Description

Technical Field

[0001] The utility model relates to the technical field of concentrators, in particular to an efficient concentrator overflow device. Background Art

[0002] During wet mineral processing, concentrates contain significant amounts of water, necessitating dehydration. Concentrators are among the earliest and most widely used solid-liquid separation equipment in my country's mineral processing industry. They rely on gravity to settle solid particles in the liquid to the bottom of the concentrator tank, where they are then removed. Clear overflow water flows out of the overflow trough at the top of the concentrator tank. Field investigations revealed that floating debris often forms on the surface of the concentrator tanks in the mineral processing system. This debris enters the overflow and ultimately enters the mineral processing circulating water, severely impacting the circulating water quality and, consequently, the quality of the concentrate product.

[0003] During the concentration process, the mineral particles suspended in the slurry settle downward due to gravity. In actual production, if the underflow pump is clogged or the feed concentration is too high, the settling effect is poor, which can easily lead to overflow and turbidity. The overflow chute of the concentrator can also become clogged with slurry foam, resulting in uneven overflow and affecting production efficiency and safety. Therefore, it is necessary to improve the existing overflow chute. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-efficiency concentrator overflow trough to solve the problems of uneven overflow effect, loss of slurry foam and the like existing in the prior art.

[0007] The baffle plate, overflow vertical plate and overflow bottom plate are welded to form an overflow trough, which is arranged in the concentrator body along the entire circumferential direction; the overflow trough is connected to the concentrator body through the concentrator tank body;

[0008] The overflow plate is arranged between the travel wheel track and the baffle plate to slow down the overflow velocity of the slurry foam;

[0009] The rack is located at the outermost edge of the concentrator body and forms a traveling wheel track structure with the track to provide power for the concentrator rake frame to travel.

[0010] Preferably, a baffle plate is provided between the overflow vertical plate and the baffle plate, dividing the overflow trough into an inner overflow trough and an outer overflow trough, for separating the clarified liquid from the pulp foam.

[0011] Preferably, the blocking plate includes a buoy, a buoy blocking plate and a fixing clip.

[0012] Preferably, the buoy is a hollow structure, preferably made of plastic, and is used to suspend the blocking plate above the surface of the ore slurry.

[0023] In the prior art, the overflow port aperture of the overflow trough baffle of the concentrator is too large, resulting in a large amount of slurry foam being lost. The overflow device of the utility model forms an overflow trough structure by combining an overflow baffle and a material baffle plate. At the same time, a baffle plate made of a lightweight material is arranged in the overflow trough to divide the overflow trough into an inner and outer overflow troughs, and overflow holes are opened at the bottom of the baffle plate. The baffle plate automatically adjusts its height as the buoyancy of the overflow liquid in the trough changes. Due to the different densities of clarified water and slurry foam, the slurry foam is blocked in the inner overflow trough, and the clarified water flows into the outer overflow trough along the notch at the bottom of the baffle plate, thereby realizing the separation of slurry foam and clarified water.

[0024] like Figure 1 As shown, the utility model discloses a high-efficiency concentrator overflow device, including: a baffle plate 1, an overflow vertical plate 2, an overflow bottom plate 3, a walking wheel track 5, a rack 6 and a concentrator tank body 7. The baffle plate 1, the overflow vertical plate 2 and the overflow bottom plate 3 are welded into an overflow trough, which is arranged in the concentrator body along the entire circumferential direction; the overflow trough is connected to the concentrator body through the concentrator tank body 7, and the overflow vertical plate 2 is arranged between the walking wheel track 5 and the baffle plate 1, which is used to slow down the overflow flow rate of the slurry foam; the walking wheel track 5, the rack 6 and the concentrator body are connected to form a track structure to provide power for the concentrator rake to travel.

[0025] like Figure 2 As shown, a baffle plate 4 is provided between the baffle plate 1 and the overflow vertical plate 2, dividing the overflow trough into an inner overflow trough and an outer overflow trough. When the overflow liquid flows through the baffle plate, the slurry foam is retained in the inner overflow trough, and the clarified water flows from the inner overflow trough to the outer overflow trough.

[0026] like Figure 3 As shown, the baffle plate 4 includes a buoy 41, a buoy baffle plate 42 and a fixed clip 43. In order to make the baffle plate 4 float on the overflow liquid surface, the buoy is made of lightweight material, such as a hollow structure and / or plastic material; the buoy baffle plate 42 is made of lightweight plastic material, a circular structure composed of multiple pieces, and a number of evenly distributed overflow holes 421 are provided at the bottom to ensure uniform overflow of the clarified liquid; the two end joints of the fixed clip 43 are provided with fixing screws 431, which are fixedly connected to the buoy baffle plate 42.

[0027] The operating principle of this utility model is as follows: overflow liquid from the concentrator enters the overflow device and passes through the overflow plate 2. Solid debris in the overflow liquid is forced to remain within the overflow plate 2. The overflow liquid flows from the upper end of the overflow plate 2 into the overflow trough. The slurry foam in the overflow liquid floats on the overflow liquid surface and is retained in the inner overflow trough by the action of the baffle plate 4 suspended on the overflow liquid surface. Clarified water in the overflow liquid can evenly overflow into the outer overflow trough through the overflow holes 421 at the lower end of the baffle plate 4, thus separating the slurry foam from the clarified water. The overflow plate 2 and the baffle plate 1 are bolted to the overflow base plate 3. After wear caused by water impact, they are easy to replace and maintain. The baffle plate 4 floats in the overflow liquid, effectively preventing the slurry foam from flowing out along the lower end of the baffle plate, thus ensuring the clarity and quality of the clarified water.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims.
