Description

Technical Field

[0001] This utility model relates to the technical field of compound fertilizer production equipment, specifically a three-dimensional device for producing amino acid compound fertilizer. Background Technology

[0002] Compound fertilizer production equipment typically includes a granulator, dryer, cooler, screening machine, and coating machine. During use, the material is first metered by the batching equipment and then enters the granulator for granulation. After granulation, it is dried by the dryer and cooled by the cooler, and then screened by coarse and fine sieves. The large particles after coarse sieve and the powdery material after fine sieve are returned to the granulator for granulation again. The qualified products are then coated by the coating machine and finally packaged in the finished product warehouse.

[0003] Currently, material transport between the aforementioned devices is achieved via elevators or belt conveyors, and each device typically has only two floors of installation space. For example, before the improvement, our screening machine was installed on the second floor. After the material came out of the cooler, it was first lifted by an elevator to the screening machine for screening. The screened material needed to be lifted again by another elevator to the intermediate loading station. After cooling at the intermediate loading station, it was sent to the belt conveyor at the bottom, and finally lifted again by an elevator to the coating machine for coating treatment. The cooling treatment at the intermediate loading station ensured that the temperature of the material entering the coating machine met the standards. However, due to the limitation of installation space, the current location of the intermediate loading station is higher than the screening machine. Therefore, the material coming out of the screening machine needs to be lifted by an elevator to the transfer station.

[0004] However, the above process alone requires three lifts, resulting in high energy consumption and operating costs for the elevators during actual use. Furthermore, the large number of elevators increases the complexity of coordinated operations and the required floor space. Therefore, our company has improved the equipment layout by designing a three-dimensional compound fertilizer system. This system fully utilizes vertical space, reduces the number of elevators, saves on equipment purchase and maintenance costs, simplifies the conveying process, and improves production efficiency. Utility Model Content

[0005] This invention provides a three-dimensional device for amino acid compound fertilizer production, which can solve the technical problems of high energy consumption, high maintenance costs, and increased complexity of collaborative operation caused by the large number of elevators used in the screening stage of existing compound fertilizer production equipment.

[0006] This application provides the following technical solution:

[0007] A three-dimensional device for producing amino acid compound fertilizer includes a grading screen located above the second floor and a first cooler located below the second floor. The first cooler and the grading screen are connected by a first elevator. A second cooler, a second elevator, and a coating machine are also provided at the rear end of the grading screen. The second cooler is vertically installed on the second floor slab. The upper end of the second cooler is connected to the discharge port of the grading screen, and the lower end of the second cooler extends to the first floor and is connected to a belt conveyor. The inlet of the second elevator is connected to the belt conveyor, and the outlet is connected to the coating machine, which is located above the second floor.

[0008] Beneficial effects:

[0009] 1. High space utilization: The coating machine and grading screen are located on the upper part of the second floor, while the first cooler and belt conveyor are located on the lower part of the second floor. The first and second elevators are vertically arranged for conveying materials, and the second cooler is vertically arranged for cooling materials. The various equipment forms a three-dimensional layout in the vertical direction, making full use of vertical space. In particular, the vertical arrangement of the second cooler reduces the horizontal footprint of the equipment and also serves as a material unloading channel. This makes the overall layout of the workshop more compact and reasonable, with good space utilization, saving valuable production space for the company and facilitating future expansion of production scale.

[0010] 2. Reduce the number of elevators and simplify the operation process: By setting the grading screen on the second floor, its position is raised compared to the original design. Furthermore, the upper end of the second cooler is connected to the discharge port of the grading screen. The screened material can directly enter the second cooler, achieving effective connection. There is no need to install an elevator between the screening machine and the second cooler, reducing the number of elevators. This reduces energy consumption and lowers equipment purchase and maintenance costs for the company. Additionally, reducing one elevator also reduces the space required for installation, simplifies the conveying process, and reduces the complexity of collaborative operations, thus improving conveying and production efficiency.

[0011] 3. Improved Product Quality and Reduced Adhesion: By setting a first cooler at the front end of the grading screen and a second cooler at the rear end, the temperature of the material entering the coating machine can be ensured to be below 40℃. This reduces the problem of material adhesion and caking caused by high temperatures during the coating stage, thus improving product quality. Compared to setting only one cooler at the front end of the grading screen and rapidly reducing the temperature of the dried material to below 40℃ in one go, the large differences in particle diameter and the large quantity of material before screening necessitate increased energy consumption from the first cooler and reduced conveying speed for rapid cooling. The two-stage cooling method in this application saves energy and ensures more uniform material cooling. Furthermore, the material has sufficient time to cool naturally at the transition point between the first and second coolers, further reducing the energy consumption required by the second cooler.

[0012] Furthermore, the bottom of the grading screen is equipped with a powder discharge pipe, a coarse material discharge pipe, and a dust collection hood. The dust collection hood is connected to the air inlet pipe of the first cooler through a dust removal pipe.

[0013] Beneficial effects: The grading screen is used to separate powder and large coarse particles from the material, thereby obtaining granular material of the required particle size; by connecting the dust collection hood set on the grading screen to the air inlet pipe of the first cooler, it can be used as the natural air of the first cooler to cool the material, which helps to simplify the number of pipes, reduce the number of induced draft fans, and reduce energy consumption.

[0014] Furthermore, a raw material scraper is installed on the ground floor. The powder discharge pipe and the coarse material discharge pipe are connected to the raw material scraper, which is used to send the powder and coarse material to the granulator.

[0015] Beneficial effects: The raw material scraper conveyor is located below the first floor, which can make full use of vertical space and reduce the floor area occupied by the material on the upper floors.

[0016] Furthermore, a dust removal main pipe is installed on the second floor, and an air outlet is installed at the front end of the first cooling machine. The air outlet is connected to the dust removal main pipe on the second floor through an air suction pipe, and a dust collector is installed at one end of the dust removal main pipe.

[0017] Beneficial effects: Setting the main dust collection pipe on the second floor facilitates connection with the dust collection pipes of the equipment located on the first and third floors, optimizes the pipeline layout, and also facilitates centralized maintenance.

[0018] Furthermore, the grading sieve and coating machine are located on the third floor.

[0019] Beneficial effects: It makes full use of vertical space, and the space left on the second floor also makes it easier to observe and maintain equipment located at the top and bottom of the second floor.

[0020] Furthermore, the packaging machine has a main discharge pipe at its outlet, and several branch discharge pipes at the bottom of the main discharge pipe; several packaging lines are set on the first floor, and each branch discharge pipe is connected to a packaging line.

[0021] Beneficial effects: Because the wrapping machine is set up at a high position, it is beneficial for the material to fall naturally from the discharge main pipe to the packaging bin at the bottom; the high position of the wrapping machine also makes it easier to arrange the feed branch pipes according to the packaging line below, improving space utilization; setting up multiple packaging lines and feed branch pipes helps to improve production efficiency.

[0022] Furthermore, the wrapping machine is equipped with a dust removal pipe, which is connected to the main dust removal pipe on the second floor.

[0023] Beneficial effect: It allows the dust generated during the coating stage of the coating machine to enter the dust collection main pipe, which helps maintain the environment of the entire production workshop.

[0024] Furthermore, a first screening machine is installed at the front end of the cooler. The first screening machine is located on the second floor. The feed inlet of the first screening machine is connected to the dryer through an elevator, and the discharge outlet of the first screening machine is connected to the feed inlet of the first cooler through a discharge chute.

[0025] Beneficial effects: The first screening machine is mainly used to remove fine powder materials produced by high-temperature drying, thus achieving the initial screening of materials.

[0026] Furthermore, the first cooler is a drum-type cooler, and the second cooler is a plate cooler.

[0027] Beneficial effects: The drum cooler mainly uses natural wind to initially cool the material, while the plate cooler uses cooling water to deeply cool the material, thereby ensuring the internal cooling effect of the granular material and further improving the product quality in the coating stage.

[0028] Furthermore, a discharge hopper is installed below the plate cooler, and the discharge hopper is connected to the belt conveyor.

[0029] Beneficial effect: Setting up a discharge hopper facilitates the feeding of materials onto the belt conveyor. Attached Figure Description

[0030] Figure 1 This is a schematic diagram of the structure of a three-dimensional device for amino acid compound fertilizer according to embodiment one of the present invention. Detailed Implementation

[0031] The following detailed description illustrates the specific implementation method:

[0032] The markings in the attached drawings of the instruction manual include: First cooler 1, air inlet pipe 11, suction pipe 12, first elevator 2, grading screen 3, powder discharge pipe 31, coarse material discharge pipe 32, dust suction hood 33, second cooler 4, discharge funnel 41, belt conveyor 5, second elevator 6, coating machine 7, main discharge pipe 71, raw material scraper conveyor 8, first screening machine 9, discharge chute 91, dust removal main pipe 100, dust removal pipe 1001, first floor 101, second floor 102, third floor 103.

[0033] Example 1

[0034] like Figure 1As shown, a three-dimensional device for amino acid compound fertilizer includes a grading screen 3 located above the second floor 102 and a first cooler 1 located below the second floor 102. The first cooler 1 and the grading screen 3 are connected by a first elevator 2, and the discharge port of the first elevator 2 is provided with a chute. A second cooler 4, a second elevator 6, and a coating machine 7 are also provided at the rear end of the grading screen 3. The second cooler 4 is vertically installed on the floor slab of the second floor 102. The upper end of the second cooler 4 is connected to the discharge port of the grading screen 3, and the lower end of the second cooler 4 extends to the first floor 101 and is connected to a belt conveyor 5. The inlet of the second elevator 6 is connected to the belt conveyor 5, and the outlet is connected to the coating machine 7, which is located above the second floor 102.

[0035] Specifically, in this embodiment, the grading screen 3 and the coating machine 7 are located on the third floor 103. In other embodiments, the grading screen 3 and the coating machine 7 can also be located on the fourth floor or above, or an installation platform can be built directly on the second floor 102, and the grading screen 3 can be placed on the installation platform. The space left on the second floor 102 can also facilitate the observation and maintenance of the equipment at the top and bottom of the second floor 102. In this embodiment, by placing the grading screen 3 on the third floor 103, the position of the grading screen 3 is raised compared to the previous method, so that the upper end of the second cooler 4 can be directly connected to the discharge port of the grading screen 3. The screened material can directly enter the second cooler 4, thereby achieving effective connection. There is no need to set up an elevator between the grading screen 3 and the second cooler 4, reducing the number of elevators. In addition, reducing one elevator can also reduce the occupation of installation space, simplify the conveying process, reduce the complexity of collaborative operation, and help improve conveying efficiency and production efficiency.

[0036] Specifically, the first cooler 1 is a drum-type cooler, and the second cooler 4 is a plate cooler. The first cooler 1 is arranged horizontally on the first floor 101, and the second cooler 4 is vertically installed on the second floor 102. A discharge hopper 41 is also installed below the second cooler 4, and the discharge hopper 41 is connected to the belt conveyor 5. The first cooler 1 mainly uses natural wind to initially cool the material, while the second cooler 4 uses cooling water to deeply cool the material, thereby ensuring the cooling effect inside the granular material, further improving the product quality in the subsequent coating stage, and reducing the problems of material adhesion and caking.

[0037] Compared to simply setting up a cooler at the front end of the grading screen 3 and rapidly cooling the dried material at once, which requires increasing the cooling energy consumption of the first cooler 1 and reducing the conveying speed due to the large difference in particle diameter and large quantity of material before screening, this application's two-stage cooling method saves energy and ensures more uniform material cooling. Furthermore, the material has sufficient time to cool naturally at the transition point between the first cooler 1 and the second cooler 4, which further reduces the energy consumption required by the second cooler 4.

[0038] The bottom of the grading screen 3 is equipped with a powder discharge pipe 31, a coarse material discharge pipe 32 and a dust suction hood 33. The dust suction hood 33 is connected to the air inlet pipe 11 of the first cooler 1 through a dust removal pipe 1001. A raw material scraper 8 is installed below the first floor 101. The powder discharge pipe 31 and the coarse material discharge pipe 32 are connected to the raw material scraper 8. The raw material scraper 8 is used to send the powder and coarse material to the granulator.

[0039] In operation, the material enters the grading screen 3 after passing through the first elevator 2. The grading screen 3 separates the powder and large coarse particles to obtain granular material of the required particle size. This material enters the second cooler 4 through the product outlet of the grading screen 3, while the screened material enters the raw material scraper 8 below along the discharge pipe and is then conveyed to the granulator for further granulation. In this embodiment, the dust generated during the screening stage is sucked away by the dust suction hood 33 of the grading screen 3 and enters the first cooler 1 along the dust removal pipe 1001, serving as natural airflow in the first cooler 1 to cool the material.

[0040] A dust collection main pipe 100 is installed on the second floor 102. An air outlet is provided at the front end of the first cooler 1. The air outlet is connected to the dust collection main pipe 100 on the second floor 102 through an air suction pipe 12. One end of the dust collection main pipe 100 is connected to a dust collector (not shown in the figure). A dust collection pipe 1001 is also provided on the coating machine 7, and the dust collection pipe 1001 is connected to the dust collection main pipe 100 on the second floor 102. In this embodiment, the dust collection main pipe 100 is set on the second floor 102, which is conducive to connecting with the dust collection pipes 1001 of the equipment set on the first floor 101 and the third floor 103, which is conducive to optimizing the pipeline layout and also facilitates centralized maintenance. The dust-laden gas entering the dust collection main pipe 100 enters the dust collector at the rear end. Specifically, the dust collector can be a cyclone dust collector or a bag dust collector, or both. The gas after dust removal by the dust collector is discharged through the chimney of the factory area.

[0041] In this embodiment, the discharge port of the wrapping machine 7 is provided with a discharge main pipe 71, and the bottom of the discharge main pipe 71 is connected to several feed branch pipes (not shown in the figure); the first floor 101 is provided with several packaging lines, and each feed branch pipe is connected to a packaging line; since the wrapping machine 7 is set at a high position, it is beneficial for the material to fall naturally from the discharge main pipe 71 to the packaging bin at the bottom; and the high position of the wrapping machine 7 is also beneficial for arranging the feed branch pipes according to the packaging lines below, thereby improving space utilization; the provision of multiple packaging lines and feed branch pipes in this embodiment is beneficial for improving production efficiency.

[0042] The first cooling machine 1 is also equipped with a first screening machine 9 at its front end. The first screening machine 9 is located on the second floor 102. The feed inlet of the first screening machine 9 is connected to the dryer through an elevator, and the discharge outlet of the first screening machine 9 is connected to the feed inlet of the first cooling machine 1 through a discharge chute 91. The first screening machine 9 is mainly used to screen out fine powder materials generated during the high-temperature drying stage, thereby achieving the initial screening of the materials.

[0043] In use, the material granulated by the granulator is dried in the dryer. The dried material enters the first screening machine 9 for initial screening. The screened material falls naturally into the first cooler 1 through the discharge chute 91 for initial cooling. The material is discharged from the discharge port of the first cooler 1 into the hopper of the first elevator 2. The first elevator 2 lifts the material to the grading screen 3 for fine screening. The resulting granular material enters the second cooler 4 through the discharge port of the grading screen 3 for further cooling, and is discharged along the second cooler 4 onto the belt conveyor 5. The belt conveyor 5 transports the material to the second elevator 6. The second elevator 6 lifts the material to the high-level wrapping machine 7. The material processed by the wrapping machine 7 is discharged from the discharge main pipe 71 and sequentially enters the bottom packaging line through different discharge branch pipes for packaging.

[0044] The compound fertilizer three-dimensional device provided in this application makes full use of vertical space, making the overall layout of the workshop more compact and reasonable, with good space utilization, saving valuable production space for enterprises and facilitating subsequent expansion of production scale; and by optimizing the layout of the device, the number of elevators is reduced, saving enterprises equipment purchase and maintenance costs, while also simplifying the conveying process and effectively improving the conveying efficiency and production efficiency of compound fertilizer.
