DETAILED DESCRIPTION

[0023] The technical solutions of the embodiments of the utility model are explained and described below in combination with the drawings of the embodiments of the utility model. However, the following embodiments are only preferred embodiments of the utility model, and not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] A papermaking chemical additive concentration detection and automatic regulating device is specifically described below in combination with the drawings of the embodiments of the utility model.

[0025] Embodiment 1

[0026] For the convenience of understanding, please refer to Figures 1 to 4 An embodiment of the papermaking chemical additive concentration detection and automatic regulating device provided by the utility model comprises a storage box 1 and a concentration detector 4, and the storage box 1 is internally provided with an automatic regulating mechanism;

[0027] The automatic regulating mechanism comprises a first filling pipe 6, a second filling pipe 7, two electromagnetic valves 16 and two sensors 17, the storage box 1 is internally provided with a first storage tank 8 and a second storage tank 9, the first filling pipe 6 and the second filling pipe 7 are respectively communicated with the first storage tank 8 and the second storage tank 9, a first discharge port 10 is formed in one side of the first storage tank 8, a second discharge port 11 is formed in one side of the second storage tank 9, the first discharge port 10 is located at the top of the second discharge port 11, the two electromagnetic valves 16 are respectively installed in the first discharge port 10 and the second discharge port 11, one of the two sensors 17 is located at the bottom of the first discharge port 10, and the other sensor 17 is located at the top of the second discharge port 11, a flow-through groove 12 is formed in the concentration detector 4, and a feeding port 13 is formed in the top of the flow-through groove 12.

[0028] It should be noted that the first storage tank 8 can be used to store a solution with a dilute concentration of the additive, and the second storage tank 9 can be used to store a solution with an increased concentration of the additive. When the storage box 1 contains the additive, the concentration detector 4 will float according to the concentration of the additive. If the concentration of the additive is too high, the concentration detector 4 will float upwards, and if the concentration of the additive is too low, the concentration detector 4 will descend. A sensor 17 is arranged, and when the concentration of the additive is too high, the concentration detector 4 floats upwards, and the inlet 13 on the side wall of the concentration detector 4 moves upwards. At this time, the sensor 17 at the bottom of the first outlet 10 reacts to make the electromagnetic valve 16 of the first outlet 10 open for a moment and then close. In this process, the solution in the first storage tank 8 flows into the storage box 1 through the inlet 13 and the flow channel 12 and mixes with the additive in the storage box 1. If the concentration detector 4 still floats upwards, the electromagnetic valve 16 in the first outlet 10 will open again until the inlet 13 is located between the first outlet 10 and the second outlet 11. Conversely, if the concentration of the additive is too low, the concentration detector 4 will descend, and the solution in the second storage tank 9 will be repeatedly added to make the inlet 13 located between the first outlet 10 and the second outlet 11. If the inlet 13 is located between the first outlet 10 and the second outlet 11, it means that the concentration of the additive is appropriate, so that the concentration of the additive can be adjusted according to the situation of the additive.

[0029] In some embodiments, as shown in Figure 2 the inlet 13 is located between the bottom of the first outlet 10 and the top of the second outlet 11. The storage box 1 is fixedly installed at the top with a filling pipe 2 connected to the inside of the storage box 1. The concentration detector 4 is located between the first storage tank 8 and the second storage tank 9.

[0030] It should be noted that by arranging the filling pipe 2, the additive to be detected can be added to the inside of the storage box 1.

[0031] In some embodiments, as shown in Figure 2 the bottom of the storage box 1 is fixedly installed with a servo motor 14. The output end of the servo motor 14 is fixedly installed with a stirring piece 15. The stirring piece 15 is located in the inside of the storage box 1. The inside of the storage box 1 is provided with a sliding groove 3. The concentration detector 4 is slidingly connected in the inside of the sliding groove 3.

[0032] It should be noted that by arranging the servo motor 14, the stirring piece 15 can be driven to rotate. By rotating the stirring piece 15, the mixing of the additive in the inside of the storage box 1 can be accelerated. By arranging the sliding groove 3, the moving direction of the concentration detector 4 can be limited so that the concentration detector 4 can only slide up and down.

[0033] Embodiment 2

[0034] In some embodiments, as shown in Figure 1 one side of the storage box 1 is fixedly installed with a controller 5.

[0035] It should be noted that the controller 5 is connected with the electromagnetic valve 16 and the servo motor 14, and the sensor 17 is connected with the controller 5, by setting the controller 5, the opening time of the electromagnetic valve 16 can be adjusted as required, and the rotation speed and rotation time of the servo motor 14 can be adjusted as required, and the use is more flexible.

[0036] The controller 5, the servo motor 14 and the electromagnetic valve 16 in the utility model are well-known parts, and will not be described here.

[0037] Working principle: when using, the additive to be detected is added to the inside of the storage box 1 through the feeding pipe 2, when the storage box 1 contains the additive, the concentration detection meter 4 will float according to the concentration of the additive, when the concentration of the additive is too high, the concentration detection meter 4 will float upwards, the feeding port 13 on the side wall of the concentration detection meter 4 will move upwards, and the sensor 17 at the bottom of the first discharge port 10 will react to open the electromagnetic valve 16 in the first discharge port 10 for an instant and then close, in this process, the solution in the first storage tank 8 will flow into the storage box 1 through the feeding port 13 and the flow-through groove 12 and mix with the additive in the storage box 1, if the concentration detection meter 4 still floats upwards, the electromagnetic valve 16 in the first discharge port 10 will be opened again, until the feeding port 13 is located between the first discharge port 10 and the second discharge port 11, on the contrary, if the concentration of the additive is too low, the concentration detection meter 4 will descend, and the solution in the second storage tank 9 is repeatedly added, so that the feeding port 13 is located between the first discharge port 10 and the second discharge port 11.
