[0074] In some embodiments, as shown in FIG. 2, the quantitative liquid taking system 200 further comprises a first branch 240 and a second branch 250 between the first storage mechanism 210 and the control mechanism 220, the first branch 240 is communicated with the first storage mechanism 210 and the control mechanism 220, and the second branch 250 comprises a second storage mechanism 251, and the second storage mechanism 251 is communicated with the first storage mechanism 210 and the liquid receiving area 230.

[0075] In the embodiments, the quantitative liquid taking system 200 comprises a first branch 240 and a second branch 250 between the first storage mechanism 210 and the control mechanism 220, the first branch 240 is connected to the first storage mechanism 210 and the control mechanism 220, and the control mechanism 220 can control the quantitative taking of the medium in the liquid receiving area 230 through the first branch 240; the second branch 250 comprises a second storage mechanism 251 connected to the first storage mechanism 210 and the liquid receiving area 230, and through the second branch 250, the medium in the liquid receiving area 230 can be easily taken quantitatively in an amount equal to the capacity of the second storage mechanism 251, without the need for the sensor assembly 222 to control the valve assembly 221 to frequently switch states, which can shorten the time for quantitative liquid taking while improving the accuracy of the quantitative liquid taking system 200.

[0076] The first branch 240 is connected to the first storage mechanism 210 and the control mechanism 220, so that the medium in the first storage mechanism 210 can pass through the first branch 240 to the control mechanism 220 and be released into the liquid receiving area 230 under the control of the control mechanism 220 in a first weight value.

[0079] The second storage mechanism 251 is a storage tank or a storage box or a storage pool with a certain capacity.

[0080] Specifically, when the second storage mechanism 251 is not full of medium, the first storage mechanism 210 releases medium to the liquid receiving area 230 through the first branch 240, and at the same time, medium is injected into the second storage mechanism 251; when the second storage mechanism 251 is full of medium, the first storage mechanism 210 releases medium to the liquid receiving area 230 through the first branch 240, and medium will not flow into the second storage mechanism 251.

[0081] Optionally, the medium volume corresponding to the first weight information in the liquid receiving area 230 is less than the medium volume of the second storage mechanism 251, so that when a small dose of medium is needed, the medium can be quantitatively obtained through the first branch 240 and the control mechanism 220; and when a large dose of medium is needed, the medium can be directly released from the second storage mechanism 251 to the liquid receiving area 230, so that the time for the sensor assembly 222 of the control mechanism 220 to frequently open and close the valve assembly 221 can be reduced.

[0082] Optionally, a sensor can be arranged in the second storage mechanism 251 to obtain the mass of the medium released from the second storage mechanism 251 to the liquid receiving area 230. The sensor can be a pressure sensor, a flow sensor, or a liquid level meter, etc.

[0084] In these embodiments, the first driving mechanism 262 is arranged between the first storage mechanism 210 and the first branch 240 to drive the medium to flow from the first storage mechanism 210 to the control mechanism 220, the second branch 250 further includes the second driving mechanism 252 between the second storage mechanism 251 and the liquid receiving area 230, the second driving mechanism 252 being used to drive the medium to flow from the second storage mechanism 251 to the liquid receiving area 230, and the quantitative liquid taking system further includes the first valve 261 between the first storage mechanism 210 and the second branch 250, the first valve 261 being able to block the communication between the first storage mechanism 210 and the second storage mechanism 251, so that when the second storage mechanism 251 quantitatively discharges medium to the liquid receiving area 230, the influence of the medium in the first storage mechanism 210 is avoided, and the liquid taking precision of the quantitative liquid taking system 200 is improved.

[0085] When the second branch 250 releases the medium to the liquid receiving area 230, the first valve 261 needs to be closed to avoid the first storage mechanism 210 continuing to fill the medium to the second storage mechanism 251, resulting in the medium capacity in the liquid receiving area 230 being affected. When the first valve 261 is not closed, the medium in the metering system 200 is driven by the first driving mechanism 262; when the first valve 261 is closed, the first driving mechanism 262 can no longer drive the medium in the second branch 250 to flow, and the second branch 250 drives the medium to flow from the second storage mechanism 251 to the liquid receiving area 230 by the second driving mechanism 252.

[0089] In these embodiments, the first branch 240 further comprises a check valve 241 arranged between the first valve 261 and the control mechanism 220, which can reduce the risk of the medium in the first branch 240 entering the second storage mechanism 251 when the second storage mechanism 251 metering discharges the medium to the liquid receiving area 230, resulting in inaccurate metering results.

[0090] Since the first branch 240 and the second branch 250 are in communication with each other, in order to reduce the risk of the residual medium in the first branch 240 flowing back into the second storage mechanism 251 when the second branch 250 is enabled, resulting in the accuracy of the system metering being reduced, a check valve 241 can be arranged between the first valve 261 and the control mechanism 220 to avoid the medium in the first branch 240 flowing back into the second storage mechanism 251.

[0091] Optionally, the first valve 261 and the check valve 241 can be pneumatic ball valves, when the pressure in the pipeline reaches a threshold, the pneumatic ball valve is in the open state, and when the pressure in the pipeline does not reach the threshold, the pneumatic ball valve is in the closed state. When the second branch 250 needs to be activated, the first driving mechanism 262 can be closed, the pressure in the pipeline of the metering liquid system 200 decreases, and the two pneumatic ball valves are in the low-pressure closed state, and then the second driving mechanism 252 is driven, and the second driving mechanism 252 drives the medium in the second storage mechanism 251 to flow to the liquid receiving area 230.

[0092] In some embodiments, as shown in FIG. 2, the second branch 250 further comprises a non-metal pipe 253, which is connected to the first valve 261 and the second storage mechanism 251.

[0094] The medium in the metering liquid system 200 is NMP, which is applied to slurry particle size detection. In order to reduce the interference of metal impurities in the pipeline of the system on the slurry particle size detection, part of the metal pipeline can be replaced by a non-metal pipe 253.

[0097] Optionally, the second pressure sensor 2512 can be a ground pump, and the second storage tank 2511 is arranged on the ground pump. The change amount of the medium in the second storage tank 2511 can be displayed through the ground pump.

[0098] For example, the control mechanism 220 of the first branch 240 allows 1 kg of medium to enter the liquid receiving area 230 each time, and the second branch 250 can accommodate 100 kg of medium at most. If no second pressure sensor 2512 is arranged on the second storage mechanism 251, the second branch 250 is enabled, and in order to ensure the accuracy of the liquid receiving, 100 kg of medium is received in the liquid receiving area 230 each time. If 60 kg of medium needs to be received, the valve assembly 221 in the control mechanism 220 needs to be opened and closed for multiple times through the first branch 240 and the control mechanism 220. Through the second branch 250, the second pressure sensor 2512 can detect that 60 kg of medium is reduced in the second storage tank 2511, and it can be considered that 60 kg of medium has been obtained in the liquid receiving area 230.
