Problems solved by technology

Due to the limitation of this structure, the stirring effect is not uniform, and the heat exchange capacity is not enough, so that the annual output of a single tank cannot be increased.
In this way, it not only increases the investment in equipment use site, process pipeline, instrument control, etc., but also brings greater difficulty to equipment management.
At the same time, when the fluid material in the original vertical etherification tank is added to the tank, material stratification will occur in the tank, which cannot guarantee the complete homogeneous mixing of the materials in the tank

Embodiment 1

[0025] As shown in Figures 1 to 2, a horizontal etherification reaction kettle is mainly composed of a jacket 16 inside a cylinder 17 to form a kettle body 3. The cylinder 17 is connected and fixed with the bottom frame 11. 17 two ends are installed cylinder head 26, and cylinder head 26 adopts flat-bottomed head, and flat-bottomed head is used for sealing kettle body 3. A rotating agitator 5 is arranged in the center of the kettle body. The agitator shaft 5 penetrates from the right end of the kettle body 3 until it extends out from the left end. 2 and the right end shaft seal box 6 are respectively connected with the left bearing seat 1 and the right bearing seat 7, the stirring shaft is supported by the left bearing seat 1 and the right bearing seat 7, and the left bearing seat 1 and the right bearing seat 7 are respectively fixed with the base frame 11. A plurality of coulter-type agitators 4 are staggeredly installed on the stirring shaft 5, and the coulter-type agitators...

Embodiment 2

[0030] As shown in Figures 6 to 7, the structure of this embodiment is basically the same as that of Embodiment 1, except that oval-shaped heads 27 are installed at both ends of the reactor body of the reaction vessel, and the oval-shaped heads 27 are used to seal the kettle body 3 . A plurality of flying knife assemblies are arranged on the inner cylinder arm of the kettle body 3, and the flying knife assembly is composed of a flying knife base 10, a drive motor 23 and a flying knife blade 24, and the driving motor 23 and the flying knife blades are installed on the flying knife base 10. Blade 24. The flying knife assembly is used to crush and shear the agglomerated materials and long fibers, so that the materials are mixed uniformly, which is more in line with the requirements of the production process.

Abstract

The invention relates to a horizontal etherification reactor, in particular to a horizontal etherification reactor for producing cellulose by a semidry process and a dry process, which pertains to the technical field of chemical machinery, wherein, a reactor body is arranged in a cylindrical body which is connected and fixed with an under frame; a rotation mixing shaft is arranged in the center of the reactor body; the two ends of the mixing shaft are respectively sheathed on a left-end shaft sealing box and a right-end shaft sealing box; a right bearing holder is connected with a reducer by a coupler; the reducer is connected with a motor and fixed on a motor base. The horizontal etherification reactor is characterized in that a plurality of coulter-typed mixers are arranged on the mixing shaft in a staggered manner and distributed by unequal intervals along the axes of the mixing shaft and the distribution angle is 90 degrees or 120 degrees. The coulter-typed mixers consist of paddle arms and coulter-typed blades, and the coulter-typed blades are arranged on the paddle arms. The horizontal etherification reactor has uniform mixing effect and good heat exchange performance and can effectively improve the output of a single reactor and product quality while shortening the handing time of the technique.

Description

technical field [0001] The invention relates to a horizontal etherification reaction kettle, in particular to a horizontal etherification reaction kettle for producing cellulose by a semi-dry method or a dry method, and belongs to the technical field of chemical machinery. Background technique [0002] In the existing technology, most of the etherification reactors used in the production of cellulose and other industries are vertical kettles, and most of them are 5m reactors developed in the early stage. 3 Vertical etherification reactor, only a small amount of 20-30m 3 etherification reactor. Among them, 5m 3 The vertical etherification reactor is being phased out, 30m 3 Because there is no breakthrough in the technical performance of the kettle, it has not been popularized and applied for a long time. The vertical etherification kettle is mainly composed of a cylinder body, a reactor body and a jacket to form a reactor vessel body. A stirring shaft is installed in the ...
