Description

Stirred tank

Technical field

The present invention relates to a kind of stirred tank, be specifically related to a kind of stirred tank.

Background technology

In Chemical Manufacture operation, often can be uniformly mixed industrial chemicals, modal chemical products stirred tank is always with the container or the device that stir, in being usually used in Chemical Manufacture, material is uniformly mixed.Common stirred tank is generally and on single shaft, array plane blade is installed and stirs by driven by motor, inner wall of kettle is generally smooth inner wall, tend to cause near the inhomogeneous situation of the mixing of materials of inner wall of kettle and occur, because motor starting velocity is just very fast, but material compares again thickness, tend to cause shaft to rotate and be obstructed, shaft easy fracture.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of paddle fracture that prevents, mixing effect is good, the stirred tank that operating efficiency is high.

To achieve these goals, the invention provides a kind of stirred tank, comprise kettle, shaft and paddle, wherein, described kettle sidewall is welded with polylith baffle plate, described baffle plate is axial curved face type, the cross section of described baffle plate is vertical with described kettle madial wall, and described paddle is longitudinally oval, and the back side of this paddle is provided with reinforcement along its length.

Adopt the stirred tank of technique scheme to have following advantage: 1, owing to being welded with polylith baffle plate on kettle sidewall, and baffle plate is axial curved face type, in the process that the material that is arranged so that close kettle sidewall of baffle plate rotates in kettle, be again subject to the impact of baffle plate, change its directed rotation direction, thereby make it more abundant in the mixing being subject to after baffle plate impacts, the design of curved surface has simultaneously expanded baffle plate impact area, and mixed effect is further improved; 2, because paddle is longitudinally oval, oval-shaped design makes paddle in the process stirring, reduced the resistance between paddle and material, meanwhile, with traditional individual layer paddle comparison, the degree of depth stirring is deepened to some extent, mixing effect is better, and upper and lower mixing between material bed is more easily realized, has avoided mixing with layer material up and down not reach desirable admixture, therefore, mixing effect is embodied; 3, the back side due to paddle is provided with reinforcement along its length, the design of reinforcement make to be obstructed self intensity of larger paddle itself is strengthened to some extent, reduce the possibility of paddle fracture, and saved maintenance and the trouble of changing agitating device, improved operating efficiency.

As preferred version, consider the abundant effect of mixing of materials, described baffle plate is 3～8 uniform circumferential settings.

As preferred version, consider the long-term use of paddle, its intensity can be subject to certain reduction, and in order to guarantee the intensity of paddle, described reinforcement is two.

As preferred version, in order to realize the control to agitator shaft speed, described shaft is connected with the clutch end of peripheral hardware motor, and described motor is also connected with frequency converter.

the specific embodiment

Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:

As depicted in figs. 1 and 2, the invention provides a kind of stirred tank, comprise kettle 1, shaft 2 and paddle 3, wherein, kettle 1 sidewall is welded with polylith baffle plate 4, baffle plate 4 is axial curved face type, the cross section of baffle plate 4 is vertical with kettle 1 madial wall, and paddle 3 is longitudinally oval, and the back side of this paddle 3 is provided with reinforcement 31 along its length.In addition, consider the abundant effect of mixing of materials, baffle plate 4 is 3～8 uniform circumferential settings, and the present embodiment arranges five baffle plates 4; Consider the long-term use of paddle 3, its intensity can be subject to certain reduction, and in order to guarantee the intensity of paddle 3, reinforcement 31 is two; In order to realize the control to shaft 2 rotating speeds, shaft 2 is connected with the clutch end of peripheral hardware motor 5, and motor 5 is also connected with frequency converter 6.

In whipping process, longitudinal oval paddle needs, by the cooperation of frequency converter and motor, its rotating speed is carried out to suitable adjustment at the beginning of starting, its rotating speed is adjusted to lower state, when the viscosity to material decreases, again the rotating speed of paddle is heightened, and keep stable rotation, paddle integral body is rotated along shaft, material is also diffusion towards periphery centered by shaft, in the process of material diffusion, run into the baffle plate of being located on kettle sidewall, baffle plate produces a resistance to having the material of impulsive force, the directional-rotation of material is changed, decrease with its speed of material of baffle plate picture collision, therefore the rotary speed at the material of kettle inside has realized differentiation, therefore, realized the mixing between the material of different rotating speeds, now, material result has reached two kinds of mixed effects, it is the at the uniform velocity stirring of central stirring shaft, the material that sidewall baffle plate Yu Cong produces at center coordinates and then changes material speed realizes edge speed change stirring, in the process stirring, it is subject to range of resistance larger to the longer paddle of length, and the set reinforcement in the paddle back side is embodied in whipping process the support effect of paddle.

On kettle sidewall, be welded with polylith baffle plate, and baffle plate is axial curved face type, in the process that the material that is arranged so that close kettle sidewall of baffle plate rotates in kettle, be again subject to the impact of baffle plate, change its directed rotation direction, thereby make it more abundant in the mixing being subject to after baffle plate impacts, the design of curved surface has simultaneously expanded baffle plate impact area, and mixed effect is further improved.

Paddle is longitudinally oval, oval-shaped design makes paddle in the process stirring, reduced the resistance between paddle and material, meanwhile, with traditional individual layer paddle comparison, the degree of depth stirring is deepened to some extent, mixing effect is better, and upper and lower mixing between material bed is more easily realized, has avoided mixing with layer material up and down not reach desirable admixture, therefore, mixing effect is embodied.

The back side of paddle is provided with reinforcement along its length, the design of reinforcement make to be obstructed self intensity of larger paddle itself is strengthened to some extent, reduce the possibility of paddle fracture, and saved maintenance and the trouble of changing agitating device, improved operating efficiency.

Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
