Abstract
The utility model discloses an automatic powder sprayer comprising a material hopper, a spiral conveying rod positioned below the material hopper, a discharge chamber arranged at one end of the spiral conveying rod and a discharge pipe arranged at the bottom of the discharge chamber. The automatic power sprayer is characterized in that the spiral conveying rod is obliquely arranged, and the included angle Alpha between the axis of the spiral conveying rod and the horizontal plane is in the range of 15-30 degrees; and the spiral conveying rod is driven by a driving motor which is adjusted by a frequency converter. The automatic powder sprayer can effectively avoid air reversing during production, and the modeling powder supply is more uniform.
Description
Technical field
The utility model relates to a kind of automatic powder spraying machine, is applied to the mould powder feed system of DN100～300 ductile iron pipe centrifuges.
Background technology
At present, the nodular cast iron pipe centrifuge has the following disadvantages: 1) once supply the powder amount less, the screw rod diameter is generally 16mm, and the cast iron pipe that diameter is big is not enough a working cycles internal mold powder amount when producing, and needing increases a working cycles, and efficient is low; 2) feed is inhomogeneous, and because of the hydraulic motor rotating speed is subjected to the hydraulic system pressure influence of fluctuations, when main frame was up, the main frame walking was fast, and mould powder supply should be big more, but actual hydraulic pressure system pressure step-down, mould powder supply is more little on the contrary; 3) often have the inverted ventilation phenomenon, influence is produced.
The utility model content
The technical problems to be solved in the utility model provides a kind of automatic powder spraying machine, and it can effectively avoid inverted ventilation, and mould powder supply is even.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of automatic powder spraying machine, it comprises hopper, be positioned at the hopper below spiral conveyor rod, be arranged at the discharge nozzle that feed bin and be located at out the feed bin bottom of spiral conveyor rod one end, its key technology is that described spiral conveyor rod is obliquely installed, and the angle α of the axis of spiral conveyor rod and horizontal plane is 15 °～30 °.
Preferably, the angle α of the axis of spiral conveyor rod and horizontal plane is 30 °.
Preferably, above-mentioned spiral conveyor rod drives by the drive motors by Frequency Converter Control, and the power shaft of spiral conveyor rod connects with the output shaft of drive motors by coupling band; This coupling band is an integral sleeve, and its right-hand member connects with the output shaft of drive motors by key, and its left end connects with the power shaft of spiral conveyor rod by key.
Preferably, above-mentioned helical feed shank diameter is 40mm.
Preferably, above-mentioned hopper is communicated with by telescopic tube with spiral conveyor rod.
Adopt the beneficial effect that technique scheme produced to be: 1, spiral conveyor rod is for being obliquely installed, and mould powder degree of packing in the helical feed process is improved, can effectively avoid because of discharge bucket blast height make wind from discharging opening instead to going out feed bin.
2, drive unit changes motor-driven into by fluid motor-driven, and by the Frequency Converter Control motor, thereby can reach rational feed amount according to main frame walking speed control motor speed.
3, screw rod diameter overstriking, the mould powder supply in a working cycles increases, and one time cloth can satisfy technological requirement, enhances productivity.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, this automatic powder spraying machine is provided with a hopper 1, hopper 1 below is provided with spiral conveyor rod 12, hopper 1 is communicated with by telescopic tube 2 with spiral conveyor rod 12, the mould powder is transported to spiral conveyor rod 12 by telescopic tube 2, the discharging position of spiral conveyor rod 12 left ends is provided with out feed bin 10, under the promotion of spiral conveyor rod 12, the mould powder is transported to out feed bin 10, go out feed bin 10 bottoms and be provided with discharge nozzle 11, discharge nozzle 11 1 ends are provided with air inlet, the mould powder is transported to appointed part by the road from discharging opening 15 under the promotion of wind, this spiral conveyor rod 12 has certain angle α with horizontal plane, can effectively avoid inverted ventilation in the production.In the real work, effect was better when the axis of spiral conveyor rod 12 and the angle of horizontal plane were 30 °.It is 40mm that the diameter of spiral conveyor rod 12 is increased by original 16mm, and diameter is bigger, makes a cloth amount strengthen, and carries air quantity to increase greatly in the unit interval, can well satisfy the distributing technique requirement that bassoon is produced.
