Description

[0001] The original basis of this divisional application is the patent application with application number 202310186028.8, application date March 1, 2023, and invention name “A system and method for composting garden waste”. Technical Field

[0002] The invention relates to the technical field of gardening, and in particular to a waste composting device and a control center thereof. Background Art

[0003] Dead branches, fallen leaves and weeds in gardens are called garden waste. With the rapid development of ecological cities, the amount of garden waste is increasing. If garden waste is not handled properly, it will not only affect the beauty of the city, but also may cause pollution to the atmosphere, water bodies and soil, thus affecting the health of urban residents and the construction of ecological cities. With the rapid advancement of my country's gardening and greening industry, the area of ​​urban greening has continued to increase, and the amount of garden waste generated has also increased. Traditional landfilling and incineration not only pollute the environment, but also cause waste of resources, hindering the construction of conservation-oriented gardens and failing to meet the requirements of ecological civilization development. Therefore, prohibiting incineration and landfilling and taking scientific and reasonable measures to integrate and utilize garden waste for the second time is an inevitable way to take the path of sustainable development.

[0004] In the related technology, composting fermentation equipment is usually used in combination with garden waste composting fermentation technology to convert garden waste into biological organic fertilizer, which not only solves the problem of garden waste disposal, but also the application of biological organic fertilizer into the soil can improve the physical structure of the soil, improve soil compaction, retain water and fertilizer, and improve soil fertility, thereby promoting the growth of plant roots; in addition, it can also increase the number of beneficial microorganisms in the soil, kill harmful bacteria in the soil, etc.

[0005] There are two methods of garden composting: outdoor and indoor. A Chinese patent with patent publication number CN1104400C discloses a composting system, which includes an area for placing compostable materials; compostable materials located in this area; and a windproof cover or structure, which is preferably attached to and covers the compostable materials. The cover or structure defines the environment in which the composting occurs, and the environmental conditions are controlled to accelerate the composting process. The system provides a system and method suitable for outdoor composting, in which the composting process is uncontrollable due to the lack of monitoring.

[0006] The Chinese patent with patent announcement number CN106680046A discloses a gas detection device for organic fertilizer composting, which includes a gas collection device, a gas impurity and moisture filtering device and a gas online detection device; the gas collection device is a bottomless box with two small holes on the upper surface of the box, and a pipe is inserted in each of the two small holes, one of which is located above the box and connected to the outside air; one end of the other pipe extends above the organic fertilizer pile, and the other end is connected to the gas impurity and moisture filtering device and the gas online detection device; the gas impurity and moisture filtering device filters the volatile gas generated by the organic fertilizer composting, and the gas online detection device continuously detects the filtered volatile gas and saves the detection data at the same time. Relatively accurate information on fertilizer fermentation can be obtained by detecting the gas data in the composting environment, and corresponding adjustment conditions can be generated based on this.

[0007] During the composting process, due to the large volume of fertilizer accumulation, the physical properties of the internal space of the accumulated fertilizer will change due to microbial activities such as decomposition and fermentation, resulting in a non-steady-state material transfer process in its internal space. It is also difficult for various reaction conditions that need to be controlled in the internal space of the fertilizer to be consistent with the external environment, such as humidity, oxygen content or temperature.

[0008] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0009] In the prior art, the accumulated garden waste is considered as a whole and monitored. However, in the actual composting process, the volume of the composting container for accommodating the waste is generally very large, and the waste accumulated in the container will produce new substances and energy while transferring substances and energy. For example, microorganisms will carry out life activities in the waste and produce gases such as ammonia and carbon dioxide and generate heat. Since the internal space of the accumulated waste is not a stable biological environment, the substances and energy (for example, heat, oxygen) in the internal space of the waste are an unstable transfer process. In this process, once the temperature, oxygen content or humidity exceeds the expected range, it is very likely to cause a large number of deaths of microorganisms inside it, thereby reducing the efficiency of garden waste composting.

[0010] In view of the deficiencies of the prior art, the present invention provides a garden waste composting system, which includes at least a fertilizer reactor, a control center, a regulating unit at least arranged in at least two areas of the fertilizer reactor, a first detection unit capable of actually obtaining the temperature of the fertilizer reactor in at least two areas, and a second detection unit capable of actually obtaining the gas C / N ratio of the fertilizer reactor in at least two areas. The control center can divide the fertilizer reactor into a plurality of independent regional reaction spaces based on the spatial distribution of the fertilizer reactor, and generate a preset first range based on the type of garden waste; based on the data provided by the first detection unit and the second detection unit, the control center can at least generate instructions related to gas and / or temperature regulation when the data exceeds the first range so that the gas control unit adjusts the gas and / or temperature of the regional reaction space.

[0011] Beneficial effects of this technical solution:

[0012] (1) A fertilizer reactor with an unstable material conduction process is divided into a plurality of local spaces within a controllable range, so that the heat and oxygen content of each local space are monitored, and each data that needs to be adjusted is fed back in time based on the monitoring data, so that each part in the fertilizer reactor is heated evenly and has a uniform oxygen content, ensuring that microorganisms can obtain growth space in the fertilizer reactor, thereby achieving the purpose of efficiently composting waste in the fertilizer reactor.

[0013] (2) Based on the fact that heat and gas can be transferred in a static fertilizer reactor (in a state without external force to turn it over), and that heat and gas can serve as important indicators of whether the fertilizer reactor is in a healthy state, the present invention can set a first detection unit and a second detection unit in different local areas of the fertilizer reactor. When the data obtained by the first detection unit and the second detection unit are not within the preset first range, it indicates that the temperature and / or gas content (oxygen content or harmful gas content) of the current environment do not meet the survival conditions of microorganisms. Based on this judgment, the system can automatically select the adjustment unit of the corresponding area to adjust the temperature and / or oxygen content of the area, so that the harmful gas in the area can be homogenized by oxygen and maintained within a temperature range favorable for the growth of microorganisms.

[0014] (3) Since gas and heat have a conductive effect, the heat or gas generated by the regulating equipment set at a single location will affect the composting process of waste at other locations. The present invention sets the actual control range of the fertilizer reactor to multiple controllable ranges, so that part of the space of the fertilizer reactor is regulated while other spaces are not affected.

[0015] According to a preferred embodiment, the fertilizer reactor is divided into a plurality of independent regional reaction spaces based on the spatial distribution of the fertilizer reactor, which means that at the initial time, the space where the composting material is placed is set as an independent regional reaction space, and the space in the fertilizer reactor where the composting material is not placed (i.e., the space above the composting material in the fertilizer reactor) is set as an independent regional reaction space. Preferably, the fertilizer reactor is divided into at least two areas, namely, an empty area in the fertilizer reactor and an area where the material is placed.

[0016] According to a preferred embodiment, since the heat conduction effect of the heat conducting rod will weaken with the distance, the number of independent regional reaction spaces can be divided based on the volume of the material piled in the fertilizer reactor. For example, the material is fallen leaves. Through simple tests, the user can obtain the farthest effective distance that a 300w heat conducting rod can make the surrounding environment reach 26°C within 10 minutes when inserted into the material pile, and use this distance as the length of the independent regional reaction space. For example, the independent regional reaction space is a cube centered on the heat conducting rod, and the farthest effective distance is half the side length of the cube.

[0017] According to a preferred embodiment, the system further comprises a third detection unit. The third detection unit can detect whether the material in the fertilizer reactor is agglomerated.

[0018] According to a preferred embodiment, the agglomeration detected by the third detection unit refers to:

[0019] The substances in the fermentation process adhere to each other due to environmental factors, forming a block structure with a density higher than the surrounding density. Preferably, the volume of the block structure can be between 5 and 55 cm 3 .

[0020] According to a preferred embodiment, the system further includes storing data of agglomeration detected by the third detection unit corresponding to different types of biological matrices. The agglomeration requirements detected by the third detection unit can be retrieved from a preset database and are retrieved based at least on the type of biological matrix. For example, the agglomeration size of wheat bran is 5 cm 3 .

[0021] When agglomerated substances that meet the volume requirements appear in the corresponding area, the third detection unit can detect the agglomerated substances and confirm the spatial position of the substances. The control center can set the spatial range of the diameter μ centered on the spatial position as an independent regional reaction space based on the spatial position of the substance, that is, at the initial time, the independent regional reaction space can be divided based on the distribution area of ​​the heat conducting rod or the distribution area of ​​the substance in the fertilizer reactor. With the generation of agglomerated substances during the fermentation of the substances, the independent regional reaction space can also include a spatial range of the diameter μ centered on the agglomerated substances. Preferably, μ is dynamically changed based on the needs of the user. For example, when the system is in the dry and cold north and the fertilizer reactor is storing garden waste, μ can be 20 to 30 cm. Particularly preferably, μ can be 25 cm. Preferably, when the system is in the south with a relative humidity of 75% and a temperature of 4°C and the fertilizer reactor is storing distiller's grains or bran, μ is 10 to 15 cm.

[0022] The present application has found that dynamically dividing the regional reaction space according to the detected agglomerate size is an advantageous method that can accurately control whether there are unexpected interactions between regions under the condition of the presence of unstable products such as bioreaction gas and / or temperature. When the presence of agglomeration areas in the substance is found based on the detection equipment, it means that the biological reaction and biological aggregation of the fermenting substance at this location have reached a local peak, which is representative. Compared with the problem of uneven distribution of actual composting results caused by the traditional scheme for the overall environmental control of the composting area, this scheme can obtain more homogeneous composting results.

[0023] According to a preferred embodiment, the gas control unit is provided with gas pipe assemblies capable of extracting and / or inletting gas at the top, bottom and middle part of the fertilizer reactor.

[0024] The fertilizer reactor in the present invention refers to a waste reactor.

[0025] According to a preferred embodiment, the conditioning unit comprises at least a second component capable of inputting / outputting gas and a first component capable of providing heat.

[0026] When the first detection unit detects that the temperature of the corresponding area is lower than the lower limit of the preset first range, and the second detection unit detects that the C / N ratio of the gas in the corresponding area is within the preset first range, the first component can provide temperature for the corresponding area until the temperature of the area reaches the preset first range. The number of microorganisms in the fertilizer reactor in this state is insufficient and the activeness of life activities is not high, so the oxygen consumption is low. The control center can prompt the operator to supplement the exogenous reaction microorganisms while increasing the temperature of the area. Preferably, when the first detection unit detects that the temperature of the corresponding area is lower than the lower limit of the preset first range, and the second detection unit detects that the C / N ratio of the gas in the corresponding area is within the preset first range, the system can also detect the humidity in the environment. When the humidity is higher than the set range, since the fertilizer reactor is a sealed device, the means of increasing the temperature can be to fill the fertilizer reactor with dry and high-temperature air. When the humidity is lower than the set range, the means of heating can be external heating of the fertilizer reactor or inserting a heat conducting rod to increase the local temperature. In a sealed fertilizer reactor, inappropriate humidity is often caused by alternating hot and cold, so when the temperature changes, it is necessary to consider whether the humidity changes and causes the material to agglomerate. For example, when the material is wheat bran, when the humidity is higher than 60%, the heating means can be blowing in air with a humidity below 40%, which both increases the temperature and reduces the humidity. When the relative humidity of the environment reaches 50%, which meets the set range but the temperature does not reach the required range, the means of heating the air can automatically switch to a heat conducting rod or external heating means to prevent water vapor from being taken away from the fertilizer reactor. Preferably, the range of settings related to humidity can be between 40 and 80%. For example, when the material is fallen leaves, the range of settings related to humidity can be 60%.

[0027] When the second detection unit detects that the C / N ratio of the gas in the corresponding area is higher than the upper limit of the preset first range and the temperature is within the preset first range, the second component can provide oxygen at a first flow rate to the corresponding area. In this state, the number of microorganisms in the fertilizer reactor is sufficient and the life activities are active. It is foreseeable that the microorganisms in the corresponding area will consume excessive oxygen to maintain life activities during the temperature reduction process, so that the heat in the corresponding area accumulates. The oxygen at the first flow rate provided by the second component can continuously remove the exhaust gas from the corresponding area and allow the exhaust gas to take away the heat.

[0028] When the second detection unit detects that the C / N ratio of the gas in the corresponding area is higher than the upper limit of the preset first range and the temperature is higher than the upper limit of the preset first range, the second component can provide oxygen at a second flow rate to the corresponding area. The first flow rate is less than the second flow rate. In this state, the number of microorganisms in the fertilizer reactor is sufficient and the life activities are active. Oxygen is renewed to maintain the activity of microorganisms and a higher flow rate of oxygen gas is used to take heat away from the corresponding area, and the activeness of microbial life activities is reduced.

[0029] The present invention provides a garden waste composting method, which is implemented by a container with an inner liner bag inside, the garden waste is placed in a soft and liquid-impermeable inner liner bag in the container, the composting bottom frame in the inner liner bag accelerates the decomposition of the garden waste, the liquid is separated from the compost material, the supporting surface at the bottom of the inner liner bag is an inclined surface, and the liquid separated from the compost flows out along the inclined direction of the inclined surface. When the inner liner bag is filled, another inner liner bag can be replaced, and after being filled, it is transported to a storage point to wait for maturation.

[0030] The present invention provides a garden waste composting device, which includes a container. The container includes at least a supporting structure and a liner bag.

The position of the hole can be set at the position of the corresponding sleeved adjustment unit.

[0031] In the present invention, the production of garden waste compost is carried out in a closed liner bag. When the liner bag is filled, a new liner bag needs to be replaced. The filled liner bag contains both decomposed substances and undecomposed substances. The liner bag is transported to an appropriate storage point for placement and waiting for maturation. The closed liner bag can avoid the spread of pathogens. The liner bag containing the contents placed at the storage point is degradable. When the substances in the liner bag are completely decomposed, the liner bag itself is also degraded in the natural environment as the placement time increases, which is very friendly to the environment.

[0032] Preferably, the container is provided with at least one heat conducting rod inserted into the container, wherein the heat conducting rod can be inserted into different areas of the fertilizer reactor based on different height settings. Preferably, the system is provided with three heat conducting rods.

[0037] According to a preferred embodiment, the bottom of the supporting base is provided with a door, which can be opened and closed. When the container and the supporting base are lifted, the liner bag containing the contents can be lowered from the bottom of the supporting base to a storage point.

[0038] Garden waste is decomposed in a closed liner bag, which contains compost soil, decomposed materials and incompletely decomposed materials. When the liner bag is full, it is replaced. The filled liner bag can be easily transported to a suitable place to wait for maturation. At this time, you only need to put in a new liner bag to continue working. The liner bag includes a composting base.

[0039] The liner bag is closed but ventilated, and the compost is decomposed inside the liner bag, avoiding the spread of pathogens. The liner bag is closed, so there will be no liquid leakage during transportation and storage of the liner bag.

[0040] When the liner bag is completely filled, the container can be temporarily placed to wait for the contents in the liner bag to decompose and reduce the volume of the contents. The container can continue to be used, which can reduce the number of transportations and save time and effort. Alternatively, the filled liner bag can be directly removed and transported to the storage point to be matured, and replaced with a new liner bag with a composting base for use.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In this application, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0063] Example 1

[0064] The garden waste composting system provided by the present invention comprises a fertilizer reactor in which fallen leaves accounting for 90% by weight and sugar residue accounting for 10% by weight are piled up.

[0065] The preset first range of the second detection unit is 25:1 to 30:1. The preset first range of the first detection unit is 54 to 60°C.

[0066] When the first detection unit detects that the temperature of the corresponding area is 50°C and the second detection unit detects that the C / N ratio of the gas in the corresponding area is 25:1, the first component, namely the heat conducting rod 130, provides a heat source of 60°C. The first component stops supplying heat until the first detection unit of the corresponding area detects that the temperature of the corresponding area changes to 54°C.

[0067] Figure 1-2A garden waste composting device is provided, which includes a container 100. The container 100 includes at least a supporting structure 110 and a liner bag 120. The supporting structure 110 includes a supporting wall 111 for receiving a compostable substance and a supporting bottom 112 for supporting the liner bag 120. The liner bag 120 is arranged inside the container 100 to be filled with compost. The liner bag 120 is a sealing layer inside the container 100. The liner bag 120 is made of a soft and liquid-impermeable material. The liner bag 120 is made of a thin, naturally degradable plastic material. The supporting wall 111 is provided with a pin 111.2, and the supporting bottom 112 is provided with a hinge element 112.2, and the supporting wall 111 is connected to the hinge element 112.2 on the supporting bottom 112 through the pin 111.2. The supporting wall 111 can be rotated to a position perpendicular to the ground and in the vertical position, the adjacent supporting wall 111 can be locked by a locking member or other similar device to maintain the vertical position.

[0068] The supporting wall 111 is composed of a rigid plate structure. The near-ground end of the supporting wall 111 is rotatably mounted on the supporting base 112. The supporting wall 111 is mounted on the supporting base 112 to form a supporting structure 110 supporting the liner bag 120. The supporting wall 111 is arranged in the form of a rigid plate made of a lightweight material. The lightweight material can be plastic, plywood or concrete, etc. Preferably, the rigid plate constituting the supporting wall 111 is provided with a groove 111.1 or other similar structures. The design of the groove 111.1 enables the composting device to be stacked with a smaller gap in a manner of one device superimposed on another device during transportation, reducing the space required for stacking. Preferably, a molded element can also be arranged on the supporting base 112 and the supporting wall 111 so that the supporting wall 111 is connected to the supporting base 112. Preferably, the supporting base 112 has a side wall 112.3 protruding toward the far-ground end. The supporting wall 111 can stand vertically on the side wall 112.3 of the supporting base 112 or on the inner side of the side wall 112.3 without locking. Adjacent supporting walls 111 can be locked by using molding elements.

[0069] In this embodiment, the surface of the supporting bottom 112 supporting the liner bag 120 is a two-plane structure, and the two planes are inclined relative to each other to form an inclined surface 150. Since the liner bag 120 is made of a flexible material, when the bottom of the liner bag 120 contacts the inclined surface 150, the shape of the bottom of the liner bag 120 is adjusted to the same shape as the inclined surface 150. The design of the inclined surface 150 allows the liquid separated from the compost material to be transported along the inclined surface 150.

[0070] Preferably, the support base 112 is provided with rotatable and movable rollers 112.4. The design of the rollers 112.4 makes the support base 112 easy to adjust and manipulate, and allows the container 100 to be moved to a nearby storage point more easily. The rollers 112.4 allow the container 100 to move freely between different locations. The rollers 112.4 are arranged on a support rod 112.5 that protrudes slightly outward from the side edge of the support base 112.

[0071] Preferably, the inner liner bag 120 is provided with a composting frame, and the garden waste can be scattered into several small piles on the composting frame in the container 100, thereby increasing the total capacity of the container 100, and making the material to be decomposed roughly evenly distributed at the bottom of the inner liner bag 120, increasing the contact area between the material to be decomposed and the composting frame, and accelerating the decomposition of the material to be composted by the compost bed. In addition, the surface area of ​​the composting material is increased, which can contact more oxygen, which is conducive to the decomposition of the contents.

[0072] The container 100 is provided with at least one heat conducting rod 130 inserted into the container 100. Figure 7 shown.

[0073] The composting device includes a cover 200, which is mounted on the distal end of the supporting wall 111 to make the supporting wall 111 more stable, and the supporting wall 111 is mounted on the supporting bottom 112. The upper edge of the liner bag 120 is folded at the distal end edge of the supporting wall 111, and the folded portion of the liner bag 120 is pressed and held on the distal end edge of the supporting wall 111 by the cover 200. The cover 200 is provided with an opening 210 connected to the ventilation duct. Preferably, the cover 200 is provided with a plurality of openings 210.

[0074] The composting device is provided with a pipe seat 160 connected to the screening assembly 122. The screening assembly 122 is arranged inside the liner bag 120 and is parallel to the edge of the near-ground end of the inclined surface 150. The screening assembly 122 is connected to the discharge hole 121 of the liner bag 120. The screening assembly 122 and the inclined surface 150 are used to guide the liquid to flow out of the liner bag 120. Preferably, the screening assembly 122 includes a sieve tube with an orifice, and the sieve tube is connected to the pipe seat 160. The pipe seat 160 is provided with a closure so that the pipe seat 160 can be sealed to prevent the liquid in the liner bag 120 from overflowing. The pipe seat 160 can be connected to a storage tank containing nutrient solution.

[0075] As the contents filled in the liner bag 120 decompose, the volume of the solid matter therein will decrease. If the decomposed matter is transported at the same speed as the decomposition speed of the contents, it will take a certain amount of time to fill the liner bag 120, that is, one liner bag 120 can be used for a longer time.

[0076] Preferably, a buckle 112.31 is provided on the side wall 112.3 of the support base 112. The buckle 112.31 can be provided on any side of the side wall 112.3 of the support base 112. A box door 112.1 is provided at the bottom of the support base 112, and the box door 112.1 can be opened and closed, such as Figure 3 As shown, when the rope is connected to the buckle 112.31 and the supporting base 112 is lifted, due to the weight of the liner bag 120, the box door 112.1 rotates toward the ground, thereby forming an opening at the supporting base 112, and the bottom of the supporting base 112 is opened, and the liner bag 120 containing the contents can be lowered from the bottom opening of the supporting base 112 to a designated position. The liner bag 120 has been sealed before being lowered, and a number of appropriate vents 123 can be provided. After the liner bag 120 is lowered, the container 100 does not need to be cleaned, because the sealing of the liner bag 120 can protect the container 100.

[0077] The liner bag 120 can ensure the sealing of the container 100, so the container 100 itself may not be completely sealed. The liner bag 120 supported by the rigid support wall 111 and the support bottom 112 can be made of a thin, cheap plastic material. The liner bag 120 made of a suitable plastic material can be naturally degraded when exposed to nature.

[0078] The garden waste is decomposed in the closed inner liner bag 120, which contains compost soil, decomposed materials and incompletely decomposed materials. When the inner liner bag 120 is full, it is replaced. The inner liner bag 120 filled with contents can be easily transported to a suitable place to wait for maturation. At this time, only a new inner liner bag 120 needs to be placed to continue working.

[0079] Preferably, a bottom frame is provided at the bottom of the container 100 .

[0080] When the liner bag 120 is filled, the entire container 100 on the roller 112.4 can be pulled and replaced with another container 100. Before replacement, the ventilation duct needs to be cut off. The used duct can be set as a telescopic duct with one duct nested in another duct for easy disconnection. The replaced container 100 has a new liner bag 120, and a new base frame of compost soil is set in the replaced container 100. The base frame can be supplemented with appropriate types of bacteria or insects.

[0081] An exhaust fan and a light bulb are provided in the ventilation duct. The light bulb can attract flies, insects, etc. that breed in the compost material. According to a preferred embodiment, the exhaust fan and the light bulb are connected in such a way that the speed of the exhaust fan increases when the light bulb is lit. The advantage of this design is that when the light bulb is lit, it will attract mosquitoes such as flies, and the speed of the exhaust fan will increase at this time, which can suck away flies and other mosquitoes. In addition, the ventilation duct also includes an ultraviolet radiation light source to kill germs in the air and eliminate the odor generated.

[0082] The liner bag 120 is provided with a discharge hole 121 for discharging the liquid separated from the compost. Preferably, an ultraviolet radiation light source may be provided in the discharge hole 121.

[0083] According to a preferred embodiment, the support base 112 and the liner bag 120 disposed in the container 100 form a composting unit, and when a composting unit is partially or completely filled, it is transported to a storage point in the form of a unit.

[0084] The liner bag 120 is closed but ventilated, and the compost material is decomposed in the liner bag 120 to prevent the spread of pathogens. The liner bag 120 is closed, so there will be no liquid leakage during the transportation and storage of the liner bag 120. Air can be introduced into the liner bag 120 to provide oxygen required for the effective decomposition of the compost material.

[0085] When the liner bag 120 is completely filled, the container 100 can be temporarily placed to wait for the contents in the liner bag to decompose and reduce the volume of the contents. The container 100 can continue to be used, which can reduce the number of transportations and save time and effort. Alternatively, the filled liner bag can be directly removed and transported to a storage point to be matured, and a new liner bag 120 can be replaced for use.

[0086] The container 100 has a simple structure, and the cost of manufacturing, transporting, storing, etc. is minimized. The supporting structure of the composting device can be reused, which can reduce the cost of composting.

[0087] Example 2

[0088] The support bottom 112 is provided with at least one inclined surface 150. Preferably, the support bottom 112 is provided with two inclined surfaces 150, and the inclined surfaces 150 are inclined in a manner of being away from or opposite to each other. Preferably, the screening assembly 122 is arranged in the liner bag 120 parallel to the near-ground end of each inclined surface 150. The inclined surface 150 can be arranged at the outer lower part of the liner bag 120, and can also be arranged at the inner lower part of the liner bag 120.

[0089] like Figure 4As shown, the support member is provided with a horizontal box door 112.1, and a support rod 112.5 and a roller 112.4 are installed on the box door 112.1. The inclined plane 150 is inserted into the support bottom 112 in an unfixed form, and the height of the support block 140 is adjusted according to the required angle of the inclined plane 150. For example, when the height of the support block 140 is h1, the inclined angle of the inclined plane 150 is α; when the height of the support block 140 is h2, the inclined angle of the inclined plane 150 is β, wherein when h1 is less than h2, α is correspondingly less than β.

[0090] like Figure 5 As shown, the inclined surfaces 150 are disposed in a spaced-apart manner, and the screening assembly 122 is disposed along each side of the container 100 .

[0091] The inclined surface 150 may be made of a naturally degradable material. The support base 112 may be provided with an inclined surface 150, and the inclined surface 150 may be provided with drainage grooves 151 distributed along the slope direction, such as Figure 6 After the bottom of the liner bag 120 contacts the inclined surface 150, a liquid channel is formed at the bottom of the liner bag 120 that is consistent with the drainage groove 151, and the liquid separated from the compost material is led to the discharge hole 121 of the liner bag 120 through the liquid channel. The separated liquid is spread in the liquid channel that is consistent with the drainage groove 151 and flows to the discharge hole 121, which can prevent all the liquid from flowing through a channel formed in the compost material on the inclined surface 150.

[0092] A basically horizontal plate can be used instead of the inclined surface 150, and a drainage groove 151 is arranged on the horizontal plate, and the depth of the drainage groove 151 increases from the first end to the second end of the horizontal plate. Therefore, a plurality of inclined surfaces 150 can be formed in the drainage groove 151, so that the liquid can be guided from the drainage groove 151 to the screening assembly 122 and flow out of the inner liner bag 120.

[0093] When the inclined surface 150 is disposed at the lower part of the inner liner bag 120 , the inclined surface 150 can be made of a cheap material because the inclined surface 150 is also replaced when the inner liner bag 120 is replaced.
