Abstract
The utility model discloses a pebble coal cushioning, collecting and feeding device, which can solve the problems that the existing device is non-uniform in feeding and less prone to conveying larger blocks of pebble coal. The pebble coal cushioning, collecting and feeding device is characterized in that a feed port is arranged at the upper part of a housing, an air inlet pipe and a discharge pipe are arranged at the lower part of the housing, and the feed end of the discharge pipe is of the shape of an oblique mouth; and the tail end of the air inlet pipe is in contact with the top end of the discharge pipe, and the uppermost end of the air inlet pipe and the uppermost end of the discharge pipe are arranged on the same plane. According to the pebble coal cushioning, collecting and feeding device disclosed by the utility model, the discharge pipe with the feed end which takes the shape of the oblique mouth can easily conveyor the larger blocks of the pebble coal; and the pebble coal cushioning, collecting and feeding device is further provided with a cushioning device which can enable the pebble coal to separately fall to the two sides, a loosening pipe can help the pebble coal enter into the discharge pipe, and the pebble coal cushioning, collecting and feeding device has the advantages of simple structure and convenience in manufacturing.
Description
Technical field:
The utility model relates to the mass transport parts in a kind of thermal powerplant stone coal gas power delivery system, relates to a kind of stone coal collecting charging gear or rather.
Background technology:
The stone coal is the stone that thermal power plant's medium-speed pulverizer produces in pulverizing process, is mainly derived from big, the difficult spoil that grinds of density in the raw coal.The main manual emission of common discharging modes, waterpower discharging, dry type discharging etc.Part thermal power plant has adopted pneumatic conveying method to the stone coal in recent years, and transport efficiency is high, improved working environment, alleviated hand labor intensity.But the feed arrangement feed that air-transport system uses is inhomogeneous, blocks discharge nozzle easily, and is difficult for taking away than the stone coal of bulk.
Summary of the invention:
The purpose of the utility model is that the deficiency that overcomes prior art provides a kind of stone coal buffering simple in structure, reliable, that improve workman's labor condition to collect charging gear.
The utility model comprises housing, it is characterized in that on housing top inlet point being set, and the bottom is provided with air inlet pipe and discharge nozzle, and the feed end of discharge nozzle is the angle shape; The top of the end of air inlet pipe contact discharge nozzle, the top of air inlet pipe and the top of discharge nozzle are at grade; Described discharge nozzle diameter is less than air inlet pipe.
The top of described air inlet pipe, discharge nozzle is provided with the shock absorber that the stone coal falls, and separates the stone coal of whereabouts to both sides, avoids the stone coal to smash air inlet pipe, discharge nozzle.Described shock absorber is a pipe, or the shape that is in the shape of the letter V.
Described air inlet pipe is told a loose tube, and the exit end of loose tube is arranged on the below of discharge nozzle, so that blow pine to the stone coal, auxiliary stone coal gets into discharge nozzle.
Outside housing, inlet point, feed pipe, discharge nozzle are provided with operated pneumatic valve.
On the described housing inspection socket is set, is convenient to check stone coal conveying situation.
Can be known by technique scheme, the utlity model has following beneficial effect: 1, described housing can be made the square of easy processing; 2, the feed end that is provided with is the discharge nozzle of angle shape, carries the stone coal than bulk easily; 3, the shock absorber that is provided with can separate the stone coal of whereabouts to both sides, and the loose tube of setting can assist the stone coal to get into discharge nozzle.4, simple in structure, easy to make.
Description of drawings:
Fig. 1 is the front view of the utility model.
Fig. 2 is the utility model birds-eye view.
Among the figure, 1, housing, 2,4,8, operated pneumatic valve, 3, air inlet pipe, 5, inlet point, 6, inspection socket, 7, shock absorber, 9, discharge nozzle, 10. loose tube.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises housing 1, inlet point 5, air inlet pipe 3, discharge nozzle 9 etc.Described inlet point 5 is on the top of housing 1, and described air inlet pipe 3 is arranged on the lower left side of housing 1, and described discharge nozzle 9 is the negative pressure transportation pipeline, is arranged on the right side, bottom at housing 1.In conjunction with shown in Figure 2, the feed end of discharge nozzle 9 is the angle shape.The top of the end of air inlet pipe 3 contact discharge nozzle 9, the top of the top of air inlet pipe 3 and discharge nozzle 9 at grade.The diameter of described discharge nozzle 9 is less than air inlet pipe 3.Described air inlet pipe 3 is told a loose tube 10, and its exit end is arranged on the below of discharge nozzle 9.
Dotted line among Fig. 1 is depicted as the stone coal, and arrow is represented air-flow.
The top of described air inlet pipe 3, discharge nozzle 9 is provided with the shock absorber 7 that the stone coal falls, and separates the stone coal to both sides.Described shock absorber 7 is a pipe, or the shape that is in the shape of the letter V.
Outside housing 1, inlet point 5 is provided with that operated pneumatic valve 4, feed pipe 3 are provided with operated pneumatic valve 2, discharge nozzle 9 is provided with operated pneumatic valve 8.
On the described housing 1 inspection socket 6 is set.
