Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment, and in particular to a novel solid-liquid separation device. Background Technology
[0002] Chinese invention patent CN110054385A discloses a rotary drum screen solid-liquid separator. This invention achieves solid-liquid separation through a rotating drum screen, with spiral blades inside. Gravity allows the solids at the screening point to be conveyed along the spiral blades. However, because this device relies on gravity for solid transport, if the drum screen rotates too fast, the centrifugal force on the solids exceeds gravity, causing them to adhere tightly to the inner wall of the drum screen and preventing them from being properly conveyed by the spiral blades. This limits the drum screen's rotation speed, which in turn affects the wastewater separation efficiency. Therefore, providing a solid-liquid separation device with high separation efficiency and the ability to automatically convey solid fertilizers has become an urgent problem to solve. Utility Model Content

[0010] (III) Beneficial Effects The beneficial effects of this utility model are as follows: Using the above technical solution, a sewage pump transports liquid containing solids into a screen bucket. Driven by the drive mechanism, the screen bucket rotates. During rotation, the liquid is subjected to gravity and centrifugal force, separating the liquid portion through the screen on the screen bucket and concentrating it into the filtrate pool below the anti-splash cover. The solid portion rotates along the wall of the screen bucket. When the solids pass the scraper, the angle of the scraper shifts, achieving a forward conveying effect. Finally, the solids are discharged from one end of the screen bucket. In this application, the solids need to remain in contact with the wall of the screen bucket. Therefore, the discharge of the solids can be achieved by increasing the rotation speed of the screen bucket, overcoming the limitation on the rotation speed of the screen bucket in traditional solid-liquid separators in the background art. This provides a solid-liquid separation device with high separation efficiency and the ability to automatically convey solid fertilizer. Attached Figure Description

[0013] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] Please refer to Figures 1 to 4 This utility model provides a novel solid-liquid separation device, including a frame 1, a splash guard 4, a screen barrel 2, a material conveying mechanism 6, and a drive mechanism 3; The splash guard 4 is installed on the frame 1; The screen barrel 2 is disposed inside the anti-splash cover 4 and is rotatable relative to the anti-splash cover 4; The drive mechanism 3 is connected to the screen barrel 2 and is used to drive the screen barrel 2 to rotate; The material conveying mechanism 6 includes a connecting shaft 61, a fixed rod 62, a connecting rod 63, and a scraper 64; The connecting shaft 61 is disposed inside the screen barrel 2, and both ends of the connecting shaft 61 are fixed on the frame 1; The connecting rod 63 is connected to the connecting shaft 61 by a plurality of fixing rods 62; Multiple scrapers 64 are evenly spaced on the connecting rod 63. The scrapers 64 are inclined and closely attached to the inner wall of the screen barrel 2, and a material conveying channel is formed between adjacent scrapers 64. In use, a sewage pump pumps liquid containing solids into the screen barrel 2. Driven by the drive mechanism 3, the screen barrel 2 rotates. During rotation, the liquid is subjected to gravity and centrifugal force. The liquid part is separated by the screen on the screen barrel 2 and collected in the filtrate pool below the anti-splash cover 4, while the solid part rotates along the barrel wall of the screen barrel 2. When the solid part passes the scraper 64, the angle of the scraper 64 is offset to achieve the effect of forward conveying. Finally, the solid part is discharged from one end of the screen barrel 2. In this application, it is necessary for the solid part to remain in contact with the barrel wall of the screen barrel 2. Therefore, the discharge of the solid part can be achieved by increasing the rotation speed of the screen barrel 2. This overcomes the limitation on the rotation speed of the screen barrel 2 in the traditional solid-liquid separator in the background technology, and thus provides a solid-liquid separation device with high separation efficiency and automatic conveying of solid fertilizer.
[0015] In this embodiment, the sieve barrel 2 includes a sieve cylinder 21 and support components disposed at both ends of the sieve cylinder 21; The support assembly includes a support ring 23 and a support rod 22; The support ring 23 is coaxially arranged with the screen cylinder 21. The support ring 23 is connected to the inner wall of the screen cylinder 21 through a plurality of support rods 22. The support ring 23 is mounted on the connecting shaft 61 through bearings, and the support ring 23 and the internal bearings form a bushing structure. In use, the screen cylinder 21 has screen holes on its cylinder wall. By rotating around the connecting shaft 61, the screen cylinder 21 can achieve solid-liquid separation of the sewage inside the screen cylinder 21.
[0016] In this embodiment, the drive mechanism 3 includes a drive motor, a drive wheel, a driven wheel, and a timing belt; The drive motor is connected to the drive wheel; The driving pulley is connected to the driven pulley via a timing belt; The drive wheel is connected to the screen barrel 2; In use, the drive motor drives the screen barrel 2 to rotate through the drive wheel, driven wheel and synchronous belt.
[0017] In this embodiment, an air knife 5 is also included. The air knife 5 is installed on the inner wall of the anti-splash cover 4. The air outlet of the air knife 5 faces the outer surface of the drum screen and extends along the axial direction of the screen barrel 2. A high-pressure vortex blower is connected to the air knife 5 to provide airflow to the air knife 5. During use, the surface of the screen barrel 2 is cleaned by blowing the air knife 5, thereby reducing the risk of screen clogging.
[0018] In this embodiment, the bottom of the splash guard 4 is provided with a filtrate discharge port.
[0019] In this embodiment, the frame 1 is provided with a recycling tank 7 for collecting solid waste.
[0020] The working principle of this utility model is as follows: The liquid containing solids is pumped into the screen barrel 2 by a sewage pump. Driven by the drive mechanism 3, the screen barrel 2 rotates. During the rotation, the liquid is subjected to gravity and centrifugal force. The liquid part is separated by the screen on the screen barrel 2 and collected into the filtrate pool below the anti-splash cover 4. The solid part rotates along the barrel wall of the screen barrel 2. When the solid part passes the scraper 64, the angle of the scraper 64 is offset to achieve the effect of forward conveying. Finally, the solid part is discharged from one end of the screen barrel 2. In this application, the solid part needs to be kept in contact with the barrel wall of the screen barrel 2. Therefore, the discharge of the solid part can be achieved by increasing the rotation speed of the screen barrel 2. This overcomes the limitation of the rotation speed of the screen barrel 2 in the traditional solid-liquid separator in the background technology, and thus provides a solid-liquid separation device with high separation efficiency and automatic conveying of solid fertilizer.
