Description

Technical Field

[0001] This utility model relates to the field of fertilizer mixing technology, specifically to an integrated device for mixing and sorting carbon-based compound fertilizers. Background Technology

[0002] In the continuous development of agricultural production, fertilizers, as a key element in ensuring the healthy growth of crops and improving yield and quality, are undeniably important. With the continuous advancement of agricultural technology, the requirements for fertilizer types and performance are becoming increasingly diversified and refined. Biochar-based compound fertilizers, as a new type of fertilizer, have gradually emerged in the agricultural field in recent years. Biochar-based compound fertilizers are made by scientifically blending nitrogen, phosphorus, potassium, and various micronutrients in a specific ratio using biochar as the main carrier. Biochar has a rich porous structure, which gives it a strong adsorption capacity, effectively adsorbing and fixing nutrients in fertilizers, reducing nutrient loss and volatilization, and improving fertilizer utilization. At the same time, biochar can also improve the physical and chemical properties of soil, increase soil permeability and water retention, create a favorable soil environment for crop root growth, and promote the absorption and utilization of nutrients by crops.

[0003] However, existing production equipment presents numerous problems in the actual production of carbon-based compound fertilizers. Traditional production methods typically separate mixing, screening, granulation, and drying processes. This not only requires significant production space but also involves cumbersome material transfer between processes, increasing production costs and time. Furthermore, the lack of effective integration and collaborative mechanisms between different pieces of equipment results in low automation, numerous manual operations, and a high risk of human error, affecting the consistency and stability of product quality. Moreover, in the drying stage, most existing drying equipment employs a single drying layer design. When drying different batches or types of compound fertilizer granules, the current drying layer must complete its drying process before the next batch can begin, hindering continuous production and reducing efficiency.

[0004] To address the aforementioned issues, improve the production efficiency and product quality of carbon-based compound fertilizers, and reduce production costs, we propose an integrated mixing and sorting device for carbon-based compound fertilizers. Utility Model Content

[0021] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: an integrated device for mixing and sorting carbon-based compound fertilizer, including an integrated frame 1, a screening mixer 2, a moving clamping device 3, a clamping and pushing device 4, a granulator 5, and a dryer 6.

[0022] The integrated frame 1 has a top layer, a middle layer, and a bottom layer, providing a stable support structure for the entire device. The top layer of the integrated frame 1 is connected to the screening and mixing machine 2, which is used for screening and mixing raw materials.

[0023] The integrated frame 1 is slidably connected to the movable clamping device 3 in the middle layer. The clamping and pushing device 4 is connected to the side wall of the middle layer of the integrated frame 1.

The bottom of the movable clamping device 3 clamps the dryer 6, which can dry the granulated fertilizer.

[0024] The clamping and pushing device 4 can be a cylinder with a diameter of 100mm. In this embodiment, two clamping and pushing devices 4 are used, which can push the moving clamping device 3 more evenly.

[0025] The bottom layer of the integrated frame 1 is connected to the granulator 5, which is used to make granular fertilizer from the mixed and stirred materials.

[0026] The discharge port of the screening and mixing machine 2 is connected to the feed port of the granulator 5, ensuring that the screened and mixed material can smoothly enter the granulator 5 for granulation. It should be noted that the discharge port of the screening and mixing machine 2 is connected to the feed port of the granulator 5 via a corrugated pipe or an adjustable-length flexible hose, allowing for adaptive adjustment of the pipeline when the granulator 5 is raised or lowered.

[0027] Furthermore, the integrated frame 1 includes a main support frame 11, an auxiliary platform 12, and a lifting platform integrated device 13. The auxiliary platform 12 and the lifting platform integrated device 13 are provided on the inner bottom of the main support frame 11. The auxiliary platform 12 is used to place the dryer 6. When the dryer 6 is working normally, the moving clamping device 3 does not need to hold the dryer 6 at all times. The moving clamping device 3 places the dryer 6 on the auxiliary platform 12 for stable operation.

[0028] The top surface of the lifting platform integrated device 13 is connected to the granulator 5. The height of the granulator 5 can be adjusted by the lifting platform integrated device 13. Combined with the moving clamping device 3, it can more accurately adapt to different production needs.

The lifting platform drive device 132 is connected within the lifting platform frame 133. In this embodiment, a DTZ-500 electric push rod is selected as the lifting platform drive device 132, which has advantages such as large thrust, stable operation, and high control precision, and can meet the requirements for stable lifting of the lifting platform.

[0030] The lifting platform drive device 132 is connected to the lifting platform 131. The lifting platform 131 moves up and down through the drive of the lifting platform drive device 132. The top surface of the lifting platform 131 is connected to the granulator 5, thereby driving the granulator 5 to adjust its height.

[0031] Furthermore, the screening and mixing machine 2 includes a drive motor 21, a transmission box 22, a mixing chamber 23, a first mixing roller 24, a second mixing roller 25, and a screening screen 26. The transmission box 22 includes an input end, a first output end, and a second output end.

The first output end of the transmission box 22 is connected to one end of the first stirring roller 24, and the second output end of the transmission box 22 is connected to one end of the second stirring roller 25. The other ends of the first stirring roller 24 and the other ends of the second stirring roller 25 are rotatably connected to the inner sidewall of the mixing tank 23.

[0033] The drive motor 21 drives the first stirring roller 24 and the second stirring roller 25 to rotate simultaneously through the transmission box 22, so as to fully mix the material. The screen 26 is provided at the feed inlet of the mixing box 23, so as to screen the material as it enters the mixing box and remove impurities or large particles that do not meet the requirements.

[0034] Furthermore, the mobile clamping device 3 includes a clamping lifting cylinder 31, a slide table 32, a clamping control cylinder 33, a connecting plate 34, a gripper integration device 35, and a base plate 36.

[0035] The slide table 32 is slidably connected to the middle layer of the integrated frame 1 and can slide horizontally on the middle layer of the integrated frame; the top surface of the slide table 32 is connected to the clamping lifting cylinder 31; the driving end of the clamping lifting cylinder 31 passes through the slide table 32 and is connected to the substrate 36, and the substrate can move up and down by driving the clamping lifting cylinder; the side wall of the substrate 36 is connected to the clamping control cylinder 33; the driving end of the clamping control cylinder 33 is connected to the side wall of the connecting plate 34; the side wall of the connecting plate 34 is fixedly connected to the clamping claw integrated device 35 for clamping the dryer 6, and the clamping claw integrated device can be controlled to clamp or release the dryer by driving the clamping control cylinder.

[0036] The clamping and lifting cylinder 31 can be a 160mm diameter cylinder, and the clamping control cylinder 33 can be a 120mm diameter cylinder.

[0037] Furthermore, the integrated gripper device 35 includes a mounting plate 351, a gripping cylinder 352, a clamping plate 353, and a gripping guide post 354. The side wall of the mounting plate 351 is connected to the connecting plate 34 near the top; the gripping cylinder 352 is mounted on the side wall of the mounting plate 351, and the driving end of the gripping cylinder 352 passes through the mounting plate 351 and connects to the side wall of the clamping plate 353; one end of the gripping guide post 354 is connected to the side wall of the clamping plate 353; the other end of the gripping guide post 354 is slidably connected to the mounting plate 351. When the gripping cylinder 352 drives the clamping plate 353 to move, the gripping guide post 354 provides guidance, ensuring the stability of the movement of the clamping plate 353 and also providing a certain amount of support.

[0038] In this embodiment, four clamping cylinders 352 are provided. The clamping cylinders 352 are standard cylinders of model ISO15552. This invention selects ISO15552 standard cylinders with a cylinder diameter of 100mm. Under a working pressure of 0.6MPa, the total output force of the four cylinders can reach 4×4712N=18848N, and the total return force can reach 4×4418N=17672N. Considering the static clamping force, the total clamping force of the four cylinders can reach 4×8000N=32000N. It has advantages such as simple structure, reliable operation, and convenient maintenance, and can meet the requirements for clamping and lifting.

[0039] Furthermore, the contact surface between the clamping plate 353 and the dryer 6 is provided with an anti-slip layer, which can be made of rubber, to increase the friction between the clamping plate 353 and the dryer 6, prevent the dryer 6 from slipping during clamping, and improve the stability of clamping.

[0040] Furthermore, the dryer 6 is equipped with multiple drying layers, which can simultaneously dry fertilizers of different batches or in different states, thereby improving drying efficiency and meeting the needs of large-scale production.

[0041] Working principle: In the mixing and screening stage, the raw materials for the carbon-based compound fertilizer are fed into the inlet of the screening mixer 2. The raw materials are first screened through the screening screen 26 to remove impurities and large particles. At the same time, the drive motor 21 starts, driving the first stirring roller 24 and the second stirring roller 25 to rotate through the transmission box 22, thoroughly mixing the raw materials to ensure uniform distribution of various nutrients. The uniformly mixed raw materials enter the granulator 5 from the outlet of the screening mixer 2.

[0042] The granulator 5 is mounted on the lifting platform 131. The lifting platform drive device 132 can move the position of the dryer 6 according to the moving clamping device 3, thereby assisting in adjusting the height of the granulator 5. After the raw material enters the granulator 5, it is formed into granular carbon-based compound fertilizer under the action of the granulator 5.

[0043] The granulated carbon-based compound fertilizer granules enter the dryer 6 for drying. The dryer 6 has multiple drying layers. When a drying layer is in operation, the clamping and pushing device 4 is activated, pushing the moving clamping device 3 to slide in the middle layer of the integrated frame 1. At the same time, the clamping lifting cylinder 31 is activated to adjust the height of the dryer 6, and new compound fertilizer granules are sent to other idle drying layers for drying, so as to achieve continuous production.

[0044] The working process of the mobile clamping device 3 is as follows: First, the entire mobile clamping device 3 is pushed above the dryer 6 by the clamping pushing device (4). Then, the clamping control cylinder 33 is activated, pushing the connecting plate 34 and the clamping claw integrated device 35 closer to the dryer 6. The clamping cylinder 352 is activated, driving the clamping plate 353 to clamp the dryer 6. The clamping guide column 354 plays a guiding and stabilizing role, preventing the clamping plate 353 from shifting during the clamping process. The clamping lifting cylinder 31 can adjust the height of the dryer 6. The slide table 32 slides in the middle layer of the integrated frame 1 to realize the horizontal movement of the dryer 6.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
