[0024] Embodiment 1

[0025] This embodiment provides a waste liquid classification discharge device, which includes: a classification drainer 100 and a drain control assembly. A plurality of independent classification drain pipes 200 are communicated with the classification drainer 100. The classification drainer 100 is communicated with the processing chamber 400 through a main drain pipe 300. The drain control assembly includes a first sensor 503, a first control valve 501 provided on the main drain pipe 300, and second control valves 502 respectively provided on each classification drain pipe 200. The first sensor 503 is used to detect the pH value of the liquid in the classification drainer 100, and the second control valve 502 is used to control the on-off of the classification drain pipe 200 where it is located according to the pH value.

[0026] Please refer to Figure 1As shown, in this embodiment, the classification drainer 100 is connected to the processing chamber 400 through the main drain pipe 300. The processing waste liquid in the processing chamber 400 flows into the classification drainer 100 through the main drain pipe 300 for classified discharge. Specifically, the classification drainer 100 is communicatively provided with a number of mutually independent classification drain pipes 200. Each classification drain pipe 200 is provided with a corresponding first sensor 503 and a second control valve 502. The first sensor 503 is used to detect the pH value of the waste liquid in the classification drainer 100. The second control valve 502 controls the on-off of the classification drain pipe 200 where it is located according to the pH value detected by the first sensor 503, so as to achieve the classified discharge of the waste liquid. It can be understood that waste liquids with different chemical properties such as acidic or alkaline may be generated in different steps during the machining of the CNC machining machine. When the waste liquid enters the classification drainer 100, the first sensors 503 in each classification drain pipe 200 detect the pH value of the waste liquid simultaneously. When it is detected that the pH value of the waste liquid is greater than 7, the second control valve 502 corresponding to the alkaline classification drain pipe 200 is opened to discharge and collect the alkaline liquid; when it is detected that the pH value of the waste liquid is less than 7, the acidic classification drain pipe 200 is opened to discharge and collect the acidic liquid. Similarly, when it is detected that the pH value of the waste liquid is equal to 7, the second control valve 502 of the conventional waste liquid discharge pipeline is opened for discharge. It should be noted that the number of the classification drain pipes 200 can be increased or decreased according to the actual processing steps. For example, strong acid classification drain pipes 200, weak acid classification drain pipes 200, conventional waste liquid classification drain pipes 200, weak base classification drain pipes 200, strong base classification drain pipes 200, etc. can be set to further classify the discharged waste liquid. The number of the classification drain pipes 200 can be set according to the requirements, and this embodiment does not make any restrictions. The above classification drainer 100 can achieve the classified discharge of the waste liquid. However, when the first sensor 503 or the second control valve 502 fails and the second control valve 502 fails to close in time or correctly, the discharged waste liquid may enter the wrong pipeline, which may cause the equipment to malfunction. For example, when acidic liquid enters the classification drain pipe 200 for discharging alkaline liquid, it may react with the liquid in the pipeline to generate precipitation and block the pipeline, affecting the discharge of the waste liquid. At the same time, since the waste liquids discharged from different classification drain pipes 200 have different acid-base degrees, the pipeline materials used are also different to avoid the reaction between the waste liquid and the pipeline. However, when the waste liquid enters the wrong pipeline, it may react with the pipeline, resulting in the corrosion or embrittlement of the classification drain pipe 200, and it is easy to occur safety accidents such as pipeline breakage and liquid leakage. Therefore, in this embodiment, the main drain pipe 300 is provided with a first control valve 501 to play a role of control and buffering. When discharging the waste liquid, the first control valve 501 is in the closed state. At this time, all the second control valves 502 are also closed. When discharging the waste liquid, the first control valve 501 is first opened. After the waste liquid enters the classification drainer 100, the pH value of the waste liquid is detected by the first sensor 503, and the corresponding second control valve 502 is opened according to the pH value of the waste liquid.When another processing step is carried out in the processing chamber 400 of the processing machine tool and another kind of processing waste liquid needs to be discharged, first close the first control valve 501 to achieve overall drainage control and ensure that the waste liquid in the classification drainer 100 is completely discharged. At this time, the first sensor 503 cannot detect the liquid, and the corresponding second control valve 502 closes. After confirming that the second control valve 502 is completely closed, open the first control valve 501 and repeat the above classification drainage steps. By setting the first control valve 501 to play a buffering role, it is ensured that the first control valve 501 is opened for drainage buffering only after all the second control valves 502 are completely closed, avoiding the waste liquid from entering the wrong pipeline. When the second control valve 502 fails, the first control valve 501 can also be closed in time to stop the drainage, ensuring the safety of the entire waste liquid classification discharge device.

[0027] Optionally, in some embodiments of this embodiment, a buffer tank 600 is serially arranged on the main drain pipe 300, and the buffer tank 600 is located between the processing chamber 400 and the first control valve 501.

[0028] Please refer to Figure 1 As shown, in this embodiment, a buffer tank 600 is arranged on the main drain pipe 300 to temporarily store the discharged waste liquid. The first control valve 501 is arranged at the bottom of the buffer tank 600. After the first control valve 501 is closed, the waste liquid discharged from the processing chamber 400 is temporarily stored in the buffer tank 600 to ensure the continuous progress of the processing operation. In addition to buffering the waste liquid discharged from the processing chamber 400, the buffer tank 600 can also buffer the waste liquid flowing back from the classification discharger. When all the second control valves 502 on the classification drain pipe 200 are closed, it may cause the undrained waste liquid to flow back. At this time, the buffer tank 600 can prevent the flowing-back waste liquid from flowing back into the processing chamber 400, ensuring the safety of the equipment.

[0029] Optionally, in some embodiments of this embodiment, the number of the first sensors 503 is multiple, and the multiple first sensors 503 are arranged at the classification drain pipe 200 in one-to-one correspondence.

[0030] Please refer to Figure 1 As shown, in this embodiment, each classification drain pipe 200 is provided with a first sensor 503, and each first sensor 503 corresponds to the second control valve 502 on the classification drain pipe 200 in one-to-one correspondence to achieve independent control and ensure the classification discharge effect.

[0031] Optionally, in some embodiments of this embodiment, the drain control assembly further includes a second sensor 504, and the second sensor 504 is used to detect the pH value of the liquid inside the buffer tank 600.

[0032] Please refer to Figure 1As shown, in this embodiment, the second sensor 504 is disposed within the buffer tank 600 for detecting the pH value of the waste liquid in the buffer tank 600. The first control valve 501 can control the on-off of the main drain pipe 300 according to the pH value detected by the second sensor 504, thereby playing a role in controlling the discharge of waste liquid. At the same time, the first sensor 503 and the second sensor 504 form a double verification. When discharging waste liquid, the pH value detected by the first sensor 503 is compared with the pH value detected by the second sensor 504. When the difference between the two exceeds the threshold, the first control valve 501 and the second control valve 502 are simultaneously closed to stop the liquid discharge. After the operator checks whether the liquid discharge is normal and performs adjustment and maintenance, subsequent operations are carried out to prevent the waste liquid from entering the wrong classification drain pipe 200 and damaging the equipment.

[0033] Optionally, in some implementation manners of this embodiment, the liquid discharge control assembly further includes a temperature sensor 505, and the temperature sensor 505 is used for detecting the temperature of the liquid inside the buffer tank 600.

[0034] Please refer to Figure 1 As shown, in this embodiment, a temperature sensor 505 for detecting the temperature of the waste liquid is disposed within the buffer tank 600, facilitating the operator to monitor the temperature of the waste liquid in real time.

[0035] Optionally, in some implementation manners of this embodiment, both the first control valve 501 and the second control valve 502 are pneumatic valves.

[0036] In this embodiment, the first control valve 501 and the second control valve 502 adopt any existing form or commercially available pneumatic valves. The specific structure of the pneumatic valve is not an improvement point of this practical new type. Its specific structure can refer to the existing pneumatic valve mechanism and is not limited here. The pneumatic valve has a high degree of automation and can achieve automatic control through a pneumatic actuator, improving production efficiency. This automation includes not only remote control but also automatic control, and can be adapted to the first sensor 503 and the second sensor 504 to achieve automatic adjustment and control, thus significantly improving the waste liquid discharge efficiency. Moreover, the operation of the pneumatic valve is simple, and only by controlling the opening and closing of the air source, the valve can be opened and closed. This feature makes the pneumatic control valve easy to operate and maintain. Since the pneumatic-manual conversion mechanism on the pneumatic control valve is flexibly and reliably assembled, it can conveniently realize the operation mode conversion from pneumatic to manual or from manual to pneumatic at any position during the opening and closing process of the gate valve. When a failure occurs in the solenoid valve, its control circuit or the air supply system, it can be quickly converted to the manual operation state to ensure the normal operation of the circuit, avoid accidents, and thus improve the safety and reliability of the system.

[0037] Optionally, in some implementation manners of this embodiment, the waste liquid classification discharge device further includes a liquid discharge detection assembly.

[0038] Optionally, the liquid drainage detection assembly includes a plurality of liquid flow meters 700, which are respectively arranged on the main liquid drainage pipe 300 and each classified liquid drainage pipe 200.

[0039] In this embodiment, liquid flow meters 700 are respectively arranged on the main liquid drainage pipe 300 and the classified liquid drainage pipes 200. When there is no liquid leakage, the amount of liquid flowing through the main liquid drainage pipe 300 and the classified liquid drainage pipes 200 is the same. When the amount of liquid flowing through the classified liquid drainage pipe 200 is less than that of the main liquid drainage pipe 300, liquid leakage may occur. The operator can timely judge whether there is liquid leakage according to the measurement results of the flow meter and carry out maintenance. At the same time, the liquid flow meters 700 on each classified liquid drainage pipe 200 can also be combined with the first sensor 503 on the pipeline to judge whether the waste liquid enters the wrong pipeline. When the liquid flow meters 700 on multiple classified liquid drainage pipes 200 all detect the passage of liquid, it is determined that the waste liquid enters the wrong pipeline, which is convenient for the operator to adjust in time.

[0040] Optionally, in some embodiments of this embodiment, the buffer tank 600 is provided with a cleaning port.

[0041] In this embodiment, a cleaning port is opened on the buffer tank 600, which is convenient for the operator to clean the inner wall of the buffer tank 600. It can be understood that the discharged waste liquid may react with the liquid remaining on the inner wall of the buffer tank 600 to generate crystalline dirt, which may affect the use effect of the buffer tank 600 after long-term use. At this time, the operator can open the cleaning port to clean the buffer tank 600 to avoid dirt accumulation.

[0042] Optionally, in some embodiments of this embodiment, a sealing cover is provided at the cleaning port.

[0043] In this embodiment, the sealing cover seals the buffer tank 600 to prevent the discharged waste liquid from leaking and improve the safety during liquid drainage.

[0044] In summary, the present utility model provides a waste liquid classification discharge device, which includes: a classification liquid discharger 100 and a liquid discharge control component. A number of mutually independent classification liquid discharge pipes 200 are communicatedly arranged on the classification liquid discharger 100. The classification liquid discharger 100 is communicated with a processing chamber 400 through a main liquid discharge pipe 300. The liquid discharge control component includes a first sensor 503, a first control valve 501 arranged on the main liquid discharge pipe 300, and second control valves 502 respectively arranged on each classification liquid discharge pipe 200. The first sensor 503 is used to detect the pH value of the liquid in the classification liquid discharger 100, and the second control valve 502 is used to control the on-off of the classification liquid discharge pipe 200 where it is located according to the pH value. By respectively arranging the first control valve 501 and the second control valve 502 on the main liquid discharge pipe 300 and the classification liquid discharge pipes 200, dual control is achieved. By detecting the pH value of the discharged waste liquid through the first sensor 503, the corresponding second control valve 502 is opened according to the detected data to achieve the classification discharge of the waste liquid. When discharging the liquid, the first control valve 501 plays a buffering role to ensure that the first control valve 501 is opened for liquid discharge only after all the second control valves 502 are completely closed, so as to avoid the waste liquid from entering the wrong pipeline. When the second control valve 502 fails, the first control valve 501 can also be timely closed to stop the liquid discharge, ensuring the safety of the entire waste liquid classification discharge device.
