Description

Technical Field

[0001] This utility model relates to the field of fermentation treatment equipment technology, and in particular to fermentation treatment equipment for livestock and poultry waste. Background Technology

[0002] Fermentation technology for livestock and poultry manure is an effective treatment method that utilizes the metabolic activities of microorganisms to decompose the organic matter in livestock and poultry manure into water, carbon dioxide, and stable organic fertilizer. During this process, harmful substances are effectively reduced or even eliminated, while the nutrients in the manure are retained, achieving both harmless treatment and resource utilization.

[0003] However, the existing main method for treating livestock and poultry manure is composting, which involves directly mixing manure with sewage and adding fermentation agents for fermentation without solid-liquid separation. This leads to a significant increase in the amount of fermentation agents used, and the uneven mixing of solid and liquid waste makes it difficult to ferment fully, thus reducing the overall fermentation efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fermentation treatment device for livestock and poultry waste. Through the combination of a solid-liquid separation filter plate and an extrusion assembly, the device can efficiently separate the solid and liquid components in livestock and poultry waste, which helps the subsequent fermentation process proceed smoothly and reduces the difficulty and cost of wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A filter plate is fixedly installed inside the solid-liquid separation chamber. A wastewater outlet is provided on the side wall of the solid-liquid separation chamber. A compression assembly for compressing waste is provided inside the solid-liquid separation chamber. A second motor is fixedly installed at the upper end of the shell. The output shaft of the second motor extends into the fermentation chamber and is fixedly fitted with a stirring paddle. An outlet is provided at the lower end of the fermentation chamber. An opening and closing assembly for opening and closing the outlet is provided inside the outlet.

[0007] Preferably, the closure assembly includes a second electric push rod fixedly mounted on the upper end of the housing, the telescopic end of the second electric push rod extending into the housing and fixedly mounted with a baffle.

[0008] Preferably, the lower end of the baffle is provided with a protrusion, and the upper end of the lower partition is provided with a groove that matches the protrusion.

[0009] Preferably, the extrusion assembly includes a first electric push rod fixedly mounted on the side wall of the housing, and an extrusion plate is fixedly mounted on the telescopic end of the first electric push rod.

[0010] Preferably, the opening and closing assembly includes a receiving groove formed on the inner side of the discharge port, an opening and closing plate is slidably connected inside the receiving groove, a first motor is fixedly installed on the side wall of the housing, a screw is fixedly installed at the end of the output shaft of the first motor, and the screw is threadedly connected to the opening and closing plate.

[0011] Preferably, the bottom of the fermentation chamber consists of two symmetrically arranged inclined surfaces, and the discharge port is located between the two inclined surfaces.

[0012] This utility model has the following beneficial effects:

[0013] Through its built-in filter plates and extrusion components, the equipment can efficiently separate the solid and liquid components from livestock and poultry waste.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be arbitrarily changed by the livestock and poultry waste fermentation treatment equipment, and the layout of the components may also be more complex.

[0021] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0022] Reference Figures 1-3 The livestock and poultry waste fermentation treatment equipment includes a shell 1. Inside the shell 1, a solid-liquid separation chamber and a fermentation chamber 15 are formed by a lower partition 13 and an upper partition 11. A closing assembly is provided between the lower partition 13 and the upper partition 11. The closing assembly includes a second electric push rod 6 fixedly installed on the upper end of the shell 1. The telescopic end of the second electric push rod 6 extends into the shell 1 and is fixedly installed with a baffle 12. The lower end of the baffle 12 has a protrusion, and the upper end of the lower partition 13 has a groove adapted to the protrusion. Therefore, the baffle 12 can tightly fit or separate from the lower partition 13, realizing the connection or isolation between the solid-liquid separation chamber and the fermentation chamber 15. A feed inlet 5 is provided at the upper end of the solid-liquid separation chamber. A filter plate 9 is fixedly installed inside the solid-liquid separation chamber. A wastewater discharge outlet 3 is provided on the side wall of the solid-liquid separation chamber. A useful... The extrusion assembly for extruding waste includes a first electric push rod 4 fixedly installed on the side wall of the housing 1, and an extrusion plate 10 fixedly installed at the telescopic end of the first electric push rod 4; a second motor 7 is fixedly installed at the upper end of the housing 1, and the output shaft of the second motor 7 extends into the fermentation chamber 15 and is fixedly installed with a stirring paddle 14; a discharge port is opened at the lower end of the fermentation chamber 15, and the bottom of the fermentation chamber 15 has two symmetrically arranged inclined surfaces, with the discharge port located between the two inclined surfaces; an opening and closing assembly for opening and closing the discharge port is provided inside the discharge port, and the opening and closing assembly includes a receiving groove opened on the inner side of the discharge port, with an opening and closing plate 8 slidably connected inside the receiving groove; a first motor 2 is fixedly installed on the side wall of the housing 1, and a screw 16 is fixedly installed at the end of the output shaft of the first motor 2, with the screw 16 threadedly connected to the opening and closing plate 8.

[0023] In use, livestock and poultry waste enters the solid-liquid separation chamber through the feed inlet 5. Inside the chamber, the waste is filtered by the filter plate 9, achieving solid-liquid separation. The liquid portion is discharged through the wastewater outlet 3, while the solid portion remains inside the solid-liquid separation chamber.

[0024] To improve the efficiency of solid-liquid separation, the extrusion assembly begins operation. The first electric push rod 4 drives the extrusion plate 10 to move towards the filter plate 9, extruding the waste and further squeezing out the liquid.

[0025] After solid-liquid separation is completed, the solid waste needs to be transferred to the fermentation chamber 15. At this time, the second electric push rod 6 is activated, and its telescopic end drives the baffle 12 to move, so that the opening between the upper baffle 11 and the lower baffle 13 is opened, allowing the solid waste to enter the fermentation chamber 15. Then the second motor 7 is started, and its output shaft drives the stirring paddle 14 to rotate, stirring the waste to promote the fermentation process.

[0026] Once the waste has finished fermenting, it needs to be discharged from the fermentation chamber 15. At this time, the opening and closing assembly starts to work. The first motor 2 drives the screw 16 to rotate. Since the screw 16 is threadedly connected to the opening and closing plate 8, the opening and closing plate 8 will slide along the receiving groove under the drive of the screw 16, thereby opening or closing the discharge port. After the discharge port is opened, the fermented waste is discharged from the discharge port under the action of gravity.
