Technical Field

The invention belongs to the technical field of stirring equipment, and relates to a helical ribbon type stirring paddle.

Background

High efficiency of the paddles has been a goal sought by the stirring industry. The stirring paddle is an important part of stirring equipment, and the stirring efficiency can be greatly improved by one good stirring paddle, the reaction time is shortened, the yield of finished products is improved, the product quality is improved, and the like.

Disclosure of Invention

The invention aims at the problems and provides a helical ribbon type stirring paddle which is suitable for high-efficiency stirring in the processes of mixing, heat transfer, reaction and the like of medium and high viscosity liquid.

According to the technical scheme of the invention: the utility model provides a helical ribbon stirring rake which characterized in that: including the (mixing) shaft, the circumferential surface interval of (mixing) shaft has the support horizontal pole that mutually perpendicular set up, a main spiral shell area blade is drawn forth respectively at the both ends that (mixing) shaft upper portion supported the horizontal pole, main spiral shell area blade from last down in proper order with each end connection who supports the horizontal pole, the lower extreme of two main spiral shell area blades extends to the lower extreme of (mixing) shaft respectively, bottom spiral shell area blade is connected to main spiral shell area blade bottom surface.

As a further improvement of the invention, the surface of the stirring shaft is provided with connecting pipes which are perpendicular to each other at intervals, the outer end of each connecting pipe is provided with a connecting flange, and the supporting cross rods are fixedly connected with the connecting flanges.

As a further improvement of the invention, the upper end part of the stirring shaft is fixedly provided with a shaft flange.

As a further improvement of the invention, the main helical ribbon blade is of a detachable structure.

As a further improvement of the invention, two main helical blades are symmetrically arranged around the stirring shaft.

As a further improvement of the invention, the outer spiral line of the bottom helical ribbon blade spirally rises according to the elliptic curved surface of the end socket.

The invention has the technical effects that: (1) the main helical ribbon blade of the stirrer is detachable, the upper end socket of the stirring tank and the barrel can be directly welded without adopting a large flange, and the stirring paddle can enter the reaction kettle through a manhole for installation, so that the manufacturing cost of the reaction kettle is reduced, and meanwhile, the sealing property of the tank body is improved.

(2) The support cross rods of the stirrer are connected by adopting sectional flanges, so that the installation is simplified, holes or key grooves do not need to be drilled on the shaft, and the strength of the stirring shaft is not reduced.

(3) The bottom paddle blade of the stirrer is an elliptical spiral curved surface, and forms a complete axial flow with the main helical ribbon blade during working, so that bottom materials are promoted to participate in the large circulation of the whole fluid, the mixing effect of the centering and high-viscosity fluid is better than that of a bottom anchor (frame) type paddle, and the poor mixing area at the bottom of the elliptical tank can be effectively eliminated.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

In fig. 1 ~ 4, the mixer includes a shaft flange 1, a mixing shaft 2, a support cross bar 3, a connecting flange 4, a main ribbon blade 5, a bottom ribbon blade 6, and the like.

As shown in fig. 1 ~ 4, the present invention is a ribbon stirring paddle, including a stirring shaft 2, wherein support cross rods 3 are arranged on the circumferential surface of the stirring shaft 2 at intervals and are perpendicular to each other, two ends of the support cross rod 3 on the upper portion of the stirring shaft 2 are respectively led out a main ribbon blade 5, the main ribbon blades 5 are sequentially connected with the end portions of the support cross rods 3 from top to bottom, the lower ends of the two main ribbon blades 5 respectively extend to the lower end of the stirring shaft 2, and the bottom surface of the main ribbon blade 5 is connected with a bottom ribbon blade 6.

The surface interval of (mixing) shaft 2 is provided with mutually perpendicular's connecting pipe, every the outer end of connecting pipe all sets up flange 4, supports horizontal pole 3 and flange 4 fastening connection.

The fixed axle flange 1 that sets up of upper end of (mixing) shaft 2, at the during operation, (mixing) shaft 2 is connected with external drive shaft through axle flange 1.

The main helical ribbon blade 5 is of a detachable structure, so that the production and the manufacture of the main helical ribbon blade 5 are greatly facilitated, namely, each section of blade can be produced in a segmented mode, and then each section of blade is fastened and connected through a bolt to form the complete main helical ribbon blade 5.

The two main helical blades 5 are symmetrically arranged around the stirring shaft 2, so that the main helical blades 5 can realize a uniform stirring effect when working; the outer spiral line of the bottom helical band blade 6 spirally rises according to the elliptic curved surface of the seal head.
