Embodiment 1

[0022] A method for preparing a fluoride-removing filter material, the method comprising the following steps:

[0023] Step 1. Put 2kg of NDA900 type resin raw materials into the filter car, add 2kg of methanol solution, stir intermittently at 45°C, let it stand for 1 hour, then filter out the methanol solution by gravity filtration, return the filtered methanol solution to the distillation system for distillation and repeat Use; then the resin is transferred to a vacuum dryer, heated to 60°C with a water bath, while maintaining a vacuum of 0.2MPa, and unloaded when the water content is reduced to 15%, to obtain a cleaned NDA900 resin; step 2, in Add 2Kg anhydrous FeCl to the 6L reactor 3 and 20% hydrochloric acid to make 3LFeCl 3 solution, wherein the equivalent iron weight content is 10%, and the pH value is 2; the NDA900 type resin after washing, drying and pretreatment is added in batches at a feeding rate of no more than 1 / 10 of the resin addition amount within 15 minute...

Embodiment 2

[0025] Step 2, add 2Kg anhydrous FeCl in 6L reactor 3 and 20% hydrochloric acid to make 3LFeCl 3 solution, wherein the equivalent iron weight content is 10%, and the pH value is 2; the NDA900 type resin after washing, drying and pretreatment is added in batches at a feeding rate of no more than 1 / 10 of the resin addition amount within 15 minutes. 3 In the reaction kettle of the solution, NDA900 type resin and FeCl 3 The solid-to-liquid weight ratio of the solution is 1:1. At 35°C, keep stirring for 2 hours to prepare the FeCl-loaded 4 - Strongly basic anion resin intermediate; All the other steps are with embodiment 1.

Embodiment 3

[0027] Step 2, add 2Kg anhydrous FeCl in 6L reactor 3 and 20% hydrochloric acid to make 3LFeCl 3 solution, wherein the equivalent iron weight content is 10%, and the pH value is 2; the NDA900 type resin after washing, drying and pretreatment is added in batches at a feeding rate of no more than 1 / 10 of the resin addition amount within 15 minutes. 3 In the reaction kettle of the solution, NDA900 type resin and FeCl 3 The solid-to-liquid weight ratio of the solution is 2:1, and at 35°C, keep stirring for 2 hours to prepare FeCl-loaded 4 - Strongly basic anion resin intermediate; All the other steps are with embodiment 1.

Abstract

The invention discloses a cup cover spiral stirring type defluorination filtering cup which comprises a cup cover and a cup body, wherein the cup cover is provided with a defluorination device; the defluorination device comprises a motor, a telescopic rod and a defluorination filtering box; the motor is arranged at the bottom of the cup cover; the defluorination filtering box is connected with themotor through the telescopic rod, and then the defluorination filtering box is driven to rotate through the motor; the defluorination filtering box comprises a box body and a box cover. When the water level inside the cup is too low, the defluorination filtering box is soaked into a water body through the telescopic rod, filtering holes are uniformly formed in the surfaces of the box body and thebox cover, spiral outer ribs are arranged on the outer surface of the box body, and the defluorination filtering box is filled with a defluorination filtering material.

Description

technical field [0001] The invention relates to a cup cover spiral stirring type defluoridation filter water cup. Background technique [0002] Fluoride is an essential trace element for human life activities. Low concentrations can protect teeth, prevent dental caries, and promote bone development, but if you drink high-concentration water for a long time, you will have skeletal fluorosis, dental fluorosis and other diseases. Generally, the concentration of fluoride in surface water is relatively low, which is at trace level, but the concentration of fluoride in groundwater is relatively high. my country is one of the countries with serious endemic fluorosis. In order to ensure the safety of drinking water, the national "Drinking Water Sanitation Standard" (GB5749-2006) stipulates that the fluoride content in drinking water should be less than 1.0mg / L, so drinking water exceeding 1.0mg / L must be defluoridated Treatment, water cups are frequently used drinking utensils, a...
