Description

Technical Field

[0001] The utility model relates to the technical field of sublimator equipment, in particular to a special sublimator for large-scale production. Background Art

[0002] Sublimators are mainly used to purify substances. Traditional sublimators are generally made of glass and are processed in trace amounts. Glass sublimators are fragile and cannot meet the requirements of large-scale industrial production (such as kilograms).

[0003] In the prior art, the sublimator structure design adopts a method of directly connecting the middle tank body and the bottom bin, but the diameter of the hollow structure on the inner side of the upper disk of the bottom bin is smaller than the diameter of the hollow structure of the bottom bin, so that the inner wall of the bottom bin is not a plane in the vertical direction, but is actually a structure with a circle of protrusions; when the sublimator is placed on a heating device and cooling water is introduced, the temperature at the connection position of the middle tank body and the bottom bin drops significantly under the cooling effect of the cooling water and the good thermal conductivity of the steel. At this time, most of the gaseous substances in the sublimator are cooled at this position to form solid final products and are accumulated on the upper side wall of the bottom bin; due to the protrusion of the upper disk of the bottom bin, the products on the side wall of the bottom bin cannot be observed and cannot be completely scraped out, resulting in a decrease in the yield and sublimation efficiency of the sublimation reaction.

[0004] Therefore, when using stainless steel sublimators for production, the high thermal conductivity of stainless steel leads to problems such as difficulty in manual collection of the final product, low product yield and sublimation efficiency. In addition, because stainless steel is an opaque material, the sublimation process cannot be observed in real time. Utility Model Content

[0032] See also Figures 1 to 3 As shown, the utility model is a sublimator specially used for large-scale production, comprising a top cover 1, a middle tank body 2, an extended tank body 3 and a bottom bin 4 arranged in layers from top to bottom, the top cover 1 and the middle tank body 2 are detachably connected, the middle tank body 2 and the extended tank body 3 are connected in an integral structure, and the extended tank body 3 and the bottom bin 4 are detachably connected; wherein, a cooling structure for condensing and attaching the sublimation material is provided on the middle tank body 2.

[0033] During the production and use of the sublimator dedicated to large-scale production of the present application, the material is evenly spread in the bottom grid of the bottom bin 4, and after the top cover 1, the middle tank body 2, the extended tank body 3 and the bottom bin 4 arranged in layers from top to bottom are fixed and tightly connected, the bottom bin 4 is buried in the aluminum sand heating medium for heating, and the middle tank body 2 is cooled by a cooling structure; after the sublimator is heated to a certain temperature, the solid material in the bottom grid of the bottom bin 4 begins to sublime, and under the cooling effect of the cooling structure, most of the sublimated gas will be deposited in the extended tank body 3 and the middle tank body 2; after the sublimation process is completed, the heating is stopped and the cooling structure is closed, and the final product deposited in the extended tank body 3 and the middle tank body 2 can be scraped off.
