[0002] The advection tank is a crucial component of the water treatment process, used to precipitate and remove suspended solids from the water. As a key component of the advection tank, the sludge suction vehicle is responsible for collecting and discharging the settled sludge. Traditional sludge suction vehicles often operate in a timed or fixed-speed mode, which presents the following issues: Regardless of the amount of sludge, the sludge suction trolley and sludge suction pump run at a fixed speed. When the sludge concentration is high, the sludge is not sucked thoroughly. When the sludge concentration is low, repeated operations cause energy waste.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application, its application, or use. Example 1

[0017] like Figure 1As shown, a sludge suction trolley for a horizontal flow tank comprises: a sludge concentration detection device 1, a sludge suction pump 2, a controller and a walking trolley 3 for driving the sludge suction pump 2 to move; The sludge concentration detection device 1 is configured to detect the sludge concentration at the sludge suction port of the sludge suction pump 2; The controller is configured to adjust the flow rate of the sludge suction pump 2 and the moving speed of the traveling vehicle 3 according to the concentration information input by the sludge concentration detection device 1 .

[0018] In this embodiment, the sludge concentration detection device 1 includes an ultrasonic sludge interface meter, which is used to detect the sludge concentration at the sludge suction port of the sludge suction pump 2. The signal output terminal of the ultrasonic sludge interface meter is connected to the signal input terminal of the controller. In other embodiments, other sludge concentration detectors capable of detecting sludge concentration can be used as the sludge concentration detection device 1.

[0019] This embodiment further includes a frequency converter. The mud suction pump 2 is driven by a driving motor. The frequency converter is connected to the signal output terminal of the controller. The frequency converter is used to adjust the flow rate of the mud suction pump 2 by controlling the speed of the driving motor.

[0020] The controller also includes an alarm, and the signal output end of the controller is connected to the alarm.

[0021] The sludge concentration at the sludge suction port of the sludge suction pump 2 is detected by the sludge concentration detection device 1 and transmitted to the controller. The controller obtains information on the concentration change within a preset time unit based on the obtained sludge concentration at the sludge suction port, and then adjusts the flow rate of the sludge suction pump 2 and the moving speed of the walking trolley 3. This can ensure sufficient sludge suction and improve sludge treatment efficiency, while avoiding ineffective operation of the sludge suction pump 2 and the walking trolley 3. The present invention greatly reduces energy consumption in the advection tank operation, reduces equipment loss, and extends service life. Example 2

[0022] This embodiment provides an adaptive control method for the advection tank sludge suction vehicle described in Example 1, which is executed by a controller, such as Figure 2 Shown, including: Obtaining the sludge concentration at the sludge suction port of the sludge suction pump 2 detected by the sludge concentration detection device 1; Calculating the concentration change within a preset time period according to the sludge concentration at the sludge suction port; In response to the sludge concentration at the sludge suction port of the sludge suction pump 2 and the concentration change within a preset unit time, the flow rate of the sludge suction pump 2 and the moving speed of the walking trolley 3 are adjusted.

[0023] In this embodiment, the flow rate of the sludge suction pump 2 and the moving speed of the walking trolley 3 are adjusted in response to the sludge concentration at the sludge suction port of the sludge suction pump 2 and the concentration change within a preset unit time, including: In response to the sludge concentration at the sludge suction port of the sludge suction pump 2 being less than or equal to the first preset value C0, the flow rate of the sludge suction pump 2 is set to the preset minimum flow rate Q min , the moving speed of the walking car 3 is the preset maximum speed V max ; In response to the sludge concentration at the sludge suction port of the sludge suction pump 2 being greater than or equal to the second preset value C1, the flow rate of the sludge suction pump 2 is set to the preset maximum flow rate Q max , the moving speed of the walking car 3 is the preset minimum speed V min ; In response to the first preset value C0 being less than the sludge concentration at the sludge suction port of the sludge suction pump 2 and less than the second preset value C1: When the concentration change within the preset time unit is greater than the preset concentration change value, first reduce the flow rate of the sludge pump 2 to the preset minimum flow rate Q at a rate of 5-10m³ / h. min , then 0.5-2m / min 2 The acceleration increases the moving speed of the walking car 3 to the preset maximum speed V max ; When the concentration change within the preset unit time equals the concentration change preset value, the flow of the sludge suction pump 2 and the moving speed of the walking trolley 3 are maintained unchanged; When the concentration change within the unit preset time is less than the concentration change preset value, first 2 The acceleration reduces the moving speed of the walking car 3 to the preset minimum speed V min Then increase the flow rate of the sludge pump 2 to the preset maximum flow rate Q at a rate of 5-10m³ / h max ; In response to the concentration not decreasing within the unit preset time, the alarm sounds an alarm.

[0024] Through the above control method, when the concentration is too low, the sludge pump 2 maintains the minimum flow rate, and the walking carriage 3 can move quickly, reducing ineffective energy consumption. When the sludge concentration at the sludge suction port of the sludge pump 2 is detected to be high, the sludge pump is set to the maximum flow rate, and the walking carriage 3 moves at a slower speed to ensure sufficient sludge suction. When the concentration is moderate, the difference between the concentration change per preset time and the preset value of the concentration change is used to adjust the sludge pump 2 and the walking carriage 3 in real time. If the concentration is detected to have not decreased within the preset time, the alarm will sound, reminding you to check whether the equipment is blocked or malfunctioning. Example 3

[0025] Based on the adaptive control method of the mud suction vehicle in the advection tank in Example 2, this embodiment provides an adaptive control system for the mud suction vehicle in the advection tank, including: The concentration detection module is configured to: detect the sludge concentration at the sludge suction port of the sludge suction pump 2 through the sludge concentration detection device 1; The data processing module is configured to: calculate the concentration change within a unit preset time period based on the sludge concentration at the sludge suction port of the sludge suction pump 2 detected by the sludge detection device; The control module is configured to adjust the flow rate of the sludge suction pump 2 and the moving speed of the walking vehicle 3 in response to the sludge concentration at the sludge suction port of the sludge suction pump 2 and the concentration change within a unit preset time.
