Description

Technical Field

[0001] This invention relates to the technical field of microbial agent screening and purification, and particularly to equipment and methods for screening and purifying microbial agents for organic fertilizers. 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 the functions of directly or indirectly improving soil restoration, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora, and degrading toxic substances.

[0003] Current microbial agents are formed by culturing microbial solutions to produce agents with specific active bacteria. These agents contain many macromolecular impurities and need to be screened and purified before they can be prepared into agents. The current purification process usually involves filtering the initial cultured microbial solution through a filter plate to screen for beneficial microbial solutions.

[0004] In the above screening, purification and filtration process, the filter plate is prone to clogging, which affects the filtration efficiency of the microbial agent. Moreover, clogging requires a long downtime, which affects work efficiency. Therefore, we propose a screening and purification equipment and method for microbial agents used in organic fertilizers. Summary of the Invention

[0012] As a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the screening box has movable holes on both the upper and lower walls of its inner cavity, and the inner cavity of the movable holes is movably connected to the adjusting component to facilitate the installation of the adjusting component.

[0013] As a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the adjusting component includes a drive motor, which is fixedly connected to the top of the inverted L-shaped fixed plate, and the output shaft of the drive motor is movably connected to the through hole cavity opened inside the inverted L-shaped fixed plate.

[0014] An active rotating rod is fixedly installed on the output shaft of the drive motor. The outer surfaces of both ends of the active rotating rod are movably connected to the inner cavity of the movable hole. A double-groove active wheel is fixedly sleeved on the outer surface of the active rotating rod. The double-groove active wheel is movably connected to the screening filter element.

[0015] A rotating cylinder is fixedly sleeved on the outer surface of the active rotating rod. The outer surface of the rotating cylinder is movably connected to the outer surface of the partition. An adjusting plate is fixedly installed on the outer surface of the rotating cylinder. The adjusting plate is movably connected to the bottom wall of the inner cavity of the screening box to adjust the direction of the inoculant flow.

[0016] As a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the upper and lower top walls of the inner cavity of the screening box are provided with second fixing holes, and the inner wall of the second fixing hole is fixedly connected to the screening filter element to facilitate the installation of the screening filter element.

[0017] In a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the screening filter element includes a belt, which is movably connected to a double-groove drive wheel. A driven wheel is movably connected to the side of the belt away from the double-groove drive wheel. A driven rotating rod is fixedly installed in the inner cavity of the driven wheel. A second bearing is fixedly sleeved on the outer surface of the driven rotating rod. The outer surface of the second bearing is fixedly connected to the inner wall of the second fixing hole. An installation cylinder is fixedly sleeved on the outer surface of the driven rotating rod. A filter plate is fixedly installed on the outer surface of the installation cylinder. The outer surface of the filter plate is movably connected to a striking element. The filter plate is movably connected to the chamber walls of the first screening chamber and the second screening chamber, so as to facilitate the filtration and purification of the microbial agent.

[0018] As a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the inner cavity top wall of the screening box is provided with a waist-shaped groove, the inner cavity side wall of the waist-shaped groove is provided with a rotating hole, and the inner cavity of the rotating hole is movably connected to the striking element to facilitate the installation of the striking element.

[0019] As a preferred embodiment of the microbial agent screening and purification equipment for organic fertilizer described in this invention, the striking component includes a rotating shaft, which is rotatably connected to the inner cavity of a rotating hole. A third bearing is fixedly sleeved on the outer surface of the rotating shaft, and a connecting rod is fixedly installed on the outer surface of the third bearing. A steel ball is fixedly installed at the end of the connecting rod away from the third bearing, and a striking protrusion is fixedly installed on the outer surface of the steel ball. The striking protrusion is movably connected to the outer surface of the filter plate to facilitate the cleaning of large molecular impurities on the filter plate.

[0020] The purification method of the microbial agent screening and purification equipment for organic fertilizer includes the following steps: S1, the agent is injected into the screening box through the agent feed pipe on the left side, and the tilt position of the adjustment plate is adjusted so that the agent flows to the first screening chamber. At this time, the impact force of the agent drives the paddle to rotate around the first rotating rod as the axis, and the paddle drives the agent into the first screening chamber.

[0021] S2. Based on S1, the bacterial agent flowing into the first screening chamber is screened and filtered by the filter plate. At this time, the bacterial agent passes through the filter plate into the first screening chamber and is discharged through the bacterial agent discharge pipe. However, the large molecular impurities in the bacterial agent adhere to the filter plate. Over time, the filter plate will become clogged, affecting the efficiency of bacterial agent filtration.

[0022] S3. Based on S2, when the filter plate is clogged and affects the filtration efficiency of the microbial agent, the drive motor is started and the injection of microbial agent into the left microbial agent feed pipe is stopped. At this time, the output shaft of the drive motor drives the active rotating rod to rotate, and the active rotating rod drives the rotating cylinder and the adjusting plate to rotate until the adjusting plate is tilted so that the microbial agent flows into the second screening chamber. At the same time, the active rotating rod drives the screening filter element to rotate until the filter plate is perpendicular to the partition. During the rotation of the filter plate, the striking element rotates and strikes the filter plate to generate vibration. The large molecular impurities on the filter plate are dislodged due to the vibration, so as to clean the large molecular impurities on the filter plate. Then, the microbial agent is injected into the right microbial agent feed pipe and flows into the second screening chamber for filtration and purification.

[0023] S4. Based on S3, the bacterial agent flowing into the second screening chamber generates an impact force that drives the paddle to rotate in the opposite direction around the first rotating rod, and the paddle carries the bacterial agent into the second screening chamber.

[0024] S5. Based on S4, repeat the steps in S2 and S3 to filter and purify the bacterial agent. Then, use the first screening chamber and the second screening chamber alternately to filter and purify the bacterial agent in a cyclical manner to avoid long-term downtime and affect work efficiency. At the same time, it can clean the large molecular impurities on the filter plate.

[0025] The beneficial effects of this invention are:

[0026] 1. In this organic fertilizer microbial agent screening and purification equipment, when the filter plate becomes clogged, affecting the filtration efficiency of the agent, the injection of agent into the left-side agent feed pipe is stopped. Then, the rotating double-groove drive wheel drives the belt to rotate, which in turn drives the driven rotating rod to rotate. The driven rotating rod then drives the mounting cylinder to rotate, which in turn drives the filter plate to rotate until the filter plate is perpendicular to the partition again. Simultaneously, agent is injected into the right-side agent feed pipe. At this point, the agent flows into the second screening chamber and is filtered and purified. This cycle is repeated. During this process, the rotating filter plate drives the steel balls to rotate. When the steel ball detaches from the filter plate, it and the striking protrusion rotate under the influence of gravity. The steel ball and striking protrusion rotate around a pivot, striking the filter plate as they fall. The vibrations generated by these impacts clean the large molecular impurities on the filter plate. These impurities, detached from the filter plate, can be further cleaned by an external rinsing device and temporarily discharged through the inner cavity of the bacterial agent discharge pipe. The bacterial agent is then circulated and purified by alternating between the first and second screening chambers. This facilitates the cleaning of large molecular impurities from the filter plate and prevents prolonged downtime from affecting work efficiency.

[0027] 2. This organic fertilizer microbial agent screening and purification equipment injects microbial agents into the screening box through the inner cavity of the agent inlet pipe. At this time, the impact force generated by the microbial agents flowing into the screening box drives the paddle to rotate around the first rotating rod as the axis, and the paddle carries the microbial agents into the screening chamber. During this period, the flow of microbial agents into the first screening chamber or the second screening chamber can be achieved by changing the microbial agent inlet pipe. The rotating paddle also plays a buffering role, which facilitates changing the direction of microbial agent flow and buffering the impact force when the microbial agents flow in.

[0028] 3. In this organic fertilizer microbial agent screening and purification equipment, when the agent flows into the second screening chamber, the drive motor is started. At this time, the output shaft of the drive motor drives the active rotating rod to rotate, which in turn drives the rotating cylinder to rotate. The rotating cylinder is rotatably connected to the outer surface of the partition plate. The rotating cylinder drives the adjusting plate to rotate until the adjusting plate is adjusted so that the agent can flow into the second screening chamber. During this period, the active rotating rod drives the double-groove active wheel to rotate, which in turn drives the screening filter element to rotate, thereby facilitating the adjustment and change of the direction of agent flow, and thus facilitating the filtration and purification of the agent.

[0038] Reference Figure 1-4 The first embodiment of the present invention provides a screening and purification device for microbial agents for organic fertilizer, including a screening box 1. The bottom wall of the inner cavity of the screening box 1 is provided with a partition 2 for separation, forming a first screening chamber 11 and a second screening chamber 12. The inner side wall of the screening box 1 is provided with two microbial agent feeding pipes 3 for feeding. The bottom wall of the inner cavity of the first screening chamber 11 and the second screening chamber 12 is provided with microbial agent discharge pipes 9 for discharging.

[0039] The screening box 1 is equipped with a buffer 4 for buffering the bacterial agent. An inverted L-shaped fixing plate 5 is fixedly installed on the top of the screening box 1. An adjusting component 6 for changing the flow direction of the bacterial agent is provided on the inverted L-shaped fixing plate 5. The adjusting component 6 is movably connected to the interior of the screening box 1.

[0040] The adjusting component 6 is provided with a screening filter 7 for screening and purification. The screening filter 7 is movably connected to the inner cavity of the first screening chamber 11 and the second screening chamber 12. The screening box 1 is provided with a striking component 8 for tapping and vibration. The striking component 8 is movably connected to the screening filter 7.

[0041] The upper and lower walls of the inner cavity of the screening box 1 are provided with first fixing holes 13, and the inner cavity of the first fixing holes 13 is fixedly connected to the buffer 4.

[0042] The buffer component 4 includes a first rotating rod 41. The outer surfaces of the upper and lower ends of the first rotating rod 41 are fixedly sleeved with first bearings 42. The outer surface of the first bearings 42 is fixedly connected to the inner wall of the first fixing hole 13. The outer surface of the first rotating rod 41 is fixedly sleeved with a paddle cylinder 43. The outer surface of the paddle cylinder 43 is fixedly mounted with paddles 44, and the paddles 44 are arranged in a circumferential array on the paddle cylinder 43. The paddles 44 are movably connected to the inner wall of the screening box 1.

[0043] During use, the microbial agent is injected into the screening box 1 through the inner cavity of the microbial agent inlet pipe 3. At this time, the impact force generated by the microbial agent flowing into the screening box 1 drives the paddle 44 to rotate around the first rotating rod 41 as the axis, and the paddle 44 carries the microbial agent into the screening chamber. During this period, the microbial agent can flow into the first screening chamber 11 or the second screening chamber 12 by changing the microbial agent inlet pipe 3. The rotating paddle 44 plays a buffering role, which makes it easy to change the direction of the microbial agent flow and buffer the impact force when the microbial agent flows in. Example 2

[0044] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the upper and lower walls of the inner cavity of the screening box 1 are provided with movable holes 14, and the inner cavity of the movable holes 14 is movably connected to the adjusting member 6.

[0045] The adjusting component 6 includes a drive motor 61, which is fixedly connected to the top of the inverted L-shaped fixed plate 5, and the output shaft of the drive motor 61 is movably connected to the through hole cavity inside the inverted L-shaped fixed plate 5.

[0046] An active rotating rod 62 is fixedly mounted on the output shaft of the drive motor 61. The outer surfaces of both ends of the active rotating rod 62 are movably connected to the inner cavity of the movable hole 14. A double-groove active wheel 63 is fixedly sleeved on the outer surface of the active rotating rod 62. The double-groove active wheel 63 is movably connected to the screening filter element 7.

[0047] A rotating cylinder 64 is fixedly sleeved on the outer surface of the active rotating rod 62. The outer surface of the rotating cylinder 64 is movably connected to the outer surface of the partition 2. An adjusting plate 65 is fixedly installed on the outer surface of the rotating cylinder 64. The adjusting plate 65 is movably connected to the bottom wall of the inner cavity of the screening box 1.

[0048] During use, when the bacterial agent flows into the first screening chamber 11, the tilted position of the adjusting plate 65 fixed on the rotating cylinder 64 causes the bacterial agent to flow into the first screening chamber 11.

[0049] When the bacterial agent flows into the second screening chamber 12, the drive motor 61 fixed on the inverted L-shaped fixed plate 5 is activated. At this time, the output shaft of the drive motor 61 drives the active rotating rod 62 fixed on the output shaft to rotate. The active rotating rod 62 drives the rotating cylinder 64 fixedly sleeved on the active rotating rod 62 to rotate. The rotating cylinder 64 is rotatably connected to the outer surface of the partition plate 2. The rotating cylinder 64 drives the adjusting plate 65 fixed on the rotating cylinder 64 to rotate until the adjusting plate 65 is rotated and adjusted so that the bacterial agent can flow into the second screening chamber 12. During this period, the active rotating rod 62 drives the double groove active wheel 63 fixed on the active rotating rod 62 to rotate. The double groove active wheel 63 drives the screening filter element 7 to rotate, thereby facilitating the adjustment and change of the direction of bacterial agent flow, and thus facilitating the filtration and purification of the bacterial agent.

[0050] The remaining structure is the same as that in Example 1. Example 3

[0051] Reference Figure 1-7 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the upper and lower top walls of the inner cavity of the screening box 1 are provided with second fixing holes 15, and the inner wall of the second fixing hole 15 is fixedly connected to the screening filter element 7.

[0052] The screening filter element 7 includes a belt 71, which is movably connected to a double-groove drive pulley 63. A driven pulley 72 is movably connected to the side of the belt 71 away from the double-groove drive pulley 63. A driven rotating rod 73 is fixedly installed in the inner cavity of the driven rotating rod 72. A second bearing 74 is fixedly sleeved on the outer surface of the driven rotating rod 73. The outer surface of the second bearing 74 is fixedly connected to the inner wall of the second fixing hole 15. An installation cylinder 75 is fixedly sleeved on the outer surface of the driven rotating rod 73. A filter plate 76 is fixedly installed on the outer surface of the installation cylinder 75. The outer surface of the filter plate 76 is movably connected to the striking element 8. The filter plate 76 is movably connected to the chamber walls of the first screening chamber 11 and the second screening chamber 12.

[0053] The top wall of the inner cavity of the screening box 1 is provided with a waist-shaped groove 16, and the inner side wall of the waist-shaped groove 16 is provided with a rotating hole 17. The inner cavity of the rotating hole 17 is movably connected to the striking member 8.

[0054] The striking element 8 includes a rotating shaft 81, which is rotatably connected to the inner cavity of the rotating hole 17. A third bearing 82 is fixedly sleeved on the outer surface of the rotating shaft 81. A connecting rod 83 is fixedly installed on the outer surface of the third bearing 82. A steel ball 84 is fixedly installed at the end of the connecting rod 83 away from the third bearing 82. A striking protrusion 85 is fixedly installed on the outer surface of the steel ball 84. The striking protrusion 85 is movably connected to the outer surface of the filter plate 76.

[0055] During use, when the bacterial agent flows into the first screening chamber 11, the filter plate 76 filters the bacterial agent. The bacterial agent can pass through the filter plate 76 and enter the first screening chamber 11. The bacterial agent is discharged through the inner cavity of the bacterial agent discharge pipe 9. Large molecular impurities in the bacterial agent are filtered by the filter plate 76 and adhere to the filter plate 76. Over time, the filter plate 76 will become clogged, affecting the efficiency of bacterial agent filtration.

[0056] When the filter plate 76 becomes clogged, affecting the filtration efficiency of the microbial agent, the injection of microbial agent into the left-side microbial agent feed pipe 3 is stopped. Then, the rotating double-groove drive wheel 63 drives the belt 71 to rotate, which in turn drives the driven rotating rod 73 to rotate. The driven rotating rod 73 drives the mounting cylinder 75, which is fixedly sleeved on the driven rotating rod 73, to rotate. The mounting cylinder 75 then drives the filter plate 76, which is fixed on the mounting cylinder 75, to rotate until the filter plate 76 is perpendicular to the partition 2 again. Simultaneously, microbial agent is injected into the right-side microbial agent feed pipe 3. At this time, the microbial agent flows into the second screening chamber 12 and is filtered and purified. This cycle is repeated. During this period, the rotating filter plate 76 drives the filter plate fixed on the connecting rod 83 to rotate. The steel ball 84 rotates. When the steel ball 84 detaches from the filter plate 76, the steel ball 84 and the striking protrusion 85 rotate under the action of gravity. The steel ball 84 and the striking protrusion 85 rotate around the rotating shaft 81 and strike the filter plate 76 during the rotation and falling process. The vibration generated by the striking cleans the large molecular impurities on the filter plate 76. The large molecular impurities that detach from the filter plate 76 can be cleaned by the external washing equipment and temporarily discharged through the inner cavity of the bacterial agent discharge pipe 9. The bacterial agent is circulated and purified by alternating the use of the first screening chamber 11 and the second screening chamber 12, which facilitates the cleaning of large molecular impurities on the filter plate 76 and prevents long-term shutdown from affecting the efficiency of the work.

[0057] The remaining structure is the same as that in Example 2. Example 4

[0058] Reference Figure 1-7 The fourth embodiment of the present invention provides a purification method for a microbial agent screening and purification device for organic fertilizer, comprising the following steps: S1, the agent is injected into the inner cavity of the screening box 1 through the inner cavity of the agent feed pipe 3 on the left side, and the tilted position of the adjusting plate 65 causes the agent to flow into the first screening chamber 11. At this time, the impact force of the agent drives the paddle 44 to rotate around the first rotating rod 41 as the axis, and the paddle 44 drives the agent into the first screening chamber 11.

[0059] S2. Based on S1, the bacterial agent flowing into the first screening chamber 11 is screened and filtered by the filter plate 76. At this time, the bacterial agent passes through the filter plate 76 and enters the first screening chamber 11, and is discharged through the bacterial agent discharge pipe 9. However, the large molecular impurities in the bacterial agent adhere to the filter plate 76. Over time, the filter plate 76 will become clogged, affecting the efficiency of bacterial agent filtration.

[0060] S3. Based on S2, when the filter plate 76 is clogged and affects the filtration efficiency of the bacterial agent, the drive motor 61 is started and the injection of bacterial agent into the inner cavity of the left bacterial agent feed pipe 3 is stopped. At this time, the output shaft of the drive motor 61 drives the active rotating rod 62 to rotate. The active rotating rod 62 drives the rotating cylinder 64 and the adjusting plate 65 to rotate until the adjusting plate 65 is tilted so that the bacterial agent flows into the second screening chamber 12. At the same time, the active rotating rod 62 drives the screening filter element 7 to rotate until the filter plate 76 is perpendicular to the partition plate 2. During the rotation, the filter plate 76 drives the knocking element 8 to rotate and knocks the filter plate 76 to generate vibration. The large molecular impurities on the filter plate 76 are dislodged due to the vibration generated by the knocking, so as to clean the large molecular impurities on the filter plate 76. Then, the bacterial agent is injected into the inner cavity of the right bacterial agent feed pipe 3, and the bacterial agent flows into the second screening chamber 12 for filtration and purification.

[0061] S4. Based on S3, the bacterial agent flowing into the second screening chamber 12 generates an impact force that drives the paddle 44 to rotate in the opposite direction around the first rotating rod 41, and the paddle 44 drives the bacterial agent into the second screening chamber 12.

[0062] S5. Based on S4, repeat the steps in S2 and S3 to filter and purify the bacterial agent. Then, use the first screening chamber 11 and the second screening chamber 12 alternately to filter and purify the bacterial agent in a cyclical manner to avoid long-term downtime and affect work efficiency. At the same time, it can clean the large molecular impurities on the filter plate 76.

10. A purification method using a screening and purification device for microbial agents used in organic fertilizers, employing the screening and purification device for microbial agents used in organic fertilizers as described in claim 3, characterized in that: Includes the following steps: S1. The bacterial agent is injected into the inner cavity of the screening box (1) through the inner cavity of the bacterial agent feed pipe (3) on the left side, and the tilted position of the adjusting plate (65) causes the bacterial agent to flow into the first screening chamber (11). At this time, the impact force of the bacterial agent drives the paddle (44) to rotate around the first rotating rod (41) as the axis, and the paddle (44) drives the bacterial agent into the first screening chamber (11). S2. Based on S1, the bacterial agent flowing into the first screening chamber (11) is screened and filtered by the filter plate (76). At this time, the bacterial agent passes through the filter plate (76) and enters the first screening chamber (11), and is discharged through the bacterial agent discharge pipe (9). Meanwhile, the large molecular impurities in the bacterial agent adhere to the filter plate (76). Over time, the filter plate (76) will become clogged, affecting the efficiency of bacterial agent filtration. S3. Based on S2, when the filter plate (76) becomes clogged and affects the filtration efficiency of the microbial agent, the drive motor (61) is started, and the injection of microbial agent into the inner cavity of the left microbial agent feed pipe (3) is stopped. At this time, the output shaft of the drive motor (61) drives the active rotating rod (62) to rotate. The active rotating rod (62) drives the rotating cylinder (64) and the adjusting plate (65) to rotate until the adjusting plate (65) is tilted so that the microbial agent flows into the second screening chamber (12). At the same time, the active rotating rod (62) drives the active rotating rod (62) to rotate. The filter element (7) is rotated until the filter plate (76) is perpendicular to the partition (2). During the rotation, the filter plate (76) drives the striking element (8) to rotate, and the striking element (8) strikes the filter plate (76) to generate vibration. The large molecular impurities on the filter plate (76) are dislodged due to the vibration generated by the striking, so as to clean the large molecular impurities on the filter plate (76). Then, the bacterial agent is injected into the inner cavity of the bacterial agent feed pipe (3) on the right side, and the bacterial agent flows to the second screening chamber (12) for filtration and purification. S4. Based on S3, the bacterial agent flowing into the second screening chamber (12) generates an impact force that drives the paddle (44) to rotate in the opposite direction around the first rotating rod (41), and the paddle (44) drives the bacterial agent into the second screening chamber (12). S5. Based on S4, repeat the steps in S2 and S3 to filter and purify the bacterial agent. Then, use the first screening chamber (11) and the second screening chamber (12) alternately to filter and purify the bacterial agent in a cyclical manner to avoid long-term shutdown and affect work efficiency. At the same time, it can clean the macromolecular impurities on the filter plate (76).
