Description

Technical Field

[0001] The utility model relates to a fermentation silo used for horizontal fermentation, belonging to the technical field of fermentation devices. Background Art

[0002] High-temperature aerobic fermentation of livestock and poultry manure can kill harmful components such as pathogens, insect eggs, and weed seeds, promoting the full decomposition and transformation of the organic matter it contains. The fermented material, after further aging and composting, can then be returned to the field for use. This is currently an important means of controlling manure pollution and producing organic fertilizer. During the horizontal aerobic fermentation process, the fermentation silo primarily serves as a place for feeding, storing, mixing, temperature regulation, oxygen supplementation, high-temperature rapid fermentation, and discharging livestock and poultry manure. It works in conjunction with agitators, oxygen supplementation, and temperature control systems to complete the fermentation of livestock and poultry manure. The integrity and stability of the fermentation silo are crucial.

[0003] For example, in a horizontal fermentation silo, the agitator is installed horizontally, with both ends supported on the silo. This inevitably causes the agitator to wobble during rotation, especially when livestock and poultry manure contains high solids. This further increases the unbalanced forces acting on the agitator during rotation, which are then transmitted to the silo. Furthermore, livestock and poultry manure is corrosive, exacerbating silo corrosion under high temperatures and aerobic conditions. Therefore, fermentation silos must meet specified corrosion resistance and structural strength requirements. Failure to do so can result in localized corrosion, deformation, or reduced sealing.

DETAILED DESCRIPTION

[0021] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways other than those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-Figure 4 As shown in the figure, the fermentation silo for horizontal fermentation provided by the present invention is formed by a side panel 100 and a first end panel 210 and a second end panel 220. The side panel 100 encloses an area with openings at the top and both longitudinal ends. The vertically arranged first end panel 210 and second end panel 220 are respectively sealed at both longitudinal ends of the side panel 100 to form a cavity with an opening at the top for the fermentation material to be placed in.

[0024] Specifically, the side panel 100 includes an arc-shaped panel 110 with an arc-shaped cross-section. The arc-shaped panel 110 arches downward into an arc shape, and vertical side panels 120 extend from the top of each lateral side of the arc-shaped panel 110. As will be understood, an arc is a segment of a circle, and the longitudinal direction of the arc-shaped panel 110 is perpendicular to the diameter of the arc. The arc-shaped panel 110 is generally formed by rolling a steel plate.

[0025] The shapes of the first end plate 210 and the second end plate 220 match the shapes of the longitudinal openings at both ends of the arc-shaped warehouse plate 110, that is, the lower contours of the first end plate 210 and the second end plate 220 are arc-shaped, and the first end plate 210 and the second end plate 220 are sealed and assembled into one with the side panel 100 by welding.

[0026] The fermentation silo provided by the present invention is suitable for a horizontal fermentation device, wherein the stirring shaft is installed horizontally, and stirring shaft mounting holes 300 are provided on the first end plate 210 and the second end plate 220. The first end plate 210 and the second end plate 220 are each composed of an inner plate 201 and an outer plate 202. The inner plate 201 is located on the inner wall of the fermentation silo, and the outer plate 202 is located on the outer wall of the fermentation silo. The outer plate 202 is provided with a plurality of through holes 203, each of which has a diameter of approximately 10 mm. The outer plate 202 and the inner plate 201 are welded together at the through holes 203. After welding, the through holes 203 are filled with a curing slurry, such as a polyurethane filler or an inorganic grouting material, to smooth the surface.

[0027] Inner plate 201 and side panels 100 are made of stainless steel, such as 304 stainless steel, for its high corrosion resistance. Outer plate 202 is made of carbon steel, which offers high hardness and strength. In practice, inner plate 201 is thinner than outer plate 202, and the surface of the fermentation silo is painted with anti-rust paint.

[0028] The utility model combines a stainless steel inner plate 201 with a carbon steel outer plate 202 to form a first end plate 210 and a second end plate 220 , thereby meeting the corrosion resistance and strength requirements of the first end plate 210 and the second end plate 220 .

[0029] In addition to the stirring shaft mounting hole 300, the first end plate 210 and the second end plate 220 are usually also provided with mounting interfaces for temperature, pressure, pH sensors, etc. Moreover, the first end plate 210 and the second end plate 220 are important connecting parts with the external support frame and are important parts for supporting the weight of the fermentation silo, and are required to have good structural strength.

[0030] In addition, the temperature inside the fermentation silo is high during the fermentation process, and the temperature of the fermentation silo is lower when it is not working. The fermentation silo will expand and contract due to heat. If the inner plate 201 and the outer plate 202 are not tightly connected, the gap between the inner plate 201 and the outer plate 202 will change, causing the first end plate 210 and the second end plate 220 to deform, resulting in local stress concentration and affecting the installation sealing of the stirring shaft and the sensor.

[0031] To this end, the utility model connects the inner plate 201 and the outer plate 202 by multi-point welding, which improves the connection strength between the two, enhances the compressive resistance of the first end plate 210 and the second end plate 220, prevents deformation, and enables the fermentation silo to operate stably for a long time.

[0032] In a preferred embodiment, a heating oil tank 400 is welded to the outer wall of the curved silo 110. The upper and lower portions of the heating oil tank 400 are provided with an oil inlet 410 and an oil drain 420, respectively. Thermal oil at a predetermined temperature enters the heating oil tank 400 through the oil inlet 410 and flows out through the oil drain 420. As it flows through the heating oil tank 400, it exchanges heat with the material within the fermentation silo, raising the temperature of the material within the silo. To facilitate maintenance and reduce the possibility of dead zones, multiple independent heating oil tanks 400 are typically provided, each located on the left and right sides of the curved silo 110.

[0033] It can be understood that a discharge port 130 is provided at the bottom of the arc-shaped bin plate 110. In actual application, a cover plate is usually fastened on the top of the fermentation silo, and a feed port is provided on the cover plate. The end of the stirring shaft passes through the stirring shaft mounting hole 300, and a stirring blade is installed on the stirring shaft. The material is added to the fermentation silo from the feed port, and the rotation of the stirring shaft drives the stirring blade to toss the material so that the material is evenly mixed. The fermentation silo is circular in shape, and the stirring blade rotates against the inner wall of the fermentation silo, which can reduce the dead angle of stirring. During the fermentation process, the fermentation temperature of the material is adjusted by heating the thermal oil in the oil bin 400. After the fermentation is completed, the material is discharged from the discharge port 130.

[0034] Preferably, the upper portions of the vertical side panels 120 on both sides are connected by a plurality of cross beams 500 , which act as reinforcing ribs to prevent the fermentation silo from deforming and to support a cover plate disposed on the top of the fermentation silo.

[0035] Typically, for a large-capacity fermentation silo, the arc-shaped silo plate 110 , the vertical side plates 120 , the first end plate 210 , and the second end plate 220 are formed by splicing and welding a plurality of unit plates.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "lateral", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In this utility model, unless otherwise specified or limited, terms such as "disposed," "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; and direct connection or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0038] Anything not described in detail in the present invention is well known to those skilled in the art.
