Method for producing board layers of freeze dryers by utilizing aluminum alloy sections

Abstract

The invention relates to a method for producing board layers of freeze dryers by utilizing aluminum alloy sections. The method is characterized by comprising the following steps of (1) rolling the aluminum alloy sections; (2) cutting the aluminum alloy sections; (3) machining cutting faces; (4) sealing cutting faces at two ends; (5) machining liquid inlet tubes and liquid outlet tubes on sealing faces (or two sides of the sections). The method has the remarkable advantages that an aluminum alloy material is high in plasticity and can be machined into sections in any shape, the rigidity of the aluminum alloy material is higher than that of stainless steel, the thermal conductivity of the aluminum alloy is excellent and is twice the thermal conductivity of stainless steel, and cold and heat carried by silicone oil in the board layers can be released maximally through the excellent thermal conductivity of the aluminum alloy, so the temperature uniformity of the board layers is greatly improved.

Problems solved by technology

In addition, there are too many places that need to be welded, which makes the thermal deformation of the board layer too large, which adds a lot of difficulty to the shaping. If the shaping is not good, it will directly affect the quality of the planer. It will cause a lot of trouble for water mills, abrasive belts, etc. Due to the weaknesses of stainless steel itself, such as its large specific weight (7.93kg / m3), poor rigidity, etc., the heavy weight of the board when it is hoisted causes the middle of the board to collapse, directly Affect the flatness of the surface of the board layer, making it difficult to meet the ideal technical design requirements

The traditional ply manufacturing process is basically processed by manual welding and splicing, which is labor-intensive, low-efficiency, difficult to guarantee the shape and size, and cannot form standardized and standardized production, especially for plug welding, edge welding, liquid inlet and outlet pipes, and manifolds. The hidden danger of leakage caused by welding has always been a heart disease for freeze dryer manufacturers and pharmaceutical manufacturers
