[0064] When the nut block 50015 moves back and forth, it will drive the rack 50016 to move back and forth, the rack 50016 drives the fourth gear 50023 to rotate back and forth in a circular motion, the fourth gear 50023 drives the rocker arm to rotate back and forth in a circular motion, the rocker arm drives the gear ring 5003 to rotate back and forth, when the gear ring 5003 rotates back and forth, it will drive the third gear 5002 to rotate back and forth, the reciprocating rotation of the third gear 5002 will drive the rotating rod 500 and the flexible strip 5001 to rotate back and forth, and the flexible strip 5001 continuously strikes the bottom of the annular filter plate 3007, so that the dust and gravel stuck in the annular filter plate 3007 can be knocked down to avoid long-term blockage of the annular filter plate 3007.

[0065] Embodiment three:

[0066] The present embodiment is different from the first embodiment in that a delivery pipe 50017 is fixedly connected to the annular steel pipe 5006 , and a nozzle 50018 is fixedly connected to the outside of the annular steel pipe 5006 .

[0067] The above technical solution is explained as follows: the delivery pipe 50017 is connected to the tap water pipe, or the delivery pipe 50017 is connected to a water pump set up outside. The water pump draws water from the water source and delivers it to the annular steel pipe 5006, and finally sprays it out through the nozzle 50018. The water sprayed by the nozzle 50018 can impact the outside of the third gear 5002, wash away the mud and sand on the third gear 5002, and allow the third gear 5002 to fully engage with the ring gear 5003. The water entering the annular steel pipe 5006 can also dissipate heat to the arc sleeve 5005 and the annular steel pipe 5006, because the arc sleeve 5005 slides back and forth on the outside of the annular steel pipe 5006, and friction generates heat.

[0068] Embodiment 4:

[0069] The present embodiment is different from the first embodiment in that a control system is provided in the present embodiment, and the control system can automatically adjust the running speed of the sand excavation component, the flow rate of the cleaning water, the discharge time, etc. according to parameters such as the feed flow rate of the sand washing machine, the internal load conditions, and the turbidity of the cleaning water, so as to achieve efficient, energy-saving, and precise sand washing operations, and ensure that the sand washing quality is stable and the equipment operates safely and reliably.

[0070] The specific technical solutions are as follows, including:

[0071] Material flow sensor: installed at the feed inlet of the sand washing tank 100, used to monitor the flow of sand entering the sand washing tank 100 in real time, using a Doppler flowmeter or other .

[0072] Equipment load sensor: installed on the motor 2001 or key transmission components of the sand washing tank 100, for example, a strain gauge pressure sensor is used to measure the torque of the motor shaft to reflect the load condition inside the equipment and output a load signal (T, unit: N·m).

[0073] Washing water turbidity sensor: installed near the drain outlet of the sand washing tank 100, used to detect the turbidity of the water discharged after washing. A photoelectric turbidity sensor can be used to output a turbidity signal (C, unit: NTU).

[0074] Controller: A programmable logic controller (PLC) or an industrial control computer (IPC) is used as the core control unit to receive the above sensor signals and output control signals according to a preset control algorithm.

[0075] Frequency converter: connected to the motor 2001 of the sand washing tank 100, adjusts the speed of the motor 2001 according to the frequency signal output by the controller, thereby changing the operating speed of the sand washing machine.

[0076] Electric regulating valve: installed on the water inlet pipe of cleaning water, the opening is controlled by the current signal output by the controller to adjust the flow of cleaning water.

[0077] Discharge solenoid valve: installed at the discharge port of the sand washing tank 100, its opening and closing time is controlled by the controller to control the discharge process.

[0078] The above technical solution is explained as follows:

[0079] At startup, the controller first initializes and calibrates each sensor to ensure that the sensor can accurately measure the output signal, collects the flow signal Q of the material flow sensor, the load signal T of the equipment load sensor and the turbidity signal C of the cleaning water turbidity sensor at a fixed sampling period (Δt, for example 100ms), and stores them in the corresponding registers.

[0080] First of all, the sand washing machine running speed control method is as follows:

[0081] Calculate the target running speed based on the material flow:

[0082] Set the base running speed to (Unit: r / min), this speed is the minimum speed to ensure the sand washing effect under standard working conditions;

[0083] Calculate the flow correction factor ,in Design standard flow

[0084] Target running speed ;

[0085] Speed ​​limit range: and They are the minimum and maximum operating speeds allowed by the sand washing machine, to prevent the sand washing efficiency from being affected by too low a speed or the equipment from being damaged by too high a speed;

[0086] Fine-tune according to equipment load: Calculate load correction factor ,in is the torque value corresponding to the standard load;

[0087] Target running speed after fine-tuning ,in is the weight coefficient of the load on the speed (e.g. 0.1);

[0088] Check the speed range again and output the control signal to the inverter. The inverter runs at the target speed. The power supply frequency of the motor 2001 is adjusted to change the running speed of the sand washing machine.

[0089] The cleaning water flow control method is as follows:

[0090] First, calculate the initial cleaning water flow rate based on the material flow rate: Set the basic cleaning water flow rate to (Unit: m h).

[0091] Calculate the flow correlation coefficient , initial target cleaning water flow .

[0092] Adjustment based on wash water turbidity feedback: Setting turbidity threshold (e.g. 50NTU), calculate the turbidity deviation , calculate the turbidity correction factor (when hour, ;

[0093] Final target cleaning water flow ,in is the weight coefficient of the effect of turbidity on the flow rate of cleaning water (for example, 0.5). The controller outputs a control signal to the electric regulating valve to adjust the flow rate of cleaning water to

[0094] The discharge control method is as follows: Set the discharge cycle (e.g. 5min) and discharge duration (e.g. 30s);

[0095] After each discharge cycle , the controller outputs a signal to open the discharge solenoid valve for a duration of Material process.

[0096] In summary, in this embodiment, the controller monitors the sensor signals and equipment operation status signals in real time, such as the temperature and current of the motor 2001. When an abnormal situation occurs, such as the material flow is suddenly too large or too small (exceeding the set flow range threshold), the equipment load is too high (exceeding a certain proportion of the rated load, such as 120%), the turbidity of the cleaning water does not meet the standard for a long time (exceeding the set turbidity threshold and lasting for more than a certain period of time, such as 10 minutes), or the temperature of the motor 2001 is too high (exceeding the maximum allowable temperature), the controller immediately sends an alarm signal and takes corresponding protective measures, such as reducing the running speed of the sand washing machine, stopping the cleaning water supply, stopping the discharge, etc., and recording the fault information for subsequent analysis and maintenance.

[0097] This control system can dynamically adjust the operating speed and cleaning water flow of the sand washing machine according to actual working conditions by real-time monitoring of multiple parameters such as material flow, equipment load and cleaning water turbidity. Compared with the traditional fixed parameter control method, it is more energy-saving and efficient, and can effectively reduce energy consumption and production costs. The precise discharge control and fault monitoring mechanism can ensure the continuity and stability of sand washing operations, improve product quality, reduce equipment downtime, and extend equipment life. The system has strong adaptability and self-adjustment capabilities, can cope with changes in different sand properties and production environments, and improve the overall intelligence level and automation level of the sand washing machine. The above control system is only an example. In actual applications, it may be necessary to further optimize and improve it according to the specific model, specifications, working environment and production requirements of the sand washing machine. In addition, during the implementation process, it is also necessary to consider factors such as the installation position of the sensor, the stability of signal transmission, the programming implementation of the controller, and the debugging and maintenance of the system.
