Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and specifically relates to an automatic feeding device for biogas digesters. Background Technology

[0002] Waste organic matter is decomposed and fermented in a biogas digester to produce biogas. A small, circular opening is typically located at the top of the digester, where a cover is placed. To promote biogas production and the decomposition of organic matter, specific biogas-producing bacteria are introduced into the digester. These bacteria generally consist of various microorganisms, including methanogens, methanogenic flagellates, and other bacteria and archaea involved in the biogas fermentation process. Cultivated under specialized conditions, these bacteria can tolerate low-oxygen, high-temperature, and acidic environments and effectively decompose organic matter, thus promoting the production of more biogas. However, in practice, the biogas-producing bacteria mixture is poured into the digester through the opening at the top by opening the digester cover. However, pouring the bacteria directly into the digester through the top opening causes them to accumulate in a small area below the opening, which is not conducive to the rapid decomposition and fermentation of organic matter. Utility Model Content

[0003] This invention provides an automatic microbial inoculation device for biogas digesters. It uses a rotating spray method to evenly spray liquid microbial inoculation into the surrounding area of ​​the biogas digester, increasing the inoculation range and facilitating the rapid decomposition and fermentation of organic matter.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An automatic biogas digester microbial inoculation device includes a frame, a rigid pipe, and a microbial storage tank. A bidirectional screw is rotatably mounted inside the frame, and a motor is connected to the bidirectional screw. Movable blocks are connected to both sides of the bidirectional screw and the frame. The bidirectional screw can drive the two movable blocks to move relative to each other or closer together on the frame. The lower ends of the movable blocks extend below the bottom of the frame. The rigid pipe is located in the middle of the frame, and its lower end extends below the movable blocks and is rotatably fitted with a hemispherical shower head. A driving mechanism is connected between the hemispherical shower head and the rigid pipe to drive the hemispherical shower head to rotate at the lower end of the rigid pipe. A water pump is connected to the bottom of the microbial storage tank, and the water pump is connected to the rigid pipe via a flexible hose.

[0006] Furthermore, the hemispherical shower head includes a rotating tube rotatably sleeved on the lower end of a rigid pipe, the lower end of the rotating tube being provided with a hemispherical shell, and a plurality of spray holes evenly distributed on the spherical surface of the hemispherical shell, and the driving mechanism being connected between the rotating tube and the rigid pipe.

[0007] Furthermore, the drive mechanism includes a gear ring sleeved on the rotating tube and a second motor mounted on the rigid tube. The output shaft of the second motor is provided with a gear, which meshes with the gear ring.

[0008] Furthermore, the bow frame is equipped with a carrying handle.

[0009] Furthermore, the bottom of the movable block is provided with a locking block, and the two locking blocks are arranged opposite each other. Both sides of the top of the storage tank are provided with locking grooves that match the locking blocks, and the middle of the top of the storage tank is provided with an avoidance groove that is compatible with the hemispherical shower head.

[0010] Furthermore, the water pump is located on the side wall of the storage tank.

[0011] Furthermore, the bottom of the storage tank is equipped with multiple rollers.

[0012] Furthermore, the top of the storage tank is equipped with a detachable dosing cover.

[0013] Furthermore, the bottom of both sides of the bow frame is provided with support seats.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. After placing the bow frame over the opening of the biogas digester, use the double-headed screw to drive the two moving blocks to move away from each other on the bow frame, so that the two moving blocks are firmly supported inside the opening of the biogas digester, which facilitates quick fixation and prevents tipping over during rotation and spraying.

[0016] 2. The liquid bacteria in the storage tank is pumped out by a water pump and sprayed into the biogas digester by a hemispherical sprinkler. The drive mechanism drives the hemispherical sprinkler to rotate at the lower end of the rigid pipe to spray. Under the action of centrifugal force and water pressure, the range of bacteria dispensing is increased, which is conducive to the rapid decomposition and fermentation of organic matter.

[0017] 3. Place the two movable blocks on the top sides of the storage tank, and then use the double-ended screw to move the two movable blocks closer to each other, so that the two locking blocks are locked in the slots. This allows the arch frame to be quickly fixed on the storage tank, making it easy to carry. Attached Figure Description
