Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a device for intercepting debris in water inlet of a water plant. Background Art

[0002] Generally, water plants use treatment screens to intercept debris in the water when taking in water. The screens can intercept debris of various shapes in the water. They are special water treatment equipment and can be widely used in urban sewage treatment, in the tap water industry, and at the water inlet of power plants. They can also be used as pre-screening equipment in wastewater treatment processes in the textile, food processing, papermaking, leather and other industries. It is one of the most advanced solid-liquid screening equipment in my country.

[0003] When intercepting debris, some debris tends to stay on the grille, causing blockage, reducing the efficiency of water treatment, and even causing damage to the grille. Some existing devices are equipped with a grille cleaning device to scrape the debris off the grille, but the debris will still stay on one side of the grille, and the cleaned debris cannot be collected and processed centrally. In order to prevent the accumulation of debris, manual salvage is required, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a water plant inlet debris intercepting device, which aims to improve some existing devices. A grille cleaning device is set to scrape the debris off the grille, but the debris will still remain on one side of the grille, and the cleaned debris cannot be collected and processed centrally.

[0006] The present application provides a water plant inlet debris interception device including a debris processing component and an interception component.

[0007] The debris handling component includes a debris box, a placement rack, a water inlet, and a lifting mechanism. The debris box is arranged on the placement rack, and the two ends of the placement rack are fixed in the water inlet. The debris box and the placement rack are hollowed out at the bottom, and the lifting mechanism is arranged on the debris box. The interception component includes a mesh, a scraper, and a cylinder. The mesh is arranged on one side of the debris box, and the two ends of the mesh are fixedly connected to the water inlet. The scraper is arranged on the side of the mesh away from the debris box, and the output end of the cylinder is downwardly connected to the scraper.

[0008] In a preferred technical solution of the utility model, a notch is provided on one side of the glove box close to the mesh grid, an inclined plate is provided on the notch, and a top end of the inclined plate is connected to the mesh grid.

[0009] In a preferred technical solution of the utility model, a hanging ring is provided on the glove box, and two hanging rings are provided at two ends of the glove box.

There are two inclined rods, the top ends of the two inclined rods are rotatably connected, and one end of the rope is fixedly connected to the top end of the inclined rod through a connecting block.

[0011] In a preferred technical solution of the utility model, hooks are provided at the bottom ends of the two inclined rods.

[0012] In a preferred technical solution of the utility model, a gantry is provided on the water inlet, and the cylinder is arranged under the gantry.

[0013] In a preferred technical solution of the utility model, the gantry is provided with a wire pulley, and there are two wire pulleys. The other end of the rope passes through the gantry and is connected to the power device through the two wire pulleys in sequence.

[0014] In a preferred technical solution of the utility model, the height of the mesh is slightly higher than the notch, both ends of the mesh are in contact with the inner wall of the water inlet, and a limiting groove is provided on one side of the mesh close to the scraper.

[0015] In a preferred technical solution of the utility model, a baffle is provided on the side of the scraper away from the mesh, a drainage hole is provided on the baffle, and a limit block matching the limit groove is provided on the side of the scraper close to the mesh.

[0017] Beneficial effects: When water enters, debris is intercepted by the mesh, and the scraper is driven by the cylinder to move upward along the mesh to clean up the debris remaining on the mesh. The limit groove and limit block can keep the scraper close to the mesh, achieving a good cleaning effect. When the scraper moves to the gap of the debris box with the debris, the debris will fall into the debris box. When there are too many debris in the debris box, hang the hook on the hanging ring, start the power device, and the debris box can be raised by winding the rope, which is convenient for centralized cleaning of the debris in the debris box. No manual salvage is required, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
