Description
Technical Field
[0001] This utility model relates to the field of coal gangue decarbonization technology, specifically to a coal gangue decarbonization device. Background Technology
[0002] Coal gangue is a solid waste generated during coal mining and washing. It is a type of blackish-gray rock with a low carbon content and harder than coal, which is associated with coal seams during coal formation. It includes gangue from tunnel excavation, gangue extracted from the roof, floor, and interlayers during mining, and gangue removed during coal washing. To utilize coal gangue as solid waste, decarbonization treatment is usually required.
[0003] In existing technologies, a decarbonization box is typically used to decarbonize coal gangue. The coal gangue enters the box and moves along a guide structure, coming into contact with high-temperature gas within the box, where it is decarbonized. However, in this type of decarbonization box, the coal gangue moves too quickly within the box, resulting in insufficient contact time between the coal gangue and the high-temperature gas, thus affecting the decarbonization effect.

Detailed Implementation
[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] This utility model provides a coal gangue decarbonization device that can improve the decarbonization efficiency of coal gangue.
[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.
[0025] See Figure 1 , Figure 4 As shown, the coal gangue decarbonization device provided in this embodiment includes a decarbonization box 1, a material guiding structure 6, and a synchronous reversing mechanism 5. The upper end of the decarbonization box 1 is provided with a feeding channel 2, the side of the decarbonization box 1 is connected with a guide pipe 3, and the lower end of the decarbonization box 1 is hinged with a carbon residue separation plate 4. The material guiding structure 6 is located inside the decarbonization box 1. The material guiding structure 6 includes a first guide plate 61 and a second guide plate 62, which are hinged together. The synchronous reversing mechanism 5 is installed on the decarbonization box 1 and is connected to the material guiding structure 6 to drive the material guiding structure 6 to be arranged in a positive V-shape or an inverted V-shape.
[0026] In the process of preparing for decarbonization of coal gangue, the synchronous reversing mechanism 5 drives the guiding structure 6 to be arranged in a positive V-shape. The coal gangue then enters the decarbonization chamber 1 through the feeding channel 2 and piles onto the positive V-shaped guiding structure 6. High-temperature gas enters the decarbonization chamber 1 from the guide pipe 3 and contacts the coal gangue for a specified time to perform relatively thorough decarbonization, achieving a better decarbonization effect. After decarbonization, the synchronous reversing mechanism 5 drives the guiding structure 6 to switch from a positive V-shape to an inverted V-shape. In the V-shaped structure, the decarbonized coal gangue, along with the carbon residue separated from the coal gangue, slides down onto the carbon residue separation plate 4. It then falls through the separation holes on the carbon residue separation plate 4 onto the carbon residue receiving plate (not shown in the figure). The carbon residue receiving plate is then removed, and the carbon residue separation plate 4 is opened to allow the decarbonized coal gangue to drain from the decarbonization box 1. The carbon residue separation plate 4 can be connected to a vibrator. During the separation of carbon residue, the vibrator drives the carbon residue separation plate 4 to vibrate, thereby achieving more thorough separation of carbon residue.
[0027] In addition, the first and second guide plates can be arranged in a V-shape or an inverted V-shape, or other shapes suitable for placement inside the decarbonization box. Specific shapes include, but are not limited to: a U-shaped structure, in which coal gangue is piled up at the bottom of the U-shaped structure; and an M-shaped structure, which can be arranged in an M-shaped structure or an inverted M-shaped structure, in which coal gangue is piled up in the recessed part of the M-shaped structure.
[0028] This utility model provides a coal gangue decarbonization device. Coal gangue enters the decarbonization chamber through the feeding channel and then enters the guiding structure. The first and second guiding plates in the guiding structure are arranged in a positive V-shape by a synchronous reversing mechanism. The coal gangue accumulates at the bottom of the V-shape. At the same time, the guide pipe is opened to allow high-temperature gas to enter the decarbonization chamber for decarbonization treatment of the coal gangue. After the treatment is completed, the first and second guiding plates are arranged in an inverted V-shape by the synchronous reversing mechanism, and the treated coal gangue is poured onto the carbon residue separation plate for recycling, thereby improving the overall decarbonization effect of the coal gangue.
[0029] See Figure 2 , Figure 3 , Figure 4 and Figure 6In some embodiments, shafts 64 are fixedly connected to both sides of the first end of the first guide plate 61, and bushings 63 are fixedly connected to both sides of the first end of the second guide plate 62, with the shafts 64 passing through the bushings 63. The bushings 63 on both sides of the first end of the second guide plate 62 are supported in the support holes on the two opposite side plates of the decarbonization box 1, and can rotate relative to the support holes. The shafts fixedly connected to the first side of the first end of the first guide plate and the bushings on the first side of the first end of the second guide plate both extend out of the decarbonization box. In this way, the shafts are located in the first guide plate to fix the position of the guide plate and prevent the position of the guide plate from shifting. The purpose of installing bushings on the second guide plate is to reduce the friction between the shafts and the decarbonization box, and at the same time to prevent the shafts from shifting direction due to vibration or other reasons during movement.
[0030] See Figure 4 In some embodiments, the first end of the second guide plate 62 has a notch, and the first end of the first guide plate 61 is embedded in the notch of the second guide plate 62; in this way, when the first guide plate and the second guide plate are arranged in a V-shape, the first guide plate abuts against the notch of the second guide plate to limit the movement and prevent the first guide plate and the second guide plate from closing together.
[0031] See Figure 4 In some embodiments, both the first guide plate 61 and the second guide plate 62 are provided with ventilation holes (not shown in the figure, the same below), and the inner diameter of the ventilation holes is smaller than the particle size of the coal gangue; wherein, the high temperature gas can be in more complete contact with the coal gangue particles accumulated on the first guide plate 61 and the second guide plate 62 through the ventilation holes; the gas pressure of the high temperature gas can also, to a certain extent, suspend or agitate the coal gangue particles accumulated on the first guide plate 61 and the second guide plate 62; in addition, the carbon residue formed during the decarburization process can also fall to the carbon residue separation plate 4 through the ventilation holes, and can fall to the carbon residue receiving plate through the separation holes on the carbon residue separation plate 4.
[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 5In some embodiments, the synchronous reversing mechanism 5 includes a worm gear box 51, a motor 52, a first worm 53, a first worm wheel 54, a second worm 56, and a second worm wheel 57. The worm gear box 51 is fixed to the outside of the decarbonization chamber 1, the motor 52 is fixed to the worm gear box 51, the first worm wheel 54 is fixed to the shaft 64 extending out of the decarbonization chamber, and the second worm wheel 57 is fixed to the bushing 53 extending out of the decarbonization chamber. The two ends of the first worm and the second worm are rotatably connected to the side plate of the worm gear box through bearings. The first worm 53 is driven by the first worm wheel 54, and the second worm 56 is driven by the second worm wheel 57. The first ends of the first worm 53 and the second worm 56 both penetrate one side wall of the worm gear box 1 and are respectively fixedly connected to a first gear 55 and a second gear 58. The first gear 55 and the second gear 58 mesh with each other. The output shaft of the motor 52 is fixedly connected to the end of the first worm 53 away from the first gear 55. Thus, the motor 52 drives the first worm 53 to rotate, which in turn drives the first gear 55 to rotate. As the first gear 55 and the second gear 58 mesh, the second gear 58 rotates in a synchronous reverse direction. This causes the second gear 58 to drive the second worm 56 to rotate simultaneously. Since the first worm 53 and the second worm 56 rotate in opposite directions, the transmission between the first worm 53 and the first worm wheel 54, and the transmission between the second worm 56 and the second worm wheel 57, causes the two worm wheels 54 and 57 to rotate in opposite directions. The first worm wheels 54 and 57 then drive the shaft 64 and the bushing 63 to rotate in a synchronous reverse direction, thereby driving the first guide plate 61 and the second guide plate 62 to move in a synchronous reverse direction. This adjusts the first guide plate 61 and the second guide plate 62 into a positive V-shaped arrangement. The motor 52 rotates in the reverse direction, and according to the above transmission relationship, the first guide plate 61 and the second guide plate 62 can be adjusted into an inverted V-shaped arrangement.
[0033] See Figure 1 , Figure 3 , Figure 5In some embodiments, the second gear 58 on the bottom surface of the decarbonization chamber 1 is also equipped with a locking mechanism 7. The locking mechanism 7 includes a receiving seat 71, a slider 72, a toothed block 73, an electromagnet 74, and a spring 75. The receiving seat 71 is fixedly connected to the decarbonization chamber 1, the slider 72 is slidably connected inside the receiving seat 71, the electromagnet 74 is fixed in the receiving seat 71, and the slider 72 is attracted to the electromagnet 74 when the electromagnet 74 is energized. The spring 75 is located outside the electromagnet 74 and is connected between the slider 72 and the receiving seat 71. The toothed block 73 is fixed on the surface of the slider 72 and meshes with the second gear 58. When it is necessary to lock the worm to prevent it from rotating, the current to the electromagnet 74 is disconnected. At this time, the compressed spring 75 pushes the slider 72 out of the storage seat 71. Then, the slider 72 drives the tooth block 73 to mesh with the second gear 58 to lock the wheel, thereby locking the first worm 53 and the second worm 56 to prevent the worm from rotating. When unlocking, the electromagnet 74 is energized. The electromagnet 74 is connected to an external power switch. The electromagnet 74 attracts the slider 72 and moves it into the storage seat 71 and squeezes the spring 75. This can drive the tooth block 73 to separate from the second gear 58, thereby unlocking the worm.
