Description

The river dredging waste removal equipment

Technical field

The utility model relates to a kind of river dredging waste removal equipment, is applicable to the hazardous substancess such as mud on drainage top layer, riverbed are removed, and recovers original state of filter bed, improves the permeance property and the efficiency of producing drinking water of filter bed.

Background technology

The diafiltration intake technology is to utilize sand pebble layer on the natural stream channel as filtration, rivers water is converted into underground river bed water takes out the novel intake technology that ground directly supplies the user.In the diafiltration water intake engineering, along with the operation of work, shale can constantly be deposited in the top layer of water intaking filter bed, directly influences the following of river and oozes, and then reduce the water withdrawal of whole engineering.Simultaneously because the silt depth increase; The inner poisonous and harmful substance of mud can get more and more, be deposited on the bottom, riverbed for a long time after, can ferment, blackout, smelly; Directly influenced the water quality of leakage water, therefore must carry out desilting to natural stream channel and handle as the water intaking filter bed.

Traditional desilting equipment is directly to be placed on dredge pump to aspirate mud on the riverbed, and the big sedimentation basin that mud is transported to the bank is concentrated deposition, solidified.But traditional desilting equipment comes with some shortcomings in the diafiltration water intake engineering is used, and can't satisfy the special requirement of engineering.The one, traditional desilting is placed directly in dredge pump and has not only aspirated the mud material on the riverbed, will directly destroy the structure of water intaking filter bed as most important medium---sandy gravel in the diafiltration water intaking simultaneously, and water intaking water quality is had bigger influence; The 2nd, and since bigger as the riverbed area of water intaking filter bed, mud in uneven thickness, and traditional desilting equipment is a point-like, as far as bigger water intaking filter bed, flexibility ratio is not enough, dredging effect is not good, operating efficiency is too slow.

The utility model content

The purpose of the utility model is to provide a kind of river dredging waste removal equipment, and this equipment can be removed the hazardous substancess such as mud that the filter bed top layer covers on the basis of not disturbance water intaking filter bed sand pebble layer, recover original state of filter bed.

For achieving the above object; The utility model technical scheme is following: a kind of river dredging waste removal equipment; Comprise hull, generator and mixing plant are installed on the deck of said hull, generator is the mixing plant power supply; Mixing plant stirs the hazardous substancess such as mud on filter bed top layer, makes the top layer of its disengaging water intaking filter bed and in water, forms silt slurry; Be fixed with blow-off pipe on the side of hull, blow-off pipe links to each other with proof submersible sand discharging pump, and generator is the proof submersible sand discharging pump power supply, and proof submersible sand discharging pump extracts the silt slurry that forms in the water, and through blow-off pipe hazardous substancess such as mud is transported to downstream.

The remarkable result of the utility model is: change traditional desilting mode, adopt mixing plant that the hazardous substancess such as mud on filter bed top layer are stirred, avoided the destruction of direct suction to riverbed filtering layer-sand pebble layer, guaranteed water intaking water quality; After stir accomplishing, will stir the area, downstream that silt slurry that the back forms is transported to the riverbed with dredge pump again, avoid building construction links such as sedimentation basin, reduce cost, realize that no secondary is transported and the purpose of secondary pollution the filter bed desilting on the bank.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.

Like Fig. 1, shown in 2, a kind of river dredging waste removal equipment comprises hull 1, and therefore hull 1, is the safety of assurance equipment operation for the carrier of other equipment is installed, and the bearing capacity of hull 1 is greater than the summation of other equipment.

Generator 2 and mixing plant are installed on the deck of hull 1; In the present embodiment, generator 2 adopts diesel-driven generator, and diesel-driven generator is mixing plant and proof submersible sand discharging pump 6 power supplies; Therefore, the power of diesel-driven generator is greater than the summation of mixing plant and proof submersible sand discharging pump 6 power demands; Mixing plant comprises air compressor machine 3, high-pressure hydraulic pump 4 and high-voltage tube 5; Air compressor machine 3 links to each other with high-voltage tube 5 with high-pressure hydraulic pump 4; Diesel-driven generator is air compressor machine 3 and high-pressure hydraulic pump 4 power supplies, and when mud a was thin, air compressor machine 3 carried out gaslift through high-voltage tube 5 output compressed air to the hazardous substancess such as mud of mud a; Make the top layer of its disengaging water intaking filter bed and in water, form silt slurry, the solid-to-liquid ratio of silt slurry is 0.2～0.25: 1; When mud a is thicker; High-pressure hydraulic pump 4 cuts the hazardous substancess such as mud of mud a through high-voltage tube 5 output water under high pressures; Make its disengaging filter bed top layer and in water, form silt slurry, avoided the destruction of direct suction, guaranteed water intaking water quality riverbed filtering layer-sand pebble layer b.

Be fixed with blow-off pipe 7 on the side of hull 1; Blow-off pipe 7 links to each other with proof submersible sand discharging pump 6, and generator 2 is proof submersible sand discharging pump 6 power supplies, and proof submersible sand discharging pump 6 extracts the silt slurry that forms in the water; And hazardous substancess such as mud are transported to downstream through blow-off pipe 7; Avoided building construction links such as sedimentation basin, reduced cost, realized the purpose of no secondary transhipment and secondary pollution the filter bed desilting on the bank.

Blow-off pipe stretches into for 7 one sections and connects proof submersible sand discharging pump 6 in the water; Another section is fixed on the floating drum 9; Be fixed on the sewage draining exit of the outlet of the blow-off pipe end on the floating drum 9 as equipment; Proof submersible sand discharging pump 6 extracts the silt slurry in the water and through sewage draining exit silt slurry is transported to downstream, recovers the original state and the permeability of filter bed, and is from upstream to downstream successively and accomplishes the desilting work to whole riverbed.Certainly, in the desilting process of reality, the staff can monitor the silt slurry that sewage draining exit is discharged, and when the silt slurry solid-to-liquid ratio of discharging was higher, the staff can control hull 1 continuation circulation this zone filter bed mud a is handled; When the silt slurry solid-to-liquid ratio of sewage draining exit discharge was hanged down, the staff can control hull 1 and move downstream, and underwater bed is carried out desilting, has improved the efficient and the quality of desilting engineering.
