Technical Field

[0001] This utility model relates to the technical field, specifically to a feeding device for biogas digesters. Background Technology

[0002] A biogas digester is a facility for producing biogas, a combustible gas produced from organic matter through microbial fermentation in an anaerobic environment under specific temperature, humidity, and pH conditions. Because this gas was initially discovered in swamps, lakes, and ponds, it is called biogas. With technological advancements, people can not only utilize this combustible gas but also treat industrial waste and livestock manure, reducing environmental pollution. Therefore, the development and utilization of biogas digesters is a very practical technology.

[0003] Existing biogas digester feeding devices typically use a crusher to grind the raw materials and then drop them directly into the biogas digester. However, these devices cannot control the material feed; the raw materials are simply ground and dropped downwards, which can easily result in insufficient grinding and poor grinding efficiency. Therefore, this paper proposes a new feeding device for biogas digesters to address these issues. Utility Model Content

[0011] Furthermore, a protective shell is fixedly connected to the outer surface of the processing box, and the protective shell is located on the outer surface of the linkage component.

[0012] Furthermore, the disassembly mechanism includes a fixing rod fixedly connected to the lower box, a locking rod hinged to the outer surface of the fixing rod, a locking plate fixedly connected to the outer surface of the upper box, and a nut threadedly connected to the outer surface of the locking rod.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] Please see Figure 1-5 The feeding device for a biogas digester in this embodiment includes a processing box 2, a frame 1 fixedly connected to the bottom of the processing box 2, a crushing mechanism 3 provided inside and outside the processing box 2, a pushing mechanism 4 provided inside the processing box 2, a disassembly mechanism 5 provided on the outer surface of the processing box 2, the processing box 2 is divided into an upper box and a lower box, the upper box and the lower box are hinged, and a feeding port 201 is opened on the top of the upper box.

[0024] The crushing mechanism 3 includes a motor 301 fixedly connected to the top of the frame 1. A linkage component 303 is provided on the outer surface of the output shaft of the motor 301. A screen frame 304 is fixedly connected inside the processing box 2. A rotating rod 305 is rotatably connected inside the screen frame 304. A crushing blade 306 is fixedly connected to the outer surface of the rotating rod 305. The screen frame 304 has an arc-shaped cross-section.

A scraper 307 is fixedly connected to the outer surface of the crushing blade 306 and fits against the screen frame 304.

[0025] The linkage component 303 can be composed of a sprocket and chain, or a pulley and belt, as long as it can achieve the linkage effect.

[0026] Driven by motor 301, the crushing mechanism 3 ensures that the raw materials are fully crushed in the processing box 2. The design of screen frame 304 and crushing blade 306 ensures that large particles of impurities in the raw materials are effectively removed, improving biogas fermentation efficiency. At the same time, the close fit design between scraper 307 and screen frame 304 prevents the accumulation of raw materials on screen frame 304, ensuring the continuity and stability of the crushing process.

[0027] Secondly, the feeding mechanism 4 includes a feeding bin 401 fixedly connected to the bottom of the processing box 2. An electric push rod 403 is fixedly connected inside the feeding bin 401, and a discharge platform 402 is fixedly connected inside the feeding bin 401. A pusher block 404 is fixedly connected to the outer surface of the output shaft of the electric push rod 403, and a feeding pipe 405 is fixedly connected to one end of the feeding bin 401. The discharge platform 402 has a trapezoidal cross-sectional shape, and the pusher block 404 is movably connected to the bottom of the discharge platform 402.

[0028] The pusher mechanism 4 driven by the electric pusher 403 realizes the automated feeding and unloading of raw materials. The trapezoidal design of the pusher 402 allows the raw materials to flow smoothly to the pusher block 404, avoiding the accumulation of raw materials in the processing box. The movable connection design of the pusher 404 ensures that the raw materials can be pushed evenly and stably to the feeding pipe 405, improving the feeding accuracy and efficiency.

[0029] Furthermore, a protective shell 302 is fixedly connected to the outer surface of the processing box 2. The protective shell 302 is located on the outer surface of the linkage component 303.

[0032] The working principle of the above embodiments is as follows:

[0033] (1) The feeding device for biogas digester has an electric push rod 403 driving the pushing mechanism 4, which realizes the automatic feeding of raw materials. The trapezoidal design of the feeding block 402 allows the raw materials to flow smoothly to the pushing block 404, avoiding the accumulation of raw materials in the processing box. The movable connection design of the pushing block 404 ensures that the raw materials can be pushed evenly and stably to the feeding pipe 405, improving the feeding accuracy and efficiency.

[0034] (2) The feeding device for biogas digesters uses a crushing mechanism 3 driven by a motor 301 to fully crush the raw materials in the processing box 2. The design of the screen frame 304 and the crushing blade 306 ensures that large particles of impurities in the raw materials are effectively removed, thereby improving the biogas fermentation efficiency. At the same time, the close fit design between the scraper 307 and the screen frame 304 prevents the accumulation of raw materials on the screen frame 304, ensuring the continuity and stability of the crushing process.
