Description

A multifunctional stirring device

technical field

The utility model relates to a stirring device, in particular to a multifunctional stirring device capable of simultaneously heating or cooling down.

Background technique

In the current chemical and pharmaceutical industry, many chemicals need to go through the three steps of filtration, washing and drying. Although there are currently some stirring devices that condense these three steps in one large device, the general method is pipeline heating, that is, heat transfer through pipeline loops, but the heat transfer efficiency of this method is low. , the heat is first transferred from the heat medium to the pipe, then from the pipe to the shaft and the blade, and then to the material, the waste of heat in the middle is serious.

Utility model content

The purpose of the utility model is to provide a multifunctional stirring device capable of drying or cooling materials while stirring, which has high heat conduction efficiency, saves working time and reduces production costs.

In order to achieve the above object, the utility model adopts the following technical solutions: a multifunctional stirring device, which includes a rotating main shaft and rotating blades arranged on the rotating main shaft, the rotating main shaft and the rotating blades are hollow, It also includes a water inlet pipe, a first sealed chamber, a second sealed chamber, a third sealed chamber and a return pipe.

The first sealed cavity, the second sealed cavity and the third sealed cavity are sequentially sealed and connected from top to bottom.

The water inlet pipe extends into the upper part of the first sealed chamber from above the first sealed chamber, the rotating main shaft penetrates the second sealed chamber from the bottom, and the third sealed chamber extends into the bottom of the first sealed chamber.

The return pipe communicates with the first sealing chamber, and extends downward from the top of the rotating main shaft to the root of the rotating blade, and then extends to the tip of the rotating blade respectively. The return pipe is at a position close to the tip of the rotating blade A return water outlet is provided.

The rotating main shaft in the second sealed chamber is provided with an inner water outlet, and the side wall of the second sealed chamber is provided with an outer water outlet.

The third sealed cavity is a power transmission box, which drives the internal rotating main shaft to rotate.

As a preferred solution of the multifunctional stirring device of the present invention, the part where the rotating spindle contacts the sealing cavity is sealed by a sealing device.

Compared with the prior art, the utility model has the following beneficial effects:

1. The structure is simple, the design is ingenious, and it is convenient to popularize and use on a large scale.

2. Save time, improve efficiency, and carry out washing and drying at the same time.

3. Two lines of hot and cold, heating and drying can be achieved by passing in the heat medium, and cooling can be achieved by passing in the refrigerant.

4. High heat conduction efficiency, large heat transfer area and strong fluidity.

detailed description

In order to further illustrate the technical means adopted by the utility model and the technical effects achieved, the following will be described in detail in conjunction with the accompanying drawings and embodiments.

The utility model provides a multifunctional mixing device, referring to Fig. 1, which includes a rotating main shaft 10, a rotating blade 20, a water inlet pipe 30, a first sealing chamber 40, a second sealing chamber 50, a third sealing chamber 60, return line 70 and sealing device 80 . The rotating blades 20 are arranged on the rotating main shaft 10, and the rotating main shaft 10 and the rotating blades 20 are hollow.

The first sealed cavity 40 , the second sealed cavity 50 , and the third sealed cavity 60 are sealed and connected sequentially from top to bottom, and the water inlet pipe 30 extends into the first sealed cavity 40 from above the first sealed cavity 40 In the upper part, the rotating spindle 10 penetrates the second sealed chamber 50 from the bottom, and the third sealed chamber 60 extends into the bottom of the first sealed chamber 40 and is sealed and isolated from the first sealed chamber 40 . The return pipe 70 communicates with the first sealing cavity 40, and extends downward from the top of the rotating main shaft 10 to the root of the rotating blade 20, and then extends to the tip of the rotating blade 20 respectively. A return water outlet 71 is provided near the blade tip. The rotating main shaft 10 in the second sealed chamber 50 is provided with an inner water outlet 11 , and the side wall of the second sealed chamber 50 is provided with an outer water outlet 51 . The third sealed chamber 60 is a power transmission box, which drives the rotating main shaft 10 inside to rotate. The part of the rotating spindle 10 in contact with the sealing cavity is sealed by a sealing device 80 .

The working principle of the utility model is: the heat medium flows into the first sealed chamber from the water inlet pipe, and then flows into the return pipe from the first sealed chamber. The heat medium flows down from the return pipe to the tip of the rotating blade, comes out from the outlet of the return water, enters the hollow rotating blade and the rotating main shaft, and then overflows upwards to the inner water outlet of the second seal chamber and flows into the second seal. chamber, and then flow out from the outlet of the second sealed chamber.

The advantage of the utility model is that the heat medium flows out from the return pipe to the hollow rotating blade and the rotating main shaft, the heat exchange area increases, and with the rotation of the blade, the overall fluidity is greatly enhanced, making the heat exchange more rapid. If it is replaced with refrigerant, the effect is the same.

The above description has fully disclosed the specific implementation manners of the present utility model. It should be pointed out that any changes made by those skilled in the art to the specific embodiments of the utility model will not depart from the scope of the claims of the utility model. Correspondingly, the scope of the claims of the present utility model is not limited only to the foregoing specific embodiments.
