Description

Technical Field

[0001] The utility model relates to the technical field of coal material processing equipment, in particular to a coal blending and mixing device. Background Art

[0002] Coal coking is also known as coal high-temperature dry distillation. It is a coal conversion process that uses coal as raw material, heats it to about 950℃ under air-tight conditions, and produces coke through high-temperature dry distillation, while obtaining coal gas, coal tar, and recovering other chemical products.

[0003] At present, in the overall operation process of coal coking, usually multiple types of coal are mixed for coking. Before the coal is transported to the coke oven for coking, it is necessary to crush the coal and mix the crushed multiple types of coal to ensure the product quality of coal coking.

[0004] However, in the existing coal crushing and mixing equipment, a mixer is generally used to mix the crushed coal. The mixing capacity of the mixer is limited, and the mixing capacity is prone to decrease or even shutdown due to failure during continuous operation. The frequency of shutdown for maintenance is high and the stability is poor, which greatly reduces the operating efficiency of coal coking. Utility Model Content

[0005] The problem solved by the utility model is how to improve the stability of the coal mixing process while ensuring the quality of coal mixing, so as to ensure the operating efficiency of coal coking.

[0006] In order to solve the above problems, the utility model provides a coal blending and mixing device, including a coal blending mechanism, a crushing mechanism and a coal mixing mechanism, the coal mixing mechanism including a coal mixing belt and a coal mixing chute, the coal blending mechanism is connected to the input end of the crushing mechanism, the two ends of the coal mixing belt are respectively connected to the output end of the crushing mechanism and the input end of the coal mixing chute, the cross-sectional size of the output end of the coal mixing chute tends to decrease along the output direction, the coal blending mechanism is used to receive coal and transmit it to the crushing mechanism, and the crushing mechanism is used to crush the coal and transmit it to the coal mixing belt.

[0007] Compared with the prior art, the beneficial effects of the utility model include: a coal blending mechanism, a crushing mechanism and a coal mixing mechanism are set up to form a coal blending and mixing device, the coal blending mechanism can receive a variety of coal materials to be distributed, and transfer the coal materials to the crusher for crushing, and after the coal materials in the crushing mechanism are crushed, they can be transferred to the coal mixing mechanism for mixing, thereby completing the coal blending and mixing. Specifically, a coal mixing belt and a coal mixing chute are arranged to form a coal mixing mechanism, and the two ends of the coal mixing belt are respectively connected to the output end of the crushing mechanism and the input end of the coal mixing chute. After the crushing mechanism completes the coal crushing and outputs the coal, the crushed coal will fall on the coal mixing belt, and the coal mixing belt can convey the coal to the coal mixing chute. When the coal mixing belt is conveying, the rotation of the conveying roller will drive the conveying surface of the coal mixing belt to vibrate. During the shaking of the conveying surface, the crushed coal will slightly jump on the conveying surface, causing the coal to move irregularly on the conveying surface, thereby causing the various crushed coals conveyed on the coal mixing belt to mix, effectively improving the mixing effect of the coal. On this basis, the cross-sectional size of the output end of the coal mixing chute tends to decrease along the output direction, and the crushed coal on the coal mixing belt passes through the input end of the coal mixing chute. When input and output through the output end, the crushed coal moves along the inner wall of the output end of the mixed coal chute. Due to the change in the cross-sectional size of the output end of the mixed coal chute, the crushed coal on its inner wall is squeezed close to each other and move relative to each other, thereby mixing the various crushed coals output, further improving the mixing effect of the coal, and effectively ensuring the mixing quality of the coal transmitted to the coal tower waiting to be transported to the coke oven for coking. Moreover, the structure composed of a mixed coal belt and a mixed coal chute is used to replace the existing mixer for coal mixing, and the stable transmission of the mixed coal belt can be used to ensure the continuity of coal mixing.

[0027] In this embodiment, if Figure 1As shown, a coal blending mechanism 1, a crushing mechanism 2 and a coal mixing mechanism 3 are provided to form a coal blending and mixing device. The coal blending mechanism 1 can receive a variety of coal materials to be distributed, and transfer the coal materials to the crushing mechanism 2 for crushing. After the coal materials in the crushing mechanism 2 are crushed, they can be transferred to the coal mixing mechanism 3 for mixing, thereby completing the coal blending and mixing. Specifically, a coal mixing belt 31 and a coal mixing chute 32 are provided to form a coal mixing mechanism 3, and the two ends of the coal mixing belt 31 are respectively connected to the output end of the crushing mechanism 2 and the input end of the coal mixing chute 32. After the crushing mechanism 2 completes the coal crushing and outputs the coal, the crushed coal will fall on the coal mixing belt 31, and the coal mixing belt 31 can convey the coal to the coal mixing chute 32. When the coal mixing belt 31 is conveying, the rotation of the conveying roller will drive the conveying surface of the coal mixing belt 31 to vibrate. During the shaking of the conveying surface, the crushed coal will slightly jump on the conveying surface, causing the coal to move irregularly on the conveying surface, thereby causing the various crushed coals conveyed on the coal mixing belt 31 to mix, effectively improving the mixing effect of the coal. On this basis, the cross-sectional size of the output end of the coal mixing chute 32 tends to decrease along the output direction, and the crushed coal on the coal mixing belt 31 passes through the coal mixing chute When the coal is input through the input end of 32 and output through the output end, the crushed coal moves along the inner wall of the output end of the mixing coal chute 32. Due to the change in the cross-sectional size of the output end of the mixing coal chute 32, the crushed coal on its inner wall is squeezed close to each other and move relative to each other, thereby mixing the various crushed coals output, further improving the mixing effect of the coal, and effectively ensuring the mixing quality of the coal transmitted to the coal tower waiting to be transported to the coke oven for coking. Moreover, the structure composed of the mixing coal belt 31 and the mixing coal chute 32 replaces the existing mixer 33 for coal mixing, and the stable transmission of the mixing coal belt 31 can be used to ensure the continuity of coal mixing. The structure of the mixing coal belt 31 and the mixing coal chute 32 is relatively simple, and the use stability is high. Even if an operating failure occurs, it is easy to repair and replace, which can effectively improve the stability of the coal mixing process, thereby ensuring the operating efficiency of coal coking.

[0028] In this embodiment, if Figure 1 As shown, in order to further ensure the stability during the coal mixing process, a spare coal mixing mechanism 3 is also provided, wherein the spare coal mixing mechanism 3 may be a structure composed of a coal mixing belt 31 and a coal mixing chute 32, or an existing mixer 33 may be used as the spare coal mixing mechanism 3, thereby facilitating the arrangement of a new coal blending and mixing production line, and facilitating the improvement of the existing coal blending and mixing production line, thereby effectively improving the application scope and convenience of the coal blending and mixing device.

[0029] It should be noted that, in the present invention, the coal mixing belt 31 is a belt conveyor.

[0030] Optionally, the coal blending and mixing device further includes a first transmission mechanism 4 , and the output end of the pulverizing mechanism 2 transmits the coal material to the coal mixing belt 31 through the first transmission mechanism 4 , and the first transmission mechanism 4 includes at least one first transmission belt 41 .

[0031] In this embodiment, in order to further improve the mixing effect of the crushed coal, Figure 1 As shown, a first transmission mechanism 4 is also provided, wherein the output end of the crushing mechanism 2 can transmit the coal to the coal mixing belt 31 through the first transmission mechanism 4, and the first transmission mechanism 4 includes at least one first transmission belt 41. In this way, after the crushed coal is output through the output end of the crushing mechanism 2, the first transmission mechanism 4 can transmit the crushed coal through the first transmission belt 41, thereby utilizing the shaking of the conveying surface of the first transmission belt 41 to enhance the mixing effect of the crushed coal, and finally transmit it to the coal mixing belt 31 for further mixing of the coal, thereby effectively ensuring the mixing quality of the coal.

[0032] It should be noted that, in this embodiment, Figure 1 As shown, there are two first transmission belts 41, one first transmission belt 41 can receive the crushed coal outputted from the output end of the crushing mechanism 2, and a first head chute 42 is provided between the two first transmission belts 41, and the crushed coal can be transmitted to the other first transmission belt 41 through the first head chute 42, and the other first transmission belt 41 can transmit the crushed coal to the mixed coal belt 31 through the second head chute 43, thereby ensuring the stable transmission of the coal and further improving the mixing quality of the coal. Of course, in other embodiments of the utility model, only one first transmission belt 41 and one second head chute 43 can be provided, or one second head chute 43, more than two first transmission belts 41 and at least two first head chutes 42 can be provided.

[0033] It should be noted that, in this embodiment, if a spare coal mixing mechanism 3 is set up, the second head chute 43 arranged between the first transmission belt 41 and the coal mixing mechanism 3 is a head fork chute, which can receive the coal transmitted by the first transmission belt 41 and transmit it to the two coal mixing mechanisms 3 in two ways to ensure the continuity of the coal blending and mixing device.

[0034] It should be noted that, in the present invention, the first transmission belt 41 is a belt conveyor.

[0035] Optionally, the coal blending and mixing device also includes a second transmission mechanism 5 and a coal tower feeder 6. The output end of the mixed coal chute 32 transmits coal to the coal tower feeder 6 through the second transmission mechanism 5. The coal tower feeder 6 is used to transmit coal to the coal tower. The second transmission mechanism 5 includes at least one second transmission belt 51.

[0036] In this embodiment, in order to further improve the mixing effect of the crushed coal, Figure 1 As shown, a second transmission mechanism 5 and a coal tower feeder 6 are also provided, wherein the output end of the mixed coal chute 32 can transmit the coal to the coal tower feeder 6 through the second transmission mechanism 5, so that the coal tower feeder 6 can receive the mixed crushed coal and transmit it to the coal tower, waiting for the staff to transport the coal in the coal tower to the coke oven for coal coking operations, and the second transmission mechanism 5 includes at least one second transmission belt 51. In this way, after the crushed coal is output through the output end of the mixed coal chute 32, the second transmission mechanism 5 can transmit the crushed coal through the second transmission belt 51, thereby utilizing the shaking of the conveying surface of the second transmission belt 51 to improve the mixing effect of the crushed coal, thereby effectively ensuring the mixing quality of the coal.

[0037] It should be noted that, in this embodiment, Figure 1 As shown, there are two second transmission belts 51, one second transmission belt 51 can receive the crushed coal outputted from the output end of the coal mixing chute 32, and a third head chute 52 is provided between the two second transmission belts 51, and the crushed coal can be transmitted to another second transmission belt 51 through the third head chute 52, and another second transmission belt 51 can transmit the crushed coal to the coal tower feeder 6, thereby ensuring the stable transmission of the coal and further improving the mixing quality of the coal. Of course, in other embodiments of the utility model, only one second transmission belt 51 can be provided, or more than two second transmission belts 51 and at least two third head chutes 52 can be provided.

[0038] It should be noted that, in the present invention, the second transmission belt 51 is a belt conveyor.

[0039] Optionally, the coal tower distribution machine 6 includes a machine body and a distribution belt, wherein the distribution belt is located inside the machine body, and the distribution belt is used to receive the coal transmitted by the second transmission mechanism 5 and transmit it to the coal tower.

[0040] In this embodiment, in order to further improve the mixing effect of the crushed coal, a machine body and a distribution belt are provided to form a coal tower distribution machine 6, wherein the distribution belt is located inside the machine body, so that it can receive the coal transmitted by the second transmission mechanism 5, and finally transmit it to the coal tower. In the process of the coal transmission by the distribution belt, the shaking of the conveying surface can be used to further mix the crushed coal, effectively improving the mixing effect of the crushed coal, further ensuring the mixing quality of the coal and the subsequent coal coking effect.

[0041] It should be noted that, in this embodiment, two first transmission belts 41, two second transmission belts 51, one coal mixing belt 31 and one material distribution belt, a total of six belt conveyors, are provided for mixing the crushed coal. After testing the coal mixing effect by adding sawdust to the coal, the following results are obtained: Figure 5 The comparison chart of the effect of mixed coal is shown in Figure 5 From the table, it can be seen that after the coal is mixed by belt vibration, the data corresponding to No. 0 is the predicted value of the coal blending ratio of the mixer, and the mean value of the data after the coal is mixed from No. 1 to No. 16 is approximately equal to the predicted value of the coal blending ratio or is within its range, that is, the mixing quality of the coal after mixing by six belt conveyors can reach the mixing quality after mixing by the existing mixer, which can effectively ensure the production quality of coal coking.

[0042] Optionally, the mixed coal chute 32 includes an input shell 321 and an output shell 322. The input shell 321 is located on one side of the output end of the mixed coal belt 31, and the opening is U-shaped toward the mixed coal belt 31. The output shell 322 is arranged below the input shell 321, and is a hollow structure with upper and lower openings. The opening cross-sectional size of the output shell 322 gradually decreases from top to bottom.

[0043] In this embodiment, in order to ensure the mixing effect of coal, Figure 2 As shown, an input shell 321 and an output shell 322 are provided to form a mixed coal chute 32, wherein the input shell 321 is located at one side of the output end of the mixed coal belt 31, and the opening is arranged in a U shape toward the mixed coal belt 31, so that during the operation of the mixed coal belt 31, the crushed coal on the conveying surface at the output end can collide with the side wall plate of the input shell 321 under the action of inertia, and the side wall plate of the input shell 321 can limit the coal to prevent the coal from flying out of the production line. At the same time, after the collision, the coal moves irregularly in the reverse direction, which can further improve the mixing effect of the coal. On this basis, the output shell 322 is arranged below the input shell 321, and is a hollow structure with upper and lower openings, and the output shell 32 2 gradually decreases from top to bottom. With this arrangement, after the coal hits the wall plate of the input shell 321, under the subsequent extrusion of the coal, there is a tendency to move along the circumferential direction of the wall plate of the input shell 321, and at the same time, it will move downward into the output shell 322 under the action of gravity, thereby moving downward in a spiral along the inner wall plate of the output shell 322, which can effectively increase the moving distance of the coal in the output shell 322. At the same time, since the opening cross-sectional size of the output shell 322 gradually decreases from top to bottom, the coal is fully mixed during the movement, effectively improving the mixing effect of the crushed coal, and further ensuring the mixing quality of the coal and the subsequent coal coking effect.

[0044] It should be noted that, in this embodiment, the output shell 322 is a chute structure.

[0045] Optionally, the coal blending and mixing device also includes a material baffle mechanism 7, which includes a material baffle plate 71. The material baffle plate 71 is arranged in the input shell 321 and above the output shell 322. The projection of the material baffle plate 71 on the upper opening end surface of the output shell 322 is a curve that is recessed away from the coal mixing belt 31.

[0046] In this embodiment, if Figure 2 As shown, a baffle mechanism 7 is also provided, wherein the baffle mechanism 7 includes a baffle plate 71, and the baffle plate 71 is arranged in the input shell 321 and above the output shell 322. When the coal is transmitted to the input shell 321 through the coal mixing belt 31, it can hit the baffle plate 71 and finally fall into the output shell 322. At the same time, the projection of the baffle plate 71 on the upper open end face of the output shell 322 is a curve that is recessed away from the coal mixing belt 31, that is, the baffle plate 71 is a curved surface structure with an opening facing the coal mixing belt 31. When the coal on the coal mixing belt 31 continuously hits the baffle plate 71, under the extrusion of the coal, the coal moves along the arc surface of the baffle plate 71, thereby causing the coal to move circumferentially and move downward at the same time to form a spiral moving path, and finally further mixing is achieved during the movement, effectively improving the mixing effect of the crushed coal, further ensuring the mixing quality of the coal and the subsequent coal coking effect.

[0047] It should be noted that if Figure 3 As shown, two baffle plates 71 are provided, and the two baffle plates 71 are connected, and the connection corresponds to the middle position of the coal mixing belt 31, so that after the coal enters the input shell 321, it is divided into two streams through the connection of the two baffle plates 71, and both move in a spiral shape along the baffle plates 71, and finally converge on the wall plate of the output shell 322, and then further mixed, which effectively improves the mixing effect of the crushed coal, further ensures the mixing quality of the coal and the subsequent coal coking effect.

[0048] Optionally, the material blocking mechanism 7 also includes an adjusting component 72, which includes an adjusting rod 721 and an adjusting seat 722. The adjusting seat 722 is installed on the mixed coal chute 32 and is located on the side of the material blocking plate 71 away from the mixed coal belt 31. One end of the adjusting rod 721 is connected to the material blocking plate 71, and the other end of the adjusting rod 721 is detachably mounted on the adjusting seat 722 and is used to reciprocate along the adjusting seat 722 to drive the material blocking plate 71 to move toward or away from the mixed coal belt 31.

On this basis, the other end of the adjustment rod 721 can be detachably installed on the adjustment seat 722, and after the position of the material blocking plate 71 is adjusted, the position stability of the material blocking plate 71 can be ensured by connecting the adjustment rod 721 with the adjustment seat 722, thereby ensuring the stability of the coal blending and mixing process.

[0050] It should be noted that, in this embodiment, Figure 4 As shown, the adjusting rod 721 is provided with a plurality of adjusting holes, and the adjusting seat 722 is provided with a positioning hole. By aligning the adjusting holes and the positioning holes and inserting the positioning pins, the position of the adjusting rod 721 can be fixed, thereby achieving the position of the baffle plate 71 to be fixed.

[0051] Optionally, the adjustment assembly 72 also includes a support rod 723 and a support seat 724. The support rod 723 is located above the baffle plate 71 and connected to the baffle plate 71. The support seat 724 is installed on the mixed coal chute 32. A plurality of support grooves 7241 with openings facing upward are arranged on the support seat 724 at intervals along the moving direction of the baffle plate 71. The end of the support rod 723 is supported in the support groove 7241, and the end of the adjustment rod 721 is hinged to the baffle plate 71.

[0052] In this embodiment, if Figures 2 to 4 As shown, in order to ensure the stability of the baffle plate 71, the adjustment assembly 72 is further provided with a support rod 723 and a support seat 724, wherein the support rod 723 is located above the baffle plate 71 and connected to the baffle plate 71, and the support seat 724 is installed on the mixed coal chute 32, and a plurality of support grooves 7241 with openings upward are arranged at intervals along the moving direction of the baffle plate 71, and the end of the support rod 723 is supported in the support groove 7241, so that the support rod 723 is supported by the support seat 724. Finally, the baffle plate 71 is supported to ensure the stability of the baffle plate 71. At the same time, the end of the adjusting rod 721 is hinged to the baffle plate 71, so that when the position of the baffle plate 71 is adjusted, the baffle plate 71 is first lifted upward by the adjusting rod 721 to move the support rod 723 out of the support groove 7241, and then the baffle plate 71 is pushed to make the end of the support rod 723 move along the support seat 724 and finally fall into the corresponding support groove 7241, thereby achieving stable adjustment of the baffle plate 71.
