The front side of the vertical block 73 is limited and controlled with the inner wall of the monitoring box 2 through the control member 78, so as to realize the vertical displacement operation of the vertical block 73 in the vertical frame 71.

[0031] By setting the scrubbing unit 6, starting the control cylinder 721 drives the vertical frame 71 to move horizontally, so as to realize the scrubbing operation of the elastic cleaning component 63 on the bottom side of the sheet metal water tank and the sensor mirror surface in the monitoring box 2, improve the cleaning strength and ensure the cleaning degree at the same time.

[0034] Among them, the control cylinder 721 is connected to the external air circuit and can be opened and closed through the personnel operating the control panel.

[0035] Please refer to Figures 5-6 In the embodiment of the present invention, the control member 78 includes: A rolling wheel 781, and the rolling wheel 781 and the vertical block 73 are displaced front and back through a reset member 782 to realize the displacement of the rolling wheel 781. An L-shaped groove 783 is opened on the front inner wall of the sheet metal water tank in the monitoring box 2. When the rolling wheel 781 moves horizontally in the L-shaped groove 783, the top spring 77 is compressed, and the elastic cleaning component 63 on the lower layer plate 62 cleans the bottom surface of the sheet metal water tank in the monitoring box 2 until it moves to the vertical part of the L-shaped groove 783, and the top spring 77 resumes and the vertical block 73 moves upward. An arc block 784, when the rolling wheel 781 contacts the inner side surface of the arc block 784, it rolls and moves along the inner side surface of the arc block 784 to the horizontal part of the L-shaped groove 783, and during the process of moving from the vertical part of the L-shaped groove 783 to the inner side surface of the arc block 784, the elastic cleaning component 63 on the upper layer plate 61 cleans the mirror surface of the liquid level acquisition part 3 in the monitoring box 2.

[0036] Please refer to Figure 12 , in the embodiment of the present invention, the reset member 782 includes a cylindrical seat 7821 installed on the side surface of the vertical block 73, and the rolling wheel 781 is rotatably installed at the end of the support shaft 7822. One end of the support shaft 7822 close to the cylindrical seat 7821 is installed with a pressing plate 7823, and the pressing plate 7823 slides inside the cylindrical seat 7821, and a reset spring 7824 is installed on the opposite side inside the cylindrical seat 7821 and the pressing plate 7823. The reset spring 7824 realizes the forward movement of the rolling wheel 781 through the reset elastic force without being affected by other external forces.

[0037] Please refer to Figure 11 , in the embodiment of the present invention, the elastic cleaning component 63 includes a soft brush 631. A plurality of placement grooves 632 are opened on the surfaces of the upper layer plate 61 and the lower layer plate 62, and the base of the soft brush 631 is adapted to the aperture of the placement groove 632 to realize vertical sliding. A telescopic spring 633 is installed between the base of the soft brush 631 and the opposite side of the placement groove 632. The telescopic spring 633 realizes the movement of the soft brush 631 away from the placement groove 632 through the reset elastic force without being affected by other external forces.

[0038] Please refer to Figure 4 , in the embodiment of the present invention, the drainage part 8 includes an electric proportional valve 81, and the electric proportional valve 81 is installed in the drainage equipment groove of the monitoring box 2.

A water outlet pipe 83 is installed at the water outlet of the electric proportional valve 81 and is communicated with an external storage water tank.

[0039] Among them, the electro-hydraulic proportional valve 81 is electrically connected to an external power supply and can be opened and closed through a personnel control panel. Since the slurry inlet situation of each filter chamber has a certain proportional relationship with its distance from the slurry inlet regardless of whether the filter press is fed from the front end, the rear end, or both ends simultaneously, this relationship will affect the water output per unit time of the filtrate. By adjusting the cross-sectional area of the drainage port with the electro-hydraulic proportional valve 81, the interference caused by the above proportional relationship can be compensated for.

[0040] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] During operation, after the filter press works, the water liquid flows from the filter box 1 of the filter press, and the generated filtrate enters the sheet metal water tank of the monitoring box 2. During the slurry feeding process, the volume of the filtrate flowing out of the pore channels per unit time first rises and then falls, and accordingly, the liquid level in the tank will first rise and then fall. During the process of the liquid level falling, the liquid level information is obtained through the liquid level sensor in the liquid level acquisition unit 3. When the acceleration of the liquid level falling reaches the set threshold value, it is determined that the slurry feeding is over. Similarly, during the pressing and drying processes, the process can also be controlled by judging the acceleration of the liquid level falling. And the health status of the filter cloth, diaphragm, and seal is judged through the pulp turbidity sensor in the turbidity acquisition unit 4, and the turbidity data of each pressing is recorded and saved as the health indication value of the filter cloth. When it reaches the set threshold value, a prompt for timely maintenance is issued. After each pressing is over, the water tank and the surface of the sensor are cleaned before the next round of slurry feeding. The specific operation is as follows: The liquid level acquisition unit 3 is cleaned by the water outlet operation of the flushing nozzle 51. The driving of the reduction motor 53 drives the extension rod 52 to rotate, and the extension rod 52 and the connected flushing nozzle 51 are synchronously rotated by cooperating with the upper transmission wheel 541 and the transmission belt 542 to expand the flushing range. Synchronously, the control cylinder 721 is started to drive the piston rod 722 and the vertical frame 71 to move horizontally. When the rolling wheel 781 moves at the horizontal position of the L-shaped groove 783, at this time, the top spring 77 is compressed, and the elastic cleaning assembly 63 on the lower layer plate 62 cleans the bottom side of the sheet metal water tank in the monitoring box 2, and synchronously the mirror surface of the pulp turbidity sensor is cleaned. Until the rolling wheel 781 moves to the vertical part in the L-shaped groove 783, it pushes the top spring 77 to recover and makes the vertical block 73 move upward. Then, by controlling the contraction of the cylinder 721, the vertical frame 71 moves horizontally. At this time, the elastic cleaning component 63 on the lower layer plate 62 disengages from the contact with the bottom side of the sheet metal water tank in the monitoring box 2, and the elastic cleaning component 63 on the upper layer plate 61 cleans the mirror surface of the liquid level acquisition part 3 in the monitoring box 2. Until the rolling wheel 781 contacts the inner side surface of the arc block 784, it starts to roll and moves along the inner side surface of the arc block 784 to the horizontal part of the L-shaped groove 783 to achieve the next cleaning.
