Problems solved by technology

[0004] However, the screened large lumps of coal still need to be transported by operators, so that the coal lumps can be re-introduced into the coal crusher for crushing, so that the coal lumps can be fully utilized, but each time the large coal lumps are transported, operators are required On the whole, it is inconvenient and troublesome, and needs to be improved

Abstract

The invention discloses a crushed coal screening system, which relates to the technical field of thermoelectricity. The key points of the technical solution are: a crushing device, a screening device and a coal lump transportation device; Inlet and outlet, the outlet includes the first outlet and the second outlet; the crushing device is erected above the screening device, the crushing device includes a feeding port and a discharge port, and the discharge port is aligned with the inlet of the screening device The material opening is set; the coal block transportation device includes a mounting seat and a conveyor belt installed on the mounting seat, and the conveyor belt is set upward at an inclination; a discharge plate is provided at the first exit, and the discharge plate extends downward at an incline; the upper end of the mounting seat is close to the crushing device There is a gap at the feeding port, and a material guide plate is also arranged on the mounting seat. Large coal blocks can be directly transported to the crusher through the coal block transport device, which makes the overall operation more convenient, and at the same time, the crushing of the crushing device also makes the use of coal more fully.

Description

technical field [0001] The invention relates to the technical field of thermoelectricity, more specifically, it relates to a crushed coal screening system. Background technique [0002] Thermal power plants usually burn coal to generate electricity, but before the coal is introduced into the boiler, it needs to be crushed and ground into powder by a coal mill to ensure that the coal is completely burned. However, the coal used in thermal power plants is generally ungraded raw coal with a particle size between 0 and 300 mm, most of which do not meet the requirements of coal mills. Before the coal is sent to the coal mill, it must go through a series of screening and crushing work, so that the coal that does not meet the requirements of the coal mill is screened out, so that the coal mill can operate normally. [0003] The existing Chinese invention patent with the application publication number of CN107983638A discloses a screening device for crushing fired coal in a boiler,...
