At present, many studies have been conducted on the treatment technology of high-concentration fluoride wastewater at home and abroad. The main methods of fluoride removal from water include chemical precipitation, coagulation sedimentation, adsorption and ion exchange, electrocoagulation and electrodialysis. The main fluoride removal reagents include lime, aluminum sulfate, aluminum chloride, bone char, zeolite, zirconium oxide and activated alumina.

[0003] As disclosed in application number CN202023027617.2, a dosing mechanism for a fluoride-containing wastewater treatment device includes a dissolving tank and two sets of dosing pipelines connected to the rear of the dissolving tank. One side of the dissolving tank is connected to a municipal water pipe, and a first butterfly valve is installed on the municipal water pipe. A first stirring motor is installed on the upper part of the dissolving tank, and the stirring shaft of the first stirring motor is located inside the dissolving tank. A dosing box is also installed on the dissolving tank. An outlet is provided at the bottom of the dissolving tank, and a third butterfly valve is connected to the outlet. The third butterfly valve is connected to a first dosing pipeline and a second dosing pipeline arranged in parallel.

[0004] However, existing equipment suffers from poor adaptability to complex water quality, and the dosing system of the equipment relies heavily on fixed dosing patterns, resulting in serious waste of chemicals. Utility Model Content

[0027] Example 1, combined with Figures 1-3 Explanation:

[0028] A dry dosing device includes: a dosing tank 1, a storage tank 2, a solid chemical agent 3, a lifting spring assembly 4, a pushing assembly 5, and a water quality monitoring assembly 6. The dosing tank 1 and the storage tank 2 are arranged side by side upstream of a water pipe 7. Multiple sets of solid chemical agents 3 are provided and stacked on the upper side of the lifting spring assembly 4. By setting the solid chemical agents 3 and the storage tank 2, the initial dosing amount can be calculated based on the system water volume and then added at once. The dosing device is then guided to accurately add the chemical agent based on the water quality monitoring results.

[0029] The lifting spring assembly 4 is installed inside the medicine storage tank 2. By setting the lifting spring assembly 4, a sufficient amount of solid medicine 3 can be pre-filled, which solves the problem of difficult medicine handling and delivery.

[0030] The pusher assembly 5 is located on one side of the storage tank 2. The storage tank 2 has an opening on the side near the pusher assembly 5. The output end of the pusher assembly 5 passes through the opening and works with the uppermost solid agent 3. The pusher assembly 5 can automatically push the solid agent 3 into the dosing tank 1. The pusher assembly 5 facilitates automated drug dosing.

[0031] The water quality monitoring component 6 is installed downstream of the water pipe 7. By installing the water quality monitoring component 6, it is possible to monitor the water in the water pipe in real time and adjust the dosage of the reagent in a timely manner.

[0032] The solid drug 3 is made by mixing and pressing liquid drug raw materials into tablets. This design can improve the stability of the drug and prevent leakage.

[0033] The top block 53 is equipped with a rubber buffer pad at its front end to reduce the impact and wear generated when pushing the solid medicine 3.

[0034] The top of the medicine storage tank 2 is equipped with a removable sealing cover, which facilitates the replenishment of solid medicine 3 and the maintenance of internal components.

[0035] Example 2, based on Example 1, combined with... Figure 4 Explanation:

[0036] The lifting spring assembly 4 includes: a top plate 41, a compression spring 42, and an annular sliding plate 43. The annular sliding plate 43 is fixedly installed on the lower side of the top plate 41 and slidably disposed inside the medicine storage tank 2. The upper end of the compression spring 42 is fixedly connected to the lower side of the top plate 41, and the lower end of the compression spring 42 is fixedly connected to the bottom surface of the medicine storage tank 2. Stacked solid medicines 3 are placed on the upper side of the top plate 41.

[0037] The inner wall of the medicine storage tank 2 is provided with a guide groove, and the annular slide plate 43 slides up and down along the guide groove to ensure that the lifting spring assembly 4 remains vertically stable during compression and reset.

[0038] In use, the top plate 41 can slide up and down inside the medicine storage tank 2 via the annular sliding plate 43. The compression spring 42 is used to give the top plate 41 an upward thrust, thereby ensuring that there is always solid medicine 3 on the top layer, so as to be pushed into the medicine dosing tank 1 in conjunction with the medicine pushing assembly 5.

[0039] Example 3, based on Example 2, combined with Figure 5 Explanation:

[0040] The drug pushing assembly 5 includes: a raised box 51, a cylinder 52 and a top block 53. The raised box 51 is fixedly installed on one side of the drug storage tank 2, the cylinder 52 is fixedly installed on the raised box 51, and the output end of the cylinder 52 is fixedly connected to the top block 53. The top block 53 is used in conjunction with the uppermost solid drug 3.

[0041] With this configuration, the raised box 51 can position the cylinder 52 at the top layer of solid agent 3, so that starting the cylinder 52 can push the solid agent 3 into the dosing tank 1. The top block 53 is used to completely push the solid agent 3 into the dosing tank 1.

[0042] The water quality monitoring component 6 includes: a probe-type concentration meter 61, a probe-type pH meter 62, a probe-type conductivity meter 63, and an ORP meter 64, which are arranged in parallel downstream of the water pipe 7.

[0043] This setup, using a parallel configuration, allows all probes to measure the same water sample at almost the exact same time point, improving the accuracy of the measurement data.

[0044] The working principle of this utility model is as follows: During use, the initial dosage is calculated based on the system water volume. Then, cylinder 52 is activated, and top block 53 pushes the top layer of solid agent 3 into the dosing tank 1. The lower layer of solid agent 3 moves to the top layer through top plate 41. Top block 53 continues to work, pushing the top layer of solid agent 3 into the dosing tank 1 until the dosage is met. Subsequently, the dosing device accurately adds the agent based on the results detected by water quality monitoring component 6. This utility model has a reasonable structure and is easy to use. It can effectively solve the problems of difficult agent handling and leakage, making it safer and more accurate when used on site.
