Description

Technical Field

[0001] The utility model relates to a production device for preparing hypochlorous acid sterilizing water with a specified available chlorine concentration and a specified pH value by injecting sodium hypochlorite and dilute hydrochloric acid (or organic acids such as citric acid and acetic acid) into purified water (or tap water) and mixing them through this device. Background Art

[0002] As is well known, hypochlorous acid sterilizing water can be prepared by adding sodium hypochlorite and acidic substances such as dilute hydrochloric acid to purified water (or tap water). However, just like 84 disinfectant and toilet cleaner commonly used in our daily life must never be mixed, in the production process of this hypochlorous acid sterilizing water, due to uneven mixing, not only the stability of the quality of the sterilizing water cannot be guaranteed, but also harmful chlorine gas is very likely to be generated, endangering human health and polluting the environment. Therefore, how to ensure the stability of the quality of the sterilizing water and prevent the generation and overflow of harmful gases is a technical problem that needs to be solved emphatically in the synthesis method for preparing hypochlorous acid sterilizing water. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a production device for hypochlorous acid sterilizing water.

[0004] As Figure 1 shown, the sterilizing water production device is composed of a liquid inlet end, a mixing device, and a liquid outlet end.

[0005] The liquid inlet end is composed of a purified water (or tap water) inlet pipe and one or more injection nozzles installed in front of the end of the inlet pipe. The injection nozzles are respectively connected to an injection pump through injection pipes; the end of the inlet pipe is connected to the liquid inlet of the outer side of the conical mixing device cap of the liquid inlet end through a pipeline joint.

[0006] The mixing device is composed of a conical mixing device cap at the liquid inlet end, a mixing device, and a conical mixing device cap at the liquid outlet end; a liquid inlet is arranged on the outer side of the mixing device cap at the liquid inlet end, a porous shunt partition plate (or mesh) is arranged on the inner side, and a liquid inlet buffer chamber is formed between it and the conical part. The extension part of the conical mixing device cap at the liquid inlet end is sleeved and butted with one end of the mixing device; the inside of the mixing device is filled with corrosion-resistant irregular objects (such as glass balls), and the other end of the mixing device is sleeved and butted with the extension part of the conical mixing device cap at the liquid outlet end; a porous confluence partition plate (or mesh) is arranged on the inner side of the conical mixing device cap at the liquid outlet end, and a liquid outlet buffer chamber is formed between it and the conical part. A liquid outlet is arranged on the outer side of the conical mixing device cap at the liquid outlet end, and the liquid outlet is connected to the liquid outlet pipeline through a pipeline joint.

[0007] The liquid outlet end is composed of a liquid outlet pipeline, which is connected to the liquid outlet on the outer side of the conical mixing device cap at the liquid outlet end through a pipeline joint; the produced sterilizing water is discharged from the liquid outlet pipeline.

[0008] Purified water (or tap water) and liquid medicine enter the conical mixing device cap through the liquid inlet and are first preliminarily mixed in the liquid inlet buffer chamber, and then are shunted into the mixing device through the porous shunt partition plate (or mesh); the mixed liquid entering the mixing device passes through the gaps between the irregular fillers. The gaps not only extend the flow distance of the mixed liquid in the mixing device, but also cause the mixed liquid to form irregular turbulent flows such as shunt, eddy current, and swirl in the mixing device. During this process, the mixed liquid is fully mixed and harmful gases are diluted and dissolved; finally, it converges in the liquid outlet buffer chamber through the porous confluence partition plate (or mesh), is centrally mixed, and is discharged from the liquid outlet pipeline connected to the liquid outlet.

[0009] The beneficial effects of the present utility model are as follows: Structural designs such as a liquid inlet buffer chamber, porous shunt, irregular fillers, porous confluence, and a liquid outlet buffer chamber are adopted. In particular, the irregular fillers in the mixing device not only extend the flow distance of the mixed liquid, but also enable the mixed liquid to form irregular turbulent flows such as confluence, eddy current, and swirl in the mixing device. During this process, the mixed liquid is fully mixed and harmful gases are diluted and dissolved, successfully solving the technical problems of the stability of the quality of disinfected water and preventing the generation and overflow of harmful gases.

[0018] Figure 1 This is the core schematic diagram of the present invention. Purified water (or tap water) enters from the water inlet pipe 1, and the liquid medicine is respectively injected into the water by the injection nozzles 2 and 3 and flows into the mixing device through the liquid inlet 10 of the liquid inlet end conical mixing device cap 9 along with the water flow; after the mixed liquid flows into the liquid inlet end conical mixing device cap 9, it is first preliminarily mixed in the liquid inlet buffer chamber 13 and is shunted into the mixing device 14 through the porous shunt partition plate 12; in the mixing device 14, due to the irregular fillers 15 filled inside, it not only prolongs the flow distance of the mixed liquid in the mixing device 14, but also the mixed liquid will form confluence, eddy current, swirl and other irregular turbulent flows in the mixing device 14, effectively improving the stirring and mixing effect of the mixed liquid and the full dilution and dissolution of harmful gases; then the mixed liquid passes through the porous confluence partition plate 19 of the liquid outlet end conical mixing device cap 16 and converges in the liquid outlet buffer chamber 20 for final confluence and mixing, and is discharged through the liquid outlet pipe 22 connected to the liquid outlet 17 of the liquid outlet end conical mixing device cap 16.

First, after the controller 24 is powered on, the electromagnetic valve driving part 36 drives the electromagnetic valve 29 to open and start water inlet. After there is water inlet, the water inlet amount detection part 31 detects the water inlet amount through the flow sensor 30 and transmits the water inlet amount detection result to the first liquid medicine output amount calculation part 32 and the second liquid medicine output amount calculation part 33. The first liquid medicine output amount calculated by the first liquid medicine output amount calculation part 32 is transmitted to the first liquid medicine injection pump driving part 34 to drive the injection pump 4.
