Embodiment Construction

[0039] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] like Figure 1-3 As shown, an embodiment of the vibrating screen according to the present invention includes a beam installed on a shock-absorbing base, a first side plate 12 and a second side plate 13 installed at both ends of the beam, a sieve plate 1 placed on the top of the beam, and a motor , the first side plate 12 and the second side plate 13 are parallel to each other. There are multiple beams connected between the first panel 12 and the second side panel 13, including a first beam 21, a second beam 22, a third beam 23, a fourth beam 24, a fifth beam 25, and a sixth beam 26. , the seventh beam 27 . The cross beams are installed between the first side plate 12 and the second side plate 13 parallel to each other. A sieve plate 1 is arranged on the upper part of the plurality of beams. The first crossbeam 21, the second cros...

Abstract

The invention relates to a vibrating screen. The vibrating screen comprises crossbeams, a first side plate (12), a second side plate (13), a screen plate (1) and a motor, wherein the crossbeams are mounted on a damping base, the first side plate (12) and the second side plate (13) are mounted at two ends of the crossbeams, the screen plate (1) is arranged on the upper portions of the crossbeams, a screen surface accounting for one third of the screen surface area of the screen plate (1) is a grid section type screen surface with the classification grain size pore diameter being 80%, and a screen surface accounting for two thirds of the screen surface area of the screen plate (1) is a screen surface with regular hexagon screen pores. The vibrating screen is small in floor area, the pore opening ratio of the screen plate is high and is more than twice of that of a screen plate with similar strength, and processing capacity of the screen plate is more than 1.5 times of that of a screen plate with the same process dimension screen surface area; the vibrating screen is high in classification efficiency since materials on coal flow lines of the screen plate are the same in screen penetration probability.

Description

technical field [0001] The invention relates to the technical field of coal preparation machinery and equipment, in particular to a linear coal vibrating screen. Background technique [0002] Coal preparation is mainly based on the difference in physical and chemical properties between coal and gangue. In the coal preparation plant, the impurities in the raw coal are removed mechanically and divided into products of different quality and specifications to meet the needs of different users. Require. Coal preparation methods are mainly divided into wet coal preparation and dry coal preparation. Wet coal preparation mainly adopts water separation. Because wet coal preparation encounters serious muddying when the coal has high moisture content, and there is a problem of freezing in alpine regions, The dry coal preparation can avoid the above contradictions. [0003] The Chinese invention patent application with the application number 201310447520.2 discloses an inertial coal v...
