[0002] Conventional wet garbage degradation equipment usually has a stirring shaft installed in a mixing chamber, through which the wet garbage is stirred to increase the contact area between the wet garbage and the degradation microorganisms in the mixing chamber, thereby improving the degradation effect of the wet garbage.

[0003] However, the conventional stirring shaft can usually only stir the wet garbage in the radial direction, which is not sufficient.

[0024] The spiral channel formed by the traditional spiral stirring shaft is usually a channel of equal diameter, which can only realize the axial movement of wet garbage, but cannot stir the wet garbage in the axial direction, the stirring is not sufficient, and the stirring effect is relatively poor. The present invention provides a stirring shaft structure of wet garbage degradation equipment, which has a simple structure and ingenious design. By setting two variable diameter spiral channels in opposite directions, the stirring shaft can stir the wet garbage both radially and axially, and the stirring is sufficient and the stirring effect is good.

[0025] The stirring shaft structure of the wet garbage degradation equipment is further explained below in conjunction with the accompanying drawings.

[0026] See also Figure 1 , Figure 1 The diagram shows the corresponding structure of the stirring shaft and the discharge port of the wet garbage degradation device of the present invention.

[0027] The present invention is implemented by the following scheme: A stirring shaft structure of a wet garbage degradation device includes a first stirring shaft 10 and a second stirring shaft 20 installed side by side in a stirring bin, and the stirring bin is provided with a discharge port 30, wherein:

[0028] The first stirring shaft 10 is fixed with a plurality of first stirring blades along a positive spiral trajectory, and a first spiral channel with a variable diameter is formed between the plurality of first stirring blades;

[0029] The second stirring shaft 20 is fixed with at least one output blade and a plurality of second stirring blades along a reverse spiral trajectory. The output blade corresponds to the height of the discharge port 30, and a second spiral channel of variable diameter is formed between the output blade and the plurality of second stirring blades for transporting wet garbage to the discharge port 30.

[0030] Specifically, the shaft cores of the first stirring shaft 10 and the second stirring shaft 20 are both made of hollow seamless stainless steel tubes;

[0031] Cooperate Figure 2 and Figure 3 , Figure 2A front view showing a structural comparison of a first stirring shaft and a second stirring shaft in the stirring shaft structure of the wet garbage degradation device of the present invention; Figure 3 The structure comparison top view of the first stirring shaft and the second stirring shaft in the stirring shaft structure of the wet garbage degradation equipment of the present invention is shown. In this embodiment, the first stirring shaft 10 is welded and fixed with 8 first stirring blades 11 to 18 evenly spaced along the axial direction of the first stirring shaft 10 according to a left spiral trajectory (i.e., a clockwise circular motion trajectory);

[0032] The second stirring shaft 20 has two output blades 22, 23 and six second stirring blades 21, 24-28 welded and fixed at uniform intervals along the axial direction of the second stirring shaft 20 according to a right spiral trajectory (i.e., a counterclockwise circular motion trajectory). The fixed heights of the two output blades 22, 23 are within the height range of the discharge port 30, and when the two output blades 22, 23 are rotated to a position facing the discharge port 30, the ends of the two output blades 22, 23 extend to the position of the discharge port 30. Through the two output blades 22, 23 and utilizing the rotation of the second stirring shaft 20, an automatic discharging function can be realized, which greatly reduces labor costs and improves discharging efficiency.

[0033] When the first stirring shaft 10 and the second stirring shaft 20 are installed side by side in the stirring chamber of the wet garbage degradation equipment, the fixed positions of the eight first stirring blades 11 to 18 are respectively opposite to the fixed positions of the two output blades 22, 23 and the six second stirring blades 21, 24 to 28 (i.e., 11 to 18 are respectively opposite to 21 to 28).

[0034] The coordinated arrangement of the two variable diameter spiral channels in opposite directions ensures that in the diameter direction, with each rotation, the eight blades on the first stirring shaft 10 and the eight blades on the second stirring shaft 20 continuously form a mixing effect of extrusion, shearing and shredding in pairs. In the axial direction, the flow and impact of the wet garbage in the mixing bin are further intensified, which not only enhances the mixing capacity but also improves the mixing efficiency.

[0035] The above is only a preferred implementation mode. The number of blades, the fixed position, and the variable diameter settings of the first spiral channel and the second spiral channel can be calculated and adjusted according to actual conditions. However, it should be noted that the stirring effect and the weight of the stirring shaft should be taken into account so that the stirring shaft has a better stirring effect while ensuring its service life. After calculation and verification, the present invention has the best effect when the number of blades on each stirring shaft is 8 to 10.

[0036] As a preferred embodiment, the two output blades 22 and 23 are respectively arranged at an angle of 45 degrees and 135 degrees with the axial direction of the second stirring shaft along the width direction.

[0037] For the automatic discharging function, the two output blades 22 and 23 are designed with angles of 45 degrees and 135 degrees, so as to achieve a smoother discharging effect without reducing the good stirring effect.

[0038] As a preferred embodiment: Figure 2 As shown, the eight first stirring blades 11 to 18 are alternately arranged along the width direction to form a first angle a and a second angle b with the axial direction of the first stirring shaft 10;

[0039] The plurality of second stirring blades are alternately arranged along the width direction at a first angle a and a second angle b with respect to the axial direction of the second stirring shaft.

[0040] Specifically, the first angle a is 45 to 60 degrees, the second angle is 120 to 135 degrees, and the first angle a is complementary to the second angle b. Further, the first angle a is 60 degrees, and the second angle b is 120 degrees. In addition, the length direction of each blade (including the first stirring blade, the second stirring blade and the output blade) is perpendicular to the axial direction of the corresponding first stirring shaft 10 or the second stirring shaft 20. With the setting of the first angle a, the setting of the second angle b and the setting of the angle of the output blade, the eight blades on the same stirring shaft are inclined towards each other and the angles are opposite, thereby forming a spiral channel with a variable diameter, so that when the solid wet garbage is stirred, a counter-attack effect can be formed in the stirring bin, which ensures a good stirring effect on the one hand, and limits the resistance of the wet garbage to the first stirring blade and the second stirring blade during stirring on the other hand, reduces the loss of the two and ensures the service life.

[0041] As a preferred embodiment: Figure 2 As shown, the ends of the eight first stirring blades 11 to 18 and the ends of the six second stirring blades 21 , 24 to 28 are provided with a first scraper 001 , and the ends of the two output blades 22 , 23 are provided with a second scraper 002 , and the size of the second scraper 002 is larger than that of the first scraper 001 .

[0042] By setting the scraper, the contact area between the blades and the wet garbage is increased, and the stirring effect is improved. Furthermore, by increasing the size of the second scraper 002, the wet garbage can be discharged more quickly and thoroughly, thereby improving the discharge effect and efficiency.

[0043] As a preferred embodiment: microorganisms for degrading wet garbage are arranged in the mixing chamber. The wet garbage is degraded by the microorganisms, and the mixing shaft structure is used to improve the degradation effect.

[0044] The present invention cooperates with two variable diameter spiral channels in opposite directions, so that the two stirring shafts can stir the wet garbage both radially and axially, so that the solid wet garbage can form a hedging effect in the stirring bin, so that the stirring is more sufficient and the stirring effect is better, thereby achieving the best degradation and other treatment effects. In addition, the present invention limits the angle of the output blade corresponding to the height of the discharge port, limits the extension length of the end, and enlarges the size of the scraper at the end, so that the stirring shaft structure can better cooperate with the discharge port for discharge.

[0045] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
