Embodiment
Below in conjunction with accompanying drawing, the utility model is done further description.
Embodiment 1: this dry powder pump device, this dry powder pump device, comprises feed-pipe 10, hydraulic drive cylinder 1, hydraulic stem 2, intermediate chamber 3, middle connecting rod 5, powder pressurized cylinder 4, piston 6, feeding discharging material valve seat 7, feed valve 9, blow-off valve 11, feed-pipe 10 and discharging pipe 13; Hydraulic drive cylinder 1, intermediate chamber 3, powder pressurized cylinder 4, feeding discharging material valve seat 7 connect fastening successively; The feed valve 9, the blow-off valve 11 that are arranged on feeding discharging material valve seat 7 are connected with feed-pipe 10, discharging pipe 13 respectively; Having the delivery device that hydraulic stem 2, middle connecting rod 5 and piston 6 are linked in sequence and form in powder pressurized cylinder 4 on medullary ray, piston 6 and feed valve 9 and blow-off valve 11 combine, it is achieved the suction of pulverulent material and positive delivery.
Described feed valve, blow-off valve adopt sluice valve or cone valve, hard sealing of floating is adopted to realize closedown and the conducting of rated pressure pulverulent material, realizing conducting or the cut-out of dry material under 5 MPa states, its type of drive can adopt hydraulic pressure or machinery electric pushrod mode.
Fig. 3 is the delivery system figure that dry powder pump device is formed. Powder enters dry powder pump e Foerderanlage from bottom, normal pressure powder material storehouse through the outlet of normal pressure powder material storehouse, feed-pipe, feed valve, it is that negative pressure sucks that powder enters dry powder pump device, pressurize to powder through dry powder pump piston, force to push powder and set up the pressure overcoming high-pressure delivery storehouse pressure and transport pipe on-way resistance, be then delivered to high pressure feed hopper through blow-off valve, discharge pipe.
Embodiment 2: Fig. 2 is hydraulic drive double plunger powder pumps, and two hydraulic drive cylinders realize being connected by closed circuit at rod chamber. Its main body comprises feed-pipe, hydraulic drive cylinder, hydraulic stem, intermediate chamber, middle connecting rod, powder pressurized cylinder, piston, feeding discharging material valve and discharging pipe.
