Description

Technical Field

[0001] The utility model relates to the technical field of thickener feeding, and more particularly to an anti-blocking device for thickener feeding. Background Art

[0002] Thickeners are primarily used in mining, water treatment, environmental protection, and other fields. They concentrate low-concentration materials to a certain concentration while producing recyclable clarified water. Modern, high-efficiency thickeners primarily promote rapid sedimentation and concentration of materials by adding flocculants. The feed device within the thickener mixes the flocculant and disperses the slurry, and is considered a key technology for thickeners. Due to the diversity of materials used during feeding, the thickener's feed port is prone to clogging. Therefore, an anti-clogging device is required to clear the thickener's feed port.

[0003] In the existing technology, such as the document with publication number CN219744006U, an anti-blocking device for thickener feeding is disclosed. In this document, a lifting mechanism is used to drive a dredging head to move up and down for dredging. However, the dredging head is mainly a round rod structure with spiral blades on its surface. Although it can dredge the inside of the feed hopper to a certain extent, its dredging effect is not good. Therefore, we propose an anti-blocking device for thickener feeding. Utility Model Content

When the cylindrical cam moves up and down, it drives the connecting shaft to move up and down, and the connecting shaft drives the pressure plate to move up and down, so that the material inside the discharge pipe can be squeezed out from the lower port, thereby improving the dredging effect.

[0007] Preferably, the diameter of the pressing plate is smaller than the inner diameter of the discharge pipe. The pressing plate is located above the auger blade, and the auger blade extends into the discharge pipe.

[0008] Preferably, the driving assembly includes a motor and a connecting rod. A fixed shaft is fixedly arranged at the output end of the motor. A connecting plate is fixedly arranged at the bottom of the fixed shaft. An installation groove is formed at the top of the connecting rod, and the connecting plate is slidably connected with the inner wall of the installation groove.

[0009] Preferably, the stirring assembly includes an extension shaft. A connecting sleeve is fixedly arranged on the circumferential outer wall of the extension shaft. A plurality of stirring frames are fixedly arranged on the circumferential outer wall of the connecting sleeve at equal intervals in a ring shape.
