Technical Field

[0001] The utility model belongs to the technical field of anaerobic reactors, and particularly relates to a completely mixed anaerobic reactor for dry treatment of food waste. Background Technique

[0002] A completely mixed anaerobic reactor is a device commonly found in biological treatment systems for treating organic waste, including food waste. The design of such reactors aims to decompose organic matter into biogas and organic fertilizer through the metabolic activities of microorganisms in an oxygen-free environment.

[0003] At present, there are still many problems in the actual operation of existing completely mixed anaerobic reactors. For example, the efficiency of stirring the internal garbage and mixed sewage is poor, resulting in a low volatilization effect of biogas, which cannot be fully utilized. Moreover, the inner wall of the anaerobic reactor is easily corroded under the long-term adhesion of sewage and garbage. However, the anaerobic reactor itself is relatively tall, making it inconvenient to clean the bottom end of the inner wall of the anaerobic reactor.

[0004] Therefore, a completely mixed anaerobic reactor for dry treatment of food waste is needed to solve the problems of poor efficiency in stirring garbage and mixed sewage and inconvenient cleaning of the bottom end of the inner wall of the anaerobic reactor in the prior art.

Specific embodiments

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-5 , the present utility model provides a fully mixed anaerobic reactor for dry treatment of food waste, including an anaerobic tank 1, a transmission rod 8, and a cleaning plate 15. One side of the outer wall of the anaerobic tank 1 is fixedly provided with a support 2, one end of the support 2 is fixedly provided with a screw conveyor 3, the output end of the screw conveyor 3 is connected to the top end inner wall of the anaerobic tank 1, one side of the top end of the anaerobic tank 1 is provided with a gas-liquid separator 4, the other side of the anaerobic tank 1 is fixedly provided with a servo motor 5, the center of the top end of the anaerobic tank 1 is fixedly provided with a protective part 6, and a transmission mechanism 7 is arranged on the inner wall of the protective part 6;

[0024] A plurality of crosses 10 are fixedly arranged on the bottom outer wall of the transmission rod 8, mounting rings 11 are fixedly arranged on the outer walls of the crosses 10, and a cleaning mechanism 16 is arranged at the connection end of the cross 10 and the mounting ring 11.

[0025] Through the transmission mechanism 7, it can mainly drive the transmission rod 8 and the mounting rod 9 to rotate simultaneously, so as to drive the positioning ring 12 to rotate. By the rotation of the positioning ring 12, a centrifugal force can be generated, which can drive the rotating part 13 to rotate. Thus, stirring can be realized, and at the same time, the cross 10 and the mounting ring 11 can be driven to rotate, so as to clean the bottom end inner wall of the anaerobic tank 1.

[0026] Through the cleaning mechanism 16, when the cross 10 and the mounting ring 11 rotate, a centrifugal force can be generated, which can drive the movable block 164 to be stressed, and then drive the cleaning plate 15 to be stressed, so as to clean the inner wall of the anaerobic tank 1.

[0027] Furthermore, asFigure 1 , Figure 2 , Figure 3 As shown, it is worth specifically explaining that the transmission mechanism 7 includes a first bevel gear 71. The center of the first bevel gear 71 is fixed to the driving end of the servo motor 5, and both sides of the outer wall of the first bevel gear 71 are meshed with a second bevel gear 72 and a third bevel gear 73 respectively.

[0028] Further, as shown in Figure 3 and Figure 4 it is worth specifically explaining that the center of the second bevel gear 72 is fixed to the top end of the transmission rod 8, and a mounting rod 9 is fixed at the center of the third bevel gear 73. The transmission rod 8 passes through the centers of the third bevel gear 73 and the mounting rod 9 and rotates. A plurality of positioning rings 12 are fixed to the outer wall of the mounting rod 9, and rotating members 13 are rotatably mounted at the four corners of the outer wall of the positioning ring 12. Breaking water members 14 are fixed to both sides of the outer wall of the rotating member 13.

[0029] Through the breaking water members 14, it is possible to break the water source on the inner wall of the anaerobic tank 1, reduce the resistance of the water source, and improve the stirring effect at the same time.

[0030] The working process of this solution is as follows: First, the food waste is transported to the inner wall of the anaerobic tank 1 through the auger conveyor 3 to generate biogas. At the same time, the servo motor 5 is started to rotate the first bevel gear 71, and further drive the second bevel gear 72 and the third bevel gear 73 to rotate simultaneously. When the second bevel gear 72 rotates, it drives the transmission rod 8 to rotate, and further drives the cross 10 and the mounting ring 11 to rotate. When the cross 10 and the mounting ring 11 rotate, a centrifugal force is generated, which can drive the movable block 164 to be stressed, stretch the stress spring 163, drive the cleaning plate 15 to move, and then clean the inner wall of the anaerobic tank 1. At the same time, a brush 17 is fixed to the bottom of the mounting ring 11 to further clean the bottom inner wall of the anaerobic tank 1. Through two-way stirring, the stirring effect of the internal food waste can be improved, and the volatilization effect of biogas can be improved.

[0031] According to the above working process, it can be seen that the transmission mechanism 7 can mainly drive the transmission rod 8 and the mounting rod 9 to rotate in two directions, thereby improving the stirring effect. And through the cleaning mechanism 16, the inner wall of the anaerobic tank 1 can be cleaned to avoid inconvenient subsequent cleaning.

[0032] Further, as shown in Figure 2 , Figure 4 and Figure 5As shown in the figure, it is worth specifically stating that the cleaning mechanism 16 includes a plurality of movable slots 161. The plurality of movable slots 161 are opened at the connection between the cross 10 and the mounting ring 11. Limiting rods 162 are fixed to the inner walls of the movable slots 161. A stress spring 163 is sleeved on the outer wall of the limiting rod 162. One end of the stress spring 163 is fixed to the inner wall of the movable slot 161, and the other end of the stress spring 163 is fixed with a movable block 164. The other ends of the movable blocks 164 are commonly fixed to the cleaning plate 15 on the corresponding side.

[0033] The centrifugal force generated by the movable block 164 enables it to drive the cleaning plate 15 to move, so that it can be attached to the inner wall of the anaerobic tank 1, thereby realizing the cleaning of the inner wall of the anaerobic tank 1.

[0034] Further as Figure 5 shown, it is worth specifically stating that the movable block 164 is installed on the outer wall of the limiting rod 162 in a limited sliding manner.

[0035] Furthermore as Figure 1 、 Figure 2 、 Figure 4 shown, it is worth specifically stating that a brush 17 is installed at the bottom of one of the mounting rings 11. Both the cleaning plate 15 and the brush 17 are attached to the inner wall of the anaerobic tank 1.

[0036] The brush 17 can mainly realize the cleaning of the bottom inner wall of the anaerobic tank 1, thereby improving the cleaning effect of the bottom end of the inner wall of the anaerobic tank 1.

[0037] In summary: The transmission mechanism 7 can mainly realize driving the transmission rod 8 and the mounting rod 9 to rotate simultaneously, so as to drive the positioning ring 12 to rotate, and through the centrifugal force, it can drive the rotating part 13 to rotate, thereby realizing stirring. At the same time, it can also drive the cross 10 and the mounting ring 11 to rotate, so as to realize the cleaning of the bottom end of the inner wall of the anaerobic tank 1.

[0038] The gas-liquid separator 4 and the servo motor 5 can be purchased on the market. The gas-liquid separator 4 and the servo motor 5 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
