The embodiment of the application firstly provides a pulp pH value detection system. Fig. 1 is a schematic block diagram of an ore pulp pH detection system according to an embodiment of the present application. As shown in fig. 1, the pulp pH detection system may include: a pulp pH detection device 11, a mechanical assembly 12 connected to the pulp pH detection device 11, and a pH sensor 13.

When it is desired to detect the pH value of the pulp by means of the pH sensor 13, the pH sensor 13 may be mounted on the mounting. The mechanical assembly 12 may control the pH sensor 13 to move in a horizontal direction or a vertical direction under the control of the pulp pH detecting device 11, for example, the mechanical assembly 12 may control the pH sensor 13 to move in a horizontal direction to above a stirring tank containing pulp and control the pH sensor 13 to move vertically downward to put the pH sensor 13 into the pulp, or control the pH sensor 13 to move vertically upward to lift the pH sensor 13 from the pulp.

Based on the pulp pH detection system provided in the above embodiment, the embodiment of the present application further provides a pulp pH detection method. Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of a method for detecting pH of pulp according to an embodiment of the present application. In this embodiment, the main body of the pulp pH detection method may be the pulp pH detection device in the above embodiment. As shown in fig. 3, the method for detecting the pH value of the pulp may include S31 to S33, which are described in detail as follows:
s31: and if the pH value detection instruction is detected, sending a first control instruction to a mechanical component for controlling the movement of the pH sensor, wherein the first control instruction is used for indicating the mechanical component to put the pH sensor into ore pulp to be detected.
In this embodiment of the present application, when the pH of the pulp needs to be detected, the user may trigger the pH detection instruction to instruct the pulp pH detection device to start to detect the pH of the pulp. Specifically, the pulp pH detection device may include a display screen; alternatively, the pulp pH detection device may be connected to a display screen. The pulp pH value detection device can display a user interface comprising a first control through a display screen, and a user can trigger a pH value detection instruction by triggering the first control in the user interface. Based on the detection, when the pulp pH value detection device detects that a user triggers a first control in the user interface, the detection of the pH detection instruction is confirmed.
In one embodiment of the present application, the display screen may be a touch display screen. Triggering the first control in the user interface may include: click or double click on the first control. If the pulp pH value detection device detects that the user clicks or double clicks the first control in the user interface, the detection of the pH detection instruction is confirmed.
After the pulp pH value detection device detects the pH detection instruction, a first control instruction can be sent to the mechanical component connected with the pulp pH value detection device so as to instruct the mechanical component to put the pH sensor into the pulp to be detected.
In one possible implementation, the first control instruction may include: the first cylinder control command, the first motor control command and the second cylinder control command. Based on this, S31 may specifically include the steps of:
the first cylinder control instruction is sent to the cylinder and used for instructing the cylinder to control the piston rod of the cylinder to extend out so as to drive the pH sensor to vertically move upwards;
the first motor control instruction is sent to the motor, and the first motor control instruction is used for indicating the motor to rotate forward for a second time period so as to control the pH sensor to move above a stirring barrel filled with the ore pulp to be tested in the horizontal direction;
and sending a second cylinder control instruction to the cylinder, wherein the second cylinder control instruction is used for instructing the cylinder to control the piston rod of the cylinder to retract so as to drive the pH sensor to vertically move downwards, so that the pH sensor is placed in the ore pulp to be detected.
In this implementation manner, the second duration may be set according to actual requirements, which is not particularly limited herein. It should be noted that the motor rotates forward for the second period of time just can make the mechanical support drive the pH sensor to move from above the container containing the dirt cleaning liquid to above the stirring barrel containing the ore pulp. The dirt cleaning liquid can chemically react with dirt on the electrode surface of the pH sensor to enable the dirt to be separated from the electrode surface of the pH sensor, so that the dirt on the electrode surface of the pH sensor is cleaned.
S32: and acquiring and displaying the actual pH value of the ore pulp to be detected, which is acquired by the pH sensor.
In the embodiment of the application, the actual pH value of the ore pulp to be measured is a digital value, and the value of the actual pH value can be between 0 and 14. It should be noted that the pH sensor outputs an analog pH signal corresponding to an actual pH value of the pulp to be measured, including but not limited to: analog voltage signals or analog current signals, etc. The actual pH value of the pulp to be tested is finally displayed to the user by the pulp pH detection device, so in one embodiment of the present application, S32 may be specifically implemented by S321 to S322 shown in fig. 4, which is described in detail as follows:
s321: and acquiring an analog pH signal of the ore pulp to be detected, which is output by the pH sensor.
In this embodiment, the pH sensor may collect the analog pH signal of the pulp to be measured once every third time. The third duration may be set according to actual requirements, and is not particularly limited herein. The pH sensor is used for acquiring the simulated pH signal of the pulp to be measured in real time when the third time length is a unit time length.
In a specific application, the amplitude range of the analog pH signal output by the pH sensor may be set according to actual requirements. For example, if the analog pH signal is an analog voltage signal, the analog voltage signal may have an amplitude ranging from 0 to 10 volts (V), in this example, the analog voltage signal having an amplitude of 0V corresponds to a pH value of 0, and the analog voltage signal having an amplitude of 10V corresponds to a pH value of 14. If the analog pH signal is an analog current signal, the analog current signal may have an amplitude ranging from 4 to 20 milliamp (mA), in this example, the analog current signal having an amplitude of 4mA corresponds to a pH value of 0 and the analog current signal having an amplitude of 20mA corresponds to a pH value of 14.
In this embodiment, since the pH sensor may collect a plurality of analog pH signals, the pulp pH detecting device may obtain a plurality of analog pH signals collected by the pH sensor.
S322: and carrying out filtering treatment on the analog pH signal, and carrying out analog-to-digital conversion treatment on the analog pH signal after the filtering treatment to obtain the actual pH value of the ore pulp to be detected.
In a specific application, because the slurry is stirred in the stirring barrel unevenly, the analog pH signal output by the pH sensor may have a larger error, in order to improve the accuracy of slurry pH detection, after the slurry pH detection device obtains the analog pH signal output by the pH sensor, the obtained analog pH signals may be filtered, so that the analog pH signal deviating from the normal amplitude range is filtered from the analog pH signals. And then, the pulp pH value detection device can carry out analog-to-digital conversion treatment on each analog pH signal after the filtering treatment to obtain digital quantities (namely the actual pH value of the pulp to be detected) corresponding to each analog pH signal after the filtering treatment.
In one embodiment of the present application, a butterworth low pass filter may be configured in the pulp pH detection device. The pulp pH detection device may use a butterworth low-pass filter to perform a first (hardware) filtering process on each of the obtained analog pH signals. The Butterworth low-pass filter is a signal processing filter with a very flat frequency response curve of a passband, and is characterized in that the frequency response curve in the passband is maximally flat and has no ripple, and gradually drops to zero in a blocking band.
In another embodiment of the present application, in order to make the obtained analog pH signal have stronger interference immunity, further improve the accuracy of the pH value of the pulp obtained finally, and in order to save the hardware filtering cost, the pulp pH value detection device may further perform the second (on software) filtering process on each analog pH signal after the first filtering process based on the sliding average filtering method. Since the sliding average filtering method is the prior art, a detailed description of the filtering process is not repeated here.
In this embodiment, the pulp pH value detection device may perform analog-to-digital conversion processing on each analog pH signal after the second filtering processing, to obtain a digital value corresponding to each analog pH signal.
Specifically, the pulp pH value detection device may calculate the digital value corresponding to each analog pH signal after the second filtering process according to the following formula:
wherein the pH is 0 U is the digital quantity corresponding to the analog pH signal after the second filtering treatment 0 Is processed by the second filteringThe amplitude of the analog pH signal, U 2 For the maximum amplitude of the analog voltage signal output by the pH sensor, U 1 And M is the maximum value of the analog quantity which is allowed to be input by the pulp pH value detection device.
U is as follows 1 And U 2 The value range of the amplitude of the analog voltage signal output by the pH sensor is formed to be [ U ] 1 ,U 2 ]. By way of example and not limitation, U 1 Can be 0V, U 2 May be 10V.
M and 0 form the value range of the analog quantity which is allowed to be input by the pulp pH value detection device, namely [0, M ]. Wherein M may be determined according to the type of the pH detecting device, and is not particularly limited herein. For example, M may be 27648, 32767, 4000 or 4096, etc.
In one possible implementation, the pulp pH detection device may determine the average value of the digital quantities corresponding to each of all the analog pH signals as the actual pH of the pulp.
In another possible implementation, the pulp pH detection device may determine the median value of the digital quantities corresponding to each of all the analog pH signals as the actual pH of the pulp.
S323: and displaying the actual pH value of the ore pulp to be detected on a display screen.
In one embodiment of the present application, when the pulp pH detection device includes a display screen, the pulp pH detection device may directly display the actual pH of the pulp to be tested on its display screen.
In another embodiment of the present application, when the slurry pH is connected to the display screen, the slurry pH detection device may send the actual pH of the slurry to the display screen connected thereto, so that the display screen displays the actual pH of the slurry.
S33: and after the first duration of the first control command is sent, a second control command is sent to the mechanical assembly, and the second control command is used for indicating the mechanical assembly to lift the pH sensor from the ore pulp to be detected and placing the pH sensor into the dirt cleaning liquid.
In the embodiment of the application, the first time length is used for describing the residence time length of the pH sensor in the ore pulp. For example, the first duration may be greater than or equal to the fourth duration. In a specific application, the first duration may be set according to actual time requirements, which is not particularly limited herein. For example, the first duration may be 5 minutes.
In one possible implementation, the second control instruction may include: a first cylinder control command, a second motor control command, and a second cylinder control command. Based on this, S33 may specifically include the steps of:
after a first duration of the first control instruction is sent, sending the first air cylinder control instruction to the air cylinder, wherein the first air cylinder control instruction is used for instructing the air cylinder to control the piston rod of the air cylinder to extend so as to drive the pH sensor to vertically move upwards;
sending the second motor control instruction to the motor, wherein the second motor control instruction is used for instructing the motor to rotate reversely for a second time period so as to control the pH sensor to move to the upper side of a container filled with the dirt cleaning liquid in the horizontal direction;
and sending a second cylinder control instruction to the cylinder, wherein the second cylinder control instruction is used for instructing the cylinder to control the piston rod of the cylinder to retract so as to drive the pH sensor to vertically move downwards, and the pH sensor is placed in the dirt cleaning liquid.
It should be noted that the motor is reversed for the second period of time just to enable the mechanical support to drive the pH sensor to move from above the stirring barrel containing the ore pulp to above the container containing the dirt cleaning liquid.
As can be seen from the above, in the method for detecting the pH value of the pulp provided in the present embodiment, when the pH value detection instruction is detected, a first control instruction may be sent to a mechanical component for controlling the movement of the pH sensor, so as to instruct the mechanical component to insert the pH sensor into the pulp to be detected to detect the pH value of the pulp to be detected, and display the actual pH value of the pulp to be detected acquired by the pH sensor; and a second control command may be sent to the mechanical assembly after the first duration of the first control command is sent to instruct the mechanical assembly to lift the pH sensor from the slurry to be tested and place it in the foulant cleaning solution. The pH value of the ore pulp to be detected is detected by placing the pH sensor into the ore pulp to be detected when the pH value of the ore pulp to be detected is required to be detected, and the pH sensor is lifted from the ore pulp to be detected and placed into the dirt cleaning liquid after the actual pH value of the ore pulp to be detected is acquired for a first time, so that on one hand, the pH sensor is not placed into the ore pulp for a long time, and the possibility of electrode scaling of the pH sensor can be reduced; on the other hand, after the actual pH value of the ore pulp is collected, the pH sensor is placed into the dirt cleaning liquid for cleaning, so that dirt on the electrode surface of the pH sensor can be cleaned, the pH value of the ore pulp can be accurately detected by the pH sensor, and the service life of the pH sensor is prolonged.
