Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of feed fermentation equipment, specifically relating to a feed fermentation equipment for livestock breeding. Background Technology
[0002] Feed fermentation is a technology to improve the efficiency of livestock farming. Through microbial metabolism, anti-nutritional factors can be degraded and probiotics can be produced. Currently, small and medium-sized farms generally use horizontal or vertical fermentation tanks. One problem is that the cast iron lids of traditional tanks rely on gravity pressing or single-point fasteners, which can easily lead to gaps of ≥2mm at the edge of the lid during peak gas production in fermentation, allowing oxygen to seep in. For example, silage requires an anaerobic environment with an oxygen concentration of <0.5%, and leakage can lead to the proliferation of butyric acid bacteria, causing feed spoilage.
[0003] Furthermore, adding additives requires completely removing the tank lid, exposing 100% of the tank opening. This increases the settling rate of airborne bacteria such as mold spores. Fermentation temperature fluctuations need to be controlled within ±2℃. The optimal temperature for EM bacteria is 35-38℃, but existing equipment mostly relies on external handheld thermometers with insufficient probe insertion depth, resulting in a temperature difference of up to 6℃ between the tank core and the tank wall, leading to uneven fermentation. The leachate discharge pipe runs directly to the bottom of the tank, resulting in a high rate of residue blockage, especially for feeds with a fiber content ≥15%. Frequent pipe disassembly and cleaning are required, with single downtimes exceeding 4 hours.
[0004] There is an urgent need for a feed fermentation device that can improve sealing reliability, ease of operation and process controllability. Therefore, a feed fermentation device for livestock breeding is proposed. Utility Model Content

Detailed Implementation
[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, such as Figure 1-3 As shown, a feed fermentation device for livestock farming includes a fermentation tank 1, which serves as the main container, providing a sealed fermentation space. The tank wall is made of 304 stainless steel, with a recommended thickness of ≥3mm, which is corrosion-resistant and has a pressure resistance of up to 0.2MPa. The fermentation tank 1 has a tank opening 2 at the top, a tank cover 3 at the top of the opening 2, support columns 4 on the side walls of the fermentation tank 1, a base 5 at the bottom of the support columns 4, and a discharge channel 6 at the bottom of the fermentation tank 1. The inner wall of the discharge channel 6 is mirror-polished. The base 5 is an H-shaped steel column fixed with anchor bolts, 500mm above the ground. The discharge cart can directly connect to the discharge channel 6, eliminating the need for material lifting.
[0023] The discharge channel 6 is L-shaped, and a discharge gate 7 is provided on the outside of the discharge channel 6. A fastening valve 8 is provided on the discharge gate 7 to lock the discharge gate 7 and control its opening and closing. A fastening device 9 for fixing the tank cover 3 is provided on the side wall of the tank opening 2. A feeding port 10 is provided on the tank cover 3, and a feeding cover 11 is provided on the feeding port 10. A vent valve 12 is provided on the feeding cover 11, and a locking device 13 for locking the feeding cover 11 is provided on the side wall of the feeding port 10. The feeding port 10 is an independent opening with a diameter of 150mm, used for adding bacterial agents or auxiliary materials midway. The vent valve 12 is a PP material diaphragm valve that automatically balances the internal and external air pressure, reducing the risk of contamination during operation. The vent valve 12 automatically releases pressure to prevent explosion.
[0024] The specific design of the aforementioned key components will be discussed in detail below:
[0025] An exhaust pipe 14 extends from one side of the tank opening 2, and an exhaust valve is installed on the exhaust pipe 14. The top of the exhaust pipe 14 discharges fermentation gases such as CO2. The exhaust valve supports pressure setting to prevent excessive gas pressure from damaging the seal, while also collecting usable gases.
[0026] A liquid injection pipe 15 is provided at the top of the side wall of the fermentation tank 1, and a liquid discharge pipe 16 is provided at the bottom of the side wall of the fermentation tank 1. A liquid injection valve is provided on the liquid injection pipe 15, and a liquid discharge valve is provided on the liquid discharge pipe 16. The liquid injection pipe 15 is connected to an external liquid tank to inject nutrient solution or adjust humidity. High-level injection avoids eroding the fermentation layer and maintains the stability of the material structure.
[0027] The fermenter 1 is provided with an openable and closable side wall cover 17. The side wall cover 17 is a quick-opening maintenance door with a sealing ring. The side wall cover 17 is used for cleaning the tank wall or troubleshooting without opening the tank cover 3, thus improving maintenance efficiency.
[0028] The fastening device 9 is a bolt structure, which uses 6-8 sets of M12 stainless steel bolts evenly distributed in a circular array as shown in the attached diagram to achieve rigid locking between the can lid 3 and the can opening 2. The locking device 13 is a quick-release handle structure. Rotating the handle drives the chuck to lock the feeding cover 11, which is faster than the traditional threaded cover and avoids damage to the fermentation environment during feeding.
[0029] A temperature sensor mounting port 18 is provided on the side wall of the fermenter 1. The temperature sensor mounting port 18 has an M20 threaded interface, which can accommodate a PT100 temperature sensor with a probe length greater than or equal to the radius of the tank body. A removable filter screen is provided at the inlet end of the drain pipe 16. The drain pipe 16 can discharge leachate, and the removable filter screen is a 304 stainless steel woven mesh with a pore size of 0.3 mm, used to intercept solid particles.
[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
