Problems solved by technology

[0002] Plaster mold is an auxiliary tool widely used in plastic molding in the daily ceramic industry. When making plaster molds, gypsum and water are generally put into the mixing drum according to a certain ratio, and a single motor is used to drive the stirring paddle to stir in the mixing drum to achieve To achieve uniformity, because there are a lot of air bubbles in the gypsum slurry, pinholes appear when the gypsum mold is formed, and the density is low, which seriously affects the mechanical strength and performance of the gypsum mold. The service life of the gypsum mold is low, and the water absorption rate is not equal. The green body made is easy to dry and crack, and the yield decreases
[0003] Because the gypsum will coagulate in a short period of time after adding water to make a slurry, people have made a lot of improvements in continuous exploration, especially the emergence of vacuum mixers, which are suitable for the special needs of gypsum mixing, but the traditional vacuum mixers are still Using a single motor and a single mixing drum to work, workers have to manually operate the stirring shaft up and down when operating the mixer, which is labor-intensive and low in production efficiency.

Abstract

The invention discloses a vacuum stirrer and belongs to the technical field of domestic ceramic mechanical equipment. The vacuum stirrer comprises a machine base, an n-shaped bracket, a lower bell jar, an upper bell jar, a coiling wheel, a coiling wheel motor and an air pipe, wherein the n-shaped bracket and the lower bell jar are fixedly mounted on the machine base; sliding guide slots are formed in the inner sides of two stand columns of the n-shaped bracket; the coiling wheel is electrically connected with the coiling wheel motor and is arranged on the n-shaped bracket; the upper bell jar and the lower bell jar are covered by sealing adhesive tapes; a stirring motor is mounted inside the upper bell jar; guide wheels capable of moving up and down along the sliding guide slots are respectively arranged on the left side and the right side of the outer side of the upper bell jar; a pulley is also arranged at the top of the upper bell jar and is connected with the coiling wheel by virtue of a steel wire rope; the air pipe runs through the machine base and the lower bell jar and extends into the upper bell jar; the lower end of the air pipe is arranged under the machine base and is connected with a vacuum valve and an air valve by virtue of a three-way pipe. The vacuum stirrer is capable of stirring gypsum under the vacuum condition, fully removing bubbles in the process of stirring the gypsum and ensuring that the gypsum is uniformly stirred.
