Thermostatic impregnation device used for laboratory

Abstract

The invention discloses a thermostatic impregnation device used for a laboratory. The thermostatic impregnation device comprises a thermostatic oven and a rotary drum, wherein a left rotating shaft and a right rotating shaft are respectively and fixedly arranged at two ends of the rotary drum and rotatably connected with a support; the rotary drum and the support are arranged inside the thermostatic oven; the support is connected with and fixedly arranged at the bottom part of the thermostatic oven; the right rotating shaft penetrates through the side wall of the thermostatic oven and is rotatably connected with the side wall of the thermostatic oven; the right end of the right rotating shaft is fixedly connected with the output shaft of a motor; and the motor is fixedly arranged on and connected with the side wall of the thermostatic oven. When an impregnation experiment is performed, a sealed impregnation container filled with an impregnation solution is fixedly arranged inside the rotary drum; the door of the thermostatic oven is closed; the temperature of the interior of the thermostatic oven is set; the motor is started and drives the rotary drum arranged in the thermostatic oven to rotate; thus, the impregnation solution can be experimented under the conditions of a constant temperature and continuous and uniform shaking, so experimental effects can be effectively guaranteed, and the accuracy of experimental data is improved.

Description

technical field [0001] The invention relates to a constant temperature impregnation equipment used in laboratories, and is especially suitable for the research field of preparation of supported catalysts. Background technique [0002] The impregnation method is one of the main methods for the preparation of supported catalysts. In the process of catalyst preparation research in the laboratory, due to the limitation of laboratory equipment conditions, there is a certain gap with the industrial production process. At present, catalyst impregnation in the laboratory usually involves mixing the impregnating solution and the catalyst evenly, sealing with a plastic wrap, a sealing cover, etc., leaving it at room temperature for 1-5 hours, and shaking it every 5-20 minutes to ensure uniform impregnation. Because the impregnation effect is greatly affected by temperature, some impregnation processes are carried out in a constant temperature oven. The above impregnation method has t...

AI Technical Summary

Problems solved by technology

The above impregnation method has the following disadvantages: due to the large temperature difference in summer and winter, and unstable room temperature conditions, the experimental results are greatly affected by the external impregnation environment; regular shaking, there is still uneven impregnation of the prepared catalyst; when impregnated in a constant temperature oven , cannot be shaken regularly, the impregnating liquid cannot fully contact with the catalyst; when shaken regularly in a constant temperature oven, the constant temperature condition becomes unstable due to the need to regularly open and close the oven door to shake well

These shortcomings directly affect the experimental results, and the accuracy of the experimental data is difficult to guarantee
