[0002] Mine environmental pollution is a major challenge facing the current environmental protection field. The main source of mine environmental pollution comes from solid waste in mines, including ore, waste rock, fine dust, tailings, gangue and radioactive substances.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Reference Figure 1-11An embodiment of the present invention discloses a mine pollutant treatment device, which is used to solve the problem that the current treatment device is not convenient for separately treating solid objects of different sizes. Specifically, the device includes a movable frame 1. As a preferred embodiment, four rollers are installed at the four corners of the bottom of the frame 1 in this embodiment to realize the walking movement of the frame 1. The rollers can be driven by a motor. This method is a conventional method of technicians in the relevant field and will not be described in detail here.

[0041] and a scraping mechanism 2 mounted on the frame 1 and a lifting and separating mechanism 3 located on the side of the scraping mechanism 2;

[0042] The lifting and separation mechanism 3 is used to lift and screen the materials delivered by the scraper mechanism 2. A stacking unloading mechanism 4 and a slag unloading mechanism 5 are also fixedly installed above the frame 1. The stacking unloading mechanism 4 is used to transfer the block materials delivered by the lifting and separation mechanism 3, and the slag unloading mechanism 5 is used to transfer the granular materials delivered by the lifting and separation mechanism 3.

[0043] Reference Figure 3 , 4 In some embodiments, the scraper mechanism 2 of the present invention includes a shovel arm 21, and a circular tube 22 is rotatably connected to the end surface of the shovel arm 21. Specifically, a receiving groove is provided at the front end of the shovel arm 21, and the circular tube 22 rotates in the receiving groove. A plurality of material shovels 23 are distributed circumferentially on the outer periphery of the circular tube 22, and a plurality of material guide ports 24 are also provided on the outer periphery of the circular tube 22. The material guide ports 24 are located in the orthographic projection plane of the material shovel 23, wherein a driving component 25 for driving the circular tube 22 to rotate is provided on the shovel arm 21.

[0044] That is to say, in the process of collecting pollutants in the present invention, the driving component 25 drives the circular tube 22 to rotate, and the circular tube 22 drives multiple shovels 23 to rotate. After the shovels 23 scrape the pollutants in, when the shovels rotate to the top, under the action of gravity, the pollutants enter the interior of the circular tube 22 along the guide port 24, so as to be subsequently transported outward to the lifting and separation mechanism 3.

[0045] Reference Figure 4 On the basis of the above embodiment, the driving assembly 25 of the present invention comprises a first motor 251 fixed on the shovel arm 21, the first motor 251 is mounted on the shovel arm 21 through a fixing seat, and a ring gear portion 221 is provided on the outer periphery of the circular tube 22, and a first gear 252 meshing with the ring gear portion 221 is fixed to the shaft end of the first motor 251;

[0046] A feeding assembly 26 is also provided on the inner side of the circular tube 22 , and the feeding assembly 26 is in transmission with the driving assembly 25 .

[0047] Reference Figure 4 Furthermore, in this embodiment, the feeding assembly 26 includes an auger 261 rotatably connected to the inner side of the circular tube 22, and a second gear 262 is fixedly mounted on the shaft end of the auger 261, wherein a third gear 263 is also rotatably connected to the outer side of the shovel arm 21, and the second gear 262 is meshed with the first gear 252 via the third gear 263 for transmission.

[0048] That is, during the specific working process, when the first motor 251 drives the ring tooth portion 221 to rotate through the first gear 252, the shovel 23 transports the pollutants along the material guide port 24 to the inside of the circular tube 22 during rotation. At the same time, the first gear 252 drives the second gear 262 to rotate through the third gear 263, and drives the auger 261 to rotate through the second gear 262, thereby transporting the pollutants to the tail end of the circular tube 22 until they are transported to the lifting and separation mechanism.

[0049] Reference Figure 5 , 6 7. In a further embodiment, the lifting and separation mechanism 3 of the present invention includes a lifting frame 31 fixed on the side of the shovel arm 21, and the lifting frame 31 is arranged obliquely. A conveyor belt 33 is rotatably connected to the inner side of the lifting frame 31 through two roller shafts 32, and one of the roller shafts 32 is connected to the rotating part of the feeding assembly 26. Specifically, the rotating part described in this embodiment is the other shaft end of the above-mentioned auger 261, and a feed port 34 and a discharge port 35 are respectively provided at the bottom and top of the lifting frame 31, and a plurality of slag discharge holes 36 are arranged at intervals on the end surface of the conveyor belt 33, and a plurality of partitions 37 are obliquely fixed on the end surface of the conveyor belt 33.

[0050] In summary, when the waste enters the interior of the lifting frame 31 through the feed port 34 along the circular tube 22, it will first fall onto the end surface of the conveyor belt 33. Since the conveyor belt 33 is provided with a plurality of slag discharge holes 36, the particulate pollutants will fall from the slag discharge holes 36 to the lower side of the lifting frame 31, and then enter the crushing and incineration mechanism 6.

[0051] The block-shaped pollutants located on the upper side of the conveyor belt 33 move upward driven by the partition 37 until the pollutants move to the discharge port 35 of the lifting frame 31. At this time, since the partition 37 is inclined, specifically, the partition 37 is inclined toward one side of the feed port 34. Therefore, when the partition 37 is at the discharge port 35, it will be discharged from the discharge port 35 along the inclined surface of the partition 37 and finally unloaded into the stacking mechanism 4.

[0052] It should be noted that in this embodiment, the width of the conveyor belt 33 is the same as the inner width of the lifting frame 31. This design is to prevent smaller particles of pollutants from falling through the gap between the conveyor belt 33 and the inner side of the lifting frame 31. Of course, the width of the partition 37 can also be set to be consistent with the width of the conveyor belt 33 to ensure the stability of the lifting and transportation.

[0053] Reference Figure 7 , 8 , in some embodiments, the present invention further comprises a crushing and incineration mechanism 6;

[0054] The crushing and incineration mechanism 6 includes a heating frame 61 fixed to the lower side of the lifting frame 31 and a preheating frame 62 installed inside the heating frame 61;

[0055] Reference Figure 5 The lower side of the lifting frame 31 is provided with a plurality of slag discharge holes 38. The particulate pollutants dropped from the slag discharge holes 36 on the conveyor belt 33 will enter the inner side of the heating frame 61 along the slag discharge holes 38. Of course, in actual operation, not all the dropped particulate pollutants will be discharged along the slag discharge holes 38. Therefore, in order to avoid residue, the partition 37 located on the lower side of the conveyor belt 33 in this embodiment can contact the inner bottom and the circumferential corner of the lower end of the lifting frame 31. In this way, when the partition 37 is in contact with the inner bottom of the lifting frame 31, the particulate pollutants will enter the inner side of the heating frame 61 along the slag discharge holes 38. As the conveyor belt 33 rotates, when it is located below the conveyor belt 33, it will scrape the particle pollutants to move them, so that they are discharged outward along the slag discharge hole 38 on the lifting frame 31, and the particle pollutants that fail to enter the slag discharge hole 38 will continue to move upward under the drive of the partition plate 37 until they are flipped to the upper side of the conveyor belt 33, and then the particle pollutants continue to fall from the slag discharge hole 36 and move out along the slag discharge hole 38, and so on and so forth, ensuring that the particle pollutants can smoothly enter the heating frame 61;

[0056] Reference Figure 7 A guide plate 63 is obliquely arranged in the preheating frame 62, an exhaust pipe 64 is opened on the end surface of the guide plate 63, and a heating assembly 65 is arranged at the bottom of the heating frame 61. As a preferred embodiment, the heating assembly 65 described in this embodiment includes a gas tank and a heating plate connected to the gas tank, and a plurality of nozzles are arranged on the heating plate to notify the configuration of an ignition device. The gas path connection combustion method is a conventional means for technicians in the relevant field, and will not be repeated here. Specifically, in this embodiment, the bottom of the heating frame 61 is burned and heated by the nozzle on the heating plate, so that the inner side of the heating frame 61 can be in a high temperature state to achieve high-temperature incineration of particulate pollutants.

[0057] Reference Figure 8It should be noted that in this embodiment, obliquely distributed air holes are provided at the bottom of the preheating frame 62. When the heating frame 61 is heated at high temperature, part of the high-temperature gas enters the guide plate 63 along the air holes, and is then transported to the inner side of the lifting frame 31 along the slag discharge hole 38 through the exhaust pipe 64 on the guide plate 63. In this way, the preheating operation of the particulate pollutants can be realized to improve the heating efficiency of the particulate pollutants entering the heating frame 61.

[0058] Reference Figure 8 In a further embodiment, the guide plate 63 described in the present invention is movably connected to the preheating frame 62. Specifically, in this embodiment, a second motor 621 is fixed to one end of the preheating frame 62, and a cam shaft 622 is fixedly installed on the shaft end of the second motor 621. A slot is provided at the end of the guide plate 63, and one end of the cam shaft 622 slides in the slot, so that when the second motor 621 rotates, the guide plate 63 is driven to move back and forth through the cam shaft 622.

[0059] The purpose of adopting the structural design of reciprocating sliding of the guide plate 63 is: first, to ensure its feeding capacity for particulate pollutants. Due to its reciprocating shaking, when the particulate pollutants fall above the slag discharge hole 38, they will move downward quickly under the shaking force of the guide plate 63, so as to improve the mobility of the particulate pollutants;

[0060] Secondly, the shaking guide plate 63 can also drive the exhaust pipe 64 to move, so that the hot air can be evenly introduced into the inner side of the lifting frame 31 to ensure the stability of preheating.

[0061] Reference Figure 7 , 8 9. On the basis of the above embodiment, in the present invention, two crushing rollers 67 are rotated inside the heating frame 61, and the two crushing rollers 67 are driven to rotate by a driving member 66. Specifically, the driving member 66 in this embodiment is a third motor, and the shaft ends of the two crushing rollers 67 are fixed with fourth gears, and the two fourth gears are meshed with each other, wherein the third motor and the shaft end of one crushing roller 67 are driven by a belt and a pulley;

[0062] The two crushing rollers 67 are located at the lower end of the guide plate 63, and the inner side of the heating frame 61 is also rotatably connected to two pulleys 68, wherein the shaft end of one of the pulleys 68 is also transmitted to the above-mentioned pulley through the pulley, and the three pulleys are distributed in a triangular structure, that is, in the present invention, a third motor is used to simultaneously drive the crushing roller 67 and the pulley 68 to rotate to ensure the consistency of the movements of the two, and a conveyor belt 69 is rotatably connected between the two pulleys 68, and a plurality of storage troughs 691 are provided on the surface of the conveyor belt 69.

[0063] Specifically, when the particulate contaminants are heated at high temperature, they will become brittle. Therefore, when they enter between the two crushing rollers 67, they will be crushed into fine particles by the two crushing rollers 67. Thereafter, the fine particles fall into the storage trough 691 of the conveyor belt 69 for lifting to realize the transportation of the fine particles. It should be noted that the bottom of the conveyor belt 69 described in this embodiment is in contact with the bottom of the heating frame 61 to ensure the lifting stability of the fine particles.

[0064] Reference Fig. 9 , 10 In some embodiments, the slag unloading mechanism 5 in the present invention includes a semicircular tube 51 fixed and connected to the side of the heating frame 61, and a discharge auger 52 is rotatably connected to the inner side of the semicircular tube 51. One shaft end of the discharge auger 52 and one of the pulleys 68 are transmitted through a transmission structure. The transmission structure is two gears, that is, a gear is fixedly installed on the shaft end of the discharge auger 52 and the shaft end of the pulley 68, and the two gears are meshed with each other to realize the rotation drive of the discharge auger 52, wherein a plurality of notches 53 are also provided on the side of the semicircular tube 51, and a conveying unit 7 located below the semicircular tube 51 is provided on the inner side of the shovel arm 21. Preferably, the conveying unit 7 described in this embodiment can also be a conveyor belt driven by a motor and a roller. In addition, a fan 71 is also installed above the shovel arm 21 in the present invention, and the fan 71 faces the conveying unit 7 to cool down the fine particles transported outward to ensure the temperature of the particle pollutants discharged outward.

[0065] That is, the crushed fine particles move upward under the lifting of the conveyor belt 69 until the conveyor belt 69 is lifted to the above-mentioned semicircular tube 51, and the unloading auger 52 located inside the semicircular tube 51 rotates to feed the material. Since a plurality of notches 53 are provided on the outer side of the semicircular tube 51, the fine particles will fall through the notches 53 during the transfer process, and finally fall into the upper side of the conveying unit 7, and are continuously sent out by the conveying unit 7.

[0066] Reference Fig.11 In addition, in the embodiment of the present invention, the unloading mechanism 4 includes a silo 41 fixed to the frame 1 and fixed to the lifting frame 31, the silo 41 is located at the side of the discharge port 35, a silo cover 42 is rotatably connected to the bottom of the silo 41, and a spring 43 is fixedly connected between the silo cover 42 and the silo 41;

[0067] The side of the silo 41 is rotatably connected to a hook rod 45 via a bracket 44, and the hook rod 45 is also fixed to the bracket 44 by magnetic attraction. That is to say, in this embodiment, magnets are embedded on the upper side of the bracket 44 and the upper side of the hook rod 45, and the two magnets are magnetically attracted to each other. A protrusion 46 that is snap-fitted with the hook rod 45 is also provided on the side of the silo cover 42.

[0068] During actual operation, under the lifting of the conveyor belt 33, the block pollutants are sent outward along the discharge port 35 and finally fall into the silo 41. Since the bottom of the silo 41 is hooked by the hook rod 45 in the initial state, it has a storage capacity of a certain weight. When the weight of the stored pollutants is greater than the magnetic suction force, the hook rod 45 rotates and the entire silo cover 42 opens to discharge the pollutants stored in the silo 41 in piles for subsequent centralized collection. When the unloading is completed, the silo cover 42 is reset under the action of the spring 43 until the hook rod 45 is clamped on the outer side of the protrusion 46 to achieve fixation. Furthermore, in this embodiment, the ends of the hook rod 45 and the protrusion 46 are provided with abutment slopes.

[0069] In addition, the present invention also proposes a method for treating mine pollutants, which uses the above-mentioned device. The specific treatment method includes the following steps:

[0070] S1, the traveling frame 1 collects the solid waste through the scraper mechanism 2;

[0071] S2, the waste scraped by the scraping mechanism 2 is transported to the lifting and separation mechanism 3, and the block solid matter and the granular solid matter are screened by the lifting and separation mechanism 3;

[0072] S3, the block solid matter enters the unloading mechanism 4 and is discharged in a pile, and the granular solid matter enters the slag unloading mechanism 5, is embrittled and crushed, and is then discharged.

[0073] In summary, the lifting and separation mechanism 3 adopted in the present invention can realize differentiated treatment of the pollutants collected by the scraper mechanism 2. The block pollutants are processed by the unloading mechanism 4 and discharged in piles for subsequent centralized treatment, while the particulate pollutants enter the slag unloading mechanism 5, are brittle and crushed in the slag unloading mechanism 5 and then discharged, thereby ensuring the treatment effect of the particulate pollutants and improving the protection of the environment.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
