In the exemplary embodiment of the application, the valve core gear of the slurry discharging rotary valve has no limit (the limit device is replaced by the magnetic element and the Hall element), so that the problems of motor heating, valve core gear abrasion and the like caused by locked rotor can be avoided. The position of the slurry discharging nozzle opposite to the slurry receiving cup and the position of the slurry discharging nozzle opposite to the residual water box are provided with the limiting devices, so that the slurry discharging nozzle only rotates in a limited area no matter clockwise or anticlockwise rotating, the rotating direction is only related to the opposite direction of the slurry discharging nozzle, signals of Hall elements only need to be detected after the rotating direction is determined, and the control logic is simpler.

Example two

If the angle between the open valve position and the closed valve position is set to be too large, the time for switching the state of the rotary valve is too long, so that the efficiency is influenced, if the angle is set to be too small, the pulp discharging port is too small, the efficiency of pulp discharging and residual water discharging is low, more time is required for discharging the same water, and the pulping period is influenced. The position of the slurry discharging nozzle opposite to the slurry receiving cup and the position of the slurry discharging nozzle opposite to the residual water box are 45 degrees, so that the slurry discharging liquid and the residual water discharging state can be switched quickly, the angle between the slurry discharging nozzle and the residual water discharging nozzle is smaller than the angle between a valve opening and a valve closing, and the condition that the direction of the slurry discharging nozzle can be switched firstly and then the state of a switch valve can be switched no matter the slurry discharging nozzle rotates clockwise or anticlockwise at each time can be guaranteed in a linkage mode.

In an exemplary embodiment of the present application, the first direction may be a counterclockwise direction, and the second direction may be a clockwise direction.
In the exemplary embodiment of the application, when the first motor starts to rotate clockwise, if the slurry discharging nozzle is not in a position opposite to the residual water box, the slurry discharging nozzle starts to rotate to the position of the residual water box and stops when the slurry discharging nozzle touches the second limiting device; if the slurry discharging nozzle is in the position opposite to the residual water box at the beginning, the slurry discharging nozzle does not rotate any more.
In the exemplary embodiment of the application, when the first motor starts to rotate anticlockwise, if the slurry discharging nozzle is not in a position of abutting against the slurry cup, the slurry discharging nozzle starts to rotate to a position of abutting against the slurry cup and stops when the first limiting device is touched; if the pulp discharging nozzle is in the position opposite to the pulp receiving cup at the beginning, the pulp discharging nozzle does not rotate any more.
In an exemplary embodiment of the present application, the first motor may be used to perform a linkage control of the valve core and the slurry discharging nozzle; the valve core can be a valve core capable of rotating 360 degrees;
the step of determining to drive the slurry discharging nozzle to rotate to the specified position according to the rotation angle and/or the rotation duration of the valve core and then controlling the valve core to continue to rotate in the original direction may include:
the first motor is controlled to continue to rotate towards the first direction or the second direction so as to drive the valve core to continue to rotate towards the original rotation direction until the first Hall element sends out a first Hall signal, and the first motor is controlled to stop rotating to open the valve;
when a valve closing signal is detected in the process of controlling the first motor to rotate towards the first direction or the second direction or in the process of discharging slurry or discharging residual water, the first motor is controlled to continue to rotate towards the original rotating direction so as to drive the valve core to continue to rotate towards the original rotating direction until the second Hall element sends out a second Hall signal, and the first motor is controlled to stop rotating so as to close the valve.
In an exemplary embodiment of the application, in the process of controlling the first motor to continue rotating in the original rotating direction, due to the different setting positions of the first hall element and the second hall element, the valve core may first pass through the second hall element, that is, first rotate to the closed valve position to close the valve, and only reach the first hall element in the process of continuing rotating, that is, rotate to the open valve position to open the valve.
In the exemplary embodiment of the application, similarly, after the valve closing signal is detected, in the process of controlling the first motor to continue to rotate in the original rotation direction, due to the different setting positions of the first hall element and the second hall element, the valve core may first pass through the first hall element, that is, first rotate to the valve opening position to realize the valve opening, and in the process of continuing to rotate, the second hall element may be reached, that is, rotate to the valve closing position to realize the valve closing.
In an exemplary embodiment of the application, when a valve opening signal is detected during the process of controlling the first motor to rotate clockwise (i.e. controlling the slurry discharging nozzle to rotate to a position facing the residual water box), the first motor may be controlled to continue to rotate clockwise to drive the valve core to rotate until the first hall element sends out a first hall signal, and the first motor is controlled to stop rotating to realize valve opening; when the valve core is in a valve opening state and the valve closing signal is detected, the first motor is controlled to continue to rotate clockwise to drive the valve core to rotate until the second Hall element sends out a second Hall signal to control the first motor to stop rotating, and the valve closing is achieved.
In an exemplary embodiment of the application, when the valve opening signal is detected during the rotation of the first motor in the counterclockwise direction (i.e., the rotation of the slurry discharging nozzle to the position where the slurry discharging nozzle is directly butted with the slurry cup), the first motor is controlled to continue to rotate in the counterclockwise direction to drive the valve core to rotate, at this time, the valve core passes through the second hall element first, so that the second hall element is triggered to send a second hall signal to close the valve, and the first motor continues to rotate in the counterclockwise direction until the first hall element sends a first hall signal to control the first motor to stop rotating to open the valve; when the valve core is in a valve opening state and the valve closing signal is detected, the first motor can be controlled to continue rotating in the anticlockwise direction (at this time, the gear ratio needs to be calculated in advance so as to avoid that the slurry discharge nozzle is blocked by the limiting device all the time to cause serious rotation blockage when the first motor rotates in one direction all the time in a linkage state, and therefore the motor is damaged), and the first motor can also be controlled to rotate in the opposite direction, namely the clockwise direction so as to drive the valve core to rotate until the second Hall element sends out a second Hall signal to control the first motor to stop rotating, so that the valve closing is realized.
In an exemplary embodiment of the present application, the method may further include:
and in the process of controlling the first motor to rotate towards the first direction or the second direction, when a valve opening signal or a valve closing signal is detected, controlling the first motor to stop rotating for a first preset time, and if the first Hall signal or the second Hall signal is not detected after the first preset time, controlling the first motor to continue to move until the first Hall signal or the second Hall signal is detected, and controlling the first motor to stop moving.
In an exemplary embodiment of the present application, the first preset time period may satisfy: 200-400ms.

Setting a forward control signal to be 0, setting a reverse control signal to be 1, starting the first motor to rotate anticlockwise, setting the forward control signal and the reverse control signal to be 1 simultaneously when detecting a valve opening Hall signal or a valve closing Hall signal, braking, and setting the forward control signal and the reverse control signal to be 0 simultaneously after braking for 200-400ms.
In an exemplary embodiment of the present application, the slurry nozzle may be switched first, and when the first motor starts to rotate clockwise, if the slurry nozzle is not facing the residual water box, the slurry nozzle starts to rotate to the residual water box and stops. If the slurry discharging nozzle is in the position opposite to the residual water box, the slurry discharging nozzle does not rotate. When the first motor starts to rotate anticlockwise, if the slurry discharging nozzle is not in the position of being in butt joint with the slurry cup, the slurry discharging nozzle starts to rotate to the position of the slurry cup and stops. If the slurry discharging nozzle is in the position opposite to the slurry receiving cup, the slurry discharging nozzle does not rotate any more.
In the exemplary embodiment of the application, when rotating clockwise or anticlockwise, if an open valve Hall signal or a close valve Hall signal is detected, the brake can be applied for 200-400ms to ensure stable stop, and the phenomenon that the inertia is too large to cause loose closing or less opening is prevented. If the valve is switched from the open state to the close state, the slurry discharging rotary valve can be closed by continuing to rotate in the previous rotating direction.
In the exemplary embodiment of the application, the valve core can also be controlled by the second motor alone and is not linked with the slurry discharging nozzle.
