Description

Technical Field

[0001] The invention belongs to the field of organic waste treatment, and more specifically, relates to an animal and poultry excrement organic fertilizer fermentation tower and a control method. Background Art

[0002] In recent years, the livestock and poultry farming industry has developed rapidly. For farmers of a certain scale, the harmless treatment and rational utilization of livestock and poultry manure are issues that must be faced. Converting livestock and poultry manure into organic fertilizer is one of the conventional ways of harmless treatment and rational utilization.

[0003] When fermenting livestock and poultry manure, an organic fertilizer fermentation device is usually used. It is mainly used to seal, store and ferment manure. The manure is fermented into organic fertilizer through static fermentation. The overall fermentation cycle is short and no secondary pollution is generated during fermentation. The fermented organic fertilizer has a high organic matter content, and the beneficial bacteria in it can better fix nitrogen, dissolve phosphorus and potassium.

[0004] At present, the existing organic fertilizer fermentation device for livestock and poultry manure usually includes a stirring system and an oxygen supply system, which cooperate with each other to realize manure fermentation. Among them, the traditional stirring system generally adopts a spiral stirring device, and the oxygen supply system generally adopts an oxygen supply machine or a blower and other equipment to directly transport oxygen to the fermentation device, and the manure in the fermentation tower is loosened and the manure and oxygen are fully integrated through the spiral stirring action. However, from the current actual use effect, for large-capacity fermentation devices, such a stirring and oxygenating structure cannot ensure uniform and sufficient oxygenation in the fermentation device, and the fermentation effect is not good, which will cause serious agglomeration of the final manure; in addition, the existing fermentation device directly discharges the material after the fermentation cycle ends, so that the block manure produced during the fermentation process is also discharged, and the quality of the discharged manure is not high.

[0005] On the other hand, the existing control method for organic fertilizer fermentation device is usually based on the maximum fermentation capacity of the fermentation device. The fermentation process of feces in the fermentation device is all the same. After a fermentation cycle is completed, all the materials are discharged uniformly, and then fresh feces are added for the next fermentation cycle. This will cause the time of a single fermentation cycle and the discharge time to be too long, and the time for adding materials in the middle is also longer, which affects the continuity of the fermentation work and the work efficiency is low.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figure 1 to Figure 2The livestock and poultry manure organic fertilizer fermentation tower shown comprises a fermentation box 1, which is in a rectangular box structure. A manure inlet 2 is arranged at the upper part of the fermentation box 1, and a manure outlet 3 is arranged at the lower part of the fermentation box.

[0041] In this embodiment, the feces inlet 2 is opened on the side wall of the fermentation box 1, and a horizontal feces conveying channel 15 is installed at the feces inlet 2. The feces conveying channel 15 adopts a conveyor belt structure, and both sides of the feces conveying channel 15 are slidably connected in the fermentation box 1, that is, the feces conveying channel 15 can move back and forth in the horizontal direction, thereby adjusting the landing point of feces in the fermentation box 1 to avoid that all feces fall into the fermentation box 1 from the same position and form excessive accumulation, causing space waste; on the other hand, the end of the feces conveying channel 15 located in the fermentation box 1 is set to be open (not shown in the figure), and the open setting is to increase the scattering area of ​​​​feces when entering the fermentation box 1, thereby improving the feeding efficiency.

[0042] The above-mentioned structural design of the feces conveying channel 15 is based on the consideration of large-volume fermentation. If the volume of the fermentation box 1 is small, its cross-section in the horizontal direction is relatively small, and the feces inlet 2 can be arbitrarily set at any position on the upper part of the fermentation box 1, such as the side wall or the top, and even if the feces conveying channel 15 is directly fixedly connected to the feces inlet 2 and no open end is set, it is not easy to cause feces accumulation; however, if the volume of the fermentation box 1 is large, its cross-section in the horizontal direction will certainly be larger. If a conventional setting is adopted, the scattering area of ​​the end of the feces conveying channel 15 in the fermentation box 1 is small, and it cannot fully cover the entire horizontal cross-sectional area of ​​the fermentation box 1, which will form feces accumulation and cause space waste. Therefore, for this reason, the feces inlet 2 is set on the side wall of the fermentation box 1, and a horizontally movable feces conveying channel 15 is installed, and an open end is set at the same time to increase the scattering area of ​​​​feces, thereby improving the accumulation of feces.

[0043] In this embodiment, the manure outlet 3 is arranged directly below the fermentation box 1 and is wedge-shaped. This structural design is to facilitate centralized collection of manure when discharging. It should be understood that a manure collection pool can be installed at the wedge-shaped outlet end of the manure outlet 3 to centrally collect the discharged manure and facilitate subsequent bagging of the manure.

[0044] Furthermore, if Figure 3 and Figure 4As shown, multiple layers of oxygen supply plates are arranged in parallel in the fermentation box 1, and an oxygen supply pipe 4 is arranged above each layer of the oxygen supply plates. The oxygen supply pipe 4 is installed close to the oxygen supply plate, and one end of the oxygen supply pipe 4 passes through the fermentation box 1 and is connected to the oxygen supply equipment arranged outside the fermentation box 1. A plurality of air outlets are opened on the oxygen supply pipe 4. In this embodiment, the oxygen supply equipment is an existing equipment such as an oxygen supply machine, an air pump or a blower, which is used to transport oxygen into the fermentation box 1 through the oxygen supply pipe 4.

[0045] The oxygen supply plate includes a primary oxygen supply plate 5 arranged at the upper part of the fermentation box 1 and a secondary oxygen supply plate 6 arranged at the lower part of the fermentation box 1. In the present embodiment, the primary oxygen supply plate 5 and the secondary oxygen supply plate 6 are both set as one. In more embodiments, the number of the primary oxygen supply plate 5 and the secondary oxygen supply plate 6 can be increased accordingly according to the capacity of the fermentation box.

[0046] More specifically, if Figures 3 to 6 As shown, the primary oxygen supply plate 5 includes a plurality of criss-cross connected baffles 51, both ends of the plurality of baffles 51 are fixedly connected to the inner wall of the fermentation box 1, and the intervals between the plurality of baffles 51 form leaky gaps; the secondary oxygen supply plate 6 includes a plurality of horizontal stirring rods 61 connected in a criss-cross manner, and a vertical stirring rod 7 is also installed at the staggered connection of the horizontal stirring rods 61, and the secondary oxygen supply plate 6 is also connected to a first driving member 8, which is installed on the outside of the fermentation box 1 and can drive the secondary oxygen supply plate 6 to perform reciprocating horizontal motion, and in order to ensure that the secondary oxygen supply plate 6 can move stably in the fermentation box 1, both ends of the vertical stirring rod 7 perpendicular to the driving direction of the first driving member 8 are slidably connected to the inner wall of the fermentation box 1.

[0047] In addition, in order to ensure the working strength of the primary oxygen supply plate 5 and the secondary oxygen supply plate 6, the above-mentioned blocking rod 51, the horizontal stirring rod 61, and the vertical stirring rod 7 are all made of angle irons, and their connections are all fixed by welding.

[0048] The above-mentioned primary oxygen supply plate 5 and secondary oxygen supply plate 6 both adopt a grid plate structure, which can play a certain buffering and retention role for the feces in the fermentation box 1, so that the feces in this area can fully receive the oxygen from the oxygen supply pipe 4, ensuring that the oxygen supply is in place to improve the fermentation effect; at the same time, the secondary oxygen supply plate 6 located at the lower part of the fermentation box 4 is slidably connected in the fermentation box 1 and is equipped with a first driving member 8 so that it can reciprocate horizontally in the fermentation box 1, thereby relying on the vertical stirring rod 7 thereon to stir the feces horizontally, and with the assistance of the oxygen supply from the upper oxygen supply pipe 4 to achieve full contact between the feces and oxygen, which can speed up the fermentation process and loosen the feces to avoid agglomeration during the fermentation process.

[0049] Furthermore, a discharge sieve plate 9 is further provided below the oxygen supply plate, and the discharge sieve plate 9 comprises a fixed sieve plate 91 at a lower layer and a movable sieve plate 92 at an upper layer. As the name implies, the fixed sieve plate 91 is fixedly mounted on the inner wall of the fermentation box 1, and the movable sieve plate 92 is slidably mounted on the inner wall of the fermentation box 1. The fixed sieve plate 91 and the movable sieve plate 92 are both provided with a plurality of discharge slits 93 parallel to each other, and a second driving member 10 is connected to any side of the movable sieve plate 92 parallel to the discharge slit 93. The second driving member 10 is installed on the outside of the fermentation box 1 and can drive the movable screen plate 92 to perform reciprocating horizontal motion, and when the movable screen plate 92 performs reciprocating horizontal motion, the discharge slits 93 on the fixed screen plate 91 and the movable screen plate 92 can correspond to each other and be connected up and down, thereby forming a discharge channel for manure to fall to the manure outlet; it should be noted that when the second driving member 10 is not started, the discharge slits 93 on the fixed screen plate 91 and the movable screen plate 92 are in a staggered state, that is, the discharge channel is in a closed state.

[0050] like Figure 7 and Figure 8 As shown, in this embodiment, the fixed sieve plate 91 and the movable sieve plate 92 are both composed of a plurality of angle irons arranged in parallel, the discharge seam 93 is formed by the right-angled sides of two angle irons arranged at intervals, the two ends of the angle iron in the fixed sieve plate 91 are fixedly mounted on the inner wall of the fermentation box 1, the movable sieve plate 92 rests on the upper surface of the fixed sieve plate 91, and the two ends of all the angle irons in the movable sieve plate 92 are connected as a whole by a cross bar.

[0051] In this embodiment, the above-mentioned first driving member 8 and the second driving member 10 both adopt hydraulically driven cylinders, which realize the reciprocating horizontal movement of the secondary oxygen supply plate 6 and the movable screen plate 92 by extending and retracting the piston rod of the cylinder. Of course, in more embodiments, a rotating motor driving a screw rod can also be used to achieve it; the first driving member 8 and the second driving member 10 are both fixedly mounted on the outer wall of the same side of the fermentation box 1, that is, the movement direction of the secondary oxygen supply plate 6 and the movable screen plate 92 are consistent.

[0052] The specific installation structure of the first driving member 8 and the second driving member 10 is: the cylinder body thereof is fixedly mounted on the outer wall of the fermentation box 1, the cylinder piston rod thereof passes through the fermentation box 1 and is connected to the secondary oxygen supply plate 6 or the movable screen plate 92. It can be foreseen that a sliding bearing and a corresponding sealing structure are also provided between the cylinder piston rod and the fermentation box 1, and the piston rod part located in the fermentation box 1 is also wrapped with a flexible protective cover.

[0053] It also includes a controller, and the oxygen supply equipment, the first driving member 8, and the second driving member 10 are electrically connected to the controller. The controller is used to control the start and stop of the oxygen supply equipment, the first driving member 8, and the second driving member 10. In this embodiment, the controller adopts a PLC electrical controller.

[0054] The overall workflow is described below in conjunction with the technical solution in this embodiment:

[0055] During the first fermentation, the feces are transported from the feces inlet 2 into the fermentation box 1 through the feces loosening channel 15. After the feces added to the fermentation box 1 reaches the maximum feces capacity, the oxygen supply device and the first driving member 8 are started, and the oxygen supply device starts to supply oxygen to the fermentation box 1. The first driving member 8 drives the secondary oxygen supply plate 6 and drives the vertical stirring rod 7 thereon to start horizontal reciprocating motion. Under the horizontal stirring action, the feces are loosened and scattered, and better contact between the feces and oxygen is promoted. After a period of intermittent oxygen supply and stirring fermentation, the oxygen supply and stirring are stopped, and the second driving member is started. 10, the second driving member 10 drives the movable sieve plate 92 in the discharging sieve plate 9 to start horizontal reciprocating motion. When the movable sieve plate 92 moves to the point where its discharging slit 93 corresponds to the discharging slit 93 on the fixed sieve plate 91, a discharging channel is formed, so that the manure particles in the fermentation box 1 that meet the specifications of the discharging slit 93 leak out through the discharging channel, while the manure particles with larger particles remain in the fermentation box 1 for the next discharging cycle; after the single discharging amount of the fermentation box 1 reaches the set value, the second driving member 10 is turned off, the discharging is stopped, and fresh manure equal to the single discharging amount is added to repeat the above fermentation cycle.

The plurality of oxygen supply pipes 4 are laid flat on top of the oxygen supply boards in a covering manner, and all the oxygen supply pipes 4 above the same layer of oxygen supply boards are connected in parallel.

[0058] In this embodiment, two oxygen supply pipes 4 are provided above the primary oxygen supply plate 5, and three oxygen supply pipes 4 are provided above the secondary oxygen supply plate 6. Arranging multiple parallel oxygen supply pipes 4 in the same layer can improve the oxygen supply efficiency and uniformity in the corresponding area.
