Technical Field

[0001] The invention relates to the technical field of fuel for thermal power plants, and in particular to a conveying device and method for treating fuel for thermal power plants. Background Art

[0002] Thermal power plant fuel generally refers to the fuel required for thermal power plants to produce electricity. The power generation fuel of thermal power plants is roughly divided into solid fuel, liquid fuel, and gas fuel according to their form. Solid fuel is mainly coal. The components of coal include carbon, ash, water and volatiles. Coal is a combustible black or brown-black sedimentary rock, which usually occurs in rock strata or veins of coal beds or coal seams. Coal is mainly composed of carbon, oxygen, nitrogen, sulfur and phosphorus. It mainly produces electricity or heat energy through combustion; it is also an important raw material for metallurgy and chemical industry. Thermal power generation is the main force of power development in modern society. In the direction of improving thermal power technology, we must focus on the impact of electricity on the environment and the impact on non-renewable energy. Although there are some nuclear power units in China, thermal power still occupies most of the power market. In recent years, the development of electricity has lagged behind economic development. Many thermal power plants have been built across the country, but thermal power technology must continue to improve and develop.

At the same time, one of the servo motors 1107 is started intermittently, and the winding disk 1108 is driven by the servo motor 1107 so that the rope two 1105 pulls the adjusting slide plate 1104 to slide outside the rope one 1103, so as to evenly perform dust reduction operations on the conveyor belt body 5.

[0045] Reference Figure 8 and Fig.10 Two through holes are provided on one side of the adjusting slide plate 1104, and the insides of the two through holes are surrounded by extrusion springs 12, and the other ends of the multiple extrusion springs 12 located on the same side are fixedly connected to the same U-shaped mounting frame 13, and circular holes thirteen are provided on both sides of the multiple U-shaped mounting frames 13 at equal distances, and the insides of the two opposite circular holes thirteen are connected with balls 14 through bearings.

[0046] In a specific application scenario, when the adjusting slide plate 1104 slides outside the rope 1103, the extrusion spring 12 uses its own elasticity to make the ball 14 on the U-shaped mounting frame 13 resist against the outer wall of the rope 1103, and the contact area between the ball 14 and the outside of the rope 1103 is small, thereby reducing the friction of the adjusting slide plate 1104 on the rope 1103 and increasing its service life.

[0047] A method for using a conveying device for treating fuel in a thermal power plant, using the conveying device for treating fuel in a thermal power plant as described above, comprising the following steps:

[0048] Step 1: When the conveyor belt body 5 is conveying fuel, the oblique roller 811 and the transverse roller 813 on the tooling transverse plate 809 support the conveyor belt body 5, so that the fuel on the conveyor belt body 5 is pressed down so that the conveyor belt body 5 is in a U shape to convey the fuel;

[0049] Step 2: The conveyor belt body 5 is limited by the limiting wheel 1 804 on the U-shaped limiting frame 1 803 and the limiting wheel 2 817 on the U-shaped limiting frame 2 816 distributed on the tooling transport frame 1 at the same time in the limiting position of the return spring 1 807 and the return spring 2 820;

[0050] Step three, during the fuel transportation process, the universal motor 829 is started, and the eccentric driving wheel 831 on the rotating circular plate 830 is driven by the universal motor 829 to move in the slide groove on the driving tooth plate 833, so that the tooth block end of the driving tooth plate 833 moves back and forth in an arc shape, so that the driving tooth plate 833 drives the linkage gear rod 825 to make the reciprocating impact slide column 824 reciprocate and rise and fall under the limit of the limit circular frame 823, so that the impact soft plate 828 on the reciprocating impact slide column 824 reciprocates and impacts the conveyor belt body 5.

[0051] Working principle: When the conveyor belt body 5 is conveying fuel, the oblique roller 811 and the transverse roller 813 on the tooling transverse plate 809 support the conveyor belt body 5, so that the fuel on the conveyor belt body 5 is pressed down so that the conveyor belt body 5 is in a U-shape to convey the fuel. At the same time, the limiting wheel 1 804 on the U-shaped limiting frame 1 803 and the limiting wheel 2 817 on the U-shaped limiting frame 2 816 distributed on the tooling transport frame 1 are limited by the limiting of the return spring 1 807 and the return spring 2 820. During the fuel conveying process, the universal motor 829 is started at this time, and the rotating circular plate 830 is driven by the universal motor 829. The eccentric driving wheel 831 on the driving tooth plate 833 moves in the slide groove on the driving tooth plate 833, so that the tooth block end of the driving tooth plate 833 moves back and forth in an arc shape, so that the driving tooth plate 833 drives the linkage tooth rod 825 to make the reciprocating impact slide column 824 reciprocate and rise and fall under the limit of the limit circle frame 823, so that the impact soft plate 828 on the reciprocating impact slide column 824 reciprocates to impact the conveyor belt body 5. When the fuel is transported through the conveyor belt body 5, water is pumped into the rotating circular tube 1110 through the water inlet hose 1112, and then the water is transported to the hollow slide seat 1118 through the delivery hose 1123 on the rotating circular tube 1110, so that The spray head 1117 on the hollow slide 1118 performs dust reduction operation on the dust generated by conveying fuel, and at the same time starts the speed regulating motor 1111, and drives the belt 1113 to rotate through the speed regulating motor 1111, so that the rotating tube 1110 drives the slide bar 1122 on the rotating seat 1121 to rotate, and drives the hollow slide 1118 to move in the limit track 1116 through the slide bar 1122. When the speed regulating motor 1111 continues to rotate, the slide bar 1122 slides in the slide hole on the rotating seat 1121, so that the limit track 1116 slides outside the guide cylinder 3 1114 through the slider 1115, so that the spray head 1118 117 is sprayed at multiple points on the conveyor belt body 5, and one of the servo motors 1107 is started intermittently at the same time. The servo motor 1107 drives the winding disk 1108 to make the rope 2 1105 pull the adjusting slide 1104 to slide outside the rope 1 1103, so as to evenly perform dust reduction operations on the conveyor belt body 5. When the adjusting slide 1104 slides outside the rope 1103, the extrusion spring 12 uses its own elasticity to make the ball 14 on the U-shaped mounting frame 13 resist against the outer wall of the rope 1103, and the contact area between the ball 14 and the outside of the rope 1103 is small, thereby reducing the friction of the adjusting slide 1104 on the rope 1103.

[0052] 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.
