In the process of water treatment, solid-liquid separation is a key link, which directly affects the effect of subsequent treatment process and the final water quality of the effluent. The plate and frame rotary filter is a high-efficiency solid-liquid separation equipment, and it is also necessary to monitor the operation status of the equipment.

DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0013] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0014] See also Figure 1-Figure 2 As shown, an equipment operation monitoring system for an ultra-deep rotary filter mainly includes a data sensor, a data acquisition module 1 and a control unit, which is suitable for a plate-and-frame rotary filter device. The plate-and-frame rotary filter device includes a transmission mechanism and a flushing device. The transmission mechanism includes a filter plate, a filter screen is arranged on the filter plate, a motor is arranged in the transmission mechanism, and the filter plate can be driven to rotate by the motor. A flushing control system 9 is arranged in the flushing device, which can control the flushing frequency of the flushing device. The flushing control system 9 includes a PAC controller 12, a flushing pump 13, a flow controller 14 and an adjustable nozzle 15. The flushing mode of the flushing device can be controlled by programming the PAC controller 12. The flushing mode is divided into a conventional flushing mode and a high-pressure flushing mode. In the conventional flushing mode, the PAC controller 12 controls the flushing pump 13 and the flow controller 14, so that the pressure value of the flushing water flow after being sprayed out from the adjustable nozzle 15 is 5MPa. The output flow rate can be increased by the flow controller 14 and the flushing pump 13 to adjust the flushing frequency. The pressure value of the flushing water flow can be adjusted between 5MPa-10MPa, and the interval time can be turned on and set in the conventional flushing mode. The interval time can be customized according to specific needs. When the interval time is adjusted to 0, the flushing device automatically flushes the filter plate continuously and uninterruptedly. If the interval time is turned off, the flushing device will not automatically flush the filter plate. When the filter plate is blocked, the PAC controller 12 turns on the high-pressure flushing mode, and adjusts the maximum output flow rate through the flow controller 14 and the flushing pump 13 to make the water flow pressure reach 10MPa, and continuously flushes the filter plate until the blockage of the filter plate is cleared. The adjustable nozzle 15 can also be controlled by the PAC controller 12, so that the internal baffle plate blocks the adjustable nozzle 15, thereby reducing the caliber of the adjustable nozzle 15, which can further increase the water flow pressure, thereby strongly flushing the stubborn residue on the filter plate that is not easy to flush.

[0015] Among them, the data sensor includes a water quality sensor 2, a speed sensor 3 and a pressure sensor 4. The above sensors are all connected to the data acquisition module 1. The data information collected by the sensor is converted into a digital signal through the data acquisition module 1, and the data acquisition module 1 transmits the converted digital signal to the control unit. The control unit includes a PLC programmable controller 5, a frequency converter 6, a host computer 7 and a sound alarm 8. The PLC programmable controller 5 can issue instructions to the frequency converter 6, and the host computer 7 can adjust the parameters of the PLC programmable controller 5 and control the PLC programmable controller 5 to issue instructions. The PLC programmable controller 5 can control the flushing frequency and rotation speed of the plate-frame rotary filter device, as well as the start and stop of the plate-frame rotary filter device, and the data acquisition module 1 uploads the digital signal to the host computer 7, and provides a human-machine interaction interface 10 through the display of the host computer 7, and displays the filter plate operation status, water quality parameters, flushing frequency and other information of the plate-frame rotary filter device in the human-machine interaction interface 10, and can remotely control the rotation speed of the filter plate and the flushing frequency of the flushing device from the human-machine interaction interface 10, as well as control the start and stop of the entire plate-frame rotary filter device. First, the water quality sensor The water quality sensor 2 monitors the concentration, turbidity and other parameters of the suspended matter in the filtered water, and determines whether the filter screen plate is working normally according to the parameters of the suspended matter in the filtered water. Since the filter screen on the filter screen plate is usually made of stainless steel or other corrosion-resistant materials, the filter screen plate may be deformed or damaged due to long-term operation or external impact, thereby affecting the filtering effect. Severe deformation may even affect the rotation stability of the filter screen plate. When the water quality sensor 2 detects that the parameters such as the concentration of suspended matter and / or turbidity in the filtered water are abnormally exceeded, the water quality sensor 2 transmits the signal of the abnormal parameter exceeding the standard to the data acquisition module 1. The data acquisition module 1 then transmits the signal to the control unit, which controls the plate and frame rotary filter equipment to stop running. At the same time, the host computer 7 displays the abnormal information of the filter plate in the human-computer interaction interface 10 in the form of a red exclamation mark. At the same time, the PLC programmable controller 5 issues an instruction to the sound alarm 8, causing the sound alarm 8 to emit a continuous and uninterrupted sound warning reminder until the staff clicks the red exclamation mark in the human-computer interaction interface 10 to view the abnormal information. The sound warning reminder of the warning module will be closed to prevent the staff from not checking or forgetting to check the equipment abnormal information in time.

[0016] Among them, the speed sensor 3 in the data sensor is installed on the rotating mechanism of the plate-frame rotary filter device, and the speed sensor 3 is used to monitor the rotation speed of the filter plate in real time, and the rotation speed information of the filter plate is uploaded to the data acquisition module 1, and uploaded to the host computer 7 in the control unit through the data acquisition module 1, and displayed in the human-machine interaction interface 10, and the inverter 6 in the control unit is connected to the motor of the filter plate, and the rated power, rated current, rated voltage and other basic parameters of the inverter 6 are set, and the control mode of the inverter 6 is set, such as V / F control, vector control, etc., and the speed regulation range of the inverter 6 is set, so that the PLC programmable controller 5 can control the speed of the motor through the inverter 6, and can directly click the remote control control unit through the human-machine interaction interface 10, so as to achieve the purpose of remotely controlling the rotation speed of the filter plate, and the rotation speed information of the filter plate is obtained by the speed sensor 3, and the rotation speed of the filter plate is observed to be consistent with the rotation speed set by the inverter 6. If there is an inconsistency, it may be caused by the following reasons, such as motor failure, motor failure or motor damage will cause the filter plate to fail to operate normally; or the transmission The failure of the transmission system, such as the damage or loosening of the transmission parts such as the transmission chain or gears, may cause the filter plate to rotate unstably or stop. It may also be a bearing failure. When the bearing is severely worn or damaged, it will also cause the filter plate to rotate inflexibly or stop. It may also be due to the blockage of the filter plate, resulting in floating objects affecting the rotation of the filter plate, causing the filter plate speed to decrease. Therefore, if the speed sensor 3 detects that the rotation speed of the filter plate is inconsistent with the rotation speed set by the frequency converter 6, the speed sensor 3 transmits the information to the PLC programmable controller 5 through the data acquisition module 1, and then the PLC programmable controller 5 sends a signal to the upper computer 7, and sends a reminder to the staff through the human-machine interaction interface 10, which is displayed in the form of a yellow exclamation mark, and the sound alarm 8 will emit a prompt sound of abnormal speed. The PLC programmable controller 5 determines whether it affects the use and whether it needs to be stopped for maintenance as soon as possible based on the difference between the set speed of the inverter 6 and the actual speed of the filter plate. If it needs to be stopped for maintenance, the stop option is selected on the human-machine interaction interface 10 to stop the operation of the control plate and frame rotary filter device, and then the staff checks the integrity of the above components and repairs the faulty components.

[0017] The pressure sensor 4 in the above-mentioned data sensor can monitor the pressure change of the water flow after filtering during the operation of the filter plate, so as to judge whether the filter plate is blocked or overloaded. The pressure sensor 4 is connected to the data acquisition module 1, so that the data acquisition module 1 can display the water pressure information detected by the pressure sensor 4 on the human-computer interaction interface 10 through the host computer 7. The real-time pressure value and the historical pressure vertical change curve are displayed in the human-computer interaction interface 10, so that the staff can intuitively understand the pressure change, and the staff can use the human-computer interaction interface 10 to control the pressure. The LC programmable controller 5 issues instructions to enable the PLC programmable controller 5 to control the flushing frequency of the flushing device and the rotation speed of the filter plate. When the filter plate is blocked, the flow rate of the water flow is reduced and the resistance is increased, which will cause the pressure of the water flow to drop. By setting the upper pressure threshold and the lower pressure threshold in the PLC programmable controller 5, when the water flow pressure drops to the set lower pressure threshold, it means that the pressure value is abnormal. The pressure sensor 4 will transmit the abnormal pressure value to the host computer 7 through the data acquisition module 1, so that the abnormal pressure value is displayed in the human-computer interaction interface 10, and the sound alarm 8 A warning sound of abnormal pressure value will be issued once. At the same time, since the PLC programmable controller 5 is connected to the flushing control system 9 in the flushing device, the PLC programmable controller 5 can transmit signals to the flushing control system 9, so that the flushing control system can be informed of the abnormal pressure value. At this time, the PLC programmable controller 5 controls the motor speed to decrease through the frequency converter 6. At the same time, after the flushing control system 9 receives the signal of abnormal pressure, it will increase the flushing frequency and the pressure of the flushing water flow will also be relatively increased until the PLC programmable controller 5 detects that the water flow pressure has returned to the normal pressure value range, and then transmits a signal to the flushing control system 9, and at the same time, the filter plate is restored to the normal operating speed. The flushing control system 9 receives the signal command and also restores the flushing device to the normal flushing frequency. When the pressure sensor 4 detects that the water flow pressure exceeds the upper pressure threshold, it may be caused by the damage of the filter plate. The pressure sensor 4 will transmit the data of the abnormal pressure value to the host computer 7 through the data acquisition module 1, and display it on the human-computer interaction page for the staff to observe, and at the same time, the plate-frame rotary filter equipment is controlled to stop running through the PLC programmable controller 5, waiting for the staff to inspect it.

[0018] Since the water flow in the use environment of the plate and frame rotary filter equipment may contain solid particles and corrosive liquids, a membrane filter is also provided on the pressure sensor 4 and the water quality sensor 2. The membrane filter can effectively protect the pressure sensor 4 and the water quality sensor 2 to prevent damage or adhesion and corrosion, thereby extending the service life of the sensor and avoiding affecting the real-time data detection of the plate and frame rotary filter equipment.

[0019] In addition, a communication module 11 is connected to the control unit, and a signal is transmitted to a remote mobile terminal through the communication module 11. The remote mobile terminal downloads an app so that the remote mobile terminal can observe the operating status of the plate and frame rotary filter device through the display interface of the app, and can control the flushing frequency and filter plate rotation speed of the plate and frame rotary filter device, as well as the start and stop of the plate and frame rotary filter device through the operation interface of the app. After issuing an instruction through the app operation interface, the signal is transmitted to the communication module 11 through the remote mobile terminal, and then the communication module 11 transmits the instruction to the PLC programmable controller 5, and the PLC programmable controller 5 issues instructions to the plate and frame rotary filter device, thereby realizing remote real-time monitoring and remote control. In addition, the communication module 11 can also send various abnormal information and prompt sounds to the remote mobile terminal, so that the abnormal status of the equipment can be monitored at the first time through the remote mobile terminal, so that corresponding solutions can be made at the first time.

[0020] When in use, open the app on the remote mobile terminal, and through the human-machine interface 10 of the app, the operating status of the plate-frame rotary filter device can be observed. The human-machine interface 10 can display the operating status of the filter plate of the plate-frame rotary filter device, water quality parameters, water pressure curves, and current flushing frequency and other information for staff to observe. When it is necessary to adjust parameters such as the filter rotation speed or flushing frequency, the staff only needs to click the corresponding option on the human-machine interface of the app to send a signal to the communication module 11 on the control unit through the remote mobile terminal, and then the communication module 11 transmits the information instruction to the PL C programmable controller 5, since the PLC programmable controller 5 is connected to the flushing control system 9 in the flushing equipment, and the PLC programmable controller 5 is also connected to the frequency converter 6, the various parameters in the plate-frame rotary filter device can be adjusted through the PLC programmable controller 5, such as adjusting the rotation speed of the filter plate and adjusting the frequency of the flushing device, and since the PLC programmable controller 5 is connected to the start-stop switch of the plate-frame rotary filter device, the start and stop of the plate-frame rotary filter device can also be controlled through the human-machine interface. When the data sensor detects abnormal parameters of floating objects in the water, abnormal water pressure or filter When the rotation speed of the screen plate is abnormal, the information will be transmitted to the PLC programmable controller 5 through the data acquisition module 1, and then transmitted to the human-machine interaction interface 10 of the host computer 7 through the PLC programmable controller 5, and a corresponding prompt sound will be issued at the same time. At the same time, the communication module 11 will transmit the data information to the app of the remote mobile terminal, and then display it in the human-machine interaction interface 10 of the app, and accompanied by a prompt sound, the staff will be reminded through the remote mobile terminal. In this way, even if the staff is not present due to individual circumstances, the staff's remote mobile terminal can observe the real-time data through the human-machine interaction interface 10 of the app, and then adjust the various parameters of the plate-frame rotary filter device in time through the operation interface in the human-machine interaction interface 10. In addition, since the PLC programmable controller 5 in the control unit will automatically make corresponding response plans according to different abnormal data, even if there are no staff, the control unit will control the rotation speed of the filter plate of the plate-frame rotary filter device and the flushing frequency of the flushing device, and when necessary, the control unit will control the plate-frame rotary filter device to stop running, which can effectively avoid damage to the equipment, and no manual operation is required, and the staff can be reminded to repair the equipment in time.

[0021] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
