Description

Technical Field

[0001] This utility model belongs to the field of agitator technology, and specifically relates to an agitator suitable for corn stalks. Background Technology

[0002] Corn stalks, as a major biomass waste generated in agricultural production, are characterized by their wide range of sources and large total volume. Converting corn stalks into biogas, bio-organic fertilizer, and other products through microbial fermentation technology can not only realize the resource utilization of waste and reduce environmental pollution, but also provide clean energy and high-quality fertilizer for agricultural production, which is of great significance for promoting the development of a circular economy in agriculture.

[0003] Currently, before fermenting corn stalks, they need to be crushed first to break the whole stalks into small pieces to increase the contact area between the stalks and the fermentation liquid and microorganisms. After crushing, the stalk pieces are poured into the fermentation tank, and fermentation liquid and bacteria are added for fermentation. To ensure that the stalk pieces can be fully mixed with the fermentation liquid during the fermentation process and to avoid uneven contact of local materials affecting the fermentation effect, a stirrer is usually added inside the fermentation tank. The dynamic mixing of materials is achieved through the continuous operation of the stirrer. However, most of the existing fermenters currently use traditional single-shaft agitators, and their agitation capacity is insufficient. Since corn stalks have poor fluidity and the tanks are generally large, agitators with strong agitation capacity and good agitation performance are needed to be suitable for agitating corn stalks.

Detailed Implementation

[0017] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0018] Example 1: As Figure 1-4 As shown in the figure, the present invention provides a mixer suitable for corn stalks, including a drive assembly, an inner mixing assembly, and an outer mixing assembly. The drive assembly drives the inner and outer mixing assemblies to rotate. The inner mixing assembly includes an inner rotating shaft 21 and a plurality of inner mixing blades 22 distributed on the rotating shaft 21. The inner mixing blades mix the material to the outside. The outer mixing assembly includes an outer rotating sleeve 31, a mixing frame 32, and a plurality of first mixing blades 33 arranged on the mixing frame 32. The inner rotating shaft 21 and the outer rotating sleeve 31 are coaxially arranged, and the outer rotating sleeve 31 is sleeved on the inner rotating shaft 21.

[0019] Specifically, the inner stirring blade 22 includes an inclined "T"-shaped stirring blade 221 and an inner inclined blade 222 on the inclined "T"-shaped stirring blade 221. The inclination direction of the "T"-shaped stirring blade 221 and the inner inclined blade 222 are opposite. The opposite inclination direction makes the stirring direction opposite, which can improve the stirring effect. The inclination angle of the "T"-shaped stirring blade 221 to the stirring plane is between 30 and 60 degrees, and the inclination angle of the inner inclined blade 222 is between 60 and 30 degrees. In this embodiment, a 45-degree inclination angle is used, that is, the "T"-shaped stirring blade 221 and the inner inclined blade 222 are set perpendicularly. One end of the "T"-shaped stirring blade 221 is connected to the inner rotating shaft 21.

[0020] Specifically, the stirring frame 32 includes a circumferential array of vertical rods 321, a plurality of first connecting rods 322 for sequentially connecting the vertical rods 321, and a second connecting rod 323 for connecting the vertical rods 321 to the outer rotating sleeve 31. In this embodiment, there are three vertical rods 321, that is, the stirring frame 32 is triangular in shape. The triangular structure has very good stability, so it can be used for large-diameter and heavy-load stirring and can ensure strength.

[0021] Specifically, the first stirring blade 33 is inclinedly arranged on the vertical rod 321, and a plurality of first stirring blades 33 are arrayed along the height direction of the vertical rod 321. The first connecting rod 322 is inclinedly provided with a second stirring blade 34, the inclination direction of the second stirring blade 34 is opposite to the inclination direction of the first stirring blade 33, and its design principle is the same as that of the "T"-shaped stirring blade 221 and the inner inclined blade 222, all of which are to improve the stirring effect. The inclination angle of the first stirring blade 33 is between 30 and 60 degrees, and the inclination angle of the second stirring blade 34 is between 60 and 30 degrees. In this embodiment, a 45-degree inclination angle is also used.

[0022] Specifically, the drive assembly includes an inner drive assembly and an outer drive assembly. The inner rotating shaft 21 and the outer rotating sleeve 31 are driven by the inner drive assembly and the outer drive assembly respectively, and the driving directions are opposite. The inner drive assembly includes an inner drive motor 41 and an inner drive mounting bracket 42. The inner drive motor 41 is mounted on the inner drive mounting bracket 42, and its output end is connected to the inner rotating shaft 21.

[0023] Specifically, the external drive assembly includes a rotary support 43 for an external gear ring and an external drive motor 44 for driving the rotary support 43 to rotate. The inner rotating shaft 21 passes downward through the center of the rotary support 43. The external drive motor 44 and the inner drive mounting bracket 42 are supported and mounted by a drive mounting seat 45.

[0024] The external drive motor 44 is a multiple parallel circular array. This structure can achieve uniform stirring and avoid imbalance, which would cause uneven force on the stirring component. This is very important for large-diameter stirring components.

[0025] In some embodiments, to prevent materials from sinking to the bottom, the lower end of the inner rotating shaft 21 is connected to the bottom stirring blade 5.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
