[0023] The winding rod 17 and the expansion roller 16 are arranged to cooperate with the first pressure frame 5 and the second pressure frame 6 to realize the timed transmission conversion of the screen 4, thereby ensuring that the screen 4 is in the state of maximum filtration efficiency for filtering sodium thiocyanate for a long time, ensuring the continuous production and production efficiency of sodium thiocyanate, and there is no need for the staff to regularly stop the production of sodium thiocyanate to replace the screen 4; the two groups of winding rods 17 are driven by the motor to rotate in opposite directions to complete the conversion of the screen 4 located between the first pressure frame 5 and the second pressure frame 6, so that the screen 4 located between the first pressure frame 5 and the second pressure frame 6 always maintains normal screening work for sodium thiocyanate, and there is no need to stop the production process of sodium thiocyanate during the conversion of the screen 4, thereby completing the continuous production of sodium thiocyanate.
