Embodiment 1

[0027] refer to Figure 1-8 , a coal mill for thermal power generation, comprising a housing 1, a support leg 4 is fixedly connected around the lower end of the housing 1, a feeding pipe 2 is connected to the upper end of the housing 1, and a discharge port 29 is opened at the lower end of the housing 1, The inner walls on both sides of the upper end of the housing 1 are fixedly connected with connecting blocks 15, and the first rotating shafts 11 are rotatably connected to the two connecting blocks 15 through thrust ball bearings. Both first rotating shafts 11 are provided with reciprocating threads 20. Each reciprocating thread 20 is threaded through and connected with a connecting plate 10, and the middle position of the connecting plate 10 is rotatably connected with a second rotating shaft 24 through a thrust ball bearing. The support plate 8 fixedly connected with the housing 1 is provided with a plurality of leakage holes 16, and the ground and broken coal particles lea...

Embodiment 2

[0032] In Example 1, since the grinding seat 12 plays the role of squeezing and grinding, it is easy to make the coal block the leakage hole 16, so that the coal particles cannot be discharged in time, refer to Figure 6 , Figure 7 , Figure 8 , Figure 11 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, both ends of the lower surface of the connecting plate 10 are fixedly connected with connecting rods 9, and the connecting rods 9 penetrate through the support plate 8 and are fixedly connected with a mobile frame 18, which can be moved The frame 18 is fixedly connected with a plurality of conducting rods 19, the conducting rods 19 are located directly below the leakage hole 16, and the diameter of the conducting rods 19 is less than the inner diameter of the leakage hole 16, because the connecting rods 9 are fixedly connected with the connecting plate 10, When the connecting plate 10 moves upward, it will drive the connecting rod 9 ...

Embodiment 3

[0034] In embodiment 1, when coal is thrown in from the feed pipe 2, it will cause the coal to accumulate near the feed pipe 2, causing most of the coal to not be at the lower end of the grinding seat 12, which will affect the progress of coal grinding. Figure 1-6 , Figure 9-11 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, the housing 1 is fixedly connected with a bearing seat 32, the inner axial surface of the bearing seat 32 is fixedly connected with a reciprocating threaded rod 6, and the reciprocating threaded rod 6 is threaded A mobile plate 17 is connected through it, and a cross bar 31 is fixedly connected to the mobile plate 17. The cross bar 31 is located below the grinding seat 12. The cross bar 31 runs through the housing 1 and extends into the housing 1. The threaded rod 6 is fixedly connected with a second bevel gear 42, the housing 1 is rotatably connected with a third rotating shaft 33 through a bearing, and the thir...

Abstract

The invention relates to the technical field of coal mills for thermal power generation, in particular to a coal mill for thermal power generation. The coal mill comprises a housing; support legs arefixedly connected to the periphery of the lower end of the housing; a feed pipe communicates with the housing; a discharge port is formed in the lower end of the housing; connecting blocks are fixedlyconnected to the inner walls of the two sides of the upper end of the housing; first rotating shafts are rotatably connected to the two connecting blocks through thrust ball bearings; reciprocating threads are formed in the two first rotating shafts; a grinding base is fixedly connected to the lower end of a second rotating shaft; a support plate fixedly connected with the housing is arranged under the grinding base; a plurality of leakage holes are formed in the support plate; a gear is fixedly connected to the upper end of the second rotating shaft; a connecting plate is connected with a rack through a limiting mechanism; the rack is meshed with the gear; one end of the rack is hinged to a hinge rod; the hinge rod is hinged to the connecting blocks; and the upper ends of the two first rotating shafts are fixedly connected with first belt wheels. The coal mill has the characteristic that the coal briquette grinding and crushing effect is facilitated.

Description

technical field [0001] The invention relates to the technical field of coal mills for thermal power generation, in particular to a coal mill for thermal power generation. Background technique [0002] In thermal power generation, the chemical energy of the fuel is converted into steam heat energy by burning coal, then the steam heat energy is converted into mechanical energy, and finally the mechanical energy is converted into electrical energy. Simply put, it is to use fuel to generate heat and heat water to form high-temperature and high-pressure superheated steam. , and then the steam enters the steam turbine along the pipeline and continues to expand to do work, impacting the turbine rotor to rotate at high speed, driving the generator to rotate. [0003] When the coal is burning, in order to make the coal fully burnt, the coal pulverizer is used to grind the coal, and the coal is ground to increase the contact area with the air so as to ensure sufficient combustion. The...
