Description

Technical Field

[0001] The present invention belongs to the technical field of manure treatment, and in particular relates to a manure treatment device based on biological conversion. Background Art

[0002] The biological conversion technology of manure mainly includes the use of microbial flora, environmentally friendly insects and animal protein conversion technology. Among them, environmentally friendly insects such as black soldier flies are used to convert livestock and poultry manure. Black soldier flies can efficiently feed on and process various livestock and poultry wastes, and can convert manure into animal protein raw materials for livestock and poultry feed, while the residual matter is returned to the field as organic fertilizer. Black soldier flies can grow well in a suitable environment, which helps to convert manure, and has low processing costs, high resource efficiency, and no secondary pollution. When using black soldier flies for manure treatment, it is generally necessary to spread the larvae in the manure treatment pool, but in actual work, it is difficult to achieve uniform spreading of the larvae.

[0007] A feed port is provided on the upper portion of the sealing cylinder, and the feed port is blocked by a detachable cover plate.

[0008] Furthermore, the screening mechanism includes a screen located below the sealing cylinder, the outer edge of the screen is provided with enclosures, and guide rods are fixedly provided on the upper outer edges of the enclosures on both sides; A mounting frame is fixedly arranged between the two movable seats, and the mounting frame includes symmetrically arranged cross beams, and the inner sides of both ends of the cross beams are penetrated by sliding grooves that cooperate with the guide rods.

Therefore, when adding feces in the later stage, the feces can be directly inverted on the screen to achieve uniform placement of feces, avoid excessive concentration of feces, and screen out large particles of impurities that affect the feeding of black soldier flies.

[0017] After the conversion is complete, the winch is activated, and the wire rope is pulled through the upper and lower guide wheels to pull the push plate. The push plate slides against the tank wall via the upper and lower rollers, pushing the debris and black soldier flies toward the open end. The hydraulic rod / electric push rod pushes the door open, centrally discharging the debris and black soldier flies.

[0018] The technical solution provided by the embodiment of the present invention has the following beneficial effects: the sealing cylinder realizes adaptive opening and closing of the discharge port through an eccentric swing mechanism, and synchronously completes the quantitative spreading of black soldier fly larvae during movement; the crank-connecting rod-driven screen, combined with the splash-proof design of the enclosure, ensures the uniformity of the black soldier fly delivery. In addition, when feces and sewage are added to the treatment pool at a later stage, the screen can also be used to achieve screening and uniform delivery of feces and sewage. The push plate slides against the pool wall through four-way rollers, and cooperates with the two-way traction of the winch to remove the residue and black soldier flies at the bottom of the pool, which helps to collect black soldier flies.
