Description

Technical Field

[0001] This invention relates to the field of fecal treatment technology, specifically to a fecal composting, fertilization, and irrigation device capable of gas-solid separation. Background Technology

[0002] Fecal sewage is generally collected and pretreated using physical methods, which involves using mechanical equipment to remove solids and water from the sewage, or treating it to render it harmless before using it as organic fertilizer for landscaping. The treated sewage is then discharged into municipal sewage treatment plants for further treatment.

[0003] In the prior art, such as the Chinese Publication No. CN109354515A, "A device and method for treating human and animal excrement" includes the following steps: S1. Preparing biochar; S2. Using biochar to adsorb and filter water from human and animal excrement; S3. Introducing the biochar after adsorption in step S2 into microbial fermentation; S4. Drying and pulverizing the mixture of biochar and excrement obtained in step S3 to prepare organic fertilizer; storing the water separated in step S2; S5. Promoting the biochar and stored filtered water from step S4 to fertilize farmland. This device separates and treats excrement, which not only improves the separation efficiency of excrement but also reduces the amount of biochar used. Adding a deodorizing agent to the excrement deodorizes it, and adding microbial fermentation increases the bacterial content of the excrement, thus increasing the soil fertility of the excrement biochar fertilizer.

[0004] Currently, most manure composting and irrigation devices rely on single biochar adsorption or fixed filter separation, without a dynamic adjustment mechanism designed to address the differences in manure characteristics (moisture content, particle size). For example, pig farm manure (70%-85% moisture content, high fiber content) easily clogs biochar pores or fixed filters, leading to a sharp drop in filtration efficiency. Chicken farm manure (50%-65% moisture content, high fine particle content) suffers from insufficient adsorption, resulting in fine particles being lost with the filtrate. The solid-liquid properties fluctuate greatly after separation, easily causing blockages in the separation equipment and increasing maintenance costs. Furthermore, existing technologies rely on single filtration or gravity sedimentation, which is insufficient for separating fine particles (e.g., <10μm particle size). Therefore, a novel gas-solid separation manure composting and irrigation device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a gas-solid separation manure composting, fertilization, and irrigation device to solve the problems mentioned in the background art. Existing technologies mostly use single biochar adsorption or fixed filter screen separation, without designing a dynamic adjustment mechanism for the differences in manure characteristics (moisture content, particle size), which easily leads to clogging of the separation equipment, resulting in increased maintenance costs. Moreover, existing technologies rely on single filtration or gravity sedimentation, which has insufficient separation capacity for fine particles (such as <10μm particle size).

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas-solid separation manure composting, fertilization, and irrigation device, comprising a pretreatment component, a filter screen separation component, a pre-drying component, and a gas-solid separator; the pretreatment component is installed on top of the filter screen separation component and is used to homogenize manure with different characteristics; the filter screen separation component is used to receive the manure from the pretreatment component.

[0008] The waveform filter further includes a shape memory alloy adjustable electrical telescopic column, a mesh diameter end, an adjusting slide, and an inner sliding groove. The shape memory alloy adjustable electrical telescopic column is made of shape memory alloy material and can dynamically adjust the pore size of the waveform filter according to the particle characteristics of the homogenized material. The side end of the shape memory alloy adjustable electrical telescopic column is connected to the adjusting slide. The adjusting slide forms an opposing sliding within the inner sliding groove, which is located inside the mesh diameter end.

[0009] The ultrasonic cleaner is configured to correspond with the waveform filter, and can perform ultrasonic vibration cleaning on the surface of the waveform filter in stages.

[0010] The gas-solid separator is a cyclone composite separator, with a pneumatic conveying device installed on its top. Its inlet is connected to the pneumatic outlet in the pre-drying component, and it is used to perform secondary gas-solid separation on the material after separation by the waveform filter screen.

[0011] The solid outlet of the gas-solid separator is connected to a fertilizer application hose, which is used to transport the separated solid organic fertilizer to the area to be fertilized.

[0012] Preferably, the filter separation assembly further includes a reciprocating drive structure, the side end of which is connected to a partition groove, and the waveform filter screen is installed inside the partition groove to form different classification filtration areas.

[0013] Preferably, an annular guide rail is provided at the top of the partition groove, and a positioning slide seat is slidably connected inside the annular guide rail. A small shaft arm is installed at the side end of the positioning slide seat, and a cleaning structure is installed at the end of the small shaft arm.

[0014] Preferably, the pretreatment component includes a mounting frame, an annular guide rail is installed inside the frame of the mounting frame, a drive variable frequency motor is installed on the frame of the mounting frame, the output end of the drive variable frequency motor is connected to a stator and rotor structure, the center end of the stator and rotor structure is connected to a rotating shaft, a lead screw is integrally formed on the side end of the rotating shaft, and guide keys are installed at the left and right ends of the lead screw.

[0015] Preferably, an electromagnetic stopper is fitted around the lead screw shaft and guide key, and a stirring blade dispersing structure is installed around the electromagnetic stopper. A gear ring is fitted around the first processing chamber.

[0016] Preferably, the pre-drying assembly includes a conical guide cylinder, and the side valve port of the conical guide cylinder is connected to a horizontal feed cylinder.

[0017] Preferably, the side end of the horizontal feed cylinder is connected to a discharge end, the discharge end has an inclined guide structure, and the bottom of the side end of the discharge end is connected to a filter press cylinder.

[0018] Preferably, the gas-solid separator consists of a coarse separator and a fine separator, and the bottom of the gas-solid separator is connected to a sedimentation chamber.

[0019] Preferably, the inlet of the coarse separator and the fine separator are respectively provided with angle-adjustable guide vanes, and the size of the angle-adjustable guide vanes is different, so that the airflow swirl intensity can be changed by adjusting the angle of the guide vanes.

[0020] Preferably, both the sedimentation chamber and the gas-solid separator are connected to a discharge connection end on their sides, and the discharge connection end is connected to the fertilizer application hose.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, with the cooperation of the filter screen separation component, the homogenized feces fall onto the waveform filter screen in the separating groove. At this time, the reciprocating drive structure is activated, causing the separating groove to slide back and forth, so that the material is evenly spread on the surface of the filter screen. The particle detection sensor on the surface of each filter section detects the particle size in real time and transmits the signal to the control structure of the current guiding control battery. The control structure adjusts the shape memory alloy adjustable electric telescopic column accordingly: if the particles are coarse, the power is turned on to extend the shape memory alloy adjustable electric telescopic column, pushing the adjusting slide along the inner sliding groove to reduce the mesh size and achieve interception; if the particles are fine, the power is turned off to contract the shape memory alloy adjustable electric telescopic column to expand the mesh size and allow them to pass through. The mesh size of each filter section is adjusted independently. Achieving precise adaptation, the particle detection sensor continuously monitors and dynamically adjusts the mesh size to maintain optimal filtration efficiency. As the separating tank slides back and forth, the material tumbles on the corrugated filter screen. Liquid and fine particles seep into the bottom of the separating tank through the mesh. Solid particles trapped in different filtration sections gather to both sides under inertia and fall into the corresponding conical material cylinders, respectively exporting coarse and fine particles to the pre-drying component for graded processing. The overall dynamic adaptability is strong, compatible with different particle characteristics, and the separation efficiency and accuracy are high. The reciprocating sliding material tumbling reduces the static adhesion of sticky particles on the filter screen surface. Combined with the dynamic deformation of the mesh, it reduces the risk of clogging from the source, significantly reducing downtime maintenance time and labor costs.

[0023] 2. In this invention, with the cooperation of the filter screen separation component, when the waveform filter screen works for a certain period of time or the surface adhesion increases, the control structure starts the cleaning program. The positioning sliding seat slides along the annular guide rail, driving the small shaft arm and the cleaning structure to move. The arc-shaped scraper of the cleaning structure adheres to the wave surface of the filter screen to scrape off the sticky material. At the same time, the ultrasonic cleaner is started, and the fine adhering material is removed from the filter screen and falls into the conical material cylinder through high-frequency vibration. If the adhesion in a certain section is serious, multiple cleanings can be performed. During the frequent adjustment of the shape memory alloy adjustable electric telescopic column, the air-cooled spray cooling nozzle is started at a preset interval, spraying room temperature compressed air to the shape memory alloy adjustable electric telescopic column and the surface of the filter screen to dissipate heat. If the temperature is too high, a small amount of water mist is sprayed simultaneously to enhance cooling, ensuring that the entire filter screen separation process is efficient and stable. This solves the limitation of traditional equipment in adapting to a single material and significantly improves the utilization rate of organic fertilizer resources. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In an embodiment of the present invention, reference is made to Figure 1 and Figure 10As shown: A manure composting, fertilization and irrigation device with gas-solid separation capability includes a pretreatment component 100, a filter screen separation component 200, a pre-drying component 300 and a gas-solid separator 400; the pretreatment component 100 is installed on top of the filter screen separation component 200 and is used to homogenize manure with different characteristics; the filter screen separation component 200 is used to receive and separate the manure from the pretreatment component 100.

[0038] The gas-solid separator 400 is a cyclone composite separator, and a pneumatic conveying device 700 is installed on its top. Its inlet is connected to the pneumatic outlet 311 in the pre-drying component 300, which is used to perform secondary gas-solid separation on the material separated by the waveform filter screen.

[0039] The solid outlet of the gas-solid separator 400 is connected to a fertilizer application hose, which is used to transport the separated solid organic fertilizer to the area to be fertilized.

[0040] In this embodiment, specifically: First, the operator can pour pig farm manure (high moisture, large particles) and chicken farm manure (dry, small particles) into the pretreatment component 100 for processing, making the initial characteristics of the mixture easier to unify. Then, the homogeneous material enters the filter separation component 200 from the pretreatment component 100, and the filter separation component 200 performs separation and filtration on the received manure. Next, the solid material separated by the filter enters the pre-drying component 300 to dry the manure material after pretreatment and separation and filtration. Subsequently, the dried loose particles are carried by the airflow through the pneumatic conveying device 700 into the gas-solid separator 400 for secondary gas-solid separation.

[0041] In some embodiments, according to Figure 1 and Figures 5-9 As shown, the filter separation assembly 200 includes a wave-shaped filter and an ultrasonic cleaner 212. A particle detection sensor is installed on the surface of the wave-shaped filter to detect the particle size distribution of the homogenized material. The wave-shaped filter is made of stainless steel with a corrugated mesh surface. The mesh surface can be divided into 3-4 independent filter sections along the length direction (each section corresponds to a different mesh size range). The mesh of each filter section consists of a mesh diameter end 206 and a sliding adjustment slide 213. An inner groove 214 is opened inside the mesh diameter end 206. The adjustment slide 213 is embedded in the inner groove 214 and can slide along the groove. By changing the relative position of the adjustment slide 213 and the mesh diameter end 206, the mesh size can be dynamically adjusted. The particle detection sensors are evenly distributed on the surface of each filter section of the wave-shaped filter (e.g., 2-3 per section) and can detect the size and distribution of the material particles flowing through the section in real time. The detection signal is transmitted to the control structure of the current guiding control battery 207 through a wire, providing a basis for the adjustment of the shape memory alloy adjustable electric telescopic column 215.

[0042] The waveform filter further includes a shape memory alloy adjustable electrical telescopic column 215, a mesh diameter end 206, an adjusting slide 213, and an inner groove 214. The shape memory alloy adjustable electrical telescopic column 215 is made of shape memory alloy material and can dynamically adjust the pore size of the waveform filter according to the particle characteristics of the homogenized material. The side end of the shape memory alloy adjustable electrical telescopic column 215 is connected to the adjusting slide 213. The adjusting slide 213 forms an opposing sliding inside the inner groove 214. The inner groove 214 is opened inside the mesh diameter end 206. The shape memory alloy adjustable electrical telescopic column 215 is made of Ni-Ti shape memory alloy and is connected to the current control battery 207 through a wire. The temperature change can be controlled by switching the power on and off. When the power is on, the alloy is heated and elongated, pushing the adjusting slide to slide outward along the inner groove 214 (the mesh size shrinks). When the power is off, the alloy cools and contracts, pulling the adjusting slide inward (the mesh size expands), thereby adapting to materials with different particle sizes.

[0043] The ultrasonic cleaner 212 is configured to correspond to the waveform filter screen, and can perform ultrasonic vibration cleaning on the surface of the waveform filter screen in stages.

[0044] The filter separation assembly 200 further includes a reciprocating drive structure 201. A partition groove 203 is connected to the side end of the reciprocating drive structure 201. A wave-shaped filter screen is installed inside the partition groove 203 to form different classification filtration areas. A conical material cylinder 202 is slidably connected to the bottom of the partition groove 203. A rotating column 208 is rotatably connected to the top side surface of the conical material cylinder 202. The rotating column 208 is used to drive the partition groove 203 to slide back and forth under the driving action of the reciprocating drive structure 201. A current guiding control battery 207 is installed on the side end of the partition groove 203. The current guiding control battery 207 is connected to the side end electrical connection point of the shape memory alloy adjustable electrical telescopic column 215 through a circuit.

[0045] An annular guide rail 204 is provided at the top of the partition groove 203. A positioning sliding seat 209 is slidably connected inside the annular guide rail 204. A small shaft arm 210 is installed on the side end of the positioning sliding seat 209. A cleaning structure 211 is installed at the end of the small shaft arm 210. An ultrasonic cleaner 212 is installed outside the cleaning structure 211 and moves synchronously with the movement of the cleaning structure 211. Air-cooled spray cooling nozzles 205 are evenly installed on the annular edge of the annular guide rail 204. The nozzles in the air-cooled spray cooling nozzles 205 are tilted downwards and aimed at the filter section of the waveform filter screen. They can spray room temperature compressed air and a small amount of water mist (droplet diameter <10μm) to cool the shape memory alloy adjustable electric telescopic column 215 (which is adjusted in conjunction with the sliding of the adjustable electric telescopic column 215 to drive the sliding of the adjusting slide 213). At the same time, it can also help remove small adhering substances on the surface of the filter screen.

[0046] In this embodiment, specifically: First, the material (moist and granular) homogenized by the pretreatment component 100 enters the filter screen separation component 200 through the discharge port 120 and falls onto the corrugated filter screen in the partition groove 203. At this time, the reciprocating drive structure 201 is started, and the partition groove 203 is driven to slide back and forth through the eccentric wheel and connecting rod, so that the material is evenly spread on the surface of the corrugated filter screen (avoiding local accumulation).

[0047] Next, the particle detection sensors on the surface of each filter section start working, detecting the size of the material particles flowing through the area in real time (e.g., the particles detected in one section are mostly 3-5mm, while the particles detected in another section are mostly 1-2mm), and converting the detection results into electrical signals that are transmitted to the control structure of the flow control battery 207.

[0048] Secondly, the control structure of the current-guiding control battery 207 analyzes the signals of each sensor. If the particles in a certain filter section are mainly coarse particles (4mm), the control structure energizes the shape memory alloy adjustable electric telescopic column 215 of that section. The shape memory alloy adjustable electric telescopic column 215 is heated and elongated, pushing the adjusting slide 213 to slide outward along the inner slide groove 214. The relative distance between the mesh diameter end 206 and the adjusting slide 213 decreases, and the mesh size is shortened (e.g., reduced from 5mm to 2mm), preventing coarse particles from falling.

[0049] Next, if the particles in a certain filter section are mainly fine particles (e.g., <2mm), the control structure cuts off the power supply to the memory alloy adjustable electric telescopic column 215 in that section, and sprays cooling mist to this section through the air-cooled spray nozzle 205, causing the memory alloy adjustable electric telescopic column 215 inside the section to cool and contract, pulling the adjusting slide 213 to slide inward, thus expanding the mesh (e.g., from 2mm to 5mm), ensuring that the particles are effectively dropped and the coarse particles are intercepted. The mesh of each filter section can be adjusted independently to achieve precise adaptation of one section and one hole.

[0050] Subsequently, during the material filtration process, the particle detection sensor continuously monitors the process. If the particle characteristics change (such as a sudden increase in the proportion of coarse particles), the control structure adjusts the power on / off state of the telescopic column in real time, dynamically changing the mesh size to always maintain the best filtration efficiency.

[0051] As the partition trough 203 slides back and forth, the material tumbles back and forth on the corrugated filter screen, and the liquid and fine particles (smaller than the mesh size) seep through the mesh into the bottom of the partition trough 203 below.

[0052] Next, the solid particles trapped by different filtration sections (coarse particles are trapped by the large mesh section and fine particles are trapped by the small mesh section) gather on both sides of the partition groove 203 under the inertia of reciprocating sliding, and finally fall into the corresponding conical barrel 202.

[0053] Subsequently, the grading outlet of the conical cylinder 202 sequentially discharges solid particles of different sizes. For example, coarse particles (such as 5-10mm) first enter the pre-drying component 300, followed by fine particles (such as 1-5mm), thus achieving particle grading.

[0054] Subsequently, when the waveform filter works for a certain period of time (e.g., 30 minutes) or the particle detection sensor detects an increase in adhesion on the surface of the waveform filter, the control structure starts the cleaning program, causing the positioning slide seat 209 to slide along the annular guide rail 204, driving the small shaft arm 210 and the cleaning structure 211 to move.

[0055] Next, the arc-shaped scraper of the cleaning structure 211 fits against the wavy surface of the corrugated filter screen and moves from one end of the filter screen to the other with the sliding seat, scraping off the sticky material accumulated on the surface. At the same time, the ultrasonic cleaner 212 is activated, and the high-frequency vibration generated by it is transmitted to the corrugated filter screen through the scraper, causing fine adhering objects (such as fine particles embedded in the mesh) to detach from the corrugated filter screen and fall into the conical barrel 202 along with the scraped material.

[0056] After the cleaning structure completes a full-area cleaning, the positioning slide seat 209 returns to its initial position. If a certain filter section is particularly heavily coated, the control structure can control the positioning slide seat 209 to drive the small shaft arm 210 and the cleaning structure 211 to clean that section multiple times (e.g., 2-3 times).

[0057] During the frequent adjustment (power on and off) of the shape memory alloy adjustable electrical telescopic column 215, the air-cooled spray cooling nozzle 205 is activated at a preset interval (once every 10 minutes) to spray room temperature compressed air onto the shape memory alloy adjustable electrical telescopic column 215 and the surface of the waveform filter screen, thereby removing the heat from the shape memory alloy adjustable electrical telescopic column 215 (to avoid continuous high temperature affecting its shape memory performance).

[0058] Next, if the temperature of the shape memory alloy adjustable electrical telescopic column 215 is detected to be too high (e.g., exceeding 80°C), the nozzle will simultaneously spray a small amount of water mist (the mist droplets evaporate rapidly and absorb heat) to enhance the cooling effect and ensure that the shape memory alloy adjustable electrical telescopic column 215 is always within the optimal operating temperature range (50-70°C).

[0059] When the homogenized feces fall onto the corrugated filter screen in the separating tank 203, the reciprocating drive structure 201 starts, causing the separating tank 203 to slide back and forth, so that the material is evenly spread on the surface of the filter screen. The particle detection sensors on the surface of each filter section detect the size of the material particles in real time and transmit the signal to the control structure of the flow control battery 207. The control structure adjusts the shape memory alloy adjustable electric telescopic column 215 accordingly: if it is a coarse particle, it is energized to extend the shape memory alloy adjustable electric telescopic column 215, pushing the adjusting slide 213 to slide along the inner slide groove 214 to reduce the mesh size and achieve interception; if it is a fine particle, it is de-energized to contract the shape memory alloy adjustable electric telescopic column 215 to expand the mesh size and allow it to pass through. The mesh size of each filter section is adjusted independently to achieve precise adaptation, and the particle detection sensors continuously monitor and dynamically adjust the mesh size to maintain the best filtration efficiency. As the separating tank 203 slides back and forth, the material tumbles back and forth on the corrugated filter screen. Liquid and fine particles seep into the bottom of the separating tank 203 through the mesh. Solid particles trapped in the filtration section gather to both sides under inertia and fall into the corresponding conical material cylinder 202. Coarse and fine particles are respectively discharged to the pre-drying component 300 for graded treatment. When the wave-shaped filter screen works for a certain period of time or the surface adhesion increases, the control structure starts the cleaning program. The positioning sliding seat 209 slides along the annular guide rail 204, driving the small shaft arm 210 and the cleaning structure 211 to move. The arc-shaped scraper of the cleaning structure 211 scrapes off the sticky material from the wave surface of the filter screen. At the same time, the ultrasonic cleaner 212 starts, using high-frequency vibration to make the fine adhering objects detach from the filter screen and fall into the conical material cylinder 202. If the adhesion in a certain section is serious, multiple cleanings can be performed. During the frequent adjustment of the shape memory alloy adjustable electric telescopic column 215, the air-cooled spray cooling nozzle 205 starts at a preset interval, spraying room temperature compressed air to the shape memory alloy adjustable electric telescopic column 215 and the filter screen surface for heat dissipation. If the temperature is too high, a small amount of water mist is sprayed simultaneously to enhance cooling, ensuring that the entire filter screen separation process is efficient and stable.

[0060] In some embodiments, according to Figures 1-4As shown, the pretreatment assembly 100 includes a mounting frame 101, an annular guide rail 204 is installed inside the frame of the mounting frame 101, a drive variable frequency motor 102 is installed on the frame of the mounting frame 101, the output end of the drive variable frequency motor 102 is connected to a stator and rotor structure 104, a first processing chamber 107 is connected to the outside of the stator and rotor structure 104, a second conical processing chamber 118 is installed inside the first processing chamber 107, and a first feed is installed at the top of the first processing chamber 107 and the second conical processing chamber 118 respectively. The bottom of the first processing chamber 107 and the second conical processing chamber 118 are both provided with discharge ports 120. A solid-liquid separator is provided at the bottom side of the second conical processing chamber 118. Spray mist discs 121 and liquid inlet structures 105 are respectively provided at the left and right sides of the stator-rotor structure 104. A rotating shaft 113 is connected to the center end of the stator-rotor structure 104. A lead screw shaft 114 is integrally formed at the side end of the rotating shaft 113. Guide keys 115 are provided at the left and right ends of the lead screw shaft 114.

[0061] An electromagnetic stopper 116 is fitted around the lead screw shaft 114 and the guide key 115. A stirring blade dispersing structure 117 is installed around the electromagnetic stopper 116. A gear ring 112 is fitted around the first processing chamber 107. An electromagnetic stopper synchronous belt structure 103 is connected to the output end of the drive variable frequency motor 102. A synchronous shaft 106 is connected to the top output end of the electromagnetic stopper synchronous belt structure 103. A drive gear 119 is installed on the side end of the synchronous shaft 106. The drive gear 119 and the gear ring 112 are meshed together. A buffer spring 110 is installed on the side end of the mounting bracket 101. A swing support frame 111 is connected to the side end of the buffer spring 110. The exterior of the second cone processing chamber 118 is located inside the swing support frame 111.

[0062] In this embodiment, specifically: the operator can pour pig farm manure (high moisture, large particles) and chicken farm manure (dry, small particles) into the pretreatment component 100 respectively, entering from the first feed inlet 108 and the second feed inlet 109 respectively. Then, the drive variable frequency motor 102 drives the synchronous shaft 106 to rotate through the electromagnetic blocking synchronous belt structure 103. The drive gear 119 on the synchronous shaft 106 meshes with the gear ring 112 of the first treatment chamber 107, causing the first treatment chamber 107 to rotate slowly around its own axis. At the same time, the rotating shaft 113 drives the lead screw shaft 114 and the stirring blade dispersing structure 117 to rotate (which can be in the opposite direction to the first treatment chamber 107).

[0063] Secondly, the dried chicken manure enters the first processing chamber 107 through the first feed inlet 108. As the first processing chamber 107 rotates, the convex ridges on the inner wall drive the manure to move in a circular motion. At the same time, the stirring blades on the outside of the second conical processing chamber 118 shear and tear the coarse fiber clumps (such as undigested straw) in the manure, and break them into preliminary fragments. During the crushing process, the free water in the manure seeps out due to the stirring and flows down the wall of the processing chamber to the bottom.

[0064] Subsequently, the high-moisture manure from the pig farm enters the second conical processing chamber 118 through the second feed inlet 109, causing the second conical processing chamber 118 to slide downwards along the conical wall. At the same time, the arc-shaped blades of the stirring and dispersing structure 117 rotate from the center, causing the dry clumps (such as coagulated urate hard lumps) to be initially loosened into particles with a diameter ≤15mm. When the loosened particles reach the bottom of the cone, they are filtered by the solid-liquid separator. Unloosened hard lumps are intercepted (subsequently manually cleaned), and qualified particles enter the first processing chamber 107 through the discharge outlet 120 to mix with the pig farm manure.

[0065] Then, in the second cone processing chamber 118, the pig farm's high-moisture manure is processed. At this time, the rotating shaft 113 drives the lead screw shaft 114 to rotate, and the guide key 115 forces the electromagnetic blocker 116 and the stirring blade dispersing structure 117 to move back and forth along the axial direction. This causes the stirring blade dispersing structure 117 to compress the material when it moves to the left and to stretch the material when it moves to the right, so that the pig farm's high-moisture manure is fully dispersed.

[0066] During this process, the stator and rotor structure 104 begins to work: the rotor rotates with the rotating shaft 113, generating high-speed relative motion with the teeth of the stator, causing the second cone processing chamber 118 to rotate.

[0067] Among them, the swing support frame 111, in cooperation with the reciprocating drive structure 201, drives the partition groove and the waveform filter screen to swing slightly. With the buffering and shock absorption effect of the buffer spring 110, the material on the surface of the waveform filter screen will move irregularly, thereby enhancing the separation and filtration effect.

[0068] Afterwards, the operator can observe the moisture content of the manure through the observation window: if the material is too wet due to the high proportion of manure in the pig farm, the aforementioned rotating shaft 113 drives the lead screw shaft 114 to rotate, and the guide key 115 forces the electromagnetic stopper 116 and the stirring blade dispersing structure 117 to move back and forth along the axial direction, so that when the stirring blade dispersing structure 117 moves to the left, it compresses the material, and when it moves to the right, it stretches the material, so that the high moisture content of the pig farm manure is fully dispersed and filtered.

[0069] Next, if the material is too dry (easily crumbles when squeezed by hand, and has no stickiness) due to the high proportion of chicken farm manure, the liquid inlet structure 105 sprays fine water mist through the spray mist plate 121. The water mist fully contacts the rotating material, replenishing the moisture to a state where it can be shaped by hand or crumbles easily when gently kneaded. During the spraying process, the electromagnetic interruptor 116 can stop the axial movement of the stirring blade by cutting off the power, only maintaining rotation, so that the water mist is evenly attached to the surface of the chicken farm manure.

[0070] Next, the homogenized material falls through the discharge port 120 at the bottom of the first processing chamber 107 and the second conical processing chamber 118, respectively, so that the material falls onto the surface of the wave-shaped filter screen of the filter screen separation assembly 200.

[0071] In some embodiments, according to Figure 1 and Figure 11 As shown, the pre-drying assembly 300 includes a conical guide cylinder 301. A horizontal guide cylinder 302 is connected to the side valve port of the conical guide cylinder 301. A drive energy-saving motor 306 is installed on the side end of the horizontal guide cylinder 302. A spiral extrusion structure 304 is connected to the output end of the drive energy-saving motor 306. The spiral extrusion structure 304 is configured with a large front diameter and a small rear diameter. A water filter cylinder 305 is sleeved on the outside of the spiral extrusion structure 304. A drying rake structure 303 is connected to the side end of the spiral extrusion structure 304.

[0072] The side end of the horizontal feed cylinder 302 is connected to the discharge end 310, which has an oblique guide structure. The bottom of the side end of the discharge end 310 is connected to the filter cylinder. The internal piston of the filter cylinder is connected to the filter element 309. The side end of the filter element 309 is connected to the gear rack 308. The output end of the drive energy-saving motor 306 is externally fitted with a synchronous connecting belt 307. The output end of the synchronous connecting belt 307 is connected to the gear in the gear rack 308, and a secondary electromagnetic blocker is installed at its connection end. The discharge end 310 is connected to the top of the connection end of the filter cylinder and the pneumatic outlet 311.

[0073] In an embodiment of the present invention, specifically: First, the solid feces separated by the filter screen enter the conical guide cylinder 301 from the conical material cylinder 202 and slide along the inner wall to the bottom. The valve of the conical guide cylinder 301 is dynamically opened and closed according to the amount of material in the horizontal guide cylinder 302 (e.g., the valve is opened wider when there is less material inside and closed narrower when there is more material), to ensure uniform feeding and avoid overloading of the horizontal guide cylinder 302.

[0074] Next, the material enters the horizontal feed cylinder 302 through the side valve port of the conical guide cylinder 301, driving the energy-saving motor 306 to start (speed 80 rpm), which in turn drives the spiral extrusion structure 304 and the drying rake structure 303 to rotate. This allows the material to first undergo drying operations through the drying rake structure 303, where the rotation of the drying rake structure 303 breaks up material clumps into particles with a diameter ≤5mm. During this breaking-up process, the friction between the rake blades and the material and the cylinder wall generates slight heat (40-50℃), which is then combined with… Natural ventilation within the horizontal feed cylinder 302 further evaporates surface moisture from the particles, reducing the moisture content to 60%-55%. Then, the screw extrusion structure 304 uses the front section (small diameter, narrow pitch; large diameter, wide pitch) of the blades to spread the material, preventing localized accumulation. The rear section (large diameter, wide pitch) of the blades gradually compresses the material, squeezing out free water (which flows out from the filter cylinder 305). At this point, the material's moisture content drops to 35%-45%, forming semi-dry lumps. Afterwards... As the spiral extrusion structure 304 continues to rotate, the material enters the filter press cylinder through the bottom channel of the discharge end 310. At this time, the secondary electromagnetic interruptor is energized, and the synchronous connecting belt 307 transmits the motor power to the gear rack 308. The gear rotates, driving the rack to push the filter press element 309 to move towards the end of the filter press cylinder, performing secondary extrusion on the material (e.g., pressure of 0.3-0.5MPa), squeezing out residual moisture (at this time, the moisture content drops to 25%-30%). The squeezed water flows out along the filter holes at the bottom of the filter press cylinder for collection. Then, after the filtration is completed, the secondary electromagnetic interruptor is de-energized, and the filter press element 309 returns to its initial position, so that the dry particles (moisture content 25%-30%) in the discharge end 310 (in a loose state) are sucked into the conveying pipe under the negative pressure of the pneumatic outlet 311. The larger particles enter the pipe first due to the synergistic effect of gravity and airflow, while the smaller particles follow with the airflow, forming a continuous and stable material flow, which is then conveyed to the gas-solid separator 400 for further processing.

[0075] In some embodiments, according to Figure 1 and Figure 10 As shown, the gas-solid separator 400 consists of a coarse separator and a fine separator, and the bottom of the gas-solid separator 400 is connected to a sedimentation chamber 500.

[0076] The coarse separator and the fine separator are equipped with angle-adjustable guide vanes at their inlets, and the size of the angle-adjustable guide vanes is different, so that the airflow swirl intensity can be changed by adjusting the angle of the guide vanes.

[0077] Both the sedimentation chamber 500 and the gas-solid separator 400 are connected to a discharge connection end 600 on their side, and the discharge connection end 600 is connected to the fertilizer application hose.

[0078] In specific embodiments of the present invention: First, the pre-dried loose particles (moisture content 25%-30%) enter the main pipe of the gas-solid separator 400 under the negative pressure of the pneumatic outlet 311. The pipe naturally divides the flow according to the particle size, so that coarse particles with a diameter ≥5mm enter the coarse separator first due to their greater inertia, while medium and fine particles with a diameter of 1-5mm are turned by the airflow and enter the fine separator. When the coarse particles enter the coarse separator, the large guide vanes at the inlet guide the airflow to rotate tangentially at a preset angle (e.g., 30°), forming a strong swirling flow field. This causes the coarse particles to be thrown against the cylinder wall under the action of centrifugal force and slide down the inner wall to the bottom conical discharge port. During the process, the spiral guide ribs assist in guiding the flow of particles and prevent them from accumulating in corners. If it is detected that the separation of coarse particles is incomplete (e.g., there are still large particles in the outlet airflow), the vane angle can be increased by adjusting the mechanism (e.g., to 40°) to enhance the swirling intensity.

[0079] Afterwards, medium and fine particles enter the fine separator. Small guide vanes at the inlet guide the airflow to rotate at a small angle (e.g., 20°). The swirling intensity is weaker than that of the coarse separator (to avoid fine particles being excessively thrown against the wall and causing rebound). The medium and fine particles are separated under moderate centrifugal force and slide down the spiral guide ribs on the inner wall to the bottom discharge port. If the proportion of fine particles is high (e.g., when treating chicken manure), the vane angle can be adjusted to a smaller angle (e.g., 15°) to reduce energy consumption while ensuring separation efficiency.

[0080] The remaining particles then fall into the sedimentation chamber 500.

[0081] Finally, the coarse particles from the coarse separator, the medium and fine particles from the fine separator, and the particles from the sedimentation chamber 500 enter the discharge connection end 600 through their respective discharge ports. This ensures that the one-way valve ensures that the material can only flow towards the fertilizer hose, preventing backflow of air. The filter screen at the quick-connect joint finally intercepts any remaining extremely fine particles. The pure solid organic fertilizer particles are then transported to the fertilization area through the fertilizer hose, completing the entire gas-solid separation process.

[0082] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
