referring to fig. 1 and fig. 5-6, the present embodiment provides a technical solution based on the first embodiment: the cutting mechanism 11 comprises a baffle 111 which is slidably arranged in the installation cavity 14, a magnetic block 112 is fixed on one side of the baffle 111, an iron core 113 is fixed on one side of the installation cavity 14 close to the magnetic block 112, a wire 114 is uniformly wound on the outer surface of the iron core 113, a through hole 115 is formed in the baffle 111 in a penetrating mode, and a second spring 116 is fixed between one side of the baffle 111 far away from the magnetic block 112 and the inner wall of the installation cavity 14. The side wall of the baffle 111 is attached to the mounting cavity 14, and the diameter of the through hole 115 is the same as that of the through groove 15.
The liquid outlet pipe 13 is provided with an electromagnetic valve. A DCS system and a storage battery for supplying power to the lead 114 are installed in the control box 12, two ends of the lead 114 are connected with the anode and the cathode of the storage battery through a programmable switch, and the DCS system is connected with the magnetic flap liquid level meter 8, the feed pump 9, the programmable switch and the electromagnetic valve through signals.
In this embodiment, the cutting mechanism 11 is configured to cut off the 40% concentration NaOH solution in the liquid inlet pipe 10 after the 40% concentration NaOH solution in the metering chamber reaches the specified volume, so as to avoid that the residual 40% concentration NaOH solution in the liquid inlet pipe 10 continues to flow into the metering chamber, resulting in a larger volume of the metered 40% concentration NaOH solution. When the magnetic flap level meter 8 detects that 40% concentration NaOH solution in the metering chamber reaches a specified volume, the DCS system controls the feed pump 9 to stop working, meanwhile, controls the program control switch to switch on the storage battery to be communicated with the lead 114, the lead 114 cooperates with the iron core 113 to form an electromagnet, and the magnetic pole at one end of the electromagnet, which is contacted with the magnetic block 112, is opposite to the magnetic pole at the corresponding end of the magnetic block 112, so that under the repulsive force, the baffle 111 rapidly moves, the baffle 111 directly closes the through groove 15, and the phenomenon that the residual 40% concentration NaOH solution in the feed pipe 10 continuously flows into the metering chamber, so that the metered 40% concentration NaOH solution is more in volume is avoided. When the next metering is needed, the DCS system controls the program control switch to disconnect the communication between the storage battery and the lead 114, the baffle 111 is reset under the action of the second spring 116 and the attractive force of the iron core 113 and the magnetic block 112, the through hole 115 is aligned with the through groove 15, the through groove 15 is conducted again, and in order to avoid 40% concentration NaOH solution from penetrating into the mounting cavity 14, a layer of alkali-resistant corrosion sealing rubber pad can be arranged at the contact position of the baffle 111 and the inner wall of the mounting cavity 14.
And all that is not described in detail in this specification is well known to those skilled in the art.
In the chemical process for converting ammonium thiocyanate into sodium thiocyanate, when a certain amount of 40% concentration NaOH solution is required to be added, the DCS system inputs the volume of the 40% concentration NaOH solution required to be added, then the DCS system controls the feed pump 9 to work, the feed pump 9 pumps the 40% concentration NaOH solution stored in a storage pool of the 40% concentration NaOH solution into a metering chamber, the magnetic flap level meter 8 can monitor the volume of the 40% concentration NaOH solution in real time, when the DCS system detects that the metering volume of the magnetic flap level meter 8 is the same as the preset volume, the DCS system controls the feed pump 9 to stop working, meanwhile, the program-controlled switch is controlled to be communicated with a storage battery and a conducting wire 114, the conducting wire 114 is matched with an iron core 113 to form an electromagnet, and the magnetic pole at the end of the electromagnet, which is contacted with the magnetic block 112, is opposite to the magnetic pole at the corresponding end of the magnetic block 112, so that the baffle 111 moves rapidly under the repulsive force, the baffle 111 directly closes the through groove 15, and the residual 40% concentration NaOH solution in the feed pipe 10 is prevented from continuously flowing into the metering chamber, so that the volume of the metered 40% concentration NaOH solution is more, and the DCS system controls the electromagnetic valve to work, and the electromagnetic valve to feed the 40% concentration NaOH solution into the metering chamber.
