Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of secondary water supply, in particular to a sodium hypochlorite disinfectant supplement device, which can realize rapid supplement of sodium hypochlorite disinfectant and shorten the time for mixing evenly. BACKGROUND

[0002] At present, the disinfection of urban domestic drinking water (commonly known as tap water) in China is mostly by sodium hypochlorite disinfectant. After adding sodium hypochlorite disinfectant to tap water, a sufficient residual chlorine concentration can be maintained in the tap water pipe network system for a long time, so as to ensure that the microorganisms in the tap water are controlled within the qualified range. Residual chlorine refers to the amount of chlorine remaining in the water after a certain time of chlorine addition and contact during disinfection by sodium hypochlorite disinfectant. However, in order to avoid water shortage for users, the water supply system often reserves a large amount of water in the water tank, which leads to the need for tap water to stay in the water tank. If the residence time of tap water in the water tank is too long, such as more than 12 hours, the residual chlorine concentration in the tap water will decay to a low level, which not only fails to effectively kill the microorganisms in the water, but also causes the microbial indicators of tap water in the water tank to exceed the standard.

[0003] In order to solve the technical problem of residual chlorine concentration decay caused by long residence time of tap water in the water tank, the applicant applied for a patent technology of a secondary water supply intelligent chlorine supplement disinfection system and a method for supplementing chlorine (publication number CN111233112A) in 2020. This technology can generate a certain amount of sodium hypochlorite disinfectant stock solution from a sodium hypochlorite generator when the residual chlorine concentration of tap water in the water tank is detected to be lower than the set value, then dilute the sodium hypochlorite disinfectant stock solution in the first dilution tank and the second dilution tank in turn, and finally add the diluted usable disinfectant to the water tank through the dosing assembly.

[0004] At present, this technology has been actually produced and tested in many areas. After diluting the sodium hypochlorite disinfectant stock solution into usable disinfectant, the water pump directly supplements the usable disinfectant into the water tank to ensure that the residual chlorine concentration of tap water meets the standard. However, in actual application, the applicant found that after the usable disinfectant is supplemented into the water tank, it is difficult to quickly spread due to the unsuitability of large-scale stirring in the water tank, so there are still technical problems of slow supplement speed, poor timeliness, and slow mixing of usable disinfectant after supplement, which still have a great impact on the safety of water use of users. SUMMARY

[0005] The purpose of the present application is to provide a sodium hypochlorite disinfectant supplement device, which can further improve the supplement speed of usable disinfectant and accelerate the mixing speed of usable disinfectant in tap water, thereby maximizing the safety of water use of users.

[0006] To achieve the above object, the technical scheme adopted by the present application is as follows:

[0007] A sodium hypochlorite disinfectant supplement device is characterized by comprising a box body, a controller, a sodium hypochlorite generator, a dilution tank, a compressed air blower, a liquid delivery assembly, a gas delivery assembly, and a rotating output assembly fixed in a water tank.

[0008] The rotating output assembly comprises an output main pipe, output branch pipes, a plurality of temporary storage containers, and a plurality of rotating spray heads.

[0009] The controller, the sodium hypochlorite generator, the dilution tank, and the compressed air blower are all fixed in the box body.

[0010] When the residual chlorine concentration of the tap water in the water tank is lower than the set value, the controller first controls the sodium hypochlorite generator to produce a disinfectant stock solution and dilute it into usable disinfectant in the dilution tank.

[0011] The temporary storage containers are spherical in structure and have a plurality of circular through holes.

[0012] The number of temporary storage containers is 4-6, and the temporary storage containers are arranged in a rectangular shape in the same orthographic projection plane.

[0013] The temporary storage containers have different heights in the water tank.

[0014] The rotating spray heads have a plurality of rotating water spray parts.

[0015] The compressed air blower is installed at the bottom of the box body, the sodium hypochlorite generator is fixed above the compressed air blower through a partition, and the controller is fixed at the upper part of the box body.

[0016] An air filter is fixed on the side of the box body and connected to the air inlet end of the compressed air blower.

[0017] The infusion assembly comprises an infusion tube and an infusion pump mounted on the infusion tube, and the gas infusion assembly comprises a gas infusion tube and a solenoid valve mounted on the gas infusion tube, and the infusion pump and the solenoid valve are connected with the controller.

[0018] The infusion tube between the dilution tank and the rotating output assembly has the same pipe diameter as the output main pipe, and the pipe diameter of the infusion tube and the output main pipe is multiple times of the pipe diameter of the output branch pipe.

[0019] The advantages of the present application are as follows:

[0020] 1. The present application has two key improvements compared with the prior art, as follows:

[0021] One of the improvements is to provide a rotating output assembly comprising a plurality of temporary storage containers and a plurality of rotating nozzles, which has the advantage of being able to supplement the available disinfectant in the temporary storage container into tap water in a rotating manner. Specifically, during the supplementing process, the rotating action of the rotating nozzles can play a small-scale stirring role, and the number of rotating nozzles is multiple, so that the combination of the two can accelerate the diffusion speed of the available disinfectant, so that the available disinfectant can be mixed uniformly faster, thereby improving the timeliness of the available disinfectant supplement.

[0022] The second improvement is to provide a compressed air blower and a gas infusion assembly connecting the compressed air blower and the rotating output assembly, which has the advantage that after the available disinfectant in the dilution tank is completely delivered into the temporary storage container, the remaining available disinfectant in the temporary storage container can be automatically supplemented into the tap water through the rotating nozzles under the extrusion action of air pressure. On the one hand, under the extrusion of air pressure, the remaining available disinfectant can be supplemented into the tap water in a rotating stirring manner as in the first improvement, and the outflow speed of the available disinfectant can be increased by increasing the pressure, i.e. the available disinfectant can be rapidly supplemented into the tap water, thereby further improving the supplementing speed and shortening the supplementing time. On the other hand, as the supplementing process proceeds, when the available disinfectant in the temporary storage container is completely supplemented into the tap water, the compressed air blower can continue to pressurize to facilitate bubbling of the tap water, thereby further accelerating the diffusion speed of the available disinfectant.

[0023] In summary, the present application has the advantages of fast supplementing speed, high timeliness, and fast mixing of the available disinfectant, thereby effectively improving the water safety of users.

[0024] 2. The present application sets the temporary storage container as a spherical structure, and a plurality of circular through holes are formed on the temporary storage container. The circular through holes can serve as the outflow port of the available disinfectant on the temporary storage container, thereby accelerating the supplementing speed of the available disinfectant, and the plurality of circular through holes can also simultaneously bubble under the action of subsequent air pressure, thereby further improving the mixing speed of the available disinfectant.

[0025] 3、The number of temporary storage containers is set to 4-6, and the temporary storage containers are arranged in a rectangular shape in the same orthographic projection plane. The advantage is that multiple areas can be supplemented and mixed at the same time, so that the supplementing effect of the available disinfectant is better.

[0026] 4、The height of the temporary storage container in the water tank is set to be different, which further improves the supplementing effect of the available disinfectant.

[0027] 5、The air filter can filter various impurities in the air for the compression fan, so that the impurities in the air do not enter the tap water and affect the water quality safety.

[0028] 6、The infusion tube and the infusion pump are used as the infusion assembly, and the gas conveying pipe and the electromagnetic valve are used as the gas conveying assembly, which has the advantages of simple structure, easy control and good conveying effect.

[0029] 7、The pipe diameter of the infusion tube and the output main pipe between the dilution tank and the rotary output assembly is set to be the same, and the pipe diameter of the infusion tube and the output main pipe is set to be multiple times larger than the pipe diameter of the output branch pipe, which has the advantages that the available disinfectant in the dilution tank can be quickly conveyed to multiple temporary storage containers, and the conveying speed and supplementing speed of the available disinfectant in the dilution tank are further improved.

DETAILED DESCRIPTION

[0033] Example 1

[0034] The present application provides a sodium hypochlorite disinfectant supplementing device, which is a further improvement based on the patent technology with publication number CN111233112A. The improved supplementing device can realize rapid supplementing and rapid mixing of the available disinfectant. Figure 1As shown, it comprises a box body 1, a controller 2, a sodium hypochlorite generator 3, a dilution tank 4, a compressed air fan 5, a liquid delivery assembly 6, a gas delivery assembly 7 and a rotating output assembly 8 for fixing in a water tank 19. Wherein, the structure, position and connection relationship of each component are as follows respectively:

[0035] The box body 1 is a cuboid structure, which has an internal space for installing the controller 2, the sodium hypochlorite generator 3, the dilution tank 4 and the compressed air fan 5.

[0036] The controller 2, the sodium hypochlorite generator 3 and the dilution tank 4 are all conventional structures, and the specific structure, function and the like are referred to the patent document with the publication number CN111233112A, which will not be repeated here.

[0037] The liquid delivery assembly 6 comprises a liquid delivery pipe 15 and a liquid pump 16 installed on the liquid delivery pipe 15, and the gas delivery assembly 7 comprises a gas delivery pipe 17 and an electromagnetic valve 18 installed on the gas delivery pipe 17, and the liquid pump 16 and the electromagnetic valve 18 are both connected with the controller 2.

[0038] The controller 2, the sodium hypochlorite generator 3, the dilution tank 4 and the compressed air fan 5 are all fixed in the box body 1, wherein the compressed air fan 5 is installed at the bottom of the box body 1, the sodium hypochlorite generator 3 is fixed above the compressed air fan 5 through a partition plate 14, and the controller 2 is fixed at the upper part of the box body 1. The electrolytic cell of the sodium hypochlorite generator 3 is connected with the dilution tank 4 through the liquid delivery assembly 6, the dilution tank 4 is connected with an output main pipe 9 through the liquid delivery assembly 6, the compressed air fan 5 is connected with the output main pipe 9 through the gas delivery assembly 7, and the controller 2 is connected with the sodium hypochlorite generator 3, the compressed air fan 5, the liquid delivery assembly 6 and the gas delivery assembly 7 respectively. The controller 2 can control the sodium hypochlorite generator 3 to produce sodium hypochlorite disinfectant stock solution quantitatively, control the liquid pump 16 to deliver the sodium hypochlorite disinfectant stock solution to the dilution tank 4 for dilution, control the liquid pump 16 to deliver the diluted available disinfectant in the dilution tank 4 to the rotating output assembly 8 for replenishment, and control the compressed air fan 5 and the electromagnetic valve 18 to input compressed air into the rotating output assembly 8.

[0039] The rotating output assembly 8 comprises an output main pipe 9, a plurality of output branch pipes 10, a plurality of temporary storage containers 11 and a plurality of rotating spray heads 12, as shown in Figure 2 Each rotating spray head 12 has a plurality of rotating water spraying parts, the output main pipe 9 can be bolted at the top of the water tank 19, the plurality of temporary storage containers 11 are respectively installed below the tap water surface in the water tank 19 through the output branch pipes 10, and the plurality of rotating spray heads 12 are respectively installed at the lower part of the plurality of temporary storage containers 11. In order to facilitate installation and disassembly, thread connection is preferably adopted between the temporary storage container 11 and the output branch pipe 10 and between the temporary storage container 11 and the rotating spray head 12.

[0040] Further preferably, the infusion pipe 15 between the dilution tank 4 and the rotating output assembly 8 has the same pipe diameter as the output main pipe 9, and the pipe diameter of the infusion pipe 15 and the output main pipe 9 is multiple times of the pipe diameter of the output branch pipe 10. It should be noted that the multiple times of the pipe diameter of the infusion pipe 15 and the output main pipe 9 relative to the pipe diameter of the output branch pipe 10 can be determined according to the number of the temporary storage containers 11. For example, if the number of the temporary storage containers 11 is 4, the pipe diameter of the infusion pipe 15 and the output main pipe 9 is 4 times of the pipe diameter of the output branch pipe 10. In this way, the available disinfectant in the dilution tank 4 can be quickly delivered to the multiple temporary storage containers 11, so as to improve the replenishment speed of the available disinfectant.

[0041] When the residual chlorine detector in the water tank 19 detects that the residual chlorine concentration in the tap water is lower than the set value, the controller 2 controls the sodium hypochlorite generator 3 to produce a certain amount of sodium hypochlorite disinfectant stock solution, and then the sodium hypochlorite disinfectant stock solution is delivered to the dilution tank 4 through the infusion assembly 6 for dilution. The sodium hypochlorite disinfectant stock solution is diluted into available disinfectant in the dilution tank 4, and then the available disinfectant is simultaneously delivered to the multiple temporary storage containers 11 through the infusion assembly 6. During the delivery process, the available disinfectant entering the temporary storage containers 11 first is automatically replenished into the tap water under the action of pressure through the rotating spray head 12. With the replenishment of the available disinfectant, the spraying and rotating actions of the rotating spray head 12 can play a small amount of stirring action, so as to further accelerate the diffusion speed and mixing speed of the available disinfectant.

[0042] When the delivery of the available disinfectant in the dilution tank 4 is completed, the controller 2 controls the infusion assembly 6 to stop working, controls the gas infusion assembly 7 to open, and controls the compressed air blower 5 to input compressed gas into the temporary storage containers 11 through the gas infusion pipe 17. Under the extrusion action of the compressed gas, the remaining available disinfectant in the temporary storage containers 11 is automatically replenished into the tap water through the rotating spray head 12. During the input of the compressed gas, the compressed gas not only extrudes the available disinfectant into the tap water, but also generates a bubbling action in the tap water through the rotating spray head 12 and the circular through hole 13, so as to further accelerate the diffusion speed and mixing speed of the available disinfectant.

[0043] In summary, the replenishment time of the available disinfectant can be shortened by 10%-26% and the time for the available disinfectant to be mixed uniformly in the tap water can be shortened by 8%-15% after the specific technical scheme is adopted in the present application. Therefore, the present application has high innovation.

The temporary storage containers 11 are spherical structure, and a plurality of circular through holes 13 are formed on the temporary storage containers 11.

[0046] It is to be noted that the size and number of the temporary storage containers 11 are related to the size of the dilution tank 4, and the specific size and number are preferably that the dilution liquid in the dilution tank 4 can be delivered to each temporary storage container 11 at one time. In addition, in order to improve the replenishment effect of the available disinfectant, the height of the temporary storage containers 11 in the water tank 19 is preferably different, but the temporary storage containers 11 are arranged in a rectangular shape in the same orthographic projection plane from top to bottom.

[0047] The embodiment can simultaneously replenish the available disinfectant in multiple regions in actual implementation, so as to reduce the diffusion distance of the available disinfectant, thereby realizing rapid mixing of the available disinfectant.
