Abstract

The invention discloses an improved high-temperature spiral ash cooler. Under the condition of ensuring thermal expansion elongation of a spiral bearing, the ash cooler can work normally. The ash cooler comprises a spiral shaft, bearing blocks at two ends, a shell and a base. The ash cooler is characterized in that in the bearing blocks at the two ends, the bearing block at one end is fixed, and the bearing block at the other end is arranged in a track which can slide along the axial direction.

Description

A kind of improved high-temperature spiral ash cooler

(1) technical field

The present invention relates to the spiral ash cooler manufacturing field of equipment, be specially a kind of improved high-temperature spiral ash cooler.

(2) background technology

Existing high-temperature spiral ash cooler, its structure comprises helical axis, fixing bearing block, the housing in two ends, it is generally as the furnace bottom ash handling equipment of 650 ℃ of temperature and above temperature, when high temperature, helical axis thermal expansion elongation because the two end axles bearing is fixed, can produce the distortion of following two aspects: 1) helical axis flexural deformation, rub mutually with the high-temperature spiral ash cooler housing, bad housing rubs; 2) with the inclined to one side or displacement in bearing block top at axle two ends, damage bearing, thereby cause high-temperature spiral ash cooler normally not move.

(3) summary of the invention

At the problems referred to above, the invention provides a kind of improved high-temperature spiral ash cooler, it guarantees that it can normally move under the screw bearing thermal expansion elongation situation.

Its technical scheme is such: it comprises helical axis, two end axles bearing, housing, base, it is characterized in that: described two end axles bearing, and wherein the bearing block of an end is fixed, and the bearing block of the other end is loaded in the track that can slide vertically.

It is further characterized in that: the bottom of the bearing block of the described other end is installed on axial trajectory, and described axial trajectory is installed on described base, and the bearing block top of the described other end is installed in the axial trajectory of top board;

Its interior bearing of described two end axles bearing all adopts high-temperature bearing; The axial trajectory of described base, the axial trajectory of described top board all have lubricating oil.

In the said structure of the present invention, because the described two end axles bearing wherein bearing block of an end is fixed, the bearing block of the other end is loaded on vertically in the sliding rail, when high temperature, and screw bearing thermal expansion elongation, the bearing block that helical axis after the elongation drives the other end slides along axial trajectory, helical axis after the described elongation not can with casing friction, and then the bad housing that rubs also can be with the bearing block top at helical axis two ends partially or displacement, and then the damage bearing, so it can normally move; And the setting of high-temperature bearing and axial trajectory all have lubricating oil further to guarantee the normal operation under the hot environment.

(4) description of drawings

Fig. 1 is a front view structural representation of the present invention.

(5) specific embodiment

See Fig. 1, the present invention includes helical axis 1, two end axles bearing, housing 2, base 3, the two end axles bearing wherein bearing block 4 of an end is fixed, the bottom of the bearing block 5 of the other end is installed on axial trajectory 6, axial trajectory 6 is installed on base 3, bearing block 5 tops of the other end are installed in the axial trajectory 7 of top board 8, and the bearing in the bearing block 4 of an end, the bearing block of the other end 5 all adopts high-temperature bearing; The axial trajectory 6 of base 3, the axial trajectory 7 of top board 8 all have lubricating oil (belong to existing mature technology, do not draw among the figure).
