The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those generally understood by those of ordinary skill in the art to which the present application belongs.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0030] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for clarity, the thickness of the layers and regions is enlarged, and the same reference numerals are used to represent the same devices, so their description will be omitted.

[0031] See also Figure 1 An embodiment of the present invention provides a separator interlocking control system, including: a first separator 1, a second separator 2 and a DCS (Distributed Control System) control device 6.

[0032] Among them, the first separator 1 and the second separator 2 are each provided with a terminal for interlocking wires, and the terminal includes: a first terminal, a second terminal, a third terminal and a fourth terminal. The first terminal is a 24V terminal, and the second terminal is 24V when the third terminal and the fourth terminal are closed. The third terminal and the fourth terminal are normally open terminals.

[0033] The DCS control device 6 includes: a first 24V relay DO1, a second 24V relay DO2, a first separator feedback point DI1, and a second separator feedback point DI2.

[0034] In the interlocked state between the first separator 1 and the second separator 2, when the first separator feedback point DI1 of the DCS control device 6 receives the working state feedback signal of the first separator 1 (the working state feedback signal reflects the current speed change type of the separator, and the speed change type includes speed increase and speed decrease), the DCS control device 6 controls the second 24V relay DO2 to output 24V to the second separator 2, and the second separator 2 receives the signal and starts working. When the second separator feedback point DI2 of the DCS control device 6 receives the working state feedback signal of the second separator 2, the DCS control device 6 controls the first 24V relay DO1 to output 24V to the first separator 1, and the first separator 1 receives the signal and starts working. In the interlocked state, the first separator 1 and the second separator 2 cannot speed up or slow down at the same time, so that the production is stable. When the first separator 1 speeds up, the second separator 2 waits at the feeding speed. When the second separator 2 receives the signal from the DCS control device 6, the second separator 2 starts feeding.

[0035] As an optional embodiment, the separator interlocking control system also includes: a third separator 3, a fourth separator 4 and a fifth separator 5, wherein the first separator 1 and the second separator 2 are used to separate refined fine sugar, the third separator 3 is used to separate refined fine sand or cotton sugar, and the fourth separator 4 and the fifth separator 5 are used to separate cotton sugar.

The DCS control device 6 also includes: a third 24V relay DO3, a fourth 24V relay DO4, a fifth 24V relay DO5, a third separator feedback point DI3, a fourth separator feedback point DI4 and a fifth separator feedback point DI5. The first connection terminal and the second connection terminal of the third separator 3 are connected to the third 24V relay DO3, the first connection terminal and the second connection terminal of the fourth separator 4 are connected to the fourth 24V relay DO4, and the first connection terminal and the second connection terminal of the fifth separator 5 are connected to the fifth 24V relay DO5; the third connection terminal and the fourth connection terminal of the third separator 3 are connected to the third separator feedback point DI3, the third connection terminal and the fourth connection terminal of the fourth separator 4 are connected to the fourth separator feedback point DI4, and the third connection terminal and the fourth connection terminal of the fifth separator 5 are connected to the fifth separator feedback point DI5.

The DCS control device 6 is provided with an interlocking touch screen, and an input button and a cut-off button are provided on the interlocking touch screen corresponding to each interlocking mode. Pressing the input button starts the corresponding interlocking mode, and pressing the cut-off button cancels the corresponding interlocking mode. Figure 2 The first separator 1 is represented by 1#, and so on. The control process of the above interlocking mode is similar to the interlocking control process between the first separator 1 and the second separator 2, and will not be repeated here.

[0038] As can be seen from the above, the present invention sets a DCS control device, connects the first terminal and the second terminal of the separator to the 24V relay of the DCS control device, and the DCS control device controls the 24V relay to output a 24V signal when it is energized, and connects the third terminal and the fourth terminal of the separator to the separator feedback point of the DCS control device. The DCS control device can control the interlocking of any combination of separators through an automatic control program, and the operator can quickly control the interlocking mode through remote control, so the control efficiency is higher, and the situation that the interlocking failure caused by the wrong connection point in the traditional method can be avoided.
