Description

Technical Field

[0001] This utility model relates to the field of tailings slurry discharge technology, and in particular to a foam reduction structure for tailings slurry pipe outlets. Background Technology

[0002] Tailings dams are places used to store tailings slurry. They are usually constructed by damming valley mouths or enclosing land. Tailings dams are not only a man-made debris flow hazard with high potential energy and the risk of dam failure, but also easily cause major accidents once they fail. Therefore, the management and maintenance of tailings dams are crucial. Tailings slurry refers to the slurry-like substance stored in tailings dams, which is formed by the mixture of tailings discharged after ore beneficiation and other industrial waste. Tailings slurry needs to be discharged regularly.

[0003] However, when tailings slurry is discharged through pipelines, the rapid outflow of tailings slurry causes it to directly impact the air, generating a large amount of foam and slowing down the gas escape time from the tailings slurry. Utility Model Content

[0004] The technical problem this invention aims to solve is that when tailings slurry is discharged through a pipeline, the excessively fast outflow of the tailings slurry causes it to directly impact the air, generating a large amount of foam and slowing down the gas escape time from the tailings slurry.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A foam reduction structure for a tailings slurry pipeline outlet includes a tailings slurry conveying pipe. One end of the tailings slurry conveying pipe is detachably connected to a discharge pipe via a flange and bolts. The other end of the discharge pipe is detachably connected to a foam reduction pipe. An adjusting baffle is installed inside the foam reduction pipe. A positioning shaft is inserted through one end of the adjusting baffle. Both ends of the positioning shaft are rotatably inserted into the foam reduction pipe. An adjusting hydraulic rod is installed between the bottom surface of the adjusting baffle and the foam reduction pipe. Rotating pins are inserted through both ends of the adjusting hydraulic rod. The adjusting hydraulic rod, adjusting baffle, and foam reduction pipe are rotatably connected via the rotating pins.

[0007] Preferably, the surface of the adjusting baffle is fixed with a plurality of linearly distributed fixing rods, and a guide plate is rotatably mounted on the outer side of the fixing rods.

[0008] Preferably, adjacent guide plates are parallel to each other, and magnets are embedded in the bottom of the guide plates. The guide plates are magnetically attracted and fixed to the adjusting baffle by the magnets.

[0009] Preferably, both sides of the guide plate are provided with multiple positioning holes arranged in a rectangular array, and multiple splicing rods are detachably installed between two adjacent guide plates.

[0010] Preferably, both ends of the splicing rod are rotatably inserted into the inner side of the positioning hole, and a rotating baffle is fixed at the bottom of the splicing rod, the thickness of which is half the diameter of the splicing rod.

[0011] Preferably, sealing strips are fixed on both sides of the adjusting baffle, one end of the sealing strip is penetrated by the positioning shaft, and the thickness of the sealing strip is greater than the distance between the adjusting baffle and the foam reduction tube.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The tilt angle of the adjusting baffle is changed by adjusting the hydraulic rod to change the discharge speed of the tailings slurry. Splicing rods and rotating baffles are added between adjacent guide plates. The rotating baffles are used to further slow down the flow rate of the tailings slurry to avoid the tailings slurry forming foam due to direct impact with air when discharged.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figures 1 to 3As shown, a foam reduction structure for a tailings slurry pipeline outlet includes a tailings slurry conveying pipe 1. One end of the tailings slurry conveying pipe 1 is detachably connected to a discharge pipe 2 via a flange and bolts. The other end of the discharge pipe 2 is detachably connected to a foam reduction pipe 10. An adjusting baffle 3 is installed inside the foam reduction pipe 10. A positioning shaft 6 is inserted through one end of the adjusting baffle 3. Both ends of the positioning shaft 6 are rotatably inserted into the foam reduction pipe 10. An adjusting hydraulic rod 11 is installed between the bottom surface of the adjusting baffle 3 and the foam reduction pipe 10. Rotating pins are inserted through both ends of the adjusting hydraulic rod 11. The adjusting hydraulic rod 11 is rotatably connected to the adjusting baffle 3 and the foam reduction pipe 10 via rotating pins. By adjusting the hydraulic rod 11, the upward tilt angle of the unfixed end of the adjusting baffle 3 is changed, increasing the resistance of the tailings slurry flowing from the surface of the adjusting baffle 3, thereby changing the flow velocity of the tailings slurry.

[0021] Both sides of the adjusting baffle 3 are fixed with sealing strips 7. One end of the sealing strip 7 is penetrated by the positioning shaft 6, and the thickness of the sealing strip 7 is greater than the distance between the adjusting baffle 3 and the foam reduction pipe 10. This seals the gap between the adjusting baffle 3 and the foam reduction pipe 10, preventing tailings slurry from entering the adjusting baffle 3 from the gap between the adjusting baffle 3 and the foam reduction pipe 10 and coming into contact with the adjusting hydraulic rod 11.

[0022] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4 As shown, multiple linearly distributed fixing rods 5 are fixed on the surface of the adjusting baffle 3. A guide plate 4 is rotatably installed on the outer side of the fixing rod 5. Adjacent guide plates 4 are parallel to each other. A magnet is embedded in the bottom of the guide plate 4. The guide plate 4 is magnetically attracted and fixed to the adjusting baffle 3 by the magnet. An adjustable guide plate 4 is installed on the surface of the adjusting baffle 3 to change the flow direction of the tailings slurry, so as to avoid the tailings slurry directly impacting the air inlet and generating foam.

[0023] In this embodiment, both sides of the guide plate 4 are provided with a plurality of rectangular arrayed positioning holes 12. A plurality of splicing rods 8 are detachably installed between two adjacent guide plates 4. The two ends of the splicing rods 8 are rotatably inserted into the inside of the positioning holes 12. A rotating baffle 9 is fixed at the bottom of the splicing rod 8. The thickness of the rotating baffle 9 is half the diameter of the splicing rod 8. By installing a plurality of splicing rods 8 and rotating baffles 9 between adjacent guide plates 4, the tailings slurry comes into contact with the rotating baffle 9 when flowing between adjacent guide plates 4. The rotating baffle 9 affects the flow of the tailings slurry and reduces the flow rate of the tailings slurry.

[0024] Working principle: When tailings slurry is discharged from the tailings dam through tailings slurry conveying pipe 1 and discharge pipe 2, the lifting angle of the unfixed end of the adjusting baffle 3 is adjusted according to the amount of tailings slurry discharged. The adjusting hydraulic rod 11 is activated, causing the end of the adjusting hydraulic rod 11 connected to the adjusting baffle 3 to extend. At this time, the unfixed end of the adjusting baffle 3 rotates upward around the axis of the positioning shaft 6. After the adjusting baffle 3 is raised to a certain angle, the adjusting hydraulic rod 11 is closed. After the tailings slurry is discharged from the end of the discharge pipe 2, the tailings slurry flows along the surface of the raised adjusting baffle 3. When the tailings slurry flows upward, the flow velocity will decrease, thereby preventing the tailings slurry from flowing too fast and directly colliding with the air to generate foam. After the angle of the baffle 3 is adjusted, the guide plate 4 is manually pushed to rotate around the axis of the fixed rod 5 to change the orientation of the unfixed end of the guide plate 4. Alternatively, splicing rods 8 and rotating baffles 9 can be installed between adjacent guide plates 4 to obstruct the flow of tailings slurry, thereby reducing the flow velocity of the tailings slurry. Or, the flow direction of the tailings slurry can be changed by the angle of the guide plate 4, thereby preventing the tailings slurry from flowing too fast and directly colliding with the air to generate foam.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
