In this embodiment, when drainage plate 4 was horizontal, the inclination of 6 lateral walls of dashpot was 45 degrees, and when the piston rod of cylinder was flexible, drainage plate 4 pivoted total angle was more than or equal to 90 degrees to can make the water in the dashpot 6 topple over and go out by the number.

As shown in fig. 1, a main valve 21, a water inlet valve 22 and a flow meter 23 are sequentially installed on the water feeding pipe 2 along the water flow direction, and the water inlet valve 22 is a normally open type electromagnetic valve. The frame 1 is provided with a controller 7, a first delay circuit and a second delay circuit. The controller 7 is electrically connected with the drain valve 3 through a first delay circuit, and the controller 7 is electrically connected with the water inlet valve 22 through a second delay circuit.

When the flow measured by the flowmeter 23 reaches the value set in the controller 7, the controller 7 controls the second delay circuit to work, so that the water inlet valve 22 is closed, the closing time depends on the time set by the second delay circuit, and the time is matched with the time for the air cylinder to drive the drainage plate 4 to rotate, so that the water adding box body is switched.

When the flow measured by the flowmeter 23 reaches the value set in the controller 7, the controller 7 controls the first delay circuit to work, so that the drain valve 3 is opened, the time set by the first delay circuit is maintained, and after the time is over, the drain valve 3 returns to the normally closed state again.

The main tank 11 and the auxiliary tank 12 are both provided with a water level protection device 9, and the water level protection device 9 comprises an electronic liquid level meter 91, a water level controller 92 and a third delay circuit.

The third delay circuit returns the drain valve 3 to the closed state after being maintained for a certain period of time.

The first delay circuit, the second delay circuit and the third delay circuit only need to realize corresponding functions, and since the delay circuits themselves belong to the prior art, the specific structures thereof are not described herein again.

The use principle is as follows: when the drainage plate is used, the drainage plate 4 is obliquely arranged, the height of the first water falling port 42 is lower than that of the second water falling port 43, and a piston rod of the air cylinder is in a contraction state.

The main valve 21 is opened, water enters the water feeding pipe 2, falls into the buffer tank 6 from the water feeding pipe 2, then flows along the second water dropping port 43 toward the first water dropping port 42, and falls into the main tank 11 through the first water dropping port 42. The liquid level in the main tank 11 gradually rises and the flow rate measured by the flow meter 23 increases. When the data measured by the flow meter 23 reaches the value set in the controller 7, the controller 7 controls the first delay circuit and the second delay circuit to be opened and controls the operation of the cylinder.

The piston rod of the cylinder extends to drive the drainage plate 4 to rotate, and when the drainage plate rotates, the height of the second water falling port 43 is gradually reduced, and the height of the first water falling port 42 is gradually increased. When the piston rod of the cylinder stops extending, the inclination angle of the drainage plate 4 is greater than or equal to 45 degrees, for example, 60 degrees, so as to ensure that water can completely fall out along the buffer slot 6 and fall into the auxiliary tank 12 through the second water falling port 43.

When the first delay circuit is opened, the drain valve 3 is switched from a normally closed state to be opened, and water in the main tank 11 is discharged into the material through the drain valve 3. And the water inlet valve 22 is closed from a normally open state when the second delay circuit is opened, and the water adding is stopped. And the drainage plate 4 is turned from the initial state to the time when the lateral wall of the buffer groove 6 close to the first water falling port 42 reaches the horizontal state by the cylinder, so that the water falling onto the buffer groove 6 can not fall into the main tank 11 from the first water falling port 42 through the lateral wall when the water feeding pipe 2 discharges water again.

When the water inlet valve 22 is opened again, the flow meter 23 continues to count on the original reading, when the reading of the flow meter 23 is increased by a preset value, the controller 7 controls the first delay circuit, the second delay circuit and the air cylinder to work again, the delay time is the same as that in the working condition, when the movement of the air cylinder is changed into the contraction of the piston rod, the direction of the drainage plate 4 is driven to rotate and the initial position is restored, and at the moment, the main box 11 is weighed again. And the process is repeated in a reciprocating way.

By changing the set value of the controller 7, the amount of the ingredient can be changed each time it is weighed.

When the amount of ingredients required is larger than the individual capacity of the main tank 11 and the sub-tank 12, the water level protection device 9 operates.

The working principle of the water level protection device 9 is as follows: the electronic level meter 91 detects the water level in the main tank 11, and when the water level is higher than the set value, the water level controller 92 controls the third delay circuit to operate, so that the drain valve 3 is opened to drain water, and a part of water is firstly put into the material to be mixed, thereby avoiding overflow of the water level in the main tank 11. After the water discharge time exceeds the set time of the third delay circuit, the water discharge valve 3 returns to the closed state, the water in the main tank 11 continues to increase, and if the set water level is reached again, the water level controller 92 controls the third delay circuit to be opened again until the dosing is completed. Similarly, when the water pipe 2 adds water to the sub-tank 12, the electronic level gauge 91 in the sub-tank 12 detects the water level in the sub-tank 12, and when the water level is higher than the set value, the water level controller 92 controls the third delay circuit in the sub-tank 12 to operate, so that the drain valve 3 is opened to drain water for a time period exceeding the set time of the third delay circuit. The water discharge valve 3 is closed, and the operation is circulated.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
