Embodiment 1

[0020] A method for preparing a fluoride-removing filter material, the method comprising the following steps:

[0021] 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

[0023] 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

[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 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 spiral fluorine-removing filter water cup. The spiral fluorine-removing filter water cup comprises a cup cover and a cup body, the cup body is provided with a fluorine-removing device, the fluorine-removing device comprises a motor, a telescopic rod and a fluorine-removing filter box, the motor is arranged at the inner bottom of the cup body, the fluorine-removing filterbox is connected to the motor through the telescopic rod so that the motor can drive the fluorine-removing filter box to rotate, the fluorine-removing filter box comprises a box body and a box cover,filter holes are formed in the surfaces of both the box body and the box cover, the outer surface of the box body is provided with spiral outer ribs, and the fluorine-removing filter box is filled with a fluorine-removing filter. As the built-in fluorine-removing device of the spiral fluorine-removing filter water cup comprises the motor, the telescopic rod and the fluorine-removing filter box, the fluorine-removing filter box can be driven to rotate by the motor and the flow of water can be effectively driven so as to improve the effect of adsorbing fluorine ions; as the outer surface of thebox body is provided with the spiral outer ribs, the spiral structure, when it rotates, can agitate the upper and lower convection of the water so as to improve the water filtration efficiency.

Description

technical field [0001] The invention relates to a spiral 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, and the efficient de...
