[0030] Please refer to Figures 1-8 The existing alloy bar blank forming screening device, in the screening process, the raw materials are accumulated on the screening structure, the screening structure is easy to be blocked, and it is not convenient to unload the raw materials left on the screening structure. In order to solve this technical problem, the embodiment discloses the following technical content;
[0031] A kind of alloy bar blank forming screening device for preventing accumulation, including device shell 1, first screening assembly and second screening assembly, the right end of device shell 1 is equipped with suction pipe 17, control valve is installed in the inside of suction pipe 17, suction pipe 17 outer high-pressure pump, for absorbing device shell 1 inside gas before screening;
[0032] First screening assembly is installed in the upper part of the inside of device shell 1, the left end of device shell 1 is equipped with feed inlet, the left end of device shell 1 is clamped and installed with cover 9, cover 9 is clamped at feed inlet, when needing to feed, cover 9 is removed from the feed inlet of device shell 1, alloy bar manufacturing raw materials are fed into the inside of first screening assembly from feed inlet;
[0033] First screening assembly includes receiving ring 2, motor 3, screening bucket 4, baffle 5, cover plate 6, wire rod 7, connecting wire 8 and second cleaning frame 11, the inside right wall of device shell 1 is fixed with receiving ring 2, the right side of device shell 1 is fixed with motor 3, the output end of motor 3 is fixed with screening bucket 4, and the outer end of screening bucket 4 is rotatably connected with baffle 5, the outside of baffle 5 is provided with cover plate 6, the inside surface of screening bucket 4 is fixed with wire rod 7, the outside of wire rod 7 is coiled with connecting wire 8, one end of connecting wire 8 away from wire rod 7 is fixedly connected with baffle 5, the outside surface of screening bucket 4 is fixed with second cleaning frame 11 for avoiding the blockage of second screening assembly;
[0034] Since the left end of device shell 1 is equipped with feed inlet, the left end of screening bucket 4 is located in feed inlet, the transverse center line of cover 9 coincides with the transverse center line of screening bucket 4, alloy bar manufacturing raw materials are fed into the inside of screening bucket 4, then cover 9 is clamped into feed inlet, at this time, first cleaning frame 10 on cover 9 is attached to the inside surface of screening bucket 4, the control valve in the inside of suction pipe 17 is opened, the inside air of device shell 1 is removed by high-pressure pump, so that low-oxygen vacuum environment is formed in device shell 1, the connection between cover 9, side plate 12 and blocking plate 16 and device shell 1 will not leak air, the output shaft of motor 3 is connected with device shell 1 through rotary sealing ring.
[0035] The motor 3 is started, and the motor 3 drives the screening barrel 4 to rotate to screen the materials, and the materials with a particle size smaller than the screen hole of the screening barrel 4 fall on the second screening assembly. During the rotation of the screening barrel 4, the first cleaning frame 10 cleans the inner side surface of the screening barrel 4, so as to avoid the blocking of the materials, and the rotation of the screening barrel 4 can avoid the accumulation of the raw materials;
[0036] The second screening assembly comprises a side plate 12 and an arc-shaped screen plate 13. The arc-shaped screen plate 13 is fixed to the right side surface of the side plate 12. The side plate 12 is connected to the device shell 1 in a clamping manner. The alloy rod manufacturing raw materials flow out of the screening barrel 4 and fall on the arc-shaped screen plate 13. The alloy rod manufacturing raw materials are screened again through the arc-shaped screen plate 13. The alloy rod manufacturing raw materials with a particle size smaller than the screen hole of the arc-shaped screen plate 13 fall on the bottom end of the inside of the device shell 1 and move downward along the guide plate 14. The second cleaning frame 11 rotates with the screening barrel 4. When the second cleaning frame 11 is located below, the outer side surface of the second cleaning frame 11 is attached to the upper surface of the arc-shaped screen plate 13.

[0037] The bottom surface of the device shell 1 is fixed with an electric telescopic rod 15. The output end of the electric telescopic rod 15 is fixed with a blocking plate 16. When it is needed to unload the materials, the blocking plate 16 leaves the material outlet at the bottom end of the device shell 1 under the action of the electric telescopic rod 15. The raw materials with the smallest particle size flow out of the material outlet at the bottom end of the device shell 1 and are pulled out of the side plate 12 and the arc-shaped screen plate 13. Then, the raw materials left on the arc-shaped screen plate 13 can be taken out.
[0038] When the baffle 5 is rotated to the lowermost position, the cover 9 is removed. The worker inserts the hand into the inside of the screening barrel 4, takes down the connecting wire 8 from the wire rod 7, rotates the cover plate 6, and rotates the cover plate 6 because the inner end of the cover plate 6 is located in the inside of the screening barrel 4. Thus, the worker can rotate the cover plate 6. The baffle 5 loses the block of the cover plate 6. The baffle 5 is flipped downward. Thus, the raw materials left in the inside of the screening barrel 4 fall down. The raw materials can fall on the arc-shaped screen plate 13. The raw materials left in the inside of the screening barrel 4 can be taken out by pulling out the arc-shaped screen plate 13. The raw materials left in the inside of the screening barrel4 can also fall to the bottom end of the inside of the device shell 1 and flow out of the material outlet at the bottom end of the device shell 1 before the baffle 5 is opened.
[0039] When it is needed to retract the baffle 5, the worker inserts the hand into the inside of the screening barrel 4, winds the connecting wire 8 on the wire rod 7, and retracts the baffle 5. Then, the cover plate 6 is rotated to block the baffle 5.
