Description

Technical Field

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

[0002] Black membrane biogas digesters, also known as covered lagoons, are called "fully enclosed anaerobic ponds" when they are covered with membranes or geomembrane biogas digesters. The principle of biogas production is to use the seepage-proof and leak-proof characteristics of black membrane materials to form a closed space for anaerobic fermentation of manure and water, achieving the dual effect of sewage treatment and biogas production. At the same time, the black membrane absorbs solar heat to improve biogas production efficiency.

[0003] However, current methods of fermenting sewage and waste rely on the natural fermentation of microbial colonies to produce biogas. This method fails to stir the sewage and waste inside the biogas digester, thus hindering the contact between the raw materials and microorganisms and renewing the living environment within the digester. Consequently, the fermentation speed of the biogas digester is slow, resulting in low production efficiency. Utility Model Content

[0004] To address the problem that existing biogas digesters rely on natural bacterial fermentation to produce biogas, resulting in slow fermentation efficiency, this invention aims to provide a float device for black film biogas digesters.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a float device for a black film biogas digester, comprising a biogas digester body, a plurality of equally spaced base plates fixedly installed at the top of the biogas digester body, a base provided on the upper part of each of the plurality of base plates, a support rod fixedly installed at the top of each of the plurality of base plates, a rotating rod slidably provided in the middle of each of the plurality of support rods, a float body fixedly installed at the top of each of the plurality of rotating rods, a stirring rod fixedly installed on the upper part of each of the plurality of rotating rods, a driving block fixedly installed on one side of the lower part of each of the plurality of rotating rods, threaded grooves opened on the inner walls of each of the plurality of support rods, the driving blocks slidably locked inside the threaded grooves, a first spring fixedly installed at the lower part of each of the plurality of support rods, a rotating block rotatably installed at the bottom end of each of the plurality of rotating rods, and the top of each of the plurality of first springs fixedly installed at the bottom end of the rotating block.

[0006] Preferably, two mirror-distributed first fixing blocks are fixedly installed on the top of each of the plurality of base plates, and a second fixing block is rotatably installed on one side of the upper part of each of the two first fixing blocks. The lower part of one side of each of the plurality of second fixing blocks is in contact with the top of the base. A limit block is rotatably installed on the upper part of each of the plurality of first fixing blocks, and two mirror-distributed second springs are fixedly installed on the lower part of each of the plurality of limit blocks. A limit bead is fixedly installed on the end of each of the plurality of second springs away from the limit block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables the float to move up and down with the change in the liquid level inside the biogas digester under the buoyancy of the float, while the stirring rod rotates, thereby promoting contact between the raw materials and microorganisms, renewing the living environment inside the biogas digester, and accelerating the fermentation speed inside the biogas digester.

[0009] 2. This application enables more convenient overall installation of the mixing device, thereby increasing the installation speed for workers. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-6 As shown, this utility model provides a float device for a black film biogas digester, including a biogas digester body 1. Multiple equally spaced base plates 24 are fixedly installed at the top of the biogas digester body 1. Each base plate 24 has a base 25 on its upper part. Each base 25 has a support rod 26 fixedly installed at its top. Each support rod 26 has a rotating rod 21 slidably installed in its middle. Each rotating rod 21 has a float body 2 fixedly installed at its top. Each rotating rod 21 has a stirring rod 22 fixedly installed at its upper part. Each rotating rod 21 has a driving block 23 fixedly installed on one side of its lower part. Each support rod 26 has a threaded groove 231 on its inner wall. Each driving block 23 is slidably engaged inside the threaded groove 231. Each support rod 26 has a first spring 27 fixedly installed at its lower part. Each rotating rod 21 has a rotating block 271 rotatably installed at its bottom end. The tops of each first spring 27 are fixedly installed at the bottom end of the rotating block 271.

[0020] Two mirror-distributed first fixing blocks 3 are fixedly installed on the top of each of the multiple base plates 24. A second fixing block 31 is rotatably installed on one side of the upper part of each of the two first fixing blocks 3. The lower part of one side of each of the multiple second fixing blocks 31 is in contact with the top of the base 25. A limit block 32 is rotatably installed on the upper part of each of the multiple first fixing blocks 3. Two mirror-distributed second springs 33 are fixedly installed on the lower part of each of the multiple limit blocks 32. A limit bead 34 is fixedly installed on the end of each of the multiple second springs 33 away from the limit block 32.

[0021] Multiple support rods 26 are fixedly installed with telescopic rods 28 at their lower parts, and the tops of multiple telescopic rods 28 are fixedly installed at the bottom center of the rotating block 271. By setting the telescopic rods 28, the rotating rod 21 is more stable when moving up and down.

[0022] Each of the multiple base plates 24 has a slot 241 in the middle, and the lower part of each of the multiple bases 25 is slidably locked inside the slot 241. By setting the slot 241, the base 25 can be conveniently limited and installed.

[0023] Each of the multiple base plates 24 has two mirror-distributed first limiting grooves 242 on its upper part. Both sides of the multiple bases 25 are slidably locked inside the first limiting grooves 242. By setting the first limiting grooves 242, the bases 25 can be limited to prevent them from rotating.

[0024] Each of the multiple second fixing blocks 31 has a groove 321 in the middle that cooperates with the limiting block 32. By setting the groove 321, when the limiting block 32 and the second fixing block 31 are in the same direction, the second fixing block 31 can be opened by rotating the second fixing block 31 through the groove 321.

[0025] The middle of the multiple first fixing blocks 3 is provided with four symmetrically distributed second limiting grooves 341, and multiple limiting beads 34 are slidably locked inside the second limiting grooves 341. By setting the second limiting grooves 341, the limiting blocks 32 can be limited and fixed after the limiting beads 34 are locked inside the second limiting grooves 341.

[0026] Each of the top sides of the multiple second fixing blocks 31 is fixedly equipped with a handle 35, which makes it more convenient to rotate and open the second fixing blocks 31.

[0027] Working principle: In actual use, the internal liquid level of the float body 2 changes due to the fermentation reaction inside the biogas digester body 1, causing the float body 2 to move up and down with the liquid level. At the same time, it drives the rotating rod 21 to move up and down. Since the drive block 23, which is locked inside the threaded groove 231, is fixedly installed on the lower side of the rotating rod 21, the rotating rod 21 will rotate when it moves up and down because the threaded groove 231 limits the drive block 23. This will drive the stirring rod 22 to rotate, thereby stirring the liquid inside the biogas digester body 1 through the rotation of the stirring rod 22.

[0028] After the lower part of the base 25 is slidably locked inside the slot 241 and the first limiting slot 242, the second fixing block 31 is rotated and flipped so that one side of the second fixing block 31 contacts the top side of the base 25. By rotating the limiting block 32, the limiting bead 34 is compressed inward to squeeze the second spring 33. After rotating the limiting block 32 ninety degrees, the limiting bead 34 is located on one side of the second limiting slot 341 on the other side. The reaction force of the second spring 33 causes the limiting bead 34 to slide and lock inside the second limiting slot 341, thereby limiting and fixing the limiting block 32. Thus, the second fixing block 31 is limited and fixed by the limiting block 32, which facilitates the overall installation of the device.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
