Apparatus for producing sterilized water

The present invention relates to an apparatus for producing sterilizing water, and in particular, by measuring the amount of tap water supplied from tap water and the like, the amount of alkaline chlorine and acidic chemicals is reduced and the number of times of mixing is increased with respect to the unit tap water supply. The present invention relates to a sterilizing water production apparatus that can obtain safe sterilizing water that is harmless to a human body and has a hydrogen ion concentration close to neutral.

Electrolytic sterilization water is known to vary the form of chlorine in the water depending on the pH, the sterilization power is very different accordingly. Depending on the pH of the electrolytic sterilized water, it is classified into strong acidic electrolyzed water, weakly acidic electrolyzed water, and electrolytic hypochlorite water. Depending on the application field, strong acidic electrolyzed water is applied to agriculture and food fields, and weakly acidic electrolyzed water is applied to medical fields. Sodium water is applied to the living environment and general environment.

Sodium hypochlorite water refers to water containing sodium hypochlorite as an active ingredient, and also includes water obtained by electrolysis of saline. Pale greenish yellow liquid with a chlorine odor. Looking at the generation principle of the electrolytic sodium hypochlorite water, 3% saline solution is electrolyzed in a membrane-free electrolytic cell to produce chlorine at the positive electrode and hydrogen and caustic soda at the negative electrode. The resulting chlorine is dissolved in water and reacts with caustic soda to produce about 1% or less sodium hypochlorite water.

Sterilized with alkaline sterilized water such as sodium hypochlorite to raw water such as tap water. Sterilized water sterilized with alkaline sterilized water has a pH of 10-13, which is strongly alkaline and mixed with hydrochloric acid to make neutral water. It will be used when washing.

It is composed of a control unit 27 for controlling to generate the sterilized water in the range of PH 5 ~ 6.5 by adjusting the amount of alkali chemicals and acidic chemicals supplied to the mixing device 22.

Referring to FIG. 3, tap water is introduced through a hose connected from the tap water supply unit 11, and the introduced tap water is supplied to the water shutoff valve 12 when the operation of the sterilizing water production apparatus of the present invention is stopped. Inflow is blocked.

When the user presses the movable switch 27a provided in the control device 27, the control device 27 controls the water supply shutoff valve 12 to be opened so that the tap water flows through the hose 11a.

4 is a cross-sectional structural diagram showing the structure of the metering pump according to the present invention.

The first and second metering pumps 18 and 19 according to the present invention shorten the length of the cylinder 34a in which the piston 35 provided in the pump reciprocates, and per minute according to the fluctuation of the tap water flow rate. The number of injections of the aqueous chemical solution was increased up to 720 times to optimize the injection of 38ml / 720 당 0.053ml per stroke.

 The first and second metering pumps 18 and 19 according to the present invention have a maximum output of 720 rpm, and when the flow rate of tap water flowing into the mixing device 22 is 10 l / min to 12 l / min, The pump divides each chemical solution into 30 ml ~ 38 ml per minute 720 times and sprays 38 ml / 720 ≒ 0.053 ml per time to the mixing device 22, and the remaining tap water and the chemical aqueous solution are mixed at a predetermined ratio. Chlorine concentration 20ppm, pH 5 ~ 6.5 optimum sterilization water can be produced stably.

The first and second metering pumps 18 and 19 according to the present invention shown in FIG. 4 are connected to the first and second chemical tanks 40a and 40b by chemical suction hoses to suck the chemicals and prevent backflow. Section 36; A piston (35) for suction movement so that the medicine is sucked from the suction portion (36) and a discharge movement for discharge of the sucked medicine to the discharge portion (37); A cylinder body 34 which provides a space for the piston 35 to reciprocate between suction and discharge; A blocking film (35a) installed inside the cylinder (34a) to prevent the medicine sucked by the suction movement of the piston (35) into the cylinder (34a); Each of the discharge parts 37 for supplying the mixing device 22 to prevent the backflow of the medicine discharged by the discharge movement of the piston 35, respectively.

The suction unit 36 is a suction port 36a connected to the chemical tank 40 by a chemical suction hose; The suction check ball 38a which is separated from the suction port 36a at the time of suction, opens the suction port 36a, and blocks the suction port 36a at the time of discharge and prevents backflow, and expands at the time of suction, and the suction check ball 38a. A suction check valve (38) composed of a check spring (38b) which causes the suction check ball (38a) to block the suction port (36a) so as to be separated from the suction port (36a) and to contract upon discharge; It consists of a suction pipe (34b) for sucking the medicine sucked during the suction movement of the piston 35 in the space between the blocking film 35a and the right end of the cylinder (34a).

Similarly, the discharge part 37 includes: a discharge pipe 34c for discharging the medicine in the space between the blocking film 35a and the right end of the cylinder 34a during the discharge movement of the piston 35; The discharge check ball 39a which blocks the discharge pipe 34c at the time of inhalation and opens the discharge pipe 34c at the time of discharge and prevents backflow, and contracts upon suction so that the discharge check ball 39a is discharged to the discharge pipe 34c. A discharge check valve (39) composed of a check spring (39b) which prevents the opening and expands upon discharge to allow the discharge check ball (39a) to open the discharge pipe (34c); It is composed of a discharge port (37a) for supplying the drug discharged from the discharge check valve 39 to the mixing device (22).

Therefore, the check valve of the conventional metering pump shown in FIG. 5 configures two check balls in the discharge pipe and the suction pipe to solve the problem that the two check balls are not attached to the discharge pipe and the suction pipe when operating at a high speed of 720spm. .

The first and second chemical tanks (40a, 40b) is provided with a water level detection sensor 20, respectively, to detect the remaining amount of the stored aqueous solution, and when the storage amount of the aqueous solution is less than the input reference value to send a signal to the control device (27) The operation of the first and second metering pumps 18, 19 is immediately stopped.

The first and second metering pumps 18 and 19 according to the present invention shorten the length of the cylinder 34a in which the piston 35 provided in the pump reciprocates, and thus chemicals per minute due to fluctuations in the tap water flow rate. It is optimized to spray 38 ml / 720 × 0.053 ml per time by dividing 720 times only the amount of aqueous solution (30 ml to 38 ml) in real time.

The first and second metering pumps 18 and 19 according to the present invention have a maximum output of 720spm and when the flow rate of tap water flowing into the mixing device 22 is 10 l / min to 12 l / min, The first and second metering pumps 18 and 19 immediately spray each chemical solution into the mixing device 22 by a maximum of 720 strokes, 30 ml to 38 ml per minute.

Thus, 13.8 ml to 16.6 ml of tap water per stroke is mixed with 0.042 to 0.053 ml of sodium hypochlorite solution at a constant ratio, and neutralized by mixing o.042 to 0.053 ml of aqueous hydrochloric acid solution to give a residual chlorine concentration of 20 ppm and a pH of 5 to 6.5. The optimal sterilization water can be produced stably.

Figure 7 (a) shows a process of mixing the drug in the mixing device by a conventional metering pump.

According to FIG. 7 (a), the conventional metering pump having a maximum output of 360spm is impossible to inject into the fine particles when injecting the aqueous chemical solution into the mixing device due to the limitation of the pump output, so that the chemical aqueous solution and flowing tap water Mixing reactions occur unevenly.

For example, the portion of the sodium hypotitanium chemical solution injected into the running tap water by the conventional first metering pump has a high chlorine concentration of 30 to 50 ppm, for example, and a little time after the chemical is added (for example, In the tap water flowing after 1 second), the chlorine concentration is almost 0ppm, so the residual chlorine concentration is not constant.

In addition, even when the hydrochloric acid aqueous solution was added to the second metering pump to neutralize the tap water which became alkaline due to the addition of the aqueous sodium hyponitrate chemical solution by the first metering pump, only the portion into which the hydrochloric acid aqueous solution was added was neutralized. Although the pH is 5 to 6.5, the tap water flowing after a certain time (for example, 1 second) is not neutralized and has an alkalinity of pH 7 to 8, which limits the production of optimal sterilized water.

7 (b) shows a process of mixing the drug in the mixing device by the metering pump according to the present invention.

The first and second metering pumps 18 and 19 having a maximum output of 720spm according to the present invention are capable of spraying a chemical solution into fine particles (38 ml / 720 ≒ 0.0053 ml) and the flow rate of tap water is 10 to 12 l per minute. In the case of, the first and second metering pumps (18, 19) are sprayed and mixed at a rate of 30 to 38 ml of the aqueous chemical solution at a speed of 720 strokes per minute to stably obtain an optimal sterilizing water having a pH of 5 to 6.5. It becomes possible.

6 shows another embodiment of the metering pump according to the present invention.

In the metering pump according to the present embodiment, a stroke adjusting knob 341 is additionally installed in the cylinder body 34 of the metering pump of the present invention shown in FIG. 4, and the speed reducer is configured to move the stroke adjusting knob 341 forward and backward. A motor 343 for providing rotational power to the 342 and the reducer 342 is further installed.

The motor 343 is controlled by the control device 27 to perform the forward and reverse rotation, the forward and reverse rotation of the motor 343 is decelerated by the reducer 342, the stroke adjustment knob 341 By passing the stroke adjusting knob 341 forward and backward, the metering pump can be operated at a maximum 720spm while controlling the amount of chemical solution injected per stroke.

Therefore, according to this embodiment, even if the amount of tap water supplied from the tap water supply unit 11 is changed, the sodium hypochlorite aqueous solution and Aqueous solution of hydrochloric acid is added at the desired concentration (for example, 20 ppm), and the number of injections is up to 720 times per minute. You will get
