Description of drawings
Fig. 1 is the structural representation of uranium receiver feeding unit provided by the invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of charging hopper.
Among the figure: 1. support, 2. charging hopper, 3. feeding screw, 4. sealing-ring, 5. motor, 6. whipping appts, 7. opening for feed, 8. surveillance mirror, 9. inlet mouth, 10. agitating plate, 11. material level detectors.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further explanation:
As attach illustrated in figures 1 and 2ly, and a kind of uranium receiver feeding unit comprises support 1, this support 1 is used for placing charging hopper 2.For the ease of moving, can be below support 1 the installation universal wheel.Fixed installation charging hopper 2 on support 1.Charging hopper 2 belows are communicated with feeding screw 3 sealings.Feeding screw 3 is long tubular, in tube, is provided with spiral pushing device.One end of feeding screw 3 stretches out outside the support 1, has sealing-ring 4 on the feeding screw 3 outside stretching out support 1; The other end of feeding screw 3 is connected with motor 5, and motor 5 can drive feeding screw 3 screw rotation, and the feeding screw 3 of screw rotation can be with pushing the end that feeding screw 3 has sealing-ring 4 to from charging hopper 2.Also comprise heating unit in the feeding screw 3 in addition, be used for the material at feeding screw 3 is heated.Described heating unit can be any heating unit of the prior art, for example nichrome wire.
Shown in accompanying drawing 3, charging hopper 2 comprises the turbination container of hollow, and the bottom of this container is communicated with feeding screw 3 sealings.Whipping appts 6 is set above the turbination container, and the main shaft of whipping appts 6 stretches into downwards in the turbination container, on this main shaft, is fixedly connected two agitating plates 10.End face at the turbination container is provided with opening for feed 7, the internal communication of this opening for feed 7 and turbination container.End face at the turbination container also is provided with surveillance mirror 8, and the end face of surveillance mirror 8 is a transparent glass, and the staff can be through the inside of surveillance mirror 8 observation turbination containers.Be provided with inlet mouth 9 in the position that the sidewall of turbination container leans on, this inlet mouth 9 is communicated with the turbination internal tank.Sidewall at the turbination container leans on the position of bottom surface that material level detector 11 is set, and this material level detector 11 can alarm when material is very few in detecting the turbination container.Whipping appts 6 main shafts can increase metal band bottom, guarantee that further material is discharged on the feeding screw 3 uniformly.
Working process of the present invention is roughly following: before receiver heats up, need this device is connected with receiver, and material is filled on the feeding screw 3, begin reinforced work after the intensification.When needs add materials in receiver through this uranium receiver feeding unit, at first feeding screw 3 is connected with the opening for feed of receiver, and seals with sealing-ring 4; Nitrogen source of the gas and inlet mouth 9 are tightly connected; The charging basket that substandard product is housed is communicated with opening for feed 7 sealings, and opening for feed 7 is equipped with the ball valve of using as switch.Under the situation of whole completion of above-mentioned connection and inspection good seal, open ball valve, with the turbination container of the injection of the substandard product in charging basket charging hopper 2, injection process is passed through surveillance mirror 8 and is observed injection process and injection capacities.The substandard product capacity that injects should be filled with the turbination container as far as possible, but can not shelter from inlet mouth 9.Close ball valve after injecting completion, open the nitrogen source of the gas, make nitrogen pass through inlet mouth 9 and get in the turbination containers, preferably nitrogen is heated the back in feeding the turbination container certainly.Open whipping appts 6 simultaneously, make whipping appts 6 drive agitating plate 10 and rotate, uranium hexafluoride is stirred in the turbination container, and guarantees that discharging is even.Open motor 5, make the spiral pushing device work in the feeding screw 3, the material of discharging in the charging hopper 2 is promoted to sealing-ring 4 directions; Open the heating unit in the feeding screw 3 simultaneously, to the defective material in the feeding screw 3 heat make its temperature remain on 120 the degree about.Substandard product gets into the receiver internal reaction through feeding screw 3.Along with material constantly is injected into receiver, the material in the uranium receiver feeding unit constantly reduces, and when inventory was lower than the height of material level detector 11, material level detector 11 was reported to the police, and reminded the staff to continue to add materials.
