Abstract
The utility model discloses a jet type power transfer pump, comprising an enclosed air chamber. One end of the enclosed air chamber is provided with a material-gas mixed transfer pipe extending into the enclosed air chamber, the material-gas mixed transfer pipe is hermetically connected with the enclosed air chamber, the other end is equipped with a material suction pipe, the material suction pipe extends into the encloses air chamber, the material suction pipe is hermetically connected with the enclosed air chamber, the material suction pipe corresponds with the material-gas mixed transfer pipe, the diameter of the material-gas mixed transfer pipe is slightly larger than that of the material suction pipe, and the enclosed air chamber is provided with a pressure air inlet pipe. The utility model is not easy to damage, the transfer effect is good, and the structure is simple and compact.
Description
Technical field
The utility model relates to powdery, granular substance material conveying device, especially a kind of jet-type powder transfer pump.
Background technique
Traditional powder feedway is to adopt blower and pipeline that powder is drawn to come, and at pipeline filter is set and powder is filtered powder is fallen carry the destination, owing to can't filter out fully through powder behind the filter, there is the dust of part to enter into blower fan, make blower fan fragile, reduce the working life of blower fan greatly.Venturi effect is meant that when obstacle was crossed in wind, air pressure was relatively low near port above the lee face of obstacle, thereby produces suction-operated and cause flowing of air.
The model utility content
The utility model purpose provide a kind of not fragile, powder conveying is effective, the jet-type powder transfer pump of compact structure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of jet-type powder transfer pump comprises closed air chamber, end at closed air chamber is provided with material gas mixing delivery pipe, this material gas mixing delivery pipe reaches in the closed air chamber, material gas mixing delivery pipe and closed air chamber are tightly connected, the other end is provided with suction tube, this suction tube reaches in the closed air chamber, suction tube and closed air chamber are tightly connected, described suction tube is corresponding with material gas mixing delivery pipe, greater than the suction tube diameter, described closed air chamber is provided with the pressure breathing pipe to material gas mixing delivery pipe at the corresponding part pipe diameter.
Described material gas mixing delivery pipe is consistent in the corresponding part shape with suction tube.
The input end of described material gas mixing delivery pipe is the venturi inlet of taper, and and then one section of the venturi inlet is column tube, at one section expanding duct for the venturi outlet of column tube output terminal.
The conical surface of the output terminal outer tube wall of described suction tube for matching with the venturi inlet.
Described suction tube adopts fine thread to be connected with closed air chamber.
After said structure is adopted in this practicality, two ends by closed air chamber are provided with corresponding material gas mixing delivery pipe and suction tube, material gas mixing delivery pipe and suction tube all reach in the closed air chamber, material gas mixing delivery pipe at the pipeline of corresponding part greater than the suction tube pipeline, establish annular space Venturi nozzle of formation in their corresponding part, therefore, behind the pressurized air process annular space Venturi nozzle, the mouth of pipe at material gas mixing delivery pipe forms negative pressure region, negative pressure region can be carried so that material enters to form in the material gas mixing delivery pipe along suction tube, because jet powder pump when conveying material, does not have any transmission part, therefore when conveying has abrasion powder or granule, can reduce wearing and tearing to a great extent to equipment, avoid directly using blower fan, dust does not directly contact with blower fan, improves blower fan working life; Suction tube adopts fine thread to be connected with closed air chamber, can guarantee that on the one hand the pressurized air in the air chamber can not reveal, can realize suction tube and the fine setting of expecting gap between the gas mixing delivery pipe on the other hand, be the size of adjustable annular space Venturi nozzle, and then realize accurately regulating the effect of air inflow; The input end of gas mixing delivery pipe is taper venturi inlet, one section at venturi inlet output terminal is column tube, one section at the column tube output terminal is trumpet-shaped expanding duct, the conical surface of the output terminal outer tube wall of described suction tube for matching with the venturi inlet, it is more smooth and easy that the pressurized air that can guarantee air chamber enters the annular space Venturi nozzle, expanding duct through punishment in advance gas mixing delivery pipe, gas velocity and particle speed all can reduce and this moment zone of positive pressure pressure can guarantee that particle overcomes resistance and moves forward, realize that powder is in ducted conveying.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model structural drawing.
Among the figure: 1 closed air chamber, 2 material gas mixing delivery pipes, 21 venturi inlet, 22 column tubes, 23 extension mouths, 3 suction tubes, 31 conical surfaces, 4 pressure breathing pipes, 5 annular space Venturi nozzles.
Embodiment
Shown in Figure 1, jet-type powder transfer pump of the present utility model comprises closed air chamber 1, wherein the end at closed air chamber 1 is provided with material gas mixing delivery pipe 2, this material gas mixing delivery pipe 2 reaches in the closed air chamber 1, material gas mixing delivery pipe 2 is tightly connected with closed air chamber 1, the other end is provided with suction tube 3, this suction tube 3 reaches in the closed air chamber 1, suction tube 3 is tightly connected with closed air chamber 1, described suction tube 3 is corresponding with material gas mixing delivery pipe 2, greater than suction tube 3 diameters, described closed air chamber 1 is provided with pressure breathing pipe 4 to material gas mixing delivery pipe 2 at the corresponding part pipe diameter.Described material gas mixing delivery pipe 2 is consistent in the corresponding part shape with suction tube 3.The input end of described material gas mixing delivery pipe 2 is the venturi inlet 21 of taper, and and then one section of venturi inlet 21 is column tube 22, at one section expanding duct 23 for the venturi outlet of column tube 22 output terminals.The output terminal outer tube wall of above-mentioned suction tube 3 is and venturi inlet 21 conical surfaces that match 31.Described suction tube 3 adopts fine thread to be connected with closed air chamber 1.The utility model has changed traditional powder feedway and has adopted blower fan to carry powder, adopts the compressed air delivery powder.Because the utility model when conveying material, does not have any transmission part, therefore when conveying has abrasion powder or granule, can reduce wearing and tearing to a great extent to equipment, solve direct use blower fan and carried the problem that blower fan is perishable.
