Sealed mixing tank wall washing device

Abstract

The invention provides a sealed mixing tank wall washing device, comprising a mixing system, a nozzle system and a ventilation system, wherein the mixing system is connected with the nozzle system, and the mixing system is connected with the ventilation system. According to the present invention, a lower end of a shaft is provided with a through hole, materials just below the shaft is pumped by a pump mounted on the bottom of the shaft and is sprayed to a tank wall through a nozzle on the top, solids coagulated on the tank wall is rinsed off, the tank wall is kept clean and the mixing effect of the materials is improved. The nozzle of the device is a direct flow nozzle which sprays liquid linearly, and is rotated with the shaft to rinse off the tank wall in all directions, thus the problem of some dead angles cannot be sprayed is prevented. The ventilation system is used for generating positive pressure, negative pressure and drying steam, and exhausting toxic gases for the apparatus.

Description

technical field [0001] The invention relates to a stirring device, in particular to a sealing device for extracting stirring liquid to wash the barrel wall during stirring. Background technique [0002] Stirring is a production technology mastered earlier by human beings. It can disperse two or more different substances among each other, so as to achieve uniform mixing; it can also accelerate the process of heat transfer and mass transfer. In industrial production, stirring operation started from the chemical industry, and is widely used as a part of the process around food, fiber, papermaking, water treatment, etc., and its main purpose is to accelerate the mass transfer or heat transfer process in the system. Stirring technology has also been developed and applied in the production of the petroleum industry, especially in the design and application of some large storage tanks, which can make the storage liquid in the storage tank evenly mixed and uniform in temperature, pr...

AI Technical Summary

Problems solved by technology

[0014] In order to solve the deficiencies of the existing technology and solve the problem that the solid material bonded on the barrel wall and the area directly under the stirring blade cannot be stirred, a method of extracting the stirring liquid from directly below the stirring blade is designed, and the barrel wall is washed back and forth through the nozzle, and at the same time, it can Provide negative pressure sealed mixing tank wall flushing device
