Description

Technical Field

[0001] The invention relates to the technical field of mud scrapers, and in particular to an intelligent mud scraper device. Background Art

[0002] In the early days of industrial development and urban construction, with the large-scale generation of industrial wastewater and urban sewage, how to effectively treat sewage has become an important issue. Sedimentation tanks are widely used as a common sewage treatment facility. During the use of sedimentation tanks, a large amount of sludge will gradually accumulate at the bottom. If it is not cleaned in time, it will affect the normal operation and treatment effect of the sedimentation tank. As a result, people began to develop equipment that can clean the sludge at the bottom of the sedimentation tank, and the sludge scraper came into being. The early sludge scrapers had a relatively simple structure and a relatively single function. After continuous technological improvements and innovations, various types of scrapers with more complete functions have gradually developed, such as center-drive scrapers, peripheral-drive scrapers, etc.

[0003] Traditional scrapers have some obvious limitations. Traditional scrapers often use mechanical transmission, with relatively simple structures and single functions. For example, the operation control is not flexible enough, and the operating parameters cannot be adjusted in real time according to the actual situation. During operation, the scraping may be unstable, resulting in incomplete cleaning of the sludge at the bottom of the sedimentation tank, affecting the subsequent treatment process and treatment effect. Moreover, the resistance of the scraper cannot be intelligently analyzed, which will cause the scraper drive motor to be easily overloaded, thereby increasing maintenance costs.

[0037] The stirring drive mechanism includes a driving bevel gear 1 51 and a driving bevel gear 2 52. The driving bevel gear 1 51 is fixedly mounted on the top of the surface of the scraper and stirring rod 5 and is located at the bottom of the limiting sleeve 3. The driving bevel gear 2 52 is fixedly mounted on the output end of the driving motor 41 and meshes with the driving bevel gear 1 51. The driving bevel gear 2 52 can transmit the driving force of the driving motor 41 to the scraper and stirring rod 5 through the meshing with the driving bevel gear 1 51, so as to facilitate the rotation and scraping operation of the scraper and stirring rod 5.

[0039] The limit frame 21 can fix the gear ring 22, so that the torsion plate 23 forces the speed gear 27 to mesh with the gear ring 22 when rotating with the scraper and stirring rod 5, and transmits the meshing rotational force to the clutch gear 283 meshing therewith, and drives the speed gear 1 25 to rotate through the meshing clutch gear 283, and then drives the sludge stirring drive shaft 24 to rotate through the speed gear 1 25, so as to realize the driving linkage of the driven bevel gear 2 82 at the bottom of the sludge stirring drive shaft 24. When the auger 9 is not needed to be driven, the electric push rod 281 is started to drive the clutch control shaft 26 to move upward through the drive plate 282, and the clutch gear 283 is driven upward to separate from the speed gear 2 27 and the speed gear 1 25 through the retaining ring 284 on the clutch control shaft 26, so that the sludge stirring drive shaft 24 is no longer driven to rotate, thereby causing the auger 9 to lose driving force.

The transmission gear Wheel 1 83 is rotatably mounted on the front side of the scraper blade 6 through an axle pin and is located at the bottom of the driven bevel gear 2 82.

[0041] The sludge stirring drive shaft 24 can change the driving position through the driven bevel gear 2 82 driving the driven bevel gear 1 81, and then the rotation of the driven bevel gear 1 81 drives the transmission gear 1 83 fixed thereto to rotate, and the transmission gear 1 83 drives the transmission gear 2 85 to rotate through the transmission belt 84, and then drives the driven bevel gear 3 861 to rotate through the transmission gear 2 85, and then the driving direction is changed through the engagement of the driven bevel gear 3 861 and the driven bevel gear 4 862, so that the driven bevel gear 4 862 drives the auger 9 to rotate, so that the auger 9 can slowly disintegrate and crush the sludge with greater resistance, and at the same time transport it to the sinking port at the bottom center of the sedimentation tank 1 for easy discharge.

[0042] The intelligent pressure detection mechanism includes a scraper 1 61, a scraper 2 62, a pressure sensor 612 and a detection plate 613. The scraper 1 61 is slidably installed on the side of the scraper 6 away from the scraper stirring rod 5, and the scraper 2 62 is slidably installed on the bottom of the scraper 6. The front sides of the scraper 1 61 and the scraper 2 62 are both provided with a detection groove 611.

The detection plate 613 is movably embedded in the inside of the detection groove 611 and is fixedly installed on the front side of the pressure sensor 612. The right side of the scraper 1 61 and the top of the scraper 2 62 are fixedly installed with a slide bar 63. The scraper 1 61 passes through the scraper 6 and is fixedly installed with a block 64. The slide bar 63 slides with the scraper 6. The surface of the slide bar 63 is sleeved with a spring 65. One end of the spring 65 is fixedly installed on the side of the scraper 6 away from the scraper stirring rod 5, and the other end of the spring 65 is in contact with the scraper 1 61 and the scraper 2 62 respectively.

[0043] Scraper 1 61 and scraper 2 62 can follow the rotation of the scraper blade 6 to scrape the bottom of the sedimentation tank 1. When scraper 1 61 and scraper 2 62 are squeezed by the sludge during the scraping process, the squeezing force can be detected by the detection plate 613 and transmitted to the pressure sensor 612. Then, the resistance during scraping is detected by the pressure sensor 612. When the scraping resistance exceeds the threshold set in the background, the electric push rod 281 is started by the external controller to perform clutch control to drive the auger 9.

[0044] A conductive slip ring 31 is fixedly installed on the top of the limiting sleeve 3, and the two conductive ends of the conductive slip ring 31 are electrically connected to the external power supply and the top of the surface of the scraper and stirring rod 5 respectively. The top of the surface of the scraper and stirring rod 5 is electrically connected to the electric push rod 281 through the conductive slip ring 31, and the scraper and stirring rod 5 is electrically connected to the pressure sensor 612 through the conductive slip ring 31. The bottom of the scraper and stirring rod 5 rotates with the inside of the limiting sleeve 3; the conductive slip ring 31 can keep supplying power to the top of the scraper and stirring rod 5 during rotation, so that the scraper and stirring rod 5 can power and start the electric push rod 281, ensuring normal startup during rotation. At the same time, the pressure sensor 612 is rotationally powered through the conductive slip ring 31 to ensure that the electrical signal can be electrically connected to the external control.

[0045] A stabilizing frame 91 is fixedly installed on the front side of the scraper blade 6 away from the scraper stirring rod 5, and the end of the auger 9 away from the shield 8 is rotatably installed with the stabilizing frame 91; the stabilizing frame 91 can limit the rotation of one end of the auger 9 to ensure that the auger 9 rotates to break up the resistance of the sludge.

[0046] The surface of the scraper and stirring rod 5 is fixedly installed with a reinforcement sleeve 54 located at the bottom of the torsion plate 23 and a stabilizing plate 53 located at the bottom of the reinforcement sleeve 54 from top to bottom, and a fixed steel cable 55 is fixedly installed at one end of the reinforcement sleeve 54 close to the scraper plate 6. The end of the fixed steel cable 55 away from the reinforcement sleeve 54 is fixedly installed at the top of the end of the scraper plate 6 away from the scraper and stirring rod 5. The surface of the sludge stirring drive shaft 24 is respectively rotated with the internal reinforcement sleeve 54 and the stabilizing plate 53. The bottom of the sludge stirring drive shaft 24 passes through the sludge stirring drive shaft 24, the reinforcement sleeve 54, the stabilizing plate 53 and the shield 8 from top to bottom in sequence and extends to the inside of the shield 8.

[0047] The stabilizing plate 53 and the reinforcing sleeve 54 can limit the rotation of the sludge stirring drive shaft 24 to ensure that the sludge stirring drive shaft 24 will not deform or shake during twisting, thereby ensuring driving stability. At the same time, the fixed steel cable 55 can cooperate with the fixing of the reinforcing sleeve 54 to lift and reinforce the scraper plate 6 to prevent the scraper plate 6 from being overloaded at one end away from the scraper stirring rod 5 and affecting the scraping strength.

[0048] A spiral blade 501 is fixedly installed at the bottom of the scraper and stirring rod 5, and crushing blades 502 for crushing mud are symmetrically and longitudinally welded on both sides of the bottom of the scraper and stirring rod 5; the spiral blade 501 and the crushing blade 502 can rotate with the rotation of the scraper and stirring rod 5, and the sludge that sinks to the bottom of the inner wall of the sedimentation tank 1 can be stably discharged.

[0049] Turbidity sensors 12 for detecting the turbidity of clean water are fixedly embedded on both sides of the top of the sedimentation tank 1, and the inside of the sewage pipe 7 is connected with a gate valve for controlling the discharge of sludge. The turbidity sensor 12 can detect whether the clean water overflowing from the top is qualified. When it is detected to be too turbid, the scraping structure needs to be started to discharge the sludge and sewage for re-precipitation. The gate valve is convenient for controlling the effective discharge of sludge and sewage inside the sedimentation tank 1.

[0050] Working principle: The turbidity of clean water is detected by the turbidity sensor 12. When the turbidity is unqualified and sewage needs to be discharged and sludge needs to be cleaned, the gate valve is started for discharge, and at the same time, the driving motor 41 is started to drive the driving bevel gear 1 51 to rotate through the driving bevel gear 2 52, and the sludge scraping stirring rod 5 is driven to rotate through the driving bevel gear 1 51. The sludge scraping stirring rod 5 drives the scraper plate 6 to rotate, and the scraper plate 6 rotates to scrape and remove the sludge inside the sedimentation tank 1 through the scraper plate 1 61 and the scraper plate 2 62;

[0051] When the scraper blade 1 61 and the scraper blade 2 62 are squeezed by the sludge during the scraping process, the squeezing force can be detected by the detection plate 613 and transmitted to the pressure sensor 612, and then the resistance during the scraping can be detected by the pressure sensor 612;

[0052] When the resistance to scraping mud exceeds the threshold set by the background, the external controller starts the electric push rod 281 to perform clutch control to drive the auger 9. At this time, the electric push rod 281 starts to drive the driving plate 282 to move downward, and the clutch control shaft 26 is driven downward by the driving plate 282. The retaining ring 284 on the clutch control shaft 26 drives the clutch gear 283 downward to engage with the speed gear 2 27 and the speed gear 1 25. The limit frame 21 can fix the gear ring 22, which is convenient for the torsion plate 23 to follow the scraping mud stirring. When the mixing rod 5 rotates, the speed change gear 27 is forced to mesh with the gear ring 22, and the meshed rotational force is transmitted to the clutch gear 283 meshed therewith, and the speed change gear 1 25 is driven to rotate through the clutch gear 283 meshed therewith, and the sludge stirring drive shaft 24 is driven to rotate through the speed change gear 1 25, so that the driven bevel gear 2 82 at the bottom of the sludge stirring drive shaft 24 can be driven in linkage, and then the driven bevel gear 2 82 can cooperate with the driven bevel gear 1 81 to switch the driving position through the sludge stirring drive shaft 24;

[0053] Then, the rotation of the driven bevel gear 1 81 drives the transmission gear 1 83 fixed thereto to rotate, and the transmission gear 1 83 drives the transmission gear 2 85 to rotate through the transmission belt 84, and then the transmission gear 2 85 drives the driven bevel gear 3 861 to rotate, and then the driven bevel gear 3 861 and the driven bevel gear 4 862 are meshed to change the driving direction, so that the driven bevel gear 4 862 drives the auger 9 to rotate, so that the auger 9 can slowly disintegrate and crush the sludge with greater resistance, and at the same time transport it to the sinking port at the bottom center of the sedimentation tank 1 for easy discharge;

[0054] When the pressure is detected by the detection plate 613 and becomes smaller than a certain threshold, the electric push rod 281 is started again to drive the clutch control shaft 26 to move upward through the drive plate 282, and the clutch gear 283 is driven upward to separate from the speed gear 2 27 and the speed gear 1 25 through the retaining ring 284 on the clutch control shaft 26, so that the sludge stirring drive shaft 24 is no longer driven to rotate, thereby causing the auger 9 to lose driving force.
