Description
Technical field
The present invention relates to a kind of stopper, relate in particular to a kind of stopper that is used for lithium liquid conveyance conduit.
Background technique
In the refining production process of lithium, lithium is remained on liquid state and transports by vacuum pipe is more common a kind of mode, but usually is faced with the problem of adjusting the lithium flow quantity in the production process, particularly the problem that flows by lithium liquid.Traditional valve is all inapplicable as a kind of lithium liquid pipeline transport stopper, for example, the needle type valve of using in the lithium liquid pipeline transport exists following problem now: 1, the junction of lithium liquid pipeline and needle type valve exists nonsynchronous problem of expanding with heat and contract with cold, poor sealing performance, and lithium liquid must be avoided moisture in process of production; 2, lithium liquid meeting etch needle type valve causes needle type valve to lose efficacy, and changes the continuous production that needle type valve seriously influences factory continually.
The applicant's utility model application the preceding discloses a kind of lithium liquid stop valve (application number CN201020162058.3), include one section metallic conduit of carrying lithium liquid, electric heating wire is arranged on the metallic conduit outer wall around the home, and this electric heating wire top is provided with can spray the also coolant outlet of cool metal pipeline.Though this technological scheme has solved the sealing and the durability issues of stop valve, but himself there is this new technical problem simultaneously, when electric heating wire adds the lithium piece of thermocoagulation, melt at first in the place of lithium piece and tube contacts, this moment, the lithium piece was washed away by lithium liquid, causes the provisional obstruction of pipeline easily under the pressure of lithium liquid promotes, particularly, cause the flow of lithium liquid to be difficult to better controlled like this at the turning of lithium liquid pipeline.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple structure, not only can finish pipeline lithium liquid by but also the lithium liquid stopping device that can also avoid the provisional obstruction of lithium piece durable in use.
In order to solve the problems of the technologies described above, the invention provides a kind of lithium liquid stopping device, include a stainless steel extra heavy pipe, a stainless steel tubule, be provided with the stainless steel chimney filter of stainless steel filter screen in pipe, the stainless steel tubule is enclosed within the stainless steel extra heavy pipe, the length of stainless steel tubule is longer than the stainless steel extra heavy pipe, stainless steel extra heavy pipe two ends sealing and fixing is on stainless steel tubule outer wall, the stainless steel extra heavy pipe is provided with water intake and water outlet, the flow through outlet of stainless steel tubule of lithium liquid is connected with the stainless steel chimney filter, on the stainless steel tubule outer wall that socket-connects with the stainless steel extra heavy pipe electric heating wire is arranged around the home, the filter screen front of stainless steel chimney filter also has electric heating wire around the home.
When needs end lithium liquid, cooling water is introduced from water intake, draw from water outlet, cooling water and the heat exchange of stainless steel tubule, lithium liquid in the tubule is cooled off rapidly, thereby reach the purpose by lithium liquid, cooling water is uninterrupted, thereby can keep the lithium piece not melt the purpose that reaches remain off lithium liquid.When needs clearance lithium liquid, stop to introduce cooling water, electric heating wire is connected in the cooling water emptying that flows away, electric heating wire heating stainless steel tubule surface, the lithium piece is slowly melted, after lithium piece and the disengaging of stainless steel tubule internal surface, the lithium BOB(beginning of block) flows, and this moment, the lithium piece was stopped by the filter screen on the stainless steel chimney filter, and outside filter screen, melt fast under the heat effect of electric heating wire, this moment, lithium liquid began normal flowing.
Adopt the lithium liquid stopping device of the technical program to have following advantage 1, owing to do not use traditional stop valve, avoided the sealing problem of stainless steel pipeline and metal stop valve junction; 2, owing to there is not spool, avoided the valve invalidation problem that causes because of the etch of lithium liquid; 3, because the filter screen front of stainless steel chimney filter is provided with electric heating wire, in interception lithium piece, quicken the thawing of lithium piece, avoid lithium piece surface to melt the back and flowed the provisional obstruction that causes at lithium liquid pipeline turning along the stainless steel tubule.
Further, to the obstruction of pipeline, the filter screen place of described stainless steel chimney filter is provided with the long-pending spherical cavity of increasing section when melting in order to reduce the lithium piece.
Further, in order to improve the sensitivity of stop valve, strengthen the lithium metal that solidifies and the combination force of pipeline, improve the area of contact of resistance wire and pipeline simultaneously, the convenient electric heating wire that twines is limited to the stainless steel tubule that electric heating wire locates around the home and the outer surface of stainless steel chimney filter and is set to shape of threads.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention lithium liquid stopping device.
Embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1, the invention provides a kind of lithium liquid stopping device, include a stainless steel extra heavy pipe 1, a stainless steel tubule 2, a stainless steel chimney filter 3 that is provided with stainless steel filter screen 31, wherein stainless steel extra heavy pipe 1 and stainless steel tubule 2 connect together, stainless steel extra heavy pipe 1 sealed at both ends is fixed on the outer wall of stainless steel tubule 2, stainless steel extra heavy pipe 1 is provided with water intake 11 and water outlet 12, wherein intake pipe 11 is arranged on stainless steel extra heavy pipe 1 upside, water outlet 12 is arranged on stainless steel extra heavy pipe 1 downside, the flow through outlet and the stainless steel chimney filter 3 of stainless steel tubule 2 of lithium liquid is tightly connected together, stainless steel tubule 2 tube walls in the stainless steel extra heavy pipe 1 are set to shape of threads, electric heating wire 21 is arranged on its outer wall around the home, expand and form spherical cavity in filter screen 31 places of stainless steel chimney filter 3, filter screen 31 is connected in the spherical cavity, and filter screen 31 fronts of stainless steel chimney filter 3 also are provided with electric heating wire 21.
