Two sludge scrapers 14 are connected, and the cross-section of the two sludge scrapers 14 is a right triangle. The inclined surfaces of the two sludge scrapers 14 are facing the side away from the oil cylinder 2. A baffle 6 is provided at the end of the sludge silo 1 close to the screw conveyor 4. The internal thread of the baffle 6 is connected with a bolt 5. The sludge silo 1 and the baffle 6 are fixed to each other by the bolt 5. A discharge port is provided on the side of the sludge silo 1 close to the screw conveyor 4. A movable cover plate 8 is sleeved on the upper end of the screw conveyor 4, and a sludge discharge port 20 is provided at the lower end of the screw conveyor 4.
[0033] There are two sludge unloading devices, which are symmetrically arranged on the left and right sides of the sludge silo 1.
[0034] The rear side of the screw conveyor 4 is fixedly connected to a first drive motor 9, and the interior of the screw conveyor 4 is rotatably connected to two first rotating shafts 10. The surfaces of the two first rotating shafts 10 are fixedly connected to spiral conveying blades 11. The two first rotating shafts 10 rotate and extend to the outside of the screw conveyor 4. The surfaces of the two first rotating shafts 10 are fixedly connected to first sprockets 12. The surfaces of the two first sprockets 12 are transmission sleeved with first chains 13. The output end of the first drive motor 9 is fixedly connected to the corresponding first rotating shaft 10.
[0035] The two screw conveyors 4 are composed of two sections, an upper section and an lower section, and the upper section and the lower section of the two screw conveyors 4 are connected by bolts 5 .
[0036] The front end of the sludge silo 1 is fixedly connected to a second drive motor 15, and the interior of the sludge silo 1 is rotatably connected to two second rotating shafts 16. The surfaces of the two second rotating shafts 16 are fixedly connected to multiple connecting rods 17. The output end of the second drive motor 15 is fixedly connected to the corresponding second rotating shaft 16. The two second rotating shafts 16 rotate and extend out of the sludge silo 1. The surfaces of the two second rotating shafts 16 are fixedly connected to second sprockets 18, and the surfaces of the two second sprockets 18 are transmission sleeved with second chains 19.
[0037] When using the slide silo, since there are more sludge materials 7 inside the sludge silo 1, the sludge materials 7 inside the sludge silo 1 need to be cleaned. First, the oil cylinder 2 is started to drive the slide 3 to move toward the inside of the sludge silo 1, so that the slide 3 is separated from the baffle 6, and the slide 3 drives the sludge scraper 14 to slide at the bottom of the sludge silo 1. The first drive motor 9 is started to drive the first rotating shaft 10 and the spiral conveying blade 11 to rotate. The first rotating shaft 10 drives the first sprocket 12 to rotate. The first sprocket 12 drives the first chain 13 to rotate. The first chain 13 drives another first sprocket 12, the first rotating shaft 10 and the spiral conveying blade 11 to rotate. Before the sludge material 7 enters the screw conveyor 4, the spiral conveying blade 11 is allowed to idle.
[0038] When the slide 3 slides toward the inside of the sludge silo 1, due to the certain viscosity of the sludge material 7, the sludge material 7 is lifted up by the inclined surface of the sludge scraper 14 and retained in the area surrounded by the sludge scraper 14 and the slide 3. Then, the oil cylinder 2 is started to retract and drive the slide 3 back, so that the sludge material 7 is taken away from the bottom of the sludge silo 1 and pulled into the inside of the screw conveyor 4. The sludge material 7 is transported by the screw conveyor 4, and then the above process is repeated to facilitate the unloading of the sludge material 7 inside the sludge silo 1. Finally, the sludge material 7 is discharged from the sludge discharge port 20 at the bottom of the screw conveyor 4.
[0039] The movable cover plate 8 is arranged above the screw conveyor 4, which is convenient for professionals to observe the wear status of the parts inside the screw conveyor 4 at any time and to facilitate the maintenance of the screw conveyor 4. At the same time, the outer shell of the screw conveyor 4 is composed of two parts and is fixed with bolts 5. When the screw conveyor 4 fails, it is convenient to disassemble and repair the screw conveyor 4. At the same time, the maintenance personnel no longer need the sludge silo 1 to repair the screw conveyor 4, thereby improving the maintenance efficiency.
[0040] After the sludge material 7 inside the sludge silo 1 is discharged to a certain extent, a part of the sludge material 7 adheres to the inner wall of the sludge silo 1, and a bridging phenomenon occurs, making the bottom of the sludge silo 1 hollow. At this time, the second drive motor 15 is started to drive the second rotating shaft 16 and the connecting rod 17 to rotate, and the second rotating shaft 16 drives the second sprocket 18 and the second chain 19 to rotate, and then drives another second rotating shaft 16 and the connecting rod 17 to rotate, so as to facilitate the stirring of the sludge material 7 inside the sludge silo 1, so that the sludge material 7 inside the sludge silo 1 falls to the bottom of the sludge silo 1, and facilitates the discharge of the sludge material 7 through the slide 3, thereby further improving the discharge efficiency of the sludge material 7.
[0041] When the sludge material 7 inside the sludge silo 1 is discharged, the cylinder 2 retracts and drives the slide 3 and the sludge scraper 14 to move, so that the slide 3 stops flush with the end surface of the baffle 6, and the baffle 6 cooperates with the slide 3 to form a blocking surface, so that the slide 3 blocks and closes the discharge port of the sludge silo 1. After the slide silo stops, the sludge material 7 is enclosed in the sludge silo 1, and at the same time, the screw conveyor 4 delays shutdown to empty the sludge material 7 inside the screw conveyor 4, ensuring that the screw conveyor 4 will not start under load when it is powered on.
[0042] Furthermore, by setting the movable cover 8 and fixing the upper and lower parts of the screw conveyor 4 with bolts 5, if the slide silo needs to be shut down for maintenance, maintenance personnel do not need to enter the interior of the sludge silo 1. They can open the movable cover 8 for maintenance, thereby improving the work efficiency and personal safety of the maintenance personnel. By sliding the slide 3 back and forth inside the sludge silo 1, the sludge material 7 inside the sludge silo 1 is easily discharged into the interior of the screw conveyor 4, and the sludge material 7 is transported through the screw conveyor 4, thereby improving the discharge efficiency of the sludge material 7.
[0043] By cooperating with the slide 3 and the baffle 6, it is convenient to start the screw conveyor 4 before the sludge material 7 is discharged into the screw conveyor 4, which can avoid the screw conveyor 4 from being started under load, causing a sharp increase in the working pressure of the screw conveyor 4 and causing damage to the screw conveyor 4. At the same time, it can delay the shutdown after the sludge material 7 inside the sludge silo 1 is discharged, and the screw conveyor 4 can be started in an idle operation, thereby improving the conveying efficiency of the screw conveyor 4, reducing the burden on the screw conveyor 4 when conveying the sludge material 7, and extending the service life of the screw conveyor 4.
[0044] Working principle: When using the slide silo, since there are more sludge materials 7 inside the sludge silo 1, the sludge materials 7 inside the sludge silo 1 need to be cleaned. First, start the oil cylinder 2 to drive the slide 3 to move toward the inside of the sludge silo 1, so that the slide 3 is separated from the baffle 6, and the slide 3 drives the sludge scraper 14 to slide at the bottom of the sludge silo 1. Start the first drive motor 9 to drive the first rotating shaft 10 and the spiral conveying blade 11 to rotate, the first rotating shaft 10 drives the first sprocket 12 to rotate, the first sprocket 12 drives the first chain 13 to rotate, and the first chain 13 drives another first sprocket 12, the first rotating shaft 10 and the spiral conveying blade 11 to rotate. Let the spiral conveying blade 11 idle before the sludge material 7 enters the screw conveyor 4.
[0045] When the slide 3 slides toward the inside of the sludge silo 1, due to the certain viscosity of the sludge material 7, the sludge material 7 is lifted up by the inclined surface of the sludge scraper 14 and retained in the area surrounded by the sludge scraper 14 and the slide 3. Then, the oil cylinder 2 is started to retract and drive the slide 3 back, so that the sludge material 7 is taken away from the bottom of the sludge silo 1 and pulled into the inside of the screw conveyor 4. The sludge material 7 is transported by the screw conveyor 4, and then the above process is repeated to facilitate the unloading of the sludge material 7 inside the sludge silo 1. Finally, the sludge material 7 is discharged from the sludge discharge port 20 at the bottom of the screw conveyor 4.
[0046] The movable cover plate 8 is arranged above the screw conveyor 4, which is convenient for professionals to observe the wear status of the parts inside the screw conveyor 4 at any time and to facilitate the maintenance of the screw conveyor 4. At the same time, the outer shell of the screw conveyor 4 is composed of two parts and is fixed with bolts 5. When the screw conveyor 4 fails, it is convenient to disassemble and repair the screw conveyor 4. At the same time, the maintenance personnel no longer need the sludge silo 1 to repair the screw conveyor 4, thereby improving the maintenance efficiency.
[0047] After the sludge material 7 inside the sludge silo 1 is discharged to a certain extent, a part of the sludge material 7 adheres to the inner wall of the sludge silo 1, and a bridging phenomenon occurs, making the bottom of the sludge silo 1 hollow. At this time, the second drive motor 15 is started to drive the second rotating shaft 16 and the connecting rod 17 to rotate, and the second rotating shaft 16 drives the second sprocket 18 and the second chain 19 to rotate, and then drives another second rotating shaft 16 and the connecting rod 17 to rotate, so as to facilitate the stirring of the sludge material 7 inside the sludge silo 1, so that the sludge material 7 inside the sludge silo 1 falls to the bottom of the sludge silo 1, and facilitates the discharge of the sludge material 7 through the slide 3, thereby further improving the discharge efficiency of the sludge material 7.
[0048] When the sludge material 7 inside the sludge silo 1 is discharged, the cylinder 2 retracts and drives the slide 3 and the sludge scraper 14 to move, so that the slide 3 stops flush with the end surface of the baffle 6, and the baffle 6 cooperates with the slide 3 to form a blocking surface, so that the slide 3 blocks and closes the discharge port of the sludge silo 1. After the slide silo stops, the sludge material 7 is enclosed in the sludge silo 1, and at the same time, the screw conveyor 4 delays shutdown to empty the sludge material 7 inside the screw conveyor 4, ensuring that the screw conveyor 4 will not start under load when it is powered on.
[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
