Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer production, in particular to a dehydration device for producing microbial organic fertilizer and a dehydration method thereof. Background Art

[0002] Microbial organic fertilizer is an organic fertilizer or organic microbial coated fertilizer made from organic solid waste after microbial fermentation, deodorization and complete decomposition. Organic fertilizer is rich in organic matter and nutrients required for crop growth. It can not only provide nutrients required for crop growth and improve soil, but also improve crop quality, increase crop yield, promote high and stable crop yield, maintain soil fertility, and at the same time improve fertilizer utilization and reduce production costs. Common natural fertilizers include green manure, human urine and feces, manure, compost, fermented manure, biogas fertilizer and waste fertilizer. Some microbial organic fertilizers contain too much water and need to be dehydrated before fermentation.

[0003] Generally, after the fertilizer is dehydrated, the dehydrated water needs to be filtered for a second time to remove residual solid particles, suspended matter and organic matter to ensure water purification and environmental protection. However, when the dehydrated water is filtered for the second time, the filtered impurities will accumulate on the filter screen, causing clogging and covering of the filter holes in some areas, which will lead to slower filtration of the dehydrated water and reduce the speed of discharging the dehydrated water. As a result, the dehydrated water will continue to enter the secondary filtration device, causing the dehydrated water to overflow the secondary filtration device, causing pollution to the external environment and low practicality.

[0016] A dehydration method for producing microbial organic fertilizer comprises the following steps:

[0017] S1: After the fertilizer to be dehydrated is added into the feed rack, the motor drives the multi-stage dehydration screw rod to rotate inside the main body, and the fertilizer to be dehydrated that enters the feed rack enters the main body and is squeezed and transmitted forward by the multi-stage dehydration screw rod;

[0018] S2: After the undehydrated fertilizer is transferred to the interior of the dehydration filter cartridge by the multi-stage dehydration screw rod, the fertilizer in the dehydration filter cartridge is dehydrated by the multi-stage dehydration screw rod, and the dehydrated fertilizer is transferred to the end of the main body away from the motor;

[0019] S3: The liquid squeezed out of the fertilizer will be filtered out of the dehydration filter cartridge due to the pressure inside the dehydration filter cartridge. The dehydration filter cartridge and the area of ​​the enhanced protective cartridge are shielded by a covering frame, and the escaping water will pass through the covering frame and the liquid outlet box into the secondary filter frame for secondary filtration;

[0020] S4: The fertilizer accumulates and squeezes at one end of the main body away from the motor, pushing the closed plugging plate to slide on the rotating rod shaft of the multi-stage dehydration spiral rod and compressing the extrusion spring, thereby opening the discharge port of the main body and allowing the dehydrated fertilizer to fall onto the transmission rack below the closed plugging plate for transmission.

[0021] The present invention has the following beneficial effects:

[0022] (1) In the present invention, when the fertilizer pushes the closed plugging plate to slide outward, the sliding rod and the L-shaped fixing frame are driven to move synchronously, thereby driving the secondary filter frame to move as a whole, so that the secondary filter frame slides on the limit slider through the moving hole, and the fertilizer after dehydration in the main body is transmitted. Because the amount of material input each time is different, the amount of dehydrated fertilizer discharged each time is not regular, so the spacing between the closed plugging plate and the main body will also change with the amount of dehydrated fertilizer discharged, so that the secondary filter frame can be continuously driven to slide irregularly on the limit slider, and the secondary filter frame can be shaken as a whole, so that the filtered liquid enters the filter plate for secondary filtration after being discharged through the dehydration filter cartridge, and the filtered impurities accumulated on the filter plate can be moved on the filter plate through the shaking of the secondary filter frame, so as to avoid the impurities from blocking and covering the filter holes in the same area of ​​the filter plate all the time, thereby improving the speed of secondary filtration of the escaping water, and then improving the speed of discharging the escaping water, reducing the phenomenon that the escaping water overflows the secondary filter frame due to continuous entry of the escaping water into the secondary filter frame, and reducing the pollution caused to the external environment.

[0023] (2) After the fertilizer to be dehydrated is added into the feed rack, the motor drives the multi-stage dehydration screw rod to rotate inside the main body, and the fertilizer to be dehydrated that enters the feed rack enters the main body and is extruded and transmitted forward by the multi-stage dehydration screw rod. After the undehydrated fertilizer is transmitted into the dehydration filter cartridge by the multi-stage dehydration screw rod, the fertilizer inside the dehydration filter cartridge is dehydrated by the multi-stage dehydration screw rod, and the dehydrated fertilizer is transmitted to the end of the main body away from the motor. The fertilizer is accumulated and squeezed at the end of the main body away from the motor, and the sealing plate is pushed on the multi-stage dehydration screw rod. The rod slides on the rotating rod shaft and compresses the extrusion spring to open the discharge port of the main body, so that the dehydrated fertilizer falls onto the transmission rack under the closed plugging plate for transmission, and the discharged water will enter the secondary filter rack through the covering frame and the liquid outlet box for secondary filtration. The liquid squeezed out of the fertilizer will be filtered out of the dehydration filter cartridge due to the pressure inside the dehydration filter cartridge. The dehydration filter cartridge and the reinforced protective cylinder area are shielded by the covering frame to reduce the pressure after the pressurized liquid is filtered out of the dehydration filter cartridge. The pressure is too high, resulting in excessive liquid spraying distance and pollution to the external environment, thereby improving the practicability of the device.

[0024] (3) The present invention can avoid continuously filtering large pieces of debris contained in the undehydrated fertilizer by arranging a plurality of tossing rollers inside the feed rack, and prevent large pieces of debris from entering the main body and damaging the multi-stage dehydration spiral rod. When the filter plate moves back and forth continuously, the tooth plate is driven to move synchronously through the extended connecting frame, and the tooth plate is engaged with the plurality of tossing rollers inside the feed rack, so that the plurality of tossing rollers are driven to rotate continuously inside the feed rack, so that when the large pieces of debris on the plurality of tossing rollers partially block the entrance of the feed rack, the tossing rollers are continuously rotated to filter out the large pieces of debris. , driving the debris to change its position continuously, improving the fluidity of the undehydrated fertilizer after entering the feed rack and being transmitted to the inside of the main body, thereby improving the dehydration efficiency of the fertilizer; at the same time, when the tooth plate moves, the double-headed rotating bar will be pushed by the tooth plate, so that the opening and closing angle of the double-headed rotating bar and the tooth plate becomes smaller, and the double-headed rotating bar can be pushed to slide downward inside the lifting slide hole, thereby driving the cleaning scraper to slide on the inner wall of the covering frame, and the liquid on part of the inner wall of the covering frame can be scraped and cleaned, and the lifting slide hole can also be closed by the closing strip.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The multi-stage dehydration screw rod 102 is rotatably connected to the inside of the main body 1, and the rotating rod on the multi-stage dehydration screw rod 102 extends out of the outlet of the main body 1. The multi-stage dehydration screw rod 102 is fixedly connected to the side close to the feeding rack 101 with a motor 103. After the fertilizer to be dehydrated is added into the feeding rack 101, the multi-stage dehydration screw rod 102 is driven by the motor 103 to rotate inside the main body 1, and enters the dehydrated fertilizer inside the feeding rack 101. The fertilizer enters the main body 1 and is squeezed and transported forward by the multi-stage dehydration screw rod 102. After the undehydrated fertilizer is transported to the dehydration filter cartridge 104 by the multi-stage dehydration screw rod 102, the fertilizer in the dehydration filter cartridge 104 is dehydrated by the multi-stage dehydration screw rod 102, and the dehydrated fertilizer is transported to the end of the main body 1 away from the motor 103. The fertilizer is piled up and squeezed at the end of the main body 1 away from the motor 103, and the sealing plate 304 is pushed to slide on the rotating rod shaft of the multi-stage dehydration screw rod 102 and the squeezing spring 305 is compressed to open the discharge port of the main body 1.

[0043] A discharging mechanism 3 is arranged on the left side of the covering frame 201, and the discharging mechanism 3 includes two fixing frames 301, and the two fixing frames 301 are fixedly connected to the left side of the covering frame 201, and the ends of the two fixing frames 301 away from the covering frame 201 are fixedly connected with a rotating baffle 302, and the side of the rotating baffle 302 close to the main body 1 is fixedly connected with an extrusion spring 305, and the end of the extrusion spring 305 away from the rotating baffle 302 is fixedly connected with a closed plugging plate 304, and the side of the closed plugging plate 304 close to the extrusion spring 305 is fixedly connected with two sliding rods 303, and the sides of the two sliding rods 303 away from the closed plugging plate 304 are fixedly connected with an L-shaped fixed The fixed frame 306, the closed plugging plate 304 are against the outlet of the main body 1, the two sliding rods 303 slide through the rotating baffle 302, and the rotating baffle 302 is rotatably connected with the rotating rod extending from the multi-stage dehydration screw rod 102, and the closed plugging plate 304 is slidably connected with the rotating rod extending from the multi-stage dehydration screw rod 102, and the fertilizer is accumulated and squeezed at one end of the main body 1 away from the motor 103, pushing the closed plugging plate 304 to slide on the rotating rod shaft of the multi-stage dehydration screw rod 102 and compressing the squeezing spring 305, so that the discharge port of the main body 1 is opened, so that the dehydrated fertilizer falls onto the transmission frame 6 below the closed plugging plate 304 for transmission;

[0044] The inner wall of the covering frame 201 is provided with a cleaning mechanism 5, which includes two double-headed rotating bars 501, which are respectively rotatably connected to one end of the two tooth plates 405 away from the extension connecting frame 404, and the end of the double-headed rotating bar 501 away from the tooth plate 405 is rotatably connected to a closing bar 502, and the side of the closing bar 502 away from the double-headed rotating bar 501 is fixedly connected to a cleaning scraper 503, and the cleaning scraper 503 is in contact with the inner wall of the covering frame 201, and the connection between the closing bar 502 and the cleaning scraper 503 is in contact with the inner wall of the lifting slide hole 202. The double-headed rotating bar 501 is slidably connected to the upper and lower parts, and the double-headed rotating bar 501 is arranged corresponding to the lifting sliding hole 202. When the tooth plate 405 moves, the double-headed rotating bar 501 is pushed by the tooth plate 405, so that the opening and closing angle of the double-headed rotating bar 501 and the tooth plate 405 becomes smaller, and the double-headed rotating bar 501 can be pushed to slide downward inside the lifting sliding hole 202, thereby driving the cleaning scraper 503 to slide on the inner wall of the covering frame 201, and the liquid on a part of the inner wall of the covering frame 201 can be scraped off and cleaned, and the lifting sliding hole 202 can also be closed by the closing strip 502.

After the undehydrated fertilizer is transmitted to the dehydration filter cartridge 104 by the multi-stage dehydration screw rod 102, the fertilizer located in the dehydration filter cartridge 104 is dehydrated by the multi-stage dehydration screw rod 102, and the dehydrated fertilizer is transmitted to the end of the main body 1 away from the motor 103. The closing plate 304 is pushed by the force of the fertilizer accumulation and extrusion at the end of the main body 1 away from the motor 103. The multi-stage dehydration screw 102 slides on the rotating rod shaft and compresses the extrusion spring 305, and the discharge port of the main body 1 is opened, so that the dehydrated fertilizer falls onto the transmission frame 6 below the closed plugging plate 304 for transmission, and the dehydrated water passes through the covering frame 201 and the liquid outlet box 203 and enters the secondary filter frame 401 for secondary filtration. The liquid squeezed out of the fertilizer will be filtered out of the dehydration filter cartridge 104 due to the pressure. The dehydration filter cartridge 104 and the area of ​​the reinforced protective cylinder 105 are shielded by the covering frame 201 to reduce the pressure of the pressurized liquid after it is filtered out of the dehydration filter cartridge 104. The pressure is too high, resulting in the liquid being sprayed out too far, which may cause pollution to the external environment.

[0047] By arranging a plurality of toggle rollers 406 inside the feed rack 101, it is possible to avoid continuously filtering large pieces of debris contained in the undehydrated fertilizer, and to prevent large pieces of debris from entering the main body 1 and damaging the multi-stage dehydration spiral rod 102. When the filter plate 402 continues to move back and forth, the tooth plate 405 is driven to move synchronously through the extended connecting frame 404. The tooth plate 405 is engaged with the plurality of toggle rollers 406 inside the feed rack 101, and the plurality of toggle rollers 406 are driven to rotate continuously inside the feed rack 101. When the large pieces of debris on the plurality of toggle rollers 406 partially block the entrance of the feed rack 101, the toggle rollers 406 are used to filter out the large pieces of debris. 06 rotates continuously, driving the debris to change its position continuously, thereby improving the fluidity of the undehydrated fertilizer after entering the feed rack 101 and being transmitted to the inside of the main body 1. At the same time, when the tooth plate 405 moves, the double-headed rotating bar 501 is pushed through the tooth plate 405, so that the opening and closing angle of the double-headed rotating bar 501 and the tooth plate 405 becomes smaller, and the double-headed rotating bar 501 can be pushed to slide downward inside the lifting slide hole 202, thereby driving the cleaning scraper 503 to slide on the inner wall of the covering frame 201, and the liquid on a part of the inner wall of the covering frame 201 can be scraped and cleaned, and the lifting slide hole 202 can also be closed by the closing strip 502.

[0050] S2: After the undehydrated fertilizer is transferred to the interior of the dehydration filter cartridge 104 by the multi-stage dehydration screw rod 102, the fertilizer in the dehydration filter cartridge 104 is dehydrated by the multi-stage dehydration screw rod 102, and the dehydrated fertilizer is transferred to the end of the main body 1 away from the motor 103;

[0051] S3: The liquid squeezed out of the fertilizer will be filtered out of the dehydration filter cartridge 104 due to the pressure inside the dehydration filter cartridge 104, and the dehydration filter cartridge 104 and the area of ​​the reinforced protective cartridge 105 are shielded by the covering frame 201, and the escaping water will enter the secondary filter frame 401 through the covering frame 201 and the liquid outlet box 203 for secondary filtration;

[0052] S4: The force of the fertilizer accumulation and squeezing at one end of the main body 1 away from the motor 103 pushes the closed plugging plate 304 to slide on the rotating shaft of the multi-stage dehydration screw rod 102 and compresses the squeezing spring 305, thereby opening the discharge port of the main body 1 and allowing the dehydrated fertilizer to fall onto the transmission rack 6 below the closed plugging plate 304 for transmission.
