Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste treatment, in particular to a solid waste treatment equipment for urban environmental protection. BACKGROUND

[0002] In the field of urban garbage treatment, as an important component, the core source of market garbage is the plant-derived vegetable and fruit waste generated in vegetable markets. Such waste is mostly rotten or discarded vegetable materials. The conventional treatment path is to recycle them through compaction and then use them for composting or incineration. The above-mentioned treatment methods can effectively achieve environmental protection, and at the same time, can realize waste utilization and achieve the policy of energy saving and emission reduction.

[0003] However, in the process of compaction treatment of such plant-derived vegetable and fruit waste in the prior art, due to the characteristics of the material itself, the "arch bridge phenomenon" is prone to occur: the particle morphology of such waste is irregular, and contains a large amount of fiber components such as vegetable leaf veins. When subjected to pressure in the closed space of the compaction chamber, the material particles will form a stable support structure similar to an arch bridge due to mutual hooking and occlusion, and the fiber components will also cross and entangle to form a fiber arch. The above structure can withstand the subsequent compaction pressure, resulting in local arching and uneven compaction of the material inside the compaction chamber, which cannot achieve uniform compaction. In the prior art, the treatment scheme for compaction of plant-derived vegetable and fruit waste lacks targeted design, and it is difficult to effectively solve the above-mentioned problems, which will further negatively affect the subsequent composting and incineration treatment: in the composting link, if the compacted material appears unevenly as over-dense mud-like clumps, it will be difficult for oxygen to enter the inside of the clumps, and microorganisms will be inactivated or even die due to lack of oxygen, hindering the fermentation process and preventing the formation of qualified organic fertilizer. If the porosity is out of control due to uneven compaction, it will also disrupt the reasonable environment required for composting, and additional costs will be incurred to adjust the material ratio. In the incineration link, uneven compaction will cause large differences in the form of the material, and some fine materials will be easily scattered during transportation, not only causing material loss, but also causing incomplete combustion during incineration, producing pollutants such as black smoke, and increasing the difficulty and cost of fly ash treatment. Some large pieces of material that are not fully compacted will also affect the incineration efficiency due to uneven burning area, and will not achieve the desired effect of reduction.

[0004] In summary, the current compaction treatment of urban market garbage, i.e. plant-derived vegetable and fruit waste, urgently needs a technical solution that can effectively solve the arch bridge phenomenon, achieve uniform distribution and compaction, and adapt to the subsequent composting and incineration treatment requirements, in order to make up for the shortcomings of the existing treatment methods and improve the overall treatment efficiency and environmental protection.

[0005] Therefore, the present application proposes a solid waste treatment equipment for urban environmental protection to solve the above problems. SUMMARY

The waste treatment group is used for providing structural support for the treatment of plant source waste. The anti-splashing fiberization treatment conveying group is used for ensuring stable conveying of the plant source waste during the treatment and avoiding splashing and blocking. The uniform distribution type compression group is used for compression of the plant source waste after fiberization treatment, avoiding the compression "arch bridge phenomenon" caused by the existing plant source waste fibers. The adaptive slag removal and filtration group is used for stable transfer of moisture during compression of the plant source waste. The waste treatment group comprises a treatment box body, a discharge port is formed on the treatment box body, a vertical chute is formed on the treatment box body, and a sealing plate is vertically inserted into the chute.

[0009] Preferably, the top of the pressing plate is bent, and the stop position of the bent part does not exceed the inner end groove wall of the limiting groove. The cylindrical teeth on the two toothed rollers of the roller shaft A and the roller shaft B are arranged in a staggered manner, that is, the teeth of one toothed roller correspond to the tooth gaps of the other toothed roller.

[0010] As preferred, the uniform distribution type compression group comprises a telescopic hydraulic cylinder fixed in the processing box, a groove is formed in the inner wall of the processing box, a pushing plate is slidably connected in the groove, the output end of the telescopic hydraulic cylinder is fixedly connected with the side wall of the pushing plate, and a plurality of conical spike members are fixedly connected on the pushing plate at equal intervals. A bottom plate is obliquely and slidably connected in the processing box, the two side walls of the bottom plate are obliquely and tightly connected with the inner wall of the processing box, and a plurality of water discharge holes are formed in the bottom plate at equal intervals.

[0011] As preferred, the adaptive slag removal and filtration group comprises a sleeve fixed in the bottom plate, a torsional spring is fixedly connected in the inner cavity of the sleeve, and a shaft B is fixedly connected to the outer end of the torsional spring. A baffle plate is arranged in the water discharge hole, a secondary plate is connected to the bottom plate in a mortise and tenon joint mode, a plurality of vertical grooves are formed in the bottom of the secondary plate at equal intervals, and a plurality of filter cartridges are threadedly connected in the vertical grooves. An electric regulating valve is fixedly connected to the telescopic hydraulic cylinder, a water pipe is fixedly connected to the electric regulating valve, and one end of the water pipe, away from the electric regulating valve, is fixedly inserted into the bottom plate. A water passing groove is formed in the upper surface of the secondary plate, and the water pipe is in communication with the water passing groove. The shaft B is fixedly connected with the baffle plate, and the baffle plate rotates in the water discharge hole about the shaft B, so as to adjust the gap through which water flows.

[0012] As preferred, the two clamping plates are a group, and the gap between the two clamping plates is a plant source waste passing path.

[0013] As preferred, the combination of the bottom plate and the secondary plate divides the inner cavity of the processing box into two regions in the longitudinal direction, specifically, a working area and a water collecting area. Above the bottom plate, the pushing plate divides the inner cavity of the processing box into two regions in the transverse direction, specifically, a cavity area and a compression processing area, and the two regions jointly form the working area.

[0014] As preferred, the water passing groove is composed of a main water passing groove and a branch water passing groove.

[0015] Compared with the prior art, the present application provides a solid waste treatment equipment for urban environmental protection, which has the following advantages: 1. The design of the anti-splashing fiberization treatment conveying group, especially the addition of the pressing plate, can bring the following benefits to the transfer and treatment of plant source waste. Solve the problem of material sliding idling, ensure the continuity of transfer: plant waste (such as vegetable leaves, stems) is soft and often attached with water on the surface, only relying on the rotation of the roller shaft is easy to appear "material sliding on the roller shaft, not with the roller shaft downward transfer" idling situation. The pressing plate can exert a continuous and uniform downward pressure on the waste on the roller shaft under the action of the spring force, tightly pressing the material on the surface of the roller shaft, greatly increasing the friction between the material and the roller shaft; when the roller shaft rotates, the friction can effectively move the material with the roller shaft, avoid sliding, ensure the stable downward transfer of the material, eliminate the invalid operation of "roller shaft rotation, material not rotation", and protect the continuous transfer process. Prevent material splashing loss, optimize operation environment and material utilization rate: when the roller shaft rotates to transfer the material, if the material is not constrained, it is easy to appear "vegetable leaves, broken stems flying" splashing phenomenon due to centrifugal force or tooth cylinder, which not only causes material loss, but also pollutes the environment around the equipment, increases the subsequent cleaning cost. The conveying channel formed by the pressing plate and the roller shaft, and the two clamping plate pieces forms a semi-closed transfer space, which can effectively form a physical barrier to the material from above, effectively intercepting the splashing material; even if a small amount of material is displaced due to extrusion, it will be blocked by the pressing plate and pressed back to the roller shaft surface for continuous transfer, which not only reduces material loss and improves utilization rate, but also avoids site pollution and reduces environmental cleaning workload.

[0016] 2、The present application can bring the following benefits through the pressing / extrusion of the roller shaft A and the roller shaft B during the transfer process of plant waste, and the further processing of the uniformly distributed compression group: Directly hit the compaction pain point, greatly improve the compaction quality and efficiency of plant waste: the roller shaft first breaks the long fibers of the vegetables by extrusion, preliminarily breaking the possibility of fiber cross-winding; the subsequent conical spike further pierces the remaining fiber bundle, avoiding the formation of "fiber arch" by re-hooking the fibers; at the same time, the conical spike can pierce the plastic bag / vegetable leaves wrapped around the water, eliminating the "flexible support point"; the two cooperate to cut off the arch bridge phenomenon from the two core causes of "fiber winding" and "water wrapping", so that the material is evenly stressed in the compaction chamber, and the problem of local arching and uneven compaction no longer occurs, the consistency of the material density after compaction is significantly improved, laying a stable foundation for subsequent processing; Accelerate solid-liquid separation, reduce moisture content, and reduce moisture return after compaction: after the conical spike pierces the "water wrapping layer" of the plastic bag / vegetable leaves, the free water inside the material can be directly transferred, avoiding the water being wrapped inside the material and unable to be discharged; at the same time, after the roller shaft extrudes the fibers, the material structure is more loose and the water permeation path is more unobstructed; under the double action, the water discharge efficiency during the compaction process is greatly improved, the moisture content of the material can be effectively reduced, avoiding "secondary moisture return" after compaction due to water retention, reducing the dripping pollution during the material transportation process and the additional dehydration cost of subsequent processing.

[0017] 3, The design of the present application is to place the bottom plate in the processing box body by inclined sliding, which can bring the following benefits: Optimize the initial distribution of materials, and provide a uniform basis for subsequent compaction: plant-derived waste (such as vegetable leaves and roots) is soft in texture. If the bottom plate is placed horizontally, the material will accumulate in local areas and form a "mountain-like" stack when it falls from above, resulting in "local over-thickness and local vacancies" in the processing box body. The inclined bottom plate uses the weight of the material to guide it to slide naturally down the slope. In the process, the material will automatically disperse along the slope, avoiding local accumulation and achieving natural dispersion. At the same time, the sliding process can slightly break up the clumped material, allowing the material to form a "thin and uniform" initial distribution state in the processing box body without the need for additional manual or mechanical leveling, providing a prerequisite for "uniform feeding" for the subsequent compaction process, and reducing the uneven compaction caused by material thickness differences from the source; Strengthen the directional flow of water, improve the efficiency of solid-liquid separation and equipment protection: plant-derived waste has a high water content, which will continue to be squeezed out during the roller shaft extrusion and subsequent compaction process. The horizontally placed bottom plate is prone to cause water to stagnate on the bottom plate, and some of the water will be reabsorbed by the material (i.e., "secondary moisture return"), affecting the dehydration effect. The inclined bottom plate provides a clear flow direction for the water, allowing the squeezed-out water to flow quickly along the slope, thereby accelerating the extrusion of water, reducing the water content of the material, reducing the residence time of water on the bottom plate, and avoiding being reabsorbed by the material, significantly improving the overall dehydration efficiency; Avoid water stagnation and corrosion, and prolong the service life of the equipment: the stagnant water contains organic acids produced by vegetable rot, which can cause the bottom plate to rust and corrode if it is in contact with the flat bottom plate for a long time. The inclined design allows water to quickly drain away from the surface of the bottom plate, reducing the contact time between organic acids and the bottom plate and reducing the risk of equipment rusting. This can effectively reduce the problem of component aging and rusting, indirectly prolonging the overall service life of the equipment and reducing maintenance costs.

[0018] 4, The present application can bring the following benefits through the cooperation of "water channel + telescopic hydraulic cylinder": Precise control of compression degree, adapt to differentiated needs of composting / burning, and improve the quality of material processing: By setting the threshold value of the electric regulating valve according to the demand, it can effectively avoid the situation of excessive / insufficient compression; Different subsequent processing (composting / burning) requires different compression degrees of plant-derived waste. Composting requires a certain porosity to avoid excessive compression leading to oxygen deficiency, while burning requires higher density to reduce transportation volume and improve heat value. The design of the present application can preset the maximum compression pressure of the pushing plate through the electric regulating valve. When the pushing plate compresses the material to the preset pressure, the pressure in the telescopic hydraulic cylinder reaches the pressure relief threshold, and the electric regulating valve automatically releases the high-pressure water, stopping the pushing plate from moving due to the loss of pressure support, achieving "compression on demand" and accurately matching the differentiated needs of composting and burning, avoiding the decline in subsequent processing effect due to improper compression degree; Synchronous use of pressure relief high pressure water to achieve "compression and flushing", without additional power: the high pressure water discharged by the electric regulating valve (originally "redundant pressure carrier" to control compression stop) is directed to the filter cartridge through the water channel, and the high pressure water flow can impact the filter hole of the filter cartridge to flush away the vegetable leaf debris and fiber scraps stuck in the hole; the whole flushing process is carried out in the same process as the self-stop action of compression, without the need for additional flushing power components such as water pumps and motors, achieving "energy reuse", reducing water waste, avoiding poor drainage caused by filter hole blockage, and ensuring solid-liquid separation efficiency.

[0019] 5、The present application adopts mortise and tenon joint design of bottom plate and vice plate, which can bring the following benefits from "maintenance convenience": Non-destructive disassembly, quick contact maintenance parts: mortise and tenon joint does not need welding, bolt and other fixed connecting parts, when maintaining, only need to separate the bottom plate and the vice plate along the mortise and tenon joint surface, the baffle plate and the filter cartridge installed on the bottom plate / vice plate can be directly exposed; avoiding the need to disassemble or cut the traditional integrated plate body to access the internal components, which not only consumes time, but also damages the structure; the mortise and tenon design realizes "on-demand disassembly", and after maintenance, the seal can be restored by reassembling, without the need for additional repair or replacement of parts, significantly reducing maintenance time and part loss cost.

[0020] 6、The present application adopts "extrusion type processing of plant source waste" instead of "crushing type", the core is to avoid the pain points brought by crushing in the subsequent composting, incineration and overall processing process through the processing logic of "only breaking fibers without damaging the overall particle size of the material", which can bring the following benefits: Maintain reasonable porosity required for composting to avoid anaerobic death of microorganisms: extrusion only breaks vegetable fibers (such as leaf veins and stem fiber bundles), keeping the material in a "loose small block" form (instead of "fine material / mud-like mass" after crushing), and naturally forming pores between the blocks; this porosity exactly meets the needs of aerobic respiration of composting microorganisms, and oxygen can smoothly penetrate the material layer, avoiding local oxygen deficiency caused by dense clumping of crushed fine materials, eliminating the problem of reduced microbial activity or death, ensuring stable fermentation process, without the need for additional mixing of dry materials such as straw and sawdust to adjust the porosity, reducing composting auxiliary material cost; Reduce the mixing of fine slag and impurities to improve the purity of organic fertilizer: crushing will grind the material (including mixed plastic bag fragments and soil) into fine materials, which are difficult to separate, and eventually mixed into the fertilizer, resulting in a decrease in purity; extrusion does not damage the overall form of the material, and the mixed plastic bags and hard stems remain in large pieces, which can be easily separated through subsequent simple sorting, and there are very few small impurities in the fertilizer product after the extrusion process, the nutrient distribution is more uniform, meets the agricultural / greening fertilizer standard, and improves the resource utilization value; Reduce the risk of material moisture absorption and moisture return, and stabilize the compost humidity environment: the specific surface area of the crushed fine material is large, which is easy to adsorb the moisture in the air or the humidity generated during fermentation, resulting in "over-humidification" of the material, causing anaerobic odor; the specific surface area of the "loose small pieces" after extrusion is small, the moisture absorption capacity is weak, and part of the free water is squeezed out during the extrusion process, so the material humidity is closer to the ideal value of compost, and the humidity does not need to be adjusted frequently, avoiding the fermentation stagnation caused by humidity fluctuation, and shortening the composting period; Avoid fine material loss, and ensure material utilization and combustion completeness: fine material (such as crushed vegetable leaves and fiber ends) produced by crushing is easy to fly in the conveying process due to air flow or vibration, not only causing material loss, but also forming fly ash with the incineration flue gas, increasing the load of dust removal equipment; the "small piece material" after extrusion is stable in shape, has no flying problem during conveying, can enter the incinerator completely, and the size of the block is uniform, so that the heating area is consistent during combustion, and the situation of "local overheating and burning of fine material, and incomplete combustion of large block" does not occur, the combustion efficiency is improved, and the emission of black smoke and unburned material is effectively reduced; Extrude free water in advance to improve the stability of material calorific value: plant waste has a high water content, and crushing can mix water and fine material thoroughly, forming "wet mud", which is difficult to remove in advance, resulting in the need to consume a large amount of heat to evaporate water during incineration, and the calorific value fluctuates greatly; a large part of the free water can be directly squeezed out during the extrusion process, and can be discharged through the inclined bottom plate and the slag removal filter group, so that the water content of the material is low, and there is no need to frequently add combustion-supporting agents such as natural gas and diesel oil during incineration treatment, and the energy consumption cost per ton of material incineration is effectively reduced; Reduce the generation of harmful gases and the cost of tail gas treatment: after the fine material is mixed with the plastic bag fragments, dioxin is easily generated due to local temperature unevenness (overhigh temperature in the fine material area and low temperature in the large block area) during incineration (dioxin is easily synthesized in the low temperature area); in the extrusion process, the plastic bag remains in a large block shape and can be separated in advance, and the material is fully combusted (without local low temperature), so the amount of dioxin generated is reduced; at the same time, the amount of fly ash is reduced without fine material flying, so that the dust removal equipment does not need to be upgraded, the replacement frequency of consumables (such as filter bags) for tail gas treatment is reduced, and the environmental protection treatment cost is significantly reduced.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0024] The application will be further described in detail below according to the drawings and embodiments.

[0025] EMBODIMENT Please refer to Figures 1 to 5 shown: To solve the problems mentioned in the technical solutions, the application embodiments provide a solid waste treatment equipment for urban environmental protection, which comprises a waste treatment group, and further comprises an anti-splashing fiberization treatment conveying group, a uniformly distributed compression group and an adaptive slag removal filter group. The anti-splashing fiberization treatment conveying group is arranged on the top of the waste treatment group, and the uniformly distributed compression group and the adaptive slag removal filter group are arranged inside the waste treatment group. The waste treatment group is used for providing structural support for the treatment of plant source waste; The anti-splashing fiberization treatment conveying group is used for ensuring stable conveying of the plant source waste during the treatment and avoiding splashing and blockage; The waste treatment group comprises a treatment box 101, a discharge port 102 is formed on the treatment box 101, a vertical chute is formed on the treatment box 101, a sealing plate 103 is vertically inserted into the chute, and a handle for easy operation is fixedly connected to the sealing plate 103; a sliding groove 106 is symmetrically formed on the upper part of the treatment box 101, a clamping plate 104 is slidably connected in the sliding groove 106, and a hole groove 105 is equidistantly and vertically formed on the bottom end of the clamping plate 104; an auxiliary hole matching the hole groove 105 is formed on the upper part of the treatment box 101, and a plug-in column 107 is inserted into the hole groove 105 and the auxiliary hole, so as to limit the clamping plate 104; The anti-splashing fiberization treatment conveying group comprises a shaft A201 fixedly connected to the inner wall of the clamping plate 104, a pressing plate 202 rotatably connected to the shaft A201, and a limiting groove 203 formed on the upper end of the clamping plate 104; a spring 204 is fixedly connected in the limiting groove 203, and the outer end of the spring 204 is fixedly connected to the top of the pressing plate 202; a roller shaft A205 is rotatably connected in the clamping plate 104, and another clamping plate 104 is provided with a roller shaft B206.

[0026] Among them: A through port is formed on the top of the treatment box 101 for position transfer of the plant source waste; a groove is formed on the inner wall for sliding of the bottom plate 304 for movement thereof. A transfer pipe is formed on the bottom of the treatment box 101 for transfer of compressed waste moisture. The discharge port 102 provides a channel for transfer of the compressed waste block. The two clamping plates 104 form a group; the gap between the two clamping plates can be adjusted to adapt to plant source waste of different sizes. The plug-in column 107 matches the hole groove 105. If the plant source waste is large, it can be properly treated before compression. The top of the pressing plate 202 is bent, which can be used to hinder the upward movement of the plant source waste when pressing the plant source waste, so as to reduce splashing and assist the rapid transfer of the plant source waste. The top of the pressing plate 202 is bent, and the bending part moves to a position not exceeding the inner end groove wall of the limiting groove 203. The cylindrical teeth on the two tooth rollers of the roller shaft A205 and the roller shaft B206 are arranged in a staggered manner; that is, the teeth of one tooth roller correspond to the tooth gap of the other tooth roller; the roller shaft A205 and the roller shaft B206 are driven by a motor.

[0027] The two clamping plates 104 form a group, and since the anti-splashing fiberization treatment conveying groups in them are consistent, only one clamping plate 104 is labeled and described in this design.

[0028] Further embodiments: please refer to Figure 1 , Figure 3 , Figure 4 , Figures 6 to 10 , The uniform distribution type compression group is used for compression of plant source waste after fiberization treatment, and avoids the compression "arch bridge phenomenon" caused by the existing plant source waste fibers. The adaptive slag removal and filtration group is used for stable water transfer during compression of plant source waste. The uniform distribution type compression group includes a telescopic hydraulic cylinder 301 fixed in the treatment box 101, a channel is formed in the inner wall of the treatment box 101, a pushing plate 302 is slidingly connected in the channel, the output end of the telescopic hydraulic cylinder 301 is fixedly connected with the side wall of the pushing plate 302, and the pushing plate 302 is fixedly connected with a conical spike 303 at equal intervals; a bottom plate 304 is slidingly connected in the treatment box 101, the two side walls of the bottom plate 304 and the pushing plate 302 are both oblique surfaces that fit the inner wall of the treatment box 101, a drain hole 305 is formed in the bottom plate 304 at equal intervals, the adaptive slag removal and filtration group includes a sleeve 401 fixed in the bottom plate 304, a torsional spring 402 is fixedly connected in the inner cavity of the sleeve 401, and a shaft B 403 is fixedly connected with the outer end of the torsional spring 402; a baffle plate 404 is arranged in the drain hole 305, a secondary plate 405 is connected with the bottom plate 304 through mortise and tenon joint, a vertical groove is formed in the bottom of the secondary plate 405 at equal intervals, and a filter cylinder 407 is threadedly connected in the vertical groove; an electric regulating valve 4061 is fixedly connected with the telescopic hydraulic cylinder 301, a water pipe 4062 is fixedly connected with the electric regulating valve 4061, one end of the water pipe 4062 away from the electric regulating valve 4061 is fixedly inserted into the bottom plate 304, a water passage 4063 is formed in the upper surface of the secondary plate 405, and the water pipe 4062 is in communication with the water passage 4063; the shaft B 403 is fixedly connected with the baffle plate 404, and the baffle plate 404 rotates in the drain hole 305 about the shaft B 403 as an axis.

[0029] Among them: The telescopic hydraulic cylinder 301 is connected with an external water pump; the high-pressure water pump inputs water into the telescopic hydraulic cylinder 301 to drive the pushing plate 302 to compress the plant source waste.

[0030] The multi-stage design of the telescopic hydraulic cylinder 301 can reduce the length when shrinking, reduce the occupied space, and the reset spring is arranged in the inside.

[0031] The combination of the bottom plate 304 and the secondary plate 405 divides the inner cavity of the treatment box 101 into two regions in the longitudinal direction, specifically: a working area and a water collecting area.

[0032] Above the bottom plate 304, the pushing plate 302 divides the inner cavity of the treatment box 101 into two regions in the transverse direction, specifically: a cavity area and a compression treatment area; the two regions jointly constitute a working area.

[0033] The conical piercing member 303 can further pierce the fibers of the plant-derived waste, further reducing the phenomenon of fiber cross-winding in compaction, forming a "fiber arch"; at the same time, it can pierce the plastic bag wrapped around the water, avoiding the plastic bag from wrapping water into a ball in compaction, forming a "flexible support point" that hinders the surrounding water from being squeezed out and the material from being densified.

[0034] The drain hole 305 can be opened with different sizes according to specific use.

[0035] The bottom plate 304 is arranged obliquely in the treatment box 101, which can make the plant-derived waste roll down under the action of gravity when it falls, avoiding the stacking situation when the bottom plate 304 is arranged horizontally.

[0036] The torsional spring 402 is used for resetting the shaft B403. When the water flow is small, the baffle plate 404 is closed under the action of the torsional spring 402, and the water slowly flows into the water collection area through the drain hole 305, avoiding the fine slag from being carried into the wastewater transfer pipe with the water flow, causing blockage; when the water volume is too large, such as a large amount of water at the initial stage of compaction, the water pressure pushes the baffle plate 404 to open, and the water is quickly drained to prevent water accumulation in the compression treatment area.

[0037] The sub-plate 405 also has a drain hole 305, and for the convenience of work description, only one is described and labeled.

[0038] The telescopic hydraulic cylinder 301 is provided with a pressure sensor, and the electric regulating valve 4061 detects the water pressure in the telescopic hydraulic cylinder 301 in real time through the pressure sensor. When the water pressure in the telescopic hydraulic cylinder 301 reaches a certain value, the pressure sensor converts the water pressure signal into a standard electric signal and transmits it to the device general controller, so that the electric regulating valve 4061 is opened. At this time, the high-pressure water body will quickly enter the water channel 4063 from the water pipe 4062 and be introduced into the filter cartridge 407, washing the filter cartridge 407 to avoid blockage of the filter hole by accumulated fine slag; and the double use of water body can reduce the consumption of water resources.

[0039] The water channel 4063 is composed of a main water channel and a branch water channel; and the tangent direction of the branch water channel can be arranged along the tangent direction of the drain hole 305, so that the water body forms a cyclone in the filter cartridge 407 when the high-pressure water is drained, improving the washing effect.

[0040] The bottom plate 304 and the sub-plate 405 are connected in a splicing manner, which can facilitate the layered maintenance of the baffle plate 404 and the filter cartridge 407.

[0041] The working principle of all the contents in the above embodiments is as follows: The working process of the device revolves around the "material preparation → fiberization → uniform compression → solid-liquid separation → unloading and maintenance" five core stages, and each component works together to solve the "arch phenomenon" of plant waste compaction, while achieving efficient water treatment. The specific process is as follows: Stage one, preparation before starting the device Sealing plate 103 fixation: The sealing plate 103 is inserted and fixed on the processing box 101 through the sliding slot on the processing box 101, so as to avoid material leakage from the discharge port 102 during work.

[0042] Adjustment of clamping plate 104: According to the size of the plant waste (such as vegetable leaves and stems) to be treated, adjust the distance between the two clamping plates 104 along the sliding groove 106 on the upper part of the processing box 101. After adjustment, insert the insertion column 107 into the hole slot 105 of the clamping plate 104 and the auxiliary hole of the processing box 101 to realize the limiting fixation of the clamping plate 104, and ensure the stability of subsequent conveying.

[0043] External connection: Connect the telescopic hydraulic cylinder 301 of the uniformly distributed compression group with the external high-pressure water pump. According to the subsequent processing requirements (composting / burning), adjust the preset compression pressure of the electric regulating valve 4061.

[0044] Stage two, material feeding and fiberization conveying stage Material feeding: Put the plant waste into the processing box 101 from the top opening. The waste first contacts the pressing plate 202 of the anti-splashing fiberization conveying group.

[0045] Anti-splashing and anti-idling: The pressing plate 202 is under the elastic force of the spring 204 in the limiting groove 203, which applies continuous downward pressure to the waste to prevent it from sliding and idling on the roller shaft. At the same time, the bending structure of the pressing plate 202 forms a semi-closed space to prevent material from splashing due to the rotation of the roller shaft.

[0046] Preliminary fiber breakage: The roller shaft A 205 and the roller shaft B 206 in the clamping plate 104 are driven by the motor to rotate. The cylindrical teeth of the two rollers are arranged in an "interleaved manner", which can press and crush the waste during conveying, break the long fibers of the vegetables, and preliminarily break the possibility of fiber cross-winding. The material then falls into the working area of the processing box 101 below.

[0047] Stage three, uniform compression processing stage Natural distribution of materials: The bottom plate 304 in the processing box 101 is inclined, and the falling material slides along the inclined surface under the action of gravity, avoiding local accumulation and forming a uniform initial distribution state.

[0048] High-pressure driving compression: The external high-pressure water pump inputs high-pressure water into the telescopic hydraulic cylinder 301, pushing the pushing plate 302 to move along the inner wall groove of the treatment box 101 to the compression treatment area, and compressing the material.

[0049] Solve the "arch bridge phenomenon": the synchronous action of the conical spike 303 on the pushing plate 302, on the one hand, pierces the residual fiber bundle, preventing the fiber from reconnecting to form a "fiber arch"; on the other hand, it pierces the plastic bag or leaf wrapping the moisture, eliminating the "flexible support point", ensuring that the material is evenly stressed in the compaction chamber, without local arching, loose compaction, and uneven problems.

[0050] Compression self-stop control: when the pushing plate 302 compresses the material to the preset pressure of the electric regulating valve 4061, the water pressure in the telescopic hydraulic cylinder 301 reaches the pressure relief threshold, the electric regulating valve 4061 automatically opens, and high-pressure water is introduced into the water channel 4063 through the water pipe 4062, the pushing plate 302 stops moving due to the loss of water pushing force support, realizing "on-demand compression" (retaining porosity for composting, increasing density for incineration).

[0051] Stage four, solid-liquid separation and moisture treatment stage Moisture preliminary discharge: the free water squeezed out of the material during compression flows downward through the drain hole 305 on the bottom plate 304 and enters the processing range of the adaptive slag removal filter group.

[0052] Baffle sheet 404 self-adaptive adjustment: the baffle sheet 404 in the drain hole 305 is controlled by the shaft rod B403 and the torsional spring 402: when the water volume is small, the baffle sheet 404 is closed under the action of the torsional spring 402, and the moisture slowly flows into the water collection area through the water channel 4063, avoiding the blockage of the pipeline by fine slag with water flow; when the water volume is too large at the beginning of compaction, the water pressure pushes the baffle sheet 404 to open, realizing rapid drainage and preventing water accumulation in the compression area.

[0053] Filtering and automatic flushing: the moisture is guided to the filter cylinder 407 at the bottom of the vice plate 405 through the water channel 4063, and the high-pressure water discharged from the electric regulating valve 4061 will flush the fine slag, fiber debris, etc. trapped in the filter cylinder 407, thereby flushing away the impurities blocking the filter holes, realizing "compression and flushing", without the need for additional power; and improving the utilization rate of water resources.

[0054] Stage five, unloading and equipment maintenance stage Compression material unloading: after compression is completed, the unloading port 102 is exposed by opening the sealing plate 103, and the compacted material block is removed from the unloading port 102 for subsequent composting or incineration.

[0055] Component maintenance: if the filter cartridge 407 needs to be cleaned or the baffle plate 404 needs to be repaired, the mortise and tenon connection between the bottom plate 304 and the auxiliary plate 405 can be directly separated without destructive disassembly, and the internal components can be quickly accessed; after maintenance is completed, the plates are reassembled to restore the flow guiding function of the water channel 4063, and the next round of work can be started.
