[0016] AsFigure 1 As shown in the figure, the embodiment provides a liquid material pipeline conveying and filtering device, which comprises a liquid inlet pipeline 1, a liquid outlet pipeline 2, two filters 3 and 4, two pressure transmitters 5 and 6, and four control valves 7, 8, 9 and 10. The two filters 3 and 4 are connected in parallel. The first pressure transmitter 5 is installed on the liquid inlet pipeline 1. The liquid inlet pipeline 1 is divided into two branches. One branch is connected to the inlet of the first filter 3 through a first liquid inlet branch pipeline 11. The other branch is connected to the inlet of the second filter 4 through a second liquid inlet branch pipeline 12. The first control valve 7 is installed on the first liquid inlet branch pipeline 11. The second control valve 8 is installed on the second liquid inlet branch pipeline 12. The outlet of the first filter 3 is connected to a first liquid outlet branch pipeline 13. The third control valve 9 is installed on the first liquid outlet branch pipeline 13. The outlet of the second filter 4 is connected to a second liquid outlet branch pipeline 14. The fourth control valve 10 is installed on the second liquid outlet branch pipeline 14. The first liquid outlet branch pipeline 13 and the second liquid outlet branch pipeline 14 are simultaneously connected to the liquid outlet pipeline 2. Through the device, the opening and closing of the two filters can be controlled according to the filtering requirements of the liquid material and the pressure conditions of the inlet and outlet pipelines.
[0017] In the embodiment, the device further comprises a liquid inlet tee joint and a liquid outlet tee joint. The outlet of the liquid inlet pipeline 1 is connected to the liquid inlet tee joint and is divided into two branches through the liquid inlet tee joint, which are respectively connected to the first liquid inlet branch pipeline 11 and the second liquid inlet branch pipeline 12. The outlets of the first liquid outlet branch pipeline 13 and the second liquid outlet branch pipeline 14 are simultaneously connected to the liquid outlet tee joint and are combined into one branch through the liquid outlet tee joint, which is connected to the liquid outlet pipeline 2.
[0018] In the embodiment, the four control valves 7, 8, 9 and 10 are all pneumatic ball valves with pneumatic actuators.
[0019] Preferably, the device can further comprise a control unit. In the embodiment, the control unit is a PLC controller. As shown in the figure, the input end of the control unit 15 is electrically connected to the signal output ends of the two pressure transmitters 5 and 6 to obtain the pressure data detected by the two pressure transmitters. The output end of the control unit 15 is electrically connected to the control signal input ends of the four control valves 7, 8, 9 and 10 to control the opening and closing of the four control valves. In this way, the pressure signals on the inlet and outlet pipelines can be collected by the two pressure transmitters and converted into electrical signals, which are then transmitted to the control unit. The control unit calculates the pressure difference data according to the pressure data on the inlet and outlet pipelines, and then controls the switching of different filters or simultaneously opens the two filters according to the calculated pressure difference data. Figure 2
[0020] In different embodiments, the two filters 3 and 4 can be two filters with different filtering performance and filtering flow rate, so that different filters can be switched according to the liquid material to be filtered and the different flow rates.
[0021] Before the device works, the device is installed into the whole working system. When the device works, the filter to be used is selected, at this time, the control valves of the inlet and outlet of the corresponding filter are opened, and the control valves of the inlet and outlet of the other filter are closed, so that one of the filters is connected into the whole working system. When the other filter does not work, the filter can be maintained. According to the need, two filters can be opened at the same time, and the liquid material to be filtered is filtered at the same time, so as to increase the filtering flow. If two filters with different filtering performance and filtering flow are used, the filter to be used can be selected according to the liquid material to be filtered or the size of the flow. If the device is provided with a control unit, the device can be automatically controlled to open one of the filters or open two filters at the same time according to the pressure difference data of the inlet and outlet pipes.
