Description

Technical Field

[0001] This invention belongs to the field of biogas engineering technology, and specifically relates to an organic fertilizer composting and fermentation device for residual biogas residue in biogas projects. Background Technology

[0002] Biogas engineering is an environmentally friendly energy project that utilizes organic waste to produce biogas through microbial metabolism in a closed anaerobic environment, thereby realizing energy recovery and solid waste resource utilization. Its core processes include raw material pretreatment, anaerobic fermentation, biogas purification, biogas storage and utilization, and by-product treatment. The project has triple benefits of energy production, pollution control, and resource recycling. It can effectively solve the problem of organic waste pollution, reduce greenhouse gas emissions, and produce clean energy and organic fertilizer. It can be widely used in large-scale livestock and poultry breeding, agricultural waste treatment, industrial organic wastewater treatment and other fields. It is an important technical carrier for promoting ecological circular agriculture and energy conservation and emission reduction. In organic fertilizer composting and fermentation devices used for biogas residue, there is usually a core component called a perforated pipe, which is used to introduce external oxygen into the biogas residue. However, the fine particles of biogas residue and the mucus produced by microbial metabolism form a "mud film" on the outer surface of the orifice, which gradually blocks the orifice, causing a sharp drop in airflow, or even no airflow in some areas. Therefore, it is necessary to remove impurities from the surface of the perforated pipe and prevent blockage. Summary of the Invention

[0003] The purpose of this invention is to provide an organic fertilizer composting and fermentation device for residual biogas residue in biogas projects, which has the advantage of removing impurities adhering to the surface of perforated pipes and preventing blockage.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an organic fertilizer composting and fermentation device for residual biogas residue in biogas projects, comprising a cylinder, a servo motor welded to the upper end of the cylinder, an agitator fixedly connected to the output end of the servo motor via a coupling, the agitator being disposed inside the cylinder, a feed inlet welded to one side of the upper end of the cylinder, a vent welded to one side of the upper end of the cylinder, three sets of support legs welded to the lower end of the cylinder, a strip-shaped hole opened at the bottom of the cylinder, a striking component disposed together with the bottom of the cylinder and the strip-shaped hole, a cleaning component disposed inside the striking component, an observation plate disposed on one side of the cylinder, and a discharge port welded to the lower end of one side of the cylinder.

[0005] Using the above technical solution, during use, the material is poured into the inside of the cylinder from the feed inlet, and then the servo motor is run. The servo motor drives the stirring paddle to rotate, which stirs and mixes the material inside the cylinder. The components inside the striking assembly supply oxygen to the inside of the cylinder while preventing the material inside the cylinder from clogging the oxygen supply structure. When the striking assembly supplies oxygen to the inside of the cylinder, it will bring some external dust into the oxygen supply structure, and some material in the cylinder may also fall into the oxygen supply structure from the vent on the surface of the oxygen supply structure. Therefore, the cleaning assembly can scrape off the residue and dust inside the oxygen supply structure, and the vent is used to ventilate the inside of the cylinder.

[0006] The present invention is further configured such that: the striking assembly includes a fixing plate, the fixing plate is welded to one side of the cylinder, a shell is bolted inside the fixing plate, a fan is rotatably connected inside the shell, a dual-axis motor is bolted to one side of the fan and the dual-axis motor is bolted to the surface of the shell, a pinion is bolted to the other output end of the dual-axis motor, an air supply pipe is fixedly connected to one side of the fan, and a one-way valve is installed on the air supply pipe.

[0007] Using the above technical solution, when in use, the fan will run and introduce external oxygen into the perforated pipe from the gas supply pipe, and finally discharge it into the material inside the cylinder from the through hole.

[0008] The invention is further configured such that: a large gear is meshed with the surface of the small gear; a central column is rotatably connected to the middle of the large gear; a connecting block is welded to the surface of the central column and the connecting block is welded to the surface of the cylinder; four first positioning holes are opened on the surface of the large gear; a stud is threadedly connected inside one of the first positioning holes; a push-pull plate is rotatably connected to the surface of the stud; a connecting rod is rotatably connected to the other end of the push-pull plate, and the connecting rod is slidably connected to the strip hole.

[0009] Using the above technical solution, when the through hole of the perforated tube is slightly blocked, the stud can be passed through the push-pull plate and rotatably connected to the innermost first positioning hole on the surface of the large gear.

[0010] The invention is further configured such that: a sliding plate is welded to the surface of the connecting rod, and the sliding plate is slidably connected to the lower surface of the strip hole; limit plates are slidably connected to both sides inside the sliding plate, and the limit plates are welded to the surface of the cylinder; a perforated pipe is welded to one end of the connecting rod, and the perforated pipe is fixedly connected to the gas supply pipe; several sets of through holes are opened on the surface of the perforated pipe; an installation block is welded to the lower end of the perforated pipe; a slide rail is slidably connected to the surface of the installation block, and the slide rail is welded to the bottom of the cylinder.

[0011] Using the above technical solution, the dual-axis motor drives the pinion to rotate during operation. The rotation of the pinion drives the large gear to rotate on the surface of the central column. Due to the transmission ratio setting of the pinion and the large gear, when the pinion rotates five times, it will drive the large gear to rotate one time. This will cause the stud to continuously push and pull the push-pull plate back and forth. At the same time, the other end of the push-pull plate rotates on the surface of the connecting rod, causing the connecting rod to drive the slide plate to slide on the surface of the limiting plate. The slide plate is used to block and seal the strip hole. As the connecting rod continues to reciprocate, it will drive the perforated tube to continuously reciprocate inside the limiting tube.

[0012] The present invention is further configured such that: both ends of the perforated tube are slidably connected to limit tubes, and the limit tubes are welded to both sides inside the cylinder; the limit tubes are threadedly connected to screw blocks; a rotating rod is welded to one side of the screw block; a first arc-shaped shell is bolted to the other side of the screw block; and three sets of scales are welded to the surface of the limit tubes.

[0013] Using the above technical solution, rotating the rotating rod causes the screw block to rotate inside the limiting tube, which in turn moves the first arc-shaped shell forward to the first mark closest to the rubber pad.

[0014] The present invention is further configured such that: the cleaning component includes a rotating shaft, and four sets of rotating shafts are provided, the four sets of rotating shafts are respectively provided at both ends of the perforated tube, a rotating ring is fixedly connected between two sets of rotating shafts, a lead screw is bolted between two sets of rotating rings, and a threaded plate is threadedly connected to the surface of the lead screw.

[0015] Using the above technical solution, the rotating ring is rotated by the rotating shaft. When the rotating ring rotates, it will drive the lead screw to move synchronously. In this way, the lead screw will drive the threaded plate to move inside the perforated tube and push the residue inside the perforated tube to one end. The limiting rod is used to limit the movement of the threaded plate and prevent the threaded plate from rotating with the rotation of the lead screw.

[0016] The invention is further configured such that: top rods are welded to both sides of the threaded plate, a limiting rod is slidably connected inside the threaded plate and the limiting rod is welded to the inner wall of the perforated tube, and a material discharge hole is opened on both sides of the perforated tube, wherein three sets of fixing rods are fixedly connected to one side of each of the two sets of rotating shafts.

[0017] Using the above technical solution, when the threaded plate pushes the residue inside the perforated tube to the position of the discharge hole, the residue will fall off from the position of the discharge hole, thereby completing the cleaning of the residue inside the perforated tube.

[0018] The invention is further configured such that: a connecting plate is welded to one end of each of the three sets of fixing rods, a bent plate is welded to one side of the connecting plate, a positioning rod is slidably connected inside the bent plate, a tension spring is sleeved on the surface of the positioning rod, and both ends of the tension spring are connected between the positioning rod and the bent plate through spring fixing members.

[0019] Using the above technical solution, since the upper middle part of one side of the connecting plate contains a bent plate, a positioning rod, and a tension spring, the weight of the upper middle part of the connecting plate is greater than the weight of the lower middle part. Therefore, the connecting plate will rotate using a pivot, so that the positioning rod always remains in the position with the larger end facing down.

[0020] The present invention is further configured such that: a second arc-shaped shell is welded to one side of the connecting plate, a top plate is detachably connected to the middle of the surface of the second arc-shaped shell, a sliding column is welded to one side of the top plate, and the sliding column and the second arc-shaped shell are slidably connected, a second positioning hole is opened on the surface of the sliding column, and the second positioning hole and the positioning rod are detachably connected.

[0021] By adopting the above technical solution, when the sliding column moves forward to a certain position, the tension spring will pull the positioning rod to be positioned inside the second positioning hole. This will keep the top plate in a state of pushing the rubber pad outward, thereby improving the service life and utilization rate of the rubber pad.

[0022] The invention is further configured such that: a rubber pad is adhered to one side of the second arc-shaped shell, and three sets of ball bearings are rotatably connected inside the rubber pad.

[0023] By adopting the above technical solution, when the rubber pad impacts the first arc-shaped shell, the ball will roll on the surface of the first arc-shaped shell, which will change the sliding friction between the rubber pad and the first arc-shaped shell into rolling friction, thereby reducing the wear of the rubber pad.

[0024] In summary, the present invention has the following beneficial effects: 1. Through the design of perforated tube, limiting tube, rubber pad and threaded plate, the material can be prevented from clogging the through hole on the surface of the perforated tube by vibrating the perforated tube. 2. The design of the threaded plate can push out the residue inside the perforated tube, thereby ensuring air circulation inside the perforated tube; 3. The top plate design allows for the restoration of dented or deformed rubber pads, thereby improving the service life and utilization rate of the rubber pads. Attached Figure Description

The components inside the striking component 7 supply oxygen to the cylinder 1 while preventing the material inside the cylinder 1 from clogging the oxygen supply structure. When the striking component 7 supplies oxygen to the cylinder 1, it will bring some external dust into the oxygen supply structure. Material in the cylinder 1 may also fall into the oxygen supply structure from the exhaust port on the surface of the oxygen supply structure. Therefore, the cleaning component 10 can scrape off the residue and dust inside the oxygen supply structure. The vent 4 is used to ventilate the inside of the cylinder 1.

[0030] Example 2: Based on Example 1, and referring to Figures 3-12The striking assembly 7 includes a fixing plate 701, which is welded to one side of the cylinder 1. A housing 725 is bolted inside the fixing plate 701. A fan 707 is rotatably connected inside the housing 725. A dual-axis motor 724 is bolted to one side of the fan 707 and bolted to the surface of the housing 725. A pinion 721 is bolted to the other output end of the dual-axis motor 724. An air supply pipe 708 is fixedly connected to one side of the fan 707, and a one-way valve 12 is installed on the air supply pipe 708. There is an air supply pipe 708, and a one-way valve 12 is installed on the air supply pipe 708; a large gear 703 is meshed with the surface of a small gear 721, and a central column 722 is rotatably connected to the middle of the large gear 703. A connecting block 723 is welded to the surface of the central column 722 and is welded to the surface of the cylinder 1. Four first positioning holes 702 are opened on the surface of the large gear 703. A stud 704 is threadedly connected to the inside of one of the first positioning holes 702.

A slide rail 720 is slidably connected to the surface of the mounting block 719, and the slide rail 720 is welded to the bottom of the inner cylinder 1. Limiting tubes 713 are slidably connected to both ends of the perforated tube 712, and the limiting tubes 713 are welded to both sides inside the cylinder 1. A screw block 716 is threaded inside the limiting tube 713. A rotating rod 717 is welded to one side of the screw block 716, and a first arc-shaped shell 715 is bolted to the other side of the screw block 716. Three sets of scales 714 are welded to the surface of the limiting tube 713.

[0031] The cleaning component 10 includes a rotating shaft 1001, and four sets of rotating shafts 1001 are provided. The four sets of rotating shafts 1001 are respectively located at both ends of the perforated tube 712. A rotating ring 1002 is fixedly connected between two sets of rotating shafts 1001. A threaded rod 1018 is bolted between two sets of rotating rings 1002. A threaded plate 1015 is threaded onto the surface of the threaded rod 1018. A push rod 1016 is welded to both sides of the threaded plate 1015. A limit rod 1014 is slidably connected inside the threaded plate 1015 and is welded to the inner wall of the perforated tube 712. A material discharge hole 1017 is opened on both sides of the perforated tube 712. Three sets of fixing rods 1004 are fixedly connected to one side of each set of rotating shafts 1001. A connecting plate 1003 is welded to one end of each of the three sets of fixing rods 1004.

A rubber pad 1007 is adhered to one side of the second arc-shaped shell 1006, and three sets of ball bearings 1008 are rotatably connected inside the rubber pad 1007.

[0032] Brief description of usage: During use, fan 707 is driven by dual-axis motor 724, and fan 707 draws external air into perforated pipe 712 through air supply pipe 708, and finally discharges it into the material inside cylinder 1 through through hole 718. The air bubbles on the surface of the material inside cylinder 1 can then be observed through observation plate 5. When through hole 718 of perforated pipe 712 is slightly blocked, the bubbles on the surface are evenly distributed in the material layer and are of moderate size. Moderate blockage results in uneven bubble distribution, with fewer bubbles in some areas and larger bubbles in others. Severe blockage results in almost no bubbles, or only a few large bubbles slowly rising from the bottom edge. The condition of the bubbles indicates the blockage of perforated pipe 712. 2. Blockage will affect the oxygen supply to the material inside cylinder 1. Therefore, when the through hole 718 of the perforated pipe 712 is slightly blocked, the stud 704 can be passed through the push-pull plate 705 and rotatably connected to the innermost first positioning hole 702 on the surface of the large gear 703. Rotating the rotating rod 717 will cause the screw block 716 to rotate inside the limiting tube 713, which will move the first arc-shaped shell 715 forward to the first mark 714 closest to the rubber pad 1007. (When moderate blockage occurs, the stud 704 needs to be inserted into the second first positioning hole 702 from the inside on the surface of the large gear 703, thus moving the first arc-shaped shell 715 to the middle mark 714. The same applies to severe blockage.) (And so on). During operation, the dual-axis motor 724 drives the pinion 721 to rotate. The rotation of the pinion 721 drives the large gear 703 to rotate on the surface of the central column 722. Due to the transmission ratio between the pinion 721 and the large gear 703, when the pinion 721 rotates five times, it drives the large gear 703 to rotate one time. This causes the stud 704 to continuously push and pull the push-pull plate 705. Simultaneously, as the other end of the push-pull plate 705 rotates on the surface of the connecting rod 709, the connecting rod 709 drives the sliding plate 710 to slide on the surface of the limiting plate 711. The sliding plate 710 is used to block and seal the strip hole 11. With the continuous reciprocating motion of the connecting rod 709, the perforated tube 712 is driven to utilize the mounting block 7... The sliding characteristic of mounting block 719 within slide rail 720 causes perforated tube 712 to reciprocate continuously within limiting tube 713. (A TiN / TiCN hard coating is applied to the contact area between mounting block 719 and slide rail 720, which greatly reduces the wear of the contact surface by particles when mounting block 719 slides on the surface of slide rail 720. The ultra-smooth properties of the coating also help to remove particles that have entered between mounting block 719 and slide rail 720 during the movement of mounting block 719 on the surface of slide rail 720.) Furthermore, perforated tube 712 causes rubber pad 1007 to continuously impact the first arc-shaped shell 715. The vibration generated by the impact, combined with the air blown out by fan 707, is discharged through the through hole 718 on the surface of perforated tube 712.This causes the material adhering to the surfaces of the perforated tube 712 and the through hole 718 to detach. During the impact of the rubber pad 1007 with the first arc-shaped shell 715, the ball bearing 1008 rolls on the surface of the first arc-shaped shell 715. This transforms the sliding friction between the rubber pad 1007 and the first arc-shaped shell 715 into rolling friction, thereby reducing the wear on the rubber pad 1007. [The ball bearing 1008 is embedded inside the rubber pad 1007, and the rubber pad 1007 is made of soft EPDM rubber (Shore).] (Shore A 35-45 degrees), the inner wall of the groove on the surface of the rubber pad 1007 where the ball bearings 1008 are embedded needs to be coated with a thin layer of PTFE (polytetrafluoroethylene) coating. This improves smoothness and enhances the anti-stick effect. Furthermore, the opening edge of the groove where the ball bearings 1008 are embedded is sprayed with a 1-1.5mm wide wear-resistant rubber coating and hardened to a Shore A hardness of 60-70 degrees. The hardened edge prevents the groove opening from widening when the rubber pad 1007 is impacted and deformed, thus preventing the ball bearings 1008 from slipping out of the edge.

[0033] It should be noted that the slide rail 720 is made of duplex stainless steel, which can improve the corrosion resistance of the slide rail 720 and thus improve its service life. In addition, sealing gaskets are provided between the perforated tube 712 and the limiting tube 713, and between the slide plate 710 and the cylinder 1 to prevent material leakage.

[0034] When the material inside the cylinder 1 is emptied from the outlet 6, some dust from the outside will be introduced into the perforated tube 712 during the operation of the fan 707, and occasionally some residue from the material inside the cylinder 1 will enter the perforated tube 712 through the through hole 718 (the one-way valve 12 is used to prevent the residue entering the perforated tube 712 from entering the air supply pipe 708 and the fan 707, which would damage the fan 707). Therefore, the screw block 716 can be removed from the limiting tube 713, and then the stud 704 is rotated through the push-pull plate 705 and connected to the first positioning hole 702 on the outermost surface of the large gear 703. In this way, the operation of the dual-shaft motor 724 will drive the large gear 703 to rotate, and the large gear 703 will use the push-pull plate 705 to push the perforated tube 712 through the limiting tube 713. 3. The perforated tube 712 is removed from the inside of the limiting tube 713. After removal, the operation of the fan 707 is stopped, keeping the perforated tube 712 outside the limiting tube 713. Then, the rotating ring 1002 can be rotated using the rotating shaft 1001. When the rotating ring 1002 rotates, it will drive the lead screw 1018 to move synchronously. In this way, the lead screw 1018 will drive the threaded plate 1015 to move inside the perforated tube 712 and push the residue inside the perforated tube 712 to one end. The limiting rod 1014 is used to limit the movement of the threaded plate 1015 to prevent the threaded plate 1015 from rotating with the rotation of the lead screw 1018. When the threaded plate 1015 pushes the residue inside the perforated tube 712 to the position of the discharge hole 1017, the residue will fall off from the position of the discharge hole 1017, thus completing the cleaning of the residue inside the perforated tube 712.

[0035] It should be noted that the surface of the lead screw 1018 is coated with polytetrafluoroethylene (PTFE) to make it smooth, which reduces the adhesion of sticky impurities in the biogas sludge. Furthermore, because the diameter of the through-hole 718 is 0.5-1mm and it is angled downwards at 35°, the airflow sweeps along the pipe wall towards the bottom of the tank during aeration, greatly reducing the probability of sludge / material falling into the through-hole 718 due to gravity after shutdown. Also, because the through-hole 718 is angled downwards at 35°, its position is lower than that of the lead screw 101. The height is 8, so even if a very small amount of material enters the perforated tube 712 through the through hole 718, it will not affect the lead screw 1018. Because of the polytetrafluoroethylene coating and the fact that the perforated tube 712 uses the rubber pad 1007 to continuously impact the first arc-shaped shell 715 to generate vibration, even if a small amount of material splashes onto the surface of the lead screw 1018, the vibration will cause the material on the surface of the lead screw 1018 to fall off quickly. Therefore, the material falling onto the surface of the lead screw 1018 will not affect the use of the lead screw 1018.

[0036] When the rubber pad 1007 impacts the first arc-shaped shell 715 for an extended period, one end of the rubber pad 1007 will deform and become dented. Therefore, to address the issue and improve the utilization rate of the rubber pad 1007, the rotating ring 1002 can be rotated. This causes the rotating ring 1002 to rotate the lead screw 1018, which in turn moves the threaded plate 1015 and the push rod 1016. Since the upper middle part of one side of the connecting plate 1003 contains the bent plate 1010, the positioning rod 1011, and the tension spring 1012, the weight of the upper middle part of the connecting plate 1003 is greater than that of the lower middle part. This causes the connecting plate 1003 to rotate using the rotating shaft 1001, ensuring that the positioning rod 1011 always remains in the position with its larger end facing down. Figure 9 The positioning rod 1011 is positioned with the larger end facing upwards. Therefore, as the threaded plate 1015 moves forward, it will drive the push rod 1016 to push one end of the sliding column 1005. This causes the sliding column 1005 to slide inside the connecting plate 1003, while simultaneously driving the top plate 1013 to move forward. This will push open the recessed part at one end of the rubber pad 1007. When the sliding column 1005 moves forward to a certain position, the tension spring 1012 will pull the positioning rod 1011 to be positioned inside the second positioning hole 1009. This will keep the top plate 1013 in a state of pushing the rubber pad 1007 outwards, thereby improving the service life and utilization rate of the rubber pad 1007.
