Abstract
The utility model discloses a strontium nitrate discharge cooling pipe which comprises a product conveying pipe located between a drying box and a grinder, wherein a cooling pipe is arranged on the surface of the product conveying pipe, and an inlet and an outlet of a cooling liquid are formed in two ends of the cooling pipe respectively. Compared with a traditional cooling method, the cooling pipe is arranged on the surface of the product conveying pipe, so that the strontium nitrate cooling time is shortened, the cooling effect of strontium nitrate becomes better, and the production efficiency is improved; and because the cooling effect of strontium nitrate becomes better, the heat damage ratio of the grinder is reduced, and the maintenance cost of equipment is reduced.
Description
Technical field
The utility model relates to a kind of refrigerating unit, especially relates to a kind of refrigerating unit of producing strontium nitrate.
Background technology
Strontium nitrate is a kind of important inorganic product that becomes more meticulous, take industrial nitric acid and industrial magnesium strontium as raw material, make the strontium nitrate product through reaction, removal of impurities, concentrated, crystallization, centrifugal, drying and packing successively, the drying process of described strontium nitrate is: with strontium nitrate put into 120～140 ℃ of temperature, vacuum tightness-0.06～-vacuum drying oven of 0.08MPA, be dried to the final water content of product≤0.1%; Then dried strontium nitrate is taken out, through the cooling tube cooling, the temperature of strontium nitrate is cooled to identical with envrionment temperature.
In existing strontium nitrate manufacturing processed, strontium nitrate is because the rear extreme temperatures of oven dry in crushing process, causes the damage of shredding unit easily.Common practices is to install a cooling tank additional at present, and logical cold wind after the strontium nitrate temperature reduces by the time, is pulverized, packed.Such method of cooling cooling performance is bad, causes shredding unit fragile because of strontium nitrate temperature height; Cooling time is longer, and production efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of strontium nitrate refrigerating unit.Reduce cooling time in the strontium nitrate process of producing product, enhance productivity; It is fragile to avoid pulverizer to be heated, and reduces cost of equipment maintenance.
The utility model is achieved through the following technical solutions: comprise the product feeding tube between drying baker and pulverizer, described product feeding tube surface is provided with cooling tube, and the cooling tube two ends are respectively equipped with the import and export of cooling fluid.
The beneficial effects of the utility model are: compare with traditional method of cooling, be provided with cooling tube on described product feeding tube surface, shortened like this strontium nitrate cooling time and so that the strontium nitrate cooling performance improved so that production efficiency improves; Because the strontium nitrate cooling performance improves, reduced like this pulverizer because of the heat damage rate, thereby reduced the maintenance cost of equipment.
Further, described cooling tube is made as spirrillum, has increased like this heat exchange area of cooling tube, improved the cooling efficiency of described strontium nitrate refrigerating unit, reduced cooling time.
Description of drawings
Fig. 1 is a kind of strontium nitrate discharging of the utility model pipe structure for cooling synoptic diagram.
Embodiment
By reference to the accompanying drawings 1, the utility model discloses a kind of strontium nitrate discharging cooling tube, comprise the product feeding tube 2 between drying baker 1 and pulverizer 3, described product feeding tube 2 surfaces are provided with cooling tube 4, and cooling tube 4 two ends are respectively equipped with the import and export of cooling fluid.
Strontium nitrate is after drying baker 1 hyperthermia drying, extreme temperatures, before being transported to pulverizer 3, the processing of lowering the temperature, so the utility model is provided with cooling tube 4 on described product feeding tube 2 surfaces, and because cooling tube is set to spirrillum, cooling tube 4 heat exchange areas have been strengthened, cooling fluid can fully be carried out heat exchange with product like this, for so that heat exchange effect becomes is better, the product throughput direction is opposite with coolant flow direction, so cooling fluid is from carrying inlet end to enter away from product, carrying inlet end to flow out near product.Product is sent into pulverizer 3 and is pulverized through after fully cooling off, and processes by pack at pulverizer 3 exit end at last.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. a strontium nitrate discharging cooling tube comprises the product feeding tube between drying baker and pulverizer, it is characterized in that: described product feeding tube surface is provided with cooling tube, and the cooling tube two ends are respectively equipped with the import and export of cooling fluid.
2. a kind of strontium nitrate discharging cooling tube according to claim 1, it is characterized in that: described cooling tube is spirrillum.
