The embodiment of the application discloses water conservancy sediment removal device. As shown in fig. 1 and fig. 2, a water conservancy dredging device comprises a support 8, a screw conveyor 1, a dilution mechanism 2, a sludge pump 3, a scattering mechanism 4, a screening mechanism 5, a separation mechanism 6 and a collection mechanism 7 are mounted on the support 8, the sludge pump 3 and the screw conveyor 1 are jointly used for extracting sludge in a river channel, the dilution mechanism 2 is used for extracting water in the river channel and introducing the water into the screw conveyor 1, so that the sludge is diluted, the sludge after being diluted by the dilution mechanism 2 is scattered by the scattering mechanism 4, the screening mechanism 5 is used for screening the scattered sludge to separate impurities from the sludge, the separation mechanism 6 is used for separating water in the sludge, and the collection mechanism 7 is used for collecting impurities, sludge and water respectively.
Screw conveyer 1 is vertical setting, and in screw conveyer 1's lower extreme was the input and was used for inserting the silt in river course, screw conveyer 1's upper end was the output and communicates in mud pump 3's the mud pipe that advances. Under the combined action of the mud pump 3 and the screw conveyer 1, the mud at the river bottom spirally rises from the lower end of the screw conveyer 1 to the upper end of the screw conveyer 1 and is sucked into the mud pump 3.
The diluting mechanism 2 comprises a high-pressure water pump 21 installed on the support 8, a water inlet pipe 22 of the high-pressure water pump 21 is used for being inserted into a river channel, a water outlet pipe 23 of the high-pressure water pump 21 is communicated with the inside of the screw conveyor 1, and the water outlet pipe 23 of the high-pressure water pump 21 and a mud inlet pipe of the mud pump 3 are respectively arranged on the left side and the right side of the output end of the screw conveyor 1. Under the action of the high-pressure water pump 21, water in the river channel enters the upper end of the spiral conveyor 1 through the high-pressure water pump 21, and water sprayed out from the high-pressure water pump 21 at high pressure collides with sludge which spirally rises in the spiral conveyor 1 violently, so that the sludge is diluted and dispersed, the viscosity of the sludge is reduced, and impurities and the sludge are primarily separated; under the combined action of the high-speed water injection in the high-pressure water pump 21, the screw conveying of the screw conveyor 1 and the suction force of the sludge pump 3, the diluted sludge enters the sludge pump 3, so that the sludge pump 3 is not easily blocked by the sludge.
As shown in fig. 2 and 3, the scattering mechanism 4 includes a second motor 41 installed on the support 8, an output shaft of the second motor 41 is coaxially connected with a rotating shaft 42, the rotating shaft 42 and the screen drum 51 are arranged in the same axial direction, a plurality of scattering blades 43 extending into the screen drum 51 are welded on the side wall of the rotating shaft 42 in the circumferential direction, and the scattering blades 43 are located on the motion track of the sludge sprayed from the sludge outlet pipe of the sludge pump 3. The diluted sludge sprayed from the sludge pump 3 into the screen cylinder 51 will move to collide with the scattering blades 43 driven to rotate by the second motor 41, and the rotating scattering blades 43 will make the diluted sludge splash at all times, so that the sludge is further separated from the impurities, and the sludge is more loose.
The screen drum 51 is provided with a plurality of screen holes through which only water and sludge pass, when the scattered sludge falls on the inner wall of the screen drum 51, the sludge and the water pass through the screen holes, and impurities are accumulated in the screen drum 51, so that the separation of the sludge and the impurities is realized.
When the impurities in the screen cylinder 51 are separated from the sludge, the first motor 521 drives the screen cylinder 51 to rotate through the synchronous wheel 522 and the synchronous belt 523, the impurities tend to be located on the inner bottom wall of the screen cylinder 51 due to the self-gravity, so the spiral blade 53 in the screen cylinder 51 pushes the impurities in the screen cylinder 51 to move away from the sludge pump 3, and the impurities are discharged from one end of the screen cylinder 51 away from the sludge pump 3.
The separating mechanism 6 comprises a separating box 61 installed on the support 8, the upper end and the lower end of the separating box 61 are both open, the upper end opening of the separating box 61 is located right below the screen drum 51, and sludge discharged from the screen holes of the screen drum 51 falls into the separating box 61.
As shown in fig. 4 and 5, a screening mesh 63 which is obliquely arranged and overturns on a vertical surface is rotatably connected to the inner side wall of the separation box 61 through a horizontal shaft 62, the screening mesh 63 is connected to the inner side wall of the separation box 61 through a plurality of springs 64, the springs 64 are used for urging the lower end of the screening mesh 63 to abut against the inner side wall of the separation box 61, sludge entering the separation box 61 falls onto the upper surface of the screening mesh 63, water in the sludge passes through the screening mesh 63 and is discharged out of the separation box 61, and the sludge slides down along the upper surface of the screening mesh 63 and is gathered at the lower end of the screening mesh 63.
When more sludge is gathered on the sieve mud net 63, the water filtering speed of the sieve mud net 63 is slowed down, and the pumping speeds of the pump 3 and the high-pressure water pump 21 are kept unchanged, so that the water quantity on the upper surface of the sieve mud net 63 is increased, the pressure borne by the sieve mud net 63 is quickly improved, the spring 64 is deformed, the lower end of the sieve mud net 63 is downwards overturned to be separated from the inner side wall of the separation box 61, so that the sludge and the water on the sieve mud net 63 are discharged from the gap between the lower end of the sieve mud net 63 and the inner side wall of the separation box 61, the sludge on the upper surface of the sieve mud net 63 is timely cleaned, and the separation effect of the sludge and the water is ensured.
Due to the greater density of the sludge, the sludge will generally settle on the upper surface of the screen mesh 63, and the water will be above the sludge, approximating the phenomenon of stratification. When the lower end of the mesh screen 63 is turned downward and separated from the inner side wall of the separation tank 61, most of the material discharged from the gap between the lower end of the mesh screen 63 and the inner side wall of the separation tank 61 is sludge, thereby ensuring the separation effect of sludge and water.
When part of the sludge in the sieve mesh 63 is discharged, the pressure borne by the sieve mesh 63 is reduced, and at this time, the spring 64 tends to return to the natural state and urge the sieve mesh 63 to rotate and return, so that the sieve mesh 63 continues to separate the sludge and the water; meanwhile, since the mesh sieve 63 continuously swings up and down, the sludge of the mesh sieve 63 slides down from the upper surface of the mesh sieve 63.
The lower end of the screening mud net 63 is provided with a water guide plate 65 positioned right below the screening mud net 63, the water guide plate 65 is obliquely arranged, and the high end of the water guide plate 65 is connected to the lower end of the screening mud net 63. When the lower end of the screening mesh 63 abuts against the inner side wall of the separation box 61, water penetrating through the lower end of the screening mesh 63 falls on the upper surface of the water guide plate 65 and slides down along the upper surface of the water guide plate 65 until the water slides down from the lower end of the water guide plate 65, and at the moment, the water guide plate 65 is located on the motion track of sludge sliding down from the upper surface of the screening mesh 63, so that the motion track of water discharged from the bottom of the separation box 61 is staggered with the motion track of sludge discharged from the bottom of the separation box 61, and the sludge and the water can be separately collected.
A magnetic plate 66 is mounted on the lower surface of the water guide plate 65, and a magnet 67 for attracting and fixing the magnetic plate 66 is mounted on the inner side wall of the separation box 61. When the lower end of the screening net 63 rotates downwards to be separated from the inner side wall of the separation box 61, the magnetic board 66 can be rotationally adsorbed on the magnet 67, and the magnet 67 can adsorb and fix the water guide board 65 provided with the magnetic board 66.
Under the suction and supporting action of the magnet 67, the lower end of the sieve 63 is easier to maintain in a state of clearance with the inner side wall of the separation box 61, so the spring 64 can urge the sieve 63 to rotate and reset only if more sludge slides off the upper surface of the sieve 63; when the screening net 63 is rotated and reset, the magnetic plate 66 is separated from the magnet 67, the suction force of the magnet 67 to the magnetic plate 66 is reduced, and therefore the sludge amount required by downward overturning of the screening net 63 is not greatly reduced; therefore, the swing frequency of the screen mesh 63 is reduced, and the amount of sludge once slipped off from the screen mesh 63 is greatly increased, thereby improving the service life of the screen mesh 63 and the cleaning efficiency of the sludge.
The collecting mechanism 7 comprises a sludge box 71, a water collecting box 72 and a sundries box 74 which are placed on the support 8, the sludge box 71 is positioned under the water guide plate 65, the water guide plate 65 is used for preventing water which penetrates through the sludge screen 63 from flowing into the sludge box 71, and sludge which penetrates through a gap between the lower end of the sludge screen 63 and the inner side wall of the separation box 61 falls into the sludge box 71 to be collected.
As shown in fig. 1 and 5, the water collecting box 72 is located right below the separation box 61 and between the water guide plate 65 and the high end of the mud screen 63, and water penetrating through the mud screen 63 and water sliding from the upper surface of the water guide plate 65 fall into the water collecting box 72 to be collected; the water collecting box 72 is communicated with a water return pipe 73, and one end of the water return pipe 73, which is far away from the water collecting box 72, can extend to the upper part of the river channel, so that water in the water collecting box 72 can flow back into the river channel.
As shown in fig. 2 and 3, the guide plate 75 is installed on the bracket 8 in an inclined manner, a high end of the guide plate 75 is located at an end of the screen cylinder 51 far away from the mud pump 3, a low end of the guide plate 75 is located right above the sundries box 74, and sundries discharged from the end of the screen cylinder 51 far away from the mud pump 3 slide down into the sundries box 74 along an upper surface of the guide plate 75 for collection.
The implementation principle of a water conservancy sediment removal device of this application embodiment does: in the dredging process, under the combined action of the sludge pump 3 and the screw conveyor 1, sludge at the river bottom spirally rises from the lower end of the screw conveyor 1 to the upper end of the screw conveyor 1; under the effect of high pressure water pump 21, water in the river course will enter into screw conveyer 1's upper end through high pressure water pump 21 in, from high pressure water pump 21 high pressure spun water will take place violent collision with spiral ascending silt in screw conveyer 1 for silt is diluted and is broken up, has reduced the consistency of silt, and makes debris and silt primary separation.
Under the combined action of the high-speed injection of the water in the high-pressure water pump 21, the spiral conveying of the spiral conveyor 1 and the suction force of the sludge pump 3, the diluted sludge enters the sludge pump 3, so that the sludge pump 3 is not easily blocked by the sludge; the diluted sludge in the sludge pump 3 is discharged into the screen cylinder 51 and collides with the scattering blades 43 driven to rotate by the second motor 41, and the scattered sludge 43 causes the diluted sludge to splash, so that the sludge is further separated from impurities, and the sludge is looser.
The scattered sludge falls onto the inner wall of the screen cylinder 51, the sundries are accumulated in the screen cylinder 51, the first motor 521 drives the screen cylinder 51 to rotate through the synchronizing wheel 522 and the synchronizing belt 523, the sundries tend to be on the inner bottom wall of the screen cylinder 51 due to self gravity, and therefore the spiral blade 53 in the screen cylinder 51 pushes the sundries in the screen cylinder 51 to move away from the mud pump 3, so that the sundries are discharged from one end of the screen cylinder 51 away from the mud pump 3 and slide down into the sundries box 74 through the guide plate 75 to be collected.
The sludge and water will pass through the screen holes and fall onto the upper surface of the screen mesh 63, the water in the sludge will pass through the screen mesh 63 and be discharged into the water collection box 72, the water in the water collection box 72 will flow back into the river channel by flowing back, and the sludge will slide down along the upper surface of the screen mesh 63 and be gathered to the lower end of the screen mesh 63.
When more sludge is gathered on the sieve mud 63, the water filtering speed of the sieve mud 63 is slowed down, and the pumping speed of the pump 3 and the high pressure water pump 21 is kept unchanged, so the water amount on the upper surface of the sieve mud 63 is increased, the pressure borne by the sieve mud 63 is quickly increased, the spring 64 is deformed, the lower end of the sieve mud 63 is turned downwards to be separated from the inner side wall of the separation box 61, and the magnetic plate 66 is rotationally adsorbed on the magnet 67, so that the sludge and the water on the sieve mud 63 are discharged into the sludge box 71 from the gap between the lower end of the sieve mud 63 and the inner side wall of the separation box 61.
When part of the sludge in the sieve mud net 63 is discharged, the pressure borne by the sieve mud net 63 is reduced, at this time, the spring 64 tends to return to the natural state and urge the sieve mud net 63 to rotate and return, the magnetic plate 66 is separated from the magnet 67, the lower end of the sieve mud net 63 again abuts against the inner side wall of the separation box 61, and therefore the sieve mud net 63 continues to separate the sludge and the water; meanwhile, as the sieve mud net 63 continuously swings up and down, the sludge of the sieve mud net 63 is convenient to slide off the upper surface of the sieve mud net 63, and the sludge of the sieve mud net 63 is convenient to gather towards the lower end of the sieve mud net 63.
To sum up, this application has realized collecting respectively of silt and debris to make the hydroenergy in the silt enough flow back in the river course.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
