Description
Technical field
The present invention relates to a kind of refrigerating unit, be specifically related to a kind of hermetic seal water-chilling plant that utilizes abundant gas and liquid.
Background technology
In the pellet sintering process, need the pelletizing that sintering comes out be cooled off, the widespread usage cooler cools off it at present.Traditional cooler is to adopt ventilation refrigerative mode, and there are many shortcomings in this cold-zone mode; At first, when the pelletizing iron-holder surpasses 80%, airborne oxygen very easily with agglomerates of sintered pellets generation oxygenizement, cause material loss serious, formed huge waste.The second, because the specific heat capacity of wind is little, thus need the air quantity of cooling air very big, so the power height of blower fan, energy consumption is very big; The 3rd, in order to reach cooling performance, the length of equipment is generally all very long, causes overall dimension, tonnage, the cost of equipment all very high.The 4th, the dust in the material is kicked up, and also needs a cover dust collection system.
Summary of the invention
At above-mentioned technical problem, the purpose of this invention is to provide a kind of good cooling results, and can avoid workpiece under high temperature action, to contact oxidized hermetic seal water-chilling plant with oxygen, the present invention has simple in structure, the advantage that floor space is little.
The technical scheme that realizes above-mentioned purpose is as follows:
The hermetic seal water-chilling plant, comprise cooling cylinder, in described cooling cylinder comprises revolving drum and with this in the outer cooling cylinder of revolving drum running fit, revolving drum is connected with outer cooling cylinder by bearing in described, the two ends of interior revolving drum extend to the outside, end of outer cooling cylinder respectively, the two ends of interior revolving drum are connected with a supporting device separately, the feed end of interior revolving drum connects a feeding unit, between the feed end of feeding unit and interior revolving drum, be provided with the gas sealing mechanism that blocks air, the discharge end of interior revolving drum and one drives its rotating drive unit and is connected, and comprises that also an external cooling cylinder provides the refrigerative water cooler.
Adopted such scheme, nitrogen by the gas sealing mechanism ejection, in the endoporus of gas sealing mechanism, form a gas disc, this gas disc becomes a gas curtain that can stop air admission to arrive interior revolving drum, thereby it is air is isolated, exempt to make workpiece to be subjected to airborne dioxygen oxidation, like this by having formed the hermetic seal effect in the internal revolving drum of gas.And in the nitrogen of gas sealing mechanism ejection enters into after the revolving drum, because the effect of nitrogen can be isolated the little air that workpiece is brought into from the outside, thereby, further stoped the oxygenizement of workpiece.Because interior revolving drum is delivered to heat on the outer cooling cylinder by heat passage meeting, in time siphon away by heat passage by the heat on the revolving drum in the outer cooling cylinder chief commander, and provide cooling source that heat is taken away by the water cooler that is arranged on this outer cooling cylinder, and the decoration form of the water-cooled tube of water cooler is the spiral canoe, therefore, the surface of whole substantially outer cooling cylinder has all obtained the thermolysis of water coolant, therefore, has the advantage of good heat dissipation effect.In addition,, can shorten the length of cooling cylinder, help reducing the floor space of whole device, and the present invention only is made up of the component of minority, has advantage of simple structure by radiating mode of the present invention.
The invention will be further described below in conjunction with the drawings and specific embodiments.
