Description

Technical Field

[0001] The present invention relates to the technical field of organic fertilizer treatment, and specifically to a solid-liquid separation device and separation method for the preparation of biological organic fertilizers. Background Art

[0002] Biological organic fertilizer is a new type of fertilizer that combines the advantages of microbial fertilizers and organic fertilizers. It is mainly made by fermenting and decomposing animal and plant residues through microorganisms, and is rich in a large number of beneficial microorganisms and organic substances. This kind of fertilizer can not only provide comprehensive nutrients for crops, but also improve soil structure, increase soil fertility, enhance the crop's resistance to diseases and pests, promote crop growth, and contribute to environmental protection.

[0003] Publication No. CN113289387A discloses a solid-liquid separation device and its solid-liquid separation method for the preparation of biological organic fertilizers, including a bottom platform. A plurality of support rods are symmetrically and fixedly connected to the bottom side of the bottom platform, and a buffer pad is fixedly connected to the bottom side of each support rod. A plurality of fixed rods are symmetrically and fixedly connected to the upper side of the bottom platform, and a separation box is fixedly connected to the upper ends of the fixed rods. A discharge port is provided on one side of the separation box, and a side door is connected to the discharge port through a hinge. A pressing plate and a filter plate are respectively slidably connected in the separation box, and a plurality of filter holes are formed on the filter plate. The above application moves the pressing plate up and down through a hydraulic telescopic rod, which is convenient for feeding and discharging. When the hydraulic telescopic rod continuously applies pressure, the pressing plate begins to squeeze the raw materials on the upper layer of the filter plate, and under the action of pressure, the liquid in the materials is quickly squeezed out.

[0004] Although the above application and the prior art can accelerate the speed of solid-liquid separation, when the above application and the prior art use a centrifuge to separate the fertilizer from solid to liquid, due to the water content in the biological organic fertilizer, the phenomenon of caking of the biological organic fertilizer will occur. Therefore, the water inside the caked fertilizer cannot be quickly separated, which will reduce the separation efficiency. And after the caked fertilizer is crushed, due to the complexity of the raw materials, the caked fertilizer will contain impurities such as sand and gravel. Therefore, when separating again after crushing, the sand and gravel will rub against the inner wall of the centrifuge, which will affect the service life of the centrifuge. And when the treated raw materials are separated from solid to liquid again, the fertilizer will always accumulate in a certain place, resulting in uneven distribution inside the centrifuge, which will affect the efficiency of solid-liquid separation. Therefore, the present invention proposes a solid-liquid separation device and separation method for the preparation of biological organic fertilizers. Summary of the Invention

[0005] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a solid-liquid separation device and a separation method for the preparation of bio-organic fertilizers, which have the advantages of improving efficiency, preventing impurities, and ensuring uniform distribution, etc., and solve the problems in the above application and the prior art that during the process of solid-liquid separation of fertilizers by using a centrifuge, since the bio-organic fertilizer contains moisture, it will cause the bio-organic fertilizer to agglomerate. As a result, the moisture inside the agglomerated fertilizer cannot be quickly separated, which will reduce the separation efficiency. Moreover, after the agglomerated fertilizer is crushed, due to the complexity of the raw materials, the agglomerated fertilizer will contain impurities such as sand and gravel. Therefore, when the crushed fertilizer is separated again, the sand and gravel will rub against the inner wall of the centrifuge, which will affect the service life of the centrifuge. In addition, when the processed raw materials are re-separated, the fertilizer will always accumulate in a certain place, resulting in uneven distribution inside the centrifuge, which will affect the solid-liquid separation efficiency.

[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a solid-liquid separation device and separation method for preparing biological organic fertilizer, which has the following beneficial effects: 1. The solid-liquid separation device and separation method for preparing biological organic fertilizer, through the coordinated use of the separation component and the anti-sway component, when the driving motor drives the separation filter barrel to rotate through the first driving rod, the centrifugal force generated by the rotation of the separation filter barrel causes the agglomerated raw materials to enter the interior of the collection box through the collection groove, and then fall on the top of the rolling roller, and then the second motor is started, and the second motor drives the rotating rod to rotate through the worm and the worm gear, so that the rotating rod drives the rolling roller to rotate, and then the rolling roller breaks the agglomerated raw materials, so as to avoid the agglomerated raw materials affecting the efficiency of solid-liquid separation, thereby achieving the effect of improving efficiency.

[0017] 2. The solid-liquid separation device and separation method for preparing biological organic fertilizer use an anti-scratch component, and the crushed raw materials fall to the top of the separation plate through the rolling roller, and the third motor is started. The third motor drives the cam to rotate through the fixed rod, so that the cam drives the separation plate to move through the fixed plate. When the fixed plate moves, the fixed plate compresses the spring through the extended tube. When the cam is not in contact with the fixed plate, the spring returns to its initial state and then drives the separation plate to shake back and forth through the fixed plate, thereby causing the raw materials on the top of the separation plate to shake, so that the sand and gravel impurities in the raw materials are screened out, thereby avoiding the friction between the sand and gravel impurities and the inner wall of the separation filter barrel during subsequent separation, thereby achieving the effect of preventing impurities.

[0018] 3. The solid-liquid separation device and separation method for preparing the biological organic fertilizer, when the anti-slosh component, anti-scratch component and dispersion component cooperate, the worm and the fixed rod drive the rotating rod and the auger rod to rotate respectively during the rotation process. The raw materials on the top of the separation plate fall onto the top of the feeding plate due to the sloshing of the separation plate, and then enter the top of the feeding cylinder. As the auger rod moves, the raw materials inside the feeding cylinder are continuously conveyed to the inside of the material distribution plate by the auger rod. When the rotating rod rotates, the rotating rod drives the paddle to rotate, so that the paddle drives the raw materials inside the material distribution plate to move quickly. With the centrifugal force generated by the rotation of the paddle, the raw materials are batch-fed into the separation filter barrel through the feeding slots, thus achieving the effect of uniform distribution.

Then, the raw materials in the storage tank 111 are conveyed into the separation filter barrel 22, so that the separation filter barrel 22 drives the raw materials of the biological organic fertilizer to rotate. The biological organic fertilizer generates centrifugal force through rotation to discharge the liquid inside it through the separation filter barrel 22 into the separation box 11, and then flows into the collection box 1 through the liquid outlet pipe 113; For specific embodiment two, please refer to Figures 1 to 7 , according to a solid-liquid separation device for preparing biological organic fertilizer provided by specific embodiment one, the present embodiment provides a further technical solution: A collection groove 122 is formed on one side of the collection box 121. The anti-slosh component 3 includes a second motor 31 fixedly connected to the top of the collection box 121 and two rotating rods 32 rotatably connected inside the collection box 121. The output end of the second motor 31 is fixedly connected with a worm 311. A worm gear 321 is fixedly connected to the surface of one of the rotating rods 32. The worm gear 321 is in meshing transmission with the worm 311. Crushing rollers 322 are fixedly connected to the surfaces of the two rotating rods 32, and crushing bars are fixedly connected to the surfaces of the crushing rollers 322. The two crushing rollers 322 are in meshing transmission through the crushing bars; When the agglomerated part of the biological organic fertilizer raw material needs to be processed, when the driving motor 21 drives the separation filter barrel 22 to rotate through the first driving rod 211, the separation filter barrel 22 generates centrifugal force through the rotation to make the agglomerated raw materials pass through the collecting tank 122 into the interior of the collecting box 121, and then fall on the top of the rolling roller 322, and then the second motor 31 is started, and the second motor 31 drives the rotating rod 32 to rotate through the worm 311 and the worm gear 321, so that the rotating rod 32 drives the rolling roller 322 to rotate, and then the rolling roller 322 breaks the agglomerated raw materials, thereby preventing the agglomerated raw materials from affecting the effect of subsequent solid-liquid separation; For specific embodiment 3, please refer to Figures 1 to 9 According to the solid-liquid separation device for preparing biological organic fertilizer provided in the second specific embodiment, this embodiment provides a further technical solution: The anti-scratch component 4 includes a third motor 41 fixedly connected to the inside of the collection box 121 and a separation plate 43 slidably connected to the inside of the collection box 121, the separation plate 43 is inclined, the output end of the third motor 41 is fixedly connected to a fixed rod 411, the surface of the fixed rod 411 is fixedly connected to a cam 412, the anti-scratch component 4 also includes a fixed cylinder 42 fixedly connected to the inside of the collection box 121, the inside of the fixed cylinder 42 is slidably connected to a protruding cylinder 421, the inside of the fixed cylinder 42 is fixedly connected to a spring, one end of the protruding cylinder 421 is fixedly connected to a fixed plate 422, the top of the fixed plate 422 is fixedly connected to the bottom of the separation plate 43, and one end of the fixed plate 422 is in contact with the cam 412; It should be noted that a through slot is provided at the bottom of the collection box 121, and a second solenoid valve is provided inside the through slot; When it is necessary to remove the sand and gravel inside the agglomerated raw materials, the crushed raw materials fall to the top of the separation plate 43 through the rolling roller 322, and the third motor 41 is started. The third motor 41 drives the cam 412 to rotate through the fixed rod 411, so that the cam 412 drives the separation plate 43 to move through the fixed plate 422. When the fixed plate 422 moves, the fixed plate 422 compresses the spring through the extended tube 421. When the cam 412 is not in contact with the fixed plate 422, the spring returns to its initial state and drives the separation plate 43 to reciprocate through the fixed plate 422, thereby causing the raw materials on the top of the separation plate 43 to shake, so that the sand and gravel impurities in the raw materials are screened out, thereby avoiding the friction between the sand and gravel impurities and the inner wall of the separation filter barrel 22 during subsequent separation; For specific example 4, please refer to Figures 1 to 13 According to the solid-liquid separation device for preparing biological organic fertilizer provided in the specific embodiment 3, this embodiment provides a further technical solution: The dispersion component 5 includes a first driving sprocket 51 fixedly connected to the surface of the fixed rod 411 and an auger rod 52 rotatably connected inside the collection box 121. A first driven sprocket 521 is fixedly connected to the surface of the auger rod 52. The first driving sprocket 51 and the first driven sprocket 521 are driven by a first chain 511. The dispersion component 5 further includes a feeding cylinder 53 fixedly connected inside the collection box 121. The feeding cylinder 53 is arranged on the surface of the auger rod 52. A feeding plate 531 is fixedly communicated with the surface of the feeding cylinder 53. The feeding plate 531 is inclined. The feeding plate 531 is located at the bottom of the separation plate 43. The dispersion component 5 further includes a second driving sprocket 54 fixedly connected to the surface of the worm 311 and a material distribution plate 55 fixedly connected to the top of the collection box 121. A rotating rod 551 is rotatably connected inside the material distribution plate 55. A plurality of paddles 552 are fixedly connected to the surface of the rotating rod 551. A second driven sprocket 553 is fixedly connected to the surface of the rotating rod 551. The second driving sprocket 54 and the second driven sprocket 553 are driven by a second chain 541. The top of the feeding cylinder 53 is fixedly communicated with the bottom of the material distribution plate 55. A plurality of feeding grooves 554 are formed on the surface of the material distribution plate 55; It should be noted that the control panel 112 is electrically connected to the first solenoid valve, the second solenoid valve, the driving motor 21, the second motor 31 and the third motor 41. The opening and closing of the first solenoid valve, the second solenoid valve, the driving motor 21, the second motor 31 and the third motor 41 are controlled through the operation buttons on the surface of the control panel 112; When it is necessary to separate the crushed raw materials again and avoid their accumulation, the worm 311 and the fixed rod 411 drive the rotating rod 551 and the auger rod 52 to rotate respectively during the rotation process. The raw materials at the top of the separation plate 43 fall on the top of the feeding plate 531 due to the shaking of the separation plate 43, and then enter the top of the feeding cylinder 53. As the auger rod 52 moves, the raw materials inside the feeding cylinder 53 are continuously conveyed to the inside of the material distribution plate 55 through the auger rod 52. When the rotating rod 551 rotates, the rotating rod 551 drives the paddle 552 to rotate, so that the paddle 552 drives the raw materials inside the material distribution plate 55 to move quickly. With the centrifugal force generated by the rotation of the paddle 552, the raw materials are batch-fed into the separation filter barrel 22 through the feeding grooves 554, and then the solid-liquid separation is carried out again through the rotation of the separation filter barrel 22, thereby avoiding the separation efficiency from being reduced due to the raw materials always accumulating at a certain place in the separation filter barrel 22; Specific embodiment five, the present invention also provides a solid-liquid separation method for the preparation of biological organic fertilizer. The solid-liquid separation method for biological organic fertilizer specifically includes the following steps: Step 1: Convey the raw materials to be separated into the separation filter barrel 22, and then start the driving motor 21. The driving motor 21 drives the separation filter barrel 22 to rotate through the first driving rod 211, so that the separation filter barrel 22 separates the solid and liquid of the raw materials; Step 2: When agglomerates appear in the raw materials, the separation filter barrel 22 drives the agglomerated raw materials into the interior of the collection box 121 during high-speed rotation, and the agglomerated raw materials are crushed by the anti-sway component 3; Step 3, the agglomerated raw materials are crushed and fall into the interior of the anti-scratch component 4, so that the anti-scratch component 4 can screen out the sand and stone impurities in the raw materials to prevent the sand and stone impurities from scratching the inner wall of the separation filter barrel 22; Step 4: After the raw materials are screened, they enter the interior of the dispersion component 5, and the dispersion component 5 redistributes the raw materials to various places inside the separation filter barrel 22 to prevent the raw materials from accumulating in a certain place and causing the separation filter barrel 22 to shake violently during rotation.

[0025] Working principle: During use, the raw materials of bio-organic fertilizer that need solid-liquid separation are put into the storage tank 111. When solid-liquid separation of the raw materials of bio-organic fertilizer is required, the drive motor 21 is started. The drive motor 21 drives the separation filter barrel 22 to rotate at a high speed through the first drive rod 211, and then the raw materials in the storage tank 111 are transported to the inside of the separation filter barrel 22, causing the separation filter barrel 22 to drive the raw materials of bio-organic fertilizer to rotate. The bio-organic fertilizer generates centrifugal force through rotation to discharge the liquid inside it through the separation filter barrel 22 into the inside of the separation box 11, and then flows into the collection box 1 through the liquid outlet pipe 113. When it is necessary to process the agglomerated parts in the raw materials of bio-organic fertilizer during the solid-liquid separation process, when the drive motor 21 drives the separation filter barrel 22 to rotate through the first drive rod 211, the centrifugal force generated by the rotation of the separation filter barrel 22 causes the agglomerated raw materials to enter the inside of the collection box 121 through the collection groove 122, and then fall on the top of the rolling roller 322. Then the second motor 31 is started. The second motor 31 drives the rotating rod 32 to rotate through the worm 311 and the worm gear 321, causing the rotating rod 32 to drive the rolling roller 322 to rotate, and thus the rolling roller 322 crushes the agglomerated raw materials, so as to avoid the agglomerated raw materials affecting the subsequent solid-liquid separation effect. When it is necessary to remove the sand and gravel existing inside the agglomerated raw materials, the crushed raw materials fall on the top of the separation plate 43 through the rolling roller 322. The third motor 41 is started. The third motor 41 drives the cam 412 to rotate through the fixed rod 411, causing the cam 412 to drive the separation plate 43 to move through the fixed plate 422. When the fixed plate 422 moves, the fixed plate 422 compresses the spring through the extension cylinder 421. When the cam 412 is not in contact with the fixed plate 422, the spring returns to its initial state and then drives the separation plate 43 to generate reciprocating shaking through the fixed plate 422, thereby causing the raw materials on the top of the separation plate 43 to shake, screening out the sand and gravel impurities in the raw materials, and thus avoiding the friction between the sand and gravel impurities and the inner wall of the separation filter barrel 22 during subsequent separation. When it is necessary to perform solid-liquid separation on the crushed raw materials again and avoid their accumulation, the worm 311 and the fixed rod 411 drive the rotating rod 551 and the auger rod 52 to rotate respectively during the rotation process. The raw materials on the top of the separation plate 43 fall on the top of the feeding plate 531 due to the shaking of the separation plate 43, and then enter the top of the feeding cylinder 53. As the auger rod 52 moves, the raw materials inside the feeding cylinder 53 are continuously transported to the inside of the distribution plate 55 through the auger rod 52. When the rotating rod 551 rotates, the rotating rod 551 drives the paddle 552 to rotate, causing the paddle 552 to drive the raw materials inside the distribution plate 55 to move quickly. With the centrifugal force generated by the rotation of the paddle 552, the raw materials are batch-transported to the inside of the separation filter barrel 22 through the feeding slots 554, and then solid-liquid separation is performed again through the rotation of the separation filter barrel 22, thus avoiding the raw materials always accumulating at a certain place in the separation filter barrel 22 and resulting in a reduction in separation efficiency.
