Description

Technical Field

[0001] The utility model belongs to the field of kitchen waste treatment, and in particular relates to an aeration device of kitchen waste aerobic fermentation equipment. Background Art

[0002] Aerobic fermentation of garbage is a process that converts organic waste into stable inorganic substances and carbon dioxide. In this process, aeration is a key technology that can provide sufficient oxygen to promote the decomposition activities of microorganisms. However, traditional aeration devices usually aerate from the bottom and exhaust from the top, which will face a problem, that is, the water vapor generated during the aerobic fermentation of garbage will condense after encountering the top cover plate in the upward direction of the air flow, and then reflux and drip into the inside of the garbage fermentation material, resulting in a significant reduction in the efficiency of material moisture removal, uneven aeration during the fermentation process, and material agglomeration blocking the exhaust head. This not only affects the fermentation effect of the garbage material, but also increases the maintenance cost of the equipment. In addition, the existing aeration device only considers the extraction of water vapor and odor, but does not consider the timely discharge of sewage generated by garbage fermentation, which makes the fermentation effect worse. Therefore, it is necessary to design an aeration and exhaust device that improves the fermentation effect of garbage to solve the above problems, so as to reduce the moisture content of the garbage fermentation material and improve the efficiency of aerobic fermentation of garbage.

[0020] The present invention is further described and illustrated below in conjunction with the accompanying drawings and specific implementations. The technical features of each implementation of the present invention can be combined accordingly without conflicting with each other.

[0021] like Figure 1 As shown, an aeration and exhaust device for improving the fermentation effect of garbage provided by the utility model mainly comprises an air supply fan 1, an air collecting hood 3, an exhaust head 4, a pipeline fan 6, a pipeline system 8 and a drainage pipeline 9. The whole set of devices can discharge the sewage generated during the fermentation of garbage materials in time, and discharge the water vapor and odor from the bottom of the garbage fermentation material box, collect them through the pipeline system and discharge them into the odor treatment system, so as to prevent the problems in the prior art that the water vapor ascends and encounters the top cover plate to condense and flow back to the material, resulting in the slow removal of water from the garbage material and the reduction of the efficiency of microbial fermentation.

[0022] The structure and connection method of each component will be described in detail below.

[0023] In the utility model, the air supply fan 1 is connected to the top of the garbage fermentation material box through the air supply pipeline, the lower part of the garbage fermentation material box is sealed and connected with the air collecting hood 3, and the bottom of the garbage fermentation material box is evenly arranged with a plurality of air extraction heads 4. One end of the air extraction head 4 is located in the garbage fermentation material box, and the other end is located in the air collecting hood 3, and the garbage fermentation material box is connected to the air collecting hood 3 through the air extraction head 4.

[0024] The utility model installs the exhaust head 4 at the bottom of the box body and the air intake fan 1 at the top. Different from the traditional aeration method, air is exhausted at the bottom and air is taken in at the top, which can avoid the problem of water vapor generated by material fermentation encountering condensation reflux on the top cover plate.

[0025] As a preferred embodiment of the utility model, a heater 2 for heating the gas in the pipe is provided on the air supply pipeline. The air supply pipeline is heated by the heater 2, which can provide favorable conditions for the fermentation of garbage materials and maintain an aerobic fermentation temperature of 55-60°C. There can be multiple air supply pipelines, all of which are evenly arranged on the top of the garbage fermentation material box, and each air supply pipeline is equipped with an independent air supply fan 1 and a heater 2. The air is heated by the heater 2 to ensure that the outlet temperature is 55-60°C, which is conducive to the growth of microorganisms.

[0026] In the utility model, the air collecting hood 3 is horizontally arranged below the garbage fermentation material box, with the bottom of one side connected to the drainage pipeline 9 and the other side connected to the pipeline system 8. The end of the pipeline system 8 is provided with a pipeline fan 6 capable of exhausting and aerating, and a transparent pipe 5 is connected below the middle section.

[0027] In actual use, the pipeline fan 6 can be reversed through program control. In normal operation, it can be used for air extraction by forward rotation. When the air extraction head and the pipeline system are blocked, it can be reversed to aerate the air collection hood 3, provide pressure for the air collection hood 3, and use the backwash principle to flush out the materials blocking the holes of the air extraction head 4. The transparent tube 5 can observe the residual sewage in the pipeline system in real time, so as to control the opening of the transparent tube 5 and the solenoid valve 7 on the drainage pipeline 9, and cooperate with the control of the pipeline fan 6 to reverse to discharge the sewage. In addition, the solenoid valve 7 on the drainage pipeline 9 can be opened at a fixed time through program control to discharge the residual sewage in the air collection hood; or when the pipeline fan 6 is reversed, the solenoid valve 7 can be opened to make it easier to discharge the residual sewage by pressurizing.

[0028] As a preferred embodiment of the present invention, the transparent tube 5 can be made of acrylic material, and the pipe system can be made of PVC material. For ease of control, a solenoid valve 7 can be provided on both the drainage pipe 9 and the transparent tube 5. Figure 2 As shown, the exhaust head 4 located in the garbage fermentation material box is provided with a plurality of holes for exhausting air, and the inner cavity of the exhaust head 4 is filled with fillers to prevent the garbage fermentation material from entering. The fillers are preferably husks that are easy to obtain and cheap. In order to give full play to the functions of the corresponding pipelines, the end of the pipeline system 8 can be set upward to facilitate gas discharge, and the ends of the drainage pipeline 9 and the transparent tube 5 are both set downward to facilitate residual sewage discharge.

[0029] By using the above-mentioned aeration and air extraction device for improving the fermentation effect of garbage, the utility model also provides a control method, which is specifically as follows:

[0030] During normal operation, the air supply fan 1 provides air to the garbage fermentation material box through the air supply pipeline. By heating the air supply pipeline, favorable conditions can be provided for the fermentation of garbage materials in the garbage fermentation material box, and the aerobic fermentation temperature of 55-65°C can be maintained. At the same time, the solenoid valve 7 on the drainage pipeline 9 and the transparent tube 5 is closed, the air extraction head 4 is opened, and the pipeline fan 6 is adjusted to the air extraction mode. The water vapor and odor generated by the garbage fermentation materials during fermentation are discharged from the bottom of the garbage fermentation material box through the air extraction head 4, and are collected and discharged into the odor treatment system along the pipeline system 8. In this process, by observing the residual sewage in the transparent tube 5, the solenoid valve 7 on the drainage pipeline 9 is opened regularly for drainage, or the air extraction head 4 is closed and the pipeline fan 6 is adjusted to the aeration mode, and the residual sewage is discharged from the drainage pipeline 9 with the assistance of gas pressure.

[0031] When the exhaust head 4 is blocked, close the solenoid valve 7 and the air supply fan 1, adjust the pipeline fan 6 to the aeration mode, and use the gas pressure to flush the garbage fermentation materials blocking the holes of the exhaust head 4, thereby ensuring the smooth flow of the aeration and exhaust pipeline.

[0032] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
