Description
Technical field
This use is novel to relate to a kind of device that carries out operation by swabbing action, is specifically related to a kind of device of removing sludge underwater.
Background technology
The benthal deposit in places such as rivers and lakes, aquatic farm, aquarium tank, view lake, bathing beach mainly is the sandstone and the organic mud of inanimate matter.There is harm in sandstone hardly to water quality, and the organic matter in the mud is under the condition of long term hypoxia, through hydrolysis, acidifying and other biological chemistry action, can reenter water body, it is smelly to cause organic contamination, water body to turn black, and causes the discomfort of human body, thereby influences the normal use of water body.Therefore, in order to guarantee the quality of water body, must remove the mud at the bottom.
The sweep-out method of water-bed mud has various ways such as physics, chemistry, biology, common physical treatment process is after draining ponding at present, or in the low water time, remove mud with machinery or artificial mode, this method need be interrupted the use of water body, also has shortcomings such as the waste of expense height, length consuming time, water resource is big simultaneously.For solving this technical problem, the multiple device of removing sludge underwater in water has appearred, for example, notice of authorization number discloses a kind of " mud suction conveyer at the bottom of the movable type water " in the utility model patent file of CN 201195853Y, the water jets under high pressure that this device sprays by the high pressure nozzle that is connected with high-pressure hydraulic pump is impacted water-bed mud and is formed mud, again by the suction hose that is connected with suction pump with these draw mud and be transported to and carry out mud-water separation in the mud, then mud is reclaimed and concentrates and handle; The mouth of pipe of described high pressure nozzle and suction hose is located on the silt pumping car, wherein high pressure nozzle is arranged at the both sides of silt pumping car, the mouth of pipe of suction hose is arranged in the silt pumping car, by the water column of high pressure nozzle ejection impact mud that mud forms after a gate enters silt pumping car by the mouth of pipe suction of suction hose and be transported in the separator for mud and water.This device has been realized just can removing the mud at the bottom under the condition that does not drain ponding; but it is because water-bed except that having mud; usually also contain and do not influence the sandstone of water quality particle; when the suction hose in the above-mentioned patent scheme aspirates mud; the a part of sandstone particle that has been dashed in the mud also can be siphoned away in the lump; unnecessary workload when having increased mud-water separation is especially for place the purify waste water water body at the end of sandstone, more apparent its deficiency with manual type.
Summary of the invention
In view of the deficiencies in the prior art, technical problem to be solved in the utility model provides a kind of water-bed silt displacement device that can effectively remove water-bed mud and sandstone is retained in the original place.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of water-bed silt displacement device, comprise suction pump, on the inlet of this suction pump by a suction tube eddy flow separator for mud and water and the suction hood that be connected in series successively, outlet is connected with jet nozzle by gutter, it is characterized in that described suction hood is the cylindrical drum of an internal diameter greater than the suction tube internal diameter, its higher authorities inwardly shrink and dock with suction tube, following is the pump orifice that inwardly shrinks, and the middle part forms the sandstone decanting zone; Described jet nozzle puts in suction hood and extends to the central authorities of described pump orifice.
A kind of water-bed silt displacement device described in the utility model, wherein, the gutter between described suction pump and the jet nozzle is provided with the pressure-control valve of a bypass.The purpose that this pressure-control valve is set is, when the flow of suction pump outlet is excessive, allows a part of water return water body from described bypass behind this pressure-control valve, and the glassware for drinking water that guarantees jet nozzle simultaneously and sprayed has the pressure of setting.
A kind of water-bed silt displacement device described in the utility model wherein, is a tapered transition between the lower surface of described pump orifice and the described sandstone decanting zone.This tapered transition helps guiding the sandstone particle of sedimentation in suction hood to be discharged outside the suction hood.
Operating principle to water-bed silt displacement device of the present utility model is described below:
Water jets under high pressure by the jet nozzle ejection is impacted water-bed mud, mud in the mud and sandstone have been dashed and have been mixed into mud with water, these mud suck in by suction hood under the effect of suction pump, because the pump orifice cross section of suction hood is little, the cross section of sandstone decanting zone, middle part is big, therefore mud speed when pump orifice flows to the sandstone decanting zone reduces, the lifting force that hybrid particles in the mud is subjected to correspondingly reduces, in flow process subsequently, sandstone particle speed under action of gravity that particle diameter and quality are bigger decrescence is zero also down sedimentation, and the less sludge granules of particle diameter and quality then is inhaled in the eddy flow separator for mud and water with water.
A kind of water-bed silt displacement device described in the utility model, wherein, the design principles of suction hood is to guarantee that the sandstone particle can sedimentation in flow process.The mentality of designing of suction hood described in the utility model is as follows: because under the certain prerequisite of the flow of suction pump, the cross-sectional area of suction hood is big more, water velocity is more little, otherwise otherwise; Therefore need only the rational size of Cross section Design one-tenth with the sandstone decanting zone at suction hood middle part, make the flow velocity of water be reduced to a certain value, this moment, current will inevitably be less than the self gravitation of particle to the lifting force of sandstone particle, and this makes the sandstone particle be kept to zero and then down sedimentation gradually at the process medium velocity that rises.
Water-bed silt displacement device of the present utility model compared with prior art has following beneficial effect:
Because the sandstone particle can sedimentation in suction hood, therefore can not be inhaled in the eddy flow separator for mud and water workload when having reduced mud-water separation; In addition, because jet nozzle is arranged at the centre of the pump orifice of suction hood, therefore improved aspiration rates widely to the mud that breaks up.
