Description

Technical field:

[0001] The utility model relates to the field of lead-zinc ore dressing, in particular to an auxiliary seal for a thickener. Background technology:

[0002] Thickener is a solid-liquid separation equipment based on gravity sedimentation. It is usually a cylindrical shallow tank with a conical bottom made of concrete or metal welded plates as structural materials. The slurry with a solid weight of 10% to 20% can be concentrated into an underflow slurry with a solid content of 45% to 55% by gravity sedimentation. With the help of a slow-running (1 / 3 to 1 / 5 r / min) rake installed in the thickener, the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener. A relatively clean clarified liquid (overflow) is produced on the top of the thickener and discharged from the annular chute at the top.

[0003] The thickener is used to thicken tailings. Due to the addition of sulfuric acid in the beneficiation process, acidic gas will evaporate. Some of the acidic gas will be discharged from the top, but a certain amount of acidic gas will still be discharged from the bottom flow outlet. The bottom flow outlet is connected to a discharge pipe through a sealing flange. These acidic gases will leak along the seals of the two. Long-term leakage, if there is no corresponding sealing operation, will cause the acidic gas to corrode the collector, resulting in damage to the collector. Utility model content:

[0004] The utility model aims to provide an auxiliary seal for a thickener.

[0005] The utility model is implemented by the following technical solutions:

[0006] A thickener auxiliary seal comprises an underflow outlet discharge pipe, a bracket is arranged on one side of the underflow outlet discharge pipe, a straight-tube fan is fixedly installed on one side of the bracket, one end of the bracket is fixedly connected to a mounting frame, a rubber ring is fixedly installed on the top end of the mounting frame, a sealing rubber plate is fixedly connected to the bottom end of the rubber ring, and the sealing rubber plate is sleeved on the underflow outlet discharge pipe.

[0007] Preferably, the bottom end of the mounting frame is fixedly connected with a connecting plate, on which two groups of first locking rods and second locking rods are respectively screwed, and the ends of each of the first locking rods and the second locking rods are rotatably connected with the first clamping plate and the second clamping plate.

[0008] Preferably, the top end of the mounting frame is fixedly connected to the rubber ring via a plurality of bolts, and a gasket is sleeved on each bolt.

[0009] The advantages of the utility model are as follows: the bottom of the sealing rubber plate is fixed by the second clamping plate, and the top of the sealing rubber plate is fixed by the rubber ring, so that the sealing rubber plate can be effectively used for auxiliary sealing under the premise of convenient top plug-in installation, and the leakage of acidic gas can be effectively reduced. At the same time, if the material ages after long-term use, the small amount of leaked gas can be blown away by the straight-tube fan, thereby ensuring the normal use of the collector. At the same time, the installation is simple and convenient, and the disassembly is easy, and the cost will not be increased. Description of the drawings:

[0010] Figure 1 It is a schematic diagram of the structure of the utility model;

[0011] Figure 2 It is a top view of the utility model;

[0012] Figure 3 It is a schematic diagram of the connection between the sealing rubber plate and the first clamping plate of the utility model.

[0013] In the figure: bottom flow outlet discharge pipe 1, bracket 2, straight fan 3, rubber ring 4, mounting frame 5, sealing rubber plate 6, first clamping plate 7, connecting plate 8, first locking rod 9, second clamping plate 10, second locking rod 11. Specific implementation method:

[0014] like Figures 1 to 3 As shown, an auxiliary seal of a thickener includes an underflow outlet discharge pipe 1, a bracket 2 is provided on one side of the underflow outlet discharge pipe 1, a straight-tube fan 3 is fixedly installed on one side of the bracket 2, the bracket 2 is used to support the straight-tube fan 3 and a mounting frame 5, one end of the bracket 2 is fixedly connected to the mounting frame 5, a rubber ring 4 is fixedly installed on the top of the mounting frame 5, the rubber ring 4 plays a role of tightening the top so that the sealing rubber plate 6 remains tight, the mounting frame 5 plays a role of fixed support, the bottom end of the rubber ring 4 is fixedly connected to the sealing rubber plate 6, the sealing rubber plate 6 is sleeved on the underflow outlet discharge pipe 1, and the sealing rubber plate 6 is used to assist in sealing, so as to avoid leakage of acidic gas at the connection, and even if a small amount of gas leaks, it can be blown away by supporting the straight-tube fan 3 to ensure the stable operation of the collector.

[0015] The bottom end of the mounting frame 5 is fixedly connected with a connecting plate 8, on which two groups of first locking rods 9 and second locking rods 11 are respectively screwed, and the ends of each of the first locking rods 9 and the second locking rods 11 are rotatably connected with the first clamping plate 7 and the second clamping plate 10. In this way, by rotating the corresponding first locking rods 9 and the second locking rods 11, the first locking rods 9 and the second locking rods 11 can lock the middle and bottom of the sealing rubber plate 6. The bottom locking of the sealing rubber plate 6 is to ensure the overall fixation and sealing, while the locking of the middle part is to enable the sealing rubber plate 6 to fit tightly against the connection to avoid gas leakage. The overall operation is simple and convenient, and disassembly is easy.

[0016] The top of the mounting frame 5 is fixedly connected to the rubber ring 4 through a plurality of bolts, and a gasket is sleeved at each bolt to increase the contact area, prevent the rubber ring 4 from being tightened and torn, and maintain the stability of the fixation.
