Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a novel biogas slurry fermentation tank for dairy farms. Background Technology

[0002] Dairy farm biogas digesters are key facilities for treating livestock manure and realizing resource utilization. They are mainly used for anaerobic fermentation to produce biogas and biogas slurry. In a closed tank, dairy cow manure is decomposed into organic matter by microorganisms under anaerobic conditions, mainly producing biogas, biogas slurry, and biogas residue. The biogas is mainly composed of methane and can be used for power generation or heating. The biogas slurry can be used as liquid fertilizer, and the biogas residue is a solid residue that can be composted and used as base fertilizer.

[0003] Existing biogas digesters in dairy farms have the following shortcomings: the digester lacks a structure that disperses fibrous materials (such as uncrushed bedding) in the manure to form a hard shell, which hinders gas release and may even cause the pressure inside the digester to rise, posing a risk of bursting. As a result, the biogas digesters in dairy farms are not effective.

[0004] Therefore, those skilled in the art have proposed a novel biogas slurry fermentation tank for dairy farms to address the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned novel biogas slurry fermentation tank for dairy farms, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a new type of biogas fermentation tank for dairy farms, which solves the problem that the fermentation tank does not have a structure to disperse fibrous materials in the manure that float to the surface and form a hard shell, thus affecting gas release.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel biogas slurry fermentation tank for dairy farms, comprising:

[0009] The main body of the biogas slurry fermentation tank is used for the fermentation of waste materials such as dairy cow manure and flushing wastewater from dairy farms;

[0029] Example 1

[0030] Reference Figs. 1-3 This is the first embodiment of the present invention, which provides a novel biogas fermentation tank for dairy farms. This tank effectively breaks up the hard crust formed by floating fibrous materials in dairy cow manure, preventing it from affecting biogas release. The tank includes:

[0031] The main body of the biogas slurry fermentation tank is 100 cubic meters and is used for the fermentation of waste materials such as dairy cow manure and flushing wastewater from dairy farms.

[0032] It should be noted that the main body 100 of the biogas slurry fermentation tank is an existing facility. The dairy farm's cow manure is poured into the main body 100 of the biogas slurry fermentation tank. The dairy farm's cow manure is decomposed into organic matter by microorganisms under anaerobic conditions in a closed tank, mainly producing biogas, biogas slurry and biogas residue. Before use, the electrical terminals of each electrical device are electrically connected to the power supply and the electrical terminals of the controller through wires.

[0033] The height adjustment component 200 includes a fixed box 201 located on the inner wall of the main body 100 of the biogas slurry fermentation tank, and a sliding seat 206 is slidably connected to the fixed box 201.

[0034] The dispersing component 300 includes a telescopic cylinder 301 mounted on a slide block 206. The telescopic end of the telescopic cylinder 301 is connected to a piston rod 302. A servo motor 303 is mounted on the piston rod 302, and the output end of the servo motor 303 is connected to a dispersing rotating rod 304 via a rotating shaft.

[0035] In use, the height adjustment component 200 moves the slide 206 on the fixed box 201, thereby adjusting the height of the dispersing component 300. This allows the dispersing rod 304 to be positioned at the liquid level of the waste material within the main body 100 of the biogas digester. The telescopic cylinder 301 drives the servo motor 303 and the dispersing rod 304 to move. The servo motor 303 rotates the dispersing rod 304, which can break up the hard crust formed by fibrous materials floating in the manure of dairy cows in the dairy farm, thus avoiding affecting the release of biogas and improving the effectiveness of the new biogas digester in the dairy farm. The height adjustment component 200 can adjust the height of the dispersing component 300 and can disperse the hard crust formed at different liquid levels, thus having few limitations in use.

[0036] Example 2

[0037] Reference Figs. 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, the height adjustment component 200 also includes a reduction motor 202 fixedly connected to the fixed box 201, and the output end of the reduction motor 202 is connected to a lead screw 203. The end of the lead screw 203 away from the reduction motor 202 is rotatably connected to the inner wall of the fixed box 201 through a bearing.

[0038] The lead screw 203 is threadedly connected to a threaded sleeve 204, which is fixedly connected to the slide block 206. The fixed box 201 is provided with a through guide groove 205, which is slidably set with the slide block 206. The operation of the reduction motor 202 drives the lead screw 203 to rotate. After the threaded sleeve 204, which is threadedly connected to the lead screw 203, is slidably limited by the through guide groove 205 and the slide block 206, the dispersion height of the dispersion component 300 on the slide block 206 can be adjusted.

[0039] The sliding block 206 has a sealing slide plate 208 fixedly connected to one end away from the geared motor 202. Two sets of sealing seats 207 are fixedly connected to the fixed box 201, and both sets of sealing seats 207 are slidably connected to the sealing slide plate 208 for sealing the through guide groove 205. During the sliding of the sliding block 206, the sealing slide plate 208 can slide between adjacent sealing seats 207, which can block the through guide groove 205 and prevent dairy waste in the fermentation tank from entering the fixed box 201, thus playing a protective role.

[0040] The dispersing component 300 also includes a mounting block 305 fixed to the servo motor 303, and the mounting block 305 has a through hole.

[0041] The piston rod 302 is fixedly connected to a threaded rod 306 that is connected to a through hole. Two sets of nuts 307 are threadedly connected to the threaded rod 306, and the two sets of nuts 307 are respectively attached to both ends of the mounting block 305. The threaded rod 306 is installed in the through hole in the mounting block 305. After rotating the two sets of nuts 307, the threaded rod 306 can be fixed, which facilitates the disassembly and assembly of the servo motor 303 and makes it easy to replace and maintain.

[0042] The main body 100 of the biogas slurry fermentation tank is equipped with a sealing cover and a discharge pipe. The sealing cover is not shown in the figure and can seal the fermentation tank. The discharge pipe is used to discharge the biogas slurry.

[0043] The outer surface of the dispersing rod 304 is coated with an anti-corrosion coating, and a sealing gasket is provided on the sealing slide plate 208. The anti-corrosion coating plays a role in preventing corrosion and avoiding long-term corrosion of the dispersing rod 304 in the fecal liquid. The sealing gasket improves the sealing performance of the sealing slide plate 208 and the through guide groove 205.

[0044] In use, the electrical terminals of each electrical device are electrically connected to the power supply and the electrical terminals of the controller through wires. The geared motor 202 on the height adjustment component 200 is turned on. The working of the geared motor 202 drives the lead screw 203 to rotate. After the threaded sleeve 204, which is threaded to the lead screw 203, slides through the guide groove 205 and slide block 206, the dispersion height of the dispersion component 300 on the slide block 206 can be adjusted so that the dispersion rotating rod 304 is in contact with the liquid level of the waste in the main body 100 of the biogas slurry fermentation tank.

[0045] The telescopic cylinder 301 on the dispersing component 300 drives the servo motor 303 and the dispersing rod 304 to move. The operation of the servo motor 303 drives the dispersing rod 304 to rotate, which can break up the hard shell formed by the floating fibrous material in the manure of dairy cows in the dairy farm, so as to avoid affecting the release of biogas and improve the use effect of the new biogas fermentation tank in the dairy farm. The height adjustment component 200 can adjust the height of the dispersing component 300, which can disperse the hard shell formed by liquid surface at different heights, and has few limitations in use.

[0046] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
