Description

Technical Field

[0001] The utility model relates to the technical field of tailings equipment, in particular to a tailings dewatering device for mining. Background Art

[0002] Mining tailings dewatering equipment is a key equipment used to separate the moisture in the tailings after ore processing. Its main purpose is to significantly reduce the moisture content in the tailings, thereby reducing the footprint of the tailings pond and the risk of secondary pollution, while effectively recovering useful resources and saving tailings treatment costs;

[0003] When the tailings dewatering screen is dewatering the tailings, due to the small particle diameter and high water content of some tailings, the tailings will be accumulated on the screen plate to a certain thickness, thereby affecting the dewatering effect of the tailings. Therefore, the existing Chinese utility model patent disclosed by the publication number: CN215742203U: Vibrating dewatering screen, the application includes a screen frame, a screen fixed on the screen frame, and a material baffle assembly, the discharge end of the screen is fixed with a discharge plate, the side of the discharge plate is in contact with the side of the discharge end of the screen, the material baffle assembly is fixed on the discharge plate, and the bottom of the material baffle assembly is in contact with the upper surface of the discharge plate, which can separate the material particles during the dehydration process. The moisture on the surface of the material is squeezed out to reduce the moisture content of the material. However, the application sets a first baffle plate and a second baffle plate on the front side of the screen frame. The material is accumulated at the baffle assembly, and the moisture on the surface of the material particles is squeezed out through the mutual squeezing of the material layer thickness. However, since the overall particle size of the tailings after dehydration is relatively small, if the fluidity of the tailings is poor, it is easy to cause the tailings to form a blockage at the baffle plate. At the same time, if the equipment is not maintained and cleaned in time during operation, the tailings particles may gradually accumulate and solidify on the baffle plate, further aggravating the risk of blockage. Such blockage will not only affect the dehydration efficiency of the equipment, but may also damage the normal operation of the equipment and even cause failures. Utility Model Content

A crossbeam 8 is provided, on which two vibration motors 9 are fixedly mounted, and the two vibration motors 9 are electrically connected to an external main controller through connecting lines. A buffering material-beating mechanism 10 is also provided in the screen box 3 located in front of the crossbeam 8, and the buffering material-beating mechanism 10 includes two mounting shaft seats 11, and the two mounting shaft seats 11 are respectively fixedly mounted on one side of the screen box 3, and a mounting shaft 12 is movably mounted between the two mounting shaft seats 11, and a plurality of buffer wheels 13 are movably mounted on the outer side of the mounting shaft 12, and a material-beating rod 14 is also movably mounted on the outer side of the buffer wheel 13.

[0027] like Figure 2-Figure 5 As shown, a guide beam 16 is fixedly installed in the screen box 3 located in the front side of the mounting shaft 12, and a slide groove 17 is opened in the guide beam 16. With the help of the setting of the guide beam 16, a stable guide can be provided for the horizontal movement of the punching rod 14. A motor 15 is fixedly installed on one side of the screen box 3, and the motor 15 is electrically connected to the external main controller through a connecting line. A plurality of limit screws 18 are threadedly connected to the mounting shaft seat 11, and a ball 24 is rotatably installed at one end of the limit screw 18, and the ball 24 abuts against one end of one of the buffer wheels 13. With the help of the setting of the limit screw 18, a plurality of buffer wheels 13 installed on the outside of the mounting shaft 12 can be squeezed and fixed to prevent the buffer wheel 13 from shaking during installation. The longitudinal section of the mounting shaft 12 is a regular hexagon, and rotating shafts 19 are fixedly installed on both sides of the mounting shaft 12. The two rotating shafts 19 are rotatably installed in the corresponding mounting shaft seats 11, and one of the rotating shafts 19 is fixedly connected to the output end of the motor 15.

[0028] like Figure 2-Figure 4As shown, a plurality of convex strips 20 are fixedly installed on the outer side of the buffer wheel 13, a guide groove 21 is also opened on the outer side of the buffer wheel 13, and a mounting shaft hole 22 is opened at the center position inside the buffer wheel 13. The buffer wheel 13 is inserted and installed on the mounting shaft 12 through the mounting shaft hole 22. The buffer wheel 13 is driven to rotate by the motor 15 and the mounting shaft 12, so that the paving thickness and the feeding speed of the dewatered tailings can be controlled, thereby improving the dewatering effect. A ball seat 23 is fixedly installed on one side of the beating rod 14, and the ball seat 23 is slidably installed in the guide groove 21. The side of the beating rod 14 away from the ball seat 23 is slidably installed in the slide groove 17 and is arranged obliquely. By rotating the buffer wheel 13 and cooperating with the guide groove 21 on the outer side, the beating rod 14 can be made to reciprocate horizontally, thereby breaking up and discharging the tailings agglomerated after dehydration.

[0029] It should be noted that the utility model is a tailings dewatering device for mining.

Then, the two vibration motors 9 on the crossbeam 8 are started. Under the action of vibration, the tailings form a layer of particle accumulation on the screen surface at the bottom of the screen box 3. The larger particles are blocked above the screen surface to form a slurry layer, while the smaller particles and moisture enter the underflow box 2 below the screen box 3 through the sieve holes at the bottom of the screen box 3 for collection. Then, the vibration generated by the vibration motor 9 and the spring support 4 can be used to make the particle layer separated in the screen box 3 pass through the screen surface. The tailings gradually move toward the buffering mechanism 10 through vibration, that is, the dehydrated tailings move toward the buffer wheel 13 through the vibration of the screen box 3, and the distance between the buffer wheel 13 and the screen box 3 can be used to slow down the discharge speed of the tailings, and the motor 15 drives the rotating shaft 19 and the mounting shaft 12 to rotate, so that the rotating mounting shaft 12 can simultaneously control the thickness of the tailings discharge, and effectively prevent the tailings discharge from being blocked. At the same time, when the buffer wheel 13 rotates, the guide groove 21 on the outer side of the buffer wheel 13 slides on the ball seat 23 on one side of the beating rod 14, so that the beating rod 14 cooperates with the guide beam 16 to realize reciprocating horizontal motion through the path of the guide groove 21, so that the inclined beating rod 14 can break up the agglomerated tailings at the discharge position on the front side of the screen box 3.
