Embodiment Construction

[0049] The structure of the silo buried rotary spiral anti-hardening, freezing and jamming process is as follows: figure 1 As shown, it includes a central rotary discharge cylinder 8 arranged at the center of the silo bottom plate 2 . The lower part of the central rotary discharge barrel 8 is connected to the silo bottom plate 2 through the slewing support 5, and the upper part is connected to the circular protective cap 7 through the slewing support 5, so that it can freely move between the silo bottom plate 2 and the circular protective cap 7. rotate. The static accumulation angle of the material formed by the circular protective cap 7 is sufficient to prevent the material from entering the upper and lower slewing bearings.

[0050] At the outer end of the silo bottom plate 2, an annular rotary track 16, 17 with the silo center as the center of the circle is installed, such as figure 2 , 4 shown. The rails 16,17 are covered by an umbrella-shaped protective eaves 3 that ...

Abstract

The invention relates to an anti-hardening, anti-freeze and anti-locking method for a silo buried revolving spiral, comprising the following steps: mounting a spiral longitudinal whole-course subresonance loosening and activating unit at a bearing pedestal of the silo buried revolving spiral, connecting relevant devices flexibly, mounting a circulating spray system at non-working face of spiral vanes around a spiral shaft, introducing water, thinners, hot steam and inert gases, restricting revolution direction of buried revolving spiral and adopting special switch technology. By using the anti-hardening, anti-freeze and anti-locking method for the silo buried revolving spiral and supporting devices, the buried revolving spiral is free of unfavorable influence caused by level height, material characteristics and environmental temperature, and system operation reliability can be improved due to normal work of an anti-hardening, anti-freeze and anti-locking support device. The method is suitable for mounting in flat-bottom bulk material silos with large diameter, especially for unloading of high-viscosity big-chunk high-moisture complicated-characteristic material in severe cold districts.

Description

technical field [0001] The invention relates to a large flat-bottomed silo with a buried rotary screw, in particular to a method for preventing hardening, freezing and jamming of the buried rotary screw. The invention also relates to an anti-hardening, freezing, and jamming anti-hardening, freezing, and jamming device used in conjunction with the silo buried rotary screw anti-hardening, freezing, and jamming method. Background technique [0002] The silos currently used to store bulk materials basically have the following structures: [0003] One is a first-in-first-out type silo with a material suspension type cone bottom represented by CN 1061310C and CN 2520311Y, which is composed of a silo roof, a silo body and a silo bottom cone. The outer ring of the bottom of the mushroom-shaped annular cone with the center column concentrically connected to the ring platform, the gap between the inner ring and the ring platform under the center column forms an inner ring slot-shaped...
