Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Fig. 1 is an exemplary simplified diagram illustrating an apparatus 100 for automatically proportioning sanitizing liquid in a mixing tank according to the present invention. As shown in fig. 1. The apparatus 100 may comprise a first level gauge 101, a pH detector 102, and a controller 103. The aforementioned first level gauge 101, the ph value detector 102, and the controller 103 will be described in detail below, respectively.

In one embodiment, the above-mentioned first level gauge 101 may be arranged within the mixing tank and used for measuring first level height information in the mixing tank. In some implementation scenarios, the first level gauge may be, for example, a drop-in level gauge. The input type liquid level meter can be composed of a special gas guide cable with a built-in capillary hose, a pressure-resistant joint and a probe, wherein the probe comprises a pressure sensor. In operation, a drop-in level gauge detects the static pressure at the bottom of a liquid with its probe based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. Further, the pressure sensor may convert the aforementioned measured static pressure signal into an electrical signal to notify the controller.

Specifically, the utility model can measure the current liquid level height of the disinfection solution in the mixing tank by using the input type liquid level meter, and converts the detected current liquid level height of the disinfection solution in the mixing tank into an electric signal through the pressure sensor of the liquid level height, so that the information of the current liquid level height of the disinfection solution in the mixing tank is transmitted to the controller. Furthermore, the height of the clear water level participating in the proportioning of the disinfectant in the mixing tank can be obtained by utilizing the input liquid level meter. Similar to the above, the level of the clear water can be further converted into an electrical signal form to be transmitted to the controller.

In one embodiment, the ph detector 102 may be disposed in the mixing tank and configured to detect the ph of the disinfectant to obtain ph information of the disinfectant. In one exemplary scenario, the PH detector may be, for example, a PH meter, which may be placed within the sterile solution in the mixing tank. In operation, the PH value of the disinfectant in the mixing tank is measured by the PH meter, so that the pH value information of the disinfectant in the mixing tank can be obtained. Similar to the principle of operation of a liquid level meter, a PH meter may be utilized to convert the detected PH information into an electrical signal and transmit the electrical signal to a controller.

In one embodiment, the controller 103 may be communicatively connected to the first liquid level meter and the ph detector, and may be configured to receive detection results of the first liquid level meter and the ph detector. Further, the controller can control the mixing tank to be automatically filled with a preset amount of clear water and mother liquid according to the detection result so as to obtain the expected proportioning of the disinfectant. In one application scenario, as mentioned above, the detection result here may be an electrical signal and specifically may be a first electrical signal that is generated by converting the detected liquid level height of the disinfection liquid in the mixing tank via the first liquid level meter, or may be a second electrical signal that is generated by converting the detected liquid level height of the clean water that participates in the proportioning of the disinfection liquid in the mixing tank via the first liquid level meter. In addition, the electric signal can also be a third electric signal generated by converting the pH value information of the disinfectant in the mixing tank detected by the pH value detector. Thereafter, the controller can compare the received electric signal value with a preset value, and determine to automatically fill the mixing tank with a preset amount of clear water and mother liquid according to the comparison result of the detected electric signal value and the preset value so as to obtain the expected ratio of the disinfectant.

Specifically, the controller may be configured to determine that the liquid level of the disinfecting liquid in the mixing tank is lower than a predetermined level when the first electrical signal value is lower than a first predetermined value, and further determine that a predetermined amount of clean water needs to be filled into the mixing tank. Further, the controller may be configured to determine a predetermined amount of fresh water filled into the mixing tank when the second electrical signal reaches a second predetermined value, and then control to open the fresh water filling switch on the mixing tank to fill the predetermined amount of fresh water into the mixing tank. The controller can also be used for determining that the pH value of the disinfectant in the mixing tank does not reach the preset pH value when the third electric signal does not reach the third preset value and/or the preset value range, so as to determine the amount of the mother liquor to be filled into the mixing tank according to the pH value detector.

With the above description, the present invention can obtain the first liquid level height information in the mixing tank through the first liquid level meter, where the first liquid level height includes the liquid level height of the current disinfectant in the mixing tank and/or the clear water liquid level height participating in the proportioning of the disinfectant in the mixing tank. Further, the pH value of the disinfectant in the mixing tank can be detected by the pH value detector so as to obtain the pH value information of the disinfectant. In operation, the first liquid level height information and the pH value information received by the controller determine that the mixing tank is automatically filled with the predetermined amount of clear water and mother liquid to obtain the expected ratio of the disinfectant.

Fig. 2 is an exemplary simplified block diagram illustrating a system for automatically proportioning sanitizing liquids in a mixing tank in accordance with the present invention. As shown in fig. 2, the system may further include a mother liquor tank 201 and a peristaltic pump 202, in addition to the first liquid level meter 101, the ph value detector 102 and the controller 103 (i.e., the device for automatic proportioning of the present invention) shown in fig. 1. It will be appreciated that the first level gauge 101 and the ph indicator gauge 102 have been described in detail above with reference to fig. 1, and therefore the same will not be described in detail below.

In one embodiment, a mother liquor filling port for filling mother liquor and a clean water filling switch are arranged on the mixing tank, and the mother liquor filling port is connected with the above-mentioned peristaltic pump 201 for conveying mother liquor to the mother liquor filling port. In the case of a peristaltic pump, a constant rate of flow of liquid is obtained by pumping the liquid to the outside by alternately squeezing and releasing the flexible delivery hose of the peristaltic pump with rollers of a constant rate. Based on the operating principle of the peristaltic pump, the liquid amount flowing through the peristaltic pump in the working time can be calculated according to the working time of the rollers of the peristaltic pump and a related formula. In one embodiment, the foregoing formula may have the following expression:

T＝total_water/ratio/(per_flow/1000) (1)

where T represents the time for turning on the peristaltic pump (i.e., its working time) in seconds; total _ water represents the amount of fresh water added to the mix tank in liters ("L"); ratio represents the proportioning coefficient of the mother liquor and the clear water in the mixing tank, and the proportioning coefficient is 1:100 in the formula (1); per flow represents the flow rate of the peristaltic pump Per second in ml/sec.

In an exemplary operating scenario, the above peristaltic pump may deliver a predetermined amount of mother liquor to the mother liquor inlet at a constant rate, and the predetermined amount of mother liquor may be filled to the mother liquor inlet as determined by the length of time the peristaltic pump is operated. Therefore, the peristaltic pump is adopted in the operation, the mother liquor in the mixing tank in the proportioning with the disinfectant can reach the preset proportioning value, so that the precise proportioning of the disinfectant in the mixing tank is ensured, meanwhile, the equipment can be ensured to avoid excessive disinfectant waste (namely the mother liquor), and the proportioning effect of the disinfectant proportioning scheme is further optimized.

In one embodiment, the controller 103 is communicatively connected to the peristaltic pump 201 for determining an operation time period of the peristaltic pump according to the amount of fresh water filled in the mixing tank, the desired ratio and the flow rate of the peristaltic pump and controlling the operation of the peristaltic pump for the predetermined amount of mother liquid filled in the mixing tank. Specifically, the controller can determine to output a time length signal of required work to the peristaltic pump according to a second electric signal (namely, the liquid level height information of the clean water participating in the proportioning of the disinfectant in the mixing tank) input by the first liquid level meter, so as to fill the mother liquid related to the proportionality coefficient into the mixing tank. In one embodiment, a mother liquor tank 202 holding mother liquor is connected to the peristaltic pump described above and may be used to match the mother liquor that is poured into the mixing tank via the peristaltic pump. In some application scenes, the agent for matching the mother liquor can be a powder disinfectant, the mother liquor tank is used for mixing the powder disinfectant with clear water in the mother liquor tank at high concentration, the powder disinfectant can be uniformly mixed with the clear water, and the phenomenon that the powder agent does not fully exert the disinfection effect can be avoided.

In one embodiment, a feed valve may be disposed on the mother liquor tank and used to control the entry of fresh water into the mother liquor tank. Furthermore, a Hall flowmeter used for detecting the flow of the clear water filled into the mother liquor tank is arranged at a water inlet valve of the mother liquor tank, and a pulse signal generated by the change of the rotating speed of the magnetic rotor caused by the change of the water flow is output to the controller through the Hall flowmeter, so that a preset amount of clear water is added into the mother liquor tank according to a proportioning coefficient. In addition, a second liquid level meter is arranged on the mother liquor tank and used for measuring the height of a second liquid level in the mother liquor tank and converting the height information of the second liquid level into an electric signal according to the principle so as to input the signal to the controller. In one application scenario, the second liquid level meter may be, for example, a duckbill liquid level meter, which uses a floating ball to trigger the magnetic reed switch to be closed or opened according to the up-and-down movement of the liquid to generate a switch signal, and transmits the switch signal to the controller, so that the liquid level height of the mother liquid in the mother liquid tank can be determined by triggering the magnetic reed switch to be closed or opened.

To enable control of the mother liquor tank 202, the controller 103 of the present invention may also be communicatively coupled to the mother liquor tank 202, such as to a water inlet valve, a hall flow meter, and a second level meter disposed on the mother liquor tank, to enable control of the mother liquor tank. For example, the controller may control to open the water inlet valve according to the second liquid level information measured by the second liquid level meter so as to fill a predetermined amount of clean water into the mother liquid tank. Furthermore, the controller can detect the flow of clear water filled into the mother liquor tank by controlling a Hall flowmeter arranged at the water inlet valve, so that the control of the amount of the clear water filled into the mother liquor tank is realized.

Fig. 3 is another exemplary block diagram illustrating a system for automatically proportioning sanitizing liquids in a mixing tank in accordance with the present disclosure. As can be seen from what is shown in fig. 3, the system comprises the first liquid level meter 101, the ph value detector 102, the controller 103, the mother liquor tank 201 and the peristaltic pump 202 shown in fig. 2, which are described above, and additionally comprises a user interface 301 and an alarm unit 302. Since the first level gauge 101, the ph value detecting gauge 102, the controller 103, the mother liquor tank 201, and the peristaltic pump 202 have been described in detail with reference to fig. 1 and 2, the same contents will not be described in detail below.

In one embodiment, the alarm unit 302 may be connected to an output of the controller 103, and configured to control the alarm module to indicate to a user that a medicament and a predetermined amount of fresh water are required to be added to the mother liquor when a second liquid level measured by a second liquid level meter in the mother liquor tank is lower than a predetermined value. When the staff hear the alarm unit and report to the police, it can for example in time add the filling agent or investigate various trouble, reduces inspection cost and administrative cost from this.

In one embodiment, the user interface 301 may be connected to an input of the controller 103 and configured to receive the solvent information and the ratio parameter input by the user, and the controller controls the addition of the medicament of the disinfecting liquid and the predetermined amount of the clear water to the mother liquid tank based on the solvent information and the ratio parameter. The user interface is connected with various display screens (or called screens), and the user can set the solvent information and the proportion parameters to be proportioned on the display screens so as to realize the expected accurate proportioning in the mixing tank. In one scenario, the aforementioned display screen may be a touch-sensitive display screen on which various image elements or components may be arranged for receiving the aforementioned various parameters or instructions input by a user through touch, including, but not limited to, for example, a dose amount, a formula ratio, a working time of a peristaltic pump, and the like. It can be seen that by providing a user interface connected to the controller, the device of the present invention is also more user friendly, thereby also significantly improving the user experience.

Fig. 4 is an exemplary schematic detail view showing a system for automatically proportioning sterilizing fluids according to the present invention. It is to be understood that the system shown in fig. 4 may be a specific implementation of the systems shown in fig. 2 and 3, and therefore the description made above in conjunction with fig. 2 and 3 is also applicable to the situation shown in fig. 4 and the same contents will not be described again.

As shown in fig. 4, the system has a display 401 arranged at the user interface and on which medicament and proportioning parameters are provided for the user to select the proportioning. Additionally or alternatively, various input boxes may be provided on the user interface of the display screen for the user to input specific proportioning parameters. In one scenario, the second liquid level in the mother liquor tank can be measured according to a second liquid level meter 408 arranged on the mother liquor tank, and when the second liquid level is lower than a preset value, the controller 103 is used for controlling the alarm unit to output an alarm signal, so that a worker is reminded to add a disinfectant participating in mother liquor proportioning into the mother liquor tank. Further, the controller 103 may be utilized to open the inlet valve 402 on the mother liquor tank 202 according to the parameters set by the display 401, thereby allowing a certain amount of clean water to enter the mother liquor tank 202. In operation, data on the amount of incoming water may be acquired by a hall flow meter 403 arranged at the inlet valve 402, whereby the inlet valve 402 is controlled by the controller 103 to close after a predetermined fresh water inlet amount is reached in the mother liquor tank. Thereafter, in order to achieve sufficient mixing, the controller may control to turn on the first stirrer 404 disposed on the mother liquor tank 202 to perform a stirring operation for a certain period of time.

According to the above description, after the first mixer 404 finishes mixing, the controller may control to open the clean water filling switch 405 on the mixing tank, and fill a certain amount of clean water into the mixing tank. When the liquid level of the clear water reaches the required height, the first liquid level meter 101 for detecting the first liquid level sends a signal to the controller 103, the controller is used for controlling the peristaltic pump 201 connected with the mother liquid filling port on the mixing tank to open the switch, and a certain amount of mother liquid is pumped into the mixing tank through the peristaltic pump 201.

Further, the ph value of the disinfectant is detected by the ph value detector 102 disposed in the mixing tank, and the controller 103 can control the peristaltic pump 201 to continuously fill the mother liquor into the mixing tank by using the ph value information until the ph value of the disinfectant in the mixing tank reaches a predetermined effect. Additionally, the controller 103 may agitate the sanitizing liquid in the mixing tank to a predetermined effect using a second agitator 406 disposed on the mixing tank. After appropriate stirring, the controller 103 controls the medicine outlet valve 407 on the mixing tank to open, so as to provide the disinfectant in the mixing tank to the outside for disinfection, thereby realizing normal operation and use of the whole system. In order to ensure safe and efficient operation, various components in the system can be monitored in real time in the operation process of the system, and the state information of the relevant components can be uploaded to the cloud end through a wireless module (for example, based on a 4G or 5G cellular communication technology or a wireless local area network technology). Therefore, the utility model can realize remote monitoring and control of the device for automatic proportioning and the system thereof. For example, when the system fails, the system can automatically push the fault information to the staff in a wireless manner, so that the staff can know the equipment state in real time and perform troubleshooting in time. Therefore, the use of the system also substantially reduces inspection costs and administrative costs.

To facilitate understanding of aspects of the embodiments described herein, fig. 5 is an exemplary flow chart illustrating an automatic proportioning for sterilizing fluid in a mixing tank according to the present invention.

As shown in fig. 5, first, the entire system (such as the systems shown in fig. 2, 3, and 4) is started in step 501. Next, in step 502, it is determined whether the system operating state is normal. If an abnormal condition of the system is detected, then a fault message is pushed to system maintenance personnel in step 503. Thereafter, in step 504, system maintenance personnel can stop operation of the system or related malfunctioning component (e.g., flow meter or peristaltic pump herein). Thereafter, system maintenance personnel can inspect and troubleshoot the fault. After troubleshooting, the flow may return to step 502 (not shown for purposes of simplicity and clarity) and proceed to step 505 after the detected system is operating properly.

In step 505, it is determined whether the liquid level condition in the mother liquor tank is a low liquid level. If the liquid level is below the predetermined normal level, then proceed to step 506 for alert message push to alert the addition of medicament to the mother liquor tank. Thereafter, the flow returns to step 505 to continue determining the liquid level condition in the mother liquid tank. As described above, in order to achieve that the liquid level state can be maintained at a normal state or a normal value, in the present invention, the controller controls the second liquid level gauge disposed on the mother liquid tank to monitor the liquid level height of the mother liquid in the mother liquid tank, and controls the alarm unit according to the liquid level height of the mother liquid in the mother liquid tank. When the liquid level height of the mother liquor in the mother liquor tank is a low liquid level, the controller controls the alarm unit to remind a worker to add the medicament into the mother liquor tank, and controls the Hall flowmeter arranged on the mother liquor tank to add a certain amount of clear water into the mother liquor tank according to the proportional parameters, so that the liquid level height of the mother liquor in the mother liquor tank reaches a preset normal value.

If the liquid level reaches a predetermined normal value (e.g., via the above-described addition of fresh water), flow proceeds to step 507. In step 507, it is determined whether the liquid level height in the mixing tank is a low level, and if the liquid level height is below a predetermined value, proceed to step 508 to add a quantitative amount of clear water to the mixing tank, and then again determine the liquid level height in the mixing tank. If the liquid level in the mix tank is normal, proceed to step 509. In step 509, a measured amount of the mother liquor solution is added to the mixing tank. As mentioned above, in order to achieve the above-mentioned addition of a fixed amount of mother liquor solution, the present invention proposes to monitor the level of the disinfectant in the mixing tank by means of a first level meter. Therefore, the controller can control the clean water filling switch and the peristaltic pump arranged on the mixing tank according to the liquid level of the disinfectant in the mixing tank. When the disinfectant in the mixing tank is lower than a preset value (20cm), the controller firstly controls the clean water filling switch to be opened and a certain amount of clean water is filled, and the liquid level in the mixing tank gradually reaches normal. When the liquid level in the mixing tank reaches normal, the controller is utilized to control the peristaltic pump to pump quantitative mother solution into the mixing tank according to the proportion coefficient of the disinfectant so as to obtain the disinfectant with accurate proportion. After the above-described operation of step 509 is performed, the flow proceeds to step 510. In step 510, it is determined whether the pH of the sterilization fluid in the mixing tank reaches a predetermined value. If the ph is below the predetermined value, the process returns to step 509 where the addition of the mother liquor solution to the mixing tank is continued. If the pH value reaches the preset value, the process proceeds to step 511, and the medicine outlet valve is opened to discharge the medicine.

As for the ph control, as described above, the ph of the disinfecting liquid fully mixed in the mixing tank is detected by the ph detector, and the peristaltic pump for filling the mother liquid into the mixing tank is controlled by the controller according to the ph information. When the pH value does not reach the required pH value, the pH value information is transmitted to the controller to control the peristaltic pump to continuously fill the mother liquor into the mother liquor filling port until the pH value reaches the standard. Therefore, the proportioning scheme of the utility model realizes automatic proportioning operation, thereby obviously reducing labor cost and ensuring the disinfection effect of the disinfectant in the mixing tank.

In summary, the device for automatically proportioning the disinfectant in the mixing tank provided by the utility model can accurately proportion the disinfectant in the mixing tank through the combination of the first liquid level meter, the pH value detector and the controller, and can reduce the labor intensity of personnel while ensuring that the disinfectant waste is reduced. In addition, as mentioned above, the automatic disinfectant proportioning system of the present invention can support a platform management based on the use of the controller, for example, status information (including alarm notification when a fault occurs) can be pushed through remote monitoring and control. For example, when the dosage is insufficient, the system can automatically send an alarm about the insufficient dosage to a worker, so that the medicine can be supplemented in time. For another example, when some components (such as various valves or flow meters) in the system have faults, the system can also give an alarm in time and inform maintenance personnel to carry out early overhaul and troubleshooting, so that the later operation and maintenance cost of the equipment is reduced.
