Abstract
The utility model provides a chute seam coal powder injection prevention device, is applicable to prevention smalls loading in -process buggy in the coal powder injection of chute seam crossing. The prevention device includes chute and surge hopper, the surge hopper bottom is arranged in to the chute, evenly distributed has four compressed air passageways on the surge hopper lateral wall. The device simple structure, job stabilization, the effect is obvious, the effectual emergence that has prevented buggy follow chute seam crossing coal powder injection phenomenon.
Description
Technical field
The utility model relates to a kind of chute seam coal powder injection preventing mean, to be particularly applicable in prevention smalls entrucking process coal dust in the coal powder injection of chute seam.
Background technology
During the smalls entrucking commonly used at present, because whole chute is in full closeding state and the instant flow rate of coal is very large, a large amount of air the gap of chute and bottom, quantitative storehouse docking port by compressing rear brute force attack, a large amount of coal dusts is caused to be ejected together in company with pressurized air, environment around gross pollution entrucking tower, and larger coal dust blocks the sight line of entrucking personnel, during entrucking, easily there is unbalance loading phenomenon; , to be ejected and coal in chute is placed in railway carriage due to pressurized air, chute interior also can form a very powerful negative pressure, and this negative pressure has had a strong impact on the lifting of chute in entrucking process, very easily causes entrucking accident meanwhile.
Summary of the invention
For the shortcoming in above-mentioned, it is simple that the utility model provides a kind of structure, working stability, successful, and the device that effectively can prevent the coal powder injection of chute seam.
For achieving the above object, a kind of chute seam of the utility model coal powder injection preventing mean comprises chute and surge hopper, and described chute is placed in bottom surge hopper; Described surge hopper sidewall is evenly distributed with four compressed air channels.
Beneficial effect: in the utility model, in quantitative storehouse, a surge hopper is added to the top of opening a sluice gate edition bottom and chute, surge hopper surrounding is evenly distributed with four compressed air channels, actv. ensure that chute interior and outside equilibrium of pressure, prevents the generation of chute seam coal powder injection phenomenon.
Accompanying drawing explanation
Fig. 1 is a kind of chute seam of the utility model coal powder injection preventing mean structural representation;
In figure: 1-chute, 2-surge hopper, 3-compressed air channel, 4-chute seam, 5-flashboard, 6-quantitatively storehouse, 7-smalls.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described:
Consult Fig. 1, a kind of chute seam coal powder injection preventing mean, comprise chute 1 and surge hopper 2, described chute 1 is placed in bottom surge hopper 2; Described surge hopper 2 sidewall is evenly distributed with four compressed air channels 3.
Working process:
In entrucking process, the flashboard 5 in quantitative storehouse 6 is opened, and instantaneous large discharge smalls 7 enters chute 1 by surge hopper 2, discharges chute 1 after a large amount of air is compressed by compressed air channel 3, avoids the generation of chute seam 4 coal powder injection phenomenon; When discharging is complete, chute interior forms zone of negative pressure, and a large amount of air can enter chute 1 by compressed air channel 3 and fill up negative pressure, prevents chute 1 from being unloaded smalls and holds, avoid the generation of entrucking accident.
Claims (1)
1. a chute seam coal powder injection preventing mean, comprises chute (1) and surge hopper (2), and described chute (1) is placed in surge hopper (2) bottom; Described surge hopper (2) sidewall is evenly distributed with four compressed air channels (3).
