threaded column 12 achieves the effect of moving the height of multiple adsorption support plates 13 on the outside of the rotating threaded column 12, facilitating the replacement and cleaning of the adsorbent inside the adsorption support plate 13 and the plate itself, improving the efficiency of device cleaning and the convenience of maintenance and cleaning.

[0026] like Figures 1-4 As shown, a rotating support ring 5 is provided in the middle of several rotating gears 10. An adjusting support cylinder 4 is rotatably connected to the inner wall of the rotating support ring 5. The adjusting support cylinder 4 is threadedly connected to the output end of the adjusting rotating motor 2. Several support rods 6 are fixedly connected to the outer side of the rotating support ring 5. The support rods 6 are rotatably connected to the rotating gears 10 through rotating support rods 9. The support rods 6 and rotating support rods 9 are fixedly connected. By rotating the adjusting support cylinder 4 under the support of the adjusting rotating motor 2, and by the rotating connection between the rotating support ring 5 and the adjusting support cylinder 4, the height of the support rods 6 and the rotating support ring 5 can be adjusted. This allows the rotating gear 10 on one side and the locking pin 11 to move simultaneously under the connection of the rotating support rod 9. Furthermore, by rotating the rotating support rod 9 to support the rotating gear 10, the stability of the rotating gear 10 when moving to a fixed position is ensured, and the reliability of the rotating gear 10 when rotating is guaranteed.

[0027] like Figures 1-4As shown, a limiting telescopic rod 7 is fixedly connected to the upper end of the support rod 6, and a limiting support cylinder 8 is slidably connected to the upper end of the limiting telescopic rod 7. The limiting support cylinder 8 is fixedly connected to the adjusting rotation motor 2, and the output end of the adjusting rotation motor 2 is located between several limiting support cylinders 8. With the support of the adjusting rotation motor 2 and the limiting support cylinders 8, the limiting telescopic rod 7 slides as the support rod 6 moves. With the limiting support of the adjusting rotation motor 2 and the limiting support cylinders 8, the stability and efficiency of the support rod 6 and the components on both sides when moving are ensured, and the accuracy of the operation when multiple components are connected is ensured.

[0028] Example 2: A fluoride removal device for fluoride-containing wastewater, such as... Figures 1-4 As shown, the adsorption support plate 13 is slidably connected to the movable support block 14 with a movable limiting groove 15. The adsorption support plate 13 and the movable support block 14 are fixedly connected. The movable limiting groove 15 is opened on the outside of the rotating support column 1. With the support of multiple movable limiting grooves 15 opened on the outside of the rotating support column 1, the position movement of the movable support block 14 can be limited and guided when the adsorption support plate 13 moves in height. This achieves the effect of controlling the movement direction of the adsorption support plate 13 and improving its movement accuracy and stability.

[0029] like Figures 1-4 As shown, a bottom support frame 16 is rotatably connected to the lower end of the rotating threaded column 12. The bottom support frame 16 is fixedly connected to the rotating support column 1. By rotating and supporting the bottom support frame 16 on one side, the rotating threaded column 12 is rotated and supported, thereby ensuring the stability of the device when it rotates.

[0030] Working Principle: The rotating support column 1 and its outer multiple adsorption support plates 13 are rotated by the bottom rotating motor 17, which stirs and mixes the wastewater and added chemicals such as calcium chloride, calcium hydroxide, and calcium oxide inside the device. The adsorption support plates 13 are filled with an adsorbent made of resin, which absorbs and re-treats impurities generated after the defluorination process and any incompletely treated fluorine, improving the defluorination efficiency of the device. When the bottom rotating motor 17 stops rotating, the adjusting rotating motor 2 above the rotating support column 1 rotates, causing the rotating gear disk 3 at its output end to rotate simultaneously. This causes the multiple rotating gears 10 on the outer side of the rotating gear disk 3 to rotate the locking column 11 below inside the rotating threaded column 12 under meshing support. The rotation of the rotating threaded column 12 achieves the effect of moving the height of the multiple adsorption support plates 13 outside the rotating threaded column 12, facilitating the replacement and cleaning of the adsorbent inside the adsorption support plates 13 and the plates themselves, improving the efficiency of the device cleaning and the convenience of maintenance.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
