Description

Technical Field

[0001] This utility model relates to the technical field of oxygenation devices, specifically to an oxygenation device for compost fermentation. Background Technology

[0002] The core purpose of composting is to transform organic waste into stable humus, achieving both harmless treatment and resource utilization. Taking high-carbon wastes such as straw, sawdust, and fallen leaves as examples, after aerobic fermentation, these materials can be converted into high-quality organic fertilizers or soil conditioners, which are widely used in agriculture, horticulture, and ecological restoration.

[0003] In existing technologies, some aerobic fermentation fertilizers often require being placed in a fermentation tank during fermentation. During this process, the fertilizer needs to be turned regularly to allow for contact between the inner layers of the fertilizer and the surrounding air. However, this method of composting by turning the fertilizer regularly is often inefficient, increases labor costs, and is inconvenient to operate. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a composting fermentation oxygenation device to solve the issues of low efficiency, increased labor costs, and inconvenience in operation associated with the existing aerobic fermentation method achieved by turning the compost pile.

[0005] This utility model is achieved using the following technical solution: a composting fermentation oxygenation device, including a fermentation tank, the bottom surface of which is provided with an installation groove, an oxygenation pipe network is provided in the installation groove, the oxygenation pipe network is provided with a plurality of air outlet holes, and one end of the oxygenation pipe network is connected to an air inlet pipe.

[0006] With the above structure, when fertilizer fermentation is required, simply spread the fertilizer in the fermentation tank, and then ventilate the oxygenation network through the air inlet pipe. Air is injected into the fertilizer through the oxygenation network, increasing the contact between the fertilizer and the air, thus improving the fermentation efficiency. Since sufficient oxygen is injected, frequent turning of the compost is no longer necessary, simplifying the operation process.

[0007] Preferably, the oxygenation network includes a main pipe connected to the air inlet pipe, with longitudinal connecting pipes arranged parallel to the main pipe on both sides. The main pipe and the longitudinal connecting pipes are connected by several transverse connecting pipes, forming a grid-like oxygenation network. The grid-like oxygenation network expands its coverage area, further increasing the contact area between fertilizer and oxygen, and accelerating fertilizer fermentation efficiency.

[0008] Preferably, one end of the fermentation tank is open, and the end of the main pipe away from the open end of the fermentation tank extends through the fermentation tank to the outside of the fermentation tank. The end of the main pipe extending to the outside of the fermentation tank is connected to the air inlet pipe. By extending the main pipe to the outside of the fermentation tank, the connection between the oxygenation network and the air inlet pipe is facilitated.

[0009] Preferably, the installation groove is a grid-shaped groove corresponding to the oxygenation pipe network. The grid-shaped groove design makes the installation groove more compatible with the oxygenation pipe network.

[0010] Preferably, the bottom surface of the fermentation tank is also provided with a mounting cover for covering the mounting groove, and the mounting cover has several ventilation holes. The mounting cover reduces the amount of fertilizer falling into the mounting groove and facilitates cleaning after fermentation.

[0011] Preferably, the mounting cover includes a main cover corresponding to the main pipe, a transverse cover corresponding to the transverse connecting pipe, and a longitudinal cover corresponding to the longitudinal connecting pipe. The sides of the main cover, transverse cover, and longitudinal cover are all inclined surfaces sloping inwards from bottom to top, and each inclined surface is provided with ventilation holes perpendicular to the inclined surface. The ventilation holes on the inclined surfaces allow for a wider radiation range of air entering the fertilizer, increasing the contact area between the fertilizer and oxygen, and further improving fermentation efficiency.

[0012] Preferably, the bottom sides of the main cover, horizontal cover, and vertical cover are all connected to limiting plates. The limiting plates are located within the mounting groove, and the corresponding pipelines are located between the two limiting plates and are in contact with the inner sides of the two limiting plates. The outer sides of the two limiting plates are in contact with the sidewalls of the corresponding mounting grooves. By setting the limiting plates, the mounting cover can only move up and down within the mounting groove, but not horizontally. Moreover, the location of the corresponding pipelines between the two limiting plates also makes the installation of the oxygenation network more stable.

[0013] Preferably, a blower is connected to the end of the air inlet pipe that is furthest from the oxygenation network. The blower effectively adjusts the amount of air entering the fertilizer, thus meeting the oxygen requirements of different fertilizers and increasing the applicability of the device.

[0014] Preferably, the blower is an air-suspended blower.

[0015] In summary, the beneficial effects of this utility model are as follows: 1. By setting up an oxygenation network, air can be directly "blown" into the interior of the fertilizer, thus providing sufficient oxygen for the fertilizer fermentation. This eliminates the need for frequent turning of the fertilizer, improving fermentation efficiency. Furthermore, operators only need to control the blower's on / off switch and adjust its power, requiring minimal intervention and making operation more convenient.

[0016] 2. By setting up the installation cover, the air from the vertically upward oxygenation network is dispersed to both sides, which further increases the radiation range of the "injected" air, increases the contact area between fertilizer and oxygen, and further improves the fermentation efficiency. In addition, the installation cover can also reduce the amount of fertilizer falling into the installation tank, thus facilitating subsequent cleaning work. Attached Figure Description

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 5As shown, this utility model provides a composting fermentation oxygenation device, including a fermentation tank 3 with one end open. The bottom surface of the fermentation tank 3 is provided with an installation groove 11. An oxygenation pipe network 9 is provided in the installation groove 11. The oxygenation pipe network 9 is provided with a plurality of air outlet holes 10 facing directly upward. An air inlet pipe 2 is connected to the open end of the oxygenation pipe network 9 away from the fermentation tank 3.

[0023] The reason why one end of the fermentation tank 3 is open is to make it easier to transfer fertilizer to the fermentation tank 3 or to remove the fermented fertilizer from the fermentation tank 3.

[0024] The oxygenation network 9 includes a main pipe 6 connected to the air intake pipe 2. Both sides of the main pipe 6 are provided with longitudinal connecting pipes 8 arranged parallel to the main pipe 6. The main pipe 6 and the longitudinal connecting pipes 8 are connected by several transverse connecting pipes 7. The main pipe 6, transverse connecting pipes 7, and longitudinal connecting pipes 8 form a grid-like oxygenation network 9. The grid-like oxygenation network 9 allows for a wider coverage area for the introduced air.

[0025] The end of the main pipe 6 that is away from the fermentation tank 3 extends through the fermentation tank 3 to the outside of the fermentation tank 3, and the end of the main pipe 6 that extends to the outside of the fermentation tank 3 is connected to the air inlet pipe 2.

[0026] The installation groove 11 is a grid-shaped groove corresponding to the oxygenation pipe network 9. That is, the installation groove 11 is also divided into a main groove for installing the main pipe 6, a horizontal groove for installing the horizontal connecting pipe 7, and a vertical groove for installing the longitudinal connecting pipe 8. The main groove, the vertical groove, and the horizontal groove constitute the grid-shaped installation groove 11.

[0027] like Figure 1 , Figure 3 , Figure 4 As shown, since the fertilizer is piled in the fermentation tank 3, if the top of the installation groove 11 is not sealed, the fertilizer will inevitably fall into the installation groove 11, and may even get stuck between the pipe and the inner wall of the installation groove 11, causing unnecessary trouble for subsequent cleaning. In order to solve this problem, an installation cover 4 for covering the installation groove 11 is provided on the bottom surface of the fermentation tank 3. The installation cover 4 is provided with several ventilation holes 5.

[0028] The mounting cover 4 includes a main cover body corresponding to the main pipe 6, a horizontal cover body corresponding to the horizontal connecting pipe 7, and a vertical cover body corresponding to the longitudinal connecting pipe 8. The sides of the main cover body, the horizontal cover body, and the longitudinal cover body are all inclined surfaces that slope inward from bottom to top, and each inclined surface is provided with a vent 5 perpendicular to the inclined surface.

[0029] The inclined vent 5 further diverts the air sprayed vertically upward from the oxygenation network 9, causing it to flow to both sides and "push" into the fertilizer. This makes the radiation area of ​​the air supplied by the device wider, increases the contact area between the fertilizer and the air, and improves the fermentation efficiency of the fertilizer.

[0030] Limiting plates 12 are connected to both sides of the bottom of the main hood, horizontal hood, and vertical hood. The limiting plates 12 are located within the mounting groove 11. The pipes corresponding to the limiting plates 12 are located between the two limiting plates 12 and are in contact with the inner sides of the two limiting plates 12. The outer sides of the two limiting plates 12 are in contact with the side walls of the corresponding mounting groove 11. By setting the limiting plates 12, the mounting hood 4 can only move up and down within the mounting groove 11, but cannot move horizontally. Moreover, the location of the corresponding pipes between the two limiting plates 12 makes the installation of the oxygenation pipe network 9 more stable.

[0031] The end of the air intake pipe 2 furthest from the oxygenation network 9 is connected to a blower 1. This blower 1 is preferably an air-suspended blower, which can provide higher output power and more precise control.

[0032] In the accompanying drawings of this utility model, Figure 5 It is in normal working order, and Figures 1 to 4 To demonstrate its specific structure more clearly, its orientation has been adjusted to vertical.

[0033] The operating principle of this device is as follows: First, install the mounting cover 4. Then, move the fertilizer into the fermentation tank. Select the appropriate output power of the blower 1 based on the amount of oxygen required by the fertilizer. Periodically, start the blower 1 to intermittently oxygenate the fertilizer in the fermentation tank 3. After fermentation is complete, remove the fermented fertilizer and clean the fermentation tank 3 to prevent it from affecting the fermentation of other fertilizers. During cleaning, the mounting slot 11 can be cleaned as needed. For example, when fermenting straw or other fertilizers, because the vent holes 5 on the mounting cover 4 are inclined and have a small diameter, straw generally does not fall into the mounting slot 11. Therefore, cleaning is unnecessary, or only simple processing is required.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
