Description

Technical Field

[0001] The invention relates to the technical field of fertilizer manufacturing, in particular to bacteria seed adding equipment for producing biological organic fertilizer. Background Art

[0002] During the production of bio-organic fertilizer, a variety of functional bacterial strains need to be added to the base material, and a stirring process is used to ensure that the bacterial strains are evenly distributed in the base material to improve fermentation efficiency.

[0003] The traditional method of adding bacterial strains mainly uses an atomizing nozzle to spray the bacterial strain concentrate. The atomizing nozzle can expand the spraying area of ​​the bacterial strain concentrate, so that the bacterial strain can be distributed on the plane of the upper cross-section of the base material; combined with the base material stirring process, the vertical material displacement is used to avoid the bacterial strain concentrate from adhering to a certain height layer, thereby achieving initial mixing uniformity of the base material and the bacterial strain.

[0004] The production of bio-organic fertilizers often requires the addition of multiple functional bacterial strains. The preset spraying volumes of different bacterial stock solutions vary, resulting in different target spraying times for each bacterial strain. The spraying time has a two-way impact on bacterial strain addition:

[0005] The stirring time is too short: the original liquid of the bacterial strain remains concentrated on the upper layer of the base material, and the stirring time needs to be extended to promote the mixing of the upper and lower layers, resulting in reduced production efficiency;

[0006] Too long: The base material at a certain height reaches the upper end again due to the stirring cycle and may be sprayed a second time, which not only destroys the uniformity of the bacterial distribution, but also increases the unnecessary spraying time;

[0007] refer to Figure 11 Because the spraying channel of traditional atomizing nozzles is fixed, the spraying speed is positively correlated with the spraying pressure, which makes the spraying speed positively correlated with the spraying area. If the spraying speed is adjusted to control the spraying time of a fixed volume of solution, it will directly lead to a change in the atomization coverage area, and ultimately cause a decrease in the mixing uniformity of the base material and the bacterial stock solution.

DETAILED DESCRIPTION

[0040] See also Figures 1-10The present invention provides a technical solution: a bacterial strain adding device for producing biological organic fertilizer, comprising a fermentation tank 1; and further comprising a plurality of injection pipes 2, wherein the plurality of injection pipes 2 are embedded in the upper end of the fermentation tank 1 and the lower end of the injection pipe 2 is inserted into the fermentation tank 1;

[0041] A piston 3 is vertically slidably connected in the liquid injection tube 2, and the piston 3 is provided with an exhaust mechanism for exhausting gas and a driving mechanism for driving the piston 3;

[0042] The lower end of the inner wall of the injection tube 2 is vertically elastically slidably connected to a piston 2 4, and the lower end of the piston 2 4 is vertically fixedly connected to a slide rod 5, which passes through the lower end of the injection tube 2. Telescopic rods 6 are hinged on both sides of the lower end of the slide rod 5. A bracket 7 for supporting the rotation of the telescopic rod 6 is provided at the lower end of the injection tube 2, and the bracket 7 is supported at the middle position of the telescopic rod 6. The ends of the two telescopic rods 6 away from the slide rod 5 are hinged together with a ring 1 8, and a ring 2 9 is provided below the ring 1 8;

[0043] The ring 1 8 is provided with a locking mechanism, which is in transmission connection with the ring 2 9 and can make the upper end of the ring 2 9 close to the lower end of the ring 1 8 and lock it;

[0044] The lower end of the injection tube 2 is elastically rotatable in a circular array and is provided with a plurality of adapter components, the end of the adapter component close to the axis of the injection tube 2 is provided with a transmission component, and the transmission components are fixedly connected to the lower end of the ring 2 9; the end of the adapter component away from the axis of the injection tube 2 is provided with a nozzle 10, the nozzle 10 is connected to the injection tube 2 through the adapter component, and the adapter component is externally connected to a pipe connected to the injection tube 2.

[0045] Various strains are added to the respective injection tubes 2. When a specific strain needs to be added to the fermentation tank 1, the injection tube 2 with the strain added sprays the strain stock solution into the fermentation tank 1 through the nozzle 10.

[0046] During this process, the driving mechanism first drives the piston 13 to move downward at a uniform speed. The bacterial stock solution in the injection tube 2 is squeezed by the piston 13, and the pressure increases, so that the piston 24 overcomes the elastic force and moves downward (moving distance L). Then the piston 24 drives the slide bar 5 downward, so that the end of the telescopic rod 6 hinged to the slide bar 5 moves downward. Further, the telescopic rod 6 rotates around the bracket 7 and drives the ring 18 to move vertically upward. At the same time, the locking mechanism controls the upper end of the ring 29 to be close to the lower end of the ring 18 and locks it, so that the ring 29 moves upward with the ring 18. The ring 29 drives the adapter through the transmission assembly. The end of the assembly near the axis of the injection pipe 2 moves upward, causing the transmission assembly to rotate, and at the same time, the end of the transmission assembly connected to the nozzle 10 rotates downward. Furthermore, during this process, as the hydraulic pressure in the injection pipe 2 increases, the bacterial stock solution is sprayed out from the nozzle 10. In this process, since the number of nozzles 10 is fixed, the faster the piston 13 moves downward (the corresponding spraying amount of the nozzle 10 is greater), the greater the hydraulic pressure in the injection pipe 2, which makes the piston 2 4 move downward more. Furthermore, from the above, it can be seen that the transmission assembly drives the nozzle 10 to rotate downward with a greater amplitude.

[0047] When the bacterial stock solution is sprayed, the piston 1 stops moving downward. Correspondingly, the stock solution in the injection tube 2 is squeezed by the piston 2 4 under the elastic force. The piston 2 4 gradually moves upward under the elastic force, so that the stock solution is sprayed from the nozzle 10 to the outside of the injection tube 2. At the same time, the hydraulic pressure in the injection tube 2 gradually decreases, causing the nozzle 10 to rotate upward and reset until the hydraulic pressure in the injection tube 2 decreases to a level that prevents the nozzle 10 from spraying. At this time, the locking mechanism cancels the restriction on the ring 2 9, allowing the ring 2 9 to reset under the elasticity of the adapter assembly, and the adapter assembly resets under its own elastic force.

[0048] In the above work process, if Figure 11 During the process of spraying the original liquid by the nozzle 10, the initial angle of the original liquid leaving the nozzle 10 is fixed, and its spraying range increases with the increase of the hydraulic pressure in the injection pipe 2 (the hydraulic pressure increases, the spraying speed of the nozzle 10 increases, Figure 11 In the spraying process, the spraying speed v3>v2>v1), which causes the sprayed liquid to fall on a fixed plane. Figure 11 If the initial velocity of the liquid leaving the nozzle 10 is too slow, the spraying range is small, resulting in incomplete spraying on the fixed plane; if the initial velocity of the liquid leaving the nozzle 10 is too fast, the spraying range is large, resulting in a large amount of liquid being sprayed onto the side wall of the fermentation tank 1, increasing the difficulty of mixing;

[0049] like Figure 12 When the hydraulic pressure in the injection pipe 2 gradually increases (the corresponding nozzle 10 sprays the original liquid at a faster initial speed), the present invention increases the downward rotation amplitude of each nozzle 10 corresponding to the injection pipe 2, so that the spray coverage surface of each nozzle 10 approaches the center of the fermentation tank 1 (the smaller the downward rotation amplitude of the nozzle 10, the smaller the angle between the nozzle 10 and the vertical line, Figure 12In the embodiment, the angle between the nozzle 10 and the vertical line is θ3>θ2>θ1), thereby preventing the raw liquid from being sprayed onto the side wall of the fermentation tank 1 in large quantities; correspondingly, when the hydraulic pressure in the injection pipe 2 decreases and the spraying range of a single nozzle 10 decreases, each nozzle 10 reduces its downward rotation amplitude so that the spraying coverage surface of each nozzle 10 approaches the side wall of the fermentation tank 1, so that the raw liquid can be sprayed on the fixed surface;

[0050] The mixture between the original liquid and the base material is not completely uniform, but the base material is covered with bacteria, while preventing excessive enrichment of bacteria in local areas; so that during the fermentation process, all base materials can be fermented, reducing the time for bacteria to multiply and spread to base materials without bacteria, thereby increasing the fermentation speed.

[0051] Compared with the traditional atomizing nozzle with a fixed injection channel, the present invention uses multiple rotatable nozzles 10, and the rotation amplitude increases with the increase of the hydraulic pressure in the injection pipe 2; so that the overall spray coverage of each nozzle 10 can be changed, and in this way, the change in the spray range of the nozzle 10 caused by the hydraulic pressure change in the injection pipe 2 is compensated, ensuring as much as possible that the upper cross-section of the base material can be sprayed by the nozzle 10; in this way, the base material in the fermentation tank 1 is mixed with the bacterial stock solution as much as possible.

[0052] Furthermore, the locking mechanism includes a cylinder 11 fixedly connected to the upper end of ring 1 8 , and the output shaft of the cylinder 11 passes through ring 1 8 and is fixedly connected to the end of ring 2 9 .

[0053] When the hydraulic pressure in the injection pipe 2 rises to the point where the original liquid can be sprayed out from the nozzle 10, the cylinder 11 starts, so that the output shaft of the cylinder 11 drives the ring 2 9 to move toward the ring 1 8, so that the upper end of the ring 2 9 is close to the lower end of the ring 1 8 and remains there; when the hydraulic pressure in the injection pipe 2 drops to the point where the original liquid can no longer be sprayed out from the nozzle 10, the cylinder 11 stops running, so that the output shaft can freely move vertically, and thus the ring 2 9 can freely move vertically.

[0054] Furthermore, the piston 2 4 is externally connected to a displacement sensor, which is used to control the start or stop of the cylinder 11.

[0055] When the hydraulic pressure in the injection pipe 2 rises to the point where the original liquid can be sprayed out from the nozzle 10, the piston 2 4 moves vertically downward to below a fixed height. Similarly, when the hydraulic pressure in the injection pipe 2 drops to the point where the original liquid cannot be sprayed out from the nozzle 10, the piston 2 4 moves vertically downward to above the fixed height. Therefore, a displacement sensor is provided. By monitoring the vertical height of the piston 2 4 through the displacement sensor, the hydraulic state in the injection pipe 2 can be determined.

[0056] Furthermore, the lower end of the injection tube 2 is fixedly connected to a sealing shell 12, and the adapter assembly is rotatably connected to the side wall of the sealing shell 12 and sealed with the side wall of the sealing shell 12; one end of the adapter assembly with the nozzle 10 is located outside the sealing shell 12, and the other end is located inside the sealing shell 12; the ring 1 8, ring 2 9 and the lower end of the injection tube 2 are all located inside the sealing shell 12.

[0057] By providing a sealing shell 12, the ring 1 8, the ring 2 9 and the upper components as well as the related components provided at the lower end of the injection tube 2 are placed in the sealing shell 12 for protection to avoid being affected by the humid environment.

[0058] Furthermore, the adapter assembly includes a shell 13, which radially penetrates the side wall of the sealing shell 12 and is rotatably connected to the side wall of the sealing shell 12. The upper and lower side walls of the shell 13 are fixedly connected with fan blocks 14, and the fan blocks 14 are used to block the connection gap between the shell 13 and the side wall of the sealing shell 12; a connecting pipe 15 is fixedly connected inside the shell 13; one end of the connecting pipe 15 is fixedly connected to the nozzle 10, and the other end is fixedly connected to the pipeline, and the nozzle 10 is embedded in one end of the shell 13 outside the sealing shell 12.

[0059] Furthermore, the end of the connecting pipe 15 is fixedly connected to a joint 16, the inner hole of the joint 16 is composed of channel 17, channel 2 18 and a transition section 19 located between channel 17 and channel 2 18, and the inner diameter of channel 2 18 is larger than that of channel 17; a sealing ball 20 is elastically provided in the channel 2 18, the diameter of the sealing ball 20 is smaller than the inner diameter of channel 2 18, and the sealing ball 20 can block the transition section 19 under the action of elastic force; the joint 16 is located at one end of channel 2 18 and is fixedly connected to the nozzle 10.

[0060] When the pressure in the injection pipe 2 increases, the raw liquid in the injection pipe 2 tends to push the sealing ball 20 from the transition section 19 into the second channel 18 under the action of the pressure. When the pressure in the injection pipe 2 increases to a certain level, the sealing ball 20 overcomes the elastic force and enters the second channel 18, so that the transition section 19 is no longer blocked by the sealing ball 20. Further, the raw liquid in the injection pipe 2 is sprayed out of the nozzle 10 through the joint 16.

[0061] The present invention provides a joint 16 with a sealing ball 20, so that the nozzle 10 will spray the original liquid only after the hydraulic pressure in the injection pipe reaches a threshold value. Furthermore, the nozzle 10 will spray the original liquid only after it is rotated downward by a certain angle; in this way, the nozzle 10 is prevented from leaking the original liquid when the nozzle 10 starts working or ends working.

[0062] Furthermore, a protection block 21 is fixedly connected to the lower end of the liquid injection tube 2 corresponding to the position of the shell 13. The protection block 21 can be engaged with the end of the shell 13 to seal and protect the nozzle 10 at the end of the shell 13.

[0063] In the initial state, the shell 13 presses against the protective block 21 under the action of elastic force, so that the nozzle 10 at the end of the shell 13 is located in the protective block 21, and the protective block 21 seals and protects the nozzle 10; preventing the nozzle 10 from being contaminated by external bacteria during non-working hours, further increasing the purity of the bacterial stock solution when the nozzle 10 sprays the bacterial stock solution, and improving the fermentation quality.

[0064] Furthermore, the transmission assembly includes a guide rail 22 fixedly connected to the lower end of ring 2 9, and the guide rail 22 is elastically slidably connected to a connecting rod 23 along the radial direction of ring 2 9. The end of the connecting rod 23 is rotatably connected to one end of the shell 13 located inside the sealed shell 12.

[0065] During the vertical displacement of the ring 2 9 , the connecting rod 23 thereon is driven to vertically displace, and then the connecting rod 23 drives one end of the housing 13 located in the sealing shell 12 to vertically displace, causing the housing 13 to rotate.

[0066] Furthermore, the driving mechanism includes a screw 24 fixedly connected to the upper end of the piston 3, the upper end of the screw 24 passes through the upper end of the injection tube 2 and is threadedly connected to the injection tube 2, the upper end of the injection tube 2 is provided with a motor 25, the driving shaft of the motor 25 is fixedly connected to the upper end of the screw 24, and an injection hole 26 is vertically penetrated in the screw 24, and the injection hole 26 passes downward through the piston 3, and the side wall of the screw 24 outside the injection tube 2 is provided with an injection device 27, and the injection device 27 is connected to the injection hole 26, and the injection device 27 is used to add bacterial strain concentrate to the injection hole 26, and the exhaust mechanism is provided at the injection hole 26 in the piston 3, and the exhaust mechanism can block the injection hole 26 and discharge the air in the space below the piston 3 in the injection tube 2.

[0067] The bacterial stock solution is added to the injection hole 26 through the injection device 27 , so that the bacterial stock solution enters the injection tube 2 through the injection hole 26 .

[0068] Furthermore, the exhaust mechanism includes a sealing cone 28, the upper half of which is a cylinder and the lower half is a cone; the density of the sealing cone 28 is lower than that of the bacterial stock solution, and a fixed rod 29 coaxial with the screw is vertically fixedly connected in the injection hole 26, and the sealing cone 28 is vertically slidably connected to the fixed rod 29. The lower end of the piston 3 is located at the injection hole 26 and is provided with a chamfer 30, and the conical side wall of the lower half of the sealing cone 28 can be sealed and fitted with the chamfer 30.

[0069] As the amount of bacterial stock solution in the injection tube 2 increases, the liquid surface of the bacterial stock solution moves upward to the injection hole 26 in the screw 24, and the corresponding blocking cone 28 moves up with the liquid surface of the bacterial stock solution under the action of buoyancy until the conical side wall of the lower half of the blocking cone 28 fits with the chamfer 30 in the piston 3, so that there is no air in the lower half of the piston 3 in the injection tube 2; in this way, when the injection tube 2 sprays the bacterial stock solution into the fermentation tank 1, the spraying amount can be controlled to prevent the spraying amount from being reduced due to the presence of air. In the above working process, since the density of the blocking cone 28 is similar to that of the bacterial stock solution, the blocking cone 28 The upper end of the cone 28 is approximately flush with the liquid surface; further, the cone of the lower half of the blocking cone 28 is sunk below the liquid surface, thereby ensuring that when the conical side wall of the lower half of the blocking cone 28 fits with the chamfer 30, the liquid surface of the bacterial seed stock solution is located in the injection hole 26 in the screw 24. At the same time, during the subsequent spraying of the bacterial seed stock solution, when the piston 3 moves downward, the blocking cone 28 at the lower end of the piston 3 and the chamfer 30 of the piston 3 presses the liquid surface downward, thereby subjecting the blocking cone 28 to an upward reaction force, causing the conical side wall of the lower half of the blocking cone 28 and the chamfer 30 to press each other tightly.

[0070] When the bacterial strain liquid in the injection tube 2 is consumed and the bacterial strain liquid needs to be re-injected into the injection tube 2, the piston 3 moves upward. At the same time, the blocking cone 28 moves downward relative to the piston 3 under the action of gravity, so that the conical side wall of the blocking cone 28 is separated from the chamfer 30, and the blocking cone 28 further cancels the sealing effect on the injection hole 26, so that the bacterial strain liquid can be smoothly injected into the injection tube 2 through the injection hole 26.
