Description

Technical Field

[0001] This utility model relates to a defluoridation water treatment device. Background Technology

[0002] Fluorine is one of the essential trace elements for the human body. Adequate fluorine intake is beneficial for bone strength and can prevent tooth decay. However, excessive fluorine absorption can cause significant harm to human health, far exceeding the effects of fluorine deficiency. Excessive fluoride in drinking water can lead to fluorosis. Numerous studies have shown that the adverse effects of fluorides on the human body generally include biochemical effects, acute poisoning, and long-term chronic poisoning.

[0003] Defluoridation refers to the process where raw water flows through the filter media in a defluoridator. Through contact between the raw water and the filter element, the filter element adsorbs the fluoride in the water, allowing the fluoride ions in the water to be adsorbed and exchanged by the filter media. In this way, the fluoride ions in the water are removed, and the fluoride content in the water is effectively reduced.

[0004] Existing defluorination equipment can only statically remove fluoride from liquids, resulting in low efficiency and inability to completely remove fluoride from liquids. This increases the time required for defluorination, consumes a lot of manpower, and is not only inefficient but also requires replacing the defluorination filter element, which is inconvenient and affects efficiency.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of defluoridation water treatment device with greater industrial application value. Utility Model Content

The left half-annular step and the right half-annular step are respectively connected to the left and right sides of the outlet pipe by a rotating shaft, and the opposite left half-annular step and right half-annular step are interlocked.

[0011] Preferably, in the defluoridation water treatment device, at least three adsorption filter elements are provided, which are stacked inside the liquid outlet pipe.

[0012] Preferably, in the defluoridation water treatment device, the adsorption filter element is provided with 4.

[0025] Example

[0026] like Figure 1 and Figure 2 As shown, a defluoridation water treatment device includes a treatment tank 1. A first partition 2 and a second partition 3 are connected inside the treatment tank 1. The first partition 2 and the second partition 3 divide the treatment tank 1 into a first treatment tank 4, a second treatment tank 5, and a third treatment tank 6. A dosing tank 7 and a stirring assembly 8 are connected above the first treatment tank 4, the second treatment tank 5, and the third treatment tank 6. A first water pumping and filtering assembly 9 is connected between the first treatment tank 4 and the second treatment tank 5. A second water pumping and filtering assembly 10 is connected between the second treatment tank 5 and the third treatment tank 6.

[0027] Furthermore, this utility model is designed for pumping and filtering water in different treatment tanks. The specific structure is as follows: the first pumping and filtering assembly 9 and the second pumping and filtering assembly 10 have the same structure. The first pumping and filtering assembly 9 includes a pumping pump 91. The inlet of the pumping pump 91 is connected to the inlet pipe 92, and the outlet of the pumping pump 91 is connected to the outlet pipe 93. An annular step 94 is connected to the outlet of the outlet pipe 93. An adsorption filter element 95 is filled in the outlet pipe 93 and is connected to the annular step 94.

[0028] Furthermore, to facilitate quick and easy replacement of the adsorption filter element (which uses activated carbon), the specific structure is as follows: the annular step 94 is composed of a left half-annular step 96 and a right half-annular step 97. The left half-annular step 96 and the right half-annular step 97 are respectively connected to the left and right sides of the liquid outlet pipe 93 via a rotating shaft, and the corresponding left half-annular step 96 and right half-annular step 97 are interlocked.

[0029] By connecting the left semi-circular step 96 and the right semi-circular step 97 through a snap-fit ​​method, the technology can ensure the fixation of the column adsorption filter element and also ensure quick replacement of the adsorption filter element.

[0030] For the secondary filtration of defluorination, at least three adsorption filter elements 95 are provided, which are stacked inside the liquid outlet pipe. In this invention, four adsorption filter elements 95 are used, and they are all filled into the liquid outlet pipe by perforated sleeves, which can serve to fix them and also allow for quick replacement in one go.

[0031] Furthermore, the waste liquid in the treatment tank is stirred. The specific structure is as follows: the stirring assembly 8 includes a stirring motor 81, the drive shaft of the stirring motor 81 is connected to a stirring shaft 82 that extends into the corresponding treatment tank, and stirring blades 83 are connected to the stirring shaft 82.

[0032] Specifically, by stirring, the defluorinating agent and the waste liquid can be thoroughly mixed, so that the defluorinating agent added from the dosing tank can fully react with the fluorine in the waste liquid, thereby reducing the fluorine content.

[0033] The dosing tank of this invention is connected to an automatic dosing device (a device known to those skilled in the art), and quantitative dosing is achieved through a control device. This control device, which is electrically controlled in conjunction with the stirring assembly 8, the dosing tank 7, and the water pumping and filtering assembly, is a PLC. Quantitative dosing can be programmed according to pre-defined requirements by those skilled in the art.

[0034] A quantitative dosage (defined by those skilled in the art) can react with the fluoride in the waste liquid and ensure a thorough reaction through a stirring assembly, thereby improving efficiency.

[0035] The liquid inlet of the liquid inlet pipe 92 described in this utility model is connected to a filter screen, which can filter out some impurities in the waste liquid.

[0036] The working principle of this utility model is as follows:

[0037] In practice, the waste liquid is introduced into the first treatment tank through the inlet. Then, a certain amount of defluorinating agent is added to the waste liquid in the first treatment tank through the automatic dosing device in the dosing tank. After thorough stirring, the thoroughly stirred waste liquid is collected into the second treatment tank through the first water pumping and filtration assembly. The same operation is carried out until the defluorinated waste liquid enters the third treatment tank. After the final defluorination treatment, the waste liquid is collected.

[0038] In the above operation process, a certain amount of defluorinating agent can remove a portion of the fluoride from the waste liquid, and then further defluorination is carried out through the water pumping and filtration components. This process is repeated to ensure that defluorination is carried out while improving the efficiency of defluorination.

They are used only for the convenience of describing this application and for 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 application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
