Description

Technical Field

[0001] The invention relates to the technical field of river channel desilting, and in particular to a river channel desilting sludge treatment system. Background Art

[0002] River desilting usually refers to dredging of rivers as part of water conservancy projects. In this process, specialized machinery is used to stir up the silt at the bottom of the riverbed to form a turbid mixture of mud and water. Then, the mixture is sucked out with a sludge pump and subsequently treated by a sludge treatment system. The purpose of this is to prevent silt accumulation from blocking the river channel, while also reducing the negative impact of untreated sludge on the environment. Properly treated sludge can also be recycled and reused, thus achieving the recycling of resources.

[0003] During the river dredging process, the water in the sludge needs to be separated to facilitate subsequent recycling and utilization. However, the current conventional treatment devices are unable to detect the water content of the dehydrated sludge, which is prone to residual water. This not only causes a waste of water resources, but also increases the subsequent treatment process, making it inconvenient for direct utilization. Therefore, we propose a river dredging sludge treatment system to solve this problem. Summary of the invention

[0026] The beneficial effects of the present invention are:

[0027] 1. In the present invention, a river channel desilting sludge treatment system is described, by inserting a sludge suction pipe into the river channel sludge, and starting the sludge pump to extract the sludge, and then introducing the sludge into the feed hopper through the sludge discharge pipe, and starting the driving motor to drive the active bevel gear to rotate, the active bevel gear drives the gear frame to rotate by meshing with the driven bevel gear, thereby driving the two planetary bevel gears to perform circular motion, the planetary bevel gears transmit the power of the driving motor to the horizontal shaft and the transverse shaft by meshing with the first gear and the second gear, and according to the differential principle, the power of the driving motor will be more distributed to the side with smaller resistance, the transverse shaft drives the spiral auger to rotate to transport the sludge to the inside of the drum through the feed pipe, and at the same time, the horizontal shaft drives the connecting shaft to rotate through the transmission of the first driving pulley and the first driven pulley, the connecting shaft drives the spiral rotor to rotate through the transmission of the second driving pulley and the second driven pulley, the spiral rotor drives the fourth gear to rotate through the connecting shaft, and the fourth gear drives the linkage by meshing with the third gear. The shaft rotates in the opposite direction, and the linkage shaft drives the drum to rotate through the meshing of the second gear and the first gear, and the drum and the spiral rotor have the same direction of rotation, thereby generating centrifugal force to throw the sludge outward to form a solid phase layer, while the water remains on the inner side. At the same time, the number of teeth of the third gear is slightly larger than the number of teeth of the fourth gear, and the number of teeth of the first gear is slightly larger than the number of teeth of the second gear, so that the rotation speed of the spiral rotor is slightly larger than that of the drum, so that the solid phase layer is transported to the right through the spiral blades on the outer side of the spiral rotor and thrown out from the solid outlet pipe, and then the dehydrated sludge is discharged through the solid phase outlet and falls onto the conveyor belt, and the separated water is discharged from the liquid outlet pipe and the liquid phase outlet, thereby realizing the solid-liquid separation of the sludge, and when the viscosity of the sludge is high, the rotation resistance of the spiral auger will increase, so that due to the setting of the differential, the rotation speed of the spiral auger is reduced, the rotation speed of the spiral rotor is increased, and the rotation speed of the drum is increased accordingly, thereby performing a larger degree of centrifugal separation to avoid blockage inside the drum;

[0028] 2. In the present invention, the river channel desilting sludge treatment system starts the conveying motor to drive the conveying roller to rotate clockwise, and the conveying roller drives the conveyor belt to operate, thereby conveying the dehydrated sludge, and introducing it into the collection frame on the left through the inner guide frame and the outer guide frame, and at the same time, the test power supply is energized. At this time, the test power supply, the ammeter, the two detection probes and the sludge in between form a loop. When the moisture content of the sludge is extremely small, the resistance of the sludge is very large, so that the current detected by the ammeter is extremely small. As the moisture content in the sludge increases, the resistance of the sludge increases exponentially, so that the current detected by the ammeter increases instantly, and the detection result is transmitted to the controller, and the controller controls the output shaft of the cylinder and the electric push rod The electric push rod drives the outer guide frame to move rightward along the inner guide frame, thereby guiding the sludge with a higher water content into the collection frame on the right. At the same time, the cylinder drives the right side plate to move leftward, and drives the rotating arm to rotate through the cooperation of the right slide rail and the slide frame. The rotating arm drives the left side plate to move rightward through the cooperation of the left slide rail and the slide frame. The two side plates drive the two brake pads to move closer to each other, so that the brake pads abut against the outside of the brake disc, thereby increasing the rotation resistance of the horizontal axis, thereby reducing the speed of the spiral auger, and increasing the speed of the drum and the spiral rotor, thereby reducing the feed rate and improving the centrifugal dehydration effect, thereby reducing the water content of the dehydrated sludge, so as to facilitate transportation and utilization, and reduce the waste of water resources;

[0029] 3. In the present invention, the river channel silt treatment system drives the rotating shaft and the breaking rod to rotate through the transmission of the third active pulley and the third driven pulley, thereby breaking up the dehydrated sludge to facilitate the detection of water content. At the same time, the two conveying rollers rotate to drive the two inclined wheels to rotate synchronously. The inclined wheels abut against the abutment wheels through the inclined surfaces and drive the connecting plate to move back and forth under the action of the reset spring. The connecting plate drives the mounting plate and the detection probe to move back and forth, so that the detection probe contacts the sludge at different positions and realizes detection, thereby improving the comprehensiveness of the detection;

[0030] 4. In the present invention, the river channel desilting sludge treatment system can realize centrifugal dehydration and water content detection of sludge through the centrifugal separation mechanism and conveying mechanism, and adjust the centrifugal separation speed and feed speed according to the water content detection result, so as to ensure the sludge dehydration effect, and realize the separate collection of sludge with different water contents, avoid the waste of water resources, and facilitate the subsequent treatment of sludge that has not been completely dehydrated.

[0067] In this embodiment, a mounting cylinder 907 is fixedly installed on the top of the fixing frame 24, and the gear frame 901 is rotatably installed in the mounting cylinder 907, thereby realizing the rotational positioning of the gear frame 901, and the first bevel gear 904 and the second bevel gear 905 are both meshed with the two planetary bevel gears 903.

[0068] In this embodiment, when in use, the sludge is extracted by inserting the sludge suction pipe 303 into the river sludge and starting the sludge pump 301 to extract the sludge, and then the sludge is introduced into the feed hopper 3 through the sludge discharge pipe 302, and the driving motor 10 is started to drive the active bevel gear 906 to rotate. The active bevel gear 906 drives the gear frame 901 to rotate by meshing with the driven bevel gear 902, thereby driving the two planetary bevel gears 903 to perform circular motion. The planetary bevel gear 903 transmits the power of the driving motor 10 to the horizontal shaft 27 and the horizontal shaft 801 by meshing with the first gear 601 and the second gear 602. According to the principle of the differential 9, the power of the driving motor 10 will be more distributed to the side with less resistance, and the horizontal shaft 801 drives the spiral auger 802 to rotate. The sludge is transported to the inside of the drum 6 through the feed pipe 8. At the same time, the horizontal shaft 27 drives the connecting shaft 13 to rotate through the transmission of the first active pulley 12 and the first driven pulley 11. The connecting shaft 13 drives the spiral rotor 7 to rotate through the transmission of the second active pulley 14 and the second driven pulley 15. The spiral rotor 7 drives the fourth gear 604 to rotate through the connecting shaft 605. The fourth gear 604 drives the linkage shaft 606 to rotate in the opposite direction through the engagement with the third gear 603. The linkage shaft 606 drives the drum 6 to rotate through the engagement of the second gear 602 and the first gear 601. The rotation direction of the drum 6 and the spiral rotor 7 is the same, so that centrifugal force is generated to throw the sludge outward to form a solid phase layer, while the water remains on the inside. At the same time, the third gear 603 The number of teeth is slightly larger than that of the fourth gear 604, and the number of teeth of the first gear 601 is slightly larger than that of the second gear 602, so that the rotation speed of the spiral rotor 7 is slightly larger than that of the drum 6, so that the solid phase layer is transported to the right by the spiral blades 701 outside the spiral rotor 7 and thrown out from the solid outlet pipe, and then the dehydrated sludge is discharged through the solid phase outlet and falls onto the conveyor belt 401, and the separated water is discharged from the liquid outlet pipe and the liquid phase outlet, so as to realize the solid-liquid separation of the sludge, and when the viscosity of the sludge is high, the rotation resistance of the spiral auger 802 will increase, so that due to the setting of the differential 9, the rotation speed of the spiral auger 802 is reduced, the rotation speed of the spiral rotor 7 is increased, and the rotation speed of the drum 6 is increased accordingly, so as to perform a larger Centrifugal separation is performed to avoid blockage inside the drum 6. The conveying motor 42 is started to drive the conveying roller 402 to rotate clockwise. The conveying roller 402 drives the conveyor belt 401 to operate, thereby conveying the dehydrated sludge and introducing it into the collection frame 5 on the left through the inner guide frame 28 and the outer guide frame 2801. At the same time, the test power supply 31 is energized. At this time, the test power supply 31, the ammeter 32, the two detection probes 33 and the sludge therebetween form a loop. When the moisture content of the sludge is extremely small, the resistance of the sludge is very large, so that the current detected by the ammeter 32 is extremely small. As the moisture content in the sludge increases, the resistance of the sludge increases exponentially, so that the current detected by the ammeter 32 increases instantly, and the detection result is transmitted to the controller 43.The controller 43 controls the extension of the output shaft of the cylinder 19 and the electric push rod 2802. The electric push rod 2802 drives the outer guide frame 2801 to move rightward along the inner guide frame 28, thereby guiding the sludge with a higher water content into the collection frame 5 on the right. At the same time, the cylinder 19 drives the right side plate 16 to move leftward, and drives the rotating arm 23 to rotate through the cooperation of the right slide rail 20 and the slide frame 21. The rotating arm 23 drives the left side plate 16 to move rightward through the cooperation of the left slide rail 20 and the slide frame 21. The two side plates 16 drive the two brake pads 17 to move closer to each other, so that the brake pads 17 abut against the outer side of the brake disc 803, thereby increasing the rotation resistance of the horizontal shaft 801, thereby reducing the rotation speed of the spiral auger 802 and increasing the drum 6 and the spiral rotor 7. The rotation speed is increased, thereby reducing the feed rate and improving the centrifugal dehydration effect, thereby reducing the water content of the dehydrated sludge, so as to facilitate transportation and utilization and reduce the waste of water resources. The third active pulley 38 and the third driven pulley 39 drive the rotating shaft 40 and the breaking rod 41 to rotate, so as to break up the dehydrated sludge, so as to facilitate the detection of water content. At the same time, the two conveying rollers 402 rotate, driving the two inclined wheels 37 to rotate synchronously. The inclined wheel 37 abuts against the abutting wheel 36 through the inclined surface and drives the connecting plate 29 to move back and forth under the action of the reset spring 34. The connecting plate 29 drives the mounting plate 30 and the detection probe 33 to move back and forth, so that the detection probe 33 contacts the sludge at different positions and realizes detection, thereby improving the comprehensiveness of the detection.

[0069] By pulling the pull rod 508, the pulling plate 505 and the two inclined plates 507 are driven to move horizontally. The inclined plate 507 drives the square plate 504 and the card plate 503 to move downward by cooperating with the inclined hole, so that the card plate 503 is disengaged from the card slot, releasing the fixation of the collecting frame 5, and then the collecting frame 5 is moved horizontally, so that the collected sludge can be transported or unloaded.
