A continuous biogas slurry drip irrigation and fertilization device

Abstract

This invention discloses a continuous biogas slurry drip irrigation fertilization device, relating to the field of biogas slurry drip irrigation technology. This invention alters the flow direction of the biogas slurry by intermittently operating the left and right suction chambers, thereby automatically removing deposits from the mesh plate. When the left suction chamber is operating, biogas slurry flows unidirectionally from the sedimentation chamber and the right suction chamber through mesh plates one and two, forming a stable deposit layer on the outer side of mesh plate one. When switching states, the left suction chamber stops absorbing liquid while the right suction chamber is operating, and the biogas slurry in the sedimentation chamber is redirected to the right suction chamber, creating a new flow direction. This results in a pressure difference across mesh plate one. The pressure in the sedimentation chamber briefly increases due to the change in flow path, concentrating the flow velocity in the right suction chamber. The pressure in the left suction chamber approaches static due to the lack of liquid absorption, causing large impurities to detach because their adhesion is less than the shear force generated by the pressure difference. This automatically cleans the deposits on the outer side of mesh plate one, ensuring stable and continuous biogas slurry drip irrigation.

Description

Technical Field

[0001] This invention relates to the field of biogas slurry drip irrigation technology, specifically a continuous biogas slurry drip irrigation fertilization device. Background Technology

[0002] The biogas slurry drip irrigation fertilization device is an agricultural equipment that precisely delivers biogas slurry to the root zone of crops through a drip irrigation system. Its core design combines filtration, aeration, fertilizer mixing, and drip irrigation technologies, offering multiple advantages such as improved fertilizer utilization, reduced environmental pollution, and promoted crop growth. The biogas slurry storage and filtration system consists of a household biogas digester and a plastic bucket filtration tank. The filtration tank serves as a biogas slurry storage tank, integrating with irrigation fertilization and water collection for drought resistance, achieving multiple uses from a single tank. Biogas slurry is a liquefied fertilizer with small molecules that are easily absorbed. The drip irrigation method further reduces nutrient volatilization and loss, improving fertilizer utilization compared to traditional fertilization. Biogas slurry can replace chemical fertilizers, reducing nitrate content and increasing vitamin C content in vegetables, achieving harmony between organic farming and environmental protection. Drip irrigation technology reduces soil compaction and surface runoff, creating an optimal growth environment for crop roots. The organic matter and microorganisms in the biogas slurry can improve soil structure and enhance crop disease resistance.

[0003] In existing biogas slurry drip irrigation systems, the biogas slurry is transported to a treatment tank for processing. However, current methods involve one-way transport of the slurry within the tank, causing a large amount of debris to adhere to the filter screen. Since biogas slurry contains a significant amount of suspended solids, this one-way transport leads to the continuous accumulation of debris on the screen surface, forming a dense filter cake layer. If not cleaned promptly, the increased thickness of the filter cake layer can completely clog the screen pores, causing a sudden increase in system pressure. This can lead to drip tape bursting or pump overload damage. The clogged screen also causes fluctuations in biogas slurry delivery, resulting in inconsistent drip tape pressure. Crop roots cannot continuously absorb nutrients and water. In clogged areas, reduced water output from the drippers leads to stunted crop growth due to nutrient and water deficiencies, while in unclogged areas, excessive fertilization can cause root burn. Summary of the Invention

[0004] Technical problems to be solved This invention provides a continuous biogas slurry drip irrigation fertilization device, which solves the problem of debris adhering to the internal mesh plate of the biogas slurry drip irrigation fertilization device and is difficult to clean automatically.

[0005] Technical solution To achieve the goal of automatically cleaning debris adhering to the mesh plates inside the biogas slurry drip irrigation fertilization device, the present invention achieves this through the following technical solution: A continuous biogas slurry drip irrigation fertilization device includes a biogas slurry drip irrigation treatment tank, a left suction chamber and a right suction chamber are opened inside the biogas slurry drip irrigation treatment tank, a sedimentation chamber is opened inside the biogas slurry drip irrigation treatment tank, and two partitions are installed inside the biogas slurry drip irrigation treatment tank. A mesh plate one and a mesh plate two are installed on the inner walls of both partitions. The biogas slurry drip irrigation treatment tank includes a counter-current pumping assembly, two floating assemblies, two anti-clogging assemblies, and two accelerating assemblies. The anti-clogging assembly includes a telescopic water pipe and a protective sleeve. The telescopic water pipe is installed on the outer surface of the counter-current pumping assembly, and the protective sleeve is installed on the outer surface of the telescopic water pipe. The protective sleeve has a cavity inside. The outer surface of the protective sleeve has a number of evenly distributed mesh holes, and the inner surface of the protective sleeve has a number of evenly distributed mesh holes. The opposing suction components alternately draw biogas slurry from the left and right suction chambers. The alternating operation of the left and right suction chambers creates a periodic flow of biogas slurry, keeping impurities suspended in the flow. When the right suction chamber is drawing slurry, the left suction chamber flows in the opposite direction, creating a push-pull effect that prevents impurities from adhering to the screen plate. The floating component adjusts the height of the protective sleeve according to the liquid level in the biogas slurry drip irrigation tank, placing the protective sleeve below the liquid surface to avoid high-concentration scum and sediment, and directly drawing in clear liquid with low impurities and high nutrients. The accelerating component accelerates the flow of biogas slurry, thereby providing power to the anti-clogging component, which prevents the protective sleeve from becoming clogged.

[0006] Furthermore, the anti-blocking component also includes a limiting ring groove and a limiting slip ring. The limiting ring groove is opened inside the protective sleeve, and the limiting slip ring is movably installed on the inner wall of the limiting ring groove. Several scraper blades are evenly distributed and installed on the bottom surface of the limiting slip ring, and several scraper blades are evenly distributed and installed on the bottom surface of the limiting slip ring.

[0007] Furthermore, the outer surfaces of several scraper blades one are in contact with the inner wall of the cavity, the outer surfaces of several scraper blades two are in contact with the outer surface of the protective sleeve, and several connecting posts are evenly distributed on the top surface of the limiting slip ring, and ball stop shafts are installed on the top surface of each of the connecting posts.

[0008] Furthermore, the acceleration assembly includes an acceleration liquid shell plate and an inlet chamber. The acceleration liquid shell plate is installed on the outer surface of the partition plate, and the acceleration liquid shell plate is provided with an inlet chamber and a plurality of outlet chambers.

[0009] Furthermore, the opposing liquid suction assembly includes a centrifugal pump and a main suction pipe. The centrifugal pump is installed on the top surface of the biogas slurry drip irrigation treatment tank, and the main suction pipe is installed on the outer surface of the output end of the centrifugal pump. A three-way flange is installed on the outer surface of the main suction pipe.

[0010] Furthermore, a secondary suction pipe is installed on one end surface of the tee flange, and a secondary suction pipe is installed on the other end surface of the tee flange. A shut-off valve is installed inside the secondary suction pipe.

[0011] Furthermore, a shut-off valve 2 is installed inside the secondary suction pipe 2, one end surface of the secondary suction pipe 1 extends into the left suction chamber, and one end surface of the secondary suction pipe 2 extends into the right suction chamber.

[0012] Furthermore, the floating assembly includes two limiting posts and two retaining rings. The two limiting posts are installed inside the biogas slurry drip irrigation treatment tank, and retaining rings are installed on the top surface of each of the two limiting posts.

[0013] Furthermore, each of the outer surfaces of the limiting post is movably mounted with a floating plate, and the bottom surfaces of the two floating plates are jointly mounted with a connecting base, the top surface of the connecting base being fixedly connected to the bottom surface of the protective sleeve.

[0014] Beneficial effects The present invention has the following beneficial effects: (1) The continuous biogas slurry drip irrigation fertilization device changes the flow direction of biogas slurry by making the left and right suction chambers work alternately, thereby causing the attached materials on the screen plate to fall off automatically. When the left suction chamber is working, biogas slurry flows unidirectionally from the sedimentation chamber and the right suction chamber through the screen plate 1 and screen plate 2 of the left suction chamber. A stable attachment layer is formed on the outside of the screen plate 1. When the state is switched, when the right suction chamber is working, the left suction chamber stops absorbing liquid, and the biogas slurry in the sedimentation chamber is diverted to the right suction chamber. The flow channel from the sedimentation chamber to the right suction chamber forms a new flow direction, resulting in a pressure difference on both sides of the screen plate 1. The pressure on the sedimentation chamber side increases briefly due to the change in the flow channel, and the flow velocity is concentrated in the right suction chamber. The pressure on the left suction chamber side is close to static due to no liquid absorption and is only affected by the gravity of the residual biogas slurry. Large impurities fall off because the adhesion force is less than the shear force generated by the pressure difference, thereby automatically cleaning the attached debris on the outside of the screen plate 1, so that the biogas slurry drip irrigation can be carried out stably and continuously.

[0015] (2) This continuous biogas slurry drip irrigation fertilization device, by placing the protective sleeve at a certain distance below the surface of the biogas slurry, and by stably driving the telescopic water pipe to extend and retract when the protective sleeve descends, the biogas slurry will form obvious vertical stratification in a slow flow state. The surface layer is a high-concentration scum layer, the middle layer is a clear liquid layer with low impurities and high nutrients, and the bottom layer is a sediment layer. The protective sleeve is at a certain distance below the liquid surface, which can accurately draw the middle clear liquid. This layer has a high content of dissolved nutrients and avoids the intake of large particles and long fibers in the scum, as well as sand and heavy metal precipitates in the sediment layer. This can reduce the loss of nutrients during the transmission process and improve the nutrient utilization rate. In addition, large particles and long fibers in the surface scum can easily clog the drippers, causing the drip irrigation main pipe to malfunction. The protective sleeve avoids the scum layer, which can significantly reduce the dripper clogging rate. The sand and heavy metal precipitates in the bottom sediment can wear down the pump impeller, which can shorten the pump life. The protective sleeve avoids the sediment layer, which can reduce pump wear and extend the pump life.

[0016] (3) The continuous biogas slurry drip irrigation fertilization device uses several scrapers to clean several mesh holes 2, and several scrapers 2 to clean several mesh holes 1, so that no debris is attached to the outside of the protective sleeve. Several mesh holes 2 and several mesh holes 1 provide double protection to prevent debris from entering the drip irrigation main pipe. The scraper 1 and mesh holes 2, and the scraper 2 and mesh holes 1 work together to clean. With the graded interception of the double mesh holes 1 and 2, the debris on the outside of the protective sleeve can be efficiently removed and impurities of different particle sizes can be completely blocked from entering the drip irrigation main pipe, ensuring the long-term stable operation of the drip irrigation system.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] Please see Figures 1-7 This invention provides a technical solution: a continuous biogas slurry drip irrigation fertilization device, including a biogas slurry drip irrigation treatment tank 1, a left suction chamber 101 and a right suction chamber 102 are provided inside the biogas slurry drip irrigation treatment tank 1, a sedimentation chamber 103 is provided inside the biogas slurry drip irrigation treatment tank 1, and two partitions 104 are installed inside the biogas slurry drip irrigation treatment tank 1. A mesh plate 105 and a mesh plate 106 are installed on the inner walls of both partitions 104. The biogas slurry drip irrigation treatment tank 1 includes a counter-current pumping assembly 2, two floating assemblies 3, two anti-clogging assemblies 4, and two accelerating assemblies 5. The anti-clogging assembly 4 includes a telescopic water pipe 401 and a protective sleeve 402. The telescopic water pipe 401 is installed on the outer surface of the counter-current pumping assembly 2, and the protective sleeve 402 is installed on the outer surface of the telescopic water pipe 401. The protective sleeve 402 has a cavity 405 inside, and a number of mesh holes 403 are evenly distributed on the outer surface of the protective sleeve 402. A number of mesh holes 404 are evenly distributed on the inner surface of the protective sleeve 402. The opposing suction components 2 alternately suction the biogas slurry from the left suction chamber 101 and the right suction chamber 102. The alternating operation of the left and right suction chambers 101 and 102 creates a periodic flow of biogas slurry, keeping impurities suspended in the flow. When the right suction chamber 102 is suctioning, the left suction chamber 101 flows in the opposite direction, creating a push-pull effect that prevents impurities from adhering to the screen plate 105. The floating component 3 adjusts the height of the protective sleeve 402 according to the liquid level in the biogas slurry drip irrigation tank 1, placing the protective sleeve 402 below the liquid surface. This avoids high-concentration scum and sediment, allowing direct suction of the clear liquid with low impurities and high nutrients. The accelerating component 5 accelerates the flow of biogas slurry, providing power to the anti-clogging component 4. The anti-clogging component 4 prevents the protective sleeve 402 from clogging, causing the left and right suction chambers 101 and 102 to work alternately, thus changing the flow direction of the biogas slurry and allowing the screen plate 105 to... The attached material on 105 automatically falls off. When the left suction chamber 101 is working, the biogas slurry flows unidirectionally from the sedimentation chamber 103 and the right suction chamber 102 through the mesh plate 105 and mesh plate 106 of the left suction chamber 101. A stable attachment layer is formed on the outside of the mesh plate 105. When switching states, when the right suction chamber 102 is working, the left suction chamber 101 stops suctioning. The biogas slurry in the sedimentation chamber 103 is diverted to the right suction chamber 102. A new flow direction is formed in the flow channel from the sedimentation chamber 103 to the right suction chamber 102, resulting in a pressure difference on both sides of the mesh plate 105. The pressure on the sedimentation chamber 103 side increases briefly due to the change in the flow channel, and the flow velocity is concentrated in the right suction chamber 102. The pressure on the left suction chamber 101 side is close to static due to no suction, and is only affected by the gravity of the residual biogas slurry. Large impurities fall off because the adhesion force is less than the shear force generated by the pressure difference, thereby automatically cleaning the attached debris on the outside of the mesh plate 105.

[0023] The anti-blocking component 4 also includes a limiting ring groove 406 and a limiting slip ring 407. The limiting ring groove 406 is formed inside the protective sleeve 402. The limiting slip ring 407 is movably installed on the inner wall of the limiting ring groove 406. Several scraper blades 408 are evenly distributed on the bottom surface of the limiting slip ring 407, and several scraper blades 409 are evenly distributed on the bottom surface of the limiting slip ring 407. The outer surfaces of the scraper blades 408 are in contact with the inner wall of the cavity 405, and the outer surfaces of the scraper blades 409 are in contact with the outer surface of the protective sleeve 402. Several connecting posts 410 are evenly distributed on the top surface of the limiting slip ring 407, and ball bearings 411 are installed on the top surface of each connecting post 410, so that the limiting slip ring 407... 07 drives several scraper blades 408 and 409 to rotate. The scraper blades 408 clean the mesh openings 404, and the scraper blades 409 clean the mesh openings 403, thus preventing debris from adhering to the outside of the protective sleeve 402. The mesh openings 404 and 403 provide double protection to prevent debris from entering the drip irrigation main pipe 207. The scraper blades 408 and 404, and the scraper blades 409 and 403 work together to clean, and with the graded interception of the double mesh openings 403 and 404, debris on the outside of the protective sleeve 402 can be efficiently removed and impurities of different particle sizes can be completely blocked from entering the drip irrigation main pipe 207, ensuring the long-term stable operation of the drip irrigation system.

[0024] The acceleration assembly 5 includes an acceleration liquid shell plate 501 and an inlet chamber 502. The acceleration liquid shell plate 501 is installed on the outer surface of the partition plate 104. The acceleration liquid shell plate 501 is provided with an inlet chamber 502 and a plurality of outlet chambers 503. The biogas slurry flows out through the inlet chamber 502 of the acceleration liquid shell plate 501 and then out through the plurality of outlet chambers 503. The inlet area of ​​the inlet chamber 502 is larger than the outlet area of ​​the outlet chamber 503, thereby accelerating the biogas slurry to flow out of the outlet chamber 503. The accelerated biogas slurry flow rate pushes the ball baffle shaft 411.

[0025] The opposing suction assembly 2 includes a centrifugal pump 201 and a main suction pipe 202. The centrifugal pump 201 is installed on the top surface of the biogas slurry drip irrigation treatment tank 1. The main suction pipe 202 is installed on the outer surface of the output end of the centrifugal pump 201. A three-way flange 208 is installed on the outer surface of the main suction pipe 202. A secondary suction pipe 203 is installed on one end of the three-way flange 208, and a secondary suction pipe 204 is installed on the other end of the three-way flange 208. A stop valve 205 is installed inside the secondary suction pipe 203, and a stop valve 206 is installed inside the secondary suction pipe 204. One end surface extends into the left suction chamber 101, and one end surface of the auxiliary suction pipe 204 extends into the right suction chamber 102. The controller closes the shut-off valve 206 of the auxiliary suction pipe 204 and the shut-off valve 205 of the auxiliary suction pipe 203. The controller then controls the centrifugal pump 201 to work, so that the biogas slurry in the left suction chamber 101 is sucked into the telescopic water pipe 401 through the mesh 403 and mesh 404 of the protective sleeve 402. The telescopic water pipe 401 is made of TPE thermoplastic elastomer material, so that it can extend and retract stably.

[0026] The floating component 3 includes two limiting posts 301 and two retaining rings 302. The two limiting posts 301 are installed inside the biogas slurry drip irrigation treatment tank 1. Each limiting post 301 has a retaining ring 302 installed on its top surface. Each limiting post 301 has a float plate 303 movably installed on its outer surface. The bottom surfaces of the two float plates 303 are connected to a connecting base 304. The top surface of the connecting base 304 is fixedly connected to the bottom surface of the protective sleeve 402. By stably driving the telescopic water pipe 401 to extend and retract, the biogas slurry will form obvious vertical stratification in a slow-flowing state. The surface layer is a high-concentration scum layer, the middle layer is a clear liquid layer with low impurities and high nutrients, and the bottom layer is sediment. The protective sleeve 402 is positioned a certain distance below the liquid surface, allowing for precise absorption of the middle layer of clarified liquid. This layer has a high content of dissolved nutrients and avoids the intake of large particles and long fibers from the scum, as well as sand and heavy metal precipitates from the sediment layer. This reduces nutrient loss during transmission and improves nutrient utilization. Furthermore, large particles and long fibers in the surface scum can easily clog the drippers, causing the drip irrigation main 207 to malfunction. The protective sleeve 402 avoids the scum layer, significantly reducing the dripper clogging rate. Sand and heavy metal precipitates in the bottom sediment layer can wear down the pump impeller, shortening the pump's lifespan. The protective sleeve 402 avoids the sediment layer, reducing pump wear and extending the pump's lifespan.

[0027] The specific workflow of this invention is as follows: When drip irrigation fertilization of farmland using biogas slurry products is required, a large amount of biogas slurry from the biogas slurry pond is drawn into the sedimentation chamber 103 of the biogas slurry drip irrigation treatment tank 1. As the large amount of biogas slurry enters the tank 1, it passes through the mesh plates 105 and 106 at both ends, thus allowing the biogas slurry to enter the left suction chamber 101 and the right suction chamber 102. The controller closes the shut-off valve 206 of the auxiliary suction pipe 204 and the shut-off valve 205 of the auxiliary suction pipe 203. Then, the controller controls the centrifugal pump 201 to operate. 201 operates, allowing the biogas slurry in the left suction chamber 101 to be drawn into the telescopic water pipe 401 through the mesh openings 403 and 404 of the protective sleeve 402. The telescopic water pipe 401 is made of TPE thermoplastic elastomer material, ensuring stable extension and contraction. While the left suction chamber 101 is absorbing biogas slurry, the biogas slurry in the middle sedimentation chamber 103 enters the left suction chamber 101 through the mesh plates 105 and 106. Impurities in the biogas slurry in the middle sedimentation chamber 103 are adsorbed on the outside of the mesh plate 105, and the mesh plate 106 provides an additional layer of protection. After the left suction chamber 101 has been absorbing biogas slurry for a certain period of time... The controller opens the shut-off valve 206 of the secondary suction pipe 204 and the shut-off valve 205 of the secondary suction pipe 103, thereby allowing the right suction chamber 102 to suction biogas slurry. This causes the left and right suction chambers 101 to operate intermittently, changing the flow direction of the biogas slurry and causing the deposits on the mesh plate 105 to automatically detach. When the left suction chamber 101 is working, biogas slurry flows unidirectionally from the sedimentation chamber 103 and the right suction chamber 102 through the mesh plate 105 and mesh plate 106 of the left suction chamber 101, forming a stable deposit layer on the outside of the mesh plate 105. When switching states, when the right suction chamber 102 is working, the left suction chamber 101 stops suctioning. The biogas slurry in the sedimentation chamber 103 is diverted to the right suction chamber 102, and a new flow direction is formed in the flow channel from the sedimentation chamber 103 to the right suction chamber 102. This causes a pressure difference to be generated on both sides of the screen plate 105. The pressure on the sedimentation chamber 103 side increases briefly due to the change in the flow channel, and the flow velocity is concentrated in the right suction chamber 102. The pressure on the left suction chamber 101 side is close to static due to the lack of suction, and is only affected by the gravity of the residual biogas slurry. Large impurities fall off because the adhesion force is less than the shear force generated by the pressure difference, thereby automatically cleaning the attached debris on the outside of the screen plate 105.

[0028] Furthermore, when the biogas slurry level in the drip irrigation treatment tank 1 drops, the two floats 303 drive the connecting base 304 and the protective sleeve 402 to descend synchronously. The two floats 303 descend slowly on the outer surface of the limiting post 301, and the retaining ring 302 places the floats 303 outside the limiting post 301. The connecting base 304 positions the protective sleeve 402 a certain distance below the biogas slurry level. As the protective sleeve 402 descends, it stabilizes and drives the telescopic water pipe 401 to extend and retract. Under slow flow, the biogas slurry forms obvious vertical stratification: a high-concentration scum layer on the surface, a clear liquid layer with low impurities and high nutrients in the middle, and a sediment layer at the bottom. The protective sleeve 402 is positioned at a certain distance below the liquid surface, allowing for precise absorption of the middle layer of clarified liquid. This layer has a high content of dissolved nutrients and avoids the intake of large particles and long fibers from the scum, as well as sand and heavy metal precipitates from the sediment layer. This reduces nutrient loss during transmission and improves nutrient utilization. Furthermore, large particles and long fibers in the surface scum can easily clog the drippers, causing the drip irrigation main 207 to malfunction. The protective sleeve 402 avoids the scum layer, significantly reducing the dripper clogging rate. Sand and heavy metal precipitates in the bottom sediment layer can wear down the pump impeller, shortening the pump's lifespan. The protective sleeve 402 avoids the sediment layer, reducing pump wear and extending the pump's lifespan.

[0029] Furthermore, when the biogas slurry drip irrigation treatment tank 1 is treating and absorbing the biogas slurry, the biogas slurry flows through the inlet chamber 502 of the accelerating liquid shell plate 501, and then flows out from several outlet chambers 503. The inlet area of ​​the inlet chamber 502 is larger than the outlet area of ​​the outlet chamber 503, thereby accelerating the flow of biogas slurry out of the outlet chambers 503. This accelerated biogas slurry flow velocity pushes the ball baffle shaft 411. The ball baffle shaft 411 drives the limiting slip ring 407 to rotate within the limiting ring groove 406 through the connecting column 410. This causes the limiting slip ring 407 to drive several scraper blades 408 and several scraper blades 409 to rotate. The scraper blades 408 then rotate on several scraper blades 409. The protective sleeve 402 is cleaned by several mesh openings 404 and several scrapers 409 clean several mesh openings 403, thus preventing debris from adhering to the outside of the protective sleeve 402. The several mesh openings 404 and several mesh openings 403 provide double protection to prevent debris from entering the drip irrigation main pipe 207. The scrapers 408 and mesh openings 404, and scrapers 409 and mesh openings 403 work together to clean. With the graded interception of the double mesh openings 403 and 404, debris on the outside of the protective sleeve 402 can be efficiently removed and impurities of different particle sizes can be completely blocked from entering the drip irrigation main pipe 207, ensuring the long-term stable operation of the drip irrigation system.
