Description
Technical field
The utility model relates to the coal dust cutting agency in a kind of coal dust load transfer device-coal dust solid pump.
Background technology
Coal turns in oily flow process and uses solid pump as the coal dust pressure delivery device in conversion process, in reciprocating pulverized coal transfer pump, in pulverized coal transfer pump working process, equipment will bear operation pressure, the impact of the power such as deadweight, so need a kind of mechanism of mating with this solid pump load transfer device of design compact, can with the cutting agency of the servo-actuated blanking of pump main body action, the explosion-proof of entirety still can be ensured in the deformation situation that interface is less in motion process, safety and normal work, mechanism solves to be prepared and the coal dust be stored in the feed bin of top, through mechanism, by reciprocal output frequency, for extruding cavity is filled with the coal dust of constant volume.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cutting agency, can with the cutting agency of the servo-actuated blanking of pump main body action, by being stored in the coal dust in the feed bin of top, through mechanism, by reciprocal output frequency, for extruding cavity is filled with the coal dust of constant volume.
For solving the problems of the technologies described above, the utility model adopts following technical scheme, and the cutting agency in coal dust solid pump is applicable to coal dust solid pump, and wherein coal dust solid pump comprises the housing vertically arranged, main driving high-voltage oil cylinder, extrudes piston component etc., cutting agency in coal dust solid pump, comprise servo-actuated cover cylinder, its servo-actuated cover cylinder has some, the upper piston that the lower ending opening of its servo-actuated cover cylinder and coal dust solid pump extrude piston component is connected and fixed, be distributed in the surrounding that extrudes piston component to overlap with casing center to ensure equipment center of gravity or to depart from less, its some servo-actuated cover cylinders converge as aggregate bin in the inside of piston component hollow, its aggregate bin is communicated to the cavity of upper piston bottom, blanking shutoff valve is equipped with between its aggregate bin and upper piston, passage, its servo-actuated cover cylinder converges at coal dust solid pump case top top cover place as distribution hopper.
Preferably, its blanking shutoff valve is fluid-controlled cut-off valve, is connected with main driving high-voltage oil cylinder, up and open with extruding piston component, goes upward to fluid-controlled cut-off valve when limes superiors stops close simultaneously when extruding piston component.
Preferably, its aggregate bin, distribution hopper are all connected with top with the bottom of servo-actuated cover cylinder respectively with pressure tight metal flexible pipe, to ensure that connecting portion can not destroy because of less dislocation or deformation.
Preferably, between its distribution hopper and coal dust storage bin, shutoff valve is housed, under ensureing emergency situations or maintenance situation, closes coal dust supply.
Preferably, its servo-actuated cover cylinder is the telescopic sealing socket join structure of at least two sections of compositions, to meet requirement anti-flaming, explosion-proof in coal dust course of conveying.
The beneficial effects of the utility model are: mechanism is compact, can with the cutting agency of the servo-actuated blanking of pump main body action, still can ensure overall explosion-proof, safety in the deformation situation that interface is less in motion process and normally work, through mechanism, by reciprocal output frequency, provide the coal dust of constant volume.
