A steam hydrolysis pot is sealed with water

Abstract

The invention relates to a water sealing cover for a steam hydrolysis pot, which includes a pot body, a water sealing ring and a water sealing cover; a matching groove is opened on the edge of the water sealing ring, and a rubber ring is symmetrically arranged at the inner bottom of the matching groove. The cross-section of the rubber ring is a right triangle, the bottom end of the water seal cover is embedded between the two rubber rings, and the water seal cover closely fits the slope of the rubber ring; the matching groove and The water injection mechanism is connected to each other, and the water injection mechanism includes a U-shaped pipe and an adjustment mechanism; one end of the U-shaped pipe is connected to the matching groove, and the other end of the U-shaped pipe is connected to the water tank, and the adjustment mechanism is used to adjust The drainage of the water tank is on and off; the steam hydrolysis pot is sealed with water to realize automatic water addition and ensure the hydrolysis effect of titanium dioxide.

Description

technical field [0001] The invention relates to a water sealing cover for a steam hydrolysis pot, which belongs to the technical field of titanium dioxide production. Background technique [0002] Titanium dioxide is widely used in various structural surface coatings, paper coatings and fillers, plastics and elastomers. Other uses include ceramics, glass, catalysts, coated fabrics, printing inks, roof granules and fluxes; in the production of titanium dioxide In the process, it is necessary to use a hydrolysis pot to hydrolyze the titanium white solution. During the hydrolysis process, high-temperature gas will be continuously filled into the hydrolysis pot to heat the titanium white solution to above 100°C for hydrolysis. [0003] The top of the hydrolysis pot is provided with a water sealing cover to seal the pot body, and water is used to fill the gap in the water sealing cover to achieve the effect of heat preservation and pressure maintaining; however, due to the high t...

Problems solved by technology

[0003] The top of the hydrolysis pot is provided with a water sealing cover to seal the pot body, and water is used to fill the gap in the water sealing cover to achieve the effect of heat preservation and pressure maintaining; however, due to the high temperature of the pot body, the water sealing cover The water is evaporated, resulting in a decrease in the water volume in the water seal cover. If the water volume drops to a certain position, the water seal effect will be lost. Therefore, workers need to check the water volume in the water seal cover frequently, and send water to the water seal through the external water pipe in time. Adding water in the cover, adding water through the water pipe is relatively cumbersome, and the amount of water added is not easy to control, and once the workers forget to add water, it is easy to cause the air pressure and temperature in the hydrolysis pot to drop, which will affect the hydrolysis effect of titanium dioxide
