Detailed Description
The inventor finds through research in engineering practice that when a shield tunneling machine excavates a tunnel in a stratum containing clay and sand, the discharged dregs contain a large amount of clay blocks, and the particle size of the clay blocks is generally from tens of millimeters to one hundred millimeters, which is far larger than the sieve holes of a coarse sieve. When the prior art process flow shown in fig. 1 is used for slag treatment, clay blocks, sand and mud delivered from the shield machine pass through the pressure relief box and then directly fall on the coarse screen, which can lead to three adverse consequences:
Firstly, clay blocks block the meshes of a screen, and can cause slurry leakage (namely slurry overflows from a screen box of a vibrating screen) when serious, so that the production cannot be normally carried out;
secondly, a large amount of soil components are mixed in the slag soil of the oversize products of the coarse screen, sand and stone materials in the slag soil cannot be recycled as qualified concrete raw materials, and precious sand and stone material resources are wasted;
Thirdly, even if the oversize materials of the coarse screen are discharged as waste dregs, the dregs are difficult to dehydrate due to the influence of clay and clay blocks, so that the water content in the dregs exceeds the standard, the dregs are easy to scatter during discharging and transporting, the road surface and the surrounding environment are polluted, and if a large amount of dregs with the exceeding water content are stacked too high during storage, collapse and even landslide can occur, so that the huge risk of property personnel loss is caused.
In order to overcome the defects of the mud water treatment process, the inventor provides novel mud water separation equipment and a method for adding a clay block dredging sand washer at the upper part of a coarse screen through repeated researches.
As shown in fig. 2, in the novel mud-water separation apparatus according to an embodiment of the present invention, slurry (containing clay, sand, clay, etc.) discharged from a shield machine is firstly introduced into a depressurization tank 204 for depressurization (another depressurization tank 202 is used as a backup facility for a sand washing machine 203 for clay blocks once it has failed), then introduced into the sand washing machine 203 for clay blocks, the sand washing machine 203 for clay blocks mixed therein is fished out for separate discharge, the remaining sand with smaller particle size is introduced into a coarse screen 201 for screening and dewatering through a bottom screen mesh and an upper overflow of the sand washing machine 203, and oversize materials of the coarse screen 201 are materials with particle size of more than 4mm, and are introduced into a slag yard for stacking; the material with the granularity smaller than 4mm enters the A slurry storage tank 2015 and the B slurry storage tank 2014 communicated with the A slurry storage tank 2015 through the screen mesh of the coarse screen 201, and is pumped into the primary cyclone 206 by the No. 1 slurry pump 2013.
The overflow fine particle slurry from the primary cyclone 206 enters the C slurry tank 2012 for secondary separation or returns to the B slurry tank 2014 for recirculation or enters the settling tank 2011; the underflow coarse slurry from the primary cyclone 206 enters the primary dewatering shaker 205. The materials with the oversize materials of 2-4 mm of the primary dewatering vibrating screen 205 are sent to a slag yard for stacking; the material with the granularity smaller than 2mm passes through the screen mesh of the primary dewatering vibration sieve 205 and then enters the B pulp storage tank 2014 for recycling, or enters the C pulp storage tank 2012 through the communicating pipe 207 of the B pulp storage tank 2014 and the C pulp storage tank 2012, and is pumped into the secondary cyclone 209 by the 2# slurry pump 2010. The overflow fine particle slurry from the secondary cyclone 209 enters the settling pond 2011 to be discharged or returned to the C slurry storage tank 2012 for recycling; the underflow slurry of the secondary cyclone 209 enters a secondary dewatering vibrating screen 208; the materials with the oversize materials of 0.074-2 mm of the secondary dewatering vibrating screen 208 are sent to a slag yard for stacking; fine particulate material passing through the screen of the secondary dewatering screen 208 enters the C slurry tank 2012 for recirculation or discharge into the settling tank 2011.
The connection of the above A, B, C three slurry tanks is shown in fig. 3, the slurry tank a 2015 and the slurry tank B2014 are directly connected by the gasket 301, and the gasket 301 with elasticity is sandwiched between the two tanks to prevent slurry leakage; the B stock chest 2014 and the C stock chest 2012 are in communication via the communication pipe 302, and the three stock chest are mounted together and seated on the base 303.
The mud-water separation equipment and the mud-water separation method according to the invention have the advantages that the clay block dredging sand washer 203 is added at the upper part of the coarse screen 201, so that a large amount of clay blocks can be separated before entering the coarse screen, and the defect of the original mud-water treatment process is well overcome. Three advantages are summarized:
Firstly, the problem that clay blocks block a coarse screen mesh is solved, the unsafe hidden production trouble of 'slurry leakage' of a coarse screen is avoided, and the construction efficiency and the safe and stable operation of production are ensured;
Secondly, the clay component in the sand materials on the coarse screen is greatly reduced, and the sand materials are possibly recycled as concrete materials, so that national resources are protected from being wasted;
Thirdly, even if the oversize materials are discharged as waste, the clay blocks are fished out, so that the dehydration performance of the dregs is improved, the moisture content of the dregs is greatly reduced, the environmental pollution caused by scattering in the transportation process is effectively avoided, and the risk of collapse or even landslide during accumulation and storage of the dregs is also effectively avoided.
