Description

Special pipe for electric heating concentration tank cover

Technical Field

The utility model relates to an electric heating concentration device used in the copper electrolysis liquid purification process, in particular to a special pipe for a cover of an electric heating concentration tank.

Background

The electrothermal concentrator is one of the important devices in the wet smelting liquid-cleaning process, especially in the copper electrolysis liquid-cleaning process, and is characterized by that it utilizes the heat effect produced when the current is passed through the acidic conductive liquid to heat the solution, so that it can be evaporated and concentrated, and can be crystallized, filtered and can obtain the final product copper sulfate. The optimum heating temperature for evaporative concentration is 170 deg.C, but at this high temperature the SO in the electrolyte is present₄ ^2-Has extremely strong corrosivity, and lead must be lined on the wall, bottom and cover of the electrolytic tank for containing the electrolyte under the condition of sealing the container to resist high-temperature SO₄ ^2-Corrosion of (2).

Because of its high density and low hardness, lead must line the steel envelope to develop its corrosion resistance characteristics. The special pipe for the tank cover matched with the eyelet is welded and fixed with the eyelet, and on the basis of the same reason, the anti-corrosion measure must be made at the welding matching position of the eyelet and the special pipe for the tank cover, otherwise, once the weak anti-corrosion position is corroded, the whole tank cover is completely scrapped. Because the aperture size of the pipe is limited and the pipe wall is curved, the traditional special pipe for the trough cover of the electric heating concentration trough consists of a steel outer wall layer and a lead layer from outside to inside, because the lead layer for corrosion prevention in the special pipe cannot be fixed on the steel outer pipe wall by adopting a lead lining process, only a lead lining process can be adopted, but the lead lining process causes no definite fixed point between the lead layer and the steel outer wall layer, and the lead layer is directly contacted with high-temperature electrolyte steam, the lead layer is collapsed due to gravity under long-time high temperature due to the characteristics of high lead density and low hardness, particularly, the steam exhaust pipe on the trough cover is arranged in the horizontal direction, the special pipe blockage phenomenon is more easily caused, the trough cover and the trough body are closed in the production process, the electrolyte in the trough can overflow due to the blockage of the special pipe, and safety accidents are easily caused; the special pipe is welded and fixed on the tank cover, so that the tank cover is inevitably scrapped due to blockage of the special pipe, and economic loss is caused; reinstallation of the slot cover also affects production efficiency.

Chinese patent document CN201120052003.1 discloses a special pipe for a cover of an electric heating concentration tank, which effectively increases the corrosion resistance by adding an asbestos layer. However, the asbestos layer is difficult to replace and slow to construct, and once the porcelain tube layer is damaged, long time is needed for replacement, so that production is affected.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

Example 1

As shown in fig. 1 and 2, the tube wall of the tube dedicated for the trough cover of the electric heating concentrated trough comprises a first lead layer 7, a steel outer wall layer 6, a second lead layer 5, an asbestos layer 4 and a porcelain tube layer 3 from outside to inside, and is characterized in that: the asbestos layer 4 is formed of asbestos tiles 401 having corrugated cross-sections. The asbestos tile 401 in the corrugated shape reduces the contact area with the second lead layer 5 and the porcelain tube layer 3 while ensuring the supporting force, and reduces the heat conduction. Meanwhile, as the internal clearance is large, once the ceramic pipe layer 3 is damaged, part of electrolyte can be gathered locally, the damaged part of the ceramic pipe layer 3 can be judged through different sounds generated by knocking the pipeline, the damage of the ceramic pipe layer 3 can be found at the first time, the damage of the first lead layer 7, the steel outer wall layer 6 and the second lead layer 5 can be avoided, and the service life of the external pipeline can be ensured in the long-term use process.

The asbestos tile 401 is provided with a support mechanism 403 at the joint for maintaining the gap of the asbestos tile 401 at the joint, so that the asbestos tile 401 clings to the second lead layer 5, and simultaneously, the extending space of the asbestos tile 401 is reduced to avoid the expansion and collapse caused by the extrusion of the porcelain layer 3.

A strip-shaped supporting block 402 is arranged in a gap at one side of the asbestos tile 401 close to the second lead layer 5 and close to two sides of the supporting mechanism 403. The strip-shaped supporting block 402 is matched with the supporting mechanism 403, so that the asbestos tiles 401 are prevented from being extruded and damaged by the supporting mechanism 403, and the supporting stability is further improved.

Example 2

The supporting mechanism 403 includes a first supporting portion 404 and a second supporting portion 405, an adjusting screw 406 is movably connected to the second supporting portion 405, and the adjusting screw 406 is in threaded connection with the first supporting portion 404. The gap between the first support part 404 and the second support part 405 can be controlled by adjusting the adjusting screw 406, so that the adaptability to different pipelines is improved, and the surface supporting force of the asbestos tile 401 can be actively controlled.
