Description

Technical Field

[0001] This utility model relates to the field of filter press equipment technology, specifically a filter press equipment for tunnel boring machine slag. Background Technology

[0002] The construction of urban subway tunnels generates a large amount of tunnel boring machine (TBM) excavated soil. Due to the high population density and dense buildings in cities, it is difficult to accumulate large quantities around the construction site, resulting in significant limitations and difficulties in on-site storage. To ensure the smooth progress of construction, the excavated soil needs to be transported away promptly. Because TBM construction requires the use of materials such as foam, water, and expanding agents to modify the excavated soil, the soil generated has a high water content, making transportation extremely inconvenient and prone to leakage during transport, polluting municipal roads. Simply drying the excavated soil without any treatment takes a long time to meet the requirements for transport, and the prolonged muddy state occupies a large amount of space, seriously affecting the construction progress.

[0003] Existing shield tunneling slag filter press equipment has a simple structure and lacks a replaceable filter plate device. Most filter plates are fixed devices, which will be damaged after long-term use, making it inconvenient to disassemble, replace, and repair. Moreover, the filter holes will become clogged after long-term use, affecting the normal operation of the filter press. The filter plates of existing filter press equipment are also mostly fixed and cannot be disassembled, which not only makes it inconvenient to clean and replace, but also makes it inconvenient to discharge the filtered slag, affecting work efficiency and bringing certain adverse effects to the use process. Therefore, we propose a shield tunneling slag filter press equipment. Utility Model Content

[0029] Working principle

[0030] First, the output shaft of the drive motor 28 is rotated, which drives the fixed stop 31 at the other end of the reinforcing shaft 29 to rotate automatically. This causes the fixed stop 31 to rotate to the bottom of the through groove 22. After the filter plate body 24 is placed into the through groove 22, the limiting block 27 at the lower end of the filter plate body 24 is fixed to the fixed stop 31. The filter plate body 24 is then fixed in the through groove 22, and the area of ​​the filter plate body 24 is the same as that of the through groove 22. The filter plate body 24 can then cover the through groove 22. After the slag containing liquid is introduced into the filter plate body 24 in the through groove 22, the piston rod of the hydraulic cylinder 4 is pushed out, which drives the lifting seat 6 to press down. After the lifting seat 6 presses down, it drives the filter press plate 11 to press down. After the filter press plate 11 is pressed into the through groove 22, the slag on the filter plate body 24 is automatically filtered. The liquid in the slag is then filtered out and flows out of the through groove 22 through the filter holes 26. After the filter press is completed, the output shaft of the drive motor 28 rotates, which drives the fixed stop 31 to rotate until the fixed stop 31 separates from the limit block 27. Then the filter plate body 24 can be separated from the through groove 22 and fall off, which facilitates the unloading and cleaning of the filter press slag. When the filter press plate 11 needs to be replaced, the embedded positioning block 17 on the upper fixed seat 15 of the unblocking plate 12 is inserted into the positioning groove 14 in the U-shaped seat 10 to quickly position the installation position of the unblocking plate 12. At this time, the slot 16 and the fixing bolt 20 are aligned horizontally. After the handwheel 21 is turned to tighten the bolt 19, the tightening bolt 19 rotates through the mounting nut seat 18 and drives the fixing bolt 20 at the other end to move into the slot 16. After both sets of fixing bolts 20 are fixed and clamped with the slot 16, the unblocking plate 12 is quickly changed and fixed. After the unblocking plate 12 is pressed down, it corresponds to the filter hole 26 in the filter plate body 24 and automatically unblocks the blockage in the filter hole 26.
