[0029] An embodiment of the present application discloses a coal blending control device.

[0030] Referring to Figures 1-4 , a coal blending control device includes a coal blending box 1, a coal inlet pipe 2, a plurality of coal blending mechanisms 3, and a mixing assembly 4 are provided on the coal blending box 1. The coal inlet pipe 2 is connected to the top side wall of the coal blending box 1 in a communicating manner, the plurality of coal blending mechanisms 3 are connected to the periphery of the coal blending box 1 in a communicating manner, and the mixing assembly 4 is rotatably arranged in the coal blending box 1;

[0031] The coal blending mechanism 3 includes a feeding assembly 31 and an extrusion assembly 33. The feeding assembly 31 is communicated with the upper end of the extrusion assembly 33, and the other end of the extrusion assembly 33 is communicated with the coal blending box 1;

[0032] During use, ordinary coal is fed into the coal blending box 1 through the coal inlet pipe 2, dispersed and discharged from the bottom. When it is necessary to proportion ordinary coal to achieve the combustion quality of the boiler, high-quality coal can be added from the side coal blending mechanism 3. The high-quality coal is weighed and calculated in the feeding assembly 31. After reaching a certain amount, the high-quality coal is discharged through the feeding assembly 31, so that the high-quality coal is discharged into the extrusion assembly 33 and then discharged into the coal blending box 1 through the extrusion assembly 33. Through the setting of the mixing assembly 4, the ordinary coal and the high-quality coal are dispersed and mixed, so that the coal fed into the boiler reaches a certain quality. Through the coal blending mechanism 3, various qualities of coal can be accurately weighed and then discharged into the coal blending box 1 to be mixed and proportioned with ordinary fuel coal under the action of the mixing assembly 4, making the proportioning of the fuel coal more accurate, the proportioning efficiency higher, and reducing the labor cost.

[0033] Referring to Figures 1-3, the blanking assembly 31 includes a blanking hopper 311, a weighing plate 312 and a driving assembly 32. The weighing plate 312 is rotatably arranged in the blanking hopper 311. The driving assembly 32 is fixedly arranged on the outer wall of the blanking hopper 311, and the driving assembly 32 drives the weighing plate 312 to rotate. In this embodiment, the weighing plate 312 is equipped with an electronic gravity sensor scale, which can weigh and measure the coal material. During use, high-quality coal material is poured into the blanking hopper 311 from the feeding end. The weighing plate 312 weighs the coal material. When the required weight is reached, the driving assembly 32 drives the weighing plate 312 to tilt downward, so that the coal material slides down along the weighing plate 312 and is discharged into the extrusion assembly 33 through the blanking hopper 311. Through the setting of the weighing plate 312, the high-quality coal material can be weighed and then put into the coal blending box 1 for coal material proportioning, ensuring the proportioning quality of the coal material.

[0034] Refer to Figure 3 , the driving assembly 32 includes a first motor 321, a transmission gear set 322 and a housing 323. The first motor 321 is fixedly arranged on the side wall of the blanking hopper 311. One end of the transmission gear set 322 is connected to the first motor 321, and the other end of the transmission gear set 322 is connected to the rotating end of the weighing plate 312. The housing 323 covers the rotating gear set. During use, the first motor 321 drives the transmission gear set 322 to rotate. Through the setting of the transmission gear set 322, the degree of flipping of the weighing plate 312 in the blanking hopper 311 can be effectively driven, and at the same time, the opening and closing state of the blanking hopper 311 can be controlled through the weighing plate 312.

[0035] Refer to Figure 2 , the extrusion assembly 33 includes an extrusion pipe 331, a spiral extrusion rod 332 and a second motor 333. The spiral extrusion rod 332 is rotatably arranged in the extrusion pipe 331, and the second motor 333 drives the spiral extrusion rod 332 to rotate;

[0036] During use, the second motor 333 drives the spiral extrusion rod 332 to rotate in the extrusion pipe 331, which can effectively discharge the high-quality coal material falling from the blanking hopper 311 into the extrusion pipe 331 into the coal blending box 1 for mixing with ordinary coal material. At the same time, the setting of the spiral extrusion rod 332 can effectively prevent the phenomenon of blockage in the extrusion pipe 331.

[0037] Refer to Figure 2 , a blower 313 is also arranged on the side wall of the blanking hopper 311. A downward air guide plate 314 is fixedly arranged at the air outlet end of the blower 313. Through the setting of the blower 313, the high-quality coal material can be quickly dropped from the weighing plate 312 into the extrusion assembly 33. At the same time, it can prevent the flue gas in the boiler from blowing back in the opposite direction when the high-quality coal material is discharged on the inclined weighing plate 312, causing the high-quality coal material to flow back. At the same time, the setting of the air guide plate 314 can effectively prevent the coal material from entering the blower 313.

[0038] Refer to Figure 2 , the mixing component 4 includes a third motor 41, a rotating rod 42, a dispersing rod 43 and a mixing disc 44. The third motor 41 drives the rotating rod 42 to rotate. The rotating rod 42 is rotatably installed at the top of the coal blending box 1. The dispersing rod 43 is fixedly arranged at the lower end of the rotating rod 42. The mixing disc 44 is fixedly arranged at the bottom end of the rotating rod 42;

[0039] During use, the third motor 41 drives the rotating rod 42 to rotate, driving the dispersing rod 43 and the mixing disc 44 to rotate. Through the arrangement of the dispersing rod 43, ordinary coal materials and high-quality coal materials can be effectively dispersed and mixed. At the same time, the mixing disc 44 below further mixes the ordinary coal materials and high-quality coal materials.

[0040] Refer to Figure 4 , a plurality of material discharging grooves are formed on the mixing disc 44, and a plurality of convex strips are fixedly arranged on the mixing disc 44. Through the arrangement of the material discharging grooves, the continuous supply of coal materials during mixing can be ensured, and at the same time, the blockage of coal materials at the discharging end of the coal blending box 1 can be prevented. By arranging convex strips on the mixing disc 44, the mixing effect of coal materials can be better ensured.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
