To precisely control dye liquor dosage and optimize dyeing results, flow control devices are often required during the sizing and dyeing process.

[0003] However, the flow control device in the prior art usually uses a pneumatically controlled single proportional valve to control and adjust the flow rate. However, the flow accuracy of the dye solution output by this flow control method cannot meet people's requirements. Utility Model Content

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0025] In one embodiment of the present invention, Figure 1-3As shown, a dual flow control device for slurry and dyeing liquid includes a feed pipe 1, a filter 2, a flow meter 3, a first flow regulating pipe 41, a second flow regulating pipe 42, a proportional valve 5, a calibrated ball valve 6 and a discharge pipe 7; the feed pipe 1 is provided with a feed port 11, the feed pipe 1 is connected to one end of the filter 2, the other end of the filter 2 is connected to one end of the flow meter 3, the other end of the flow meter 3 is respectively connected to one end of the first flow regulating pipe 41 and one end of the second flow regulating pipe 42, one end of the discharge pipe 7 is respectively connected to the other end of the first flow regulating pipe 41 and the other end of the second flow regulating pipe 42, and the other end of the discharge pipe 7 is respectively provided with a discharge port 71; the proportional valve 5 is installed on the first flow regulating pipe 41, the proportional valve 5 is controlled by an electric actuator, and the calibrated ball valve 6 is installed on the second flow regulating pipe 42.In this embodiment, the filter 2, the flow meter 3, the proportional valve 5 and the graduated ball valve 6 are all prior art. When installed, the feed pipe 1 is connected to one end of the filter 2, the other end of the filter 2 is connected to one end of the flow meter 3, the other end of the flow meter 3 is connected to one end of the first flow regulating pipe 41 and one end of the second flow regulating pipe 42 respectively, one end of the discharge pipe 7 is connected to the other end of the first flow regulating pipe 41 and the other end of the second flow regulating pipe 42 respectively, and the first flow regulating pipe 41 is connected to the other end of the second flow regulating pipe 42. The proportional valve 5 is installed on the flow regulating pipe 41, and the proportional valve 5 is controlled by an electric actuator. The graduated ball valve 6 is installed on the second flow regulating pipe 42. When working, it can be selected and adjusted according to production needs. If a large flow of indigo dye solution needs to be produced, the indigo dye solution enters from the feed port 11 of the feed pipe 7, passes through the filter 2 and the flow meter 3 in sequence, and then enters the first flow regulating pipe 41 and the second flow regulating pipe 42 respectively. Then, the graduated ball valve 6 is opened by 80%, and the proportional valve 5 is opened by 20% through the electric actuator. , so that the discharge port 71 of the discharge pipe 7 can flow out the indigo dye with accurate accuracy. If a small flow of indigo dye is required, the scale ball valve 6 is closed and the proportional valve 5 is opened by the electric actuator to ensure the accuracy of the flow. When the proportional valve 5 fails, the scale ball valve 6 can be used to control the flow to ensure the stability and reliability of the work. The present application uses the feed pipe 1, the filter 2, the flow meter 3, the first flow regulating pipe 41, the second flow regulating pipe 42, the proportional valve 5, the scale ball valve 6 and the discharge pipe 7. When a small flow output is required, only the electric actuator control is required. The proportional valve 5 can achieve high-precision flow output, and when the proportional valve 5 fails, the graduated ball valve 6 can be used to replace it to continue production, which is beneficial to improving the working reliability and working stability of the pulp and dye liquid dual flow control device. Furthermore, if large flow output is required, a dual flow control method is adopted to make the proportional valve 5 controlled by the electric actuator adjust the flow accuracy by 20%, and the graduated ball valve 6 adjust the flow accuracy by 80%, thereby achieving high-precision large flow output. Compared with the single proportional valve structure of traditional pneumatic control, this application has a wide range of applicable scenarios and higher flow regulation accuracy.

[0026] like Figure 1As shown, the device further includes a first switch 81, a second switch 82, and a third switch 83; the first switch 81 is installed at the feed port 11 and is used to control the opening and closing of the feed port 11; the second switch 82 is installed at the first flow regulating tube 41 and is used to control the opening and closing of the first gap regulating tube 41; the third switch 83 is installed at the discharge port 71 and is used to control the opening and closing of the discharge port 71. In this embodiment, the first switch 81, the second switch 82, and the third switch 83 are set at corresponding pipeline positions to ensure the working stability and reliability of the slurry, dyeing and dyeing liquid dual flow control device.

[0027] like Figure 1 As shown, the discharge pipe 7 is provided with a flow measuring port 72. In this embodiment, the flow measuring port 72 is provided on the discharge pipe 7 to facilitate measurement of the adjusted indigo dye liquor flow rate for subsequent adjustment. Preferably, the flow measuring port 72 is provided with an on / off switch to control the on / off of the flow measuring port 72.

[0028] like Figure 2 As shown, it also includes a water inlet pipe 91, a first sewage pipe 92, a fourth switch 84 and a fifth switch 85. The water inlet pipe 91 is connected to the feed pipe 1, and the water inlet pipe 91 is installed with the fourth switch 84. The first sewage pipe 92 is respectively connected to the first flow regulating pipe 41, the second flow regulating pipe 42 and the discharge pipe 7, and the first sewage pipe 92 is installed with the fifth switch 85. In this embodiment, the fourth switch 84 is specifically installed at the connection between the water inlet pipe 91 and the feed pipe 91. When clean water needs to be introduced for cleaning, the first switch 81 of the feed pipe 1, the third switch 83 of the discharge pipe 7, and the switch of the flow measuring port 72 are first closed, so that the clean water cannot enter the source of the indigo dye solution from the feed port 11, and cannot be discharged from the discharge port 71 and the flow measuring port 72. The second switch 82, the proportional valve 5, the graduated ball valve 6, the fourth switch 84, and the fifth switch 85 are opened accordingly to allow the clean water to flow. Then, clean water is added to the water inlet pipe 91, and the clean water enters the filter 2 from the feed pipe 7, then flows through the flow meter from the filter 2, and enters the first flow regulating pipe 41 and the second flow regulating pipe 42 after diversion, and is finally discharged from the first sewage pipe 92 in a unified manner, which is clear, convenient and fast.

[0029] like Figure 3As shown, it also includes a first backwash pipe 93, a second sewage pipe 94, a sixth switch 86, a seventh switch 87 and an eighth switch 88; one end of the water inlet pipe 91 is provided with a water inlet 911, and the other end of the water inlet pipe 91 is respectively connected to the feed pipe 1 and one end of the backwash pipe 93, the fourth switch 84 is installed at the connection between the water inlet pipe 91 and the feed pipe 1, the other end of the backwash pipe 93 is connected to the filter 2, and the backwash pipe 93 is installed with the sixth switch 86; the seventh switch 87 is installed between the filter 2 and the flowmeter 87, one end of the second sewage pipe 94 is connected to the feed pipe 1, and the second sewage pipe 94 is installed with the eighth switch 88. In this embodiment, if the filter 2 needs to be repeatedly flushed, first close the first switch 81, the fourth switch 84 and the seventh switch 87, and open the sixth switch 86 and the eighth switch 88, and then introduce clean water into the water inlet pipe. The clean water enters from the water inlet 911, then passes through the backflush pipe 93 into the interior of the filter 2, and is then discharged from the feed pipe 1 and the second drain pipe 94 in turn, thereby improving the flushing quality and flushing efficiency of the filter 2.

[0030] like Figure 3 As shown, there are two feed ports 11 and two first switches 81. In this embodiment, the provision of two feed ports 11 and two first switches 81 can accelerate the delivery efficiency of the indigo dye liquor at high flow rates. If one feed port 11 is damaged, the other feed port 11 is available as a backup, thereby ensuring the operational stability and reliability of the dual flow control device for slurry and dye liquor.
