Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, and in particular to an environmentally friendly, low-emission livestock manure fermentation treatment device. Background Art

[0002] The livestock manure fermentation treatment device is designed based on the principle of microbial aerobic fermentation. It uses thermophilic microorganisms to decompose organic matter in manure under an aerobic environment and convert it into stable humus. Heat is released in the process to increase the temperature of the pile, which can kill harmful bacteria and parasite eggs. After the above-mentioned fermentation treatment, the manure can be made into organic fertilizer. The organic matter in it is decomposed into nutrients that are easily absorbed by plants, which can improve soil fertility and soil structure.

[0003] After the feces fermentation in the fermentation tank is completed, when it is necessary to discharge, first open the discharge port at the bottom of the tank body, and the feces in the tank body will be discharged along the discharge port under the action of gravity. The height of the feces inside the tank body will gradually decrease. In this process, the feces near the discharge port will be lower than the feces far away from the discharge port. At this time, the feces surface will be inclined. As the feces are gradually discharged, the feces at the bottom of the tank body far away from the discharge port will accumulate and cannot move to the discharge port. This will cause feces residue in the tank body. The residual feces will form a local anaerobic microenvironment at the bottom of the tank (local oxygen deficiency). If the residual feces continues to ferment at the bottom of the tank, excessive gas, such as methane, will be produced, resulting in increased pressure and safety hazards. Secondly, the residue will also become compacted, affecting the next discharge and even blocking the discharge port. Summary of the invention

[0023] Example 1: An environmentally friendly, low-emission livestock manure fermentation treatment device, please refer to Figure 1-Figure 4 and Fig. 9, including: a base 1, the base 1 is fixedly connected with a fermentation tank 2 and a discharge pipe 101, the fermentation tank 2 is provided with a first hole 201 and a motor 3, the output shaft of the motor 3 is fixedly connected with a main shaft 4 rotatably connected to the fermentation tank 2; a secondary shaft 5, which is arranged on the main shaft 4, and a one-way overrunning clutch 1 is connected between the two, and the main shaft 4 and the secondary shaft 5 are both provided with stirring blades 6 distributed at intervals; a fixed ring 7, which is fixedly connected to the secondary shaft 5, and the fixed ring 7 is provided with a driving ring 8, and the two are driven by a one-way overrunning clutch 2; a partition plate 9, which is rotatably connected to the base 1, and The partition plate 9 is sealed and rotatably connected with the secondary shaft 5, and a second hole 901 is provided on the partition plate 9. When the first hole 201 and the second hole 901 are aligned, the fermentation tank 2 is connected with the discharge pipe 101 through the first hole 201 and the second hole 901. A driving module for driving the partition plate 9 to rotate is provided in the base 1, and an air supply module 10 for replenishing air into the fermentation tank 2 is provided on the fermentation tank 2. The air supply module 10 is used to provide air to the fermentation tank 2 through the stirring blades 6; a monitoring mechanism is provided in the fermentation tank 2, and is used to monitor the height of the material in the fermentation tank 2.

[0024] In the above scheme, the problem of residual feces accumulating at the bottom of the fermentation tank during the discharge process of the existing feces fermentation tank is solved; the upper side of the fermentation tank 2 is provided with a feed port and an exhaust port, and the main shaft 4 and the stirring blade 6 are both provided with a gas passage, and the gas passages of the two are connected, and the air outlet of the air supply module 10 is connected with the gas passage of the main shaft 4, so that the stirring blade 6 sprays air into the feces during the stirring process of the feces, which is conducive to the fermentation of the feces in the fermentation tank 2 (this is the existing structure, not shown in the figure); the motor 3 only drives the main shaft 4 to rotate clockwise ( Figure 1 ), under the action of the one-way overrunning clutch 1 between the main shaft 4 and the secondary shaft 5, when the main shaft 4 actively rotates clockwise, it can drive the secondary shaft 5 to rotate synchronously, and when the secondary shaft 5 actively rotates clockwise, the main shaft 4 will not rotate; under the action of the one-way overrunning clutch 2 between the fixed ring 7 and the driving ring 8, when the driving ring 8 does not rotate, the fixed ring 7 can rotate clockwise, and when the driving ring 8 actively rotates clockwise, the driving ring 8 drives the fixed ring 7 to rotate synchronously clockwise; the one-way overrunning clutch 1 and the one-way overrunning clutch 2 are both existing structures, and their internal structures are not shown in the figure; the first hole 201 is aligned with the entrance on the right side of the discharge pipe 101 in the vertical direction.

[0025] Initially, the second hole 901 and the first hole 201 are in a staggered state, that is, the partition plate 9 blocks the first hole 201 and the discharge pipe 101 at the same time, and the partition plate 9 is driven to rotate by the driving module on the base 1, thereby controlling the connection state between the fermentation tank 2 and the discharge pipe 101; this scheme proposes a manual control state of the partition plate 9, such as Figure 2 and Figure 3As shown, the base 1 is rotatably connected with a rotating rod 21 and a transmission shaft 22, the rotating rod 21 and the transmission shaft 22 are driven by a gear set, and the transmission shaft 22 and the partition plate 9 are driven by a bevel gear set; this device is mostly used in livestock and poultry farms. When the device needs to discharge, if the voltage and current are unstable, the driving module on the base 1 cannot be started due to the voltage fluctuation, and the partition plate 9 cannot be rotated, and the discharge operation cannot be performed in time, resulting in excessive fermentation of feces in the fermentation tank 2, causing the pressure in the fermentation tank 2 to increase, and there is a safety hazard. At this time, the operator can manually rotate the rotating rod 21 to rotate the partition plate 9, and connect the fermentation tank 2 to the discharge pipe 101 through the first hole 201 and the second hole 901 to discharge the feces.

[0026] See also Figure 2 and Figure 5-Figure 7 The monitoring mechanism includes: a monitoring ring 31, which is slidably connected to the fermentation tank 2; a buoyancy plate 32, which is fixed to the lower side of the monitoring ring 31; a first roller 33, which is rotatably connected to the fermentation tank 2, and a first pull rope 34 is wound around the first roller 33, and one end of the first pull rope 34 is fixed to the monitoring ring 31; a transmission ring 35, which is rotatably connected to the base 1, and a torsion spring is provided between the transmission ring 35 and the driving ring 8; a driving assembly, which is arranged on the fermentation tank 2, and is used to drive the transmission ring 35 to rotate; a limiting assembly, which is arranged in the base 1, and is used to limit the driving ring 8.

[0027] In the above scheme, a method for monitoring the height of feces in the fermentation tank 2 is proposed; the monitoring ring 31 is a counterweight ring, so that it can move according to the height of the feces, and the buoyancy plate 32 is used to increase its contact area with the feces, reduce the squeezing force on the upper side of the feces, and reduce the probability of the feces being compacted; the upper part of the fermentation tank 2 is slidably connected with a U-shaped plate, and the U-shaped plate of the fermentation tank 2 is used to limit the buoyancy plate 32. Initially, the buoyancy plate 32 is located at the upper part of the fermentation tank 2 and does not contact the feces; the diameters of the monitoring ring 31 and the buoyancy plate 32 are both smaller than the inner diameter of the fermentation tank 2.

[0028] See also Figure 2 and Figure 5-Figure 7 The driving assembly includes: a first shell 41, which is fixedly connected to the fermentation tank 2. A bracket is provided on the left side of the fermentation tank 2. The bracket of the fermentation tank 2 is fixedly connected to the first shell 41.

The first piston column 42 is fixedly connected to the other end of the first pull rope 34; a first push rod 43, which is fixedly connected to the base 1. The first push rod 43 is filled with hydraulic oil. The first shell 41 is connected to the fixed part of the first push rod 43 through the first tube 411. The telescopic end of the first push rod 43 and the transmission ring 35 are driven by a gear rack.

[0029] See also Figure 5-Figure 7The limiting assembly includes: a first elastic push rod 51, which is fixed to the first shell 41, and the telescopic end of the first elastic push rod 51 is slidably connected to the first shell 41, and the first piston column 42 is used to squeeze the telescopic end of the first elastic push rod 51; a second push rod 53, which is fixed to the base 1, and the first elastic push rod 51 is connected to the second push rod 53 through the second tube 52, and the telescopic end of the second push rod 53 is used to limit the drive ring 8.

[0030] In the above scheme, the first elastic push rod 51 is located at the upper part of the first shell 41; the telescopic end of the first elastic push rod 51 passes through one side of the first shell 41, and the upper side of the first piston column 42 is set as an annular inclined surface; a limiting hole is set on the driving ring 8, and the telescopic end of the second push rod 53 is inserted into the limiting hole of the driving ring 8, and the driving ring 8 cannot rotate; the second push rod 53 is filled with hydraulic oil, and when the telescopic end of the first elastic push rod 51 retracts, the first elastic push rod 51 extracts the hydraulic oil in the second push rod 53 through the second tube 52.

[0031] Workflow: When using the device to ferment feces, first inject the feces raw material into the fermentation tank 2 from the feed port of the fermentation tank 2 until the feces reaches a specified height (lower than the buoyancy plate 32), stop injecting, and block the feed port and the air outlet of the fermentation tank 2 to make the interior of the fermentation tank 2 in a sealed state, and then start to ferment the feces. During the fermentation process, start the motor 3 and the air supply module 10 at a set time interval, and the output shaft of the motor 3 drives the main shaft 4 to rotate clockwise. The main shaft 4 drives the secondary shaft 5 to rotate clockwise through the one-way overrunning clutch. The main shaft 4 and the secondary shaft 5 respectively drive the stirring blades 6 thereon to rotate clockwise, so as to stir the feces and make the feces fully fermented. At the same time, the air supply module 10 pumps the outside air into the gas passage of the main shaft 4, and then the gas enters the gas passage of the stirring blade 6 and is discharged into the fermentation tank 2, so as to accelerate the fermentation rate. During this process, the gas outlet is exhausted to the outside at a regular time, and the discharged gas is filtered by the existing filtering device.

[0032] After the feces fermentation is completed, when the feces needs to be discharged, the operator drives the partition plate 9 to rotate through the driving module on the base 1. When the second hole 901 is aligned with the first hole 201, the first hole 201 is connected to the discharge pipe 101. At this time, the feces in the fermentation tank 2 begins to move downward under the action of gravity, and the operator transfers the feces flowing out of the discharge pipe 101.

[0033] As the feces are slowly discharged, the feces near the first hole 201 (left side) moves downward first, and the feces away from the first hole 201 (right side) moves toward the first hole 201. During this process, the height of the feces forms a slope with higher right and lower left.

[0034] If discharge is required, the voltage of the device is unstable and the driving module on the base 1 cannot work normally. At this time, the operator pulls out the U-shaped plate of the fermentation tank 2 to release the limit on the buoyancy plate 32. Then the monitoring ring 31 moves downward under the action of gravity and drives the buoyancy plate 32 to move synchronously. The monitoring ring 31 slides downward along the fermentation tank 2. The monitoring ring 31 pulls the first pull rope 34, and the right end of the first pull rope 34 moves downward. The first roller 33 starts to rotate, and the first roller 33 reels the left end of the first pull rope 34. The left end of the first pull rope 34 drives the first piston column 42 to move upward until the buoyancy plate 32 is completely in contact with the feces. The buoyancy plate 32 moves downward as the surface of the feces drops. As the feces are discharged, the buoyancy plate 32 gradually tilts (low on the left and high on the right).

[0035] During the downward movement of the buoyancy plate 32, the first piston column 42 moves upward, and the first shell 41 draws out the hydraulic oil in the first push rod 43 through the first tube 411. The telescopic end of the first push rod 43 begins to retract, and the telescopic end of the first push rod 43 drives the transmission ring 35 to rotate clockwise through the gear rack. At this time, the telescopic end of the second push rod 53 limits the drive ring 8, so that the torsion spring between the transmission ring 35 and the drive ring 8 accumulates force.

[0036] When the first piston column 42 contacts the telescopic end of the first elastic push rod 51, the feces is about to be discharged. At this time, the buoyancy plate 32 continues to move downward, that is, the first piston column 42 moves upward and squeezes the telescopic end of the first elastic push rod 51 (the first elastic push rod 51 is compressed and stored), and the first elastic push rod 51 extracts the hydraulic oil in the second push rod 53 through the second tube 52. After the round table surface of the first piston column 42 loses contact with the telescopic end of the first elastic push rod 51, the telescopic end of the second push rod 53 loses contact with the drive ring 8, the drive ring 8 loses its limit, and the drive ring 8 starts to rotate clockwise under the action of the torsion spring. The driving ring 8 drives the fixing ring 7 to rotate clockwise through the one-way overrunning clutch 2, and the fixing ring 7 drives the secondary shaft 5 to rotate clockwise. The secondary shaft 5 rotates relative to the main shaft 4, thereby reducing the resistance to the rotation of the secondary shaft 5 and reducing the probability of damage to the motor 3. The secondary shaft 5 drives the stirring blade 6 thereon to rotate, so that the stirring blade 6 stirs the feces, the feces begins to flow and the height tends to be horizontal, thereby reducing the accumulation of feces on the right side. As the height of the feces tends to be horizontal, that is, the feces on the right side gradually moves to the left side and is discharged through the first hole 201 and the discharge pipe 101, the buoyancy plate 32 gradually tends to be horizontal.

[0037] During the stirring process of the stirring blade 6 on the secondary shaft 5, the feces accumulated on the right side are gradually discharged, and the buoyancy plate 32 continues to move slowly downward until the feces in the fermentation tank 2 is discharged, the buoyancy plate 32 contacts the bottom of the fermentation tank 2, the buoyancy plate 32 stops moving, the telescopic end of the first push rod 43 stops retracting, that is, the transmission ring 35 stops rotating, the first piston column 42 stops rotating, and during this process, the first piston column 42 and the telescopic end of the first elastic push rod 51 are always in contact. After the feces are discharged, the first roller 33 is rotated in the opposite direction, the first pull rope 34 pulls the monitoring ring 31 upward and resets it, and the U-shaped plate is inserted into the fermentation tank 2, thereby limiting the monitoring ring 31. During this process, the operator resets the telescopic end of the first push rod 43, the first piston column 42 is reset synchronously, and the telescopic end of the second push rod 53 is re-limited to the drive ring 8, the first elastic push rod 51 is reset under the action of its own elasticity, and then the device is stopped, and the fermentation tank 2 is repeatedly cleaned for subsequent use.

[0039] In the above scheme, the secondary shaft 5 is provided with an air outlet, which is located at the lower part of the moving part 63, and the air outlet is connected to the air cavity 501, so that the moving part 63 can move up and down; the scraper 64 is used to scrape off the feces adhered to the bottom of the fermentation tank 2, further reducing the residual feces in the fermentation tank 2; the moving part 63 is composed of a horizontal plate, a round rod and a circular plate, the circular plate is sealed and slidably connected to the secondary shaft 5, the horizontal plate is fixed to the scraper 64, and is sealed and slidably connected to the secondary shaft 5.

The stirring shell 65 is connected to the air cavity 501, and a one-way valve is installed in the second through hole on the stirring shell 65.

[0044] See also Fig.11 and Fig.12The regulating component includes: a third push rod 74, which is fixed to the air guide pipe 62, and the third push rod 74 is filled with hydraulic oil. The telescopic end of the third push rod 74 is used to limit the blocking plate 82. A slot is provided on the side of the blocking plate 82 close to the third through hole. Initially, the telescopic end of the third push rod 74 is located in the slot of the blocking plate 82; a second elastic push rod 76, which is fixed to the second shell 73, and its telescopic end is slidably connected to the second shell 73. The structure of the second piston column 75 is consistent with that of the first piston column 42. The second piston column 75 is used to squeeze the telescopic end of the second elastic push rod 76. The second elastic push rod 76 is connected to the third push rod 74 through the third tube 741. When the telescopic end of the second elastic push rod 76 retracts, the second elastic push rod 76 extracts the hydraulic oil in the third push rod 74 through the third tube 741.

[0045] Working process: During the process of feces fermentation, when the air supply module 10 is working, the air supply module 10 inflates the air storage box 61, and the value of the pressure detector in the air storage box 61 gradually increases until it reaches a specified value (higher than normal pressure). The electric control valve on the air storage box 61 is closed, and the air supply module 10 stops inflating the air storage box 61.

[0046] During the downward movement of the monitoring ring 31, the monitoring ring 31 pulls the left end of the second pull rope 72 to move downward, the second pull rope 72 drives the second roller 71 to rotate, the second roller 71 reels the right end of the second pull rope 72, and the right end of the second pull rope 72 drives the second piston column 75 to move upward. Since the monitoring ring 31 is in an inclined state during the downward movement, the position of the second piston column 75 is lower than that of the first piston column 42.

[0047] During the process of the first piston column 42 and the telescopic end of the first elastic push rod 51 being fitted and moving relative to each other, the monitoring ring 31 gradually tends to a horizontal state, that is, the right side of the monitoring ring 31 moves downward, and the second piston column 75 continues to move upward until the monitoring ring 31 is horizontal, and the second piston column 75 contacts the telescopic end of the second elastic push rod 76. As the monitoring ring 31 moves horizontally downward, the second piston column 75 squeezes the telescopic end of the second elastic push rod 76 (the second elastic push rod 76 is compressed and accumulates force), and the second elastic push rod 76 extracts the hydraulic oil in the third push rod 74 through the third tube 741. The telescopic end of the third push rod 74 retracts and loses contact with the sealing plate 82. The sealing plate 82 slides along the mounting shell 81 under the action of the tension spring thereon, and the third through hole of the sealing plate 82 is connected to the air duct 62, thereby releasing the blockage of the air duct 62.

[0048] After the blockage of the air guide pipe 62 is released, the gas in the air storage box 61 enters the air chamber 501 through the air guide pipe 62. The gas pressure in the air chamber 501 increases, and the gas pushes the moving member 63 downward and compresses the spring on the moving member 63. The moving member 63 drives the scraper 64 on it to move downward. The scraper 64 slides relative to the stirring shell 65, and the scraper 64 protrudes out of the stirring shell 65. During the downward movement of the scraper 64, Gradually contact with the bottom of the fermentation tank 2. During this process, the secondary shaft 5 drives the stirring blade 6 thereon to rotate clockwise, the secondary shaft 5 drives the stirring shell 65 thereon to rotate, the stirring shell 65 drives the scraper 64 to rotate, the scraper 64 pushes the feces at the bottom of the fermentation tank 2, makes the feces at the bottom of the fermentation tank 2 flow, and scrapes off the feces adhered to the bottom of the fermentation tank 2, further increases the discharge amount of feces, reduces the residual feces in the fermentation tank 2, and ensures the cleanliness of the fermentation tank 2. During this process, the scraper 64 pushes the material through the first hole 201 to accelerate the discharge of feces.

[0049] During the downward movement of the scraper 64, the gap between the upper side of the scraper 64 and the stirring shell 65 increases ( Fig.10 As shown), during this process, the gas in the air cavity 501 flows upward and passes through the first through hole of the moving member 63, and the gas then enters the stirring shell 65 through the sliding part of the moving member 63 and the secondary shaft 5. The gas in the stirring shell 65 is discharged upward through the one-way valve thereon, and the gas discharged from the stirring shell 65 enters the fermentation tank 2, thereby diluting the irritating gas in the fermentation tank 2 and reducing the harmfulness of the irritating gas discharge. During the gas discharge process, the stirring shell 65 rotates to make the gas move upward in a spiral state, thereby increasing the range covered by the discharged gas and ensuring that the discharged gas and the irritating gas are fully integrated. By discharging gas into the fermentation tank 2, the pressure in the fermentation tank 2 is increased, the fluidity of feces is improved, the discharge of feces in the fermentation tank 2 is facilitated, and the speed of feces discharge is accelerated.

[0050] After the gas pressure in the gas storage box 61 is restored, the moving member 63 loses the gas pressure, and the moving member 63 moves upward under the action of the spring thereon, and drives the scraper 64 to move upward synchronously and lose contact with the fermentation tank 2. The position of the scraper 64 is adjusted according to the storage amount of feces in the fermentation tank 2, that is, the scraper 64 is brought into contact with the fermentation tank 2 only when the feces is about to be discharged, so as to avoid the scraper 64 always being in contact with the fermentation tank 2 and causing aggravated wear between the two.

[0051] After the feces are discharged, when the first roller 33 is rotated in the opposite direction, the second roller 71 is rotated in the opposite direction synchronously, and the second pull rope 72 and the first pull rope 34 jointly drive the monitoring ring 31 to move upward, and the second piston column 75 moves downward and resets under the action of gravity, and the second elastic push rod 76 resets under the action of its own elasticity, and then the operator controls the sealing plate 82 to reset, so that the telescopic end of the third push rod 74 is inserted into the sealing plate 82 again. After resetting all parts, the operator stops using the device.
