Abstract
The present invention relates to a pneumatic air booster, and provides a pneumatic air booster, which: can minimize the amount of air supplied to a pipeline, through which objects move, of high-density transfer equipment for transferring heavy objects with high specific gravity such as sand and limestone in a blower, a compressor or the like; enables smooth transfer of the objects in the pipeline and reduces even the impact to the pipeline so as to be advantageous in maintenance and repair of equipment; and is independently operated when the air booster is applied to a pneumatic conveying system, so as to enable pressure adjustment of the pipeline, so that a monitoring and control system is simplified, and thus costs for constructing the system can be reduced.
Claims3
A pneumatic air booster (100) which comprises;
- a first body (110) and a second body (111) coupled to the first body (110),
- wherein an air inlet (112) and an air outlet (113) are formed on a side of the body (111),
- wherein a pressure chamber (114) and an air control passage (115) are formed in a lower part of the second body (111),
- a bonnet (190) that is coupled to an upper part of the first body (110) and forms a pressure control chamber (116),
- a lower cover (120) that closes the pressure chamber (114) of the first body (110),
- a valve (140) that is installed inside the pressure chamber (114) and opens and closes the air control passage (115),
- a valve spring (150) that is installed in the pressure chamber (114) and presses the valve (140) upward,
- a shaft (160) that passes through the pressure chamber (114) and the pressure control chamber (116), wherein a lower end of the shaft (160) is coupled to the valve (140) and lifts and lowers the valve (140) to open and close the air control passage (115),
- a valve seat (170) provided in the pressure control chamber (116) in a manner of being lifted and lowered and supported on and upper end of the shaft (160),
- wherein a connection passage (102a) is extended between the air outlet (113) of the first body (110) and the pressure control chamber (116) of the bonnet (190), wherein the air outlet (113) of the first body (110) and the pressure control chamber (116) of the bonnet (190) communicate with each other through the connection passage (102a),
- wherein, when air of the air outlet (113) flows into the pressure control chamber (116) through the connection passage (102a), a pressure in the pressure control chamber (116) increases, and the valve seat (170) is pushed downward.
