Description

Technical Field

[0001] This utility model relates to the technical field of compound fertilizer production equipment, and in particular to an integrated device for crushing and homogenizing compound fertilizer biomass raw materials. Background Technology

[0002] In the field of compound fertilizer production, the crushing and homogenization of biomass raw materials are key steps to ensure the quality and efficacy of compound fertilizers. In the traditional process of processing biomass raw materials for compound fertilizers, crushing and homogenization operations are often carried out in separate steps using independent equipment. First, the biomass raw materials are crushed by a crusher, and then the crushed materials are transferred to a mixer for mixing and homogenization.

[0003] This step-by-step processing method has many drawbacks: First, it requires a large area, necessitating multiple machines to complete the crushing and homogenizing operations, increasing the company's factory construction and equipment purchase costs; second, it has low production efficiency, as transferring materials between different machines is time-consuming and labor-intensive, and multiple transfers can easily lead to material loss and waste; third, it has poor homogenization effect, as the low parameter matching between different machines makes it difficult to achieve precise material processing, resulting in inconsistent quality of the mixed compound fertilizer and affecting its effectiveness; fourth, it has high maintenance costs, as the operation and maintenance of multiple machines require a significant investment of manpower, material resources, and financial resources, increasing the company's operational burden.

[0004] With the increasing demands for production efficiency, product quality, and cost control in the compound fertilizer industry, traditional step-by-step processing equipment can no longer meet market demands.

[0029] Reference Figure 1-6 An integrated crushing and homogenizing device for compound fertilizer biomass raw materials includes a lower mixing tank 1, two upper mixing tanks 2, a second rotating shaft 31, two first rotating shafts 3, a feeding cylinder 12, a first feeding hopper 121, two second feeding hoppers 21, and multiple discharge pipes 11. The feeding cylinder 12 and the two upper mixing tanks 2 are fixedly installed on the top of the lower mixing tank 1 and are respectively connected to the lower mixing tank 1. The first feeding hopper 121 and the second feeding hopper 21 are respectively fixedly installed on the feeding cylinder 12 and the upper mixing tank 2. The two first rotating shafts 3 are respectively rotatably installed in the corresponding upper mixing tank 2. The two first rotating shafts 3 extend to the bottom of the lower mixing tank 1, and each of the two first rotating shafts 3 is fixedly installed with a spiral blade 303. The two spiral blades 303 are respectively located at the connection between the corresponding upper mixing tank 2 and the lower mixing tank 1. The second rotating shaft 31 is rotatably installed in the lower mixing tank 1.

[0030] Multiple stirring rods 301 are radially fixedly installed on both rotating shafts 3. The multiple stirring rods 301 are located in the corresponding upper mixing tank 2, and can stir the material in the upper mixing tank 2 when the rotating shaft 3 rotates.

[0031] Multiple stirring paddles 302 are radially fixedly installed on the second rotating shaft 31 and the two first rotating shafts 3. The multiple stirring paddles 302 are all located inside the lower mixing tank 1. The stirring paddles 302 on the first rotating shaft 3 and the stirring paddles 302 on the second rotating shaft 31 are staggered. When the first rotating shaft 3 and the second rotating shaft 31 rotate, the material in the lower mixing tank 1 can be stirred, so that it can be quickly and evenly mixed.

[0032] Both shaft 1 3 are fixedly fitted with driven gears 34 at their bottom ends. The bottom end of shaft 2 31 is fixedly installed with drive gears 33 that mesh with the two driven gears 34. A motor 32 is fixedly installed below the lower mixing tank 1. The output shaft of motor 32 is axially fixedly connected to the bottom end of shaft 2 31, which can provide driving force for shaft 1 3 and shaft 2 31, and at the same time can make shaft 1 3 and shaft 2 31 rotate in opposite directions.

[0033] An upper cutter 22 is fixedly installed on the lower part of the inner wall of the second feed hopper 21. A rotating ring 23 is rotatably installed on the bottom of the outer side of the second feed hopper 21. A lower cutter 24 that is in movable contact with the upper cutter 22 is fixedly installed on the inner wall of the rotating ring 23. When the rotating ring 23 rotates, the lower cutter 24 and the upper cutter 22 cooperate to cut and crush the material entering through the right feed hopper 21.

[0034] A transmission gear 4 is fixedly sleeved on the rotating shaft 3, and a toothed disc 41 is fixedly sleeved on the outer side of the rotating ring 23. The transmission gear 4 and the toothed disc 41, which are located in the same upper mixing tank 2, mesh with each other and can provide driving force to the rotating ring 23 when the rotating shaft 3 rotates.

[0035] Multiple discharge pipes 11 are equipped with valves and are radially fixedly installed on the outer bottom of the lower mixing tank 1.

[0036] In this embodiment, in order to scrape the material at the bottom inner wall of the lower mixing tank 1 when the rotating shaft 3 rotates, not only can the material be turned over, but the material can also be pushed towards the discharge pipe 11 when unloading is required. The multiple stirring paddles 302 located at the bottom of the rotating shaft 3 are in contact with the bottom inner wall of the lower mixing tank 1.

[0037] In this embodiment, in order to provide shielding protection for the transmission gear 4 and the gear disc 41, a partition 201 is fixedly installed on the upper part of the inner wall of the upper mixing tank 2. The rotating ring 23 passes through the partition 201 and maintains a sealed rotating connection with the partition 201. The rotating shaft 3 is rotatably connected to the partition 201.

[0038] In this embodiment, in order to provide stable support for the motor 32, multiple support legs are fixedly installed at the bottom of the lower mixing tank 1, and the same tray 321 is fixedly installed on the multiple support legs. The motor 32 is fixedly installed on the tray 321.

[0039] In this embodiment, in order to control whether the material in the upper mixing tank 2 is transported to the lower mixing tank 1 by controlling the rotation direction of the rotating shaft 3, the two spiral blades 303 have the same spiral direction.

[0040] The circuits, electronic components, and modules involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve improvements to the software, cables, or methods.

[0041] Working principle: When in use, first connect the power supply and start the motor 32. Pour the biomass raw materials to be mixed from the feed hopper 21 into the upper mixing tank 2. Materials that do not need to be crushed are poured directly into the lower mixing tank 1 from the feed hopper 121 through the feed cylinder 12. The output shaft of the motor 32 drives the rotating shaft 31 to rotate. At the same time, under the cooperation of the drive gear 33 and the two driven gears 34, the two rotating shafts 31 and the rotating shaft 31 rotate in opposite directions.

[0042] Inside the upper mixing tank 2, the stirring rod 301 on the rotating shaft 3 performs preliminary stirring of the material to ensure that the material is evenly distributed in the upper mixing tank 2. At the same time, when the rotating shaft 3 rotates, the rotating ring 23 is driven to rotate through the meshing action of the transmission gear 4 and the gear plate 41. The lower cutter 24 on the inner wall of the rotating ring 23 cooperates with the upper cutter 22 on the inner wall of the feed hopper 21 to cut and crush the material entering the upper mixing tank 2, making its particle size more uniform.

[0043] After the material is crushed and mixed evenly, by controlling the rotation direction of the rotating shaft 3, the spiral blades 303 can transport the material in the upper mixing tank 2 to the lower mixing tank 1. In the lower mixing tank 1, the rotating shaft 31 and the stirring paddles 302 on the two rotating shafts 3 are arranged in an alternating manner, which can perform a tumbling operation on the material to further ensure that the material is mixed evenly. The stirring paddle 302 located at the bottom of the rotating shaft 3 is in contact with the bottom inner wall of the lower mixing tank 1, which can scrape the material at the bottom inner wall when rotating, preventing the material from accumulating at the bottom. At the same time, it can push the material towards the discharge pipe 11 when it is necessary to discharge, which is convenient for unloading.

[0044] Once the mixture is thoroughly mixed, open the valve on the discharge pipe 11, and the material can be discharged from the discharge pipe 11.

[0045] The above provides a detailed description of the integrated crushing and homogenizing device for compound fertilizer biomass raw materials provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
