After the filter pressing operation is completed, the telescopic end of the hydraulic cylinder 130 drives the push plate 140 to move back. The filter plate unit 200 connected to the push plate 140 moves along with it and drives the adjacent filter plate unit 200 to move through the pulling part, so that the filter plate units 200 that are squeezed and stuck together are separated, making it easier for the filter residue to fall off.

[0104] Lead screw 330, which is connected to drive component 320;

[0105] The purge air box 340 is mounted on the sliding part of the lead screw 330.

[0106] The main function of the reciprocating purging unit 300 is to assist in blowing away and cleaning the filter residue between the filter plate units 200 after the filter press is completed. The support base 310 provides a stable mounting foundation for the entire reciprocating purging unit 300. The drive component 320 provides power for the movement of the lead screw component 330, which in turn drives the purging air box component 340 to reciprocate, enabling the purging air box component 340 to purge the gaps between the filter plate units 200.

[0107] As one implementation method in this embodiment, refer to Figure 5 As shown, the drive unit 320 includes:

[0108] T-type bevel gear steering gear 321, which is installed in the middle of support base 310;

[0110] A right-angle bevel gear steering gear 323 is mounted on both ends of a support base 310;

[0111] The connecting shaft 324 is connected and installed at one end to the T-shaped bevel gear steering gear 321, and at the other end to the right-angle bevel gear steering gear 323 at both ends of the support base 310.

[0112] Among them, the servo motor 322 features high control precision and fast response speed, enabling precise control of the rotation of the T-type bevel gear steering gear 321. Through the transmission of the T-type bevel gear steering gear 321 and the connecting shaft 324, power is transmitted to the right-angle bevel gear steering gear 323, realizing power distribution and steering, ensuring the synchronous movement of the lead screw 330, and ensuring that the blowing air box 340 can smoothly perform reciprocating motion.

[0113] As one implementation method in this embodiment, refer to Figure 5 As shown, the lead screw 330 includes:

[0114] Bearing support 331, bearing support 331 is mounted on support 310;

[0115] The lead screw 332 has both ends mounted on the bearing support seat 331, and one end of the lead screw 332 is connected to the right angle bevel gear steering gear 323;

[0116] Ball nut seat 333 is mounted on lead screw 332.

[0117] As one implementation method in this embodiment, refer to Figure 5-6 As shown, the purge air box 340 includes:

[0118] The upper end of the bellows body 341 is connected to the side of the ball nut seat 333 by screws.

[0119] Filter screen cover 342 is connected and installed at the air inlet at the upper end of the air box body 341;

[0120] High-pressure fan 343 is installed inside the upper part of the air box 341.

[0121] The air box 341 provides installation space for the high-pressure fan 343 and the filter screen 342, and also serves as a guide for airflow. The high-pressure fan 343 generates a powerful airflow to purge the filter residue between the filter plate units 200. The filter screen 342 blocks foreign objects, preventing them from entering the air box and affecting the normal operation of the high-pressure fan. The screw connection makes the installation and disassembly of the air box 341 and the ball nut seat 333 more convenient, facilitating maintenance and repair of the purging air box 340.

[0122] The working principle of this saccharin production concentration filter press:

[0123] During the concentration and filtration process in saccharin production, the saccharin solution is first conveyed to the space between the filter plate units 200 through the conveying pipe head 150. At this time, the filter plate units 200 are initially in a relatively separated state so that the saccharin solution can smoothly enter the space between the filter plates.

[0124] Subsequently, hydraulic cylinder 130 is activated, and its telescopic end extends, pushing push plate 140 towards filter plate unit 200. During the compression process, the filter plate body 210 fits tightly, creating compression pressure on the saccharin solution. The liquid in the saccharin solution flows out through the filter holes of the filter plate body 210, while solid impurities are trapped between the filter plate units 200, achieving the concentration, filtration, and separation of the saccharin solution.

[0125] After the filter press operation is completed, the telescopic end of the hydraulic cylinder 130 retracts, causing the pusher plate 140 to move away from the filter plate unit 200. Under the action of the pulling part, the filter plate units 200 separate from each other, forming a gap. At this time, the reciprocating purging unit 300 is started, and the servo motor 322 starts working, driving the T-shaped bevel gear steering gear 321 to rotate. The T-shaped bevel gear steering gear 321 transmits power to the right-angle bevel gear steering gears 323 at both ends through the connecting shaft 324. The right-angle bevel gear steering gear 323 drives the lead screw 332 to rotate on the bearing support seat 331. The rotation of the lead screw 332 causes the ball nut seat 333 to move linearly back and forth along the lead screw 332, thereby driving the purging air box component 340 mounted on the ball nut seat 333 to move synchronously.

[0126] During the movement of the purging air box 340, the high-pressure fan 343 starts, draws in air from the air inlet, generates a high-pressure airflow, and guides the air box body 341 through the gap between the filter plate units 200 to purge the residual filter residue.

[0127] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
