Specifically, one end of the input branch pipeline is connected to the input main pipeline, and the other end is connected to the liquid inlet 210 of the filter unit 200.

[0078] Furthermore, the carbon fiber spinning solution filtering device comprises:

[0079] The detection module detects the total amount of the carbon fiber spinning solution to be filtered and transmits the detected total amount parameters to the analysis module;

[0080] The analysis module receives the total amount parameter of the stock liquid detected by the detection module, matches it with the set total amount value of the stock liquid, so as to obtain the number of filter units 200 required to work, and transmits the number parameter of the filter units 200 obtained by the analysis to the control module;

[0081] The control module receives the number parameters of the filter units 200 analyzed by the analysis module, and controls the corresponding number of filter units 200 to work.

[0082] Furthermore, the detection module can also detect the residual amount of the carbon fiber spinning solution being filtered, and transmit the residual amount parameters to the analysis module;

[0083] The analysis module receives the raw liquid residual parameter detected by the detection module and matches it with the set raw liquid residual value to obtain the number of filter units 200 that need to be closed, and transmits the number parameter of the filter units 200 obtained by the analysis to the control module;

After receiving the total amount parameter, the analysis module matches it with the total amount value of the solution set in the system, and obtains the number of filter units 200 that need to work according to the matching result. For example, if the total amount of the detected carbon fiber spinning solution is 10 cubic meters, the preset total amount value of the solution of 10 cubic meters or close to 10 cubic meters is searched in the system, and the number of filter units 200 that need to work is obtained according to the matching result. The obtained number parameter of the filter unit 200 is transmitted to the control module, and the control module controls the control valves on the input branch pipeline and the output branch pipeline of the corresponding number of filter units 200 to open. If the control valve installed on the input branch pipeline and / or the output branch pipeline is a solenoid valve, and there is only a solenoid valve, the solenoid valve is directly controlled to open; if the control valve installed on the input branch pipeline and / or the output branch pipeline is a manual valve, and there is only a manual valve, the control module will output and display the quantity parameter so that the staff can manually open it; if both a solenoid valve and a manual valve are installed on the input branch pipeline and / or the output branch pipeline, the control module will control the solenoid valve to open and output and display the quantity parameter and the parameters of the opened solenoid valve at the same time, and the staff will open the manual valve on the corresponding pipeline according to the output information.

[0086] In this embodiment, the detection module detects the residual amount of the carbon fiber spinning solution during the filtering process, and transmits the detected residual amount parameters of the carbon fiber spinning solution to the analysis module. After receiving the residual amount parameters, the analysis module matches the residual amount value of the solution set in the system, and obtains the number of filter units 200 that need to be closed according to the matching result. For example, if the residual amount of the detected carbon fiber spinning solution is 3 cubic meters, the preset value of 3 cubic meters or close to 3 cubic meters of residual amount is searched in the system, and the number of filter units 200 that need to be closed is obtained according to the matching result. The obtained number parameters of the filter units 200 are transmitted to the control module, and the control module controls the control valves on the input branch pipelines and output branch pipelines of the corresponding number of filter units 200 to be closed. If the control valve set on the input branch pipeline and / or the output branch pipeline is a solenoid valve, and there is only a solenoid valve, the solenoid valve is directly controlled to close; if the control valve set on the input branch pipeline and / or the output branch pipeline is a manual valve, and there is only a manual valve, the control module will output and display the quantity parameter so that the staff can manually close it; if both a solenoid valve and a manual valve are set on the input branch pipeline and / or the output branch pipeline, the control module controls the solenoid valve to close and outputs and displays the quantity parameter and the parameter of the closed solenoid valve, and the staff closes the manual valve on the corresponding pipeline according to the output information. After stopping the work, the filter unit 200 can determine whether it needs to be disassembled and cleaned according to the degree of dirtiness.

[0087] Furthermore, the time monitoring module monitors the use time of the filter unit 200 and transmits the time parameters obtained by monitoring to the analysis module;

[0088] The analysis module receives the time parameters transmitted by the time monitoring module, compares them with the preset time, and transmits the comparison results to the control module;

[0089] The control module controls the control valves provided on the input branch pipeline and the output branch pipeline of the corresponding filter unit 200 to be closed, and the filter unit 200 is disassembled and cleaned.

[0090] Further, the analysis module receives the time parameter transmitted by the time detection module, and transmits the time parameter to the judgment module provided in the analysis module;

[0091] A judgment module receives the time parameter transmitted by the analysis module, judges that the time reaches the preset time, and transmits the judgment result to the control module;

[0092] The control module receives the judgment result of the judgment module and controls the corresponding filter unit 200 to stop working.

[0093] In this embodiment, the control device of the carbon fiber spinning solution filtering device further includes a time monitoring module, which detects the use time of the filter unit 200 and compares the detected time parameter with the set time parameter. If the use time reaches the set time, it is necessary to close the control valves on the input branch pipe and the output branch pipe of the filter unit 200, and remove the filter unit 200 from the mounting frame 100 for cleaning. In this process, it can be determined whether a new filter unit 200 needs to be installed as needed to ensure the uninterrupted operation of the filtering device and the working efficiency of the filtering device.
