Description
Technical field
The utility model relates to a kind of dewatering installation.Specifically, be to be used for getting rid of fast the dewatering installation of moisture in the mud stockyard, be particularly useful for the draining of the mud of high-moisture percentage.
Background technology
All know in the environmental improvement industry,, need often desilting to be carried out in the lake and handle for keeping the ecological environment in the lake (like Taihu Lake).And mud viscosity of from the lake, digging out and water content are all higher, can't utilize.Therefore, the mud that from the lake, goes out clearly need carry out could utilizing after draining or the curing.The tradition water discharge method is that mud is deposited in the stockyard, comes nature to get rid of moisture wherein through sedimentation, airing and evaporation.Adopt this method, needed for 3～5 years just can make the moisture content of mud reduce to 90～100%, drainage speed is slow.For improving drainage speed, often need to come sedimentation mud through adding flocculant, like this, again can waste of manpower and material resources.
The utility model content
The problem that the utility model will solve provides the quick dewatering installation in a kind of mud stockyard.Adopt this device, not only can get rid of the moisture in the mud fast, and can save the man power and material.
For addressing the above problem, take following technical scheme:
The quick dewatering installation in mud stockyard of the utility model comprises water pump and the cofferdam that is used to stack mud, is characterized in being evenly equipped with in the cofferdam collecting well, and these collecting wells are erected at the bottom, mud stockyard in the cofferdam.Said collecting well contains skeleton, and the skeleton outside is surrounded by pervious layer.Between adjacent collecting well bottom the reverse osmosis ditch is arranged all, in the reverse osmosis ditch water-permeable pipe is arranged.Said water-permeable pipe is the steel wire webmaster, and its two ends are logical with Neighbor Set well lower ends respectively.There are big stone, handstone, thick straw mat and bamboo mat in the water-permeable pipe top successively according to order from bottom to top, and wherein, the particle diameter of big stone is 13～25mm, and the particle diameter of handstone is 6～15mm.
Wherein, said skeleton is a cage of reinforcement.Said pervious layer be with stratum reticulare, straw bag layer and bamboo mat layer according to from inside to outside fixed order on skeleton and form.Said stratum reticulare is wire gauze or gauze wire cloth.The degree of depth of said reverse osmosis ditch is that 0.8～1.5 meter, width are 1～2 meter.The big stone and the handstone thickness of said water-permeable pipe top are respectively 0.5～1 meter and 0.3～0.5 meter.The cross sectional area of collecting well is 1～20 square metre.
The further improvement project of the utility model is, has at least a collecting well oral area that capping is arranged, and cofferdam one side has vacuum pump, and the import of vacuum pump is communicated with collecting well with cover.
Take such scheme, have the following advantages:
Can be found out that by such scheme owing to be evenly equipped with the collecting well that is erected at bottom, mud stockyard in the cofferdam, said collecting well contains skeleton, the skeleton outside is surrounded by pervious layer.Between adjacent collecting well bottom the reverse osmosis ditch is arranged all, in the reverse osmosis ditch water-permeable pipe is arranged.Said water-permeable pipe two ends are logical with Neighbor Set well lower ends respectively.There are big stone, handstone, thick straw mat and bamboo mat in the water-permeable pipe top successively according to order from bottom to top.The mud that from the lake, digs out is deposited in the cofferdam, and through pervious layer, the moisture in the mud may penetrate in collecting well and the water-permeable pipe.Through water pump, can the water in collecting well and the water-permeable pipe be discharged.When drainage speed significantly reduces; Can select one or several collecting well; And on these collecting wells, seal, utilize vacuum pump that this collecting well with cover is vacuumized, make and form negative pressure in this collecting well; Transmit between water-permeable pipe and collecting well through negative pressure, introduce the water in the mud in the collecting well.When the water level in the collecting well with cover satisfies when drawing water condition, utilize water pump to extract out again and get final product.Through evidence, utilize the utility model, only need can make the moisture content of mud reduce to 90～100% in about 3 months, compared with the conventional method in the background technology, can shorten water discharge time greatly, reduced the floor space of mud.Owing to adopt the utility model not need in mud, to add flocculant, can avoid man power and material's waste again.
