Description

Grate plate of grate cooler

Technical Field

The utility model belongs to the technical field of the cold machine spare part of comb, specifically be a cold quick-witted comb board of comb.

Background

With the development of building technology, cement also becomes an indispensable raw material in the building industry. The grate cooler is an important main machine device in a clinker firing system of a cement plant, has the main functions of cooling and conveying cement clinker, simultaneously provides hot air for a rotary kiln, a decomposing furnace and the like, and is a main device for heat recovery of the firing system.

At present, when a grate cooler runs, a movable grate plate is used for reciprocating motion so as to push clinker to move, and a cold air blower at the bottom of a grate bed generates cold air flow so as to cool the clinker at the top of the grate bed. In the using process of the existing grate plate, when the grate plate pushes clinker to move, a small part of clinker inevitably enters the interior of the grate plate, and at the moment, an operator needs to clean the clinker regularly.

Meanwhile, the cold air ventilation is not smooth due to the structural limitation of the grate plate of the existing grate cooler, and the cooling efficiency of cement clinker is not high; the grid plates are generally welded and fixed by adopting reinforcing ribs, so that the installation is inconvenient, and once the grid plates are damaged, the replacement time is long; if the grate plates are not welded and fixed, the problem of poor fixation can occur, and the grate plates are easy to shift in the using process, so that cement clinker is accumulated, the grate plates are burnt out, and the damage rate is greatly increased.

SUMMERY OF THE UTILITY MODEL

To the deficiency of the prior art, the utility model aims to provide a cold quick-witted comb board of combing to solve the problem that provides among the above-mentioned background art.

In order to achieve the above object, the present invention provides the following technical solutions:

the grate plate of the grate cooler comprises a grate plate seat, a vent and a fixed connecting end arranged at the rear end of the grate plate seat, wherein the vent is arranged on the grate plate seat, stepped convex structures and stepped notch structures are respectively arranged on two sides of the grate plate seat, grate bars, wave-shaped baffles and a bottom base plate are sequentially arranged in the vent from top to bottom, the grate bars are arranged at the upper end of the vent, the wave-shaped baffles are fixed on the inner wall of the vent all around, the bottom base plate is fixed at the lowest end of the vent, vent holes are formed in the convex peaks of the wave-shaped baffles and the grate bars and the bottom base plate, and a dust outlet is formed in the front end face of the grate plate seat at the tail end of a valley of the wave.

Preferably, the grate bars are provided with a plurality of grate bars.

Preferably, a raised limiting plate is arranged on the upper end face of the grate plate seat at the rear side of the vent, a limiting groove is arranged on the lower end face of the grate plate seat at the front side of the vent, and the limiting plate and the limiting groove are the same in shape.

Preferably, a threaded hole is formed in the fixed connecting end, and a fixing bolt is installed in the threaded hole.

Preferably, the dust outlets are provided with a plurality of dust outlets which are arranged in parallel at equal intervals.

Preferably, the stepped convex structure and the stepped concave structure are male-female complementary structures.

Preferably, the wavy baffle is arranged in an inclined shape with a low front part and a high back part.

The beneficial effects of the utility model reside in that:

the grate plate of the grate cooler of the utility model realizes the mutual fixation among a plurality of grate plates through the mutual lapping of the stepped convex structures and the stepped concave structures among the grate plates and the mutual clamping of the convex limiting plates and the limiting grooves, and simultaneously realizes the fixation of the whole grate plate through the fixed connecting ends, the installation is firm, and the deflection of the grate plate can be prevented; through set up the wave baffle in the vent, utilize the valley of wave baffle, collect the cement clinker that leaks into in the vent to through the dust export on the comb plate seat front end face, carry out the ejection of compact under the comb plate reciprocating motion effort, need not operating personnel and clear up convenient and reliable in to the comb plate. The utility model discloses cold quick-witted comb board of comb, simple structure is simply suitable for, and ventilation effect is good, and cooling efficiency is high, simple to operate, and is not fragile, safe and reliable.
