Abstract
Description
Technical Field
[0001] This utility model relates to the field of composting technology, and more specifically, to a composting aeration device. Background Technology
[0002] Aerobic composting is a process of producing organic fertilizer by using waste materials (such as livestock and poultry manure, urban garbage, edible fungi production waste and agricultural crop straw) as mixed raw materials, and fermenting, maturing and decomposing them under high temperature and aerobic conditions.
[0003] Currently, to promote the composting process, aerobic composting typically employs forced ventilation. The specific measures are as follows: an aeration pipe is buried at the bottom of the composting fermentation container, the compost material is placed into the fermentation container and covered with a film, and air is supplied to the aeration pipe through an air supply device (such as a blower) to form aerobic fermentation. However, this method is prone to uneven airflow distribution, resulting in uneven aeration in different areas of the material. Moreover, the aeration pipe, which is in direct contact with the material, is easily blocked by the material, affecting the aeration effect and thus impacting the overall composting maturity and quality stability. Utility Model Content
[0004] The purpose of this invention is to provide a composting aeration device to overcome the aforementioned deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A composting aeration device, comprising:
[0007] An aeration box with an internal cavity has several ventilation holes on the top and an aeration pipe on the side for connecting to an external air supply device.
[0008] And a barrier, which is set around the top of the aeration box, and the space enclosed by the barrier and the top of the aeration box is used to place materials.
[0009] Optionally, angle irons are fixedly installed at the four corners of the top of the aeration box, and the enclosure is supported and limited by the angle irons.
[0010] Optionally, reinforcing ribs are provided on the outer sides of both sides of the angle iron.
[0011] Optionally, the aeration box has open ends, and sealing plates are connected to the open ends by fasteners. The aeration box has a collection tray that can be taken out and put in through the open ends, and the height of the collection tray is less than the height of the cavity inside the aeration box.
[0012] Optionally, a sealing strip is provided on the contact surface between the sealing plate and the aeration box.
[0013] Optionally, the aeration box has a support plate parallel to the sealing plate inside, which divides the inside of the box into two cavities, each of which is provided with at least one aeration pipe.
[0014] Optionally, two collection trays are placed side by side in each of the cavities.
[0015] Optionally, a limiting strip is provided between the two collection trays. The limiting strip is fixedly connected to the inner bottom of the aeration box, and the height of the limiting strip is equal to the height of the collection tray.
[0016] Optionally, the diameter of the vent is 3mm-5mm, and the center distance between adjacent vents is twice the diameter of the vent.
[0017] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, compost material is placed in the space enclosed by the enclosure and the top of the aeration box. Air is supplied to the interior of the aeration box through the aeration pipe on the side of the aeration box, and the air enters the interior of the material through the ventilation holes set on the top of the aeration box, thereby forming aerobic fermentation. In this method, because the top of the aeration box is covered with ventilation holes, the aeration is more uniform. Moreover, because the aeration pipe is set on the side of the aeration box, it is avoided from being blocked by the material, ensuring the aeration effect and preventing uneven aeration and blockage of the aeration pipe from affecting the rapid maturation and quality stability of the compost.

[0025] refer to Figures 1-4 A composting aeration device includes an aeration box 1 and a enclosure 3. The enclosure 3 is fixedly installed around the top of the aeration box 1. The space enclosed by the enclosure 3 and the top of the aeration box 1 is used to place materials. It is easy to understand that the space enclosed by the enclosure 3 and the aeration box 1 acts as a fermentation container. In actual application, the top of the enclosure 3 should be covered with a film, that is, the film should cover the composting material within the space enclosed by the enclosure 3 and the top of the aeration box 1.
[0026] As an alternative, the enclosure 3 is fixed in the following way in this embodiment: angle irons 8 are fixedly installed at the four corners of the top of the aeration box 1. Specifically, the angle irons 8 are welded to the aeration box 1. The enclosure 3 is supported and limited by the angle irons 8. That is, the enclosure 3 is placed inside the angle irons 8, and the angle irons 8 limit its position and support it to prevent it from falling outward. In practical applications, the enclosure 3 can be made of wood, steel plate, etc. The enclosure 3 can be a whole, or it can be four pieces, one on each side of the aeration box 1.
[0027] Furthermore, in this embodiment, reinforcing ribs 9 are provided on the outer sides of both sides of the angle iron. Specifically, the reinforcing ribs 9 are welded to both the angle iron 8 and the aeration box 1. The reinforcing ribs 9 prevent the material from bending the angle iron 8, ensuring effective support for the angle iron 8.
[0028] The aeration box 1 has an internal cavity, and the top of the aeration box 1 is provided with several ventilation holes 101. Alternatively, the ventilation holes are arranged in a rectangular array and cover the top of the aeration box 1. The diameter of the ventilation holes 101 is 3mm-5mm, and the center distance between adjacent ventilation holes 101 is twice the diameter of the ventilation holes 101. In practical applications, the diameter of the ventilation holes 101 can be selected as 3mm, 4mm and 5mm, and the center distance between adjacent ventilation holes 101 is 6mm, 8mm and 10mm respectively. Preferably, the diameter of the ventilation holes 101 is 4mm and the center distance between adjacent ventilation holes 101 is 8mm.
[0029] The aeration box 1 has an aeration pipe 2 on its side. In practical applications, the aeration pipe 2 is connected to an external air supply device (not shown in the figure). The air supply device supplies air to the aeration box 1, and the air enters the material through the vent holes 101, thereby achieving aerobic fermentation. In this method, because the top of the aeration box 1 is covered with vent holes 101, the aeration is more uniform. Moreover, because the aeration pipe 2 is located on the side of the aeration box 1, it is prevented from being blocked by the material, ensuring the aeration effect and avoiding the impact of uneven aeration and blockage of the aeration pipe 2 on the rapid maturation and quality stability of the compost.
[0030] It is worth noting that since the material is supported by the top of the aeration box 1, and the top of the aeration box 1 has a ventilation hole 101, even if the ventilation hole 101 is small, some material will still fall into the aeration box 1 in actual application. Therefore, the following improvements have been made in this embodiment to solve this problem.
[0031] The aeration box 1 has open ends, and a sealing plate 4 is connected to the open ends by fasteners (preferably screws). The sealing plate 4 ensures that the interior of the aeration box 1 is a sealed cavity, preventing the supplied air from leaking out. Furthermore, a sealing strip is provided on the contact surface between the sealing plate 4 and the aeration box 1 to ensure a sealing effect. Specifically, a sealing groove is provided on the end face of the open end of the aeration box 1, and the sealing strip is placed in the sealing groove.
[0032] The aeration box 1 has a collection tray 6 inside, which can be accessed through an open opening. The height of the collection tray 6 is less than the height of the internal cavity of the aeration box 1. It should also be understood that the aeration pipe 2 should be located above the collection tray 6, meaning the height of the aeration pipe 2 is higher than the top of the collection tray 6. The collection tray 6 is a box-shaped structure with an open top. In practical applications, the collection tray 6 can collect materials that fall into the aeration box 1. The collected materials can then be removed and cleaned by disassembling the sealing plate 4.
[0033] refer to Figure 5 and Figure 6 The aeration box 1 has a support plate 5 parallel to the sealing plate 4 inside. It is worth noting that the support plate 5 can support the top of the aeration box 1, ensuring effective support for the material and avoiding problems such as the top of the aeration box 1 collapsing; on the other hand, it can facilitate the placement of the collection tray 6 on both sides of the support plate 5, which can reduce the length of the collection tray 6.
[0034] The support plate 5 divides the interior of the box into two chambers, each of which is equipped with at least one aeration pipe 2, ensuring that each chamber can be supplied with air. Furthermore, two collection trays 6 are placed side-by-side in each chamber, with the width of each collection tray 6 reduced for easy placement and removal.
[0035] Based on the two collection trays 6 placed side by side in each cavity, a limiting strip 7 is provided between the two collection trays 6. The height of the limiting strip 7 is equal to the height of the collection tray 6. The limiting strip 7 is fixedly connected to the inner bottom of the aeration box 1. As can be easily understood, the setting of the limiting strip 7 is to better restrict the position of the collection trays 6 and facilitate their removal and placement.
[0036] Furthermore, it is easy to understand that, based on the above, the aeration box 1 should not have ventilation holes 101 at the position corresponding to the support plate 5 and the position corresponding to the limit strip 7. The ventilation holes 101 should be located at the position covered by the collection tray 6 to prevent materials from falling outside the collection tray 6.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
