In view of the above problems, it is an object of the present invention to provide a screw agitating device which solves any of the above problems.

A spiral agitating device, comprising: a motor, a stirring kettle and a stirring paddle, wherein the agitating paddle comprises a stirring shaft and a stirring blade, wherein the stirring blade is arranged in a spiral structure at the stirring At a first end of the shaft, a first end of the agitating shaft is located in the agitating tank, and a second end of the agitating shaft extends outside the agitating tank and is connected to the motor.

Wherein, the spiral stirring device further comprises a heating pipe, the heating pipe is arranged in a spiral shape in the stirring kettle, and an inlet and an outlet of the heating pipe are disposed outside the stirring kettle.

Wherein, the height of the heating pipe is 1/5 to 3/5 of the height of the stirring kettle.

Wherein the spiral diameter of the stirring blade is smaller than the spiral diameter of the heating pipe.

Wherein, the spiral diameter of the stirring blade is 1/4-1/3 of the diameter of the stirring kettle.

Wherein the height of the stirring blade is smaller than the height of the stirring tank, and both ends of the stirring blade are suspended from the end of the stirring kettle.

Wherein, the material of the stirring blade is carbon steel or stainless steel.

Wherein, the spiral stirring device is suitable for stirring of an amine sheet or a paste article.

The invention has the advantages that the invention adopts a novel spiral stirring device, and when the paste-like or sheet-shaped anti-caking agent encounters the propeller blade of the stirring paddle, the anti-caking agent solid is directly cut, and the cutting effect is good. Compared with the traditional folding blade type paddle, the resistance is small, the agitation area is increased, and because of the small resistance, the motor connected to the paddle is easily driven, the heat loss is low, and the efficiency of the motor is high. The stirring efficiency of the stirring paddle is high.

Other characteristics and advantages of the present invention will become apparent from the following description of the exemplary embodiments.

The drawings in the following description are some embodiments of the invention, rather than all embodiments. Other figures may be obtained from those of ordinary skill in the art in light of the inventive work.

Fig. 1 exemplarily shows a structural view of a screw agitating device of the present invention.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The basic idea of the invention is to improve the agitator paddle of the agitator by solving the above problems by using a novel spiral structure.

The spiral stirring device will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , the present invention provides a spiral stirring device, which may include a motor 1 , a stirring pot 2 and a stirring paddle 3 , wherein the agitating paddle 3 includes a stirring shaft 32 and a stirring blade 31 , and the stirring blade 31 is The spiral structure is disposed at the first end 321 of the agitating shaft 32. The first end 321 of the agitating shaft 32 is located in the agitating tank 2, and the second end 322 of the agitating shaft 32 extends out of the agitating tank 2 and is connected to the motor 1.

According to the actual production requirements, the anti-caking agent also needs to be heated to facilitate the subsequent spraying of the fertilizer, so the spiral stirring device may further comprise a heating pipe 4, the heating pipe 4 is spirally arranged in the agitating tank 2, and the heating pipe is heated The inlet 41 and the outlet 42 of 4 are both disposed outside the stirred tank 2.
