Abstract
The utility model relates to a moulded coal pipeline transportation type double-way pressurizing device capable of carrying out double-way pressurization on moulded coal in a pipeline through a feeding wheel and a centrifugal pump. The moulded coal pipeline transportation type double-way pressurizing device comprises a forward inlet pipe, an exhaust valve, the feeding wheel, a buffer tank, a stop valve, a forward centrifugal pump, a reverse centrifugal pump and a reverse inlet pipe, wherein the forward centrifugal pump and the reverse centrifugal pump are connected in parallel, and a double-way pressurizing process can be realized through controlling the forward centrifugal pump and the reverse centrifugal pump.
Description
Affiliated technical field
The utility model relates to the wheeled two-way pressure device of a kind of moulded coal ducting, can be widely used in ducting moulded coal engineering item, and the pressurized equipment use as the ducting moulded coal belongs to ducting type coal equipment technical field.
Background technology
Before the utility model is made; The two-way pressurization of ducting moulded coal is to accomplish through alternately controlling the valve that is arranged on the rhombus pipeline; This two-way pressuring method needs floor area big, and moulded coal blocks easily, two-way pressure process complicated, has influenced the normal safe operation of pipeline.
Summary of the invention
In order to solve the two-way pressurization problem of ducting moulded coal, improve the two-way pressuring method of existing moulded coal, simplify technological process; Reduce floor area; Guarantee to carry the normal safe operation of moulded coal pipeline, the utility model provides a kind of moulded coal ducting wheeled two-way pressure device, and the wheeled two-way pressure device of this moulded coal ducting is simple in structure; Easy for installation, the two-way pressurization of moulded coal is effective.
The utility model solves the technical scheme that its technical matters adopted: it is made up of forward inlet pipe, blow off valve, charging wheel, expansion tank, shutoff valve, forward centrifugal pump, reverse centrifugal pump and reverse inlet pipe; Wherein the forward centrifugal pump is that install in parallel is installed with reverse centrifugal pump, just can realize two-way pressure process through control forward centrifugal pump and reverse centrifugal pump.
The beneficial effect of the utility model is that the two-way pressurized equipment of moulded coal that can be used for any ducting moulded coal engineering item uses, thereby has reduced floor area, has simplified technological process, has guaranteed the normal safe operation of pipeline.
