Embodiment 1

[0025] See Figure 1-4 , A stirring reaction device for the production of carboxymethyl cellulose nitrate, comprising a tank body 11, the tank body 11 is installed with a shaking and rotating frame 9, the shaking and rotating frame 9 can realize the rotation and shaking during the working process, and the stirring is uniform. Conducive to reaction.

[0026] Further, the rocking rotation frame 9 is provided with a rotating shaft 18, a stirring rod 17 is installed on the rotating shaft 18, a limit sleeve 19 is sleeved at the center of the rotating shaft 18, and the limit sleeve 19 is externally fixed with a limit tube 20, The outer periphery of the position tube 20 is convex. The limit tube 20 is fixed to the fixed frame 10 by a spherical hinge. The fixed frame 10 is provided with a fixed tube. The inside of the fixed tube matches the limit tube 20 with a spherical cavity, and the fixed tube is connected through The tube is fixed inside the tank 11, the upper end of the rotating sh...

Embodiment 2

[0029] See Figure 1-5 , A stirring reaction device for producing carboxymethyl cellulose nitrate, which is added on the basis of embodiment 1: a fixing plate 131 is installed on the supporting leg 13, an inner support rod 132 is fixed at the lower end of the fixing plate 131, and the inner support The lower end of the rod 132 is inserted into the outer sleeve 134, the inner support rod 132 is sleeved with a spring 133, the upper end of the spring 133 is fixed on the fixing plate 131, and the lower end of the spring 133 is fixed on the outer sleeve 134.

Abstract

The invention discloses a stirring reaction device for producing carboxymethyl cellulose nitrate. The stirring reaction device comprises a tank body, and the tank body is provided with a shaking self-rotating frame. A motor is started to drive a turntable to rotate, the turntable drives the shaking self-rotating frame to revolve, and the shaking self-rotating frame is limited in a fixed frame through a limiting tube so that the shaking and revolving are realized. In revolving of the shaking self-rotating frame, the shaking self-rotating frame self-rotates through a gear and a ring-shaped rackmeshed with the gear so that the stirring is full and uniform and the reaction is promoted.

Description

Technical field [0001] The invention relates to a stirring reaction device, in particular to a stirring reaction device for producing carboxymethyl cellulose nitrate. Background technique [0002] Natural cellulose is the most widely distributed and most abundant polysaccharide in nature, and its source is very rich. The current modification technologies of cellulose mainly focus on etherification and esterification. Carboxymethylation reaction is a kind of etherification technology. After carboxymethylation of cellulose, carboxymethyl cellulose (CMC) is obtained. Its aqueous solution has the functions of thickening, filming, bonding, water retention, colloid protection, emulsification and suspension, etc., and is widely used in petroleum, food, and medicine. , Textile and papermaking industries are one of the most important cellulose ethers. [0003] The stirring reaction device used to produce carboxymethyl cellulose nitrate, which is the base material of green water-based pai...
