Description

Technical Field

[0001] The present invention relates to the technical field of livestock and poultry excrement fermentation, and in particular to a livestock and poultry excrement fermentation device and a method thereof. Background Art

[0002] Livestock and poultry manure mainly refers to a type of rural solid waste generated in the livestock and poultry farming industry, including pig manure, cow manure, sheep manure, chicken manure and duck manure. Livestock and poultry manure has always been regarded as an important source of soil fertilizer. Therefore, livestock and poultry manure is mostly applied on-site. Animal excrement contains rich organic matter and nutrients such as nitrogen, phosphorus, and potassium. It can also provide crops with calcium, magnesium, sulfur and other minerals and trace elements, meeting the needs of crops for multiple nutrients during growth. Livestock and poultry manure composting uses livestock and poultry manure as the main raw material.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 6 As shown, the present invention provides a fermentation device and method for livestock and poultry manure, including: a fermentation tank 1, which is connected to a feed pipe 4 and a discharge pipe 5, and valves are installed on the feed pipe 4 and the discharge pipe 5; a stirring mechanism 2 for stirring the material; and a spraying mechanism 3 for spraying additives into the material.

[0025] The material in the present invention includes solid feces and a carbon source added in proportion to the solid feces; the moisture content of the solid feces is controlled at 50% to 60%, and the carbon source is preferably rice husk, straw, or sawdust.

[0026] A certain amount of material is added to the fermentation tank 1 through the feed pipe 4. During the material addition process, the valve on the discharge pipe 5 is in a closed state. When a certain amount of material is added to the fermentation tank 1, the valve on the feed pipe 4 is closed. When the material fermentation is completed, the door on the discharge pipe 5 is opened and the fermented material is discharged.

[0027] It should be noted that the fermentation tank 1 is provided with a heating device, preferably an electric heating device, so that the temperature inside the fermentation tank 1 can be controlled within the required range; and the fermentation tank 1 is provided with an air source, preferably an air pump, so that oxygen can be evenly supplied to the material to meet the metabolic needs of aerobic microorganisms.

[0028] The stirring mechanism 2 includes: a stirring shaft 21 rotatably mounted on the fermentation tank 1; a power source 22 for driving the stirring shaft 21 to rotate, a mounting frame fixedly mounted on the fermentation tank 1, and the power source 22 fixedly mounted on the mounting frame; a rotating plate 26 and a spiral blade 23 fixedly mounted on the stirring shaft 21; a scraper 24 fixedly mounted on the end of the stirring shaft 21, the scraper 24 being arranged to fit the inner wall of the fermentation tank 1; a stirring plate 25 fixedly mounted on the scraper 24; and a crushing assembly 27 for crushing the material; the crushing assembly Component 27 includes: a collecting hopper 273 slidably installed in the fermentation tank 1, a fixed plate fixedly installed in the fermentation tank 1, a circular opening is opened on the fixed plate, and the discharge end of the collecting hopper 273 is slidably installed in the circular opening. Since the collecting hopper 273 is set in a cone shape, the collecting hopper 273 can be supported and limited by the fixed plate; a rotating drum 271 fixedly mounted on the stirring shaft 21; a crushing knife 272 fixedly mounted on the rotating drum 271; and a vibration unit 274 that causes the collecting hopper 273 to vibrate.

[0029] The rotating plate 26 is petal-shaped, and the top of the rotating plate 26 is arc-shaped.

[0030] When the material enters the fermentation tank 1 through the feed pipe 4, the power source 22 is started to drive the stirring shaft 21 to rotate, and the stirring shaft 21 drives the rotating drum 271, the rotating plate 26, the spiral blade 23, and the scraper 24 to rotate, and drives the crushing knife 272 and the stirring plate 25 to rotate.

[0031] The material entering the fermentation tank 1 first falls into the collecting hopper 273. At this time, the material can be crushed by the rotation of the crushing blade 272, thereby crushing the material into smaller blocks, which is conducive to the full mixing of the material and the additive, and can relieve the pressure of the stirring mechanism 2 when stirring the material. In addition, the rotation of the crushing blade 272 can stir the material and realize the pre-mixing of the material.

[0032] The crushed material falls on the top of the rotating plate 26 through the discharge end of the collecting hopper 273. Since the top of the rotating plate 26 is arranged in an arc shape, the rotation of the rotating plate 26 allows the material to be dispersed at the bottom of the inner cavity of the fermentation tank 1 under the action of centrifugal force, thereby avoiding material accumulation and improving the mixing efficiency of the material.

[0033] By rotating the spiral blades 23 , the material can be turned from bottom to top, thereby turning the material at the bottom of the fermentation tank 1 to the top, achieving longitudinal stirring of the material and improving the uniformity of material mixing.

[0034] By rotating the scraper 24 , the material attached to the inner wall of the fermentation tank 1 can be scraped off, so that the scraped material is mixed with the material in the fermentation tank 1 , thereby achieving horizontal stirring of the material and further improving the uniformity of the material mixing.

[0035] When the scraper 24 rotates, it can drive the stirring blade to rotate, and can disperse the material turning from bottom to top, thereby expanding the horizontal stirring range of the material and further improving the uniformity of material mixing.

[0036] When the fermentation of the material is completed, the power source 22 is started to rotate in the reverse direction. At this time, the spiral blades 23 can drive the material to move from top to bottom, so that the material actively moves to the discharge pipe 5, achieving the purpose of rapid discharge and avoiding blockage of the discharge pipe 5.

[0037] Since the spiral blade 23 is located above the discharge pipe 5, it is convenient to flip the material at the discharge pipe 5 from bottom to top when the spiral blade 23 is rotating forward; when the spiral blade 23 is rotating backward, it drives the material to move from top to bottom for rapid discharge to avoid blockage.

[0038] In the present invention, the stirring mechanism 2 is provided to crush the material, and the crushed material can be stirred horizontally and vertically, thereby achieving comprehensive stirring of the material in the fermentation tank 1, making the overall temperature of the material in the fermentation tank 1 uniform, thereby improving the fermentation effect. When the fermentation of the material is completed, the material can be quickly discharged.

[0039] It is supplemented here that the power source 22 is preferably an electric motor.

[0040] The spraying mechanism 3 includes: an annular tube 31 fixedly mounted on the bottom of the fixed plate; a nozzle 32 connected to the annular tube 31, wherein a plurality of nozzles 32 are provided, and the plurality of nozzles 32 are evenly distributed along the circumference of the annular tube 31, and the plurality of nozzles 32 are hingedly mounted on the bottom of the annular tube 31, and the annular tube 31 and the nozzle 32 are connected through a conveying pipe; a linkage spring 33 for driving the nozzle 32 to reset, wherein one end of the linkage spring 33 is fixedly connected to the nozzle 32, and the other end is fixedly connected to the bottom of the annular tube 31; a liquid storage tank 34 fixedly mounted on the fermentation tank 1; a conveying component 35 for conveying the additive in the liquid storage tank 34 to the annular tube 31; and a mixing component 36 for uniformly mixing the additive in the liquid storage tank 34.

[0041] The liquid storage tank 34 stores additives, which are preferably liquid bacterial agents, that is, the bacterial agent is diluted at a ratio of 1:50-1:100 (such as 1 kg bacterial agent + 50 kg water). The additive is sprayed into the material to allow the material to ferment.

[0042] When the power source 22 is started, the conveying assembly 35 can be driven to operate. The conveying assembly 35 includes: a driven bevel gear 352 rotatably mounted on the liquid storage tank 34; a driving bevel gear 351 meshingly connected to the driven bevel gear 352, and the driving bevel gear 351 is fixedly sleeved on the stirring shaft 21; a circular plate 353 coaxially connected to the driven bevel gear 352; a connecting rod 354 fixedly mounted on the circular plate 353; a linkage frame 355 slidably connected to the connecting rod 354, a slide groove is provided on the linkage frame 355, and the connecting rod 354 is slidably mounted in the slide groove; a capsule 356 fixedly connected to the linkage member, the other side of the capsule 356 is fixedly connected to the inner wall of the liquid storage tank 34, the capsule 356 is communicated with the liquid storage tank 34 through a liquid inlet pipe, and the capsule 356 is communicated with the annular pipe 31 through a liquid outlet pipe, the liquid inlet pipe is installed with a first one-way valve, and the liquid outlet pipe is installed with a second one-way valve.

[0043] A limit block is installed on the linkage, and a limit groove is opened on the inner wall of the liquid storage tank 34 along the axial direction of the liquid storage tank 34. The limit block is slidably installed in the limit groove. Under the limiting action of the limit block and the limit groove, the linkage can only move along the axial direction of the liquid storage tank 34.

[0044] That is, the power source 22 drives the stirring shaft 21 to rotate, the stirring shaft 21 drives the driving bevel gear 351 to rotate, the driving bevel gear 351 drives the driven bevel gear 352 to rotate, the driven bevel gear 352 drives the circular plate 353 to rotate, and the circular plate 353 drives the connecting rod 354 to rotate. Driven by the connecting rod 354, the linkage frame 355 reciprocates up and down along the axial direction of the liquid storage tank 34, thereby driving the capsule 356 to recover and compress.

[0045] When the linkage frame 355 moves downward, it drives the capsule 356 to recover. At this time, the capsule 356 generates suction, the first one-way valve opens, the second one-way valve closes, and the additive in the liquid storage tank 34 enters the capsule 356 through the liquid inlet pipe; When the linkage frame 355 moves upward, it drives the capsule 356 to compress. At this time, the additive in the capsule 356 is squeezed, the first one-way valve is closed, and the second one-way valve is opened. The additive in the capsule 356 enters the annular tube 31 through the liquid outlet pipe and is sprayed out through the delivery pipe and the nozzle 32 in sequence.

[0046] Since there are multiple nozzles 32, the additive can be evenly sprayed on the surface of the material. At the same time, when the rotating plate 26 rotates, the nozzle 32 moves along the petal-shaped edge of the rotating plate 26, and cooperates with the elastic force of the linkage spring 33 to make the multiple nozzles 32 synchronously retract or expand, thereby realizing the swing of the nozzle 32, expanding the spraying range of the nozzle 32, and making the additive sprayed evenly, which is conducive to the subsequent mixing of the material and the additive.

[0047] Additives are sprayed while the material is being fed, so that the additives are better mixed with the material. After the feeding is completed, the additive spraying is stopped.

[0048] In addition, while feeding and spraying additives, the stirring mechanism 2 can crush the material and stir the crushed material horizontally and vertically, thereby achieving comprehensive stirring of the material in the fermentation tank 1, and then fully mixing the material and the additive, so that the material and the additive are evenly distributed, thereby improving the fermentation effect of the material.

[0049] Since the additive is preferably a liquid bacterial agent, that is, the bacterial agent is diluted at a ratio of 1:50-1:100, the additive needs to be stirred and mixed to keep the concentration of the additive uniform.

[0050] The mixing assembly 36 includes: a fixed rod 362 fixedly mounted in the liquid storage tank 34; a circular tube 361 slidably mounted on the fixed rod 362, the top of the circular tube 361 being rotatably connected to the linkage frame 355; a linkage plate 365 fixedly mounted on the circular tube 361; an arc-shaped plate 366 fixedly mounted on the linkage plate 365; a rolling member 364 rotatably mounted in the circular tube 361; and a guide groove 363 provided on the fixed rod 362, the guide groove 363 being spirally shaped, and the rolling member 364 slidably mounted in the guide groove 363.

[0051] When the linkage frame 355 moves downward, it can drive the circular tube 361 to move downward and make the rolling element 364 move along the path of the guide groove 363. At this time, the circular tube 361 rotates. When the linkage frame 355 moves upward, it can drive the circular tube 361 to move upward and drive the rolling element 364 to move along the path of the guide groove 363. At this time, the circular tube 361 rotates in the opposite direction. Therefore, the up and down reciprocating movement of the linkage frame 355 can drive the circular tube 361 to move up and down while rotating.

[0052] The circular tube 361 drives the interlocking plate 365 and the arc plate 366 to move back and forth and rotate at the same time. The interlocking plate 365 moves back and forth and rotates at the same time, thereby realizing longitudinal stirring of the additive. The arc plate 366 moves back and forth and rotates at the same time, thereby realizing transverse stirring of the additive, thereby realizing uniform mixing of the additive, ensuring the uniformity of the additive concentration, avoiding uneven additive concentration, affecting the mixing with the material, and thus affecting the fermentation effect of the material.

[0053] In addition, the top and bottom of the linkage plate 365 are both arc-shaped. During the reciprocating movement of the linkage plate 365, the adhesion of the fluid is reduced, the shearing efficiency is improved, and the dispersion of the liquid is accelerated, thereby improving the stirring effect of the additive. The arc-shaped arrangement of the arc-shaped plate 366 can better drive the flow of the liquid, thereby further improving the stirring effect on the additive.

[0054] It is added here that the rolling element 364 is preferably a bull's eye ball.

[0055] By setting the spraying mechanism 3, the present invention can transport the additive in the liquid storage tank 34 to the nozzle 32 and spray it on the surface of the material while feeding the material. At the same time, the additive can be stirred horizontally and vertically, so as to achieve uniform mixing of the additive and ensure the uniformity of the additive concentration.

[0056] The vibration unit 274 includes: a fixed pipe 2744 fixedly mounted in the fermentation tank 1, in which hydraulic oil is stored; a piston 1 2743 slidably mounted in the fixed pipe 2744; a movable rod 2742 fixedly connected to the piston 1 2743, wherein the end of the movable rod 2742 away from the piston 1 2743 passes through the side wall of the fixed pipe 2744; a connecting rod 2741 hingedly mounted to the movable rod 2742, wherein the connecting rod 2741 and the nozzle 32 are hingedly arranged; a connecting pipe 2745 connected to the fixed pipe 2744, and a connecting pipe 2746 connected to the fixed pipe 2744. 745 is fixedly installed on the fixed plate, and the fixed tube 2744 and the connecting tube 2745 are connected through the liquid guide tube; the piston 2746 is slidably installed in the connecting tube 2745; the push rod 2747 is fixedly connected to the piston 2746, and the top end of the push rod 2747 passes through the side wall of the connecting tube 2745 and is fixedly connected to the collecting hopper 273; the reset spring 2748 is driven to reset the push rod 2747, and one end of the reset spring 2748 is fixedly connected to the piston 2746, and the other end is fixedly connected to the inner wall of the connecting tube 2745.

[0057] When the nozzle 32 swings, it can drive the connecting rod 2741 to move, the connecting rod 2741 drives the movable rod 2742 to move, and the movable rod 2742 drives the piston 1 2743 to move, so that the piston 1 2743 moves back and forth in the fixed tube 2744.

[0058] That is, when the nozzle 32 is expanded, piston 1 2743 squeezes the hydraulic oil in the fixed tube 2744, and the hydraulic oil enters the connecting tube 2745 through the liquid guide tube, and drives piston 2 2746 to move upward, piston 2 2746 drives the push rod 2747 to move upward, and the push rod 2747 drives the collecting hopper 273 to move upward and drives the reset spring 2748 to be compressed; when the nozzle 32 is retracted, piston 1 2743 is reset, and the hydraulic oil in the connecting tube 2745 can be sucked into the fixed tube 2744. At this time, the elastic force of the reset spring 2748 can drive the push rod 2747 to reset downward, thereby driving the collecting hopper 273 to move downward.

[0059] It can be seen from the above records that when the nozzle 32 swings, it can drive the connecting rod 2741 to move, the connecting rod 2741 drives the movable rod 2742 to move, and the movable rod 2742 drives the piston 1 2743 to move, so that the piston 1 2743 moves back and forth in the fixed tube 2744, thereby driving the push rod 2747 to move up and down, and the push rod 2747 drives the collecting hopper 273 to move up and down, thereby causing the collecting hopper 273 to vibrate, thereby improving the material feeding efficiency and avoiding the accumulation of materials in the feed hopper, which leads to the problem of blockage at the discharge end of the collecting hopper 273.

[0060] Support legs are fixedly mounted on the fermentation tank 1 , and universal wheels are fixedly mounted on the support legs.

[0061] A plurality of supporting legs are provided, so that the fermentation tank 1 can be supported more stably, ensuring the stability of the fermentation tank 1 when in use. The provision of universal wheels makes it easy to move the fermentation tank 1, thereby improving the convenience of using the fermentation tank 1.

[0062] It is added here that the universal wheel is preferably a locking universal wheel, so that after the fermenter 1 is moved to a desired position, the universal wheel can be locked to prevent the fermenter 1 from sliding, thereby improving the stability of the fermenter 1 during use.

[0063] The following steps are included: Step S1: adding a certain amount of material into the fermentation tank 1, the material is fully stirred by the operation of the stirring mechanism 2, and the additive is evenly sprayed into the material by the operation of the spraying mechanism 3; Step S2: The material and additives are mixed uniformly by the operation of the stirring mechanism 2; Step S3: After the fermentation is completed, the material is taken out.
