Description

Technical Field

[0001] This utility model relates to the field of composting fermentation tank technology, and in particular to a ventilated and deodorized composting fermentation tank. Background Technology

[0002] Existing composting fermentation tanks are mostly semi-open or simply covered structures, with natural ventilation at the bottom or mechanical turning to supply oxygen. The malodorous gases such as ammonia and hydrogen sulfide produced during the fermentation process are directly released, causing the odor concentration at the factory boundary and surrounding environment to exceed the standard.

[0003] Because the fermentation tank has a simple structure and cannot be effectively sealed, the high concentration of malodorous gases produced during the fermentation process directly escapes into the environment, seriously affecting the air quality at the factory boundary and in the surrounding area, making it difficult to meet environmental protection requirements. Utility Model Content

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 8 This embodiment provides a ventilated and deodorized composting fermentation tank, including a frame 10, on which a fermentation tank 11 is fixedly installed. The fermentation tank 11 is used for fermenting compost. A door 12 is provided on one side of the fermentation tank 11. By opening the door 12, compost can be transported into the fermentation tank 11. A cover plate 13 is installed on the top of the fermentation tank 11 by screws. A sealing structure is provided between the cover plate 13 and the door 12 and the fermentation tank 11 to prevent the leakage of odors emitted during compost fermentation. A ventilation component 14 that can deodorize during compost fermentation is installed on the fermentation tank 11. A mixing component 15 that can stir the fertilizer is also installed on the fermentation tank 11.

[0017] Reference Figure 4 - Figure 8 Specifically, in order to ventilate and deodorize the fermentation tank 11, a ventilation assembly 14 is provided. The ventilation assembly 14 includes a filter screen 141 placed inside the fermentation tank 11. The filter screen 141 is a pre-existing anti-seepage filter screen 141. The anti-seepage filter screen 141 can prevent fine materials from clogging the air holes on the aeration pipe 145. A plug rod 142 is fixedly installed at the bottom edge of the frame of the filter screen 141. A mounting bracket 143 is symmetrically installed on the fermentation tank 11. Several holes 144 are opened on the mounting bracket 143. The size of the holes 144 is adapted to the plug rod 142. In the initial state, the holes 144 are inserted into the filter screen 141, thus playing a role in installing the filter screen 141. By removing the top cover plate 13, such as... Figure 3As shown, the filter screen 141 can then be pulled upwards to remove it from the mounting bracket 143. At the same time, a drain pipe is provided at the bottom of the frame 10, through which the liquid produced at the bottom of the frame 10 due to composting fermentation can be drained.

[0018] In more detail, the aeration pipe 145 is fixedly installed inside the fermentation tank 11, and the connecting pipe 146 is connected between several aeration pipes 145. Air can be supplied to the interior of the fermentation tank 11 through the aeration pipe 145, so that the compost can fully contact the air for fermentation. The air pump 147 is fixedly installed on the frame 10, and the air supply pipe 148 is set between the connecting pipe 146 and the air pump 147. Air can be transported from the air pump 147 to the connecting pipe 146 through the air supply pipe 148, and then the air can be transported to several aeration pipes 145 through the connecting pipe 146.

[0019] In more detail, the aeration pipe 145 is located below the filter screen 141, and several air holes are opened on the aeration pipe 145 to allow air inside the aeration pipe 145 to be discharged. There are two air supply pipes 148, one of which is connected to the exhaust port of the connecting pipe 146 and the air pump 147, and the other is connected to the air inlet of the air pump 147. By starting the air pump 147, a negative pressure is generated at the air inlet of the air pump 147, which draws in air. Then, a positive pressure is generated at the exhaust port of the air pump 147, which delivers the air through the air supply pipe 148 to the connecting pipe 146, and then through the connecting pipe 146 to deliver the air to several aeration pipes 145. The air inside the aeration pipes 145 can be discharged through the air holes, so that the compost can fully contact the air for fermentation.

[0020] In more detail, an air pump 149 is fixedly installed on one side of the frame 10, and an exhaust pipe 1410 is provided between the cover plate 13 and the air pump 149. The exhaust pipe 1410 can extract and treat the air (high humidity, high temperature, and high odor) generated during composting, thereby providing ventilation and deodorization for the fermentation tank 11.

[0021] In more detail, there are two exhaust pipes 1410. One is connected to the cover plate 13 and the air inlet of the second air pump 149, and the other is connected to the air outlet of the second air pump 149 and the pre-washing tower. During the composting fermentation process, high humidity, high temperature and high odor gases are generated. At this time, by starting the second air pump 149, a negative pressure is generated at the air inlet of the second air pump 149, so that the exhaust pipe 1410 can draw out the gas in the fermentation tank 11 and deliver the air to the pre-washing tower through the positive pressure of the air outlet. Through the aeration pipe 145 at the bottom, the air can circulate in the fermentation tank 11, thereby completing the ventilation and deodorization of the fermentation tank 11. Then, the pre-washing tower cools, removes dust and removes some of the ammonia in the gas. Finally, the gas is purified by passing through a biological filter and deep treatment.

[0022] Reference Figure 2 - Figure 5 Specifically, in order to ensure that the fertilizer fully contacts the air for fermentation, a mixing component 15 is provided. The mixing component 15 includes a rotating rod 151 rotatably mounted on the fermentation tank 11, a stirring blade 152 and a driven gear 153 respectively mounted on the rotating rod 151. The rotating rod 151 enables the stirring blade 152 and the driven gear 153 to rotate synchronously. The stirring blade 152 can stir the fertilizer, allowing it to fully contact the air for fermentation. A drive gear 155 is fixedly mounted on the output end of a servo motor 154. The servo motor 154 is fixedly mounted on the frame 10. The servo motor 154 can drive the drive gear 155 to rotate, and the drive gear 155 meshes with the driven gear 153. When the drive gear 155 rotates, the meshing causes the driven gear 153 to also drive the rotating rod 151 to rotate, thereby enabling the stirring blade 152 to rotate and stir the fertilizer inside the fermentation tank 11.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
