[0002] Dehydration is a crucial step in the production of microbial organic fertilizers. It directly impacts their subsequent storage, transportation, and performance. Effective dehydration can effectively reduce the fertilizer's moisture content, inhibit excessive microbial growth, mitigate the risk of mold, extend its shelf life, and reduce shipping weight and costs.

[0003] Traditional methods of dehydrating microbial organic fertilizers mostly use centrifugal dehydration, pressurized dehydration or natural drying.

It primarily includes key components such as a mounting plate, a dehydration box, a drying box, a heating plate, a filter plate, and a dehydration mechanism. The bio-organic fertilizer dehydration and drying device disclosed in the aforementioned patent utilizes a booster pump, an elbow, and connecting pipes to achieve pressurized dehydration. However, this structure suffers from the following drawbacks in practical applications: First, the pressure generated by the booster pump is easily unevenly distributed in the dehydration box. The material close to the connecting pipe is fully pressurized, while the material far away from the connecting pipe may not be dehydrated completely, resulting in inconsistent overall dehydration effect. Second, the filter plates of the dehydration box are turned over by the rotating shaft to discharge the materials, and the gaps are prone to residual materials. In addition, there are many dead corners inside the dehydration box and the drying box. Parts need to be disassembled for cleaning, which increases maintenance costs.

DETAILED DESCRIPTION

[0024] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. The specific structure of the present application is shown in Figure 1-Figure 3 .

[0025] Embodiment 1: A dewatering device for microbial organic fertilizer production, comprising an inner cavity 1, a dewatering unit is installed inside the inner cavity 1, a transmission assembly is connected to the bottom of the dewatering unit, the power input end of the transmission assembly extends to the right side outside of the inner cavity 1 and is driven by a matching driving device, the inside of the dewatering unit is used for storing the fertilizer solution to be dewatered, a feed channel 2 for feeding the fertilizer solution into the inside thereof is arranged above the dewatering unit, an on-off component for controlling the on-off thereof is installed at the feed channel 2, and a liquid discharge blocking plug 4 is installed at the left end of the discharge channel 3 in the lower part of the inner cavity 1.

[0026] The external driving device transmits power to the dehydration unit through the transmission assembly, making the dehydration unit operate. The fertilizer solution to be dehydrated enters the dehydration unit through the feed channel 2. Solid-liquid separation is achieved during the operation of the dehydration unit. The separated liquid can be discharged through the discharge channel 3. The drainage seal 4 controls the opening and closing of the discharge channel 3, and the opening and closing component controls the opening and closing of the feed channel 2, thereby completing the dehydration operation of the fertilizer solution.

[0027] On the basis of any of the above technical solutions, further optimization is that: the inner cavity 1 is surrounded by a fixed lower valve body 5 and an upper valve body 6 that is quickly and fixedly connected to the upper part thereof, the connection part between the lower valve body 5 and the upper valve body 6 is sealed, and a feed channel 2 is provided on the upper right side of the upper valve body 6, the inlet of the feed channel 2 is located at the right end, the feed channel 2 is connected to the inner cavity 1 through the feed port 7 located on the lower valve body 5, and the opening and closing component is installed on the top of the feed port 7, and the top of the opening and closing component is screwed through to the top of the lower valve body 5 and connected to the rotating handwheel 8.

[0028] The inner cavity 1 serves as the main frame of the device. Its structure is composed of a fixed lower valve body 5 and an upper valve body 6 connected to it by a quick release method. The connection between the two is sealed to prevent liquid from leaking from the connection during the dehydration process, ensuring that the inner cavity 1 forms a closed space, while facilitating the rapid lifting and disassembly of the upper valve body 6.

[0029] The upper valve body 6 and the lower valve body 5 are quickly disassembled and fixedly connected, which facilitates the disassembly and installation of the equipment and the maintenance of the internal components; the sealing treatment prevents liquid leakage and ensures the sealing of the dehydration process; the position design of the feed channel 2 and the feed port 7 is reasonable, which is conducive to the stable delivery of the fertilizer solution, and the rotating handwheel 8 is easy to operate and can accurately control the opening and closing components; the quick-disassembly structure of the upper valve body 6 and the lower valve body 5 can be quickly separated when collecting the dehydrated fertilizer, which is convenient for cleaning the fertilizer impurities remaining in the inner cavity 1 and the dehydration unit, reducing the cleaning dead corners.

[0030] During operation, the fertilizer solution enters the feed channel 2, located on the right side of the upper valve body 6 and with the inlet located at the right end, through the feed port 7 on the lower valve body 5, and flows into the top inlet of the dehydration unit of the inner cavity 1, thereby delivering the fertilizer solution to the dehydration unit. The opening and closing of the feed port 7 is controlled by the opening and closing component mounted on its top. The opening and closing component is actuated by rotating the handwheel 8. The rotation of the handwheel 8 drives the top of the opening and closing component fixed to it to screw through the lower valve body 5, thereby opening or closing the feed port 7 and regulating the feeding timing of the fertilizer solution.

[0031] On the basis of any of the above technical solutions, further optimization is that: the opening and closing component includes a lifting valve stem 9 screwed into the threaded hole at the top of the lower valve body 5, the top of the lifting valve stem 9 is fixedly connected to the rotating handwheel 8, and the bottom of the lifting valve stem 9 is fixed with an opening and closing valve core 10 for sealing the feed port 7, and when the opening and closing valve core 10 moves downward, it is used to complete the sealing of the feed port 7.

[0032] When the rotary handwheel 8 is rotated by an external force, the lifting valve stem 9 is screwed into the threaded hole at the top of the lower valve body 5, and the top of the lifting valve stem 9 is fixedly connected to the rotary handwheel 8. The rotation of the rotary handwheel 8 will drive the lifting valve stem 9 to move up and down along the axis of the threaded hole. The bottom of the lifting valve stem 9 is fixed with an opening and closing valve core 10, which moves synchronously with the lifting valve stem 9. When the opening and closing valve core 10 moves downward, it can cooperate with the feed port 7 on the lower valve body 5 to achieve the blockage of the feed port 7 and prevent the fertilizer solution from entering the inner cavity 1 through the feed port 7; when the opening and closing valve core 10 moves upward, it separates from the feed port 7, and the feed port 7 is in an open state, allowing the fertilizer solution to enter the inner cavity 1 through the feed port 7. A threaded transmission structure is adopted, that is, the lifting valve stem 9 is screwed into the threaded hole, so that the lifting movement of the lifting valve stem 9 has high precision and stability. By rotating the handwheel 8, the position of the opening and closing valve core 10 can be accurately controlled, and then the opening and closing degree of the feed port 7 can be accurately adjusted, which is convenient for flexible control of the feed amount according to the processing capacity of the dehydration unit.

[0033] The structural design in which the lifting valve stem 9 is fixedly connected to the rotating handwheel 8 and the opening and closing valve core 10 is fixed at the bottom of the lifting valve stem 9 makes the connection between the various components firm, the transmission efficiency is high, and the on-off control of the feed port 7 can be reliably achieved.

[0034] On the basis of any of the above technical solutions, further optimization is that: an oil hole sealing rod 11 is installed in the mounting hole of the lower valve body 5 at the top of the feed channel 2 on the left side of the opening and closing valve core 10, the oil hole sealing rod 11 is screwed and sealed in the mounting hole and an oil sealing plug 12 is fixedly installed at the bottom thereof, the lower end of the oil sealing plug 12 is sealed and extends into the oil pipe cavity 14 of the guide riser part 13 integrally formed in the lower valve body 5, and the top center of the dehydration unit is sealed and movably extends into the oil pipe cavity 14.

[0035] The oil hole blocking rod 11 is screwed and installed in the mounting hole of the lower valve body 5 on the left side of the opening and closing valve core 10, and sealing is achieved through threaded cooperation. The oil sealing plug 12 at its bottom extends to the oil pipe cavity 14 of the guide riser part 13 in the lower valve body 5 and forms a seal; the top center of the dehydration unit extends into the oil pipe cavity 14 in a sealed and movable manner, maintaining the closed state of the oil pipe cavity 14 while ensuring the normal operation of the dehydration unit.

[0036] The screw-on sealing structure of the oil hole sealing rod 11 and the mounting hole is simple and reliable, and is convenient for disassembly and assembly to maintain the oil pipe cavity 14. The oil seal plug 12 further strengthens the sealing of the oil pipe cavity 14. The sealed movable connection between the top of the dehydration unit and the oil pipe cavity 14 does not affect the operation of the dehydration unit, and can prevent the leakage of materials in the oil pipe cavity 14 or the intrusion of external impurities. At the same time, it ensures the stability of the upper part of the entire dehydration unit when it rotates.

[0037] On the basis of any of the above technical solutions, further optimization is that: the dehydration unit includes a vertically arranged sieve drum 15 with a plurality of sieve holes on its surface, the sieve drum 15 is coaxially arranged with the inner cavity 1, and is fixedly connected to the power output end at the top of the transmission assembly at the bottom center of the sieve drum 15, and a storage cavity 16 is provided inside the sieve drum 15, and a constraint shaft 17 is coaxially fixed to the center bottom of the storage cavity 16, and the constraint shaft 17 is sealed and movably extended into the oil pipe cavity 14.

[0038] The sieve drum 15 of the dehydration unit is coaxially arranged with the inner cavity 1 to ensure that the axis of the sieve drum 15 is consistent when rotating, thereby reducing eccentric shaking; the constraint shaft 17 at the center bottom of the storage chamber 16 is sealed and movably extends into the oil pipe chamber 14. The oil pipe chamber 14 forms a radial constraint on the constraint shaft 17 to limit its lateral displacement. At the same time, the constraint shaft 17 is coaxially fixed with the sieve drum 15 and the storage chamber 16, so that the upper part of the sieve drum 15 can obtain stable support through the constraint shaft 17 during rotation, thereby offsetting the centrifugal force interference generated by the rotation.

[0039] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features: On the basis of any of the above technical solutions, further optimization is that a counterweight impeller 18 is coaxially fixed on the outer side wall of the constraint shaft 17 at the bottom of the storage chamber 16, and the counterweight impeller 18 stirs the liquid fertilizer inside the storage chamber 16 when following the rotation.

[0040] The counterweight impeller 18 is coaxially fixed to the outer side wall of the constraint shaft 17 at the bottom of the storage chamber 16. When the constraint shaft 17 rotates along with the screen drum 15 driven by the transmission assembly, the counterweight impeller 18 rotates synchronously. During the rotation, the liquid fertilizer inside the storage chamber 16 is stirred, so that the liquid fertilizer forms a flow state in the storage chamber 16.

[0041] The counterweight impeller 18 is coaxially fixed to the constrained rotating shaft 17 to ensure stability during rotation and avoid additional eccentric vibration; its stirring action can break the static state of the liquid fertilizer in the storage chamber 16, so that the liquid fertilizer contacts the surface of the screen drum 15 more evenly, thereby improving the utilization rate of the screen holes and the dehydration efficiency; at the same time, the setting of the counterweight impeller 18 increases the inertia of the rotating parts, which helps to maintain the smooth rotation of the screen drum 15.

[0042] Further optimization based on any of the above technical solutions is that the transmission assembly includes a gear box 19 fixedly installed in the middle of the discharge channel 3, a horizontally rotating bevel gear 20 is installed in the gear cavity of the gear box 19, the top of the rotating gear shaft 21 of the horizontally rotating bevel gear 20 is movably sealed to above the gear box 19 and is fixedly connected with the top of the screen cylinder 15, a vertical driving bevel gear 22 is engaged on the right side of the horizontally rotating bevel gear 20, and the right end of the driving gear shaft 23 of the vertical driving bevel gear 22 is movably and sealedly penetrated to the outside of the inner cavity 1 and is driven by a matched driving device.

[0043] The gear box 19 of the transmission assembly is fixed in the middle of the discharge channel 3, and the horizontally rotating bevel gear 20 in the internal gear cavity thereof is engaged with the vertical driving bevel gear 22; the driving gear shaft 23 of the vertical driving bevel gear 22 is driven to rotate by the matched driving device, the horizontally rotating bevel gear 20 is driven to rotate through gear engagement transmission, the rotating gear shaft 21 of the horizontally rotating bevel gear 20 is rotated in turn, and the screen cylinder 15 fixedly connected with the top of the rotating gear shaft 21 is synchronously rotated, so that the power is transmitted from the external driving device to the internal screen cylinder 15. Meanwhile, the movable sealing treatment between the rotating gear shaft 21 and the gear box 19 and between the driving gear shaft 23 and the inner cavity 1 ensures the sealing property of the device during transmission.

[0044] The vertical conversion of the power transmission direction can be realized by using the bevel gear engagement transmission, the installation position of the driving device is more flexible, and the overall layout demand of the device is adapted; the gear box 19 provides a closed protection space for the bevel gear, the influence of external dust and liquid on the gear transmission is reduced, and the service life of the assembly is prolonged; the movable sealing structure effectively prevents the liquid in the inner cavity 1 from leaking and the external impurities from invading while ensuring the normal rotation of the gear shaft, and the running stability of the device is improved.

[0045] Further optimization based on any of the above technical solutions is that a gas supply channel 24 connected with the inside of the inner cavity 1 is arranged on the upper valve body 6 on the left side of the feeding channel 2, and the gas supply channel 24 is supplied with gas by an external gas pump device.

[0046] The external gas pump device supplies gas to the inside of the inner cavity 1 through the gas supply channel 24 arranged on the upper valve body 6 on the left side of the feeding channel 2; after the gas enters the inner cavity 1, the gas pressure environment in the inner cavity 1 can be changed, or the gas can be used in cooperation with the dehydration unit for the fertilizer solution to be dehydrated. In addition, the external gas pump device supplies gas to the inside of the inner cavity 1 through the gas supply channel 24 arranged on the upper valve body 6 on the left side of the feeding channel 2, so as to provide the required gas environment for the microorganisms in the inner cavity 1, meet the survival or metabolism demand of the microorganisms, and the gas flow in the cavity can assist the dehydration process.

[0047] The gas supply channel 24 is reasonably positioned, does not interfere with the fertilizer solution transportation of the feed channel 2, and can directly supply gas to the inside of the inner cavity 1, thereby ensuring that the gas can efficiently act on the microorganisms; the gas supply amount and the gas supply rate can be flexibly adjusted through the external gas pump device, thereby adapting to the different gas requirements of different microorganisms.

[0048] The gas flow generated by the gas supply can form a certain scouring effect on the surface of the screen cylinder 15, thereby reducing the adhesion of microorganisms or fertilizer residues on the screen holes and reducing the probability of screen hole blockage; in addition, the gas flow can adjust the temperature distribution inside the inner cavity 1, thereby avoiding that the local temperature is too high or too low to affect the activity of the microorganisms, and indirectly ensuring the quality of the organic fertilizer.

[0049] On the basis of any one of the above technical solutions, further optimization is that the oil pipe cavity 14 is preloaded with lubricating oil for shafts.

[0050] The lubricating oil for shafts preloaded in the oil pipe cavity 14 can form a lubricating effect on the constraint shaft 17 sealed and movably extended into the oil pipe cavity 14, thereby reducing the friction resistance between the constraint shaft 17 and the inner wall of the oil pipe cavity 14 when the constraint shaft 17 rotates with the dehydration unit, and reducing the wear of the components.

[0051] The pre-filled lubricating oil for shafts can ensure that the constraint shaft 17 can be effectively lubricated at the initial stage of operation, and no additional real-time oil supply device is needed, thereby simplifying the structure of the equipment; the characteristics of the lubricating oil for shafts are adapted to the rotation requirements of the constraint shaft 17, thereby maintaining good lubricating effect in long-term use and prolonging the service life of the components.

[0052] The working process of the dehydration device for the microbial organic fertilizer production is as follows: The opening and closing part is opened: the lifting valve rod 9 is driven upward by rotating the hand wheel 8 to make the opening and closing valve core 10 separate from the feed port 7, thereby opening the communication path of the feed channel 2 and the inner cavity 1, and the fertilizer solution to be dehydrated enters the internal storage cavity 16 of the screen cylinder 15 of the dehydration unit through the feed channel 2 and the feed port 7.

[0053] The driving device is started: the driving device drives the horizontal rotating bevel gear 20 to rotate through the vertical driving bevel gear 22 of the transmission assembly, and the rotating gear shaft 21 of the horizontal rotating bevel gear 20 drives the screen cylinder 15 to rotate, and the screen cylinder 15 utilizes the centrifugal force to separate the liquid in the fertilizer solution to the lower part of the inner cavity 1 and the solid material remains in the storage cavity 16 during the rotation process.

[0054] The auxiliary agitation and lubrication: when the screen cylinder 15 rotates, the counterweight impeller 18 at the bottom of the storage cavity 16 rotates synchronously with the constraint shaft 17 to agitate the internal liquid fertilizer, thereby improving the dehydration uniformity; at the same time, the lubricating oil for shafts in the oil pipe cavity 14 plays a lubricating effect on the constraint shaft 17, thereby reducing the rotation friction.

[0055] Gas assistance: An external air pump device delivers gas to the inner cavity 1 through the air supply channel 24, which can not only provide the required gas environment for the microorganisms, but also assist in pushing the separated liquid to flow to the discharge channel 3.

[0056] Drainage operation: Open the drainage seal 4 and the separated liquid is discharged through the discharge channel 3.

[0057] Shutdown and cleaning: After dehydration is completed, turn off the drive equipment and opening and closing components. The upper valve body 6 and the lower valve body 5 can be separated by the quick-disassembly structure to clean and maintain the internal components.
