Description

Technical Field

[0001] The utility model relates to the technical field of emergency repair when a discharge outlet of equipment such as a box body, a tank body, a trough body, etc. for containing and conveying liquid is damaged, and specifically relates to an efficient and convenient discharge outlet emergency repair and plugging device. Background Art

[0002] In actual industrial production, a large number of liquid containing and conveying equipment are needed, such as material storage tanks, mixing tanks, reaction tanks and flotation machine tanks. The discharge ports at the bottom or side walls of these tanks and tanks are easily corroded or the entire discharge short pipe is corroded and falls off. Emergency plugging is required when the discharge port leaks.

[0003] In the key link of mineral processing, a method often used in the ore selection process is flotation separation. The corresponding equipment is the flotation machine. Its specific structure and working principle are as follows Figure 1 , Figure 2 As shown. Component 1 is a concrete foundation, a metal tank body used to carry tens or even hundreds of tons of slurry. Component 2 is a cylindrical flotation machine tank body, which is made of steel and coated with wear-resistant and corrosion-resistant materials. Component 3 is a barrel-shaped stator fixed at the bottom of the tank body. Component 4 is a sloped annular false bottom with a hole 5 on the false bottom. Component 6 is a steel rubber-coated blocking ball, whose function is: when carrying liquid, the blocking ball component is passed through the hole 5 to block the hole 2-1 at the bottom of the tank body. Because the elasticity of the rubber on its surface has a certain sealing effect, and the liquid pressure at the bottom of the tank body is relatively large, it can achieve a good blocking effect; and when it is necessary to release the liquid material in the tank body, the blocking ball component is lifted up, and the material in the tank body is discharged through the hole 2-1. Component 7 is a stirring component. Its function is to be driven by the upper transmission device and cooperate with the stator 3 to complete the flotation operation.

[0004] In the actual production operation process, the ball blocking assembly 6 is required to seal the hole 2-1. However, due to the complex structure of the bottom of the tank body, the small space, the corrosiveness of the liquid itself, and its erosion and friction on the metal bottom, sometimes the edges of the circular hole 2-1 and the metal around the hole will be corroded during normal production. Since the material in the tank is heavy and the bottom pressure is high, when corrosion occurs, it often causes huge leakage, and the entire system has to be stopped for maintenance. The conventional maintenance method is to empty the tank body, completely remove the false bottom 5, remove the metal bottom plate around the hole 2-1, and then re-feed, weld, open holes, and trim and polish the edges of the holes. The entire maintenance time exceeds 18 hours, which seriously affects the continuity of the entire production system. Utility Model Content

[0024] Example

[0025] like Figure 1-4 The present embodiment provides an efficient and convenient discharge port emergency repair and plugging device, including an upper pressure plate 8-1 and a lower pressure plate 8-3. A through hole is provided in the center of the upper pressure plate 8-1. Corresponding bolt holes are also provided on the upper pressure plate 8-1 and the lower pressure plate 8-3. The upper pressure plate 8-1 and the lower pressure plate 8-3 are connected together by a bolt assembly. An upper sealing filler 8-2 is provided at the edge of the lower surface of the upper pressure plate 8-1, and a lower sealing filler 8-4 is provided at the edge of the upper surface of the lower pressure plate 8-3.

[0026] The bolt assembly consists of a tightening bolt 8-5, a hexagonal nut 8-6 and a flat washer 8-7 thereon. The tightening bolt 8-5 passes through the upper pressure plate 8-1 and the lower pressure plate 8-3 in sequence, and the flat washer 8-7 is fastened to the lower pressure plate 8-3 by a hexagonal nut 8-6 set on its lower end.

[0027] The upper pressure plate 8-1 and the lower pressure plate 8-3 are both composed of a circular plate and an annular plate arranged at the edge of one side of the circular plate. The upper sealing filler 8-2 and the lower sealing filler 8-4 are both annular structures. The upper sealing filler 8-2 is arranged on the inner side of the annular plate of the upper pressure plate 8-1, and the lower sealing filler 8-4 is arranged on the inner side of the annular plate of the lower pressure plate 8-3.

[0029] The working principle of the utility model is that when the edge corrosion and the surrounding corrosion of the hole 2-1 at the bottom of the metal mixing tank occur, the ball plugging assembly 6 will not be able to be effectively sealed or even fall off as a whole, resulting in a large amount of leakage. In this case, the utility model can be used to achieve emergency plugging. The specific method is:

[0032] 3. Place the upper pressing plate 8-1 above the sealing filler 8-2;

[0033] 4. Insert the tightening bolts 8-5 (several) into the openings on the upper pressure plate 8-1;

[0034] 5. Install the lower sealing filler 8-4 into the lower pressing plate 8-3 and lift the whole upward;

[0035] 6. Pass the tightening bolts 8-5 through the corresponding holes on the lower pressure plate 8-3;

[0036] 7. Install the flat washers 8-7 (several) and hexagon nuts 8-6 (several) on the tightening bolts 8-5 in sequence and tighten them;

[0037] 8. By tightening the hexagonal nut 8-6, the upper pressure plate 8-1 and the lower pressure plate 8-3 will squeeze the upper packing 8-2 and the lower sealing packing 8-4 more tightly under the tightening force, thereby achieving the sealing effect;

[0038] 9. Reinsert the ball blocking assembly 6 into the hole of the upper pressure plate 8-1 to restore the seal. The entire production system can resume stable production within one hour, avoiding various unexpected losses caused by long-term shutdown. In the later stage, the entire line can be shut down in an orderly manner, and then a thorough inspection and maintenance can be organized.

[0039] Compared with the traditional solution which requires a long processing time and causes serious economic losses, the utility model solves the problem of economic losses caused by the shutdown of the entire production line.
