Embodiment 1

[0038] Such as Figure 1-Figure 6 As shown, an impurity removal and screening device for clean coal processing includes a main frame body 1, on which a primary screening mechanism and a secondary screening mechanism are sequentially arranged, and the primary screening mechanism includes a main frame body 1, the filter inclined net box 2 at the top, and the opposite side of the filter inclined net box 2 and the main frame body 1 is provided with a vibration guide assembly-5, the mesh of the filtered inclined net box 2 is compatible with the clean coal block, and the secondary The screening mechanism includes a screening net box 8, and the opposite side of the screening net box 8 and the main frame body 1 is provided with a vibration guide assembly 2 7, the sieve hole of the screening net box 8 is smaller than the clean coal block, and the main frame body 1 One side is provided with a lump coal processing mechanism, and the opposite side of the lump coal processing mechanism and...

Embodiment 2

[0048] Based on the impurity removal and screening device for clean coal processing provided in the first embodiment of the application, the second embodiment of the application proposes another impurity removal and screening device for clean coal processing. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0049] The second embodiment of the present invention will be further described below in conjunction with the drawings and implementation methods.

[0050] Such as Figure 7-Figure 9 As shown, in the second embodiment, the top outer wall of the vibrating blanking plate 9 is fixedly connected with a plurality of material guide plates 901, and both ends of the first elliptical plate 19 and the second elliptical plate 20 are provided with installation cavities. Both are rotatably connected with a pulley 32; by means of the above-me...

Abstract

The invention relates to the technical field of clean coal processing, in particular to an impurity removing and screening device for clean coal processing, which comprises a main frame body, a primary screening mechanism and a secondary screening mechanism are sequentially arranged on the main frame body, and the primary screening mechanism comprises a filtering inclined net cage arranged at the top end of the main frame body; the secondary screening mechanism comprises a filtering inclined net cage, a first vibration guide assembly is arranged on the side, opposite to the main frame body, of the filtering inclined net cage, meshes of the filtering inclined net cage are matched with clean coal briquettes, the secondary screening mechanism comprises a screening net cage, and a second vibration guide assembly is arranged on the side, opposite to the main frame body, of the screening net cage. According to the screening device, the arranged second oval disc can rotate along with the shaft rod, so that the screening net cage is pressed at fixed frequency, and the purpose of improving the screening effect of the screening net cage is achieved; and the arranged first elliptic disc can abut against the arranged side block at a fixed frequency along with rotation of the shaft rod so as to be matched with the arranged connecting spring to drive the vibration discharging plate to vibrate, and therefore screened small impurities are shaken off.

Description

technical field [0001] The invention relates to the technical field of clean coal processing, in particular to an impurity removal and screening device for clean coal processing. Background technique [0002] Clean coal technology refers to new technologies such as processing, transformation, combustion and pollution control in the whole process from mining to utilization of coal, mainly to reduce pollutant emissions and improve utilization efficiency, including clean production technology, clean processing technology, high-efficiency Clean conversion technology, high-efficiency clean combustion and power generation technology, and coal-fired pollution emission control technology, etc. my country has carried out a lot of research, development and promotion around improving the efficiency of coal development and utilization and reducing environmental pollution. Coal processing refers to the processing of raw coal by physical methods before it is put into use. This is the pre...
