Description

Technical Field

[0001] This utility model relates to the field of fertilizer production and processing technology, specifically to a granulation device for fertilizer production and processing. Background Technology

[0002] Fertilizer is an important agricultural material that can increase crop yields and improve soil quality. The production process of fertilizer involves multiple steps, the most basic of which is converting raw materials into usable nutrients. The main raw materials for fertilizer include elements such as nitrogen, phosphorus, and potassium, which are typically extracted from resources such as natural gas, ores, and phosphate rocks. The fertilizer production process generally consists of three main steps: raw material processing, reaction, and finishing.

[0003] For example, the authorization announcement number "CN218501971U" describes a granulation device for fertilizer production and processing. This device uses two push plates to simultaneously push two fixed blocks and the granulation plate upwards, allowing the entire granulation plate to be removed for subsequent cleaning. However, existing granulation devices for fertilizer production and processing use hydraulic extrusion to force fertilizer into granulation holes. The granulation plate outside the holes rotates with the motor drive, causing the fertilizer raw material to be subjected to lateral rotational and torsional forces during downward extrusion. Therefore, the resulting fertilizer granules are twisted, elongated strips, rather than uniformly sized granules, thus reducing the quality of the granulated product.

[0004] Meanwhile, existing fertilizer granulation equipment requires soft and malleable fertilizer as a prerequisite for granulation. Therefore, the fertilizer raw material needs to be soft and have strong binding force. As a result, the fertilizer granules are still in a soft and deformable state for a short time after extrusion and need to be dried, cooled and shaped before they can be taken out. Therefore, the process of waiting for the fertilizer granules to naturally shape and air dry is relatively long, which greatly affects the subsequent fertilizer granulation production operation and reduces the working efficiency of the fertilizer granulation equipment. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of poor fertilizer pellet forming quality and low working efficiency of existing fertilizer granulation devices used in fertilizer production and processing, and to propose a fertilizer granulation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a granulation device for fertilizer production and processing, including a base, a support plate, and a granulation box. The support plate is fixedly installed on the top of the base, and the granulation box is fixedly installed above the support plate. The inner side of the granulation box is provided with a fertilizer production extrusion discharge structure, the inner side of the support plate is provided with a fertilizer production scraping granulation uniform structure, the inner side of the granulation box is provided with a fertilizer granulation raw material addition extrusion structure, and the two sides of the support plate are provided with fertilizer granule rapid air drying structures.

[0008] Preferably, the fertilizer production extrusion discharge structure includes a positioning tube and a forming plate. The positioning tube is fixedly installed on the inner wall of the granulation box, and the forming plate is fixedly connected to the inner side of the positioning tube. Multiple shaping holes are fixedly opened on the inner side of the forming plate, and a sliding baffle is fixedly sleeved on the inner wall of the positioning tube.

[0009] Preferably, the fertilizer production scraping granulation uniform structure includes a motor and a receiving hopper. The motor is fixedly connected to the upper inner side of the support plate. A scraping rod is fixedly connected to the top of the motor's output shaft. The receiving hopper is fixedly sleeved on the outer wall of the motor's output shaft. Two material picking plates are rotatably connected to the side wall of the receiving hopper via pins. Two screws are threadedly connected to the top of the two material picking plates. The ends of the two screws are threadedly connected to the inner side of the top edge of the receiving hopper. The top of the scraping rod is rotatably pressed against the bottom surface of the forming plate.

[0010] Preferably, the fertilizer granulation raw material addition extrusion structure includes a feeding trough and a hydraulic cylinder. The two feeding troughs are fixedly connected to both sides of the outer wall of the granulation box, and the top of the two feeding troughs is movably connected to a cover plate. The two hydraulic cylinders are fixedly installed on the top of the granulation box, and the lower end of the two hydraulic cylinders is fixedly connected to an extrusion plate. The bottom end of the extrusion plate is fixedly connected to a plurality of extrusion heads.

[0011] Preferably, the rapid air-drying structure for fertilizer granules includes slotted holes and blowers. Two slotted holes are fixedly opened on the two side walls of the support plate, and two blowers are fixedly installed inside the two slotted holes. One end of each blower is fixedly connected to an air inlet pipe, and the other end of each blower is fixedly installed with a blower head.

[0012] Preferably, a maintenance door is rotatably connected to the front end of the outer wall of the granulation box via a pin, and an insulation layer is fixedly connected to the inner wall of the granulation box.

[0013] The present invention discloses a granulation device for fertilizer production and processing, which has the following advantages: the motor output shaft can simultaneously drive the scraper rod and the receiving hopper to rotate. The scraper rod periodically scrapes off the fertilizer strips extruded from below the forming plate. The scraped fertilizer segments fall into the inner side of the receiving hopper for storage. As the receiving hopper also rotates continuously, the bucket-shaped receiving hopper can shake the fertilizer granules into uniformly sized granules. The scraping and shaking combined with the shaking result in a more uniform structure of fertilizer granules, effectively improving the granulation quality of the granulation device for fertilizer production and processing.

[0014] The slotted holes facilitate manual material handling. The blower uses a motor to drive a fan to generate airflow. After the blower is connected to the power supply and started, the airflow drawn in through the air inlet pipe is blown vertically upwards along the upper blower head. The airflow can then pass through the holes below the receiving hopper to quickly shape the granulated fertilizer. In this way, the final shaped fertilizer does not need to wait for the cooling and drying process, and can be quickly handled, which facilitates subsequent fertilizer production and improves the working efficiency of the granulation equipment used for fertilizer production and processing.

[0022] The present invention will be further described below with reference to the accompanying drawings: Example

[0023] Please see Figure 1-6 In this embodiment, a granulation device for fertilizer production and processing includes a base 1, a support plate 2, and a granulation box 3. The support plate 2 is fixedly installed on the top of the base 1. Both the support plate 2 and the base 1 are welded from stainless steel, which has high strength and compressive strength. The granulation box 3 is fixedly installed above the support plate 2. The inner side of the granulation box 3 can be used as a space for fertilizer production extrusion granulation. The inner side of the granulation box 3 is provided with a fertilizer production extrusion discharge structure 5. The inner side of the support plate 2 is provided with a fertilizer production scraping granulation uniform structure 6. The inner side of the granulation box 3 is provided with a fertilizer granulation raw material addition extrusion structure 7. The two sides of the support plate 2 are provided with a fertilizer granule rapid drying structure 8.

[0024] The fertilizer production extrusion discharge structure 5 includes a positioning tube 51 and a forming plate 53. The positioning tube 51 is fixedly installed on the inner wall of the granulation box 3. The inner diameter of the positioning tube 51 and the sliding baffle 52 is slightly larger than the diameter of the extrusion plate 74. The extrusion plate 74 is pushed downward into the positioning tube 51 by the hydraulic cylinder 73, which extrudes the fertilizer production raw material that falls into the positioning tube 51 downward. The forming plate 53 is fixedly connected to the inner side of the positioning tube 51. Multiple shaping holes 54 are fixedly opened on the inner side of the forming plate 53. After the fertilizer raw material is subjected to the extrusion pressure, it will be extruded along the multiple shaping holes 54 opened inside the forming plate 53. The extruded fertilizer raw material will form long strips of uniform thickness. The sliding baffle 52 is fixedly sleeved on the inner wall of the positioning tube 51.

[0025] The fertilizer production scraping granulation uniform structure 6 includes a motor 61 and a receiving hopper 62. The motor 61 is fixedly connected to the upper inner side of the support plate 2. The motor 61 is a servo motor, and a motor model that meets the usage requirements can be selected. A scraping rod 65 is fixedly connected to the top of the output shaft of the motor 61. The scraping rod 65 is a rectangular horizontal long rod made of aluminum alloy. The top of the scraping rod 65 is close to the lower end face of the extrusion plate 74. The receiving hopper 62 is fixedly sleeved on the outer wall of the output shaft of the motor 61. The receiving hopper 62 is made of stainless steel mesh frame and welded to the outside of the output shaft of the motor 61. When the power is connected and the motor 61 is started, the output shaft of the motor 61 can simultaneously drive the scraping rod 65 and the receiving hopper 62 to rotate. The scraping rod 65 cycles... The fertilizer strips extruded from below the forming plate 53 are scraped off and fall into the inner side of the receiving hopper 62 for storage. As the receiving hopper 62 rotates continuously, the bucket-shaped receiving hopper 62 shakes the fertilizer granules into uniformly sized granules. The side wall of the receiving hopper 62 is rotatably connected to two picking plates 63 by a pin. The top of the two picking plates 63 is threaded with two screws 64. Finally, the motor 61 stops working, and the operator manually unscrews the screws 64 through the slotted holes 81 on both sides. The picking plates 63 flip down and open, discharging the fertilizer production granules formed inside the receiving hopper 62. The ends of the two screws 64 are threaded to the inner side of the top edge of the receiving hopper 62, and the top of the scraping rod 65 rotates and adheres tightly to the bottom surface of the forming plate 53.

[0026] The scraper rod 65 is a rectangular horizontal long rod made of aluminum alloy. The top of the scraper rod 65 is close to the lower end face of the extrusion plate 74. The receiving hopper 62 is made of stainless steel mesh frame and welded to the outside of the output shaft of the motor 61. When the power is connected and the motor 61 is started, the output shaft of the motor 61 can drive the scraper rod 65 and the receiving hopper 62 to rotate at the same time. The scraper rod 65 periodically scrapes off the fertilizer strips extruded from below the forming plate 53. The scraped fertilizer segments will fall into the inside of the receiving hopper 62 for storage. As the receiving hopper 62 also rotates continuously, the bucket-shaped receiving hopper 62 can shake the fertilizer granules into uniformly sized granules. Finally, the motor 61 is stopped, and the operator manually unscrews the screws 64 through the slotted holes 81 on both sides. The material receiving plate 63 flips down and opens, discharging the fertilizer production granules formed inside the receiving hopper 62. The scraping and shaking structure makes the fertilizer granules more uniform, effectively improving the granulation quality of the granulation device used for fertilizer production and processing.

[0027] The fertilizer granulation raw material addition extrusion structure 7 includes a feeding trough 71 and a hydraulic cylinder 73. Two feeding troughs 71 are fixedly connected to both sides of the outer wall of the granulation box 3. The feeding troughs 71 are downward-sloping stainless steel pipes. The operator can manually open the upper cover plate 72 and then pour the prepared fertilizer granulation raw material into the feeding trough 71. The top of the two feeding troughs 71 is movably connected to the cover plate 72. Two hydraulic cylinders 73 are fixedly installed at the top of the granulation box 3. The hydraulic cylinders 73 use hydraulic power to push the transverse extrusion plate 74 downward. The hydraulic cylinders 73 push the extrusion plate 74 to extrude the fertilizer raw material downward on the forming plate 53. The lower end of the two hydraulic cylinders 73 is fixedly connected to the extrusion plate 74. The number and distribution position of the extrusion heads 75 correspond to the shaping holes 54, which facilitates the extrusion of fertilizer that is blocked in the shaping holes 54 to save raw materials. Multiple extrusion heads 75 are fixedly connected to the bottom end of the extrusion plate 74.

[0028] The rapid air-drying structure 8 for fertilizer granules includes slotted holes 81 and blowers 82. The two slotted holes 81 are fixedly opened on the two side walls of the support plate 2. The slotted holes 81 facilitate manual operation for material removal. The two blowers 82 are fixedly installed inside the two slotted holes 81. The blowers 82 are a relatively mature technology at present. The blowers 82 use a motor to drive a fan to generate air force. After the blowers 82 are connected to the power supply and started, the air force drawn in by the air inlet pipe 83 is blown vertically upward along the upper blower head 84. Then the air force can blow the granular fertilizer through the holes below the receiving hopper 62 to quickly shape the fertilizer granules. One end of the two blowers 82 is fixedly connected to the air inlet pipe 83, and the other end of the two blowers 82 is fixedly installed with the blower head 84.

[0029] The slotted hole 81 facilitates manual material handling. The blower 82 uses a motor to drive a fan to generate airflow. After the blower 82 is connected to the power supply and started, the airflow drawn in by the air inlet pipe 83 is blown vertically upward along the blower head 84. The airflow can then pass through the holes below the receiving hopper 62 to quickly shape the granulated fertilizer. In this way, the final shaped fertilizer does not need to wait for the cooling and drying process and can be quickly handled, which facilitates subsequent fertilizer production and improves the working efficiency of the granulation device used for fertilizer production and processing.

[0030] The front end of the outer wall of the pelleting box 3 is connected to a maintenance door 4 by a pin. The maintenance door 4 can be manually opened by flipping it outward, which makes it convenient for staff to clean the forming plate 63 and maintain the hydraulic cylinder 73. The inner wall of the pelleting box 3 is fixedly connected to an insulation layer. The insulation layer is a smooth electric heating plate that can generate heat when the circuit is turned on, ensuring that the fertilizer raw material can maintain a certain degree of softness and plasticity during the extrusion process.

[0031] Working principle:

[0032] Granulation equipment used in fertilizer production and processing is used to manufacture uniformly sized granules from well-mixed fertilizer raw materials in fertilizer production, making them easy to package and store. The fertilizer production process is usually divided into three main steps: raw material processing, reaction, and processing.

[0033] The feeding hydraulic cylinder extrusion structure of the granulation device used in fertilizer production and processing:

[0034] The feeding trough 71 is a downward-sloping stainless steel pipe. The operator can manually open the upper cover plate 72 and pour the prepared fertilizer granulation raw materials into the feeding trough 71. The tops of the two feeding troughs 71 are movably connected to the cover plate 72. Two hydraulic cylinders 73 are fixedly installed at the top of the granulation box 3. The hydraulic cylinders 73 use hydraulic power to push the transverse extrusion plate 74 downward. The hydraulic cylinders 73 push the extrusion plate 74 to squeeze the fertilizer raw materials downward on the forming plate 53. The lower ends of the two hydraulic cylinders 73 are fixedly connected to the extrusion plate 74. The number and distribution of the extrusion heads 75 correspond to the shaping holes 54, which facilitates the extrusion of fertilizer materials that are blocked in the shaping holes 54, saving raw materials.

[0035] Extrusion discharge structure of granulation equipment used in fertilizer production and processing:

[0036] The inner diameter of the positioning tube 51 and the sliding baffle 52 is slightly larger than the diameter of the extrusion plate 74. The extrusion plate 74 is pushed down into the positioning tube 51 by the hydraulic cylinder 73, which squeezes the fertilizer production raw materials that have fallen into the positioning tube 51 downward. After being squeezed, the fertilizer raw materials will be squeezed out along the multiple shaping holes 54 drilled inside the extrusion plate 74. The squeezed fertilizer raw materials will form long strips of uniform thickness.

[0037] The scraping and shaping granulation structure of granulation equipment used in fertilizer production and processing:

[0038] The scraper rod 65 is a rectangular horizontal long rod made of aluminum alloy. The top of the scraper rod 65 is close to the lower end face of the shaping hole 54. The receiving hopper 62 is made of stainless steel mesh frame and welded to the outside of the output shaft of the motor 61. When the power is connected and the motor 61 is started, the output shaft of the motor 61 can drive the scraper rod 65 and the receiving hopper 62 to rotate at the same time. The scraper rod 65 periodically scrapes off the fertilizer strips extruded from below the forming plate 53. The scraped fertilizer segments will fall into the inside of the receiving hopper 62 for storage. As the receiving hopper 62 also rotates continuously, the bucket-shaped receiving hopper 62 can shake the fertilizer granules into uniformly sized granules. Finally, the motor 61 is stopped, and the operator manually unscrews the screw 64 through the slotted holes 81 on both sides. The material receiving plate 63 flips down and opens, discharging the fertilizer production granules formed inside the receiving hopper 62.

[0039] The structure of a wind-powered rapid drying and shaping device for fertilizer production and processing:

[0040] The slotted hole 81 facilitates manual material handling. The blower 82 uses a motor to drive a fan to generate airflow. After the blower 82 is connected to the power supply and started, the airflow drawn in by the air inlet pipe 83 is blown vertically upward along the blower head 84. The airflow can then pass through the holes below the receiving hopper 62 to quickly shape the granulated fertilizer. In this way, the final shaped fertilizer does not need to wait for the cooling and drying process and can be quickly handled, which facilitates subsequent fertilizer production and improves the working efficiency of the granulation device used for fertilizer production and processing.
