Dust-free screening and crushing integrated equipment

Abstract

The invention discloses dust-free screening and crushing integrated equipment. The integrated equipment comprises a machine frame, a first level crushing device, a second level crushing device, a third level crushing device, a screening device and a dust removing device. The top of the machine frame is provided with a feeding inlet and a suction opening. The first level crushing device, the second level crushing device, the third level crushing device and the screening device are located in the machine frame and are arranged in a dust-free screening and crushing integrated equipment body in a totally closed mode. The dust removing device is located outside the machine frame and connected with the suction opening. The dust-free screening and crushing integrated equipment has the beneficial effects that outdoor arrangement is adopted, concrete pouring and embedded part fixing and bearing are adopted for infrastructure construction, and a separate crushing building does not need to be constructed; dust leakage is avoided, an original coal crushing room pervaded with dust is removed, the working environment is optimized, and the cleaning workload is also reduced; the occupied area is decreased, the space is reduced, and the cost is reduced substantially.

Description

technical field [0001] The invention relates to the technical field of screening machines, in particular to a dust-free screening and crushing integrated machine equipment. Background technique [0002] At present, the coal conveying systems of thermal power plants and coal chemical industries need to crush the materials in advance in order to make the materials fully combustible in the boiler. At present, domestic and foreign crushers have the following shortcomings when crushing materials: [0003] 1. It is necessary to build a separate crushing building. The crushing building is divided into three floors. The top layer is equipped with a coarse crusher, the middle layer is equipped with a drum screening machine, and the bottom layer is a fine crusher. This leads to serious dust pollution, high noise and large vibration in the crushing building. , poor working environment; [0004] 2. The layout of the three-story crushing building requires a large amount of civil constr...

[0003] 1. It is necessary to build a separate crushing building. The crushing building is divided into three floors. The top layer is equipped with a coarse crusher, the middle layer is equipped with a drum screening machine, and the bottom layer is a fine crusher. This leads to serious dust pollution, high noise and large vibration in the crushing building. , poor working environment;

[0004] 2. The layout of the three-story crushing building requires a large amount of civil construction, high cost, high crushing cost, and high labor maintenance cost
