Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to a sludge composting aeration device. Background Technology

[0002] Sludge composting is a process that transforms sludge into stable organic fertilizer through microbial fermentation, and it holds significant importance in environmental protection and resource utilization. The aeration device is the core equipment in the sludge composting process. It provides forced ventilation to the compost pile, maintaining an aerobic fermentation environment, preventing localized anaerobic conditions or overheating, and ensuring fermentation efficiency. Existing sludge composting aeration devices typically consist of forced ventilation equipment and air supply pipelines. These pipelines are fixed to the ground. After fermentation, the pipelines buried under the compost pile become physical obstacles, hindering the normal operation of equipment such as loaders and turners, thus affecting production efficiency. Furthermore, mechanical equipment operation can easily cause scratches and compression damage to the pipelines, affecting the operational stability and service life of the aeration device. In addition, because the distribution of the air supply pipelines is fixed, adjustments are very inconvenient, and the compost piles can only be constructed according to specific dimensions, resulting in poor flexibility and applicability. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a sludge composting aeration device, which delivers air to the material pile through an air delivery hose. After fermentation is completed, the air delivery hose can be pulled out to avoid hindering the operation of mechanical equipment, thereby improving production efficiency.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A sludge composting aeration device includes a forced ventilation device, a roller, a power unit, and a baffle plate mounted on the machine body. The roller is hollow inside, with its central axis extending horizontally and driven by the power unit to rotate around the central axis. One end of the roller is connected to a rotary joint, and the inner cavity of the roller is connected to the output end of the forced ventilation device via the rotary joint. The roller has several winding zones along its axial direction, and each winding zone has a corresponding air supply hose. One end of the air supply hose is fixedly connected to the side wall of the roller and communicates with the inner cavity of the roller, while the other end is a free end. Exhaust holes are evenly distributed on the wall of the air supply hose. The baffle plate is located on one side of the roller and has through holes corresponding to the winding zones. The free end of the air supply hose passes through the corresponding through holes.

[0006] In a preferred embodiment, adjacent winding areas are separated by an isolation disc, which is annular and fitted onto the roller.

[0007] In a preferred embodiment, the body is equipped with a guide wheel assembly for guiding and limiting the gas delivery hose.

[0008] In a preferred embodiment, the power unit and the baffle plate are located on opposite sides of the roller, and the power unit and the forced ventilation device are located on the same side of the roller.

[0009] In a preferred embodiment, the wall of the gas delivery hose is made of an elastic material, and the vent is a straight or cross-shaped cut on the side wall of the gas delivery hose.

[0010] In a preferred embodiment, a sheath is installed on the through hole of the baffle plate, and the air supply hose passes through the sheath and the two are slidably engaged.

[0011] In a preferred embodiment, the gas delivery hose is provided with tensile reinforcing ribs.

[0012] Compared with the prior art, the sludge composting aeration device of this utility model has the following beneficial technical effects:

[0013] 1. After fermentation is complete, the air delivery hose is wound up using rollers and can be pulled out of the material pile.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1-4 As shown, this embodiment discloses a sludge composting aeration device, which is equipped with a forced ventilation device 1, a roller 5, a power device 3 and a baffle plate 9 on the body 2.

[0026] The main body of the roller 5 is cylindrical with a hollow interior. Both ends are rotatably connected to two supports 11 fixed to the machine body 2, allowing the central axis of the roller 5 to extend horizontally and rotate around it. The power unit 3 is fixed to the machine body 2 and connected to the roller 5 via a transmission connection to drive its rotation and adjust its rotation direction. A rotary joint 10 is installed at one end of the roller 5, and the inner cavity of the roller 5 is connected to the output end of the forced ventilation device 1 via the rotary joint 10. During the rotation of the roller 5, the forced ventilation device 1 remains connected to the interior of the roller 5 via the rotary joint 10. The forced ventilation device 1 is fixed to the machine body 2 and consists of a motor and a fan; the airflow can be adjusted as needed. The roller 5 is divided axially into several... In the dry winding area, each winding area is provided with a corresponding air supply hose 8. One end of the air supply hose 8 is fixedly connected to the side wall of the roller 5, and this end of the air supply hose 8 communicates with the inner cavity of the roller 5. The other end of the air supply hose 8 is a free end and a blind end, i.e., a closed structure is adopted. Exhaust holes 7 are evenly opened on the tube wall of the air supply hose 8. Thus, by rotating the roller 5, the air supply hose 8 can be unwound or wound. When the forced ventilation device 1 is working, the air is dispersed into each air supply hose 8 through the inner cavity of the roller 5 and finally evenly discharged through the exhaust holes 7. The baffle plate 9 is fixed on the machine body 2 and located on one side of the roller 5. The baffle plate 9 has the same number of through holes as the winding area and they correspond one-to-one. The free end of the air supply hose 8 passes through the corresponding through hole.

[0027] like Figure 3 , Figure 5 As shown, this sludge composting aeration device is suitable for sludge composting processes and is placed at one end of the material pile during use. Before stacking, the power unit 3 drives the roller 5 to rotate, thereby unwinding the air supply hose 8. Simultaneously, the free end of the air supply hose 8 is pulled to move, laying the air supply hose 8 on the ground of the stacking area. The spacing of the air supply hoses is adjusted according to the size of the material pile. Afterward, the treated sludge material is stacked into shape. During the fermentation cycle, the forced ventilation device 1 introduces fresh air into the material pile to provide sufficient oxygen for fermentation, preventing localized anaerobic or overheating and achieving aeration. After fermentation is complete, the power unit 3 drives the roller 5 to... The air supply hose 8 is wound up, pulled out of the material pile and wrapped around the roller 5. During this process, the baffle plate 9 can prevent the material from moving with the air supply hose 8. After the air supply hose 8 is completely pulled out of the material pile, there will be no obstructions in the material pile. Mechanical equipment can be used to load or turn the fermented material, which significantly improves the work efficiency and avoids damage to the aeration device components during mechanical equipment operation. If it is necessary to turn the pile for secondary fermentation, the above method can be used to rebuild the pile and lay the air supply hose 8 at the bottom of the material pile again.

[0028] This sludge composting aeration device delivers the air required for composting through a flexible air delivery hose 8. The placement and spacing of the air delivery hose 8 are flexibly adjustable, making this sludge composting aeration device suitable for material stacks of different sizes, thus exhibiting good applicability.

[0029] After the air delivery hose 8 is wound up, the overall structure of this sludge composting aeration device is small and compact, and the placement position can be flexibly adjusted according to the change of the stacking position.

[0030] like Figure 1 , Figure 2 , Figure 4 As shown, in this sludge composting aeration device, adjacent winding zones are separated by an isolation disc 4, which is annular and fitted onto the roller 5. Under the limiting effect of the isolation disc 4, each air supply hose 8 is wound and unwound in its corresponding winding zone without interfering with each other, thus avoiding entanglement and reduced operational stability.

[0031] like Figure 1 , Figure 2 , Figure 4 As shown, in this sludge composting aeration device, the machine body 2 is equipped with a guide wheel assembly 6 consisting of multiple guide wheels. The guide wheel assembly 6 is used to guide and limit the air delivery hose 8, ensuring that the roller 5 can wind and unwind the air delivery hose 8 more effortlessly and smoothly. At the same time, it effectively reduces the tension on the air delivery hose 8 during winding and extends the service life of the air delivery hose 8. Specifically, the guide wheel assembly 6 is set between the roller 5 and the baffle plate 9 to guide the air delivery hose 8 to move smoothly through the through hole on the baffle plate 9.

[0032] like Figure 1 , Figure 2 , Figure 4 As shown, in this sludge composting aeration device, the power unit 3 and the baffle plate 9 are located on opposite sides of the roller 5, and the power unit 3 and the forced ventilation device 1 are located on the same side of the roller 5, thereby optimizing the structural layout of the above components and improving the overall compactness of the structure.

[0033] In this sludge composting aeration device, the exhaust port 7 is located on the wall of the air supply hose 8 so that air can be evenly discharged into the fermentation material. Therefore, the exhaust port 7 can adopt a conventional hole design, such as a round hole or a square hole. Figure 6As shown, in a preferred embodiment, the wall of the air supply hose 8 is made of an elastic material, and the vent 7 is a straight or cross-shaped slit opened on the side wall of the air supply hose 8. This gives the vent 7 a self-closing function. During forced ventilation, the internal air pressure of the air supply hose 8 is relatively high, which can drive the slit-shaped vent 7 to open and allow air to be discharged to the outside. When forced ventilation is not performed, the vent 7 can automatically return to the closed state, thereby preventing material or moisture seeping from the material from entering the air supply hose 8 and affecting the aeration effect. In addition, based on the above design, when the vent 7 automatically returns to the closed state, the outer wall of the air supply hose 8 will be smoother, making it easier to pull the air supply hose 8 out of the material pile, reducing the tensile strength requirements of the air supply hose 8 and the workload of the power unit.

[0034] like Figure 1 , Figure 4 As shown, in this sludge composting aeration device, a protective sleeve 12 is installed on the through hole of the baffle plate 9, and the air conveying hose 8 passes through the protective sleeve 12 and the two are slidably engaged. On the one hand, the protective sleeve 12 can achieve good guiding and protective functions, allowing the air conveying hose 8 to pass smoothly through the baffle plate 9, reducing wear and stress. On the other hand, the protective sleeve 12 can effectively scrape off the material adhering to the outside of the air conveying hose 8, improve the material blocking effect of the baffle plate 9, and prevent material from entering the other side of the baffle plate 9, so as to ensure the stability of the device operation.

[0035] like Figure 6 As shown, in this sludge composting aeration device, the air supply hose 8 is provided with tensile reinforcing ribs 13, which can ensure that the air supply hose 8 has good bending ability as a whole, good elastic deformation performance in the radial direction, and high tensile strength in the axial direction, so as to improve the multiple performance requirements of the air supply hose 8 of this sludge composting aeration device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
