Description

Technical Field

[0001] This invention belongs to the technical field of amino acid fermentation production equipment, specifically relating to a fermenter feeding device and its usage method for amino acid production. Background Technology

[0002] In recent years, the amino acid fermentation industry has developed rapidly. As the core production equipment, the stability of the fermenter's feeding system directly affects the product yield and purity.

[0003] Currently, the fermentation tank feeding devices commonly used in the industry are mostly composed of a lifting mechanism, a hopper, and a material discharge control component. The lifting device transports the material to the fermentation tank inlet, and the material is discharged by the weight of the hopper or mechanical drive. However, the existing devices have prominent problems with material adhering to the wall in practical applications, especially when processing wet materials. The material is easy to stick to the inner wall of the hopper, resulting in material waste and affecting the purity of subsequent feed. At the same time, the wall adhesion characteristics of dry and wet materials are quite different. Wet materials are prone to clumping and residue, while dry materials may cause splashing pollution.

A central shaft is fixedly disposed through the middle of the second spur gear. A cam is fixedly disposed through the upper part of the central shaft. The cam is used to repeatedly rotate the vibrating hammer, thereby realizing the continuous striking of the hopper by the vibrating hammer.

[0007] As a preferred embodiment of the feeding device for a fermenter used in amino acid production according to the present invention, the lifting mechanism includes an L-shaped outer plate fixedly disposed inside the lower frame, an L-shaped inner plate inserted into the upper part of the L-shaped outer plate, the upper part of the L-shaped inner plate being fixedly connected to the bottom opening of the hopper, and the lower surface of the L-shaped outer plate abutting and sealingly sealing the upper surface of the material drop plate.

[0008] As a preferred embodiment of the fermenter feeding device for amino acid production of the present invention, a top plate is fixedly installed on the side of the L-shaped inner plate located on the vibrating hammer, and the lower surface of the top plate away from the L-shaped inner plate is fixedly connected to the upper surface of the central shaft.

[0009] As a preferred embodiment of the fermenter feeding device for amino acid production according to the present invention, a third spur gear is provided at the lower part of the second spur gear, the third spur gear is fixedly and continuously connected to the central shaft, and the central shaft has more teeth than the third spur gear.

[0010] As a preferred embodiment of the fermenter feeding device for amino acid production according to the present invention, the lifting mechanism further includes a plurality of elastic telescopic rods fixedly disposed between the upper frame and the lower frame, and the plurality of elastic telescopic rods are used to push the hopper to achieve lifting and lowering.

[0011] As a preferred embodiment of the fermenter feeding device for amino acid production of the present invention, the stretching assembly includes a movable block rotatably disposed in the middle of the movable seat, an outer ring fixedly disposed in the middle of the surface of the movable block away from the movable seat, a first panel slidably disposed in the inner cavity of the outer ring, a compression spring elastically connected to the surface of the first panel away from the movable seat, and a second panel elastically connected to the other end of the compression spring.

[0012] As a preferred embodiment of the fermenter feeding device for amino acid production of the present invention, an outer sleeve is provided on the outside of the second panel. The outer sleeve movably passes through the upper part of the central shaft. A fixed back plate is fixedly provided at the end of the outer sleeve away from the movable seat. The fixed back plate is fixedly connected to the L-shaped outer plate. A pull rope is provided in the inner cavity of the outer sleeve. One end of the pull rope movably passes through the second panel and the middle of the compression spring and is fixedly connected to the middle surface of the first panel. The other end of the pull rope is fixedly connected to the middle of the lower surface of the top plate away from the vibrating hammer.

[0013] As a preferred embodiment of the fermenter feeding device for amino acid production according to the present invention, the stretching assembly further includes a vertical groove formed on the upper part of the central shaft, the length of which is greater than the width of the first spur gear.

[0014] A method of use, applied to the above-mentioned feeder device for fermenters used in amino acid production, includes: S1. The lifting device lifts the hopper loaded with materials to the feed inlet of the fermentation tank to complete the feeding preparation; S2. Start the motor to drive the transmission shaft to rotate, which will cause the material discharge plate to flip and open the discharge port, allowing the material to fall into the fermentation tank. At the same time, the meshing transmission of the face gear, the first spur gear, and the second spur gear will drive the central shaft and cam to rotate. S3. The cam rotates periodically to push the vibrating hammer, and with the reset action of the torsion spring or compression spring, the vibrating hammer repeatedly flips and strikes the inner wall of the hopper, shaking off the material hanging on the wall. S4. Depending on the dryness of the material, the relative sliding of the L-shaped outer plate and the L-shaped inner plate, and the extension and retraction of the elastic telescopic rod drive the top plate to rise and fall, thereby switching the meshing state of the second or third spur gear with the first spur gear, changing the rotation speed of the central shaft, and realizing the adjustment of the striking frequency of the vibratory hammer. S5. The lifting and lowering of the top plate synchronously pulls the rope, which compresses or releases the compression spring through the first panel, changing the tension of the compression spring and thus adjusting the striking force of the vibratory hammer.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the coordinated action of the vibrating hammer and the transmission component in the striking mechanism, the transmission component drives the vibrating hammer to continuously strike the inner wall of the hopper, shaking off the wall-mounted material adhering to the inner wall of the hopper. This effectively solves the problem of material waste caused by material adhering to the wall in existing devices, while also preventing residual material from affecting the purity of subsequent feed.

[0016] 2. By cooperating the lifting mechanism of the frequency adjustment mechanism and the tensioning component of the force adjustment mechanism, the frequency and force of the vibratory hammer are adaptively changed according to the difference in wall adhesion characteristics of dry and wet materials. When the material is wet, the high frequency and strong force are maintained to deal with the agglomeration residue, while when the material is dry, the low frequency and weak force are switched to prevent splashing and contamination. This solves the feeding problem caused by the different wall adhesion characteristics of dry and wet materials. Attached Figure Description

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figure 1 - Figure 7 This is the first embodiment of the present invention. This embodiment provides a feeding device for a fermenter for amino acid production, which achieves the effects of material splashing causing contamination and reducing material adhering to the wall. It includes a knocking mechanism, which includes a fermenter body 10. A lifting device 11 is provided on one side of the fermenter body 10. A hopper 12 is provided on the lifting device 11. A dropping plate 13 is provided at the lower part of the hopper 12. A lower frame 14 is provided on the outer side of the dropping plate 13. A vibrating hammer 15 is provided on the lower frame 14. A transmission component 16 is provided on one side of the vibrating hammer 15. The transmission component 16 is used to drive the vibrating hammer 15 to knock off the material adhering to the inner wall of the hopper 12. The frequency adjustment mechanism includes an upper frame 20 fixedly installed on the upper part of the hopper 12, and a lifting mechanism 21 installed at the lower part of the upper frame 20. The lifting mechanism 21 is used to change the striking frequency of the vibrating hammer 15 on the hopper 12 according to the different dry and wet materials. The force adjustment mechanism includes a movable seat 30 fixedly mounted on the vibrating hammer 15. A tensioning component 31 is provided on one side of the movable seat 30. The tensioning component 31 is used to change the striking force of the vibrating hammer 15 on the hopper 12.

[0023] Specifically, the lifting device 11 drives the hopper 12 to feed the fermentation tank 10. Since the fermentation tank 10 and the lifting device 11 are existing technologies, their structural principles will not be elaborated here. When the material in the hopper 12 is unloaded, the transmission component 16 controls the opening and closing of the discharge plate 13, thereby causing the material to fall out. At the same time, the transmission component 16 pushes the vibrating hammer 15 to rotate intermittently. The intermittent rotation of the vibrating hammer 15 will continuously strike the hopper 12, thereby causing the material adhering to the inner wall of the hopper 12 to fall off under the vibration of the vibrating hammer 15. The lifting mechanism 21 is used to control the striking frequency of the vibrating hammer 15 according to the different dryness and moisture of the material, so that different wall-mounted materials can be separated from the inner wall of the hopper 12 as much as possible. The stretching component 31 can control the striking force of the vibrating hammer 15 according to the different dryness and moisture of the material, so that the wet material can be shaken down better.

[0024] Furthermore, the transmission assembly 16 includes a transmission shaft 161 rotatably mounted on one side of the discharge plate 13. One end of the transmission shaft 161 is fixedly connected to a motor 162. A face gear 163 is fixedly passed through the middle of the transmission shaft 161. A first spur gear 164 is meshed at the lower end of the face gear 163. A second spur gear 165 is meshed on one side of the first spur gear 164. A central shaft 166 is fixedly passed through the middle of the second spur gear 165. A cam 167 is fixedly passed through the upper part of the central shaft 166. The cam 167 is used to repeatedly rotate the vibrating hammer 15, thereby realizing the continuous striking of the hopper 12 by the vibrating hammer 15.

[0025] Movable seats are provided at both ends of the drive shaft 161. These seats are fixedly connected to the lower frame 14 and the discharge plate 13, respectively. The seat fixed to the discharge plate 13 is fixedly connected to the drive shaft 161, while the seat fixed to the lower frame 14 is movably connected to the drive shaft 161. When the output end of the motor 162 drives the drive shaft 161 to rotate, the drive shaft 161 can rotate around the seat fixed to the lower frame 14, thereby causing the discharge plate 13 to flip and open the discharge port. It should be noted that the lower end of the vibrating hammer 15 is connected to the inner wall of the lower frame 14 through a fixed round rod, and the vibrating hammer 15 itself is connected to the fixed round rod for rotation limit. A torsion spring is provided at the connection, so that the vibrating hammer 15 abuts against the side wall of the hopper 12 in the normal state. When the vibrating hammer 15 flips, it can be reset under the action of the torsion spring, thereby achieving the effect of repeated hammering.

[0026] In use, the hopper 12, loaded with the material to be fermented, is lifted to the inlet position of the fermentation tank 10 by the lifting device 11. After the hopper 12 is in place, the motor 162 starts, and its output drives the transmission shaft 161 to start rotating. Since the transmission shaft 161 is fixedly connected to the discharge plate 13, its rotation will cause the discharge plate 13 to rotate around its connection point with the lower frame 14, thereby opening the discharge port of the hopper 12 and allowing the internal material to fall into the fermentation tank 10.

[0027] Simultaneously, as the drive shaft 161 rotates, the face gear 163 fixed to it also rotates. This face gear 163 meshes with the first spur gear 164 below, thereby driving the first spur gear 164 to rotate. The first spur gear 164 then meshes with the second spur gear 165 on one side, transmitting power to the second spur gear 165. This power, through the central shaft 166 fixedly passing through the second spur gear 165, drives the cam 167 fixed to it to rotate.

[0028] When the cam 167 rotates, its protruding part periodically pushes the vibratory hammer 15. Since the lower end of the vibratory hammer 15 is connected to the lower frame 14 via a fixed round rod, and a torsion spring is provided at the connection point, the vibratory hammer 15, under the push of the cam 167, overcomes the elastic force of the torsion spring and rotates around the fixed round rod. After the protruding part of the cam 167 passes the vibratory hammer 15, the vibratory hammer 15 quickly swings back under the restoring action of the torsion spring, and its free end strikes the side wall of the hopper 12. The continuous rotation of the cam 167 causes the vibratory hammer 15 to repeatedly be pushed up and swing back to strike, thus creating a continuous and regular vibration on the hopper 12.

[0029] The impact force generated by this continuous rapping can effectively shake off the material adhering to the inner wall of the hopper 12, preventing it from sticking to the wall for a long time and ensuring that the material can smoothly and completely enter the fermentation tank 10.

[0030] Example 2 Reference Figure 2 - Figure 7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a frequency and force adjustment mechanism for the feeding device of a fermenter for amino acid production. This solves the problem of material clumping on the inner wall of the hopper 12 due to differences in dry and wet materials, which can affect product consistency. It includes a lifting mechanism 21 comprising an L-shaped outer plate 211 fixedly installed inside the lower frame 14. An L-shaped inner plate 212 is inserted into the upper part of the L-shaped outer plate 211. The upper part of the L-shaped inner plate 212 is fixedly connected to the opening at the bottom of the hopper 12, and the lower surface of the L-shaped outer plate 211 abuts against the upper surface of the discharge plate 13. The L-shaped inner plate 212 is fixedly provided with a top plate 213 on one side of the vibrating hammer 15. The lower surface of the top plate 213 away from the L-shaped inner plate 212 is fixedly connected to the upper surface of the central shaft 166. A third spur gear 214 is provided at the lower part of the second spur gear 165. The third spur gear 214 is fixedly and continuously connected to the central shaft 166, and the central shaft 166 has more teeth than the third spur gear 214. The lifting mechanism 21 also includes several elastic telescopic rods 215 fixedly provided between the upper frame 20 and the lower frame 14. The elastic telescopic rods 215 are used to push the hopper 12 to achieve lifting.

[0031] Specifically, the L-shaped outer plate 211 and L-shaped inner plate 212 separate the hopper 12 from the discharge plate 13, while the elastic telescopic rod 215 supports the hopper 12. Preferably, four elastic telescopic rods 215 are used in this device, positioned at the four corners of the upper frame 20 and the lower frame 14. As the hopper 12 is loaded with material, it presses down on the elastic telescopic rod 215 and the L-shaped inner plate 212. The L-shaped inner plate 212 slides within the L-shaped outer plate 211. During the descent of the hopper 12, the top plate 213 pushes the central shaft 166 downwards, causing the second spur gear 165 and the third spur gear 214 to mesh with the first spur gear 164. Conversely, after the hopper 12 discharges material, the weight of the material adhering to its inner wall varies depending on whether the material is dry or wet. Therefore, the elastic telescopic rod 215 pushes the hopper 12 to reset at different heights. Lighter materials can push the hopper 12 to fully reset, thus allowing the second spur gear 165 to revert to its original position. The second spur gear 165 disengages from the first spur gear 164, causing the first spur gear 164 to rotate synchronously, which in turn drives the third spur gear 214 to rotate synchronously. Because the third spur gear 214 has fewer teeth than the second spur gear 165, the rotation speed of the central shaft 166 and the cam 167 decreases, and the number of times the vibrating hammer 15 is pushed to rotate also decreases. The remaining wet material clinging to the wall cannot push the hopper 12 to fully reset, which also prevents the second spur gear 165 from disengaging from the first spur gear 164. Since the second spur gear 165 and the first spur gear 164 are in a meshing state at this time, and the number of teeth of the first spur gear 164 is greater than the number of teeth of the third spur gear 214, the rotation frequency of the central shaft 166 and the cam 167 remains unchanged, which will be higher than the rotation frequency when the third spur gear 214 and the first spur gear 164 are meshing, thereby increasing the striking frequency of the vibrating hammer 15.

[0032] Furthermore, the tensioning assembly 31 includes a movable block 311 rotatably disposed in the middle of the movable seat 30. An outer ring 312 is fixedly disposed in the middle of the surface of the movable block 311 away from the movable seat 30. A first panel 313 is slidably disposed in the inner cavity of the outer ring 312. A compression spring 314 is elastically connected to the surface of the first panel 313 away from the movable seat 30. A second panel 315 is elastically connected to the other end of the compression spring 314. An outer sleeve 316 is sleeved on the outside of the second panel 315. The outer sleeve 316 movably passes through the upper part of the central shaft 166. The outer sleeve 316 is located away from the movable seat 30. A fixed back plate 317 is fixedly installed at one end of the seat 30. The fixed back plate 317 is fixedly connected to the L-shaped outer plate 211. A pull rope 318 is installed in the inner cavity of the outer sleeve 316. One end of the pull rope 318 passes through the middle of the second panel 315 and the compression spring 314 and is fixedly connected to the middle surface of the first panel 313. The other end of the pull rope 318 is fixedly connected to the middle of the lower surface of the top plate 213 away from the vibrating hammer 15. The tensioning assembly 31 also includes a vertical slide groove 319 opened on the upper part of the central shaft 166. The length of the vertical slide groove 319 is greater than the width of the first spur gear 164.

[0033] The compression spring 314 can replace the torsion spring in the vibratory hammer 15. The upward movement of the top plate 213 pulls the pull rope 318 to tighten the compression spring 314, which can compress the tension of the compression spring 314. This increases the force of the compression spring 314 when it drives the vibratory hammer 15 to strike the hopper 12, thus allowing different striking forces to be changed according to the different moisture content of the materials. The vertical slide 319 ensures that the outer sleeve 316 does not affect the lifting and lowering of the central shaft 166.

[0034] In use, firstly, the hopper 12 containing the material to be fermented is lifted to the feed inlet of the fermentation tank 10 by the lifting device 11. Under the action of the material's gravity, the hopper 12 compresses the elastic telescopic rods 215 at the four corners, causing the L-shaped inner plate 212 to slide down along the inner cavity of the L-shaped outer plate 211. At this time, the top plate 213 on one side of the L-shaped inner plate 212 moves down synchronously, pushing the central shaft rod 166 to move down synchronously, so that the second spur gear 165 and the first spur gear 164 remain in mesh. At this time, the pull rope 318 is in a slack state, and the compression spring 314 in the outer ring 312 maintains the initial tension.

[0035] After the hopper 12 is in place, the motor 162 starts, and its output drives the transmission shaft 161 to rotate. On one hand, this causes the material discharge plate 13 to rotate around the connection point of the lower frame 14, opening the discharge port to allow the material to fall. On the other hand, the face gear 163 on the transmission shaft 161 drives the meshing first spur gear 164 to rotate. The first spur gear 164 further drives the second spur gear 165 to rotate, transmitting power through the central shaft 166 to make the cam 167 rotate continuously. The protruding part of the cam 167 periodically pushes the vibrating hammer 15, causing the vibrating hammer 15 to rotate around the fixed round rod against the elastic force of the compression spring 314. When the protruding part of the cam 167 disengages, the vibrating hammer 15 swings back under the reset action of the compression spring 314, striking the side wall of the hopper 12 to achieve the vibrating operation.

[0036] As the material continues to fall, its weight gradually decreases within the hopper 12. The rebound force of the elastic telescopic rod 215 pushes the hopper 12 upwards. If the material is wet, its adhesion to the wall is strong, and the weight of the remaining material is relatively large. The upward height of the hopper 12 is limited, and the L-shaped inner plate 212 cannot completely move the top plate 213 upwards. The central shaft 166 remains in a low position, and the second spur gear 165 is still meshed with the first spur gear 164. Since the second spur gear 165 has more teeth than the third spur gear 214, when the first spur gear 164 drives the second spur gear 165 to rotate, the central shaft 166 and the cam 167 maintain a high rotational speed, and the rapping hammer 15 maintains a high-frequency striking frequency, ensuring that the wet material adheres to the wall and falls off.

[0037] If the material is dry, its adhesion to the wall is weak, and the weight of the residual material is small. The elastic telescopic rod 215 pushes the hopper 12 to fully reset, and the L-shaped inner plate 212 drives the top plate 213 to move upward to its limit position. The central shaft rod 166 moves upward simultaneously, causing the second spur gear 165 to disengage from the first spur gear 164, and the third spur gear 214 to mesh with the first spur gear 164. Since the third spur gear 214 has fewer teeth than the second spur gear 165, when the first spur gear 164 drives the third spur gear 214 to rotate, the rotation speed of the central shaft rod 166 and the cam 167 decreases, and the striking frequency of the vibrating hammer 15 switches to a low frequency to avoid excessive vibration of the dry material causing splashing pollution.

[0038] As the frequency is adjusted, the hopper 12 rises, causing the top plate 213 to move upwards. The pull rope 318 is gradually tightened, pulling the first panel 313 to slide along the inner cavity of the outer ring 312. The compression spring 314, under pressure, experiences increased tension. For wet materials, the hopper 12 rises to a limited height, the pull rope 318 tightens less, the compression spring 314 has greater tension, and the vibratory hammer 15 swings back with increased striking force, meeting the strong adhesion requirements of wet materials. For dry materials, the hopper 12 fully resets, maximizing the tightening of the pull rope 318, providing moderate tension to the compression spring 314, and reducing the striking force of the vibratory hammer 15, ensuring dry material falls off while preventing material splashing.

[0039] Throughout the entire operation, the L-shaped outer plate 211 and the L-shaped inner plate 212 maintain a sealed contact to prevent material leakage; the vertical slide 319 ensures that the outer sleeve 316 does not interfere when the central shaft 166 is raised or lowered; the fixed connection between the pull rope 318 and the fixed back plate 317 ensures the stability of the force adjustment, and finally realizes the adaptive adjustment of the tapping frequency and force according to the dryness and moisture of the material, which solves the problem of wall adhesion and avoids pollution.

[0040] Example 3 Referring to Figure 1-2, this is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method of use for a fermenter feeding device applied to amino acid production, which includes... S1. The lifting device 11 stably lifts the hopper 12 loaded with the material to be fermented to the corresponding position of the feed inlet of the fermentation tank 10, completing the positioning preparation before feeding. S2. Start motor 162, whose output drives transmission shaft 161 to rotate. On the one hand, it drives the material drop plate 13 to rotate around the connection point of the lower frame 14, opening the discharge port of hopper 12, so that the internal material falls smoothly into fermentation tank 10. On the other hand, the face gear 163 on transmission shaft 161 meshes with the first spur gear 164, and the first spur gear 164 meshes with the second spur gear 165, thereby driving the central shaft 166 and the cam 167 fixed on it to rotate synchronously. S3. During the rotation of cam 167, its protruding part periodically pushes the vibrating hammer 15. The vibrating hammer 15 rotates around the fixed round rod on the lower frame 14 and stores force. When the protruding part of cam 167 disengages, under the reset action of torsion spring or compression spring 314, the vibrating hammer 15 quickly swings back to strike the inner wall of hopper 12, continuously shaking off the material hanging on the wall. S4. Due to differences in the dryness and moisture content of the material, the weight of the residual material in the hopper 12 varies, causing the elastic telescopic rod 215 to extend and retract to different degrees. This causes the L-shaped inner plate 212 to slide relative to the L-shaped outer plate 211, thereby pushing the top plate 213 and the central shaft 166 to rise and fall. When the material is wet, the residual weight is large, the central shaft 166 remains in a low position, the second spur gear 165 and the first spur gear 164 continue to mesh, the central shaft 166 maintains a high-frequency rotation speed, and the vibrating hammer 15 strikes at a high frequency. When the material is dry, the residual weight is small, the elastic telescopic rod 215 pushes the hopper 12 to reset, the central shaft 166 moves upward, causing the second spur gear 165 to disengage and the third spur gear 214 to mesh with the first spur gear 164, the rotation speed of the central shaft 166 decreases, and the vibrating hammer 15 switches to low-frequency striking. S5. During the lifting and lowering of the top plate 213, the pull rope 318 is pulled synchronously. The pull rope 318 drives the first panel 313 to slide along the outer ring 312, thereby compressing or releasing the compression spring 314. In the wet material scenario, the pull rope 318 is less tightened, the compression spring 314 has a large tension, and the rapping hammer 15 has a stronger striking force. In the dry material scenario, the pull rope 318 is more tightened, the compression spring 314 has a moderate tension, and the rapping hammer 15 has a weaker striking force to avoid material splashing. S6. After the material is completely unloaded, turn off the motor 162, reset the discharge plate 13 to close the discharge port, and push the elastic telescopic rod 215 to push the hopper 12 and other components back to their initial state.
