Description

Flexible stirring device

Technical Field

The invention relates to the field of stirring devices, in particular to a flexible stirring device.

Background

Stirring is an indispensable link in industrial production, whether solution and mixed liquid can be quickly and fully stirred can influence the working efficiency, and the important factor of the effective energy utilization rate is also influenced, so that the production benefit of important enterprises is influenced. At present, most of stirring mechanisms used in China are stirring mechanisms of paddle structures using motors as power, are complex in structure, strong in crushing performance on stirring media and not suitable for stirring media sensitive to crushing performance. In the production process of traditional Chinese medicine, for example, the medicinal materials are often not destroyed by stirring, and stirring of the traditional Chinese medicine is an important factor influencing the extraction efficiency and the extraction rate of effective components in the production of the traditional Chinese medicine.

Disclosure of Invention

The invention aims to provide a flexible stirring device which can reduce the damage to a stirring medium in the stirring process.

To solve the above problems, an aspect of the present invention provides a flexible stirring apparatus, including: the stirring barrel is a hollow stirring shaft arranged inside the stirring barrel through a rotary joint, the rotary joint is arranged at the top end of the stirring barrel through a fixed support, the other end of the rotary joint is connected with a fluid inlet, an injection mechanism is arranged on the hollow stirring shaft, and the direction of a nozzle of the injection mechanism is not larger than the axis of the hollow stirring shaft. Stirring fluid enters from the fluid inlet and then reaches the inside of the hollow stirring shaft through the rotary joint, the stirring fluid is sprayed out from the spraying mechanism arranged on the hollow stirring shaft, and the initial speed direction of the stirring fluid and the outer circumference of the hollow stirring shaft form a certain included angle during spraying, so that the reaction force sprayed out from the spraying mechanism by the stirring fluid can enable the hollow stirring shaft to start rotating. The effect of stirring the medium in the stirring barrel can be achieved, and the stirring of the medium by the stirring fluid is completed through the flowing of the stirring fluid, so that the medium cannot be damaged, and the effect of soft stirring is achieved. Wherein the rotary joint is a sealed rotary connector for conveying media in a 360-degree rotary mode and can be directly purchased. The category of the stirring fluid is selected according to actual production requirements, such as no pollution to the stirring medium, no physical or chemical reaction with the stirring medium, no change of the concentration of the stirring medium and the like.

According to a further technical scheme, the stirring fluid is liquid or gas with pressure. The stirring fluid may be, but is not limited to, a liquid or a gas with pressure. The stirring fluid does not contaminate the stirring medium or the stirred material to be stirred, and is preferably water, air, nitrogen, carbon dioxide, or the like.

According to a further technical scheme, the stirring fluid spraying mechanism comprises an inclination angle joint and a flow regulating spray head arranged on the inclination angle joint. The angle of the spraying mechanism for spraying the stirring fluid can be adjusted by replacing the dip angle joints with different dip angles, so that the stirring speed of the hollow stirring shaft can be controlled. Wherein the tilt angle joint may be a bent tubular joint having a certain tilt angle. The pressure of the stirring fluid is selected according to the requirements of stirring speed, crushing rate of the stirring medium, stirring radius and the like. The flow regulating nozzle can be a pressure regulating valve, if the pressure of the pressure regulating valve is increased, the flow flowing to the nozzle is increased, otherwise, the flow is opposite, and therefore the flow of the stirring fluid sprayed out in unit time can be regulated. The flow rate can also be varied by varying the operating pressure of the mixing fluid, the flow rate increasing the greater the pressure of the mixing fluid fed, and vice versa. The pressure of the stirring fluid sprayed from the stirring fluid spraying mechanism is higher, the initial speed of the spraying fluid is higher, the stirring shaft can rotate at a higher speed, and the stirring acting force on the medium in the stirring barrel is higher.

The further technical proposal is that the device also comprises a storage barrel for storing and stirring the fluid, and the storage barrel is connected with the fluid inlet through a pressure regulating pump. When the stirring fluid is liquid, the stirring fluid can be stored in the storage barrel, the stirring fluid in the storage barrel is pumped into the fluid inlet through the pressure regulating pump, and then is sprayed out through the hollow stirring shaft and the spraying mechanism to enter the stirring barrel. When the stirring fluid is gas, the gas can be pumped into the stirring barrel through the gas pump, and finally the gas is discharged by arranging the gas outlet on the stirring barrel.

A further technical scheme is that a backflow port for stirring fluid is arranged on the stirring barrel, the backflow port is connected to the storage barrel through a pipeline, and an anti-blocking net is further installed at the backflow port. The anti-blocking net can prevent the stirring medium from flowing into the storage barrel through the backflow port.

The further technical proposal is that a stirring rod is also arranged outside the hollow stirring shaft. And when the hollow stirring shaft is pushed by stirring fluid to rotate, the stirring rod can also be used for carrying out auxiliary stirring on the stirred material. Wherein the stirring rod can be made of flexible materials, and the stirring medium cannot be broken.

The further technical proposal is that the bottom of the hollow stirring shaft is provided with a plurality of spray nozzles with the nozzle direction parallel to the axis of the hollow stirring shaft. The axis of spray nozzle spout direction and hollow mixing shaft is parallel, and is sprayed direct injection to the agitator bottom from the spray nozzle when stirring the fluid, then upwards forms the stirring vortex along the agitator bottom, just so can stir the agitator bottom, prevents to stir the medium and deposit in the agitator bottom.

The technical scheme is that the device further comprises a pneumatic press pipe, and the pneumatic press is connected with the fluid inlet through a pipeline. Air can be pumped into the stirring barrel as stirring fluid by an air compressor to stir the stirring medium.

The principle of the invention is explained as follows: stirring fluid has during certain pressure can enter into hollow mixing shaft through rotary joint, the epaxial injection mechanism blowout of rethread hollow mixing shaft, and the nozzle direction and the outer circumference of hollow mixing shaft of spraying mechanism have certain contained angle, hollow mixing shaft receives the influence of its reaction force to begin to rotate when stirring fluid blowout, stirring fluid is still outwards spouting continuously at hollow mixing shaft rotation in-process, stirring fluid just can play the stirring effect to the material in the agitator, because stirring fluid is not rigid material, consequently can not produce serious stirring to being destroyed by the stirring.

The technical scheme of the invention has the following beneficial technical effects: simple structure, if to the fragmentation nature of stirring medium, stirring that can be gentle is to the sensitive stirring medium of fragmentation nature.
