[0002] Currently, industries such as municipal engineering, aquaculture, chemical, food, pharmaceutical, metallurgy, ceramics, brewing, and sugar refining generally require pressing and dehydration of materials before bagging. Conventional industrial presses are typically complex in structure and large in size, thus occupying a significant area and making material loading and unloading inconvenient. They are also cumbersome, lacking flexibility, and prone to malfunctions and maintenance, resulting in high costs. Existing filter presses do not effectively handle high-viscosity materials; during the pressing process, the center of the filter cake is difficult to dehydrate, and the cake thickness cannot be too thick. In particular, the first dehydration and the second high-pressure pressing cannot be completed simultaneously, leading to high investment costs, labor-intensive processes, and significant overhead.

Then, the pressing drive mechanism is activated to push the piston to move, and the materials and stirring dividers are layered and pressed together. The filtrate is collected in the water collection ring groove through the center hole of the layered stirring dividers and the telescopic guide rod and the guide grid of the right baffle, and discharged into the backwash water tank through the drain pipe. The filtrate from the first drain hole of the transverse pressing cylinder and the piston guide grid is also discharged into the backwash water tank through the outer shell drain pipe. When the second pressing is completed and unloading is required, the transverse pressing cylinder remains stationary, the piston is retracted, and the telescopic control mechanism is activated to open the telescopic joint, automatically separating the stirring dividers and the materials.

The positioning and clamping mechanism is activated to retract the transverse pressing cylinder, while the pressing drive mechanism is activated to advance the piston and expel all the filter cake from the hopper. During backwashing, the high-pressure water pump drives high-pressure water into the drain pipe and into the transverse pressing cylinder to backwash the filter cloth. At the same time, the telescopic guide rod mechanism rotates and moves axially to repeatedly rinse all the filter cloth.

[0042] How to use the horizontal ultra-high pressure stacked pressing automatic unloading and backwashing integrated machine of the present invention:

[0043] S1. Start the positioning and pressing mechanism 7, push the transverse pressing cylinder 5 to the right and press it tightly on the right baffle 3, forming a sealed pressing space with the transverse pressing cylinder 5.

[0044] S2. Start the pressing drive mechanism 10 to move the piston 8 to the left end of the transverse pressing cylinder 5, so that the space of the material hopper is kept to the maximum.

[0045] S3. Start the multi-stage guide telescopic cylinder / oil cylinder 130 to move the telescopic control rod 131 to the left, driving the multi-stage mixing and dividing plates 16 to be evenly distributed in the material bin. Set the telescopic control rod 131 and the feed screw pump to the same pressure.

[0046] S4. Start the feeding control mechanism 25 to move the feeding control piston rod 24 to the right and open the feeding pipe 26.

[0047] S5. Material is pumped in by a screw pump through feed pipe 26. When the material hopper is full, the screw pump pressure reaches the set value and is maintained for a certain period of time to complete the first pressure filtration.

[0048] S6. Turn off the screw pump.

[0049] S7. Start the feeding control mechanism 25, and the feeding control piston rod 24 moves to the left to close the feeding pipe 26.

[0050] S8. Remove the pressure from the multi-stage guide telescopic cylinder / hydraulic cylinder 130.

[0051] S9. Start the pressing drive mechanism 10 to move the piston slightly to the left, leaving space for adding medicine and stirring.

[0055] S13. After the materials and conditioning agent have been mixed evenly for a certain period of time, turn off the dosing pump, turn off the drive motor 195 and the multi-stage guide telescopic cylinder / hydraulic cylinder 130, so that the telescopic control rod 131 can move freely.

[0056] S14. Start the pressing drive mechanism 10 to apply pressure and push the piston 8 to the right, so that the material and the inner wall of the pressing cylinder, multiple stirring and dividing plates 16, the end face of the piston 8 and the end face of the right baffle 40 squeeze each other to discharge water.

[0057] S15. After being filtered through the filter cloth, the filtrate flows into the backwash water tank 20 through the drain pipe 15.

[0058] S16. When the pressing drive mechanism 10 reaches the specified pressure and holds the pressure for a certain period of time, the transverse pressing cylinder 5 remains stationary. The pressing drive mechanism 10 is then activated to apply pressure in the reverse direction, causing the piston 8 to retract and leaving space for the filter cake to be discharged.

[0059] S17. Start the multi-stage guide telescopic cylinder / oil cylinder 130, move the telescopic control rod 131 to the left to automatically separate the filter cake and the stirring dividing plate 16.

[0062] S20. Start the pressing drive mechanism 10, drive the piston 8 to move to the right, and discharge the remaining filter cake in the transverse pressing cylinder 5.

[0063] The filter cloth backwashing method of the present invention:

[0064] 211. First, start the positioning and pressing mechanism 7 to drive the transverse pressing cylinder 5 to move to the right and press it against the right baffle 3. At this time, the transverse pressing cylinder 5 and the right baffle 3 are sealed to each other.

[0065] 212. Start the feed control cylinder / hydraulic cylinder 23 and close the feed pipe 26. Close the dosing valve and close the dosing pipe 18.

[0066] 213. Start the backwash water pump 21 and pump high-pressure water through the drain pipe 15 to backwash the filter cloth of the transverse pressing cylinder 5, the filter cloth on the end face of the piston 8, the filter cloth on the end face of the right baffle 3, and the filter cloth on the surface of the telescopic control rod 131 using the pressure of the high-pressure pump.

[0067] 214. Start the drive motor 195 and the multi-stage guide telescopic cylinder / oil cylinder 130 to make the telescopic control rod 131 rotate and move axially, and repeatedly rinse the surface filter cloth and other filter cloths of the stirring dividing plate 16.

[0068] 215. Adding detergent to the backwash tank 20 can enhance the washing effect.
