Description
Technical field
The utility model relates to a kind of tremie pipe, particularly a kind of tremie pipe being applicable to LF refining furnace.
Background technology
Tremie pipe is used for furnace charge, in LF refining furnace, owing to constantly rubbing between raw material and the tube wall of tremie pipe, is inevitably damaged, thus needs to repair or replace tremie pipe through tremie pipe after a period of time.Under the prior art, LF refining furnace is one-piece construction, and need cutting carrying out repair welding when maintenance, replacing, complicated operation also exists potential safety hazard.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of a kind of segment type tremie pipe with sleeve pipe easy to maintenance.
The technical scheme in the invention for solving the technical problem is: a kind of segment type tremie pipe with sleeve pipe, is characterized in that: comprise the straight tube, sleeve pipe, bend pipe and the stove that are linked in sequence and emit pipe; Be respectively equipped with two sections of screw threads that rotation direction is contrary inside sleeve pipe front and back end, one end that described straight tube, bend pipe are connected with sleeve pipe is respectively equipped with the outside screw adapted with described sleeve pipe internal thread, and sleeve pipe is connected with bend pipe with straight tube respectively by screw thread; Be provided with turning in the middle of the bend pipe stated, corner is positioned at stove and emits directly over opening for feed, and the other end of bend pipe straight down; Described stove emits Guan Yulu to emit opening for feed to be fixedly connected, and stove emits the internal diameter of pipe to equal the external diameter of described bend pipe lower end, and bend pipe lower end is inserted into stove and emits in pipe; Described stove emits inside pipe and is provided with a circle groove, is provided with sealing-ring in groove.
The internal diameter of above-mentioned sleeve pipe is equal to or less than the internal diameter of bend pipe.
Compared with prior art, the utility model has following outstanding beneficial effect:
1, keep in repair, change conveniently;
2, can not tremie pipe be collided when water cooled cover rises, eliminate potential safety hazard;
3, interface sealing gland, prevent the pollution of the environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises the straight tube 1, sleeve pipe 2, bend pipe 3 and the stove that are linked in sequence and emits pipe 5.
Be respectively equipped with two sections of screw threads that rotation direction is contrary inside sleeve pipe 2 two ends, one end that described straight tube 1, bend pipe 3 are connected with sleeve pipe 2 is respectively equipped with the outside screw adapted with described sleeve pipe 2 internal thread, and sleeve pipe 2 is connected with bend pipe 3 with straight tube 1 respectively by screw thread.Because sleeve pipe 2 front and back end thread rotary orientation is contrary, when disassembled, front and back coupling end can be pulled down by revoling tube 2 simultaneously.
Be provided with turning in the middle of described bend pipe 3, corner is positioned at stove and emits directly over 4 opening for feeds, and the other end of bend pipe 3 straight down.Described stove emits pipe 5 and stove to emit 4 opening for feeds to be fixedly connected, and stove emits the internal diameter of pipe 5 to equal the external diameter of described bend pipe 3 lower end, and bend pipe 3 lower end is inserted into stove and emits in pipe 5.
Described stove emits inside pipe 5 and is provided with a circle groove, is provided with sealing-ring 4, emits the gap between pipe 5 to seal bend pipe 4 and stove by sealing-ring 4, prevent furnace gas, dust from overflowing, protection of the environment in groove.
The internal diameter of described sleeve pipe 2 is equal to or less than the internal diameter of bend pipe 3, prevents material to be blocked in the junction of sleeve pipe 2 and bend pipe 3, results in blockage.
In prioritization scheme, described stove emits the groove of pipe 5 to be provided with inlet mouth, and the groove described in inlet mouth the inner is communicated with, outer end connects inlet pipe interface, and this interface can connect the diffusers such as air pump.When sealing-ring 4 lost efficacy or resistance to air loss is inadequate, that can meet an urgent need was inflated in groove by inlet pipe, thus was emitted by stove the gap between pipe 5 and bend pipe 3 to carry out " sealing gland ".
The speed can improve maintenance by the utility model, changing, originally changes tremie pipe and about needs 30-60min, about need 10-20min after improvement; During maintenance, do not need integral replacing tremie pipe, only middle interconnecting piece need be divided and upwards promote or remove, convenient and swift during process; Water cooled cover can not collide tremie pipe when rising, and eliminates potential safety hazard.
It should be noted that; particular of the present utility model has been described in detail the utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
