Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer production, and in particular to a powder water-soluble fertilizer production system. Background Technology

[0002] Water-soluble powder fertilizer is a new type of fertilizer product. Its main characteristic is its rapid dissolution in water, facilitating direct absorption and utilization by crop roots. It typically contains macro-, meso-, and micro-elements essential for crop growth. Present in powder form, it dissolves completely in water to form a homogeneous solution without residue. Its high solubility allows for rapid absorption by plants, resulting in high fertilizer utilization. Furthermore, the formula and dosage can be adjusted according to different growth stages and needs of the crop, and it can be applied directly to the roots through the irrigation system, saving labor. However, due to its powdered form, water-soluble powder fertilizer requires self-dilution before use. Therefore, it is crucial to strictly follow the product instructions for dilution and application to avoid excessive concentrations that could burn roots. The appropriate fertilizer type and dosage should be selected based on the soil and crop conditions, and attention should be paid to the timing and method of application to maximize its effectiveness.

[0024] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0025] In the following description, specific examples of general selection are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0026] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of a feature, whole, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, or combinations thereof.

[0027] Please see Figure 1 and Figure 2This utility model discloses a powder water-soluble fertilizer production system, comprising a steel frame 1, with several feeding ports 2 installed on the top layer of the steel frame 1. The lower outlets of the feeding ports 2 are all connected to a first crusher 3. The lower part of the first crusher 3 is connected to a first weight reduction bin 4. A weighing system is installed in the first weight reduction bin 4, and the weighing system controls a screw feeder 5. The screw feeder 5 distributes the powder to a conveyor 6 located at the bottom layer of the steel frame 1. The system also includes a bucket elevator 7. The conveyor 6 is connected to the bottom inlet of the bucket elevator 7. The bucket elevator 7 lifts the powder from the inlet to its top outlet. The outlet is connected to a second weight reduction bin 8 installed on the top layer of the steel frame 1. The bottom outlet of the second weight reduction bin 8 is connected to a mixer 9. The mixer 9 transfers the mixed powder from its bottom outlet to a powder packaging scale 10, and then packages it to complete the production.More specifically, in this embodiment, four feeding ports 2 are designed at the top of the steel frame 1. A transition chamber 12 is designed between the feeding ports 2 and the first crusher 3 for connection. The transition chamber 12 is located below the feeding ports 2 and connected to the outlet of the feeding ports 2. The transition chamber 12 can regulate the material flow rate to ensure that the material enters the crusher at a uniform and controllable speed, avoiding overload or idling of the crusher due to fluctuations in material flow rate. Moreover, when the upstream material supply is unstable or needs to be temporarily stopped, the transition chamber 12 can act as a buffer to ensure the continuous operation of the crusher, reduce production interruptions, and then transition... The discharge port at the bottom of bin 12 is connected to the first crusher 3. In this embodiment, the first crusher 3 is designed as a rod crusher. Rod crushers are typically used for coarse and medium crushing. They can handle larger pieces of material, and because their long steel rods serve as the crushing medium, they can grind the powder while crushing. The powder crushed by the rod crusher enters the first weight reduction bin 4. The first weight reduction bin 4 monitors the weight change of the powder in the bin in real time through a weighing system, thereby controlling the screw feeder 5 to achieve precise feeding. The first weight reduction bin 4 can continuously feed materials according to the needs of the production line, ensuring material flow. To ensure stability, the screw feeder 5 distributes the powder to the conveyor 6. In this embodiment, the conveyor 6 is a self-cleaning scraper conveyor. The self-cleaning scraper conveyor can clean the conveying trough walls while conveying materials, and it has a discharge port at the bottom of the conveying trough for easy cleaning and removal of powder. Therefore, the self-cleaning scraper conveyor can prevent powder adhesion and accumulation when conveying powder. Then, the self-cleaning scraper conveyor transports the powder to the bucket elevator 7. The bucket elevator 7 lifts the powder from the bottom of the steel frame 1 to the top of the steel frame 1 and transfers the powder to the second weight-reducing bin 8. The second weight-reducing bin 8 is also equipped with... A mixer 9 is connected to the discharge port at the bottom of the second weight-reducing chamber 8, which is mounted on the top of the steel frame 1. In this embodiment, the mixer 9 is a spiral mixer. The spiral mixer causes the powder to convect within the container through the rotation of the spiral blades, thereby achieving a high-efficiency mixing effect. Moreover, the mixer usually adopts frequency conversion speed regulation, which is flexible in operation and can adjust the speed according to different material characteristics and mixing requirements. The powder mixed by the spiral mixer is discharged from its bottom discharge port and transferred to the powder packaging scale 10. The powder packaging scale 10 weighs the powder according to a certain weight, and finally packages it to complete the production of powder water-soluble fertilizer.

[0028] Please see Figure 1In actual production, the powder fed into the feed port 2 is often not uniform enough, and the crushing effect of the bar crusher alone is often not achieved. In this utility model, a second crusher 11 is also provided between the first crusher 3 and the first weight reduction chamber 4. The outlet of the first crusher 3 is connected to the second crusher 11 through the installation of the transition chamber 12, and the outlet of the second crusher 11 is then connected to the first weight reduction chamber 4. A straight discharge screen 13 for screening powder is also installed at the outlet of the second crusher 11. More specifically, in this embodiment, the second crusher 11 is a plate crusher. Since the rod crusher is used for coarse and medium crushing and can only process larger pieces of powder, the powder after being crushed by the rod crusher cannot meet the particle size requirements of the finished powder product. Therefore, it needs to be further crushed by the plate crusher. The plate crusher is suitable for fine and ultrafine crushing and can crush the powder to a smaller particle size. However, directly crushing the powder with the plate crusher may cause high energy consumption and equipment wear. Pre-treatment by the rod crusher can reduce these adverse factors. At the same time, a straight discharge screen 13 is also installed at the outlet of the second crusher 11. The straight discharge screen 13 can screen out some impurities or unqualified particles that may be contained in the powder, prevent excessively large particles from entering the downstream equipment, reduce the risk of equipment blockage, ensure the continuous and stable operation of the production line, and improve the purity and quality of the product.

[0029] Please see Figure 1 When the powder after the second crushing enters the first weight reduction bin 4, the poor flowability of the powder will cause the formation of arches in the bin. In this utility model, the first weight reduction bin 4 is equipped with an arch breaking device 14. The arch breaking device 14 disturbs the powder in the weight reduction bin by means of mechanical vibration, air pressure pulse or rotating mechanical arm, etc., to help the powder restore its flowability and avoid the bin blockage.

[0030] Please see Figure 1Since urea is a hygroscopic chemical, it is prone to caking in humid environments, which affects its flowability. Therefore, in order to prevent urea from caking and being difficult to mix, this utility model also includes a urea distribution hopper 15 installed on the top layer of the steel frame 1. The discharge port of the urea distribution hopper 15 is connected to the urea crusher 16, the discharge port of the urea crusher 16 is connected to the third weight reduction hopper 17, and the third weight reduction hopper 17 is connected to the conveyor 6. During the production process, the urea feeding hopper 15 mainly serves as a buffer to balance the difference between urea supply and consumption, ensuring the stable operation of the production line. The urea feeding hopper 15 evenly distributes the urea to the urea crusher 16 below it. The urea crusher 16 is different from the first crusher 3 and the second crusher 11. Due to the low hardness of urea, the crusher design needs to reduce wear on the material to reduce material loss. In addition, dust is easily generated during the urea crushing process. The urea crusher 16 is usually designed with a dust collection system to prevent dust pollution. The crushed urea enters the third weight reduction bin 17, and the third weight reduction bin 17 then transports the urea to the conveyor 6 through the weighing system.

[0031] Please see Figure 1 In the production process of water-soluble powder fertilizer, some powder materials require preliminary treatment before entering the final mixing stage. This invention also includes a dust collection and feeding station 18 installed on the top layer of the steel frame 1. The outlet of the dust collection and feeding station 18 is connected to a premix mixer 19, and the outlet of the premix mixer 19 is connected to a fourth weight-reducing bin 20. The fourth weight-reducing bin 20 is connected to a conveyor 6. The powder materials requiring premixing will generate a large amount of dust during the feeding process. The dust collection system in the dust collection and feeding station 18 collects this dust to prevent it from spreading into the workshop. Simultaneously, the powder materials mixed by the premix mixer 19 help improve the uniformity of the final mixing effect during the final mixing stage. The premixed powder materials enter the fourth weight-reducing bin 20 and are then distributed to the conveyor 6 through the weighing system of the fourth weight-reducing bin 20.

[0032] Please see Figure 1 After the powder is mixed, to ensure the airtightness of the packaging, in this invention, the powder packaged by the powder packaging scale 10 falls onto the belt conveyor 21. A heat sealing machine 22 and a folding and sewing machine 23 are installed along the conveying path of the belt conveyor 21. The qualified powder from the powder packaging scale 10 falls onto the belt conveyor 21, which sequentially sends the powder to the heat sealing machine 22 and the folding and sewing machine 23 for sealing and packaging, preventing spillage and moisture absorption.

[0033] Please see Figure 1In order to package the sealed powder, in this invention, the conveying end of the belt conveyor 21 is connected to the inclined conveyor 24. The inclined conveyor 24 transports the powder to the packing platform 25, which is equipped with a matching box sealing machine 26. The sealed packaged water-soluble fertilizer is transported to the packing platform 25 by the inclined conveyor 24 for packing, and then sealed by the box sealing machine 26, thus completing the water-soluble fertilizer production process.

[0034] Please see Figure 1 To prevent excessive dust in the workshop, a dust collector 27 is installed at the feeding port 2 in this invention. During the production of water-soluble powder fertilizer, a large amount of dust is generated during loading, unloading, conveying, and storage of the powder. This dust is harmful to the health of operators and accumulates on equipment and electrical components, leading to equipment wear and poor heat dissipation. Furthermore, dust affects the product quality of the water-soluble powder fertilizer. Therefore, installing a dust collector 27 at the feeding port 2 can minimize dust and ensure continuous production in the workshop.

[0035] Please see Figure 1 Since the feeding port is located on the top floor of the steel frame 1, and the equipment is also installed on a different floor from the steel frame 1, in this utility model, the steel frame 1 is equipped with a hydraulic lifting platform 28, which can reach any floor of the steel frame 1. The hydraulic lifting platform 28 facilitates the operation of workers to transport powder to the top floor of the steel frame 1 for feeding, and also facilitates maintenance workers to perform routine inspections or maintenance on the equipment on each floor.

[0036] The advantages of this utility model are:

[0037] 1. This utility model rationally arranges the feeding port, the first crusher, the first weight reduction bin, the bucket elevator, the second weight reduction bin, and the mixer on a steel frame, and makes efficient use of gravity to transport powder materials, which not only saves transportation costs, but also improves the utilization rate of the workshop floor space.

[0038] 2. This utility model also includes a powder packaging scale, belt conveyor, heat sealing machine, folding and sewing machine, inclined conveyor, packing platform and sealing machine, which integrates the production and packaging of water-soluble powder fertilizers into a fully automated process, thereby improving production efficiency.

[0039] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
