Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a fermentation tank capable of intercepting organisms in the tank. Background Art

[0002] Overflow anaerobic fermentation tanks are mainly used to produce biogas. Crop straw, feces, etc. can be used as raw materials. Its principle is to use microorganisms to metabolize under anaerobic conditions to convert organic waste into biogas, biogas residue and biogas liquid. Biogas can be used and sold as clean energy, and biogas residue and biogas liquid are sold as biofertilizer for soil improvement and ecological circular agriculture. The working process of the anaerobic fermentation tank is to inject the raw materials into the fermentation tank for fermentation through a feed pump, and use external heat source, raw material concentration, feed amount and other measures to control the process parameters such as temperature and residence period of anaerobic fermentation. The biogas produced by fermentation is discharged through the exhaust pipe for collection and storage. At the same time, the reaction will produce biogas liquid and biogas residue, and the biogas residue will accumulate on the lower side of the tank. At this time, the solid matter in the pumped raw materials will be decomposed, and some anaerobic microorganisms will rise with the suspended matter and finally be discharged with the biogas liquid.

[0003] This type of overflow anaerobic fermentation tank has the following defects when in use: due to the reaction producing biogas slurry, some solid matter in the raw materials floats above the biogas slurry, and most of the microorganisms and organic components required for the reaction are located in these solids. The microorganisms and organic matter in these solids floating above the biogas slurry are not completely reacted, and at this time they float on the biogas slurry and stop reacting. When the raw materials are pumped in again, the new raw materials squeeze these solids floating above the biogas slurry into the biogas slurry pipe and discharge them from the tank, but the organic matter in these solid floating objects is not completely consumed, thus resulting in a waste of resources. Utility Model Content

[0004] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide a fermentation tank that can intercept the organisms in the tank, effectively solving the problem that the existing fermentation tanks easily cause waste of resources.

[0005] The technical solution is that the utility model includes a tank body with upper and lower axes, and left and right axial rotating shafts are respectively provided on the upper and lower sides of the tank body. A retaining plate coaxial with the tank body is provided on the rotating shaft. An arc-shaped accommodating groove is opened on the left side of the tank body. The left end of the rotating shaft is inserted into the accommodating groove and a gear is coaxially provided. A rack is provided in the accommodating groove, which is located behind the gear and meshed with the two gears. The rack can move up and down, and an air outlet pipe is provided at the upper end of the tank body.

[0006] Compared with the prior art, the utility model has the following beneficial effects: it can realize the fermentation reaction of raw materials and produce biogas, and at the same time, it can prevent the solids in the raw materials from floating upward due to the buoyancy of the biogas slurry through the blocking of the interception plate, resulting in insufficient reaction of the organic matter therein and waste of resources. Compared with the traditional fermentation tank, it can achieve the interception of the organisms in the tank, increase the biological retention time, and make the raw materials react fully.

[0018] In order to enable the rack 6 to move up and down, the rack 6 is slidably connected to the tank body 1 , and a stud 8 that is axially and rotatable up and down is provided in the receiving groove 4 , and the stud 8 is threadedly connected to the rack 6 .

[0019] In order to rotate the stud 8 , a motor 9 is provided in the receiving groove 4 and is located below the stud 8 . The output shaft of the motor 9 is coaxially and fixedly connected to the stud 8 .

[0020] In order to facilitate feeding, a feeding pipe 10 is provided at the right end of the tank body 1.

[0021] In order to facilitate the discharge of biogas slurry, a biogas slurry pipe 12 is provided at the upper end of the tank body 1 .

[0022] In order to facilitate the discharge of biogas residue, a biogas residue pipe 13 is provided at the lower end of the tank body 1.

[0023] When the utility model is used, the raw materials are firstly input into the tank body 1 through the feed pipe 10, and the organic matter in the raw materials reacts and ferments with the microorganisms in the tank body 1 to produce biogas and biogas, and the biogas is collected and stored through the gas outlet pipe 7 for use, and the produced biogas is accumulated at the lower side of the tank body 1, and then the solid matter in the raw materials has the force of floating upward due to the buoyancy of the biogas, but at this time, due to the obstruction of the interception plates 3 on the upper and lower sides, the solid matter is blocked and cannot float upward, so it is continuously located in the middle part of the tank body 1, and continuously reacts, so that the organic matter in the solid matter is consumed to the maximum extent to produce biogas, thereby increasing the biological retention period;

[0024] After a period of reaction, when the organic matter in the blocked fixed object is consumed to the maximum extent, the motor 9 is turned on to rotate forward, the motor 9 drives the stud 8 to rotate clockwise, the stud 8 drives the rack 6 thereon to move upward, the rack 6 moves upward to mesh with the two gears 5 and drives the two gears 5 to rotate clockwise, the two gears 5 drive the rotating shaft 2 to rotate clockwise, the rotating shaft 2 drives the intercepting plate 3 thereon to rotate, after rotating 90 degrees, the motor 9 is turned off, at this time the intercepting plate 3 rotates from being coaxial with the tank body 1 to being axially perpendicular to the tank body 1 again, removing the shielding of the fixed object, at this time the completely consumed solid matter floats upward due to the buoyancy of the biogas slurry, and then the biogas slurry is extracted from the tank body 1 through the biogas slurry pipe 12, and the biogas residue falls to the bottom of the tank body 1 due to the loss of biogas slurry;

[0025] After the discharge of the biogas slurry is completed, the motor 9 is turned on to reverse, and the motor 9 drives the stud 8 to rotate counterclockwise, and the stud 8 drives the rack 6 to move upward, and then the rack 6 meshes with the gear 5 and drives the gear 5 to rotate counterclockwise, and the gear 5 drives the two rotating shafts 2 to rotate counterclockwise, and then drives the two intercepting plates 3 to rotate counterclockwise. After the intercepting plates 3 rotate counterclockwise for a certain angle, they return to the initial position and become coaxial with the tank body 1 again, so as to intercept the solid matter in the tank body 1 again and prevent it from floating upward, so as to make the organic matter in the solid matter fully react and will not cause waste of resources. After using it for a period of time, the biogas residue pipe 13 is opened, and the biogas residue flows out through the biogas residue pipe 13 for discharge.
