Technical field

The utility model relates to graphitizing furnace technical field, particularly relates to a kind of graphitizing furnace conductive electrode refrigerating unit.

Background technology

Acheson furnace is made up of the burner masonry of same structure and stove tail masonry and rectangle shaft between the two.Burner and stove tail masonry are all that refractory brick is built in outside, and charcoal block is built in upper and lower part, inner side, and graphite block is built at middle part, and several conductive electrode (Graphite Electrodes) is through burner or stove tail masonry.During being energized, conductive electrode temperature constantly raises, and therefore will cool conductive electrode.The type of cooling of prior art is outer cold process, be outside conductive electrode above water-cooled tube is set, in the cooling of conductive electrode outside surface direct trickle.This type of cooling cooling performance is poor, also can affect conductive electrode work-ing life.Water coolant cannot reclaim, around body of heater, form sewage, both causes the wasting of resources, affects Working environment again.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of good cooling results, can improve the graphitizing furnace conductive electrode refrigerating unit that conductive electrode work-ing life and water coolant can recycle.

The technical solution adopted in the utility model is: a kind of graphitizing furnace conductive electrode refrigerating unit, comprise conductive electrode group, water supply line, water inlet pipe, rising pipe and drainage pipeline, in the conductive electrode of described conductive electrode group, cooling chamber is set, described cooling chamber outer setting end cover, described end cover connects described water inlet pipe and rising pipe, described water supply line connects the water inlet pipe of the chopped-off head conductive electrode of described conductive electrode group, the water inlet pipe of the rising pipe connection second stage conductive electrode of chopped-off head conductive electrode makes to form parallel connection successively between conductive electrode described in every two-stage, the rising pipe of final stage conductive electrode connects described drainage pipeline.

Further, described conductive electrode group is 3 groups, and often organizing described conductive electrode is 3; Described water inlet pipe is deep into bottom conductive electrode cooling chamber from described end cover, and apart from described cooling chamber bottom surface 8mm ~ 12mm, described rising pipe stretches out described end cover 3mm ~ 5mm; Described drainage pipeline connects cooling water recovery device, and the water coolant in described cooling water recovery device enters hot duct by pressurization.

The utility model employing beneficial effect is: owing to arranging cooling chamber in conductive electrode inside, water coolant enters conductive electrode inside and cools, adopt end cover to seal, effectively can reduce temperature, improve the reliability of conductive electrode work and increase the service life.Water inlet pipe is deep into bottom cooling chamber, water shoot is substantially concordant with end cover inner face, can make fully cooling water circulation, improve cooling performance further.Water pipe between the conductive electrode of conductive electrode group is connected in series, and makes water-cooled tube compact in design, saves space.Water coolant is undertaken reclaiming by retrieving arrangement and pressurizes and enter hot duct and can utilize resource further, also eliminate water coolant simultaneously and run and emit leakage problem, improve Working environment.
