Description

Technical Field

[0001] This utility model belongs to the field of fertilizer production technology, specifically relating to a powder fertilizer production system. Background Technology

[0002] With the rapid development of modern agriculture, the demand for efficient and environmentally friendly fertilizers is increasing. Powder fertilizers have emerged in this context. As a new type of water-soluble fertilizer, it can not only be quickly absorbed and utilized by plants, but also significantly improve crop yield and quality. Powder fertilizer, also known as powdered drip irrigation fertilizer, refers to a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc., that can be completely dissolved in water. Based on nutrient content, powder fertilizers can be classified into macro-element powder fertilizers, meso-element powder fertilizers, micro-element powder fertilizers, amino acid powder fertilizers, humic acid powder fertilizers, and organic powder fertilizers, among others.

[0003] Powder fertilizer is a fast-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and directly absorbed and utilized by the roots and leaves of crops. Moreover, it has a rapid effect and can meet the nutritional needs of high-yield crops during their rapid growth period. In addition, when used with a drip irrigation system, the water requirement is only 30% of that of ordinary chemical fertilizers, and the fertilization operation greatly saves labor costs. Therefore, powder fertilizer has obvious advantages compared with traditional varieties such as superphosphate and granulated compound fertilizer.

[0004] Currently, powder fertilizer production lines typically use weighing scales and static metering methods to dispense raw materials, which makes it difficult to effectively adjust the dispensing speed and quantity, and the low level of automation results in low production efficiency.

[0028] This application provides a powder fertilizer production system, such as Figure 1 As shown, it includes a batching system, a mixing and screening system, and a packaging system.

[0029] The batching system includes several belt scales, each equipped with a speed controller to control its speed. Each belt scale dispenses a specific amount of powdered fertilizer raw material according to a given formula. As those skilled in the art will understand, the belt scales are equipped with speed sensors and weighing sensors. These sensors detect the dispensing speed and the weight of the material placed on the scale, respectively. The obtained belt speed and weight information allows for continuous dynamic measurement of the material. Each belt scale automatically dispenses one type of powdered fertilizer raw material according to the formula.

[0030] Preferably, the batching system further includes several crushing devices 2 and feeding hoppers 3, each corresponding in number and location to the belt scale. The feeding port of the crushing device 2 is connected to the feeding hopper 3, and the feeding port of the feeding hopper is connected to the feeding port of the corresponding belt scale. The crushing device 2 is used to crush the powdered fertilizer raw materials to the target particle size, temporarily store them in the feeding hopper 3, and then distribute them via the belt scale. The crushing devices can be cage crushers, toothed roller crushers, etc.

[0031] More preferably, the batching system further includes a first elevator 1, which is used to transport the powdered fertilizer raw materials to the crushing device 2.

[0032] The mixing and screening system, including the mixing and screening device 6, is used to mix and screen the powdered fertilizer raw materials supplied by the batching system, remove large particles, and obtain qualified products. The mixing and screening system can ensure that the particle size of the products meets the requirements and that the products are uniform.

[0033] The mixing and screening device 6 preferably adopts a drum-type mixing and screening device.

[0034] Preferably, the mixing and screening system further includes a dust collection device 10 connected to the mixing and screening device 6, which is used to collect and remove dust during the mixing and screening process to improve the on-site working environment.

[0035] The packaging system includes a finished product silo 8 and a packaging unit 9. The finished product silo 8 has a discharge port for unloading. Qualified products after screening are first transported to the finished product silo 8 for storage, and then transported to the packaging unit 9 through the discharge port. The packaging unit packages the qualified products according to the product packaging specifications. The finished product silo 8 is equipped with a level gauge to detect the material level within the silo. A single production line can be equipped with multiple packaging units.

[0036] Preferably, a vibration device is provided at the discharge port of the finished product silo 8 to ensure smooth material discharge.

[0037] Preferably, a discharge control valve is provided at the discharge port to facilitate the control of material discharge.

[0038] Preferably, the production system provided in this application further includes a first conveying system and a second conveying system; the first conveying system is used to convey the raw materials delivered by each belt scale to the mixing and screening system; the second conveying system is used to convey qualified products to the packaging system.

[0039] More preferably, the first conveying system includes a sealed scraper conveyor 4, a horizontal conveyor, and a second elevator 7. Each belt scale is equipped with a sealed scraper conveyor, and the horizontal conveyor 5 is arranged along one side of each belt scale. That is, the horizontal conveyor passes through each belt scale, and the sealed scraper conveyor can transport the material delivered by each belt scale to the horizontal conveyor 5. Then, the horizontal conveyor 5 transports each material to the second elevator, and the second elevator transports the material to the mixing and screening device 6.

[0040] Using a sealed scraper conveyor can prevent the spread and loss of powder materials during the conveying process, and also reduce environmental pollution.

[0041] The second conveying system includes a third elevator 7; the third elevator 7 is used to convey qualified products screened by the mixing and screening device 6 to the finished product silo 8.

[0042] Because the finished product silo 8 is equipped with a level gauge, it can detect the amount of material stored in the silo. This allows for timely adjustment of the feeding speed of each belt scale via a speed controller, preventing the silo from overflowing with too much qualified product per unit time, and also preventing the silo from becoming too empty, thus reducing production efficiency. Specifically, when the level gauge detects low material levels in the silo, the feeding speed and quantity can be increased, and the speed controllers can be adjusted to increase the belt scale speed. Conversely, when the level gauge detects high material levels, the feeding speed and quantity can be reduced, and the speed controllers can be adjusted to decrease the belt scale speed.

[0043] Preferably, the production system provided in this application further includes a control system. The speed controller and level gauge are both electrically connected to the control system. The control system controls the speed controller based on the level gauge's detection information, thereby automatically controlling the conveyor belt speed. Specifically, when the level gauge detects a low material level in the finished product hopper, it automatically controls each speed controller to increase the belt scale's operating speed. Conversely, when the level gauge detects a high material level in the finished product hopper, it automatically controls each speed controller to decrease the belt scale's operating speed, thus achieving automatic adjustment of the batching speed and quantity.

[0044] Therefore, the powder fertilizer production system provided in this application adopts dynamic metering and batching with belt scales and finished product level detection, realizing automatic batching and automatic adjustment of batching speed according to finished product buffer quantity, improving the automation level of the production line, simplifying the production process, reducing the labor intensity of workers and improving the working environment, while also improving the quality and output of powder fertilizer products.
