Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A filter flushing control method, a filter flushing control apparatus, an electronic device, and a storage medium according to embodiments of the present invention will be described below with reference to the accompanying drawings.
It should be noted that, because the invention realizes the function of automatically executing the forward backwashing and the automatic pollution discharge of the medium filter according to the pollution condition by optimizing the layout of the electromagnetic valve. Before describing the filter flushing control method of the present invention in detail, it is necessary to explain the structural relationship between the filter and each solenoid valve. Fig. 1 is a system schematic of a water treatment apparatus 100 according to an embodiment of the present invention.
As shown in fig. 1, the water treatment apparatus 100 includes: a filter 13; and a first electromagnetic valve 3.1, a second electromagnetic valve 3.2, a third electromagnetic valve 3.3, a fourth electromagnetic valve 3.4 and a fifth electromagnetic valve 3.5, wherein an outlet of the first electromagnetic valve 3.1 and an inlet of the second electromagnetic valve 3.2 are respectively connected with an inlet of the filter 13, an outlet of the third electromagnetic valve 3.3, an inlet of the fourth electromagnetic valve 3.4 and an inlet of the fifth electromagnetic valve 3.5 are respectively connected with an outlet of the filter 13, and an outlet of the second electromagnetic valve 3.2 and an outlet of the fifth electromagnetic valve 3.5 are respectively connected with a sewage tank or a mine water tank.
It should be noted that, as one possible implementation manner, the water treatment apparatus 100 is specifically an intrinsic safety type water treatment apparatus, and may also be another type of water treatment apparatus, which is not limited in this embodiment.
FIG. 2 is a flow chart of a filter flush control method according to one embodiment of the present invention.
As shown in fig. 2, the filter flushing control method includes:
step 201, obtaining pressure values of a first pressure sensor and a second pressure sensor at two ends of the filter.
In this embodiment, the filter 13 has a water inlet and a water outlet, where the water inlet and the water outlet do not limit the inlet and outlet directions, and the water inlet can also serve as the water outlet, and similarly, the water outlet can also serve as the water inlet. In this embodiment, the filter 13 may be a media filter, wherein the media is a high water-based emulsion used in a hydraulic transmission system of a fully mechanized mining face. Of course, the medium is not limited thereto, and may be other substances.
Because the quality of raw mine water of different coal mines is different, in order to ensure that the quality of water produced by water treatment equipment keeps relatively consistent in different use places, the raw water needs to be filtered by a filter, and the filter is polluted under the influence of the quality of water or the service life in the use process. In order to maintain the filter in a normal filtering state, the filter needs to be cleaned and drained. In the embodiment of the invention, a first pressure sensor 11.2 and a second pressure sensor 11.3 are installed at two ends of the filter 13, wherein, taking the flowing direction of raw water of the water treatment equipment 100 as an example, the first pressure sensor 11.2 is close to the front end of the filter 13, and the second pressure sensor 11.3 is close to the rear end of the filter 13. When different sides inside the filter 13 are polluted, the side of the filter 13 needing to be cleaned can be judged according to the pressure value of the corresponding side pressure sensor. Here, the filter 13 may be subjected to a forward washing or a reverse washing, thereby achieving a cleaning effect on different sides of the filter 13. So-called normal washing, that is, washing the front end to the rear end side of the filter 13; the backwashing is to clean the rear end of the filter 13 to the front end side.
It should be noted that, here, the pressure values of the first pressure sensor 11.2 and the second pressure sensor 11.3 are uploaded to the electronic control system 24, and the electronic control system 24 is configured to control each electromagnetic valve according to the pressure values. In the water treatment apparatus 100 of the embodiment of the present invention, the signals of all the sensors are communicated to the electronic control system 24, and the electronic control system 24 is communicated to the monitoring center 25 through a communication protocol such as 485, modbus, etc. The electronic control system 24 controls the audible and visual alarm system 26 based on the operating conditions of the equipment. When abnormal conditions such as filter element blockage occur in the water treatment equipment 100, the sound-light alarm system 26 can realize quick alarm reminding of problems according to fault diagnosis, so that the defects of large environment noise of underground working surfaces and long inspection period of staff are overcome. Here, the monitoring center 25 may be a display control interface, which can display data of each sensor, the flow meter and the working state of each electromagnetic valve, and the monitoring center 25 also has a function of parameter setting, which can instruct the electronic control system 24 to implement other required functions.
Step 202, calculating a pressure difference between the second pressure sensor and the first pressure sensor according to the pressure value.
In this embodiment, in order to clearly determine whether the filter 13 needs to be washed forward, backwashed, or maintain a normal filtering state, the pressure difference between the second pressure sensor 11.3 and the first pressure sensor 11.2 needs to be calculated. Here, the body for performing the calculation is the electronic control system 24, and when the electronic control system 24 obtains the pressure values of the pressure sensors, the pressure values of the second pressure sensor 11.3 and the first pressure sensor 11.2 are automatically calculated according to a program set inside the system.
And step 203, comparing the magnitude relation between the pressure difference and a preset pressure threshold value, and outputting a comparison result.
In this embodiment, the preset pressure threshold may be 0, and when the pressure difference is greater than 0, it means that the pressure at the rear end of the filter 13 is greater than that at the front end, so that it may be determined that the side of the rear end of the filter 13 needs to be cleaned; when said pressure value is equal to 0, it means that the filter 13 is in the filtering condition and therefore does not need to be cleaned; when the pressure difference is less than 0, it means that the pressure at the front end of the filter 13 is greater than that at the rear end, and it can be determined that the front end side of the filter 13 needs to be cleaned.
It should be noted that, the determination of whether the filter needs to be cleaned is performed by comparing the pressure difference with the preset pressure threshold, but not exclusively, the contamination of the front end and the rear end of the filter may be determined by analyzing the water flow rate through the front end and the rear end of the filter and determining the water flow rate per unit time.
And step 204, generating electromagnetic valve combination information according to the comparison result.
In some embodiments, as a possible implementation manner, generating the solenoid valve combination information according to the comparison result may include: if the pressure difference is greater than the preset pressure threshold, generating the first electromagnetic valve combination information; if the pressure difference is equal to the preset pressure threshold, generating second electromagnetic valve combination information; and if the pressure difference is smaller than the preset pressure threshold, generating the third electromagnetic valve combination information.
Here, the first solenoid valve combination information, the second solenoid valve combination information, and the third solenoid valve combination information correspond to a forward washing state, a filtering state, and a backwashing state of the filter, respectively.
In this embodiment, the solenoid valve combination information does not indicate that different solenoid valves are selected for combination, but indicates that the switch states of the solenoid valves are marked after the different solenoid valves are selected, and the marks are regarded as one combination. For example, the first solenoid valve 3.1, the second solenoid valve 3.2, the third solenoid valve 3.3, the fourth solenoid valve 3.4, and the fifth solenoid valve 3.5 in the embodiment of the present invention are selected, and 1 is marked as on, and 0 is marked as off. The combination of the respective solenoid valves 3.1 to 3.5 may then be: 11000. 00111, 11001, 10110, etc. In this embodiment, the first solenoid valve combination information is: 10001; the second electromagnetic valve combination information is as follows: 10010; the third electromagnetic valve combination information is as follows: 01100.
and step 205, controlling the working state of each electromagnetic valve according to the electromagnetic valve combination information.
In some embodiments, as a possible implementation manner, the controlling the working state of each solenoid valve according to the solenoid valve combination information may include: if the electromagnetic valve combination information is first electromagnetic valve combination information, controlling to open a first electromagnetic valve and a fifth electromagnetic valve and close a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve; if the electromagnetic valve combination information is second electromagnetic valve combination information, controlling to open the first electromagnetic valve and the fourth electromagnetic valve and close the second electromagnetic valve, the third electromagnetic valve and the fifth electromagnetic valve; and if the electromagnetic valve combination information is third electromagnetic valve combination information, controlling to open the second electromagnetic valve and the third electromagnetic valve and close the first electromagnetic valve, the fourth electromagnetic valve and the fifth electromagnetic valve.
In this embodiment, taking the third electromagnetic valve combination information 01100 as an example, after the electronic control system 24 acquires the operating state information 01100 of the first to fifth electromagnetic valves 3.1 to 3.5 through the electromagnetic valve sensor, the electronic control system may issue control instructions to the first to fifth electromagnetic valves 3.1 to 3.5, respectively, so that the second and third electromagnetic valves 3.2 and 3.3 are opened, and the first, fourth and fifth electromagnetic valves 3.1, 3.4 and 3.5 are closed. Therefore, the raw water 27 is caused to flow from the rear end to the front end of the filter 13 via the third electromagnetic valve 3.3, and further flows to the sewage tank or the mine water tank via the second electromagnetic valve 3.2, thereby realizing a function of backwashing the filter 13. The functional principles of other forward washing and filtering are similar, and are not described in detail herein.
According to the filter flushing control method, the pressure values of a first pressure sensor and a second pressure sensor at two ends of the filter are obtained; calculating the pressure difference between the second pressure sensor and the first pressure sensor according to the pressure value; comparing the magnitude relation between the pressure difference and a preset pressure threshold value, and outputting a comparison result; generating electromagnetic valve combination information according to the comparison result; and controlling the working state of each electromagnetic valve according to the electromagnetic valve combination information. Therefore, the filter can automatically execute the functions of forward backwashing and automatic sewage discharge according to the pollution condition.
