Description

Technical Field

[0001] This utility model relates to the field of water purification system technology, and in particular to a pure water device. Background Technology

[0002] In boiler operation, using pure water as the supply water is a key strategy for improving efficiency and maintaining equipment. It can significantly reduce internal scaling and ensure cleanliness, thereby improving thermal efficiency. Currently common pure water supply methods, such as the "pure water device" disclosed in announcement number CN104445668B, mainly rely on the pretreatment of raw water through a filter tank and separation through a reverse osmosis membrane to produce concentrated water and pure water. However, the purity of the pure water produced by this method often has certain limitations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pure water device that can improve the purity of pure water without changing the original pure water device as much as possible.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pure water device, including a filter tank group and a dosing mechanism; the dosing mechanism includes a feed hopper and a dosing tank, and the discharge end of the feed hopper is connected to the inner cavity of the dosing tank;

[0005] The bottom of the dosing tank is provided with an output pipe that connects to its own internal cavity. The output pipe is connected to the filter tank assembly. The internal cavity of the dosing tank is provided with a receiving pipe that is rotated. The receiving pipe has an inlet end and a closed end. The inlet end of the receiving pipe is connected to the outlet end of the feed hopper. The weight of the closed end is greater than the weight of the inlet end. The closed end and the inlet end are located on different vertical lines.

[0006] Furthermore, the inner cavity of the dosing tank is rotatably provided with a rotating shaft, and the dosing tube is connected to the shaft body of the rotating shaft.

[0007] Furthermore, the tube body of the receiving tube is welded to the shaft body of the rotating shaft.

[0008] Furthermore, the dosing mechanism also includes a mixing tank; the output pipe of the dosing tank is connected to the inner cavity of the mixing tank, and the mixing tank is connected to the filter tank assembly.

[0009] Furthermore, the feed hopper is equipped with a flow regulating valve, which is used to control the output flow rate at the feed hopper outlet.

[0010] Furthermore, the filter tank assembly includes a media filter tank, an activated carbon filter tank, and a security filter connected in sequence. A dosing mechanism is connected to the liquid inlet pipe of the media filter tank, a dosing mechanism is connected to the connecting pipe between the media filter tank and the activated carbon filter tank, and a dosing mechanism is connected to the connecting pipe between the activated carbon filter tank and the security filter.

[0011] Furthermore, the bottom of the inner cavity of the dosing tank is inclined toward the feed end of the output pipe.

[0012] Furthermore, the outlet end of the filter tank assembly is connected to a reverse osmosis unit.

[0013] The beneficial effects of this invention are as follows: the chemical solution is injected into the dosing tank through the feed hopper, and then flows into the receiving pipe below it. When the chemical solution in the receiving pipe reaches the set amount, the receiving pipe automatically flips, causing the chemical solution to pour into the output pipe. In this way, the chemical solution can enter the water flow pipeline system of the pure water device intermittently and in batches to assist the filter tank group in completing the purification process of the raw water, thereby obtaining a high purity of pure water.

[0022] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to Figure 1 and Figure 2As shown, this utility model discloses a pure water device, including a filter tank assembly 1 and a dosing mechanism 2. The dosing mechanism 2 includes a feed hopper 21 and a dosing tank 22. The discharge end of the feed hopper 21 is connected to the inner cavity of the dosing tank 22. The bottom of the dosing tank 22 is provided with an output pipe 221 that connects to its own inner cavity. The output pipe 221 is connected to the filter tank assembly 1. The inner cavity of the dosing tank 22 is provided with a dosing pipe 222 that is rotated. The dosing pipe 222 has an inlet end and a closed end. The inlet end of the dosing pipe 222 is connected below the discharge end of the feed hopper 21. The weight of the closed end is greater than the weight of the inlet end. The closed end and the inlet end are located on different vertical lines.

[0024] Working principle: During the dosing process, since the weight of the closed end of the dosing pipe is greater than the weight of the inlet end, the height of the inlet end is higher than the height of the closed end. The relevant medicine is poured into the feed hopper 21. The medicine enters the dosing pipe 222, which is in the dosing state, through the feed hopper 21. As the medicine continuously enters the dosing pipe 222, when the medicine in the dosing pipe 222 reaches the set amount, that is, when the weight of the inlet end of the dosing pipe 222 exceeds the counterweight of the closed end, the dosing pipe 222 loses its balance and flips over, thereby pouring the medicine into the output pipe 221. Then, the medicine enters the water flow pipeline system of the pure water device through the output pipe 221 to assist the filter tank group 1 in completing the purification process of the raw water, thereby obtaining a high purity of pure water.

[0025] Specifically, if a dosing mechanism 2 is installed on the inlet pipe of the media filter tank 11, the liquid poured into the feed hopper 21 can be either an inorganic flocculant or an organic flocculant.

[0026] If a dosing mechanism 2 is connected to the connecting pipe between the media filter tank 11 and the activated carbon filter tank 12, the liquid medicine poured into the feed hopper 21 can be a nitrite reducing agent such as sodium binitrite or sodium nitrite.

[0027] If a dosing mechanism 2 is connected to the connecting pipe between the activated carbon filter tank 12 and the security filter 13, the liquid solution poured into the feed hopper 21 can be a phosphonic acid scale inhibitor, a polymer scale inhibitor, or other scale inhibitors.

[0028] In some implementations, please refer to Figure 2 As shown, a rotating shaft 223 is rotatably mounted inside the dosing tank 22, and the receiving pipe 222 is connected to the shaft of the rotating shaft 223. The receiving pipe 222 is oscillatingly mounted inside the dosing tank 22 via the rotating shaft 223.

[0029] It is worth noting that the connection between the medicine receiving tube 222 and the rotating shaft 223 can be fixed together by welding, or by gluing or adhesive bonding.

[0030] In some implementations, please refer to Figure 2 As shown, the dosing mechanism 2 also includes a mixing tank 23; the output pipe 221 of the dosing tank 22 is connected to the inner cavity of the mixing tank 23, and the mixing tank 23 is connected to the filter tank group 1. The mixing tank 23 is connected to the water flow pipeline system of the pure water device, allowing the raw water in the pipeline to enter the inner cavity of the mixing tank 23, which has a space larger than the pipeline. This causes disturbance in the raw water, allowing it to mix better with the hydraulic fluid.

[0031] In some implementations, please refer to Figure 2 As shown, the feed hopper 21 is equipped with a flow regulating valve 211, which is used to control the output flow rate at the discharge end of the feed hopper 21. The flow regulating valve 211 can be used to control the flow rate of the medicine liquid output from the feed hopper 21, thereby controlling the reversing frequency of the medicine receiving pipe 222.

[0032] In some implementations, please refer to Figure 1 As shown, the filter tank assembly 1 includes a media filter tank 11, an activated carbon filter tank 12, and a security filter 13 connected in sequence. A dosing mechanism 2 is connected to the inlet pipe of the media filter tank 11, the connecting pipe between the media filter tank 11 and the activated carbon filter tank 12, and the connecting pipe between the activated carbon filter tank 12 and the security filter 13. During the purification of raw water, the pure water device filters suspended impurities from the raw water through the filter media in the media filter tank 11, reduces the residual chlorine content and filters organic colloids from the raw water through the activated carbon in the activated carbon filter tank 12, and retains or adsorbs trace suspended particles, colloids, and microorganisms in the water through mechanical filtration using the 5μm pores of the PP filter element in the security filter 13.

[0033] It is worth noting that the filter media in the media filter tank 11 can be quartz sand, anthracite, manganese sand, etc., and one or more filter media can be used in combination.

[0034] In some implementations, please refer to Figure 2 As shown, the bottom of the inner cavity of the dosing tank 22 is inclined toward the feed end of the output pipe 221 so that the liquid medicine can flow toward the output pipe 221.

[0035] In some implementations, please refer to Figure 1 As shown, the outlet end of the filter tank group 1 is connected to a reverse osmosis unit 3. The reverse osmosis membrane inside the reverse osmosis unit 3 removes dissolved solids, organic matter, and microorganisms from the raw water.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
