[0017] The application provides a mud scraper for a sludge treatment device.

[0018] 1. This sludge scraper for sludge treatment equipment, through the installation of a control mechanism, addresses the issue in conventional equipment where, during scraping, sludge tends to gradually adhere upwards to the central rotating shaft, potentially affecting rotation over time. Therefore, by incorporating a pushing component, the sludge outside the rotating column is scraped downwards. This facilitates the downward movement of sludge from the scraping mechanism and the outer surface of the rotating column.

[0019] 2. This sludge scraper for sludge treatment equipment, through the setting of a scraping mechanism, allows the inclined scrapers on both sides to rotate with the equipment during rotation. With the assistance of sliding components, it facilitates the removal of mud adhering to the outside of the inclined scrapers, allowing for further scraping. This achieves the purpose of facilitating the movement of mud on the water surface.

[0020] 3. This sludge scraper for sludge treatment equipment, through the installation of a sliding component, uses an electric push plate to drive the scraper blades at the bottom downwards. After passing through the fixed frame, the scraper blades gradually contact the mud outside the inclined scraper. During the scraping process, the scraper blades fall into the water, where floating balls on both sides drive the scraper blades upwards, preventing them from affecting deeper water levels and thus the sedimentation effect. This achieves the purpose of easily scraping the mud outside the inclined scraper.

[0021] 4. The sludge scraper used in this sludge treatment equipment, by setting up a sludge-throwing mechanism, pushes the soil outside the rotating column down through the pushing component, and then gradually moves outward through the arc-shaped surrounding plate. The arc-shaped surrounding plate rotates with the rotating column, at which point the soil can be thrown far away and then moves again with the inclined scraper. This achieves the purpose of facilitating the throwing of soil outside the rotating column outward, preventing it from affecting the rotation of the equipment. Attached Figure Description

The device has the advantages that the mud attached to the mud scraping plate and the outer surface of the rotating column can be conveniently treated. When the device is used, the motor in the motor box is started, the motor starts to drive the rotating column 4 to rotate, and then drives the control mechanism 3 outside the rotating column 4 to rotate, at this time, the control mechanism 3 starts to drive the inside pushing assembly 303 and the outside fixed frame 1 to rotate, the fixed frame 1 drives the abutting plate 7 and the adjusting column 8 outside to rotate, and then drives the pulley 9 at the bottom of the adjusting column 8 to move in the annular track.

The device has the advantages that the mud attached to the mud scraping mechanism and the outer surface of the rotating column can be conveniently promoted to move downward. The motor in the motor box is started, the motor drives the rotating column 4 to rotate, and then drives the fixed ring 305 outside the rotating column 4 to rotate, the fixed ring 305 drives the outside curved rod 304 and the support plate 2 to rotate.

[0040] When the servo motor 301 is turned on, the servo motor 301 drives the bottom rotating shaft 302 to rotate, which in turn drives the turntable 3031 at the bottom of the rotating shaft 302 to rotate, performing multiple semi-circular motions.

This design facilitates the scraping of mud outside the inclined scraper blade. After the motor is turned on, the sludge scraping mechanism 5 rotates inside the sedimentation tank following the fixed frame 1. The inclined scraper blade 506 at the bottom scrapes away the mud adhering to the water surface as it rotates.

[0046] When the electric push plate 5071 is activated, the electric push plate 5071 drives the sliding ring 5072 at the bottom to slide downward outside the inclined column 504. The second adjusting column 5073 and the buckle plate 5074 at the bottom of the sliding ring 5072 move downward along with it, and the buckle plate 5074 always slides downward on the surface of the inclined column 504 until the scraper 5075 contacts the mud attached to the outside of the inclined scraper 506 and scrapes the mud into the water.

[0048] The bottom of the arc-shaped surrounding plate 602 is fixedly connected with a fixed ring, the fixed ring is in water, and the outer part of the arc-shaped surrounding plate 602 is fixedly connected with a partition rod 604.

Since the fixed ring is in water, the mud can be prevented from being rolled into the inner part of the arc-shaped surrounding plate 602. In the process of rotation of the arc-shaped surrounding plate 602, the mud is thrown out at a relatively far distance and is continuously moved by the inclined scraper 506 at the bottom of the mud scraping mechanism 5.

[0049] Working principle: when the device is used, the motor in the motor box is turned on, the motor starts to drive the rotating column 4 to rotate, and then drives the fixed ring 305 outside the rotating column 4 to rotate, the fixed ring 305 drives the outer bent rod 304 and the support plate 2 to rotate, and at the same time, the support plate 2 drives the pushing assembly 303 at the bottom and the fixed frame 1 outside to rotate. The fixed frame 1 drives the abutment plate 7 outside and the adjusting column 8 to rotate, and then drives the pulley 9 at the bottom of the adjusting column 8 to move in the annular track. The mud scraping mechanism 5 and the control mechanism 3 are turned on to perform large-range mud scraping work. The mud scraping mechanism 5 rotates in the inner part of the sedimentation tank together with the fixed frame 1, and the inclined scraper 506 at the bottom scrapes the mud attached to the water surface when rotating. The servo motor 301 is turned on, the servo motor 301 drives the rotating shaft 302 at the bottom to rotate, and then drives the rotating disc 3031 at the bottom of the rotating shaft 302 to rotate for multiple semicircular movements.

[0050] Repeatedly open the electric telescopic rod 3034, the electric telescopic rod 3034 drives the bottom clamping post 3035 and the fixed cylinder up and down, and then drives the second connecting plate 3036 and the arc plate 3037 to scrape the rotating column 4 downward, and the soil and impurities attached to the outer surface of the rotating column 4 are scraped downward. The soil pushed down by the pushing assembly 303 falls above the second fixed ring 601, gradually slides from the outside of the arc-shaped fence 602, and gradually falls in the rotation of the arc-shaped fence 602, and the partition rod 604 plays a guiding role. Since the fixed ring is in water, it can prevent soil from being rolled into the inside of the arc-shaped fence 602. And in the process of rotating the arc-shaped fence 602, the soil is thrown away at a long distance, and the inclined scraper 506 at the bottom of the scraping mechanism 5 drives the soil to continue to move.

[0051] After the work is finished, the pushing assembly 303 and the sliding assembly 507 are opened, the electric push plate 5071 is opened, the bottom sliding ring 5072 of the electric push plate 5071 slides downward outside the inclined column 504, the second adjusting column 5073 at the bottom of the sliding ring 5072 and the buckle plate 5074 move downward, and the buckle plate 5074 always slides downward on the surface of the inclined column 504 until the scraping piece 5075 contacts the soil attached to the outside of the inclined scraper 506, and the soil is scraped into water. At this time, the scraping piece 5075 contacts the water surface, the floating balls 5076 are arranged on both sides, the floating balls 5076 drive the scraping piece 5075 to float, and the affected water surface area is reduced.
