Description

Technical Field

[0001] The present invention relates to the technical field of equipment for treating and repairing soil in mining areas, and in particular to equipment for treating and repairing soil heavy metal pollution in mining areas. Background Art

[0002] With the continuous development and utilization of mineral resources, the problem of heavy metal pollution in mining soil is becoming increasingly serious. At present, the damaged area of ​​mines in China is nearly 3 million hectares, and it is still growing at a rate of 30,000 to 40,000 hectares per year. The traditional treatment of heavy metal pollution in mining soil is still based on the combination of manual and single-function equipment. It has problems such as low efficiency and high cost, and it is difficult to meet the current treatment needs of heavy metal contaminated soil in mining areas.

[0003] On the one hand, the mining area has produced a large amount of heavy metal-contaminated waste soil and waste residue during the long-term mining process. These waste soil and waste residues have large particles and high porosity, and cannot retain water and fertilizer. The existing treatment and restoration equipment cannot solve the above problems at one time, and often requires the combination of manual labor and the use of equipment of different functions and types to work together, which greatly reduces the efficiency of treatment and restoration and increases the cost of treatment and restoration. On the other hand, the traditional model of combining manual labor with single-function equipment often leads to many uncontrollable factors due to human factors and the incoherent connection between various equipment. There are disadvantages such as uneven addition of treatment and restoration materials, which leads to increased treatment and restoration costs and poor treatment and restoration effects.

[0004] In order to solve the current huge and rapidly growing demand for the treatment and remediation of heavy metal pollution in mining areas, it is necessary to overcome the shortcomings of existing treatment and remediation equipment. Based on this, there is an urgent need for an integrated device that integrates multiple different treatment links, optimizes the process flow, improves treatment efficiency, and reduces treatment costs.

[0042] Working principle:

[0043] When in use, the carriage 1 is driven to move by an external moving device. During the movement, the waste soil and slag in the mining area are transported and preliminarily crushed by the feeding device 3, and then transported to the screening device 5 for screening and treatment, and the rolling mechanism 56 is used for secondary crushing to remove larger particles of soil and impurities. The screened waste soil and slag enters the dosing device 6 for dosing, repair and fertilization treatment, and finally the treated soil is discharged from the discharge port 2;

[0044] When the carriage 1 moves, the waste soil and slag are shoveled onto the feeding device 3 through the excavation block 42, and the rotating roller 36 on the fixed frame 31 is driven to rotate through an external power source, so that the rotating roller 36 drives the conveyor belt 32 to operate on the fixed roller 33 and the adjusting roller 310, thereby conveying the soil. When the soil is conveyed to the bottom of the crushing rod 35, the rotating roller 36 drives the driving gear 314 to rotate through the first pulley group 312, and through the meshing of the driving gear 314 and the connecting gear 313, the rotating rod 34 fixedly connected to the connecting gear 313 is driven to rotate, so that the rotating rod 34 drives the fixedly connected crushing rod 35 to rotate, thereby crushing the compacted waste soil and slag into small-sized particles suitable for pollution control and remediation;

[0045] Through the adjustment mechanism 4, when waste soil and waste residue at different depths are transported, the hydraulic rod 45 pushes the connecting plates 41 at both ends to slide on the fixed frame 31, and drives the excavation block 42 to move, so as to adjust the height of the excavation block 42. During the adjustment process, the connecting plate 41 drives the rack 44 to move, so that the rack 44 drives the meshing adjustment gear 311 to rotate, so that it drives the handle 37 to rotate, so that the handle 37 drives the adjustment roller 310 at the other end to rotate, and the angle of the conveyor belt 32 is changed through the adjustment roller 310. When the handle 37 moves with the connecting plate 41, the guide column 39 slides in the guide groove 43, so that the connecting plate 41 completes the support of the handle 37 at different angles, so that the angle of the conveyor belt 32 is changed at the same time when the height of the excavation block 42 is adjusted;

[0046] When the compacted waste soil and waste residue is transported to the screening device 5, the straight vibrator 52 is started to drive the vibration box 51 to vibrate, so that the small-sized particles move while vibrating on the screen 57 on the vibration box 51. With the vibration of the screen 57, the small-sized particles can be loosened and pass through the screen 57 to fall onto the drainage plate 59 below. Through the inclination angle of the drainage plate 59, the qualified soil slides through the drainage plate 59 into the carriage 1 at the lower end of the dosing device 6 to perform the next operation;

[0047] When larger particles of small size enter under the rolling mechanism 56, the driving motor 54 drives the driving rod 55 to rotate, and drives the fixedly connected rotating disk 561 to rotate. As the rotating disk 561 rotates, the swinging rod 562 rotates in the rotating disk 561 under the action of centrifugal force, and squeezes the external rubber pad 564, which is expanded outward from the rotating disk 561, so that the swinging rod 562 performs secondary knocking and crushing on the larger waste soil and waste residue on the screen 57, so that the soil is no longer compacted and can pass through the screen 57. The vibrator 52 drives the vibration box 51 to vibrate, and the larger waste soil, waste residue and impurities move to the drainage plate 58, and enter the bellows 53 through the angle of the drainage plate 58, and are discharged through the carriage 1. When no more screening is performed, the drive motor 54 is turned off, and the swing rod 562 is rotated and reset under the action of the torsion spring 563. At this time, the magnetic connection between the magnetic block 565 and the stopper 566 allows the rubber pad 564 to seal the outside of the swing rod 562 again to prevent small-sized particles from entering and affecting the operation of the swing rod 562.

[0048] When the sieved small-size soil particles enter the bottom of the dosing device 6, the feed roller 65 is driven to rotate by an external power supply, and the soil is stirred and transported by the spiral feed roller 65. The connecting rod 66 is connected with the collecting roller 62 through the connection of the second pulley group 64. When the notch 63 on the collecting roller 62 is at the top, the soil conditioner in the material box 61 enters the notch 63. When it rotates to the bottom, the soil conditioner enters the soil below, and the soil conditioner and the soil are stirred by the feed roller 65. Therefore, when the feed roller 65 rotates one circle, the collecting roller 62 rotates one circle, thereby completing the uniform stirring of the soil conditioner and the small-size soil particles, and the soil mixed with the soil conditioner is transported by the feed roller 65 and discharged from the discharge port 2.
