The utility model provides a constant-temperature zinc launder for complex purification device to remove the zinc residue in the hot-dip galvanizing liquid, achieves continuous purification of liquid zinc, and avoids the interference of the hot dip zinc galvanizing operations of the steel plates in the purification process caused by temperature drop.
Description
Technical field
The utility model relates to the hot-galvanizing equipment field, particularly a kind of zinc liquid constant temperature chute that is used for zinc liquid purification process technique.
Background technology
Pot galvanize is to use general and the most effective technological measure in the steel anti-corrosion method up to now.The hot-dip galvanizing sheet steel of modernization continuous hot galvanizing explained hereafter is widely used in light industry, household electrical appliances, building and automobile industry.Heat zinc coating plate is except the requirement of aspects such as solidity to corrosion, intensity, deep drawing quality, and is also more and more higher to the requirement of surface quality, and coating cadmia defective is one of main mass defect of heat zinc coating plate.
In the steel plate hot galvanizing process because the dissolvings of etch, belt steel surface iron powder and the base steel of the oxidation of the reaction of solvent, air, zinc pot etc. all can make a considerable amount of iron enter in the zinc liquid, and with zinc and zinc liquid in elements such as the aluminium generation cadmia that reacts.Cadmia is different according to composition, structure, density and size, can be different states such as end slag, face slag and scum silica frost in zinc liquid.The formation of cadmia not only consumes a large amount of zinc, in case deposit or stick in the surface quality that can have a strong impact on heat zinc coating plate on sinking roller or the steel plate, therefore avoids the cadmia defective very crucial for the production of high quality heat zinc coating plate.At present, mainly take the way of " preventing " at cadmia, replace irony zinc pot etc. as processing parameters such as strictness control zinc bath temperature and immersion plating time, employing induction heating or internal heating pottery zinc pot, purpose is to suppress dissolving and the Fe-Zn speed of response of Fe, reduces the formation of cadmia from the source.In case and after cadmia formed, modal measure was to fish for the face slag by craft or mechanism from zinc liquid surface.It is not only powerless to hazardness big end slag and scum silica frost to drag for slag, also unavoidably is entrained with a large amount of pure zinc with cadmia, causes the huge waste of these narrow resources of zinc.
The Chinese invention patent application number is that 200710044702.X discloses a kind of composite purification device of removing cadmia in the hot galvanizing liquid, this device comprises zinc liquid e Foerderanlage, grade one filter and two-stage electromagnetic deslagging device, and wherein zinc liquid e Foerderanlage comprises zinc liquid pump and zinc spout.Under the effect of zinc liquid pump, constantly extract zinc liquid in the zinc pot during use to purifying in the chute, the one-level of flowing through respectively ceramic foam filter and two-stage electromagnetic deslagging device, thus reach the purpose of continuous removal cadmia.But do not provide temperature compensation in the purification chute of this device, zinc liquid is flowed through and unavoidably in the process that purifies chute is produced temperature loss, and the temperature drop that brings thus causes interference to steel plate pot galvanize operation.
Summary of the invention
The purpose of this utility model is to provide a kind of constant temperature zinc spout, when realizing that zinc liquid continues to purify, avoids purification process to cause temperature drop to disturb to steel plate pot galvanize operation as far as possible.
For achieving the above object, the technical solution of the utility model is,
A kind of constant temperature zinc spout comprises that heater case, the bottom surface of heater case and surroundings wall all are refractory materials masonries, makes shell in its outside with steel plate, arranges resistance wire within it around portion's cavity inner wall; The zinc spout is shelved in the heater case, and it is provided with bell; Thermopair is arranged in the heater case.
Again, described heater case cavity bottom is established the refractory brick supporting.
Described zinc spout adopts stainless steel to be welded.
In addition, if handle high aluminum zinc liquid, described zinc spout adopts high alumina ceramic or graphite inner bag prefabricated component.
Track is established at described heater case top, and bell can move folding along track.
The beneficial effects of the utility model
But the utility model provides a kind of homothermic zinc spout for the composite purification device of removing cadmia in the hot galvanizing liquid, when realizing that zinc liquid continues to purify, avoids purification process to cause temperature drop to disturb to steel plate pot galvanize operation as far as possible.

Fig. 2 is the cross-sectional structure synoptic diagram of the utility model zinc liquid constant temperature chute.
Embodiment
Referring to Fig. 1, Fig. 2, constant temperature zinc spout of the present utility model comprises, heater case 1, zinc spout 2;
Heater case 1, the bottom surface of heater case 1 and surroundings wall all are refractory materials masonries 4, make shell 5 in its outside with steel plate, arrange resistance wire 6 within it around portion's cavity inner wall; The heater case cavity bottom is established refractory brick 3 supportings; Thermopair 9 is arranged in the heater case 1; Be used for the transmission of temperature measuring and signal,, realize constant temperature by peripheral hardware control heating power;
Zinc spout 2 is shelved in the heater case 1, and it is provided with bell 7; Zinc spout 2 adopts stainless steel to be welded; Track 8 is established at described heater case 1 top, and bell 7 can move folding along track 8.
Zinc spout 2 adopts high alumina ceramic or graphite inner bag prefabricated component.
When work, earlier with 2 preheatings of zinc spout and constant temperature at design temperature after 15 minutes, adopt continuous type zinc liquid pump that zinc liquid is extracted out from the zinc pot, make zinc liquid flow into the zinc spout, and grade one filter and the two-stage electromagnetic deslagging device placed by portion within it purify, after the zinc liquid pump cut out when quitting work, the zinc spout continued constant temperature 15 minutes, so that the cleaning chute.
In sum, constant temperature zinc spout of the present utility model is assisted as the important of zinc liquid refining plant, provides buffer protection after zinc liquid treating plant brings into operation or cuts out, and provides temperature compensation to zinc liquid scavenging process.When realizing that zinc liquid continues to purify, avoid purification process to cause temperature drop to disturb as far as possible to steel plate pot galvanize operation.
