[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] The purpose of the present invention is to provide an intelligent control system for medical wastewater treatment, comprising a buffer tank, a plurality of decay tanks and a PLC controller, wherein the buffer tank and the decay tank are both connected to the PLC controller; like Figure 1 As shown, a buffer tank inlet and a buffer tank outlet are provided on the side wall of the buffer tank; a plurality of decay tanks are provided with decay tank inlets and decay tank outlets on the side walls; the buffer tank inlet is used to connect to the wastewater discharge end, the buffer tank outlet is connected to the decay tank inlet through a pipe, the decay tank outlet is used to discharge wastewater that meets the discharge standards, and electric valves are provided on the pipes connecting the buffer tank outlet and the decay tank inlet and the pipes of the decay tank outlet. The electric valves are connected to the electric valve control assembly through a circuit, and the electric valves open the drain pipe when receiving a discharge signal and close the drain pipe when receiving a closing signal.
[0019] The PLC controller includes an electric valve control component, a timing control component, and a water pump control component; the buffer tank and the decay tank are both provided with a liquid level sensor, which is connected to the electric valve control component; the buffer tank and the decay tank are both provided with a submersible pump, which is connected to the water pump control component; a timer is provided in the decay tank, which is connected to the timing control component, and decay timing is performed when the decay tank meets the liquid level requirements.
[0020] Furthermore, it also includes a cloud processing management center, where the acquisition and control signals of the PLC controller are uniformly uploaded to the cloud processing management center through the data transmission module. All decay cell signals and operating status, including videos, are uploaded to the system's cloud processing management center through the network or 4G / 5G module, and the cloud processing management center summarizes the data and records all status.
[0021] Furthermore, it also includes a display module, which is connected to the PLC controller and is used to display the water level information of the liquid level sensor and the time information of the timer.
[0022] Furthermore, it also includes a resistance detection alarm device connected to the submersible pump, which is used to monitor the operation of the submersible pump, and to issue an early warning and enable another submersible pump to work when the submersible pump is damaged.
[0023] Furthermore, it also includes a data storage module, which is connected to the PLC controller and is used to store the emission records of the decay pool; the emission records include emission flow, emission time and sampling specific activity data.
[0024] Specifically, the water inlet and outlet processes of this system are as follows: 1. Water inlet When starting work, medical water slowly flows into the buffer tank. The water level signal in the buffer tank is fed back to the local operation screen and PLC controller in real time by the liquid level sensor. Drainage is carried out according to the water level signal of the buffer tank. The water level signal setting and display can be operated on the screen or in the central control room.
[0025] When flowing out from the buffer tank to the decay tank, the valves corresponding to the decay tanks can be opened as needed, or all valves can be opened at the same time to flow into the corresponding decay tanks. As long as sewage flows into the decay tank, the timing starts, accurate to seconds, and the timing information can be fed back to the local control screen and PLC controller. The timing information can feedback the time when the tank is full or the exact time after the tank is full. In this process, the timing information of all decay tanks can be displayed and fed back on the local operation screen or the host computer. By setting the time for the decay tank to be placed, the operator can be reminded to handle the next process or by setting the water level signal to automatically close the valve at the location, and the inflow of medical water can be cut off in time.
[0026] When the liquid level of a decay pool reaches the upper limit, it means that the decay pool is full, and the corresponding electric valve is closed. At the same time, the decay pool enters the decay timing (adjustable, up to 180 days, adjustment is calculated in seconds, the main interface will display the decay time such as: "2 days, 12 hours, 35 minutes and 20 seconds").
[0027] The decay pool can be used cyclically, without priority, and the order of use is one, two, and three. Once the commonly used water pump in the buffer pool is damaged, an alarm will be triggered through resistance detection, and another water pump will be enabled to work. In normal operation, it is designed to run alternately, and all states of the water pump can be sent to the PLC controller.
[0028] 2. Drainage When the decay date of a decay pool reaches the discharge date, the corresponding decay pool output pipeline valve is opened for discharge, and the submersible pump in the decay pool is running at the same time as the valve is opened. When the output water quality of the decay pool does not meet the standard, the decay pool water pump is stopped and the corresponding valve of the decay pool is closed. After the water quality meets the discharge standard after testing, the water of the corresponding decay pool is discharged. If the decay time is up and the activity is unqualified, the discharge is suspended and re-tested after a certain period of time. When the liquid level in all decay pools reaches the set lower limit level, the pump is automatically stopped.
[0029] It also includes monitoring the operation of all submersible pumps. If a submersible pump or electric valve is damaged, an alarm will be issued and displayed on the local operation screen and the centralized control center. The display module will display red for route and liquid level, and green for the conduction status of the electric valve; When the liquid level in the pool is at the upper limit, the electric valve is in the closed position, and the level gauge displays the liquid level, if the liquid level changes (too high or too low), an alarm will be issued and displayed on the screen, and the alarm signal can be sent to the operator's mobile phone. At the same time, the time protection of the level gauge can be adjusted when the water pump is draining. Once the timeout is exceeded, an alarm will be issued and displayed on the display.
[0030] A camera is installed within the preset range of the decay pool to monitor the changes and dynamic operation conditions within the decay pool and transmit them to the cloud processing management center in real time.
[0031] The above process is the water intake and drainage process in automatic operation mode. The system can also be manually debugged.
[0032] On the other hand, an intelligent control method for medical wastewater treatment is provided. Figure 2 As shown, the intelligent control system for medical wastewater treatment is used for control, and the specific steps include the following: When the system starts working, the medical wastewater flows into the buffer tank, and the liquid level sensor in the buffer tank detects the water level signal and feeds it back to the electric valve control component of the PLC controller in real time, and the wastewater is discharged to the decay tank according to the water level signal; When sewage starts to flow into the decay pool, the timer is started, and the timing information is fed back to the display module and the timing control component. When the liquid level in the decay pool reaches the upper limit, the corresponding electric valve is closed, and the decay pool enters the decay timing; When the decay date of the decay pool reaches the discharge date, the electric valve at the output port of the decay pool opens for discharge. If the decay date is reached but the activity is unqualified, the discharge is suspended and retested within a fixed time.
[0033] The emission standards are: 1. Time: The storage time of water quality in each decay pool can be accurate to the minute and second through the timer in the PLC (for example, 100 days, or 60 days. This time can be set manually on the touch screen because the reaction time characteristics of chemical water in each hospital are different). 2. Water quality detector: A water quality detector is installed at the end of the decay pool. The water quality detector detects whether the various parameters of water quality discharge and the pH value are within the range required by the state. It no longer accepts a single time test to check whether the discharge meets the standards.
[0034] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
