Abstract

The invention discloses a concentration evaporator for sodium sulfide. The concentration evaporator comprises a heating chamber and a heat exchange cylinder. A discharging port is formed in the side wall of the heat exchange cylinder, a stirring mechanism is arranged in the heat exchange cylinder and comprises a rotating shaft, a sleeve, a support and a spiral band, the rotating shaft and the heat exchange cylinder are coaxial, the sleeve sleeves the rotating shaft and is in running fit with the rotating shaft, the support is fixedly connected with the sleeve, the spiral band is arranged on the support, a clamp groove is formed in one end of the sleeve, a fixing pin matched with the clamp groove is arranged on the rotating shaft, a push plate is arranged at the other end of the sleeve, a spring for keeping the sleeve contacting with the fixing pin is arranged on the rotating shaft, a cover plate is arranged at the discharging port, a lever is hinged onto the inner wall of the heat exchange cylinder, one end of the lever is hinged to the cover plate, the other end of the lever is abutted to the push plate, and a second driving mechanism for driving the rotating shaft to rotate is arranged on the heating chamber. The concentration evaporator solves the problem of inconvenience in discharging operation of a heat exchange cylinder in the prior art, and automatic discharging is realized.

Description

technical field [0001] The present invention relates to an evaporator for alkali sulfide. Background technique [0002] In the production process of soda sulfide, it is necessary to use an evaporator to evaporate and concentrate the soda sulfide solution to obtain a higher concentration of soda sulfide solution, which is convenient for subsequent tablet production operations. The publication number is CN101507882 B, and the patent name is evaporator, which discloses a heating chamber and a heat exchanger installed in the heating chamber. The heating chamber has a high-temperature gas inlet and a gas outlet, and a heat exchange cylinder is installed in the heating chamber. Both ends have hollow shafts communicating with the inside of the heat exchange cylinder respectively. The two hollow shafts are coaxial. There is an openable and closed discharge port on the wall of the heat exchange cylinder. A driving device is installed outside the heating chamber. The heat exchange cy...
