Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer processing, in particular to an organic fertilizer fermentation device. Background Art

[0002] Organic fertilizer refers to fertilizer made from animal excrement or animal and plant residues and other organic-rich byproduct resources, which are fermented and decomposed, including human feces, manure, compost, biogas fertilizer, etc. Most of the nutrients contained in organic fertilizers are in an organic state, which is difficult for crops to use directly. Organic fertilizers need to be fermented by microorganisms to release a variety of nutrients before nutrients can be supplied to crops. The current organic fertilizer raw materials are generally dry and wet materials mixed together for fermentation. The fermentation temperature and cycle of organic fertilizers will vary with changes in ambient temperature, material moisture content, stirring conditions, and changes in raw and auxiliary materials.

[0003] For example, a Chinese invention patent with the patent authorization announcement number CN116120106B provides an organic fertilizer fermentation device, which can effectively reduce agglomeration and improve fertility. At the same time, it can allow the organic fertilizer to be more fully in contact with the air, and the moisture in the organic fertilizer can be more evenly distributed, so as to more effectively improve the fermentation efficiency of the organic fertilizer. An organic fertilizer fermentation device includes a bottom support seat, a lower disc and an upper disc, etc.; the lower disc is arranged on one side of the bottom support seat, and the upper disc is arranged on the side of the bottom support seat away from the lower disc. The present invention rotates and turns the organic fertilizer raw materials by rotating the circular frame. The rotation of the rotating circular frame will drive a number of driving strips to rotate, further turning the organic fertilizer raw materials in the rotating circular frame, fully mixing the dry and wet materials of the organic fertilizer raw materials, and keeping the organic fertilizer raw materials loose at the same time, providing conditions for the fermentation of the organic fertilizer raw materials, and allowing the organic fertilizer to ferment quickly.

[0004] Although the above device has achieved certain results in reducing the agglomeration problem of organic fertilizer raw materials, its limitations are also clearly revealed during the actual operation. Especially in the raw material input link, the organic fertilizer raw materials are added to one side of the rotating circular frame through the discharge pipe. This practice often leads to uneven distribution of raw materials in the device. Specifically, the raw materials on the side where the discharge pipe is located are piled up like a mountain, while the raw materials on the other side are relatively less. Although the device is equipped with a stirring device, unfortunately, this stirring device can only stir along the radial direction of the rotating circular frame, and cannot promote the effective flow of materials in the axial direction. This uneven material distribution will lead to inconsistent fermentation degrees on both sides, seriously weakening the overall fermentation effect; in addition, the pollutant gases released during the fermentation of organic fertilizers, if discharged directly without treatment, will not only deteriorate the surrounding environment, but may also pose a health threat to workers who are exposed to this environment for a long time. Summary of the invention

[0005] The invention discloses an organic fertilizer fermentation device, which solves the problems of uneven raw material distribution, limited effect of a stirring device, and direct emission of pollutant gas generated by fermentation, which deteriorates the environment and threatens the health of workers in traditional organic fertilizer fermentation devices.

The external oxygen supply pipeline is connected to the open end of the movable shaft by using an external hose in advance, so that oxygen can be provided to the fermentation cylinder through the movable shaft and the air supply component in turn; then, the fermentation cylinder is driven to rotate around its own axis by using the first driving component, so that the raw material in the fermentation cylinder can be driven to move radially along the fermentation cylinder, and since the parts of the two movable shafts located in the fermentation cylinder are provided with stirring components, the raw material can be radially stirred; at the same time, the two movable shafts can be driven to approach or move away from each other by the second driving component, so that the stirring component can be driven to move horizontally in the fermentation cylinder, thereby driving the organic fertilizer raw material to move along the axial direction of the fermentation cylinder, so that the raw material in the fermentation cylinder is distributed more evenly, so that the consistency of the fermentation degree of the organic fertilizer can be maintained, and the fermentation efficiency of the organic fertilizer can be effectively improved; and the pollutant gas generated during the fermentation process enters the tail gas treatment component through the exhaust pipe and the connecting pipe in turn for adsorption treatment, thereby preventing it from being directly discharged into the air to cause environmental pollution and personal injury.

[0032] like Figure 2 and Figure 3 As shown, the stirring assembly includes several groups of turning rods 31 uniformly fixed to the lower half of the movable shaft 3, and each group of turning rods 31 is arranged to surround the lower half of the movable shaft 3. The end of each turning rod 31 not fixed to the movable shaft 3 is fixed with a turning block 311 that fits the inner wall of the fermentation cylinder 4, and the bottom of each movable shaft 3 located in the fermentation cylinder 4 is also uniformly fixed with several crushing plates 32. The crushing plates 32 can divide the larger organic fertilizer raw materials into small pieces, so that the raw materials in the fermentation cylinder 4 are looser, so that the raw materials can be more fully contacted with oxygen, and then more effectively improve the fermentation efficiency and fermentation effect of the organic fertilizer; the turning rods 31 and the turning blocks 311 can drive the organic fertilizer raw materials divided into small pieces to move along the radial and axial direction of the fermentation cylinder 4, so that the raw materials in the fermentation cylinder 4 are more evenly distributed, thereby maintaining the consistency of the fermentation degree of the organic fertilizer, and effectively improving the fermentation efficiency of the organic fertilizer.

[0033] like Figure 2 and Figure 3As shown, the part of each movable shaft 3 located in the fermentation cylinder 4 is coaxially provided with two vertical fixing rings 33, the outer wall of the fixing ring 33 is in contact with the inner wall of the fermentation cylinder 4, and the plurality of groups of flipping rods 31, flipping blocks 311 and a plurality of crushing plates 32 arranged on the movable shaft 3 are all located between the corresponding two fixing rings 33, and a plurality of connecting rods 331 are fixed on each movable shaft 3, and the plurality of connecting rods 331 are respectively fixedly connected with the inner wall of the corresponding fixing ring 33. Further, the distance between the two fixing rings 33 located on the same movable shaft 3 is equal to one-fourth of the axial length of the fermentation cylinder 4; by providing the connecting rods 331 and the fixing ring 33, not only can the movable shaft 3 play a limiting role in the process of horizontal movement to prevent the movable shaft 3 from excessively moving out of the fermentation cylinder 4, but also can scrape the inner wall of the fermentation cylinder 4 in the process of its axial movement along the fermentation cylinder 4, thereby preventing the material from sticking to the inner wall of the fermentation cylinder 4 and causing material loss.

[0034] like Figure 1 and Figure 6 As shown, the first driving assembly includes a vertical rotating shaft 12 rotatably connected to the center of the top surface of the bottom plate 1, a motor 11 is provided in the bottom plate 1 for driving the rotating shaft 12 to rotate around its own axis, a horizontal rotating rod 16 is rotatably connected between the two support columns 2, and the rotating rod 16 is located between the rotating shaft 12 and the fermentation cylinder 4, a bevel gear 17 is fixed to the top of the rotating shaft 12 and the surface of the rotating rod 16, and the two bevel gears 17 are meshed, and two vertical gears 18 are fixed to the surface of the rotating shaft 12, and two gear rings 43 are vertically fixed to the outer surface of the fermentation cylinder 4, which are respectively meshed with the corresponding gears 18, and the two gear rings 43 are symmetrically located on both sides of the fermentation cylinder 4. Start the motor 11, and the output end of the motor 11 drives the rotating shaft 12 to rotate around its own axis, thereby driving the rotating rod 16 to rotate through the two meshing bevel gears 17, and then driving the corresponding gear rings 43 to rotate through the two gears 18, so that the fermentation cylinder 4 can be driven to rotate around its own axis, so that the raw materials in the fermentation cylinder 4 are turned over.

[0035] like Figure 1 and Figure 7As shown, the second driving assembly includes a horizontal turntable 13 fixed to the surface of the rotating shaft 12, and a ring groove 131 is opened on the top surface of the turntable 13, and the ring groove 131 forms a ring structure with thick ends and thin middle. Horizontal movable rods 14 are respectively slidably connected to the two support columns 2, and movable blocks 141 that are clamped with both sides of the ring groove 131 are respectively fixed on the bottom surfaces of the opposite ends of the two movable rods 14. The ends of the two movable rods 14 that are away from each other pass through the corresponding support column 2 and extend to the outside of the support column 2. The ends of the two movable rods 14 located outside the support column 2 are respectively fixed with vertical support rods 15, and the ends of the two support rods 15 away from the movable rods 14 are respectively fixedly connected to the ends of the corresponding movable shafts 3 located outside the support column 2. Furthermore, the second spring 142 is sleeved on the surface of the two movable rods 14 located outside the support column 2, and the second spring 142 is located between the corresponding support column 2 and the support rod 15; further, the distance from the thick ends of the annular groove 131 to the center of the turntable 13 minus the distance from the thin end in the middle of the annular groove 131 to the center of the turntable 13 is equal to one-fourth of the axial length of the fermentation cylinder 4; when the output end of the motor 11 drives the rotating shaft 12 to rotate around its own axis, the turntable 13 will rotate with the rotating shaft 12. Since the top surface of the turntable 13 is provided with an annular groove 131 and the annular groove 131 forms a ring-shaped structure with thick ends at both ends and thin in the middle, the distance between the movable block 141 and the axis of the rotating shaft 12 can be continuously changed during the movement of the movable block 141 along the annular groove 131, thereby driving the corresponding movable rod 14 to move left and right, and then driving the two movable shafts 3 to move closer or farther from each other through the corresponding support rod 15, the stirring component can be used to perform axial stirring operation on the organic fertilizer raw materials in the fermentation cylinder 4, so that the raw materials in the fermentation cylinder 4 are more evenly distributed.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, the air supply assembly includes an air guide pipe 34 which is connected to the top surface of the movable shaft 3 and is vertical.

A filter cover 37 surrounding the plurality of air jets 36 is fixed to the bottom surface of the air collecting box 35. A filter screen 51 is provided at one end of the exhaust pipe 5 located in the fermentation cylinder 4. Furthermore, the top surface of the air collecting box 35 is an arc-shaped surface, which can fit tightly with the inner wall of the fermentation cylinder 4, thereby saving space utilization, and the bottom surface of the air collecting box 35 is preferably set as a plane, or a convex surface opposite to the top surface, so that the plurality of air jets 36 can spray oxygen evenly. The external oxygen supply pipeline is connected to the open end of the movable shaft 3 by using an external hose. Since the movable shaft 3 is a hollow structure, oxygen can be sequentially introduced into the air collecting box 35 through the movable shaft 3 and the air guide pipe 34, and then evenly sprayed into the fermentation cylinder 4 through the plurality of air jets 36. Organic fertilizer raw materials, and because the two movable shafts 3 can be close to or away from each other, the air jet 36 can spray oxygen more evenly, so that the raw materials can be in contact with oxygen more fully, thereby more effectively improving the fermentation efficiency and fermentation effect of the organic fertilizer; the setting of the filter cover 37 and the filter net 51 can prevent the organic fertilizer raw materials from entering the air jet 36 and the exhaust pipe 5 during the stirring process and causing blockage; it is worth noting that the length of the external hose meets the margin requirement when the movable shaft 3 moves horizontally, and can be adaptively bent in conjunction with the horizontal movement of the movable shaft 3.

Specifically, a mounting seat 711 is fixed to the outer wall of the exhaust gas treatment cylinder 7, and the adsorption liquid tank 71 is fixed on the mounting seat 711. The mounting seat 711 can fix and support the adsorption liquid tank 71; the adsorption liquid tank 71 is also connected to a liquid inlet pipe 712, and the adsorption liquid can be replenished into the adsorption liquid tank 71 through the liquid inlet pipe 712; a valve 76 is provided on the drain pipe 75, which can control the discharge of the adsorption liquid in the exhaust gas treatment cylinder 7; further, the exhaust pipe 82 is preferably arranged in the middle and lower part of the exhaust gas treatment cylinder 7, so that the bottom end of the exhaust gas treatment cylinder 7 can store a part of the adsorption liquid to prevent the pollutant gas from being directly discharged from the drain pipe 75; further, the connecting pipe 6 and the exhaust pipe 82 are preferably arranged on both sides of the exhaust gas treatment cylinder 7, The pollutant gas can pass through a longer path, so that it can be more fully neutralized and adsorbed by the adsorption liquid; the water pump 721 is started in advance, and the adsorption liquid in the adsorption liquid tank 71 is introduced into a plurality of water diversion branches 73 through the water guide main pipe 72, and is evenly sprayed into the waste gas treatment tube 7 through a plurality of water spray heads 74. When the pollutant gas generated during the fermentation process enters the waste gas treatment tube 7 through the waste gas pipe 5 and the connecting pipe 6 in turn, the pollutant gas can be neutralized and adsorbed. After being neutralized by the adsorption liquid, the gas enters the activated carbon adsorption box 8 through the exhaust pipe 82, and is finally discharged harmlessly into the air, and the adsorption liquid that absorbs the pollutants is discharged from the drain pipe 75 to the external wastewater treatment device for treatment.

[0038] like Figure 8 and Fig. 9As shown, the open ends of the two movable shafts 3 are respectively provided with flow control components for controlling the oxygen flow rate, and the flow control components include a movable plate 38 horizontally rotatably connected to the inner wall of the open end of the movable shaft 3, a horizontal fixed plate 385 is provided above the movable plate 38, and the fixed plate 385 is fixedly connected to the inner wall of the open end of the movable shaft 3, a channel is provided at the center of the movable plate 38 and the fixed plate 385, and a plurality of inclined slide grooves 382 surrounding the channel are provided on the top surface of the movable plate 38, a slider 383 is respectively clamped in each slide groove 382, ​​and a limiting flow plate 384 is respectively fixed on each slider 383, and a plurality of The limiting plates 384 are all located between the movable plate 38 and the fixed plate 385. A plurality of fixed blocks 386 are fixed to the bottom surface of the fixed plate 385. The plurality of fixed blocks 386 are rotatably connected to the corresponding outer edges of the limiting plates 384 away from the slider 383. A groove 39 is provided on the outer wall of the open end of the movable shaft 3. A block 381 corresponding to the groove 39 is fixed to the side of the movable plate 38. When the block 381 moves along the groove 39, the limiting plates 384 can approach or move away from each other, and when the limiting plates 384 are tightly attached, the limiting plates 384 can completely cover the channel of the movable plate 38. Manually rotating the block 381 horizontally so that the block 381 moves along the groove 39 can drive the movable plate 38 to rotate. Due to the setting of the slide groove 382, ​​the slider 383 will drive one side of the limiting plate 384 to rotate around the corresponding fixed block 386, thereby driving the plurality of limiting plates 384 to move closer to or farther away from each other, so that the plurality of limiting plates 384 can fully open, half open or fully cover the channel, thereby achieving the purpose of controlling the oxygen flow rate; at the same time, when the oxygen supply is stopped, the plurality of limiting plates 384 are used to completely cover the channel, which can prevent the polluted gas from flowing back along the movable shaft 3; further, the portion of the exhaust pipe 5 that passes through the movable shaft 3 is provided with a rubber ring 52, and the inner and outer sides of the rubber ring 52 are respectively fixedly connected to the outer wall of the exhaust pipe 5 and the inner wall of the movable shaft 3, so as to prevent gas leakage from the penetration.

[0039] like Fig.10As shown, the diameter of the connecting pipe 6 is larger than the diameter of the exhaust pipe 5, and a vertical limiting ring 53 is fixed to the outer wall of the end of the exhaust pipe 5 away from the fermentation cylinder 4 and the inner wall of the end of the connecting pipe 6 away from the exhaust gas treatment component. The two limiting rings 53 are respectively fixed to the opposite sides with vertical sealing rings 61, and a first spring 62 is fixed between the two sealing rings 61, and the first spring 62 is sleeved on the surface of the exhaust pipe 5. The limiting ring 53 can limit the relative movement of the exhaust pipe 5 and the connecting pipe 6 to prevent the exhaust pipe 5 from completely sliding out of the connecting pipe 6; the sealing ring 61 can effectively prevent the pollutant gas from leaking from the connection between the exhaust pipe 5 and the connecting pipe 6 to cause environmental pollution; the first spring 62 can make it more convenient for the exhaust pipe 5 to move in the connecting pipe 6; it is worth noting that during installation, the exhaust pipe 5, the sealing ring 61 and the first spring 62 can be installed first, and then the limiting ring 53 on the connecting pipe 6 can be fixed to the connecting pipe 6.

[0040] like Figure 1 As shown, a plurality of supports 9 are fixed to the bottom of the exhaust gas treatment cylinder 7 and the activated carbon adsorption box 8, respectively; and a handle 42 is fixed to the cover plate 41. The supports 9 can fix and support the exhaust gas treatment cylinder 7 and the activated carbon adsorption box 8; and the handle 42 can facilitate the staff to open or close the cover plate 41.

[0041] When in use, first, the cover plate 41 is opened by the handle 42, the organic fertilizer raw material is poured into the fermentation cylinder 4, and then the cover plate 41 is closed, and the external oxygen supply pipeline is connected to the open end of the movable shaft 3 by using an external hose in advance. Since the movable shaft 3 is a hollow structure, oxygen can be sequentially passed through the movable shaft 3 and the air guide pipe 34 into the air collecting box 35, and then the organic fertilizer raw material in the fermentation cylinder 4 is evenly sprayed through a plurality of spray heads 36, so that oxygen can be provided to the fermentation cylinder 4;

[0042] When it is necessary to control the ejection amount of oxygen in the fermentation cylinder 4, the block 381 is manually rotated horizontally so that the block 381 moves along the groove 39, which can drive the movable plate 38 to rotate. Due to the setting of the slide groove 382, ​​the slider 383 will drive one side of the limiting plate 384 to rotate around the corresponding fixed block 386, thereby driving the plurality of limiting plates 384 to move closer to or away from each other, so that the plurality of limiting plates 384 can fully open, half open or fully cover the channel, thereby achieving the purpose of controlling the oxygen flow rate; at the same time, when the oxygen supply is stopped, the plurality of limiting plates 384 are used to completely cover the channel, which can prevent the polluted gas from flowing back along the movable shaft 3;

[0043] After the raw materials are poured into the fermentation cylinder 4, the motor 11 is started, and the output end of the motor 11 drives the rotating shaft 12 to rotate around its own axis, thereby driving the rotating rod 16 to rotate through two meshing bevel gears 17, and then driving the corresponding gear ring 43 to rotate through two gears 18, so that the fermentation cylinder 4 can be driven to rotate around its own axis, so that the raw materials in the fermentation cylinder 4 move along the radial direction of the fermentation cylinder 4;

[0044] When the output end of the motor 11 drives the rotating shaft 12 to rotate around its own axis, the turntable 13 will rotate with the rotating shaft 12. Since the top surface of the turntable 13 is provided with an annular groove 131 and the annular groove 131 forms an annular structure with thick ends and thin middle, the movable block 141 can be moved along the annular groove 131. The distance between the movable block 141 and the axis of the rotating shaft 12 is constantly changing, thereby driving the corresponding movable rod 14 to move left and right, and then driving the two movable shafts 3 to move closer to or away from each other through the corresponding support rod 15, the stirring assembly can be used to perform axial stirring operation on the organic fertilizer raw materials in the fermentation cylinder 4, so that the raw materials in the fermentation cylinder 4 are distributed more evenly, so that the consistency of the fermentation degree of the organic fertilizer can be maintained, and the fermentation efficiency of the organic fertilizer is effectively improved;

[0045] When the fermentation operation in the fermentation cylinder 4 begins, the water pump 721 is started in advance, and the adsorption liquid in the adsorption liquid tank 71 is introduced into a plurality of water diversion branches 73 through the water guide main pipe 72, and is evenly sprayed into the waste gas treatment cylinder 7 through a plurality of water spray heads 74. When the pollutant gas generated during the fermentation process enters the waste gas treatment cylinder 7 through the waste gas pipe 5 and the connecting pipe 6 in turn, the pollutant gas can be neutralized and adsorbed. After being neutralized by the adsorption liquid, the gas enters the activated carbon adsorption box 8 through the exhaust pipe 82, and is finally discharged harmlessly into the air.
