Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically to an ecological cycle device for breeding and planting. Background Technology

[0002] Waste generated by the livestock industry (such as livestock and poultry manure and straw) is transformed into fertilizer for the crop industry, and the products of the crop industry (such as crop straw) serve as feed for the livestock industry, forming an ecological closed loop, thereby reducing external inputs and pollution emissions.

[0003] Traditional methods of waste disposal typically involve drying and crushing waste to produce fertilizer. Drying can inhibit pathogens, while crushing can accelerate fertilizer decomposition and allow for better absorption by the soil. However, some nutrients evaporate with the moisture during the drying process, resulting in low resource utilization.

[0004] Currently, the most common way to treat waste is to ferment it. By putting the waste into a fermentation tank, the waste fermentation will produce solid and liquid products. Both solid and liquid products can be used as plant fertilizer, thereby reducing nutrient loss.

[0005] The fermentation cycles of solid and liquid products are different. In the existing technology, solid products are soaked in liquid products for fermentation, making it difficult to control the fermentation cycle separately. This results in incomplete nutrient conversion, and some straw in the waste is too long to be completely decomposed. Utility Model Content

[0006] To address this, the present invention provides an ecological cycle device for breeding and planting, which solves the technical problems in the prior art where solid products are soaked in liquid products for fermentation, making it difficult to control the fermentation cycle separately, resulting in incomplete nutrient conversion, and some straw in the waste is too long to be completely decomposed.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: An ecological cycle device for breeding and planting, comprising: Fermentation tank with a hinged, sealing lid at the top; A perforated plate is disposed inside the fermenter. The perforated plate is parallel to the bottom of the fermenter and its periphery is tightly attached to the inner wall of the fermenter. The perforated plate divides the fermenter from top to bottom into a solid waste fermentation tank and a liquid waste fermentation tank. A number of perforation holes are evenly provided on the perforated plate. A feeding pool is provided on the outer wall of the solid waste fermentation tank. A screw conveyor is provided inside the feeding pool. When the screw conveyor rotates, it can transport the material in the feeding pool to the solid waste fermentation tank. A water pump, connected to the liquid waste fermentation tank, is used to extract the liquid from the liquid waste fermentation tank.

[0008] Furthermore, the water pump is specifically a double-acting pump; The water pump has an inlet pipe connected to its inlet, and the end of the inlet pipe away from the water pump is connected to the liquid waste fermentation tank. The water pump also has a water outlet pipe connected to its outlet.

[0009] Furthermore, a first water valve is provided on the liquid inlet pipe, and a spray pipe is connected to the liquid inlet pipe, with the spray pipe connected above the first water valve. A second water valve is installed on the spray pipe, and the end of the spray pipe away from the liquid inlet pipe extends into the interior of the fermenter.

[0010] Furthermore, a spray head is installed at the bottom of the perforated plate, and the end of the spray pipe away from the liquid inlet pipe is connected to the spray head.

[0011] Furthermore, a vent pipe is connected to the sealing cover, and a cover plate is provided on the feeding pool.

[0012] Compared with the prior art, this utility model has the following advantages: This invention utilizes a perforated plate within the fermentation tank to divide it into a solid waste fermentation tank and a liquid waste fermentation tank. Waste is conveyed to the fermentation tank via a screw conveyor and falls directly onto the perforated plate (i.e., the solid waste fermentation tank). Liquid products generated during fermentation flow through perforations into the liquid waste fermentation tank, while solid products continue to ferment within the solid waste fermentation tank. This achieves solid-liquid separation fermentation, facilitating independent control of the fermentation cycles for both solid and liquid products. After fermentation, the solid and liquid products are used for fertilization and irrigation, respectively, achieving a recycling effect. Furthermore, as the screw conveyor rotates and pushes the waste into the fermentation tank, the straw is sheared by the blades on the screw conveyor, forming shorter straw segments, thus ensuring thorough decomposition as much as possible.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides an ecological cycle device for breeding and planting, which includes: Fermentation tank 1, with a sealing cover 2 hinged to the top; A perforated plate 3 is installed inside the fermentation tank 1. The perforated plate 3 is parallel to the bottom of the fermentation tank 1 and its periphery is tightly attached to the inner wall of the fermentation tank 1. The perforated plate 3 divides the fermentation tank 1 from top to bottom into a solid waste fermentation tank 101 and a liquid waste fermentation tank 102. Several perforation holes 7 are evenly arranged on the perforated plate 3. The feeding pool 4 is located on the outer wall of the solid waste fermentation tank 101. The feeding pool 4 is equipped with a screw conveyor 5. When the screw conveyor 5 is rotating, it can transport the material in the feeding pool 4 to the solid waste fermentation tank 101. Water pump 6 is connected to liquid waste fermentation tank 102 and is used to extract liquid from the liquid waste fermentation tank 102.

[0018] This invention utilizes a perforated plate 3 within a fermentation tank 1 to divide the fermentation tank into a solid waste fermentation tank 101 and a liquid waste fermentation tank 102. Waste is transported to the fermentation tank 1 via a screw conveyor 5 and falls directly onto the perforated plate 3 (i.e., into the solid waste fermentation tank 101). During fermentation, the liquid products generated fall into the liquid waste fermentation tank 101 through the seepage holes 7, while the solid products continue to ferment within the solid waste fermentation tank 101. This achieves solid-liquid separation fermentation, facilitating independent control of the fermentation cycles of the solid and liquid products. After fermentation, the solid and liquid products are used for fertilization and irrigation, respectively, achieving a recycling effect. Furthermore, as the screw conveyor 5 rotates and pushes the waste into the fermentation tank 1, the straw is sheared by the blades on the screw conveyor 5 into shorter straw segments, thus decomposing it as thoroughly as possible.

[0019] After the waste fermentation is completed, the sealed cover 2 is opened and the solid products are manually shoveled out for use as plant fertilizer. The liquid products are pumped out by the water pump 6 for plant irrigation. Generally, the proportion of liquid products is higher than that of solid products. In order to leave enough space for liquid products, the height of the liquid waste fermentation tank 102 is greater than that of the solid waste fermentation tank 101. During the rotation of the screw conveyor 5, the pressure exerted by the blades on the screw conveyor 5 against the inner wall of the feeding pool 4, as well as the pushing force of the screw conveyor 5, can shear and tear the straw, causing some of the straw to become shorter straw segments.

[0020] To facilitate opening the sealing cover 2, a handle 16 is provided on the sealing cover 2, which facilitates applying force to the sealing cover 2.

[0021] like Figure 2 As shown, after the waste enters the fermentation tank 1, it falls directly onto the perforated plate 3. Small solid particles in the waste may fall to the bottom of the fermentation tank 1 through the perforated plate 3. After long-term use, the small solid particles will accumulate and clump together, which can easily clog the inlet of the water pump 6 when extracting liquid products. In order to prevent the water pump 6 from clogging, this utility model is designed to clean the liquid waste fermentation tank 102 by water impact. Specifically, the water pump 6 is a double-acting pump. The inlet of the water pump 6 is connected to the liquid inlet pipe 8, and the end of the liquid inlet pipe 8 away from the water pump 6 is connected to the liquid waste fermentation tank 102. The outlet of the water pump 6 is connected to the water pipe 9. A first water valve 10 is provided on the liquid inlet pipe 8, and a spray pipe 11 is connected to the liquid inlet pipe 8. The connection position of the spray pipe 11 is located above the first water valve 10. A second water valve 12 is installed on the spray pipe 11, and the end of the spray pipe 11 away from the liquid inlet pipe 8 extends into the interior of the fermenter 1; A spray head 13 is installed at the bottom of the perforated plate 3, and the end of the spray pipe 11 away from the liquid inlet pipe 8 is connected to the spray head 13; When the water pump 6 is in positive pumping mode, the first water valve 10 is opened and the second water valve 12 is closed, and the liquid product in the fermenter 1 enters the water pipe 9 through the liquid inlet pipe 8; When it is necessary to clean the waste fermentation tank 102, the water pump 6 is controlled to reverse pumping mode, and the first water valve 10 is closed and the second water valve 12 is opened. The external clean water enters the spray pipe 11 through the water pipe 9, and then is sprayed into the fermentation tank 1 through the spray head 13. The high pressure water force generated after the clean water is sprayed out through the spray head 13 breaks up the small solid particles that have accumulated inside the fermentation tank 1. Then the water pump 6 is controlled to forward pumping mode, the first water valve 10 is opened and the second water valve 12 is closed. The broken small solid particles are drawn out with the cleaning water through the liquid inlet pipe 8 and the water pipe 9, thereby avoiding the water pump 6 from getting blocked as much as possible. The connection point of the spray pipe 11 on the liquid inlet pipe 8 is located above the first water valve 10. When cleaning the fermentation tank 1, the first water valve 10 is closed so that clean water can enter the spray pipe 11 through the water pipe 9. The water holes on the spray head 13 are small. When the water pump 6 is in the positive pumping mode, the second water valve 12 is closed to prevent liquid products from being drawn out through the spray pipe 11, thereby preventing small particles of solid from clogging the spray head 13.

[0022] During the fermentation process, the waste will produce a large amount of gas. In order to balance the gas pressure inside and outside the fermentation tank 1, a vent pipe 14 is connected to the sealing cover 2. The gas inside the fermentation tank 1 is discharged through the vent pipe 14. Since the fermentation of waste needs to maintain an anaerobic environment, the fermentation tank 1 can be ventilated intermittently. During the period when ventilation is not required, the vent pipe 14 is sealed with cement.

[0023] To prevent rainwater from entering the fermentation tank 1 through the feeding pool 4, a cover plate 15 is installed on the feeding pool 4. When waste needs to be added, the cover plate 15 is opened, and when no waste needs to be added, the cover plate 15 is closed.

[0024] This embodiment also generally includes a drive device for driving the screw conveyor 5 to rotate. The drive device can be a device in the prior art that can provide rotational driving force, such as a drive motor.

[0025] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
