Description

Technical Field

[0001] This invention relates to the field of agricultural organic solid waste treatment equipment technology, specifically to an organic solid waste treatment device. Background Technology

[0002] Agricultural organic solid waste mainly refers to waste containing large amounts of organic matter generated during agricultural production, such as crop straw, discarded vegetables, and fruit vines. With the increasing intensification of agriculture in my country, the amount of agricultural organic solid waste generated is increasing year by year, making its treatment and disposal an important issue in rural environmental governance. Currently, common treatment methods for agricultural organic solid waste mainly include direct return to the field, anaerobic fermentation to produce biogas, and incineration for power generation. Among these, incineration is widely used in large-scale treatment scenarios due to its high volume reduction rate, fast processing speed, and ability to recover heat energy.

[0003] However, during the collection and transportation of existing agricultural organic solid waste, agricultural plastic film widely used in agricultural production is often mixed in. This residual film poses a serious challenge to subsequent treatment processes after entering the treatment system. Specifically, if organic solid waste mixed with agricultural film residue is directly incinerated, the plastic components, under incomplete combustion conditions, readily react with chlorine sources in the waste, generating large amounts of dioxins and other toxic substances. To completely decompose dioxins and achieve harmless emissions, according to relevant environmental regulations, the flue gas temperature in the incinerator must reach above 850 degrees Celsius and maintain a sufficient residence time. However, for ordinary agricultural businesses or small and medium-sized treatment stations, their incineration equipment is often rudimentary, lacking precise temperature monitoring and control methods.

[0004] In addition, existing agricultural organic solid waste incineration devices generally suffer from incomplete combustion, which seriously affects the processing progress and efficiency. This is because agricultural organic solid waste itself has characteristics such as dispersed sources, complex composition, and high moisture content. In particular, straw materials have a loose texture and low bulk density, making it difficult to maintain stable and sustained combustion in ordinary incinerators. Secondly, agricultural solid waste often contains materials of different sizes and shapes. If it is directly put into the furnace for incineration without effective pretreatment, it is easy to cause uneven material accumulation in the furnace, poor air permeability, poor air circulation, local oxygen deficiency in the combustion zone, and failure to achieve complete combustion. Summary of the Invention

[0005] To address the aforementioned problems, the main objective of this invention is to provide an organic solid waste treatment device that can pre-treat organic solid waste, remove agricultural film residue from the waste, solve the problem of dioxin pollution caused by film residue in agricultural organic solid waste treatment, and improve the uniformity of solid waste before incineration, thereby increasing incineration efficiency.

[0013] Preferably, the air guide is provided with an air inlet pipe, which is connected to a crossflow fan. An adjustment plate is provided on the back of the air outlet of the air guide. A clamping plate is provided on the outer wall of the feed hopper. A square groove is provided on the clamping plate. The upper end of the adjustment plate passes through the square groove. Fastening bolts are provided on the clamping plate. The adjustment plate is fixed by the fastening bolts.

[0014] Preferably, the exhaust assembly includes an axial flow fan, an exhaust duct, and a flue. The axial flow fan is connected to the exhaust duct, which is a U-shaped pipe.

[0016] The beneficial effects of the present invention through the above technical solution include: (1) The organic solid waste treatment device of the present invention blocks the generation of dioxins from the source and realizes clean production. By adding a physical pretreatment and sorting link before incineration, the plastic scraps, clumps of plastic film and other high molecular polymers mixed in agricultural organic solid waste are effectively separated and collected. Since the main chlorine and carbon sources of plastic are removed in advance, the main ones entering the incineration process are simple organic biomass. Even if the incineration equipment that ordinary agricultural merchants cannot accurately control the temperature is used for treatment, a large amount of dioxins will not be generated due to the incomplete combustion of plastics. Thus, the problem of toxic substance emissions during the incineration process is solved from the source, and low-cost and clean treatment of agricultural solid waste is realized.

[0017] (2) In addition, the incineration mechanism of the organic solid waste treatment device of the present invention is equipped with a stirring component and a uniform component. The two work together to effectively enhance the disturbance and mixing of materials during the incineration process, which can increase the contact area between fuel and air in the incinerator, improve the air circulation in the furnace, and enable agricultural organic solid waste, especially high moisture content and low bulk density materials such as straw, to be fully and stably burned in the furnace, which greatly improves the combustion rate of materials.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] First Embodiment like Figure 1 As shown, this embodiment provides an organic solid waste treatment device, including a first conveying mechanism 1, a pretreatment mechanism 2, a second conveying mechanism 3, and an incineration mechanism 4 arranged in sequence. The first conveying mechanism 1 is used to convey the agricultural organic solid waste to be treated to the pretreatment mechanism 2; the pretreatment mechanism 2 is used to crush the organic solid waste; the second conveying mechanism 3 is used to convey the pretreated organic solid waste to the incineration mechanism 4; and the incineration mechanism 4 is used to fully incinerate the pretreated organic solid waste to achieve harmlessness and volume reduction.

[0028] Among them, such as Figure 4As shown, in this embodiment, the first conveying mechanism 1 and the second conveying mechanism 3 respectively include a conveyor belt 11, two side support plates 12, a front support frame 13, a rear support frame 14, and a driving component 15. The two side support plates 12 are located on both sides of the conveyor belt 11, serving to guide and prevent material spillage. The driving component 15 (e.g., a motor) is mounted on either side support plate 12, and drives the conveyor belt 11 to rotate through a transmission roller, thereby achieving stable material conveying.

[0029] In addition, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the incineration mechanism 4 includes an incinerator 40, an exhaust assembly, a stirring assembly, a uniform material assembly, and a flue gas purification assembly 50. The incinerator 40 has a waste inlet 51 on the side near the second conveying mechanism 3. The second conveying mechanism 3 transports the pretreated organic solid waste to the waste inlet 51 and into the incinerator 40. Furthermore, as... Figure 4 As shown, in this embodiment, the end of the side support plate 12 of the second conveying mechanism 3 is provided with a material guiding structure 30. The material guiding structure 30 is provided with a guide plate 31, two connecting shafts 32 and two connecting plates 33. One end of the connecting shaft 32 is fixedly connected to the outer side of the side support plate 12, and the other end is rotatably connected to the connecting plate 33. The guide plate 31 is rotatably arranged between the two connecting plates 33. By adjusting the angle of the guide plate 31, the drop point and drop direction of the material when it falls from the end of the second conveying mechanism 3 into the incineration mechanism 4 can be precisely controlled, which helps the material to be evenly distributed in the incinerator. In other embodiments, the guide plate 31 and the connecting plate 33 can also be flexibly rotatably connected, so that the bottom of the guide plate 31 and the lower edge of the opening of the waste inlet 51 are in direct contact.

[0030] Furthermore, the material leveling component in this embodiment can make the combustion of organic solid waste more uniform. The material leveling component is provided with an arc-shaped mesh plate 41, and the two ends of the arc-shaped mesh plate 41 are movably connected to the inner wall of the incinerator 40. Specifically, in order to realize the material leveling function of the arc-shaped mesh plate 41, arc-shaped clips are provided at both ends of the arc-shaped mesh plate 41. The arc-shaped clips are composed of an arc-shaped plate 411 and an arc-shaped outward expansion plate 412. Correspondingly, the inner wall of the incinerator 40 is provided with an arc-shaped sliding groove 45. The longitudinal section of the arc-shaped sliding groove 45 is L-shaped, and the arc-shaped plate 411 and the arc-shaped outward expansion plate 412 cooperate with the arc-shaped sliding groove 45.

[0031] Furthermore, the stirring component, which cooperates with the material equalization component, is located inside the arc surface of the arc-shaped mesh plate 41. The material to be incinerated is fed into the incinerator 40 through the second conveying mechanism 3 and falls onto the arc-shaped mesh plate 41. The stirring component stirs the material. Specifically, the stirring component is equipped with a drive motor 46, a stirring shaft 47, several connecting rods 48, and several scrapers 49. The stirring shaft 47, connecting rods 48, and scrapers 49 are all located inside the arc surface of the arc-shaped mesh plate 41. The drive motor 46 is installed on the outer wall of the incinerator 40, and the output end of the drive motor 46 is connected to any end of the stirring shaft 47. One end of the connecting rod 48 is fixed to the outer periphery of the stirring shaft 47, and the other end is perpendicularly connected to the scraper 49. When the drive motor 46 operates, it drives the stirring shaft 47 to rotate, causing the scraper 49 to move near the inner surface of the arc-shaped mesh plate 41. This stirs and agitates the material accumulated on the arc-shaped mesh plate 41. The movement trajectory of the scraper 49 matches the arc-shaped surface of the arc-shaped mesh plate 41, effectively turning the bottom layer of material to the top layer, increasing the contact area between the material and air, and promoting complete combustion. Furthermore, during the stirring process, since the arc-shaped plate 411 and the arc-shaped expansion plate 412 can slide within the arc-shaped groove 45, the two ends of the arc-shaped mesh plate 41 will automatically slide along the trajectory of the arc-shaped groove 45 as the material is stirred. That is, the arc-shaped mesh plate 41 reciprocates along the arc-shaped groove 45 within a certain range, thus turning over and flattening the layer of material accumulated on it, improving the uniformity of material distribution and air permeability. In other embodiments, the reciprocating motion of the arc-shaped mesh plate 41 can also be achieved through an external drive mechanism, such as a crank-connecting rod mechanism or a cam mechanism, further improving combustion completeness.

[0032] In this embodiment, the stirring component and the uniformizing component work together. The reciprocating sliding of the arc-shaped mesh plate 41 loosens the material layer as a whole and distributes it evenly, while the rotation of the stirring component provides localized and powerful agitation of the material. The combination of these two elements greatly enhances the disturbance and mixing of the material during combustion, improves air circulation within the furnace, and ensures that even high-moisture, low-bulk-density straw-like materials can achieve complete and stable combustion, significantly improving the burnout rate and combustion efficiency. Furthermore, in this embodiment, the incinerator 40 has an ash removal port 52 at its bottom side, through which completely burned ash can be discharged.

[0033] In addition, the exhaust assembly in this embodiment is used to transport the flue gas generated in the incinerator 40 to the flue gas purification assembly 50 for purification treatment. After treatment, the gas is discharged, or the treated hot air is heat recovered and connected to a heat exchanger to heat cold water to achieve the purpose of heating. The exhaust assembly includes an axial flow fan 42, an exhaust duct 43, and a flue 44. The axial flow fan 42 is connected to the exhaust duct 43, which is a U-shaped pipe. Both ends of the exhaust duct 43 are connected to the upper and lower sides of one side of the incinerator 40, respectively, and are located above and below the arc-shaped mesh plate 41. This design allows the exhaust assembly to form a circulating airflow within the incinerator 40, which is beneficial for replenishing oxygen and uniformizing the furnace temperature. The flue 44 is connected to the flue gas purification assembly 50 to lead out the flue gas for further treatment.

[0034] Second Embodiment The difference between the organic solid waste treatment device in this embodiment and the previous embodiment is that, in addition to crushing the organic solid waste, the pretreatment unit 2 of the organic solid waste treatment device in this embodiment can also screen and remove agricultural film residue mixed in it. Specifically, as shown in the figure... Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the pretreatment mechanism 2 is equipped with a mounting frame 20, a crushing component, a sieving component, and a waste removal component. The crushing component and the sieving component are fixed on the mounting frame 20. The crushing component is used to crush the input organic solid waste to destroy its original structure and make its size uniform. The sieving component is used to screen the crushed organic solid waste and screen out materials that do not meet the particle size requirements, especially agricultural film residues that are clumped together and have a certain weight. The waste removal component is used to separate and remove lighter plastic scraps and film fragments from the organic solid waste using physical methods such as airflow.

[0035] The following is combined Figure 6 and Figure 7 The specific structure of the pretreatment mechanism 2 is described in detail.

[0036] The crushing assembly in this embodiment includes a feeding bin 21, a servo motor 22, a first crushing roller shaft (not shown in the figure), and a second crushing roller shaft 23. The feeding bin 21 has a feed inlet 211 at the top and a discharge outlet 212 at the bottom. The first crushing roller shaft and the second crushing roller shaft 23 are parallel and rotatably arranged inside the feeding bin 21, and their surfaces are provided with mutually cooperating crushing teeth. In addition, one end of the first crushing roller shaft is provided with a rotating shaft, which passes through the feeding bin 21 and is fixedly connected to the center of a driven gear 221. The servo motor 22 is fixed on the side wall of the feeding bin 21, and the output end of the servo motor 22 is fixedly connected to the center of a drive gear 222. The drive gear 222 meshes with the driven gear 221. When the servo motor 22 starts, the drive gear 222 drives the driven gear 221 to rotate, thereby rotating the first crushing roller shaft. At the same time, through gear meshing or chain transmission, the second crushing roller shaft 23 also rotates in the opposite direction, extruding, shearing, and crushing the material entering the feeding bin 21.

[0037] Furthermore, the screening assembly in this embodiment includes a screen 24, a base plate 25, and a mounting side plate 26. The screen 24 and the base plate 25 are uniformly inclined so that the material can automatically slide down under gravity. The screen 24 is located above the base plate 25, and the aperture of the screen 24 can be selected according to the size of the plastic fragments to be removed. The higher end of the screen 24 is located below the discharge port 212 and is used to receive the crushed material. The crushed material falls onto the inclined screen 24, where organic particles smaller than the screen aperture pass through the screen and fall onto the base plate 25 below, while larger materials, such as clumps of plastic film, slide down the surface of the screen 24. The other end of the screen 24 and the base plate 25 are fixed by the mounting side plate 26 to form an integrated screening unit. The organic waste after screening falls through the outlet provided at the outer end of the base plate 25 to the starting end of the conveyor belt 11 of the second conveying mechanism 3 and continues to be transported to the next incineration stage.

[0038] In addition, the impurity removal component of this embodiment is provided with a collection chamber 27 and an air guide 28. The collection chamber 27 is located on the side of the mounting frame 20 away from the screen 24, that is, on the outside of the lower end of the screen 24. The air guide 28 is located above the screen 24 and on the other side opposite to the discharge port 212 and the collection chamber 27. That is, the air guide 28 is located above the higher end of the screen 24, and its air outlet faces the surface of the screen 24 and blows air towards the collection chamber 27. The collection chamber 27 is provided with an inlet 278, which is arranged opposite to the air guide 28 so that the airflow blows lightweight plastic fragments into the collection chamber 27.

[0039] In this embodiment, the air guide 28 is provided with an air inlet pipe (not shown in the figure), which is connected to a crossflow fan to provide a stable and uniform horizontal airflow. In order to adjust the height of the air guide 28, an adjusting plate 281 is provided on the back of the air outlet of the air guide 28. A clamping plate 213 is provided on the corresponding outer wall of the feed hopper 21. The clamping plate 213 is provided with a square groove, and the upper end of the adjusting plate 281 passes through the square groove. The clamping plate 213 is provided with a fastening bolt 282. The position of the adjusting plate 281 is fixed by the fastening bolt 282. By loosening the fastening bolt 282, the adjusting plate 281 can be moved up and down to change the height of the air outlet of the air guide 28, thereby precisely controlling the airflow's screening effect on the material.

[0040] Furthermore, on the screen 24, the crushed material slides down under the influence of tilting vibration and gravity. During this process, the horizontal airflow blown out from the air guide 28 acts on the sliding material. Since the plastic film residue and plastic shavings are relatively light, they are blown up by the airflow, passing over the edge of the screen 24 or being blown up directly during the fall, and entering the collection bin 27 through the inlet 278. The heavier organic particles (such as chopped straw) continue to fall onto the screen 24, and finally fall from the screen 24 into the bottom plate 25, and finally enter the second conveying mechanism 3 below from the outlet of the bottom plate 25, and are sent to the incineration mechanism 4.

[0041] To more effectively collect and compress residual plastic film, such as Figure 6 As shown, the bottom of the collection chamber 27 is provided with a pull-out receiving slot 271 for collecting and easily removing blown-in plastic fragments and residual film. Additionally, the side of the collection chamber 27 is provided with a debris removal port 272, located on either side of the pull-out receiving slot 271, for auxiliary cleaning when necessary. Furthermore, the top of the collection chamber 27 is provided with a mounting plate 273, on which a hydraulic cylinder 274 is fixedly mounted. The top of the collection chamber 27 has a through-hole 275, within which a push rod 276 is installed. The lower end of the push rod 276 is fixedly connected to the top surface of a pressing plate 277, and the upper end is fixedly connected to the lower end of the piston rod of the hydraulic cylinder 274. When a certain amount of lightweight plastic fragments accumulates in the collection chamber 27, the hydraulic cylinder 274 can be activated, driving the push rod 276 and the pressing plate 277 to move downwards, compressing the loose plastic fragments in the pull-out receiving slot 271, thereby increasing the storage capacity of the receiving slot and reducing the cleaning frequency.

[0042] In summary, the organic solid waste treatment device of the present invention operates as follows in treating organic solid waste: First, agricultural organic solid waste mixed with agricultural film residue is fed into the feed hopper 21 of the pretreatment unit 2 by the first conveying mechanism 1. In the crushing assembly, the material is crushed by the first crushing roller and the second crushing roller 23. The crushed material falls onto the inclined screen 24. Under the action of gravity, the material slides down the screen 24, while the horizontal airflow blown out by the air guide 28 blows the lighter plastic chips and film fragments into the collection hopper 27, where they are compressed and stored. The organic material after removing the plastic falls from the screen 24 into the bottom plate 25 and from the end of the bottom plate 25 into the second conveying mechanism 3. The clumps of plastic film do not pass through the screen 24 and fall from the outlet at the end of the screen 24 for collection. The agricultural film residue collected in both places can be transported to power plants or incineration plants and other professional institutions for efficient and harmless treatment.

[0043] Next, the second conveying mechanism 3 transports the clean organic fragments to the incinerator 40 of the incineration mechanism 4, where the material falls onto the arc-shaped mesh plate 41. During incineration, the drive motor 46 drives the stirring assembly to continuously stir and agitate the material, while the arc-shaped mesh plate 41 slides back and forth along the arc-shaped chute 45, flattening and loosening the material. This allows the material to fully contact the air, achieving complete combustion. The high-temperature flue gas generated by combustion is partially recycled within the furnace by the exhaust assembly, while the other part enters the flue gas purification assembly 50 through the flue duct 44 and is discharged after meeting the standards.

[0044] In summary, this invention effectively removes agricultural film residue from agricultural organic solid waste through the pretreatment mechanism 2, eliminating the conditions for dioxin formation at the source. Simultaneously, the coordinated operation of the stirring and homogenizing components in the incineration mechanism 4 ensures complete combustion of the material, improving processing efficiency. This device has a reasonable structural design and stable operation, making it highly suitable for ordinary agricultural businesses or small and medium-sized processing plants, and possesses significant value for widespread application.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.
