In 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 the drawings and specific embodiments, the present invention is described further:
As shown in Figures 1 and 2, a kind of uranium converter feeding unit, comprises support 1, and this support 1 is for placing charging hopper 2.For the ease of movement, can below support 1, universal wheel be installed.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, is provided with spiral pushing device in cylinder.Stretch out outside support 1 one end of feeding screw 3, on the feeding screw 3 stretching out outside support 1 with sealing-ring 4; 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 pushed feeding screw 3 one end with sealing-ring 4 to from charging hopper 2.In feeding screw 3, also comprise heating unit in addition, for to heating at the material of feeding screw 3.Described heating unit can be any heating unit of the prior art, for example nichrome wire.
As shown in Figure 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 turbination container, and the main shaft of whipping appts 6 stretches into downwards in turbination container, is fixedly connected with two agitating plates 10 on this main shaft.At the end face of turbination container, opening for feed 7 is set, the internal communication of this opening for feed 7 and turbination container.End face at turbination container also arranges surveillance mirror 8, and the end face of surveillance mirror 8 is transparent glass, and staff can observe by surveillance mirror 8 inside of turbination container.Be provided with inlet mouth 9 in the top position of the sidewall of turbination container, this inlet mouth 9 is communicated with turbination internal tank.By the position of bottom surface, material level detector 11 is set at the sidewall of turbination container, this material level detector 11 can alarm in the time detecting in turbination container that material is very few.Whipping appts 6 main shafts can increase bottom metal band, further guarantee that material is discharged on feeding screw 3 uniformly.
Working process of the present invention is roughly as follows: before converter heats up, this device need be connected with converter, and material is filled on feeding screw 3, start reinforced work after intensification.Needs by this uranium converter feeding unit in adding materials in converter, first feeding screw 3 is connected with the opening for feed of converter, 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 sealed and is communicated with opening for feed 7, and opening for feed 7 is equipped with the ball valve of using as switch.When above-mentioned connection all completes and checks in the situation of good seal, open ball valve, the substandard product in charging basket is injected to the turbination container of charging hopper 2, injection process is observed injection process and injection capacity by surveillance mirror 8.The substandard product capacity injecting should fill turbination container as far as possible, but can not shelter from inlet mouth 9.After injection completes, close ball valve, open nitrogen source of the gas, nitrogen is entered in turbination container by inlet mouth 9, certainly preferably by after nitrogen heating passing in turbination container.Open whipping appts 6 simultaneously, make whipping appts 6 drive agitating plate 10 to rotate, uranium hexafluoride is stirred in turbination container, and guarantees that discharging is even.Open motor 5, make the spiral pushing device work in feeding screw 3, the material of discharging in charging hopper 2 is promoted to sealing-ring 4 directions; Open the heating unit in feeding screw 3 simultaneously, the defective material in feeding screw 3 is heated and makes its temperature remain on 120 degree left and right.Substandard product enters conversion reaction in furnace by feeding screw 3.Along with material is constantly injected into converter, the material in uranium converter feeding unit constantly reduces, and when inventory is during lower than the height of material level detector 11, material level detector 11 is reported to the police, and reminds staff to continue to add materials.
