Description

Technical Field

[0001] The present invention relates to the technical field of river dredging, and particularly relates to a river dredging sludge treatment system. Background Art

[0002] River dredging generally refers to the dredging operation of a river, which is a part of water conservancy projects. In this process, special mechanical equipment is used to stir up the silt at the bottom of the riverbed to form a turbid muddy water mixture. Then, a sludge pump is used to suck out these mixtures, and a sludge treatment system is used to carry out subsequent treatment on them. The purpose of this is to prevent the silt from accumulating and blocking the river, and at the same time reduce the negative impact of untreated sludge on the environment. The sludge after proper treatment can also be recycled and reused, thus realizing 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 cannot detect the water content of the dehydrated silt, and it is easy to have water residue, which not only causes waste of water resources, but also increases the subsequent treatment process and is not convenient for direct utilization; therefore, we propose a river dredging sludge treatment system to solve this problem.

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

[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, for the described river dredging sludge treatment system, by starting the conveyor motor to drive the conveyor roller to rotate clockwise, the conveyor roller drives the conveyor belt to operate, thereby conveying the dewatered sludge, and guiding it into the collection box on the left through the inner material guide frame and the outer material guide frame. At the same time, the test power supply is energized. At this time, a circuit is formed among the test power supply, the ammeter, the two detection probes, and the sludge in between. When the moisture content of the sludge is extremely low, the resistance of the sludge is very large, making the current detected by the ammeter extremely small. As the moisture content in the sludge increases, the resistance of the sludge rises exponentially, causing the current detected by the ammeter to increase instantaneously, and transmitting the detection result to the controller. The controller controls the output shafts of the cylinder and the electric push rod to extend. The electric push rod drives the outer material guide frame to move to the right along the inner material guide frame, thereby guiding the sludge with a higher water content into the collection box on the right. At the same time, the cylinder drives the side plate on the right to move to the left, and drives the rotating arm to rotate through the cooperation of the slide rail on the right and the sliding frame. The rotating arm drives the side plate on the left to move to the right through the cooperation of the slide rail on the left and the sliding frame. The two side plates drive the two brake pads to approach each other, making the brake pads abut against the outside of the brake disc, thereby increasing the rotational resistance of the cross shaft, further reducing the rotation speed of the screw auger, and increasing the rotation speeds of the drum and the screw rotor, thereby reducing the feeding rate and enhancing the centrifugal dewatering effect, reducing the water content of the dewatered sludge, facilitating transportation and utilization, and reducing water resource waste;

[0029] 3. In the present invention, for the described river dredging sludge treatment system, the transmission between the third driving pulley and the third driven pulley drives the rotating shaft and the dispersing rod to rotate, thereby dispersing the dewatered sludge to facilitate moisture content detection. At the same time, the two conveyor rollers rotate, driving the two inclined wheels to rotate synchronously. The inclined wheels drive the connecting plate to move back and forth through the abutment of the inclined plane with the abutting wheel and under the action of the return spring. The connecting plate drives the mounting plate and the detection probe to move back and forth, making the detection probe contact the sludge at different positions and realizing detection, thereby enhancing the comprehensiveness of detection;

[0030] 4. In the present invention, for the described river dredging sludge treatment system, through the provided centrifugal separation mechanism and conveyor mechanism, centrifugal dewatering of the sludge and moisture content detection can be achieved, and the centrifugal separation speed and feeding speed can be adjusted according to the moisture content detection result, thereby ensuring the sludge dewatering effect, realizing separate collection of sludge with different water contents, avoiding water resource waste, and facilitating subsequent treatment of the sludge that has not been thoroughly dewatered.

A tripod is fixedly installed at the top of the feed hopper 3. The sludge pump 301 is fixedly installed at the top of the tripod. A bracket is fixedly installed on the left side of the housing 2. The feed hopper 3 is fixedly installed at the top of the bracket.

[0067] In this embodiment, an installation cylinder 907 is fixedly installed at the top of the fixed frame 24. The gear frame 901 is rotatably installed in the installation cylinder 907, so as to realize the rotational positioning of the gear frame 901. 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, during use, the sludge suction pipe 303 is inserted into the river channel sludge, and the sludge pump 301 is started to extract the sludge. Then, the sludge is introduced into the feed hopper 3 through the sludge discharge pipe 302. The driving motor 10 is started to drive the driving bevel gear 906 to rotate. The driving bevel gear 906 drives the gear rack 901 to rotate through the engagement with the driven bevel gear 902, thereby driving the two planetary bevel gears 903 to perform circular motion. The planetary bevel gears 903 transmit the power of the driving motor 10 to the horizontal shaft 27 and the transverse shaft 801 through the engagement 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. The transverse shaft 801 drives the spiral auger 802 to rotate to transport the sludge through the feed pipe 8 into the drum 6. At the same time, the horizontal shaft 27 drives the connecting shaft 13 to rotate through the transmission of the first driving 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 driving 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 reverse 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 drum 6 rotates in the same direction as the spiral rotor 7, thereby generating a centrifugal force to throw the sludge outward to form a solid phase layer, while the moisture stays on the inner side. At the same time, the number of teeth of the third gear 603 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 greater than that of the drum 6. Thus, the solid phase layer is conveyed to the right through the spiral blades 701 on the outer side of the spiral rotor 7 and is thrown out from the solid discharge pipe. Subsequently, the dewatered sludge is discharged through the solid phase outlet and falls onto the conveyor belt 401. The separated water is discharged from the liquid discharge pipe and the liquid phase outlet, thereby realizing the solid-liquid separation of the sludge. When the viscosity of the sludge is relatively high, the rotation resistance of the spiral auger 802 will increase. Therefore, due to the setting of the differential 9, the rotation speed of the spiral auger 802 decreases, the rotation speed of the spiral rotor 7 increases, and the rotation speed of the drum 6 increases accordingly, thereby performing a larger centrifugal separation to avoid blockage inside the drum 6. By starting the conveying motor 42 to drive the conveying roller 402 to rotate clockwise, the conveying roller 402 drives the conveyor belt 401 to operate, thereby conveying the dewatered sludge. The dewatered sludge is introduced into the left collecting box 5 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, a circuit is formed among the test power supply 31, the ammeter 32, the two detection probes 33, and the sludge in between. 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 instantaneously, and the detection result is transmitted to the controller 43.The controller 43 controls the output shafts of the air cylinder 19 and the electric push rod 2802 to extend. The electric push rod 2802 drives the outer material guiding frame 2801 to move rightward along the inner material guiding frame 28, thereby guiding the sludge with more water content into the collection frame 5 on the right. Meanwhile, the air 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 side slide rail 20 and the sliding frame 21. The rotating arm 23 drives the left side plate 16 to move rightward through the cooperation of the left side slide rail 20 and the sliding frame 21. The two side plates 16 drive the two brake pads 17 to approach each other, so that the brake pads 17 abut against the outside of the brake disc 803, thereby increasing the rotational resistance of the horizontal shaft 801, further reducing the rotation speed of the spiral auger 802, and increasing the rotation speeds of the rotating drum 6 and the spiral rotor 7, thereby reducing the feeding rate and improving the centrifugal dehydration effect, thereby reducing the water content of the dehydrated sludge, facilitating transportation and utilization, and reducing the waste of water resources. Through the transmission of the third driving pulley 38 and the third driven pulley 39, the rotating shaft 40 and the dispersing rod 41 are driven to rotate, thereby dispersing the dehydrated sludge to facilitate the detection of the water content. At the same time, the two conveying rollers 402 rotate, driving the two inclined wheels 37 to rotate synchronously. The inclined wheels 37 drive the connecting plate 29 to move back and forth through the abutment of the inclined surface with the abutting wheel 36 and under the action of the return 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 the detection, thereby improving the comprehensiveness of the detection;

[0069] By pulling the pull rod 508, the pull plate 505 and the two inclined plates 507 are driven to move horizontally. The inclined plates 507 drive the square plate 504 and the clamping plate 503 to move downward through the cooperation with the inclined holes, so that the clamping plate 503 disengages from the clamping groove, releasing the fixation of the collection frame 5. Then, the collection frame 5 is moved horizontally, so that the collected sludge can be conveyed or discharged.
