[0028] Example

[0029] like Figure 1-5 As shown, a static straw composting device proposed in one embodiment of the utility model comprises a composting box 1, wherein the composting box 1 is fixedly mounted on a bracket 2, the bracket 2 is fixedly supported, the composting box 1 is hingedly connected with a flip cover plate 3 by hinge rotation, a ventilation pipe 4 is installed inside the composting box 1, a ventilation hole 5 is arranged at the bottom of the ventilation pipe 4, a side wall of the composting box 1 covers an air collecting hood 6, the air collecting hood 6 is connected to the ventilation pipe 4, an electric heating pipe 7 is inlaid and installed inside the air collecting hood 6, the air collecting hood 6 is connected to the ventilation pipe 8, the bottom of the composting box 1 is connected to an interface frame 9, a slide groove 10 is arranged inside the interface frame 9, a slide plate 11 is slidably connected inside the slide groove 10, and a handle 12 is fixedly connected to one end of the slide plate 11;

[0030] Composting box 1: It is the main storage space for the entire composting process and provides a place for straw to undergo composting reaction.

[0031] Bracket 2: used for fixing and supporting the compost bin 1 to ensure the stability and safety of the compost bin 1.

[0032] The flap plate 3 is rotatably connected to the compost bin 1 through a hinge, so that it is convenient to open and close, and convenient to put in straw and observe the composting situation.

[0033] Ventilation pipe 4: installed inside the compost bin 1, with ventilation holes 5 at the bottom. Allow air to evenly enter the compost bin 1, provide sufficient oxygen for the compost, and promote the decomposition of microorganisms.

[0034] Ventilation hole 5: Disperses the air in ventilation pipe 4 evenly into the compost.

[0035] The air collecting hood 6 is covered on the side wall of the composting box 1 and has a hollow structure inside, and collects and guides air into the ventilation pipe 4.

[0036] Electric heating tube 7: embedded and installed inside the wind collecting cover 6. Provides additional heat to the composting environment when needed, adjusts the composting temperature, and accelerates the composting process.

[0037] Air duct 8: connected to the air collecting hood 6, and provided with an electric control valve to control the inlet and outlet and flow rate of air.

[0038] Interface box 9: Located at the bottom of the composting box 1 and connected to the composting box 1. Used to discharge the composted product.

[0039] The slide 10 and the slide 11: The opening and closing of the interface frame 9 is controlled by sliding the slide 11, so as to control the discharge.

[0040] Centrifugal fan: As a fan device, it is connected to the wind hood 6 through the air duct 8. It provides the power of air induction and blowing to ensure the normal operation of the ventilation system.

[0041] Working principle:

[0042] First, the flap plate 3 is opened, straw is put into the compost box 1 with a bucket structure, and then the flap plate 3 is closed.

[0043] The centrifugal fan is started to blow or inhale air to the air collecting hood 6 through the air duct 8. When the fan blows air, air enters the air collecting hood 6. If the compost needs additional temperature adjustment, the electric heating tube 7 in the air collecting hood 6 can be powered on to heat the air.

[0044] The heated air or air at room temperature enters the ventilation pipe 4 through the air collecting hood 6. Since the ventilation pipe 4 is arranged in a triangular shape and has ventilation holes 5 at the bottom, the air can be evenly distributed in the straw in the composting box 1, providing sufficient oxygen for the decomposition activities of microorganisms.

[0045] During the composting process, the generated materials can be discharged through the interface frame 9 at the bottom of the composting box 1. Pulling the handle 12 causes the slide plate 11 to slide in the slide groove 10, thereby controlling the opening and closing of the interface frame 9 to achieve discharge control of the compost product.

[0046] The electric control valve on the air duct 8 can adjust the inlet and outlet and flow rate of air to adapt to different composting stages and needs.

[0047] The entire device creates suitable conditions for straw composting through the coordinated operation of various components, promoting the decomposition and transformation of straw.

[0048] like Figure 1As shown, in some embodiments, the compost box 1 is a bucket-type structure; the bucket-type structure is large at the top and small at the bottom, which is conducive to the natural accumulation of materials, so that the straw can be composted more concentratedly. This structure can increase the stacking density of the compost material and improve the space utilization rate. At the same time, the liquid generated during the composting process can naturally flow to the bottom under the action of gravity, which is convenient for subsequent processing and discharge. Moreover, the bucket-type structure is relatively stable and can withstand the pressure of the materials during the composting process, ensuring the stability and safety of the compost box 1.

[0049] like Figure 4 As shown, in some embodiments, the ventilation pipe 4 is arranged in a triangular shape, and the ventilation hole 5 is arranged at the bottom of the triangular ventilation pipe 4; the triangular structure is relatively stable, can maintain good support and fixation in the compost bin 1, and is not easy to deform. The ventilation hole 5 is arranged at the bottom, so that the air blown out from the ventilation pipe 4 can directly act on the bottom layer of the compost material. This helps the air to diffuse more evenly in the compost material, avoiding the situation where the upper layer of the material is well ventilated while the bottom layer of the material is lack of oxygen.

[0050] like Figure 5 As shown, in some embodiments, the interior of the air collecting hood 6 is a hollow structure; first, the hollow structure can provide enough space to accommodate and guide the air flow. It can collect air from the fan and guide it smoothly to the ventilation pipe 4, reducing the resistance and turbulence of the air flow, and ensuring that the air can smoothly enter the composting box 1.

[0051] Secondly, the hollow air collecting hood 6 can play a certain buffering role. When the air flow rate blown out by the fan is unstable, the air collecting hood 6 can balance and adjust the air flow, making the air entering the ventilation pipe 4 more uniform and stable, thereby providing continuous and stable ventilation conditions for composting.

[0052] For example, if the fan blows out a large amount of air at a certain moment, if there is no hollow air collecting hood 6 to buffer and adjust, it may cause excessive ventilation in some parts and insufficient ventilation in other parts. However, due to the hollow structure of the air collecting hood 6, it can temporarily store excess air and gradually distribute it evenly to the ventilation pipe 4, thus avoiding this imbalance.

[0053] In addition, the hollow structure is relatively light and will not add too much weight to the entire device. It is also convenient for installing and maintaining components such as the internal electric heating tube 7.

[0054] In this embodiment, an electric control valve is provided on the air duct 8, and the air duct 8 is connected to a fan device; the electric control valve can accurately adjust the flow rate of air in the air duct 8. By controlling the opening of the valve, the amount of air entering the composting box 1 can be flexibly changed according to different stages of composting and actual needs.

[0055] For example, in the early stage of composting, microbial activity is relatively vigorous and requires more oxygen supply. At this time, the electric control valve can be opened to increase ventilation. In the later stage of composting, microbial activity is relatively slow and the demand for oxygen is reduced. The valve can be appropriately adjusted to reduce ventilation.

[0056] This arrangement can also conveniently control the pressure in the compost bin 1. When it is necessary to maintain a certain positive pressure or negative pressure environment to promote a specific composting reaction, this can be achieved by adjusting the electrically controlled valve.

[0057] In addition, if an abnormal situation occurs, such as the temperature in the composting box 1 is too high or the concentration of harmful gases exceeds the standard, the electric control valve can be quickly closed, ventilation can be suspended, and corresponding treatment can be carried out.

[0058] In short, the setting of the electric control valve makes the operation of the entire ventilation system more flexible and controllable, which helps to improve the effect and quality of composting.

[0059] In this embodiment, the fan device is a centrifugal fan, which is used for both air induction and blowing. The centrifugal fan has a high air pressure and air volume output capacity. In the blowing mode, it can forcefully push air into the ventilation system, ensuring that sufficient fresh air enters the composting box 1, providing sufficient oxygen for the microorganisms, and promoting the rapid progress of composting.

[0060] For example, when the compost bin 1 is large or there are many compost materials, the powerful blowing ability of the centrifugal fan can overcome the pipe resistance and material resistance and deliver the air evenly to every corner.

[0061] In the induced draft mode, the centrifugal fan can effectively extract moisture, odor and excess heat generated during the composting process, keeping the composting environment relatively dry and at a suitable temperature, which is beneficial to improving the quality of the compost.

[0062] For example, under hot and humid weather conditions, the hot and humid air in the composting box 1 can be discharged in time through the air-inducing effect of the centrifugal fan, thereby avoiding overheating and corruption during the composting process.

[0063] In addition, centrifugal fans operate relatively stably, make less noise, and can adapt to different working conditions. They can work reliably for a long time and meet the continuous ventilation needs of the composting process.

[0064] like Figure 3 As shown, in some embodiments, the chute 10 is arranged in the middle of the interface frame 9, and engages with the sliding slide plate 11; this design can make the slide plate 11 more stable and balanced when sliding. Since the chute 10 is located in the middle of the interface frame 9, the slide plate 11 is subjected to a more uniform force distribution when bearing the pressure of the compost material, and is not prone to tilting or jamming, thereby ensuring the smoothness of the slide plate 11.

[0065] like Figure 4 As shown, in some embodiments, the ventilation pipe 4 is a stainless steel pipe; stainless steel has good corrosion resistance and can be in contact with a humid environment containing certain chemicals for a long time during the composting process without being easily rusted or damaged, thereby extending the service life of the ventilation pipe 4.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
