includes the first discharging discharging spiral of spiral 41, second 42, oil bath seal connector 43, the outlet and the second discharging spiral of the connection of oil bath seal connector 43 and the first discharging spiral 41 It is described since sealed connecting component includes the first inner ring 431, the first outer ring 432, outside the second inner ring 433, second between 42 entrance Ring 434, the first inner ring 431 and 432 concentric co-axial of the first outer ring are set to the outlet end of the first discharging spiral 41, the second inner ring 433 and 434 concentric co-axial of the second outer ring be set to the arrival end of the second discharging spiral 42, in the second inner ring 433 setting and first Between ring 431 and the first outer ring 432, the second outer ring 434 is set between the first inner ring 431 and the first outer ring 432, the first inner ring 431, the first outer ring 432, the second inner ring 433, be spaced gap between the second outer ring 434, in the second inner ring 433 and the second outer ring Seal oil is full of between 434, one end of the first discharging conveyer 41 is set to outside furnace body 10, and the other end stretches to outer cylinder 11 Also several shovelling plates 112 are arranged in 11 inner wall right end of outer cylinder in inside, and several shovelling plates 112 are distributed on 11 inner wall of outer cylinder, shovelling plate 112 It is set between 11 inner wall of 41 right end of the first discharging spiral and outer cylinder, calcium sulfate slag is sent into inside the first discharging spiral 41, One end of acid inlet tube 30 is set to outside furnace body 10, and the other end stretches to inside outer cylinder 11, and bright sulfur acid is fed through outer cylinder 11 Inside, the second discharging spiral include motor, screw rod, shell, and the shell is hollow cylinder, and motor is arranged outside the shell, One end of screw rod penetrates interior of shell, and the other end is connected to motor, and to be rotated by electric motor driven screw, also sets inside the housing The first sealing plate 421, the first annulus 422, the second annulus 423, third annulus 424 are set, the first sealing plate 421 is set in screw rod outer wall On, and be arranged close to outer casing end, the first annulus 422 and 423 concentric co-axial of the second annulus are fixedly installed on the first sealing plate 421 On side wall, third annulus 424 is fixedly installed on shell end wall, and third annulus 424 is set to the first annulus 422 and the second annulus Between 423, the first annulus 422, the second annulus 423, third annulus 424 have overlapping region in radial direction, so that the first envelope Bending type sealed passage is formed between plate 421 and shell end wall.

Anchor ear ring 132 is an annulus, and the setting of fixed link 131 and anchor ear ring 132 ensure that inner cylinder 12 with outer cylinder first 11 rotations；In addition, the inner wall of anchor ear ring 132 is slidably matched with slideway 122 in the axial direction, the inner wall of anchor ear ring 132 can also be Radial direction is slidably matched with slideway 122, to realize the comprehensive sliding in anchor ear ring 132 and inner cylinder 12 axially and radially direction, When inner cylinder 12 is heated microdilatancy, can micro-shifting is dynamic in the axial direction or even play, the sliding between anchor ear ring 132 and slideway 122 Cooperation, micro-shifting is dynamic thus provides activity surplus, avoid being unable to micro-shifting it is dynamic caused by fixed link 131 and 10 inner wall of furnace body and Fracture or slight crack caused by being rigidly connected between 12 outer wall of fixed link 131 and inner cylinder.

It is compared to directly adopt the mode that fixed link 131 is rigidly connected between inner cylinder 12 and outer cylinder 11, inner cylinder 12 is heated swollen When swollen receipts micro-shifting is moved, 131 both ends of fixed link are all easy to appear the phenomenon that dislocation is broken, and are compared in fixed link 131 and outer cylinder 11 Wall is slidably connected between 12 outer wall of inner cylinder both modes that are rigidly connected, since inner cylinder 12 is set in thermal field, deflection compared with Greatly, it is easier to the case where being broken.Calcium sulfate slag from first discharging spiral 41 to second discharging spiral 42 between transition when, Due to hydrogen also residual fluorinated in slag and sulfuric acid, exist from the first outlet of discharging spiral 41 and entering for the second discharging spiral 42 The risk revealed between mouthful, so while solving the problems, such as leakage after sealing.

Also, the setting of the first inner ring 431 is fallen with inside the second inner ring 433 for stopping the first discharging spiral 41 to export Slag or liquid enter due to intracavitary.

In the second discharging spiral, when screw rod penetrates interior of shell, there are gaps on shell end wall, be easy to cause fluorination The leakage of hydrogen or sulfate liquid, so being embedded between the first annulus 422 and the second annulus 423 using third annulus 424 Mode, form bending type channel, not only increase contact area between three annulus, increase blocking area, and bend Type channel has multiple dead angles, even if there are slags to be leaked into bending type channel interior, since the state of slag is paste, and sulphur Sour calcium slag is easy the moisture absorption, after entering in bent passage, adsorbs the moisture in air, more forms sticky lotion, further fill It is completely bonded in bending type channel, plays the effect of sealed colloid, thoroughly solve the problems, such as leakage.

Further, outer cylinder 11 is axially obliquely installed, inclined direction be tilted down to left end, inner cylinder 12 along It is horizontally arranged.

Further, the length close to the fixed link 131 of 12 left end of inner cylinder is greater than the fixed link 131 close to 12 right end of inner cylinder Length, so that inner cylinder 12 is along horizontally arranged.

The length of the right end overlay segment of the left end and inner cylinder 12 of feed conveyer 20 is 1-2 meters, and the setting of the overlay segment has There is important role, is cold burden since external raw material fluorite enters inside furnace body 10, temperature is very low, and the calcium sulfate slag in furnace Temperature is very high, and the feed direction of anti-slag spiral 121 and the feed direction of feed conveyer 20 in both overlay segments on the contrary, just tie It closes, raw material fluorite and calcium sulfate slag realize preliminary mixing in overlay segment, and then anti-slag spiral 121 continues mixture defeated to right end It send, is fallen from 12 right end port of inner cylinder, fall in inside outer cylinder 11, be further heated, it is outer with the setting that is tilted to the left later The setting of cylinder 11, mixture continuation convey to the right, and reaction is realized inside the outer cylinder 11 below inner cylinder 12, produces calcium sulfate slag And hydrogen fluoride gas, hydrogen fluoride gas are sent along acid inlet tube 30, calcium sulfate slag takes up feeding the first discharging spiral shell by shovelling plate 112 Rotation 41, is sent.

Further, mixing auger blade 123 is set also inside inner cylinder 12, and mixing auger blade 123 is set to inner cylinder 12 In the overlay segment of right end, the width of mixing auger blade 123 is less than the width of the blade of anti-slag spiral 121.Mixing auger blade 123 for by overlay segment fluorite and calcium sulfate slag mix.

Further, the first discharging spiral 41 is spiral propeller, outside the spiral propeller below shovelling plate 112 Wall is open type, and so that calcium sulfate slag enters inside, the outer wall positioned at the inner cylinder 12 of 111 lower section of material copy spoon is also open type, with Enter for calcium sulfate slag.

Further, the shovelling plate 112 is arc panel, so that calcium sulfate slag slides along arc panel to the first discharging spiral 41 It is interior.It is compared to straight panel shovelling plate 112, reduces and the mechanical shock of the first discharging spiral 41 is destroyed.

Module or unit in the utility model embodiment device can be merged according to actual needs, divide and be deleted Subtract.

Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly Interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to this reality The equivalent variations made by novel claim, still falls within the scope of the utility model.
