Description

Technical Field

[0001] This invention relates to the field of microbial agent preparation technology, specifically to a microbial agent preparation device for targeted regulation of soil health and its usage method. Background Technology

[0002] Microbial inoculants are live bacterial preparations made by industrially producing and propagating target microorganisms (effective bacteria), and then using porous materials as adsorbents (such as peat moss and vermiculite) to adsorb the fermentation broth of the bacteria. These inoculants are used for seed dressing or root dipping, and have direct or indirect effects such as improving soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of the rhizosphere microbial community, and degrading toxic substances.

[0003] Currently, a Chinese patent application with application number CN202220690643.3 discloses a device for preparing microbial agents, including a preparation device, a support, a motor, and a stirring rod. The support is installed at the top of the preparation device. The device for preparing microbial agents also includes: an additive component installed on the right side of the outer wall of the preparation device; a storage component installed on the left side of the outer wall of the preparation device; and a filter component installed inside the storage component.

[0004] The storage component includes: a support plate, fixed to the top left side of the outer wall of the vessel; an outer shell, threaded to the bottom end of the support plate; a water inlet pipe, inserted into the top left side of the outer shell; and a water filling pipe, inserted into the bottom right side of the outer shell; wherein, the other end of the water filling pipe is inserted into the vessel, and the outer shell is used to store the water used in the preparation of the microbial agent.

[0005] The filter component includes: a mesh cylinder inserted into the interior of the outer shell; a cover fixed to the bottom end of the mesh cylinder; a vertical rod threaded to the center of the top end of the cover; a box body equidistantly fitted onto the outer wall of the vertical rod; insert blocks fixed to both sides of the outer wall of the box body; a fixing block fixed to the left side of the cover; an insert rod fixed to the top end of the fixing block; and a sleeve fitted onto the outer wall of the insert rod. The outer wall of the sleeve is machined with bolts for fixing the insert rod inside the sleeve, and the right side of the sleeve is fixedly connected to the outer wall of the outer shell.

[0006] In the aforementioned prior art, water enters the outer shell through the inlet pipe, and then is filtered through the mesh cylinder. The water then enters the inner shell through the through holes on the shell and is purified by quartz sand and activated carbon. The filtered water is then added to the interior of the vessel through the water inlet pipe. However, during the process of adding water to the vessel, as the mesh cylinder filters the water, the filtered impurities clog the mesh cylinder, reducing the filtration efficiency of the mesh cylinder and thus reducing the flow rate of water entering the vessel. Cleaning the mesh cylinder requires stopping the water inlet pipe, which also reduces the flow rate of water entering the vessel, making it inconvenient to use. Therefore, the applicant has developed a new technical solution in actual production to solve the above-mentioned technical problems. Summary of the Invention

[0007] To address the aforementioned technical shortcomings, the present invention aims to provide a microbial agent preparation device and its usage method for targeted regulation of soil health. This device has the advantage of allowing the screen cylinder (filter plate) to be cleaned or replaced without stopping the water intake, thereby reducing the impact on the water flow rate entering the reactor when cleaning or replacing the filter plate.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This invention provides a microbial agent preparation device for targeted regulation of soil health, comprising a vessel body, two filter plates, and a mounting plate mounted on one side above the vessel body. The mounting plate has two opposing mounting shafts on its side away from the vessel body. The ends of the two mounting shafts away from the mounting plate are connected by a disc. A circular groove is coaxially formed inside the disc. Both filter plates are positioned within the circular groove via a switching element. A water inlet pipe communicating with the circular groove is located at the bottom of the disc. A water outlet pipe communicating with the circular groove is located below one side of the disc on the circular groove. The end of the water outlet pipe away from the disc passes through the mounting plate and communicates with the vessel body. The end of the water outlet pipe communicating with the circular groove is located on one side of the two filter plates. The water inlet pipe corresponds to one of the filter plates. The switching element is used to move the two filter plates within the circular groove. The disc is provided with a pick-and-place element corresponding to one of the filter plates on the switching element.

[0010] By adopting the above technical solution, the inlet and outlet water pipes have the same flow rate. The inlet water pipe's flow rate is D, and the filter plate's flow rate is F, where F is greater than D. In use, the external water source is connected to the inlet water pipe, and the water enters the circular groove through the inlet water pipe. Then, the water is filtered through the filter plate corresponding to the inlet water pipe. The filtered water is discharged into the vessel body through the outlet water pipe. During the process of filling the vessel body with water, when the filter plate corresponding to the inlet water pipe becomes clogged until F is less than D, and the filter plate needs to be replaced or cleaned, the two filter plates are simply moved in the circular groove by the switching component. At this time, the other filter plate will correspond to the inlet water pipe. After the switching, the other filter plate corresponding to the inlet water pipe can continue to filter the water without affecting the flow rate of water entering the vessel body. After the switching, the filter plate that needs to be cleaned or replaced can be removed from the switching component by the pick-and-place component for cleaning or replacement. This achieves the goal of cleaning or replacing the filter plate without stopping the water supply, thereby reducing the impact on the flow rate of water entering the vessel body when cleaning or replacing the filter plate.

[0011] Preferably, the switching component includes a rotating ring coaxially and rotatably sealed in a circular groove. The disc is provided with a rotating component for driving the rotating ring to rotate in the circular groove. The inner wall of the rotating ring is provided with two vertically opposite connecting grooves. The two filter plates are respectively installed in the two connecting grooves by mounting components. The water inlet pipe is connected to the connecting groove located below. The end of the water outlet pipe connected to the circular groove is located on the lower inner side of the rotating ring.

[0012] Preferably, the pick-and-place component includes a sleeve disposed at the top of the disc, and a collar is threadedly connected to the outer wall of the sleeve, the top of the collar being provided with an end cap for sealing the opening of the sleeve.

[0013] Preferably, the rotating component includes a connecting shaft and a rotating groove coaxially formed on the side of the disc opposite to the mounting plate, and a rotating shaft is rotatably connected in the rotating groove. The connecting shaft is horizontally located inside the rotating ring and fixedly connected to the inner wall of the rotating ring. One end of the rotating shaft extends into the circular groove and is fixedly connected to the center of one side of the connecting shaft. The disc is provided with a rotating motor for driving the rotating shaft to rotate.

[0014] Preferably, the mounting component includes a mounting cylinder disposed on the inner wall of the rotating ring near one end of the connecting groove. The connecting groove is circular and communicates with the mounting cylinder. The inner diameter of the mounting cylinder is the same as the diameter of the connecting groove. A threaded cylinder is threadedly connected to the inner wall of the mounting cylinder, and a mounting ring is coaxially fixedly connected to the inner wall of the threaded cylinder. The filter plate is detachably connected to the side of the mounting ring away from the axis of the rotating ring. The inner diameter of the sleeve is larger than the diameter of the connecting groove.

[0015] Preferably, the threaded cylinder has two inverted U-shaped rings at one end near the outer side of the rotating ring, and both rings are located in the connecting groove and on both sides of the cylinder opening.

[0016] Preferably, the outer wall of the rotating ring is provided with an annular groove coaxially, and the two connecting grooves are connected to the annular groove. The disc is provided with an observation window vertically above the middle of the side away from the mounting plate, and the observation window corresponds to the inner side of the rotating ring.

[0017] Preferably, a first scraper and a second scraper are provided between opposite sides of the annular groove, and the first scraper and the second scraper are opposite each other. The side of the first scraper away from the bottom of the annular groove contacts the groove wall of the circular groove, and the upper surface of the first scraper is inclined. The side of the second scraper away from the bottom of the annular groove contacts the groove wall of the circular groove, and the lower surface of the second scraper is inclined. A slot is provided at the end of the first scraper and the second scraper near the bottom of the annular groove. A collection element for collecting impurities on the first scraper is provided at the end of the disc near the first scraper.

[0018] Preferably, the collecting component includes a rectangular groove formed on the side of the disc near the first scraper. A collecting box is detachably connected to one end of the outer wall of the disc near the rectangular groove, and the collecting box closes the opening of the rectangular groove. The end of the collecting box away from the disc is inclined downward, and the upper surface of the first scraper is flush with the bottom wall of the rectangular groove.

[0019] Another objective of this invention is to provide a method for using a microbial agent preparation device for targeted regulation of soil health, including the same flow rate of the inlet pipe (7) and the outlet pipe (8), the flow rate of the inlet pipe (7) being D, the flow rate of the filtered water by the filter plate (2) being F, where F is greater than D. In use, an external water source is connected to the inlet pipe (7), and the water enters the circular trough (6) through the inlet pipe (7), and then the water is filtered through the filter plate (2) corresponding to the inlet pipe (7). The filtered water is discharged into the vessel body (1) from the outlet pipe (8).

[0020] During the process of filling the vessel body (1) with water, when the filter plate (2) corresponding to the water inlet pipe (7) is blocked until F is less than D, and the filter plate (2) needs to be replaced or cleaned, the two filter plates (2) can be moved in the circular groove (6) by the switching component. At this time, the other filter plate (2) will correspond to the water inlet pipe (7). After the switching, the other filter plate (2) corresponding to the water inlet pipe (7) can continue to filter the water.

[0021] After the change, the filter plate (2) that needs to be cleaned or replaced on the change part can be removed by taking and putting the part, and then cleaned or replaced.

[0022] The beneficial effects of this invention are as follows: the inlet and outlet pipes have the same flow rate, with the inlet pipe's flow rate being D and the filter plate's flow rate being F, where F is greater than D. In use, an external water source is connected to the inlet pipe, and water enters the circular groove through the inlet pipe. The water is then filtered by the filter plate corresponding to the inlet pipe. The filtered water is discharged into the vessel body through the outlet pipe. During the process of filling the vessel body with water, if the filter plate corresponding to the inlet pipe becomes clogged until F is less than D, requiring replacement or cleaning of the filter plate, simply use a switching component to move the two filter plates within the circular groove. At this point, the other filter plate will align with the inlet pipe, allowing it to continue filtering water without affecting the flow rate into the vessel body. After the switching, the filter plate requiring cleaning or replacement can be removed from the switching component using a pick-and-place component for cleaning or replacement. This achieves the goal of cleaning or replacing the filter plate without stopping the water supply, thereby reducing the impact on the flow rate of water entering the vessel body during filter plate cleaning or replacement.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: A device for preparing microbial agents that target and regulate soil health, such as... Figure 1 and Figure 2 and Figure 3 The apparatus includes a vessel body 1, two filter plates 2, and a mounting plate 3 mounted on one side above the vessel body 1. The mounting plate 3 has two vertically opposite mounting shafts 4 on its side away from the vessel body 1. The ends of the two mounting shafts 4 away from the mounting plate 3 are connected by a disc 5. A circular groove 6 is coaxially arranged inside the disc 5. Both filter plates 2 are positioned within the circular groove 6 via a switching element. A water inlet pipe 7 communicating with the circular groove 6 is located at the bottom of the disc 5. A water outlet pipe 8 communicating with the circular groove 6 is located below one side of the disc 5. The end of the water outlet pipe 8 away from the disc 5 passes through the mounting plate 3 and communicates with the vessel body 1. The end of the water outlet pipe 8 communicating with the circular groove 6 is located on one side of the two filter plates 2. The water inlet pipe 7 corresponds to one of the filter plates 2. The switching element is used to move the two filter plates 2 within the circular groove 6. The disc 5 has a pick-and-place element corresponding to one of the filter plates 2 on the switching element.

[0035] like Figure 1 and Figure 2 and Figure 3The inlet pipe 7 and outlet pipe 8 have the same flow rate, D. The flow rate of water filtered by filter plate 2 is F, where F is greater than D. In use, an external water source is connected to inlet pipe 7, and water enters the circular trough 6 through inlet pipe 7. The water is then filtered by filter plate 2 corresponding to inlet pipe 7. The filtered water is discharged into vessel 1 through outlet pipe 8. During the process of filling vessel 1 with water, if filter plate 2 corresponding to inlet pipe 7 becomes clogged until F is less than D, and filter plate 2 needs to be replaced or cleaned, simply use the switching element to move the two filters... Plate 2 is repositioned within the circular groove 6. At this time, another filter plate 2 will correspond to the water inlet pipe 7. After the repositioning, the other filter plate 2 corresponding to the water inlet pipe 7 can continue to filter water without affecting the flow rate of water entering the vessel body 1. After the repositioning, the filter plate 2 that needs to be cleaned or replaced can be removed from the repositioning part by the pick-and-place device for cleaning or replacement. This allows the filter plate 2 to be cleaned or replaced without stopping the water inlet, thereby reducing the impact on the flow rate of water entering the vessel body 1 when cleaning or replacing the filter plate 2.

[0036] like Figure 3 and Figure 4 and Figure 5 The switching component includes a rotating ring 9 that is coaxially rotated and sealed in a circular groove 6. A rotating component is provided on the disc 5 to drive the rotating ring 9 to rotate in the circular groove 6. Two vertically opposite connecting grooves 10 are provided on the inner wall of the rotating ring 9. The two filter plates 2 are respectively installed in the two connecting grooves 10 through mounting components. The water inlet pipe 7 is connected to the lower connecting groove 10. The end of the water outlet pipe 8 that is connected to the circular groove 6 is located on the lower inner side of the rotating ring 9. The picking and placing component includes a sleeve 12 set at the top of the disc 5, and a collar 13 is threaded on the outer wall of the sleeve. The top of the collar 13 is provided with an end cap 14 for sealing the opening of the sleeve 12.

[0037] like Figure 3 and Figure 4 and Figure 5Water enters the circular groove 6 through the inlet pipe 7, and then enters the rotating ring 9 through the lower connecting groove 10. The filter plate 2 in the lower connecting groove 10 filters the water passing through it. The filtered water then enters the rotating ring 9 and is discharged into the vessel body 1 through the outlet pipe 8. When it is necessary to rotate the two filter plates 2, simply rotate the rotating ring 9 180 degrees using a rotating component. This will cause the upper and lower connecting grooves 10 to be switched. The filtered water then passes through the filter plate 2 in the switched connecting groove 10... The water can continue to be filtered without affecting the flow rate of water entering the vessel 1. After the change, the collar 13 is unscrewed from the sleeve 12, at which point the end cover 14 can be released from the sleeve 12. Then, the filter plate 2 located in the upper connecting groove 10 can be removed through the mounting parts, and the filter plate 2 can be taken out from the sleeve 12 for cleaning or replacement. This achieves the purpose of cleaning or replacing the filter plate 2 without stopping the water intake, thereby reducing the impact on the flow rate of water entering the vessel 1 when cleaning or replacing the filter plate 2.

[0038] like Figure 3 and Figure 4 The rotating component includes a connecting shaft 15 and a rotating groove 16 coaxially formed on the side of the disc 5 away from the mounting plate 3. A rotating shaft 17 is rotatably connected in the rotating groove 16. The connecting shaft 15 is horizontally located inside the rotating ring 9 and is fixedly connected to the inner wall of the rotating ring 9. One end of the rotating shaft 17 extends into the circular groove 6 and is fixedly connected to the center of one side of the connecting shaft 15. The disc 5 is provided with a rotating motor 18 for driving the rotating shaft 17 to rotate. The purpose of this arrangement is that when it is necessary to drive the rotating ring 9, it is only necessary to turn on the rotating motor 18. At this time, the rotating shaft of the rotating motor 18 will drive the connecting shaft 15 to rotate through the rotating shaft 17. At this time, the connecting shaft 15 will drive the rotating ring 9 to rotate in the circular groove 6 along the rotation axis of the connecting shaft 15. It is simple and convenient to use.

[0039] like Figure 3 The mounting components include a mounting cylinder 19 located on the inner wall of the rotating ring 9 near one end of the connecting groove 10. The connecting groove 10 is circular and communicates with the mounting cylinder 19. The inner diameter of the mounting cylinder 19 is the same as the diameter of the connecting groove 10. A threaded cylinder 20 is threadedly connected to the inner wall of the mounting cylinder 19, and a mounting ring 21 is coaxially fixedly connected to the inner wall of the threaded cylinder 20. The filter plate 2 is detachably connected to the side of the mounting ring 21 opposite to the axis of the rotating ring 9. The inner diameter of the sleeve 12 is larger than the diameter of the connecting groove 10. The purpose of this arrangement is that when it is necessary to remove the filter plate 2 in the upper connecting groove 10, simply unscrew the threaded cylinder 20 from the mounting cylinder 19, then remove the threaded cylinder 20 from the sleeve 12, and then remove the filter plate 2 from the mounting ring 21 inside the threaded cylinder 20. This allows for cleaning or replacement of the filter plate 2. The disassembly and assembly are simple, and the disassembly and assembly of the filter plate 2 located in the upper connecting groove 10 will not affect the operation of the filter plate 2 located in the lower connecting groove 10. It is simple and convenient to use.

[0040] like Figure 3 A housing 22 is detachably connected to the side of the mounting ring 21 near the axis of the rotating ring 9. The housing 22 closes the opening of the mounting ring 21. Several circular holes 23 are formed at the top of the housing 22, corresponding vertically to the filter plate 2. The housing 22 contains a quartz sand layer and an activated carbon layer. This arrangement ensures that after water is filtered by the filter plate 2, it enters the housing 22 through the circular holes 23, is purified by the quartz sand and activated carbon layers, and then exits through the circular holes 23 on the side of the housing 22 away from the mounting ring 21. The water is located inside the rotating ring 9 and then injected into the vessel body 1 through the water outlet pipe 8. When the threaded cylinder 20 is unscrewed from the mounting cylinder 19 and then removed from the sleeve 12, the filter plate 2 and the box body 22 located at the upper connecting groove 10 can be removed from the disc 5. Then the filter plate 2 can be removed from the mounting ring 21 inside the threaded cylinder 20 for cleaning or replacement, and the box body 22 can be removed from the mounting ring 21 for replacement. The filtration flow rate of the quartz sand layer and activated carbon layer in the box body 22 is the same as the filtration flow rate of the filter plate 2, making it simple and convenient to use.

[0041] like Figure 3 and Figure 4 The threaded cylinder 20 has two inverted U-shaped rings 26 at one end near the outer side of the rotating ring 9. Both rings 26 are located in the connecting groove 10 and on both sides of the opening of the threaded cylinder 20. The purpose of this arrangement is to make it easy to rotate the threaded cylinder 20 through the rings 26 on the threaded cylinder 20, which is simple and convenient to use.

[0042] like Figure 3 and Figure 4 and Figure 5 The outer wall of the rotating ring 9 is coaxially provided with an annular groove 27, and the two connecting grooves 10 are connected to the annular groove 27. The disc 5 is vertically provided with an observation window 28 on the upper middle side of the side away from the mounting plate 3, and the observation window 28 corresponds to the inner side of the rotating ring 9.

[0043] like Figure 3 and Figure 4 and Figure 5 Water enters the annular groove 27 on the rotating ring 9 from the inlet pipe 7, and then passes through the filter plate 2 in the connecting groove 10 located below before entering the rotating ring 9. At this time, the water level in the annular groove 27 is located in the lower middle part of the annular groove 27 (e.g., Figure 6 As the filter plate 2 in the lower connecting channel 10 gradually becomes clogged with the filtration of water, until the flow rate F of the filtered water is less than the flow rate D of the inlet pipe 7, the water level in the annular channel 27 will gradually rise. When the water level rises to the opening of the upper connecting channel 10, such as... Figure 7Water will flow into the upper connecting channel 10, and then flow into the rotating ring 9 after being filtered by the filter plate 2 in the upper connecting channel 10. At this time, when the filter plate 2 in the lower connecting channel 10 is blocked, the water can be automatically filtered by the filter plate 2 in the upper connecting channel 10, which reduces the occurrence of reduced water flow into the vessel 1 due to the blockage of the filter plate 2 in the lower connecting channel 10.

[0044] The water can be easily observed through the observation window 28 to see if it flows into the rotating ring 9 after being filtered by the filter plate 2 in the upper connecting groove 10. When it is observed that the water flows into the rotating ring 9 after being filtered by the filter plate 2 in the upper connecting groove 10, it means that the filter plate 2 in the lower connecting groove 10 needs to be replaced. Then, the rotating ring 9 is rotated 180 degrees to swap the positions of the upper and lower connecting grooves 10. After the two connecting grooves 10 are swapped, the water level in the annular groove 27 will drop until the water level drops below the opening of the upper connecting groove. Then, the clogged filter plate 2 can be removed from the connecting groove 10 through the mounting parts for replacement or cleaning. It is simple and convenient to use.

[0045] like Figure 4 A first scraper 29 and a second scraper 30 are provided between opposite sides of the annular groove 27, and the first scraper 29 and the second scraper 30 are opposite each other. The side of the first scraper 29 away from the bottom of the annular groove 27 is in contact with the wall of the circular groove 6, and the upper surface of the first scraper 29 is inclined. The side of the second scraper 30 away from the bottom of the annular groove 27 is in contact with the wall of the circular groove 6, and the lower surface of the second scraper 30 is inclined. A slot is provided at the end of the first scraper 29 and the second scraper 30 near the bottom of the annular groove 27. A collection element for collecting impurities on the first scraper 29 is provided at the end of the disc 5 near the first scraper 29.

[0046] like Figure 4 When the rotating ring 9 rotates 180 degrees, the impurities on the bottom wall of the circular groove 6 can be scraped off by the second scraper 30. After the rotating ring 9 rotates 180 degrees, the second scraper 30 and the first scraper 29 are swapped. After the swap, the inclined surface of the second scraper 30 faces upward and the inclined surface of the first scraper 29 faces downward. At this time, the second scraper 30 will correspond to the collecting component. The impurities can then slide to the collecting component through the inclined surface of the second scraper 30. The collecting component can then collect the impurities. Similarly, when the rotating ring 9 rotates 180 degrees in the same direction again, the impurities on the bottom wall of the circular groove 6 can be scraped off by the first scraper 29. The rotation direction of the rotating ring 9 is always counterclockwise. Since both the first scraper 29 and the second scraper 30 have slots, the first scraper 29 and the second scraper 30 will not affect the rise of the water level in the annular groove 27. It is simple and convenient to use.

[0047] like Figure 4The collecting component includes a rectangular groove 31 formed on the side of the disc 5 near the first scraper 29. A collecting box 32 is detachably connected to one end of the outer wall of the disc 5 near the rectangular groove 31, and the collecting box 32 closes the opening of the rectangular groove 31. The end of the collecting box 32 away from the disc 5 is inclined downwards, and the upper surface of the first scraper 29 is flush with the bottom wall of the rectangular groove 31. The purpose of this arrangement is that, through the cooperation of the collecting box 32 with the inclined first scraper 29 and the second scraper 30, the impurities filtered out on the bottom wall of the circular groove 6 can be collected, which is simple and convenient to use.

[0048] Example 2: A method of using a microbial agent preparation device for targeted regulation of soil health, including the same flow rate of inlet pipe 7 and outlet pipe 8, the flow rate of inlet pipe 7 being D, the flow rate of water filtered by filter plate 2 being F, where F is greater than D. In use, an external water source is connected to inlet pipe 7, water enters circular trough 6 through inlet pipe 7, and then the water is filtered by filter plate 2 corresponding to inlet pipe 7. The filtered water is discharged into vessel 1 from outlet pipe 8.

[0049] During the process of filling the vessel 1 with water, when the filter plate 2 corresponding to the water inlet pipe 7 becomes clogged until F is less than D, and the filter plate 2 needs to be replaced or cleaned, the two filter plates 2 can be moved in the circular groove 6 by the switching component. At this time, the other filter plate 2 will correspond to the water inlet pipe 7. After the switching, the other filter plate 2 corresponding to the water inlet pipe 7 can continue to filter the water.

[0050] After the shift, remove the filter plate 2 that needs to be cleaned or replaced from the shifting part using the pick-and-place tool, and then clean or replace it.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
