The quantitative container 3 is located above the storage tank 2, and the quantitative container 3 has a base 31, a surrounding wall 32 extending upward from the periphery of the base 31, and a top disposed at a top edge of the surrounding wall 32. The base U, the surrounding wall 32' and the top seat 33 cooperatively define an accommodating space 34. The top seat 33 is provided with a slit 332 for the quantitative cover 331, spaced apart from the screw hole 331 and provided for the liquid level sensor 6, and a liquid discharge or When the accommodating space 34 of the dosing container 3 is injected, the air can be sucked into or discharged from the air conditioning hole 333 of the accommodating space 34 in a cooperative manner. The base 31 is provided with a second through hole 311 and a third through hole 312 which are spaced apart and are respectively disposed through the injection return pipe 4 and the process discharge unit 8. The injection return pipe 4 is disposed on the storage tank 2 and the quantitative container 3 and communicates with each other. The end of the injection return pipe 4 connected to the quantitative container 3 is extended by the third through hole 312. The container 3 is housed in the space 34. In the present embodiment, a siphon phenomenon is generated in order to facilitate the combination with the metering cover 7. The section of the injection return pipe 4 located in the accommodating space 34 is vertical. The delivery pump 5 is disposed on the injection return pipe 4, and drives the liquid stored in the storage tank 2 to move through the injection return pipe 4 to the accommodating space 34 in the quantitative granulator 3. When the delivery pump 5 is stopped, the liquid can still be returned to the storage tank 2 via the injection return pipe 4. The liquid level sensor 6 is connected to the top seat 33 of the metering container 3 and extends into the accommodating space 34 of the metering container 3 through the first hole 332, and is detected and stored in the accommodating space 34. The height of the liquid inside. In this embodiment, the liquid level sensor 6 is a float type liquid level sensing switch. The dosing cover 7 has a closed end and an open end. The quantification cover 7 has a thread on the outer peripheral wall and cooperates with the screw hole 331 on the top seat 33 of the dosing container 3 to open the dosing cover 7. The end is screwed into the accommodating space 34 of the metering container 3, and a mask is formed at one end of the injection return pipe 4 which also protrudes into the accommodating space 34. The open end 10 of the ration cover 7 is the most The bottom edge is below the bottom edge of the level sensor 6. The process discharge sheet 8 has a discharge pipe 8 that is connected to the base 31 of the dosing container 3 and penetrates into the dosing container 3 through the second perforation 311 of the base 31 and communicates with the accommodation space 34 thereof. An electric valve 82 for controlling opening and closing of the discharge pipe 81 is provided on the discharge & 81. It should be noted that the wheel pump 5, the electric valve 82, and the liquid level sensor 6 are electrically connected to a programmable controller (not shown), and the controller is The signal returned by the liquid level sensor 6 is processed, and the corresponding opening and closing of the delivery pump 5 and the electric valve 82 are controlled. The actuation cycle of the present invention is as follows: First, the controller closes the electric valve 82 of the process discharge unit 8 and causes liquid to be discharged through the discharge pipe 81, and then activates the delivery pump 5 to allow liquid to pass from the storage tank. 2 flowing through the injection return pipe 4 to the dosing container 3 until the liquid reaches a first liquid level 〇: as shown in FIG. 3, the liquid level will touch the liquid level sensor 6' and the liquid level The sensor 6 then transmits a signal to inform the controller that the liquid level in the quantitative container 3 has reached the first liquid level α'. At this time, the controller will close the signal after receiving the signal. The delivery pump 5 prevents the liquid from flowing into the metering container 3. In view of the above, since the electric valve 82 is still in the closed state, the discharge pipe 81 is also in a closed state, and since the storage tank 2 is located below the quantitative container 3, by atmospheric pressure and the liquid itself In the relationship of gravity, the metering cover 7 will cooperate with the injection return pipe 4 to generate a siphon phenomenon, and gradually return the liquid into the storage tank 2, and cause the liquid in the metering container 3 to start to pass through the injection return pipe. 4 flows back into the 13258562 storage tank 2 until the siphon phenomenon disappears, that is, the liquid in the quantitative container 3 flows back into the storage tank 2 through the injection return pipe 4 until 7 the liquid level in the quantitative container 3 It reaches the flute gas level south degree β as shown in FIG. According to the above, after the above operation is completed, a predetermined amount of liquid is stored in the quantitative container 3 and the discharge pipe 81, and when the quantitative liquid output is required, the controller opens the electric valve 82 and The liquid in the dosing container 3 is output by the discharge pipe 81. As can be seen from FIG. 3, since the size cover 7 is rotated by the screw holes 331 of the top seat 33 of the outer container wall of the outer container wall 3: the inside of the container 3 is quantitatively When the liquid output is adjusted, it is only necessary to rotate the metering cover 7 to change the depth of the metering container 3, and the second liquid level β' can be changed to change the amount of liquid stored in the metering container 3. (ie the amount of liquid output) is quite easy to operate. However, it should be noted that the bottom cover of the metering container 7 must be lower than the top edge 41 of the injection return pipe and form a political mask for the injection back to the β 4 . The siphon phenomenon can be produced smoothly. The heavy liquid addition system of the moon does not use any electrode type, and V1* does not cause accidental contact due to moisture in the grain, and the present invention utilizes the size cover 7 and the injection return pipe 4 Produced in cooperation. The suction sees out the excess liquid in the metering container 3, so that the amount of liquid in the volume container is maintained. The liquid level sensor 6 is only the final liquid level in the auxiliary sag valley 3 (the second liquid level is cold) and is still determined by the amount of | 7 and the physical principle of siphoning 12 . The method of the liquid level is better and more accurate than the method of using the electrode type sensor to set the monitoring liquid level, thereby increasing the accuracy of the output. The above-mentioned 'quantitative liquid addition system of the present invention is summarized by using the amount of 3 疋3; the $7 纟 mask is also formed at the end of the injection return pipe 4 which extends into the $3 container 3 The siphon phenomenon and the excess liquid is sucked from the quantitative container 3 until the siphon phenomenon disappears, and the liquid remaining after the predetermined amount of liquid left in the accommodation space 34 of the quantitative container 3 is passed through the process. The discharge pipe 81 of the discharge unit 8 is discharged to form a quantitative output of the liquid, and the screw-type coupling relationship between the quantitative cover 7 and the top seat 33 of the quantitative container 3 enables the quantitative cover 7 to be rotated by the quantitative cover 7 Adjusting the depth into the quantitative container 3 to determine the amount of output liquid, making the adjustment of the output liquid amount easier, and the present invention mainly performs the liquid level setting by the physical principle (siphon action), and there is no It is indeed possible to achieve the object of the present invention by using a 3-electrode type sensor which may cause a mis-touch due to moisture and affect the amount of liquid output. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are all It is still within the scope of the invention patent.
