Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a defluorination device for defluorination resin. Background Technology

[0002] Fluorine is a trace element. Drinking water with low fluoride content is harmless and beneficial to the human body, but long-term consumption of water with a fluoride content greater than 1.5 mg / L can have adverse effects on the human body, and in severe cases, it can cause dental fluorosis and osteophyte disease. In some areas of my country, the fluoride content of regional water sources is greater than 1.0 mg / L, resulting in endemic fluorosis. The discharge of some high-concentration fluoride-containing industrial wastewater poses a great threat to human health, so it is necessary to treat fluoride-containing industrial wastewater.

[0003] Currently, the widely used calcium salt precipitation method is generally employed for treating medium- and high-concentration fluoride-containing wastewater. This method involves adding lime or calcium chloride to the wastewater, causing fluoride ions to react with calcium ions to form calcium fluoride. The precipitate is then separated from the water by filtration or natural sedimentation, achieving fluoride removal. While this method is effective, simple, convenient, and inexpensive, it is difficult to achieve complete removal in one step due to the particle properties and high solubility of the precipitate. The fluoride content in the treated wastewater often still exceeds standards, making it difficult to meet discharge requirements and potentially causing secondary pollution, which is detrimental to subsequent comprehensive utilization. To further reduce fluoride concentration, advanced defluorination technologies are needed. Ion exchange resins can adsorb fluoride ions in wastewater by exchanging ions with anions contained in the resin. This method offers advantages such as high selectivity, good treatment effect, stable effluent, and simple operation, making it suitable for treating low-concentration fluoride-containing wastewater.

[0004] However, for the ion exchange resin method, the resin needs to be replaced frequently to ensure the adsorption effect of fluoride ions. Otherwise, the resin will not be able to play its due adsorption role after adsorption saturation, resulting in excessive fluoride ions in the discharged wastewater. However, when replacing the resin, the machine must be stopped, which means that fluoride removal cannot be performed during the replacement.

[0005] Therefore, a defluorination device for defluorinating resin is proposed to address the above problems. Utility Model Content

[0018] 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5 As shown in the embodiment of this utility model, a defluorination device for defluorinating resin includes a main pipe 1, a pair of rotating rods 11 rotatably connected inside the main pipe 1; a blocking gate 12 is fixedly connected to the rotating rods 11; a pushing assembly 13 is provided at the end of the rotating rods 11; multiple filter boxes 14 are provided inside the main pipe 1; inlet 15 and outlet 18 are provided on both sides of the main pipe 1; an upper flow channel 16 and a lower flow channel 17 are provided inside the main pipe 1; during operation, the main pipe 1 is placed at the position where filtration is required, and the inlet 15 is connected to it. At this time, the water flows through the upper flow channel 16 and is filtered by the filter boxes 14 inside the upper flow channel 16. When the filter boxes 14 inside the upper flow channel 16 need to be replaced after long-term filtration, the pushing assembly is activated. 13. The pushing component 13 will drive the rotating rod 11 to rotate. When the rotating rod 11 rotates, it will drive the blocking door 12 to rotate. When the blocking door 12 rotates to the other side, the blocking door 12 will block the upper flow channel 16, thereby exposing the lower flow channel 17. At this time, the water will pass through the lower flow channel 17 and be filtered by the filter box 14 in the lower flow channel 17, and flow out from the outlet 18. At this time, the filter box 14 in the upper flow channel 16 can be replaced. Thus, the rotation of the blocking door 12 driven by the rotating rod 11 can transfer the flow channel of wastewater from the upper flow channel 16 to the lower flow channel 17. After the filter box 14 in the upper flow channel 16 or the lower flow channel 17 needs to be replaced due to long-term filtration, it can be replaced without affecting the filtration of wastewater.

[0021] like Figures 1 to 3 As shown, the pushing component 13 includes a cylinder 2; the output end of the cylinder 2 is rotatably connected to a telescopic rod 21; multiple telescopic rods 21 are provided; the other end of the telescopic rod 21 is fixedly connected to the rotating rod 11; during operation, when switching the flow channels of the upper flow channel 16 and the lower flow channel 17, the cylinder 2 is activated. Since the output end of the cylinder 2 rotates with the telescopic rod 21, when the cylinder 2 is activated, the output end of the cylinder 2 will drive the telescopic rod 21 to move downward. At the same time, the telescopic rod 21 will extend and retract inward, and the other end of the telescopic rod 21 will drive the rotating rod 11 to rotate, thereby realizing the switching of the upper flow channel 16 and the lower flow channel 17; thus, the switching operation of the upper flow channel 16 and the lower flow channel 17 can be easily realized by activating the cylinder 2.

[0022] like Figures 1 to 5As shown, an arc-shaped rack 3 is slidably connected to the surface of the main pipe 1; multiple arc-shaped racks 3 are provided; multiple L-blocks 31 are fixedly connected to the inner wall of the arc-shaped rack 3; round blocks 32 are fixedly connected to the side wall of the L-blocks 31; a round groove 33 is opened on one side of the filter box 14; the round blocks 32 and the round groove 33 are correspondingly arranged; a pair of fixing rods 34 are fixedly connected to the main pipe 1; a gear 35 is rotatably connected to the fixing rods 34; the gear 35 is correspondingly arranged to the arc-shaped rack 3; a fixing component 36 is provided on the main pipe 1; the fixing component 36 is correspondingly arranged to the gear 35; during operation, by rotating the gear 35, the gear... The gear 35 meshes with the inner wall teeth of the arc-shaped rack 3, causing the arc-shaped rack 3 to move on the surface of the main pipe 1. After replacing the filter box 14, the filter box 14 is placed into the main pipe 1. At this time, the gear 35 will drive the L block 31 to move until the round block 32 enters the round groove 33 of the filter box 14, achieving engagement and fixing the filter box 14. When replacement is needed, simply rotate the gear 35 to move the round block 32 out of the round groove 33, remove the filter box 14, and then fix the gear 35 through the fixing component 36. Thus, the movement of the arc-shaped rack 3 by the gear 35 achieves the fixing effect of the filter box 14.

[0023] like Figures 1 to 5 As shown, the fixing component 36 includes a fixing block 4; the fixing block 4 is threadedly connected to a moving rod 41; an arc-shaped toothed block 42 is fixedly connected to the end of the moving rod 41; the arc-shaped toothed block 42 is correspondingly arranged with the gear 35; during operation, after the gear 35 is rotated, the moving rod 41 can be rotated to move the moving rod 41 forward, driving the arc-shaped toothed block 42 forward until the arc-shaped toothed block 42 engages with the gear 35; thus, the arc-shaped toothed block 42 completes the fixing function of the gear 35, preventing the filter box 14 from loosening due to the gear 35.

[0024] like Figure 4 As shown, a groove 5 is provided inside the filter box 14; a spring 52 is fixedly connected inside the circular groove 33; a sliding rod 51 is fixedly connected to one end of the spring 52; the sliding rod 51 is located inside the groove 5 and is slidably connected to the groove 5; a protrusion 53 is fixedly connected to the bottom of the sliding rod 51; during operation, when the circular block 32 moves into the circular groove 33, the circular block 32 contacts the protrusion 53 in the circular groove 33 and simultaneously squeezes the protrusion 53, causing the protrusion 53 to drive the sliding rod 51 to move upward in the groove 5, so that the sliding rod 51 is exposed outside the filter box 14. After the circular block 32 is removed, the sliding rod 51 will be affected by the reset effect of the spring 52 and enter the groove 5; thus, the fixing of the filter box 14 can be determined by observing the sliding rod 51.

[0025] like Figures 1 to 3As shown, an arc-shaped sealing strip 6 is fixedly connected to the end of the blocking door 12; the arc-shaped sealing strip 6 is arc-shaped; during operation, when wastewater flows, the arc-shaped sealing strip 6 can increase the seal between the blocking door 12 and the main pipe 1, preventing water leakage between the blocking door 12 and the main pipe 1; thus, the arc-shaped sealing strip 6 prevents water leakage between the blocking door 12 and the main pipe 1.

[0026] Working principle: By placing the main pipe 1 at the location requiring filtration and connecting it to the inlet 15, the water flows through the upper channel 16 and is filtered by the filter box 14 within it. When the filter box 14 in the upper channel 16 needs replacement after prolonged filtration, the push assembly 13 is activated. The push assembly 13 drives the rotating rod 11 to rotate, which in turn drives the blocking gate 12 to rotate until it rotates to the other side. At this point, the blocking gate 12 blocks the upper channel 16, thus exposing the lower channel 17, through which the water flows. The water is filtered by the filter box 14 in the lower channel 17 and flows out from the outlet 18. At this time, the filter box 14 in the upper channel 16 can be replaced. When switching between the upper channel 16 and the lower channel 17, the cylinder 2 is activated. Since the output end of the cylinder 2 rotates with the telescopic rod 21, when the cylinder 2 is activated, the output end of the cylinder 2 will drive the telescopic rod 21 to move downward. At the same time, the telescopic rod 21 will extend and retract inward, and the other end of the telescopic rod 21 will drive the rotating rod 11 to rotate, thereby realizing the switching between the upper channel 16 and the lower channel 17. By rotating the gear 35, the gear 35 will interact with the toothed blocks on the inner wall of the arc-shaped rack 3. The gear 35 meshes with the filter box 14, causing the arc-shaped rack 3 to move on the surface of the main pipe 1. After replacing the filter box 14, the filter box 14 is placed into the main pipe 1. At this time, the gear 35 will drive the L block 31 to move until the round block 32 enters the round groove 33 of the filter box 14, achieving engagement and fixing the filter box 14. When replacement is needed, simply rotate the gear 35 to move the round block 32 out of the round groove 33, remove the filter box 14, and then fix the gear 35 with the fixing component 36. After rotating the gear 35, the moving rod 41 can be rotated to move the moving rod 41 forward. The arc-shaped toothed block 42 moves forward until it engages with the gear 35. When the moving block 32 enters the circular groove 33, the block 32 contacts the protrusion 53 in the circular groove 33 and simultaneously squeezes the protrusion 53, causing the protrusion 53 to drive the sliding rod 51 to move upward in the groove 5, so that the sliding rod 51 is exposed in the filter box 14. After the block 32 is removed, the sliding rod 51 will be affected by the reset effect of the spring 52 and enter the groove 5. When the wastewater flows, the arc-shaped sealing strip 6 can increase the seal between the barrier door 12 and the main pipe 1, preventing water leakage between the barrier door 12 and the main pipe 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
