Description

Technical Field

[0001] This utility model relates to the field of plant residue treatment technology, and in particular to a plant residue treatment device. Background Technology

[0002] Tea is widely used in the food, beverage, and deep processing industries, resulting in a huge consumption volume and a significant amount of plant residue, which has become a considerable byproduct. Because the collected plant residue is typically high in moisture and sticky, it easily clumps together during storage and transportation. Existing processing equipment struggles to efficiently and effectively disperse and process it, leading to frequent internal blockages after the plant residue enters the equipment. Furthermore, the clumped plant residue's interior cannot fully contact the microorganisms, creating fermentation dead zones and causing localized spoilage; while the exterior of the plant residue, due to full exposure, undergoes excessive decomposition. This severely impacts the quality of the recycled plant residue. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 4This utility model provides a plant residue treatment device, including a pretreatment chamber 100, with an inlet 110 at the top and a first outlet (not shown in the figure). A preliminary crushing component is provided inside the pretreatment chamber 100 to perform preliminary crushing treatment on the plant residue input to the inlet 110. A biological purification chamber 200 is also included, with its inlet connected to the first outlet. The biological purification chamber 200 includes a loosening mechanism 210, a storage chamber 220 for storing functional microorganisms, and an outlet 230. The loosening mechanism 210 loosens the plant residue during purification, the functional microorganisms purify the plant residue, and the outlet 230 discharges the purified and loosened plant residue.

[0021] It should be noted that plant residues may include tea residues, flower residues, and grass residues; this embodiment does not specifically limit them.

[0022] Plant residues are first fed into the pretreatment chamber 100 through a universal inlet 110 at the top. This inlet 110 is designed to accommodate plant residues from different sources (such as clumps of residues accumulated in tea factories or wet residues filtered from tea shops), effectively preventing blockages and ensuring a continuous and smooth feeding process.

[0023] Upon entering the pretreatment chamber 100, the built-in preliminary crushing component is immediately activated. Through mechanical extrusion and grinding, it effectively breaks down the agglomerated structure of the residue, decomposing it into smaller particles. This pretreatment process not only significantly reduces the mass transfer resistance of subsequent processes, laying the physical foundation for efficient reactions with functional microorganisms, but also effectively prevents jamming problems that may be caused by large pieces of residue during transportation.

[0024] The initially crushed plant residue is transferred to the biological purification chamber 200 through the first outlet at the bottom of the pretreatment chamber 100. Inside the biological purification chamber 200, the loosening mechanism 210 performs secondary treatment on the initially crushed plant residue, breaking up any re-agglomerations caused by humidity and gravity in real time, ensuring that the plant residue remains in a uniform and loose physical state. This increases the surface area of ​​the plant residue and significantly enhances the contact area between the plant residue and the functional microbial community.

[0025] Once the plant residue reaches the ideal fine and loose state, the functional microbial community quickly attaches to its surface. Through the bio-metabolic action of the functional microbial community, it efficiently decomposes organic components such as cellulose, hemicellulose, and tea polyphenols in the residue. During this process, the bioheat generated by the microbial community's metabolism is simultaneously used to evaporate the moisture in the plant residue, achieving biodegradation and material drying in the same reaction environment.

[0026] Once the purification and drying processes are complete, the plant residue has been transformed into a stable, dry granular product. At this point, the discharge port 230 at the end of the biological purification chamber 200 automatically opens, discharging the final product for subsequent resource utilization.

[0027] The pretreatment chamber 100 is also equipped with a hoist 120, which includes a first track 121, a second track 123 and a placement tray. The first track 121 and the second track 123 are parallel and spaced apart on the same outer side wall of the pretreatment chamber 100 and extend along the height direction of the pretreatment chamber 100. The left side of the placement tray is slidably engaged with the first track 121 and the right side is slidably engaged with the second track 123. It is used to carry the plant residue to be treated and move up and down along the extension direction of the first track 121 and the second track 123 to transport the plant residue to the feed inlet 110.

[0028] It should be noted that the placement tray is positioned at a lower level on the outer side of the pretreatment chamber 100, allowing operators to easily pour or place the collected plant residue into it. At this time, the placement tray is located at the bottom of the first track 121 and the second track 123. After loading the plant residue, the lifting mechanism 120 is activated. With the combined action of the first track 121, the second track 123, and the placement tray, the placement tray will not sway back and forth or side to side during lifting, ensuring precise and stable movement. The placement tray rises smoothly along the first track 121 and the second track 123, which are parallel to the outer side of the pretreatment chamber 100, transporting the plant residue from the loading point at the lower level of the pretreatment chamber 100 to the inlet 110 at the higher level. When the placement tray rises to a position aligned with the inlet 110, it automatically flips over, thus pouring the plant residue into the inlet 110 of the pretreatment chamber 100.

[0029] The pretreatment chamber 100 is equipped with a preliminary crushing component, which is used to perform preliminary crushing pretreatment on the plant residue input to the feed inlet 110.

[0030] It should be noted that after the plant residue is initially crushed, it forms tea residue with regular shape and uniform size. This is to avoid large pieces of plant residue from clogging the pretreatment chamber 100, reduce the downtime for cleaning caused by material jamming in the pretreatment chamber, and ensure the continuous and stable operation of the entire processing equipment.

[0031] Reference Figure 2 and Figure 3The loosening mechanism 210 includes a first driving unit 211 and a stirring unit 212. The first driving unit 211 drives the stirring unit 212 to rotate to break up and loosen the plant residue in the biological purification chamber 200. The stirring unit 212 includes a rotating screw 2121 and a plurality of stirring arms 2122. The rotating screw 2121 extends horizontally along the biological purification chamber 200, and one end of the rotating screw 2121 is connected to the first driving unit 211. The plurality of stirring arms 2122 are arranged sequentially at intervals along the axial direction of the rotating screw 2121. Each stirring arm 2122 extends radially outward along the rotating screw 2121, and the rotation angles of adjacent stirring arms 2122 are staggered.

[0032] It should be noted that the length of the rotating screw 2121 is consistent with the internal space length of the purification chamber, and the rotating screw 2121 is provided with multiple radially extending agitator arms 2122 at intervals along the axial direction. When the screw rotates, these agitator arms 2122 can effectively cover the entire working area inside the purification chamber, achieving comprehensive agitation of the plant residue.

[0033] After initial crushing in the pretreatment chamber 100, the plant residue is conveyed to the biological purification chamber 200. At this time, the first drive unit 211 is activated, driving the rotating screw 2121 to rotate. Multiple agitator arms 2122 mounted on the screw rotate accordingly, directly cutting into and agitating the plant residue. Furthermore, because adjacent agitator arms 2122 are arranged at staggered angles, the agitator arms 2122 can stir the plant residue from different directions during rotation.

[0034] The stirring arm 2122 in this embodiment can impact and stir the plant residue from multiple angles and directions, effectively breaking up clumps and preventing the plant residue from being pushed together in one direction, thus eliminating stirring dead zones. This not only ensures uniform mixing of temperature, humidity, and microbial environment of the plant residue in each area of ​​the biological purification chamber 200, but also significantly improves the uniformity of the plant residue purification and drying process. In addition, the staggered stirring method effectively prevents plant residue from tangling and accumulating, avoiding blockages.

[0035] An environmental acquisition unit is installed inside the biological purification chamber 200. The environmental acquisition unit includes a temperature sensor for detecting the temperature inside the biological purification chamber 200 and a humidity sensor for detecting the humidity inside the biological purification chamber 200. The temperature sensor and the humidity sensor are evenly distributed inside the biological purification chamber 200.

[0036] It should be noted that the environmental acquisition unit includes temperature and humidity sensors evenly distributed within the chamber. These sensors are used to monitor the temperature and humidity within the bio-purification chamber 200 in real time, thereby comprehensively acquiring real-time environmental data during the purification process of plant residues.

[0037] The biological purification chamber 200 is also equipped with an air conditioning device 240, which is used to transfer air from outside the biological purification chamber 200 to inside the biological purification chamber 200.

[0038] It should be noted that the biological purification of plant residues relies on the metabolic activities of aerobic microorganisms. The air conditioning device 240 continuously supplies fresh air from outside the chamber, ensuring sufficient oxygen to meet the needs of aerobic bacteria in decomposing organic pollutants (such as residual organic matter and odor substances) in the plant residues. This significantly improves the degradation rate and shortens the overall purification cycle. Compared to the large fluctuations in oxygen concentration caused by natural ventilation, the air conditioning device 240 can precisely control the air input, maintaining the oxygen concentration within the biological purification chamber 200 within the optimal range for microbial metabolism. This avoids localized hypoxia leading to the generation of harmful gases such as hydrogen sulfide during anaerobic purification, ensuring a stable biological purification process for the plant residues and consistent purification effects across all areas within the biological purification chamber 200. Specifically, the air conditioning device 240 includes, but is not limited to, intake and exhaust fans, gas flow control valves, and corresponding ventilation ducts to maintain a suitable gaseous environment within the reaction purification chamber.

[0039] Reference Figure 3 and Figure 4 The air conditioning device 240 includes an air duct 241 installed on the wall of the biological purification chamber 200, a fan 242 installed in the air duct 241 for transmitting air from outside the biological purification chamber 200 to inside the biological purification chamber 200, and an air filter membrane 243 installed on the air duct 241.

[0040] It should be noted that the air duct 241 is integrated into the wall of the biological purification chamber 200. Its orientation (such as multiple sets of side-supply air ducts 241) can be designed according to the distribution characteristics of the plant residue pile within the biological purification chamber 200, achieving directional and uniform air delivery to all areas of the chamber. This avoids dead zones in natural airflow, ensuring a balanced oxygen supply inside the biological purification chamber 200. The airflow inside the biological purification chamber 200 is controlled by adjusting the speed of the fan 242. Furthermore, the air input is dynamically adjusted according to the oxygen demand at different stages of plant residue purification (e.g., high oxygen demand during initial microbial proliferation and reduced oxygen demand during later stages of degradation), preventing oxygen excess or deficiency and maximizing microbial metabolic efficiency. Furthermore, the air filter membrane 243 can effectively intercept impurities such as dust, particulate matter, bacteria, and insect eggs in the air outside the chamber, preventing these pollutants from entering the biological purification chamber 200 and attaching to the plant residue pile. This prevents bacteria from competing with functional microorganisms for nutrients or insect eggs from breeding in the pile, ensuring that the plant residue treatment process is not affected by external sources and guaranteeing the quality of the plant residue.

[0041] The biological purification chamber 200 is also equipped with a display module 250, which is used to display humidity and temperature data inside the biological purification chamber 200.

[0042] It should be noted that the display module 250 displays at least one of the following information: real-time environmental parameters: including but not limited to real-time temperature, real-time humidity, oxygen concentration and key air quality parameters in the biological purification chamber 200; equipment operating status: indicating the current working mode (such as running, standby, fault) and output intensity of the air conditioning device 240, temperature control device and humidity control device in the form of icons or text; process parameter settings: displaying the target temperature, target humidity and other parameter thresholds set for the current purification process; historical data curves: able to trace and display the change curves of key environmental parameters (such as temperature) within a specified time period in the form of trend graphs.

[0043] Both the pretreatment chamber 100 and the biological purification chamber 200 are equipped with casters at their bottom. It should be noted that the casters allow the pretreatment chamber 100 and the biological purification chamber 200 to function as independent modular units, enabling them to be moved and repositioned quickly and flexibly according to the needs of the actual production site, process flow optimization, or capacity expansion.

[0044] The biological purification chamber is also equipped with a dryness detection module and an alert unit. The dryness detection module is used to detect the dryness of the plant residue, and the alert unit is used to issue an alarm.

[0045] It should be noted that the dryness of plant residue directly affects the activity of functional microorganisms within the bio-purification chamber. Excessive humidity can lead to the growth of harmful bacteria in an anaerobic environment, while insufficient humidity inhibits microbial metabolism and hinders the degradation of organic matter in the plant residue. This embodiment uses a dryness detection module to track the dryness data of the plant residue in real time. Once the dryness exceeds the suitable humidity range for the functional microorganisms, an alarm is immediately triggered. Staff can then adjust ventilation, drying, and other relevant parameters to ensure that the functional microorganisms are always in an optimal metabolic state, maintaining the high efficiency of the plant residue treatment process.
