[0041] The embodiments of the present application disclose a feeding and degumming pipeline system.

[0042] Please refer to Figure 1 , an embodiment of a feeding and degumming pipeline system provided in the embodiments of the present application includes:

[0043] A feeding device and a degumming device.

[0044] The feeding device includes a material pipeline 1, a raw material pump 11, and at least one material branch pipe 13; one end of the material pipeline 1 is connected to the output end of the raw material pump 11 through a first raw material control valve 12; the input end of the raw material pump 11 is connected to a raw material supply source 100; one end of the material branch pipe 13 is connected to the material pipeline 1, and a meter 14 and a second raw material control valve 15 are arranged thereon. The raw material supplied by the raw material supply source 100 enters the material pipeline 1 through the raw material pump 11 and the first raw material control valve 12, and then enters the corresponding material branch pipe 13 from the material pipeline 1. Each material branch pipe 13 is provided with a meter 14 and a second raw material control valve 15 to ensure that the material can be accurately conveyed from the material branch pipe 13 to the corresponding chemical treatment device 400 such as a reaction kettle. Taking the configuration of multiple material branch pipes 13 as an example, multiple chemical treatment devices 400 can be correspondingly connected to facilitate the supply of raw materials to the multiple chemical treatment devices 400.

[0045] The degumming device includes a cleaner pipeline 3, a cleaner pump 31, a gas pipeline 2, an evacuation pipeline 4, and at least one gas branch pipe 21 corresponding to the material branch pipe 13 one by one.

[0046] One end of the gas pipeline 2 is connected to the gas supply source 200; one end of the evacuation pipeline 4 is connected to the gas pipeline 2, and the other end is connected to the material pipeline 1; an evacuation control valve 41 is arranged on the evacuation pipeline; one end of the cleaning agent pipeline 3 is connected to the output end of the cleaning agent pump 31 through a first cleaning control valve 32; the input end of the cleaning agent pump 31 is connected to the cleaning agent supply source 300; one end of the gas branch pipe 21 is connected to the gas pipeline 2, and the other end is connected to the pipe section of the material branch pipe 13 between the meter 14 and the second raw material control valve 15; a second cleaning control valve 22 is arranged on the gas branch pipe 21. The gas supplied by the gas supply source 200 enters the material pipeline 1 through the evacuation control valve 41 and the evacuation pipeline 4, and can evacuate the material pipeline 1; after the evacuation treatment, the cleaning agent supplied by the cleaning agent supply source 300 enters the material pipeline 1 through the first cleaning control valve 32 and the cleaning agent pipeline 3 to clean the pipeline, thereby avoiding pipeline blockage, ensuring that the system can operate continuously and stably, reducing production losses caused by failures, and also improving the product yield.

[0047] The feeding and degumming pipeline system designed in this application has a simple structure, few components, free material distribution, low failure rate, and is easy to operate, effectively reducing the expenditure on engineering maintenance.

[0048] The above is the first embodiment of a feeding and degumming pipeline system provided by this application. The following is the second embodiment of a feeding and degumming pipeline system provided by this application. For details, please refer to Figure 1 。

[0049] Based on the solution of the above first embodiment:

[0050] Furthermore, a pressure sensor 7 for detecting the internal pressure is installed on the material pipeline 1, and the internal pressure of the material pipeline 1 is monitored through the pressure sensor 7 so as to be able to process it in time when an abnormal pressure state occurs in the material pipeline 1.

[0051] Furthermore, it further includes a first recovery pipeline 5; one end of the first recovery pipeline 5 is connected to the other end of the material pipeline 1 through a first recovery control valve 51, and the other end of the first recovery pipeline 5 is connected to the raw material recovery device 500. By setting the first recovery pipeline 5 and the raw material recovery device 500, the raw materials in the material pipeline 1 can be recovered to avoid material waste.

[0052] Furthermore, for the convenience of control, the first recovery control valve 51 is an electric control valve.

[0053] Further, it also includes a second recovery pipeline 6; one end of the second recovery pipeline 6 is connected to the material pipeline 1 through a second recovery control valve 61, and the other end is connected to a cleaning agent recovery device 600. By providing the second recovery pipeline 6 and the cleaning agent recovery device 600, the cleaning agent in the material pipeline 1 can be recovered, avoiding waste of the cleaning agent.

[0054] Further, for convenient control, the second recovery control valve 61 is an electric control valve.

[0055] Further, the degumming device also includes a gas buffer tank 23; one end of the gas pipeline 2 is connected to the output end of the gas buffer tank 23; the input end of the gas buffer tank 23 is connected to a gas supply source 200. The provided gas buffer tank 23 can be used to stabilize the gas pressure.

[0056] Further, for convenient control, the first raw material control valve 12, the second raw material control valve 15, the first cleaning control valve 32, the second cleaning control valve 22, and the evacuation control valve 41 are all electric control valves.

[0057] Further, to achieve automation, it also includes a control device, which is electrically connected to the feeding device and the degumming device. Specifically, the control device is electrically connected to the raw material pump 11, the first raw material control valve 12, the second raw material control valve 15, the cleaning agent pump 31, the first cleaning control valve 32, the second cleaning control valve 22, the cleaning agent pump 31, the first recovery control valve 51, and the second recovery control valve 61.

[0058] Further, the control device can be a PLC control device. Using the control device for control has a high degree of automation, high safety, reduces the labor intensity of personnel, saves labor costs, and has a higher processing efficiency and more flexible and convenient operation.

[0059] The feeding and degumming pipeline system of this application works as follows:

[0060] 1. Discharging:

[0061] First, stop the raw material pump 11 and at the same time close the first material control valve, the second material control valve, the first cleaning control valve 32, the second cleaning control valve 22, and the second cleaning control valve 22, and then open the first recovery control valve 51. Then open the evacuation control valve 41 to connect the compressed gas to the material pipeline 1, and use the compressed air to press out the raw materials in the material pipeline 1. The control device can set the corresponding discharging time according to the diameter and internal pressure of the material pipeline 1. When the discharging time of the material pipeline 1 arrives, the second cleaning control valve 22 and the second raw material control valve 15 can be opened in sequence to evacuate the materials in the gas branch pipe 21 and the material branch pipe 13 (the control device can also be used to set the time). As for the evacuation times and time of the materials, the optimal parameters can be set according to the characteristics of the materials and the specifications of the pipeline to achieve the best effect, without limitation.

[0062] 2. Inject the cleaning agent:

[0063] After the material is discharged, close the drain control valve 41, the second cleaning control valve 22, and the first recovery control valve 51; then open the cleaning agent pump 31, the first cleaning control valve 32, and the second recovery control valve 61. The cleaning agent is injected into the material pipeline 1 through the cleaning agent pump 31. The injection time can be timed by the control device. After the pipeline is fully filled with the cleaning agent solution, close the second cleaning control valve 22, and then close the first cleaning control valve 32 and the cleaning agent pump 31 when the pressure in the material pipeline reaches the preset value (note that the air in the pipeline needs to be discharged first during the process), ensuring that the cleaning agent solution is in full contact with the residual material in the pipeline to soften it.

[0064] 3. Flush:

[0065] When the softening time is up, open the drain control valve 41 to inject compressed gas into the material pipeline 1 (since the gas volume is large and the pressure requirement is relatively high, a buffer tank needs to be set up to stabilize the pressure). After reaching the set pressure, close the drain control valve 41. At this time, there is pressure in the material pipeline 1; then simultaneously open and close the second recovery control valve 61 in a timed pulse manner, so that the cleaning agent solution in the material pipeline 1 comes and goes, thereby achieving the purpose of scrubbing.

[0066] 4. Cleaning agent recovery:

[0067] After the pressure in the material pipeline 1 returns to normal, it will be difficult to discharge the remaining cleaning agent in the pipeline. At this time, open the drain control valve 41 and the second recovery control valve 61 at the same time to re-pressurize the pipeline, and use the fast air flow in the pipeline to blow out the remaining cleaning agent in the pipeline. After the recovery is completed, close the drain control valve 41 and the second recovery control valve 61, and the cleaning is completed.

[0068] 5. Purge:

[0069] To ensure the cleanliness of the material pipeline 1, the material branch pipe 13, and the gas branch pipe 21 and avoid affecting the quality of product production, open the drain control valve 41 and the corresponding second raw material control valve 15 and the second cleaning control valve 22, and use compressed gas to purge the pipeline. After reaching the purge time, close the corresponding valves.

[0070] The control device can set corresponding operating procedures according to the cleaning process and material characteristics. If the viscosity of the material is relatively high, the above steps 2-5 can be repeated to meet the final use requirements. If harmful gases are volatilized from the characteristics of the raw material or cleaning agent, the exhaust gas can also be transported to the tail gas treatment device for treatment. At the same time, the cleaning agent supply source (cleaning agent storage tank), the cleaning agent recovery device 600 (cleaning agent recovery tank), and the raw material recovery device 500 (raw material recovery tank) can all be equipped with corresponding weight or level monitoring modules to prompt the corresponding personnel to come and handle when the alarm threshold is reached. The recovered cleaning agent can also be filtered or adjusted according to the process for reuse. At the same time, the control device can solidify the overall process flow in the system, and when needed, it can be triggered with one key to achieve the corresponding functions.

[0071] The above provides a detailed introduction to a feeding and degumming pipeline system provided by the present application. For those of ordinary skill in the art, according to the idea of the embodiments of the present application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
