Description

Vehicle-mounted coke powder laying device suitable for heat recovery coke oven coal charging coke pusher

Technical Field

The utility model relates to the technical field of coke oven coal charging smoke abatement, in particular to a vehicle-mounted coke powder spreading device suitable for a heat recovery coke oven coal charging coke pusher.

Background

The coke oven is the main equipment in coking production and mainly comprises a coking chamber, a combustion chamber, a regenerator, a chute area, a base part, a flue and the like. A coking chamber, also called a burner, is generally composed of tens of burners, each of which is provided with a respective burner door which covers the burner opening. In the coke discharging and coal charging processes, each furnace door of the coke oven needs to be opened and closed periodically, and the coke oven is matched with a coal charging coke pusher to complete the operations of opening the door, pushing coke and conveying coal cakes. At present, because the coal cake of the heat recovery coke oven is flat, the upper surface area of the coal cake is large, the coal cake is fully contacted with air when entering the coke oven, so that coal powder is combusted, a large amount of smoke is emitted, smoke pollution is caused, and the coking effect is influenced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a on-vehicle coke powder device of spreading suitable for heat recovery coke oven coal charging coke pusher, its flue gas volume that effectively reduces the coal charging in-process.

In order to solve the technical problem, the utility model provides a technical scheme does: the vehicle-mounted coke powder spreading device comprises a coke pusher, wherein the coke pusher is provided with a coal charging device for controlling coal cakes to move, a coke head spreading storage bin is arranged above the coal charging device and is arranged on one side close to a coke oven, the coke pusher is provided with a coke powder bin, the coke powder bin is communicated with the coke head spreading storage bin through a conveying pipeline, one side of the coke head spreading storage bin, facing the coal charging device, is provided with a screening net for uniform coke powder, a vibrator is arranged on the screening net, the outer side of the screening net is provided with a drawable gate plate, and the gate plate is controlled to open and close the coke head spreading storage bin for spreading the powder.

As an improvement, a feeding device is arranged on the conveying pipeline, and the feeding device is a fan or a mechanical conveyor.

As an improvement, the coke powder capacity in the coke paving head storage bin is the amount of once coke powder paving.

As an improvement, the gate plate is controlled in a linkage manner with the vibrator.

Compared with the prior art, the utility model the advantage lie in: before the coal cake enters the coke oven, a layer of fine coke powder is arranged on the upper layer of the coal cake, a coke paving head storage bin is arranged at the front end of the coal charging device, in the moving process of the coal cake, the coke powder is scattered by a vibrator, a completely covered coke powder layer is formed on the upper layer of the coal cake, the coke powder layer separates the coal powder layer, smoke is prevented from being contacted with air, and therefore the smoke amount in the coal charging process is reduced.
