Description

Technical Field

[0001] This utility model relates to the field of biogas fertilizer production, specifically to an integrated mixing and composting device for producing solid organic fertilizer from biogas slurry. Background Technology

[0002] Biogas slurry is a bright brown liquid formed after the fermentation of organic matter. It contains amino acids, cellulose, cellulase, protein, ribose, auxins, gibberellins, unsaturated fatty acids, and certain antibiotics. Biogas slurry is mainly used for seed soaking, foliar fertilization, mixing with nutrient soil, as a flower and fruit preservative, as a mother liquor for hydroponics, and for growing flowers. The organic residue and waste liquid after biogas fermentation are collectively called biogas fermentation residue, which consists of both solid and liquid components. In a biogas digester, these two components are unevenly distributed. The solid matter floating on the surface is called scum, and this layer has a complex composition, including organic debris that has decreased in density after fermentation, as well as straw and firewood that have not been fully degreased. The middle part of the biogas digester is liquid (the upper and middle parts are clear liquid, and the lower part is a suspension), usually called biogas slurry; the bottom layer is muddy sediment, called biogas residue. In biogas digesters lacking a stirring device, the stratification of solid and liquid is very common, which has a certain impact on biogas production and biogas fertilizer output.

[0003] A search revealed that Chinese Patent Publication No. CN222889727U discloses "a mixing device for producing solid organic fertilizer from biogas slurry, comprising a feeding box and a mixing assembly. The mixing assembly includes two first motors, two crushing rollers, a mixing box, a liquid pump, a discharge pipe, a second motor, a connecting shaft, and multiple stirring rods. Straw is fed into the feeding box from the top, falling between the two crushing rollers. The two first motors drive the two crushing rollers to rotate, crushing the straw. The crushed straw powder falls into the mixing box. The liquid pump extracts biogas slurry and introduces it into the mixing box to mix with the straw powder. The second motor drives the connecting shaft and multiple stirring rods to rotate, fully mixing the straw powder and biogas slurry in the mixing box. This application can crush the straw before mixing it with biogas slurry, increasing the contact area between the straw and biogas slurry, thereby improving fermentation efficiency." However, the following defects still exist:

[0004] (1) Currently, the integrated mixing and composting devices for producing solid organic fertilizer from biogas slurry on the market have low overall filtration capacity, making them inconvenient to filter. Furthermore, the addition of materials to increase compostability is not very convenient.

[0005] (2) Currently, the integrated mixing and composting equipment for producing solid organic fertilizer from biogas slurry on the market has low overall compostability and is not easy to mix and form quickly, thus reducing its overall usability.

[0006] Therefore, we have made improvements and proposed an integrated mixing and composting device for producing solid organic fertilizer from biogas slurry. Utility Model Content

[0020] In the solution of this utility model:

[0021] 1. The biogas slurry and compost mixture are introduced into the composting bin through the filter port and feeding port inside the bin. When the filter port is working, the power input terminal of the pump body is connected to the external power supply. The pump body draws biogas slurry from the outside through the water inlet pipe and discharges it into the composting bin through the water outlet pipe. When mixed composting is required, the user can pull out the insert plate from the insertion port on the surface of the bin by moving the handle, so that the material from the feeding port can be poured into the composting bin. This allows for multiple introduction and mixing, increasing the overall usability. Therefore, the integrated device for mixing and composting solid organic fertilizer from biogas slurry has high overall filtration efficiency, making filtration treatment easy, and the addition of materials to increase compostability is relatively convenient.

[0022] 2. During the mixing process, the power input terminals of multiple motors are connected to an external power source. The motors drive the input terminals of the shafts connected to their output terminals to rotate. The shafts then drive a fixed rod connected to one end to rotate within the composting bin. The fixed rod, in turn, drives multiple annular stirring rods fixedly connected to its surface to rotate, rapidly mixing the fertilizer and increasing its mixability. Consequently, the integrated mixing and composting device for producing solid organic fertilizer from biogas slurry exhibits high overall compost mixability, facilitating rapid mixing and shaping, thereby improving its overall usability.

[0036] like Figure 2 As shown, the surface of the housing 501 has an insertion port 504, the inside of which is connected to the inside of the feeding port 503. An insertion plate 505 is connected inside the insertion port 504, which facilitates connection with the insertion plate 505, allowing the insertion plate 505 to close and open the bottom of the feeding port 503.

[0037] like Figure 5 As shown, a horizontal plate 507 is fixedly connected to one side of the surface of the box 501. A second connecting hole 509 is provided on the surface of the horizontal plate 507 to increase the connection fixing point.
