Description

Fermentation equipment

Technical Field

The invention relates to fermentation equipment, in particular to fermentation equipment for performing a decomposition process in a layered mode.

Background

At present, organic materials, such as food or kitchen waste of agricultural products, livestock products, fishery products and the like, can return to nature after being properly treated, or can be recycled as precious organic nutrients in soil. If the organic material is to be used as a fertilizer, it is usually necessary to decompose the organic material to form a fertilizer over a period of time. In order to decompose the organic materials uniformly, the process of decomposition of the organic materials is performed by continuously turning the organic materials, so that the organic materials are decomposed smoothly.

In the early stage, long channels are dug out on the ground to serve as fermentation spaces, but the diffusion range of peculiar smells is too wide due to overlarge occupied area and long fermentation time (about one month), so that the vertical barrel is adopted as the fermentation space in the industry, the occupied area is reduced, and the decomposition time of the organic materials can be accelerated.

As shown in fig. 1, the conventional fermenter 9 contains organic materials and required microorganisms, and the rotation F of the stirrer 90 is utilized to stir and turn the organic materials in the fermenter 9, and then the temperature and humidity of the fermenter 9 are controlled by the heater 91 (as shown in the figure, the heat supply path T) to effectively decompose the microorganisms in the fermenter 9, so that the organic materials can be automatically decomposed by setting the operation cycle of the stirrer 90 to periodically perform the stirring operation.

However, in the conventional fermenter 9, the agitator 90 often only rotates at the bottom of the fermenter 9 to stir the organic material, so that the organic material in each region cannot be uniformly decomposed in the conventional fermenter 9, for example, the decomposition time of the region close to the agitator 90 (such as the bottom region) is fast, the decomposition time of the region far away from the agitator 90 (such as the top region) is slow, and thus the material in the top region needs to be waited for slowly decomposing, so that the fermentation operation time of a single fermenter 9 is difficult to be shortened.

In addition, the speed of rotation of the agitator 90 also affects the disintegration time. If the rotation speed of the stirrer 90 is too slow, the heat energy distribution is not uniform, for example, the heat energy is concentrated in the bottom region, so that the decomposition time course of the bottom region is faster than that of the top region; if the rotation speed of the stirrer 90 is too high, the heat energy is rapidly dissipated, so that the temperature in the barrel is too low, and the microorganisms are killed.

In view of the above, it is an object of the present invention to provide a fermentation device, which overcomes the above problems.

In order to solve the problems of the prior art, the invention provides fermentation equipment which can uniformly decompose various batches of materials.

The fermentation apparatus of the present invention comprises: the first action device comprises a first containing groove with a first opening and at least one first stirring component arranged in the first containing groove, wherein the first stirring component is provided with a first action piece; the second action device comprises a second containing groove with a second opening and at least one second stirring component arranged in the second containing groove, and the first containing groove is stacked on the second containing groove, wherein the position of the first opening is not aligned with the position of the second opening, and the second stirring component is provided with a second action sheet; the power device is used for linking the first stirring component and the second stirring component.

In the fermentation apparatus, the first opening is located in the middle of the first accommodating groove.

In the fermentation apparatus, the second opening is located at an edge of the second accommodating groove.

In the fermentation apparatus, the first action piece and the second action piece are disposed in a staggered manner. For example, the first active piece is tilted, and the second active piece is tilted in the opposite direction of the first active piece.

In the fermentation apparatus, the first stirring assembly is further provided with a first rod for erecting the first action pieces, and the first action pieces are inclined relative to the axis of the first rod to form a plurality of first included angles. For example, at least two of the first included angles are different.

In the fermentation apparatus, the second stirring assembly is further provided with a second rod for erecting the second action pieces, and the second action pieces are inclined relative to the axis of the second rod to form a plurality of second included angles. For example, at least two of the plurality of second included angles are different.

In the fermentation apparatus, the power device is disposed on the plurality of first action devices and the plurality of second action devices.

Therefore, the fermentation equipment provided by the invention has the advantages that by means of the combined layered design of the first action device and the second action device, and under the condition that the position of the first opening is not aligned with the position of the second opening, each batch of materials can move from the upper layer to the lower layer to stir, so that compared with the prior art, the fermentation equipment provided by the invention can avoid the problem that the materials are accumulated in an upper accommodating space, so that each batch of materials can be uniformly decomposed, the decomposition time courses of each batch of materials are almost the same, and the time of a fertilizer manufacturing process is effectively shortened and the quality of the fertilizer is controlled.

In addition, the first action pieces and the second action pieces are arranged in a staggered manner, so that the materials move in a speed-speed staggered manner of gradually increasing (such as the first action device is pushed from outside to inside) and gradually decreasing (such as the second action device is pushed from outside to inside) when the upper layer and the lower layer move, and the heat energy is evenly distributed or the fermentation (decomposition) time course is evenly distributed, so that compared with the prior art, the fermentation equipment disclosed by the invention can avoid the problem that the rotation speed of the power device influences the decomposition time course.

In addition, the fermentation equipment of the invention is not limited by the size of the fermentation place by means of the combined layered design, and the amount of the odor gas generated in the decomposition process can be greatly reduced because the material can move to the lower layer for decomposition, so that the fermentation volume can be increased or decreased according to the requirement to produce the required fertilizer amount, and compared with the prior art, the field suitable for fermentation operation is easy to find by adopting the fertilizer produced by the invention.

In addition, the terms such as "upper", "lower", "left", "right", "front", "rear", "first", "second" and "first" used in the present specification are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial technical changes.

FIGS. 2A to 2C are schematic views of a fermentation apparatus 1a of the present invention. As shown in fig. 2A to 2C, the fermentation apparatus 1a is vertical, and includes a first acting device 1, a second acting device 2 and a power device 3.

The first acting device 1 includes a first receiving groove 11 and a first stirring component 12, as shown in fig. 2A and fig. 3A.

In the embodiment, the first receiving groove 11 is used for receiving materials for producing fertilizer, such as kitchen waste, microorganisms or other suitable components, and the first receiving groove 11 has a circular plate 11a and a wall structure 11c surrounding the edge of the plate 11a to form a receiving space S1 having a notch 11b, such that the plate 11a and the notch 11b are respectively located at two opposite sides (upper and lower sides) of the first receiving groove 11, and a first opening 110, such as a circular hole, is formed in the middle of the plate 11 a.

In addition, the first stirring component 12 is disposed in the first accommodating cavity 11 and has a first rod 120, at least one first acting sheet 121 disposed on the first rod 120, and a first shaft 122 disposed on the first rod 120 (e.g., at the middle of the rod), and the first shaft 122 is disposed above the first opening 110. As shown in fig. 2A, the first rod 120 of the first stirring assembly 12 is provided with a plurality of first acting pieces 121, such that the plurality of first acting pieces 121 are disposed obliquely towards the front, and when the first rod 120 rotates relative to the first shaft 122, the plurality of first acting pieces 121 can push the material in the first containing groove 11 towards the first opening 110, such that the material leaves the first containing groove 11 from the first opening 110.

In addition, the first active plate 121 is a plate with a rectangular surface, and the rectangular surface may be a flat surface or an inclined surface.

In addition, the first rod 120 extends in the forward direction relative to the first action pieces 121 on the opposite sides (left and right sections) of the first shaft 122, as shown in fig. 3A. For example, the first action pieces 121 each project the shaft of the first lever 120 in the counterclockwise direction toward the wall structure 11 c.

The second acting device 2 and the first acting device 1 are stacked, and the second acting device 2 includes a second receiving groove 21 and a second stirring component 22, as shown in fig. 2A and 3B.

In the embodiment, the volume and the appearance of the second receiving groove 21 are substantially equal to those of the first receiving groove 11, so that the first receiving groove 11 and the second receiving groove 21 can be covered with each other, and the second receiving groove 21 has a circular plate 21a and a wall structure 21c surrounding the edge of the plate 21a, so as to form a receiving space S2 having a notch 21b, so that the plate 21a and the notch 21b are respectively located at two opposite sides (upper and lower sides) of the second receiving groove 21, and at least one second opening 210 located in the receiving space S2 is formed at the edge of the plate 21a of the second receiving groove 21, wherein the plate 11a of the first receiving groove 11 covers the notch 21b of the second receiving groove 21, and the first opening 110 is communicated with the receiving space S2 of the second receiving groove 21. For example, the plate body 21a has a plurality of second openings 210, such as curved grooves, and the second openings 210 are arranged at intervals (may be equally spaced) along the edge (circular path) of the plate body 21a to form a discontinuous ring shape. It should be understood that the second opening 210 can also form a continuous ring-shaped second opening 210 as required, so the shape or number of the second openings 210 can be designed as required, and is not particularly limited.

In addition, the second stirring component 22 is disposed in the second receiving groove 21 and has a second rod 220, at least one second acting piece 221 disposed on the second rod 220, and a second shaft 222 disposed on the second rod 220 (e.g., at the middle of the rod body), and the second acting piece 221 is disposed obliquely along the reverse direction (i.e., toward the rear) of the first acting piece 121. As shown in fig. 2A, the second rod 220 of the second stirring assembly 22 is configured with a plurality of second acting sheets 221, such that the plurality of first acting sheets 121 and the plurality of second acting sheets 221 are configured in a staggered manner. Specifically, when the first rod 120 is aligned with the second rod 220, the plurality of first acting pieces 121 and the plurality of second acting pieces 221 are arranged in a staggered manner (i.e., they are arranged in a non-parallel manner), as shown in fig. 2B, and a portion of the second acting pieces 221 are exposed out of the first opening 110, so that when the second rod 220 rotates relative to the second rod 222, the plurality of second acting pieces 221 can be used to push the material in the second containing groove 21 toward the second opening 210, so that the material leaves the second containing groove 21 from the second opening 210.

In addition, the second active piece 221 is a rectangular surface piece, and the rectangular surface can be a flat surface or an inclined surface.

In addition, the second link 220 extends forward relative to the second action pieces 221 on two opposite sides (left and right sections) of the second link 222, as shown in fig. 3B. For example, the second action pieces 221 each project the shaft of the second lever member 220 in a clockwise direction toward the wall structure 21 c.

The power device 3 includes a power source 30 such as a motor and a transmission rod 31 for driving the power source 30, so that the transmission rod 31 drives the first stirring element 12 and the second stirring element 22.

In this embodiment, the transmission rod 31 is coupled to the first shaft 122 and the second shaft 222 to rotate the first shaft 122 and the second shaft 222, so that the first rod 120 can rotate relative to the first shaft 122, and the second rod 220 can rotate relative to the second shaft 222. For example, the transmission rod 31 has a first end 31a and a second end 31b opposite to each other, and the first end 31a is engaged with the power source 30, and the second end 31b is disposed on the plate body 21a of the second receiving groove 21. Specifically, a shaft hole 211 (as shown in fig. 2A) is formed in the middle of the plate body 21a of the second receiving groove 21 for the transmission rod 31 to be inserted, and the second shaft element 222 is disposed above the shaft hole 211.

In addition, since the transmission rod 31 passes through the first opening 110, the aperture of the first opening 110 needs to be larger than the width of the transmission rod 31, so that the material in the first accommodating cavity 11 can leave the first accommodating cavity 11 from the first opening 110.

Therefore, when the fermentation apparatus 1a is used, the power device 3 is first activated to rotate the transmission rod 31 in the clockwise direction W to actuate the first stirring component 12 and the second stirring component 22, at this time, the first shaft 122, the first rod 120, the second shaft 222 and the second rod 220 also rotate in the clockwise direction W, so that the material in the first accommodating groove 11 is pushed by the first action pieces 121 to be stirred, and the first action pieces 121 push the material in the first accommodating groove 11 toward the first opening 110 (as shown in the arrow direction X1 in fig. 2C), and the material falls from the first opening 110 into the second accommodating groove 21 (as shown in the arrow direction Z1 in fig. 2C). As will be understood, since the plurality of first acting pieces 121 are disposed obliquely toward the front, the moving path L1 of the material is in a spiral shape from the outside to the inside (as shown in fig. 4A).

Then, the material falling into the second receiving groove 21 is pushed by the second acting pieces 221 to generate stirring, and the second acting pieces 221 push the material in the second receiving groove 21 toward the second opening 210 (as shown by the arrow direction X2 in fig. 2C), and make the material fall out from the second opening 210 (as shown by the arrow direction Z2 in fig. 2C). It should be understood that, since the plurality of second acting pieces 221 are disposed obliquely toward the rear, the moving path L2 of the material is in a spiral shape from the inside to the outside (as shown in fig. 4B).

In other words, the material is displaced along the displacement direction from the outside to the inside (the arrow direction X1 shown in fig. 2C), the displacement direction from the top to the bottom (the arrow direction Z1 shown in fig. 2C), and the displacement direction from the inside to the outside (the arrow direction X2 shown in fig. 2C) of the first acting device 1, respectively, during the fermentation operation, and the microorganism decomposes the material at the same time, so that the user can collect the target object (or decomposed material) such as fertilizer outside the second opening 210. Therefore, the position of the first opening 110 and the position of the second opening 210 are not aligned, that is, the vertical projection range of the first opening 110 and the vertical projection range of the second opening 210 are not partially overlapped or completely overlapped.

In another embodiment, the first acting device 1 and the second acting device 2 can be configured with a temperature sensor (not shown) and/or a humidity sensor (not shown) to monitor the temperature in the first containing groove 11 and the second containing groove 21 by using the temperature sensor and/or the humidity sensor, so as to know whether the fermentation equipment 1a is kept in an environment suitable for the growth of microorganisms, thereby facilitating the decomposition of the material.

In addition, since the main decomposition process occurs in the lower layer action device (second action device), when the first action device 1 (first containing groove 11) covers most of the area of the second action device 2 (second containing groove 21), the odor generated during the decomposition or fermentation process of the material can be prevented from being scattered and overflowed greatly. Further, a cover (not shown) having an exhaust hole may be covered on the top-most slot 11a of the fermentation apparatus 1a to guide the odor gas to the deodorizing means (not shown) through the exhaust hole.

Therefore, when the fermentation apparatus 1a is used, the power device 3 is first activated to make the transmission rod 31 actuate the first stirring component 12 and the second stirring component 22, at this time, the material in the first accommodating groove 11 is pushed by the first action pieces 121 to generate stirring, and the first action pieces 121 push the material in the first accommodating groove 11 toward the first opening 110, and the material falls from the first opening 110 into the second accommodating groove 21. Then, the material falling into the second containing groove 21 is pushed by the second action pieces 221 to generate stirring, and the second action pieces 221 push the material in the second containing groove 21 toward the second opening 210, so that the material falls out from the second opening 210.

Further, a storage device 4 may be disposed below the plate body 21a of the second receiving groove 21, as shown in fig. 2A, and may include a collecting groove 42 and a guiding structure 41 communicating the second opening 210 and the collecting groove 42. For example, the guiding structure 41 is funnel-shaped, so that the material falling from the second opening 210 can enter the collecting tank 42 along the guiding structure 41.

Alternatively, a through-hole port 43 may be formed at the guide structure 41. Specifically, the through hole port 43 communicates with the guide structure 41 and serves as an air hole for controlling the temperature of the fermentation apparatus 1 b. For example, gases with different temperatures/humidities can be introduced through the through hole port 43 to control the temperature, so that the fermentation apparatus 1b is maintained in an environment suitable for the growth of microorganisms to facilitate the decomposition of the material.

In addition, as shown in fig. 3A, each of the first acting pieces 121 is inclined relative to the axis P1 of the first rod 120 to form a first included angle θ, θ 1, θ 2, θ 3(0 ° < θ, θ 1, θ 2, θ 3<180 °), and the angles of the first included angles θ, θ 1, θ 2, θ 3 may be the same or different. For example, the first included angles θ, θ 1, θ 2, θ 3 are acute angles (between 45 ° and 60 °), and the degrees of the first included angles θ, θ 1, θ 2, θ 3 are different from each other, and the angles of the first included angles θ, θ 1, θ 2, θ 3 gradually increase from the first shaft 122 (or the first opening 110) to the wall structure 11c of the first accommodating cavity 11 (i.e., gradually decrease from outside to inside in a manner of θ > θ 1> θ 2> θ 3), so that the first stirring assembly 12 has a higher propelling speed for the material close to the first opening 110 than for the material far from the first opening 110 (close to the wall structure 11c), so as to gradually accelerate the material to be pushed out of the first opening 110.

In addition, as shown in fig. 3B, each of the second acting pieces 221 is inclined with respect to the axis P2 of the second rod 220 to form a second included angle α, α 1, α 2, α 3, α 4(0 ° < α, α 1, α 2, α 3, α 4<180 °), and the angles of the second included angles α, α 1, α 2, α 3, α 4 may be the same or different. For example, the second included angles α, α 1, α 2, α 3, α 4 are obtuse angles (the degrees of which are about 120 ° to 150 °), and the degrees of the second included angles α, α 1, α 2, α 3, α 4 are different from each other, and the angles of the second included angles α, α 1, α 2, α 3, α 4 are gradually decreased from the second shaft element 222 to the wall structure 21c of the second accommodating cavity 21 (i.e. gradually increased from outside to inside in a manner of α < α 1 < α 2 < α 3< α 4), so that the advancing speed of the second stirring assembly 22 for the material close to the second shaft element 220 (far away from the second opening 210) is greater than the advancing speed of the material far away from the second shaft element 220 (near the second opening 210), so as to gradually push the material out of the second opening 210 in a decelerating manner.

Therefore, the fermentation equipment 1a is provided with the action pieces with different inclination angles, so that when the rod piece rotates for a fixed angle to drive each action piece, the amount of the materials pushed by each action piece to the corresponding opening direction is the same or similar. In detail, as shown in fig. 3A, since the inclination angles of the first piece 121 on the first rod 120 are different, when the first rod 120 rotates, the amount (or volume) of the material pushed by the first action piece 121 close to the first opening 110 and the first action piece 121 close to the wall structure 21c toward the first opening 110 are the same or similar, so as to prevent the material from accumulating at the first opening 110, and to enable the microorganism to decompose the material in the same area uniformly; in other words, if the inclination angles of the action pieces are the same, when the rod rotates one turn, the moving volume of the material located in the outer ring is larger, and the moving volume of the material located in the inner ring is smaller, so that the material is accumulated in the inner ring. For example, the moving path L1 of the material at each position of the first container 11 is spiral (as shown in fig. 4A), and the moving path L2 of the material at each position of the second container 21 is spiral (as shown in fig. 4B).

FIG. 5 is a schematic perspective view of another embodiment of the fermentation apparatus 1b of the present invention. The difference between this embodiment and the above embodiments is that the action device is added, and other structures are substantially the same, so the same parts are not described in detail below.

As shown in FIG. 5, the fermentation apparatus 1b comprises a plurality of first action devices 1 and a plurality of second action devices 2, and each of the first action devices 1 and each of the second action devices 2 are sequentially stacked in an interlaced manner.

In the present embodiment, each of the acting devices covers the

notches

11b and 21b of the acting device below the acting device with the

plate bodies

11a and 21a, and the first acting device 1 is arranged at the uppermost layer for pouring the required material. In another embodiment, the uppermost layer can be the second acting device 2, and is not particularly limited. It should be understood that the lowest layer can be the second acting device 2 or the first acting device 1 according to the requirement, and is not particularly limited.

In addition, the transmission rod 31 is increased as required to connect each of the first stirring elements 12 and the second stirring elements 22.

In addition, when the fermentation apparatus 1B is activated, it drives the moving path of the material therein to move spirally on the horizontal plane (i.e. the bottom of the containing groove) (as shown in fig. 4A and 4B), and move in the longitudinal direction (i.e. the up-down direction of fig. 5) (as shown in fig. 2C) in an "S-shape" manner, so that the material moves downwards by repeating inward and outward movements, i.e. the material moves according to the sequence of outer, inner, lower, inner and outer positions, in the case that the first acting device 1 and the second acting device 2 are stacked alternately.

Therefore, the fermentation equipment 1b of the present invention can be provided with the number of the first acting device 1 and the second acting device 2 according to the requirement, so that the fermentation volume can be increased in the same fermentation place without increasing the floor area, so as to produce the required fertilizer amount, and further achieve the purpose of improving the productivity.

On the other hand, when the user uses the material requiring a longer time course for decomposition and fermentation, the number of the first acting device 1 and the second acting device 2 can be increased to increase the displacement path and time required for the material to fall to the storage device 4 (or fall out of the second opening 220 or the first opening 110 of the lowest layer), so as to increase the time course for decomposition, thereby achieving the purpose of effectively decomposing the material.

The above embodiments are merely illustrative, and not restrictive, of the invention. Modifications and variations can be made to the above-described embodiments by those of ordinary skill in the art without departing from the spirit and scope of the present invention. Therefore, the scope of the invention is defined by the appended claims, and is intended to be covered by the following claims unless they do not affect the effect or the purpose of the invention.
