Problems solved by technology

[0002] At present, before the viscous oil shale enters the retort furnace for processing, it needs to be crushed to reduce the particle size of the furnace, which is beneficial to increase the heating rate and oil recovery rate; the water content in the viscous oil shale is 5-20%, which has high water content, Due to the high viscosity, the viscous oil shale will stick to the surface of the rollers and teeth during crushing, and the more sticky, the thicker it will eventually fill the surface of the rollers and teeth, and the gap between the teeth, so that large particles cannot enter the crusher. Even being extruded by viscous oil shale, the feed particle size is greatly restricted. When the viscous oil shale sticks too much, the crusher cannot operate; in view of the above reasons, an anti-adhesion crushing method for viscous oil shale crushing is now proposed.

Embodiment 1

[0017] The upper middle part of the casing 1 is provided with the feeding port 2, the lower part of the casing 1 is provided with the feeding port 11, the left roller 5 is arranged on the left side of the casing 1, and the left crushing teeth are evenly arranged on the outside of the wall of the left roller 5. 7. The right roller 6 is arranged on the right side of the casing 1, and the right crushing teeth 8 are evenly arranged on the outside of the wall of the right roller 6, and the left crushing teeth 7 and the right crushing teeth 8 are correspondingly set; the left roller 5 and the The seams of the right roller 6 are respectively set on the same line as the centers of the feeding port 2 and the feeding port 11;

[0018] The left spreader 3 is set on the left side of the feed port 2 in the casing 1, and the spray port of the left spreader 3 corresponds to the left side of the left roller 5, and the right spreader is set on the right side of the feed port 2 in the casing 1 ...

Embodiment 2

[0022] After the left crushing tooth 7 and the right crushing tooth 8 with the attachment layer rotate and engage, the viscous oil shale is continuously conveyed to the feed port 2 through the conveying device. Crushing is carried out in the occlusal crushing teeth of the crushing teeth 7 and the right crushing teeth 8, and the crushed viscous oil shale and tailings dry powder adhesion layer are separated from the natural fall and discharged through the discharge port 11.

Embodiment 3

[0024] The viscous oil shale falls naturally, while the left crushing tooth 7 and the right crushing tooth 8 rotate, the scraper heads of the left scraper 9 and the right scraper 10 respectively face the gap between the left crushing tooth 7 and the right crushing tooth 8 and the left roller 5, The cylinder wall surface of the right roller 6 is cleaned, and the viscous oil shale that falls after cleaning falls into the discharge port 11, and the pulverized viscous oil shale discharged from the discharge port 11 is transported to the dry distillation furnace for processing.

Abstract

The invention discloses a use method for an anti-adhesion crusher for crushing adhesive oil shale. When the crusher crushes the adhesive oil shale, tailings dry powder conveyed by a scattering and feeding device through high pressure pipelines is continuously sprayed by spraying holes of a left scattering device and a right scattering device which respectively correspond to a left roller and left crushing teeth and a right roller and right crushing teeth to form adhesion layers; the crushed adhesive oil shale and the tailings dry powder adhesion layers naturally fall down and are discharged by a discharging hole; and meanwhile, scraper heads of a left scraper and a right scraper respectively clean occluded gaps of the left crushing teeth and the right crushing teeth and the roller walls of the left roller and the right roller. The oil shale tailings powder is uniformly sprayed on the surfaces of the rollers and teeth, a layer of tailings dry powder anti-adhesion layer is formed, the scrapers are correspondingly arranged between tooth pitches of the two rows of crushing teeth, the production efficiency of the crusher for the adhesive oil shale is improved, and a crushing quality of the adhesive oil shale is ensured.

Description

technical field [0001] The invention relates to equipment for crushing and processing viscous oil shale, in particular to a method for using an anti-adhesion crusher for crushing and processing viscous oil shale.
