Ring-shaped chute material distributor of cylindrical silo

Abstract

The invention discloses a ring-shaped chute material distributor of a cylindrical silo. The ring-shaped chute material distributor comprises a middle straight-section fixed chute, lower end of which is fixed on the ground, wherein a middle straight-section movable chute is connected at the upper end of the middle straight-section fixed chute through a swing mechanism; a charge section chute is connected at the upper end of the middle straight-section movable chute; a rotary material-receiving forked-section chute is arranged on the side surface of the charge section chute; the charge section chute and the rotary material-receiving forked-section chute form an inverted-Y-shaped structure; an inclined-section chute comprises an electro-hydraulic bulkhead gate, a middle inclined-section chute and an unloading turn-section chute which are sequentially connected with the lower end of the rotary material-receiving forked-section chute; a bent-angle outlet which is perpendicular to the ground is formed in the lower end of the unloading turn-section chute; a ring-shaped rail is arranged, along a ring-shaped coal unloading ditch, at the lower end of the a bent-angle outlet of the unloading turn-section chute; and a travelling mechanism is arranged on the ring-shaped rail. The equipment swing mechanism adopts a hollow type swing mechanism, so that materials can be unloaded into the cylindrical silo through a central position, thereby further improving volume fraction of the cylindrical silo. The ring-shaped chute material distributor is simple in structure, good in working stability, low in fault rate and long in maintenance period.

Description

technical field [0001] The invention relates to a distributing device for a bulk material silo, in particular to a circular chute distributing machine for a cylindrical silo. Background technique [0002] At present, in the circular silos (diameter range: 12m ~ 36m) of enterprises such as coal mines, coal preparation plants, and grain storage, most of the top material distribution equipment uses scraper machines, belt conveyors and other equipment to unload at one or more points. The result of this is that the utilization rate of the warehouse capacity is not high, and the effective storage is guaranteed under the condition of sacrificing the height of the warehouse, which leads to an increase in civil engineering investment, a high lifting height of materials, and an increase in operating costs. For this reason, in power systems such as thermal power plants, often adopt large-scale rotary distributing machine equipment to carry out annular distributing, such as the rotary d...

Problems solved by technology

[0002] At present, in the circular silos (diameter range: 12m ~ 36m) of enterprises such as coal mines, coal preparation plants, and grain storage, most of the top material distribution equipment uses scraper machines, belt conveyors and other equipment to unload at one or more points. The result of this is that the utilization rate of the warehouse capacity is not high, and the effective storage is guaranteed under the condition of sacrificing the height of the warehouse, which leads to an increase in civil engineering investment, a high lifting height of materials, and an increase in operating costs.

For this reason, in power systems such as thermal power plants, often adopt large-scale rotary distributing machine equipment to carry out annular distributing, such as the rotary distributing machine disclosed by the Chinese invention patent that the authorized announcement number is CN1907825B, and this equipment is often due to existing in use. Occupies a large area, complex equipment structure, many reloading links, high investment costs, resulting in high equipment failure rate and reduced service life
