Description

Technical Field

[0001] This invention relates to the field of organic fertilizer processing technology, and more specifically, to an organic compound fertilizer granulation equipment and its usage method. Background Technology

[0002] Organic compound fertilizer is a type of fertilizer made by mixing organic fertilizers with inorganic fertilizers or a variety of organic fertilizers, designed to provide a comprehensive and balanced supply of nutrients. It combines the long-lasting effects and soil-improving advantages of organic fertilizers with the rapid effects and high nutrient content of inorganic fertilizers.

[0003] In common organic compound fertilizer granulation equipment, screen plates are often used, which can lead to screen blockage. The common solution is to unclog the screen plates. However, because fertilizers have a certain level of moisture and viscosity, they tend to stick to the screen plates during the screening process. Traditional solutions that only unclog the screen plates are not effective in removing the fertilizer from them. Therefore, it is necessary to design an organic compound fertilizer granulation equipment to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an organic compound fertilizer granulation device and its usage method to solve the problems mentioned in the background art.

The honeycomb roller is located at the uppermost end of the inner cavity of the preparation box, and the crushing and stirring device is located below the honeycomb roller. A braking device is located below the crushing and stirring device. A symmetrical sieve frame device is connected to the bottom of the inner cavity of the preparation box, and a sieve plate is connected to the sieve frame device. Anti-blocking devices are connected to the left and right sides of the preparation box near the bottom, and a collection box is connected to the bottom of the preparation box.

[0006] Preferably, the sieve frame device includes a frame, a rotating shaft is provided on the back of the frame, a sliding groove is provided on one side of the frame, an automatic paddle is provided next to the sliding groove, the automatic paddle is fixedly installed on the upper surface of the frame, a connecting groove is provided on the frame, the sieve plate is connected in the connecting groove, and a scraper is provided at the tail end of the connecting groove. An electromagnet is provided inside the scraper, connecting holes are provided on both sides of the scraper, and a sensing limit block is connected to the scraper through the connecting holes. The sensing limit block is fixedly installed on the frame, and a pressure sensor is installed on the sensing limit block. An open connecting post is fixedly provided on the back of the scraper.

[0007] Preferably, the sieve plate includes a plate surface fixedly connected in the connecting groove, a return spring fixedly connected to the tail of the plate surface, the return spring fixedly connected to the innermost end of the connecting groove, filter strips provided on the plate surface, and a lever fixedly connected to the plate surface, the lever being located in the sliding groove and at the same horizontal level as the automatic lever.

[0008] Preferably, the preparation box includes a box body, a feeding port is provided at the top of the box body, a rectangular groove is provided at the bottom of the box body, strip-shaped channels are provided on both sides of the box body, and limit sliding rods are fixedly provided on the front and rear sides of the box body. The limit sliding rods are connected to the anti-blocking device, and a limit telescopic rod is fixedly provided on the back of the box body.

[0009] Preferably, the braking device includes braking power supplies fixedly installed at the four corners inside the preparation box. The lower end of each braking power supply is connected to a lifting rod, and the bottom end of the lifting rod is provided with a hexagonal connecting nail. A feeding channel is fixedly connected between the four braking power supplies.

[0010] Preferably, the rotating shaft passes through the preparation box and is externally connected to a drive motor. The drive motor is fixedly installed on the outer surface of the preparation box. A drive gear is connected to the drive motor. The drive gear is connected to the anti-blocking device and is located outside the preparation box. A battery is provided on the back of the scraper.

[0011] Preferably, the anti-blocking device includes a block with a strip-shaped insert plate on it, and L-shaped moving arms fixedly connected to both sides of the block. A strip gear is provided on the upper surface of the long end of the L-shaped moving arm, and a driven gear is meshed on the strip gear. The driven gear is movably connected to the front and rear of the preparation box, and the driven gear meshes with the driving gear. A strip groove is formed on the inner surface of the long end of the L-shaped moving arm. A free telescopic rod is fixedly connected to the block, and the other end of the free telescopic rod is fixedly connected to the side of the preparation box.

[0012] Preferably, a method for granulating organic compound fertilizer includes the following steps:

[0013] S1. Feeding and crushing: The fertilizer is fed into the preparation box through the feeding port. After being crushed by the honeycomb rollers and crushed again by the crushing and mixing device, the fertilizer will fall into countless particles and fall onto the screen plate connected to the screen frame device through the feeding channel.

[0014] S2. Screening: At this time, the limit telescopic rod penetrates through the back of the box and is inserted into the side of the frame to limit and fix the frame. The automatic paddle rotates and can regularly paddle the lever to make the screen plate vibrate back and forth, so that the fertilizer particles on the screen plate are continuously filtered and fall into the collection box to achieve particle screening.

[0015] S3, Secondary Collection: After the initial screening, larger particles will remain on the sieve plate, and particles will be stuck in the filter strip. At this time, the frame will be rotated by the drive motor, so that the large particles that are not filtered on the sieve plate will fall into the collection box that has been prepared in advance.

[0016] S4. Cleaning the screen plate: When the screen frame device rotates downwards by 90°, the perforated connecting column is directly opposite the lifting rod, and the hexagonal connecting nail is connected to the magnetic perforated connecting column. Then, the lifting rod is driven, which moves the scraper up and down along the front surface of the screen plate to scrape off the particles remaining on the surface of the screen plate. At the same time, when the drive motor drives the frame to rotate as a whole, the drive gear drives the driven gear to rotate, which in turn drives the strip plate on the L-shaped moving arm connecting block to insert into the strip channel. When the frame rotates to be parallel to the left and right sides, the strip plate just passes through the strip channel and inserts into the filter strip on the plate, thereby clearing the filter strip on the screen plate and effectively further improving the fineness of fertilizer granulation screening.

[0017] Compared with the prior art, the advantages of this invention are:

[0018] (1) In this invention, not only is a dredging structure designed for the sieve plate, but a scraper is also designed to clean the surface of the sieve plate, which effectively further improves the precision of fertilizer granulation screening.

[0019] (2) In this invention, there is a linkage between the two structures of unblocking and cleaning. When the screen frame device rotates down 90°, the open connecting column is directly opposite the lifting rod, and the hexagonal connecting nail is connected to the magnetic open connecting column. Then the lifting rod is driven to move the scraper up and down along the front surface of the screen plate to scrape off the particles remaining on the surface of the screen plate. At the same time, when the drive motor drives the frame to rotate as a whole, the active gear drives the driven gear to rotate, and then drives the strip plate on the L-shaped moving arm connecting block to insert into the strip channel. When the frame rotates to be parallel to the left and right sides, the strip plate just passes through the strip channel and is inserted into the filter strip on the plate surface to unblock the filter strip on the screen plate.

[0020] (3) In this invention, the screen plate is designed to be movable. The automatic paddle can regularly paddle the lever, causing the screen plate to vibrate back and forth, so that the fertilizer particles on the screen plate are continuously filtered and fall into the collection box, thus achieving particle screening. The frame is rotated as a whole by driving the motor, so that the large particles that are not filtered on the screen plate fall into the collection box that has been replaced in advance.

[0034] Please see Figure 1 - Figure 9 As shown, an organic compound fertilizer granulation device includes a preparation box 1, a honeycomb roller 2, and a crushing and stirring device 3. The honeycomb roller 2 is located at the uppermost end of the inner cavity of the preparation box 1, and the crushing and stirring device 3 is located below the honeycomb roller 2. A braking device 4 is located below the crushing and stirring device 3. A symmetrical screen frame device 5 is connected to the inner cavity of the preparation box 1 near the bottom.

A pressure sensor 509 is installed on the 505. A perforated connecting post 5011 is fixedly installed on the back of the scraper 504. The scraper 504 is close to the front surface of the screen plate 6. A pressure sensing head is installed inside the perforated connecting post 5011. When the hexagonal connecting nail 404 is inserted into the perforated connecting post 5011 and presses its internal pressure sensing head, and the sensing limit block 505 is normally inserted into the scraper 504, the electromagnet inside the scraper 504 is disconnected, triggering the sensing limit block 505 to retract, the electromagnet is reconnected, and the perforated connecting post 5011 is re-magnetized, so that the perforated connecting post 5011 and the hexagonal connecting nail 404 are firmly connected.

[0036] refer to Figure 8 The sieve plate 6 includes a plate surface 601 fixedly connected in the connecting groove 502. A return spring 604 is fixedly connected to the tail of the plate surface 601. The return spring 604 is fixedly connected to the innermost end of the connecting groove 502. The plate surface 601 has filter strips 602, and a lever 603 is fixedly connected to the plate surface 601. The lever 603 is located in the sliding groove and is at the same horizontal line as the automatic lever 503. The automatic lever 503 is controlled to rotate. The automatic lever 503 can regularly move the lever 603, causing the sieve plate 6 to vibrate back and forth, so that the fertilizer particles on the sieve plate 6 are continuously filtered and fall into the collection box 8, thereby realizing particle screening.

[0037] refer to Figure 4 The preparation box 1 includes a box body 101. A feeding port 102 is provided on the top of the box body 101. A rectangular groove 103 is provided on the bottom of the box body 101. Strip channels 104 are provided on both sides of the box body 101. Limiting slide rods 105 are fixedly provided on the front and back sides of the box body 101. The limiting slide rods 105 are connected to anti-blocking devices 7. A limiting telescopic rod 106 is fixedly provided on the back of the box body 101. A strip-shaped insert plate 702 can pass through the strip channel 104. The limiting slide rod 105 is used to connect to the strip channel 707. The rod body of the limiting telescopic rod 106 passes through the back of the box body 101 and is inserted into the side of the frame 501 to limit and fix the frame 501.

[0038] refer to Figure 5The braking device 4 includes braking power supplies 401 fixedly installed at the four corners inside the preparation box 1. The lower end of the braking power supply 401 is connected to a lifting rod 403. The bottom end of the lifting rod 403 is provided with a hexagonal connecting nail 404. The four braking power supplies 401 are fixedly connected to a feeding channel 402. When the screen frame device 5 rotates downward 90°, the perforated connecting post 5011 is directly opposite the lifting rod 403. The hexagonal connecting nail 404 is made of iron and can be connected to the magnetic perforated connecting post 5011. Then, the lifting rod 403 is driven to move the scraper 504 up and down along the front surface of the screen plate 6 to scrape off the particles remaining on the surface of the screen plate 6.

[0039] refer to Figure 6 and Figure 7 A rotating shaft 508 passes through the preparation box 1 and is externally connected to a drive motor 506. The drive motor 506 is fixedly installed on the outer surface of the preparation box 1. A drive gear 507 is connected to the drive motor 506. The drive gear 507 is connected to an anti-clogging device 7 and is located outside the preparation box 1. A battery 5010 is provided on the back of the scraper 504. The battery 5010 on the back of the scraper 504 is used to provide power to the electromagnet inside the scraper 504. The drive motor 506 enables the frame 501 to rotate as a whole, so that large unfiltered particles on the sieve plate 6 fall into the pre-prepared collection box 8. After the frame 501 rotates with the sieve plate 6, the filter strips 602 on the sieve plate 6 are aligned with the strip channel 104, which facilitates the subsequent unblocking of the sieve plate 6.

[0040] refer to Figure 9 The anti-blocking device 7 includes a block 701, on which a strip-shaped insert 702 is provided. L-shaped movable arms 703 are fixedly connected to both sides of the block 701. A strip gear 704 is provided on the upper surface of the long end of the L-shaped movable arm 703. A driven gear 706 is meshed on the strip gear 704. The driven gear 706 is movably connected to the front and rear of the preparation box 1, and meshes with the driving gear 507. A strip groove 707 is formed on the inner surface of the long end of the L-shaped movable arm 703. A free telescopic rod 705 is fixedly connected to the block 701. The other end of 705 is fixedly connected to the side of the preparation box 1. When the drive motor 506 drives the frame 501 to rotate as a whole, the drive gear 507 drives the driven gear 706 to rotate, which in turn drives the L-shaped moving arm 703 to connect the strip plate 702 on the block 701 to insert into the strip channel 104. When the frame 501 rotates to be parallel to the left and right sides, the strip plate 702 just passes through the strip channel 104 and is inserted into the filter strip 602 on the plate surface 601, thereby clearing the filter strip 602 on the sieve plate 6 and effectively further improving the fineness of fertilizer granulation screening.

[0041] One method for granulating organic compound fertilizer includes the following steps:

[0042] S1. Feeding and crushing: The fertilizer is fed into the box 101 of the preparation box 1 through the feeding port 102. After being crushed by the honeycomb roller 2 and crushed again by the crushing and mixing device 3, the fertilizer will fall into countless particles and fall onto the screen plate 6 connected to the screen frame device 5 through the feeding channel 402.

[0043] S2. Screening: At this time, the body of the limiting telescopic rod 106 passes through the back of the box 101 and is inserted into the side of the frame 501 to limit and fix the frame 501. The automatic paddle 503 is controlled to rotate. The automatic paddle 503 can regularly paddle the paddle 603, causing the screen plate 6 to vibrate back and forth, so that the fertilizer particles on the screen plate 6 are continuously filtered and fall into the collection box 8, thus realizing particle screening.

[0044] S3. Secondary collection: After the initial screening, larger particles will remain on the sieve plate 6, and particles will be stuck in the filter strip 602. At this time, the frame 501 will be rotated as a whole by the drive motor 506, so that the large unfiltered particles on the sieve plate 6 will fall into the collection box 8 that has been replaced in advance.

[0045] S4. Cleaning the screen plate: When the screen frame device 5 rotates downwards by 90°, the perforated connecting post 5011 is directly opposite the lifting rod 403, and the hexagonal connecting nail 404 is connected to the magnetic perforated connecting post 5011. Then, the lifting rod 403 is driven to move the scraper 504 up and down along the front surface of the screen plate 6 to scrape off the particles remaining on the surface of the screen plate 6. At the same time, when the drive motor 506 drives the frame 501 to rotate as a whole, the drive gear 507 drives the driven gear 706 to rotate, which in turn drives the strip plate 702 on the L-shaped moving arm 703 connected to the block 701 to insert into the strip channel 104. When the frame 501 rotates to be parallel to the left and right sides, the strip plate 702 just passes through the strip channel 104 and is inserted into the filter strip 602 on the plate surface 601, thereby clearing the filter strip 602 on the screen plate 6 and effectively improving the fineness of fertilizer granulation screening.
