The utility model provides a developing and fixing film developing
barrel capable of adjusting temperature for
ray nondestructive testing, which belongs to the technical field of
nondestructive testing and comprises an outer shell, an inner shell, a
silicon rubber heating sheet, a temperature controller and a limiting groove group, the inner shell is embedded into the outer shell, and a first partition plate and a second partition plate are arranged in the inner shell, so that a developing cavity, a cleaning cavity and a fixing cavity are formed in the inner shell; the
silicone rubber heating sheets are adhered to the two sides of the outer wall of the inner shell and are respectively opposite to the developing cavity and the fixing cavity; the temperature controller is arranged on one side of the shell and connected with the
silicon rubber heating piece through a wire. According to the film developing
barrel, the three independent areas of the developing cavity, the cleaning cavity and the fixing cavity are arranged, so that cross
contamination among different processes is reduced, the temperature of the developing cavity and the temperature of the fixing cavity are accurately adjusted, the purpose that films are subjected to developing and fixing operation at the stable temperature is achieved, and then the film quality is improved.
