Description

Turnover chute mouth for residual coal single bucket elevator

Technical Field

The invention relates to loading mechanical equipment in the technical field of coal coking chemical industry, in particular to a turnover chute for a residual coal single bucket elevator.

Background

In the coking production, a certain amount of residual coal is carried out in the coal leveling process of the coke pusher, the residual coal is collected in a residual coal hopper of the coke pusher in advance, and when the residual coal in the residual coal hopper is full, the residual coal on a coke pusher handle is put into a residual coal elevator hopper arranged on a coke oven platform, and is sent into a coal tower for recycling by a residual coal elevator. The current residual coal lifting device consists of a hopper, a feeder and a belt, wherein a feed opening is arranged below the hopper, and a spiral feeder and a lifting belt are connected with the hopper. When the coke pusher is used, the residual coal collected by the coke pusher is firstly poured into a lifting machine hopper, sent to a lifting belt by a screw feeder, and then sent to a coal tower by a residual coal lifting machine for recycling. The defect is that the coking coal has smaller fineness (particles smaller than 3mm account for 75%) and contains about 10% of water, so that the coking coal is easy to adhere to the wall of a hopper, is accumulated excessively thick for a long time, directly affects the discharging, causes the overflow of residual coal, pollutes the environment and wastes resources, and at the moment, the residual coal lifting device is required to be closed for manual shoveling, and the production continuity is destroyed; meanwhile, the residual coal slides downwards under the action of gravity, so that the residual coal in the lifting belt often overflows; the lifting belt needs to be replaced regularly, so that the coke pusher is affected to put residual coal, and the stability and the continuity of coke oven production are affected.

Therefore, development of a special residual coal single bucket elevator comprising a turnover chute, a single bucket trolley, a fixed rail, a lifting device and the like is needed to be developed.

2) When the fully loaded single-bucket trolley moves upwards and leaves the coal loading position, the hook on the single-bucket trolley is separated from the hook ring, and the external overturning chute nozzle overturns under the action of the gravity of the balance hammer, so that the external overturning chute nozzle and the internal chute nozzle are in a nearly vertical state, namely the device is automatically overturned to be in a closed state, at the moment, the coal in the lower coal bucket is sealed at the outlet of the internal chute nozzle, namely the coal in the lower coal bucket can not continuously fall.

Compared with the prior art, the invention has the beneficial effects that:

1) The device is matched with the single-bucket trolley, so that when the empty single-bucket trolley is ready for receiving coal, the overturning chute mouth is in an open state, and coal in the lower coal bucket enters the single-bucket trolley along the inner chute mouth;

2) The device is matched with the single-hopper trolley, so that when the fully loaded single-hopper trolley is ready to send coal to the upper coal hopper, the overturning chute is in a closed state, and the coal in the lower coal hopper is prevented from leaking;

3) The weight of the balance weight of the device can be adjusted, so that the overturning angle of the overturning spout can be adjusted, and the requirements of different overturning angles can be met;

4) The spring support arranged in the device can buffer the impact force of the hook on the overturning chute mouth in the descending process of the empty coal hopper trolley;

5) The device has the advantages of simple structure, convenient implementation and reliable use.
