Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a slurry distribution device. Background Technology

[0002] In the mineral processing industry, some stages require dividing a continuous slurry into multiple streams to ensure uniform flow and concentration as it is delivered to the next processing step, thereby improving efficiency and effectiveness. However, because slurries often contain large solid particles and have high viscosity, uneven flow distribution, particle deposition, or equipment blockage can easily occur during distribution, severely impacting the stability and production efficiency of subsequent processes. Therefore, the design of slurry distribution devices is of great importance in mineral processing systems.

[0003] Patent CN218810328U discloses a mineral processing slurry distributor, including a distribution box with a flow guide fixedly connected near the top opening. The slurry distribution grid is composed of U-shaped grooves welded from steel plates connected at intervals. After entering the distribution grid through the flow guide, the slurry flows into the left side of the partition before entering the small grooves of the grid, while the remaining portion flows directly into the right side of the partition through the grid gaps, initially achieving uniform distribution of the slurry. A connecting hole is provided on the surface of the partition between the left and right sides to maintain equal liquid levels in both sides of the partition, allowing for further uniform distribution of the slurry. The bottom of the distribution box has multiple discharge ports, with guide chutes A and B connected to the front and rear discharge ports at the bottom of the distribution box for a third uniform distribution of the slurry. After entering the distributor, the slurry undergoes three distributions, ensuring sufficient uniformity of the slurry.

[0004] While the existing technology described above achieves a certain degree of uniformity in slurry distribution through a three-stage distribution method, the following problems still exist in practical use: due to the horizontal setting of the slurry distribution grid and its U-shaped trough design, particles are prone to sedimentation or slurry adhesion, leading to blockage and reducing distribution efficiency and uniformity; the connecting holes on the baffle are easily blocked by the accumulation of solid particles, resulting in an imbalance of liquid levels on both sides of the baffle and affecting distribution accuracy; in addition, when processing high-concentration or high-viscosity slurries, the slurry discharge rate at the discharge port and guide chute may decrease, thereby affecting the overall processing capacity. In view of this, we propose a slurry distribution device. Utility Model Content
